[0063] The above scheme is adopted: in order to move the cutting knife 401 to the right, the main pulley 603 is rotated to drive the forward and reverse threaded rod 701 to rotate, so that the transmission block 702 moves to the right along the outer surface of the forward and reverse threaded rod 701, and the transmission block 702 can indirectly drive the cutting knife 401.

[0064] refer to Figure 2 As shown, two pressure relief components 8 are provided, and the two pressure relief components 8 include:

[0065] Telescopic column 801: The left end surface of the telescopic column 801 is fixedly connected to the right end surface of the transmission block 702, and the right end surface of the telescopic column 801 is fixedly connected to the left end surface of the cutting knife 401;

[0067] Adopting the above scheme: when the transmission block 702 moves to the right, the transmission block 702 pushes the pressure relief assembly 8 to move together, and the pressure relief assembly 8 drives the cutting knife 401 to move to the right. The pressure relief assembly 8 mainly plays the role of relieving pressure when cutting the packaging film 3 with higher elasticity.

Since the outer surface of the main pulley 603 is connected to the auxiliary pulley 602 through the belt rotation, the main pulley 603 can make the auxiliary pulley 602 rotate in the same direction, and the auxiliary pulley 602 can drive the driving rod 601 to rotate together. The rotation of the driving rod 601 can drive the gear 503 to rotate, and the rotation of the gear 503 meshes with the gear 503. The toothed plate 501 moves upward along the outer surface of the support rod 502. During the upward movement, the packaging film 3 rotates and passes through the stroke groove 10, so that the film contacts the left end surface of the fixed plate 402. At the same time, the main pulley 603 rotates, which can drive the forward and reverse threaded rods 701 to rotate, so that the transmission block 702 moves to the right along the outer surface of the forward and reverse threaded rods 701. The transmission block 702 pushes the pressure relief assembly 8 to move together, and the pressure relief assembly 8 drives the cutting knife 401 to move to the right until the cutting knife 401 passes through the limiting groove 403 on the fixed plate 402, and the packaging film 3 can be separated.
