The first bearing 200 and the second bearing 300 are both sleeved on the roller shaft 100, and the first bearing 200 and the second bearing 300 are disposed at intervals. The roller 400 includes a first end 410 and a second end 420 disposed opposite to each other, wherein the first end 410 is sleeved on the first bearing 200, and the second end 420 is sleeved on the second bearing 300. The adjusting assembly 500 includes a roller cover 510, a first screw seat 520, a second screw seat 530, an adjusting screw 540 and a screw nut 550, wherein a mounting hole 511 is formed in the roller cover 510, the roller shaft 100 is inserted into the mounting hole 511, and a gap is formed between the roller shaft 100 and the roller cover 510 to provide a space for the roller cover 510 to drive the second end 420 to swing. The second bearing 300 is sleeved on the roller cover 510, and the first screw base 520 and the second screw base 530 are connected with the roller cover 510. One end of the adjusting screw 540 is rotatably connected to the first screw base 520, the other end is rotatably connected to the second screw base 530, and the screw nut 550 is fitted over the adjusting screw 540 and connected to the roller shaft 100.
When the adjusting screw 540 rotates, the adjusting screw 540, the first screw base 520 and the second screw base 530 all move along the axial direction of the adjusting screw 540 due to the connection of the screw nut 550 with the roller shaft 100. Moreover, since the first screw base 520 and the second screw base 530 are both connected to the roller cover 510, the second bearing 300 is sleeved on the roller cover 510, and the second end 420 of the roller 400 is sleeved on the second bearing 300. When the first screw base 520 and the second screw base 530 move, the roller cover 510 drives the second bearing 300 and the second end 420 to move along the axial direction of the adjusting screw 540. Meanwhile, since the first end 410 of the roll drum 400 is coupled to the roll shaft 100 through the first bearing 200, the second end 420 is swung with respect to the roll shaft 100. In the splitting machine, one end of the roller 100, which is sleeved with the first bearing 200, is fixed on a frame of the splitting machine. Thus, when the tension on both sides of the band-shaped material is not uniform, the second end 420 can be controlled to swing with respect to the roller shaft 100 by rotating the adjusting screw 540 to change the position of the band-shaped material at the second end 420, thereby adjusting the tension on both sides of the band-shaped material. It will be appreciated that the direction in which the second end 420 oscillates can be varied by controlling the direction in which the adjustment screw 540 rotates.
In the present embodiment, the first bearing 200 is a self-aligning ball bearing, and the second bearing 300 is a deep groove ball bearing. When the roll 400 is coaxial with the roll shaft 100, the inner and outer rings of the first and second bearings 200 and 300 are coaxial. When the second end 420 swings, the outer ring of the first bearing 200 swings with respect to the inner ring, and the axis of the outer ring of the first bearing 200 always intersects with the axis of the inner ring. By selecting the type of the first bearing 200 and the second bearing 300, the adjustment accuracy and the service life of the roll can be improved. Of course, in other embodiments, other types of bearings may be used for the first bearing 200 and the second bearing 300.
Further, in the present embodiment, as shown in fig. 2 and 3, the lead screw nut 550 has a spherical structure. The roller further includes an insert 560, and the insert 560 is coupled to the roller shaft 100. The lead screw nut 550 is embedded in the insert 560 to be movably coupled with the insert 560.

Specifically, the insert 560 includes an insert base 561 and an insert cover 562, the insert base 561 is fixedly connected to the roller shaft 100, the insert cover 562 is threadedly connected to the roller shaft 100, and the lead screw nut 550 is inserted into the insert base 561 and the insert cover 562. During installation, the mounting base 561 may be connected to the roller 100, the lead screw nut 550 may be mounted in the mounting base 561, and the mounting cap 562 may be screwed to the roller 100 to limit the movement of the lead screw nut 550 relative to the roller 100. Of course, in other embodiments, the insert cover 562 and the insert roller 100 may be connected in other detachable manners such as snap-fit connection, and the insert cover 562 may also be detachably connected with the insert base 561. Also, the lead screw nut 550 may be embedded only in the inlay base 561 or the inlay cover 562.
It should be noted that, in the embodiment, referring mainly to fig. 3, in order to prevent the lead screw nut 550 and the adjusting screw 540 from rotating together around the axis of the adjusting screw 540, the lead screw nut 550 has a incomplete spherical structure, that is, the surface of the lead screw nut 550 has a plane, and the plane is perpendicular to the axis of the roller shaft 100 when the lead screw nut 550 is inserted into the insert 560. In addition, a boss 563 is disposed on the insert 560 at a position corresponding to the plane. Thus, the flats and bosses 563 limit the rotation of the lead screw nut 550 relative to the insert 560 about the axis of the adjustment screw 540 without affecting the swinging motion of the lead screw nut 550 and adjustment screw 540 along the second end 420. Of course, in other embodiments, the feed screw nut 550 may be of a cylindrical configuration. At this time, the lead screw nut 550 is coaxially disposed with the roller shaft 100, and a gap for the lead screw nut 550 to swing is provided between the outer surface of the lead screw nut 550 and the roller shaft 100 to prevent the roller shaft 100 from restricting the lead screw nut 550 from swinging, thereby restricting the adjusting lead screw 540 and the second end 420 from swinging.
