Description

Technical Field

[0001] The utility model belongs to the technical field of polyimide film production, and specifically refers to a polyimide film winding tension adjusting device. Background Technique

[0002] As is well known, a polyimide film is a film product generated after a series of process treatments such as solution casting, stretching, and high-temperature imidization. It is widely used in fields such as aviation, mobile phones, and displays. After the polyimide film is processed, it needs to be wound for convenient storage and transportation. The existing winding work is mainly directly wound by a rotating winding roller. However, due to the ductility of the film itself, the film is prone to offset or wrinkle during winding, resulting in the inability to perform normal winding work and affecting the winding quality of the film.

[0003] In the prior art, a Chinese patent with the publication number CN217172680U discloses a polyimide film winding tension adjusting device. The winding roller is driven to rotate by an external motor, and the arcuate fixed groove plate is fixed by an external fixing frame. When the winding roller rotates and winds the film, the winding roller pulls the film to convey and makes the film continuously wound around the winding roller. At this time, the film drives two first tensioning rollers to rotate synchronously. The elastic pushing mechanism pushes the two first tensioning rollers away from each other through the first mounting plate. The two first tensioning rollers generate an outward tension on the film in the conveying state, so that the film is in a taut state. When the first tensioning roller moves, the first tensioning roller drives the slider to slide on the guide rail through the first mounting plate. By generating tension on the film in the conveying state, it is convenient to keep the film in a taut state all the time, facilitate the flat conveying and winding of the film around the winding roller, improve the neatness of the film wound by the winding roller, avoid the phenomenon of offset or wrinkle during film winding and affecting the winding quality, and improve the practicability.

[0004] However, the above prior art cannot adjust the tension degree according to the use needs and does not set a buffer structure. Summary of the Utility Model

The tension adjusting assembly includes a transmission adjusting assembly and a buffer assembly. The transmission adjusting assembly is arranged on the side of the workbench, and the buffer assembly is installed on the transmission adjusting assembly.

[0008] Further, the transmission adjusting assembly includes a transmission motor, a mounting seat, a threaded rod, a nut slider, and a traction frame. The transmission motor and the mounting seat are respectively arranged at both ends of the workbench. One end of the threaded rod is fixedly arranged on the output shaft of the transmission motor, and the other end is rotatably connected to the mounting seat. The nut slider is threadedly connected to the threaded rod and slides relative to the workbench. The traction frame is fixedly arranged on the nut slider, and a traction groove is formed on the traction frame.
