Correct operation process of window pasting machine

1 Preliminary preparation

1.1 production of gluing template

according to the size of the paper film pasting window, select a 0.5mm thick polytetrafluoroethylene gluing plate from the width of 300mm-720mm respectively, align one edge of the paper to be pasted with the side of the gluing plate, then draw the window contour line on the gluing plate along the window with a marker, take away the paper, and draw a 5mm wide gluing position line along the window contour line on the gluing plate with a marker. Use 2mm thick double-sided adhesive tape to stick the upper rubber strip on one side and the rubber strip on the gluing position on the other side. At the same time, in order to firmly bond the rubber strip with the upper offset plate, use adhesive paper to stick a layer around the bottom of the rubber strip. After the gluing template is assembled, its thickness is about 10mm

insert the hook bar at one end of the offset plate into the groove of the plate roller, and stick the other end with the plate roller with viscose paper to make the offset plate tightly wrap on the outer surface of the plate roller

1.2 installation of cutter

turn the cutter roller to the top manually, put the upper blade into the cutter groove of the cutter roller, make the lower end of the blade fully contact with the bottom of the cutter groove, and then tighten 18 M6 15 set screws from the middle to both sides

when installing the lower blade, insert the blade into the tool holder seat through the through hole of the machine body, slightly tighten one screw in the middle and two screws at both ends with a wrench, turn the cutter roll manually, stop the turning when the blade edge of the upper blade is turned to the lower part and aligned with the blade edge of the lower blade, and adjust 19 M8 110 screws one by one with a wrench to control the gap between the upper blade and the lower blade at 0 After 05mm, tighten 18 M10 95 screws to make the pressing plate press the lower knife, and then tighten M8 nuts

the cutting edges on both sides of each cutting blade can be used alternately. When the cutting edge of the blade becomes blunt, it is necessary to grind the two planes to continue to use. Generally, new blades are installed in the cutter roller. The protruding height of the lower blade can be adjusted by M8 110 screws to control the gap between the lower blade and the upper blade

the clearance adjustment of the upper and lower blades must be very careful, otherwise it will cause damage and rapid wear

1.3 preparation of film and glue

the films pasted on the window are mostly polypropylene (PP) and polyethylene (PE), and the width of the film roll is generally about mm wider than the window. The whole roll of diaphragm opened in advance according to the width of the window on the paper is installed on the material rack device at the tail of the host. The length of the diaphragm is generally 30mm longer than the length of the window

different diaphragms shall be equipped with corresponding glue. Generally, water-soluble white glue shall be selected. The glue shall comply with environmental protection standards and shall not contain toxic substances and substances that will not harm the ozone layer. The premise of its allocation is based on the glued film

2. With high safety and reliability, adjustment and operation

2.1 paper feeding

after finishing the paper to be coated after die cutting and indentation, stack it obliquely on the paper feeding table with supporting feet, pull out the lowest paper from the paper pile during the rotation of the paper feeding belt, and enter the paper feeding device after passing between the paper feeding belt and the pressing wheel with the rotation of the paper feeding belt

2.2 conveying of paper products

after the paper products enter the paper feeding device through the paper feeding belt, the paper products are pushed forward by the paper pushing stop gauge on the chain, and sent to the vacuum conveyor belt of the gluing device along the guiding devices of the upper and lower guide rails and left and right guide rails with adjusted distance

due to the change of processed paper specifications and different window positions, the paper conveying position needs to be adjusted

paper feeding position adjustment

select the paper feeding position according to the shape of the processed paper, loosen the tensioning wheel of the paper feeding belt, move the paper feeding belt to the required position and fix it. Loosen the star handle on the roller frame, move the paper pressing roller on the roller frame, align the conveying wheel with the paper pressing roller, and then tighten the star handle

adjustment of paper conveying position

when the film coated paper is pushed by the paper pushing stop gauge on two conveying chains at the same time, or when two paper pushing stop gauges are required in order, loosen the screw on the sprocket and pull the chain by hand. At this time, the sprocket in the empty sleeve rotates over the driving shaft, which can drive the paper pushing stop gauge on the chain to move back and forth, adjust the stop gauge to the appropriate position that is about to be pushed to the paper jam, and then lock the screw

