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. When it presses to the top of the box, the blade retracting mechanism is controlled to extend the blade, and the tip of the blade is stuck in the tape. Under the push of the box pushing mechanism, the center seam cutting is completed. The roller group, the center seam pressing plates on both sides and the rollers of the first station conveyor are set Under the comprehensive guiding effect of the cylinder, the cutting process is more stable, the problem of poor slitting quality caused by shaking is avoided, the slitting is more accurate, the parallelogram mechanism is linked, and while pressing is achieved, the blade connected in the middle also achieves accurate middle positioning in the vertical direction, and the structure is greatly simplified. In order to strengthen the swing stability of the parallelogram mechanism 110, a second parallelogram mechanism 131 is connected in parallel to the outside of the parallelogram mechanism, and the two top hinge points of the second parallelogram mechanism 131 are hinged to the two side connecting rods of the parallelogram mechanism 110 through the hinged long axis 132.

Under the auxiliary reinforcement of the second parallelogram mechanism 131, the swing is more stable.The pressing box is more stable, and the height of the second parallelogram mechanism 131 is lower than that of the blade telescopic mechanism to avoid interference during the telescopic process of the blade telescopic mechanism. The lower ends of the connecting rods on both sides of the parallelogram mechanism are hinged on the gate-shaped main bracket. 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.

[0079] The above-mentioned blade telescopic mechanism includes a guide mounting plate 116, a blade guide shaft 117 and a telescopic cylinder 118. A horizontal strip hole is arranged at the guide mounting plate 116 opposite to the knife groove 127 to increase the extension adjustment range of the blade. The blade holder 109 is fixedly connected to the guide mounting plate 116. Two blade guide shafts 117 are used, and the same end is fixedly connected to the two sides of the guide mounting plate 116.

The cylinder rod of the telescopic cylinder 118 is fixedly connected to the connecting ear in the middle of the top side of the guide mounting plate 116. The cylinder seat of the telescopic cylinder 118 is fixedly connected to the side of the middle connecting rod 111 through an L-shaped cylinder frame 133. The telescopic cylinder pushes the guide mounting plate to move, thereby realizing the position movement of the blade holder, and realizing the middle seam blade being stuck into the middle seam tape on the side of the box body.

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 position of the two limit baffles 138 is located within the tip of the slit blade after it is retracted, so as to preliminarily position the box to avoid hitting the blade. 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. An integrated connecting plate is arranged at the bottom of each limit baffle 138 to facilitate installation and improve support rigidity. The first parking device assembly 104 includes an L-shaped baffle plate 139 and a limit telescopic cylinder 140.

The crossbeam 143 is fixedly connected to the first conveyor frame 135. The cylinder rod of the limit telescopic cylinder 140 is fixedly connected to the middle of the baffle plate 139. The two stopper guide rods 141 are arranged on both sides. The cylinder seat 40 is fixedly connected to the crossbeam 143.
