Description

Technical Field

[0001] The utility model relates to the technical field of strip steel conveying of an uncoiler loading belt, in particular to a special roller set for a belt conveyor applicable to a cold rolling strip uncoiling treatment line. Background Technique

[0002] A belt conveyor is a continuous conveying machine with a conveyor belt as the traction and load-bearing component. The conveyor belt winds around the driving roller and various redirecting rollers, and is given an appropriate tension by a tensioning device. During operation, under the drive of the driving device, through the friction and tension between the roller and the conveyor belt, the conveyor belt runs, and the material is continuously sent onto the conveyor belt and moves along with the conveyor belt, thereby realizing the conveyance of the material.

[0003] For example, the Chinese authorized patent (belt conveyor) with the publication number of CN203497590U: includes a frame and a belt installed on the frame. The belt conveyor further includes a bracket and a pressure roller. The bracket is fixed on the frame. The pressure roller is located above the belt and can rotate relative to the bracket. The bracket is fixed on both sides of the frame. The belt conveyor further includes a rotating shaft installed on the bracket. The pressure roller is sleeved on the rotating shaft. The belt conveyor can prevent the belt from bulging or tipping over, thereby preventing the belt from being damaged, prolonging the service life of the belt, and ensuring the normal conveying operation of the belt conveyor.

[0004] However, in the above-mentioned prior art, the belt roller set designed for the unit is extremely prone to the phenomenon of belt deviation during the forward rotation during loading, until the strip steel is pulled and deviated to the center line area or the strip is stacked, restricting the normal operation of the next process. Therefore, it does not meet the existing requirements. For this reason, we propose a special roller set for a belt conveyor applicable to a cold rolling strip uncoiling treatment line. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special roller set for a belt conveyor applicable to a cold rolling strip uncoiling treatment line, so as to solve the problem that in the prior art, the belt roller set designed for the unit is extremely prone to the phenomenon of belt deviation during the forward rotation during loading, until the strip steel is pulled and deviated to the center line area or the strip is stacked, restricting the normal operation of the next process as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a special roller set for a belt conveyor applicable to a cold rolling strip uncoiling treatment line, including a conveyor. A frame is arranged on the conveyor. A support frame is installed at the bottom of the frame. A moving wheel is installed at the bottom of one side of the support frame, and two moving wheels are installed.

[0007] It further includes:

[0008] A transport belt is arranged inside the frame, and a drive motor is installed on the front end surface of the frame;

[0009] A main transmission roller is arranged on one side below the transport belt, a passive roller is arranged on the other side below the transport belt, a support roller is arranged between the main transmission roller and the passive roller, and two support rollers are arranged.

[0010] Preferably, a steering roller is arranged on one side below the passive roller, a tension roller is arranged below the steering roller, and an adjusting screw rod is installed on the tension roller.

[0011] Preferably, a lower roller is provided below the roller.

[0012] Preferably, the surfaces of the main drive roller, passive roller, tension roller, support roller, steering roller and lower support roller are all provided with connecting surfaces, and the insides of the main drive roller, passive roller, tension roller, support roller, steering roller and lower support roller are all installed with rotating shafts.

[0013] Preferably, the upper surface of the connecting surface is provided with a trapezoidal positioning groove, and two trapezoidal positioning grooves are provided, and the lower surface of the conveying belt is provided with a trapezoidal block, and the trapezoidal block is plug-connected with the inside of the trapezoidal positioning groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model comprises a belt roller group consisting of a main drive roller, a passive roller, a roller, a tension roller, a steering roller and a lower roller. A connecting surface is provided on the surface of the roller body, and a trapezoidal positioning groove is provided on the connecting surface. The corresponding area of ​​the belt fits the trapezoidal block. After a certain tensioning force is given to the belt, the trapezoidal block of the belt is completely fitted in the positioning groove of the roller group, so as to limit the lateral displacement of the belt and prevent the belt from being deviated due to the friction of the strip steel. The trapezoidal fitting surface can effectively restrain the lateral displacement of the belt and has a return function, so as to prevent product quality accidents caused by the deviation of the belt, thereby ensuring the normal operation of the unit, effectively improving the unit completion rate, greatly reducing spare parts and maintenance costs, and solving the problem that the belt roller group designed for the unit in the prior art is very likely to have the belt deviation phenomenon in the forward use when loading, until the strip steel is pulled and offset to the center line area or the plate and strip are accumulated, thus restricting the normal operation of the next process.

[0016] 2. By installing an adjusting screw on the tension roller, the rotation of the adjusting screw drives the distance between the tension roller and the steering roller to be adjusted, so as to adjust the tension and improve the flexibility and convenience of its use.
