Description

Technical Field

[0001] The utility model relates to the technical field of polyimide films, in particular to a slitting device for processing polyimide film finished products. Background Art

[0002] Polyimide film is one of the earliest commercial polyimide products, used for slot insulation in motors and cable wrapping. Key products include DuPont Kapton, Ube Industries' Upilex series, and Kaneka Apical. Transparent polyimide film can be used as a flexible substrate for solar cells. IKAROS sails are made using polyimide film and fiber. Polyimide fiber can be used for hot gas filtration, while polyimide yarn can separate dust and special chemicals from exhaust gas.

[0003] Among the existing polyimide film slitting equipment, most designs only focus on the cutting function itself and lack comprehensive consideration of the entire operation process. Taking the utility model with patent number CN220113402U as an example, although the device has basic cutting capabilities, it is not equipped with corresponding auxiliary facilities. The shortcoming of this design is that when the cutting operation is carried out, because the polyimide film material is extremely soft, it often leads to uneven cuts and uneven quality. In addition, this slitting device also has certain inconveniences during operation. Whenever the film needs to be cut, the operator must manually stop the operation of the equipment before the cutting operation can be carried out. This not only increases the complexity of the operation, but also reduces work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a slitting device for processing polyimide film finished products to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a slitting device for processing polyimide film finished products, comprising a base, grooves on both sides of the base, a threaded rod in each groove, a motor at the end of each threaded rod, a reinforcing block sleeved on each threaded rod, a column fixed on the side of the reinforcing block, a plurality of first fixed plates fixed on both sides of the column, an electric telescopic rod on each first fixed plate, a splint fixed on the output end of the electric telescopic rod, a group of slide grooves at both ends of the splint, a guide rail in each group of slide grooves, each guide rail fixed on a second fixed plate, a limit block fixed at both ends of each second fixed plate, the polyimide film is placed between the plurality of splints, and the electric telescopic rod pushes the plurality of splints close to each other to clamp the polyimide film.

[0006] As a preferred embodiment of the present invention, a first through hole is formed at one end of the groove close to the motor, and a limiting ring is provided in the first through hole. The first through hole is used to insert the threaded rod, and the limiting ring prevents the threaded rod from escaping from the inside of the groove.

[0007] As a preferred embodiment of the present invention, a second through hole is provided on the reinforcing block and the column, and the second through hole is connected to the threaded rod by a threaded connection. The second through hole is used to insert the threaded rod, and the threaded connection facilitates the threaded rod to push the reinforcing block and the column to move.

[0008] As a preferred embodiment of the present invention, a cutting device body is provided on the column, and a triangular block is fixed on the cutting device body. The triangular block is used to push the cut polyimide film to both sides to prevent the cutting device from scratching the film.

[0009] As a preferred embodiment of the present invention, a plurality of conveying rollers are provided on the base for conveying the polyimide film.

[0010] As a preferred embodiment of the present invention, a controller is provided on one side of the base, and an operation screen is provided on the controller. The controller can be set through the operation screen to control the cutting frequency of the device.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model achieves the purpose of neatly cutting the polyimide film through the clamping plates, the threaded rod and the motor, and the threaded rod pushes the cutting device body to keep moving synchronously with the polyimide film for cutting, avoiding the need to stop the device during cutting. At the same time, the plurality of clamping plates clamp the film, avoiding uneven incisions caused by the film being too soft after the cutting starts. BRIEF DESCRIPTION OF THE DRAWINGS
