As shown in fig. 4, the chain 1 is formed by connecting a plurality of chain links 2 end to end, the adjacent chain links 2 are connected by two chain plates 3, the two chain plates 3 are respectively located at two sides of the chain links 2, one chain pin 11 passes through the chain links 2 and the two chain plates 3, and the chain pin 11 is a hinge shaft of the adjacent two chain links 2. The side of the chain 1 close to the sheet 20 is detachably connected with a plurality of mounting plates 4, and the distance between any two adjacent mounting plates 4 on the same chain 1 is the same.

Referring to fig. 5 and 6, the mounting plate 4 is L-shaped and is formed by fixedly connecting a vertical plate 22 and a horizontal plate 23, a blade 7 is fixed on the horizontal plate 23 of each mounting plate 4, the blade 7 faces vertically and faces to the lower surface of the sheet material 20, the blade 7 is fixed on the mounting plate 4 in a manner that the upward surface of the horizontal plate 23 is provided with a T-shaped barrel slot 5, the T-shaped barrel slot 5 is communicated with both ends of the horizontal plate 23 along the length direction of the chain 1, a rectangular sliding plate 6 is arranged in the T-shaped barrel slot 5, the sliding plate 6 can only move along the length direction of the chain 1 under the limit action of the T-shaped barrel slot 5, the blade 7 is fixed on the upper surface of the sliding plate 6, the upper surface of the horizontal plate 23 is further screwed with a first screw 9, the first screw 9 extends into the T-shaped barrel slot 5 to abut against the upper surface of the sliding plate 6, so that the sliding plate 6 is fixed relative to the horizontal plate 23, the sliding plate 6 is moved to a designated position in the T-shaped barrel slot 5, and then the first screw 9 is rotated to press and.

Referring to fig. 5 and 6, two rows of wheel shafts 18 are vertically fixed on the upper surface of the sliding plate 6, rotatable rollers 19 are mounted on the wheel shafts 18, and the two rows of rollers 19 are respectively in rolling contact with two side surfaces of the inner wall of the T-shaped through groove 5. Because the roller 19 is in rolling contact with the inner wall of the T-shaped through groove 5, the friction force between the roller and the T-shaped through groove 5 is small, so that the friction resistance borne by the sliding plate 6 when the sliding plate slides in the T-shaped through groove 5 is reduced, and the position of the sliding plate 6 can be adjusted more quickly and more laborsavingly.

Referring to fig. 4 and 7, the blades 7 are thin, the edge line 8 at the top of each blade 7 is 5cm long, and the distance between the edge lines 8 of two adjacent blades 7 is equal to the length of one product. The connection mode of the chain 1 and the sheet 20 is as follows: the blade 7 of the chain 1 is inserted at the dividing line of two adjacent products on the sheet 20 and the edge line 8 coincides with the dividing line).

As shown in fig. 7, barbs 17 are provided on both sides of the blade 7, and after the blade 7 pierces the sheet 20, the sheet 20 is not easily separated from the blade 7 due to the blocking of the barbs 17.
