Description

Technical Field

[0001] The utility model belongs to the technical field of spiral shaft cleaning, in particular to a spiral shaft cleaning mechanism. Background Art

[0002] The spiral blade is a spiral metal plate, which is usually fixed on the mandrel. The rotation of the mandrel drives the spiral blade to rotate. The rotating spiral blade can convey materials. In the fields or equipment of debris conveying and discharging, dry-wet separation, extrusion and dehydration, extruders, etc., the spiral blade is its main structure;

[0003] After the blades of the spiral shaft are welded to the shaft body, a pink colorant is needed to detect surface cracks. Conventional cleaning methods mostly use manual flushing of the spiral shaft. Because the blades of the spiral shaft are spiral-shaped and the heavy spiral shaft is not convenient for manual flipping, conventional cleaning methods are prone to cleaning dead corners, resulting in some colorant remaining on the surface of the spiral shaft;

[0004] In order to solve the above problems, a spiral shaft cleaning mechanism is proposed in the present application. Utility Model Content

[0017] In summary, the technical effects and advantages of the utility model are as follows:

[0018] 1. The spiral shaft cleaning mechanism manually winds the cable around both sides of the spiral shaft body and fixes it, then starts the second servo motor to drive the winch to rotate and retract the cable, and the spiral shaft body gradually moves up under the action of the cable, and then starts the first servo motor to drive the spiral shaft body to move horizontally through the threaded rod and the load-bearing frame.

At the same time, some excess air in the regulating box can enter the elastic airbag through the second exhaust pipe. The gradually expanding elastic airbag can further provide support for the ultrasonic cleaning machine as a whole, avoiding the overall tipping of the ultrasonic cleaning machine caused by the horizontal movement of the spiral shaft body, thereby ensuring the smooth progress of the cleaning work.
