Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0021] The utility model discloses a double-sided film laminating device for plastic woven bags, which is mainly used in the production of plastic woven bags.

[0022] Reference Figure 1 and Figure 2 A double-sided film coating equipment for plastic woven bags comprises: a placing table 1, a pillar 2 is equidistantly fixedly connected to the bottom of the placing table 1, a first fixed block 3 is equidistantly fixedly connected to the top of the placing table 1, a feeding roller 4 is rotatably connected between one side of the first fixed block 3, a first motor 12 is arranged on one side of the first fixed block 3, a second fixed block 5 is equidistantly fixedly connected to the top of the placing table 1, a winding roller 6 is rotatably connected between one side of the second fixed block 5, a second motor 24 is arranged on one side of the second fixed block 5, two connecting plates 7 are fixedly connected to the top of the placing table 1, a first coating roller 17, a second coating roller 18 and a guide roller 10 are rotatably connected between one side of the two connecting plates 7, a heating component is arranged on one side of the connecting plate 7, a pressing component is arranged on the top of the connecting plate 7, and a cooling component is arranged on the other side of the connecting plate 7.

[0023] In the above technical scheme, considering the problem that the coating is not smooth when the woven bag is coated, in order to solve such problem, the specific operation is as follows: the woven bag is passed through the heating component and heated to facilitate the plastic film to be firmly bonded to the surface of the woven bag later, and then passed between the first coating roller 17 and the pressing component. The pressing component will press to ensure the flatness of the woven bag later and prevent the woven bag from wrinkling. The first coating roller 17 will coat the bottom of the woven bag, and then pass through the bottom of the second coating roller 18 and coat the top thereof, thereby achieving double-sided coating of the woven bag, and then pass through the top of the guide roller 10 and enter the cooling component for cooling to ensure that the film solidifies quickly, which helps to ensure that the film is firmly bonded to the woven bag and improve production efficiency and product quality, and finally pass through the bottom of the winding roller 6 for winding.

[0024] Reference Figure 3 and Figure 4 In a preferred embodiment, the pressing assembly includes a mounting plate 13, the mounting plate 13 is fixedly connected to the top of the connecting plate 7, the bottom of the mounting plate 13 is equidistantly fixedly connected with a connecting block 19, the bottom of the connecting block 19 is provided with a mounting block 22, one side of the mounting block 22 is rotatably connected with a pressing roller 25, the bottom of the connecting block 19 is provided with a slide groove 20, the top of the mounting block 22 extends to the top of the slide groove 20 and is fixedly connected to a limiting block 21, and a spring 23 is provided between the top of the limiting block 21 and the top of the inner wall of the slide groove 20;

[0025] In the above technical scheme, it is taken into consideration that when the woven bag is coated, the coating is prone to be uneven, which may cause wrinkles in the film. In order to solve such problems, the specific operations are as follows: by utilizing the tension of the spring 23 inside the connecting block 19, the limit block 21 is always kept downward, thereby driving the mounting block 22 to remain downward, so that the pressing roller 25 can always be in contact with the plastic bag, allowing it to remain flat and avoid wrinkles in the plastic bag.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, the heating assembly includes an upper electric heating plate 8, which is arranged between one side of the connecting plate 7, and a lower electric heating plate 9 is arranged on one side of the connecting plate 7 and at the bottom of the upper electric heating plate 8; the woven bag is passed through the middle of the upper electric heating plate 8 and the lower electric heating plate 9, and the heating of the woven bag is started, so that the plastic film can be firmly bonded to the surface of the woven bag to form a sealed layer, thereby effectively improving the waterproof performance of the bag.

[0027] Reference Figure 2 and Figure 3In a preferred embodiment, the cooling assembly includes a shell 14, which is fixedly connected to one side of the connecting plate 7. The top and bottom of the shell 14 are provided with through grooves 11, and the interior of the shell 14 is provided with a receiving groove 16. Fans 15 are fixedly installed on both sides of the shell 14. By setting the shell 14, the plastic bag is passed through the through groove 11, and the fan 15 can be used to supply air inside to cool the plastic bag. During the laminating process, the plastic film needs to be cooled quickly after being heated to ensure that the film solidifies quickly. The fan 15 can accelerate the heat dissipation of the film surface, so that it can be cooled quickly, which helps to improve production efficiency. The shell 14 can reduce the loss of wind and improve the cooling efficiency.

[0028] Reference Figure 3 and Figure 4 In a preferred embodiment, one end of the first laminating roller 17 is staggered with one side of the connecting block 19; by staggering the first laminating roller 17 and the connecting block 19, it is possible to avoid contact between the first laminating roller 17 and the connecting block 19, thereby preventing the first laminating roller 17 from rotating to laminar the plastic bag.

[0029] Working principle: When in use, let the woven bag pass through the middle of the upper electric heating plate 8 and the lower electric heating plate 9, and start heating the woven bag, so as to facilitate the plastic film to be firmly bonded to the surface of the woven bag later, and then pass through between the first coating roller 17 and the pressing roller 25. Under the action of the spring 23, the pressing roller 25 will always keep in contact with the woven bag to ensure the flatness of the woven bag later and prevent the woven bag from wrinkling. The first coating roller 17 will coat the bottom of the woven bag, and then pass through the bottom of the second coating roller 18 and coat the top of it. One end of the first coating roller 17 and the second coating roller 18 are both provided with a driving motor, so as to realize double-sided coating of the woven bag, and then pass through the top of the guide roller 10 and enter the shell 14, and start the fan 15 to deliver wind inside the shell 14 to cool the woven bag to ensure that the film is quickly solidified and cured, which helps to ensure that the film is firmly bonded to the woven bag, and finally pass through the bottom of the winding roller 6 for winding.
