Description

Technical Field

[0002] The main shaft of a tanning machine usually refers to the main rotating shaft of key equipment in tanning equipment, such as a drum. It is one of the most important moving parts in the equipment. The main shaft is the key component that drives the drum body to rotate. In a leather cutting machine, the main shaft may drive the cutting mechanism to reciprocate up and down through a transmission device to achieve the cutting of leather. When the main shaft of a tanning machine is manufactured, it is necessary to use a flaw detector to inspect the main shaft of the tanning machine. Usually, an ultrasonic flaw detector is used to perform flaw detection on the main shaft of the tanning machine.

[0003] During the flaw detection process, the existing ultrasonic flaw detector needs to use a coupling agent to ensure good contact between the ultrasonic probe and the main shaft. The existing ultrasonic flaw detector is mainly performed manually, and it is impossible to evenly apply the coupling agent on the main shaft body of the tanning machine, so that the ultrasonic flaw detector cannot accurately receive and analyze the defect signal inside the main shaft, which affects the efficiency and accuracy of the detection and leads to low production efficiency of the main shaft of the tanning machine. At the same time, the existing ultrasonic flaw detector cannot clean the coupling agent on the surface of the main shaft of the tanning machine after flaw detection, which increases the demand for manual maintenance.
