One-time double-sided frictioning calendering line

Abstract

The invention discloses a one-time double-sided rubberizing calendering line, and belongs to the technical field of rubber calendering. According to the invention, two hydraulic distance-adjusting three-roller calenders and a group of linkage devices are adopted, so that a canvas one-time double-sided frictioning process is realized, and different technological formula requirements of double-sided frictioning are met; the two hydraulic distance-adjusting three-roller calenders are adopted, after the first surface is rubberized, the process temperature is guaranteed, and the second surface is subjected to high-adhesion rubberizing when the rubberized fabric is not cooled, so that the canvas rubberizing quality is improved, and the wear resistance and the adhesive force of the belt are effectively improved; a hydraulic tension adjusting device is adopted, so that the tension of canvas between the two hydraulic distance-adjusting three-roller calenders is stable, and the frictioning quality is ensured; according to the invention, a traditional dip coating process in the triangular belt industry can be replaced, a one-time double-sided frictioning process is realized, and different process formulas are met; the problems that three adhesive tape wrapping cloth layers are high in production cost and flammable, explosive and safe in production are solved, meanwhile, the frictioning quality is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber calendering, and relates to a one-time double-sided rubber-rubbing calendering line used in the rubber calendering process. Background technique [0002] V-belt products are widely used in industry, agriculture, chemical industry, mining, automobile, machinery, construction and other industries. The V-belt is usually composed of a wrapping layer, a stretch layer, a strength layer and a compression layer. Wherein the wrapping layer is an external protective layer that integrates the stretching layer, the strength layer and the compression layer. The covering layer is composed of plain rubber canvas, which should have excellent stretchability and friction, and protect other parts from abrasion and corrosion. At present, the V-belt enterprises adopt the soaking process to produce the V-belt wrapping layer with glue. Use solvent gasoline to turn rubber into glue, apply it on cloth, and then dry it w...

Problems solved by technology

When the glue is put into the calender twice, the first few meters of the head cannot be used due to wrinkling and glue problems, resulting in waste of glue

Due to the discontinuous upper and lower gluing, the process temperature cannot be guaranteed, and the extruded products cannot meet the requirements of clear surface lines, high-strength adhesion and good wear resistance required by the outsourcing cloth process; and a single three-roll calender cannot Satisfy the user's different process formulas for wiping glue
