When the cutting point of the blade is replaced, the whole knife rest mechanism can be realized by rotating the adjusting screw in production without stopping the machine or disassembling the knife rest; the utilization rate of the blade is improved; and compared with the worn blade and the worn blade replacement, the production efficiency is improved to a certain extent, the technical requirements of operators are reduced, and the labor cost is reduced.
Because the fixed clamp cutter block is provided with two positioning holes which are matched with the sizes of the two mounting holes on the blade to position the height of the blade, the height of the blade meets the condition that the cutting point of the blade is superposed with the connecting line center of the two roller shafts and the working center of the two distance pieces, the blade is positioned on the fixed clamp cutter block through two short pins, the blade is quickly mounted, the position correction is not needed, and the positioning is reliable.
Because the positioning hole and the avoidance hole are arranged on the middle line of the blade, the lower part of the blade is also provided with a cutting edge, the upper and lower edges of the blade can be clamped for use, the installation is convenient and fast, and the utilization rate of the blade is improved.
Because the locking screw is a butterfly bolt, the mounting and dismounting are convenient, and the accident that the blade is damaged due to excessive mounting is prevented.
