[0002] The needle plates are installed on both sides of the needle bed of the computer flat knitting machine, and a number of parallel needle grooves are arranged on the needle plates. A yarn spacer and a yarn pressure plate are provided at the front end of each needle groove. The yarn pressure plate presses the old yarn loop of the knitting needle to cooperate with the knitting needle to complete the retraction, and the yarn spacer cooperates to complete the loop removal when the knitting needle descends. The yarn spacer and yarn pressure plate on the existing knitting needle plate are installed at the front end of the needle groove by steel wire. However, each yarn pressure plate and yarn spacer are installed in the same needle groove at the same time. This method makes the structure of the needle plate more complicated, and the disassembly and assembly are more cumbersome, which greatly increases the production and also greatly increases the opening width of the needle groove to make the needle distance between each knitting needle larger. Therefore, the woven fabric structure cannot be made denser. Utility Model Content

The sinkers are a pair and are inserted at intervals on the upper edge of the needle plate. The yarn spacer is arranged between the sinkers and inserted on the upper edge of the needle plate. A first limit strip is passed through the needle plate, one end of the sinker is movably connected to the first limit strip, and a second limit strip is passed through the upper edge of the needle plate, and an arc-shaped slot hole is provided at the other end of the sinker, and the arc-shaped slot hole is slidably matched with the first limit strip so that the sinker can swing up and down around the first limit strip.
[0005] Furthermore, the front end of the spacer piece is provided with a limiting groove, and the limiting groove cooperates with the first limiting strip.
[0006] Furthermore, a knitting needle is arranged on the rear side of the needle plate between the sinker and the yarn spacer, and the knitting needle is driven to rise or fall by the mountain plate.
[0007] Furthermore, a groove is provided at the front end of the yarn spacer, and the inner wall of the groove cooperates with the head end of the knitting needle to block the yarn.
[0008] Furthermore, the front end of the sinker is provided with a hook groove, so that the yarn can be pressed through the hook groove when the knitting needle is raised and withdrawn.
[0009] Furthermore, the front end of the sinker has a yarn blocking portion in front of the hook groove.

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0022] Reference Figure 1-Figure 3 As shown, a single-slot double-needle loop forming auxiliary device includes a needle plate 1, a sinker 2, and a yarn separator 3. The needle plate is provided with a plurality of first slots at intervals along the length direction, and a second slot is provided between any adjacent second slots. In this embodiment, the sinkers 2 are a pair and are inserted in the upper part of the first slot of the needle plate 1 at intervals, and are inserted in the first slot, and the yarn separator 3 is provided between the sinkers 2 and is inserted in the upper part of the second slot of the needle plate 1.
[0023] Knitting needles are arranged at the upper rear part of the needle plate 1 between the sinker 2 and the spacer 3. In the present embodiment, an insert is inserted in the first slot to form a single slot between the inserts, and a separator is inserted in the second slot to form a first needle slot and a second needle slot between the insert and the separator in the single slot, so that the knitting needles are slidably arranged in the first needle slot and the second needle slot respectively, thereby realizing a double-needle design in a single slot, making the weaving tighter.
[0024] Furthermore, a dovetail groove is provided on the upper part of the needle plate 1, wherein a first limit strip 15 is arranged in the dovetail groove of the needle plate, and an axial hole is provided at one end of the sinker 2 so that the first limit strip is passed through the axial hole of the sinker, and in addition, a groove is provided on the upper edge of the needle plate 1, in which a second limit strip 16 is fixedly arranged, and an arc-shaped slot hole 22 is provided at the other end of the sinker 2, and the arc-shaped slot hole 22 is slidably matched with the second limit strip 16, so that the sinker 2 can swing up and down at a certain angle around the first limit strip 15.
[0025] In addition, in the present embodiment, a guide plate is provided on the upper part of the needle plate 1 above the sinker 2, and guide grooves are provided on the guide plate at intervals along the length direction, and a sinker bell 24 cooperating with the sinker device of the sinker is provided on the top of the sinker 2, and the sinker bell of the sinker 2 is aligned with the guide groove to ensure that the sinker will not swing left and right during the swinging process, thereby greatly improving the stability of the sinker.
[0026] Furthermore, the front end of the sinker 2 has a hook groove 23, the front end of the sinker 2 has a yarn blocking portion 25 in front of the hook groove 23, and the front end of the sinker 2 has a yarn pushing portion 26 below the hook groove 23. When the knitting needle in the first needle groove or the second needle groove rises to withdraw the loop, the sinker is driven to swing forward through the signal device, so that the hook groove 23 of the sinker presses the old thread loop on the knitting needle, helping the knitting needle to smoothly complete the withdrawal of the loop, and then the signal component of the mountain plate links the sinker 3 to reset , so as not to hinder the knitting needle from forming a loop, thereby preventing the old coil from rising with the knitting needle, and when the knitting needle descends and bends the yarn to form a loop, the yarn of the old coil rests on the yarn pushing portion 26 of the sinker 3, and while the knitting needle pulls down the loop, the sinker is linked to the signal component to drive the sinker to swing forward, and the old coil is pushed by the yarn pushing portion 26 of the sinker 3, thereby assisting the knitting needle to enlarge the coil, so that the knitting needle can successfully complete the weaving into a loop, thereby speeding up the looping speed of the coil and preventing the coil from being too tight when the knitting needle is forming a loop.
[0027] In this embodiment, a second axial hole is provided at the rear end of the spacer piece 3 so that the first limiting strip is passed through the axial hole of the spacer piece 3, and a limiting groove 32 is provided at the front end of the spacer piece 3. The limiting groove 32 cooperates with the second limiting strip 16 to avoid the spacer piece 4 from swinging, thereby greatly improving the stability of the spacer piece 4.
[0028] Furthermore, in the traditional single-slot double-needle needle plate, according to the knitting requirements, there is a situation where one of the knitting needles needs to participate in knitting, while the other knitting needle does not. In this situation, when the knitting needle involved in knitting descends to form a loop, the yarn in the loop is easy to run into the needle hook of the other knitting needle, thereby affecting the knitting work.
[0029] Therefore, in this embodiment, a slot 33 is provided at the front end of the spacer 3. When the knitting needle 21 in the first needle groove 13 hooks the coil and descends to form a loop, if the knitting needle 21 in the second needle groove 14 does not participate in weaving, the inner wall of the slot of the spacer 3 and the knitting needle in the second needle groove are used to cooperate to block the yarn of the coil, so as to prevent the yarn of the coil from running into the needle hook of another knitting needle 21 under the pull of the knitting needle, thereby ensuring the stability of weaving and reducing the defective rate of the woven fabric.
[0030] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
