[0044] The first eccentric rotating member drives the first connecting shaft to reciprocate back and forth, and the first transmission swing arm swings up and down around the first transmission shaft driven by the first connecting shaft. Since the first transmission shaft is fixedly connected to the first transmission swing arm, the first transmission shaft rotates clockwise and counterclockwise around the axis driven by the first transmission swing arm. The cutter swing arm fixedly connected to the first transmission shaft swings up and down with the first transmission shaft, and the cutter pull rod reciprocates and rises and falls driven by the cutter swing arm to realize the opening and closing of the cutter and the cutter base, thereby realizing the cutting function of the cross-cutting component.

The second connecting plate is hinged to the second transmission swing arm, and power is transmitted to the third transmission shaft through the second connecting plate.

[0046] The manner in which the third eccentric rotating member drives the third transmission mechanism is the same as the manner in which the second eccentric rotating member drives the second transmission mechanism, and thus will not be described in detail.

[0047] The first eccentric rotating member and the third eccentric rotating member are sleeved on the driving main shaft, the second eccentric rotating member is arranged at both ends of the driving main shaft, and the lower hot knife beam linked with the third transmission mechanism is arranged on the inner side of the upper hot knife beam. The lower hot knife beam is located on the inner side of the horizontal sealing frame, and the upper hot knife beam is located in the outer sheet metal of the horizontal sealing frame. Such a structural arrangement is more reasonable and the structure is more compact.

[0048] When the size of the bag changes, the position of the cross-cutting assembly on the cross-sealing frame can be changed accordingly through the position adjustment assembly. The ball screw rotates under the drive of the adjustment motor and drives the nut seat to move back and forth along the axial direction of the ball screw. The adjustment connecting rod connected to the nut seat pushes the cutter base to slide on the cross-sealing frame to achieve the overall position adjustment of the cross-cutting assembly.
