Description

Technical Field

[0001] The present invention relates to a single-drive multi-motion energy-saving centrifugal oscillation device, which relates to an oscillation device capable of realizing reciprocating oscillation of a test tube in an experiment, and belongs to the technical field of laboratory equipment. In particular, it relates to an oscillation device having two groups of oscillating components symmetrically arranged on both sides of a driving component. Both groups of oscillating components are connected to the driving component. The driving component drives the oscillating components to move, and further drives the test tube to oscillate reciprocally, which can realize efficient oscillation of the test tube and induce the liquid in the test tube to form complex centrifugal motion. The oscillation device is particularly suitable for samples with high viscosity or difficult to mix. Background Art

[0002] In the laboratory, the test tube oscillator is an important experimental equipment used to promote liquid mixing, dissolution or homogenization. The liquid in the test tube usually needs to be shaken to achieve sufficient physical and chemical reactions. However, when dealing with viscous liquids, high-density particle suspensions or samples that need to be quickly homogenized, oscillation in a single direction can easily lead to uneven mixing or inefficiency. Currently, the common test tube oscillation devices on the market are mainly divided into two types: one is a rotary oscillator, and the other is a linear reciprocating oscillator. The rotary oscillator drives the tray or fixed frame to rotate by a motor. The rotation in a single direction can easily form vortices, which will cause uneven flow inside the liquid and affect the mixing effect. The linear reciprocating oscillator drives the tray to move up and down or left and right by an eccentric wheel or a linear motor. This type of equipment is usually suitable for low-speed and long-distance oscillation needs, but its performance is limited when rapid mixing is required, especially when dealing with viscous or high-density samples, and it cannot achieve efficient mixing effects.

[0003] Announcement No. CN222715350U discloses a microbial inoculant mixing device, including an inlet and a lifting mechanism arranged outside the inlet, the lifting mechanism including a working component and a lifting component, the working component including a first motor, and a first motor is arranged outside the inlet, the outer wall of the first motor is fixedly connected to a limit plate, and by setting a sliding disk, the first motor fixed on the inner wall of the limit plate is operated, so that the first motor drives the rotating shaft and the gear to rotate, and the gear causes the meshing circular rack to move, so that the circular rack slides in the sliding groove opened by the sliding column, thereby achieving the purpose of lifting, driving the top plate, connecting rod and sliding disk to slide in the groove of the mixing barrel, and accelerating the outflow speed of the inoculant. The device can only achieve linear motion in a single direction, and the oscillation mixing efficiency is low, and it is not suitable for processing viscous or high-density samples. Summary of the Invention

[0004] In order to improve the above situation, the present invention provides a single-drive multi-motion energy-saving centrifugal oscillation device with two sets of swing components symmetrically placed on both sides of the driving component. The two sets of swing components are connected to the driving component. The driving component drives the swing components to move, and further drives the test tube to swing back and forth, which can achieve efficient swinging of the test tube and induce the liquid in the test tube to form complex centrifugal motion. It is particularly suitable for an oscillation device for samples with high viscosity or difficult to mix.

[0012] The difference between this embodiment and embodiment 1 is that a shock-absorbing pad (31) is provided on the bottom surface of the bottom plate (9), and the edge of the shock-absorbing pad (31) is flush with the edge of the bottom plate (9). When the device is running, the device will generate a certain amount of vibration.

Example 3

[0013] The difference between this embodiment and embodiment 1 is that a rubber strip (32) is provided on the inner wall of the socket (8). The flexible material of the rubber strip (32) can absorb high-frequency vibration energy during the oscillation process, reducing the direct collision between the test tube and the hard inner wall of the test socket (8), thereby reducing the test tube breakage rate; the contact surface between the rubber strip (32) and the outer wall of the test tube generates static friction, preventing the test tube from sliding or detaching from the test tube socket (8) due to inertia during the swinging process, thereby ensuring the stability of the oscillation; the damping characteristics of the rubber can suppress the noise generated by the collision between the test tube and the socket (8), thereby reducing the operating noise of the equipment.

[0014] The first sliding rod (15) and the second sliding rod (17) both adopt a hollow structure design, which can significantly reduce the weight of the sliding rod by reducing the amount of material used, thereby improving movement efficiency and reducing energy consumption; The ends of the first sliding rod (15) and the second sliding rod (17) are provided with grooves, and the corresponding positions where the limiting plate (16) is connected to the sliding rod are provided with protrusions. The limiting plate (16) is fixed by embedding the protrusions into the grooves of the sliding rods, which can make the connection between the limiting plate (16) and the sliding rods more stable, effectively prevent the limiting plate (16) from loosening or falling off, and play a positioning role for the positions of the first sliding rod (15) and the second sliding rod (17), thereby preventing the sliding rods from deviating; The end of the rotating wobble plate (22) connected to the gear shaft (23) is cylindrical with a larger area, and the end connected to the first connecting column (2) is cylindrical with a smaller area. The design of connecting the two ends through a smooth transition area can optimize the power transmission performance of the rotating wobble plate. The end with a larger area ensures a greater torque bearing capacity and higher transmission efficiency through close cooperation with the gear shaft (23). The end with a smaller area precisely cooperates with the first connecting column (2) to achieve more flexible movement and avoid stress concentration. An annular groove is provided on the outer side of the connection between the T-shaped sleeve (14) and the connecting rod, and the inner surface of the groove is polished to provide a clear socket reference for the first connecting rod (3) and the second connecting rod (4), thereby improving the operating accuracy of the equipment, reducing the friction coefficient, and improving the rotation flexibility; The second connecting rod (4) and the third connecting rod (18) and one end connected to the T-shaped sleeve (14) are designed as an annular structure matching the groove, which can reduce the risk of loosening due to vibration or impact and improve the reliability of the equipment under high frequency or heavy load conditions; The purpose is to achieve efficient swinging of the test tube and induce the liquid in the test tube to form complex centrifugal motion, which is especially suitable for samples with high viscosity or difficult to mix.
