Description

TECHNICAL FIELD

[0001] The utility model relates to super micro cotton needle felt processing equipment technical field, concretely relates to a kind of pre-pressing device for super micro cotton needle felt processing. BACKGROUND

[0002] Super micro cotton needle felt, also known as needle-punched cotton or non-woven fabric, is a kind of non-woven fabric processed by needle punching process. Its characteristics lie in that fibers are intertwined with each other through needle punching, forming a felt-like material with certain strength and density. The production process of super micro cotton needle felt mainly includes fiber opening, fiber carding, web laying, needle punching and compaction, and post-processing. Among them, needle punching and compaction is the core process. The fiber web is repeatedly punctured by the needles in the needle punching machine, so that the fibers are intertwined with each other to form a non-woven product with certain strength and density. In the post-processing step, calendering, singeing, emulsion immersion and high-temperature setting are carried out according to specific requirements to improve the performance and quality of the product.

[0003] The existing super micro cotton needle felt processing equipment does not have a pre-pressing function in use, such as the needle felt processing device disclosed in application No. CN201720646142.4. The existing cotton needle felt processing equipment does not have a pre-pressing function. Super micro cotton fibers that have not been pre-pressed may be unevenly distributed during needle punching, resulting in inconsistent density and strength of the needle felt, affecting the performance of the final product. The lack of pre-pressing step makes it difficult to accurately control the thickness of the needle felt, which may cause large fluctuations in thickness, which is not conducive to subsequent processing and use. The material that has not been pre-pressed requires more energy and time during needle punching to achieve the desired entanglement effect, resulting in reduced production efficiency. The pre-pressing process helps to preliminarily entangle and compact the fibers, improving the initial strength of the needle felt. The lack of pre-pressing step may result in insufficient strength of the needle felt, which cannot meet the use requirements. The material that has not been pre-pressed may have an uneven surface after needle punching, affecting the appearance quality of the product. Pre-pressing can also improve the filtration, thermal insulation and other properties of the material to a certain extent. The lack of pre-pressing step may result in unstable or decreased performance.

[0004] Therefore, it is necessary to invent a pre-pressing device for super micro cotton needle felt processing to solve the above problems. Utility model content
