The application time is long, and there are also problems such as uneven manual application and the thread application length not meeting the requirements. Bolt application personnel need to brush the bolts repeatedly for a long time when applying, which is prone to fatigue. At the same time, the uneven application of solid lubricating paste and insufficient application length will cause quality problems. Therefore, it is necessary to design a bolt solid lubricating paste application device. The device proposed in this patent uses PLC to control the cylinder drive, and cooperates with the motor to drive the brush barrel to rotate to complete the solid lubricating paste brushing. It improves production efficiency, reduces labor intensity, and improves product quality. Summary of the invention
