Description

Joint structure of aramid fiber conveyer belt

Technical Field

The utility model belongs to the technical field of the conveyer belt joint technique and specifically relates to a joint design of aramid fiber conveyer belt.

Background

In the prior art, most joints of a rubber conveying belt are laminated at the joints through belt cores, core rubber is attached to the joints, and surface rubber is vulcanized to form an integral structure. However, the connection fastness and the like of the mode are relatively poor, and the conditions such as breakage and the like are easy to occur in the using process; and the rubber material at the joint is easy to wear in the using process, and the service life of the conveying belt is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a joint design of aramid fiber conveyer belt, the structure of its joint does not change the original structure of conveyer belt, and the intensity of joint is high and the long service life of conveyer belt.

In order to achieve the purpose, the utility model relates to a joint structure of an aramid fiber conveying belt, which comprises an aramid fiber belt core, core rubber layers arranged at two sides of the aramid fiber belt core and a surface rubber layer arranged at the outermost side, wherein connecting fingers in the length direction are formed after the two ends of the aramid fiber belt core are cut, the connecting fingers at the two ends of the aramid fiber belt core are mutually staggered, a belt core connecting area is formed after matching and connecting, the core rubber connecting layers are arranged at two sides of the belt core connecting area, and the surface rubber connecting layers are respectively arranged at the outer parts of the core rubber connecting layers; the length that the tie layer was glued to the core is greater than the length of taking the core joining region, and the length that the tie layer was glued to the face is greater than the length that the tie layer was glued to the core, just take the core joining region to be located the core and glue the tie layer within range, the tie layer is glued to the core is located the tie layer within range.

Above-mentioned technical scheme, the aramid fiber area core that will connect the department adopts the form that the connection indicates crisscross butt joint to connect, can not produce the condition of range upon range of for aramid fiber area core is in the department of connecting also last smooth state, and is unanimous with the structure that the conveyer belt was originally, laminates the core again and glues the tie layer and knead dough and glue the tie layer and carry out the vulcanization, and bulk strength is high, and aramid fiber area core connects smoothly in the use, levels, can not cause the sizing material wearing and tearing of joint department, has promoted the life of conveyer belt. In addition, when the conveying belt passes through the roller, the inner belt core cannot be extruded to influence the performance of the conveying belt.

Two connecting fingers positioned at the outermost side of the matched belt core connecting area are right-angled triangles, and the rest connecting fingers are isosceles triangles. The design of this structure can make area of contact between the connection finger big, and joint strength, fastness are high, and the cooperation is more reliable and more stable moreover.

The length of the connecting finger is 500-3000mm, the width of the connecting finger is 40-85mm, the length of the core glue connecting layer is 750-3450mm, and the length of the surface glue connecting layer is 800-3500 mm.

The utility model provides a joint design of aramid fiber conveyer belt can make the aramid fiber tape core joint department not change the original structure of conveyer belt, and joint department firm in connection, intensity are high moreover, long service life etc..
