[0039] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0040] Ultrasonic and high-pressure spray combined cleaning, which offers superior cleaning results, is typically used in large-scale equipment. Areas for improvement in existing compact, miniaturized medical packaging bottle cleaning technologies include:

[0041] Low cleaning efficiency: Manual brushing or single spraying requires multiple rinses, and the cleaning time for a single item is more than 30 minutes.

[0042] Poor environmental performance: Solvent cleaning generates VOC emissions, which does not comply with the GB 16297-1996 Integrated Emission Standard for Air Pollutants.

[0043] Insufficient cleanliness: Complex structures on the bottle, such as the bottle neck threads and blind holes on the inner wall, are difficult to clean thoroughly, and residual particles affect the quality of the medicine.

[0044] High energy consumption: Distillation recovery of solvent requires long-term high-temperature heating at 120-150℃, accounting for more than 40% of energy consumption.

[0045] The principle of this utility model is as follows:

[0046] 1) Ultrasonic cleaning: Utilizes high-frequency sound waves (20-40kHz) to create cavitation in liquids, forming microbubbles. When these microbubbles burst, they generate impact forces exceeding 1000 atmospheres, effectively removing stubborn dirt. Typical equipment includes ultrasonic bottle washers with a power density ≥0.3W / cm³. 2 It supports temperature adjustment from 40-60℃ and is suitable for rough washing of 1-20ml ampoules and 2-100ml vials.

[0047] 2) High-pressure spray cleaning: A 0.8-1.2 MPa high-pressure pump atomizes the cleaning solution through fan-shaped or rotating nozzles, forming micron-sized droplets with a diameter of 10-100 μm, covering the bottle surface and inner pores. For example, the high-pressure atomization system used in the bulk cargo yard of Qingdao Port generates 200 L of atomized water per minute, forming a 30-meter-wide dust suppression belt, controlling the PM10 concentration at 80 μg / m³. 3 the following.

[0048] 3) Composite type: Combining the advantages of ultrasonic waves and high-pressure spraying, ultrasonic waves are used to remove microscopic dirt, and then high-pressure spraying is used to rinse away macroscopic residues, achieving three-dimensional cleaning "from the inside out".

[0049] This utility model includes: a bottle inlet / outlet system, a cleaning system, and a control system. The bottle inlet / outlet system, cleaning system, and control system are installed on the chamber of a medical high-pressure spray ultrasonic composite optimized energy-saving bottle washing equipment. The bottle inlet / outlet system includes a drive unit, a bottle inlet channel, a mechanical gripper, a rotating ring frame, a conveyor belt, and a bottle outlet channel; the cleaning system includes an ultrasonic generator, an ultrasonic water tank, a cleaning tank, and high-pressure nozzles; the control system includes a control box, an automatic sensing device, a touch screen, and sensors.

[0050] In this utility model, the bottle inlet / outlet system, the cleaning system, and the control system, as well as the drive device, bottle inlet channel, mechanical gripper, rotating ring frame, conveyor belt, and bottle outlet channel of the bottle inlet / outlet system; the ultrasonic generator, ultrasonic water tank, cleaning tank, and high-pressure nozzle of the cleaning system; and the control box, automatic sensing device, touch screen, and sensors of the control system, all adopt existing mature products.

[0051] The purpose of this utility model is to rationally and effectively reconstruct the aforementioned existing technologies and products through a new combination of functions and structural layout of the hospital, so as to achieve the effect of compact integration and convenient installation.

[0052] Bottle loading and unloading systems are core automated equipment in production lines for bottled products such as beverages and pharmaceuticals. They are primarily responsible for automating processes such as bottle conveying, positioning, filling, and sealing. These systems are widely used in production lines in the food and beverage, and pharmaceutical packaging industries.

[0053] Cleaning systems are automated devices used in modern industrial production to remove contaminants from the surfaces of equipment, containers, or products. They are widely used in industries such as food and beverage, pharmaceuticals, and electronics semiconductors.

[0054] A control system is a management system with its own goals and functions, consisting of a control subject, a control object, and a control medium. It achieves its control objectives by using computers to participate in control and by communicating with the controlled object through auxiliary components.

