Problems solved by technology

[0004] However, the current non-woven fabric forming equipment, due to the drawing and stretching device, and the cold air supply device that provides compressed air flow to the inner wall of the drawing and stretching device, are only used as air passages, so there are shortcomings of excessive air flow velocity and uneven air supply. The wind speed of the non-woven fabric forming equipment is easy to cause non-uniform filament forming, the formed spinning filaments have different sizes, and even cause spinning breakage, which seriously affects product quality; at the same time, due to the existing web forming device of the non-woven fabric forming It is a carrier for carrying spinning to make it naturally laminated into a net, and as a carrier for conveying a mesh cloth, but the thickness of the web cannot be controlled, which will easily cause uneven thickness of the cloth, and during the transmission process, as the temperature drops, The surface bonding performance of spinning is reduced, and the non-woven fabric formed after rolling has low strength and is easy to loose

Embodiment 1

[0060] See Figure 1 ~ Figure 4 As shown, a kind of non-woven fabric forming equipment in this embodiment includes an extruding device, a spinning box 15 provided with a nozzle 16, a cold air supply device, a traction stretching device, a web forming device, and a hot rolling device 5 in sequence according to the material conveying direction. and winding device; the cold wind supply device includes a compressed air generating device 28 and a cold air box device, and the cold air box device includes a pair of boxes 21 which are respectively located on both sides below the nozzle 16, and each box body 21 is inside An air flow channel 211 is formed, and the box body 21 is provided with an air inlet 212 connected to the compressed air generating device 28. The air outlet of the box body 21 is directly below the nozzle 16, and the air flow channel 211 is close to the air outlet. An airflow deceleration plate 23 is provided, and the airflow deceleration plate 23 is provided with a h...

Embodiment 2

[0086] The winding device of this embodiment is different from that of Embodiment 1.

[0087] See Figure 8 ~ Figure 11 As shown, the rewinding device in this embodiment includes a rewinding frame 71, the rewinding frame 71 is provided with a conveying roller 72 and a rewinding roller set 73, and the rewinding frame 71 is pivotally provided with a knife holder 74 , the rear end of the knife holder 74 is pivotally connected to the winding frame 71 through a pivot parallel to the winding roller set 73 , and a pair of cutting knives 75 perpendicular to the winding roller set 73 are arranged at the front end.

[0088] Wherein, the number of the transmission rollers 72 is at least two; the winding roller set 73 includes a front winding roller 731 and a rear winding roller 732 which are parallel to each other and positively rotate in opposite directions. During the winding process, the formed non-woven fabric webs are staggered around the conveying roller 72 in turn, then staggered...

Abstract

The invention discloses non-woven fabric forming equipment comprising an extruding device, a spinning beam, a packaged air conditioner device, a drawing and stretching device, a net-forming device, a hot rolling device and a wrap-up device, wherein an airflow speedbrake is arranged on the packaged air conditioner device; a closed inner cavity is formed on the drawing and stretching device; an adjusting plate is arranged on the cavity wall and is connected with an adjusting device; a prepressing roller pair is arranged on the net-forming device and also arranged between the position below the drawing and stretching device and the position of the hot rolling device; the airflow speedbrake has the functions of reducing the speed and stabilizing flow, thereby ensuring that the non-woven fabric forming equipment can uniformly spin; the adjusting device enables the bending degree of the adjusting plate to be changed, thereby adjusting the section shape and the caliber of the inner cavity, changing the drawing force of the airflow on a polymer and adjusting and controlling the forming diameter of spinning; and by using the prepressing of the prepressing roller on the fabric width, the invention is beneficial to improving the compactness and the strength of fabrics and ensures that the fabric width thickness is uniform.

Description

Technical field [0001] The invention involves the field of fabric manufacturing equipment technology, and specially involves a non -weaving molding equipment. Background technique [0002] No woven fabric, that is, non -woven fabrics, is widely used in one -time consumer goods, or packaging such as one -time absorption of products.There is a typical non -woven fabric manufacturing method to spray the melting state of the melting state with a nozzle, so that the polymer cools to form filaments and machine spinning. These spinning wires are paved into a mesh, and the cloth is formed after rolling. [0003] The above method is used to create a device that is not weaved. Generally, the melting state polymer entered by a extruder is spin into multiple single wires in the spinning box through a column or line -shaped nozzle hole.With the help of a gap -shaped traction stretching device set at a certain distance below the single silk, the traction is applied to the single silk.To this e...
