The rotating shaft 300 is provided with at least one movable with the rotating shaft 300 and movable up and down along the rotating shaft 300. The first agitating cutter 400. In the utility model, the first agitating cutter 400 rotates under the driving of the rotating shaft 300 to perform cutting and stirring operations; meanwhile, the first agitating cutter 400 moves along the rotating shaft 300 up and down with the stirring material during the rotating process, which is better. The cutting and stirring are carried out in contact with the stirring material, so that the cutting and stirring efficiency is greatly improved, the mixing time is effectively reduced, and the cutting and stirring are more uniform, finer and more thorough.

Specifically, referring to FIG. 2 and FIG. 3 , the shaft body of the rotating shaft 300 includes a large diameter end 310 at the upper portion and a small diameter end 320 at the lower portion, and the first agitating cutter 400 is slidably disposed at the small diameter end 320 . When the mixer is in operation, the first agitating blade 400 moves up and down along the small diameter end 320. When it moves to the top of the small diameter end 320, it is limited to the large diameter end 310 and cannot continue to move upward. The length of the small diameter end 320 is the first. A range of travel in which the cutter 400 is moved. By designing the small diameter ends 320 to different lengths, the first agitating cutters 400 can have different moving heights, so that different agitation effects can also be obtained. Specifically, the length of the small diameter end 320 can be set according to parameters such as the length of the rotating shaft 300 and the size of the agitating cup 200.

Specifically, referring to FIG. 2 and FIG. 3, in the embodiment, the first agitating cutter 400 is fixed on a first tool post 500, the first tool post 500 has a sleeve structure, and the small diameter end 320 of the rotating shaft 300 is sleeved. The center hole of the tool holder 500 passes through, and the small diameter end 320 is in clearance with the center hole of the first tool holder 500, that is, the first tool holder 500 can slide on the small diameter end 320 of the rotating shaft 300. When the rotating shaft 300 rotates, the first tool holder 500 can drive the first stirring tool 400 to move up along the small diameter end 320 under the action of the inertial force and the stirring material, and is subjected to gravity when moving to the top of the small diameter end 320. And automatically fall back.

Specifically, in the embodiment, the first agitating blade 400 includes two blades 410. The two blades 410 are oppositely fixed to the first tool holder 500, and the two blades 410 are disposed oppositely. In this embodiment, the two blades 410 are disposed opposite to each other such that the two blades 410 are balanced with respect to the first tool holder 500. Meanwhile, the two blades 410 are oppositely disposed to form a spiral-like structure, which is more advantageous when the blade 410 rotates. The contact between the mixing materials can better cut and stir. As can be seen in FIG. 2, the ends of each of the blades 410 are provided with connection holes 411, and the first tool holder 500 is provided with a slot (not shown) for inserting the ends of the blades 410 and The mounting hole 411 corresponding to the mounting hole (not shown) can be fixed to the first tool holder 500 by screwing a fastener such as a screw into the corresponding mounting hole and the connecting hole. It should be noted that, in this embodiment, the first tool post 500 can be omitted, and the two blades 410 of the first agitating tool 400 are integrated, and a clearance fit with the rotating shaft 300 is disposed between the two blades 410. Center hole.

Further, in this embodiment, the two blades 410 are disposed obliquely with respect to the rotating shaft 300, so that a certain inclination angle is formed between the two blades 410. When the rotation speed of the rotating shaft 300 is constant, the angle and the size between the two blades affect the speed of the first stirring tool 400 moving up and down along the rotating shaft 300, so the angle setting between the two blades 410 can be set according to actual needs.

Further, in this embodiment, the bottom of the rotating shaft 300 extends into the base 100, and a second tool holder 600 that can rotate with the rotating shaft 300 is disposed on the extending end, and the second tool holder 600 is provided with a second stirring. Tool 700. Here, the second agitating blade 700 is provided, and the agitating material falling into the bottom of the agitating cup 200 can be cut and stirred again.

Specifically, the second agitating blade 700 includes an annular connecting piece 710 and two blade sets 720 disposed around the annular connecting piece 710. One of the blade sets 720 includes two oppositely disposed blades 721 which are inclined upward, and the other blade set 720 includes two blades 722 that are oppositely disposed and that are each inclined downward. Thus, the upwardly inclined blade 721 is spaced apart from the downwardly inclined blade 722, and each blade also makes the agitation more uniform, finer, and more thorough as it rotates and rotates with the rotating shaft 300.

In this embodiment, a drive motor (not shown) is disposed in the base 100. The top end of the rotating shaft 300 is fixed to the top of the stirring cup 200. The bottom end of the rotating shaft 300 passes through a coupling 800 and the output shaft 900 of the motor. connection. In this embodiment, the drive motor is coupled to a control circuit (not shown) that controls the motor to accelerate or decelerate. The switching between acceleration and deceleration can be realized by internal program implementation or control components. In this embodiment, when the first agitating tool 400 moves up to the highest position along the small-diameter end 320 of the rotating shaft 300, the motor output shaft 900 decelerates, and the rotating shaft 300 is driven to rotate downward. At this time, the cutting force of the first agitating cutter 400 is weakened. When the first agitating cutter 400 moves to the lowest position of the small-diameter end 320, the motor output shaft 900 accelerates, and the rotating shaft 300 accelerates and rotates. At this time, the first one is moved downward by the self-gravity action and the stirring material. The agitating cutter 400 is again moved up to the highest position along the small-diameter end 320 of the rotating shaft 300, so that the upper and lower movements of the first agitating cutter 400 are continuously completed, and the cutting of the stirring material is completed during the continuous upper and lower movements. Stir work.

In summary, in the present invention, the first agitating cutter 400 rotates under the driving of the rotating shaft 300 to perform cutting and stirring operations; meanwhile, the first agitating cutter 400 moves up and down along the rotating shaft 300 during the rotating process, which is better. The cutting and stirring are carried out in contact with the stirring material, so that the cutting and stirring efficiency is greatly improved, the mixing time is effectively reduced, and the cutting and stirring are more uniform, finer and more thorough.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the present invention. Within the scope of protection.
