Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to the troughing of conveyor belts, specifically a belt pressure blocking device for belt conveyors. Background Technology
[0002] Belt conveyors transport materials by rotating a conveyor belt. When selecting a conveyor belt, depending on the actual stress conditions, sometimes a high strength is required; otherwise, the strength requirement for actual use cannot be met. For the same material, a higher belt strength requires a thicker conveyor belt. A thicker conveyor belt results in poor troughing properties, especially during initial installation, making troughing difficult and requiring temporary external force to force the conveyor belt into the idler roller assembly to form a trough.
[0003] Currently, when forcibly troughing a conveyor belt, rollers are often used to press down on the middle of the conveyor belt, forming the bottom of the trough. Although this method forms a trough, the conveying efficiency can be affected in the initial stage of equipment operation due to the arrangement of the rollers and related structures. Moreover, as described in the patent application number 2023205955371, this type of structure is relatively complex, leading to increased operating costs. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a belt conveyor pressure blocking device, which not only achieves belt troughing in the initial stage of use, but also has a simple structure and low operating cost.
[0005] This utility model is achieved through the following technical solution: a belt conveyor belt blocking device is provided, including a main frame fixedly connected to the frame of the belt conveyor, and a left blocking roller and a right blocking roller installed on the main frame. The left blocking roller is located above the left edge of the conveyor belt of the belt conveyor, and the round roller face of the left blocking roller forms an obstruction to the upward movement of the left side of the conveyor belt. The right blocking roller is located above the right edge of the conveyor belt of the belt conveyor, and the round roller face of the right blocking roller forms an obstruction to the upward movement of the right side of the conveyor belt.
[0006] In use, this solution provides mounting support for the left and right guide rollers via a main frame that is fixed to the conveyor frame. These rollers then block and limit the upper edges of the left and right sides of the conveyor belt, preventing it from shifting upwards and achieving forced troughing. Furthermore, the main frame and the left and right guide rollers form a single unit that can be directly applied to existing conveyors without requiring structural modifications.
[0007] As optimization, the left blocking roller and the right blocking roller are both inclined, and the end close to each other is lower than the end far away from each other. The optimization scheme of the left blocking roller and the right blocking roller is inclined, and when the side edge of the conveying belt moves upward, the blocking of the conveying belt is better, the side edge of the conveying belt is prevented from sliding along the roller surface of the left blocking roller and the right blocking roller, and the blocking effect of the conveying belt is guaranteed.
[0008] As optimization, the left blocking roller and the right blocking roller are both inclined, and the end close to each other is lower than the end far away from each other. The optimization scheme of the left blocking roller and the right blocking roller is inclined, and when the side edge of the conveying belt moves upward, the blocking of the conveying belt is better, the side edge of the conveying belt is prevented from sliding along the roller surface of the left blocking roller and the right blocking roller, and the blocking effect of the conveying belt is guaranteed.
[0009] As optimization, the left blocking roller and the right blocking roller are both inclined, and the end close to each other is lower than the end far away from each other. The optimization scheme of the left blocking roller and the right blocking roller is inclined, and when the side edge of the conveying belt moves upward, the blocking of the conveying belt is better, the side edge of the conveying belt is prevented from sliding along the roller surface of the left blocking roller and the right blocking roller, and the blocking effect of the conveying belt is guaranteed.
[0010] As optimization, the left blocking roller and the right blocking roller are both inclined, and the end close to each other is lower than the end far away from each other. The optimization scheme of the left blocking roller and the right blocking roller is inclined, and when the side edge of the conveying belt moves upward, the blocking of the conveying belt is better, the side edge of the conveying belt is prevented from sliding along the roller surface of the left blocking roller and the right blocking roller, and the blocking effect of the conveying belt is guaranteed.
[0011] As optimization, the left blocking roller and the right blocking roller are both inclined, and the end close to each other is lower than the end far away from each other. The optimization scheme of the left blocking roller and the right blocking roller is inclined, and when the side edge of the conveying belt moves upward, the blocking of the conveying belt is better, the side edge of the conveying belt is prevented from sliding along the roller surface of the left blocking roller and the right blocking roller, and the blocking effect of the conveying belt is guaranteed.
[0012] The beneficial effects of the utility model are that the left blocking roller and the right blocking roller are used to block the upward movement of the side edge of the conveying belt, so that the forced grooving is realized, and the blocking of the conveying material is avoided, and after the grooving of the conveying belt, the positions of the left blocking roller and the right blocking roller can be adjusted upward and used as anti-deviation rollers.
