The side connecting rod of the parallelogram mechanism 110 is hinged to one end of the driving cylinder 115, and the other end of the driving cylinder 115 is hinged to the middle frame assembly 106. The working principle is: the parallelogram mechanism swings by extending the driving cylinder, and then drives the roller group to press down.

The two lower ends of the gate-shaped main bracket are passed through the crossbeam of the middle frame assembly 106 through two screws and each screw is locked up and down with two nuts to achieve height adjustment. The connecting rods on both sides of the second parallelogram mechanism 131 are hinged on the auxiliary mounting plate, and the auxiliary mounting plate is fixedly connected to one side of the gate-shaped main bracket.

[0081] The above-mentioned blade telescopic mechanism includes a guide mounting plate 116, a blade guide shaft 117 and a telescopic cylinder 118.

The push plate 120 is vertically suspended and hinged on a connecting ear 124 arranged at the bottom of the slide plate assembly 122. A vertical baffle 125 is arranged on the front side of the connecting ear 124. The rear end surface of the vertical baffle 125 is arranged with an elastic protective layer 126 that abuts against the top plate at the rear side of the push plate 120. The vertical baffle 125 rotates freely around the hinge axis arranged thereon without interfering with the vertical baffle. The protective layer 126 can reduce shock and noise. The rodless cylinder assembly 121 is installed on the top of the middle frame assembly 106 through the fixed hangers 123 at both ends. When the box needs to be pushed into the first workstation conveyor, the push plate automatically rotates inward during the pushing process. When the box moves to the baffle position of the first parking device assembly, the push plate automatically falls off, and the center seam cutting action on both sides presses the box and the blade extends into the center seam tape. The rodless cylinder is controlled to make the push plate contact the box and push it backwards. Under the pressure of the center seam blade and the roller group, the center seam is cut smoothly, and after the center seam cutting is completed, the box is pushed into the next workstation.

The two limit baffles 138 are connected to the side of the first conveyor frame 135 through two L-shaped support plates. The bolt through holes at the L-shaped support plate connecting the two limit baffles 138 are strip holes, which are convenient for position adjustment. The two ends of the two limit baffles 138 are symmetrically shaped like figures of eight, which play a guiding role.
