Description

Disk sewing machine

Technical field

The utility model relates to sewing machine technical fields, more particularly, to a kind of disk sewing machine.

Background technique

Disk sewing machine is a kind of common sewing device of clothes processing industry, is especially suitable for the suture of knitwear, therefore Also known as disk sweater sewing machine, the disks of two relative rotations are arranged on disk sewing machine, and the pivot center of disk is vertical Setting.The course of work of disk sewing machine: first the knitting cloth that two layers is superimposed together simultaneously hang over disk needle thorn outer end Be pre-positioned, so latter two hang with knitting cloth disk relatively rotate, when the sweater on two disks turn to it is opposite Jumper clip is sutured, to make two between two disks by the way that the suturing mechanism above disk is arranged in when position Knitting cloth suture is completed.

But such disk sewing machine, in suture, knitting cloth must reach the upper surface of disk, facilitate sewing machine Structure passes through two layers of knitting cloth, but can generate knitting cloth perpendicular to cloth during suturing mechanism pierces through knitting cloth The power on surface is expected, to make knitting cloth tilt to side, to cause the seam of suture uneven.

Utility model content

The purpose of the utility model is to provide a kind of disk sewing machines, have the effect that can suture the neat seam of comparison Fruit.

The foregoing invention purpose of the utility model has the technical scheme that

A kind of disk sewing machine, the disk including rack and two rotation connections on the rack, two disks relatively rotate And pivot center is vertical, two disks are in same unison, and the position between the disk is used for while clipping two layers of needle Woven fabric material, the position that disk top knitting cloth closes up are provided with guide pad, and guide pad is fixed in the rack above disk, leads Guide groove is offered to the lower surface of block, guide groove is the rectangular channel that Open Side Down, and the length direction of guide groove is parallel to disk The tangential direction of guide pad is set.

By using above-mentioned technical proposal, in use, knitting cloth is hung on disk, needle is provided on two disks Woven fabric material, knitting cloth is in two disks with disk rotational, and two disks relatively rotate, and knitting cloth is turning to phase When between two adjacent disks, the knitting cloth on two disks is opposite, and the lower surface for being located at guide pad above disk is opened It is just corresponding with closing up for knitting cloth equipped with guide groove, so that guide groove clips knitting cloth, then the process sutured In, guide groove is jointly fixed knitting cloth with disk, to reduce knitting cloth by the seam perpendicular to knitting cloth Laterally offset when resultant force, so that the seam of suture is more neat.

The utility model is further arranged to: it is import that the guide groove, which is located at the relatively close one end of two disks, End, the other end are outlet end, and input end is arranged to splayed and the biggish opening of splayed backwards to guide groove.

By using above-mentioned technical proposal, the position that guide groove is located at input end opens up into splayed, splay import End, knitting cloth can be squeezed when entering from input end to middle part, to keep it more preferable to the clamping effect of knitting cloth.

The utility model is further arranged to: the top surface that the guide groove is located at input end is provided with transition face, transition face One end close to guide groove input end is upturned.

By using above-mentioned technical proposal, guide groove be located at input end top surface setting transition face, transition face be located at into The one end at mouthful end is upturned, so that cloth be made to be downwardly against in guide groove, knitting cloth can be made to be easier to enter and lead Into slot.

The utility model is further arranged to: the ratio of the length of the guide groove and width is 2.5~3.5.

By using above-mentioned technical proposal, the lenth ratio control of guide groove is 2.5 to 3.5, the length of such guide groove It spends long, the length of guide groove can be made longer, keep it stronger to the fixation of cloth.

The utility model is further arranged to: the top surface of the guide groove is provided with adjustable plate, and adjustable plate is parallel to guiding The top surface of slot, regulating device is connected on adjustable plate, and the adjusting direction of regulating device is vertical direction.

By using above-mentioned technical proposal, adjustable plate is arranged in the top surface of guide groove, by regulating device to the height of adjustable plate Degree is adjusted, and the height for the knitting cloth for entering guide groove can be made to be adjusted, to make the suture width of its seam It is adjusted.

The utility model is further arranged to: the regulating device includes the screw thread for adjusting screw and being provided on guide pad Hole, threaded hole are vertically arranged, and threaded hole is through-hole, and the lower end of threaded hole extends in guide groove；The adjusting screw with Threaded hole is threadedly engaged, and adjusts screw lower end with adjustable plate rotation connection and pivot center is vertically arranged.

By using above-mentioned technical proposal, the threaded hole adjusted on screw and guide pad cooperates, and adjusts screw in threaded hole When interior rotation, adjusting screw lower end, which is rotatably connected on adjustable plate, to be moved up and down, so that the height of adjustable plate be made to be adjusted.

The utility model is further arranged to: the upper surface for adjusting screw offers flat recess.

By using above-mentioned technical proposal, the upper surface for adjusting screw opens up flat recess, personnel can be easy to use to rotate Adjust screw.

The utility model is further arranged to: the radius of two disks is equal, and a disk is active movement, Another disk is passive movement.

By using above-mentioned technical proposal, the radius of two disks is equal, and drives another circle by a disk Disk rotation, can be avoided two disks velocity of rotation it is unequal caused by the movement velocity of knitting cloth differ, to make to connect It stitches more neat.

In conclusion the advantageous effects of the utility model are as follows:

1. the adjacent position of two disks, which is located at, clips knitting cloth, and the top of disk by two disks of setting It is provided with guide pad, the guide groove for pressing from both sides knitting cloth is offered on guide pad, so that the upper and lower of knitting cloth is clipped, from And reduce the offset of knitting cloth, keep seam more neat；

2. be arranged to splayed by the input end in guide groove, to make the cloth entered in the input end of guide groove more Be easy to clip into guide groove, and the width of guide groove can be arranged it is smaller, it is bigger for the clamping force of knitting cloth；

3. the height of adjustable plate can be adjusted, to make looped fabric by being provided with adjustable plate on the top surface of guide groove The suture width of material is adjusted.
