[0027] In order to improve the stability of the bottom knife sleeve 17 and facilitate use, when in use, the shaft sleeve 2, the telescopic sleeve 8 and the bottom knife sleeve 17 are a group. When the bottom knife sleeve 17 is installed on the lower rotating shaft 1, the staff first inserts the right end sleeve 15 and the right top tightening sleeve 16 from one side of the lower rotating shaft 1, so that the right end sleeve 15 and the right top tightening sleeve 16 are strung to the rightmost side of the lower rotating shaft 1, and then aligns the first limiting slider 10 on the inner surface of the telescopic sleeve 8 with the limiting slide groove 9 on the outer surface of the lower rotating shaft 1, and then puts the shaft sleeve 2, the telescopic sleeve 8 and the bottom knife sleeve 17 on the outer surface of the lower rotating shaft 1. According to the requirements of the slitting quantity, different numbers of bottom knife sleeves 17 are installed so that each group of telescopic sleeves 8, the first limiting slider 10 and the first limiting slider 9 on the outer surface of the lower rotating shaft 1 are The circular hole 3 and the bottom knife sleeve 17 are first abutted, and finally the left end sleeve 11 and the left tightening sleeve 13 are passed through the left side of the lower rotating shaft 1. After the installation is completed, the spacing between the bottom knife sleeves 17 is adjusted according to the slitting parameters. During the adjustment process, the staff uses an iron rod to insert into the first circular hole 3 on the surface of the sleeve 2, and then rotates the sleeve 2. As the sleeve 2 rotates, the two symmetrically distributed telescopic sleeves 8 threaded on the inner surfaces of both sides of the sleeve 2 move inward or outward synchronously. During the movement, the first limit slider 10 on the inner surface of the telescopic sleeve 8 slides in the limit slide groove 9 on the outer surface of the lower rotating shaft 1, which plays a role of limiting. By controlling the positions of the two telescopic sleeves 8, the relative After adjusting the spacing between the two adjacent bottom knife sleeves 17, the staff uses a hexagonal wrench to insert it into the hexagonal slot 6, tightens the threaded rod 5 into the threaded hole 4, and makes the threaded rod 5 move inward in the threaded hole 4, thereby driving the inner side of the arc-shaped top block 7 to press against the outer surface of the lower rotating shaft 1, thereby fixing the shaft sleeve 2. After completion, the baffle is installed on the left end of the lower rotating shaft 1. Since the left port sleeve 11 and the right port sleeve 15 are located at both ends, the staff uses an iron rod to insert it into the second circular hole 14 on the surface of the left tightening sleeve 13, so that the second circular hole 14 is rotated to the right on the surface of the left port sleeve 11, thereby making the left tightening sleeve 13 on the left port sleeve 1 1 moves outward, and the left end sleeve 11 and the left top tightening sleeve 13 are gradually separated. The left side of the left end sleeve 11 abuts on the baffle on the left side of the slitting machine, and the right side of the left top tightening sleeve 13 abuts on the end face of the telescopic sleeve 8 located on the far left.
