Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a high-speed airflow extrusion mechanism for melt-blown non-woven fabric production. Background Art

[0002] The meltblown nonwoven fabric factory is different from the traditional spunbond production. It uses high-speed hot air flow to stretch the polymer trickle sprayed out of the spinneret hole of the module, turning it into an ultra-fine short fiber, which is guided to the roller for cooling and formed by its own viscosity. The production process is a flow process, from the loading and unloading of polymer materials to the melting and extrusion of materials, which are metered by the metering pump and sprayed out using a special spinneret hole module. The high-speed hot air flow stretches and guides the polymer trickle from the spinneret hole reasonably, and then forms it on the roller after cooling, and then receives and processes the materials at the lower end. All of these are done in one go. If there is a problem in any link, it may cause production interruption. Problems must be discovered and dealt with in a timely manner.

[0003] For example, a high-speed airflow extrusion mechanism for melt-blown nonwoven fabric production with publication number CN219450067U includes a mounting plate, two groups of mounting plates, a conveying roller is arranged in the middle of the inner side of the two groups of mounting plates, a support plate is fixedly installed in the middle of the bottom end of the conveying roller, a connecting block is arranged in the middle of both ends of the supporting plate, a screw rod is rotatably installed in the middle of the inner side of the connecting block, a motor is fixedly installed in the middle of the bottom end of the screw rod, the motor is fixedly installed at the inner bottom of the mounting plate, a spraying die head is arranged in the middle of the upper part of the mounting plate, the conveying roller is located in the middle of the lower part of the spraying die head, and a feed pipe is arranged in the middle of the top of the spraying die head. The utility model drives the screw rod to rotate by the motor, so that the connecting block slides vertically in the middle of the inner side of the limiting slide, thereby facilitating the adjustment of the vertical height of the conveying roller, so that the distance between the conveying roller and the spraying die head can be reasonably adjusted, and the quality of non-woven fabric spraying production can be improved.

[0004] Although the above technical solution can adjust the distance between the extrusion die and the conveying roller in practical applications, the position between the extrusion die and the hot air flow remains fixed, and the raw material is constantly affected by the hot air flow after extrusion, making it difficult to make reasonable adjustments.

[0005] Therefore, it is necessary to invent a high-speed airflow extrusion mechanism for melt-blown nonwoven production to solve the above problems. Utility Model Content
