Feeding device for seamless air duct cloth production

Abstract

The invention relates to a feeding device for seamless air duct cloth production. The feeding device comprises a tank body, wherein a bracket is arranged on the tank body; a first clamping roller group and a first material scraping group are arranged on the bracket; a slideable clamp device is further arranged on the bracket; a second clamping roller group and a second material scraping group are arranged on the clamp device; each of the first clamping roller group and the second clamping roller group comprises at least one clamping roller; each of the first material scraping group and the second material scraping group comprises at least one scraping piece and at least one scraping rope; the end, in contact with base cloth, of the scraping piece is arranged in an inclined manner in the movement direction of the base cloth; the included angle between the scraping piece and the base cloth is smaller than 90 degrees; a liftable immersed material lifting device is arranged on the bracket; a heat conducting box used for heating slurry is arranged on the inner wall of the tank body. According to the feeding device, the uniform feeding of the seamless air duct base cloth can be realized; the distances between the two clamping roller groups and the two material scraping groups are adjustable, so that the requirement on different thicknesses of the slurry on the base cloth can be met; each material scraping group comprises the scraping piece and the scraping rope, so that the material is scraped more uniformly; the scraping piece and the scraping rope are connected with compression springs, so that the 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 feeding device 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 duct cloth ...