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0056] Example 1: As shown in the attached document Figure 1 As shown, the container 1 is equipped with a bottle inlet / outlet system, a cleaning system, and a control system. The bottle inlet / outlet system is sequentially connected to a bottle inlet channel 18 driven by a drive unit 20, a mechanical gripper 7, a conveyor belt 22, a rotating ring frame 3, and a bottle outlet channel 19. An ultrasonic water tank 2 and a cleaning tank 13 of the cleaning system are installed under the conveyor belt 22 and the rotating ring frame 3. An ultrasonic generator 6 of the cleaning system is installed under the ultrasonic water tank 2 and connected to the ultrasonic water tank 2. The rotating ring frame 3 of the cleaning system is installed on the cleaning tank 13. A spray frame 4 is installed in the middle of the rotating ring frame 3. A high-pressure nozzle 5 is installed on the spray frame 4. A control box 8 of the control system is installed on the outer wall of the container 1. A touch screen 9 is installed on the control box 8. Automatic sensing devices 12 and sensors 15 of the control system are installed at multiple points on the bottle inlet / outlet system and the cleaning system components.

[0057] As attached Figure 2 , 3 As shown in Figures 4, 5, and 6, a bottle inlet channel 18 is provided on the rear side of the left end face of the chamber 1, and a bottle outlet channel 19 is provided on the right side of the front end face of the chamber 1; the bottle inlet channel 18 and the bottle outlet channel 19 are seamlessly connected to the conveyor belt 22 installed inside the chamber 1.

[0058] As mentioned above, the installation path of the conveyor belt 22 is as follows: the front end of the conveyor belt 22 is connected to the inner end of the inlet channel 18 and then extends into the ultrasonic water tank 2. It then extends from the ultrasonic water tank 2 into the rotating ring frame 3 and rotates counterclockwise. Finally, it is led out from the rotating ring frame 3 and output from the chamber 1 through the bottle outlet channel 19.

[0059] As mentioned above, an automatic sensing device 12 is provided at the bottle inlet channel 18 or the bottle inlet end of the conveyor belt 22, which can accurately identify the arrival of the washing bottle 23 and control the moving speed of the conveyor belt 22 to ensure that the washing bottle 23 enters the chamber 1 smoothly; another automatic sensing device 12 is also equipped at the bottle outlet channel 19 or the bottle outlet end of the conveyor belt 22 to detect and ensure that the bottle is smoothly output after washing in the washing bottle 23 and avoids congestion.

[0060] As described above, a liftable spray frame 4 is installed on the right side of the top surface of the chamber 1. The spray frame 4 is installed in the middle of the rotating ring frame 3. Multiple sets of high-pressure nozzles 5 at different angles are installed on the spray frame 4. These high-pressure nozzles 5 can automatically adjust the spray pressure and angle according to the type of bottle 23 being washed and the degree of dirt, so as to achieve all-round, no-dead-angle high-pressure spray cleaning. The spray frame 4 can be raised after the cleaning operation is completed for easy maintenance and repair.

[0061] As described above, an ultrasonic generator 6 is installed inside the chamber 1. In particular, a control box 8 is vertically installed on the front left side of the chamber 1, and the ultrasonic generator 6 is installed at the bottom of the control box 8. The ultrasonic generator 6 is connected to the ultrasonic water tank 2. That is, the ultrasonic waves generated by the ultrasonic generator 6 are evenly transmitted to the cleaning fluid in the ultrasonic water tank 2 through a conduction device installed inside the chamber 1. Utilizing the cavitation effect of the ultrasonic waves, stubborn dirt inside the washing bottle 23 in the ultrasonic water tank 2 is further removed. At the same time, the chamber 1 is also equipped with a bottom-sloping drainage trough 10 and a drain outlet 11. After the washing bottle 23 is cleaned, the chamber 1 can quickly discharge the cleaning fluid and residual impurities through the drainage trough 10 and the drain outlet 11. The drain outlet 11 is further connected to a drainage pipe. The drainage trough 10 and the cleaning tank 13 are connected through a filter device 14. The filter device 14 is installed on the drainage trough 10, the cleaning tank 13, or the drainage pipe to prevent impurities from clogging the external public drainage system.

