Detailed Description of the Invention

[0018] The following will combine with the attached drawings Figures 1 to 4 to describe the present utility model in detail.

[0019] A liftable planetary mixer of the present utility model includes a base 1. A pillar 11 is provided on the base 1. A liftable connecting plate 2 is provided on the pillar 11. A first lifting device 12 for driving the connecting plate 2 to move is provided at the top of the pillar 11. One end of the connecting plate 2 is provided with a stirrer 3, and the stirrer 3 can be driven by the first lifting device 12 to lift, so as to adjust the height of the stirrer 3. The stirrer 3 is provided with a fixed sleeve 31, the fixed sleeve 31 is fixedly connected with the connecting plate 2, a movable sleeve 32 is arranged in the fixed sleeve 31, an internal gear 321 is arranged on the inner wall of the movable sleeve 32, a rotating device 33 is arranged in the fixed sleeve 31, the rotating device 33 is provided with a connecting shaft 331 extending into the interior of the movable sleeve 32, a bushing 322 movably connected with the connecting shaft 331 is arranged at the top of the movable sleeve 32, the connecting shaft 331 is provided with three rotatable rotating shafts 332, stirring paddles 333 are arranged at the ends of the rotating shafts 332, and a transmission gear 334 that can cooperate with the internal gear 321 is arranged on the rotating shaft 332. In this structure, when the rotating device 33 drives the connecting shaft 331 to rotate, the stirring paddles 333 will not only rotate following the connecting shaft 331, but also rotate by themselves because the transmission gear 334 cooperates with the internal gear 321. Compared with the existing single-axis stirring or double planetary stirring on the market, the planetary mixer of the present utility model greatly improves the stirring quality and has a high stirring intensity. A limiting groove 311 is arranged on the fixed sleeve 31, the rotating device 33 is provided with a limiting block 34 that cooperates with the limiting groove 311, and a second lifting device 21 for driving the limiting block 34 to move up and down along the limiting groove 311 is arranged on the connecting plate 2. Among them, there are at least two limiting grooves 311. After the limiting block 34 is clamped in the limiting groove 311, the rotating device 33 can be fixed to prevent the rotating device 33 from being affected by the torque reaction force. When the second lifting device 21 drives the limiting block 34 to lift, the rotating device 33 moves up and down synchronously. Through the bushing 322, the movable sleeve 32 also moves up and down with the rotating device 33. This structure can adjust the height position of the stirring paddles 333 without changing the height of the stirrer 3, which is convenient for adjusting the stirring depth of the stirring paddles 333 in the stirring barrel and can be applicable to stirring barrels of different heights, with a wide application range.

[0020] It includes a screw rod 22 movably connected to a connecting plate 2. A threaded hole 341 threadedly connected to the screw rod 22 is provided on the limiting block 34. The other end of the screw rod 22 passes through the connecting plate 2 and is provided with a first synchronous pulley 23. The second lifting device 21 is provided with a second synchronous pulley 24. A transmission belt 25 is provided between the first synchronous pulley 23 and the second synchronous pulley 24. In this solution, the stirring paddle 333 is finally driven to move up and down through the transmission of the screw rod 22. The lifting process is stable and has high precision. The height of the stirring paddle 333 can be adjusted during the operation of the stirrer 3, which is convenient to use.

[0021] The connecting plate 2 is provided with a guiding column 26 extending upward. A guiding hole 342 that can be sleeved with the guiding column 26 is provided on the limiting block 34. There are two guiding columns 26 and guiding holes 342 respectively, which are respectively arranged on both sides of the threaded hole 341, making the lifting of the limiting block 34 more stable and the structural stability high.

[0022] The inner wall of the fixed sleeve 31 is provided with a positioning strip 312, and the positioning strip 312 is parallel to the connecting shaft 331. The outer wall of the movable sleeve 32 is provided with a positioning groove 323 that cooperates with the positioning strip 312. When the stirring paddle 333 is performing stirring operations, the torque will be conducted to the movable sleeve 32 through the transmission gear 334. By the clamping of the positioning strip 312 and the positioning groove 323, the position of the movable sleeve 32 can be fixed to prevent the movable sleeve 32 from rotating.

[0023] The bottom of the movable sleeve 32 is provided with a bottom plate 35, and a fixing hole 351 for fixing the rotating shaft 332 is provided on the bottom plate 35. After the movable sleeve 32 descends, it is easy to touch the stirring material in the stirring barrel. The bottom plate 35 can seal the bottom of the movable sleeve 32 and fix the rotating shaft 332 to prevent the stirring paddle 333 from shaking.

[0024] A driving device is provided inside the base 1, which can drive the support column 11 to rotate. In this solution, the driving device is controlled by numerical control devices such as a controller and a master control device to drive the stirrer 3 to move its position, which is convenient for sequentially stirring multiple stirring barrels, with a wide range of usage directions and high functionality.

[0025] The first lifting device 12 is a hydraulic cylinder. The weight of the stirrer 3 is relatively high, and accidents such as overheating and shaking of the motor are likely to occur with ordinary motor drives. The hydraulic cylinder has the characteristics of high stability and large power. In the solution of the present utility model, the first lifting device 12 uses a hydraulic cylinder to drive the stirrer 3 to lift.

[0026] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
