Description
Technical field
The present invention relates to a kind of threading mechanism automatically, be specifically related to the automatic needle-threading machine of a kind of eccentric wheel type.
Background technology
Needle-threading machine the elderly that conveniently eyesight is not good enough, the disabled disadvantaged group of trick design.
With regard to current family life analysis, the workmanship such as cross stitch, Nonwovens makes and firmly gets liking of women.But the line of variety classes, color is often replaced in these job requirements, so always wearing needlework obviously becomes a kind of loaded down with trivial details, bothersome work.Naturally automatic lacing machine effectively simple to operate can become their strong instrument.Certainly, batch machining production embroidery waits the factory of products more to need it to enhance productivity.
With regard to self-employed sewer, automatic lacing machine is their requisite instrument equally.Along with the degeneration of family's stitching process, individual sewer grows up gradually, small, automatic lacing machine easy to carry can become they " companion ".
For some special populations, the elderly as not good enough in eyesight, the handicapped disadvantaged group of trick, they under the help of this product, can realize " trying to make a match ", and can complete some daily requisite needleworks smoothly.
Summary of the invention
The object of the present invention is to provide the automatic needle-threading machine of a kind of eccentric wheel type, automatically to try to make a match, replace artificial threading.
Above-mentioned purpose is achieved by the following technical solution:
The automatic needle-threading machine of a kind of eccentric wheel type, comprise machine dish, motor, eccentric wheel, crochet hook fixed bar, fixed bar way block, suture needle fixed block, suture needle locating piece and travel switch, wherein, motor, travel switch, fixed bar way block and suture needle fixed block are fixed on machine dish; Described eccentric wheel is fixed on motor shaft, and eccentric wheel is connected by buckle structure from motor shaft farthest with crochet hook fixed bar one end, and described buckle structure and the below of crochet hook fixed bar junction are provided with the vertical touching tip pointing to travel switch; Described crochet hook fixed bar is slidably through fixed bar way block, and the crochet hook fixed bar other end is provided with crochet hook; The crochet hook hole that described suture needle fixed block is provided with suture needle hole and inserts for crochet hook, suture needle hole is perpendicular to machine dish, and crochet hook hole is located at and adapting position place, suture needle hole.
Crochet hook fixed bar of the present invention moves back and forth along the direction of fixed bar way block under eccentric rotarily driving, and when crochet hook fixed bar moves to suture needle fixed block, crochet hook passes the pin hole of suture needle along crochet hook hole; When crochet hook fixed bar deviates from suture needle fixed block, crochet hook hooks line through suture needle pin hole, and when touching tip and encountering travel switch, motor break-off, takes off the suture needle of putting on line, completes work of once threading a needle.
Further, also comprise the suture needle locating piece making suture needle pin hole aim at direction, crochet hook hole, described suture needle locating piece is slidably connected with the suture needle locating piece guide rod being fixed on suture needle fixed block side.Suture needle pin hole place is flat, is slided by suture needle locating piece along suture needle locating piece guide rod to suture needle direction, when suture needle locating piece arrives to suture needle pin hole place, can adjust the direction that suture needle pin hole is aimed at, make it face toward crochet hook hole, is convenient to crochet hook hole and inserts.
Beneficial effect of the present invention:
The automatic needle-threading machine of eccentric wheel type provided by the invention can be tried to make a match automatically, do not need manually the end of a thread to be inserted in tiny pin hole, be convenient to the not good enough the elderly of eyesight or the handicapped disadvantaged group of trick etc. and be engaged in needlework, the speed of trying to make a match can also be improved simultaneously, increase work efficiency.

Detailed description of the invention
Technical scheme of the present invention is described in detail below in conjunction with specific embodiment.
Fig. 1 is the automatic needle-threading machine front view of eccentric wheel type provided by the invention, Fig. 2 is top view, as can be seen from the figure, this needle-threading machine comprises machine dish 1, motor 2, eccentric wheel 3, crochet hook fixed bar 4, fixed bar way block 5, suture needle fixed block 8, suture needle locating piece 10 and travel switch 14, wherein, motor 2, travel switch 14, fixed bar way block 5 and suture needle fixed block 8 are fixed on machine dish 1 successively, arrange in yi word pattern.Eccentric wheel 3 is fixed on motor shaft, and eccentric wheel 3 is connected by buckle structure 6 from motor shaft farthest with crochet hook fixed bar 4 one end, and buckle structure 6 and the below of crochet hook fixed bar 4 junction are provided with the vertical touching tip 7 pointing to travel switch.Crochet hook fixed bar 4 is slidably through fixed bar way block 5, and crochet hook fixed bar 4 other end is provided with crochet hook 13.The crochet hook hole 15 that suture needle fixed block 8 is provided with suture needle hole 12 and inserts for crochet hook 13, suture needle hole 12 is perpendicular to machine dish 1, and crochet hook hole 15 is located at and adapting position place, suture needle hole 12.The automatic needle-threading machine of this eccentric wheel type also comprises the suture needle locating piece 10 making suture needle 9 pin hole aim at direction, crochet hook hole 15, and suture needle locating piece 10 is slidably connected with the suture needle locating piece guide rod 11 being fixed on suture needle fixed block 8 side.
Its operation principle is as follows: during original state, and eccentric wheel 3 and buckle structure 6 junction are away from suture needle fixed block 8, and crochet hook 13 does not insert the crochet hook hole 15 on suture needle fixed block 8.Now, suture needle 9 is inserted in suture needle hole 12, oppresses suture needle 9 pin hole to suture needle 9 direction slip suture needle locating piece 10, regulate suture needle 9 pin hole direction, make it aim at crochet hook hole 15, then suture needle locating piece 10 is back into initial position.Starting switch 17, motor 2 works, and when eccentric wheel 3 rotates to position shown in Fig. 1, crochet hook 13 passes suture needle 9 pin hole under the promotion of crochet hook fixed bar 4.Eccentric wheel 3 continues to rotate, and when rotating to original state, crochet hook 13 hooks line 16 and passes from suture needle pin 9 hole under the pulling of crochet hook fixed bar 4, meanwhile, touch tip 7 and touch travel switch 14, motor 2 break-off, take off the suture needle 9 of putting on line, complete work of once threading a needle.Before motor 2 again task, suture needle 9 be inserted in suture needle hole 12, adjustment suture needle 9 direction also puts line 16 well, starts work of next time threading a needle.
As can be seen from above-described embodiment, the automatic needle-threading machine of link-type provided by the invention can be tried to make a match automatically, do not need manually the end of a thread to be inserted in tiny pin hole, be convenient to the not good enough the elderly of eyesight or the handicapped disadvantaged group of trick etc. and be engaged in needlework, the speed of trying to make a match can also be improved simultaneously, increase work efficiency.
