Description

Technical Field

[0001] This utility model relates to the field of conical roller technology, and specifically discloses a split-type splicing anti-slip conical roller. Background Technology

[0002] In industries such as logistics conveying, production line assembly, and packaging sorting, conical rollers (commonly known as "conical rollers") are a key component, widely used in equipment such as turning machines, centering machines, and sorting machines. By arranging multiple conical rollers according to a specific pattern and utilizing their linear velocity differences, the conveying direction of goods can be changed smoothly and efficiently, or the goods can be positioned.

[0003] Currently, most tapered rollers on the market are of integral structure. Integral rollers are cumbersome to disassemble and assemble. When a part of the roller is worn or damaged, the entire roller needs to be removed from the equipment and replaced as a whole, which not only increases maintenance time but also leads to high maintenance costs. At the same time, traditional tapered rollers have poor anti-slip performance and are prone to wear. Therefore, a split splicing anti-slip tapered roller is needed to solve this problem. Utility Model Content

[0004] This invention proposes a split-type splicing anti-slip conical roller. By disassembling the roller body into several structurally identical split roller sleeves, it achieves rapid splicing and positioning of adjacent split roller sleeves, and can complete assembly or disassembly without complicated tools. When the roller body is partially worn or damaged, only the damaged split roller sleeve needs to be replaced, without replacing the entire roller body. The anti-slip sleeve has strong wear resistance, and the raised anti-slip patterns or particles on the outer surface provide a stable anti-slip effect.

[0005] This utility model is implemented as follows: a split-type spliced ​​anti-slip conical roller includes a central shaft and a roller body. The roller body is formed by splicing several split roller sleeves with the same structure along the axial direction of the central shaft, and the outer wall of the spliced ​​roller body is conical.

[0006] Each of the split roller sleeves has an inner bushing fixedly connected to one end. The outer wall of the inner bushing is fixedly connected to a plurality of wedge blocks distributed along the circumference. The other end of each of the split roller sleeves is provided with a wedge groove that matches the wedge block. Two adjacent split roller sleeves achieve circumferential limiting and radial positioning by inserting the wedge block into the wedge groove.

[0007] The outer wall of the roller is bonded with an outer anti-slip sleeve, and the outer surface of the outer anti-slip sleeve is provided with raised anti-slip patterns or particles.

[0008] As a preferred embodiment of the present invention, the central shaft is a spline shaft, and the inner walls of the split roller sleeve and the inner liner are provided with spline grooves that cooperate with the spline shaft. The spline grooves and wedge grooves are arranged alternately.

[0009] As a preferred embodiment of the split-type splicing anti-slip conical roller of this utility model, the outer anti-slip sleeve is made of polyurethane, rubber or engineering plastic.

[0010] As a preferred embodiment of the present invention, the outer wall of the split-type splicing anti-slip conical roller is threaded with a countersunk bolt. The threaded end of the countersunk bolt passes through the split roller sleeve and the inner bushing in sequence and is threadedly connected to the central shaft, thereby pressing and fixing the split roller sleeve onto the central shaft.

[0011] As a preferred embodiment of the split-type spliced ​​anti-slip conical roller of this utility model, the inner liner and the split roller sleeve are integrally formed.

[0012] The beneficial effects of this utility model are:

[0013] 1. By disassembling the roller body into several structurally identical split roller sleeves, the quick splicing and positioning of adjacent split roller sleeves can be achieved by interlocking wedge blocks and wedge grooves, and assembly or disassembly can be completed without complicated tools; when the roller body is partially worn or damaged, only the damaged split roller sleeve needs to be replaced, without replacing the entire roller body, which greatly shortens the maintenance time and reduces the maintenance cost.

[0014] 2. The outer anti-slip sleeve bonded to the outer wall of the roller is made of polyurethane, rubber or engineering plastic. These materials are highly wear-resistant, and the raised anti-slip patterns or particles on the outer surface can provide a stable anti-slip effect. Compared with the traditional patterns directly processed on the outer wall of the roller, the anti-slip sleeve is easier to replace. The anti-slip performance can be maintained by regularly replacing the anti-slip sleeve, thus extending the overall service life of the roller. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A split-type spliced ​​anti-slip conical roller includes a central shaft 1 and a roller body. The roller body is formed by splicing several split roller sleeves 2 with the same structure along the axial direction of the central shaft 1, and the outer wall of the spliced ​​roller body is conical.

[0023] Each split roller sleeve 2 has an inner bushing 201 fixedly connected to one end. The outer wall of the inner bushing 201 is fixedly connected to a plurality of wedge blocks 202 distributed along the circumference. Each split roller sleeve 2 has a wedge groove 204 adapted to the wedge block 202 at the other end. Two adjacent split roller sleeves 2 achieve circumferential limiting and radial positioning by inserting the wedge block 202 and the wedge groove 204.

