Description

[0002] The rubber conveyor belt is a kind of transmission belt for conveying various materials, which is usually composed of a rubber layer and a skeleton material. The rubber layer is wrapped on the upper and lower surfaces of the conveyor belt, directly contacts with the materials and the external environment, and plays a role in protecting the skeleton material and conveying the materials. The rubber conveyor belt usually has properties such as wear resistance, oil resistance, acid and alkali resistance, and aging resistance. The skeleton material is the load-bearing part of the conveyor belt, which provides strength and flexibility to the conveyor belt, so that it can withstand the weight of the materials and the tension in the conveying process.

[0003] In order to ensure the quality of the rubber conveyor belt, the performance of the rubber layer needs to be detected during its manufacturing process. The traditional detection device is usually composed of two rotating rollers.

Then the rotating bidirectional screw rod 343 drives the two threaded cylinders 342, the mounting seat 341 and the friction roller 33 to move towards each other or move away from each other, so that the two friction rollers 33 can contact with the annular rubber belt supported by the movable supporting roller 13 and the fixed supporting roller 21, and apply pressure to the rubber belt to assist the detection of the rubber belt.

[0057] The reverse rotating threaded rotating rod 363 drives the second embedded block 364 to be embedded in the connecting piece 365. The starting motor 361 can drive the friction roller 33 to rotate through the connecting piece 365, the second embedded block 364 and the fixed shaft 362, so as to polish the surface of the rubber belt and test the wear resistance of each position on the rubber belt.
