A production and processing system for absorbent melt-blown cloth

Abstract

The present invention relates to the technical field of meltblown cloth production and manufacturing machinery, in particular to an absorbent meltblown cloth production and processing system, which includes meltblown equipment, negative pressure forming equipment and rolling equipment along the processing and forming direction of meltblown cloth. A forming belt for forming melt-blown cloth is installed on the rotary of the press-forming equipment. Protruding tensioning ribs are provided on both sides of the forming belt in the width direction, and a tensioning belt is installed between the melt-blown equipment and the negative pressure forming equipment. Equipment, between the meltblown equipment and the tensioning equipment, there is an air guide device, and by using the tensioning equipment that is rotated on both sides of the forming belt, the tensioning claws on the tensioning equipment are used to align the width direction of the forming belt. The edge of the belt is tensioned, so that the forming belt is tensioned in the width direction, so as to prevent the forming belt from being sucked by the negative pressure forming equipment and sprayed by the melt-blown mold, and the forming belt is bent and the quality of the formed melt-blown cloth is poor.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production and manufacturing machinery, in particular to an absorbent melt-blown cloth production and processing system. Background technique [0002] Meltblowing is a method for forming nonwoven meltblown fabrics of thermoplastic (co)polymer fibers. In a typical melt blown process, one or more thermoplastic (co)polymer streams are extruded through a die containing densely arranged spinneret holes and attenuated under the action of a converging flow of high-velocity hot air to form microfibers, which are Collected to form a meltblown nonwoven meltblown fabric. [0003] Thermoplastic (co)polymers commonly used to form conventional meltblown nonwoven meltblown fabrics include polyethylene (PE) and polypropylene (PP). Meltblown nonwovens are used in a variety of applications including acoustic and thermal insulation, filter media, surgical films and wipes, and many more [0004] In patent...

AI Technical Summary

Problems solved by technology

[0008] In view of the above problems, the present invention provides a production and processing system for absorbent melt-blown cloth. By using a cleaning assembly between the screw extrusion mechanism and the spray head, the cleaning assembly is used to clean the air supply to the spray head. The air source is switched so that when the screw extrusion mechanism and the spray head stop working, the gas provided by the external air source can be filled into the interior of the cleaning assembly through the airtight channel, and then the residual gas in the spray head will be removed by using the gas. The raw materials are extruded from the spray head to ensure the cleanliness of the spray head and solve the problem of blockage of the spray head
