Cylindrical shell and mandrel adopt metallic material to manufacture, and elastic ring adopts rubber or spring to manufacture.When elastic ring is manufactured with rubber, can adopt sulfuration casting glue fixed between cylindrical shell and mandrel and the elastic ring; Also can between cylindrical shell mandrel and elastic ring, connect with the mutual embedding of corresponding noncircular cross section.When elastic ring was spring, the draw-in groove clamping was adopted at cylindrical shell and mandrel and elastic ring two ends.

The later-model advantage of this reality is: 1, good damping effect.Shock reducing structure changed originally draw, the compressive strain mode, with torsional deflection damping, shock-absorbing, and torsional deflection is with cylindrical shell cross section outside dimension amplitude of deformation may command in the reasonable scope, makes damping effect reach best.Because reversing with shock reducing structure, knife rest and scraper move simultaneously along tape surface, overcome originally draw, compressive strain causes the knife rest shake and the scraper that produces flicks and the butt phenomenon tape surface, make scraper and tape surface adhesive ability even, good stability, the shake little, the cleaning effect increases, and can adapt to the higher mass transport occasion of belt speed.

2, long service life.Shock reducing structure upper shell and elastic ring are fixed or embedding connects the intensity height, torsion is evenly distributed, and can stress concentration not take place and tear or twist off the phenomenon of elastic ring, and doctor edge sheet aseismicity improves in addition, and the utility model is prolonged service life, and maintenance, repair are easy.

3, fabrication and installation are convenient, and cost is low.The utility model basic structure is identical with original shock reducing structure with mounting means, is convenient on original scrape type swabbing pig, change and change, and simple in structure, making and easy for installation, cost reduces.
