Description

Technical Field

[0001] The utility model relates to the technical field of paper cup processing, and specifically relates to a film laminating machine for paper cup processing. Background Technique

[0002] A paper cup is a paper container made by mechanically processing and bonding the base paper made of chemical wood pulp, and its appearance is in the shape of a cup. Paper cups have the characteristics of being convenient to carry, use, and low in price, and are common liquid containers in many families and public places. Paper cups are classified into cold drink cups, hot drink cups, yogurt cups, etc. according to their uses. Paper cup film laminating mainly uses a transparent plastic film to be thermally pressed and adhered to the surface to protect the pattern and increase the gloss of its surface.

[0003] In the production process of paper cups, the film laminating process is one of the key steps. This link requires precise covering of the plastic film on the surface of the paper cup to ensure that the paper cup has sufficient waterproof performance and durability. However, many existing film laminating machines only adopt single-time film laminating technology, such as the utility model with the patent number CN218171559U. Only a single film laminating roller is equipped inside this device, resulting in uneven thickness of the film covered on the surface of the cardboard, which affects the overall quality and appearance of the product. Secondly, when the amount of coating in the storage tank decreases, the film laminating roller may rotate idly, meaning that it cannot continuously provide the necessary coating for the cardboard, thereby affecting the production efficiency and the finished product rate.

At the end of the feed pipe 9 away from the feed inlet 10, there is a water pump 8. At the top of the water pump 8, there is a Y-shaped conduit 7. At both ends of the Y-shaped conduit 7 away from the water pump 8, there are connecting pipes 19 connected. At the end and the middle part of the connecting pipe 19 away from the Y-shaped conduit 7, there are several spraying ports 18. On one side of each spraying port 18 close to the Y-shaped conduit 7, there is a scraper 16. At both ends of each scraper 16, there are third fixing blocks 15. On the side of each scraper 16 away from the spraying port 18, there is a film laminating roller 5. Above the film laminating roller 5, there is a cardboard 2. On the cardboard 2, there are several pressing rollers 17. The pressing rollers 17 cooperate with the film laminating roller 5 to laminate the cardboard 2, and at the same time, the spraying ports 18 spray the coating onto the film laminating roller 5, always keeping the coating on the film laminating roller 5.

[0025] Furthermore, there are several baffles 12 between the connecting pipes 19. The baffles 12 are provided with several openings 14. The baffles 12 are used to block the coating to prevent the coating from splashing onto the housing 1, and the openings 14 facilitate the film laminating roller 5, the spraying ports 18, the scrapers 16, and the third fixing blocks 15 to pass through the baffles 12.

[0026] Furthermore, on one side of the third fixing block 15, there is a slotted opening 21, which is convenient for fixing the scraper 16.

[0027] Furthermore, at both ends of the spraying port 18, there are second fixing blocks 13. On the Y-shaped conduit 7, there are several first fixing blocks 6.
