Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing forming, in particular to a hot pressing forming device for waterproof and breathable films. Background Art

[0002] At present, waterproof and breathable films are needed in many fields to help with waterproofing and breathability, such as vehicle sunroofs, headlight interiors, etc., and are widely used. During the processing of waterproof and breathable films, a release film needs to be laminated, and then the corresponding specifications of shapes on the waterproof and breathable caps are formed by stamping and cutting with a mold.

[0003] Most of the existing hot pressing forming devices heat and roll the raw materials through hot pressing rollers. However, when the multi-layer laminating device for waterproof and breathable films is working, it is inconvenient to monitor the temperature of the hot pressing rollers. When the temperature of the hot pressing rollers is too low, the lamination effect of various raw materials is not good. When the temperature of the hot pressing rollers is too high, the raw materials are easily damaged by heat, and the melted raw materials are easily adhered to the hot pressing rollers, resulting in poor hot pressing effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hot pressing forming device for waterproof and breathable films to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] The arc hot pressing component is arranged inside the heat preservation box and is used for arc guiding of the preliminarily hot pressed raw material film. When the raw material film is arc-shaped conveyed, since there is a thickness difference between the inner side and the outer side of the raw material film, misalignment running-in will occur between the inner arc and the outer arc of the raw material film, thereby realizing secondary thermal fusion of the raw material film;

[0011] The guiding component is arranged on both sides of the arc hot pressing component and is used for guiding the raw material film.

[0014] As a further solution of the present utility model: A first spring sleeved on the fixed rod is arranged between the sliding cylinder and the inner wall of the heating box.

[0015] As a further solution of the present utility model: The arc-shaped hot pressing assembly includes a second fixed shaft fixedly connected to the inner wall of the heat preservation box, a fixed roller rotatably connected to the second fixed shaft, a hydraulic press fixedly connected to the outer wall of the heat preservation box, a lifting frame fixedly connected to the output shaft of the hydraulic press, piston cylinders fixedly connected to both sides of the lifting frame, a second spring installed inside the piston cylinder, a top block arranged on one side of the second spring, one end of a telescopic rod fixedly connected to the top block, the other end of the telescopic rod fixedly connected to a second mounting shaft, and a telescopic roller fixedly connected to the second mounting shaft, and the telescopic roller cooperates with the fixed roller.

[0016] As a further solution of the present utility model: The guiding assembly includes a first fixed shaft fixedly connected inside the heat preservation box, and a guiding roller rotatably connected to the first fixed shaft.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the heat drying lamps, the heat-sealing side of the raw material film is heated and melted, then the raw material film is hot-pressed by the preliminary hot pressing assembly, and then through the cooperation of multiple groups of arc-shaped hot pressing assemblies, the two groups of raw material films are misaligned and ground in, thereby realizing the secondary hot pressing and fusion of the raw material film, improving the hot melting effect of the equipment and the product quality.

[0025] Refer to Figures 1 to 5 , in the embodiments of the present utility model, a hot pressing and forming device for a waterproof and breathable film includes a heat preservation box 1, a heating box 2, a heat drying assembly, a preliminary hot pressing assembly, an arc hot pressing assembly, and a guiding assembly; the heating box 2 is connected to the heat preservation box 1, two sets of symmetrically arranged feed ports 4 are arranged on the side of the heating box 2 away from the heat preservation box 1, and a discharge port 3 is arranged on the side of the heat preservation box 1 away from the heating box 2; the heat drying assembly is arranged inside the heating box 2 near the feed port 4; the preliminary hot pressing assembly is arranged inside the heating box 2 away from the feed port 4; the arc hot pressing assembly is arranged inside the heat preservation box 1; the guiding assembly is arranged on both sides of the arc hot pressing assembly for guiding the raw material film. First, the present utility model heats multiple groups of raw material films through the heat drying assembly, then preliminarily thermally fuses the heat-dried raw material films through the preliminary hot pressing assembly, and then conveys them inside the heat preservation box 1 through the guiding assembly. During the conveying process, the arc hot pressing assembly performs arc guiding on the preliminarily hot-pressed raw material film. When the raw material film is arc-shaped conveyed, there will be a thickness difference between the inner side and the outer side of the raw material film, so that the inner and outer arcs of the raw material film will produce misaligned running-in, thereby realizing the secondary thermal pressing and fusing of the raw material film.

[0026] In one case of this embodiment, please refer to Figures 1 to 5 , the heat drying assembly includes a mounting rack 5 fixedly connected inside the heating box 2, and multiple groups of misaligned heat drying lamps 6 are fixedly connected to the mounting rack 5. The heat drying assembly uniformly heats the raw material film through multiple groups of misaligned heat drying lamps 6.

[0027] In one case of this embodiment, please refer to Figures 1 to 5 , the preliminary hot pressing assembly includes a fixed rod 7 fixedly connected inside the heating box 2. Two sets of symmetrically arranged sliding cylinders 8 are slidably connected to the fixed rod 7. A first mounting shaft 9 is fixedly connected to the sliding cylinder 8. A hot pressing roller 10 is rotatably connected to the first mounting shaft 9. A first spring 11 sleeved on the fixed rod 7 is arranged between the sliding cylinder 8 and the inner wall of the heating box 2. The preliminary hot pressing assembly elastically pushes the sliding cylinder 8 through the arrangement of the first spring 11. The sliding cylinder 8 drives the two first mounting shafts 9 to move towards each other. The first mounting shafts 9 drive the two hot pressing rollers 10 to close in, and then hot pressing is performed through the two hot pressing rollers 10.

[0028] In one case of this embodiment, please refer to Figures 1 to 5 , the arc-shaped hot pressing assembly includes a second fixed shaft 22 fixedly connected to the inner wall of the heat preservation box 1. A fixed roller 23 is rotatably connected to the second fixed shaft 22. A hydraulic press 14 is fixedly connected to the outer wall of the heat preservation box 1.

The other end of the telescopic rod 19 is fixedly connected to a second mounting shaft 20. A telescopic roller 21 is fixedly connected to the second mounting shaft 20. The telescopic roller 21 cooperates with the fixed roller 23. Through the arrangement of the fixed roller 23 in the arc-shaped hot pressing assembly, the preliminarily hot-pressed raw material film is attached to the surface of the roller. At this time, there is a thickness difference between the inner and outer sides of the raw material film. Therefore, when the inner and outer sides of the raw material film move horizontally to the surface of the fixed roller 23, relative sliding will occur between the inner and outer sides of the raw material film. And during this process, the second spring 18 is used to push the top block 17. The top block 17 drives the second mounting shaft 20 to be elastically pushed out through the telescopic rod 19. The second mounting shaft 20 drives the telescopic roller 21 to press towards the fixed roller 23, thereby realizing the grinding and pressing of the raw material film, and thus realizing the secondary hot pressing and fusion of the raw material film.

[0029] In one case of this embodiment, please refer to Figures 1 to 5 , the guiding assembly includes a first fixed shaft 12 fixedly connected inside the heat preservation box 1. A guiding roller 13 is rotatably connected to the first fixed shaft 12. The guiding assembly performs rolling positioning installation on the guiding shaft through the arrangement of the first fixed shaft 12, and guides the raw material film through the guiding roller 13, thereby positioning the feeding and discharging directions of the raw material film.
