Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a tear-resistant steel wire rope core conveyor belt. Background Art

[0002] The conveyor belt is an essential part of the conveyor, and different types of conveyors often use different structures of conveyor belts. Generally speaking, when the conveyor has high power and the goods transported by the conveyor are heavy, a conveyor belt with a steel wire rope core is often used to ensure that the conveyor belt will not break easily.

[0003] For example, a Chinese patent with patent number CN202022990832.6 discloses a tear-resistant steel wire rope core conveyor belt, comprising a steel wire rope body, a core rubber is fixedly connected to the surface of the steel wire rope body, a first protective layer is fixedly connected to the top of the core rubber, a second protective layer is fixedly connected to the bottom of the core rubber, the first protective layer comprises a first reinforcement layer, and a first anti-corrosion layer is fixedly connected to the top of the first reinforcement layer. This tear-resistant steel wire rope core conveyor belt solves the problem of poor strength of existing steel wire rope core conveyor belts through the coordinated use of steel wire rope body, core rubber, first protective layer, second protective layer, first reinforcement layer, first anti-corrosion layer, high temperature resistant layer, wear-resistant layer, second reinforcement layer, second anti-corrosion layer and covering layer. When the conveyor belt encounters a harsh working environment such as the belt surface being impacted by large pieces of material or pierced by sharp materials, surface damage or longitudinal tearing often occurs, and the entire conveyor belt is immediately scrapped, reducing its service life.

[0004] Although the tear-resistant steel wire rope core conveyor belt provided by the above patent has high strength and is not easy to break, the steel wire rope is arranged along the longitudinal direction of the conveyor belt, and there is no reinforcement structure in the transverse direction of the conveyor belt. This makes the transverse edge of the conveyor belt easy to tear. Although the steel wire rope structure prevents the entire conveyor belt from breaking, the tearing of the edges on both sides of the conveyor belt can easily cause the goods to leak from both sides of the conveyor belt when the conveyor belt is transporting goods. Utility Model Content

[0008] Preferably, a first canvas layer is provided in the middle of the outer covering layer, and first reinforced rubber layers are provided on the top and bottom of the first canvas layer, and two layers of the first reinforced rubber layers sandwich the first canvas layer and are pressed together.

[0009] Preferably, a wear-resistant rubber layer is provided on the top surface of the outer covering layer, and an outer surface of the wear-resistant rubber layer is provided with anti-slip textures.

[0012] Preferably, the inner surface of the frosted rubber layer on the bottom surface of the inner covering layer is uniformly provided with grooves, and the grooves are used to increase the friction between the inner covering layer and the conveyor driving component.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. A belt core layer is sandwiched between the inner covering layer and the outer covering layer of the utility model. A plurality of steel ropes are evenly arranged inside the belt core layer from left to right. The steel ropes are wrapped by the wrapping rubber layer.
