Air flow carding and lapping integrated machine

Abstract

The present invention discloses an air flow carding and lapping integrated machine, and belongs to the field of fiber re-processing equipment. The machine comprises a discharging assembly, a carding assembly and a needling machine which are arranged in a pipeline way, wherein the input end of the discharging assembly is provided with a condenser, the output end of the discharging assembly corresponds to the input end of the carding assembly, the output end of the carding assembly corresponds to the input end of the needling machine, the carding assembly comprises a roller, a cylinder roller, ametal grid baffle roller and a dust cage which a material sequentially passes through, a negative pressure adsorption machine is arranged in the dust cage, the negative pressure is formed in the dustcage to adsorb the material conveyed by the dust cage, an outer circle of the dust cage is provided with a metal grid conveying belt used for conveying the material, and the material passes through the metal grid conveying belt and then enters the needling machine through a discharging conveying belt. Short fibers, long fibers and mixed fibers can be subjected to product manufacturing, the production efficiency is high, the unit square gram weight error is small, the automation degree is high, treatment and recycling of leftovers are realized, the environment is protected, and the economic benefits of enterprises are improved.

Description

Technical field [0001] The invention belongs to the field of environmental protection equipment, relates to the reuse of fiber waste, and particularly relates to an air-flow carding and netting integrated machine, which mainly processes leftover materials of automobile interior decoration parts. Background technique [0002] Under the pressure and form of the country's increased efforts to control the environment and low-carbon and environmentally friendly production, automotive interior materials produce a large amount of waste scraps during the production process and cannot be processed. Our company is an enterprise that produces automotive interior parts, and generates waste scraps every day More than 2 tons, it cannot be handled and there are hidden safety hazards. [0003] The car interior parts are composed of polypropylene fiber and hemp fiber that are synthesized through high temperature and high pressure molding. The remaining leftover materials in the same industry are pr...

Problems solved by technology

[0002] Under the pressure and form of the country's increased efforts to control the environment and low-carbon and environmentally friendly production, a large amount of waste scraps are produced in the production process of automotive interior materials and cannot be processed. Our company is an enterprise that produces automotive interior parts, and waste scraps are generated every day. More than 2 tons, it cannot be handled and there are safety hazards

[0003] The components of automotive interior parts are polypropylene and hemp fibers, which are formed by high temperature and high pressure. The remaining scraps in the same industry have been processed in different ways, but none of them have achieved satisfactory results. The length is basically destroyed, the fiber is too short, and it also contains granular blocks of different sizes, so that the existing equipment cannot solve the above problems. At present, domestic carding machines can only use long fibers, and a single airflow machine can only To deal with short fibers, a single carding machine and air machine cannot satisfy the mixed laying of long and short fibers. The traditional equipment is a single material with good effect, but the mixed material cannot achieve the expected effect. The carding machine can only use long fibers. , the surface of the air-laid net is long fibers, and the inside is full of small pieces and slag, that is, the face of yin and yang, and the quality cannot be guaranteed
