Description

Technical Field

[0001] The utility model relates to the field of flat knitting machines, in particular to a sinker used for a knitting machine. Background Art

[0002] The sinker is an important component in a knitting machine. During the process of knitting garments, looping and needle transfer are indispensable knitting actions of the garments. The sinker is an important component that presses the loop and helps to form the loop. The existing sinker has a positioning hole for the wire rotating shaft to pass through. However, the wire rotating shaft is connected to the sinker by passing through the positioning hole. Therefore, when replacing individual damaged sinkers, the entire wire rotating shaft must be pulled out. After the replacement is completed, the wire rotating shaft needs to be reinstalled. After multiple installation and disassembly operations, the wire rotating shaft is easily worn, and other intact sinkers are easily damaged during the threading process. At the same time, the installation and disassembly process is cumbersome and complicated, time-consuming and laborious, and the cost is increased. Utility Model Content

[0026] Reference Figure 1 and Figure 2 A sinker for a knitting machine comprises a body 1, a positioning hole 11 for a steel wire rotating shaft to pass through is provided at the bottom of the body 1, an elliptical hole 112 communicating with the positioning hole 11 is further provided at the upper edge of the positioning hole 11, the elliptical hole 112 can provide a variable stretching space for elastic deformation, and an opening 111 communicating with the positioning hole 11 is further provided at the lower edge of the positioning hole 11;

[0027] The width of the opening 111 is gradually reduced from the tail to the direction close to the positioning hole 11, so that the width of the part of the opening 111 close to the positioning hole 11 is smaller than the diameter of the positioning hole 11, and the width of the lower end notch of the opening 111 away from the positioning hole 11 is larger than the diameter of the steel wire rotating shaft. When subjected to external pressure, the two ends of the opening 111 will produce elastic deformation of relative displacement. The cooperation between the opening 111 and the positioning hole 11 can make the main body 1 snap onto the steel wire rotating shaft, which is convenient for the installation and disassembly of the main body 1 and saves manpower.

[0028] Based on the above structure, an opening 111 is provided at the lower end of the positioning hole 11, which is connected and gradually decreases from the tail to the direction close to the positioning hole 11. During installation, it is only necessary to align the notch at the lower end of the opening 11 that is larger than the diameter of the wire rotating shaft with the wire rotating shaft, and apply downward pressure to the sinker, which will cause elastic deformation of relative displacement at both ends of the opening 111, and the elliptical hole 112 provided at the upper edge of the positioning hole 11 provides a variable stretching space for the elastic deformation, so that the wire rotating shaft can easily slide into the positioning hole 11 along the lower end notch of the opening 111, so that the positioning hole 11 is connected to the wire rotating shaft, and It has the function of relative rotation with it. When replacing, lifting the sinker will make the wire rotating shaft contact with the notch at the upper end of the opening 111 to generate a reaction force, so that the notch of the opening 111 close to the positioning hole 11 will produce the same elastic deformation as during installation, thereby quickly pulling the damaged sinker out from the wire rotating shaft, realizing quick and convenient installation or removal of the sinker, and solving the problem that the user needs to disassemble the entire wire rotating shaft when installing or removing the sinker, which is easy to cause wear of the wire rotating shaft, and other intact sinkers are easily damaged during the threading process, which not only wastes work time but also increases production costs.

[0029] In one embodiment, referring to Figure 1 and Figure 2The main body 1 is provided with an elastic sheet 12, a sheet heel 13 and a wire pressing portion 14. The elastic sheet 12 is located between the sheet heel 13 and the positioning hole 11. The elastic sheet 12 is arranged in an S-shaped structure. The S-shaped design can make the elastic sheet 12 have good elasticity, so that it is easier to deform after being subjected to external force, so that the pressure of the sinker on the coil is more flexible and not easy to break the coil. The elastic sheet 12 includes a pressure-bearing portion 121, a transmission portion 122 and an elastic portion 123. The elastic portion 123 is connected to the main body 1, and the end of the elastic portion 123 away from the main body 1 passes through the transmission portion 122 is connected to the pressure-receiving part 121. When the pressure-receiving part 121 is pressed, the pressure is transmitted to the elastic part 123 through the transmission part 122, and then the elastic deformation is generated by the elasticity of the elastic part 123, so that a pressure can be provided to the main body 1 for a long time, so that the presser foot 141 can maintain a flexible pressure for a long time when pressing the yarn, and the phenomenon that the sinker widely used in the flat knitting machine on the market uses rigid pressure to press the coil and causes the coil to be broken to form a defective product will not occur, thereby achieving long-term pressing of the knitted fabric and preventing the abnormal phenomenon of needle biting during local knitting;

[0030] Under the action of power, the heel 13 enables the main body 1 to rotate in a circle along the axis of the steel wire rotating shaft. The wire pressing part 14 is arranged on the side of the main body 1 away from the elastic sheet 12. The wire pressing part 14 includes a presser foot 141 and a limiting slot 142. The presser foot 141 is used to press the coil, and the limiting slot 142 is used to limit the sinker from excessively rotating forward. The presser foot 141 is arranged on the edge of the side of the main body 1 away from the positioning hole 11, and the limiting slot 142 is located between the presser foot 141 and the elastic sheet 12. When the sinker rotates toward the front side around the steel wire rotating shaft under the action of power to press down the yarn, the limiting slot 142 is stuck in the corresponding limiting steel wire, so that the rotation angle of the sinker can be controlled, and the sinker is prevented from excessively rotating forward. The height of the loop can be effectively controlled, and a uniform and uniform coil of the same size can be formed at a certain loop density, thereby improving the quality of the woven fabric.

[0031] In one embodiment, referring to Figure 1 The main body 1, the elastic sheet 12, the sheet heel 13 and the pressing line portion 14 are an integrated structure, and are made of stainless steel sheet metal parts in the prior art, and are corrosion-resistant, wear-resistant, aging-resistant, and durable.

[0032] In one embodiment, referring to Figure 1 The edges of the body 1, the elastic sheet 12, the heel 13 and the pressing line 14 are all set to be rounded. The use of the rounded corner process can reduce the stress at the mutation surface, increase the critical point of fracture and deformation of the material, and the rounded corner setting also makes the sinker have better smooth performance during use.

[0033] In one embodiment, referring to Figure 1 and Figure 2The concave walls of the positioning hole 11 and the limiting notch 142 are both arranged in an arc shape. The arc-shaped arrangement can reduce the stress at the mutation surface and increase the critical point of fracture and deformation of the material.

[0034] In one embodiment, referring to Figure 3 The thicknesses of the body 1, the elastic sheet 12, the sheet butt 13 and the pressing line portion 14 are consistent, which has good versatility and higher strength against deformation and wear, greatly increases the service life of the sinker and reduces the use cost of the sinker.
