Abstract

The utility model provides a reducing sewing machine which comprises a needle dial formed by thrusting needles in a surrounded mode and a sewing component. The sewing component is arranged on one side of the needle dial, a separation blade for peeling a sweater is arranged at the periphery of the needle dial, the thrusting needles are movably connected with the needle dial through a stretchable component which can move in the radial direction of the needle dial, the stretchable component is driven by a driving component, the stretchable component expands when passing through the sewing component, the thrusting needles of the reducing sewing machine are arranged on the stretchable component, therefore, different distances are reserved between the thrusting needles on the needle dial and the axis of the needle dial, namely the thrusting needles are different in radius, accordingly the sweater located on the thrusting needles are expanded, the sewing density of the sweater is larger, and the sewing of the sweater is firm.

Description

The reducing sewing machine

Technical field

The utility model relates to weaving robotic suturing device field, especially, is a kind of sewing machine that changes stitch pitch.

Background technology

Sewing machine is the abbreviation of disk sewing machine, is commonly called as " binding-off machine ", uses suture to sew up the machine of sweater running-on.By sewing machine, can complete efficiently, fast the knitting of sweater, greatly increase work efficiency.It is greatly double that the birth of Computerized flat knitting machine makes whole sweater knit the speed of sheet processing, yet relatively supporting running-on processing link but still also is in the state of manual processing.Even therefore sweater factory buys a lot of Computerized flat knitting machines, but the running-on link does not catch up with a large problem that remains.

Binding-off machine is by the anter of woollen sweater, rear panel, cuff, sleeve, the bottom, neckline, left front unites by a seam on binding-off machine, the critical piece of binding-off machine is annular dials, the woollen sweater parts that need running-on are stacked and use tweezers to head into dials, rotation along with dials, the woollen sweater parts are sewn to together, the woollen sweater parts of having sewed up be arranged on dials one fixedly catch extrude dials, because the woollen sweater parts have very strong retractility, the woollen sweater parts that are pushed into dials often are in the shortest state, the woollen sweater of sewing up under this state is after dress, along with woollen sweater is stretched, the needle gage of sewing up is expansion greatly also, cause needle gage excessive, affect the stitching firmness of clothing and sew up aesthetic property.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of reducing sewing machine, and this reducing sewing machine can increase the sewing density of woollen sweater.

The technical scheme that its technical problem that solves the utility model adopts is:

This reducing sewing machine comprises by contact pin around the dials formed and stitching member, described stitching member is arranged on a side of described dials, the week of described dials upwards is provided with the catch of peeling off sweater, described contact pin is flexibly connected by can make progress in described dials footpath movable telescoping member and a described dials, described telescoping member is driven by a drive member, and described telescoping member is expanded through described stitching member the time.

As preferably, described stitching member is arranged on a retractor device, be used to coordinating the radial motion of described contact pin.

As preferably, described telescoping member is the piston formation that matches with cylinder body, described contact pin is arranged on described piston, one side of described cylinder body is provided with the blow vent that drives described piston, described piston has a spring be arranged in described cylinder body spacing, described drive member is that the arc that is arranged on stitching member one side of described dials drives cover, and described arc drives cover and is positioned at the described blow vent air-tight fit of sewing up member one side.

As preferably, be provided with the pressure control device of adjusting air pressure in described arc driving cover.

The utility model has the advantage of:

Utilize contact pin to be arranged on described telescoping member, can make the contact pin on described dials have different distances for described dials axle center, namely contact pin has different radiuses, thereby the sweater that makes to be positioned on described contact pin is expanded, thereby make the sweater sewing density closeer, sweater is sewed up more firm.

The accompanying drawing explanation

Fig. 1 is the plan structure schematic diagram of this reducing sewing machine;

Fig. 2 is the structural representation of the contact pin of this reducing sewing machine.

In figure 10, sweater; 100, dials; 200, contact pin; 300, sew up member; 310, retractor device; 400, drive member; 500, catch; 600, telescoping member; 610, blow vent; 620, spring; 630, piston.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated:

In the present embodiment, consult Fig. 1, this reducing sewing machine comprises by contact pin 200 around the dials 100 formed and stitching member 300, described stitching member 300 is arranged on a side of described dials 100, upwards be provided with the catch 500 of peeling off sweater 10 week of described dials 100, described contact pin 200 is flexibly connected with described dials 100 by can make progress in described dials 100 a footpaths movable telescoping member 600, described telescoping member 600 is driven by a drive member 400, and described telescoping member 600 is expansion through described stitching member 300 time.

Above-mentioned reducing sewing machine, described stitching member 300 are arranged on a retractor device 310, be used to coordinating the radial motion of described contact pin 200.

Consult Fig. 2, described telescoping member 600 is piston 630 formation that matches with cylinder body, described contact pin 200 is arranged on described piston 630, one side of described cylinder body is provided with the blow vent 610 that drives described piston 630, described piston 630 has a spring 620 be arranged in described cylinder body spacing, described drive member is that the arc that is arranged on stitching member 300 1 sides of described dials 100 drives cover, and described arc drives cover and is positioned at described blow vent 610 air-tight fit of sewing up member 300 1 sides.

Above-mentioned reducing sewing machine, described arc drives in cover and is provided with the pressure control device of adjusting air pressure, described pressure control device can make described arc driving cover have different pressure, thereby controls the stroke of described piston 630, reaches the purpose of controlling the density ratio.

The working method of above-mentioned reducing sewing machine:

Sweater 10 is pressed on the contact pin 200 of described dials 100, described contact pin 200 drives cover through the described arc of described stitching member 300 1 sides, described telescoping member 600 is expanded under the effect of air pressure, the radius at described contact pin 200 places is elongated, therefore, described sweater 10 is expanded, and now, after described stitching member 300, will make sweater 10 sewing densities closeer.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
