Description

Technical Field

[0001] This application relates to the field of plastic film laminating machine technology, and more specifically, to an adhesive coating device for a plastic film laminating machine. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used for various daily necessities. They are widely used in daily life and industrial production. Plastic bags are mostly made of polyethylene film. First, ink is printed and laminated, then the bags are made. After printing, the plastic film needs to be coated with glue and then laminated with the inner or outer layer of the plastic bag.

[0003] In the prior art, there is a coating device for a plastic film laminating machine with application number CN202121315220.5. However, in the above solution, "a roller drives three coating plates to rotate, and the three coating plates coat the plastic film with glue. When the coating plate passes the sponge block, the glue on the coating plate is replenished. When the coating plate passes the scraper plate, the scraper plate scrapes off the excess glue on the coating plate. The excess glue falls into the collection box for easy recycling. By rotating the bolt, the scraper plate can be moved horizontally. By controlling the size of the gap between the scraper plate and the coating plate, the thickness of the glue on the coating plate can be adjusted." The glue is in a liquid state. When the scraper plate scrapes the glue on the coating plate, the glue will flow to both sides when scraping from the front. This results in more glue on the sides during application, which is easy to accumulate on the plastic film. The glue accumulation makes it difficult to dry and easy to stick to other films. Excessive glue can also cause the film to bulge when the glue dries, resulting in product defects.

[0004] To address the aforementioned problems, this application provides an adhesive coating device for a plastic film laminating machine. Utility Model Content

[0031] The base plate 41 is used to scrape off the accumulated glue, and the blocking member 411 cooperates with the base plate 41 to collect the scraped glue.

[0032] The stop block 42 is attached to the outside of the vertical plate 2, the T-shaped block 421 is slidably engaged with the T-shaped groove 21, and one end of the electric push rod 4211 is fixedly connected to the top wall of the T-shaped groove 21.

[0033] T-block 421 is used to limit the stop block 42 and prevent the stop block 42 from dislodging from the side of the vertical plate 2. Electric push rod 4211 is used to push T-block 421 to slide along T-slot 21.

[0034] The outer end of the rotating shaft 31 is rotatably engaged with the inner end of the vertical plate 2, and a limiting groove 321 is provided on the inner wall of the annular groove 32.

[0035] The rotating shaft 31 is used to drive the glue-applying wheel 3 to rotate via a motor inside the vertical plate 2. The glue-applying wheel 3 is used to apply glue to the material.

[0036] The arc-shaped block 5 is rotatably connected to the annular groove 32, the limiting block 51 is rotatably engaged with the limiting groove 321, and the conveying plate 52 is attached to the outer surface of the coating wheel 3.
