Method for simultaneously polishing two surfaces of waterproof sealing strip

Abstract

The invention provides a method for simultaneously polishing two surfaces of a waterproof sealing strip and belongs to the technical field of rubber product processing. Proper positioning screws are rotated according to the size of the waterproof sealing strip, and the depth of a guide groove in each positioning screw is smaller than the thickness of the waterproof sealing strip; the positioning screws, a winding wheel and a discharging wheel are mounted, and then the waterproof sealing strip is pulled out from the end part of the waterproof sealing strip wound on the discharging wheel and iswound around the guide groove of one positioning screw from bottom to top; the waterproof sealing strip is wound to the upper end of the corresponding positioning screw along the guide groove; then, the waterproof sealing strip penetrates through a guide wheel and is wound around the guide groove in one positioning screw from top to bottom; the waterproof sealing strip is wound to the lower end ofthe corresponding positioning screw along the guide groove and then connected with the winding wheel; a driving motor is started to enable a grinding wheel and the winding wheel to rotate synchronously; and the two opposite side faces of the waterproof sealing strip are ground at the same time through the grinding wheel at a time. The method has the advantages that the two faces of the waterproofsealing strip can be ground at the same time.

Description

technical field [0001] The invention belongs to the technical field of rubber product processing, and relates to a method for simultaneously grinding two surfaces of a waterproof sealing strip. Background technique [0002] In the chemical industry, electric power, steel, metallurgy, water treatment and other industries, the application of sealing strips is largely involved in operating equipment and storage tanks, especially the lining gasket of vulcanized rubber for waterproof and anti-corrosion functions. [0003] Due to the soft quality and narrow size of the rubber strip, continuous grinding is often done manually. However, as a waterproof and anti-corrosion gasket, the flatness of the mating surface is extremely high, which directly affects its waterproof and sealing performance. The existing There are problems in the clamping and tensioning of the sealing strip in the grinding method. Because the sealing strip is narrow, the grinding force surface is extremely small, ...

AI Technical Summary

Problems solved by technology

[0003] Due to the soft quality and narrow size of the rubber strip, continuous grinding is often done manually. However, as a waterproof and anti-corrosion gasket, the flatness of the mating surface is extremely high, which directly affects its waterproof and sealing performance. The existing There are problems in the clamping and tensioning of the sealing strip in the grinding method. Due to the narrow sealing strip, the grinding force surface is extremely small, so the grinding efficiency is very low, and it is difficult to guarantee the flatness

[0004] In some cases, both sides of the waterproof sealing strip need to be pressed against the flat surface of the equipment to achieve the sealing between the two sides of the sealing strip and the equipment. The existing methods cannot realize the simultaneous grinding of both sides of the sealing strip
