[0003] During the material conveying process, especially in areas with height differences, materials will generate impact force on the conveyor belt when they fall. The existing roller frames are not equipped with buffers, causing the impact force to be directly transmitted to the conveyor belt, resulting in increased wear of the conveyor belt and rollers, and reducing the service life of the conveyor belt and rollers.

[0006] Preferably, the bidirectional screw is driven to rotate by a knob, and the square nut slides on the surface of the mounting bracket through the rotation of the bidirectional screw. Two groups of square nuts are provided, and the sliding directions of the two groups of square nuts are opposite.

[0007] Preferably, the support plate slides and rises on the surface of the mounting frame through the telescopic end of the telescopic rod, and the square nut drives the support plate to slide and rise through the adjusting rod during the sliding process.

[0008] Preferably, a guide hole is opened on the surface of the guide frame, and the slider is in a "cross" shape, and the slider slides on the guide hole of the guide frame.

[0009] Preferably, the telescopic damper is sleeved on the first buffer spring, and the first buffer spring and the telescopic damper are located on the guide hole of the guide frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The roller frame, when the impact force of the material acts on the roller through the conveyor belt, the roller simultaneously drives the slider, the connecting plate and the mounting block to slide downward on the guide frame, and the telescopic damper and the second buffer spring reduce the displacement of the impact slider and the mounting block on the guide frame, and the first buffer spring can quickly reduce the vibration generated by the slider, thereby reducing the vibration of the connecting plate and the mounting block. On the guide frame, the first buffer spring, the telescopic damper and the mounting block quickly reduce the sliding impact of the slider, the connecting plate and the mounting block on the guide frame, thereby reducing the impact force of the material on the roller, thereby reducing the direct impact of the material on the conveyor belt and the roller, thereby extending the service life of the conveyor belt and the roller, and reducing the frequency of maintenance and replacement.

[0014] 2. The roller frame drives the bidirectional screw to rotate through the knob, and the bidirectional screw drives the square nut to slide through rotation. The square nut drives one end of the adjusting rod to move when it slides. Since the support plate slides on the mounting frame through the telescopic rod, the square nut drives the support plate to rise and fall through the adjusting rod during the sliding process. The support plate then drives the roller to rise and fall through the guide frame, completing the adjustment of the horizontal height of the roller, thereby changing the horizontal height of the conveyor belt, reducing the height difference of the material falling, and thus reducing the wear of the material on the conveyor belt and roller.

[0024] Furthermore, the bidirectional screw rod 11 is driven to rotate by the knob 12, and the square nut 14 slides on the surface of the mounting frame 1 through the rotation of the bidirectional screw rod 11. Two groups of square nuts 14 are provided, and the sliding directions of the two groups of square nuts 14 are opposite. The square nut 14 drives one end of the adjusting rod 15 to move, and the adjusting rod 15 rotates during the movement.

[0025] Furthermore, the support plate 16 slides and rises on the surface of the mounting frame 1 through the telescopic end of the telescopic rod 13. During the sliding process, the square nut 14 drives the support plate 16 to slide and rise through the adjusting rod 15. Two groups of telescopic rods 13 are provided. The two groups of telescopic rods 13 ensure the stability of the support plate 16 when rising and falling on the mounting frame 1.

[0026] Furthermore, a guide hole is opened on the surface of the guide frame 2, and the slider 21 is in a "cross" shape. The slider 21 slides on the guide hole of the guide frame 2, and the guide hole of the guide frame 2 is also in a "cross" shape, ensuring the horizontal sliding and lifting of the guide frame 2.

[0027] Furthermore, the telescopic damper 23 is sleeved on the first buffer spring 22. The first buffer spring 22 and the telescopic damper 23 are located on the guide hole of the guide frame 2. The first buffer spring 22 and the telescopic damper 23 cooperate with each other to reduce the impact force and vibration, thereby ensuring the stability of the roller 3.

[0028] Furthermore, the connecting plate 24 and the mounting block 25 slide and rise and fall on the surface of the guide frame 2 through the slider 21, and the mounting block 25 drives the roller 3 to slide and rise and fall on the surface of the guide frame 2. The roller 3 removes the impact force by sliding downward on the guide frame 2. While the roller 3 slides downward, it drives the slider 21, the connecting plate 24 and the mounting block 25 to slide downward, and the first buffer spring 22 and the telescopic damper 23 buffer the impact force of the guide frame 2.

[0029] Furthermore, the elastic force of the telescopic damper 23 acts on the slider 21, and the end of the second buffer spring 26 away from the mounting block 25 is fixedly connected to the top of the guide frame 2. The elastic force of the second buffer spring 26 acts on the mounting block 25, and the second buffer spring 26 also reduces the impact force of the mounting block 25 when it descends on the guide frame 2, thereby reducing the wear of the roller 3 and the conveyor belt caused by the falling material.

[0030] Working principle: When the material falls onto the conveyor belt, the impact force will act on the roller 3 through the conveyor belt, and the roller 3 will drive the slider 21, the connecting plate 24 and the mounting block 25 to slide downward on the guide frame 2 at the same time. The telescopic damper 23 and the second buffer spring 26 reduce the displacement of the impact slider 21 and the mounting block 25 on the guide frame 2, and the first buffer spring 22 can quickly reduce the vibration generated by the slider 21, thereby reducing the vibration of the connecting plate 24 and the mounting block 25. On the guide frame 2, the first buffer spring 22, the telescopic damper 23 and the mounting block 25 quickly reduce the sliding impact of the slider 21, the connecting plate 24 and the mounting block 25 on the guide frame 2, thereby reducing the impact force of the material on the roller 3, thereby reducing the direct impact of the material on the conveyor belt and the roller 3, thereby extending the service life of the conveyor belt and the roller 3, and reducing the frequency of maintenance and replacement.

[0031] The bidirectional screw rod 11 is driven to rotate by the knob 12, and the bidirectional screw rod 11 drives the square nut 14 to slide by rotation. The square nut 14 drives one end of the adjusting rod 15 to move when it slides. Since the support plate 16 slides on the mounting frame 1 through the telescopic rod 13, the square nut 14 drives the support plate 16 to rise and fall through the adjusting rod 15 during the sliding process. The support plate 16 then drives the roller 3 to rise and fall through the guide frame 2, completing the adjustment of the horizontal height of the roller 3, and then changing the horizontal height of the conveyor belt, reducing the height difference of the material falling, and thus reducing the wear of the material on the conveyor belt and the roller 3.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