2.3 adjustment of gluing device

adjustment of gluing amount

loosen the two star handle screws and rotate the two handles on the left and right sides of the small wallboard at the same time on both inner sides to adjust the gap between the rubber transfer roller and the glue roller. When the handle rotates upward, the gap between the two rubber rollers is small, the gluing amount is small, on the contrary, when the handle rotates downward, the gluing amount is large. After adjusting the appropriate glue amount, tighten the star handle screws

in order to avoid the condensation of glue on the glue roller and rubber transfer roller during shutdown, a four ball friction and wear tester is equipped on the glue roller. The things needing attention are the motor. When the host machine is shut down, the motor starts and the glue roller and rubber transfer roller continue to rotate

2.4 gluing

the paper is transported by eleven flat belts with holes at the gluing and film pasting station. The suction pump generates negative pressure and adsorbs the paper jam on the moving conveyor belt through the small hole on the flat belt to keep the paper jam in the correct position and enter the gluing part. The glue roller transmits the glue liquid to the glue roller, which then applies the glue liquid to the rubber strip of the plate. When a paper product is transported to the lower part of the plate drum for glue, the two electromagnetic suction irons on the inner side of the left and right wallboards drive the lever to force the suction paper table to rise, and the glue liquid on the rubber strip is correctly applied to the window of the paper product through the rotation of the drum

gap adjustment between the rubber transfer roller and the plate roller

pull the handle down, and then rotate the two star handle screws on the top of the small wall panel to adjust the gap between the rubber transfer roller and the plate roller. Rotate the star handle screw counterclockwise to reduce the gap between the rubber transfer roller and the plate roller and increase the amount of glue; On the contrary, the gap increases and the gluing amount decreases. If you do not need to pull the glue on the roller, you can stop it

gap adjustment between the plate roller and the flat conveyor belt

loosen the two handles on the outside of the wallboard on the operation surface and the inside of the wallboard on the transmission surface, rotate the two spherical handles respectively to move the plate roller up and down, so as to change the gap between the plate roller and the flat conveyor belt to adapt to paper products of different thickness, and then lock the two handles

If the gap between the plate roller and the conveying flat belt is adjusted too small, the glue liquid on the rubber strip of the upper offset plate will be pasted to the conveying flat belt through the rotation of the roller, affecting the working state of the conveying flat belt

air volume adjustment and control of the paper feeding table

the paper products are sent to the vacuum flat belt conveying table driven by the chain conveyor block. There are eleven annular paper conveying belts on the table. When the air suction motor is started, the air is sucked through the small hole on the paper conveying belt and the paper products run with the paper conveying belt. There are ten adjusting screws on the paper feeding table to adjust the air suction, including nine adjusting screws arranged in a straight line, which rotate the screws clockwise, The suction air volume can be reduced or closed. On the contrary, rotate counterclockwise to increase the suction air volume. There is an adjusting screw, which rotates counterclockwise to reduce or close the suction air volume

when the paper jam width is less than the width of multiple adjusting screws on the paper feeding table, the unnecessary air holes can be closed by rotating the adjusting screw to increase the effective wind force

adjustment of the circumferential position of the plate roller

install the offset plate on the plate roller, apply the ink of the printing table on the rubber strip, jog the machine, push the paper to the adhesive position through the chain push paper stop gauge, and print the ink on the window of the paper with the rotation of the plate roller. According to the difference between the relative position of the window to be coated on the paper and the plate, loosen the M8 set screw on the plate roller on the inner side of the wall panel of the operation surface, Rotate the plate roller to adjust the circumferential position, so that the rubber strip of the upper plate is aligned with the front and rear positions of the film window, and then lock the M8 set screw

if there is a difference between the left and right relative positions of the ink printed on the window of the paper jam and the window to be coated on the paper jam, properly adjust the paper feeding positioning side gauge and the paper feeding positioning block, and the plate roller can also be fine tuned left and right

