Description

Technical Field

[0001] This utility model relates to membrane processing equipment, and in particular to the membrane frame structure of polymer molding film for automotive seat dust covers. Background Technology

[0002] Car seat dust covers are used for dust prevention in car seats. Existing car seat dust covers use a two-layer plastic film structure with hot-pressed edges. During the forming or lamination hot-pressing process of existing car seat dust cover films, the film needs to be stretched and rolled up. However, due to factors such as static electricity and wind speed during the film collection process, existing processing equipment may result in insufficient tension of the collected material, leading to cumbersome processing in the next step or problems with the edge joining of specific shaped laminations. Utility Model Content

[0003] The purpose of this invention is to provide a film-forming frame structure for a polymer molded film for automotive seat dust covers, solving the problem of misalignment at the edges of ordinary double-layer molded films during winding.

[0005] The pneumatic gap mold clamping and pressing structure includes a hot-pressing connecting seat connected to a connecting platform inside the movable mold clamping seat, and a pressing block located at the outer end of the hot-pressing connecting seat.

[0006] The guide seat structure includes a material conveying platform, and the inner guide roller group structure includes a central guide roller body disposed in the material conveying platform, a set of material conveying adjustment roller structures disposed outside the central guide roller body in the material conveying platform, and a material conveying limiting roller disposed outside the material conveying adjustment roller structures.

[0018] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1, as Figure 1-6 As shown, the film-forming frame structure of the polymer molded film for automotive seat dust covers includes a set of spaced-apart transmission guide frames and a film edge-forming structure located between the two transmission guide frames. Two sets of docking connectors 15 are provided on the outer side of the film edge-forming structure and connected to the two transmission guide frames. The outer side of the transmission guide frame at the feeding end is connected to the feeding roller 16, and the outer side of the transmission guide frame at the discharging end is connected to the receiving roller 17. The two layers of film in the feeding roller 16 are joined and molded through a pneumatic gap-fitting edge-pressing structure within the film edge-forming structure, allowing for preliminary edge-fitting of the two layers. This ensures accurate alignment of the two layers of film and improves the efficiency of the molding and edge-forming process during the subsequent edge heat-sealing process.
