It should be noted that, in another embodiment, referring to fig. 5 to 8 together, the first adjusting roller 30 includes a roller shaft 100, a first bearing 200, a second bearing 300, a roller 400 and an adjusting assembly 500. 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 slitting machine, one end of the roller 100, which is sleeved with the first bearing 200, is fixed on the base 10. Thus, when the tension on both sides of the material is not uniform, the second end 420 can be controlled to swing relative to the roller shaft 100 by rotating the adjusting screw 540 to change the position of the material at the second end 420, thereby adjusting the tension on both sides of the 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 types of the first bearing 200 and the second bearing 300, the adjustment accuracy and the service life of the first adjustment roller 30 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. 6 and 7, the lead screw nut 550 has a spherical structure. The first dancer 30 also 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. When the lead screw 540 rotates, the lead screw 540 swings together with the second end 420 with respect to the roller shaft 100. At this time, the lead screw nut 550 can rotate with respect to the roller shaft 100, preventing the insert 560 from restricting the swing of the second end 420.

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. 7, 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.

Thus, the end surface of one end of the second segment 542 abuts against the first screw base 520, the end surface of the other end abuts against the second screw base 530, and the first screw base 520 and the second screw base 530 can move along the axis of the adjustment screw 540 together with the adjustment screw 540, so that the second end 420 swings.

Specifically, the second screw base 530 includes a screw base 531 and a shaft plug 532, the screw base 531 is connected to the roller cover 510, and a first fitting hole 5311 is formed in the screw base 531. The shaft plug 532 is located in the first fitting hole 5311 and is screw-coupled with the lead screw base 531. The shaft plug 532 is provided with a second assembly hole 5321, the inner diameter of the second assembly hole 5321 is smaller than the outer diameter of the second section 542, and the third section 543 is located in the second assembly hole 5321. During installation, the first screw seat 520 and the screw base 531 may be connected to the roller cover 510, and then the adjusting screw 540 sequentially passes through the first assembling hole 5311, the screw nut 550 and the first screw seat 520 until the end surface of the second section 542 abuts against the first screw seat 520. Finally, the shaft plug 532 is screwed to the screw base 531, and the end surface of the shaft plug 532 abuts against the end surface of the second segment 542, thereby restricting the movement of the adjustment screw 540 along the axis thereof with respect to the first screw base 520 and the second screw base 530.

Further, in the present embodiment, referring mainly to fig. 5 and 7, the adjusting assembly 500 further includes a mounting cover 570, the mounting cover 570 is connected to the first screw base 520 and the second screw base 530, and the first screw base 520, the second screw base 530 and the screw nut 550 are all located in the mounting cover 570. The mounting cover 570 is provided with a visible area 571 and a calibration area 572, and the visible area 571 and the calibration area 572 are used for observing the swing distance of the second end 420. Specifically, the visible area 571 is a transparent area or a hollow area. The adjustment assembly 500 further includes a position indicating plate 580 fixedly connected to the roller shaft 100, the position indicating plate 580 being provided with a position indicating line, the position indicating line being located in the visible region 571. The scale area 572 is provided with a scale, and when the adjusting screw 540 is rotated, the mounting cover 570 is moved so that the scale indicated by the position indicating line is changed, so that the user can know the swing distance of the second end 420.

Further, in the present embodiment, as shown in fig. 5 and fig. 6, the adjusting assembly 500 further includes a knob 590, the knob 590 is sleeved on the adjusting screw 540, and the adjusting screw 540 can rotate along with the knob 590, so as to facilitate the operation of the user.

It is worth mentioning that the accuracy of the scale in the scale area 572 is less than the accuracy of the scale on the knob 590. Thus, the user can adjust the second end 420 to a desired position based on the value in the scale field 572, and then adjust the second end precisely based on the scale on the knob 590.

Of course, it is understood that the second dancer roll 40 may also be constructed in the same manner as the first dancer roll 30 to adjust the tension on both sides of the material in contact with the second dancer roll 40.