[0062] As mentioned above, various sensors and control components related to the control system are arranged inside the chamber 1. The control system specifically includes: a control box 8, a touch screen 9, an automatic sensing device 12, and sensors 15. Sensors 15 include temperature sensors, pressure sensors, and liquid level sensors. Each type of sensor 15 is installed on different parts of the chamber 1, including: an ultrasonic water tank 2, a rotating ring frame 3, a spray frame 4, a high-pressure nozzle 5, an ultrasonic generator 6, a mechanical gripper 7, a drainage trough 10, a drainage outlet 11, a cleaning tank 13, a filter device 14, a drying fan 17, a bottle inlet channel 18, a bottle outlet channel 19, a drive device 20, and a conveyor belt 22. The temperature sensor monitors the cleaning fluid temperature in real time to ensure the cleaning process is carried out within a suitable temperature range; the pressure sensor monitors the spray pressure to ensure the high-pressure nozzle 5 operates stably; and the liquid level sensor 15 controls the amount of cleaning fluid added to the ultrasonic water tank 2, drainage trough 10, and cleaning tank 13 to prevent excessive or insufficient cleaning fluid from affecting the cleaning effect. These sensors 15 transmit data to the various components of the control system in real time, achieving precise control of the entire cleaning process. The main structure of the cabin 1 is designed with full consideration of the installation and layout of each component. All systems work closely together and coordinate effectively, while facilitating daily operation and maintenance, which greatly improves the working efficiency and cleaning quality of the bottle washing machine.

[0063] In particular, the cleaning tank 13 is installed on the underside of the conveyor belt 22 between the bottle inlet channel 18 and the ultrasonic water tank 2. After the washing bottle 23 enters the chamber 1 through the bottle inlet channel 18, it is picked up by the mechanical gripper 7 and placed on the conveyor belt 22. The conveyor belt 22 then carries it through the cleaning tank 13 for soaking and washing, and then it enters the ultrasonic water tank 2 for ultrasonic cavitation cleaning.

[0064] As mentioned above, the ultrasonic generator 6 produces high-frequency sound waves, typically between 20,000 Hz and 100,000 Hz, which falls within the range of ultrasound inaudible to the human ear. The high-frequency oscillation signal is converted into high-frequency mechanical oscillations by a transducer and propagates into the cleaning solvent. The ultrasonic waves radiate forward in the cleaning liquid in alternating compression and sparsity phases. The sound wave vibrations cause the formation of tiny bubbles (called cavitation bubbles) in the liquid. These bubbles are compressed in the high-pressure phase of the sound waves and expand in the low-pressure phase. When the bubbles expand to a certain extent, they rapidly burst, releasing energy and generating instantaneous high pressure exceeding 1000 atmospheres, continuously impacting the surface of the object and causing dirt to peel off quickly. In medical packaging bottle cleaning systems, the ultrasonic generator typically operates at a frequency of 40 kHz, effectively removing residual drugs, microorganisms, and other impurities from the bottle, ensuring that the cleaned bottle meets strict hygiene standards. The ultrasonic power 6 is typically configured as 2 kW, with a frequency selection of 27 kHz ± 1.5 kHz.

[0065] The aforementioned high-pressure nozzle 5 has an operating pressure range of over 20 bar, a spray angle of 360° omnidirectional coverage, and a flow rate range of 2.5-6 m³ / h.3 / h, Material: 316L stainless steel, Main nozzle: Fixed angle spray, covering four quadrants of the bottle body, Rotating nozzle: Adjustable angle design (15°-90°), specifically targeting the bottom and neck of the bottle, Coordinating working pressure: Main nozzle 20-25 bar, Rotating nozzle 15-20 bar anti-splash. The multi-angle adjustable high-pressure nozzle 5 uses a worm gear drive to manually rotate the adjustment ring to achieve stepless positioning from 15° to 90°, or uses a servo motor drive and shape memory alloy actuator.

