Description

Sew up the side cut frock

Technical field

The present invention relates to a kind of industrial stitching side cut equipment, this device-specific is in the processing leather material, and it can finish trimming technology when sewing up leather.

Background technology

Along with the raising of people's living standard, the utilization of various leather substances is more and more wider, the goods of various full skins or foreskin occurred.As a rule, the processing of these leather and fur productss all will be passed through operations such as blanking, stitching, side cut, wherein, the side cut operation is last procedure in the entire product manufacture process often, and carry out after and then sewing up operation, therefore, the trimming quality quality not only is embodied directly on the product appearance, and has reacted the processing technology level of this enterprise to a certain extent.If trimming quality does not reach requirement and will destroy the attractive in appearance of entire product, make it to become waste product.Therefore, general enterprise all pays much attention to the trimming technology in the leather and fur products processing, and the edge of product parallels with the stitch of stitching after requiring to cut edge, and forms a wide edge strip, and it is smooth, smooth and neat that the edge is accomplished.

At present, the restriction of process equipment owing to sewed up, cut edge, during the processing leather goods, stitching and side cut are respectively two independent process, sewing up operation generally adopts industrial sewing machine to finish, and the side cut operation can only rely on some simple and mechanical or manual finishing, and particularly for some edge contours and complex-shaped or irregular leather and fur products, its side cut can only be finished with manual.For example, foreskin chair (seeing accompanying drawing 9), the outline at the chair back place of this foreskin chair is irregular circular-arc, and also include metal tube between the leather of sewing up, side cut like this can only be finished by manual the shearing in the past, the workman cuts off unnecessary leather with scissors according to the outline of the chair back during operation, cuts smooth, wide edge.

Obviously, adopt existing manufacturing process stitching, side cut leather substance that following deficiency is arranged: 1, the stitching and the branch two procedures of cutting edge are carried out, and production efficiency is low; 2, side cut relies on simple machinery to finish, and can only finish with manual especially some erose goods, and time-consuming, production efficiency is low, is not suitable for producing in enormous quantities; 3, the quality of Qie Bianing can't guarantee, is prone to waste product.

Summary of the invention

The object of the invention provides a kind of efficient, high-quality and finishes leather substance and sew up tooling device with the processing of cutting edge, this equipment by transforming cleverly, has been designed a kind of stitching side cut frock that can finish stitching and side cut operation simultaneously on the basis of general industry Sewing machines.

For achieving the above object, the technical solution used in the present invention is: a kind of stitching side cut frock, comprise the industrial arm-type sewing machine of making thick material, and the suture top of this head of sewing machine is provided with big presser feet, little presser feet and eedle, and the below is provided with needle plate; Be provided with a cutting knife in big presser feet bottom, cutting knife is parallel apart with the needle route of eedle, and is positioned at the inboard of eedle, blade towards opposite with feed direction; Needle plate is provided with the roll setting groove, this roll setting groove be positioned at cutting knife under.

Related content and change interpretation in the technique scheme are as follows:

1, in the technique scheme, the described industrial arm-type sewing machine of making thick material, refer to the various tubular that bag, seat cushion, leather uniform thickness heavy material make, the industrial sewing machines of curved article of being applicable to, these Sewing machiness generally all are made of head and support, and structure and operation principle that it is inner are prior art; As being the comprehensive feed sewing machine of cartridge type (model TW3-8B) that Standard Sewing Mahcine Yuanping Machinery Co., Ltd. produces, be provided with thread take-up mechanism, needle bar swinging mechanism, depression bar drag link mechanism in the head of this Sewing machines, go up feed mechanism, down charging mechanism, rotary shuttle mechanism and cross line mechanism or the like, the power of this Sewing machines is foot pedal and motor.

2, in the technique scheme, the suture of described head of sewing machine is meant that the position is carried out in the work of Sewing machines.

3, in the technique scheme, described big presser feet is " L " shape member, and " L " shape presser feet lower end is provided with the dress tool bore, and cutting knife is inserted in this hole, and fixes by screw.

4, in the technique scheme, " described big presser feet can only be established inboard toe; the outside of needle plate is provided with the arc chord angle transition ", this the meaning is: the big presser feet on the general Sewing machines its bottom all is bifurcation shape, be provided with two toes, this programme is that the toe in its outside is removed, and makes it that inboard toe only be arranged, circular-arc with being designed to outside the needle plate simultaneously, this equipment is applicable to processes the leather that has wrapped up tubing uniform thickness section bar material.

5, in the technique scheme, described inboard, the outside, its inside and outside direction is seen accompanying drawing 1, the left side of suture 16 is the outside on the accompanying drawing 1, promptly away from the direction of equipment; The right side of suture 16 is inboard, promptly towards the direction of equipment.

Operation principle of the present invention is: be provided with cutting knife on big presser feet, and this cutting knife is the inboard that is positioned at eedle, when work, eedle and big presser feet move up and down, its action with feed mechanism of moving up and down is replacing to be carried out, eedle one pin is sewed up at leather, and the cutting knife on the simultaneously big presser feet falls into again and again in the roll setting groove of needle plate, and leather is cut off; Because of the cutting knife and the needle route of eedle be parallel apart, this apart parallel distance promptly is the width at the edge that stays of cutting edge.

Because the technique scheme utilization, the present invention compared with prior art has following advantage:

1, owing to be provided with cutting knife on the big presser feet of the present invention, eedle and cutting knife are worked simultaneously, and the stitching operation and the side cut operation of separating in the prior art combined, and finish with one procedure, have improved production efficiency greatly.

2, the present invention is provided with cutting knife on big presser feet, therefore the present invention is equally applicable to complex contour and irregular goods, solved the side cut difficult problem of existing complex contour and irregular goods, compared with manual side cut of prior art, its production efficiency has significantly improved.

3, because the present invention is provided with cutting knife on big presser feet, the parallel distance apart with the needle route of eedle of cutting knife promptly is the width at the side cut edge that stays, and its trimming quality obtains good assurance, the edge that cuts out is wide edge strip surely, and smooth, smooth.
