Melt-blown cloth mold

Abstract

The invention relates to a novel melt-blown cloth mold. The mold comprises a feeding port, and materials enter the mold through the feeding port. In view of the pressure reduction effect of the mold,after entering the feeding port, the materials make a turn by 90 degrees firstly and then downwards enter branch flow channels, and according to the distance from each branch flow channel to the feeding port, the part from a main flow channel to each branch flow channel is designed as a dovetail shape, so that the purpose of uniform material distribution is achieved; and the materials pass throughthe feeding port and then enter a distribution plate, and the distribution plate evenly distributes material flow to the next spinneret plate, so that the distribution plate plays a role in flow distribution and plasticizing improvement, the flow speed and the flow direction of the material flow can be effectively controlled, and the effect of controlling the materials is achieved. The mold is high in spinning speed, uniform in spinning and low in loss and maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of cleaning and separating equipment, and in particular relates to an air flotation cleaning and separating device for cleaning plastics. Background technique [0002] In the process of melt-blown cloth processing, it is necessary to use the spinneret die to spray the melt-blown wire, and the spinneret die head on the spinneret die uses a hot air system to blow the mold to spray the melt-blown wire. In the prior art, there is no compression section in the spinneret hole of the spinneret die, which leads to slow spinneret speed and thick filaments, and the die does not flow to the distribution plate, so the material flow cannot be well controlled , resulting in uncontrollable spinning speed of the spinneret, and the integrated structure of the spinneret inlet plate, which is inconvenient to disassemble, low in production efficiency, and inconvenient to production.