[0024] The outer wall of the roller is bonded with an outer anti-slip sleeve 3, and the outer surface of the outer anti-slip sleeve 3 is provided with raised anti-slip patterns or particles.

[0025] In this embodiment, the traditional integral conical roller is decomposed into multiple standard split roller sleeves 2. During splicing, the wedge block 202 on one split roller sleeve 2 is precisely inserted into the wedge groove 204 of the adjacent split roller sleeve 2. The insertion of the wedge block 202 and the wedge groove 204 realizes the rapid splicing and positioning of the adjacent split roller sleeves 2. Assembly or disassembly can be completed without complex tools. Moreover, the cooperation between the wedge block 202 and the wedge groove 204 realizes radial positioning and circumferential limiting, ensuring that all split roller sleeves 2 form a conical roller with high coaxiality and smooth operation after splicing. When the roller body is worn or damaged, it is not necessary to replace the entire roller body, but only to replace the damaged split roller sleeve 2, saving maintenance costs and time.

[0026] The outer anti-slip sleeve 3 bonded to the outer wall of the roller has strong wear resistance, and the raised anti-slip patterns or particles on the outer surface can provide a stable anti-slip effect. Compared with the traditional patterns directly processed on the outer wall of the roller, the anti-slip sleeve is easier to replace. The anti-slip performance can be maintained by regularly replacing the anti-slip sleeve, thus extending the overall service life of the roller.

[0027] As a technical optimization of this utility model, the central shaft 1 is a spline shaft, and the inner walls of the split roller sleeve 2 and the inner bushing 201 are provided with spline grooves 203 that cooperate with the spline shaft. The spline grooves 203 and the wedge grooves 204 are staggered.

[0028] In this embodiment, the spline shaft and spline groove 203 cooperate to provide a power transmission path. Power is directly transmitted from the spline shaft to each split roller sleeve 2 through the spline connection.

[0029] As a technical optimization of this utility model, the outer anti-slip sleeve 3 is made of polyurethane, rubber or engineering plastic.

[0030] In this embodiment, the outer anti-slip sleeve 3 is made of polyurethane, rubber or engineering plastic, which can provide a durable and stable anti-slip effect and a long service life.

[0031] As a technical optimization of this utility model, the outer wall of the split roller sleeve 2 is threaded with a countersunk bolt. The threaded end of the countersunk bolt passes through the split roller sleeve 2 and the inner bushing 201 in sequence and is threadedly connected to the central shaft 1, thereby pressing and fixing the split roller sleeve 2 onto the central shaft 1.

[0032] In this embodiment, the split roller sleeve 2 can be pressed onto the central shaft 1 by countersunk bolts, providing a second layer of fastening protection.

[0033] As a technical optimization of this utility model, the inner liner 201 and the split roller sleeve 2 are integrally formed.

[0034] In this embodiment, the inner bushing 201 and the split roller sleeve 2 are integrally formed, which improves the structural strength and integrity of the component.

[0035] The working principle and usage process of this utility model are as follows: First, install the central shaft 1 in the preset position of the equipment. Then, take the split roller sleeves 2 one by one. Align the first split roller sleeve 2 with the central shaft 1 (spline shaft) through the inner wall spline groove 203 and fit it in, so that the spline groove 203 and the spline shaft are precisely matched. Next, take the next split roller sleeve 2 and align the wedge block 202 at one end with the wedge groove 204 at the other end of the previous split roller sleeve 2. Insert it axially to achieve insertion (the wedge block 202 and the wedge groove 204 complete the circumferential limit and radial positioning). At the same time, ensure that the spline groove 203 of the split roller sleeve 2 is adapted to the central shaft 1. In this way, all the split roller sleeves 2 are spliced ​​in sequence to form a complete conical roller body. Finally, through the countersunk bolts on the outer wall of the split roller sleeve 2, the threaded end is passed through the split roller sleeve 2 and the inner bushing 201 and then threadedly connected to the central shaft 1 to achieve the clamping and fixing of the split roller sleeve 2 and the central shaft 1, and the assembly is completed.

[0036] When the equipment is running, power is input to the central shaft 1 (spline shaft). The central shaft 1 directly and synchronously transmits power to each split roller sleeve 2 through the spline and the spline groove 203 on the inner wall of the inner bushing 201. At the same time, adjacent split roller sleeves 2 are prevented from rotating relative to each other through the circumferential limiting effect of the wedge block 202 and the wedge groove 203, ensuring that all split roller sleeves 2 rotate synchronously with the central shaft, thereby achieving stable power output or material conveying.

[0037] When wear occurs in a part of the roller body (such as damage to the outer anti-slip sleeve 3 or the split roller sleeve 2), simply unscrew the countersunk bolts at the corresponding positions, pull out the damaged split roller sleeve 2 axially (separating the wedge block 202 from the wedge groove 203), replace the new split roller sleeve 2, and then re-fix it. There is no need to disassemble the entire roller body, making the operation simple and efficient.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
