Problems solved by technology

[0002] The endless conveyor belt is the main type of conveyor belt. Most of the endless conveyor belts are made by connecting the conveyor belts with ends by joints. Although there are some one-time formed endless conveyor belts, a large number of conveyor belts are non- standard products, the existing standardized production of endless conveyor belts cannot meet the needs, and for a long period of time in the future, the use of joints to produce endless conveyor belts will still be the main method
[0003] The joint mode of the existing conveyor belt mainly adopts interlayer bonding, vulcanized joint or metal joint. The interlayer bonding is carried out for the multi-layer fabric core belt. Peel it off, and then glue the two ends together. The vulcanization method is mainly used for rubber conveyor belts. Metal joints are widely used. These joint methods have their own advantages and disadvantages. Among them, the surface of the interlayer bonding and metal joint methods There are certain protrusions, the surface of the conveyor belt is not smooth, the vulcanization method can make the surface of the conveyor belt smooth, but the operation time is long and the process is complicated, and it is only suitable for rubber conveyor belts
[0004] For the uneven surface of the joint, the current method is to cut with a knife or grind with tools such as sandpaper and grinding wheels. This method can make the surface of the joint smooth, but the operation is more troublesome, and it is easy to damage the conveyor belt. Cause secondary damage and reduce the strength of the conveyor belt to a certain extent

Embodiment 1

[0027] The conveyor belt in this embodiment has a one-cloth-one-glue structure, wherein the glue layer is polyvinyl chloride, and when the conveyor belt is connected, the steps are as follows:

[0028] Punching, the first connecting end 10 of the conveyor belt is cut out a plurality of first convex teeth 11 arranged in a zigzag shape, and the second joint end 20 is cut out a plurality of second convex teeth 21 arranged in a zigzag shape. The tooth top of the tooth 11 corresponds to the tooth groove of the second convex tooth 21 , and the tooth groove of the first convex tooth 11 corresponds to the tooth top of the second convex tooth 21 .

[0029] In this embodiment, the first protruding teeth 11 and the second protruding teeth 21 are both triangular in shape.

[0030] Pre-connection, the first connection end and the second connection end are abutted, so that the first convex tooth and the second convex tooth are engaged with each other, and then the connection between the fir...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, the difference is that:

[0035] When the upper heating plate and the lower heating plate pressurize the junction of the first protruding tooth and the second protruding tooth, the pressure is 0.3 MPa.

[0036] When heating the upper heating plate and the lower heating plate, the temperature was 180° C., and the temperature was lowered after heating for 25 minutes.

Embodiment 3

[0038] The conveyor belt in this embodiment has a two-cloth-two-glue structure, and the glue layer is polyvinyl chloride. When the conveyor belt is jointed, proceed as follows:

[0039] The first connection end 30 of the conveyor belt is stripped into two layers along the length direction of the conveyor belt, and each layer includes a cloth and a glue. For the convenience of description, the two layers of the first connection end 30 are respectively called For the first layer A31 and the second layer A32, the first layer A31 and the second layer A32 are respectively punched, the first protruding teeth 33 of the first layer A31 are arranged in a zigzag shape, and the second layer A31 The first protruding teeth 34 of A32 are arranged in a zigzag shape. There is a first distance L1 between the first protruding teeth 33 of the first layer A31 and the first protruding teeth 34 of the second layer A32 along the length direction of the conveyor belt.

[0040]Then the second connect...

Abstract

The invention discloses a seamless splicing method for a conveying belt. The seamless splicing method for the conveying belt comprises the following steps: (1) tooth forming: cutting a first connecting end of a conveying belt to be spliced to form a plurality of first convex teeth which are arrayed to be in the shape of saw teeth, and cutting a second connecting end to form a plurality of second convex teeth which are arrayed to be in the shape of saw teeth; (2) pre-connection: combining the first convex teeth with the second convex teeth together in a clamping manner, and then adhering the first convex teeth to the second convex teeth in a baking manner through hot air; and (3) pressurizing and heating positions where the first convex teeth are connected with the second convex teeth by an upper heating plate and a lower heating plate so that the positions where the first convex teeth are connected with the second convex teeth are melted and are integrated with each other, and finally, cooling to solidify melted parts of the connection positions so as to finish connection between the first connecting end and the second connecting end. The seamless splicing method for the conveying belt is suitable for the conveying belt of which the surface is smooth and the tensile strength is in a range of 80-200 N / mm. After the conveying belt is spliced by the method, the surface of the conveying belt is smooth. The seamless splicing method is particularly suitable for conveying belts of which rubber layers are made of materials such as polyvinyl chloride and polyurethane.
