Description

Technical Field

[0001] This utility model relates to the field of conveyor roller technology, specifically a dustproof and waterproof conveyor roller. Background Technology

[0002] Conveyor idlers are crucial components of belt conveyors, typically consisting of rollers, bearings, and shafts. Their primary function is to support the conveyor belt and the material on it, ensuring smooth operation. Idler rollers are evenly distributed along the length of the conveyor, reducing friction during belt operation and lowering energy consumption through rotation. They also maintain the belt's proper shape and position, preventing deviation. Different types of conveyor idlers, such as trough idlers, parallel idlers, and self-aligning idlers, are suitable for various working conditions and conveying requirements, improving the overall performance and operating efficiency of the conveyor.

[0003] According to the announcement number CN222351167U, a waterproof and dustproof bearing suitable for conveyor idlers includes an inner ring, an outer ring, two cages, a number of balls, and a number of rivets. The number of balls are located between the two cages in sequence. The two cages and the number of balls are fixed by the number of rivets. The rolling structure composed of the two cages and the number of balls is located between the inner ring and the outer ring.

[0004] This waterproof and dustproof bearing, applicable to conveyor rollers, utilizes a rolling structure positioned between the first and second sealing structures for protection. This solves the problem of moisture, dust, debris, and silt easily entering the bearing during the use of existing conveyor roller bearings. However, its internal sealing effect is not strong, and a small amount of dust can still enter. Therefore, the solution needs to be improved accordingly. Utility Model Content

[0029] The protective mechanism 2 includes a support ring 21, which is fixedly connected to the left and right sides of the roller body 1. A bottom ring 27 is provided on the side of the support ring 21. A telescopic ring 22 is fixedly connected to the left end of the bottom ring 27. A cover ring 23 is fixedly connected to the side of the telescopic ring 22. A locking rod 24 is fixedly connected to the four ends of the cover ring 23. A first spring 25 is fixedly connected to the four ends of the surface of the cover ring 23. A circular ring 26 is fixedly connected to the right end of the first spring 25. A ring groove is opened on the side of the support ring 21, and the surface of the bottom ring 27 fits tightly with the inside of the ring groove.

[0030] Furthermore, a circular hole is opened inside the bottom ring 27, and the surface of the locking rod 24 is slidably connected to the inside of the circular hole. The locking seat 31 drives the cover ring 23 to move and pass through both ends of the roller body 1, thereby driving the bottom ring 27 to be locked into the support ring 21 by the elastic action of the locking rod 24 under the first spring 25 and to fit tightly in place, so as to provide dustproof and waterproof protection for the roller body 1.

[0031] Example 2

[0032] See Figure 1-5 Furthermore, based on Embodiment 1, the positioning mechanism 3 further includes a positioning base 31, which is fixedly connected to the left side of the cover ring 23. A second spring 32 is fixedly connected inside the positioning base 31. A T-shaped block 33 is fixedly connected to one end of the second spring 32. An insertion rod 34 is fixedly connected to one end of the T-shaped block 33. An L-shaped plate 35 is fixedly connected to one end of the insertion rod 34. A T-shaped plate 36 is fixedly connected to the right side of the T-shaped block 33. A locking block 37 is fixedly connected to the surface of the T-shaped plate 36.
