Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a dustproof roller structure. Background Technology

[0002] In the field of mechanical manufacturing, rollers are frequently used in transmission connections, such as in conveyor belts and conveyors. Currently, the commonly used roller assembly involves machining the shaft in the middle of the roller and then fitting it with a bearing to complete the roller assembly, which is relatively complex. In the lithium battery production process, rollers are used to support the transmission and transport of electrode sheets. Therefore, dust generated during electrode transmission friction often enters the inside of the roller, causing damage to the roller's bearings. This necessitates frequent production shutdowns for roller repair, resulting in economic losses. Utility Model Content

[0003] The main objective of this invention is to provide a dustproof roller structure to solve the above-mentioned technical problems and prevent dust from entering the roller.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dustproof roller structure includes an end cover, a roller shaft, and a roller structure. One end of the roller shaft is mounted on a frame, and the roller structure is rotatably mounted on the roller shaft. The end cover is mounted on the other end of the roller shaft. The roller structure includes a roller, a bearing housing, a fixing sleeve, a dustproof baffle, and a bearing. The bearing housing is mounted on the inner surface of the roller and located at both ends of the roller. The bearing is sleeved on the roller shaft and abuts against the bearing housing. The fixing sleeve is sleeved on the roller shaft and abuts against the side of the bearing. The dustproof baffle is fixed on the fixing sleeve and the roller shaft, and the dustproof baffle is close to both ends of the roller.

[0006] As a preferred technical solution, a first gap is provided between the fixing sleeve and the bearing seat.

[0007] As a preferred technical solution, the width of the first gap is 0.2-0.5mm.

[0008] As a preferred technical solution, a second gap is provided between the bearing housing and the roller shaft.

[0009] As a preferred technical solution, the width of the second gap is 0.2-0.5mm.

[0010] As a preferred technical solution, the roller shaft is provided with dustproof grooves, which are equidistantly arranged on the roller shaft and are located in the second gap.

[0011] The beneficial effects of this utility model are as follows: The above-mentioned dustproof roller structure adopts two methods for dust prevention. By setting dustproof plates at both ends of the roller, dust is prevented from entering the bearing. There are gaps between the fixed sleeve and the bearing seat, and between the bearing seat and the roller shaft. When the roller rotates, the bearing seat rotates and generates airflow, thereby preventing dust from entering the gap, thus achieving dust blocking and improving the service life of the roller.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figure 1 and Figure 2As shown, a dustproof roller structure includes an end cover 3, a roller shaft 2, and a roller structure 1. One end of the roller shaft 2 is mounted on the frame, and the roller structure 1 is rotatably mounted on the roller shaft 2. The end cover 3 is mounted on the other end of the roller shaft 2. The roller structure 1 includes a roller 21, a first bearing seat 22, a second bearing seat 23, a fixing sleeve 28, a first dustproof baffle 26, a second dustproof baffle 27, a first bearing 24, and a second bearing 25. The first bearing seat 22 and the second bearing seat 23 are mounted on the inner surface of the roller 21 and are located at both ends of the roller 21. The first bearing 24 and the second bearing 25 are sleeved on the roller shaft 2, and the first bearing 24 abuts against the first bearing seat 22. 25 abuts against the second bearing seat 23, thereby allowing the roller 21 to rotate relative to the roller shaft 2 through the first bearing 24 and the first bearing seat 22. The fixing sleeve 28 is sleeved on the roller shaft 1 and abuts against the side of the first bearing 22, thereby preventing the roller 21 from shifting during transmission. The first dust baffle 26 is fixed on the fixing sleeve 28, and the second dust baffle 27 is fixed on the roller shaft 1. The first dust baffle 26 and the second dust baffle 27 are close to the two ends of the roller 21, thereby preventing dust from passing through the first dust baffle 26 and the second dust baffle 27 and entering the first bearing 24 and the second bearing 25, affecting the movement of the first bearing 24 and the second bearing 25.

[0018] like Figure 3 As shown, a first gap 221 is provided between the fixed sleeve 28 and the first bearing seat 22. The width of the first gap 221 is 0.2-0.5mm. The rotation of the roller 21 drives the first bearing seat 22 to rotate, thereby generating negative pressure and airflow, thus preventing dust from entering the first gap 221.

[0019] like Figure 4 As shown, a second gap 231 is provided between the second bearing housing 23 and the roller shaft 1. The width of the second gap 231 is 0.2-0.5mm. The rotation of the roller 21 drives the second bearing housing 23 to rotate, thereby generating negative pressure and airflow, thus preventing dust from entering the second gap 231. In particular, a dustproof groove 11 is provided on the roller shaft 1. The dustproof grooves 11 are equidistantly arranged on the roller shaft 1 and are located in the second gap 231. When dust enters the second gap 231, it can fall into the dustproof groove 11, thereby preventing dust from entering the second bearing 25.

[0020] The embodiments described above are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of this utility model patent application.
