Description

TECHNICAL FIELD

[0001] The present application belongs to the field of flexible mixer structure, and particularly relates to a flexible mixer. BACKGROUND

[0002] The mixer is usually used to stir the mixture of mortar, slurry, cement, adhesive or paint, etc. When starting to stir, the stirring head has a large weight. When starting, the stirring head impacts the output shaft of the mixer with a reaction force due to the inertia of the stirring head. The reaction force acts on the gear of the reduction mechanism in the mixer, which damages the gear.

[0003] The technical solution provides a connecting piece between the stirring head and the main body of the mixer, which can eliminate or reduce the inertia impact when starting. SUMMARY

[0004] The purpose of the embodiment of the present application is to provide a flexible mixer. A connecting piece is arranged between the stirring head and the main body of the mixer. The connecting piece can be elastically deformed under stress. When transmitting torque, the connecting piece can be elastically deformed in the direction of increasing diameter, so as to absorb the inertia impact when the mixer starts, and thus the reduction gear in the mixer is protected.

[0005] The embodiment of the present application provides a flexible mixer, which comprises:

[0006] The mixer body, the stirring head and the connecting piece are connected. The connecting piece is arranged between the stirring head and the main body of the mixer and can transmit torque. The motor, the reduction assembly and the output shaft are arranged in the main body of the mixer. The motor rotates and outputs through the reduction gear assembly and then outputs to the output shaft. The output shaft is connected with the connecting piece, and the connecting piece transmits torque to the stirring head.

[0007] The spring shaft and the first pin are arranged on the output shaft. The spring shaft is coaxial with the output shaft. The first slot, the second slot and the notch are arranged on the connecting piece. The first pin is connected with the first slot. The first slot and the second slot are arranged on the two sides of the notch.

[0008] The second pin is arranged on the stirring head and connected with the second slot. The directions of the first slot and the second slot are opposite. The material of the connecting piece is spring steel.

[0009] The technical solution mainly arranges a connecting piece between the main body of the mixer and the stirring head, which plays a transition role. The connecting piece is elastically deformed in the direction of increasing diameter under the action of the large torque, so as to absorb the impact of the inertia of the stirring head when the mixer starts, protect the reduction gear in the main body of the mixer and prolong the service life of the mixer.

[0016] Embodiment

[0017] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0018] The flexible beater provided by the embodiments of the present application will be described in detail below with reference to the drawings, specific embodiments and application scenarios.

[0019] Reference Figures 1-4 , a flexible beater provided by the embodiments of the present application, as shown in Figure 1 may include:

[0020] a beater body 1, an output shaft 2, a connecting piece 3 and a beater head 4; wherein the beater head 4 is indirectly connected with the beater body 1; the connecting piece 3 is located between the beater head 4 and the beater body 1 and can transmit torque;

[0021] The blender main body 1 is provided with a motor, a speed reduction assembly and an output shaft 2. The motor rotates and outputs through the speed reduction assembly to the output shaft 2. The output shaft 2 is connected with the connecting piece 3. The output shaft 2 transmits the motor rotation to the connecting piece 3. The connecting piece 3 transmits the torque to the blender head 4. The connecting piece 3 plays a transitional role. When the output shaft 2 transmits the motor rotation to the connecting piece 3, due to the inertial effect of the blender head 4, the output shaft 2 will momentarily bear a large torque. At this time, the connecting piece 3 is subjected to the action of the large torque and elastically deforms in the direction of increasing diameter, thereby absorbing the impact of the inertia of the blender head 4 when the blender starts.

[0022] As shown in Figure 2 , the output shaft 2 is provided with a spring mandrel 21 and a first pin 22. The spring mandrel 21 is coaxial with the output shaft 2. A spring 5 is sleeved on the spring mandrel 21, so that the blender head 4 is away from the output shaft 2. The connecting piece 3 is provided with a first notch 32, a second notch 31 and a notch 33. The first pin 22 is connected with the first notch 32. The first pin 22 slides along the first notch 32 to the first recess 321. The blender head 4 is provided with a second pin 42. The second pin 42 is connected with the second notch 31. The second pin 42 slides along the second notch 31 to the second recess 311. The spring 5 is sleeved on the spring mandrel 21, so that the blender head 4 is away from the output shaft 2. The first pin 22 is stable in the first recess 321, so that the connecting piece 3 is stably connected with the output shaft 2. The second pin 42 is stable in the second recess 311, so that the connecting piece 3 is stably connected with the blender head 4.

[0023] As shown in Figure 4 , the notch 33 is to make the connecting piece 3 appear as C-shaped in the top view, so as to ensure that the connecting piece 3 will elastically deform when subjected to torque, thereby absorbing the inertial impact of the blender head 4. The first notch 32 and the second notch 31 are distributed on both sides of the notch 33. In this way, the connecting piece 3 is deformed under the action of the torque.

[0024] As shown in Figure 3 , the first notch 32 and the second notch 31 are opposite in direction. The connecting piece 3 is preferably a near-sight rotary body structure. In the side view, the opening direction of the first notch 32 and the second notch 31 should be towards one side of the central axis X. In this way, the torque can be better transmitted.

[0025] The material of the connecting piece 3 is spring steel with elasticity. The connecting piece 3 functions more like a leaf spring. It plays a role in buffering vibration and impact.

[0026] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims.
