Abstract
The utility model aims to provide a transmission mechanism of the dial linking machine with simple structure, few moving orbits, reliable transmission, little noise, which adopts a lifting pole, a connecting axis, a tie-in that is connected with the lifting pole of the cam wheel driver, a connecting rod seat is connected with one end of the tie-in, a connection shaft that is arranged on the connecting rod seat. The utility model has the advantages of timelagging the movement via the single wheel curves and making the coiling driving gear obtain timelagging arc movement by the method of adopting axis core style coiling, thereby making the stitches form stable loop during the process of needling to stitch various wool yarn fabrics and obtain satisfied effect and making the procedures of transmission and taking-up threads much more reliable.
Description
Technical field
The utility model relates to and a kind of two fabrics is carried out the stitching of needle cycle to needle cycle, often refer to fabric shoulder seam, hang shoulder seam, also as the drive mechanism of clothing body with the sewing machine of sleeve, neck stitching.
Background technology
Sewing machine is the main robotic suturing device of woolens industry, be applicable to kinds of processes such as stitching, connection, edge assembly, pressing, reinforcing, the decoration processing of garment piece, parts, enriched the style kind of knitted product, production efficiency and product quality have been improved, having increased the taking and the value of art appreciation of knitwear, is the indispensable equipment of sweater producer.
Existing sewing machine is by two bull wheel drive link, and the transmission catch walking number step is finished winding process.It is many that the line of this long line pull bar transmission stroke is counted track, makes the terminal works instability, its drives structure complexity, the operation loaded down with trivial details.This transmission mechanism quick abrasion, and realize that the mechanism of these motions drives by eccentric wheel or cam driven connecting rod to finish, noise is big during operation, and bull wheel precision prescribed height, and centrifugal force is big, and quick abrasion makes the frequency of maintenance height, uses comparatively inconvenience.
Summary of the invention
The utility model be intended to provide a kind of simple in structure, running orbit is few, the drive mechanism of reliable transmission, sewing machine that noise is little.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
A kind of sewing machine drive mechanism includes and shoulders bar, connecting axle, and the cam-actuated bar of shouldering is connected with joint, and the joint other end connects connecting rod base, and connecting rod base is provided with connecting axle.
Compared with prior art, beneficial effect described in the utility model is by single-wheel curve time-delay motion, adopt axle core formula method for winding, making the coiling driven wheel obtain the time delay arc rotates, thereby make suture in the suture needle process, form stable wire loop, prevented loose ends ring (bouncing pilotage), the generation of the yarn that looses, sew up various wool yarn wire fabrics and all obtain promising result, improved the adaptive capacity and the quality of sewing machine greatly.The utility model is simple in structure, and abrasion and the noise of having avoided the direct frictions of two cover bull wheel drivening rod transmissions to produce use the short connecting rod structure, are difficult for producing resonance, makes transmission, take-up program more reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is Fig. 1 three-dimensional element figure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Cam 1 inner ring is provided with tongue, and there is circular groove its outer ring.Shoulder the tongue that bar 2 ends place cam 1, its another termination places cam 1 outer ring circular groove.Shoulder bar 2 by shouldering rod bearing 3 jointings 4, joint 4 other end hinge connecting rod bases 5, connecting rod base 5 is provided with connecting axle 6, and connecting rod base 5 connects driven wheels 7 by connecting axle 6.
When motor-driven cam 1 rotates, shouldering bar 2 is the center with the termination that places cam 1 outer ring circular groove, another places the termination of cam 1 tongue to do intermittent swing with the height point of cam 1 to shoulder bar 2, shoulder bar 2 and be delivered to joint 4 by shouldering rod bearing 3, make the connecting rod base 5 of joint 4 other end hinges produce the time delay rotation, the round arc that the driven wheel 7 that connecting axle 6 is connected produces intermittently changes, and promptly the time delay arc rotates.
Above illustrated embodiment is only with for conveniently illustrating the utility model, and at technical scheme category described in the utility model, the person of ordinary skill in the field does various simple deformation and modification, all must be included in the above claim.
