[0021] Further, a pressing block 601 is provided at the upper end of the inner end of the frame 6, and a cushion block 701 is provided in the middle of the second connecting shaft 7.

[0022] Further, a pressing piece 602 is movably arranged on the lower end surface of the pressing block 601. A pressure-sensitive resistor 603 is arranged between the pressing piece 602 and the lower end surface of the pressing block 601. The pressure-sensitive resistor 603 is electrically connected to the controller 5. Springs 604 are arranged in an array between the pressing piece 602 and the pressing block 601.

[0023] Further, it further includes a cylinder 101 connecting the front end of the frame beam 1 and the lower end of the support arm 2. Both ends of the cylinder 101 are hinged to the front end of the frame beam and the lower end of the support arm 2.

[0024] Embodiment 1:

[0025] The rear end of the support arm 2 is hinged to the middle of the frame beam 1. A carrier plate is continuously arranged at the front part of the support arm 2. The carrier plate bends downward and the lower part extends towards both ends. The first connecting shaft 201 is mirror-arranged at the lower part between the carrier plates. The second connecting shaft 7 is mirror-arranged at the upper part of the carrier plates. The rear part of the swing body 3 is rotationally connected to the first connecting shaft 201. A pressing wheel 4 is rotatably arranged at the lower end of the front part of the swing body 3. A frame 6 is arranged at the upper end of the swing body 3. The two side edges of the frame 6 are curved. When the swing body 3 rotates upward, the frame 6 will move upward accordingly, and the curved side frame will not collide with the second connecting shaft 7. A pressing block 601 is arranged on the inner end surface of the upper part of the frame 6. The second connecting shaft 7 passes through the center of the frame 6. A cushion block 701 is arranged in the middle of the second connecting shaft 7. A pressing piece 602 is arranged at the lower end of the pressing block 601.

Springs 604 are connected to the four corners of the pressing block 601 and the pressing piece 602. The cardboard is transported in a stacked manner during transportation. Therefore, when the front pressing wheel 4 is raised according to the slope of the cardboard, the pressing block 601 in the frame 6 is separated from the cushion block 701 of the second connecting shaft 7. When the pressing wheel 4 rolls over the edge, the swing body 3 will be raised and the pressing block 601 is separated from the cushion block 701. When the pressing wheel 4 presses over the high place and then falls, the swing body 3 and the frame 6 fall. At this time, the pressing block 601 and the cushion block 701 come into contact again. When contacting, the pressing piece 602 receives the pressure and transmits the pressure to the pressure-sensitive resistor 603. The pressure-sensitive resistor 603 transmits the signal to the controller 5. The controller 5 is provided with a counting unit. The pressure-sensitive resistor 603 is counted once by the controller 5 when it receives a pressure. And when the front pressure-sensitive resistor 603 gets a count, the rear part also gets a count. When the counts obtained from the front and rear are the same, the counting is accurate.
