Description

Technical Field

[0001] This invention relates to the field of sock machine needle technology, and more specifically to a gripper device for transferring needles. Background Technology

[0002] The cylinder of a sock knitting machine is a key component that directly affects the proper functioning of the sinkers, needles, and jacquard needles (sock needles, sole plates, and jacquard plates). The cylinder, inner and outer sinker seats, and sinker covers are important parts of the sock knitting machine's needle train system. Their coordination with the loop-forming cams during the knitting motion is a major technical factor determining the quality of the sock fabric.

[0003] With the continuous improvement of international knitting technology, how to enrich the variety of socks and adapt them to different types of raw materials, while ensuring the quality of different knitted fabrics such as twill, mesh, jacquard, and wool terry fabrics, is a major technical issue for my country's sock machine manufacturing industry to participate in international competition and provide more advanced sock knitting equipment for the domestic sock industry.

The buffer seat 111 is connected to the inner wall of the transfer seat 1 via a buffer spring 13. A ball bearing 12 is provided between the rotating shaft 11 and the inner wall of the transfer seat 1. A central cross-shaped groove 14 is installed at the center of the bottom of the transfer seat 1, and two sets of side cross-shaped grooves 15 are installed on the bottom sides of the central cross-shaped groove 14. The central cross-shaped sliding groove 14 and the two sets of side cross-shaped sliding grooves 15 form a triangular fixing structure; the transfer seat 1 is installed on the upper part of the base 4, and the bottom of the base 4 is equipped with moving wheels 5; the upper part of the base 4 is provided with support plates 6 on both sides, and a hand frame 7 is provided on one side of the support plate 6; four sets of hydraulic telescopic frames 8 are provided on the upper part of the support plate 6, and a hydraulic pump 81 is provided on one side of the hydraulic telescopic frame 8; two sets of lifting top plates 9 are connected to the top of the hydraulic telescopic frame 8, and a first bracket 91 is provided on one side of one set of lifting top plates 9, and a second bracket 93 is provided on one side of the other set of lifting top plates 9.

[0032] In this embodiment, during the rotation of the rotating shaft 11, the buffer seat 111 and the buffer spring 13 provided in the middle of the rotating shaft 11 reduce the shaking during the use of the device. At the same time, the ball bearings 12 between the rotating shaft 11 and the inner wall of the transfer seat 1 reduce the friction of rotation, ensuring the overall stability of the device.

[0033] Example 2:

[0034] As attached Figure 2 To be continued Figure 4 As shown, specifically, a drive motor 92 is nested in the first bracket 91, and a lead screw 921 is connected to the output end of the drive motor 92. A sliding block 922 is sleeved on the lead screw 921. Three sets of cross fixing brackets 10 are fixedly installed on the sliding block 922. The three sets of cross fixing brackets 10 are staggered and form a triangular structure. A through groove 94 is provided on the upper part of the lifting top plate 9.

[0035] In this embodiment, during movement, the drive motor 92 starts, drives the lead screw 921 to rotate, the lead screw 921 drives the sliding block 922 to move forward, the sliding block 922 drives the three sets of cross fixing frames 10 to move forward, and the three sets of cross fixing frames 10 are inserted into the central cross groove 14 and the two sets of side cross grooves 15. Then, the device is lifted by four sets of hydraulic telescopic frames 8, which facilitates the movement of the device.

[0036] Working principle

[0037] When using this invention, during the rotation of the rotating shaft 11, the buffer seat 111 and the buffer spring 13 provided in the middle of the rotating shaft 11 reduce the shaking during the use of the device. At the same time, the ball bearings 12 between the rotating shaft 11 and the inner wall of the transfer seat 1 reduce the friction of rotation, ensuring the overall stability of the device.

[0038] When the device needs to be moved, the user pushes the scaffold 7 to move the base 4 to the upper part of the transfer seat 1. The four sets of hydraulic telescopic frames 8 are started simultaneously to raise the two sets of lifting top plates 9 to the same height as the transfer seat 1, and the three sets of cross fixing frames 10 are connected to the central cross slide 14 and the side cross slide 15.

[0039] Next, the drive motor 92 starts, and the drive motor 92 drives the lead screw 921 to rotate. The lead screw 921 drives the slide block 922 to move forward. The slide block 922 drives the three sets of cross fixing brackets 10 to move forward. The three sets of cross fixing brackets 10 are inserted into the central cross slide groove 14 and the two sets of side cross slide grooves 15. Then, the device is lifted by the four sets of hydraulic telescopic brackets 8, which facilitates the movement of the device.
