Test tube shaking device for food detection

Abstract

The invention relates to the technical field of detection instruments, in particular to a test tube shaking device for food detection, which comprises a base, a support frame, a support plate, a trackplate, a limiting plate, a track block, a rocker arm and a servo motor; wherein a first hinge shaft is fixedly arranged on the track plate, a second hinge shaft is fixedly arranged on the support frame, and the second hinge shaft is rotatably matched with a swing arm; a first sliding block is slidably arranged in the first sliding groove, a first hinged shaft is rotatably matched with the first sliding block, an output shaft of the servo motor is fixedly connected with an eccentric wheel, an eccentric shaft is fixedly arranged on the eccentric wheel, a second sliding groove is formed in the swing arm, and a second sliding block is slidably arranged in the second sliding groove and rotatably matched with the eccentric shaft. According to the invention, when the servo motor drives the swingarm to periodically swing left and right in a reciprocating mode, reciprocating movement of the rail block in the rail groove is achieved, and horizontal movement and degree deflection of the test tube barrel are achieved, so that the liquid in a test tube in the test tube barrel can be fully shaken up, the shaking amplitude of the device is large, and the shaking efficiency is high.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a test tube shaking device for food detection. Background technique [0002] In the process of food testing, it is often necessary to shake the samples or detection reagents in the test tubes. The existing test tubes lack a shaking device, and manual work is required to shake the samples or detection reagents in the test tubes. This process is time-consuming and laborious. It not only reduces the Food detection efficiency, and it is easy to mix the samples or detection reagents in the test tube unevenly and thoroughly, resulting in insignificant detection effect. [0003] The invention application with the publication number CN106890593A discloses a wave-type laboratory test tube automatic shaking device, which consists of a base, a control box, an L-shaped mounting bracket, an eccentric shaft, an eccentric wheel, a stepping motor No. 1, a connecting rod, and a test...

AI Technical Summary

Problems solved by technology

The application for the invention uses the eccentric wheel and the connecting rod to drive the fluctuation plate of the test tube plate to fluctuate up and down to realize the vertical shaking of the liquid in the test tube, thereby realizing the shaking operation of batch test tubes. The degree is not high, and the problem of low shaking efficiency
