[0025] Among them, the virus sampling tube centrifugal discharge machine 2 can be a medical centrifuge for virus sampling tubes from Xiangyi Group. This model is a special model optimized for virus sampling tubes, with a speed range of 3000-4500r / min. It is compatible with all specifications of virus sampling tubes from 3mL to 50mL, equipped with an adjustable fixed-angle rotor (or horizontal rotor), and integrates a discharge guide structure that connects with the "material guide trough" in the document to avoid messiness when transferring sampling tubes after centrifugation.
[0026] Working principle: 1. Preliminary preparation and equipment debugging 1. Basic Positioning and Inspection: The device is placed stably as a whole by the base 1. The virus sampling tube centrifugal discharge machine 2 on the top left of the base 1 has been pre-fixed to ensure that its discharge port is accurately connected with the inlet of the rear guide trough 4. The guide trough 4 is designed with an inclination, which allows the sampling tube to slide down naturally with the help of gravity. The end of the guide trough 4 extends to the top of the adjustment mechanism 3, laying the foundation for subsequent conveying connection. Before debugging, the operating status of the virus sampling tube centrifugal discharge machine 2 should be checked to ensure that the centrifugal separation component rotates smoothly. Check that there are no foreign objects blocking the inner wall of the guide trough 4 and that the trough is firmly fixed without loosening.
[0027] Parameter preset and calibration: Based on the specifications of the virus sampling tube to be collected and the size of the packaging device, key parameters are preset through the control system, including the lifting stroke of the electric push rod 306 and the speed of the servo motor 308. When calibrating the adjustment mechanism 3, the first mounting plate 303 is manually pushed, and the rolling state of the guide wheel 305 along the base 1 and the sliding state of the limit bar 309 in the first limit groove 302 are observed to ensure smooth movement without jamming. The electric push rod 306 is started to test the lifting accuracy of the third mounting plate 314. Through the cooperation of the limit rod 311 and the second limit groove 316, it is ensured that there is no radial offset during the lifting process.
[0028] 2. Fixing and positioning of packaging equipment Flexible fixed packaging device: The packaging device for collecting virus sampling tubes is placed on top of the third mounting plate 314 of the adjustment mechanism 3. It is fixed by the cooperation of the mounting rod 313 and the rubber strip 312. The mounting rods 313 on the front and rear sides of the third mounting plate 314 form opposing supports. The horizontally connected rubber strip 312 undergoes elastic deformation after the packaging device is placed. The deformation tension clamps and fixes the packaging device from both sides. The flexibility of the rubber strip can be adapted to packaging devices of different widths, while avoiding damage to the packaging device caused by rigid clamping, ensuring that the packaging device is stable and does not shift during the collection process.
[0029] Lifting and positioning adaptation height: When the electric push rod 306 is activated, its output shaft passes through the first mounting plate 303 and drives the third mounting plate 314 to lift and lower synchronously. The four limit rods 311 at the bottom of the third mounting plate 314 slide along the second limit groove 316 of the first mounting plate 303 to form a precise guide, ensuring that the third mounting plate 314 always remains in a horizontal state when lifting and lowering. When the height of the inlet of the packaging device is consistent with the height of the outlet at the end of the guide trough 4, the electric push rod 306 stops and locks its position to avoid impact damage to the sampling tube during its descent due to excessive height difference.
[0030] 3. Movement and positioning linkage of the adjustment mechanism The adjustment mechanism 3, through a linkage structure of "servo motor drive - threaded transmission - guide limit", enables the packaging device to move back and forth at a uniform speed, laying the foundation for uniform collection. Power transmission and motion drive: The second mounting plate 310 inside the groove 301 provides fixed support for the servo motor 308. After the servo motor 308 is started, its output shaft drives the threaded rod 315 to rotate through the coupling. The threaded rod 315 forms a threaded engagement with the bottom drive plate 307 of the first mounting plate 303, converting the rotational motion of the servo motor 308 into the linear motion of the drive plate 307, thereby driving the first mounting plate 303 to move back and forth along the groove 301. The speed of the servo motor 308 can be precisely controlled. By setting the speed through the control system, the moving speed of the first mounting plate 303 can be steplessly adjusted to adapt to different material discharge rate requirements.
[0031] Stable guidance and limiting protection: The mounting bracket 304 at the bottom of the first mounting plate 303 is rotatably connected to evenly distributed guide wheels 305. The bottom of the guide wheels 305 is in close contact with the bottom surface of the groove 301 of the base 1, which converts the sliding friction of the first mounting plate 303 into rolling friction, thereby reducing the moving resistance and improving the moving stability. At the same time, the first limiting grooves 302 on both sides of the groove 301 of the base 1 form a sliding fit with the limiting strips 309 fixed to the mounting bracket 304, which restricts the lateral displacement of the first mounting plate 303 and prevents it from tilting due to the shift of the center of gravity when it moves to the rear side of the base 1, ensuring that the packaging device is always aligned with the end outlet of the guide trough 4.
[0032] 4. Centrifugal discharge and uniform collection operation Centrifugal separation and material conveying: The virus sampling tubes to be centrifuged are placed into the inlet of the virus sampling tube centrifugal discharge machine 2. The virus sampling tube centrifugal discharge machine 2 is started, and its internal centrifugal components rotate at high speed. The centrifugal force separates the excess medium remaining on the surface and inside of the sampling tube. The separated medium is discharged and collected through a special channel. The virus sampling tubes that have completed centrifugation are pushed into the inlet of the material guide trough 4 one by one by the internal pushing mechanism of the virus sampling tube centrifugal discharge machine 2. They slide down the inner wall of the material guide trough 4 and are finally discharged from the end outlet, falling precisely into the packaging device on the adjustment mechanism 3 below.
[0033] Uniform collection is achieved through uniform movement: While the centrifugal discharge machine 2 continuously discharges virus sampling tubes, the servo motor 308 drives the threaded rod 315 to rotate at a preset speed, causing the first mounting plate 303 to drive the packaging device to move uniformly along the groove 301. When the front area of the packaging device is filled with sampling tubes, it moves to the middle area to continue collecting until the rear area is filled, achieving uniform distribution of sampling tubes inside the packaging device. During the movement, the dual guidance of the guide wheel 305 and the limiting strip 309 ensures that the packaging device is always aligned with the outlet of the guide trough 4, preventing the sampling tubes from falling. The locked lifting position of the electric push rod 306 ensures that the falling height of the sampling tubes is stable, further reducing the risk of breakage.
[0034] Operation Stop and Reset: When the packaging device is full or the virus sampling tube centrifugal discharge machine 2 has completed a single batch of discharge, the virus sampling tube centrifugal discharge machine 2 stops running. The servo motor 308 drives the first mounting plate 303 to reset to the initial position. The electric push rod 306 drives the third mounting plate 314 to rise to a convenient pick-up and drop height. The operator can untie the rubber strip 312 between the mounting rods 313 to take out the packaging device full of sampling tubes. After replacing the empty packaging device, the next round of operation can be started.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
