When the spinneret hole is extruded, it is blown by the hot air flow on both sides of the spinneret hole, and the melt is stretched into warp-oriented superfine fibers, which are self-bonded to form polyurethane elastic non-woven fabrics. The existing non-woven fabric manufacturing devices include Yarn unwinding device, yarn tensioning device, heating composite device, heating flattening and shaping device, cooling device, fabric receiving device, control device, when in use, carbon yarn, etc. are pulled from the creel and enter through the yarn guide teeth Enter the yarn tensioning device, then enter the heating compound device, heat press and shape into a cloth, and then enter the heating, flattening and shaping device for finishing to become a non-woven primary cloth, and finally roll it into a roll through the cooling device and the cloth receiving device, and the yarn unwinding device There is a yarn release rack, on which there is a support shaft, carbon yarn, etc. is sheathed on the support shaft in a roll shape, and a guide correction device is provided on the support shaft, and the yarn is passively released by the tension of the yarn tensioning device. The distance between the yarn reel and the yarn tensioning device is not equal, the size of the yarn reel is not equal, and the tension of each yarn reel when entering the yarn tensioning device is different, resulting in uneven thickness and uneven surface of the non-woven fabric produced; The tensioning device for yarn entry is composed of multi-stage tensioning rollers, yarn guide teeth and brackets. The tensioning rollers are supported on the brackets at both ends. The tensioning rollers are adjusted by adjusting screws and nuts on the brackets. Its shortcomings are inconvenient operation, uneven adjustment, etc. The heating composite device is composed of six heating rollers and heating platforms that can be lifted up and down on the bracket. The composite pressure is adjusted by the lifting of the heating rollers. There is a mechanical (thread) pressure adjustment device on the brackets at both ends of the lifting roller, that is, there are roller gap adjustment handwheels and adjustment sliders. The adjustment of each roller gap depends on manual experience by turning the handwheel and adjusting the adjustment range by visual inspection. , its disadvantage is that the operation is inconvenient, the pressure and gap adjustment are not equal, resulting in poor product grades and low production efficiency. The cooling flattening and shaping device is composed of cooling plates and cooling rollers. Control the cooling temperature of the production line, and get the finished product after cooling. The quality inspection of the product is generally carried out after cooling, relying on manual hand scissors or cutting knives to take samples on site. The disadvantages are: defective products are formed in some positions of the product after sampling, and the real-time adjustment of data is slow. Affect the normal work of the production line, wherein the cloth receiving device is provided with a bracket, the bracket is equipped with a transmission shaft, the transmission shaft is driven by a torque motor, and two expansion air bags are embedded on the surface of the transmission shaft, and the output is determined by an external meter. The shortcoming of the meter meter is that the torque output is unstable at low speed, and the machine must be stopped every time the shaft is changed, and the counting of the meter meter is inaccurate due to material slippage and other reasons. The control device relies on many relay circuits to output control torque control. Brakes and magnetic powder brakes, a complex operating platform composed of several digital display instruments and knobs, its disadvantages are : It is complicated to adjust the parameters, and it is difficult to unify the data of each part of the instrument distribution production line, it cannot be controlled linearly and the output is unstable, and the maintenance cost is large.
