Description
Technical field
The utility model is about a kind of Sewing machines feed mechanism improvement, especially possesses the feeding function of general sewing program and the function of independent feeding.
Background technology
The sewing of Sewing machines moves, and utilizes major impetus assembly drive transmission device, to drive upward the axle part and the lower shaft spare of Sewing machines, wherein goes up the shank on the axle part drive eccentric ratio device, is converted to moving up and down of suture needle and needlework; Lower shaft spare is also made circular motion via crochet hook under the power transmission shaft drive or is swung, and makes down the bottom line of crochet hook and last needlework form line ring structure; Also drive the feeding structure simultaneously via cam, eccentric ratio, make it produce intermittent movement, so cooperate the car pin to sew up and down once, cloth is fed certain-length forward, promptly be complete single pin sighting slit mark, quick acting just can reach the purpose of multilayer cloth stitching continuously.
As above-mentioned Sewing machines feed mechanism, mainly can be divided into wheeled two kinds of flat tooth-like and knuckle-tooth, wherein flat tooth-like feed mechanism is arranged at the suture needle below usually, is to drive with cam, eccentric shaft and connecting rod, intermittent movement about before and after producing cooperates foot device to reach the feeding function; And the wheeled feed mechanism of knuckle-tooth is arranged at the suture needle rear usually, is to utilize camshaft and swing arm, transfers to by circular motion swinging up and down, and drives Knucle-gear via the unidirectional drive assembly again and produces intermittent circular motion, reaches the feeding function.
Though sewing type and technology constantly change innovation, but promptly as can be known by above-mentioned explanation, at all events plant feed mechanism, all can't finish feeding separately, must cooperate the sewing action synchronously, as being combined into example with sewing selvedge or many creases, often need to rely on the familiar skill of operating personnel, cooperate and help the seam cloth guider, can intermittently sew forms, cause quality to be difficult for controlling, therefore if cloth can be sent in advance a segment distance to make its stable back recurrence seam, just can improve the sewing quality operating efficiency is promoted, for these reasons, known feed mechanism function still has deficiency, so need further improvement.
Summary of the invention
This creation is the improvement of a kind of Sewing machines feed mechanism, except the interlock feeding function that possesses known sewing program, when also possessing not sewing, the function of feeding separately, with two kinds of functions altogether structure in same group of device, be the main purpose of this creation.
This creation is provided with several fixed blocks, fixed block fitted bearing external member is provided with first power transmission shaft, second power transmission shaft and the 3rd power transmission shaft, fixedly connected first gear of first power transmission shaft wherein, and first power transmission shaft is provided with swing arm and connects eccentric ratio, be provided with first unilateral bearing between this swing arm and first power transmission shaft, and fixedly connected second gear of second power transmission shaft, utilize the axle part of Sewing machines below major impetus to drive eccentric ratio drive swing arm, cooperate first unilateral bearing to drive first power transmission shaft, make first gear drive, second gear and second power transmission shaft, utilize transmission component directly to drive and go up wheel and lower whorl, to finish the feeding action of general sewing program; And for reaching above-mentioned main purpose, this is created in same group of device and is provided with the 3rd power transmission shaft, one end connects second Power Component, the other end is provided with the 3rd gear, and be provided with the 3rd unilateral bearing between the 3rd gear and the 3rd power transmission shaft, when needs are fed cloth separately, with control system major impetus being switched to second Power Component starts, make second Power Component drive the 3rd power transmission shaft, allow the 3rd gear rotate, drive first gear and second gear drive, first power transmission shaft, second power transmission shaft, power is conveyed to wheel and lower whorl by transmission component, makes wheel and lower whorl can finish the function of drawing the work feed material separately, allow this creation except the interlock feeding function that possesses general known sewing program, also have independent feeding function concurrently, and then promote crudy.
Description of drawings
Fig. 1: be the stereogram of this creation.
Fig. 2: be the three-dimensional system diagram of this creation.
Fig. 3: be the three-dimensional system diagram of this creation.
The specific embodiment
See also as shown in Figures 1 to 3, this creation is a kind of Sewing machines feed mechanism improvement, Sewing machines platform 1 is provided with several fixed blocks 11, fixed block 11 fitted bearing external members are provided with first power transmission shaft 21, second power transmission shaft 31 and the 3rd power transmission shaft 41, wherein first power transmission shaft, 21 fixedly connected first gears 2, and first power transmission shaft 21 are provided with swing arm 211, and swing arm 211 connects eccentric ratio 212, be provided with first unilateral bearing 22 between this swing arm 211 and first power transmission shaft 21, the other end is provided with second unilateral bearing 23; Second power transmission shaft, 31 fixedly connected second gears 3; The 3rd power transmission shaft 41 1 ends connect second Power Component 40, and the other end is provided with the 3rd gear 4, and are provided with the 3rd unilateral bearing 42 between the 3rd gear 4 and the 3rd power transmission shaft 41; With reference to as shown in Figures 2 and 3, one of first power transmission shaft 21 and second power transmission shaft 31 end is connected with transmission component 5, and transmission component 5 be connected to respectively take turns 51 and lower whorl 52 in the suture needle rear.
The feeding action of general sewing program, system utilizes the axle part of Sewing machines below major impetus to drive eccentric ratio 212 and drives swing arm 211, cooperate first unilateral bearing 22 to drive first power transmission shaft 21, the intermittent continuous motion that allows first gear 2 produce single direction, drive second gear 3 and second power transmission shafts 31 with first gear 2 again, make first power transmission shaft 21 and second power transmission shaft 31 can utilize transmission component 5 directly to drive to go up wheel 51 and lower whorl 52 is finished the feeding action; When needs are fed cloth separately, with control system major impetus being switched to second Power Component 40 starts, make second Power Component 40 drive the 3rd power transmission shaft 41, cooperate the 3rd unilateral bearing 42 to allow the 3rd gear 4 rotate, and then drive first gear 2 and second gear 3 drives first power transmission shaft, 21 second power transmission shafts 31, power is conveyed to wheel 51 and lower whorl 52 via transmission component 5, makes wheel 51 and lower whorl 52 can finish the function of drawing the work feed material separately.
The Sewing machines feed mechanism improvement of this creation, between the 3rd gear 4 and the 3rd power transmission shaft 41, be provided with the 3rd unilateral bearing 42, when so second Power Component 40 starts, can pass on power to the three gears 4, and when the switching major impetus is carried out general sewing program, also can utilize the effect of the 3rd unilateral bearing 42 to make the 3rd gear 4 form the rotation of free state, and do not influence the 3rd power transmission shaft 41 and second Power Component 40, the major impetus and second Power Component 40 can not influenced each other, therefore this creation can be total to structure in same device with two kinds of functions, make it can improve the sewing procedure, promote the sewing quality, increase operating efficiency.
