Description

Technical Field

[0001] The utility model belongs to the technical field of whole-core conveyor belt processing, in particular to a mold used in a belt vulcanization joint process. Background Art

[0002] The whole core flame retardant conveyor belt (hereinafter referred to as the whole core belt) is made of a whole belt core that is impregnated with polyvinyl chloride paste and plasticized or vulcanized. It has the characteristics of high strength, large transportation capacity, and balanced transportation. At the same time, the product has good flame retardant, anti-static, impact resistance, wear resistance, corrosion resistance, etc. Its performance and economic advantages have gradually increased in the conveyor belt field in recent years.

[0003] However, compared with other types of conveyor belts, the service life of whole-core belt products is shorter, mainly because once the whole-core belt is damaged, it is difficult to repair it by vulcanization. Currently, the market mostly uses belt buckles to repair broken belts. Traditional conveyor belt quick punching methods include wolf-tooth steel nails, etc., which are widely used in the field of whole-core belt connections. However, the buckle method it adopts requires a lot of manual work and special machinery, and the steps are complicated. The connection strength relying solely on the buckle cannot reach 80% of the original whole-core belt strength. The overall repair time of the whole-core belt is too long, and the downtime is long, which affects the timely production resumption of the user. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a mold for a belt vulcanization joint process to improve the efficiency of connecting the entire belt and ensure the strength of the entire belt after connection.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0022] like Figure 1 As shown, this embodiment provides a mold for a belt vulcanization joint process, including a steel plate punching mold, a joint connection cloth 1, and a riveted part; the steel plate punching mold includes an upper steel plate 2 and a lower steel plate 3, the upper steel plate 2 and the lower steel plate 3 are parallel to each other, and both ends of the upper steel plate 2 and the lower steel plate 3 are connected by a fixed plate 4; a through groove for placing the joint connection cloth 1 is formed between the upper steel plate 2, the lower steel plate 3, and the fixed plates 4 on both sides. Specifically in this embodiment, two upper steel plates 2 are connected to the upper part of the fixed plates 4 on both sides at intervals, and two lower steel plates 3 are connected to the lower part of the fixed plates 4 on both sides at intervals, and the positions of the two upper steel plates 2 and the two lower steel plates 3 correspond to each other. In this way, two sets of punching molds are formed, which can simultaneously connect the joint connection cloth 1 and the joints on both sides of the whole core belt 5.

[0023] Both ends of the joint of the whole core belt 5 are overlapped with the joint connection cloth 1 and glued to prevent displacement. In this embodiment, the joint connection cloth 1 is a high-strength aramid cloth. The joint connection cloth 1 is set through the through groove, and the overlap of the whole core belt 5 and the joint connection cloth 1 is located between the upper steel plate 2 and the lower steel plate 3. A plurality of penetration holes 6 are distributed on the upper steel plate 2.

[0024] like Figure 2 and Figure 3 As shown, the riveted part includes a hollow rivet 7 and a steel ball 8, wherein the steel ball 8 is connected to the hollow end of the hollow rivet 7, and the diameters of the hollow rivet 7 and the steel ball 8 are equal. In this embodiment, the hollow rivet 7 and the steel ball 8 are welded by a butt welding machine. A part of the steel ball 8 is located inside the hollow rivet 7, and a part is located outside the hollow rivet 7, and a slot 9 is symmetrically arranged at the hollow end of the hollow rivet 7; the riveted part is driven into the overlap of the whole belt 5 and the joint connection cloth 1 through the penetration hole 6, so that the whole belt 5 and the joint connection cloth 1 are fixedly connected.

[0025] A reinforcing plate 10 is connected between the upper parts of the two side fixing plates 4, and a reinforcing plate 10 is also connected between the lower parts of the two side fixing plates 4. The reinforcing plate 10 can make the overall structure of the steel plate punching mold more stable.

[0026] The working process of this device is:

[0027] During operation, high-strength aramid cloth is used as the connecting material of the joint of the whole core belt 5. The upper steel plate 2 and the lower steel plate 3 are located at the joint. The two ends of the joint are first bonded with the high-strength aramid cloth with glue, and the rivets are used to rivet in order according to the position of the penetration hole 6 on the steel plate mold. One end of the rivet with a steel ball 8 penetrates the high-strength aramid cloth material and the whole core belt 5 through the penetration hole 6 on the upper steel plate 2. The steel ball 8 at the head of the rivet contacts the lower steel plate 3 on the other side without a hole. The steel ball 8 hits the lower steel plate 3 to make the head of the hollow rivet 7 explode along the slot 9, thereby achieving riveting. The rivet structure used in this project is a hollow structure. A stainless steel ball is slotted and butt-welded at the rivet head. The steel ball 8 is forced to open the hollow rivet 7 to achieve rapid riveting. With high-strength aramid cloth, the whole core conveyor belt joint method is simpler and faster.
