[0022] The following further describes the present utility model with reference to the drawings.
[0023] Refer to Figures 1-6 As shown, the high-wear-resistant grooved roller includes an inner roller body 1 and an outer roller body 2. The outer roller body 2 is detachably arranged on the outer surface of the inner roller body 1. A first limit block 3 is arranged on one side of the inner roller body 1. The first limit block 3 is integrally formed with the inner roller body 1. A second limit block 4 is detachably arranged on the other side of the inner roller body 1. A connection bushing 401 is arranged on the side of the second limit block 4 away from the outer roller body 2. Connection bolts 402 fixedly connected to the inner roller body 1 are annularly arranged on the connection bushing 401. The second limit block 4 is detachably connected to the outer roller body 2 through the connection bolts 402 and the connection bushing 401. By disassembling the second limit block 4, the outer roller body 2 can be disassembled from the inner roller body 1.
[0024] The side walls of the first limit block 3 and the second limit block 4 are in contact with the side wall of the outer roller body 2. The first limit block 3 and the second limit block 4 cooperate with each other to limit the axial movement of the outer roller body 2, making its integrity with the inner roller body 1 better. A plurality of positioning columns 5 are annularly arranged on the side of the first limit block 3 and the second limit block 4 close to the outer roller body 2. A positioning groove 6 matching the positioning columns 5 is formed on the side wall of the outer roller body 2. The positioning columns 6 and the positioning groove 6 cooperate with each other to form a connection between the outer roller body 2 and the first limit block 3 and the second limit block 4, so as to limit the radial movement of the outer roller body 2 and make the integrity among the first limit block 3, the second limit block 4, the outer roller body 2, and the inner roller body 1 better.
[0025] The positioning post 5 is provided with a first connection hole 501. A second connection hole 201 communicating with the first connection hole 501 is provided on the side wall of the outer roller body 2. A third connection hole 701 communicating with the first connection hole 501 is provided on the first limiting block 3 and the second limiting block 4. The third connection hole 701, the second connection hole 201, and the first connection hole 501 are on the same central axis and communicate with each other. A clamping component is arranged on the positioning post 5. A clamping groove 601 matching with the clamping component is arranged inside the positioning groove 6. Fixing bolts 8 are arranged on the first limiting block 3 and the second limiting block 4. The fixing bolts 8 sequentially pass through the third connection hole 701, the first connection hole 501 and are in threaded connection with the second connection hole 201. And the fixing bolts 8 drive the clamping component to form a clamping with the clamping groove 601. When the clamping component forms a connection with the fixing bolts 8, it forms a clamping with the clamping groove, making the connection strength between the positioning post 5 and the positioning groove 6 higher. The cooperation between the fixing bolts 8 and the clamping component further improves the integrity among the first limiting block 3, the second limiting block 4, the outer roller body 2, and the inner roller body 1. And by disassembling the fixing bolts 8, the clamping component, and the second limiting block 4, the outer roller body 2 can be disassembled from the inner roller body 1. After wear occurs on the roller surface of the outer roller body, the outer roller body can be replaced separately without replacing the whole unit.
[0026] The clamping component includes a through hole 901, a sliding groove 902, a clamping block 903, a sliding block 904, and a spring 905. The through holes 901 are symmetrically arranged on the inner walls at both ends of the first connection hole 501 and communicate with the clamping groove 601. The sliding grooves 902 are symmetrically arranged on the inner walls on both sides of the through hole 901. The clamping block 903 is movably arranged inside the through hole 901. The sliding blocks 904 are arranged on both sides of the clamping block 903 and are slidably connected with the sliding grooves 902. The spring 905 is sleeved on one end of the clamping block 903 close to the clamping groove 601. One end of the spring 905 abuts against the sliding block 904, and the other end abuts against the inner wall of the sliding groove 902. When the fixing bolt 8 does not enter the first connection hole 501, under the action of the force of the spring 905, one end of the clamping block 903 is located inside the first connection hole 501, and the other end is located inside the through hole 901. When the fixing bolt 8 enters the first connection hole 501, it forms a squeeze on the clamping blocks 903 on both sides, causing the clamping block 903 to move along the sliding groove 902 towards the clamping groove 601 through the sliding block 904, and forming a squeeze on the spring 905, making it elastically deformed, and making the clamping block 903 engage with the clamping groove 601. And restricted by the fixing bolt 8, the clamping block 903 cannot be reset, making it continuously engage with the clamping groove 601, thereby making the connection strength between the positioning post 6 and the positioning groove 6 higher. When replacing the outer roller body 2, after the fixing bolt 8 is removed from the first connection hole 501, the force that the clamping block 903 is squeezed disappears, the spring 905 rebounds, driving the clamping block 903 to reset and separating it from the clamping groove 601.
[0027] One end of the clamping block 903 away from the clamping groove 601 is provided with a first driving inclined surface 906, and one end of the fixing bolt 8 connected to the second connection hole 201 is provided with a second driving inclined surface 801 matching the first driving inclined surface 906. The second driving inclined surface 801 of the fixing bolt 8 first contacts the first driving inclined surface 906 of the clamping block 903, so as to drive the clamping block 903 to move towards one end of the clamping groove 601.
[0028] A plurality of convex blocks 101 are equally divided and arranged on the outer surface of the inner roller body 1 in a circumferential manner. Grooves 202 matching the convex blocks 101 are formed on the inner wall of the outer roller body 2. The grooves 202 and the positioning grooves 6 are arranged alternately. The convex blocks 101 and the grooves 202 cooperate with each other to further improve the integrity between the inner roller body 1 and the outer roller body 2, making their connection more firm and stable.
[0029] Wear-resistant patterns 203 are uniformly arranged on the outer surface of the outer roller body 2. The wear-resistant patterns 203 are uniformly arranged annular grooves, which effectively increase the extrusion and stress area of the outer roller body 2 under the same projected area, making its working efficiency higher and wear resistance better.
[0030] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
