Angle adjustable spunbond non-woven fabric production line for spinning manifold

Abstract

The invention discloses an angle adjustable spunbond non-woven fabric production line for a spinning manifold. The production line comprises a spinning assembly and a lapper, wherein the spinning assembly comprises a feeder, a screw extruder, a leftover material return device, a filter, the spinning manifold, a cold air box, a drafting device and a diffuser; the installation angle between the spinning assembly and the lapper is adjusted through an angle adjusting device, and the angle adjusting device is installed on the spinning assembly through a connecting block. According to the productionline, the width of the product can be adjusted, and the uniformity and coverage of the product can be effectively improved.

Description

Technical field [0001] The invention relates to the technical field of non-woven fabric weaving, in particular to a spunbonded non-woven fabric production line with adjustable spinning box angles. Background technique [0002] Non-woven fabric is a kind of fabric that does not need to be spun and woven. It only uses short woven fibers or filaments to be oriented or randomly arranged to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric is a new type of fiber product with soft, air-permeable and flat structure formed by directly using polymer chips, short fibers or filaments through various web forming methods and consolidation technologies. Its production process is short and production speed is fast. , High output, low cost, wide use, and multiple sources of raw materials. [0003] The two commonly used process methods in the manufacture of nonwovens are spunbond and spunlace. Although these two methods can produce ...

AI Technical Summary

Problems solved by technology

[0003] The two commonly used processes in the manufacture of nonwovens are spunbond and spunlace. Although both methods can produce nonwovens, they both have certain defects. The nonwovens produced by spunbond feel It is hard and has poor water absorption; while the nonwovens produced by spunlace method have poor strength and high cost. With the continuous development of the market, people's demand and quality requirements for nonwovens are getting higher and higher. The above two methods The produced nonwovens can no longer meet people's needs

[0004] In order to solve the above technical problems, the Chinese patent application number 201320123973.5 is a composite nonwoven fabric production line. The patent installs two fiber web production equipment and installs a cloth guide roll between the two fiber web production equipment, which is convenient for multiple The production of multi-layer nonwoven fabrics, each fiber web production equipment includes feeding hopper, extruder, screw extruder, spinning box, side blower, air drafting machine, rollers and under-wire suction fan, plus Spunlace machines, ovens and hot rolling mills can improve fabric production efficiency and fabric quality; however, due to the manufacturing process of spunlace, the nonwovens produced have certain defects, such as hard hand feeling and poor water absorption. ; and this patent only combines two sets of front-end equipment to produce non-woven fabrics. Although the production capacity has been increased, there is a disadvantage that the equipment occupies a large space
