Technical Field

The invention relates to a circular tube belt conveyor, and belongs to the technical field of material conveying.

Background

The circular tube belt conveyor is a special belt conveyor developed on the basis of a groove-shaped belt conveyor, and is equipment for guiding a flat conveying belt into a circular tube shape by applying a forced force through a carrier roller group so as to seal conveyed materials in the circular tube, thereby realizing closed conveying in the whole conveying line.

The round pipe belt conveyor has the following advantages: (1) the conveyer belt adopted by the circular tube belt conveyer is close to a common conveyer belt, so that the circular tube belt conveyer is suitable for the use habit of users and is easily accepted by users, and the conveyer belts adopted by other types of closed conveyer belt conveyers are greatly different from a common belt conveyer;

(2) the complete closed conveying of the bearing section and the return section can be realized, the material leakage, material sprinkling and the like can be avoided in principle, and the environmental protection requirement can be met;

(3) because the conveying material is isolated from the outside, the conveying material can be prevented from being mixed with external sundries, and the conveying material is prevented from being damaged by rain, sunshine and the like.

(4) The flexible layout design can be realized, the turning in the small-radius three-dimensional space can be realized, the establishment of an intermediate transfer station and the investment and maintenance cost of corresponding auxiliary equipment are avoided, the flexible layout design is particularly suitable for the construction of a conveying line in a complex environment with narrow space or obstacles and the like, the conveying distance is shortened, and the total construction cost of a project is reduced.

In the actual conveying process, due to the existence of various factors, the conveying belt deforms due to various uneven stress, and the deformation inevitably affects the conveying of the materials.

Disclosure of Invention

Aiming at the defects, the invention aims to provide the circular tube belt conveyor which is reasonable in structure and can realize efficient and stable material conveying.

The technical scheme adopted by the invention is as follows: the round pipe belt conveyor comprises a conveying belt (1) and a regular polygon carrier roller group (2) which changes the conveying belt (1) from a flat shape to a U shape and then to an O shape, wherein symmetrical cross-shaped supporting rods (3) are arranged in the O-shaped conveying belt (1), and the cross-shaped supporting rods (3) are circular in cross section.

The cross-shaped supporting rod (3) comprises a rod body (31) and a rolling ball (32) arranged at the front end of the rod body (31), the rolling ball (32) is rotatably connected to the rod body (31), and the rolling ball (32) is in contact with the inner wall of the conveying belt (1).

The inner wall of the conveying belt (1) is provided with a groove profile corresponding to the rolling balls (32).

The regular polygon carrier roller group (2) is a regular hexagon carrier roller group.

The invention has the advantages that: according to the invention, the cross-shaped supporting rods are arranged on the inner wall of the conveying belt, and the supporting rods are matched with the regular polygon carrier roller group inside and outside, so that the conveying belt is stressed more uniformly, and the conveying belt can be ensured to stably maintain good service performance for a long time.

Detailed Description

The circular tube belt conveyor comprises a conveying belt 1 and a regular polygon carrier roller group 2 for changing the conveying belt 1 from a flat shape to a U shape and then to an O shape, wherein symmetrical cross-shaped supporting rods 3 are arranged in the O-shaped conveying belt 1, and the cross-shaped supporting rods 3 are circular in cross section.

The cross-shaped supporting rod 3 comprises a rod body 31 and a rolling ball 32 arranged at the front end of the rod body 31, the rolling ball 32 is rotatably connected to the rod body 31, and the rolling ball 32 is in contact with the inner wall of the conveying belt 1.

The inner wall of the conveyor belt 1 is provided with a groove profile corresponding to the rolling balls 32.

The regular polygon carrier roller group 2 is a regular hexagon carrier roller group.

The working process of the invention is as follows: the inner wall of the O-shaped conveying belt 1 is provided with the cross-shaped supporting rod 3, due to the existence of the rolling balls 32, the rolling balls 32 are in rolling connection with the inner wall of the conveying belt 1, the stress environment of the inner wall of the conveying belt 1 is improved, the conveying belt 1 is uniformly stressed by matching with the regular polygon carrier roller group 2, and the conveying performance of the conveying belt 1 is improved.

The arrangement of the groove profile further ensures that the rolling of the rolling ball 32 is limited within the groove profile, so that the rolling ball 32 only can rotate by itself and cannot rotate along the inner wall of the conveying belt 1, and the conveying performance of the conveying belt is further ensured.

The regular polygon carrier roller group 2 of the invention is preferably a regular hexagon carrier roller group or regular polygons with other structural forms, which is determined according to actual conditions.
