Description

Technical Field

[0001] This utility model relates to the field of roller assembly technology, and in particular to a roller assembly for transporting materials. Background Technology

[0002] In the Tianrui multi-station cutting machine, the roller assembly used for transporting materials mainly consists of a shaft and roller bodies mounted on the shaft. The shaft is primarily used to transmit torque and speed to the roller bodies, which in turn transport the material mounted on them through the rotation of the shaft, causing changes in the material's displacement. To reduce wear on the material from the roller bodies during transport, a rubber sleeve is typically fitted onto the outer wall of the roller bodies. This rubber sleeve, due to its good wear resistance and cushioning properties, can protect the contact surface between the material and the roller bodies from direct wear and scratches.

[0003] However, during use, it was found that because the material is in direct contact with the inclined surface of the roller body during transportation, the roller rubber will gradually delaminate and deform under pressure over time, moving away from the roller body along the shaft and accumulating on the bearing seat block to some extent. In practical applications, once the roller rubber is deformed, the entire roller body needs to be replaced, which leads to a significant increase in cost. Utility Model Content

[0004] The purpose of this invention is to provide a roller assembly for transporting materials, so as to solve the problems mentioned in the background art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] Given that the roller rubber on the roller body in the existing technology is easily deformed and detached after being subjected to pressure, the roller body needs to be replaced frequently, which leads to a significant increase in cost.

[0042] like Figure 1-6 As shown, this utility model embodiment provides a roller assembly for transporting materials, which mainly consists of a shaft 1 and a roller body 2 mounted on the shaft 1 for carrying materials 6.

[0043] Specifically, such as Figure 1-2 As shown, the roller body 2 mainly consists of a constricted section 21 with a platform-like structure at the front end and a straight section 22 with a column-like structure at the rear end. The constricted section 21 and the straight section 22 are integrally formed. A roller rubber sheet 5 with a shape adapted to the roller body 2 is fitted on the outer wall surface of the roller body 2. The roller body 2 contacts the material 6 to be transported through the roller rubber sheet 5. Under the action of the shaft 1, the roller body 2 causes the displacement of the material 6 to change.

[0044] like Figure 3 As shown, the shaft 1 is mainly composed of the shaft body 11 and the stop block 12.

[0045] One end of the shaft body 11 passes through the straight section 22 of the roller body 2 and is fixedly connected to the roller body 2, while the other end is fixedly connected to the drive mechanism (not shown in the figure). A stop block 12 is fixedly disposed radially on one end of the shaft body 11 near the straight section 22, and is tightly fitted to the free-extending end face of the straight section 22. The outer wall surface of the stop block 12 is covered with a high-hardness wear-resistant coating (not shown in the figure). The mutual cooperation between the stop block 12 and the straight section 22 creates a clamping force on the roller rubber 5 fitted onto the outer wall surface of the roller body 2. In this embodiment, the stop block 12 can be a cuboid, a cube, or a cylinder. Preferably, the stop block 12 is cylindrical.

[0046] More specifically, the shaft body 11 is composed of a first shaft body 111, a second shaft body 112, and a third shaft body 113. The outer diameters of the first shaft body 111, second shaft body 112, and third shaft body 113 increase sequentially. One end of the first shaft body 111 is fixedly connected to the drive mechanism, and the other end is integrally connected to the second shaft body 112. The other end of the second shaft body 112 is also integrally connected to the third shaft body 113.

[0047] Furthermore, the roller assembly also includes a gear 3 disposed on the first shaft body 111, which serves as a connecting component for connecting other power devices.

[0048] Furthermore, the roller assembly also includes a bearing housing 4, which is rotatably connected to the second shaft body 112, and the bearing housing 4 is configured to support the shaft 1.

[0049] Furthermore, in order to enable the roller assembly to transport the material 6 smoothly, there are multiple roller assemblies in this embodiment, which are arranged opposite to each other.

[0050] When using, such as Figure 6 As shown, firstly, the roller assembly is fixed in a certain position by the bearing seat 4 according to the application scenario. Then, the material to be transported 6 is placed on the roller assembly, so that the material to be transported 6 comes into contact with the constriction part 21 of the roller body 2. Then, the drive mechanism is started, and the shaft body 11 rotates under the drive of the drive mechanism. At the same time, the roller body 2 and the stop block 12 fixed on the shaft body 11 rotate synchronously. During the rotation of the roller body 2, the material to be transported 6 is transported. At the same time, the rotating stop block 12 and the straight section 22 cooperate with each other to form a clamping force on the roller rubber 5 sleeved on the outer wall of the roller body 2, preventing the roller rubber 5 from deforming and delaminating under the pressure of the material 6. Then, it moves away from the roller body 2 along the shaft body 11, that is, along the direction of the bearing seat 4.

[0051] Furthermore, in this embodiment, the stop block 12 can be integrally formed and disposed on the radial side of the shaft body 11, or it can be detachably fixed on the radial side of the shaft body 11.

[0052] Specifically, when the stop block 12 is detachably fixed in the radial direction of the shaft body 11, its specific structure is as follows: Figure 4-5 As shown, the stop block 12 includes: a first stop block 121 and a second stop block 122 detachably connected to the first stop block 121.

[0053] Connecting heads are provided at both ends where the first stop block 121 and the second stop block 122 connect. Corresponding to the connecting heads of the first stop block 121, connecting grooves are provided at both ends of the second stop block 122. The connecting heads can be inserted into the connecting grooves to achieve a detachable connection between the first stop block 121 and the second stop block 122. A fastening component is provided at the connection between the first stop block 121 and the second stop block 122. The fastening component fixes the first stop block 121 and the second stop block 122 together, thereby allowing the stop block 12 to be adjusted in position according to its application scenario, so that the stop block 12 can better perform its clamping function on the roller rubber 5.

[0054] Furthermore, the connector is a mounting block 1211 with a beveled structure, and a fastening hole 12111 is formed through the mounting block 12111. The connecting groove is a retaining groove 1221 with a beveled structure, and its size is adapted to the mounting block 1211. A fastening groove 1222 is formed on the second stop block 122, and the fastening groove 1222 passes through the retaining groove 1221 and is adapted to the fastening hole 12111.

[0055] Furthermore, the aforementioned fastening assembly may be a screw 123, with internal threads formed in the fastening hole 12111 and the fastening groove 1222, and the fastening assembly is threadedly connected to the fastening groove 1222 and the fastening hole 12111. In addition, the fastening assembly may also be other existing detachable connection devices.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
