[0002] Steel belt refers to a conveyor belt made of carbon steel that is used as the traction and carrying component of a belt conveyor. It can also be used to bundle goods. Steel belt is a steel material with large production volume, wide application, and many varieties. According to thickness, it is divided into thin steel belt (thickness not exceeding 4mm) and thick steel belt (thickness greater than 4mm). The thickness of the steel belt must be tested.

[0003] During the processing of steel strips, a thickness detection device is required. Thickness detection devices are divided into two types: non-contact thickness gauges and contact thickness gauges. Laser thickness gauges are a type of non-contact thickness gauge. They are generally composed of two laser displacement sensors that shoot up and down. The upper and lower sensors respectively measure the position of the upper surface and the lower surface of the object to be measured, and the thickness of the object to be measured is obtained by calculation. In the existing technology, during the processing of steel strips, dust and other particles in the factory environment are easily attached to the surface of the steel strip, or the steel strip itself is uneven, which can easily lead to inaccurate measurement of the laser thickness gauge. Therefore, a thickness detection device for steel strip processing with accurate measurement is proposed to solve the above-mentioned problems. Utility Model Content
