Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a redirecting roller used for a belt conveyor. Background Art

[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, convenient maintenance and standardized parts. They are widely used in mining, metallurgy and coal industries to convey loose materials or finished goods. According to the conveying process requirements, they can be conveyed by a single unit, or they can be composed of multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of production lines. The redirecting roller is also called the guide roller. The redirecting roller is an important component of the belt conveyor. It mainly plays the role of changing the running direction of the conveyor belt and tensioning the conveyor belt in the conveyor.

[0003] During operation, the existing conveyor belt is easily subjected to radial thrust from the roller, and is prone to deviation. It needs to be adjusted in time. If it is not adjusted in time, it will not only cause material to fall and pollute the working environment, but also cause the edge of the belt and the frame to wear each other, thereby increasing the probability of sudden belt breakage, affecting the normal smooth production and the stability of process product quality. At the same time, during the operation of the existing redirecting roller, particulate matter will be attached or adhered when the drum rotates, and the particulate matter needs to be cleaned in time. If the attached or adhered particulate matter is not cleaned, it is easy to affect the transmission of the conveyor belt on the surface of the drum, thereby affecting its service life and normal transmission operation.

Example 2

[0033] This embodiment is based on the embodiment 1, in order to further improve the service life of the roller 2, avoid damage to the cylinder 21 due to wear, and at the same time, to enhance the friction of the belt in the belt conveyor during operation, a wear-resistant surface rubber layer is provided on the outer circumferential surface of the cylinder 21 in the roller 2. The wear-resistant surface rubber layer can also reduce the wear problem of the belt.

[0034] The utility model adopts a redirecting roller for a belt conveyor, wherein the electric telescopic rod 72 and the photoelectric sensor are commonly used equipment in the existing market. They are applied to the utility model for the purpose of convenient control, and no improvement is made to them themselves. The corresponding model can be selected according to the specific situation as long as the use requirements are met. Therefore, the specific model is not described in detail.

[0035] In the specific application process, the redirecting roller described in the utility model can be used to install the roller bracket 1 in the supporting device of the existing conveyor, and connect it to the central axis 3 in the roller assembly through the existing drive motor, so as to achieve the purpose of driving the roller 2 to rotate. Since the roller 2 in the roller assembly is composed of a cylinder 21 and a web 22 to form a detachable connection structure, the cylinder 21 and the web 22 can be easily assembled and disassembled through the connecting piece 23. Since the connecting piece 23 adopts a self-locking screw, the problem of the connecting piece 23 falling off during operation can be avoided. Since the roller 2 adopts a detachable connection method, it can prevent the problem of breakage caused by wear during use, and it is convenient to replace it in time without the need for overall replacement. This can save the cost of use and reduce the maintenance cost. At the same time, since a cleaning mechanism 6 is also provided, when it is necessary to clean the cylinder 21 during operation, it can be cleaned in advance. By adjusting the distance between the cleaning scraper 631 and the cylinder 21 through the adjusting bolt 634, under the action of the transmission assembly 62, the driven wheel 623 is driven to rotate through the driving wheel 624, and the rotating screw rod 621 is driven to rotate synchronously. During the rotation of the rotating screw rod 621, the connecting screw sleeve 635 threaded on the rotating screw rod 621 is driven to continuously reciprocate back and forth along the rotating screw rod 621. In addition, since a guide rod 636 is also provided in the support frame 61, and the connecting screw sleeve 635 is slidably sleeved on the guide rod 636, the configured guide rod 636 can not only play a guiding role, but also a supporting role. During the movement of the connecting screw sleeve 635 along the guide rod 636, the cleaning scraper 631 is used to clean the surface of the cylinder 21 in the roller 2, effectively scraping off the debris particles that are adhered, so as to ensure the normal conveying and service life of the conveyor belt; in addition, through the configured automatic deviation correction mechanism 7, the position sensor 71 and the electric telescopic rod 72 are respectively connected to the control system configured for the existing belt conveyor. During operation, when the position sensor 71 detects that the belt in the belt conveyor is deviated, the electric telescopic rod 72 is connected and started through the existing control system, and the deviation correction wheel 74 in the automatic deviation correction mechanism 7 is used to automatically correct the web 22 in the roller 2. The specific deviation correction method is: since a micro motor 75 for driving the rotation of the deviation correction support plate 73 is provided, the micro motor 75 is used to drive the deviation correction wheel 74 to rotate, and the rotation direction is required to be opposite to the rotation direction of the web 22, so as to achieve the deviation correction purpose. This can solve the problem that the belt in the belt conveyor is prone to deviation due to the radial thrust of the roller 2 when it is running.

[0036] To sum up, the redirecting roller described in the utility model is adopted, and the roller assembly adopts a detachable connection structure, which is not only convenient for disassembly and replacement, but also can reduce the use and maintenance costs. The cleaning mechanism 6 and the automatic deviation correction mechanism 7 are configured to solve the cleaning and anti-deviation problems of the redirecting roller, so as to better meet the use requirements. The overall structure is simple, the layout is reasonable, the operation is convenient, and it is suitable for promotion and application.
