Description

Technical Field

[0001] This utility model relates to the field of transmission rollers, and in particular to a detachable transmission roller. Background Technology

[0002] In material conveying systems, drive rollers are common conveying components, widely used in assembly lines, conveyor belts, and other equipment. Traditional drive rollers typically employ an integral structure, meaning the roller shaft and roller are integrally formed or fixedly connected. In actual use, the rollers are prone to wear due to long-term contact and friction with materials. Once the wear reaches a certain level, the entire drive roller needs to be removed from the equipment and replaced. However, drive rollers often have a significant mass, making the replacement process complex and time-consuming. Utility Model Content

[0003] The purpose of this invention is to provide a detachable transmission roller to solve the problem in the prior art that the roller shaft needs to be removed and replaced together when the roller is worn.

[0004] The technical solution of this utility model is: a detachable transmission roller, including a roller shaft, with rollers separately provided at both ends of the roller shaft, and the rim of the rollers being used to contact the material; Driven by the transmission mechanism, the roller can drive the roller to rotate around its own axis. When multiple rollers are arranged in parallel, the material that comes into contact with the roller can be conveyed in the direction of the arrangement of multiple rollers. The roller shaft connects the rollers through the roller shaft along the axis of the roller shaft. One end face of the roller shaft is constructed as a first connecting surface, and the end face of the roller on the same side as the first connecting surface is constructed as a second connecting surface. The roller and the roller shaft are detachably connected by a connector, and the two ends of the connector at the installation position correspond to the first connecting surface and the second connecting surface, respectively.

[0005] Preferably, the connector is configured as a sheet structure, having a plane parallel to the roller shaft and the end face of the roller in the installation position; The connector has through holes at both ends perpendicular to its own plane. The first connecting surface and the second connecting surface have connecting holes corresponding to the through holes. Fasteners that pass through a pair of through holes and connect to the corresponding connecting holes fix the connector, roller and roller shaft.

[0006] Preferably, the connectors are evenly arranged in a plurality of configurations around the axis of the roller or wheel, and any connector in the installation position has a length direction arranged radially along the roller or wheel.

[0007] Preferably, the through holes are distributed in multiple ways along the length of the connector at at least one end of the connector, and the multiple through holes can be combined to form a waist-shaped groove.

[0008] Preferably, the transmission mechanism includes a transmission wheel, which is coaxially disposed in the middle section of the roller shaft and has a diameter smaller than that of the roller. The rim of the transmission wheel has a toothed structure, and a transmission belt is provided to cooperate with the transmission wheel, and the transmission belt is engaged with the transmission wheel.

[0009] Preferably, the roller includes a wheel body and a rubber coating. The rubber coating is formed on the rim of the wheel body by a casting process. The rim of the wheel body has a protruding engaging portion, and the rubber coating is formed between a pair of engaging portions.

[0010] Compared with the prior art, the advantages of this utility model are: (1) In this application, the roller and the roller shaft are connected separately and detachably. When the roller is worn, the roller can be replaced separately without removing the entire roller shaft from the equipment, which significantly reduces maintenance costs and material waste.

[0011] (2) This application uses sheet-like connectors and fasteners to fix the rollers and roller shafts axially to prevent them from moving axially during operation; multiple connectors are evenly arranged circumferentially and the connection strength is enhanced by multiple sets of through holes and connecting holes, which further improves the stability and durability of the structure.

[0015] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0016] like Figure 1 - Figure 3 As shown, a detachable transmission roller includes a roller shaft 1, with rollers 2 separately mounted at both ends of the roller shaft 1. The rims of the rollers 2 can abut against the material. The roller shaft 1 can rotate around its own axis under the drive of a transmission component. When multiple roller shafts 1 are arranged in parallel, the rollers 2 at both ends can form a mounting surface for the material, and the material abutting against them is conveyed towards the direction of the roller shafts 1.

[0017] The separate connection between roller 2 and roller shaft 1 allows roller 2 to be removed from the equipment without removing roller shaft 1 when roller 2 wears out after long-term use. Roller 2 can be removed from roller shaft 1 axially and repaired or replaced separately.

[0018] Roller 1 connects roller 2 through roller 2 along the axis of roller 2. One end face of roller 1 is constructed as a first connecting surface, and the end face of roller 2 on the opposite outer side of its mounting position on roller 1, corresponding to the first connecting surface, is constructed as a second connecting surface. To ensure that the separately configured roller 2 will not detach from roller 1 axially during operation, a connector 3 is provided in this embodiment to detachably connect roller 1 and roller 2. In the installation position of connector 3, both ends of connector 3 are respectively positioned corresponding to the first connecting surface and the second connecting surface.

[0019] Specifically, the connector 3 is configured as a sheet structure, and in the installation position, its plane is parallel to the end faces of the roller shaft 1 and the roller 2. The connector 3 has through holes 31 perpendicular to its own plane at both ends. The first connecting surface and the second connecting surface have two connecting holes 11 corresponding to the two through holes 31. Fasteners are provided that pass through a pair of through holes 31 and connect to the corresponding connecting holes 11 to fix the connector 3 and the roller 2 to the roller shaft 1, thereby limiting the relative axial movement of the roller 2 and the roller shaft 1 through the connector 3.

[0020] Preferably, to improve the connection strength between the connector 3 and the roller shaft 1 and the roller 2, in this embodiment, multiple connectors 3 are uniformly arranged around the axis of the roller shaft 1 or the roller 2, and any connector 3 has a length direction along the radial direction of the roller shaft 1 or the roller 2 in its installation position. Further, in a preferred embodiment of this application, multiple through holes 31 are formed at both ends of the connector 3 along the length direction of the connector 3, and the multiple through holes 31 combine to form a waist-shaped groove 32. Correspondingly, multiple connecting holes 11 on the first connecting surface and the second connecting surface are arranged radially.

[0021] The transmission mechanism includes a transmission wheel 4, which is fixed to the middle section of the roller shaft 1. A transmission belt is installed in conjunction with the transmission wheel 4. When multiple roller shafts 1 are arranged in parallel, the transmission belt is fitted onto the transmission wheels 4 mounted on the roller shafts 1 at both ends. Furthermore, the rim of the transmission wheel 4 has a toothed structure, and the inner wall of the transmission belt also has a toothed structure. One of the roller shafts 1 is connected to a power unit, which drives the other roller shafts 1 through the meshing action of the transmission belt.

[0022] The roller 2 includes a wheel body 21 and a rubber coating 22. The rubber coating 22 is formed on the rim of the wheel body 21 by a casting process to increase the frictional driving force on the material when the roller 2 comes into contact with the material. To prevent the rubber coating 22 from falling off the wheel body 21 or slipping, in this embodiment, a locking part 23 is provided protruding on the rim of the wheel body 21. The rubber coating 22 is formed between a pair of locking parts 23, making it difficult for the rubber coating 22 to fall off the wheel body 21 axially.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
