A sealing end cover is provided on the outside of the bearing. A retaining ring is provided on the outside of the sealing end cover.

[0004] There are some problems with this type of conveyor belt idler. For example, the inner diameter of the idler shaft is fixed, and it can only be stably installed on U-shaped frames with specific thicknesses and inner diameters, which limits the range of applications for the idler installation. The outer surface of the idler cylinder is smooth, and the conveyor belt is in direct contact with the idler body, which will reduce the friction between the idler and the conveyor belt to a certain extent, and at the same time affect the service life of the idler cylinder.

[0009] Furthermore, the installation mechanism includes an adjusting cylinder, a sliding groove, and an outer support plate. The adjusting cylinder is respectively disposed at the left and right ends of the idler roller shaft. The adjusting cylinder near the center of the idler roller shaft and both ends of the idler roller shaft are provided with evenly distributed sliding grooves. An outer support plate is slidably connected between any two laterally adjacent sliding grooves. Adjusting the inner diameter of the idler roller shaft connection facilitates the use of U-shaped frames with different inner diameters.

[0010] Furthermore, the installation mechanism also includes a rotating shaft, a sliding seat, and connecting rods. The rotating shaft is rotatably connected to the left and right ends of the idler roller shaft, and the middle of the outer surface of the rotating shaft is provided with two external threads with opposite helical directions. The middle of the external threads is threaded with a sliding seat, and the outer arc surface of the sliding seat is rotatably connected with evenly distributed connecting rods. The end of the connecting rod away from the center of the rotating shaft is rotatably connected to the middle of the radially adjacent outer support plate on the side surface near the center of the rotating shaft, providing driving force for the movement of the outer support plate.

[0011] Furthermore, a knob is fixedly connected to the end of the rotating shaft away from the center of the idler roller shaft to facilitate the rotation of the rotating shaft.

[0012] Furthermore, the installation mechanism includes a limiting cylinder and a limiting ring. The limiting ring is fixedly connected to the left and right ends of the outer arc surface of the roller shaft, and the outer arc surface of the adjusting cylinder is provided with external thread II.

[0016] 1. The intersecting arc-shaped support ribs, ring-shaped support rib one, and ring-shaped support rib two with different cross-sectional radii provide stable support for the idler roller. At the same time, as the conveyor belt comes into contact with the outer surface of the idler roller, the arc-shaped support ribs, ring-shaped support rib one, and ring-shaped support rib two with different cross-sectional radii successively come into contact with the conveyor belt, avoiding direct wear of the idler roller body by the conveyor belt. This provides full and lasting protection for the idler roller body and greatly improves the service life of the rubber tire idler roller.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This embodiment provides a technical solution: a rubber and plastic tire idler roller, including an idler roller shaft 1, an idler roller cylinder 2 fixedly connected to the middle of the outer surface of the idler roller shaft 1, both the idler roller shaft 1 and the idler roller cylinder 2 are made of ultra-high graphene fiber, and also includes a support mechanism 3 and an installation mechanism 4;

[0024] Support mechanism 3 includes arc-shaped support ribs 31, annular support rib one 32, and annular support rib two 33. The arc-shaped support ribs 31 are uniformly and fixedly connected to the outer arc surface of the idler roller 2. The annular support rib one 32 and the annular support rib two 33 are uniformly and fixedly connected to the outer arc surface of the idler roller 2. The annular support rib one 32 and the annular support rib two 33 are spaced apart. Both the annular support rib one 32 and the annular support rib two 33 intersect with adjacent arc-shaped support ribs 31. The cross-sectional radius of the arc-shaped support ribs 31 is larger than the cross-sectional radius of the annular support rib one 32. The cross-sectional radius of the second type support rib 33 is larger than that of the arc-shaped support rib 31. During the use of the idler roller, the arc-shaped support rib 31, the ring-shaped support rib 32 and the ring-shaped support rib 33 with different cross-sectional radii intersect each other to achieve stable support of the idler roller. At the same time, as the conveyor belt contacts the outer surface of the idler roller 2, the arc-shaped support rib 31, the ring-shaped support rib 32 and the ring-shaped support rib 33 with different cross-sectional radii contact the conveyor belt in sequence, avoiding direct wear of the idler roller body by the conveyor belt, providing sufficient and long-lasting protection for the idler roller body, and greatly improving the service life of the rubber tire idler roller.

