Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a roller with a double-sealed structure. Background Technology

[0002] Idler rollers are key load-bearing components of belt conveyors, primarily used to support the conveyor belt and the weight of materials, reducing running resistance. Their quality directly affects the conveyor's energy consumption and belt life, and they are widely used in the logistics and transportation industries. However, in actual use, the sealing components on both sides of the idler roller are directly exposed. When used in harsh environments, the outer sealing components are corroded by the environment, leading to accelerated aging and damage, resulting in decreased sealing performance and requiring frequent maintenance and replacement. This is a drawback, as there is no measure to provide double sealing for the idler roller. Now, a novel idler roller with a double-sealed structure is proposed to address the above-mentioned shortcomings. Utility Model Content

A mounting hole 16 is opened on the outside of the bearing seat 2. An inner hole 18 is opened inside the outer cover 3, and several bristles 19 are fixed inside the inner hole 18. The bearing housing 2, outer cover 3, shaft 4, retaining ring 5, outer sealing ring 6, inner sealing ring 7 and bearing body 9 are symmetrically arranged about the vertical center line of the roller body 1. The two sides of the shaft 4 pass through the interior of the bearing body 9, inner sealing ring 7, outer sealing ring 6, outer cover 3 and bearing housing 2 respectively. Four sets of mounting bolts 17 are distributed in a ring at equal intervals on the outer side of the outer cover 3. Four sets of mounting holes 16 are distributed in a ring at equal intervals on the outer side of the bearing housing 2. The mounting bolts 17 pass through the interior of the outer cover 3 and are threaded into the mounting holes 16. Several bristles 19 are distributed in a ring on the inner side of the inner hole 18. Specifically, such as Figure 1 and Figure 2 As shown, the roller body 1, bearing housing 2, outer cover 3, shaft 4, retaining ring 5, outer sealing ring 6, inner sealing ring 7, mounting hole 2 16, mounting bolt 2 17, inner hole 18, and brush bristles 19 are all present. When the idler roller is installed and used, the outer sealing ring 6 and inner sealing ring 7 installed in the bearing housing 2 on both sides of the roller body 1 can prevent dust, moisture, and other impurities from entering the interior of the bearing body 9, ensuring its lubrication and long-term operational stability. At the same time, the outer cover 3 is installed and fixed on the outside of the bearing housing 2 on both sides of the roller body 1. The outer cover 3 can be used to provide auxiliary outer sealing and dust and water protection for the inner outer sealing ring 6 and inner sealing ring 7. During the rotation of the roller body 1, the outer cover 3 can be rotated synchronously. The brush bristles 19 can fill the gap between the shaft body 4 and the outer cover 3 to block dust. The double sealing structure further improves the internal sealing performance of the idler roller.

[0017] Limiting rings 8 are provided on both sides of the outer side of the roller body 1, and four sets of threaded holes 21 are provided on the outer side of the limiting rings 8. The threaded holes 21 are connected to the threads of fixing bolts 20. The four sets of threaded holes 21 are distributed in a ring at equal intervals on the outer side of the limiting rings 8. The threaded holes 21 penetrate the interior of the limiting rings 8, and the fixing bolts 20 penetrate the interior of the threaded holes 21. Specifically, such as Figure 1 and Figure 3 As shown, limit rings 8 are provided on both sides of the outside of the roller body 1. The two sets of symmetrically fixed limit rings 8 can assist in guiding and limiting the conveyor belt at the center position outside the roller body 1, so that the outer conveyor belt can be kept in the center position of the idler roller. By loosening the fixing bolt 20 from the threaded hole 21, the limit rings 8 can be unlocked outside the roller body 1. Then, the two sets of limit rings 8 on both sides can be moved left and right to adjust the limiting distance between the two sets of limit rings 8.

[0018] The roller body 1 has an installation groove 10 on its outer side, and a plate 11 is provided inside the top of the installation groove 10. A plate 2 15 is provided inside the bottom of the installation groove 10. Two sets of countersunk holes 12 are provided on the top and both ends of the plate 11 and the bottom and both ends of the plate 2 15. An installation bolt 13 is provided inside the countersunk holes 12. An installation hole 14 is provided on the top, bottom and both ends of the roller body 1 to cooperate with the installation bolt 13. The plate 11 and the plate 2 15 are symmetrically arranged about the horizontal center line of the installation groove 10. The countersunk holes 12 penetrate the interior of the plate 11 and the plate 2 15 respectively. The installation bolt 13 penetrates the interior of the countersunk holes 12 and is threaded into the installation hole 14. Specifically, such as Figure 1 and Figure 4 As shown, by installing plate 11 and plate 2 15 on the outer side of roller 1, the plate 11 and plate 2 15 can be used to provide auxiliary padding and anti-wear protection for the contact position of the center position of the idler roller. At the same time, the separate and detachable parts make maintenance and replacement convenient.

[0019] Working Principle: During installation and use, the outer sealing ring 6 and inner sealing ring 7 are installed in the bearing seats 2 on both sides of the roller body 1 to prevent dust, moisture, and other impurities from entering the interior of the bearing body 9, ensuring its lubrication and long-term operational stability. Simultaneously, outer covers 3 are fixedly installed on the outside of the bearing seats 2 on both sides of the roller body 1. These outer covers 3 provide auxiliary sealing for the inner outer sealing ring 6 and inner sealing ring 7, preventing dust and water damage. During the rotation of the roller body 1, the outer covers 3 rotate synchronously. Several bristles 19 fill the gap between the shaft body 4 and the outer covers 3 to prevent dust accumulation, creating a double-seal structure. Additionally, limit rings 8 are set on both sides of the outside of the roller body 1. The two sets of symmetrically fixed limit rings 8 provide auxiliary guidance and limit for the conveyor belt at the center position on the outside of the roller body 1, ensuring that the outer conveyor belt moves in the center position. Furthermore, when the idler is in use, plates 11 and 25 are installed on the outer side of the roller body 1. Plates 11 and 25 can be used to provide auxiliary padding and anti-wear protection for the contact position of the conveyor belt at the center of the idler.
