Description

Technical Field

[0001] The utility model relates to the technical field of roller manufacturing, in particular to an anti-locking roller. Background Art

[0002] Rollers are important components of belt conveyors and are available in many types and quantities. Their function is to support the belt, reduce the belt's running resistance, and keep the belt's verticality within a certain limit to ensure smooth belt operation. However, due to the complex workshop environment and fast production pace, the idlers currently on the market may become stuck due to material fatigue, failure to replace bearings in a timely manner, or long-term lack of lubrication of the bearings, or even due to workshop environmental pollution, making the rollers unable to rotate. This will cause huge friction between the rollers and the conveyor belt or work rollers, causing vibration (shake), accelerating the wear of the work rollers or conveyor belt, and directly affecting the power consumption and service life of the conveyor or drive device.

[0003] The patent, with publication number "CN204197901U," is titled "Anti-lock Roller." The device described in this document addresses the aforementioned issues, but a drawback is that while a cover is used to isolate the bearing from external dust, this seal only blocks dust, not liquids. This results in a poor sealing effect and can easily cause lubricant within the bearing to leak from the cover area, leading to severe bearing wear and ultimately roller locking. Based on this, the present invention designs an anti-lock roller to address the aforementioned issues. Utility Model Content

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the device includes a roller shaft 1 and a support shaft 2, the support shaft 2 is arranged inside the roller shaft 1, and a placement hole 3 is integrally provided on the left and right sides of the roller shaft 1, a detachable bearing 4 is tightly provided inside the placement hole 3, and the bearing 4 is sleeved on the outside of the support shaft 2, a sealing assembly 5 is provided inside the placement hole 3, the sealing assembly 5 includes a retaining ring 501 tightly provided inside the placement hole 3, and the retaining ring 501 is sleeved on the outside of the support shaft 2, a first installation groove 502 is integrally provided on the right side of the retaining ring 501, a first sealing ring 503 is fixed inside the first installation groove 502, a second installation groove 504 is integrally provided inside the retaining ring 501, a second sealing ring 505 is fixed inside the second installation groove 504, a card slot 506 is integrally provided on the left and right sides of the support shaft 2, guide grooves 507 are integrally provided at the four corners of the roller shaft 1, and guide blocks 508 are fixed at both ends of the upper end of the outer wall of the retaining ring 501.

[0031] The first mounting groove 502, the second mounting groove 504 and the clamping groove 506 are all designed in a circular direction. A slide groove 6 is integrally provided on the left side of the retaining ring 501. The slide groove 6 is designed in a circular direction. The cross section of the slide groove 6 is a T-shaped design. Slide pins 7 are slidably connected at both ends of the upper end of the slide groove 6, and a blocking ring 8 is fixed on the end of the slide pin 7 away from the slide groove 6. The cross section of the slide pin 7 is a T-shaped design when viewed from the side. The blocking ring 8 is sleeved on the outside of the support shaft 2, and the external fixed sleeve of the blocking ring 8 is provided with a connecting sleeve 9, which is threadedly sleeved on the outside of the roller shaft 1.

[0032] The staff first holds the connecting sleeve 9 and inserts the guide block 508 into the guide groove 507 to keep the retaining ring 501 and the roller shaft 1 in the same concentric state, and then rotates the connecting sleeve 9 to make the connecting sleeve 9 and the roller shaft 1 threadedly connected. At this time, the connecting sleeve 9 in threaded connection with the roller shaft 1 drives the sealing ring 8 to push the sliding pin 7 to drive the slide groove 6 together with the retaining ring 501 and the guide block 508 to move along the inner side of the guide groove 507 until the guide block 508 and the inner side surface of the guide groove 507 fit each other, and the second sealing ring 505 is snapped into the inside of the card groove 506. At this time, the second sealing ring 505 seals the area where the inner wall of the bearing 4 and the support shaft 2 contact each other, and the first sealing ring 503 seals the area where the outer wall of the bearing 4 and the roller shaft 1 contact each other, thereby improving the sealing effect of the bearing 4, that is, increasing the service life of the bearing 4 and reducing the probability of the roller shaft 1 locking.

[0033] Example 2

[0034] like Figure 2 、 Figure 3 、 Figure 4 As shown, the roller shaft 1 is provided with a fixed sleeve with a limit ring 10 on the left and right sides of the outer side. The center of the limit ring 10 is concentric with the center of the roller shaft 1. The roller shaft 1 has drainage holes 11 on the left and right sides of the top. The drainage holes 11 are through-holes. The axis of the drainage holes 11 is perpendicular to the axis of the roller shaft 1. The limit ring 10 is provided with a clearance hole 12 on the inner side. The clearance hole 12 is a through-hole. The clearance hole 12 and the drainage hole 11 are in a mutually overlapping state. The positioning hole 12 is designed in an L-shaped direction, and the drainage hole 11 is arranged between the bearing 4 and the retaining ring 501. The distance between the bearing 4 and the retaining ring 501 is one centimeter. The upper end of the connecting sleeve 9 is integrally provided with a liquid inlet hole 13. The liquid inlet hole 13 is a through hole design. A one-way valve 14 is fixed inside the liquid inlet hole 13. The axis of the liquid inlet hole 13 is parallel to the axis of the roller shaft 1, and the interior of the liquid inlet hole 13 and the interior of the positioning hole 12 are connected.

[0035] According to the operation method in Example 1, when the guide block 508 and the inner side surface of the guide groove 507 are in contact with each other, the connecting sleeve 9 and the limiting ring 10 are in a tightly contacted state. At the same time, the liquid inlet hole 13 and the clearance hole 12 overlap with each other. When the lubricating fluid in the bearing 4 is depleted due to long-term use, the staff can inject new lubricating oil into the position between the retaining ring 501 and the bearing 4 through the clearance hole 12 and the drainage hole 11, further improving the service life of the bearing 4. The one-way valve 14 prevents the lubricating fluid in the bearing 4 from being discharged to the outside through the liquid inlet hole 13.
