Description

Technical Field

[0001] This invention relates to the field of Boeing mixing machine technology, and more particularly to a Boeing mixing machine for general dental materials. Background Technology

[0002] In the process of dental treatment and restoration, the formulation of high-precision dental materials (such as impression materials, resin cement, dental ceramic slurry, etc.) is a crucial step. These materials are often extremely sensitive to air bubbles. The presence of air bubbles will directly lead to the formation of cavities or weak points inside the material, which will seriously affect its mechanical properties, dimensional stability and the precision and strength of the final restoration.

[0003] Currently, the industry commonly uses mechanical stirring as the mixing method. This involves using a motor-driven stirring paddle or blade to rotate and scrape within a material container, utilizing mechanical shearing force to mix different components. However, the existing mechanical stirring devices and methods have significant technical drawbacks. First, during the high-speed rotation and cutting of materials, the mechanical blades easily trap air into the material, generating a large number of bubbles. This is a fatal flaw for materials that are sensitive to bubbles. Second, the mechanical moving parts (such as motors and gears) generate continuous and significant noise during operation, affecting the treatment environment. Furthermore, the mixing effect of mechanical stirring mainly occurs at the macroscopic flow level. For high-performance materials that require highly uniform distribution of components at the microscopic or even molecular scale, the mixing uniformity is limited, and uneven shearing force may lead to differences in local material properties. The root cause of these problems lies in the fact that traditional mixing methods rely on macroscopic, non-uniform mechanical force fields.

[0004] Therefore, when used in high-precision dental material mixing scenarios that are sensitive to air bubbles, it is inconvenient to achieve bubble-free, low-noise, and highly uniform mixing. This invention can design a universal dental material mixing machine. When using this universal dental material mixing machine, the operator opens the door and places the container holding the dental material into the lifting cylinder inside the mixing chamber. Then, the lifting mechanism is activated to raise the container, so that the corresponding mixing head is completely immersed in the material. The lifting mechanism is then stopped and the lifting cylinder is kept in position. After closing the door, the ultrasonic mixing mechanism is activated through the control module, and the vibration energy is transmitted to the interior of the material through the mixing head to achieve molecular-level uniform mixing, which is more efficient than traditional mechanical stirring. This device achieves bubble-free, low-noise, and highly uniform mixing by using ultrasonic vibration mixing, and is especially suitable for high-precision dental materials that are sensitive to air bubbles. Summary of the Invention

[0005] Currently, the industry generally uses mechanical stirring as the mixing method. During the process of high-speed rotation and cutting of materials, mechanical blades can easily trap air into the material, generating a large number of bubbles. This is a fatal flaw for the aforementioned bubble-sensitive materials. Therefore, when used in high-precision dental material mixing scenarios that are sensitive to bubbles, it is inconvenient to achieve bubble-free, low-noise, and highly uniform mixing.

[0006] The technical solution of the present invention is as follows: a universal dental material mixing machine, including a chassis, a door connected to the front of the chassis, and a mixing chamber fixedly installed in the inner cavity of the chassis. The inner cavity of the mixing chamber is provided with two sets of lifting cylinders and two sets of mixing rods. Two sets of ultrasonic mixing mechanisms are provided at the top of the mixing chamber, and two sets of lifting mechanisms are provided at the bottom of the mixing chamber. A control module is provided inside the chassis.

[0007] Preferably, when using this type of universal dental material mixing machine, the operator opens the door, places the container holding the dental material into the lifting cylinder inside the mixing chamber, then activates the lifting mechanism to raise the container, so that the corresponding mixing head is completely immersed in the material. The lifting mechanism is then stopped and the lifting cylinder is kept in position. After closing the door, the ultrasonic mixing mechanism is activated through the control module, and the vibration energy is transmitted to the material through the mixing head to achieve molecular-level uniform mixing, which is more efficient than traditional mechanical stirring. This device achieves high uniformity mixing with no bubbles and low noise by using ultrasonic vibration mixing, and is especially suitable for high-precision dental materials that are sensitive to bubbles.

[0008] Preferably, the lifting cylinder and the mixing rod are set in a one-to-one correspondence, and the mixing rod consists of a connecting rod and a mixing head.

[0009] Preferably, the ultrasonic mixing mechanism includes an ultrasonic generator, an ultrasonic transducer, and an amplitude transformer. The ultrasonic generator is installed in the inner cavity of the housing, and two sets of ultrasonic transducers are installed on the top of the mixing chamber. An amplitude transformer is connected to the bottom of the ultrasonic transducer, and the connecting rod is fixedly connected to the amplitude transformer by a bolt structure.

