Punching and deburring device for polyethylene resin film

Abstract

The invention provides a punching and deburring device for a polyethylene resin film, and relates to the field of plastics. The punching and deburring device for the polyethylene resin film is used for conveying the plastic film, and comprises a workbench, wherein two traction rollers are arranged on the workbench, and a support plate is arranged on the workbench. According to the punching and deburring device for the polyethylene resin film, needle holes are formed in the workbench, steel needles are installed on a transverse plate, and electric push rods electrically drive the transverse plate to lift so that the steel needle can puncture the plastic film, so that the plastic film is punched; an air pump, air bags, expanding rods and rubber bands are matched mutually, so that the overalldiameters of the steel needles are changed so as to punch the holes with different specifications, and the application range of the whole device is improved; a sliding strip, a spring, a cutting block, a steel wire and a motor are matched mutually so that the cutting block can move back and forth to smooth burrs generated by punching, so that the manual operation steps are reduced, and the laborcost is further reduced; and moreover, the burrs are processed while punching, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a punching and deburring device for polyethylene resin films. Background technique [0002] Films made of polyethylene and other resins are currently mainly used for packaging and as laminating layers. Usually, the shape of the plastic film after actual production is a continuous strip-like structure. Plastic films used for packaging often also need to be perforated. [0003] Existing punching equipment generally needs to unwind the plastic film in rolls, spread the plastic film flat, and then punch holes with a punching machine. However, the traditional punching method is processed manually. Workers will fold the plastic film multiple times and then punch holes. [0004] However, the work efficiency of punching a hole in a single-layer film is extremely low. In order to increase the punching speed, workers generally fold the plastic film several times before punching. Worke...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a punching and deburring device for polyethylene resin films, which solves the problem of punching holes in plastic films in the above-mentioned background technology by manual operation and piercing with steel needles. After the film is punched, it is time-consuming and labor-intensive to punch holes, and the punching efficiency is relatively slow
