Problems solved by technology

[0007] 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
[0008] 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, and even lead to catastrophic accidents, such as the sudden collapse of the conveyor belt and the material on it, which is lifted up instantly, hitting the workers patrolling nearby, smashing the nearby equipment, etc., and the conveyor structure will be suddenly deformed or even scrapped. serious economic losses to users
[0009] 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.
[0010] 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
[0011] 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 damp, and the tensile strength is also greatly reduced
[0012] Although it contains quality risks, users have no better choice, so it is still used like this

Embodiment

[0073] Example: see Figure 1 to Figure 14 .

[0074] A non-marking rubber conveyor belt, including a base belt 3, the base belt 3 is a black ordinary rubber conveyor belt, characterized in that the base belt 3 has a logo symbol 2, which is "ST1600" composed of six characters, and the area where the logo symbol 2 is located It is a rubber compound containing a coloring agent. 100 parts by weight of the rubber compound contains 3 parts of titanium dioxide, and the symbol 2 is displayed as white.

[0075] According to the non-trace marking rubber conveyor belt described above, this embodiment also provides a manufacturing method of the non-trace marking rubber conveyor belt, including the following steps:

[0076] 1) Evenly mix titanium dioxide into the rubber compound, and roll it into a 4 mm thick white rubber film;

[0077] 2) Die-cut the sign blank on the rolled rubber film. The sign blank that needs to be punched in this embodiment has a letter "S", a letter "T", a number...

Abstract

The invention belongs to the technical field of rubber conveying belt manufacturing, and relates to a traceless sign rubber conveying belt, a manufacturing method and sign blank processing equipment.The traceless sign rubber conveying belt comprises a base band provided with a sign symbol, and an area where the sign symbol is located is rubber materials containing a coloring agent; the manufacturing method of the traceless sign rubber conveying belt comprises the steps that a base band blank provided with the sign blank is placed between two vulcanization plates, the base band blank is pressurized and heated for a certain time, and the base band blank and the vulcanization plates are fused into a whole; and the sign blank processing equipment comprises a plurality of stamping dies, a rack, an air cylinder, a pressing block and a cushion plate. The traceless sign symbol is generated on the surface of the conveying belt, the surface of the conveying belt is wholly abraded, sign information is kept all the time, the corresponding material and technical processes are selected by a user during connecting or repairing, the connecting or repairing quality is guaranteed, potential safetyhazards are eliminated, and accidents are avoided.

Description

[0001] This application is a divisional application of the invention patent application with application number 201510529948.0. technical field [0002] 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 [0003] 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. [0004] 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 ...
