A uniform negative pressure roller web forming machine for meltblown equipment and a production process for meltblown cloth

Abstract

This application relates to the technical field of melt-blown cloth production, and aims to provide a uniform negative pressure drum-type web forming machine for melt-blown equipment and a production process for melt-blown cloth. and a winding mechanism located at one end of the frame in the discharge direction, the frame is provided with a first driving motor and a second driving motor, the first driving motor is used to drive the receiving drum to rotate, and the second driving motor is used to drive the winding mechanism to rotate; the receiving The drum includes an inner cylinder and a filter screen arranged on the outer layer of the inner cylinder. There are a number of ventilation holes evenly distributed on the wall of the inner cylinder, and a negative pressure guide cylinder is arranged in the inner cylinder along the axial direction, and the negative pressure guide cylinder is connected with a negative pressure. source; a pair of spreading rollers parallel to the receiving drum is installed below the receiving drum; the process of producing non-marking melt-blown cloth includes steps: raw material input, melt metering, die spinning, wire splitting, spreading Shaping, drafting and winding. The invention has the advantages of uniform melt-blown web formation and uniform cloth without traces.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production and manufacturing, in particular to a melt-blown equipment uniform negative pressure drum-type web forming machine and a melt-blown cloth production process. Background technique [0002] The manufacture of nonwovens by melt blowing is a general and cost-effective method of directly producing nonwovens with microfiber structures from polymers. The nonwovens produced by this method have excellent filterability, shielding properties, Thermal insulation and oil absorption, so it is widely used in the manufacture of medical and industrial masks, thermal insulation materials, filter materials, oil absorption materials and sound insulation materials and other fields. [0003] The Chinese patent with the authorized announcement number CN203754951U discloses a web forming device of a non-woven fabric melt-blown web forming machine, including a receiving drum, a winding roller, an upper...

Problems solved by technology

[0004] Although the existing technical scheme can improve the adaptability of the coiling tension of the coiling roller through the floating pressurization coiling mechanism, and reduce the phenomenon of wrinkling and unevenness of the cloth coiling caused by tension changes, in actual production, from the melt blown die head When the ejected microfibers are sprayed onto the surface of the receiving drum and spread and formed, there will be uneven formation. When the unevenly formed fabric is directly taken up by the take-up roller, it will cause fabric wrinkles and creases.