[0066] As mentioned above, the rotating ring frame 3, also known as the annular bottle conveyor, is the core conveying component of the medical packaging bottle cleaning system. It employs a closed-loop design to achieve continuous cyclic conveying of the bottles. A servo control system ensures accurate positioning of the bottles at each cleaning station, with a positioning accuracy of ±0.1mm, guaranteeing consistency in the cleaning process. Different clamps can be configured to adapt to the conveying needs of various bottle sizes, such as vials and ampoules. Standardized modular assembly facilitates quick replacement of clamps of different sizes. Bottle type conversion can be completed within 30 minutes, adapting to various bottle sizes from 5-50ml. A servo motor drives a chain to circulate along the guide rail via a reduction mechanism. The clamps hold the bottles as they sequentially pass through each cleaning station. The PLC control system coordinates the timing of actions at each station to complete the cleaning process.

[0067] As mentioned above, the spray frame 4, also known as the rotating spray arm, is a core component of the medical packaging bottle cleaning system, mainly used to achieve 360° cleaning of the inner and outer surfaces of the bottle without dead angles. In the pharmaceutical and medical fields, the cleanliness of packaging bottles is directly related to drug safety. The rotating ring frame 3, through its special design, ensures that the cleaning process meets the hygiene standards required for GMP certification. For example, CN213469004U describes a rotating spray arm device that separates cleaning water from rinsing water. This rotating spray arm device that separates cleaning water from rinsing water includes a rotating shaft mounted on the main body of the cleaning chamber and a rotating bushing coaxially mounted with the rotating shaft. A water inlet pipe assembly is installed inside the rotating bushing, including a rinsing water inlet pipe and a cleaning water inlet pipe that are respectively fixedly connected to the main body of the cleaning chamber. The same end of the rinsing water inlet pipe and the cleaning water inlet pipe are respectively inserted into the rotating bushing and coaxially mounted with the rotating bushing. The rinsing water inlet pipe is connected to the rinsing spray arm, and the cleaning water inlet pipe is connected to the cleaning spray arm. The rotating bushing is also equipped with a sealing device.

[0068] As mentioned above, the automatic sensing device 12 is a key safety and efficiency component in the medical packaging bottle cleaning system. It has safety protection, intelligent identification and process control functions, and performs tasks such as fully automatic induction switch / automatic induction suction / automatic identification of water inlet and drainage / fault self-diagnosis / detection of blockage and abnormal wear alarm shutdown. It uses relays or servo motors as drive and execution components.

[0069] As mentioned above, sensor 15 includes a bottle type detection sensor, a position sensor, a liquid level sensor, a temperature sensor, a humidity sensor, a photoelectric sensor, and a conductivity sensor, etc. Among them:

[0070] Bottle shape detection sensor: Used to identify packaging bottles of different sizes and materials. It detects bottle size, shape, and other characteristics through optical or mechanical means. This provides the system with a basis for personalized cleaning solutions. It identifies bottle shape characteristics by emitting infrared light or a laser beam, receiving reflected signals from the bottle, and analyzing changes in reflection time or intensity.

[0071] Position sensors monitor the position and movement of bottles on the conveyor belt, ensuring accurate positioning of bottles at each cleaning station. Types include proximity switches and photoelectric sensors. When a bottle enters the detection area, the sensor's electromagnetic or capacitive field changes, triggering a switch signal.

[0072] Liquid level sensor: Monitors the liquid level in the cleaning tank in real time. Prevents the equipment from running dry due to low water level. Ensures the cleaning fluid volume meets process requirements. Float-type sensors trigger microswitches by the rise and fall of a float with the liquid level; electrode-type sensors utilize the conductivity of the liquid to form a circuit; ultrasonic-type sensors measure distance by transmitting and receiving sound waves.

[0073] Conductivity sensor: Detects the conductivity of rinse water. Ensures no chemical residue, and traceable data provides a basis for cleaning quality assessment. Typical application cases show that cleanliness can be improved by 75%.

[0074] Temperature sensor: Monitors the temperature of the cleaning solution and drying air. Ensures the temperature is maintained within the set range (e.g., 95°C hot water dissolves stubborn grease). Prevents abnormal temperatures from affecting cleaning results or damaging the equipment.

