[0035] As an implementation manner, the second driving member 12 includes a lower knife cam 120, a lower chuck cam 121, and a lower follower connection assembly 122. The lower knife cam 120 is disposed on a first side of the lower chuck cam 121 along the length direction of the first rotating shaft 10. The upper chuck cam 111 is disposed at an interval on a second side of the lower chuck cam 121 along the length direction of the first rotating shaft 10, and the upper chuck cam 111 and the lower chuck cam 121 are disposed adjacent to each other at an interval. The first end of the lower follower connection assembly 122 is disposed on the lower knife cam 120, and the second end of the lower follower connection assembly 122 is disposed on the lower chuck cam 121.

[0036] Specifically, the lower follower connection assembly 122 includes a lower knife follower block, a follower, and a follower fixing block. The follower fixing block is fixedly installed at the bottom of the lower knife follower block. The follower is disposed on the lower knife follower block and is fixedly connected to the follower fixing block.

[0037] Specifically, a second groove is formed on the lower knife cam 120. The second end of the first actuating assembly 13 is disposed in the first groove. The second groove is configured to drive the second end of the first actuating mechanism to move along the direction in which the second groove is formed, so as to drive the first actuating mechanism.

[0039] As an implementation manner, the first actuating assembly 13 includes a first swing rod 130, a second swing rod 131, and a fixing plate 132. The first swing rod 130 and the second swing rod 131 are disposed at an interval. The first end of the first swing rod 130 is disposed on the upper knife cam 110. The first end of the second swing rod 131 is disposed on the lower knife cam 120. Fixing plates 132 are disposed at the second ends of the first swing rod 130 and the second swing rod 131.

[0040] Specifically, followers are disposed at both ends of the first swing rod 130 and the second swing rod 131.

[0041] It can be seen that both ends of the first swing rod 130 and the second swing rod 131 are adjustable, the structure is simple, and the operation is convenient.

[0042] As an implementation manner, the third driving member 21 includes a pin cam, and the pin cam is sleeved on the second rotating shaft 20.

[0043] It can be seen that the pin cam rotates through the second rotating shaft 20 for driving.

[0046] Specifically, a third groove is formed in the pin-inserting cam. The bottom of the third swing rod 221 is arranged in the third groove. The third groove is configured to drive the bottom end of the third swing rod 221 to move along the direction in which the third groove is formed, so as to drive the second actuating mechanism.

[0047] It can be seen that by movably mounting the third swing rod 221 on the rotating seat 220, the third swing rod 221 can move up and down as the pin-inserting cam rotates, and the pin-inserting work is completed through cooperation.

[0048] The specific working principle of the above cam driving mechanism is as follows:

[0049] The first rotating shaft 10 rotates to drive the upper knife cam 110, the upper chuck cam 111, the lower knife cam 120, and the lower chuck cam 121 to rotate synchronously. The upper knife cam 110 and the lower knife cam 120 rotate to make the first actuating assembly 13 work. The second rotating shaft 20 rotates to drive the pin-inserting cam to rotate, and the pin-inserting cam drives the third swing rod 221 to move up and down.
