Description

Technical Field

[0001] This utility model relates to the field of roller screens, and in particular to a roller screen that facilitates adjustment of the roller gap. Background Technology

[0002] A roller screen is a device that uses multiple parallel rollers rotating in the same direction to screen materials through a fixed gap between the rollers. Its core working principle is that materials smaller than the gap pass directly down, while lumpy or sticky materials larger than the gap are conveyed forward and discharged by the rotation of the rollers. This unique working method makes it particularly good at handling sticky, large materials that are prone to clogging vibrating screens. It has significant advantages such as stable operation, impact resistance, and anti-clogging. Therefore, it is widely used in coarse screening operations in metallurgical sintering, coal, mining, and waste treatment.

[0003] The existing roller column structure of roller screens is generally fixed directly to the support frame with bolts. When it is necessary to adjust the roller gap of the roller screen, the bolts need to be removed and the roller column moved, which is very troublesome.

[0004] Therefore, those skilled in the art have provided a roller screen with an easily adjustable roller gap to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a roller screen with an adjustable roller gap, in which the roller column can be adjusted via an electric actuator.

Two supporting sliding plates 2 are fixedly installed on the front and rear sides of the upper end of the support body 1. The sliding grooves on the two supporting sliding plates 2 allow the ends of the rollers to slide inside. Fixing blocks 3 are installed on the upper center of the two supporting sliding plates 2 via fixing bolts 11. The top of the fixing blocks 3 is rigidly connected to the support plate 4, which provides support. First electric push rods 5 are fixed on both sides of the two fixing blocks 3. Each output end of the first electric push rod 5 is connected to a first sliding block 6. The four first sliding blocks 6, driven by the electric push rods, can move precisely and synchronously along the sliding grooves of the supporting sliding plates 2. First rollers 12 for screening materials are fixedly installed on opposite sides of the two first sliding blocks 6. Mounting plates are rotatably installed at the front and rear ends of the first rollers 12, facilitating their movement with the sliding blocks. When the sliding block 6 moves, it can adjust the gap of the roller screen. In order to drive the first roller column 12 to rotate, the two first sliding blocks 6 on the front side are bolted with first mounting plates 13. Each first mounting plate 13 is equipped with a first motor 14 at the front end. The output end of the first motor 14 is snapped to the front end of the first roller column 12 so that the first motor 14 can provide rotational power. On the outside of the four first sliding blocks 6, that is, on the side away from the first electric push rod 5, a moving module 7 is bolted to each other.
