Thermal cutting device for woven bags

Abstract

The invention discloses a thermal cutting device for woven bags. The thermal cutting device is characterized in that a plurality of struts are vertically connected on the lower surface of a top plate to support the top plate; a pneumatic cylinder is fixed to the upper surface of the top plate; a piston rod of the pneumatic cylinder penetrates through the top plate from top to bottom to be connected with a cutting block below the top plate; the bottom of the cutting block has a cutting edge; an electric heating block is arranged inside the cutting block; air pumps are fixed to the top plate; inlets of the air pumps are connected with one ends of first air suction pipes; outlets of the air pumps are connected with exhaust pipes; one ends of second air suction pipes are inserted into the other ends of the first air suction pipes in a sliding manner; the other ends of the second air suction pipes are connected with air suction pressing blocks; the second air suction pipes slide relative to the first air suction pipes to drive the air suction pressing blocks to move up and down; a plurality of air holes which communicate with the second air suction pipes are formed in the bottoms of the air suction pressing blocks; telescopic cylinders are fixed to the lower surface of the top plate; and piston rods of the telescopic cylinders are connected with the air suction pressing blocks. According to the thermal cutting device, exhaust gas can be sucked away, and the cutting precision can be improved.

Description

Technical field [0001] The invention relates to the field of plastic product manufacturing, in particular to a thermal cutting device for woven bags. Background technique [0002] Woven bags, also known as snakeskin bags. It is a kind of plastic used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. In the manufacturing process of woven bags, they will be cut to obtain the right size. The woven bag is woven from several thin plastic strips. If it is cut directly with a knife, the thin plastic strips at the cutting seam will separate from each other, and the woven bag may disintegrate. In order to prevent the disintegration of the woven bag, it is also necessary to perform thermoplastic edge sealing at the cut seam, which has low processing efficiency. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems of the prior art and provide a thermal ...

Problems solved by technology

The woven bag is woven by several thin plastic strips. If you cut it directly with a knife edge, the plastic thin strips will separate from each other at the cutting seam, and the woven bag may disintegrate.

In order to prevent the disintegration of the woven bag, it is also necessary to carry out thermoplastic edge sealing on the cut seam, and its processing efficiency is low
