Description
Technical Field
[0001] The utility model relates to the technical field of coding of centrifuge tubes, and particularly relates to a coding device for centrifuge tubes. Background Art
[0002] A centrifuge tube is a tubular sample container, which is a common experimental container widely used in laboratories and industrial applications. It is mainly used to separate and analyze particles or components in liquid suspensions. A centrifuge tube consists of a tube body and a tube cap. The tube body is the main part of the centrifuge tube, and the bottom of the tube body is usually conical, so that the bottom of the tube body helps the sediment to deposit at the bottom of the tube during centrifugation. The tube cap is used to seal the tube body to prevent the sample from splashing out or being contaminated during separation and analysis. Centrifuge tubes are divided into screw-cap centrifuge tubes and plug-cap centrifuge tubes according to the closing method of the cap. For a screw-cap centrifuge tube, threaded grooves are respectively provided at the inner cavity of the tube cap and the tube orifice of the tube body, and the tube cap is screwed onto the tube body to realize the sealing of the tube body. However, due to reasons such as the tube cap not being screwed tightly enough, the screw-cap centrifuge tube sometimes leaks liquid, which has an adverse impact on the development of separation and analysis operations. For a plug-cap centrifuge tube, the bottom of the tube cap is designed in the shape of a plug, and the bottom of the tube cap is press-fitted onto the tube orifice of the tube body to realize the sealing of the tube body. Due to the good sealing performance of the plug-cap centrifuge tube, the plug-cap centrifuge tube is usually more preferred as an experimental container for sample separation and analysis operations in laboratories and industrial applications.
[0003] In order to prevent the tube cap from being lost during use and also to facilitate press-fitting the tube cap inside the tube body, side ears made of elastic materials are usually installed at the tube orifice of the tube body. One side of the side ear is fixed to the tube cap, so as to realize the connection between the tube cap and the tube body. In this way, when using a plug-cap centrifuge tube, only need to buckle the tube cap on one side of the tube body onto the tube orifice of the tube body, and the sealing of the tube body can be quickly realized. However, in order to know the relevant information of the sample filled in the plug-cap centrifuge tube, labels are usually attached to the outer wall of the tube body to facilitate identifying the information of the sample according to the information on the label. However, this traditional label attachment method has some problems. First, it consumes a large amount of glue and paper, which not only increases the cost but also has a certain impact on the environment. Second, since the label is easy to fall off during use, it is difficult to accurately identify the sample, which affects the accuracy and reliability of the experiment.
[0004] To solve these problems and reduce the use of paper and glue, an inkjet printer is used to perform inkjet coding on the outer wall of the tube body. In this way, relevant information can be pre-marked on the outer wall of the tube body, thus avoiding the problem of label shedding. To facilitate the sequential delivery of multiple centrifuge tubes to the inkjet end of the inkjet printer for inkjet coding, a conveyor belt is used to transport the centrifuge tubes to the inkjet end of the inkjet printer for inkjet coding. However, since the overall shape of the centrifuge tube is cylindrical, it is inevitable that the centrifuge tube will roll during the transportation process. This rolling phenomenon will affect the positioning of the centrifuge tube, thereby affecting the accuracy and efficiency of inkjet coding. Therefore, how to keep the centrifuge tube stable during transportation and ensure that it can be accurately inkjet coded has become an important problem to be solved. Summary of the Invention
