Description

Technical Field

[0001] This utility model relates to the field of sock machines, and specifically to a transmission mechanism for a sock machine gripping device. Background Technology

[0002] Sock knitting machines can be classified according to the needle bed type, needle type, and number of cylinders (beds). The basic structure of a circular knitting machine includes a cylindrical cylinder with several needles arranged on its outer circumference. The movement of these needles weaves the yarn into loops, eventually forming a complete sock. A steel ring surrounds the upper part of the cylinder, and various components are arranged along this ring. These components work in conjunction with the needles or yarn as needed, acting on the yarn to perform various knitting movements. Additionally, various components that coordinate with the needle movements are located in the middle and lower outer periphery of the cylinder.

[0003] In this knitting process, the knitting into tubes and the end closing are usually done separately. Therefore, a gripping device is needed to transfer the fabric from the tubular knitting part to the toe closing part. For example, CN101970739B discloses a "pickup device for picking up tubular knitted items from a circular knitting machine for socks or similar items and for conveying the tubular items to a unit suitable for additional processing on the items." Such a pickup device generally needs to have both "lifting" and "rotating" functions. However, in the prior art, the lifting shaft and rotating shaft for these two functions are not on the same axis, which can easily cause vibration during transmission and reduce transmission accuracy.

[0004] Therefore, the inventors conducted further research and developed a transmission mechanism for a sock-grabbing device, which led to this invention. Utility Model Content

[0005] The purpose of this invention is to provide a transmission mechanism for a sock-making machine gripping device, which can improve transmission accuracy and make transmission more stable.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A transmission mechanism for a sock-grabbing device includes

[0008] The gripping component is mounted on the lifting shaft sleeve, which is fitted over the main shaft and can slide up and down and rotate around the main shaft. The main shaft is fixed on the base.

[0009] A rotating shaft is installed inside the main shaft. One end of the rotating shaft is driven to rotate by a rotary motor, and the other end is equipped with a lead screw nut seat, which is linked to the lifting shaft sleeve.

[0010] The lead screw nut seat is also equipped with a lifting lead screw, which is located in the lead screw connecting seat, and the bottom of the lead screw connecting seat is connected to the lifting bushing.

[0011] With the above settings, the rotation and lifting of the gripping component are both centered on the main shaft, making the transmission more stable and preventing the rotation and lifting from interfering with each other.

[0012] Furthermore, the lifting screw is linked to the lifting motor via a coupling.

[0013] Furthermore, the rotating shaft is linked to a rotating worm gear via a rotating turbine, and the rotating worm gear is linked to a rotating motor.

[0014] Furthermore, the lifting motor linked to the lifting screw is located above the lifting bushing, while the rotary motor linked to the rotary shaft is located below the lifting bushing.

[0015] Since the upgraded lead screw and lifting motor can be set in the same straight line direction as the main shaft, setting them at the top will not affect the center of gravity of the entire transmission mechanism. However, the rotary motor is set in a direction that is relatively perpendicular to the main shaft, so setting it at the bottom can better stabilize the entire transmission mechanism.

[0016] Furthermore, the lifting screw drives the screw nut seat to rise and fall via the screw nut.

[0017] Furthermore, a guide shaft is provided on one side of the lead screw nut seat, and a lifting bushing is also provided on the guide shaft.

[0018] The rotation of the gripping component is driven by the guide shaft.

[0019] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0020] This makes the transmission of the sock machine's gripping device more stable and less prone to vibration; the entire lifting and rotating axis is aligned, resulting in higher transmission precision; and its structure is more compact and simpler compared to existing technologies.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , Figure 2 As shown, a transmission mechanism for a sock-making machine gripping device mainly includes a lifting motor 1, a lifting screw 4, a gripping assembly 9, a base 10, a main shaft 12, a lifting bushing, a rotating shaft 13, a rotating worm gear, and a rotating motor 17. When the lifting and rotation of the gripping assembly 9 share the same axis, its stability is significantly improved. Specifically:

[0027] A vertical main shaft 12 is fixedly mounted on a base 10. A lifting sleeve 11 is fitted over the main shaft 12, and a rotating shaft 13 is installed inside the main shaft 12. A rotating turbine 14 is installed at the bottom of the rotating shaft 13, and the rotating turbine 14 is located in a turbine auxiliary base 18. A rotating worm gear 15 is also horizontally installed in the turbine auxiliary base 18. The rotating worm gear 15 is linked to a rotary motor 17 via a coupling 16. A lead screw nut seat 8 is installed at the upper end of the rotating shaft 13. The lead screw nut seat 8 can rotate with the rotating shaft 13. A vertical guide shaft 7 passes through one side of the lead screw nut seat 8 and is also connected to the lifting sleeve 11. The gripping component 9 is mounted on the lifting sleeve 11. Therefore, the rotary motor 17 can ultimately drive the gripping component 9 to rotate.

[0028] The lifting motor 1, located above the entire mechanism, is mounted on a motor base 2. It is linked to the lifting screw 4 via a coupling 4 located in the motor base 2. The motor base 2 is also connected to the screw connecting seat 3, which in turn is connected to the lifting bushing 11. The lifting screw 4 is located inside the screw connecting seat 3, and a screw nut 6 is fitted on the lifting screw 4. The screw nut 6 can move up and down relative to the lifting screw 4. The aforementioned screw nut seat 8 is located outside the screw nut 6. Therefore, the power generated by the lifting motor 1 is ultimately transmitted to the lifting bushing 11 through the lifting screw 4, enabling it to move up and down.

[0029] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
