An automatic filtration efficiency tester for meltblown cloth

Abstract

The invention discloses an automatic filtration efficiency tester for melt-blown cloth, comprising a body and an operation box fixedly connected to one side of the top of the body. The clamping and leveling mechanism includes an adjusting rod and a bottom frame, the top of the inner wall of the bottom frame is fixedly connected with a double-rod hydraulic cylinder through a connecting block, and the two extending ends of the double-rod hydraulic cylinder are fixedly connected with a vertical cylinder. The top of the vertical rod penetrates through the bottom frame and extends to the top of the bottom frame. The invention relates to the technical field of meltblown cloth detection. The automatic filter efficiency tester for melt-blown cloth can realize the clamping limit and automatic leveling operation of the melt-blown cloth, so as to avoid the problem that the melt-blown cloth is wrinkled during the test, which will affect the subsequent test results. The use of box doors and operating gloves also reduces safety hazards and lays the foundation for the accuracy of test results.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth detection, in particular to an automatic filtration efficiency tester for melt-blown cloth. Background technique [0002] Meltblown cloth is the core material of masks. Meltblown cloth is mainly made of polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. Increase the number and surface area of ​​fibers per unit area, so that the meltblown 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, Oil absorbing materials and wiping cloths and other fields. [0003] The filtration efficiency tester is an instrument used in the fields of material science, textile science and technology, and safety science and technology. It mainly tests the filtration efficiency of materials. [0004] The dust filtration e...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic filter efficiency tester for melt-blown cloth, which solves the problem of manually tiling the melt-blown cloth to prevent wrinkles, which is inconvenient and has certain safety hazards. At the same time, the heat dissipation inside the tester for a long time consumes more power resources, and the external dust is easy to enter the inside of the tester during heat dissipation, which affects the normal operation of internal devices.
