Feeding device for seamless ventilation ducting fabric production

Abstract

The invention relates to a feeding device for seamless ventilation ducting fabric production. The feeding device comprises a concave tank body, wherein a bracket is arranged on the tank body; a clamping roll group I and a scraper group I are arranged on the bracket; a slidable clamp device is further arranged on the bracket; a clamping roll group II and a scraper group II are arranged on the clamp device; base cloth can pass through a gap between the clamping roll group I and the clamping roll group II and a gap between the scraper group I and the scraper group II; each of the clamping roll group I and the clamping roll group II comprises at least one clamping roll; each of the scraper group I and the scraper group II comprises at least one scraper which adopts a steel wire; a soaking and lifting device capable of lifting relative to the tank body is arranged on the bracket; and a heat conduction box for heating size is arranged on the inner wall of the tank body. The feeding device can perform uniform feeding on seamless ventilation ducting fabric, the gap between the two clamping roll groups and the gap between the two scraper groups are adjustable, so that the requirement for different thicknesses of the size on the base cloth can be met, and the production efficiency is improved; and the scrapers adopt the steel wires, accordingly, the cost is lower, and the replacement is convenient.

Description

technical field [0001] The invention relates to a production device for air tube cloth, in particular to a feeding device for the production of seamless air tube cloth. Background technique [0002] Most of the existing seamed air tube fabrics for mining use flat cloth, which must be connected into a cylinder through hot air welding or high frequency welding or sewing tie wires, and there are mechanical defects in the stressed structure; so at present, the seamed air tube Cloth is gradually replaced by seamless air duct cloth, which is coated on a cylindrical base cloth (a round cylindrical film inside the base cloth) made of high-strength and high-modulus polyester fibers woven with high density. PVC material is made after high-temperature plasticization, which has the advantages of high strength, high wear resistance, folding resistance and long service life. The seamless air duct cloth is to set the inner film in the base cloth and then load the material. The existing se...
