DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "arranged," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0049] like Figure 1-4As shown, a centrifugal self-rotating mixer includes: a base 1, a frame 2, a fixing part 3, a motor 4, an eccentric part 5, a mounting plate 6, a first restraining part 7, a slope hole 8, a second restraining part 9, and a stirring rod 10. The base 1 is set on the ground, the frame 2 is installed on the base 1, the fixing part 3 is set on one side of the dotted frame 2, the motor 4 is installed above the fixing part 3, the output end of the motor 4 is passed through the top of the fixing part 3, the eccentric part 5 is installed at the output end of the motor 4, and one end of the mounting plate 6 is installed on the fixing part 3. The first constraint part 7 is located below the fixing part 3, the sloped hole 8 is opened above the first constraint part 7, and the second constraint part 9 is located below the first constraint part 7. The top of the stirring rod 10 is connected with the eccentric part 5. The connection between the eccentric part 5 and the stirring rod 10 can assist the stirring rod 10 in centrifugal rotation. The bottom end of the stirring rod 10 passes through the sloped hole 8 and the second constraint part 9. In short, the first constraint part 7 and the second constraint part 9 limit the range of movement of the stirring rod 10, so that the stirring rod 10 applies more uniform force during centrifugal revolution, thereby improving the stability of the equipment. At the same time, the stirring rod 10 is close to the slope of the sloped hole 8 when rotating, so that the stirring rod 10 can be tilted and rotated. The tilted revolution can effectively avoid cleaning dead corners and prevent particle accumulation.

[0050] like Figure 2-3 As shown, in order to ensure the smooth operation of the device and to make the stirring rod 10 rotate to form a convection effect, a first universal hole 11 is opened at the bottom of the first restraining member 7, a second universal hole 12 is opened at the top of the second restraining member 9, a first universal joint 13 is fixedly sleeved on the rod body of the stirring rod 10, the first universal joint 13 is in contact with the first universal hole 11, and a second universal joint 14 is fixedly sleeved on the rod body of the stirring rod 10, the second universal joint 14 is in contact with the second universal hole 12. The coordinated arrangement of the universal joint and the universal hole can assist the stirring rod 10 in tilting and revolving while reducing the friction generated when the stirring rod 10 rotates, making the stirring rod 10 less prone to wear.

[0051] In this embodiment, Figure 4As shown, the transmission rod 15 is located on one side of the fixing member 3, the top end of the transmission rod 15 is passed through the fixing member 3, the transmission wheel 16 is installed on the transmission rod 15, one end of the belt 17 is sleeved on the eccentric wheel, and the other end of the belt 17 is sleeved on the transmission wheel 16 to form power transmission. When the motor 4 rotates, the transmission wheel 16 will be driven by the eccentric wheel through the belt 17 to rotate. The first support member 18 is installed on one side of the first constraint member 7, and the second support member 19 is installed on one side of the second constraint member 9. The first support member 18 and the second support member 19 ensure The transmission rod 15 will not fall off. The second support member 19 is located below the first support member 18. The main gear 20 is installed on the transmission rod 15, and the driven gear 21 is installed on the stirring rod 10. The driven gear 21 is located between the first universal joint 13 and the second universal joint 14. The stirring paddle is installed at the bottom of the stirring rod 10. The driven gear 21 is engaged with the main gear 20. Once the transmission rod 15 rotates, it will drive the main gear 20, and the main gear 20 will drive the driven gear 21 to rotate. The rotation of the driven gear 21 means that the stirring rod 10 has generated self-rotation. The self-rotation of the stirring rod 10 will increase the contact area between the stirring paddle 22 and the liquid, and the coordinated use of self-rotation and revolution will produce a convection effect, accelerating the mixing reaction speed.

[0052] It should be noted that the centrifugal self-rotating mixer designed by the present invention is started when the motor 4 is used. The output end of the motor 4 rotates to drive the eccentric 5, and the eccentric 5 drives the stirring rod 10 to rotate centrifugally close to the slope of the ramp hole 8. The rotation of the eccentric 5 will also drive the belt 17 to transmit power. The belt 17 transmits power to the transmission wheel 16. The rotation of the transmission wheel 16 drives the transmission rod 15 to rotate. The rotation of the transmission rod 15 drives the main gear 20 of its rod body. The main gear 20 rotates to drive the driven gear 21 meshed with it. The driven gear 21 rotates to drive the stirring rod 10 to rotate. The rotation of the stirring rod 10 drives the stirring paddle 22 to complete the rotation. The rotation of the stirring rod 10 plus the centrifugal revolution will accelerate the mixing efficiency. At this point, the use process ends.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
