Control system and method for uniformity of nonwoven fabric

Abstract

The invention relates to a control system and method for the uniformity of a nonwoven fabric. The control system is located below a slit drafter, mainly compensates for the uneven transverse arrangement of slit type draft fibers, and comprises a channel and an air suction device, wherein the side wall of the channel is provided with air supply holes, the air suction device is located at a discharging end of the channel, the side wall of the channel is slidably connected with two sliding blocks moving oppositely in the transverse direction and located below the air supply holes, a material passing slit with adjustable width is formed between the two sliding blocks, the control system also comprises an electric push rod fixedly arranged at the outer side of the side wall of the channel, anda push rod part of the electric push rod penetrates through the side wall of the channel to be fixedly connected with the sliding blocks. The uniform control system and control method for the nonwovenfabric have the advantages that the sliding blocks move transversely through the electric push rod, thereby achieving the adjustment of the passing cross-sectional area of the material, so that the thickness of the material entering a web former is more uniform, and irregular phenomena such as grooves are avoided; through the linkage of the sliding blocks and taper plugs, the ventilation area ofthe air supply holes is adaptive to the width of the passing slit between the sliding blocks, thereby ensuring the stable transportation of the material.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric thickness control, in particular to a nonwoven fabric uniformity control system and control method. Background technique [0002] At present, in the production of non-woven fabrics, the fibers are usually sprayed out through the spinning box, and the fibers are moved along the diffusion channel through the suction effect of the drafter and the suction unit, and attached to the web forming machine. Then go through hot rolling, coating, drying and other devices to form non-woven fabrics. However, only relying on hot rolling to control the thickness will often cause grooves in the product due to uneven feeding of raw materials. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a nonwoven fabric uniformity control system and control method. The system is located below the slit drafter and mainly compensates for the problem of unev...
