Description

Device for improving lapping effect and lapping machine

Technical Field

The utility model relates to a non-woven mechanical equipment field especially relates to an improve lapping effect device to and a lapping machine.

Background

The lapping machine belongs to one of the main devices in the non-woven production line, the fiber web produced by the front carding machine is very thin, and the general surface density does not exceed 20g/m²And cannot be directly conveyed to the next process. Lapping is to lay layers of thin fiber webs to increase the thickness and the surface density of the fiber webs, so that the fiber webs can be reinforced in the next step.

The cross lapping machine is lapped in a reciprocating motion, and when the lapping machine reaches two ends of the lapping width and finishes reversing, the lapping trolley undergoes the changing processes of speed reduction to zero, reversing and re-acceleration. Because the speed of the carding machine for outputting the thin fiber web is constant, when the lapping trolley decelerates and stops at the two lapping ends, the thin fiber web still continues to be input, so that the thickness of the two ends of the lapped fiber web layer is increased, the weight of the fiber web layer conveyed to the next reinforcing procedure is uneven in the lapping direction, the gram weight CV value is increased, and other performances such as the thickness, the ventilation property, the strength and the like of a product are influenced. And the gram weight of the two ends is higher after needling reinforcement, so that the edge cutting is needed, and the production cost is wasted.
