[0043] The embodiments of the utility model are described in detail below in combination with the drawings.

[0044] As Figures 1 to 3 shown, the utility model embodiment provides a centrifuge positioning drive mechanism, and the positioning drive mechanism includes centrifugal motor 1, first transmission part, positioning drive part 2, second transmission part and positioning detection assembly.

[0045] Among them, centrifugal motor 1 is arranged to drive centrifuge high-speed rotation to carry out centrifugation.

[0046] One end of the first transmission part is connected with the output end of the centrifugal motor 1, and the other end is connected with the centrifugal main shaft 6, and the kinetic energy of the centrifugal motor 1 is transmitted to the centrifugal main shaft 6 of the centrifuge through the first transmission part, so as to drive the centrifugal main shaft 6 to rotate and drive the rotary drum 61 connected therewith to rotate.

[0047] Positioning drive part 2 is arranged to drive the centrifugal main shaft 6 to rotate at low speed to realize the positioning of the rotary drum 61 and / or the material frame assembly.

[0048] One end of the second transmission member is connected with the output end of the positioning driving member 2, and the other end is connected with the first transmission member. The kinetic energy of the positioning driving member 2 is transmitted through the second transmission member and the first transmission member to drive the centrifugal main shaft 6 to rotate. The second transmission member is connected with the first transmission member without being directly connected to the centrifugal main shaft 6, which can effectively simplify the connection structure of the centrifugal main shaft 6, avoid interference of multiple transmission members to the centrifugal main shaft 6, and make the centrifugal main shaft 6 operate more stably and reliably.

[0049] The positioning detection assembly is installed on the centrifugal main shaft 6 and rotates with the centrifugal main shaft 6 to correspond to the drum 61 of the centrifugal machine and / or the material frame assembly matched with the drum 61, and is used to map the position of the drum and / or the material frame assembly. Whether the drum 61 and / or the material frame assembly is rotated to the required position can be determined through detection of the positioning detection assembly.

[0050] The positioning driving member 2 includes a lifting connecting rod 21 which can be adjusted up and down. The lifting connecting rod 21 can be connected or disconnected with the second transmission member by adjusting the lifting connecting rod 21. When the lifting connecting rod 21 is connected with the second transmission member, the centrifugal main shaft 6 can be driven by the positioning driving member 2 to rotate at a low speed to position the drum 61 and / or the material frame assembly. When the lifting connecting rod 21 is disconnected with the second transmission member, the positioning driving member 2 will not affect the centrifugal main shaft 6. The lifting connecting rod 21 should be disconnected with the second transmission member when the centrifugal motor 1 drives the centrifugal operation. The lifting connecting rod 21 can effectively avoid interference of the positioning driving member 2 to the normal centrifugal operation, and avoid the influence of misoperation, and is more safe and reliable. The positioning driving member 2 is used to drive the centrifugal main shaft 6 to position the drum 61 and / or the material frame assembly only when the centrifugal motor 1 stops running.

[0051] Preferably, the positioning driving member 2 is a hand-driven member. Specifically, the positioning driving member 2 further includes a hand lever 22, a first bevel gear 23, a second bevel gear 24, a worm 25 and a worm wheel 26.

The second bevel gear 24 is coaxially and fixedly arranged on the worm 25. The second bevel gear 24 drives the worm 25 to rotate synchronously. The worm 25 is in meshing transmission with the worm wheel 26. The worm wheel 26 is coaxially sleeved on the vertically arranged lifting connecting rod 21 through a sleeve 261. The lifting connecting rod 21 can move axially to adjust up and down relative to the sleeve 261, and is circumferentially limited relative to the sleeve 261 (i.e. the sleeve 261 and the lifting connecting rod 21 will rotate synchronously). The worm wheel 26 can drive the sleeve 261 and the lifting connecting rod 21 to rotate.

[0052] Further, the positioning driving member 2 further comprises a housing 20, a hand lever 22 is rotatably arranged in the housing 20 through a first bearing 221, one end of the hand lever 22 is connected with the first bevel gear 23 in the housing 20, and the other end of the hand lever 22 is provided with a handle outside the housing 20. The first bevel gear 23, the second bevel gear 24, the worm 25, the turbine 26 and the sleeve 261 are arranged in the housing 20, wherein the worm 25 and the sleeve 261 are rotatably arranged in the housing 20 through a second bearing 262 at two ends thereof.

[0053] In an embodiment, the lifting connecting rod 21 is a lead screw, and the positioning driving member 2 is further provided with a hand wheel 27, the hand wheel 27 is adapted to be sleeved on the lifting connecting rod 21 and is rotatably arranged on the housing 20, and rotating the hand wheel 27 can drive the lifting connecting rod 21 to adjust the lifting, so as to realize the connection or disconnection with the second transmission member.

[0054] Further, the lifting connecting rod 21 is provided with a guide key 211 extending in the axial direction, and the sleeve 261 is provided with a guide groove matched with the guide key 211, so that the axial up-down adjustment of the lifting connecting rod 21 in the sleeve 261 is realized through the matching and limiting of the guide key 211 and the guide groove, and when the lifting connecting rod 21 is lowered, the guide key 211 is matched and engaged with the guide groove, so that the circumferential limiting of the lifting connecting rod 21 relative to the sleeve 261 is realized, and at this time, the lifting connecting rod 21 can rotate together with the sleeve 261 under the driving of the worm wheel 26.

[0055] In an embodiment, the first transmission member comprises a first pulley 31, a second pulley 32 and a first belt 33, the first pulley 33 is coaxially fixed to the lower part of the centrifugal main shaft 6, the second pulley 32 is coaxially arranged on the output shaft of the centrifugal motor 1, and the first belt 33 connects the first pulley 31 and the second pulley 32 for transmission.

