Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1-8 shown: The sinker bar device with a quick needle-clearing triangle includes a front and rear arranged motherboard 100 and a slide plate 200. There are three sets of sinker systems 300 with the same design on the motherboard 100. The sinker system 300 is composed of two sinker triangles 310, a yarn pressing triangle 320, a reset triangle 330 and a set of zero-clearing mechanisms 340. Among them, the zero-clearing mechanism 340, sinker triangle 310, yarn pressing triangle 320, and reset triangle 330 are arranged in sequence from the inside to the outside in the sinker system 300. When the slide plate 200 slides left and right, the two sinker triangles 310 and the yarn pressing triangle 320 can be driven by it to move relatively up and down on the motherboard 100, and the zero-clearing mechanism 340 can be deformed into a guiding path connecting the two sinker triangles 310, so that after the sinker leaves the high sinker triangle 310, it immediately starts to retract along the guiding path, thus avoiding interference with the movement of another set of sinker bar devices of the machine head.

[0028] Furthermore, the above-mentioned reset triangle 330 functions to reset the sinker in the sinker system 300, and it can be directly fixed on the motherboard 100. Of course, for different sinker systems 300 on the motherboard 100, if their reset triangles 330 are adjacent to each other, an integral molding design is allowed between the reset triangles 330.

[0029] Further, the above-mentioned zero-clearing mechanism 340 includes a movable zero-clearing triangle 341 and a fixed zero-clearing triangle 342. The fixed zero-clearing triangle 342 is directly fixed on the motherboard 100. The movable zero-clearing triangle 341 is arranged on both sides of the fixed zero-clearing triangle 342 respectively, and is correspondingly called the left zero-clearing triangle and the right zero-clearing triangle. The left zero-clearing triangle and the right zero-clearing triangle can be dragged by the Xinke triangle 310 to move relatively up and down on the motherboard 100, so as to jointly form the guiding path connecting the two Xinke triangles 310 with the fixed zero-clearing triangle 342.

[0030] Specifically, the above two Xinke triangles 310 are sequentially called the left Xinke triangle and the right Xinke triangle, and the two yarn-pressing triangles 320 are sequentially called the left yarn-pressing triangle and the right yarn-pressing triangle. Among them, the two Xinke triangles 310 are used to correspondingly drive the above-mentioned left zero-clearing triangle and right zero-clearing triangle to move; as Figure 8 shown, the first pin shaft 3411 and the second pin shaft 3412 are inserted up and down on the movable zero-clearing triangle 341 itself. The first pin shaft 3411 and the second pin shaft 3412 are correspondingly inserted into the motherboard pin slot 101 and the Xinke pin slot 311 opened on the motherboard 100 and the Xinke triangle 310. When the Xinke triangle 310 moves up and down driven by the slide plate 200, it can drag the movable zero-clearing triangle 341 to move up and down on the motherboard 100 by means of the first pin shaft 3411 and the second pin shaft 3412.

[0031] Specifically, due to the relative movement between the movable zero-clearing triangle 341 and the Xinke triangle 310, a slideway 312 allowing the movable zero-clearing triangle 341 to move is formed on the Xinke triangle 310 itself, and the above-mentioned Xinke pin slot 311 is opened on the slideway 312.

[0032] Further, the above-mentioned slide plate 200 is formed with a guide groove 201. The guide groove 201 adopts an M-shaped design combining an upper groove area 211 and a lower groove area 221, and is transitioned with an arc structure at the connection. The upper groove area 211 and the lower groove area 221 match the extended and retracted states of the sinker. As Figures 4-7 shown, a Xinke slider 350 and a yarn-pressing slider 360 are correspondingly installed in the Xinke longitudinal groove 102 and the yarn-pressing longitudinal groove 103 opened on the above-mentioned motherboard 100. The front ends of the Xinke slider 350 and the yarn-pressing slider 360 are combined with the Xinke triangle 310 and the yarn-pressing triangle 320, and the rear ends are combined with the Xinke bottom plate 351 and the yarn-pressing bottom plate 361. The Xinke guide wheel 352 and the yarn-pressing guide wheel 362 installed on the back of the Xinke bottom plate 351 and the yarn-pressing bottom plate 361 are jointly located in the guide groove 201 of the slide plate 200; when the slide plate 200 is driven by a driving element to slide left and right, the cooperation between the guide groove 201 and the Xinke guide wheel 352 and the yarn-pressing guide wheel 362 can make the Xinke triangle 310 and the yarn-pressing triangle 320 move up and down correspondingly, and the movement of the Xinke triangle 310 can drag the above-mentioned movable zero-clearing triangle 341.

[0033] Furthermore, the installation method of the above-mentioned slide plate 200 is realized by the front and rear combined fixing seat 400 and the slide plate seat 500; Figure 5 As shown, the back side of the skateboard seat 500 is formed with protruding portions 501 on the upper and lower sides, and a transverse limiting groove 502 is formed between the two protruding portions 501. The skateboard 200 is installed behind the skateboard seat 500 through the limiting groove 502. The protruding portion 501 above the skateboard seat 500 can directly pass through the lower groove area 221 in the middle of the guide groove 201 of the skateboard 200. The skateboard seat 500 is assembled with the fixing seat 400 through the upper and lower protruding portions 501, and after being fastened to each other by means of fasteners, they can be enclosed together to form a clamp, and the skateboard 200 can only slide left and right in the clamp, and will not detach outward.

[0034] Furthermore, a rack 600 is fixed to the back of the above-mentioned skateboard 200, and the rack 600 cooperates with the driving element to pull the skateboard 200 to slide left and right. The driving element can be a cylinder, a motor or other similar components (not shown in the figure).

[0035] The operating principle of this design is roughly the same as that of the existing sinker bar device. Both of them control the extension and retraction of the sinker to make it participate in / not participate in the corresponding yarn pressing work. When the sinker leaves the sinker triangle at the high point of this design, it can use the guide path formed by the zeroing mechanism to directly start to retract during the displacement, thereby avoiding interference with another set of sinker bar devices on the machine head as much as possible.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
