[0002] Shakers are commonly used laboratory equipment in the detection of fatty acid values ​​and mycotoxins in corn and rice. However, existing shakers have significant shortcomings in operation. Specifically, the test tube tray design of current shakers typically requires removing test tubes one by one from the rack and placing them individually into the tray's clamping mechanism. This operation is not only cumbersome but also time-consuming, especially when processing large numbers of samples, greatly reducing experimental efficiency. Furthermore, frequent removal and placement of test tubes may increase the risk of breakage, affecting the stability and safety of the experiment. More importantly, manual operation can lead to uneven clamping force, affecting the shaking effect and consequently the accuracy and repeatability of the test results.

[0036] Existing reciprocating shakers for detecting fatty acid values ​​and mycotoxins in corn and rice require individual removal and clamping of test tube trays from the rack, a cumbersome process that is difficult to digitize. This new solution rotates the test tube rack 90 degrees and places it directly onto the shaker tray. Pressing the start button automatically clamps the tray and begins shaking. After shaking, the tray automatically releases, allowing for easy removal of the rack. This device supports loading 36 or 45 test tubes at once, featuring automatic clamping / releasing, thus overcoming the pain points of traditional methods such as limited capacity (only one tube can be loaded at a time), low automation, high labor intensity, and low testing efficiency.

[0037] The following is combined with Figures 1 to 2 This application describes the tray device for a reciprocating oscillator and the reciprocating oscillator.

[0038] According to the first aspect of this application, the tray device for a reciprocating oscillator includes: a plurality of clamping plate assemblies, a connecting rod 6, a fixing rod 5, a guide post 4, a lead screw assembly 3, and a drive motor arranged sequentially. The clamping plate assembly includes a baffle 1 and a push plate 2 arranged opposite to each other, and both the baffle 1 and the push plate 2 are provided with guide holes. The connecting rod 6 connects to a plurality of baffles 1. The fixing rod 5 connects to a plurality of push plates 2. The guide post 4 passes through a plurality of guide holes. The lead screw assembly 3 is fixedly connected to the push plate 2 of one of the clamping plate assemblies, and the output shaft of the lead screw assembly 3 faces the baffle 1 of the corresponding clamping plate assembly. The lead screw assembly 3 is used to drive the push plate 2 to move relative to the baffle 1. The drive motor is connected to the lead screw assembly 3 to provide power.

[0039] According to the embodiments of this application, the tray device of the reciprocating oscillator, through the combined design of push plate 2 and baffle 1, drives push plate 2 to move relative to baffle 1 through screw assembly 3 to clamp and release test tubes, which significantly improves the processing efficiency of reciprocating oscillator.

[0040] Understandably, the clamping plate assembly consists of opposing baffles 1 and push plates 2. Both baffles 1 and push plates 2 are provided with guide holes to ensure the stability and accuracy of the clamping plate assembly during movement. A connecting rod 6 connects several baffles 1 to ensure that the baffles 1 move synchronously; a fixed rod 5 connects several push plates 2 to ensure that the push plates 2 move synchronously under the drive of the lead screw assembly 3. Guide posts 4 pass through the guide holes of the baffles 1 and push plates 2 to guide the movement direction of the clamping plate assembly, ensuring that the push plates 2 and baffles 1 remain stable and accurate during movement.

[0041] Baffle 1 and push plate 2 are arranged opposite each other to clamp or release the test tube. A lead screw assembly 3 is fixedly connected to the push plate 2 of one of the clamping plate assemblies, with its output shaft facing the corresponding baffle 1. The lead screw assembly 3 converts the power of the drive motor into linear motion through rotation, thereby driving the push plate 2 to move relative to the baffle 1, achieving clamping and releasing of the test tube. The drive motor is connected to the lead screw assembly 3, providing power and converting electrical energy into mechanical energy through rotation of the output shaft, driving the lead screw assembly 3 to move. Driven by the drive motor, the lead screw body of the lead screw assembly 3 continuously extends to the outermost baffle 1, causing the mounting block 7 and support rod 8 of the push plate 2 lead screw assembly 3 to move in opposite directions. Since several push plates 2 (three in the figure) are connected together by a fixing rod 5, the three push plates 2 move together, simultaneously completing the clamping. The releasing process is similar and will not be described further here.

[0042] The tray device of the reciprocating shaker in this embodiment of the application, through the combined design of push plate 2 and baffle 1, uses a lead screw assembly 3 to drive the push plate 2 to move relative to the baffle 1, thereby clamping and releasing the test tubes, significantly improving the processing efficiency of the reciprocating shaker. Furthermore, the design of the guide post 4 and guide hole enhances the stability of the device, reduces vibration and offset during movement, and improves the reliability and service life of the device. The automated design of the drive motor and lead screw assembly 3 simplifies the operation process and improves the convenience of the experiment.

[0043] According to one embodiment of this application, a control unit is included, which is electrically connected to a drive motor and is used to control the start, stop and direction of the drive motor.

[0044] The control unit can start or stop the drive motor according to experimental needs, ensuring that the movement of push plate 2 and baffle 1 proceeds as required during the experiment. For example, the motor can be started when the test tube needs to be clamped, and stopped after clamping is completed.

