Device for simultaneously polishing double surfaces of waterproof sealing strip

Abstract

The invention provides a device for simultaneously polishing double surfaces of a waterproof sealing strip, and belongs to the technical field of rubber product machining equipment. The device comprises a machine base, a polishing wheel, two positioning screws, a winding wheel and a discharging wheel, wherein the axis of each positioning screw is parallel to the axis of a polishing screw; the positioning screws are provided with spiral guide grooves matched with the width of the waterproof sealing strip; the two positioning screws are symmetrically arranged on the outer side of the polishing wheel; the waterproof sealing strip is drawn between the discharging wheel and the winding wheel; after the waterproof sealing strip is pulled out by the discharging wheel, the waterproof sealing stripis wound to the upper end from the lower end of one positioning screw, then the waterproof sealing strip is wound to the lower end from the upper end of the other positioning screw; the spiral directions of the guide grooves in the two positioning screws are the same; the two opposite surfaces to be polished of the waterproof sealing strip are guided by the two positioning screws and then both abut against the polishing wheel; and the winding wheel is connected with the polishing wheel through a speed reduction mechanism. The device for simultaneously polishing the double surfaces of the waterproof sealing strip has the advantages of simultaneously polishing the two surfaces of the waterproof sealing strip.

Description

technical field [0001] The invention belongs to the technical field of rubber product processing equipment, and relates to a double-sided simultaneous grinding device for waterproof sealing strips. 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 sma...

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
