[0024] This invention provides an improved device for non-contact speed regulation of centrifuge equipment, the working principle of which is as follows; When using this device, first place it in the work area, and then connect it to an external power source to provide the necessary electrical energy for the device to work. When this device is needed, the controller 14 can be used to control the drive motor 12 to start via the data cable 13. The drive motor spindle 21 drives the transmission plate 29 to rotate synchronously. When the drive motor spindle 21 rotates, it can drive the magnetic drum 25 and the device connected to it to rotate. The transmission pin 210 on the transmission plate 29 interacts with the slide plate 211, pushing the magnetic drum 25 and the components connected to it to rotate together. Since there is an air gap 5 between the magnetic drum 25 and the permanent magnet rotor 34, the rotating permanent magnetic field of the magnetic drum 25 cuts the magnetic field lines in the magnetic drum 25 when it rotates, generating a strong eddy current. This eddy current induces a magnetic field that interacts with the permanent magnetic field, thus "dragging" the permanent magnet rotor 34 to rotate synchronously. The permanent magnet rotor 34 then drives the output shaft 35 to rotate and drive the external device, realizing the transmission of power from the drive motor 12 to the output shaft 35. When the magnetic drum 25 rotates, it generates heat, which is absorbed and transferred to the arc-shaped heat sink 27 by the heat conduction ring 26. When the arc-shaped heat sink 27 rotates, it can accelerate the dissipation of the heat transferred by the heat conduction ring 26. Furthermore, the hot air can be dissipated through the dustproof and breathable mesh 23, preventing the magnetic drum 25 from being affected by overheating.

[0025] Example 2: Please see Figs. 1-6 The present invention provides a device for non-contact speed regulation of centrifuge equipment. Compared with Embodiment 1, this embodiment further includes: an adjustment component 4 comprising an upper slide 41, an upper dust cover 42, a slide rod 43, an adjustment dual-axis motor 44, a gear shaft 45, a hypoid gear 46, a lead screw 47, a lower slide 48, and a lower dust cover 49. The front end of the upper slide 41 is slidably connected to the upper end of the reinforcing fixing plate 36 via a slide groove 38, and the front end of the upper slide 41 is slidably connected to the upper end of the first fixing plate 11 via a slide groove 38. The rear end of the upper slide 41 is fixedly connected to the upper side of the front end of the second fixing plate 31. The upper slide 41 provides support for the upper adjustment structure, ensuring structural stability during adjustment. The rear end of the upper dust cover 42 is fixedly connected to the upper front end of the second fixing plate 31, the front end of the upper dust cover 42 is fixedly connected to the front end of the upper slide 41, the middle part of the upper dust cover 42 is fixedly connected to the front and rear ends of the first fixing plate 11 and the reinforcing fixing plate 36, and the slide rod 43 is fixedly connected inside the upper slide 41. The front end of the slide rod 43 is slidably connected to the upper end of the first fixing plate 11 through the slide groove 38, and the middle part of the slide rod 43 is slidably connected to the upper end of the reinforcing fixing plate 36 through the slide groove 38.

[0026] The dual-axis motor 44 is fixedly connected to the lower front end of the second fixed plate 31. The gear shaft 45 is fixedly connected to the left and right ends of the dual-axis motor 44. After the dual-axis motor 44 is started, it can drive the gear shaft 45 to rotate. When the gear shaft 45 rotates, it can drive the hypoid gear 46 to rotate. The hypoid gear 46 is rotatably connected to the lower front end of the second fixed plate 31. The front tooth surface of the hypoid gear 46 meshes with the gear shaft 45. The rear end of the lead screw 47 is fixedly connected to the middle of the hypoid gear 46. The rear end of the lead screw 47 is rotatably connected to the lower front end of the second fixed plate 31. The front end of the lead screw 47 is rotatably connected to the lower slide 48. The front end of the lead screw 47 is threadedly connected to the lead screw nut 17.

