Feeding system for production of seamless air duct cloth

Abstract

The invention relates to a feeding system for production of seamless air duct cloth. The feeding system comprises a tank body, wherein a bracket is arranged on the tank body; a clamping roller group I and a scraping blade group I are arranged on the bracket; a slidable clamp device is further arranged on the bracket; a clamping roller group II and a scraping blade group II are arranged on the clamp device; each of the clamping roller group I and the clamping roller group II comprises at least one clamping roller; each of the scraping blade group I and the scraping blade group II comprises at least one scraping blade; the end, in contact with base cloth, of each scraping blade is inclined in the moving direction of the base cloth; the included angle between each scraping blade and the base cloth is smaller than 90 degrees; a liftable prepreg lifting device is arranged on the bracket; a heat conduction box for heating a sizing agent is arranged on the inner wall of the tank body. The feeding system can uniformly feed the seamless air duct cloth, can adjust the interval between two clamping roller groups as well as between the two scraping blade groups, is reliable in scraping, can meet the requirement for different thicknesses of the sizing agent fed on the base cloth and improves the production efficiency; the scraping blades are connected with compression springs, so that damage to the base cloth can be reduced.

Description

technical field [0001] The invention relates to a fan cloth production device, in particular to a material feeding system for the production of seamless fan 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 seam du...
