Abstract

The utility model discloses a filtering device of a cable extruding machine. The filtering device of the cable extruding machine comprises a filtering cylinder body (1) connected with a machine head of the extruding machine, wherein a plurality of sieve pores (2) are formed in one end face of the filtering cylinder body (1); a zigzag structure (3) is formed at the other end of the filtering cylinder body (1); the zigzag structure (3) is contacted with a filter screen; a guide flow section (4) is formed from the zigzag structure (3) to the other end of the filtering cylinder body (1) and is of a trumpet-shaped structure. The filtering device of the cable extruding machine improves the contacting mode of the filtering device and the end face of a spiral cylinder of a machine body in the extruding process of the cable extruding machine, so that the machine head, the filtering device, the filter screen and the end face of the spiral cylinder of the extruding machine are combined organically, the structure is stable, a good effect of sealing melted plastic is achieved, the material leakage phenomenon in the extruding process of the cable is greatly reduced, production efficiency is improved, and the material cost is reduced.

Description

A kind of cable extruding machine filter

Technical field

The utility model relates to a kind of filter, is specifically related to a kind of cable extruding machine filter, belongs to the cable technology field.

Background technology

At present, most of cable extruding machine filter plate body end faces are plane, in the head installation process, by the filter end face, screen pack are pressed to the extruding machine barrel end face, and then firm effect handing-over head and the extruder neck by flange is connected as a single entity.

In this process; often there will be screen pack to lay out-of-flatness; cause filter really not to be in place; gap appears in the head made and machine neck junction, and along with the rotation of extrusion screw rod, the rising of machine barrel internal pressure and temperature; the plastics of melting can flow out along gap; this is not only the waste on materials'use, also can cause extrusion pressure and gel quantity to be affected, and has also affected to a certain extent the product quality of cable.

The utility model content

The deficiency existed for prior art, the utility model purpose is to provide a kind of cable extruding machine filter, and head and machine neck are combined closely, and has avoided the waste of material, has improved the product quality of cable.

To achieve these goals, the utility model is to realize by the following technical solutions:

The utility model comprises the filtration barrel body be connected with the head of extruder; An end face at filtration barrel body is provided with a plurality of sieve apertures, and the other end of filtration barrel body is zigzag structure, and zigzag structure contacts with screen pack; The other end from the zigzag structure to the filtration barrel body is diversion section, and diversion section is flared structure.

Improved original way of contact, made the head of extruder tightr with being connected of machine neck, structure is more stable.By the drainage of diversion section, make the head that passes through extruder that the plastics of melting can be more stable, more closely knit and mould extrude and be expressed on the cable semi-finished articles, improved the presentation quality of cable plastics sheath.

A plurality of above-mentioned sieve apertures are uniformly distributed.

The utility model has been improved cable extruding machine in extrusion, the way of contact of filter and fuselage barrel end face, make head, filter, screen pack, the organic combination of extruding machine barrel end face, structure is more stable, plastic seal to melting is better, greatly reduce the phenomenon of leaking material in the cable extrusion, improved production efficiency, reduced material cost consumption.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The side view that Fig. 2 is Fig. 1.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

Referring to Fig. 1 and Fig. 2, the utility model comprises the filtration barrel body 1 be connected with the head of extruder.

Be provided with a plurality of (at least two) sieve aperture 2 in the lower surface of filtration barrel body 1, a plurality of sieve apertures 2 are uniformly distributed.

The upper end of filtration barrel body 1 of the present utility model is zigzag structure 3, and zigzag structure 3 contacts with screen pack.

The utility model is by the improvement to the contact jaw face, make head, filter, screen pack, extruding machine barrel end face to combine closely, when the plastics that guarantee melting circulate smoothly, avoided the parts loose contact, and make the phenomenon of material generation leakage current, improve production efficiency, reduced material cost consumption.

From zigzag structure 3 to filtration barrel body, 1 lower end is diversion section 4.

Wherein, diversion section 4 is flared structure, and the cross-sectional area of lower surface is greater than the cross-sectional area of upper surface.

By the drainage of diversion section 4, make the head that passes through extruder that the plastics of melting can be more stable, more closely knit and mould extrude and be expressed on the cable semi-finished articles, improved the presentation quality of cable plastics sheath.

The utility model has been improved cable extruding machine in extrusion, the way of contact of filter and extruding machine barrel end face, by original plane formula contact improvement, it is the jagged line contact, after making and installing screen pack additional, avoided causing the untight situation of contact because of the out-of-flatness of screen pack, overall structure is more stable, plastic seal to melting is better, greatly reduce the phenomenon of leaking material in the cable extrusion, improved production efficiency, reduced material cost consumption.

By the drainage of guide face, make the extruder head that passes through that the plastics of melting can be more stable, more closely knit extrude cable conductor with mould or become the cable core outside, improved the cable product presentation quality.

Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