[0045] The control unit can control the direction of the drive motor, thereby adjusting the movement direction of the push plate 2 relative to the baffle 1. For example, it can control the motor to rotate forward when it is necessary to clamp the test tube, and control the motor to rotate in reverse when it is necessary to unlock the test tube.

[0046] According to one embodiment of this application, the drive motor is a stepper motor.

[0047] According to one embodiment of this application, the lead screw assembly 3 includes a lead screw body, a mounting block 7, and a support rod 8. The mounting block 7 is fixedly connected to the push plate 2 of one of the clamping plate assemblies, the support rod 8 connects the mounting block 7 and the drive motor, and the lead screw body is connected to the drive motor.

[0048] The lead screw body converts the power of the drive motor into linear motion through rotational motion, thereby driving the push plate 2 to move relative to the baffle 1, achieving clamping and unlocking of the test tube. The mounting block 7 is a fixing device used to connect the lead screw assembly 3 to the push plate 2 of the clamping plate assembly. The support rod 8 is a rigid connector used to connect the mounting block 7 and the drive motor.

[0049] According to one embodiment of this application, there are multiple fixing rods 5, with at least one fixing rod 5 disposed on the first side of the push plate 2 and at least one fixing rod 5 disposed on the second side of the push plate 2, the first side and the second side being opposite to each other.

[0050] The fixing rods 5 are distributed on the first and second sides of the push plate 2. This relative arrangement design ensures that the push plate 2 is subjected to uniform force during movement. By setting fixing rods 5 on both sides of the push plate 2, displacement or deformation of the push plate 2 caused by unilateral force can be avoided, thus improving the stability and reliability of the device.

[0051] The distributed design of multiple fixed rods 5 ensures that the push plate 2 can move synchronously under the drive of the lead screw assembly 3. This synchronization guarantees the overall coordination of the clamping plate assembly and improves the operating accuracy and efficiency of the device.

[0052] According to one embodiment of this application, there are multiple connecting rods 6, with at least one connecting rod 6 disposed on the first side of the baffle 1 and at least one connecting rod 6 disposed on the second side of the baffle 1, the first side and the second side being opposite to each other.

[0053] The connecting rods 6 are distributed on the first and second sides of the baffle 1. This relative arrangement design ensures that the baffle 1 is subjected to uniform force during movement. By setting the connecting rods 6 on both sides of the baffle 1, the displacement or deformation of the baffle 1 caused by unilateral force can be avoided, thereby improving the stability and reliability of the device.

[0054] According to one embodiment of this application, there are four guide posts 4, which are respectively located at the upper left corner, upper right corner, lower left corner and lower right corner of the clamping plate assembly, forming a rectangular distribution.

[0055] The four guide posts 4 are located at the upper left, upper right, lower left, and lower right corners of the clamping plate assembly, forming a rectangular layout. This distribution method can evenly support the clamping plate assembly, ensuring that it is subjected to uniform force during movement and avoiding displacement or tilting.

[0056] According to one embodiment of this application, the lead screw assembly 3 is disposed on the outermost clamping plate assembly.

[0057] Placing the lead screw assembly 3 on the outermost clamping plate assembly reduces the internal space occupied, making the overall layout of the device more reasonable and compact, and facilitating integration with other equipment or experimental platforms. For example, in a reciprocating oscillator, the tray device can be used more flexibly with other equipment of the reciprocating oscillator to improve experimental efficiency.

[0058] In addition, the lead screw assembly 3 is located on the outermost clamping plate assembly, which facilitates daily maintenance and replacement by operators.

[0059] According to one embodiment of this application, the clamping plate assembly includes an end plate and baffles 1 fixedly connected to the end plate. The end plate fixes the baffles 1 together, ensuring the overall stability of the clamping plate assembly during movement.

[0060] In addition, the end plate design makes it easier to install the tray device onto the base of the reciprocating oscillator.

[0061] A reciprocating oscillator according to an embodiment of this application includes:

[0062] Base;

[0063] The aforementioned tray device is mounted on a base;

[0064] A reciprocating oscillating motor is located on the base and connected to the pallet device to drive the pallet frame of the pallet device to perform reciprocating oscillating motion.

[0065] According to the reciprocating oscillator of this application, the combination design of baffle 1 and push plate 2, and the drive of push plate 2 relative to baffle 1 by screw assembly 3 to clamp and release test tubes, significantly improves the processing efficiency of reciprocating oscillator.

[0066] The base is the supporting structure for the oscillator, used to fix and support other components, and to ensure the stability and safety of the oscillator during operation. The tray device is connected to the base.

[0067] A reciprocating oscillating motor is connected to the tray assembly to drive the tray frame in reciprocating oscillating motion. The reciprocating oscillating motor can be an adjustable speed motor, allowing users to adjust the oscillation frequency and amplitude according to experimental requirements to achieve the best oscillation effect.

[0068] It should be noted that the reciprocating oscillator of this application has all the technical effects of the aforementioned tray device because it includes the tray device described above, and will not be repeated here.
