[0031] Example 1

[0032] A snap-on spacer sleeve includes a left half spacer sleeve 61 and a right half spacer sleeve 62. The left half spacer sleeve 61 and the right half spacer sleeve 62 are both arc-shaped, and the arc lengths of the cross-sections of the left half spacer sleeve 61 and the right half spacer sleeve 62 are equal, so that the left half spacer sleeve 61 and the right half spacer sleeve 62 are symmetrically installed on both sides of the rotating shaft 3.

[0033] Both sides of the front half of the left half spacer sleeve 61 are provided with front latches 611 extending to the right side, and the rear side wall of the front latches 611 is provided with a first latch 612 and a second latch groove 614, and the first latch 612 is located on the side close to the right half spacer sleeve 62, and the second latch groove 614 is located on the side away from the right half spacer sleeve 62.

[0034] Both sides of the rear half of the right half spacer sleeve 62 are provided with rear latches 621 extending to the left, and the front side wall of the rear latches 621 is provided with a second latch 622 and a first latch groove 624, and the second latch 622 is located on the side close to the left half spacer sleeve 61, and the first latch groove 624 is located on the side away from the left half spacer sleeve 61.

[0035] The front protrusion 611 and the rear protrusion 621 are adapted to form the left half spacer 61 and the right half spacer 62 to form a complete cylindrical buckle spacer 6. At this time, the first buckle 612 is inserted into the first slot 624, and the second buckle 622 is inserted into the second slot 614.

[0036] After installing the snap-on spacer 6 on the rotating shaft 3, press the two ends of the snap-on spacer 6 to fix the left half spacer 61 and the right half spacer 62 through the snap-on structure, ensuring the stability of the snap-on spacer 6 installed on the rotating shaft 3 and preventing the snap-on spacer 6 from falling off.

[0037] In addition, a keyway 627 is provided on the inner wall of the right half spacer 62 , which is key-connected to the rotating shaft 3 so that the buckle spacer 6 rotates together with the rotating shaft 3 .

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that the first clip 612 and the second clip groove 614 are arranged on the edge of the inner wall close to the front clip protrusion 611, and the second clip 622 and the first clip groove 624 are both arranged on the edge of the inner wall close to the rear clip protrusion 621, so that the first clip 612 and the second clip 622 are embedded in the clip spacer 6, thereby realizing the positioning of the edges of the left half spacer 61 and the right half spacer 62 in the radial direction of the rotating shaft 3, and avoiding the edge of the connection between the left half spacer 61 and the right half spacer 62 from curling up during rotation.

[0040] In addition, a first inclined surface 613 is provided on the side of the first clip 612 near the second slot 614, causing the width of the first clip 612 to gradually decrease toward the end. A second inclined surface 623 is provided on the side of the second clip 622 near the first slot 624, causing the width of the second clip 622 to gradually decrease toward the end. During the installation of the left and right half spacers 61 and 62, the first and second inclined surfaces 613 and 623 serve as guides, facilitating the insertion of the first clip 612 into the first slot 624 and the second clip 622 into the second slot 614.

[0041] A third latch 615 is provided on the right side wall of the front latch 611, near the inner edge. Third slots 626, which mate with the third latch 615, are provided on both sides of the inner edge of the front half of the right half of the spacer 62. Fourth latches 625 are provided on the left side wall of the rear latch 621, near the inner edge. Fourth slots 616, which mate with the fourth latch 625, are provided on both sides of the inner edge of the rear half of the left half of the spacer 61. By engaging the third latch 615 with the third slot 626 and the fourth latch 625 with the fourth slot 616, the radial positioning of the connection between the left and right half spacers 61 and 62 can be further strengthened.

[0043] A roller die side pressure roller comprises a bracket 1, two baffles 2, a rotating shaft 3, two end stop wheels 4, and four snap-on spacer sleeves 6 according to the first or second embodiment. The upper sides of the two baffles 2 are fixed to the sides of the bracket 1 by bolts, and the ends of the rotating shaft 3 are connected to the lower sides of the two baffles 2 by bearings. The two end stop wheels 4 and the snap-on spacer sleeves 6 are both mounted on the rotating shaft 3 and located between the two baffles 2. The four snap-on spacer sleeves 6 are sequentially arranged between the two end stop wheels 4. The two end stop wheels 4 press against the ends of the snap-on spacer sleeves 6, and the two baffles 2 press against the outer ends of the two end stop wheels 4.

[0044] To replace the snap-on spacer 6, simply loosen the two baffles 2 and move them to the sides, slightly increasing the distance between them. Then, move the left half of the spacer 61 forward and the right half of the spacer 62 backward, staggering them, and then remove them.

[0045] Stagger the new left and right half spacers 61, 62 on either side of the rotating shaft 3. Then, move the left and right half spacers 61, 62 closer together until they are locked in place by the snap mechanism. Then, tighten the two baffles 2 so that they press against the snap spacer 6 via the two end stop rollers 4, completely securing the snap spacer 6.

[0046] Therefore, the snap-on spacer 6 is easy to disassemble and install, and is convenient for replacement.
