The cam transmission device 220 realizes the reciprocating motion of the clamping device 210 through the transmission cooperation of the cam mechanism 223 and the link mechanism 2240, a certain included angle is formed between the first link 2242 and the second link 2243, so that the two links swing in the vertical direction and the horizontal direction respectively, the first link 2242 and the second link 2243 are fixedly arranged on the rotating shaft 2241, the two links keep synchronous motion, when the first link 2242 swings in the horizontal direction, namely, the clamping device 210 moves in the forward direction, the second link 2243 swings downwards, the second link 2243 swings upwards, namely, the clamping device 210 resets, and the stability of the cam transmission device 220 can be improved through the cooperation of the two links; the included angle between the first link 2242 and the second link 2243 is set to be 80 ° to 100 °, the cam mechanism 223 is arranged in sufficient space between the two links, and the included angle between the two links is too small, so that the length of the two links needs to be increased to ensure the displacement distance of the clamping device 210, and the included angle between the two links is too large, so that the size of the cam mechanism 223 is too large, which is not beneficial to installation.
Further, the reciprocating motion of the driving seat 222 is controlled by the first link 2242, so that the reciprocating displacement of the driving seat 222 is directly related to the length of the first link 2242, in order to ensure the displacement distance of the driving seat 222 without enlarging the size of the cam gear 220, the length of the second link 2243 is set smaller than the length of the first link 2242, the swinging angle of the second link 2243 is consistent with the length of the first link 2242, the length of the second link 2243 is shortened, the coverage range of the second link 2243 when swinging can be reduced, a larger space is not required to be reserved in the height direction of the second link 2243, and in a practical product, the length of the first link 2242 is smaller than half of the length of the first link 2242.

The swing of the first link 2242 is controlled by the first cam 2231, the swing of the second link 2243 is controlled by the second cam 2232, the edge of the cam contacts with the link, the edge position of the cam is far from the rotation center of the cam, and the swing angle of the two links and the displacement distance of the clamping device 210 can be ensured; if the first link 2242 is disposed on the left side of the first cam 2231, when the first cam 2231 pushes the first link 2242 to move rightward, the clamping device 210 moves rightward, and meanwhile, the second link 2243 is driven by the first link 2242 to swing downward, the first link 2242 cannot be controlled to reset by continuing to rotate, the second link 2243 is pushed by the second cam 2232 to swing upward, so that the first link 2242 is driven to move leftward to reset and simultaneously move leftward with the clamping device 210, the two cams are only responsible for swinging along one direction of the connecting rods contacting with the first link 2242, and the two connecting rods are connected with each other to realize linkage, and the cams are only abutted against the connecting rods, so that abrasion between the two connecting rods is small in the transmission process, and the loss of equipment is reduced.
Referring to fig. 4 and 5, in another embodiment of the present invention, a transmission connection structure between the first link 2242 and the driving seat 222 is specifically described, based on the above embodiment:
the driving seat 222 is connected with the first link 2242 through a third link 2244, one end of the third link 2244 is connected with the driving seat 222, and the other end is hinged with the first link 2242, so that when the first link 2242 swings, the movement track of the end part of the first link 2242 is arc-shaped, instead of being horizontal, and the reciprocating movement of the driving seat 222 can be controlled through the third link 2244 by hinging the third link 2244.
If so, the motion track of the end of the third link 2244 connected to the first link 2242 is also arc-shaped, which results in a shorter displacement distance of the driving seat 222 and is unfavorable for conveying products, for this purpose, a rod fixing seat 2245 is provided on the first link 2242, at least two guide links 2246 are fixedly connected to the rod fixing seat 2245, at least two guide links 2246 extend in the length direction of the first link 2242, at least two guide links 2246 are slidably provided with a link slider 2247, one end of the third link 2244 is hinged with the link slider 2247, the other end is fixedly connected with the driving seat 222, at least two guide links 2246 can limit the rotation of the link slider 2247, so that the link slider 2247 slides only along the guide link 2246, the guide link 2246 can swing synchronously with the first link 2242 under the action of the rod fixing seat 2245, so that when the first link 2242 swings, the third link 2244 reciprocates in the horizontal direction, the link 2247 slides along the guide link 2246, and maintains the horizontal direction of the third link 2244, thereby maintaining the horizontal displacement of the clamping device 210.