[0025] Mounting mechanism 4: It is respectively set at the left and right ends of the idler shaft 1. Mounting mechanism 4 includes adjusting cylinder 41, slide groove 42 and outer support plate 46. The adjusting cylinder 41 is respectively set at the left and right ends of the idler shaft 1. The end of the adjusting cylinder 41 near the center of the idler shaft 1 and the left and right ends of the idler shaft 1 are provided with evenly distributed slide groove 42. The outer support plate 46 is slidably connected between two horizontally adjacent slide grooves 42. Mounting mechanism 4 also includes rotating shaft 43, sliding seat 44 and connecting rod 45. The rotating shaft 43 is rotatably connected to the left and right ends of the idler shaft 1. The end of the rotating shaft 43 away from the center of the idler shaft 1 is fixedly connected with a knob. The outer surface of the rotating shaft 43 is... The middle of each surface is provided with two external threads of opposite helical direction. A sliding seat 44 is threadedly connected to the middle of each external thread. A uniformly distributed connecting rod 45 is rotatably connected to the outer arc surface of each sliding seat 44. The end of each connecting rod 45 away from the center of the rotating shaft 43 is rotatably connected to the middle of the radially adjacent outer support plate 46 on the side closest to the center of the rotating shaft 43. The installation mechanism 4 includes a limiting cylinder 47 and a limiting ring 48. The limiting ring 48 is fixedly connected to the left and right ends of the outer arc surface of the roller shaft 1. The outer arc surface of the adjusting cylinder 41 is provided with external threads, and the limiting cylinder 47 is threadedly connected to the middle of each external thread. The thickness of the U-shaped frame to be installed is determined according to the required thickness. To determine the diameter and inner diameter, first turn the knob. Turning the knob rotates the corresponding shaft 43. The rotation of shaft 43 causes adjacent sliding seats 44 to move towards each other under the action of their respective external threads. The movement of sliding seats 44 causes the ends of adjacent connecting rods 45 closest to the center of shaft 43 to move towards each other. This, in turn, causes the ends of connecting rods 45 furthest from the center of shaft 43 to push radially adjacent outer support plates 46 outwards. The outer support plates 46 move between two laterally adjacent sliding grooves 42 in a direction away from the center of shaft 43. The three outer support plates 46 on the same side of the roller shaft 1 cooperate to form a cylinder. When the cylinder diameter reaches the required value, the rotation stops. Turn the knob and rotate the limiting cylinder 47. Under the action of the corresponding external thread 2, the limiting cylinder 47 moves towards the center of the idler shaft 1. When the distance between the side surface of the limiting cylinder 47 near the center of the idler shaft 1 and the side surface of the adjacent limiting ring 48 away from the center of the idler shaft 1 reaches the required value, stop rotating the limiting cylinder 47. Then install the idler shaft 1 between the two U-shaped frames. The outer support plates 46 are all located inside the U-shaped frames and provide rotational support for the idler shaft 1. At the same time, the limiting cylinder 47 and the adjacent limiting ring 48 clamp the U-shaped frames, thereby achieving stable installation of the idler shaft 1, the idler cylinder 2, and other mechanisms.

[0026] Among them, the outer arc surface of the adjusting cylinder 41 away from the center of the roller shaft 1 and the adjacent limiting cylinder 47 are both provided with a bellows 5. The external thread 2 is located inside the adjacent bellows 5. The bellows 5 expands and contracts with the movement of the limiting cylinder 47, providing protection for the external thread 2 and avoiding external environmental factors from affecting the thread connection efficiency of the external thread 2 and the limiting cylinder 47. The adjusting cylinder 41 near the center of the roller shaft 1 and the sliding seat 44 away from the center of the roller shaft 1, the two adjacent sliding seats 44 laterally, and the sliding seat 44 near the center of the roller shaft 1 and the roller shaft 1 are all fixedly connected with bellows 2. The bellows 2 are movably sleeved on the outer surface of the adjacent rotating shaft 43. The bellows 2 expands or contracts accordingly according to the movement of the sliding seat 44. The bellows 2 provides protection for the external thread 1 and avoids external environmental factors from affecting the thread connection efficiency of the external thread 1 and the limiting cylinder 47.

[0027] The working principle of the rubber and plastic tire idler roller provided by this utility model is as follows: During operation, the operator first rotates the knob according to the thickness and inner diameter of the U-shaped frame to be installed. The rotation of the knob drives the corresponding rotating shaft 43 to rotate. The rotation of the rotating shaft 43 causes the two adjacent sliding seats 44 to move towards each other under the action of the corresponding external thread one. The movement of the sliding seats 44 causes the ends of the adjacent connecting rods 45 near the center of the rotating shaft 43 to move towards each other. This causes the ends of the connecting rods 45 away from the center of the rotating shaft 43 to push the radially adjacent outer support plates 46 outward. The outer support plates 46 move away from the center of the rotating shaft 43 between the two laterally adjacent sliding grooves 42. The three outer support plates 46 on the same side of the idler roller shaft 1 cooperate with each other to form a cylinder. When the diameter of the cylinder reaches the required value, the operator stops rotating the knob and rotates the limiting cylinder 47. The limiting cylinder 47 moves towards the center of the idler roller shaft 1 under the action of the corresponding external thread two. When the limiting cylinder 47 is close to the center of the idler roller shaft 1... When the distance between one side surface of the idler roller 1 and the adjacent limiting ring 48 on the side surface away from the center of the idler roller 1 reaches the required value, the operator stops rotating the limiting cylinder 47 and then installs the idler roller 1 between the two U-shaped frames. The outer support plates 46 are all located inside the U-shaped frames and provide rotational support for the idler roller 1. At the same time, the limiting cylinder 47 and the adjacent limiting ring 48 clamp the U-shaped frames, thereby achieving stable installation of the idler roller 1, the idler roller 2, and other mechanisms. During the use of the idler roller, the arc-shaped support ribs 31, the first ring support rib 32, and the second ring support rib 33 with different cross-sectional radii intersect to achieve stable support for the idler roller. At the same time, as the conveyor belt contacts the outer surface of the idler roller 2, the arc-shaped support ribs 31, the first ring support rib 32, and the second ring support rib 33 with different cross-sectional radii contact the conveyor belt in sequence, avoiding direct wear of the idler roller body by the conveyor belt, providing sufficient and durable protection for the idler roller body, and greatly improving the service life of the rubber tire idler roller.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
