The invention provides a plastic film punching device. The plastic film punching device comprises a rack, a film transmission unit, a first punching unit, a second punching unit and a programmable controller. The lower surface of the top of the rack is in sliding connection with the first punching unit, and the position, right opposite to the first punching unit, of the upper surface of the bottom of the rack is in sliding connection with the second punching unit. The film transmission unit is arranged at the middle portion of the rack. Each of the first punching unit and the second punching unit comprises a sliding plate, a first air cylinder, a second air cylinder and a punching end portion. The sliding plates are in sliding connection with the top or the bottom of the rack. The first air cylinders are fixed to the sliding plates. One ends of the sliding plates are connected with the second air cylinders fixed to the side walls of the rack. The first air cylinders are connected with the punching end portions. By means of the plastic film punching device, punching uniformity can be guaranteed, local curling of the surface of a film can be avoided, and meanwhile the punching efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of plastic product processing equipment, in particular to a plastic film punching device. Background technique [0002] In the technological process of various plastic film processing, in order to meet the needs of packaging, it is often necessary to punch holes in various plastic films. However, most of the punching in the prior art is single-sided punching, which easily leads to partial curling due to uneven surface tension of the film, and the punching aperture is not uniform enough. Contents of the invention [0003] In view of this, the present invention aims to propose a plastic film punching device to overcome the defects of the prior art, the punching is uniform, and the film surface is not easy to partially curl. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A plastic film punching device, comprising a frame, a film transfer un...
