Melt-blown fabric and device for processing the melt-blown fabric

Abstract

The invention discloses melt-blown fabric and a device for processing the melt-blown fabric. The device comprises a melt-blowing machine base, one end of the melt-blowing machine base is fixedly connected with a metering pump, and the input end of the metering pump is electrically connected with the output end of an electric supply. The other end of the metering pump is fixedly connected with a melt filer, and one side of the melt filter is fixedly connected with an extruder. A solid material adding mechanism is arranged at the other end of the melt-blowing machine body. According to the melt-blown fabric and the device for processing the melt-blown fabric, a functional additive is contained at the top of a mixing cavity through a storage cavity, a servo motor drives a driving convex blockto rotate, and the driving convex block and a transmission convex block cooperate to drive a feeding screen plate to slide along the top of an adding screen plate; and under the action of a telescopic spring and a sliding plate, the feeding screen plate is reset, then the additive in the storage cavity continuously and evenly fall into the mixing cavity, so that the additive and the melt-blown fabric are combined more firmly, and meanwhile the additive is more even in the melt-blown fabric.

Description

technical field [0001] The invention relates to the technical field of melt blown cloth production equipment, in particular to a melt blown cloth and a device for processing the melt blown cloth. Background technique [0002] Melt-blown cloth is the core material of masks. Melt-blown cloth mainly uses polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. It has many voids, fluffy structure, good wrinkle resistance, and ultra-fine fibers with unique capillary structure. Increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption, and can be used for air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, In the fields of oil-absorbing materials and wiping cloths, melt-blown cloth production equipment is required in the production process of melt-blown cloth; [0003] However, during t...

Problems solved by technology

[0004] The present invention provides a kind of melt-blown cloth and a device for processing the melt-blown cloth, which can effectively solve the problem that in the production process of the melt-blown cloth production device proposed in the above-mentioned background technology, in order to improve the comprehensive performance of the melt-blown cloth, the powdery function The non-toxic additives are sprayed onto the melt-blown cloth, causing most of these additives to be distributed on the outside of the melt-blown cloth. At the same time, because these additives are sprayed onto the melt-blown cloth in the later stage, the connection between the additive and the melt-blown cloth is not strong enough. Additives tend to fall off during the use process, which reduces the quality of the product
