Abstract

The utility model discloses a filtering device of a film blowing machine. The filtering device comprises a mold head, a sieve head, a filtering pipe in the sieve head, a discharging pipe and a branched guide pipe, wherein the two ends of the filtering pipe are respectively connected with the discharging pipe and the branched guide pipe; the filtering pipe is a straight through pipe; the connecting position between the discharging pipe and the filtering pipe and the connecting position between the branched guide pipe and the filtering pipe are respectively connected with a V-shaped connecting pipe sleeve in a sheathing manner; the angle of the V-shaped connecting sleeve is 125-135 degrees; the sieve head is made of polytetrafluoroethylene; the branched guide pipe is a telescopic pipe. The filtering device also comprises a mold-head automatic cleaning device which is communicated with a tap water pipe. The filtering device disclosed by the utility model has the beneficial effects that large-angle V-shaped connecting pipe sleeve structures are adopted between the filtering pipe and the discharging pipe as well as between the filtering pipe and the branched guide pipe, so that the resistance is reduced and the fluidity is enhanced in comparison with the right-angled connection; the blocking of materials is avoided, and the smooth filtering is guaranteed; a product produced by adopting the technology has the advantages that the efficiency is high, the quality is good and automatic cleaning can be achieved.

Description

A kind of filter of inflation film manufacturing machine

Technical field

The utility model belongs to the plastic film production equipment technical field, relates in particular to a kind of inflation film manufacturing machine filter.

Background technology

The connector feeding-passage of existing plastic film blowing machine has porous plate with screen pack and is that right angle is connected with tapping channel; Angle between large vertical feeding-passage of its die head and many little horizontal tapping channels is right angle; Its discharge nozzle equates substantially with the screen pipe size.Though this inflation film manufacturing machine can be produced plastic sheeting continuously, its weak point is that resistance is large, and it is poor that temperature is controlled, and the raw material mixing time is shorter, and squeeze pressure is less, raw materials for production continuously, and easy carbonization, foaming, poor fluidity, plastify difficulty large.Be difficult to enhance productivity in production of plastic film, and easily cause in machine and stop up, and then affect product quality, and can not automatically clean.

Summary of the invention

It is high that the purpose of this utility model is to provide a kind of service efficiency, the rational in infrastructure and filter of susceptible to plugging a kind of inflation film manufacturing machine not.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of filter of inflation film manufacturing machine, the screen pipe, discharge nozzle and the bypass ducts that comprise die head, screen cloth head, screen cloth head inside, described screen pipe two ends are connected with bypass ducts with discharge nozzle respectively, described screen pipe is a straight pipe, all be socketed a V-arrangement with the screen pipe junction with bypass ducts and screen pipe junction at discharge nozzle and be connected pipe box, the angle that described V-arrangement connects pipe box is 125 °-135 °, the screen cloth head is the polytetrafluoroethylene (PTFE) material, bypass ducts is telescoping tube, also comprise the die head automatic flushing device, the die head automatic flushing device is communicated with running water pipe.

The beneficial effects of the utility model: adopt the V-arrangement tube connector nested structure of wide-angle between screen pipe and discharge nozzle and between screen pipe and bypass ducts, compared with right angle connects, reduced resistance, strengthened mobility; Avoided feed blocking, guaranteed that filtration is smooth and easy, the product that adopts this technology to produce, efficiency is high, quality good, and can automatically clean.

The accompanying drawing explanation

Figure l is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As Fig. 1, a kind of filter of inflation film manufacturing machine, the screen pipe 3, discharge nozzle 4 and the bypass ducts 5 that comprise die head 1, screen cloth head 2, screen cloth head 2 inside, described screen pipe 3 two ends are connected with bypass ducts 5 with discharge nozzle 4 respectively, described screen pipe 3 is a straight pipe, all be socketed a V-arrangement with bypass ducts 5 with screen pipe 3 junctions with screen pipe 3 junctions at discharge nozzle 4 and be connected pipe box 6, the angle that described V-arrangement connects pipe box 6 is 135 °.

Adopt the V-arrangement tube connector nested structure of wide-angle between screen pipe and discharge nozzle and between screen pipe and bypass ducts, compared with right angle connects, reduced resistance, strengthened mobility; Avoided feed blocking, guaranteed that filtration is smooth and easy, the product that adopts this technology to produce, efficiency is high, quality good, can automatically clean.

Claims

1. the filter of an inflation film manufacturing machine, comprise die head, the screen cloth head, the screen pipe of screen cloth head inside, discharge nozzle and bypass ducts, described screen pipe two ends are connected with bypass ducts with discharge nozzle respectively, it is characterized in that: described screen pipe is a straight pipe, all be socketed a V-arrangement with the screen pipe junction with bypass ducts and screen pipe junction at discharge nozzle and be connected pipe box, the angle that described V-arrangement connects pipe box is 125 °-135 °, the screen cloth head is the polytetrafluoroethylene (PTFE) material, bypass ducts is telescoping tube, also comprise the die head automatic flushing device, the die head automatic flushing device is communicated with running water pipe.
