Furthermore, the guide groove on the circumference of the guide groove reinforced section of the roller prevents deviation between the conveyor belt and the drive roller, ensuring smooth operation of the conveyor belt and enhancing the stability of the mushroom basket transport.

[0004] Based on the above-mentioned existing technology, the existing conveying rollers still have the following problems: when traditional conveying rollers are running at high speed or conveying heavy materials, they are prone to violent vibration. This not only leads to increased wear on the rollers themselves and related connecting parts, shortening their service life, but also makes it easy for the conveyed materials to shift or fall, affecting production and transportation efficiency. Therefore, this utility model provides a shockproof and stable conveying roller. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a shock-resistant and stable conveyor roller, which solves the problem that traditional conveyor rollers are prone to severe vibration when operating at high speeds or conveying heavy materials. This not only leads to increased wear on the roller itself and related connecting parts, shortening its service life, but also makes it easy for the conveyed materials to shift or fall, affecting production and transportation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant and stable conveying roller, comprising a base plate, with multiple conveying components equidistantly arranged on the top of the base plate, each conveying component having a buffer component inside and a transmission component on the outside of each conveying component; each conveying component includes a first U-shaped frame installed on the top surface of the base plate, with a roller shaft inside the first U-shaped frame, and a roller fixedly sleeved on the outer wall of the roller shaft near the middle position; the buffer component includes two second U-shaped frames symmetrically arranged below the roller, with a support shaft rotatably arranged between the inner walls of the left and right sides of the second U-shaped frame, and the support shaft being parallel to the roller, with a rubber sleeve sleeved on the outer wall of the support shaft, the rubber sleeve fitting against the roller; multiple second limiting telescopic rods and second springs are arranged and installed on the bottom surface of the second U-shaped frame, the second springs being sleeved outside the second limiting telescopic rods, and the bottom ends of the second limiting telescopic rods and the second springs being fixedly connected to the inner bottom surface of the first U-shaped frame.

[0012] Beneficial effects

[0013] This invention provides a shock-resistant and stable conveyor roller. Compared with the prior art, it has the following advantages:

[0014] 1. This shockproof and stable conveyor roller can absorb some of the vibration energy when the roller vibrates due to high-speed operation or conveying heavy materials, thus playing a preliminary buffering role. If the vibration is more severe, the roller presses down on the rubber sleeve, which will drive the second U-shaped frame to move downward. At this time, the second limit telescopic rod retracts and the second spring is compressed. The elastic deformation of the second spring can further absorb and disperse the vibration energy, effectively reducing the impact of vibration on the roller and related connecting parts, reducing the wear of parts, and extending service life.

[0015] 2. This shockproof and stable conveyor roller has a roller shaft that can move up and down within the straight groove. When the roller vibrates, the shaft seat at the left end of the roller shaft will press the first limit telescopic rod and the first spring to further buffer the vibration and ensure that the roller shaft can still rotate normally when vibrating. In addition, the spline shaft can slide within the bushing, and the third spring can adapt to the up and down movement of the roller shaft, ensuring that the second bevel gear and the first bevel gear always maintain a good meshing state and ensuring stable power transmission.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides two technical solutions:

[0023] A shock-resistant and stable conveyor roller includes a base plate 1. Multiple conveying components 2 are equidistantly arranged on the top of the base plate 1. Each conveying component 2 has a buffer component 3 inside and a transmission component 4 on its outer side. Each conveying component 2 includes a first U-shaped frame 21 mounted on the top surface of the base plate 1. A roller shaft 23 is located inside the first U-shaped frame 21, and a roller 24 is fixedly sleeved on the outer wall of the roller shaft 23 near its center. The buffer component 3 includes two second U-shaped frames 31 symmetrically arranged below the roller 24. A support shaft 32 is rotatably arranged between the inner walls of the left and right sides of the second U-shaped frame 31, and the support shaft 32 is parallel to the roller 24. A rubber sleeve 33 is sleeved on the outer wall of the support shaft 32, and the rubber sleeve 33 fits against the roller 24. Multiple second limiting telescopic rods 34 and second springs 35 are arranged and installed on the bottom surface of the second U-shaped frame 31. The second springs 35 are sleeved outside the second limiting telescopic rods 34, and the bottom ends of both the second limiting telescopic rods 34 and the second springs 35 are fixedly connected to the inner bottom surface of the first U-shaped frame 21. Straight slots 22 are provided through the outer walls on both the left and right sides of the first U-shaped frame 21. The straight slots 22 are set along the height direction of the first U-shaped frame 21. The roller shaft 23 is movably set inside the two straight slots 22. The first bevel gear 25 is fixedly installed on the right end of the roller shaft 23.

[0024] Specifically, the power is transmitted to the first bevel gear 25 at the right end of the roller shaft 23 through the transmission component 4. The first bevel gear 25 drives the roller shaft 23 to rotate, so that the roller 24 rotates synchronously, thereby realizing the conveying of materials on the roller 24.

