Technical Field

[0001] The utility model relates to the field of film edge trimming, in particular to a film edge trimming device. Background Art

[0002] During the production and processing of films, it is often necessary to use a trimming device to perform trimming work according to the required size. Patent document: CN 218428765 U proposes a film trimming device, which can adjust the longitudinal position of the cutter according to PC films of different thicknesses, and can adjust the lateral position of the cutter according to PC films of different widths. The problem with this technical solution is that most of the above-mentioned existing film trimming devices lack protective components. During the adjustment process of the film or the trimming component, the two are easy to contact, resulting in miscutting. In addition, the staff are also easily injured by the trimming component during the operation of the workbench, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: the above-mentioned existing film trimming devices mostly lack protective components, and the film or the trimming component are easily contacted during adjustment, resulting in miscutting, and the staff are also easily injured by the trimming component during operation at the workbench, which is inconvenient to use.

[0004] In order to solve the problems existing in the prior art, the utility model provides a film trimming device, including a cutting rail, a cutting guide block and a protective cover, the cutting rail is provided with a cutting guide block on the periphery, the cutting guide block is provided with an adjustment seat at the bottom, a motor is provided on one side of the adjustment seat, electric guide rails are provided on both sides of the protective cover, a slider is provided on the periphery of the electric guide rail, and a blade is provided at the bottom of the slider.

[0005] Furthermore, a rotating rod is provided between the adjustment seats on the other side of the motor, and the top of the protective cover is connected to the rotating rod through a connecting rod. The motor is started to drive the rotating rod to rotate, and the connecting rod and the protective cover are driven to rotate by the rotation of the rotating rod, thereby completing the angle adjustment work.

[0006] Furthermore, a photoelectric sensor is provided at one end of the protective cover, and the photoelectric sensor is electrically connected to the electric guide rail. When the single film trimming is completed and the photoelectric sensor detects that there is no film below, the electric guide rail starts to drive the slider and the blade to rise after receiving the signal, and the blade is stored in the protective cover.

[0007] Furthermore, the bottom of the protective cover is hollowed out, and the protective cover is made of a transparent material, which makes it convenient for staff to observe the blade inside.

[0008] Furthermore, the top of the blade is connected to the slide block via a connecting seat and a connecting bolt, and the connecting bolt and the connecting seat are disassembled and assembled to facilitate the staff to disassemble and replace blades of different models and specifications.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model allows a worker to adjust the blade to descend and extend it out of the protective cover, and to complete the film trimming work by means of the cutting guide block sliding horizontally on the cutting rail. When the trimming of a single film is completed and the photoelectric sensor detects that there is no film underneath, the electric guide rail drives the slider and the blade to rise, and the blade is stored in the protective cover, thereby avoiding miscutting or accidental injury to the worker. When the trimming work is completed, the worker can drive the rotating rod to rotate by starting the motor, and drive the connecting rod and the protective cover to rotate by the rotation of the rotating rod, and adjust the opening angle of the protective cover to the back of the operating table. After the preset sealing pad or protective baffle on the machine body is docked with the opening of the adjusted protective cover, a sealing protection effect on the blade can be achieved, and the safety protection effect of the device is further increased.
