Convex point pressing roller device

Abstract

The invention discloses a convex point pressing roller device. A convex point pressing roller comprises a pressing roller body and convex points, wherein the pressing roller body is of a cylinder structure, the several convex points are provided, and are evenly distributed on the outer cylindrical surface of the pressing roller body along a spiral line, the tops of all the convex points are located on the same cylindrical surface, the convex points are made through a steel and rubber composite process, and each convex point is composed of a convex point working surface and a convex point connecting portion. The convex point pressing roller device is specially used on a belt blank forming line for a ultra-wide rubber conveying belt for belt blank forming; the convex point working surfaces are made of high-strength high-hardness rubber, elastic contact is realized, and the pressure balance effect can be ensured; through the convex points, the local pressure can be concentrated and the adhesion can be enhanced, so that the local initial viscosity effect is enhanced, and the later vulcanization working procedure is facilitated; through the convex point structures additionally arrangedon the pressing roller, the stress can be dispersed, moreover, the accumulated wrinkle tendency of a cloth layer can be dispersed, then wrinkle caused by pressing is eradicated, the forming quality ofa belt blank is ensured to be stable and reliable, the product quality and the working efficiency are improved, and the rate of finished products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of conveyor belt forming equipment, in particular to a convex point pressing roller device. Background technique [0002] At present, the traditional pressure roller device is mainly used in the blank forming equipment of the ultra-wide rubber conveyor belt. Specifically, during the forming process of the ultra-wide rubber conveyor belt, the upper and lower layers of cloth are pressed together by the pressure roller. The deficiencies are: [0003] The traditional press roller is a smooth cylindrical structure, and there is no convex point on the outer circle of the press roller, so the pressure is dispersed when the cloth layers are pressed together, thereby reducing the initial tack and bonding strength, which is not conducive to the later vulcanization process. [0004] During the pressing process, cloth folds are gradually accumulated, and the cloth layer is pressed out into wrinkles, which leads to a ...
