[0029] See also Figure 6The buffer assembly 64 in this embodiment includes a first damper 641 that is symmetrically connected to the lower end of the plug-in shaft 62 for preliminary buffering support, a connecting arm 642 that is correspondingly installed at the lower end of the first damper 641 on both sides for connection and cooperation, a slider 643 that is fastened to the lower end of the connecting arm 642 on both sides, a guide rod 644 that is laterally inserted into the interior of the sliders 643 on both sides and fastened to the interior of the shell 61, a compression spring 645 that is correspondingly installed on both sides of the outer side of the guide rod 644 and connected to the outside of the sliders 643 on both sides for elastic buffering support, and a second damper 646 that is laterally connected to the lower end of the slider 643 for secondary damping and buffering cooperation.

[0030] Specifically, the first damper 641, the connecting arm 642, the slider 643, the compression spring 645 and the second damper 646 are all symmetrically arranged along the left and right lower end of the plug-in shaft 62, and the connecting arm 642 is tilted and fixed along the upper end of the slider 643 to ensure that the connecting arm 642 is in a stable connection state; the second damper 646 and the compression spring 645 are arranged relative to each other in the upper and lower parts, and the overall structure of the second damper 646 is consistent with the second damper 646, ensuring that the second damper 646 and the compression spring 645 cooperate with each other to achieve efficient buffering and shock absorption.

[0031] Here's how it works:

[0032] When the large disc gear body 2 is sleeved onto the outside of the large disc body 1, the ball 3 provided inside the large disc gear body 2 will slide and embed with the outer side of the upper end of the large disc body 1. At the same time, the bottom of the large disc gear body 2 will come into contact with the pad 4 provided on the outer side of the upper end of the large disc body 1, thereby realizing the rapid formation of the large disc mechanism state. In this way, under the support and sliding cooperation of the ball 3 and the pad 4, the large disc gear body 2 can realize stable rotation transmission along the outer side of the large disc body 1, thereby ensuring the stability of subsequent knitting activities.

[0033] In order to ensure that the large disc gear body 2 is in a stable state when rotating along the outside of the large disc body 1 and reduce the occurrence of rotation and tilt, a support assembly 63 is provided on the four sides of the outer end of the large disc body 1. That is, when the large disc gear body 2 is sleeved to the outside of the large disc body 1, the plug-in shaft 62 provided inside the support device 6 will be vertically inserted into the lower end of the large disc gear body 2 to achieve preliminary support on the four sides of the bottom of the large disc gear body 2. Then, the rotating rod 631 provided inside the support assembly 63 can be rotated to achieve the rotation of the rotating rod 63. The external threaded end of the movable bar 632 is connected to the lateral transmission. As the movable bar 632 moves horizontally, the first rack 633 connected to the top of the movable bar 632 will move horizontally in the same direction, and the gear 634 engaged with the upper end of the first rack 633 can rotate to achieve the reverse lateral transmission of the second rack 635 engaged at the top. In this way, the connecting frame 636 connected to the outer side of the first rack 633 and the second rack 635 can move to the left or right side of the upper end of the plug-in shaft 62 to achieve the middle rotation of the connecting roller 6 The outer portion of the roller 637 is pushed out of the main body 37, thereby making the outer portion of the roller 637 contact with the inner wall of the lower end of the large plate gear body 2, realizing lateral support and auxiliary rotation transmission when the large plate gear body 2 rotates, thereby improving the smoothness of rotation. Secondly, when the connecting frames 636 on both sides move in opposite directions, a group of first racks 633, gears 634 and second racks 635 installed on the upper ends of the connecting frames 636 on both sides can be driven at the same time to ensure the stability of the simultaneous lateral movement of the connecting frames 636 on both sides, and are correspondingly plugged into the first racks 633 The limiting shaft 638 on the outside of the second rack 635 can also realize auxiliary support cooperation to ensure stable transverse transmission of the first rack 633 and the second rack 635. Therefore, after the rollers 637 provided inside the four-side support device 6 complete the contact movement with the inner wall of the lower end of the large plate gear body 2, it can ensure that the large plate gear body 2 as a whole can be limited in position during the subsequent rotation process, maintain a smooth rotation state, and reduce the occurrence of tilting rotation, thereby achieving the advantages of auxiliary flat support and rotation cooperation of the large plate gear body 2;

[0034] At the same time, during the rotation of the large disc gear body 2, the rotation stability can be further improved. A buffer assembly 64 is provided at the lower end of the plug-in shaft 62, that is, the vibration generated during the rotation of the large disc gear body 2 will be initially squeezed and buffered by the first dampers 641 provided on both sides of the bottom of the plug-in shaft 62. Then, the first damper 641 will push the connecting arm 642 to make the slider 643 move laterally along the outside of the guide rod 644, thereby realizing the squeezing of the compression spring 645 installed on the left or right side of the guide rod 644, so that the compression spring 645 realizes elastic buffering cooperation. At the same time, the second damper 646 relatively laterally installed at the lower end of the slider 643 can be synchronously compressed to realize damping and buffering cooperation again, thereby significantly improving the shock absorption and buffering performance, so that the large disc gear body 2 can be guaranteed to be in a stable rotation state when it rotates, thereby achieving the advantages of efficient buffering and shock absorbing support of the large disc gear body 2 and reducing rotational vibration.

[0035] The present invention provides a large plate mechanism of a numerically controlled circular knitting machine, which is provided with a support device 6, that is, a plug-in shaft 62, which can initially achieve flat support cooperation, and under the threaded transmission of the rotating rod 631 and the movable bar 632 provided inside the supporting assembly 63, the first rack 633, the gear 634 and the second rack 635 can achieve synchronous opposite transverse transmission, so that the connecting frames 636 provided on both sides can push out the rollers 637 to contact with the lower end of the large plate gear body 2, so as to achieve flat support and subsequent flat rotation of the large plate gear body 2, thereby achieving the advantages of auxiliary flat support and rotation cooperation of the large plate gear body 2, and a buffer assembly 64 is provided, that is, under the cooperation of the first damper 641, preliminary shock absorption and buffering can be achieved, and under the transverse movement of the slider 643, the compression spring 645 and the second damper 646 can cooperate with each other to further improve the shock absorption and buffering performance, thereby achieving the advantages of efficient buffering and shock absorption support of the large plate gear body 2 and reducing rotational vibration.
