[0042] The slitting tool installation shaft 10 of the utility model comprises a first fixed section 11, a second fixed section 12 and a knife mounting section 13 located between the first fixed section 11 and the second fixed section 12. One end of the first fixed section 11 close to the knife mounting section 13 and one end of the second fixed section 12 close to the knife mounting section 13 are detachably connected to two ends of the knife mounting section 13 respectively, and the knife mounting section 13 is used for detachably mounting a lower cutter 20. When the lower cutter 20 actually needs to be replaced, it is only necessary to remove the knife mounting section 13 from the first fixed section 11 and the second fixed section 12 to replace the lower cutter 20. Compared with the prior art, there is no need to perform disassembly and installation operations of the slitting tool installation shaft 10 on two wall panels 30, the operation is relatively convenient, the replacement of the lower cutter 20 is convenient, and the work efficiency is improved.

[0043] Two mounting portions 112 are respectively formed at one end of the first fixed section 11 away from the knife-mounting section 13 and one end of the second fixed section 12 away from the knife-mounting section 13. The end of the mounting portion 112 of the first fixed section 11 (the end is the end of the mounting portion 112 away from the first fixed section 11) is used to be rotatably mounted in the mounting hole on the inner side of the corresponding wall panel 30. The end of the mounting portion 112 of the second fixed section 12 (the end is the end of the mounting portion 112 away from the second fixed section 12) is rotatably arranged on the adjustment component 14, and the adjustment component 14 is used to be detachably mounted on the inner side of the corresponding wall panel 30. In actual application, a rotating bearing can be arranged in the mounting hole, and the rotating bearing is sleeved on the outer periphery of the end of the mounting portion 112 of the first fixed section 11 to provide rotation support for the first fixed section 11.

[0044] Combination Figure 5As shown, the adjustment component 14 includes a rectangular mounting plate 141, and the mounting plate 141 is provided with a fixed section mounting hole and a waist hole 1411 (the waist hole 1411 is a hole with semicircular ends and a rectangular middle) that penetrates both sides of the mounting plate 141. The fixed section mounting hole is located in the middle of the mounting plate 141, and the end of the mounting portion 112 of the second fixed section 12 is rotatably arranged in the fixed section mounting hole. The length direction of the waist hole 1411 is the same as the height direction of the mounting plate 141, and the mounting plate 141 is used to be detachably mounted on the inner side of the corresponding wall panel 30 through the waist hole 1411. In actual application, the waist hole 1411 corresponds to the circular hole on the inner side of the corresponding wall panel 30. By installing a second fastener such as a screw in the waist hole 1411 and the corresponding circular hole, the mounting plate 141 can be installed on the inner side of the corresponding wall panel 30.

It can be understood that the number of waist holes 1411 can be set according to actual conditions.

[0045] In actual application, by installing the second fastener at different positions in the waist hole 1411, the height position of the end of the second fixed section 12 away from the tool mounting section 13 can be adjusted, thereby adjusting the horizontality of the slitting tool mounting shaft 10. For example, assuming that in the initial state, the second fastener is installed in the bottom end of the waist hole 1411 and the corresponding circular hole on the inner side of the wall panel 30. If at this time the end of the second fixed section 12 away from the knife mounting section 13 is higher than the end of the first fixed section 11 away from the knife mounting section 13, that is, the slitting tool mounting shaft 10 is tilted upward as a whole, the second fastener is first removed from the circular hole on the inner side of the wall panel 30 corresponding to the bottom end of the waist hole 1411, and then the mounting plate 141 is moved downward, thereby driving the end of the second fixed section 12 away from the knife mounting section 13 to move downward until the height of the end of the second fixed section 12 away from the knife mounting section 13 is the same as the height of the end of the first fixed section 11 away from the knife mounting section 13, and then the second fastener is installed at the top end of the waist hole 1411 and the corresponding circular hole on the inner side of the wall panel 30. In this way, the position of the end of the second fixed section 12 away from the knife mounting section 13 in the height direction can be adjusted, thereby realizing the horizontality of the slitting tool mounting shaft 10 and ensuring the horizontality of the slitting tool mounting shaft 10.

[0046] A bearing 1412 is disposed in the mounting hole of the fixing section. The bearing 1412 is sleeved on the outer periphery of the end of the mounting portion 112 of the second fixing section 12 . The disposed bearing 1412 provides rotation support for the second fixing section 12 .

The provided limiting plate 1413 limits the bearing 1412. When the mounting plate 141 is installed on the inner side of the corresponding wall panel 30, the wall panel 30 can also limit the bearing 1412.

[0048] In other embodiments, the ends of the mounting portion 112 of the first fixed section 11 and the ends of the mounting portion 112 of the second fixed section 12 can be rotatably arranged on an adjustment component 14, respectively, and the ends of the mounting portion 112 of the first fixed section 11 and the ends of the mounting portion 112 of the second fixed section 12 can be rotatably arranged in the corresponding mounting holes of the adjustment components 14, respectively, and the mounting plates 141 of the two adjustment components 14 are used to be detachably mounted on the inner sides of the two wall panels 30 through their respective waist holes 1411. The bearings 1412 of the two adjustment components 14 are respectively sleeved on the outer periphery of the ends of the mounting portion 112 of the first fixed section 11 and the outer periphery of the ends of the mounting portion 112 of the second fixed section 12. By setting the two adjustment components 14, the position of the end of the first fixed section 11 away from the knife installation section 13 in the height direction can be adjusted, and the position of the end of the second fixed section 12 away from the knife installation section 13 in the height direction can be adjusted, so that the horizontality of the slitting tool installation shaft 10 can be adjusted.
