Non-woven fabric lapping machine air supply mechanism

Abstract

The invention discloses a non-woven fabric lapping machine air supply mechanism comprising a lapping machine curtain net; an air suction path is arranged below the lapping machine curtain net, and an air inlet path is arranged above the curtain net; the air suction path is connected with an air suction fan; an air suction fan pipe is connected with an air-conditioning processing chamber; an air-conditioning processing chamber pipe is connected with an air inlet pipe; the end of the air inlet pipe is provided with a plurality of branch air inlet tubes; air outlets of the branch air inlet tubes respectively face the lapping machine curtain net, and are respectively provided with an air uniform plate; a control valve is respectively arranged on each branch air inlet tube. Compared with the prior art, multi-air paths are employed to match with air uniform plates of different air outlet angles, and the machine can be opened and closed at any time according to production needs, thus improving net uniformity and intensity; the air uniform plates are prepared by honeycomb bore plates and ventilation plates of different bore density, so air force can be divided to form even air supply, and thus improving final production quality.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric manufacturing technology equipment, and in particular relates to an air supply mechanism of a non-woven fabric laminating machine. Background technique [0002] At present, in the process of producing polyester spunbonded hot-rolled non-woven fabrics, it is necessary for the suction channel to absorb the wind above the net curtain to firmly suck the fiber net on the net curtain, so that the fiber net can be evenly sewed on the net curtain without forming a flipped net. , which requires that the size of the air supply is appropriate, and the distribution must be uniform. Otherwise, it will easily lead to more fibers in places where the suction is large, and less fibers in places where the suction is small, resulting in serious uneven laying and affecting product quality; at the same time, the current air delivery The wind mechanism all adopts straight air ducts, which is not conducive to a...

[0002] At present, in the process of producing polyester spunbonded hot-rolled non-woven fabrics, it is necessary for the suction channel to absorb the wind above the net curtain to firmly suck the fiber net on the net curtain, so that the fiber net can be evenly sewed on the net curtain without forming a flipped net. , which requires that the size of the air supply is appropriate and the distribution must be uniform. Otherwise, it will easily lead to more fibers in places with strong air suction, and less fibers in places with small suction, resulting in serious uneven laying and affecting product quality; at the same time, the current air delivery The wind mechanism adopts straight air duct, which is not conducive to adjusting the wind direction, so that the final formed net is uneven and the strength is not high
