Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a double glue leveling mechanism for a gravure head of a coating machine. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. This machine coats a roll of base material with a glue, coating, ink, etc. with specific functions, and after drying, it is cut into pieces or wound up. When the existing coating machine coats glue on the film, it only has the function of coating the glue on the film, and cannot make the glue coated on the film uniform. Therefore, after the glue coating is completed, there are the following problems. It is very difficult to control the amount of glue applied. If too much glue is applied, the glue will overflow, not only wasting the glue but also contaminating the product surface, resulting in unqualified appearance of the finished product; if too little glue is applied, the sealing performance of the product cannot be guaranteed. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: in order to overcome the problem that when the existing coating machine coats glue on the film, it only has the function of coating the glue on the film and cannot make the glue coated on the film uniform, a double glue leveling mechanism for a gravure head of a coating machine is provided.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a double glue leveling mechanism for a gravure head of a coating machine, comprising:

[0005] A glue coating mechanism, which is used to coat glue on one side of the product and send the product to the glue scraping mechanism after the product is coated with glue;

[0006] A glue scraping mechanism, which is used to scrape off the excess glue on the surface of the product passing through the glue coating mechanism. The input end of the glue scraping mechanism is docked with the output end of the glue coating mechanism. The glue scraping mechanism comprises a glue scraping base, a mounting seat, a glue scraping roller, a driving member and a glue scraping transition roller. The mounting seat is slidably connected with the glue scraping base. The driving member is fixedly connected with the glue scraping base.

The glue scraping transition roller is rotatably connected with the glue scraping base;

[0007] And a glue spreading mechanism, which is used to level the glue on the surface of the product output from the glue scraping mechanism. Through the design of the glue scraping mechanism and the glue spreading mechanism, it can scrape off the excess glue liquid and evenly spread the remaining glue liquid on the film, thereby improving the bonding quality of the film.

[0008] In order to solve the problem that it is inconvenient to apply the glue liquid by the glue coating mechanism, the glue coating mechanism further comprises a pressure roller, a glue coating roller and a glue coating groove. The glue coating groove is used to hold the glue liquid. The glue coating roller is in contact with the glue liquid in the glue coating groove. The pressure roller is located above the glue coating roller. A gap for the product to pass through is left between the pressure roller and the glue coating roller.

[0009] To solve the problems of inability to control the contact degree between the film and the coating roller and the small adjustment range of the contact degree, it further includes that a through hole for the coating transition roller to move is formed on the coating base, and the roller ends of the coating transition roller are installed in the through hole.

[0010] To solve the problem of insufficient stability of the coating roller during the working process, it further includes that the mounting seat is slidably connected to the coating base. A slide rail is formed on the coating base, and the mounting seat has a chute matching the slide rail. The slide rail is slidably arranged in the chute, and the mounting seat is slidably connected to the slide rail.

[0011] To solve the problem that it is necessary to stop the machine for cleaning after one coating groove is full, it further includes that two coating grooves are formed on the coating roller, and the two coating grooves are arranged oppositely;

[0012] When the notch of one of the coating grooves faces upward, the notch of the other coating groove faces downward.

[0013] It further includes that the glue spreading mechanism includes a glue spreading base, a glue spreading roller and a glue spreading transition roller. The glue spreading roller is rotatably connected to the glue spreading base, the glue spreading transition roller is rotatably connected to the glue spreading base, and the glue spreading roller is located between the glue spreading transition roller and the coating transition roller.

[0014] The beneficial effects of the present utility model are as follows: A double glue leveling mechanism for the anilox roll of a coater provided by the present utility model can scrape off the excess glue and level the remaining glue on the film through the designs of the coating mechanism and the glue spreading mechanism, thereby improving the bonding quality of the film.

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] like Figure 1 It is a structural schematic diagram of the utility model, a double glue-smoothing mechanism of a coating machine anilox head. The double glue-smoothing mechanism of the present application is mainly used in the production of PE film, including:

[0024] like Figure 1 , Figure 3 As shown, the gluing mechanism 1 is used to apply glue to one side of the product and send the product to the gluing mechanism 2 after the product is glued;

[0025] The glue coating mechanism 1 includes a pressure roller 11, a glue coating roller 12 and a glue coating groove 13. The glue coating groove 13 is used to scrape off excess glue and accommodate glue. The glue coating roller 12 is in contact with the glue in the glue coating groove 13. The glue coating roller 12 is rotatably connected to the frame of the coating machine. In the process of the PE film passing through the glue coating roller 12, the PE film and the glue coating roller 12 are in contact, so that the glue is smeared on the PE film. The pressure roller 11 is located above the glue coating roller 12. The pressure roller 11 makes the PE film and the glue coating roller 12 contact. A gap is left between the pressure roller 11 and the glue coating roller 12 for the product to pass through. The pressure roller 11 is rotatably connected to the frame of the coating machine.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the scraping mechanism 2 is used to scrape off excess glue on the surface of the product passing through the glue coating mechanism 1. The input end of the scraping mechanism 2 is connected to the output end of the glue coating mechanism 1. The scraping mechanism 2 includes a scraping base 21, a mounting seat 22, a scraping roller 23, a driving member 24 and a scraping transition roller 25.