2.5 film coating

film coating consists of four steps: film feeding, film cutting, film transmission and film coating. Install the whole roll of film opened in advance according to the width of the window on the paper jam on the material rack device at the tail of the host. The length of the film is generally 30mm longer than the length of the window, and the width of the film roll is about mm wider than the window. According to the window length of the required film on the paper, the diaphragm is continuously output by a pair of film feeding rubber and power rollers according to the preset speed through the stepless governor, and then sent to the film cutting roller and cut through the knife edge. At the same time of cutting, the diaphragm is absorbed and transferred by the film pressing transfer roller. When it is accurately opposite to the window of the paper, it changes from suction to blowing on the film pasting roller due to the action of the air valve, The film is rolled with the cardboard and the film is sent out

adjustment of film cutting length

the film cutting length is generally 30mm longer than the window length, and the film roll width is about 30mm wider than the window. The cutting length of the diaphragm is within the range given by the machine and can be adjusted according to the window size of the paper jam. The transmission side of the machine is equipped with a stepless governor with digital scale adjustment. The sprocket coaxial with the gear on the cutter roller drives the sprocket on the input shaft of the stepless governor. After deceleration, it is output by the output sprocket to drive the sprocket of the film feeding power roller, so that the power roller and the cutter roller maintain the set speed relationship, so that the cut diaphragm is a certain length, which can be adjusted to the required length by adjusting the handwheel. The cutter will cut the fixed length diaphragm stably

it is forbidden to rotate the adjusting hand wheel when it is stopped, otherwise it may cause damage to the continuously variable transmission

installation and adjustment of diaphragm width direction

install the diaphragm roll on the material rack shaft, push the handle on the wall panel counterclockwise to loosen the rubber roller, pass the diaphragm through the lower blade, and then loosen the handle, and the diaphragm is transported out with the rotation of the machine. When the transported diaphragm is pasted on the paper window, and the offset of "large belt leading to small and small leading to large" is realized in the width direction, loosen the three M6 screws at both ends of the diaphragm material roll to move the relative position of the diaphragm roll on the material rack shaft, align the diaphragm with the paper jam window, loosen M10 nuts and knurled nuts, and rotate the adjusting hand wheel to realize the fine adjustment of the position of the paper jam window by the material roll diaphragm. After the adjustment is completed, lock the screws and nuts. If the diaphragm is too wide, use the cutter to cut the diaphragm to the required width. If the diaphragm needs indentation, the heating device can be adjusted to indentation the diaphragm

control and adjustment of the air volume of film cutting roller and film coating roller

there are three handles on the suction air separation block and the blowing air separation block respectively, which are air volume adjustment switches. When the valve core at the handle is horizontal, it is closed. When the valve core at the handle is vertical, the air volume is the maximum

adjustment of the position of the paper window on the diaphragm and the conveying flat belt

when the paper is transported to the film pasting station, if the diaphragm and the film pasting window on the paper are staggered back and forth, stop the machine, long press the adjustment button on the middle button board, release the handle on the outside of the wall panel of the operation surface, and turn the adjustment hand wheel counterclockwise according to the position of the diaphragm and the paper to make the paper reach the film pasting position in advance; On the contrary, after the position of the diaphragm pasted on the paper window is late, turn the handwheel clockwise to make the paper reach the film pasting position slowly. When the position of the film is correct, lock the handle, and the film can be pasted normally after gluing

2.6 adjustment of paper output collection position

the paper with finished window film is leveled by the conveyor黑龙江益母草颗粒用药注意事项
