Description

Technical Field

[0001] The utility model relates to the technical field of film production equipment, in particular to a film production equipment which is convenient for replacing the forming part. Background Art

[0002] Polycarbonate itself has good mechanical tensile properties, scratch resistance, etc., and is mainly applied to the surface of suitcases. At present, most of the polycarbonate films on the market have simple texture structures. Adding 3D textures to the surface of the polycarbonate film can make the product surface more vivid, and the effects presented when observing the product from different angles are different, showing a good visual effect.

[0003] For example, Chinese Patent CN216860371U proposes a pressing and forming roller for wavy films, which includes a cooling roller shaft. A ceramic tube body is arranged on the outer peripheral surface of the cooling roller shaft. A wavy texture layer is arranged on the outer peripheral surface of the ceramic tube body, and an anti-adhesive layer is arranged on the wavy texture layer. Thus, the pressing and forming requirements of the wavy film are met. The ceramic tube body is used for forming the wavy texture layer, eliminating the risk of direct processing on the cooling roller shaft and preventing the cooling roller shaft from being scrapped.

[0004] The above patent uses a ceramic tube body to protect the cooling roller, but ceramics have defects such as being fragile and having poor thermal conductivity, and the damage rate is relatively high in actual use.

[0005] Based on this, the utility model designs a film production equipment which is convenient for replacing the forming part to solve the above problems. Summary of the Utility Model

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a film production equipment which is convenient for replacing the forming part.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0008] A film production equipment which is convenient for replacing the forming part, including an extrusion head;

[0009] The extrusion head is fixedly connected to an external frame, and a texture roller, a first cooling roller and a second cooling roller are rotatably connected to the external frame in sequence from left to right;

[0010] The texture roller includes a nickel plating layer, a copper plating layer and a roller blank. The outer layer of the roller blank is plated with a copper plating layer, and the outer layer of the copper plating layer is plated with a nickel plating layer. Wave patterns are engraved on the surface of the nickel plating layer.

[0011] Furthermore, the PC film is extruded from the discharge end of the extrusion head.

[0012] Further, the PC film bypasses the gap between the nickel plating layer and the first cooling roller, passes under the first cooling roller, and then passes above the second cooling roller, and is wound on an external winding roller.

[0013] Further, the copper plating layer is finely processed and has a smooth and flat surface.

[0014] Further, multiple groups of cooling pipelines are provided inside the first cooling roller and the second cooling roller.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] When the PC film is extruded from the discharge end of the extrusion head, it bypasses the gap between the nickel plating layer and the first cooling roller, passes under the first cooling roller, and then passes above the second cooling roller, and is wound on an external winding roller; when the PC film passes through the nickel plating layer, the texture on the surface of the nickel plating layer is transferred to the surface of the PC film. By adjusting parameters such as the temperature and rotation speed of the roller blank, the first cooling roller, and the second cooling roller, the texture effect of the PC film is adjusted, making the surface of the product more vivid and presenting different effects when observed from different angles, showing a good visual effect; when it is necessary to replace the forming part of the PC film, after the PC film is extruded from the discharge end of the extrusion head, it bypasses above the first cooling roller, the gap between the first cooling roller and the second cooling roller, and then passes under the second cooling roller, and is wound on an external winding roller. At this time, the PC film does not contact the nickel plating layer, and no texture will be printed on the PC film, thus achieving the effect of replacing the forming part of the PC film; the copper plating layer and the nickel plating layer on the outer layer of the roller blank are hard and not easily broken, with a low damage rate in actual use, so the maintenance cost is reduced, and the copper plating layer and the nickel plating layer have good heat conduction performance.
