Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a forward and reverse dual-purpose gluing mechanism of a coating machine. Background Art

[0002] Coating machines are mainly used for surface coating production of films, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then cuts it into sheets or reels it after drying.

The utility model is provided with a positive coating scraper 3, and the cloth pressing roller 2 presses the cloth onto the glue transfer roller 1. During the gluing process, the glue on the glue transfer roller 1 is smoothed by the positive coating scraper 3 and then the glue is evenly transferred to the cloth. The utility model mechanism is further provided with a reverse coating scraper 4 to scrape the glue on the cloth flat again, making the gluing more uniform and recovering excess glue. The thickness of the glue is easy to control, which is beneficial to saving costs and preventing glue overflow at the edges.

[0028] Furthermore, the forward coating bracket 31 and the reverse coating bracket 41 are respectively provided with a forward coating angle adjustment device 5a and a reverse coating angle adjustment device 5b, and the forward coating blade 3 and the reverse coating blade 4 are respectively installed through the forward coating angle adjustment device 5a and the reverse coating angle adjustment device 5b.

[0029] Furthermore, the positive coating angle adjustment device 5a includes an adjustment cylinder 5a1 whose cylinder body is hinged to the positive coating bracket 31 and a blade clamp 5a2 for clamping the positive coating blade 3.

The structure of the reverse coating angle adjustment device 5b is the same as that of the positive coating angle adjustment device 5a. Specifically, as Figure 7 、 8 As shown, the clamp connecting plate 5a5 is hinged on the scraper bracket 5a4, and the scraper clamp 5a2 at one end of the clamp connection will be pressed downward under the action of its gravity, and the adjustment drive plate 5a3 at the other end of the clamp connecting plate 5a5 will be tilted up.

Specifically, during the process of coating and scraping glue, the glue on the glue transfer roller 1 will overflow to both ends to form two raised glue marks, which will affect the thickness of the glue. To solve this problem, the coating transverse motor 01f drives the eccentric shaft to rotate, thereby driving the rolling bearing 01g to rotate around the rotating shaft of the coating transverse motor 01f. Combined with the "I"-shaped drive block 332 and the transverse drive rod 331, it drives the entire coating propulsion bracket 321 to perform reciprocating transverse motion. When coating and scraping glue, it drives the coating scraper to move back and forth transversely to evenly scrape the overflowed glue at both ends of the glue transfer roller 1 to ensure uniform glue thickness.