[0027] The rear end of the lower slide 48 is fixedly connected to the lower end of the reinforcing fixing plate 36, and the front end of the lower slide 48 is slidably connected to the lower end of the first fixing plate 11 through the slide groove 38. The front end of the lower dust cover 49 is fixedly connected to the front end of the lower slide 48, and the rear end of the lower dust cover 49 is fixedly connected to the reinforcing fixing plate 36. The lower dust cover 49 is fitted around the outer ring of the lower slide 48 and connected to the fixing plate, preventing dust from entering the lower sliding parts and protecting the core adjusting parts of the lead screw 47 and lead screw nut 17. The middle part of the lower dust cover 49 is fixedly connected to the first fixing plate 11, and the lower dust cover 49 is located on the outer ring of the lower slide 48.

[0028] In this embodiment: When adjustments to this device are required, a speed adjustment signal can be sent to the dual-axis motor 44 via the controller 14. After the dual-axis motor 44 is started, it can drive the gear shafts 45 at both ends to rotate. The gear shafts 45 mesh with the hypoid gears 46, driving the hypoid gears 46 to rotate, which in turn causes the lead screw 47 fixed to it to rotate synchronously. Since the lead screw 47 is threadedly connected to the lead screw nut 17 on the first fixed plate 11, the rotation of the lead screw 47 will push the first fixed plate 11 to slide back and forth along the first slide bar 15. When the first fixed plate 11 slides, it drives the magnetically conductive drum 25 to move synchronously, changing the size of the air gap 5 between the magnetically conductive drum 25 and the permanent magnet rotor 34. If it is necessary to increase the output speed... Adjusting the dual-axis motor 44 to drive the lead screw 47 to rotate causes the first fixed plate 11 to move towards the magnetically guided drum 25. Through the cooperation of the transmission plate 29, the transmission pin 210 and the sliding plate 211, the magnetically guided drum 25 can slide on the main shaft 21 of the drive motor, making the air gap 5 smaller. The electromagnetic coupling between the magnetically guided drum 25 and the permanent magnet rotor 34 is enhanced, and the speed of the permanent magnet rotor 34 increases. This increases the speed of the centrifuge through the output shaft 35. If it is necessary to reduce the output speed, the dual-axis motor 44 is adjusted to rotate in the opposite direction, causing the lead screw 47 to rotate in the opposite direction. The first fixed plate 11 moves away from the transmission assembly 3, the air gap 5 increases, the electromagnetic coupling weakens, the speed of the permanent magnet rotor 34 decreases, and the speed of the centrifuge decreases accordingly. During the adjustment process, the upper slide 41 and the lower slide 48 slide along the slide groove 38, cooperating with the first slide rod 15 and the slide sleeve 16 to ensure that the first fixed plate 11 slides smoothly; the upper dust cover 42 and the lower dust cover 49 prevent dust from entering the sliding parts and avoid affecting the adjustment accuracy.

[0029] This invention provides an improved device for non-contact speed regulation of centrifuge equipment. Through the coordinated action of the drive control component 1, rotor assembly 2, transmission component 3, adjustment component 4, and air gap 5, flexible speed adjustment and stable operation are achieved. The air gap 5 is located between the rotor assembly 2 and the transmission component 3. The size of the air gap 5 is changed by the adjustment component 4, thereby adjusting the magnetic coupling strength and achieving stepless speed regulation, avoiding the impact and wear of traditional mechanical speed regulation. The controller 13 and drive motor 12 in the drive control component 1 work together to ensure speed regulation accuracy and response speed. The rotor assembly 2 uses a heat-conducting coil 26 and an arc-shaped heat sink 27 to effectively dissipate heat and improve equipment durability. The dustproof and breathable mesh 23 and dustproof cover design reduce dust intrusion and simplify maintenance. The transmission component 3 transmits torque through the electromagnetic induction of the permanent magnet rotor 34 and the magnetically conductive drum 25, resulting in a compact structure and high efficiency. The overall device features a wide speed range, stable operation, and good heat dissipation.
