Membrane pressing device for dust and gas sampling head

Abstract

The invention discloses a filter membrane lamination device for smoke and gas sampling head, which comprises a plurality of lamination modules, and each lamination module includes: an inclined guide post, a slider platform, a slider and a lamination tooth, an oblique guide The upper end of the column passes through the through groove from the bottom of the slider platform and enters the chute. When the transmission part moves vertically, it drives the inclined guide column to move upward or downward, and the inclined guide column drives the slider to move horizontally through the chute, and the sliding The front end of the block is obliquely matched with the rear end of the pressing teeth. There is a circular shaft at the bottom of the pressing teeth. At the same time, it rotates around the circular axis to perform pressing action; when the slider moves backward horizontally, the rear end of the pressing tooth moves backward under the pulling force of the slider, and at the same time rotates around the circular axis in the opposite direction to loosen. open action. The invention is a high reliability, long service life and low energy consumption filter membrane press-fitting device for a smoke and gas sampling head.

Description

Filter Membrane Press Fitting Device for Smoke Sampling Head technical field The present invention relates to the technical field of soot and flue gas sampling, in particular to a kind of high reliability, long service life and low energy consumption The filter film pressing device is used for the smoke and gas sampling head. Background technique Low-concentration smoke and dust sampling adopts weighing method to sample, and sampling head, filter membrane, sealing ring, net support need to be collected during sampling. Press into a whole, and weigh the whole after sampling. Most of the existing lamination devices are manual lamination devices. The rotary indenter realizes the lamination process, which is cumbersome in operation, low in lamination efficiency and high in defect rate. There are also automatic pressure Membrane device, however, its structure is mostly converted from rotary motion to linear reciprocating motion, and its transmission mechanism has many p...

AI Technical Summary

Problems solved by technology

Most of the existing lamination devices are manual lamination devices. The lamination process is realized by manually rotating the pressure head during lamination. The operation is cumbersome, the lamination efficiency is low, and the defect rate is also high.

There are also automatic film lamination devices on the market, but most of their structures are converted from rotary motion to linear reciprocating motion. The transmission mechanism has many parts and requires high dimensional accuracy, and the energy loss during the motion conversion process is huge, resulting in a high load on the motor. There are often problems such as jamming, motor damage, and large power consumption.

The existing automatic film laminating machine has been criticized by consumers for its low product life and poor experience.
