Description

The knitting needle drives structure of quilting machines

Technical field

The utility model relates to the quilting machines technical field, especially relates to the knitting needle drives structure without the shuttle quilting machines.

Background technology

Quilting machines is a kind of machinery to the fabric processing graphic pattern, on quilting machines, has type throwing mechanism to coordinate and sew with long stitches embroidery art's work for defeated line, and the quilting line is transported to knitting needle, and knitting needle moves up and down and realizes making in conjunction with string-hooking mechanism, thereby forms pattern on fabric.Traditional knitting needle motion is to be driven by distant linkage, but this structure is to drive spininess work simultaneously, is difficult to realize the selected control of single needle, have subsequently the structure of utilizing the cylinder single needle to drive, it can stop arbitrarily or drive single needle work as required, but fixing needle stand is the circular shaft structure be coupling with the cylinder piston axle for knitting needle, this needle stand activity is located in the circular guide holes of corresponding holder, owing to only thering is leading directly on axis direction between circular shaft and circular guide holes, and lack restriction for relatively rotating between circular shaft and circular guide holes, so that knitting needle moves up and down in process, be subject to fabric and the quilting line is pullled the situation that can rotate, thereby cause string-hooking mechanism can't complete the hook line, the pattern discontinuity also just appears, even can't complete quilting work, cause quality of production defect, bring adverse effect to production, also cause waste of material and cost of manufacture to increase.

The applicant is because defect and the inconvenience of the knitting needle drives structure of above-mentioned known quilting machines, and the spirit of adhering to research and innovation, keeping on improving, utilize professional eye and professional knowledge, has proposed a kind of knitting needle drives structure of novel, stable quilting machines.

Summary of the invention

The purpose of this utility model is to overcome the defect of prior art, provides a kind of simple in structure, easily makes, and can effectively prevent knitting needle deflection, promotes the knitting needle drives structure of the quilting machines of quilting job stability and accuracy.

For achieving the above object, the utility model adopts following technical scheme:

The knitting needle drives structure of quilting machines, this drives structure has the cylinder body of an exportable flexible power, the external part group of cylinder body is established a flexible needle stand of piston of following cylinder body, the needle stand Moveable assembled is in the guide hole of a holder, at least be provided with one on needle stand and scabble face, and the shape of the guide hole of holder, size and needle stand are complementary; Described knitting needle fixedly group is located on needle stand.

Such scheme is further: the section of described needle stand and the guide hole of holder are be complementary square.

Such scheme is further: described holder is provided with the operation window that is communicated with guide hole, and guide hole vertically designs, and the operation window is positioned at the face side of holder vertical with guide hole.

Such scheme is further: described cylinder body is cylinder.

Such scheme is further: the guide hole of described holder can be and the holder integrated molding is made, can also be molded over one with the external member of holder combination on.

The knitting needle drives structure that the utility model provides, at least be provided with one and scabble face on its needle stand, and the shape of the guide hole of holder, size and needle stand are complementary; The anti-deflection characteristic of face is scabbled in utilization, can effectively prevent knitting needle deflection, guarantees normally to hook the lineman and does, and promotes quilting job stability and accuracy.

The utility model advantage again is simple in structure, and scientific and reasonable, cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, greatly improved operation ratio and the operability of equipment, promotes industry innovation, widely applicable, meets the industry utilization.

the accompanying drawing explanation:

The structural representation that accompanying drawing 1 is the utility model one embodiment;

The needle stand contour structures schematic diagram that accompanying drawing 2 is Fig. 1 embodiment.

the specific embodiment:

Below in conjunction with accompanying drawing, the utility model is further illustrated:

Consult shown in Fig. 1,2, the knitting needle drives structure of the relevant a kind of quilting machines of the utility model, this drives structure has the cylinder body 1 of an exportable flexible power, and cylinder body 1 is cylinder, and work is clean and tidy and cost is low.The external part group of cylinder body 1 is established a flexible needle stand 2 of piston of following cylinder body 1, and needle stand 2 Moveable assembleds, in the guide hole 31 of a holder 3, at least are provided with one and scabble face on needle stand 2, and the shape of the guide hole 31 of holder 3, size and needle stand 2 are complementary; Described knitting needle 4 fixedly group is located on needle stand 2.Like this, the anti-deflection characteristic of face is scabbled in utilization, needle stand 2 of the present utility model not only can realize that traditional axis direction leads straight flexible, also can effectively prevent knitting needle 4 deflections, on knitting needle 4, coordinate the notch position 41 of string-hooking mechanism can accurately keep the motion orientation, guarantee normally to hook the lineman and do, promote quilting job stability and accuracy.

Shown in Fig. 1,2, in the present embodiment, the guide hole 31 of the section of described needle stand 2 and holder 3 is square for what be complementary, the restriction of side face multiple spot, the anti-deflection superior performance, simple in structure, scientific and reasonable, cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, operation ratio and the operability of equipment have greatly been improved, the innovation of the promotion industry, widely applicable, meet the industry utilization.
