Abstract

The invention discloses an automatic film replacing device of a particulate matter sampler. The device comprises a blank film barrel, an upper film opening, a sampling film barrel, a sliding groove upper plate, a sliding groove lower plate, a lower film opening, a compression spring, a film jacking support, a film jacking rod, a first guide rail, a direct current motor, a motor base, an automatic cam, an anti-falling sliding plate, a lead screw motor, a second guide rail, a push plate, a filter film clamp, extension springs, a back base plate and a cam plate. A sliding groove upper plate and a sliding groove lower plate are fixed to the back bottom plate, a blank membrane cylinder, an upper membrane opening and a sampling membrane cylinder are sequentially installed at the upper end of the sliding groove upper plate, a plurality of filter membrane clamps are arranged in the blank membrane cylinder, a sliding groove is formed between the sliding groove upper plate and the sliding groove lower plate, and a lead screw motor with a lead screw and a second guide rail are installed in the sliding groove. According to the invention, the push plate is matched with the anti-drop sliding plate, so that the filter membrane clamp can be automatically replaced, and the sampling efficiency and the sampling precision are improved; due to the arrangement of the non-return membrane buckle, the sampled filter membrane clamp is not easy to fall off.

Description

【Technical field】 [0001] The invention relates to the technical field of air detection, in particular to the technical field of particle samplers. 【Background technique】 [0002] Particulate matter content is an important indicator in air detection, and sampling membranes are often required for adoption. The sampling membrane on the existing sampling device often needs to be replaced manually, which is not only troublesome to operate, but also brings inconvenience to time measurement. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an automatic membrane changing device for a particle sampler, which can automatically change the membrane of the device and improve efficiency. [0004] In order to achieve the above object, the present invention proposes an automatic membrane changing device for a particle sampler, including a blank membrane cylinder, an upper membrane opening, a sampling membrane cyli...
