A textile fiber press molding device

Abstract

A textile fiber pressing forming device comprises an upper die, a lower die and an outer sleeve. The upper die comprises an upper die body and an upper die cavity. The lower die comprises a lower diebody and a lower die cavity. The upper die cavity and the lower die cavity are in up-down butt joint to form a forming cavity. The height of the outer sleeve is larger than the sum of the height of the upper / lower die. The part, around the upper die cavity, of the bottom face of the upper die body is provided with a concentric upper inner / outer sliding rail. The part, around the lower die cavity,of the top face of the lower die body is provided with a concentric lower inner / outer sliding groove. The lower inner sliding groove is in sliding fit with an upper inner sliding rail inserted in thelower inner sliding groove. The lower outer sliding groove is in sliding fit with an upper outer sliding rail inserted in the lower outer sliding groove. The upper die body is internally provided witha plurality of upper ventilation ways communicating with the upper die cavity. The lower die body is internally provided with a plurality of lower ventilation ways communicating with the lower die cavity. The outer ends of the lower ventilation ways communicate with an air outlet of an air spraying device through the air inlet area. According to the design, the shape of fiber cotton is not limited, the material utilization rate is improved, adjustability is high, and product interior uniformity can be improved.

Description

technical field [0001] The invention relates to a fiber cotton manufacturing process, which belongs to the field of textile machinery, in particular to a textile fiber pressing and forming device. Background technique [0002] At present, fiber cotton refers to a kind of shaped cotton made of various textile fibers. Textile fibers include natural fibers and chemical fibers. Most of the existing manufacturing processes are to first open the textile fibers through raw materials and card them into a net. Various processing is then carried out, such as warp and weft weaving, layer-by-layer superposition, vertical / horizontal web laying or their combination, and finally drying and cooling to obtain shaped cotton. Not only the processing process is long and the process is numerous, but also the shape of fiber cotton is greatly limited , leading to the production of follow-up products, it is necessary to carry out more shape changes to the obtained fiber cotton, such as cutting, the...

[0002] At present, fiber cotton refers to a kind of shaped cotton made of various textile fibers. Textile fibers include natural fibers and chemical fibers. Most of the existing manufacturing processes are to first open the textile fibers through raw materials and card them into a net. Various processes are then carried out, such as warp and weft weaving, layer-by-layer superposition, vertical / horizontal web laying or their combination, and finally drying and cooling to obtain shaped cotton. Not only the processing process is long and the process is numerous, but also the shape of fiber cotton is greatly limited , leading to the production of follow-up products, it is necessary to carry out more shape changes on the obtained fiber cotton, such as cutting, resulting in a large amount of waste and reducing the material utilization rate of fiber cotton
