Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a pressure wheel of a belt conveyor. Background Art

[0002] In the automated process of waste sorting and transportation, belt conveyors, as efficient and continuous conveying equipment, play a vital role. They enable rapid and stable waste transport, significantly improving waste handling efficiency. However, during actual operation, preventing the conveyor belt from drifting off the idlers due to tension has become a pressing issue. To this end, pressure rollers are widely used on belt conveyors. Their primary function is to apply pressure to the conveyor belt, ensuring it runs closely against the idlers, thereby preventing drifting and ensuring stable and reliable transmission.

[0003] The traditional belt conveyor pulley design usually uses two wheels connected by a height-fixed connecting shaft. The connecting shaft ensures the stable installation of the pulley on the belt conveyor, and while supporting the pulley, it prevents the pulley from shaking or shifting during operation. However, in various transportation scenarios of garbage sorting, this design has exposed some significant limitations. For example, when transporting garbage of different heights after sorting, when the height of the processed garbage material exceeds the height of the connecting shaft between the pulleys, the material will be difficult to be smoothly transported through the belt conveyor. During transportation, the material may accumulate and become blocked, and may even cause the belt conveyor to shut down, seriously affecting the continuity and efficiency of garbage treatment. Utility Model Content

[0007] Furthermore, in order to facilitate the fixed installation of the pressure roller and adjust the clamping force, one end of the support shaft is fixedly connected to an adjustment plate, the surface of the adjustment plate is threadedly connected to a lifting screw rod 2, and the end of the lifting screw rod 2 is rotatably installed with a fixed plate, and positioning holes are opened on both sides of the surface of the fixed plate.

[0008] Furthermore, in order to enable the pressure pulley to limit the conveyor belt on the belt conveyor and prevent it from deflecting, a limiting ring is fixedly installed on one side of the surface of the pressure pulley.

[0009] Furthermore, in order to facilitate the twisting and rotation of the transmission rod and the lifting screw rod 2, twisting blocks are fixedly installed on the surface of the transmission rod and one end of the lifting screw rod 2.

[0010] Furthermore, in order to guide the material transported on the belt conveyor and prevent it from moving under the belt pressure wheel, a support frame is fixedly connected to one side of the surface of the support shaft, and a guide rod is fixedly connected to one end of the support frame.

[0011] Furthermore, in order to increase the friction between the pressure pulley and the conveyor belt, an anti-skid pad is fixedly installed on the surface of the pressure pulley.

[0012] Furthermore, in order to achieve precise adjustment of the height of the lifting screw rod 2, a scale plate is fixedly mounted on one side of the surface of the adjustment plate.

[0013] The beneficial effects of the present invention are as follows: a stable connection between the two pressure rollers is achieved through the support rod and the internal transmission rod, and by twisting the transmission rod, it drives the lifting screw to rotate and lift, thereby achieving adjustment of the height of the support rod and the transmission rod connected between the two pressure rollers. Therefore, when transporting materials of different heights on the pulleys, it can effectively avoid that the materials cannot pass through the belt conveyor smoothly due to height problems, increase the applicability of the pressure roller on the belt conveyor when facing materials of different heights, and can reduce the friction and collision between the materials and the pressure roller, thereby greatly improving the continuity and efficiency of garbage sorting and transmission on the belt conveyor.
