Plastic packing machine special for screen mesh and plastic packing method

Abstract

The invention belongs to the technical field of plastic packing machines, and discloses a plastic packing machine special for a screen mesh and a plastic packing method. The plastic packing machine is characterized by comprising a feeding mechanism, a plastic film packing mechanism, a truncating and sealing mechanism, a heat-seal edge pressing mechanism, an overall heat shrinkable bin, a power mechanism and a control mechanism. According to the plastic packing machine, packed screen mesh coils are conveyed into the overall heat shrinkable bin to be heat shrank to allow a plastic film to tightly wrap on the outer side of the screen mesh coils, thus, labor intensity is reduced greatly, operating efficiency is improved greatly, and the plastic file is damaged rarely during packing.

Description

technical field [0001] The invention belongs to the technical field of overmolding machines, and in particular relates to a special overmolding machine for wire mesh and an overmolding method. Background technique [0002] In the field of wire mesh production, in order to facilitate storage and transportation, wire mesh rolls often need to be packaged. At present, paper packaging and plastic packaging are mainly used for packaging. The above two kinds of packaging have the following defects: one, paper packaging, high cost, poor moisture-proof performance, easy to corrode the wire mesh during storage or transportation, causing the wire mesh to rust; second, plastic packaging, although plastic packaging Overcome the above defects, but mainly manual packaging, first lift the screen roll, put it into the cylindrical plastic film, then cut off the plastic film at both ends of the screen roll, and then heat shrink the plastic film, not only labor intensive, Moreover, the labor e...

Problems solved by technology

The above two kinds of packaging have the following defects: one, paper packaging, high cost, poor moisture-proof performance, easy to corrode the wire mesh during storage or transportation, causing the wire mesh to rust; second, plastic packaging, although plastic packaging Overcome the above defects, but mainly manual packaging, first lift the screen roll, put it into the cylindrical plastic film, then cut off the plastic film at both ends of the screen roll, and then heat shrink the plastic film, not only labor intensive, Moreover, the labor efficiency is low. In the process of bagging or moving the non-heat-shrinkable plastic film, it is easy to scratch the plastic film, resulting in air leakage of the plastic film, poor corrosion resistance, and easy damage to the plastic film during the heat-shrinking process.
