Non-trace sign rubber conveyor belt, production method and sign blank processing equipment

Abstract

The invention belongs to the technical field of rubber conveyor belt manufacturing, and relates to a non-marking rubber conveyor belt, a manufacturing method and a mark blank processing equipment; the non-marking rubber conveyor belt includes a base belt with a sign symbol, and the area where the sign symbol is located is Rubber compound containing coloring agent; the manufacturing method of non-marking rubber conveyor belt, the base belt blank with the mark blank is placed between two vulcanized plates, the base belt blank is pressurized, heated, and kept for a certain period of time, and the two are vulcanized Integrate into one; the processing equipment of the sign blank includes multiple dies, racks, cylinders, briquetting blocks and backing plates; the present invention generates sign symbols without traces on the surface of the conveyor belt, and the surface of the conveyor belt is worn as a whole, and the sign can always be maintained Information, users choose corresponding materials and processes when making joints or repairs, so as to ensure the quality of joints or repairs, eliminate potential safety hazards, and avoid accidents.

Description

technical field [0001] The invention belongs to the technical field of manufacturing rubber conveyor belts, and in particular relates to a non-marking rubber conveyor belt, a manufacturing method and marking blank processing equipment. Background technique [0002] The formed rubber conveyor belt blank is vulcanized on a plate vulcanizing machine. The length of the vulcanized plate is 11 meters, 21 or 41 meters. The temperature and pressure of the meter-long blank are unstable, and the vulcanization must be repeated once. [0003] Most of the rubber conveyor belts are black, and there are also blue or red. Most of them are equipped with signs. The signs are set on the bearing surface, and a few are set on the non-bearing surface. It can appear alternately on the two belt edges, and the longitudinal distance between the two signs is generally not more than 15 meters. The information in the logo includes the longitudinal full thickness tensile strength, the basic performance...

AI Technical Summary

Problems solved by technology

[0006] The sunken or embossed fonts on the conveyor belt are easily worn out and blurred, or even completely worn off, resulting in misjudgment or failure to judge the origin and structural information of the conveyor belt

[0007] If the wrong judgment leads to the use of wrong glue and glue, and the two rolls of conveyor belts with mismatched parameters are connected together, the strength of the repaired position will be weak, and the repaired position will be easily damaged, and the joint will be easily pulled. break, or even lead to catastrophic accidents, such as the sudden collapse of the conveyor belt together with the material on it, and it will hit the workers patrolling nearby, smashing the equipment next to it, etc., and the conveyor structure will be suddenly deformed or even scrapped. serious economic losses to users

[0008] If the conveyor belt whose source and structural information cannot be judged is discarded, it will cause a lot of waste and cause a lot of economic loss to the user.

[0009] A sunken or embossed font is generated on the conveyor belt, so that the rubber on the surface of the conveyor belt at this position is discontinuous, and a piece of rubber is missing, resulting in weaker tensile strength and wear resistance than other places, and irregular geometric shape. Continuous also leads to stress concentration, and it is easy to generate small cracks from here, and small cracks are easy to develop into large cracks during continuous operation, which eventually leads to the breakage of the conveyor belt

[0010] Because there is a lack of a part of the rubber material, that is, the thickness of the rubber material here is small, it is easy to expose the internal skeleton material when it is worn down, and the skeleton material is easy to be affected by moisture and water. If it is a steel wire rope core, it is easy to rust. It is a canvas core, which is easy to corrode after being exposed to moisture, and its tensile strength is also greatly reduced

[0011] Although it contains quality risks, users have no better choice, so it is still used like this
