[0017] In order to make the utility model purposes, technical schemes and advantages more clearly, the following will be further described in detail with the drawings and examples.

[0018] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of replaceable cylinder skin's roller structure for roller conveyor, including the device pipe 1 being set transversely and both ends are open, rotatingly connected with coaxial rotating shaft 2 in the inside of device pipe 1, the outer surface of device pipe 1 is equipped with multiple semicircular notches 5, the outer surface of device pipe 1 is fixedly connected with first connecting piece 3 in one side and between each slot 5, the outer surface of multiple first connecting pieces 3 is fixedly connected with the semicircular first ring block 4 of coaxial with device pipe 1, the outer surface of rotating shaft 2 and the position of multiple slots 5 are fixedly connected with second connecting piece 6 respectively extended outward through multiple slots 5, the outer surface of multiple second connecting pieces 6 is fixedly connected with second ring block 7, which is same with the first ring block 4 in specification shape and is set mutually symmetrical along horizontal plane direction.

[0019] In the embodiment, when the cylinder skin needs to be replaced, rotating the rotating shaft 2 drives the second connecting piece 6 and the second ring block 7 to rotate synchronously until the multiple first ring blocks 4 and the second ring blocks 7 overlap each other. At this time, the roller body as a whole is semicircular, so it will not limit the cylinder skin. Then the old cylinder skin can be disassembled and a new cylinder skin can be sleeved. Then the rotating shaft 2 is rotated again until the first ring block 4 and the second ring block 7 are mutually symmetrical. At this time, the roller body is cylindrical and can support and fix the cylinder skin. In this way, the replacement of the cylinder skin can be completed. After the cylinder skin is worn out, the entire roller body does not need to be replaced, saving cost.

[0020] Further, the outer surfaces of the device pipe 1 and the rotating shaft 2 are both provided with plug holes 9 corresponding to each other along the diametric direction of the cross section. When the two plug holes 9 at both ends are aligned, the multiple first ring blocks 4 and the second ring blocks 7 overlap each other or are mutually symmetrical.

[0021] The inner part of the two plug holes 9 at both ends is detachably installed with a plug 10.

[0022] In the embodiment, after the plug 10 is inserted into the inner part of the plug hole 9 at both ends, the rotating shaft 2 can be limited and fixed, so that it cannot rotate freely. When the cylinder skin needs to be replaced, the plug 10 is pulled out from the inner part of the plug hole 9 in advance. The outer surface of the plug 10 is provided with a spring piece structure that is outwardly supported. The plug 10 can be fixed in the plug hole 9 by friction force, preventing the plug 10 from falling naturally when the roller body rotates.

[0023] Further, the outer surface of one end of the device pipe 1 is fixedly connected with a sprocket 8.

[0024] In the embodiment, the sprocket 8 is a transmission structure between a plurality of rollers, which is a prior art and will not be described here.

[0025] Further, the torsion block 11 is fixedly connected to one end surface of the rotating shaft 1.

[0026] The torsion block 11 is coaxial with the rotating shaft 1 and has an outer surface provided with anti-skid lines.

[0027] In the embodiment, the torsion block 11 facilitates people to rotate the rotating shaft 2, and the anti-skid lines on the surface of the torsion block 11 have an anti-skid effect.

[0028] The working principle and use process of the utility model are as follows: after the utility model is installed, when it is necessary to replace the drum skin, the rotating shaft 2 is rotated to drive the second connecting plate 6 and the second ring block 7 to rotate synchronously until the plurality of first ring blocks 4 and the second ring block 7 overlap with each other, at this time, the roller body is in a semicircular shape, so that the drum skin is not limited, then the old drum skin can be disassembled and a new drum skin can be sleeved, then the rotating shaft 2 is rotated again until the first ring block 4 and the second ring block 7 are in a symmetrical state, at this time, the roller body is in a cylindrical shape and can support and fix the drum skin, so that the replacement of the drum skin can be completed, and after the drum skin is worn, the entire roller body does not need to be replaced, so that the cost is saved.

[0029] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
