Melt-blown fiber production mechanism

Abstract

The invention discloses a melt-blown fiber production mechanism, and relates to the technical field of melt-blown cloth fiber production equipment. The melt-blown fiber production mechanism comprises a shell, a wind-up roller and a melt-blown machine body, wherein the inner wall of the shell is further rotationally connected with a transmission shaft through a fixed shaft; and the surface of the transmission shaft is in transmission connection with the wind-up roller and any one belt pulley I through a transmission part and synchronously rotates with the wind-up roller and any one belt pulley I. The melt-blown fiber production mechanism further comprises a monitoring component for detecting the spinning speed of the melt-blowing machine body, and an auxiliary component I for automatically reducing the rotating speed of the transmission shaft along with increase of the spinning speed of the melt-blowing machine body, wherein the monitoring component is in signal connection with a telescopic driving component; and the auxiliary component I is in transmission connection with a motor. The melt-blown fiber production mechanism provided by the invention has the advantages that once the spinning speed of a discharge hole in the melt-blowing machine body is increased, the spinning blanking distance can be automatically adjusted, the final blanking speed is changed, meanwhile, the winding storage speed of the wind-up roller on the melt-blowing cloth is reduced, the contact time of the melt-blowing cloth and air can be prolonged, and heat carried by the melt-blowing cloth is transferred into the air.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth fiber production equipment, in particular to a melt-blown fiber production mechanism. Background technique [0002] Melt-blown nonwovens are manufactured using molds. The production process is to use high-melt index raw materials, heat and pressurize them into a molten state through a screw extruder, pass through the mold, and the melt distribution channel reaches the spinneret hole at the front end of the nozzle. After extrusion, it is stretched by two convergent high-speed and high-temperature air streams to make it thinner. After passing through a certain height, it is sprayed onto the fabric splicing machine, and the thinned fibers are cooled and solidified on the mesh curtain device to form a melt-blown nonwoven fabric. [0003] In the actual production process, in order to increase the strength and elongation, the hot air flow rate or temperature is generally increased, so the spinn...

Problems solved by technology

[0004] The purpose of the present invention is to provide a melt-blown fiber production mechanism, which can automatically adjust the blanking distance of the spinneret once the spinning speed of the discharge hole on the melt-blown machine body increases, so that the final blanking speed can be changed, and at the same time The winding speed of the rewinding roller for the melt-blown fabric is reduced, so that the melt-blown fabric can increase the contact time with the air, and the heat carried on it is transferred to the air, which solves the problem of manually adjusting the spacing of the spinning and blanking. It is time-consuming and laborious, and the efficiency is low, and it is difficult to integrate the blanking speed with the winding speed of the melt-blown cloth, which may easily lead to heat accumulation of the rolled-up melt-blown cloth, which brings inconvenience to use