[0027] The mounting seat 22 is slidably connected to the scraper base 21, and the mounting seat 22 is slidably connected to the scraper base 21. The scraper base 21 is provided with a slide rail 26, and the mounting seat 22 has a slide groove matching the slide rail 26. The slide rail 26 is slidably arranged in the slide groove. The mounting seat 22 is slidably connected to the slide rail 26. The design of the slide rail 26 and the slide groove on the mounting seat 22 can increase the stability of the mounting seat 22 when the mounting seat 22 moves relative to the scraper base 21. The driving member 24 is fixedly connected to the scraper base 21, and the output end of the driving member 24 is transmission-connected to the mounting seat 22. The driving member 24 is used to provide power for the movement of the scraper roller 23. The driving member 24 can be a power component such as a hydraulic cylinder or a cylinder.

[0028] The glue scraping roller 23 is arranged on the mounting seat 22. At least one glue scraping groove 231 is formed on the outer peripheral surface of the glue scraping roller 23. Two glue scraping grooves 231 are formed on the glue scraping roller 23, and the two glue scraping grooves 231 are arranged oppositely. The number of the glue scraping grooves 231 can also be three or more. The present application does not make specific limitations on the number of the glue scraping grooves 231;

[0029] When the notch of one of the glue scraping grooves 231 faces upward, the notch of the other glue scraping groove 231 faces downward, so that during the operation of the glue scraping mechanism 2, the cleaning of the idle glue scraping groove 231 is completed, thereby improving the work efficiency.

[0030] The glue scraping transition roller 25 is rotatably connected to the glue scraping base 21. A through hole 211 for the movement of the glue scraping transition roller 25 is formed on the glue scraping base 21. The roller end of the glue scraping transition roller 25 is installed in the through hole 211. The glue scraping transition roller 25 is rotatably arranged on the connecting shaft. The connecting shaft and the through hole are detachably fixed. The connecting shaft is installed at the through hole through a threaded connector. When the position of the glue scraping transition roller 25 needs to be adjusted, the fixing of the connecting shaft is loosened, so that the glue scraping transition roller 25 can freely move along the through hole 211.

[0031] Such as Figure 1 、 Figure 3 As shown in the figure, the glue spreading mechanism 3 is used to level the glue on the surface of the product output from the glue scraping mechanism 2.

[0032] The glue spreading mechanism 3 includes a glue spreading base 31, a glue spreading roller 32 and a glue spreading transition roller 33. The glue spreading roller 32 is rotatably connected to the glue spreading base 31. The glue spreading transition roller 33 is rotatably connected to the glue spreading base 31. The glue spreading roller 32 is located between the glue spreading transition roller 33 and the glue scraping transition roller 25. By controlling the relative positions of the glue spreading roller 32 and the glue spreading transition roller 33, the contact degree between the PE film and the glue spreading roller 32 is controlled, so as to control the amount of glue liquid on the film after leveling.

[0033] During use, the PE film passes through the glue coating mechanism 1, the glue scraping mechanism 2 and the glue spreading mechanism 3 in sequence and then enters the next process.

[0034] The PE film to be coated with glue first passes through the gap between the pressure roller 11 and the glue coating roller 12 of the glue coating mechanism 1, so that the glue coating roller 12 contacts the PE film to complete the coating of the glue liquid;

[0035] Secondly, it passes through the glue scraping roller 23 of the glue scraping mechanism 2, and the PE film contacts the notch of the glue scraping groove 231, so that the excess glue liquid is scraped off. Then it passes through the glue scraping transition roller 25. By controlling the relative positions of the glue scraping transition roller 25 and the glue scraping roller 23, the contact degree between the PE film and the glue scraping roller 23 is controlled, so as to control the amount of the scraped glue liquid.

[0036] Again, through the glue spreading roller 32 and the glue spreading transition roller 33 of the glue spreading mechanism 3, the glue spreading roller 32 levels the remaining glue on the PE film, completing the coating of the glue on the PE film.

[0037] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
