Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conveyor belt technology, specifically relating to a tubular conveyor belt. Background Technology
[0002] With increasingly stringent national environmental protection requirements, tubular conveyor belts have gained widespread use and rapid development in material transportation due to their ability to provide enclosed conveying and reduce pollution caused by material flying during transport.
[0003] However, many problems still arise during use, troubling tubular conveyor belt manufacturers and users. After visiting customers, tubular conveyor belt manufacturers found a common problem with tubular conveyor belts after long-term use: the edges of the tubular conveyor belt are prone to delamination.
[0004] Tubular conveyor belts are formed by vulcanization bonding of multiple layers. During use, tubular conveyor belts need to switch between flattening and tube forming states. During tube forming, the two sides of the tubular conveyor belt will squeeze and collide with each other. Under long-term repeated stress, the multi-layer structure of the tubular conveyor belt will crack and delaminate, causing the conveyor belt to fail to maintain a good sealed state after tube forming, allowing the contents to escape and affecting the environment. Utility Model Content
[0005] This utility model provides a tubular conveyor belt to solve the technical problem that existing tubular conveyor belts are prone to cracking and delamination on both sides after long-term use, which affects environmental protection. This utility model includes: a bottom cover adhesive; An elastic layer is laid inside the lower cover adhesive; The upper cover adhesive is located above the lower cover adhesive; Several steel wire ropes are spaced apart between the upper cover rubber and the lower cover rubber, and the diameter of the steel wire ropes on both sides is smaller than the diameter of the steel wire rope in the middle.
[0006] In this invention, after the tubular conveyor belt is formed, the upper cover rubber is inside to support the goods, and the lower cover rubber is outside. The diameter of the steel wire rope gradually decreases from the middle to both sides, allowing the upper and lower cover rubber to have a larger contact area. Furthermore, the lower strength of the small-diameter steel wire rope makes it easier for the two sides of the tubular conveyor belt to deform when they come into contact during tube formation, thereby relieving excessive compressive force and preventing edge cracking.
[0007] Furthermore, the top corners of the lower cover adhesive and the upper cover adhesive are rounded. The beneficial effect of this step is that the rounded corners have good guiding properties, which makes it easier for the two sides of the tubular conveyor belt to stagger vertically during the tube forming process.
[0008] Furthermore, the spacing between adjacent steel wire ropes in the middle is smaller than the spacing between adjacent steel wire ropes on both sides. The beneficial effect of this step is that it increases the contact area between the upper and lower cover rubber on both sides.
[0009] Furthermore, a rigid layer is also laid inside the top cover adhesive. The rigid layer is located in the middle of the top cover adhesive, and the width of the rigid layer does not exceed 40% of the width of the top cover adhesive. The beneficial effect of this step is that the rigid layer is located in the middle and helps to support the goods.
[0010] Furthermore: the rigid layer is an arc surface, with the apex of the arc facing the lower cover adhesive. The beneficial effect of this step is that the curvature of the rigid layer is adapted to the tube shape of the tubular conveyor belt.
[0011] Furthermore: one end of the upper cover adhesive is provided with a slope, and the other end of the lower cover adhesive is also provided with a slope. The beneficial effect of this step is that the staggered slopes have a guiding effect during pipe forming.
[0012] The beneficial effects of this utility model are: This application reduces the diameter of the edge steel wire rope to decrease the rigidity of the tubular conveyor belt edge. This allows the belt to release the extrusion force through its own deformation when it is squeezed and collided during the tube forming process, thus avoiding edge cracking and delamination, extending the service life of the tubular conveyor belt and maintaining its sealing properties.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.
[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0020] Implementation of this application, for example Figure 1 and Figure 2As shown, a tubular conveyor belt is provided.
[0021] The first embodiment of this application is as follows, including: a lower cover adhesive 1; Elastic layer 11 is laid inside the lower cover adhesive 1. Elastic layer 11 is generally woven fabric or woven mesh, and the woven material is nylon or aramid fiber, etc. The upper cover adhesive 2 is located above the lower cover adhesive 1; Several steel wire ropes 3 are spaced apart between the upper cover rubber 2 and the lower cover rubber 1, and the diameter of the steel wire ropes 3 on both sides is smaller than the diameter of the steel wire rope 3 in the middle.
[0022] In this application, after the tube is formed, the upper cover rubber 2 is inside and used to carry the goods, while the lower cover rubber 1 is outside. The diameter of the steel wire rope 3 gradually decreases from the middle to both sides, allowing the upper cover rubber 2 and the lower cover rubber 1 to have more contact area. Moreover, the small diameter steel wire rope 3 has low strength, making it easier for the two sides of the tubular conveyor belt to deform when they come into contact during tube formation, so as to relieve excessive extrusion pressure and avoid edge cracking.
[0023] Based on the above technical solution, the top corners of the lower cover adhesive 1 and the upper cover adhesive 2 are rounded. The rounded corners have good guiding properties, which makes it easier for the two sides of the tubular conveyor belt to stagger vertically when forming the tube.
[0024] Based on the above technical solution, the adjacent spacing of the middle steel wire rope 3 is smaller than the adjacent spacing of the steel wire ropes 3 on both sides, so that the contact area of the upper cover rubber 2 and the lower cover rubber 1 on both sides is larger and the vulcanization bonding is tighter.
[0025] Based on the above technical solution, a rigid layer 21 is also laid inside the top cover adhesive 2. The rigid layer 21 is located in the middle of the top cover adhesive 2, and the width of the rigid layer 21 does not exceed 40% of the width of the top cover adhesive 2. The rigid layer 21 is located in the middle, is impact resistant, and is used to help support the goods.
[0026] Based on the above technical solution, the rigid layer 21 is an arc surface, with the top of the arc facing the lower cover adhesive 1. The curvature of the rigid layer 21 is adapted to the tube shape of the tubular conveyor belt, so that it can maintain the tube's circular shape and not deform when containing heavy objects.
[0027] Based on the above, in Embodiment 2 of this application, one end of the upper cover adhesive 2 is provided with a slope 4, and the other end of the lower cover adhesive 1 is also provided with a slope 4. The staggered slopes 4 have a better guiding effect when forming the pipe.
