The invention discloses a melt-blowing hopper for melt-blown cloth production. The melt-blowing hopper comprises a sealing hopper; a melt-blowing mechanism is installed at the lower end of the sealing hopper; the melt-blowing mechanism comprises a flow equalizing box fixed to the sealing hopper; a plurality of spraying pipes are inserted into the bottom wall of the flow equalizing box at equal intervals; a high-position airflow pipe and a low-position airflow pipe are inserted into the side wall of each spraying pipe; and each high-position airflow pipe and each low-position airflow pipe are connected with a high-position hose and a low-position hose respectively. By integrating feeding, hot melting and melt-blowing for the sealing hopper, the space occupancy rate is reduced, and the labor amount of manual operation is reduced; a melt is stretched and sprayed out twice through high-low-position pressure-dividing and speed-dividing airflow jetting stretching, so that the fineness of melt-blown fibers is increased, namely the filtering performance of melt-blown cloth is improved; directional airflow is formed by means of the pressure difference between cavities; and the functions of feeding, blocking prevention, hot melting and spraying are achieved synchronously, so that the number of equipment is reduced.
Description
technical field [0001] The invention relates to the technical field of fiber textiles, in particular to a melt-blown hopper for producing melt-blown cloth. Background technique [0002] The existing melt-blown hopper only has the function of feeding and discharging when producing melt-blown cloth. Both its hot-melt and melt-blown require the cooperation of screw extruders, air jet machines, high-temperature fans, etc., so that the melt-blown cloth The production machinery is huge in size and requires a large space for placement, which reduces the effective utilization of space. In addition, the existing melt blown usually uses high-speed airflow to stretch the melt, which directly stretches the melt at one time. The thickness of the fibers formed by stretching is not uniform enough, so that the distribution density of the formed melt blown cloth is not uniform, which reduces the filterability of the melt blown cloth, and when feeding, it is necessary to manually pour raw mat...
