Background

The belt conveyor is also called as a rubber belt conveyor, and is widely applied to links of transportation, packaging and the like of steel materials in the production process of the steel materials. Because the steel material is heavy, the stability and the reliability of transportation need to be ensured in the transportation process, and new requirements are provided for the roller device in the rubber belt conveyor.

In the design of the short-distance reversible belt conveyor, because frequent deformation of a belt in the belt conveyor is avoided, a flat supporting roller frame is generally adopted as an upper supporting roller frame in the design of the short-distance belt conveyor. Although the roller frame avoids the deformation of the belt, the belt on the short-distance reversible belt conveyor frequently deviates due to the fact that the flat carrier roller has no deviation adjusting function, and particularly when the reversible belt conveyor needs to be conveyed in the opposite direction after the reversible belt conveyor finishes conveying in one direction, the deviation phenomenon is easy to occur, and the stable operation and production of the belt conveyor are affected.

The deviation adjusting device in the prior art has poor material wrapping performance and deviation adjusting performance, and the included angle between the carrier rollers is too small, so that materials are concentrated at the central position, the belt at the central position and the included angle is seriously abraded, and the service life is influenced; the roller frame is adjustable, and because the working environment is severe, the adjusting parts between the adjustable roller frames are easy to be attached by dust, residue, soil, oil stains and the like, the service life is not easily influenced, and the deformation is easily caused.

Disclosure of Invention

Problem to prior art exists, the utility model provides a bearing roller device that reversible sealing-tape machine of short distance used can solve the frequent off tracking problem of the reversible sealing-tape machine of short distance, guarantees the even running of sealing-tape machine to the atress is even, reduces the wearing and tearing to the belt, is difficult to take place to warp, and the reliability is high.

The utility model discloses a realize like this, a bearing roller device that reversible sealing-tape machine of short distance used, set up the side bearing roller in center bearing roller both sides including bearing roller frame, center bearing roller and mirror symmetry, the side bearing roller is the toper bearing roller, the one end that the side bearing roller is close to center bearing roller is small-bore end, and the one end of keeping away from center bearing roller is big-bore end.

Furthermore, the central carrier roller and the two side carrier rollers are arranged on the same axis, so that materials can be uniformly distributed on a belt, and the central position of the carrier roller set is more uniformly stressed.

Furthermore, the diameter of the small-caliber end of the side carrier roller is the same as that of the central carrier roller, so that the transition from the central position to the two sides is more reasonable, the phenomenon that the included angle between the central carrier roller and the side carrier roller is too small is avoided, and the materials are accumulated at the central position and the included angle, so that the belt abrasion is aggravated.

Furthermore, the taper of the side carrier roller is 3-5 degrees, the whole size is small while the deviation adjusting effect is achieved, and uneven stress caused by overlarge angles is avoided.

Furthermore, the carrier roller frame adopts a fixed carrier roller frame, is slightly influenced by the working environment, is not easy to deform and can reliably support the carrier roller.

The utility model has the advantages and technological effect: by adopting the technical scheme, the problem of frequent deviation of steel materials during transportation in the short-distance reversible belt conveyor is solved, the stable operation of the belt conveyor is ensured, the stress is uniform, the belt is reduced in abrasion, the deformation is not easy to occur, and the reliability is high.

The side carrier rollers are arranged on two sides of the central carrier roller in a mirror symmetry mode, one end, close to the central carrier roller, of each side carrier roller is a small-caliber end, and the other end, far away from the central carrier roller, of each side carrier roller is a large-caliber end, so that the deflection of the side carrier roller towards the center is conveniently adjusted in the conveying process, and the effects of certain package material conveying and automatic deflection adjustment are achieved; the central carrier roller and the two side carrier rollers are arranged on the same axis, and the diameter of the small-caliber end of each side carrier roller is the same as that of the central carrier roller, so that materials can be uniformly distributed on the belt, the central position of the carrier roller group is more uniformly stressed, and the abrasion condition of the belt is reduced; the fixed carrier roller frame is adopted, the influence of the working environment is small, the deformation is not easy, and the carrier roller can be reliably supported.
