Efficient grinding method for waterproof sealing strip

The invention provides an efficient grinding method for a waterproof sealing strip, and belongs to the technical field of rubber product processing. A corresponding positioning screw is selected according to the size of the waterproof sealing strip. The depth of a first guide groove in the positioning screw is required to be less than the thickness of the waterproof sealing strip. Outward pullingis conducted from the end portion of the waterproof seal strip wound around a discharge wheel. Winding is conducted on a discharge screw along a second guide groove by a plurality of rings, then penetrating into a first guide groove is conducted from one end of the positioning screw, then traction onto a winding wheel is conducted from the other end of the first guide groove, a grinding wheel abuts against the waterproof sealing strip on the middle section of the first guide groove, a driving motor, a winding motor and an air pumping motor are started, the discharge screw and the grinding wheel rotate synchronously, the positioning screw is static, the waterproof sealing strip slides in the first guide groove relative to the positioning screw at a uniform speed, and all portions of all waterproof sealing strips wound on the discharge wheel are caused to be sequentially subjected to rough grinding, fine grinding and polishing. The efficient grinding method has the advantages of being capable of continuously performing high-efficiency grinding on the single side of the waterproof sealing strips and the like.
