[0026] Combine Figures 2-4 Positioning assembly 4 includes positioning roller 41 and connecting shaft rod one 42 installed in the inside of positioning roller 41, one end of connecting shaft rod one 42 is opposite to displacement small block 5, and track side plate 2 includes plate body 21 installed in the side surface of conveying board 1 and track groove 22 opened in the upper surface of plate body 21, the central installation of track groove 22 has the partition strip 23, and two displacement small blocks 5 are distributed at the both sides of partition strip 23, and the circumferential side surface of connecting shaft rod one 42 is installed with extrusion lugs 43, and extrusion lugs 43 are used for extruding paperboard surface, and displacement small block 5 includes swivel ring 51 installed in the side surface of displacement small block 5 and force arm rod 52 set in the circumferential side of swivel ring 51, and the side surface of force arm rod 52 is opposite to top pressure subassembly 3.

[0027] In this embodiment, the side surface of force arm rod 52 is opened in limit groove 53, the center of swivel ring 51 is provided with connecting shaft rod two 54, swivel ring 51 is fixedly connected with connecting shaft rod two 54, and connecting shaft rod two 54 is fixedly connected with connecting shaft rod one 42 through displacement small block 5, top pressure subassembly 3 includes drive turntable 31 installed in the side surface of plate body 21 and traction arm rod 32 set in the outside side surface of drive turntable 31, and traction arm rod 32 is provided with two, and both sides of drive turntable 31 are installed with translation push rod 33, and the outside surface of translation push rod 33 is provided with U-shaped limit rod 34, and U-shaped limit rod 34 is fixedly installed on the outside vertical surface of plate body 21, and the inner dimension of translation push rod 33 and U-shaped limit rod 34 is matched, and both ends of traction arm rod 32 are provided with movable shaft, and one end of traction arm rod 32 is opposite to the side surface of drive turntable 31 through movable shaft, and the other end of traction arm rod 32 is opposite to the side surface of one end of translation push rod 33 through movable shaft, and the positions of two traction arm rods 32 are opposite, and they are parallel to each other, and one end of translation push rod 33 is connected with limit groove 53 through limit small block.

[0028] In this embodiment, the paperboard is delivered to the lower end of the positioning assembly 4 by the conveying plate 1, and the cutting line of the paperboard is aligned between the two sets of positioning assemblies 4. The drive turntable 31 is started, and the two translation push rods 33 are displaced in opposite directions under the push of the traction arm rod 32. The translation push rod 33 always remains in translation by the limiting of the U-shaped limiting rod 34. The force arm rod 52 is subjected to a pressing force, which drives the overall small-amplitude oscillation of the positioning assembly 4. Since the two force arm rods 52 oscillate in opposite directions, the pressing blocks 43 are attached to the surface of the paperboard, and the cutting line is located between the two pressing blocks 43, thereby completing the cutting;
