Problems solved by technology

[0002] In the prior art, since there are triangular areas at both ends of the flexible conveyor belt, and the thickness of the rubber material in the triangular area is greater than that of the base belt area, and a canvas core is arranged inside the base belt; Too much rubber in the triangular area will cause the rubber in the triangular area to squeeze the base belt during the vulcanization process. The base belt and the triangular area are vulcanized at the same time, so the base belt will be deformed during the extrusion process, resulting in the inner canvas core. Wrinkles, compression, etc. will affect the stability of the conveyor belt; in addition, if the rubber material in the triangle area is placed too little, it will cause a sponge structure after vulcanization in the triangle area, and there will be gaps in the interior, which will affect the normal use of the conveyor belt
At the same time, due to the large length of the triangular area, it is impossible to ensure that the amount of rubber in each part can just match the amount of rubber in the triangular area during the process of adding rubber, so the current technology is difficult to solve the above problems

Embodiment 1

[0017] The manufacturing method of a kind of flexible conveyor belt described in this embodiment, concrete steps are as follows:

[0018] Through mastication and mixing, the rubber material is obtained and made into a base belt, and a canvas core is arranged inside the base belt, and cold-pressed;

[0019] Rubber ingredients in the triangle area: natural rubber, butadiene rubber, styrene-butadiene rubber, carbon black, oil, anti-aging agent, accelerator;

[0020] Triangular area rubber is obtained by mastication and mixing;

[0021] Separate vulcanization, first press the base belt and then vulcanize; then polish the base belt within a range of 15cm wide on both sides of the edge, and perform one-time vulcanization after the base belt is docked with the rubber in the triangle area;

[0022] Complete the manufacture of flexible conveyor belts.

Embodiment 2

[0024] Such as figure 1 As shown, the manufacturing method of a flexible conveyor belt described in this embodiment, the specific steps are as follows:

[0025] Through mastication and mixing, the rubber material is obtained and made into a base belt, and a canvas core is arranged inside the base belt, and cold-pressed;

[0026] Rubber ingredients in the triangle area: natural rubber, butadiene rubber, styrene-butadiene rubber, carbon black, oil, anti-aging agent, accelerator;

[0027] Triangular area rubber is obtained by mastication and mixing;

[0028] Separate vulcanization, vulcanize the rubber material in the triangular area first, and control the temperature at 148°C for 50 minutes. When the rubber material in the triangular area is vulcanized, use mold 2 to heat the surface of the triangular area that is not connected to the base belt. The connected surface is provided with a cooling plate 1, and the cooling plate 1 is a hollow structure 3, and cooling water is inter...

Embodiment 3

[0031] The manufacturing method of a kind of flexible conveyor belt described in this embodiment, concrete steps are as follows:

[0032] Through mastication and mixing, the rubber material is obtained and made into a base belt, and a canvas core is arranged inside the base belt, and cold-pressed;

[0033] Rubber ingredients in the triangle area: natural rubber, butadiene rubber, styrene-butadiene rubber, carbon black, oil, anti-aging agent, accelerator;

[0034] Triangular area rubber is obtained by mastication and mixing;

[0035] One-time vulcanization: The triangular area rubber is formed by cold pressing with a mold and attached to the surface of the base belt, so the canvas core inside the base belt can be kept flat during the cold pressing process, and then the base belt and the triangular area rubber are processed inside the vulcanizing machine. one-time vulcanization;

[0036] Complete the manufacture of flexible conveyor belts.

Abstract

The invention relates to the technical field of rubber conveying belts, in particular to a manufacturing method of a flexible conveying belt. The manufacturing method comprises the following specificsteps of obtaining a rubber material through plastifying and mixing so as to prepare a base belt, arranging a canvas core inside the base belt, and performing cold pressing molding; carrying out batching of a triangular area rubber material; obtaining the triangular area rubber material through plastifying and mixing; carrying out split vulcanization, firstly pressing the base belt and then vulcanizing; then grinding in a range of 15 cm wide on the two sides of the base belt, and performing one-time vulcanization after butting the base belt and the triangular area rubber material; and completing the manufacturing of the flexible conveying belt. According to the manufacturing method of the flexible conveying belt, through reasonable procedures and the design of the formula, the modulus of the triangular area rubber material of the flexible conveying belt can be effectively improved, and meanwhile, in a forming vulcanization process, the situation that a sponge structure is generated dueto too little triangular area rubber material, or extrusion is generated due to the too much rubber material, so that wrinkles of the canvas core inside the base belt is generated can be avoided, andthe quality of the conveying belt is improved.
