Preservative film cutting device capable of preventing edge from curling during cutting

Abstract

The invention discloses a preservative film cutting device capable of preventing an edge from curling during cutting. The device comprises a base, a chain wheel and a micro water pump, a main shaft is connected to the left side inside the base through a bearing, a driven shaft is connected to the interior of the left side of the chain wheel through a key, supporting columns are correspondingly welded to the left side and the right side of the bottom of the base, a connecting shaft is connected to the lower portion of the inner side of the base through a bearing, a water inlet pipe is hermetically connected to the left side of the micro water pump through a hoop, and a water suction roller and a hair collecting roller are connected to the left side inside the base through a movable shaft. According to the preservative film cutting device capable of preventing the edge from curling during the cutting, a cutter is installed, so that oil liquid can be extruded to the inner side of a second telescopic rod through an oil cylinder under the action that a foot treads a treading plate and is matched with downward movement of a first telescopic rod and a reset spring, and therefore, the cutter at the bottom of the second telescopic rod effectively cuts a preservative film connected with a first winding drum and a second winding drum in cooperation with a connecting roller.

Description

Technical field[0001]The present invention relates to the field of plastic wrap, in particular a shut-off apparatus for preventing curling film in the edge of the shear.Background technique[0002]The role of plastic wrap is very wide, for example, can be used for the bundle of mechanical parts, packaging of fresh fruit and vegetables, sealed and refrigerated refrigeration, plastic wrap can be divided into three categories, the first is polyethylene, referred to as PE, the second is polyvinyl chloride, referred to as PVC, and the third is polyvinyl chloride, referred to as PVDC, wherein the first polyethylene and the second polyvinyl chloride are generally used for semi-finished fruits and vegetables packaging, and the third A polydlorethylene vinyl can be refrigerated with a cooked seal package, and the plastic wrap needs to be used in the production of winding rolls, and the winding apparatus and cutting devices in the market in the market still have imperfections, such as:[0003]1. ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a cutting device for plastic wrap that can avoid curling of the edge during cutting, to solve the above-mentioned background technology. There are certain health hazards when using plastic wrap to package food, and after the existing plastic wrap cutting device has finished cutting the plastic wrap, the edge will curl after cutting the plastic wrap, causing the end of the cut plastic wrap to be disobedient, thus A problem that seriously affects the appearance of the entire plastic wrap
