Pneumatic supporting device for producing ultralong large caliber rubber hose

Abstract

The invention discloses a pneumatic supporting device for producing hosepipe with an overlong heavy caliber, which comprises a double-roll supporting bracket (1), an air cylinder (2), a slide grooved rail (3) and a spacing pin (4). The invention adopts the technical scheme of supporting and stabilizing a core bar by the pneumatic supporting device, and overcomes the problem and defect of low production efficiency of the prior art. The pneumatic supporting device for producing hosepipe with an overlong heavy caliber supplied by the invention utilizes the elasticity and the damping characteristic of compressed air to automatically adjust the supporting height and eliminate vibration by a double-roll support with the increased thickness of a winding adhesive layer of the core bar under the condition of given supporting force, and therefore, the production of hosepipe with an overlong heavy caliber achieves the goals of continuous operation and higher production efficiency.

Description

technical field [0001] The invention relates to a production process device of a rubber hose, in particular to a super-long-diameter rubber hose for producing super-large-diameter water-absorbing, oil-absorbing, debris-absorbing, and anti-positive and negative-pressure rubber hoses. Pneumatic support for tubes. Background technique [0002] The super long-diameter rubber hose is an engineering hose used to discharge and absorb water, oil, mud and other materials. It has the characteristics of super length, large diameter, high wear resistance, and can withstand high positive and negative pressures. It is widely used in Ports, mines, tunnels, subways, oil fields and other projects. At present, the domestic production of super long-diameter rubber hoses is still blank, and the demand mainly depends on imports. [0003] The production process of the rubber hose in the prior art is that according to the design requirements, the green rubber sheets, cords, and steel wires of di...

AI Technical Summary

Problems solved by technology

[0004] Following the production process of the rubber hose of the prior art to produce super large-diameter water-absorbing, oil-absorbing positive and negative pressure rubber hoses, the mandrel is too long to sink and bend due to gravity, and the phenomenon of "string vibration" occurs when rotating , if the double-roller support is used to lift the stable mandrel, as the thickness of the winding rubber layer increases, it must be continuously "stopped" and the lifting height of the double-roller support must be manually adjusted, resulting in continuous operation, low efficiency, and even failure to produce The problem
