Automatic filtering efficiency tester for melt-blown cloth

Abstract

The invention discloses an automatic melt-blown cloth filtering efficiency tester which comprises a machine body and an operation box fixedly connected to one side of the top of the machine body, a heat dissipation mechanism is arranged in the machine body, a clamping and leveling mechanism is arranged in the operation box, and the clamping and leveling mechanism comprises an adjusting rod and a bottom frame. A double-rod hydraulic cylinder is fixedly connected to the top of the inner wall of the bottom frame through a connecting block, vertical rods are fixedly connected to the two extending ends of the double-rod hydraulic cylinder, and the top ends of the vertical rods penetrate through the bottom frame and extend to the top of the bottom frame. The invention relates to the field of melt-blown cloth detection. According to the automatic filtering efficiency tester for the melt-blown cloth, the clamping and limiting of the melt-blown cloth and automatic flattening operation can be achieved, the problem that the follow-up test result is affected due to the fact that the melt-blown cloth is wrinkled during testing is avoided, manual flattening is not needed, meanwhile, potential safety hazards are reduced due to the arrangement of a box door and operation gloves, and a foundation is laid for the accuracy of a test result.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth detection, in particular to an automatic filter efficiency tester for melt-blown cloth. Background technique [0002] Meltblown cloth is the core material of masks. Meltblown 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 ultrafine 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, Oil-absorbing materials and wipes and other fields. [0003] Filtration efficiency tester is an instrument used in the fields of material science, textile science and technology, and safety science and tech...

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.
