Description

Technical Field

[0001] This utility model belongs to the technical field of sock machine equipment, and specifically relates to an elastic band pressing device for sock machines. Background Technology

[0002] Elastic yarn is a type of elastic yarn used in the knitting process of socks. Existing elastic yarns mainly rely on limiting holes to roughly define their position, lacking a control device with clamping force, making it impossible to accurately control the elasticity and precise position of the elastic yarn. How to achieve elastic adjustment of the elastic yarn during the sock knitting process is the subject of research for those skilled in the art. Utility Model Content

[0003] This invention provides a simple structure, adjustable elasticity of elastic thread, and reasonable positional accuracy control for sock machines using elastic thread pressing devices.

[0004] A sock knitting machine elastic band pressing device includes a base with a horizontal pull rod groove and a pressing plate mounting slope. A pull rod is installed in the horizontal pull rod groove. A pressing plate is installed on the pressing plate mounting slope. The pressing plate and the pull rod cooperate to form an angle for clamping the elastic band. The distance between the pressing plate and the pull rod controls the clamping force of the elastic band. The position of the pull rod in the horizontal pull rod groove is controlled by a pull rod positioning device. This sock knitting machine elastic band pressing device forms a clamping force on the elastic band by the angle formed by the cooperation of the pressing plate and the pull rod. By controlling the distance between the pressing plate and the pull rod, the clamping force of the elastic band can be adjusted, achieving adjustable elasticity of the elastic band.

[0005] The aforementioned pull rod positioning device includes a lower limiting groove located on the base, a limiting block located on the lower side of the pull rod engaging with the upper side of the lower limiting groove, and an upper limiting groove located on the upper side of the pull rod engaging with a limiting screw. The limiting screw is located within the first mounting hole on the pressure plate mounting slope. The limiting screw achieves upper limit positioning of the upper limiting groove by threading into the first mounting hole, while the lower limiting groove engages with the limiting block located on the lower side of the pull rod, ultimately achieving the function of positioning the pull rod.

[0006] One end of the pull rod extends out of the horizontal pull rod groove and is equipped with a hook. The other end of the pull rod also extends out of the horizontal pull rod groove and is equipped with a spring positioning post and a flange. A spring is installed between the flange and the limiting surface of the base, and the spring is sleeved on the spring positioning post. The hook provides initial positioning for the elastic band, while the spring controls the horizontal position of the pull rod. In the locked state, the spring has an axial preload, which improves the stability of the clamping plate and the pull rod in holding the elastic band.

[0007] The limiting screw passes through the second mounting hole and the first mounting hole on the pressure plate to fix the pressure plate and the base, improving the stability of the pressure plate connection. The pressure plate is made of metal.

[0008] The horizontal tie rod groove is provided with a cover plate on its side. The cover plate is connected to the base through the first connecting hole to prevent dust and impurities from entering the horizontal tie rod groove and to extend the service life of the elastic thread pressing device for sock machines.

[0009] The base has a second connecting hole on its side, and the second connecting hole is connected to the sock machine mounting frame through a screw.

[0010] This invention uses a pressure plate and a pull rod to form an angle for clamping the elastic cord. The distance between the pressure plate and the pull rod controls the clamping force of the elastic cord to achieve the pressing of the elastic cord, preventing the elastic cord from drifting randomly and adjusting the elasticity of the elastic cord.

[0016] The following is in conjunction with the appendix Figure 1-4 The specific implementation method further illustrates the technical solution of this patent.

[0017] A sock knitting machine elastic band pressing device includes a base 3, the base 3 having a horizontal pull rod groove 8 and a pressing plate mounting slope 13, and a pull rod 2 installed in the horizontal pull rod groove 8. A pressing plate 1 is installed on the pressing plate mounting slope 13, and the pressing plate 1 and the pull rod 2 cooperate to form an angle for clamping the elastic band. The distance between the pressing plate 1 and the pull rod 2 controls the clamping force of the elastic band.

[0018] As a preferred structural feature, the position of the pull rod 2 within the horizontal pull rod groove 8 is controlled by a pull rod positioning device. The pull rod positioning device includes a lower limiting groove 12 located on the base 3, with a limiting block 15 located on the lower side of the pull rod 2 engaging on the upper side of the lower limiting groove 12. An upper limiting groove 16 is provided on the upper side of the pull rod 2, engaging with a limiting screw located within the first mounting hole 7 of the pressure plate mounting slope 13. The pull rod positioning device controls the distance between the pressure plate 1 and the pull rod 2, thereby adjusting the angle gap between the pressure plate 1 and the pull rod 2 that holds the elastic band, and thus controlling the elastic tension of the elastic band during the sock knitting process.

[0019] To further improve the control performance of the elastic band's position and elasticity, one end of the pull rod 2 extends out of the horizontal pull rod groove 8 and is equipped with a hook 21. The other end of the pull rod 2 also extends out of the horizontal pull rod groove 8 and is equipped with a spring positioning post 17 and a flange 18. A spring 5 is provided between the flange 18 and the limiting surface 19 of the base 3, and the spring 5 is sleeved on the spring positioning post 17. The limiting screw passes through the second mounting hole 6 and the first mounting hole 7 on the pressure plate 1 to fix the pressure plate 1 and the base 3.

[0020] To extend the service life of the elastic band pressing device for sock machines, a cover plate 4 is provided on the side of the horizontal pull rod groove 8. The cover plate 4 is connected to the base 3 through the first connecting hole 10 to prevent dust from entering the horizontal pull rod groove 8. A second connecting hole 9 is provided on the side of the base 3, and the second connecting hole 9 is connected to the sock machine mounting bracket 20 through a screw.
