Cutting and positioning device for plastic film production

Abstract

The invention discloses a cutting and positioning device for plastic film production. The cutting and positioning device comprises a workbench, a roller shaft and a cutting chamber, the feeding end of the workbench is rotationally connected with the roller shaft, the cutting chamber is arranged on the upper surface of the workbench, a supporting frame is installed at a feeding port of the cutting chamber, the top end of the supporting frame is fixedly connected with one end of a lifting rod, and a connecting plate is installed at the other end of the lifting rod. An ion fan is detachably connected to the lower surface of the connecting plate, telescopic rods are symmetrically arranged on the two sides of the ion fan, a grid plate is detachably connected to the bottoms of the telescopic rods, the grid plate is located below the ion fan, a clamping assembly is arranged at a discharging port of the cutting chamber, and supporting plates are installed on the two sides of the clamping assembly. Static electricity on the surface of a plastic film is neutralized through the ion fan, accidents occurring due to the static electricity are effectively avoided, and the safety of a workplace is improved; and defect detection is carried out on the plastic film through a line scanning camera, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field related to plastic films, in particular to a cutting and positioning device for plastic film production. Background technique [0002] Plastic film refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as lamination layers. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] The existing cutting and positioning device for plastic film production has the following disadvantages when in use: [0004] 1. During the production and pro...

Problems solved by technology

[0006] The purpose of the present invention is to provide a cutting and positioning device for plastic film production, to solve the problem that during the production and processing of the plastic film in the above background technology, static electricity will be generated due to friction on the surface, and when the plastic film with static electricity is taken It is easy to absorb wrinkles and affect product quality. The accumulation of static electricity in a large area can easily lead to air discharge, electric shock and even fire. Requirements, the traditional detection method is manual quality inspection, in the face of mass production, there is a phenomenon of missed detection after long-term work, the detection accuracy is low, and the problem of product quality is reduced
