Description
Technical field
The utility model relates to technical field of sewing equipment, used rotating shuttle in particularly a kind of shoes mending machine.
Background technology
Rotating shuttle is the important composition part of Sewing machines, and is in sewing device, the most general with the Sewing machines that lock-type chain stitch is sewed up.These Sewing machines great majority are to adopt rotating shuttle, catch on wire loop with its spur, enlarge wire loop simultaneously, and the guiding wire loop constitutes lock-type chain stitch around crossing shuttle.Usually behind eedle rising certain distance, the spur of rotating shuttle bed begins to collude the inlet wire ring, and spur catches on the wire loop continued and rotates, and when wire loop was sent to rotating shuttle frame guide rail mouth, wire loop was caught on by shuttle frame separated time hook, and at this moment eedle should be by rising 2 millimeter on the limit inferior position.Separated time hook on the rotating shuttle frame should wire loop soon near the time, make the wire loop end leave the back that the time moves on to guide rail and go, separated time hook and eedle kinematic axis line angle are about 50 °; Locate to catch on wire loop for 45 ° by shuttle race spur housing convex surface top, be rotated further, collude on the separated time hook end of wire loop; For wire loop is successfully slided on the surface of shuttle frame, the hypotenuse of wire guide plate afterbody is outwards pushed the end of a thread of wire loop aside, and the rear portion of wire loop; Colluded by shuttle frame separated time hook on one side; Slide to shuttle frame bottom, in this moment, eedle withdraws from rotary shuttle mechanism.Because it is very smooth that the shuttle frame is crossed the line place, wire loop is successfully skidded off from shuttle frame bottom, in the time of making spur turn over 180 °, thread take-up tension lever rises; Sending the remainder separated time that gets off to collect before the thread take-up tension lever, spur catches on wire loop and continues rotation, and the wire loop first half is below wire guide plate; Behind 45 ° of inclined-planes of housing convex surface, the wire guide plate edge that is moving progressively exceeds the shuttle frame; Outwards to push the first half wire loop aside. latter half of wire loop is caught on by shuttle frame separated time hook, and separating before and after the wire loop, last wire loop front-back overlapped the shuttle frame; Be enclosed within the centre to bottom line,, form stitching through thread take-up tension lever tension wire loop.The operation cycle of rotary shuttle mechanism is the stage of catching on wire loop and enlarging wire loop between 203 °～312 °, is that to withdraw from 0 °～180 ° of stages from the shuttle sleeve breach be idle stroke to pin between 312 °～320 °.Last axle one changes, and rotating shuttle two changes, and generation effect when second changes.The principle and the shuttle of rotating shuttle formation stitching are basic identical, but the process of its formation stitching has different with method again with shuttle: rotating shuttle is to rotatablely move as constant angular velocity, and shuttle is to do the variable speed oscillating traverse motion; In eedle once pumps (one week of main axis rotation), the rotating shuttle constant angular velocity rotated for two weeks, and shuttle swings back and forth once; Rotating shuttle is that the rotating shuttle frame is fixing, and the rotating shuttle bed rotates, and it is to catch on wire loop by the shuttle race point, carries out separated time by rotating shuttle frame hook, makes it walk around shuttle sleeve and shuttle frame bottom, top, from the sub-emaciated face line formation of rotating shuttle wrench wire loop.
The rotating shuttle of common shoes mending machine causes rotating shuttle operation difficulty because structure is complicated, and it is not smooth to make that upper thread slides when off-line, is unfavorable for carrying out fast of sewing work.
The utility model content
For addressing the above problem, the utility model provides a kind of shoes mending machine rotating shuttle.
The technical scheme that the utility model adopts is,
A kind of shoes mending machine rotating shuttle includes the shuttle body, is provided with peg or spindle in the shuttle body, and the peg or spindle surface is wound with bottom line, also comprises the shuttle frame, and shuttle is set up in the workbench of shoes mending machine, and the shuttle body places on this shuttle frame,
The external side of said shuttle has depressed part, and said shuttle frame has the semi-surrounding sidewall, and this semi-surrounding sidewall is stuck in the said depressed part, makes the shuttle frame drive the shuttle body and in workbench, rotates;
The external side of said shuttle also has outwardly directed spur, and spur is positioned at depressed part one side, has wire hole in the shuttle body, and wire hole leads to shuttle body top from shuttle body inwall, and bottom line passes from this wire hole.
Further, the external wall of said shuttle is provided with a cell body, has the through hole that is communicated with shuttle body inwall in the cell body, and the outlet of said wire hole is positioned at shuttle body top, and the import of wire hole is communicated with this cell body, and bottom line passes said through hole and gets in the wire hole;
Said shuttle body bottom was provided with linear slit, and this is crossed linear slit and runs through the shuttle inside and outside, and is communicated with said through hole, can make things convenient for the threading work of bottom line, during use, placed the shuttle body inner peg or spindle, and bottom line gets into and passes wire hole again the through hole and get final product from crossing linear slit.
In addition, the bottom of said shuttle body has spacing ring, and said peg or spindle bottom surface contacts with this spacing ring, and the cover plate that cooperating platform upper surface is provided with makes the range of movement of peg or spindle be limited in shuttle body inside;
Have the slit that supplies upper thread to pass through between said semi-surrounding sidewall and the said depressed part, make the smooth off-line of upper thread, stranded with bottom line.
The advantage of the utility model is that this rotating shuttle is simple in structure, and operation is smooth, can increase substantially sewing efficiency, reduces noise.