[0010] Preferably, the lifting mechanism includes electrically controlled lifting rods, and two sets of electrically controlled lifting rods are fixedly installed at the bottom of the mixing silo, with the telescopic ends of the electrically controlled lifting rods fixedly connected to the bottom of the lifting cylinder.

[0011] Preferably, the lifting mechanism also includes guide columns and limit rings. Multiple sets of guide columns are fixedly installed on the outer circumferential surface of the lifting cylinder, and limit rings are fixedly installed at the lower end of the guide columns.

[0012] Preferably, the guide columns are installed through and slidably at the bottom of the mixing chamber, and multiple sets of guide columns are distributed in a circumferential array.

[0013] Preferably, an elastic rubber buffer pad is fixedly installed on the bottom wall of the inner cavity of the lifting cylinder, and a memory foam ring layer is fixedly installed on the side wall of the inner cavity of the lifting cylinder.

[0014] Preferably, the control module includes a frequency adjustment module, a power supply module, an operation panel, and a control circuit board. Two sets of frequency adjustment modules are installed on the top of the mixing silo, an operation panel is installed on the front outer wall of the chassis, and a control circuit board and a power supply module are installed in the inner cavity of the chassis.

[0015] As a preferred option, the mixing head has multiple structural forms: the bottom surface of the mixing head is flat, the outer circumferential surface of the mixing head is threaded, and the bottom surface of the mixing head is threaded.

[0016] Preferably, a cooling fan is installed on the rear side of the chassis, and a temperature sensor is installed inside the chassis cavity.

[0017] The beneficial effects of this invention are: 1. When using this type of universal dental material mixing machine, the operator opens the door and places the container holding the dental material into the lifting cylinder inside the mixing chamber. Then, the lifting mechanism is activated to raise the container, so that the corresponding mixing head is completely immersed in the material. The lifting mechanism is then stopped and the lifting cylinder is kept in position. After closing the door, the ultrasonic mixing mechanism is activated through the control module, which transmits vibration energy to the material through the mixing head to achieve molecular-level uniform mixing. This is more efficient than traditional mechanical mixing. By using ultrasonic vibration mixing, this device achieves bubble-free, low-noise, and highly uniform mixing, which is especially suitable for high-precision dental materials that are sensitive to bubbles.

[0018] 2. The mixing head is designed with three structural forms to adapt to different dental materials: the flat bottom surface is suitable for low viscosity resin-based composite materials (such as flowable resins), which achieve rapid and uniform diffusion through planar vibration; the threaded outer surface is suitable for medium viscosity glass ionomer cement, where the thread structure enhances the turbulence effect and improves mixing efficiency; and the threaded bottom surface is suitable for high viscosity silicone rubber, where the thread protrusions increase local shear force and promote the dispersion of viscous materials.

[0019] With a wide frequency range of 20kHz–60kHz adjustable design and a variety of interchangeable mixing heads, the equipment can adapt to the mixing needs of a variety of dental materials, from low-viscosity temporary adhesives to high-viscosity silicone rubber impression materials and resin-based filling materials, making it highly versatile.

[0020] Ultrasonic mixing technology improves efficiency by more than 40% compared to traditional mechanical mixing. It achieves "multi-purpose" through a wide frequency adjustable design of 20kHz~60kHz: the low frequency band (20-30kHz) is suitable for high viscosity materials (such as silicone rubber), and the high frequency band (40-60kHz) is suitable for low viscosity materials (such as molding materials), effectively reducing bubble generation (bubble rate reduced to below 0.5%) and noise pollution (operating noise ≤65dB).

[0021] 3. During the mixing process, the temperature sensor monitors the temperature inside the chassis in real time. When the temperature exceeds the preset threshold, the cooling fan is triggered to start forced convection cooling.

[0022] The equipment adopts a closed chassis design, and with the help of temperature sensors and heat dissipation fans, it realizes intelligent temperature control to ensure that the working temperature is stable at 25±1℃.

[0023] 4. The mechanical limiting structure of the guide column and the limiting ring ensures a lifting accuracy of ≤0.1mm. The memory foam ring layer and the elastic rubber buffer pad form a dual shock absorption system, making the equipment vibration amplitude ≤5μm and extending the service life of mechanical parts.

