Specific implementation mode

[0022] The following further describes in detail the implementation mode of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figure 1 and Figure 4 shown, a flat-laying mechanism for an EVA film layer includes a machine base 1. A cleaning cavity 2 is provided at the left end inside the machine base 1. An inner guide wheel 7 is rotatably connected to the upper right end of the cleaning cavity 2. A first scraper 8 is arranged on the left side of the inner guide wheel 7. A blanking box 9 is slidably connected to the lower left end of the inner guide wheel 7 inside the machine base 1. A support 6 is fixedly connected to the middle part of the upper side of the machine base 1. A connecting shaft 14 penetrates through the middle part of the upper end of the support 6. An outer guide wheel 10 is rotatably connected to the upper end of the support 6 through the connecting shaft 14. An outer housing 11 is fixedly connected to the lower end of the support 6 where the outer guide wheel 10 is located. A second scraper 13 is fixedly connected to the left end inside the outer housing 11. An inner housing 12 is rotatably connected to the inside of the outer housing 11 through the connecting shaft 14. The inner housing 12 and the outer housing 11 are in a hollow semi-circular shape. The internal structure size of the inner housing 12 is matched with the external structure size of the outer guide wheel 10. The inner housing 12 inside the outer housing 11 can rotate through the connecting shaft 14, and then cover and store the outer guide wheel 10 when the whole device is not in use, thereby reducing the adhesion of external dust and other impurities, and avoiding adhering impurities to the film layer during subsequent guiding and driving of the film layer, which affects the production effect. Connecting buckles are sleeved at the front and rear ends of the connecting shaft 14, and the connecting shaft 14 is snap-connected with the support 6. A second scraper 13 is integrally arranged inside the outer housing 11, so that during operation, the impurities adhered to the surface of the outer guide wheel 10 can be scraped and cleaned by the second scraper 13, reducing the influence. At the same time, the connecting buckles sleeved on the outer sides of the front and rear ends of the connecting shaft 14 snap-limit the connecting shaft 14 with the support 6. Correspondingly, by removing the connecting buckles, the connecting shaft 14 can be pulled out, and then it is convenient to disassemble the inner housing 12 connected by the connecting shaft 14, so as to centrally clean the impurities collected inside the inner housing 12. A combing wheel 16 is arranged at the right end of the upper side of the machine base 1, and a protective cover 15 is connected to the outer end of the combing wheel 16.

[0024] As Figure 1 and Figure 2 shown, a mounting seat 3 is fixedly connected to the middle of the rear end of the cleaning chamber 2. A connecting seat 4 is slidably connected to the front end of the mounting seat 3. A blower 5 is installed at the front end of the connecting seat 4. The connecting seat 4 can slide left and right along the sliding track on the surface of the mounting seat 3, so as to adjust the position of the blower 5 and blow and clean the EVA film layer passing through the inside of the cleaning chamber 2 at multiple positions, thereby eliminating the influence of impurities that may adhere to the surface of the film layer.

[0025] As Figure 1 and Figure 3 shown, limiting rails 17 are fixedly connected to the front and rear ends outside the carding wheels 16 on the upper side of the machine base 1. Mounting grooves 18 are opened at the front and rear ends inside the protective cover 15. The protective cover 15 is snap-connected to the limiting rails 17 through the mounting grooves 18. The mounting grooves 18 are L-shaped. The protective cover 15 is snap-connected and docked with the limiting rails 17 through the L-shaped mounting grooves 18 inside to realize the limiting installation of the protective cover 15, which can ensure the protection of multiple groups of carding wheels 16 inside, and is also convenient for disassembly, facilitating the maintenance and repair of the carding wheels 16 inside.

[0026] In summary, as Figures 1 to 4 shown, for this EVA film layer laying mechanism, during use, first, the film layer passes through the cleaning chamber 2 at the front end of the machine base 1 and is initially blown by the blower 5 installed at the front end of the connecting seat 4 to clean dust and other impurities that may adhere to its surface. Subsequently, it is guided and conveyed through the inner guide wheel 7 at the right end outlet of the cleaning chamber 2 and the outer guide wheel 10 at the upper end of the support 6. During this process, the inner guide wheel 7 and the outer guide wheel 10 rotate continuously, and a first scraping plate 8 and a second scraping plate 13 are arranged at their outer ends to scrape and clean their outer surfaces, eliminating the impurities adhering to the surface. The scraped dust falls into the material receiving box 9 and the inner housing 12 respectively for centralized collection and cleaning, and then passes through the carding wheels 16 for laying, processing and winding. Correspondingly, after the whole processing is completed, when processing is not required for a short time, the inner housing 12 is flipped and covered through the connecting shaft 14 to close and protect the outer guide wheel 10. At the same time, the carding wheels 16 are protected by the protective cover 15 on the outside, reducing the interference of normal dust and floating objects. In this way, the use process of the entire EVA film layer laying mechanism is completed.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.
