Description

Technical Field

[0001] The utility model relates to the technical field of nonwoven fabric production equipment, in particular to a rotary filament-separating and web-laying device. Background Art

[0002] In the production process of nonwoven fabrics, the fiber separation effect and laying state directly determine the uniformity of the fabric surface and physical properties. At present, the commonly used fiber separation and laying methods for tubular drawing are air flow separation and laying, electrostatic fiber separation and laying, mechanical rotary fiber separation and laying, etc.

[0003] The existing equipment uses air flow to separate the yarns and use swing blades to impact and scatter the yarns for laying. The strength index of the cloth surface is acceptable, but since the trajectory of the yarn bundles after being scattered by the swing blades cannot be accurately controlled, there are obvious cloud spots on the cloth surface and the product uniformity index is poor.

[0004] The electrostatic wire splitting device is a wire splitting device commonly used in tubular drafting to improve the wire splitting effect and reduce cloud spots. It uses the principle of like charges repelling each other, so that each bundle of wire has the same charge to achieve the purpose of improving the wire splitting effect. Its shortcomings are that the wire splitting state of the wire bundle after electrostatic wire splitting is difficult to control accurately, and the fibers will move in the electrostatic area, affecting the stability of the electrostatic area, and the gas generated by high voltage breaking through the air is harmful to the human body.

[0005] Mechanical rotary wire laying method, such as patent number CN207878028U, discloses a rotary laying device for spunbond nonwoven fabrics, which lays the tows on the conveyor curtain into a uniform circular cloth effect. Its structure is to drive the gear and the metal tube with a certain angle to make a circular motion, replacing the traditional horizontal swing plate wire laying device and the slit wire laying device. Its shortcomings are that the bending angle of the metal tube at the lower end of the device cannot be adjusted, and the wire laying effect cannot be guaranteed; the noise is large during production, and the stability of the equipment is poor when it is continuously running at high speed, and the mechanical structure is easily damaged, making it difficult to ensure continuous and stable production.

[0007] The utility model mainly comprises a diffuser, an upper fixing plate, a stepping motor, a lower fixing plate, a wire dividing tube and a wire dividing sheet.

[0008] Among them, several diffusers are arranged on the upper fixed plate, the lower end of each diffuser extends to the lower part of the upper fixed plate and is connected to the corresponding hollow stepper motor, and several hollow stepper motors are arranged on the lower fixed plate, and their rotating shafts extend to the lower part of the lower fixed plate and are connected to the corresponding wire splitting tubes. A wire splitting sheet is arranged at the lower part of each hollow wire splitting tube.

[0009] Preferably, the wire dividing sheet is composed of a first wire dividing sheet and a second wire dividing sheet connected together, the first wire dividing sheet is connected to the lower part of the hollow wire dividing tube, and the first wire dividing sheet and the second wire dividing sheet are at an angle of 15 to 60 degrees.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The hollow stepper motor adopts a driver controller. The hollow stepper motor can switch between circular motion and rotary motion. While ensuring that the hollow stepper motor does not lose steps, the trajectory of the tow is stably controlled to ensure the uniformity of the cloth surface.

[0012] 2. The fibers are guided by the airflow and hit on the wire splitting sheet. The wire splitting angle can be adjusted by replacing the wire splitting sheet, ranging from 15 degrees to 60 degrees, and the wire splitting effect is significantly improved. The hollow stepping motor is used to rotate the wire splitting, which can reduce noise and equipment wear while achieving energy saving and consumption reduction. BRIEF DESCRIPTION OF THE DRAWINGS
