Description

Technical Field

[0001] This utility model relates to the field of idler roller technology, and in particular to an idler roller with an adjustable support base height. Background Technology

[0002] Idler rollers play a crucial supporting and friction-reducing role in belt conveyor systems, and are important components that ensure the efficient, stable, and long-life operation of the conveyor. Idler rollers replace the sliding friction between the conveyor belt and the supporting structure with rolling friction, which greatly reduces running resistance and thus effectively saves energy consumption. Idler rollers are evenly distributed on the conveyor, which can stably support the conveyor belt and the materials it carries, ensuring the smooth operation of the conveyor belt and preventing sagging or deviation. High-quality idler rollers can ensure the smooth operation of the conveyor belt, reduce vibration and noise, and improve conveying efficiency and the comfort of the working environment.

[0003] However, the idler rollers commonly available on the market have some obvious drawbacks: First, the support base of the idler roller cannot be height adjusted, which makes it difficult to flexibly adjust to adapt to changes in different scenarios; second, the disassembly process of the idler roller is extremely cumbersome and cannot be quickly disassembled, which consumes a lot of time and effort when maintenance or replacement of the idler roller is required, seriously affecting work efficiency and causing many inconveniences in the process of use; therefore, it is very necessary to design an idler roller with an adjustable support base. Utility Model Content

[0004] The purpose of this invention is to provide a roller with an adjustable support base to solve the defects of existing roller support bases that cannot be adjusted in height and rollers that are difficult to disassemble.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a roller with an adjustable support base, including a portal-shaped support base, a positioning hole, a support side plate, a sliding plate, a sliding block, a threaded support shaft, a square fixing plate, and a dovetail-shaped fixing block. A fixing support block is fixedly connected to the portal-shaped support base. A threaded support shaft is slidably connected to a through hole in the fixing support block. A third nut is threadedly connected to the threaded support shaft. A handle is fixedly connected to the third nut. The threaded support shaft is slidably connected to the through hole in the portal-shaped support base.

[0006] As a further technical solution of this utility model, a support side plate is fixedly connected to the portal-shaped support base, a positioning hole is opened on the portal-shaped support base, a square fixing plate is fixedly connected to the portal-shaped support base by bolts, and a threaded support shaft is slidably connected in the through hole of the square fixing plate.

[0007] As a further technical solution of this utility model, a dovetail-shaped fixing block is fixedly connected to the supporting side plate, and a sliding plate is slidably connected to the dovetail-shaped fixing block. One end of a cylindrical roller is engaged in the through hole opened on the sliding plate.

[0008] As a further technical solution of this utility model, one end of the cylindrical roller is fixedly connected to a first threaded shaft, and a first nut is connected to the first threaded shaft by threaded engagement.

[0009] As a further technical solution of this utility model, a second threaded shaft is fixedly connected to the other end of the cylindrical roller, and a second nut is connected to the second threaded shaft through threaded engagement.

[0010] As a further technical solution of this utility model, a lower connecting block is fixedly connected to the threaded support shaft, one end of a second spring is fixedly connected to a groove opened on the lower connecting block, the other end of the second spring is fixedly connected to a second snap-fit ​​block, the second snap-fit ​​block is in close contact with the second excitation block, the second excitation block is slidably connected to a groove opened on the sliding block, the sliding block is slidably connected to a sliding groove opened on the lower connecting block, and the second snap-fit ​​block is slidably connected to a groove opened on the lower connecting block.

[0011] As a further technical solution of this utility model, the sliding block is slidably connected in the groove opened in the upper connecting block, one end of the first spring is fixedly connected in the groove opened in the upper connecting block, the other end of the first spring is fixedly connected to the first snap-fit ​​block, the first snap-fit ​​block is close to the first excitation block, the first excitation block is slidably connected in the groove opened in the sliding block, the first snap-fit ​​block is slidably connected in the groove opened in the upper connecting block, and the other end of the cylindrical roller is snapped into the upper connecting block and the lower connecting block.

[0012] This utility model provides an adjustable height roller with a support base. Its advantages are as follows: pulling the handle rotates the third nut, which in turn moves the threaded support shaft up and down in the through hole of the square fixing plate. This, in turn, pushes the sliding plate to slide on the dovetail-shaped fixing block, thus adjusting the height of the cylindrical roller. This allows for more flexible adjustment to adapt to different scenarios, and the operation is simple, saving a significant amount of time. When disassembling the cylindrical roller, pressing the first and second trigger blocks simultaneously presses the first locking block into the groove of the upper connecting block and the second locking block into the groove of the lower connecting block. The sliding block, no longer restricted by the first and second locking blocks, can slide out along the grooves of the upper and lower connecting blocks, allowing the upper connecting block to be removed, ultimately achieving the disassembly of the cylindrical roller. The disassembly process is simple and convenient, requiring no training for quick disassembly. This saves considerable time and effort when maintaining or replacing the roller, improving work efficiency. Attached Figure Description
