Device for conveying plastic test tubes

Abstract

The invention discloses a device for conveying plastic test tubes. The device comprises a test tube bin, a carrying platform, a material distributing device and a test tube flow channel. An upper opening is formed in the upper portion of the test tube bin, and a cone-shaped bin and a test tube outlet connected with the cone-shaped bin are arranged on the lower portion of the test tube bin. The longitudinal dimension and the transverse dimension of the test tube outlet are matched with diameters and lengths of the test tubes. The carrying platform comprises a test tube gap and is located below the test tube bin, and the vertical height from the lower edge of the test tube outlet to the upper surface of the carrying platform is equal to or larger than the diameter of one test tube and smaller than the sum of the diameters of two test tubes. The material distributing device comprises a material distributing plate and is installed above the carrying platform, and the test tube flow channel comprises a flow channel opening and is installed below the carrying platform. According to the device for conveying the plastic test tubes, through cooperation of the test tube bin, the material distributing device and the test tube flow channel, the purposes that one test tube is output at one time and an opening of each test tube is upward are achieved, manual repeating labor is liberated, reliability and stability of test tube outputting are high, and external interference factors are less, so that the device for conveying the plastic test tubes has obvious advantages.

Description

technical field [0001] The invention belongs to the field of analytical instruments, in particular to a device for transporting plastic test tubes. Background technique [0002] At present, in various analysis experiments, it is necessary to collect various types of samples for detection and analysis when performing various types of tests, and the test tubes are generally placed manually, and the repetitive work is not conducive to automation integration; There is a transmission test tube mechanism disclosed in the technology. The transmission mechanism consists of a chute for storing test tubes and a test tube output assembly formed by the cooperation of multiple conveying plates. It is not conducive to the integration of automation, and requires multiple collisions and guidance during the process of entering the blanking port, which can easily cause changes in the stability, reliability and operational accuracy of the test tube, and at the same time the efficiency is not h...