[0024] 5. The modular structure supports independent or collaborative operation of two workstations, improving the work efficiency of clinical or technical rooms. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1 Please see Figure 1 and Figure 2 The present invention provides an embodiment of a universal dental material mixing machine, comprising a housing 1, a door 2 connected to the front of the housing 1, and a mixing chamber 3 fixedly disposed in the inner cavity of the housing 1. The inner cavity of the mixing chamber 3 is provided with two sets of lifting cylinders 4 and two sets of mixing rods. The top of the mixing chamber 3 is provided with two sets of ultrasonic mixing mechanisms, and the bottom of the mixing chamber 3 is provided with two sets of lifting mechanisms. The housing 1 is provided with a control module.

[0029] Please see Figure 2 and Figure 7 The lifting cylinder 4 is set one-to-one with the mixing rod. The mixing rod consists of a connecting rod 5 and a mixing head 6. The modular structure supports independent or collaborative operation of two workstations, which improves the work efficiency of the clinical or technical room. The ultrasonic mixing mechanism includes an ultrasonic generator 7, an ultrasonic transducer 8 and an amplitude transformer 9. The ultrasonic generator 7 is set in the inner cavity of the housing 1. Two sets of ultrasonic transducers 8 are set on the top of the mixing chamber 3. The bottom of the ultrasonic transducer 8 is connected to the amplitude transformer 9. The connecting rod 5 is fixedly connected to the amplitude transformer 9 by a bolt structure. The working frequency (20kHz~60kHz adjustable) and output power of the ultrasonic generator 7: The digital signal processor generates a specific waveform signal, which drives the ultrasonic transducer 8 to work through the power amplifier. The ultrasonic transducer 8 converts the high-frequency electrical signal into mechanical vibration and amplifies the amplitude through the amplitude transformer 9. Finally, it is transmitted to the interior of the material by the mixing head 6 at the lower end of the connecting rod 5 to achieve molecular-level uniform mixing.

[0030] Please see Figure 3 and Figure 6The lifting mechanism includes an electrically controlled lifting rod 10. Two sets of electrically controlled lifting rods 10 are fixedly installed at the bottom of the mixing chamber 3. The telescopic ends of the electrically controlled lifting rods 10 are fixedly connected to the bottom of the lifting cylinder 4. After the electrically controlled lifting rods 10 are started, their telescopic ends push the lifting cylinder 4 to rise vertically. The lifting mechanism also includes guide columns 11 and limit rings 12. Multiple sets of guide columns 11 are fixedly installed on the outer circumferential surface of the lifting cylinder 4. Limit rings 12 are fixedly installed at the lower end of the guide columns 11. When the limit rings 12 at the lower end of the multiple sets of guide columns 11 contact the bottom surface of the platform, a mechanical limit is formed to ensure that the lifting stroke is accurate and controllable. The electrically controlled lifting rod 10 stops and maintains its position until the container rises to the point where the mixing head 6 at the lower end of the mixing rod is completely immersed in the material. The guide columns 11 are slidably installed at the bottom of the mixing chamber 3. The multiple sets of guide columns 11 are distributed in a circular array. The circular array of guide columns 11 fixed to the outer wall of the lifting cylinder 4 slides along the guide holes inside the platform.

[0031] Please see Figure 5 and Figure 6 An elastic rubber buffer pad 13 is fixedly installed on the bottom wall of the inner cavity of the lifting cylinder 4, and a memory foam ring layer 14 is fixedly installed on the side wall of the inner cavity of the lifting cylinder 4. When the container containing dental materials is placed into the lifting cylinder 4 at the top of the mixing chamber 3 platform, the memory foam ring layer 14 on the inner wall of the lifting cylinder 4 forms a buffer and fixing structure by elastically deforming and wrapping the outer wall of the container. The elastic rubber buffer pad 13 on the bottom wall of the inner cavity provides vertical shock absorption support.

[0032] Please see Figure 3 and Figure 4 The control module includes a frequency adjustment module 15, a power supply module 16, an operation panel 17, and a control circuit board 18. Two sets of frequency adjustment modules 15 are installed on the top of the mixing chamber 3. An operation panel 17 is installed on the front outer wall of the casing 1. The control circuit board 18 and the power supply module 16 are installed in the inner cavity of the casing 1. The ultrasonic mixing system is activated by the operation panel 17. The microprocessor in the control circuit board 18 retrieves the pre-stored parameters from the storage module according to the selected material type and automatically configures the working frequency (adjustable from 20kHz to 60kHz) and output power of the ultrasonic generator 7.

