Abstract

The utility model relates to a blowing cutting device of PE membrane, its characterized in that: it includes a plurality of hoppers (1), and wherein the discharge gate of every hopper (1) all is linked together with the feed inlet of blowing machine (3) through screw extruder (2), is provided with between lower withdrawing roll (6) and wind -up roll (7) one cutting support (8), connect through horizontal pole (9) in the middle of the cutting support (8), the front side of horizontal pole (9) is provided with a plurality of cutting device (10), and cutting device (10) activity sets up on cutting support (8) to can be for horizontal pole (9) parallel translation. This kind of blowing cutting device of PE membrane can prolong the heat dissipation time of high temperature PE membrane through upwards putting down the rolling again after the drawing with high temperature PE membrane to can make the PE membrane accomplish the cutting before the rolling, improve production efficiency, it is linked together with a plurality of screw extruder to set up a plurality of feed inlets simultaneously on the blowing machine to can add multiple raw materials simultaneously and carry out the compounding, improve production efficiency.

Description

The blowing cutter sweep of PE film

Technical field

This utility model is related to a kind of blowing cutter sweep of PE film, for making PE protecting film.

Background technology

PE film entitled Polyethylene entirely, is the simplest macromolecular organic compound of structure, and its Special polyethylene is moulded Material thin film is base material, is the most widely used macromolecular material in the world today.PE film, after resins synthesis, can serve as medicine Packaging film, food package film, Coloured film, shrink film, special with film etc..

These PE films, when producing, need for plurality of raw materials to add blow molding in blow moulding machine.But conventional blow moulding machine After producing PE film, need to treat that its cooling could transfer station be cut, its production efficiency is not high；Simultaneously conventional equipment When raw material is mixed, due to needing to add plurality of raw materials, but charge door size is limited, needs repeatedly to feed intake and just can be mixed Material blowing, leads to the production efficiency of PE film not high.

Content of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides one kind to complete to produce on same station, and can To be simultaneously introduced plurality of raw materials, improve the blowing cutter sweep of the PE film of production efficiency.

The purpose of this utility model is realized in：

A kind of blowing cutter sweep of PE film, it includes multiple hoppers, and wherein the discharging opening of each hopper is all by screw rod Extruder is connected with the charging aperture of blow moulding machine, and the top of described blow moulding machine opens up discharging opening, the high temperature PE film of blow molding from The discharging opening of blow moulding machine twines on top roller by upper withdrawing roll, is subsequently wound into wind-up roll by the lower withdrawing roll of lower section from top roller, And lower being provided between withdrawing roll and wind-up roll is connected by cross bar in the middle of a cutting support, cutting support, and PE film is from cross bar Top is wound around to be passed through, and the front side of described cross bar is provided with multiple cutter sweeps, and cutter sweep is movably set on cutting support, and And can move in parallel with respect to cross bar.

Compared with prior art, the beneficial effects of the utility model are：

The blowing cutter sweep of this PE film puts down winding again by after being pulled up high temperature PE film, can extend high temperature The radiating time of PE film, such that it is able to make PE film complete to cut before winding, improve production efficiency；Open up on blow moulding machine simultaneously Multiple charging apertures are connected with multiple screw extruders, carry out batch mixing such that it is able to be simultaneously introduced plurality of raw materials, improve production Efficiency.

Brief description

Fig. 1 is the structural representation of the blowing cutter sweep of this utility model PE film.

Fig. 2 is cutting support, cross bar, the annexation figure of cutter sweep in Fig. 1.

Wherein：Hopper 1, screw extruder 2, blow moulding machine 3, upper withdrawing roll 4, top roller 5, lower withdrawing roll 6, wind-up roll 7, cutting support 8th, cross bar 9, cutter sweep 10.

Specific embodiment

Referring to Fig. 1 and Fig. 2, this utility model is related to a kind of blowing cutter sweep of PE film, and it includes multiple hoppers 1, its In the discharging opening of each hopper 1 be all connected with the charging aperture of blow moulding machine 3 by screw extruder 2, the top of described blow moulding machine 3 Open up discharging opening, the high temperature PE film of blow molding twines top roller 5 from the discharging opening of blow moulding machine 3 by upper withdrawing roll 4, subsequently from top Roller 5 is wound on wind-up roll 7 by the lower withdrawing roll 6 of lower section, and is provided with a cutting between lower withdrawing roll 6 and wind-up roll 7 Frame 8, is connected by cross bar 9 in the middle of cutting support 8, and PE film is wound around from cross bar 9 top and passes through, and the front side of described cross bar 9 is provided with Multiple cutter sweeps 10, cutter sweep 10 is movably set on cutting support 8, and can move in parallel with respect to cross bar 9, thus The cutting width of PE film can be adjusted.
