Lapping machine provided with high-speed rolling type bracket mechanism and applied to bio-based spun-bonding and hot-rolling line

Abstract

The invention relates to the technical field of non-woven fabric manufacturing equipment, in particular to a lapping machine provided with a high-speed rolling type bracket mechanism and applied to a bio-based spun-bonding and hot-rolling line. The lapping machine comprises a lapping machine rack, a web curtain, a drive roller, a fabric guide roller, a pre-roller, a rubber lower support roller and an air suction bellows, wherein a horizontal rolling mechanism is arranged above a grating of the air suction bellows and comprises a bearing, a bearing block and a roller rod. During high-speed operation of the web curtain, the friction is reduced, the operation resistance is reduced, energy and power are saved, and the service life of the web curtain is prolonged; the operation stability of the web curtain is improved, the produced non-woven fabric product is stable in quality, the fabric surface is uniform and free of ripples, and uniformity of a fiber web is good.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric manufacturing equipment, in particular to a web-laying machine with a high-speed rolling bracket mechanism for a bio-based spun-bonded hot rolling production line. Background technique [0002] The web laying machine is a commonly used non-woven web laying mechanism for spunbond needle punching, spunlace, and hot rolling production lines. For spunbond needle punching production equipment, the general laying line speed is within 5-20 m / min. For spunbond spunlace production equipment, the laying line speed is in the range of 10-50 m / min. The grammage of the spunbond needling production line equipment is 80-600g / m 2 , the width is 2400-6800mm. Spunbond spunlace production line equipment product weight is 50-220g / m 2 , the width is generally 1600-2400mm. The net curtain of the netting machine is generally made of polyester monofilament material, and the polyester dry net is woven, and the...

Problems solved by technology

In the internal construction of the net-laying machine, except for the main drive roller, fabric guide roller, deviation-correcting roller, and web roller, which support the net curtain, the rest of the parts are all suspended in the air, so that the high-speed running net curtain is dragged due to the down suction. Due to the effect of the wind, the mesh curtain has serious friction with the lower suction grid, which causes the antistatic mesh curtain to often rub and fluff and affect the service life