[0033] When using this type of universal dental material mixing machine, the universal dental material mixing machine achieves efficient and precise mixing through a modular intelligent control system. Its working principle is as follows: After the operator opens the front door 2 of the machine box 1, the container containing dental materials is placed into the lifting cylinder 4 at the top of the mixing chamber 3 platform. At this time, the memory foam ring layer 14 on the inner wall of the lifting cylinder 4 forms a buffer and fixing structure by elastically deforming and wrapping the outer wall of the container. The elastic rubber buffer pad 13 on the bottom wall of the inner cavity provides vertical shock absorption support.

[0034] After the electric lifting rod 10 is started, its telescopic end pushes the lifting cylinder 4 to rise vertically. The circumferential array of guide columns 11 fixed to the outer wall of the lifting cylinder 4 slides along the guide hole inside the platform. When the limiting rings 12 at the lower end of the multiple sets of guide columns 11 contact the bottom surface of the platform, a mechanical limit is formed to ensure that the lifting stroke is accurate and controllable until the container rises to the point where the mixing head 6 at the lower end of the mixing rod is completely immersed in the material, the electric lifting rod 10 stops and maintains its position.

[0035] After closing the door 2, the ultrasonic mixing system is activated through the operation panel 17. The microprocessor in the control circuit board 18 retrieves the pre-stored parameters from the storage module according to the selected material type and automatically configures the working frequency (adjustable from 20kHz to 60kHz) and output power of the ultrasonic generator 7. The digital signal processor generates a specific waveform signal, which drives the ultrasonic transducer 8 to work through the power amplifier. The ultrasonic transducer 8 converts the high-frequency electrical signal into mechanical vibration and amplifies the amplitude through the amplitude transformer 9. Finally, the vibration is transmitted to the interior of the material through the mixing head 6 at the lower end of the connecting rod 5 to achieve molecular-level uniform mixing.

[0036] Two independent ultrasonic mixing mechanisms support synchronous / asynchronous operation modes, and can simultaneously process two materials with different properties or perform multi-parameter verification. The power module 16 supplies power to each sensor and actuator. The operation panel 17 provides a human-machine interface. The frequency adjustment module 15 includes a digital signal processor and a power amplifier. The control circuit board 18 integrates a microprocessor to realize parameter control and logic operation.

[0037] The mechanical limiting structure of the guide column 11 and the limiting ring 12 ensures that the lifting accuracy is ≤0.1mm. The memory foam ring layer 14 and the elastic rubber buffer pad 13 form a dual shock absorption system, which makes the vibration amplitude of the equipment ≤5μm and extends the service life of mechanical parts.

[0038] The control panel 17 features a touchscreen design, supporting visual adjustment of parameters and real-time monitoring of the mixing process, thus improving ease of operation.

[0039] This device achieves high-uniformity mixing with no bubbles and low noise by using ultrasonic vibration, making it particularly suitable for high-precision dental materials that are sensitive to bubbles.

[0040] By integrating material parameter preset, temperature monitoring and automatic heat dissipation functions into the intelligent control system, the repeatability and ease of operation of the mixing process are improved.

[0041] The modular structure supports independent or collaborative work at two workstations, improving the efficiency of clinical or technical laboratories.

[0042] The ultrasonic generator 7 and the ultrasonic transducer 8 are two key components of the ultrasonic system: Ultrasonic generator 7: It is responsible for generating a signal with the same frequency as the transducer and driving the transducer to work through power amplification, thereby generating ultrasonic vibration.

[0043] Ultrasonic transducer 8: It is the core component of the entire ultrasonic system, responsible for converting high-frequency high-voltage signals into mechanical vibration energy. The performance of the transducer directly affects the output effect of the ultrasonic waves.

[0044] The matching design of these two aspects is crucial to ensure the efficient operation of the system.

[0045] The specific model recommendations for the sensors and control systems involved are as follows (applicable to this technical field and solution): The control module uses industrial-grade components, such as the digital signal processor (e.g., TMS320F28335) in the frequency adjustment module 15.

[0046] The specific model of the ultrasonic generator 7 is: HK4100-1000W (frequency range adjustable from 20-60kHz, with RS485 communication interface and automatic frequency tracking function).

[0047] The specific model of the ultrasonic transducer 8 is: piezoelectric ceramic transducer, commonly used models such as PT-40 (frequency 40kHz, suitable for medium and low frequency mixing) or customized frequency band (20–60kHz) transducer components.

