Description

Technical Field

[0001] The invention relates to the technical field of material mixing, and in particular to a mechanical resonance material mixing device and a mixing process thereof. Background Art

[0002] Resonance mixer is a kind of mixing equipment that uses the resonance principle to mix materials. It is widely used in material mixing in various fields. The working principle of resonance mixer is based on the resonance principle, that is, when the excitation frequency of the driving force on the object is the same as the natural frequency of the mixing system, the mixing system will resonate. Near the resonance band, the vibration amplitude of the material will be amplified, generating a large vibration acceleration, thereby achieving a mixing effect.

[0003] The resonance mixer is mainly composed of a vibration device, a placement table, a container, a spring and a damper. The placement table and the weight of the container, the spring and the damper together constitute a resonance system. The vibration device is used to generate mechanical vibrations, and the resonance system is used to make the material inside the container vibrate due to resonance, thereby achieving uniform mixing of the materials.

[0004] However, the dynamic stability of existing resonant mixers is poor. Changes in the weight of the material will cause changes in the natural frequency of the resonant system, and changes in the natural frequency will cause the resonance point of the resonant system to shift, so that the energy of the mechanical vibration cannot be effectively amplified, which in turn causes the vibration energy of the material to be weakened, making it impossible to mix the material evenly.

[0029] Reference Figure 1 and Figure 2, a material discharge assembly 3 is movably provided on the top of the mounting frame 2, and the material discharge assembly 3 includes a material discharge platform 31, a first guide column 32, a material cup 33 and a pressing member 34. The material discharge platform 31 is rotatably connected to the first connecting portion 542. In this embodiment, a plurality of first guide columns 32 are provided, and the plurality of first guide columns 32 are fixedly installed on the bottom surface of the material discharge platform 31, and the plurality of first guide columns 32 are slidably connected to the mounting frame 2. The material cup 33 is placed in the material discharge platform 31. In this embodiment, the pressing member 34 includes a material pressure cover 341 and a connecting screw 342. The connecting screw 342 is threadedly connected to the material discharge platform 31. The material pressure cover 341 is fixedly connected to one end of the connecting screw 342 close to the material cup 33, and the material pressure cover 341 is located directly above the material cup 33.

[0030] Reference Figure 1 and Figure 2 When mixing the materials, the operator first uses a weighing device to weigh the weight of the material cup 33, and after placing the material to be mixed into the material cup 33, the operator again uses a weighing device to weigh the total weight of the material cup 33 and the material placed therein, thereby determining the weight of the placed material. The material cup 33 with the material placed therein is placed at a fixed position on the material discharge platform 31, and the operator rotates the connecting screw 342, so that the connecting screw 342 drives the material pressing cover 341 to move downward, until the material pressing cover 341 presses and covers the material cup 33, thereby helping to prevent relative displacement between the material cup 33 and the material discharge platform 31, thereby helping to improve the stability of the material cup 33 placed on the material discharge platform 31, and at the same time helping to prevent the material placed inside the material cup 33 from falling out.

[0031] Reference Figure 1 and Figure 2 , a counterweight assembly 4 is movably provided at the bottom of the mounting frame 2. In this embodiment, the counterweight assembly 4 includes a counterweight platform 41, a counterweight sheet 43 and a plurality of second guide columns 42. The counterweight platform 41 is rotatably connected to the second connecting portion 544, and the weight of the counterweight platform 41 is the same as that of the material discharge assembly 3. The plurality of second guide columns 42 are fixedly mounted on the top surface of the counterweight platform 41, and the plurality of second guide columns 42 are all slidably connected to the mounting frame 2. The counterweight sheet 43 is detachably mounted on the counterweight platform 41, and the weight of the counterweight sheet 43 is the same as the weight of the material placed in the material discharge assembly 3. In other embodiments, the counterweight assembly 4 can also be configured to have the same structure as the above-mentioned material discharge assembly 3.

[0032] Reference Figure 2 and Figure 3When the material cup 33 is placed, a weight plate 43 with the same weight as the placed material is selected and installed on the weight platform 41. The operator sets the frequency parameters of the drive motor 51, and starts the drive motor 51 after the setting is completed. The output end of the drive motor 51 drives the rotating shaft 52 to rotate synchronously through the transmission belt 53. The rotating shaft 52 drives the first eccentric part 541 and the second eccentric part 543 to rotate synchronously while rotating. The first eccentric part 541 drives the material discharging platform 31 to reciprocate linear motion through the first connecting part 542 while rotating. The second eccentric part 543 drives the weight platform 41 to reciprocate linear motion through the second connecting part 544 while rotating. The movement process of the material discharging platform 31 and the weight platform 41 is synchronously reversed, which helps to use the resonance principle to drive the vibration of the material inside the material cup 33, and then helps to achieve uniform mixing of the materials.

[0033] In the above process, placing a counterweight plate 43 with the same weight as the material inside the material cup 33 on the counterweight platform 41 helps to balance the weight with the material, thereby helping to prevent the change of the natural frequency of the mixing device, and further helping to improve the mixing effect of materials of different weights, helping to improve the applicability of the mixing device.

[0034] The embodiment of the present application also discloses a mechanical resonance material mixing process based on the above mixing device, comprising the following steps: Step 1: The operator first uses a weighing device to weigh the weight of the material cup 33, and after placing the material to be mixed into the material cup 33, the operator again uses the weighing device to weigh the total weight of the material cup 33 and the material placed therein, thereby determining the weight of the placed material.

[0035] Step 2: The operator places the material cup 33 with the material placed in a fixed position on the discharge table 31, and rotates the connecting screw 342, so that the connecting screw 342 drives the material cover 341 to move downward until the material cover 341 presses and covers the material cup 33, which helps prevent relative displacement between the material cup 33 and the discharge table 31, thereby helping to improve the stability of the material cup 33 placed on the discharge table 31, and at the same time helps to prevent the material placed inside the material cup 33 from falling out.

[0036] Step three: The operator selects a counterweight plate 43 of equal weight to the material placed in the material cup 33 and installs it on the counterweight platform 41, which helps to achieve counterweight balance, thereby helping the counterweight component 4 and the discharge component 3 to generate forces of equal magnitude and opposite directions during movement, which in turn helps to offset the forces generated by the two on the rotating shaft 52, thereby helping to reduce the vibration of the mounting frame 2.

[0037] Step 4: The operator sets the frequency parameters of the drive motor 51. After the setting is completed, the drive motor 51 is started. The output end of the drive motor 51 drives the rotating shaft 52 to rotate synchronously through the transmission belt 53. The rotating shaft 52 drives the first eccentric part 541 and the second eccentric part 543 to rotate synchronously while rotating. The first eccentric part 541 drives the discharge table 31 to perform reciprocating linear motion through the first connecting part 542 while rotating. The second eccentric part 543 drives the counterweight table 41 to perform reciprocating linear motion through the second connecting part 544 while rotating. The movement process of the discharge table 31 and the counterweight table 41 is synchronously reversed, which helps to use the resonance principle to drive the vibration of the material inside the material cup 33, and then helps to achieve uniform mixing of the materials.

[0038] Step 5: The operator turns off the drive motor 51 and rotates the connecting screw 342 in the opposite direction, so that the connecting screw 342 drives the material cover 341 to move upward until the material cover 341 releases the pressure on the material cup 33, and then removes the material cup 33 from the discharge table 31, and pours the mixed material in the material cup 33 into a container for storage.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
