A first motor 29 is fixedly mounted on one end of the rotating seat 14, and an output end of the first motor 29 is fixedly connected to one end of the worm 28. By starting the first motor 29, the worm 28 and the worm wheel 27 drive the rotating shaft 23 to rotate under the output of the first motor 29. The rotating rotating shaft 23 drives the six connecting pins 26 to rotate synchronously along the inner wall of the transmission groove 25 in an arc trajectory under the rotation of the six arc-shaped transmission grooves 25, thereby driving the six engaging links 22 to perform synchronous opening and closing movements along the T-shaped grooves 20.

[0020] The two second cylinders 12 are distributed in a mirror image, and the two second cylinders 12 are inclined. The first cylinder 31 is fixedly installed at one end of the conveyor belt 3, and the output end of the first cylinder 31 is fixedly connected to a K-shaped plate 32. The outer surface of the K-shaped plate 32 slides and fits with the outer surface of the conveyor belt 3. The two inclined second cylinders 12 are for the convenience of driving the two trimming grinding heads 13 to grind and trim the rubber ring on both sides under the drive of the second cylinder 12. The function of the first cylinder 31 and the K-shaped plate 32 is to push out the first cylinder 31 by starting the K-shaped plate 32, perform two-point clamping and positioning under the push of the first cylinder 31, and push the rubber ring to the designated position for easy grasping.

The six transmission slots 25 are arc-shaped, and the outer surfaces of the six connecting pins 26 slide in contact with the inner walls of the six transmission slots 25. The annular array distribution is to facilitate the rotation of the rotating shaft 23, and the six engaging links 22 are moved between the corresponding transmission slots 25 to perform synchronous radial movement between the inner walls of the T-slots 20, thereby achieving synchronous opening and closing actions.

[0022] Working principle: When the rubber ring needs to be trimmed continuously, the rubber ring is transported to the K-shaped plate 32 through the top of the conveyor belt 3, and the first cylinder 31 is started. The output end of the first cylinder 31 pushes the K-shaped plate 32 forward along the inner walls of the two ends of the conveyor belt 3, so that the rubber ring is positioned and pushed to a position flush with the relative clamping mechanism 2. Then, the connecting plate 43 is driven to move horizontally through the movement of the electric slide rail 41 and the electric slider 42. The connecting plate 43 drives the top transfer mechanism 5 to extend. The extended transfer mechanism 5 drives the adjustment plate 54 to rotate by starting the second motor 53. The rotating adjustment plate 54 drives the disc 56 to rotate. The rotating disc 56 The transmission shaft 57 at the eccentric position drives the lifting plate 58 to rotate eccentrically. The rotating lifting plate 58 slides vertically up and down between the inner walls of the limiting plate 59 under the restriction of the limiting plate 59. When the lifting plate 58 moves to a certain position, the rubber ring grabbing head 50 at the bottom grabs the rubber ring. After grabbing the rubber ring, the transfer mechanism 5 performs a linear recovery motion through the electric slide rail 41 and the electric slider 42. When the rubber ring is aligned with the center point of the clamping mechanism 2, the eccentric motion of the transfer mechanism 5 again places the rubber ring on the top of the clamping mechanism 2, and the cycle is repeated, so as to achieve a reciprocating transfer motion of the rubber ring continuously transported by the conveyor belt 3.

[0023] When the rubber ring needs to be trimmed, the first motor 29 in the clamping mechanism 2 is started. Under the output of the first motor 29, the rotating shaft 23 is driven to rotate through the worm 28 and the worm wheel 27. The rotating shaft 23 drives the rotating disk 24 sleeved on the outer surface to rotate. The rotating rotating disk 24 drives the six connecting pins 26 to rotate through the transmission groove 25 opened on the outer surface. Due to the arc design of the transmission groove 25, the six connecting pins 26 drive the six engaging connecting rods 22 to perform telescopic movement along the six T-slots 20 with the rotating shaft 23 as the center point, thereby achieving the synchronous clamping movement of the arc plates at one end of the six engaging connecting rods 22, so that the rubber ring is clamped and fixed. The fixed rubber ring is output through the second cylinder 12 on both sides of the U-shaped seat 1, and the two trimming grinding heads 13 are in contact with the rubber ring. Then, the trimming operation of the rubber ring is completed by rotating the rotating seat 14.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
