At this time, the connecting shaft 41 will rotate relative to the second rotating shaft 42. When it is necessary to clean the polyester adhesive residue on the inner wall of the heating kettle 1, the staff only needs to reverse the installation shaft 7. At this time, under the action of the one-way bearing 40, the connecting shaft 41 will drive the second rotating shaft 42 to rotate. Under the transmission action of the third bevel gear 44 and the fourth bevel gear 45, the reciprocating screw rod 36 will rotate to make the entire lifting seat 34 move downward along the guide rail 35.
