Problems solved by technology

[0002] In the existing filament laying technology, the fiber tow extruded from the extruder is only flattened by the rollers once, and is directly blown into a entangled weaving state by the fan, and then enters the laying machine through the conveying device, and the thickness is not uniform. , the entanglement weaving range is small, and the transverse tension is poor, which is the defect of the prior art

Embodiment Construction

[0013] in figure 1 In the process, the tow (1) is flattened by the fixed flattening device (2) and the adjustable flattening device (3), the handwheel screw (4) is used to adjust the counter-rolling gap, and it is sent by the conveying device (5). Enter the swing device (6) to close. The filaments that are swung into the blowing device (7) through the nip roll and blown into a tangled and braided state are adsorbed on the negative pressure conveying device (8) and enter the next process.

[0014] in figure 2 In the combination of a plurality of fixed flattening rollers (9), a plurality of synchronous wheels (10), a frequency conversion motor (11) and a fixed bracket (12), the main body connecting holes (13) and Image 6 The fixing bracket connection holes (34) distributed in the middle are connected and fixed.

[0015] in image 3 In the process, the screw handwheel (14) is used to adjust the gap between each adjustable flattening roller (15) and the fixed flattening roller (9). ...

Abstract

The invention discloses a chemical fiber filament flattening web former, which can solve the technical problems of non-uniform flattening, low snarling amplitude and poor tensile strength of non-woven fabrics. Filament bundles are rolled and flattened through multiple rollers of a fixed flattening device and an adjustable flattening device, the rolling clearance is adjusted by using a hand wheel screw, the filament bundles are conveyed to a swing device through a conveying device and enter a blowing device by simultaneous swing of clamping rollers, and the filaments blown to a snarling weaving state are conveyed to a next process by a negative pressure conveying device.

Description

Technical field [0001] The invention relates to a non-woven non-woven machine, especially a filament spreading and laying net equipment. Background technique [0002] In the existing filament laying technology, the fiber tow extruded from the extruder is flattened by the rollers only once, and then blown directly by the fan into a tangled and weaving state, and then enters the netting machine through the conveying device, with uneven thickness , The tangling and weaving amplitude is small, and the lateral tension is poor, which is the defect of the prior art. Summary of the invention [0003] The use of multi-rollers to adjust and flatten the fiber tow, and the double sticks to clamp the fiber swing technology, improve the flattening effect and increase the transverse entanglement weaving strength. [0004] The technical solution adopted by the present invention includes: a fixed flattening device, an adjustable flattening device, a conveying device, a swinging device, a blowing de...
