Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a hot melt adhesive coating roller for bag making machines. Background Art

[0002] With the continuous improvement of people's living standards, packaging bags have become an indispensable packaging product in people's lives. This requires bag-making equipment to make a whole roll of film into a single large packaging bag. One part of the existing bag-making process is to use a single roll of film to output and then fold the packaging film into a bag shape through a film folder or a film folding plate, and then seal it longitudinally and transversely, and cut it to form an independent single packaging bag. If it is not cut, it can form a packaging bag roll. Another part uses two rolls of film, one roll of film as the upper film and the other roll of film as the lower film. After being guided and conveyed separately, they are overlapped at the appropriate position. The overlapping upper and lower films are sealed transversely and longitudinally to form multiple bag structures. Finally, they are cut by a cutter to form multiple bag bodies. In this process, the packaging film is bonded together by a coating roller.

[0003] The current equipment cannot be adjusted according to actual conditions during use, which may result in excessive or insufficient glue being applied during the production of packaging bags, thereby reducing the production quality of the products.

[0040] The implementation principle of this embodiment is:

[0041] The bag making machine uses a hot melt adhesive coating roller, which is provided with a support roller 3. When using the equipment, the staff passes the packaging film through the support roller 3, then passes around the top of the coating roller 10, and passes through the support roller 3 again near the side of the motor 4. Then, the staff rotates the threaded rod 12. Since the threaded rod 12 is threadedly connected to the threaded block, and the threaded block is restricted from rotating inside the slide groove 8, the threaded rod 12 can drive the threaded sleeve 13 to move when rotating. The threaded sleeve 13 moves up and down, which can drive the mounting plate 14 to move. The movement of the mounting plate 14 can drive the mounting block 16 to move up and down. The up and down movement of the mounting block 16 can drive the coating roller 10 to move up and down, which can enable the coating roller 10 to lift the packaging film, so that the packaging film can always be in a tensioned state, thereby preventing the packaging film from wrinkling, thereby improving the production quality of the product.

[0042] Afterwards, the staff rotates the screw rod 19. Since the screw rod 19 is threadedly connected to the mounting plate 14, and the screw rod 19 is rotationally connected to the movable plate 18, the movable plate 18 can be driven to move up and down when the screw rod 19 rotates. The up and down movement of the movable plate 18 can push the spring 17. Since the mounting block 16 does not move under the pressure of the coating roller 10, the spring 17 can be deformed, and the elastic force of the spring 17 can be adjusted to a certain extent, and the amount of glue on the packaging film can be adjusted. In addition, due to the presence of the spring 17, the pressure on the packaging film can be averaged, and the amount of glue on the packaging film can be the same, thereby improving the production quality of the product.

[0043] Afterwards, the staff starts the motor 4, and the motor 4 starts working, which can drive the supporting roller 3 to rotate. The rotation of the supporting roller 3 can drive the packaging film to move, and the movement of the packaging film can drive the coating roller 10 to rotate. During the rotation of the coating roller 10, the glue can be applied to the bottom of the packaging film, and some of the glue will remain on the outer surface of the coating roller 10. As the coating roller 10 rotates, the cleaning plate 23 can clean the outer surface of the coating roller 10, and then the glue on the outer surface of the coating roller 10 can be scraped off, thereby ensuring the cleanliness of the outer surface of the coating roller 10, thereby preventing uneven glue coating, thereby improving the production quality of the product, and the scraped glue will return to the inside of the glue pool 6 through the baffle 24 and the guide groove 25, thereby avoiding waste.

[0044] When the cleaning plate 23 needs to be cleaned, the staff turns the screw 31, and the screw 31 will disengage from the inside of the screw hole 32, so that the limiting plate 30 can be moved. Then, the staff pulls the limiting plate 30, and the movement of the limiting plate 30 can drive the fixed plate 22 to move, and the movement of the fixed plate 22 can drive the cleaning plate 23 to move. When the fixed plate 22 is completely pulled out, the staff pulls the cleaning plate 23. Since a connecting block 27 is provided at the bottom of the cleaning plate 23, and the connecting block 27 can slide inside the connecting groove 26, the cleaning plate 23 can be pulled out, and the cleaning plate 23 can be cleaned and replaced, thereby extending the service life of the equipment.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. The hot melt adhesive coating roller of the bag making machine is provided with an adjustment mechanism 9. By rotating the threaded rod 12, the threaded sleeve 13 can be driven to move, thereby adjusting the position of the coating roller 10, thereby keeping the packaging film in a tensioned state at all times, thereby improving the production quality of the product. The coating roller 10 adopts an electric heating roller design to prevent the glue from solidifying. By rotating the screw rod 19, the movable plate 18 can be moved, thereby adjusting the elastic force of the spring 17, thereby making the glue on the packaging film more evenly distributed, thereby improving the production quality of the product.

[0047] 2. The hot melt adhesive coating roller of the bag making machine is provided with a cleaning mechanism 11. The coating roller 10 can be cleaned by the cleaning plate 23. The scraped glue can flow into the interior of the glue pool 6 through the baffle 24 and the guide groove 25, so that the glue can be reheated, thereby ensuring the cleanliness of the outer surface of the coating roller 10, thereby preventing glue residue on the outer surface of the coating roller 10, thereby improving the production quality of the product. The fixing plate 22 can be disassembled and installed through the screws 31 and the limit plate 30, thereby enabling the cleaning plate 23 to be replaced and cleaned, thereby improving the production quality of the product.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
