[0038] Embodiment 2

[0039] Reference Figure 2, 7 As shown, on the basis of the first embodiment, the tensioning part 4 includes two tensioning rollers 401 supporting the film above and below, which are used to support the film and maintain the tension between the films, and are arranged on the front side of the hot pressing roller 103. The tensioning part 4 also includes two vertical guide frames 402, and two bearing seats 403 are slidably arranged in the vertical guide frames 402. The two ends of the tensioning roller 401 are respectively installed in the bearing seats 403 in the two vertical guide frames 402, and a contraction reset spring 404 is also installed between the two bearing seats 403 in the same vertical guide frame 402. The tensioning part 4 also includes a fine-tuning motor 407, and a moving frame 406 is installed on the output shaft of the fine-tuning motor 407. The two ends of the tensioning roller 401 are also rotatably installed with diagonal support rods 405, and the other ends of the diagonal support rods 405 are hingedly connected to the moving frame 406. In order to maintain stability during the sliding process of the moving frame 406, two cross rails 408 are also arranged in the chassis 5. The moving frame 40 6 is slidably mounted on two horizontal rails 408, and in order to facilitate observation of the tensioning of the film, a glass mask is also installed on the chassis 5 near the tensioning part 4, through which the tensioning of the film can be easily observed, and timely adjustment is convenient. When in use, the movable frame 406 can be pushed to slide by the fine-tuning motor 407, and when the movable frame 406 slides, it will push the diagonal support rod 405 thereon to slide. When the diagonal support rod 405 is opened, the tensioning roller 401 can be pushed to slide in the vertical guide frame 402, so as to facilitate changing the tensioning of the film. In addition, in order to facilitate the contraction and reset between the two tensioning rollers 401, a contraction reset spring 404 is also installed between the two bearing seats 403. When the movable frame 406 is away from the vertical guide frame 402, the angle between the two diagonal support rods 405 will be reduced. At this time, with the cooperation of the contraction reset spring 404, the two bearing seats 403 will be pulled close to each other and contracted.

[0040] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0041] The implementation principle of a winding device with a grid line film in an embodiment of the present invention is as follows: when working, the upper and lower films are first respectively assembled between the film conveying part 1, and the upper and lower films are kept being conveyed simultaneously, and then the winding drum 31 in the wire laying part 3 is started, and the winding drum 31 can continuously release the woven wire 32 when rotating, and through the cooperation of the horizontal wire laying mechanism and the longitudinal wire laying, the horizontal wire laying and the longitudinal wire laying can be laid on the corresponding film respectively, and the glue coating roller 33 can continuously contact the glue in the glue box 35 when rotating, so that the surface of the glue is covered with glue, and the woven wire 32 can be adhered to the glue coating roller 33 with the cooperation of the wire pressing roller 34, and then the glue coating roller 33 continues to rotate and contacts with the film, and the woven wire 32 can be adhered to the film, and after the upper and lower films are close to each other and pressed, the horizontal wire laying will form a grid line with the longitudinal wire laying, and while maintaining the strength of the film, it can be convenient to process and improve the processing efficiency, and it is simple and easy to construct. The pressed film will be directly wound on the winding drum 202 for packaging, which is convenient for transportation;

[0042] In order to ensure the laying of the grid lines, two wiring boxes 3102 are arranged in the longitudinal wiring mechanism. When the driving motor 3111 drives the turntable 3106 to rotate, while the wiring box 3102 slides, the slider 3105 installed at the eccentric position of the turntable 3106 will also slide in the corresponding guide groove 3104, so as to drive the swing rod 3103 to continuously expand and contract. At the same time, the slider 3105 at the bottom of the wiring box 3102 is also matched with the guide groove 3104 on the swing rod 3103, so that the wiring box 3102 can continuously slide back and forth in the wiring rack 3101, so that the weaving wires 32 can be laid on the film in a winding shape, and the weaving wires 32 in the transverse wiring mechanism are directly arranged in parallel in multiple lanes. The weaving wires 32 arranged in a winding shape can form grid lines after overlapping with multiple weaving wires 32 arranged in parallel in a straight line, which is convenient for increasing the strength of the film.

[0043] In order to maintain the tension between the films, the movable frame 406 can be pushed to slide by the fine-tuning motor 407. When the movable frame 406 slides, the diagonal support rod 405 thereon will be pushed to slide. When the diagonal support rod 405 is opened, the tensioning roller 401 can be pushed to slide in the vertical guide frame 402, so as to facilitate the change of the tensioning condition of the film. In order to facilitate the contraction and reset between the two tensioning rollers 401, a contraction and reset spring 404 is also installed between the two bearing seats 403. When the movable frame 406 moves away from the vertical guide frame 402, the angle between the two diagonal support rods 405 will be reduced. At this time, with the cooperation of the contraction and reset spring 404, the two bearing seats 403 will be pulled closer to each other and contracted, which is convenient for adjustment.
