[0024] A marking mechanism 8 is provided in the middle of the pressure roller 1. Figure 2 As shown, the marking mechanism 8 includes a semicircular first marking ring 81 and a second marking ring 82, the first marking ring 81 and the second marking ring 82 are located in the middle of the pressure roller 1 and abut against the two ends of the pressure roller 1, and a slot 83 is provided on the first marking ring 81 and the second marking ring 82, the depth of the slot 83 is not more than 2 mm, and the width of the slot 83 is equal to the width of the finished product, and the slot 83 with a small depth is used to prevent the raw material from being stuck in the slot 83, the slots 83 on the two marking mechanisms 8 are staggered, and one end of the slot 83 on one marking mechanism 8 and the other end of the slot 83 on the other marking mechanism 8 are located on the same vertical line, and the slot 83 forms a step shape after the raw material is squeezed by the pressure roller 1, thereby marking the raw material, so that there is no need for subsequent measurement work, and cutting can be directly performed along the mark, which has high accuracy and improves work efficiency.
[0025] like Figure 2As shown, a slot 84 is provided at the end of the first marking ring 81, and an insert block 85 connected to the slot 84 is fixed at the end of the second marking ring 82. A fixing bolt 86 is inserted on the pressure roller 1, and the fixing bolt 86 passes through the pressure roller 1 and the insert block 85, and the fixing bolt 86 is threadedly connected to the inner wall of the slot 84. The slot 84, the insert block 85 and the fixing bolt 86 can be conveniently disassembled between the first marking ring 81 and the second marking ring 82, and between the marking mechanism 8 and the pressure roller 1, so that the marking mechanism 8 with different slot 83 widths can be freely replaced, further increasing the scope of application.
