Description

Technical Field

[0001] The invention relates to a production equipment, in particular to a non-woven fabric production equipment, and belongs to the technical field of non-woven fabric production equipment. Background Art

[0002] Non-woven fabrics are composed of directional or random fibers and are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For example, polypropylene pellets are often used as raw materials and are produced in a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding. After the non-woven fabric is formed as a whole, in order to facilitate its winding, it needs to be cooled and shaped by cooling equipment. The existing cooling equipment will use multiple fans to directly blow air to cool its surface when in use, but the airflow blown to the non-woven fabric by multiple fans is not uniform, which will cause uneven heat dissipation of various parts of the non-woven fabric and wrinkle deformation. In view of the above problems, the present invention proposes a new solution. Summary of the invention

[0003] The main purpose of the present invention is to solve the deficiencies of the prior art and to provide a non-woven fabric production device and a non-woven fabric production method.

[0004] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0012] Preferably, two rows of evenly distributed limiting rods are installed inside the cooling box.

[0013] Preferably, the limiting rod is located between the first dispersion box and the second dispersion box.

[0014] A production method of a nonwoven fabric production device comprises the following steps:

[0015] Step 1: When cooling, the non-woven fabric passes through the inside of the cooling box through the feed port and the discharge port, so that the non-woven fabric is located between the first dispersion box and the second dispersion box, and the air supply box is started to supply air to the inside of the first booster box and the second booster box:;

[0016] Step 2: When the air pressure inside the first booster box and the second booster box is higher than the atmospheric pressure, open the solenoid valve and supply air to the first dispersion box and the second dispersion box through the first connecting pipe. The airflow will be dispersed by the dispersion mechanism and then blown toward the non-woven fabric passing between the first dispersion box and the second dispersion box, thereby cooling the non-woven fabric.

Through the arrangement of the pressure sensor, the air pressure inside the first booster box and the second booster box can be monitored. Through the arrangement of the first booster box and the second booster box, the gas can be pre-stored to ensure that the gas is more even and stable when discharged through the first connecting pipe.
