DETAILED DESCRIPTION

[0026] The specific embodiments of the present application will be described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0027] In the present application, unless otherwise stated, the orientation words contained in the terms such as "up, down, in, out" only represent the orientation of the term in the conventional use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0028] As Figures 1-4As shown, a quick disassembly structure of a compression roller comprises a mounting ring 2 coaxially mounted on the end of the compression roller through a plurality of mounting bolts 1, an adjustable limiting sleeve 3 detachably connected with the mounting ring 2 and coaxially arranged with the mounting ring 2, and a replaceable limiting ring 4, a plurality of first clamping grooves 5 are arranged on the end of the limiting sleeve 3 away from the mounting ring 2, a first clamping block 6 matching the first clamping groove 5 is protruded on one side of the limiting ring 4, and a ring-shaped flange 7 capable of abutting against the inner ring of the bearing is coaxially protruded on the other side of the limiting ring 4.

[0029] The mounting ring 2 can be mounted on the end of each compression roller through the mounting bolt 1, so that the mounting ring does not need to be disassembled and mounted when the compression roller is replaced, and the replacement efficiency is improved.

[0030] When the compression roller needs to be replaced, the bearing is disassembled from the end of the compression roller, and the limiting sleeve 3 is separated from the mounting ring 2; the disassembled limiting sleeve 3 is sleeved on the end of the compression roller to be mounted, and the bearing is sleeved on the end of the compression roller; after the bearing is assembled on the split bearing seat, the length of the limiting sleeve 3 is adjusted so that the ring-shaped flange 7 on the limiting ring 4 abuts against the inner ring of the bearing; the structure is used on both ends of the compression roller to prevent the end of the compression roller from sliding inside the inner ring of the bearing during rotation of the compression roller.

[0031] During assembly of the bearing on the bearing seat, the compression roller is lifted by a crane; when the position of the bearing deviates from the bearing seat, the bearing is pushed to slide on the end of the compression roller to adjust the position of the bearing; after the bearing is assembled on the bearing seat, the length of the limiting sleeve 3 is adjusted so that the ring-shaped flange 7 abuts against the inner ring of the bearing; since the length of the limiting sleeve 3 can be adjusted, the negative effects caused by the position change of the bearing during assembly can be eliminated, which is beneficial to assembly of the bearing.

[0032] Since the diameters of the ends of different compression rollers are different, bearings of different specifications are used; at this time, the limiting ring 4 on the limiting sleeve 3 is disassembled, and a corresponding limiting ring 4 is replaced; the first clamping block 6 on the other limiting ring 4 is inserted into the corresponding first clamping groove 5, so that the limiting ring 4 and the limiting sleeve 3 are connected together; the structure can be used on compression rollers of different specifications, and has wide applicability.

[0033] The limiting sleeve 3 comprises a first sleeve 8 and a second sleeve 9 coaxially arranged with the first sleeve 8 and threadedly sleeved outside the first sleeve 8, and the first clamping groove 5 is located on the end of the second sleeve 9.

[0034] After the first sleeve 8 is connected with the mounting ring 2, the second sleeve 9 is rotated to adjust the distance between the two ends of the limiting sleeve 3.

[0035] The first annular positioning flange 10 is coaxially protruded on one side of the limiting ring sheet 4 close to the limiting sleeve 3 and can be inserted into the end of the second sleeve 9.

[0036] When the limiting ring sheet 4 is replaced, the second annular positioning flange 12 can be inserted into the end of the second sleeve 9, and the first clamping block 6 is inserted into the first clamping slot 5, thereby improving the clamping stability between the limiting ring sheet 4 and the second sleeve 9.

[0037] The second clamping block 11 is protruded on one side of the mounting ring 2 close to the limiting sleeve 3 and is uniformly distributed in the circumferential direction. The second annular positioning flange 12 is coaxially protruded on one side of the mounting ring 2 close to the limiting sleeve 3. The end of the first sleeve 8 is recessed with an annular clamping slot 13 matched with the second annular positioning flange 12. The end of the first sleeve 8 is recessed with a second clamping slot 14 matched with the second clamping block 11.

[0038] When the limiting sleeve 3 needs to be disassembled, the limiting sleeve 3 is pushed away from the mounting ring 2 along the axial direction of the first sleeve 8, so that the second clamping block 11 and the second clamping slot 14 are separated, and the second annular positioning flange 12 and the annular clamping slot 13 are separated. When the limiting sleeve 3 is assembled, the limiting sleeve 3 is rotated or shaken to continuously adjust the positions of the second clamping slot 14 and the annular clamping slot 13, so that the second clamping block 11 can be inserted into the second clamping slot 14, and the second annular positioning flange 12 can be inserted into the annular clamping slot 13. The disassembly and assembly operations of the limiting sleeve 3 are simple and convenient.

[0039] The cooperation between the second annular positioning flange 12 and the annular clamping slot and the cooperation between the second clamping block 11 and the second clamping slot 14 can improve the clamping stability between the first sleeve 8 and the mounting ring 2.

[0040] The number of mounting bolts 1 is at least three, and the three mounting bolts 1 are uniformly distributed in the circumferential direction of the mounting ring 2. Each mounting bolt 1 is threadedly passed through the mounting ring 2 in the corresponding radial direction of the mounting ring 2.

[0041] The end of the mounting bolt 1 tightly abuts against the outer wall of the end of the compression roller, so that the mounting ring 2 can be fixed, and the mounting ring 2 can be assembled on the end of different compression rollers. When the diameter of the end of the compression roller is smaller than the inner diameter of the mounting ring 2, the mounting ring 2 can be assembled on the end of the compression roller.

[0042] The outer wall of the end of the compression roller is recessed with a mounting groove matched with the mounting bolt 1.

[0043] The mounting groove can improve the mounting strength and stability of the mounting ring 2.

[0044] The outer wall of the second sleeve 9 is provided with an anti-skid pattern 15.

[0045] The anti-skid lines 15 facilitate the rotation of the second sleeve 9 by a person.

[0046] The second sleeve 9 is provided with a multi-angle protruding part 16 at the end away from the first clamping slot 5.

[0047] A handle tool can be used to clamp the multi-angle protruding part 16 to rotate the second sleeve 9.

[0048] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0049] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not further describe various possible combinations.
