Three-dimensional circular tube conveying belt

Abstract

The invention belongs to conveying machines, and relates to a three-dimensional circular tube conveying belt, which solves the problem that the conventional conveying belt can be only elevated upwards within the range of between 0 and 90 degrees. The three-dimensional circular tube conveying belt is implemented by the following special method: both ends of a bearing belt and a backhaul belt are parallel, and the conveying belt is changed into a tubular shape from a parallel shape by a conveyor rounder, so that conveyed materials are wrapped in a tube hermetically; a roller group or a single roller with a circular shape, a square shape, an oval shape, a U shape, a parallel shape and the like is used to overcome the lateral compression and clamping force which are generated by the accumulation of the materials, so that the conveying belt can make a turn in a three-dimensional direction, namely in any directions of horizontal and vertical surfaces, at an angle of between 0 and 360 degrees; and two to three layers of canvas and tyre fabrics which are prepared from nylon, polyester-nylon, terylene, carbon fibers, basalt fibers, aramid fibers and polysulfonamide by dipping gum or ropes arranged at certain intervals are arranged between upper covering glue and lower covering glue to serve as skeleton layers of the conveying belt, and the skeleton layers of the conveying belt are overlaid with side glue mutually to form the conveying belt. The three-dimensional circular tube conveying belt has the advantages of high strength, flexibility, long service and wide application.

Description

technical field [0001] The invention relates to a conveyor belt used on a circular tube conveyor, more precisely, to a conveyor belt with two to three layers of skeleton, light and thin, strong, soft, good performance in bending into a circle, and long service life. The three-dimensional direction is a three-dimensional circular tube conveyor belt that can turn from 0 to 360° in any direction on the horizontal and vertical planes. Background technique [0002] At present, the trough conveyor uses the conveyor belt to convey materials in a "V" shape, and cannot turn. It can only be transported upwards under the condition of an inclination angle of ≤17°. The corrugated sidewall conveyor belt and bucket elevator can only be upwards. 0~90° conveying, none of them can turn horizontally or convey downward. At present, the conveyor belt uses four to ten layers of dipped nylon, polyester nylon, and polyester canvas as the skeleton layer. The number of canvas layers is directly pro...

AI Technical Summary

Problems solved by technology

It can be bent and rounded, and the belt is strong, but due to the large specificity of the steel wire rope, the belt body is heavy, and the energy consumption is large. Due to the steel wire rope’s rigidity, the belt body is stiff, the flexibility is poor, the diameter of the driving drum is large, the kinetic energy is high, and the turning radius is large. The maximum cannot exceed 30°

Because it has no transverse skeleton, it is easy to tear. Under the condition of damaged covering glue or acid-base environment, the steel wire rope is easy to rust and break, causing safety accidents, and the lead is difficult to connect and difficult to install.
