[0023] The driving mechanism includes a motor 9, and three transmission rollers 11 are rotatably arranged on one side of the mounting plate 10, the three transmission rollers 11 are arranged in a triangular shape, a belt 12 is transmissionally arranged between the three transmission rollers 11, and a clamping rod 13 is fixedly arranged on the side wall of the belt 12. The motor 9 is fixedly installed on the bottom plate 1, and the output shaft of the motor 9 is coaxially and fixedly connected with one of the transmission rollers 11. Two guide grooves are formed in the vertical direction on the side of the mounting plate 10 where the transmission rollers 11 are arranged, two guide blocks are arranged on the moving plate 14, and the guide blocks are in limited sliding cooperation with the guide grooves in a one-to-one correspondence. In addition, a sliding groove is formed in the horizontal direction in the moving plate 14, and the clamping rod 13 is limitedly and slidably arranged in the sliding groove.

[0024] Start the motor 9, the output shaft of the motor 9 drives the belt 12 to rotate through the transmission roller 11, the belt 12 drives the moving plate 14 to slide in the vertical direction through the clamping rod 13, in this process, the clamping rod 13 slides in the sliding groove, and the guide block slides in the guide groove.

[0025] As shown in the figure, Figure 1 The transmission member includes a plurality of teeth 17, the plurality of teeth 17 are fixedly arranged on the belt 12, a part of the plurality of teeth 17 is arranged in the transmission direction of the belt 12, and the clamping rod 13 is located at the middle position of the plurality of teeth 17. A gear 18 is rotatably arranged on the mounting plate 10, the gear 18 is in contact and meshing transmission with the plurality of teeth 17. A rotating ring 20 is rotatably arranged on the top of the bottom plate 1, a plurality of tooth blocks 2 are fixedly arranged on the top of the rotating ring 20, the plurality of tooth blocks 2 are distributed in a circumferential array along the central axis of the rotating ring 20, and the tooth blocks 2 are in meshing transmission with the gear 18. In addition, a transmission belt 4 is transmissionally arranged between the rotating ring 20 and the round plate 3.

[0026] A C-shaped snap-fit ​​connector 15 is fixedly installed on one side of the movable plate 14. The snap-fit ​​connector 15 is engaged with the plate 6 via an elastic snap-fit ​​component. The elastic snap-fit ​​component includes a snap post 8, which is vertically slidably positioned within the plate 6. One end of the snap post 8 is smoothly curved and slides through the plate 6. A spring 7 is provided between the snap post 8 and the plate 6. One end of the spring 7 is fixedly connected to the snap post 8, and the other end is fixedly connected to the plate 6. A slot 16 is formed within the snap-fit ​​connector 15, which is adapted to the curved end of the snap post 8, and the two are slidably engaged.

[0027] Working principle: In the initial state, both material rods 5 are fully covered with sealing rings, with the bottom sealing ring in contact with the top of the clamping plate 6. For example... Figure 1 As shown, at this time, the lever 13 is located in the middle of the slide groove, and the teeth 17 and gear 18 are in a meshing state. The number of teeth 17 on the left and right sides of the lever 13 is equal.

[0028] like Figure 1 As shown, during use, the motor 9 is started, and the output shaft of the motor 9 drives the belt 12 to rotate through the transmission roller 11. The rotation of the belt 12 causes the clamping rod 13 to slide to the right in the slide groove. During the process of the clamping rod 13 sliding from the middle position of the slide groove to the rightmost position of the slide groove, the teeth 17 on the left side of the clamping rod 13 mesh with the gear 18, causing the tooth block 2 to drive the rotating ring 20 to rotate, thereby driving the circular plate 3 to rotate through the transmission belt 4, and then driving the material rod 5 on the circular plate 3 to rotate.

[0029] When the lever 13 slides to the far right of the groove, the tooth 17 on the left side of the lever 13 disengages from the gear 18, and the circular plate 3 rotates exactly 90 degrees counterclockwise. At this time, Figure 1 The card plate 6, which is located above the base plate 1, slides into the inside of the card connector 15. The card post 8 on the card plate 6 will be locked in the card slot 16 under the elastic action of the spring 7, thereby completing the transmission and locking of the card connector 15 and the card plate 6.

[0030] Subsequently, the clamping rod 13 drives the moving plate 14 to slide upwards, thereby causing the clamping plate 6 to move upwards by the thickness of a sealing ring through the clamping connector 15. This results in one sealing ring moving upwards by the thickness of a sealing ring, i.e., gradually dragging the sealing rings upwards. At this time, the external gripping device set above the material rod 5 can grab the sealing rings on the material rod 5 in sequence. When the clamping rod 13 drives the moving plate 14 to slide to the highest point, the sealing rings on the material rod 5 have been grabbed. After the clamping rod 13 passes the highest point, with the transmission of the belt 12, the clamping rod 13 will drive the moving plate 14 to slide downwards, causing the clamping connector 15 to drive the clamping plate 6 back to the initial state. During the above process, the clamping rod 13 will slide to the left in the groove.

[0031] When the clamping rod 13 slides to the leftmost position, the teeth 17 on the right side of the clamping rod 13 are just in contact with the gear 18, and as the movement continues, when the clamping rod 13 moves to the middle position again, the circular plate 3 is just rotated counterclockwise by 90 degrees. When moving from the middle position to the rightmost position, the circular plate 3 is rotated counterclockwise by 90 degrees again, at this time, the clamping plate 6 on the other material rod 5 is just in transmission clamping cooperation with the clamping joint 15, so as to carry out the feeding of the sealing ring on the other material rod 5, and the material rod 5 after feeding can carry out the feeding of the sealing ring.

[0032] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
