Description

Technical Field

[0001] The utility model relates to the technical field of weaving equipment, and more specifically to an elastic sinker with double pressure lines. Background Art

[0002] A computerized flat knitting machine is a double-needle plate latch needle weft knitting machine. Its cam mechanism acts like a set of flat cams. The needle's foot enters the cam's groove, moving the cam, forcing the needle to rise and fall rhythmically within the needle slot of the needle plate. Through the action of the needle hook and latch, the yarn is woven into a knitted fabric. As the needle rises, the yarn loop gradually exits the hook, opening the latch and withdrawing it to hang on the needle bar. As the needle descends, the hook grabs the newly placed yarn and pulls it into a coil, while the existing coil escapes the hook. The new coil passes through the old coil and connects in series. Numerous strings of knitted yarns are connected to form the knitted fabric.

[0003] Currently, the elastic sinkers used in most knitting machines have significant design limitations. Due to insufficient downward pressure on the elastic sinker, the sinker cannot be pressed down deeply enough, failing to meet market knitting requirements. Furthermore, due to inappropriate design, the sinker is prone to jamming and other problems during the downward pressure process.

[0004] In view of the above-mentioned deficiencies of the existing elastic sinkers, the applicant has adhered to the spirit of research innovation and continuous improvement, combined with production practice, and used professional and scientific methods to propose a practical solution, and therefore filed this application. Summary of the Invention

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides an elastic sinker with double pressure lines. The elastic sinker is provided with multiple inclined surfaces, so that the sliding process is smoother.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a double-line-pressing elastic sinker, the elastic sinker consists of three parts: a pushing member, a yarn pressing member, and an elastic arm. The lower front end of the pushing member is connected to the yarn pressing member, the elastic arm is connected to the connection between the yarn pressing member and the pushing member, the top of the pushing member is provided with an upwardly extending sinker heel, the bottom of the pushing member is provided with a limiting groove, the front end of the limiting groove is a slope, a straight slot hole is provided in the middle of the pushing member, a sliding protrusion is provided at the end of the elastic arm, the front end of the sliding protrusion is a circular arc slope, the front end of the yarn pressing member is provided with an inner groove yarn storage groove, the front side of the yarn storage groove is the first line-pressing part, and the rear side of the yarn storage groove is the second line-pressing part.

[0007] Specifically, the end of the elastic arm is formed by two-stage bending. The end of the elastic arm is first bent downward and then bent upward. This design can increase the elastic force of the elastic arm itself and increase the pressure of the wire pressing.

[0008] Specifically, the elastic sinker is divided into an upper thick portion and a lower thin portion, the pushing member and the elastic arm are the upper thick portion of the elastic sinker, and the yarn pressing member is the lower thin portion of the elastic sinker.

[0009] Specifically, the pushing member and the elastic arm are made of metal material and are integrally formed, and the yarn pressing member is arranged on one side of the pushing member, so that the structure is more stable.

[0010] Specifically, an L-shaped air-avoiding groove is provided below the end of the pushing member, and the air-avoiding groove corresponds to the steel wire for installing the limit on the needle plate device.

[0011] Specifically, a limiting inclined surface is provided in front of the air-avoiding groove so that the end thereof can be smoothly stuck on the steel wire, and the structural design is more reasonable.

[0012] Specifically, the yarn pressing member includes a yarn storage groove and a limiting notch, and the limiting notch is located behind the yarn storage groove.

[0013] Compared with the prior art, the beneficial effects are:

[0014] 1. The front end of the limit groove 1 of the pusher is an inclined surface, which can ensure that the pusher will not get stuck during the sliding of the sedimentation piece. Compared with the traditional right-angle or rounded-angle design, the cylinder on the needle pressing block can slide more smoothly on its inclined surface, thereby ensuring that the sedimentation piece slides down, so that the yarn storage groove presses the yarn with a lower degree of pressure, thereby increasing the number of knitting rows;

[0015] 2. The elastic arm adopts a two-stage bending design, bending downward and then upward, which increases the elastic force of the elastic arm itself, provides sufficient downward pressure on the sinker, and increases the downward pressure amplitude; a circular arc slope is added to the front end of the sliding bump at the end of the elastic arm. The circular arc slope can effectively avoid getting stuck and make it smoother when sliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate the embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will understand that some well-known structures and their descriptions may be omitted from the drawings. The positional relationships depicted in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0022] like Figures 1 to 5 The bottom of the pushing member 1 is provided with a limiting groove 11, and the front end of the limiting groove 11 is an inclined surface 12. A straight slot hole 13 is provided in the middle of the pushing member 1, and a sliding protrusion 31 is provided at the end of the elastic arm 3. The front end of the sliding protrusion 31 is a circular arc inclined surface 32. The front end of the yarn pressing member 2 is provided with a yarn storage groove 21 with an inner groove, and the front side of the yarn storage groove 21 is a first pressing part 22, and the rear side of the yarn storage groove 21 is a second pressing part 23. The end of the elastic arm 3 is a bent portion 33 formed by two-stage bending. The end of the elastic arm 3 is first bent downward and then bent upward, and its end extends downward as a whole.

[0023] The yarn storage groove 21 holds the yarn through a U-shaped groove. The first pressing part 22 can press the coil higher, and the second pressing part 23 increases the pressing surface and can press the coil deeper. In fact, the number of shoveling needle rows increases by more than 50.

[0024] In the above embodiment, the elastic sinker is divided into an upper thick portion 11 and a lower thin portion 12. The pusher 1 and the elastic arm 3 constitute the upper thick portion 11 of the elastic sinker, and the yarn pressing member 2 constitutes the lower thin portion 12 of the elastic sinker. The pusher 1 and the elastic arm 3 are integrally formed of metal, making the overall structure more robust. The yarn pressing member 2 is disposed on one side of the pusher 1.

[0025] In the above scheme, an L-shaped air avoidance groove 14 is provided below the end of the pushing member 1, and the air avoidance groove 14 corresponds to the steel wire for installing the limiting position on the needle plate device. A limiting inclined surface 15 is provided in front of the air avoidance groove 14, and the yarn pressing member 2 includes a yarn storage groove 21 and a limiting groove 24, and the limiting groove 24 is located behind the yarn storage groove 21.

[0026] When installing the elastic sinker, install the sinker between the two knitting needle pressure blocks 4. The two knitting needle pressure blocks 4 are supported by a cylinder. The cylinder is divided into a sliding cylinder 41 and a limiting cylinder 42. The limiting cylinder 42 corresponds to the limiting groove 11 and moves back and forth along the limiting groove 11 and its front end inclined surface 12. The sliding cylinder 41 is set in the straight slot hole 13 and moves in the straight slot hole 13, thereby controlling the lateral displacement distance of the elastic sinker.

[0027] During sliding, the elastic sinker of the present application drives its displacement through the woven mountain plate, and moves back and forth through the sinker heel 16 of the elastic sinker, and the limiting cylinder 42 gradually enters the limiting groove 11. At this time, the elastic sinker applies an upward force through the elastic arm 3, and the sliding protrusion 31 of the elastic arm 3 moves on the lower insert, causing the front end of the elastic sinker to swing downward, and the front end of the yarn pressing piece 2 can press down the yarn 5 in the coil.

[0028] Obviously, the above embodiments of the present invention are merely examples for the purpose of clarifying the present invention and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications based on the above description are possible, such as the use of two-system or three-system lead plate systems. It is not necessary and impossible to provide an exhaustive list of all implementation methods. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
