The reasonable structure of the first pull rod 315 on the first right-angle push rod 312, the second pull rod 326 on the second right-angle push rod 322, and the third pull rod 336 on the third right-angle push rod 332 enables the first support component 31 and the first groove 11, the second support component 32 and the second groove 12, the third support component 33 and the third groove 13, and the fourth support component 34 and the fourth groove 14 to work in sequence, so as to satisfy the requirement that the depths of the first groove 11, the second groove 12, the third groove 13, and the fourth groove 14 on the inner end surface of the cylinder 10 become gradually shallower, and the wear of the roller 100 is gradually worn inward from the outer end surface of the cylinder 10, that is, the first right-angle push rod 312 of the first support component 31 on the roller 100 of the embodiment first penetrates through the first groove 11 on the cylinder 10, then the second right-angle push rod 322 on the second support component 32 penetrates through the second groove 12 on the cylinder 10, then the third right-angle ejector 323 on the third support component 33 penetrates through the third groove 13 on the cylinder 10, finally the ejector 342 on the fourth support component 34 penetrates through the fourth groove 13 on the cylinder 10, and the corresponding cylinder 10 surface of the roller 100 is worn to different degrees.

It can be understood that the part of the conveyor belt 200 wrapping the roller 100 can press the outer end surface of the cylinder 10 on the roller 100, and the part of the first right-angle ejector rod 312 protruding out of the first groove 11 can be pushed to compress the first spring 313 and enter the cylinder 10, or the part of the second right-angle ejector rod 322 protruding out of the second groove 12 can be pushed to compress the second spring 323 and enter the cylinder 10, or the part of the third right-angle ejector rod 332 protruding out of the third groove 13 can be pushed to compress the third spring 333 and enter the cylinder 10, or the part of the ejector rod 342 protruding out of the fourth groove 14 can be pushed to compress the fourth spring 343 and enter the cylinder 10; and the conveyor belt 200 is not wrapped around the roller 100, the first right-angle push rod 312 is driven by the first spring 313 to extend out of the first groove 11 of the cylinder 10, the second right-angle push rod 322 is driven by the second spring 323 to extend out of the second groove 12 of the cylinder 10, the third right-angle push rod 332 is driven by the third spring 333 to extend out of the third groove 13 of the cylinder 10, or the push rod 342 is driven by the fourth spring 343 to extend out of the fourth groove 14 of the cylinder 10. When the roller 100 is wrapped by the transmission belt 200, the transmission belts 200 at different positions are in contact with the roller 100, the ejection force of the transmission belt 200 to the barrel 10 of the roller 100 is different, and thus, along with the rotation of the roller 100, the part extending out of the barrel 10 on the roller 100 extends and contracts the transmission belt 200, so that when people judge the abrasion condition of the roller 100, the quantity of the transmission belts 200 protruding out of the roller 100 can be intuitively determined, the barrel 10 extending out of the roller 100 by a plurality of supporting components is obtained, and then the thickness of the barrel 10 and the depth of the groove formed in the barrel 10 are utilized, so that the abraded thickness of the roller 100 is indirectly judged.

In summary, the roller provided by the invention has the advantages that through the reasonable structural arrangement, when the roller is used, the abrasion condition of the surface of the roller can be visually judged by extending the supporting component part out of the roller body.
