Abstract
The invention discloses a pressure foot cam mechanism for a computerized embroidering machine. The pressure foot cam mechanism for the computerized embroidering machine comprises a cam supporting piece, a pressure foot cam and a locking sleeve, wherein the cam supporting piece comprises a sleeve body and a connecting body arranged at the rear part of the sleeve body; first notches are uniformly distributed in the front end of the sleeve body; the sleeve body is sleeved by the pressure foot cam and the locking sleeve; the pressure foot cam is arranged between the connecting body and the locking sleeve and is fixedly connected with the connecting body; the sleeve body is fixedly connected with a driving shaft of a machine head through the locking sleeve. Compared with the prior art, the pressure foot cam mechanism for the computerized embroidering machine has the advantages that the service life is prolonged; the synchronous matching degree between a pressure foot and a needle bar is increased; the self-lubrication is improved; the noise is greatly reduced.
Description
[technical field]
The present invention relates to the presser feet cam mechanism on high speed machine head of computer embroidery machine, after being characterized in using this cam mechanism, the synchronous matching degree of presser feet and shank increases, and service life increases.
[background technology]
Of the prior art, the presser feet cam rigidity of polyformaldehyde material is limited, and heat endurance is poor, and self lubricity is also poor, contacts work at work with back-up ring, easily produces deformation.The pulley groove discontinuity of presser feet cam produces concentrated wear, and wearing and tearing are accelerated and the synchronous matching degree that affects presser feet and shank reduces, noise comparatively greatly simultaneously, presser feet cam fatiguability damage and rupturing.
[summary of the invention]
Object of the present invention solves the problems of the prior art exactly, proposes a kind of presser foot of computerized embroidery machine cam mechanism, can increase service life, and the synchronous matching degree of presser feet and shank increases.
For achieving the above object, the present invention proposes a kind of presser foot of computerized embroidery machine cam mechanism, comprise cam support, presser feet cam and lock sleeve, described cam support comprises body and is located at the connector at body rear portion, the front end of described body is evenly distributed with the first otch, on described body, cover has presser feet cam and lock sleeve, described presser feet cam is located between connector and lock sleeve, described presser feet cam is fixedly connected with connector, and described body is fixedly connected with the driving shaft of head by lock sleeve.
As preferably, described lock sleeve comprises body, screw hole and the second otch, the upper side wall of described body is provided with the screw hole of horizontally set and the second otch of longitudinally setting, and described second otch cuts off screw hole, and the lower end of described second otch arranges the inwall to body.
As preferably, described lock sleeve is enclosed within the first incision, and the length of described first otch is equal to or greater than the thickness of lock sleeve.
Beneficial effect of the present invention: the present invention is by having presser feet cam and lock sleeve by cover on body, presser feet cam is located between connector and lock sleeve, presser feet cam is fixedly connected with connector, body is fixedly connected with the driving shaft of head by lock sleeve, connector strengthens the intensity of presser feet cam, deformation reduces greatly, reliable transmission is high, can increase service life, the synchronous matching degree of presser feet and shank increases, and presser feet cam adopts the modified polyformaldehyde material adding lubricant and quieter material to make, and self lubricity improves, and noise significantly reduces.
Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.
