Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 to 3, the utility model provides a technical solution for a film coater with adjustable glue thickness: a film coater with adjustable glue thickness, including a discharge roll 1 and a support discharge roll 1 On the bottom plate, the melt glue box 11 located on the upper right side of the unwinding roll 1 is fixed on the bottom plate through the support plate, and the lower ends of the left and right walls of the melt glue box 11 are provided with gaps corresponding to the film wound on the unwinding roll 1. Material hole 12, the film passes through the material hole 12 against the bottom of the melt box 11, and the other end of the film is connected with a winding device, which is a prior art and will not be described in detail.

The glue tank 11 is fixed with a divider 2 with a glue penetration hole for slowing down the pressure of the glue. The divider 2 prevents the glue pressure from being too high and causes the glue to leak too fast, and the divider 2 divides the melt tank 11 into The sol chamber on the upper side and the coating chamber on the lower side, the lower end of the partition 2 is fixed with a glue coating component with a gap between the film and the film, which can pass through the glue and absorb the glue. The glue coating component is a sponge block 21 In this way, the water will not flow down too fast, and at the same time, the glue will be absorbed, and it will not directly drip onto the film, but will be scraped by the film, and continue to seep down to realize glue application. The width of the hole 12 here is the same as that of the melt box The width of the front and rear walls of 11 is always constant, and the right side of the gluing assembly is provided with a glue thickness adjustment mechanism for scraping glue that changes the distance from the film by adjusting the height up and down.

The film is torn off from the unwinding roll 1, penetrates the material hole 12 in the melt tank 1, and is pulled by the winding device, where the melt tank 11 ensures that the glue is liquefied and flows along the glue penetration hole on the partition 2 On the sponge block 21, the separator 2 ensures that the pressure of the infiltrated glue will not be too large, and the sponge block 21 ensures that the glue slowly infiltrates, and then a part protrudes through the sponge block 21, enters the glue coating gap, and is absorbed and not It will fall too fast, and the moving film will adhere to the glue, so that the glue will continue to seep down in the sponge block 21, supplement it, and continue to apply glue to the film. The distance between the scraper 22 and the film is the thickness of the glue. Turn the rotary block 24 to drive the threaded rod 23 to rotate, and the scraper 22 can be moved up and down to adjust the distance between the scraper 22 and the film to scrape off excess glue. To the sponge block 21, thereby changing the thickness of the glue, so that the thickness of the glue can be adjusted, the amount of glue on the film can be changed, the viscosity can be changed, and the use is more convenient.

The glue thickness adjustment mechanism includes a scraper 22 with a square cross-section against the right end of the sponge block 21, and the front and rear ends of the scraper 22 are pressed against the front and rear walls of the melt tank 11.