[0056] The second transmission member comprises a third pulley 41, a fourth pulley 42 and a second belt 43. The third pulley 41 is rotatably arranged on the frame 413 through a third bearing 411, and the third pulley 41 is provided with a clamping groove 412 coaxially connected thereto, the clamping groove 412 is matched and connected with the lower end of the lifting connecting rod 21 for circumferential limiting, and the lifting connecting rod 21 can drive the third pulley 41 to rotate through the clamping groove 412. The fourth pulley 42 is transmissionally connected with the second pulley 32, preferably coaxially fixed; and the second belt 43 connects the third pulley 41 and the fourth pulley 42 for transmission.

[0057] In an embodiment, the position detection assembly comprises a corresponding index plate 51 and a signal detection switch 52. The index plate 51 is coaxially fixedly installed on the centrifugal main shaft 6, preferably on the first pulley 31, and rotates synchronously with the centrifugal main shaft 6. Meanwhile, the index plate 51 corresponds to the position of the rotating drum 61 and / or the material frame assembly. The signal detection switch 52 is fixedly installed on the bottom of the centrifuge. The signal detection switch 52 is used to detect each divided position of the index plate 51. When the index plate 51 rotates, a divided position corresponds to the signal detection switch 52, and a position detection signal can be sent, indicating that the rotating drum 61 and / or the material frame assembly rotates to a desired position. When the index plate 51 continues to rotate to the next divided position corresponding to the signal detection switch 52, the next position detection signal can be sent, indicating that the rotating drum 61 and / or the material frame assembly rotates to the next desired position. That is, the position of the rotating drum 61 and / or the material frame assembly is determined by the change of the rotating position of the index plate 51, so as to realize accurate positioning of the rotating drum 61 and / or the material frame assembly.

[0058] As shown in Figure 4 , preferably, the material frame assembly comprises a material frame 62 and a plurality of material frames 63. The material frame 62 is fixedly installed in the rotating drum 61 and rotates synchronously with the rotating drum 61. The inner circumferential surface of the material frame 62 is evenly and separately provided with a plurality of separated frames 621. The material frames 63 are detachably and correspondingly installed in the separated frames 621 and can be put into and taken out from the upper part of the separated frames 621. The number of the divided positions of the index plate 51 and the installation position are set to correspond to the separated frames 621 of the material frame 62. Preferably, the number of the divided positions of the index plate 51 is equal to the number of the separated frames 621 of the material frame 62, and each divided position of the index plate 51 corresponds to the position of each separated frame 621 of the material frame 62 fixedly installed in the rotating drum 61. Therefore, the positioning of each separated frame 621 of the material frame 62 can be realized by detecting the index plate 51 by the signal detection switch 52, which facilitates the processing of the material frames 63 and the material in each separated frame 621, such as loading and unloading operations.

[0059] Further, as shown in Figure 3 , preferably, the cover of the centrifuge is provided with a small-sized loading and unloading port 7. The loading and unloading port 7 corresponds to the position of the separated frames 621 of the material frame 62 fixedly installed in the rotating drum 61, and the size of the loading and unloading port 7 is correspondingly matched with the size of the material frames 63, slightly larger than the size of the material frames 63, so that the material frames 63 can vertically pass through the loading and unloading port 7. That is, when the rotating drum 61 rotates to make the separated frames 621 correspond to the loading and unloading port 7, the material frames 63 can be loaded into or taken out of the separated frames 621 through the loading and unloading port 7. Thus, the loading and unloading of the material can be realized by only opening the small-sized loading and unloading port 7 without opening the entire cover, which is especially suitable for high-temperature or low-temperature centrifuges, and can reduce the loss of heat energy or cold energy caused by unloading and loading between two centrifugations.

[0060] Working process: after high-speed centrifugation driven by centrifugal motor 1, the centrifugal motor 1 is turned off; after the centrifugal spindle 6 and the drum 61 stop rotating, the hand wheel 27 is rotated to adjust the lifting connecting rod 21 to move downward and be clamped with the clamping groove 412 on the third pulley 41, so that the positioning driving part 2 is in transmission connection with the second transmission part; then, the handle is rotated to rotate the hand lever 22, and sequentially drive the first bevel gear 23, the second bevel gear 24, the worm 25, the worm wheel 26 and the lifting connecting rod 21 to rotate, and then drive the centrifugal spindle 6, the drum 61, the material frame 62 and the material frame 63 on the centrifugal spindle 6 to rotate through the second transmission part and the first transmission part; at this time, the index plate 51 rotates synchronously with the centrifugal spindle 6, when the signal detection switch 52 and the equal division part on the index plate 51 correspond to send a detection signal, the driving hand lever 22 is stopped, at this time, the material frame 62 rotates to the appropriate position, and the separation frame 621 corresponds to the loading and unloading port 7; the material frame 63 can be taken out by a mechanical lifting arm and the like to unload, and then new centrifugation material is loaded; after the first material taking and loading is completed, the hand lever 22 is continuously rotated to rotate the material frame 62 to the next separation frame 621 corresponding to the loading and unloading port 7, and the material taking and unloading operation is sequentially performed; after the material frame 63 in the separation frame 621 is completed, the loading and unloading port 7 is closed, the hand wheel 27 is rotated to adjust the lifting connecting rod 21 to move upward and be separated from the clamping groove 412 on the third pulley 41, and then the centrifugal motor 2 can be restarted for the next round of centrifugation operation.
