[0010] By adopting the above technical scheme, the workers can adjust the positions between the slitting knife and the knife groove according to the values on the dial indicator or the micrometer.

[0011] Preferably, the detection end of the measuring rod of the measuring element is flush with the cutting end of the slitting cutter.

[0012] By adopting the above technical scheme, the detection stability of the measuring element is improved.

[0013] Preferably, the measuring element is a pressure sensor.

[0014] By adopting the above technical scheme, the staff adjusts the compression force between the slitting cutter and the cutter groove according to the value of the pressure sensor, reducing the possibility of the slitting cutter being too tight or too loose.

[0016] By adopting the above technical scheme, the driving motor drives the lead screw to rotate, the lead screw drives the connecting block to move along the length direction of the lead screw, and the connecting block drives the second roller to move.

[0017] Preferably, the mounting frame is provided with a guide rail along the width direction, and the connecting block is provided with a guide block located on the guide rail.

[0018] By adopting the above technical scheme, the guide rail and the guide block improve the stability of the connecting block when moving.

[0019] Preferably, the end of the second roller away from the connecting block is provided with a support seat, the mounting frame is provided with a slide rail along the width direction, and the bottom surface of the support seat is provided with a sliding block located on the slide rail.

[0020] By adopting the above technical scheme, the support seat improves the stability of the other end of the second roller, and the slide rail and the sliding block improve the stability of the movement of the second roller.

[0021] In summary, the driving assembly is used to drive the second roller to move to adjust the compression force or the distance between the slitting cutter and the cutter groove, and the measuring element facilitates the staff to adjust the position of the second roller according to the measurement value, effectively avoiding the distance between the second roller and the first roller being too close or too far, thereby causing the slitting cutter and the cutter groove to be too tight or too loose, thereby prolonging the service life of the slitting cutter.

A slitting cutter 4 is fixedly installed on roller one 2, which extends along the circumferential direction of roller one 2 in the present application, which is convenient for cutting materials. A cutter groove 5 corresponding to the slitting cutter 4 is provided on roller two 3, and in the specific implementation process, a cutter cooperating with roller one 2 can also be installed on roller two 3, which is convenient for slitting materials. In order to facilitate the adjustment of the compression force or the distance between the slitting cutter 4 and the cutter groove 5, a driving assembly 6 is fixedly installed on the mounting rack 1, which is used to drive roller two 3 to move towards roller one 2. Also in order to facilitate the staff to understand or adjust the distance between roller two 3 and roller one 2, a measuring element 7 is fixedly installed on the mounting rack 1, which is used to detect the movement data between roller one 2 and roller two 3.

[0026] Referring to Figure 1 , the fixed rack 8 is fixedly installed on the mounting rack 1, and the measuring element 7 is fixed on the fixed rack 8. In the present application, the measuring element 7 is a dial gauge or a micrometer or a pressure sensor. When the measuring element 7 is a dial gauge or a micrometer, the fixed rack 8 fixes the measuring element 7, and the measuring rod of the measuring element 7 is aligned with the central axis of roller two 3, and the central axis of the measuring rod in the length direction of the measuring rod is perpendicular to the rotation axis of roller two 3. The detection end of the measuring rod of the measuring element 7 is flush with the cutting end of the slitting cutter 4. When the driving assembly 6 drives roller two 3 to move towards roller one 2, the slitting cutter 4 penetrates into the cutter groove 5, the measuring rod contacts the outer side wall of roller one 2 for measurement, the measuring rod moves, drives the dial of the measuring element 7 to rotate, and the staff controls the driving assembly 6 to start according to the value, and then drives roller two 3 to move close to or away from roller one 2.
