Long-life extension-resistant threaded mesh belt

Abstract

The invention belongs to a long-life extension-resistant threaded mesh belt. The technical scheme includes that the long-life extension-resistant threaded mesh belt comprises bunching rods (2) which are sequentially connected with joint plates (1) on one side, thread lines (3) and the joint plates (1) on the other side. The long-life extension-resistant threaded mesh belt is characterized in that arch-shaped protruding heads (4) are manufactured at two ends of the bunching rods (2) and fixedly connected with the bunching rods (2) and the joint plates (1), the distance between top portions (41) of the protruding heads and external end faces (13) is smaller than that between external protruding faces (16) and the external end faces (13), inner ends (11) of the joint plates (1) are fixedly connected with the thread lines (3), each of outer ends (12) of the joint plates (1) comprises the external end face (13), an external end folding position (14), an external protruding position (15) and the external protruding face (16), and a hub friction bar (5) is correspondingly arranged outside of each of the external protruding faces (16). The long-life extension-resistant threaded mesh belt has the advantages of firmer structure and longer service life.

Description

[0001] technical field [0002] The invention relates to a mechanical conveying device, in particular to a high-life anti-extrusion spiral mesh belt. Background technique [0003] The existing spiral conveying mesh belt has great defects and deficiencies in the structure of the connecting plate and the solder joints between the connecting plate and the string rods. Because the riveted joint and the connecting plate are only partially connected when welding the bending edge, there is no 360° fusion welding, so that the mesh belt structure is not strong enough; when the mesh belt is squeezed, the hub friction strip directly acts on the end of the string rod At the welding point of the riveting head, it is easy to cause the welding point to be squeezed and damaged. In a word, the solder joints are not strong enough and subjected to extrusion force, so that the existing mesh belt will break at the solder joints. Therefore, the service life is short, and the conveyor belt n...

Problems solved by technology

[0003] The existing spiral conveying mesh belt has great defects and deficiencies in the structure of the connecting plate and the solder joints between the connecting plate and the string rods. Because the riveted joint and the connecting plate are only partially connected during welding, no 360° fusion welding is formed, which makes the mesh belt structure not strong enough; when the mesh belt is squeezed, the hub friction strip directly acts on the end of the string rod At the welding point of the riveting head, it is easy to cause the welding point to be squeezed and damaged

In short, the solder joints are not strong enough and under the action of extrusion force, the existing mesh belt will break at the solder joints

Therefore, the service life is short, and the conveyor belt needs to be replaced frequently
