Open-end spinning combing roller needle ring
Technical field:
The utility model relates to textile technology, is employed parts on a kind of open-end spinning loom, specifically, is a kind of open-end spinning combing roller needle ring.
Background technology:
Existing open-end spinning combing roller, most modes that adopt monoblock type winding card clothing need be reprocessed after the card clothing wearing and tearing, and the replacement cycle is long, and the number of rewelding increase, makes it overproof and cause whole roll body to scrap, and causes very big waste of raw materials.
Summary of the invention:
The purpose of this utility model provides a kind of easily manufactured, and is simple in structure, and open-end spinning combing roller needle ring is easily installed, uses, changed to long service life.
Technical solution of the present utility model is: a kind of open-end spinning combing roller needle ring is characterized in that: the needle ring matrix is arranged, have helical groove on the cyclic group body, the combing roller card clothing that embeds in the groove is wrapped on the cyclic group body.
Groove on the needle ring matrix described in the utility model is a spiral U type groove.The width of the spiral U type groove on the needle ring matrix is consistent with the width of the base portion of combing roller card clothing.The endoporus of needle ring matrix is a stepped form.Be installed in the crown rotation direction unanimity of the combing roller card clothing in the spiral U type groove on the needle ring matrix.
The beneficial effects of the utility model are: simple in structure, and long service life, it is convenient to install, use, change.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of a kind of open-end spinning of the present utility model with the combing roller needle ring;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of employed combing roller card clothing in the utility model;
Fig. 4 is the side view of Fig. 3.
The specific embodiment:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 have described an embodiment of the present utility model jointly.The needle ring matrix 1 that it is made by metal material (as aluminium section bar), combing roller card clothing 2 adopts with needle ring matrix 1 the spiral U type groove winding on the base portion embedding needle ring matrix 1 of combing roller card clothing 2 is formed, U type groove local deformation by needle ring matrix 1 makes crushed element compress card clothing 2 base portions and base groove and both is linked together again, plays the fixedly effect of card clothing.
The width of the spiral U type groove of needle ring matrix 1 adopts tight fit with card clothing 2 base portion consistency of thickness, and the combing roller card clothing can adopt high-carbon steel or low-alloy high-carbon steel to make.
