A meltblown mold

Abstract

The invention discloses a meltblown mold, which includes two upper molds, flanges, cleaning valves, transparent covers, cleaning components, connecting plates, spinnerets, multiple air knife plates, and multiple air pipes; the cleaning components include Sleeve, sealing cover, push rod, multiple connecting rods, hollow cylinder, cleaning head; the first spring is set on the cleaning head; one end of the cleaning head is in contact with the hollow cylinder, and a convex There is no fixed connection between the spinneret, the upper die and the connecting plate of the present invention, which is convenient for the spinneret to be removed and maintained separately, so that the spinneret can be replaced quickly and the downtime is reduced; at the same time, a cleaning component is provided, through which the working , in daily maintenance, you only need to put the sleeve into the meltblown mold and adjust the push rod and cleaning head to quickly clean up the internal residues without disassembling the meltblown mold for separate cleaning. The operation is simple and the maintenance difficulty is reduced. The time required for maintenance or cleaning can prevent the mold from being damaged by repeated manual disassembly and assembly, and reduce maintenance costs.

Description

technical field [0001] The invention belongs to the technical field of melt-blown cloth production, and in particular relates to a melt-blown mold. Background technique [0002] Non-woven fabrics mostly use polypropylene pellets as raw materials, which are moisture-proof, breathable, flexible, light in weight, non-combustible, and recyclable. Non-woven fabric has no warp and weft, and is light and easy to shape. It is very convenient to cut and sew. It has become the material of choice for mask production. Non-woven fabrics are produced by melt-blown molds. Polypropylene pellets are made into hot fluid in the injection molding machine and injected downward through the spinneret holes of the melt-blown mold. At the same time, the threads are pulled out under the action of wind on both sides. On the spinneret, the hole diameter is extremely small, mostly 0.1-0.3mm, and the spacing is 0.6-0.7mm. For example, a 550mm mold has nearly 1,000 holes, so the mold is easy to block and...

Problems solved by technology

However, the existing spinneret and other parts of the mold are generally fixed together by screws, and there is no cleaning position reserved on the mold. The mold needs to be completely disassembled for daily maintenance. The mold itself is heavy and difficult to disassemble. The disassembly process is complicated and time-consuming. , affecting the production process
