Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] refer to figure 1 and figure 2 As shown, the jointless endless conveyor belt in this embodiment includes an annular upper cover rubber layer 1, a lower cover rubber layer 2 and an intermediate skeleton layer 3, and the upper cover rubber layer 1, the lower cover rubber layer 2 and the middle skeleton layer 3 are vulcanized as In one piece, the middle skeleton layer 3 is a thread wound helically on the lower covering rubber layer 2 .
[0021] When the wire rope is wound in a spiral, the pitch P is 1-5mm, which depends on the specific use requirements of the endless conveyor belt. The smaller the pitch, the denser the wire rope winding and the greater the strength.
[0022] The wire rope material can be chemical fiber or steel wire rope. When it is chemical fiber, nylon, polyester or aramid fiber can be selected, and the strength is high, so as to ens...

The invention provides a jointless annular conveying belt and a preparation method thereof, and can solve the problems that the joint of the conventional annular conveying belt has low strength and the whole strength of the annular belt is influenced. The jointless annular conveying belt comprises an annular upper covering adhesive layer, an annular lower covering adhesive layer and an annular middle skeleton layer, wherein the upper covering adhesive layer, the lower covering adhesive layer and the middle skeleton layer are vulcanized into a whole; the middle skeleton layer is a rope which is spirally wound on the lower covering adhesive layer. The jointless annular conveying belt provided by the invention directly forms an annular structure after being formed; raw adhesive joints before vulcanization exist only when the upper covering adhesive layer and the lower covering adhesive layer are formed; the middle skeleton layer has no joint; the respective joints of the upper covering adhesive layer and the lower covering adhesive layer are crosslinked into a whole through chemical reaction when being vulcanized, heated and crosslinked, so that the whole annular conveying belt has no joint, the whole strength of the conveying belt is consistent and the strong force is greatly enhanced.
Description
technical field [0001] The invention relates to an endless conveyor belt, in particular to a jointless endless conveyor belt and a preparation method thereof. Background technique [0002] The existing endless conveyor belts (abbreviated as endless belts) are all strips formed into a ring through end joints. The strips are usually wound on rollers, about 200m / roll, and the length of the endless belt is cut according to the required circumference. Take strips of corresponding length, and then carry out splicing processing to form an endless conveyor belt. The joining of the joints usually adopts mechanical joints, cold glue joints, vulcanized joints, etc., and the skeleton layer of the conveyor belt is mainly a steel wire rope skeleton layer. The skeleton layer at the joint cannot be glued, so the strength of the joint is only the strength of the skeleton layer. 70%-80% of that will greatly reduce the overall strength of the annular belt.