[0048] The control circuit board 18 integrates a microprocessor: STM32F407 series (ARM Cortex-M4 core, with rich peripheral interfaces, suitable for implementing multi-channel signal control and data processing).

[0049] Electric lifting rod 10: Linear stepper motor driver with lead screw slide module, such as J1GH-4010A (adjustable stroke, precise positioning).

[0050] Operation panel 17: Integrated touch LCD display (HMI), commonly used models such as Siemens KTP400 Basic (supports parameter setting and status display).

[0051] Power module 16: Switching power supply (input AC 220V, output DC 24V / 12V / 5V multiple channels, to power the control system and actuators).

[0052] The power amplifier in the frequency adjustment module 15 is a Class D audio power amplifier chip, such as the IRS2092 (suitable for high-frequency signal amplification and driving transducers).

[0053] All of the above models are mature and reliable components in the industrial or medical device control field, which can meet the requirements of this equipment for precision, stability and safety. The whole system has passed CE certification and meets the safety standards for medical devices. It is suitable for dental material mixing needs in dental clinics, denture processing centers and other scenarios.

[0054] Through the above steps, when using this type of universal dental material mixing machine, the operator opens the door 2, places the container holding the dental material into the lifting cylinder 4 inside the mixing chamber 3, and then starts the lifting mechanism to raise the container so that the corresponding mixing head 6 is completely immersed in the material. After closing the lifting mechanism and maintaining the position of the lifting cylinder 4, the door 2 is closed. The ultrasonic mixing mechanism is activated through the control module to transmit vibration energy to the inside of the material through the mixing head 6 to achieve molecular-level uniform mixing, which is more efficient than traditional mechanical stirring. This device achieves high uniformity mixing with no bubbles and low noise by using ultrasonic vibration mixing, and is especially suitable for high-precision dental materials that are sensitive to bubbles.

[0055] Example 2 Please see Figure 7 The difference from Embodiment 1 is that in this embodiment, the mixing head 6 is provided with multiple structural forms: the bottom surface of the mixing head 6 is a flat design, the outer peripheral surface of the mixing head 6 is a threaded design, and the bottom surface of the mixing head 6 is a threaded design.

[0056] The mixing head 6 is designed with three structural forms to adapt to different dental materials: the bottom flat design is suitable for low viscosity resin-based composite materials (such as flowable resins), which achieve rapid and uniform diffusion through planar vibration; the outer peripheral thread design is suitable for medium viscosity glass ionomer cement, which enhances the turbulence effect and improves mixing efficiency; and the bottom thread design is suitable for high viscosity silicone rubber, which increases local shear force and promotes the dispersion of viscous materials.

[0057] With a wide frequency adjustable design of 20kHz–60kHz and multiple interchangeable mixing heads, the equipment can adapt to the mixing needs of various dental materials, from low-viscosity temporary adhesives to high-viscosity silicone rubber impression materials and resin-based filling materials, making it highly versatile.

[0058] Ultrasonic mixing technology improves efficiency by more than 40% compared to traditional mechanical mixing. It achieves "multi-purpose" through a wide frequency adjustable design of 20kHz~60kHz: the low frequency band (20-30kHz) is suitable for high viscosity materials (such as silicone rubber), and the high frequency band (40-60kHz) is suitable for low viscosity materials (such as molding materials), effectively reducing bubble generation (bubble rate reduced to below 0.5%) and noise pollution (operating noise ≤65dB).

[0059] Example 3 Please see Figure 2 and Figure 4The difference from Embodiment 1 is that, in this embodiment, a heat dissipation fan is provided on the rear side of the chassis 1, and a temperature sensor 20 is provided in the inner cavity of the chassis 1.

[0060] During the mixing process, temperature sensor 20 monitors the internal temperature of the chassis 1 in real time. When the temperature exceeds the preset threshold, the cooling fan is triggered to start forced convection cooling.

[0061] The equipment adopts a closed chassis design 1, and works with temperature sensor 20 and heat dissipation fan 19 to achieve intelligent temperature control, ensuring that the working temperature is stable at 25±1℃.

[0062] Temperature sensor 20: DS18B20 (digital output, accuracy ±1°C, suitable for monitoring the internal ambient temperature of equipment).

[0063] Cooling Fan 19: DC12V axial fan, model such as MF40102 (low noise, moderate airflow, suitable for rack cooling).

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
