Description

Technical Field

[0001] This application relates to a top-and-bottom flipping device, specifically, to a top-and-bottom flipping device for mixing and shaking large-capacity containers, belonging to the field of equipment. Background Technology

[0002] In laboratory solvent mixing, the inversion method is commonly used: with the nozzle blocked, the container containing the solvent is inverted several times to ensure thorough mixing. This method utilizes the downward flow of the solvent under gravity during mixing, causing gas to flow through and "stir" the solvent, thus achieving mixing. This method effectively avoids impurities, mixes quickly, and yields the most ideal results. However, this method often requires manual operation, especially when mixing large quantities of solvent. It is not only time-consuming and labor-intensive, but also inefficient, and carries a high operational risk. If the container falls or leaks, it could cause serious physical and chemical harm to the human body.

[0003] Currently available mixing solutions that can replace manual labor typically use a motor to drive the container support and chamber, repeatedly starting and stopping to rotate the bottle. However, this solution is mainly applicable to small-capacity containers, and the acceleration and deceleration processes during motor start-up and stopping lead to internal wear on components. Furthermore, for mixing solvents in large-capacity containers, the inertia caused by the mass of the container and solvent itself can lead to deviations in the stationary position, resulting in further losses. Moreover, the acceleration and deceleration times of the motor are difficult to control, which is detrimental to solvent mixing. Therefore, for mixing solvents in large-capacity containers, the inverted method is often not feasible. A horizontal reciprocating mixing method is often used as an alternative, but this method requires more mixing cycles and longer mixing times, resulting in lower mixing efficiency. Utility Model Content

[0004] To address the above problems, this application provides a top-and-bottom tilting device for mixing and shaking large-capacity containers. It can be used to tilt and shake containers containing large-capacity, large-volume solvents to be mixed, which not only improves the mixing efficiency but also reduces wear between components.

[0032] In some solutions, the materials, layout, and connection methods of the above components can be reasonably replaced according to actual needs.

[0033] This application improves mixing efficiency and effect by combining a cam divider and a speed increaser in an up-and-down tilting device. Specifically, the cam divider controls the rotation and resting times of the mixing chamber, while the speed increaser adjusts the output angle of the cam divider, allowing the mixing chamber to rotate 180° vertically in a single rotation. This results in a resting period after each rotation, which can be controlled by the cam divider. This ensures sufficient gas flow through the solvent, effectively agitating it and preventing solvent stratification. The applicant further discovered that when the cam divider's drive angle is 120°, the cam divider divides the solvent into six equal parts, the speed increaser's ratio is 1:3, and the ratio of the mixing chamber's rotation and resting times is 1:2, the entire device achieves optimal solvent mixing. Furthermore, the use of the cam divider and speed increaser allows the DC motor to remain running throughout the mixing process, overcoming the problem of excessive wear caused by the constant starting and stopping of traditional motors. This increases the device's lifespan and reduces equipment costs.
