Abstract

The utility model discloses a fixing device of a plastic extruder filter. The fixing device of the plastic extruder filter comprises a barrel body. A plurality of parallel spiral guide grooves are positioned in the inner wall of the barrel body. A discharge port is arranged in a barrel wall. An axially longitudinal guide groove is further arranged in the position of the discharge port. The longitudinal guide groove is communicated with the spiral guide grooves and the discharge port. The fixing device of the plastic extruder filter is used with a laminate cylinder type filter in matched mode and has the two functions of fixing and guiding.

Description

The fixture of filtering device of plastic extruder

Technical field

The utility model relates to the plastic extrusion machine technology, specifically a kind of fixture of filtering device of plastic extruder.

Background technology

The filter of plastic extruder is one of core component of extruder, the present flat and cartridge type to mainly containing of filter, no matter flat or cartridge type manufacture process the most difficult be exactly boring, stamp thickly dotted filter bores at one flat plate or cylinder, take time and effort very much, cost is also very high, simultaneously owing to needing boring, thereby the material of filter can not be too hard, as adopt the hard material such as wolfram steel just can't hole at all, and extruder mainly is used for processing recovery waste or used plastics, in these waste or used plastics, contain a large amount of impurity, it wherein much is the very high metal of hardness, can cause very large damage to filter like this in extrusion process, the in use for some time surface abrasion filter bores distortion of all existing filters is stopped up, and is shabby often, had a strong impact on service life, the applicant invents a kind of annular thin slice that adopts by the drum type brake filtering device of plastic extruder of stacked fixedly formation for this reason.

The utility model content

The purpose of this utility model is to provide a kind of fixture of filtering device of plastic extruder, and this device cooperates stacked cylindric style filter to use, and plays the fixedly double function of guide.

For achieving the above object by the following technical solutions:

A kind of fixture of filtering device of plastic extruder, comprise a cylindrical shell, it is characterized in that: offer some parallel spiral deflector chutes at cylinder inboard wall, offer discharging opening at barrel, also offer axial vertical deflector chute in the position of discharging opening, vertically deflector chute is communicated with spiral deflector chute and discharging opening.

The utility model cooperates stacked cylindric style filter to use, the structure of tubular and filter form coupling and play fixation, simultaneously cylinder inboard wall arranges parallel spiral deflector chute, deflector chute is connected logical with the blow tank of stacked cylindric style filter outer wall, the regenerated plastics raw material that squeezes out is sent to vertical deflector chute, extrude from discharging opening at last, the utility model had both played the effect of Fixed-Filter, also played simultaneously the function of guide.

Description of drawings

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

Fig. 2 is the utility model internal structure schematic diagram;

Fig. 3 is the structural representation that the utility model cooperates with filter.

The specific embodiment

As Figure 1-3, a kind of fixture of filtering device of plastic extruder, comprise a cylindrical shell 1, offer some parallel spiral deflector chutes 2 at cylindrical shell 1 inwall, offer discharging opening 4 at barrel, also offer axial vertical deflector chute 3 in the position of discharging opening 4, vertically deflector chute 3 is communicated with spiral deflector chute 2 and discharging opening 4.

The utility model cooperates stacked cylindric style filter to use, and cylinder inboard wall and stacked cylindric style filter are crossed outer wall and contacted and play fixation, prevent that the thin slice of stacked cylindric style filter from breakking away; Cylinder inboard wall arranges parallel spiral deflector chute in addition, deflector chute is connected logical with the blow tank of stacked cylindric style filter outer wall, blow tank avoids cylinder inboard wall to stop up the outlet material mouth of filter bores, and the regenerated plastics raw material that squeezes out is sent to vertical deflector chute by the spiral deflector chute, flow out from discharging opening at last, the utility model had both played the effect of Fixed-Filter, also played simultaneously the function of guide.

Claims

1. the fixture of a filtering device of plastic extruder, comprise a cylindrical shell, it is characterized in that: offer some parallel spiral deflector chutes at cylinder inboard wall, offer discharging opening at barrel, also offer axial vertical deflector chute in the position of discharging opening, vertically deflector chute is communicated with spiral deflector chute and discharging opening.
