High-flux multi-card food safety detection equipment sample injection device

Abstract

The invention discloses a high-flux multi-card food safety detection equipment sample injection device which comprises a sample injection turntable and a sample injection tray in sliding fit with a host; the sample injection turntable is rotatably connected with the sample injection tray through a rotating shaft; a stepping motor capable of driving the sample injection turntable to rotate is arranged on the sample injection tray; a plurality of alignment grooves are formed in the top surface of the sample injection turntable; alignment bulges in one-to-one correspondence with the alignment grooves are arranged on the bottom surface of the sample injection turntable, and and the alignment bulges can be clamped with the corresponding alignment grooves; a photoelectric controller is further arranged on the sample injection tray, a light blocking plate is fixedly arranged on the bottom surface of the sample injection turntable, and the light blocking plate can block the photoelectric controller when the sample injection turntable rotates; and the photoelectric controller and the stepping motor are electrically connected with a program control module respectively. The high-flux multi-card food safety detection equipment sample injection device has the advantage that the food safety detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of food testing equipment, in particular to a high-throughput multi-card food safety testing equipment sampling device. Background technique [0002] Food safety is related to the health of the people and is valued by the state and the whole society. Food safety testing is an important means to ensure the safety of dining tables. Among the similar instruments for rapid detection of food safety at present, there are single instruments for detecting dry chemical detection card detectors, fluorescence detectors, and spectrophotometric detectors, among which are used for detecting dry chemical detection cards and immunocolloidal gold detection cards The current detector uses single-card sampling, which has low work efficiency, and most of them are qualitative tests; the fluorescence detector uses single-card sample injection and visual inspection, so the efficiency and accuracy cannot be guaranteed. Existing f...

Among the similar instruments for rapid detection of food safety at present, there are single instruments for detecting dry chemical detection card detectors, fluorescence detectors, and spectrophotometric detectors, among which are used for detecting dry chemical detection cards and immunocolloidal gold detection cards The detector is for single-card sample injection, with low work efficiency, and most of them are qualitative detection; the fluorescence detector is for single-card sample injection and visual inspection, and the efficiency and accuracy cannot be guaranteed after work.

Existing food safety rapid inspection equipment usually adopts a single card for sample inspection, and only one type of test card can be fed into a card feeding part for on-machine testing, and multiple test cards cannot be loaded, and each card cannot be used in the same batch. Prototype on-board detection brings problems with single-card detection