[0025] Furthermore, when the roller 24 vibrates due to high-speed operation or conveying heavy materials, the rubber sleeve 33 can absorb some of the vibration energy due to its own elasticity, playing a preliminary buffering role. If the vibration is more severe, the roller 24 presses down on the rubber sleeve 33, which will drive the second U-shaped frame 31 to move downward. At this time, the second limit telescopic rod 34 retracts, and the second spring 35 is compressed. The elastic deformation of the second spring 35 can further absorb and disperse the vibration energy, effectively reducing the impact of vibration on the roller 24 and related connecting parts, reducing the wear of parts, and extending service life.

[0026] Furthermore, the roller 23 is movably disposed within the straight groove 22, which allows the roller 23 to move up and down within a certain range. When conveying materials of different weights or shapes, the roller 23 can adaptively adjust its position to ensure smooth conveying.

[0027] In this embodiment, the transmission assembly 4 includes a fixed plate 41 fixedly mounted on the right surface of the first U-shaped frame 21. A bushing 42 is rotatably mounted on and passes through the fixed plate 41. The bushing 42 is vertically arranged, and a splined shaft 43 is slidably mounted inside the bushing 42. A second bevel gear 44 is fixedly mounted on the top end of the splined shaft 43, and the second bevel gear 44 meshes with the first bevel gear 25. A fixed block 45 is fixedly sleeved on the outer wall of the bushing 42 above the fixed plate 41. A third spring 46 is fixedly mounted on the top of the fixed block 45, and the top end of the third spring 46 is fixedly connected to the bottom end of the second bevel gear 44.

[0028] Specifically, when external power input causes the bushing 42 to rotate, it drives the spline shaft 43 to rotate synchronously. The second bevel gear 44 at the top of the spline shaft 43 meshes with the first bevel gear 25 at the right end of the roller shaft 23, thereby transmitting power to the roller shaft 23 and driving the roller 24 to rotate to achieve material conveying.

[0029] Furthermore, when the roller 23 moves up and down within the straight groove 22, it will drive the first bevel gear 25 to move up and down. At this time, the spline shaft 43 can slide within the bushing 42, and the third spring 46 will extend and retract according to the position change of the first bevel gear 25. The third spring 46 can ensure that the second bevel gear 44 and the first bevel gear 25 always maintain a good meshing state, and can also buffer the impact force that may be generated during the power transmission process.

[0030] In this embodiment, a support plate 26 is fixedly installed on the left surface of the first U-shaped frame 21. A first limiting telescopic rod 27 and a first spring 29 are fixedly connected to the top surface of the support plate 26. The first spring 29 is sleeved outside the first limiting telescopic rod 27. A shaft seat 28 is fixedly connected between the top ends of the first limiting telescopic rod 27 and the first spring 29. The shaft seat 28 is rotatably connected to the left end of the roller shaft 23.

[0031] Specifically, this part of the structure mainly serves to support, buffer, and stabilize the roller shaft 23. When the roller 24 vibrates due to high-speed operation or carrying heavy materials, the roller shaft 23 will move up and down within the straight groove 22, and the shaft seat 28 will move accordingly, compressing or stretching the first spring 29. The first limiting telescopic rod 27 plays a limiting and guiding role in the extension and retraction of the first spring 29, ensuring that it extends and retracts in a straight line.

[0032] In this embodiment, a sprocket and chain assembly 5 is provided between multiple bushings 42 at a position below the fixing plate 41, and a drive shaft 6 is fixedly connected to the bottom end of one of the bushings 42.

[0033] Specifically, when power is input to the drive shaft 6, the drive shaft 6 drives the bushing 42 fixedly connected to it to rotate. Since the sprocket and chain assembly 5 connects multiple bushings 42 together, the rotation of the bushing 42 is transmitted to other bushings 42 through the sprocket and chain assembly 5, so that all bushings 42 rotate synchronously.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: Upon startup, power is transmitted to the drive shaft 6, which drives the connected bushing 42 to rotate. Multiple bushings 42 rotate synchronously via the sprocket and chain assembly 5. The splined shaft 43 inside the bushing 42 rotates accordingly. The second bevel gear 44 at the top of the splined shaft 43 meshes with the first bevel gear 25 at the right end of the roller shaft 23, driving the roller shaft 23 to rotate, which in turn causes the roller 24 to rotate to convey materials.

[0036] When the roller 24 rotates at high speed or vibrates while conveying heavy materials, the buffer component 3 comes into play. The rubber sleeve 33 below the roller 24 fits against the roller 24, which can initially buffer the vibration. If the vibration intensifies, the roller 24 presses down on the rubber sleeve 33, which drives the support shaft 32 and the second U-shaped frame 31 to move downward. At this time, the second limit telescopic rod 34 retracts and the second spring 35 is compressed, absorbing and dispersing the vibration energy and reducing the impact on the roller 24 and related connecting parts.

[0037] Meanwhile, the roller 23 can move up and down within the straight groove 22. When the roller 24 vibrates, the shaft seat 28 at the left end of the roller 23 will squeeze the first limiting telescopic rod 27 and the first spring 29 to further buffer the vibration and ensure that the roller 23 can still rotate normally when vibrating. In addition, the spline shaft 43 can slide within the bushing 42, and the third spring 46 can adapt to the up and down movement of the roller 23, ensuring that the second bevel gear 44 and the first bevel gear 25 always maintain a good meshing state and ensure stable power transmission.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
