DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0034] The principle of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0035] The utility model proposes Figure 1-9The centrifugal agitator shown comprises a housing 1 with a mixing chamber 11, a sealed mixing barrel 2, a servo motor 3 and a clamp 4. The clamp 4 is rotatably mounted in the mixing chamber 11 and used to fix the mixing barrel 2. The servo motor 3 is used to drive the clamp 4 to rotate. The clamp 4 comprises a slide 41, a first clamping plate 42 and a second clamping plate 43 relatively slidably mounted on the slide 41, and a screw rod 44 and a clamp motor 45 for driving the first clamping plate 42 and the second clamping plate 43 to slide. This embodiment is used to stir and mix high-viscosity tobacco oil raw materials. The tobacco oil raw materials are contained in the mixing barrel 2. After the mixing barrel 2 is placed between the first clamping plate 42 and the second clamping plate 43, the clamp motor 45 is started, and the clamp motor 45 drives the screw rod 44 to rotate. The first clamping plate 42 and the second clamping plate 43, which are connected to the screw rod 44, move relatively along the slide 41 to clamp the mixing barrel 2 to prevent it from loosening during rotation. After stirring, the clamp motor 45 rotates in the reverse direction, and the first clamping plate 42 and the second clamping plate 43 are separated from each other, so that the stirring barrel 2 can be taken out smoothly.

[0036] The clamp 4 is in a rotating state when working, and it is difficult to connect an external wire. Therefore, the clamp motor 45 is fixedly installed on the side wall of the mixing chamber 11. The front end of the clamp motor 45 is provided with a telescopic coupling 46, which is connected or disconnected with the screw rod 44 through the telescopic coupling 46. The screw rod 44 is installed in the slide groove 41, and a connector 441 is provided at the end of the screw rod 44. When the spacing between the first clamping disk 42 and the second clamping disk 43 needs to be changed, the connector 441 is rotated by the servo motor 3 to face the telescopic coupling 46, and the telescopic coupling 46 actively extends to connect with the connector 441.

[0037] The telescopic coupling 46 is located directly below the mixing chamber 11 and is composed of an electromagnet 461 and a telescopic sleeve 462. The electromagnet 461 is disc-shaped, with a sleeve hole in the middle, and is sleeved on the front part of the body of the clamp motor 45. The telescopic sleeve 462 is slidably sleeved on the motor shaft of the clamp motor 45. The middle part of the telescopic sleeve 462 is a polygonal through-shaft hole 463, and the front end of the motor shaft is provided with a slider 464. The shape of the slider 464 matches the through-shaft hole 463 and is slidably installed in the through-shaft hole 463. A magnetic disc 465 is provided at one end of the telescopic sleeve 462 close to the electromagnet 461, and a limit hole 466 connected to the through-shaft hole 463 is provided in the middle of the magnetic disc 465.

[0038] When the electromagnet 461 is powered on, the magnetism of the side opposite to the magnetic disc 465 is the same. When the mixing barrel 2 needs to be clamped, the clamp 4 is rotated to the position where the connector 441 is directly opposite to the telescopic sleeve 462 through the control of the servo motor 3, and then the electromagnet 461 is powered on, and the magnetic disc 465 and the telescopic sleeve 462 connected to the magnetic disc 465 are pushed upward by magnetic force, so that the connector 441 enters the through shaft hole 463 at the front end of the telescopic sleeve 462, and then the clamp motor 45 is started, and the screw rod is rotated synchronously through the telescopic sleeve 462. The screw rod 44 rotates to drive the first clamping disk 42 and the second clamping disk 43 to move relative to each other to clamp the mixing barrel 2. After clamping, the clamp motor 45 and the electromagnet 461 are powered off. After the electromagnet 461 loses its magnetic force, the telescopic sleeve 462 is retracted by gravity and separated from the screw rod 44 to avoid affecting the rotation of the clamp 4.

[0039] In this embodiment, a support shaft 47 extends backward from the middle of the slide slot 41, and the support shaft 47 is rotatably mounted on the housing 1 through a bearing. A large flywheel 31 is sleeved on the rear of the support shaft 47, and a small flywheel 32 is sleeved on the rotating shaft of the servo motor 3. The large flywheel 31 and the small flywheel 32 are connected by a hinge or a belt drive.

[0040] In this embodiment, the first clamping plate 42 is provided with a groove 48 that matches the shape of the bottom of the mixing barrel 2, and the second clamping plate 43 is provided with a groove 48 that matches the shape of the top of the mixing barrel 2. In addition, the top of the mixing barrel 2 has an inverted trapezoidal limiting groove 21, and the second clamping plate 43 is provided with a limiting block 431 that matches the limiting groove 21. The groove 48 can better restrain the top and bottom of the mixing barrel 2. The barrel cover 22 of the mixing barrel 2 is located in the limiting groove 21. When clamped, the limiting block 431 can not only further limit the displacement of the mixing barrel 2, but also press the barrel cover 22 to prevent it from accidentally opening due to excessive pressure when rotating.

[0041] In this embodiment, the housing 1 is further divided into an equipment compartment 12, which is used to install equipment such as the servo motor 3 and the fixture motor 45. The equipment compartment 12 is located below the mixing compartment 11, and a drawer-type water collection tank 5 is also provided in the equipment compartment 12. The wall of the mixing compartment 11 is in a cylindrical shape, and a drain port 13 is provided at the bottom of the cylinder. The drain port 13 is located directly above the drawer-type water collection tank 5. If the mixing barrel 2 leaks accidentally, the leaked tobacco oil raw material can enter the drawer-type water collection tank 5 through the drain port 13. When there are stains in the mixing compartment 11, the mixing compartment 11 can also be rinsed.

[0042] In this embodiment, the centrifugal agitator also includes a split base 6, which is surrounded by a rim 61, and the centrifugal agitator is placed inside the rim 61. The mixing barrel 2 is likely to cause the centrifugal agitator to vibrate when rotating, and a weight block 62 is provided inside the split base 6, which can increase the mass of the centrifugal agitator and reduce the impact of vibration. When the centrifugal agitator needs to be transported, the centrifugal agitator can be transported separately from the split base 6 to reduce the difficulty of transportation. A plurality of shock-absorbing suction cups 63 are arranged at the bottom of the split base 6, and the split base 6 can be fixed to the ground by the shock-absorbing suction cups 63. In addition, the shock-absorbing suction cups 63 can also play a buffering role, reducing the noise generated by the centrifugal agitator hitting the floor when vibrating.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
