Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figure 1 to Figure 3, this use in sewing machine automatic threading apparatus comprises support 1, support 1 is provided with the self-threading axle 3 and needle bar 2 that be arranged in parallel, support 1 is from top to bottom provided with the first mount pad 1a successively, second mount pad 1b and the 3rd mount pad 1c, needle bar 2 runs through the first mount pad 1a and the 3rd mount pad 1c and can move axially, self-threading axle 3 runs through the second mount pad 1b and the 3rd mount pad 1c and can move axially, in needle bar 2 lower end, suture needle 5 is installed, self-threading axle 3 is socketed with drive link 4 and is fixed with threading needle 6 in self-threading axle 3 lower end, be provided with between self-threading axle 3 and drive link 4 and self-threading axle 3 circumference can be made to rotate and make threading needle 6 penetrate rotating mechanism to suture needle 5 pinprick place.
Further, from top to bottom once mounting limited location seat 7 and drive rod 8 on needle bar 2, limit base 7 and drive rod 8 are between the first mount pad 1a and the 3rd mount pad 1c, and rotating mechanism is resisted against on limit base 7.Drive rod 8 is for being connected with the driving mechanism in Sewing machines, moving axially of needle bar 2 is controlled by driving mechanism, simultaneously by limit base 7 and drive rod 8 come together determine needle bar 2 move axially time stroke, when limit base 7 is resisted against on the first mount pad 1a, needle bar 2 moves on stopping, when drive rod 8 is resisted against on the 3rd mount pad 1c, needle bar 2 stops moving down; Because self-threading axle 3 is slidably connected on support 1, in unresisted situation, self-threading axle 3 and drive link 4 can axially move down under self gravitation effect, and when rotating mechanism is resisted against limit base 7, self-threading axle 3 moves down the limited seat 7 of trend and hindered, and self-threading axle 3 can move up together along with needle bar 2 under the drive of limit base 7; The object simultaneously driving self-threading axle 3 to move up by limit base 7 is that self-threading axle 3 moves up and down together with needle bar 2 when Sewing machines works, thus does not affect the normal work of Sewing machines.
Further, rotating mechanism comprises and is socketed in back-moving spring 9 on self-threading axle 3 and radial direction and inserts solid on self-threading axle 3 and the bearing pin 11 be resisted against on limit base 7, back-moving spring 9 one end is resisted against on drive link 4, the other end is resisted against on bearing pin 11, drive link 4 offers the pilot hole 4a be obliquely installed, and bearing pin 11 outer end is plugged in pilot hole 4a and bearing pin 11 can move up and down along pilot hole 4a.When self-threading axle 3 is slack, when pulling drive link 4 to make it move axially downwards, bearing pin 11 moves along pilot hole 4a, thus self-threading axle 3 circumference is rotated.Drive link 4 and self-threading axle 3 are linked together by back-moving spring 9, in unresisted situation, drive link 4 and self-threading axle 3 can synchronously move axially up and down.
Further, limit base 7 is in " Contraband " font and limit base 7 bottom faces self-threading axle 3 has horizontally outward extended to form stop part 7a, and bearing pin 11 the inner can be resisted against on this stop part 7a.Because needle bar 2 is when moving up, be resisted against after on the first mount pad 1a by limit base 7 upper end and just stop moving, and self-threading axle 3 move up by limit base 7 promote cause, therefore stop part 7a is set in limit base 7 lower end, makes bearing pin 11 can not touch the first mount pad 1a.
Further, limit base 7 is connected on needle bar 2 by screw, due to limit base 7 be resisted against on the first mount pad 1a time, needle bar 2 moves on stopping, when drive rod 8 is resisted against on the 3rd mount pad 1c, needle bar 2 stops moving down, and drive rod 8 is connected with driving mechanism, therefore the position of drive rod 8 on needle bar 2 is fixing, when needing the stroke adjusting needle bar 2, only need adjust limit base 7 and be arranged on position on needle bar 2, concrete operations mode makes limit base 7 can move axially along needle bar 2 for first being unscrewed by screw, after limit base 7 moves into place, again tightening screw.
Further, needle bar 2 is socketed with buffer spring 10, buffer spring 10 one end is resisted against on limit base 7, the other end is resisted against on drive rod 8, when limit base 7 lost efficacy with the fixed relationship of needle bar 2, limit base 7 was when needle bar 2 rose, and buffer spring 10 can play cushioning effect, and isolated limit base 7 contacts with the direct of drive rod 8, limit base 7 is avoided to cause damage to drive rod 8 and affect the work of whole Sewing machines.
Further, threading needle 6 radial direction is arranged on self-threading axle 3 and the syringe needle of threading needle 6 curves inwardly, because threading needle 6 is the pinpricks that just can pass through to suture needle 5 under the circumference of self-threading axle 3 is rotated, therefore curved shape in being become by the needle design of threading needle 6, makes threading needle 6 rotate centered by the axle center of self-threading axle 3 under the drive of dynamic threading axle and pass the pinprick of suture needle 5.
Further, threading needle 6 syringe needle is made up of two clamping part 6a of bifurcation design, spacing between two lateral walls of two clamping part 6a is less than the aperture of suture needle 5 pinprick, threading needle 6 syringe needle bifurcation design is become two clamping part 6a, upper thread is interted between two clamping part 6a, when threading needle 6 is through suture needle 5, upper thread is promoted also thereupon through the pinprick of suture needle 5 by threading needle 6.
Further, handle 4b is provided with in drive link 4 lower end, when drive link 4 and self-threading axle 3 axially move down until when bearing pin 11 on self-threading axle 3 is resisted against on limit base 7 under self gravitation effect, by pressing handle 4b, one downward power is applied to drive link 4, thus make drive link 4 can continue to move down, and self-threading axle 3 can not move down along with drive link 4 by limit base 7 restriction, this structure is convenient for people to pull drive link 4.
When using this use in sewing machine automatic threading apparatus, when interting the fracture of the upper thread on suture needle 5 pinprick, when needing again threading, needle bar 2 moves up under the drive of driving mechanism until limit base 7 is touched to the first mount pad 1a, and now needle bar 2 stops mobile; Because the bearing pin 11 on self-threading axle 3 is resisted against on limit base 7 all the time, the also drive self-threading axle 3 moved up at needle bar 2 and drive link 4 move up together, when being resisted against the stop part 7a place on limit base 7 when bearing pin 11, self-threading axle 3 and drive link 4 also slack, threading needle 6 now on self-threading axle 3 is in same level with suture needle 5 pinprick center, and upper thread is between threading needle 6 syringe needle two clamping part 6a; Then drive link 4 is pulled to make it continue to move down, bearing pin 11 is moved along the pilot hole 4a on drive link 4, thus drive self-threading axle 3 circumference to rotate, now threading needle 6 also rotates thereupon and passes the pinprick of suture needle 5, and upper thread is promoted by threading needle 6 and passes the pinprick of suture needle 5 thereupon; Best, unclamp drive link 4, under the effect of back-moving spring 9, drive link 4 moves up, and bearing pin 11 is moved along the pilot hole 4a on drive link 4, thus makes drive link 4 and self-threading axle 3 return to original position, and threading work completes.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