[0075] In addition, the drive unit 20 uses a servo motor drive, and the servo control system achieves high-precision positioning and speed control. In the SPI-DOSITECNO bottle washing machine, only two moving parts need to be controlled: the central shaft and the discharge device. Compared to traditional machines, this reduces hundreds of moving parts, greatly lowering the risk of secondary contamination. The servo driver receives PLC commands and controls the motor to move along a preset trajectory, while the encoder provides real-time position feedback, forming a closed-loop control. Alternatively, a variable frequency motor drive can be used. The frequency converter adjusts the power supply frequency and voltage to control the motor speed. In a 10ml vial ultrasonic cleaner, this is used to control the turntable and dial, with adjustable speed to meet different cleaning needs. The frequency converter changes the power supply frequency and voltage to adjust the motor speed, achieving speed control of components such as the conveyor belt and turntable. Alternatively, a pneumatic drive system can be used, utilizing compressed air to control the extension and retraction of the telescopic rod. A typical application is a pneumatic telescopic bottle cleaning system, which can achieve coordinated cleaning of dynamic extension and high-pressure impact. A solenoid valve controls compressed air to enter the cylinder, pushing the piston rod to move linearly, achieving the extension and retraction positioning of components such as the nozzle. Servo motors are suitable for applications requiring high-precision positioning, such as robotic grippers; frequency converters are suitable for components requiring speed adjustment, such as conveyor belts; and pneumatic systems are suitable for simple actions such as spray head extension and retraction. The frequency converter drive unit 20 drives the conveyor belt 22 at an adjustable speed of 60-1200 bottles / minute, ensuring bottles enter the cleaning tank smoothly with a breakage rate of <0.1%. The servo motor drive unit 20 controls the raising and lowering of the transducer of the ultrasonic generator 6, precisely adjusting the distance between it and the liquid surface in the ultrasonic water tank 2, maintaining the liquid level 100mm above the vibration surface for optimal cavitation. The frequency converter drive unit 20 drives the rotating ring frame 3 to rotate via a reducer, with the speed matching the ultrasonic frequency to ensure uniform cleaning. The servo motor drive unit 20 controls the rotating ring frame 3 to rotate the spray arm 360°, with a positioning accuracy of ±0.1°, ensuring full coverage cleaning. The pneumatic system drive unit 20 controls the extension and retraction of the high-pressure nozzle 5, with a stroke of 50-200mm, for targeted cleaning of the bottle bottom and neck bottlenecks. The drying fan 17 is driven by a high-power variable frequency motor, and a servo motor is used to control the opening of the damper of the drying fan 17 to accurately distribute the air volume in each area and ensure the uniformity of drying.

[0076] In this embodiment of the utility model, the bottle inlet channel 18 and the bottle outlet channel 19 are respectively located on the left and right sides of the control box 8 and the touch screen 9, and the ultrasonic water tank 2 is arranged in front of the control box 8 and the touch screen 9; the rotating ring frame 3, the spray frame 4, and the high-pressure nozzle 5 are arranged in front of the control box 8 and the touch screen 9, which maximizes the arrangement of the cleaning path within the limited equipment installation space, which is sufficient to accommodate soaking bath washing, ultrasonic cavitation and high-pressure spraying, as well as controlled drainage and drying, and is also convenient for operation and control.

[0077] In this embodiment of the invention, a bottle type detection sensor is installed on the bottle inlet channel 18, i.e., the loading station at the front end of the conveyor belt 22, to identify the bottle type and retrieve the corresponding cleaning program. Simultaneously, it coordinates with the mechanical gripper 7 installed at this loading station to accurately grasp the bottles 23 being washed and entering the chamber 1. Liquid level sensors are installed in the ultrasonic water tank 2, the cleaning tank 13, and the drainage tank 10 to maintain an appropriate cleaning liquid volume, and temperature sensors monitor the cleaning liquid temperature, typically 40-60℃. At the high-pressure spray station, i.e., on the rotating ring 3, a position sensor triggers the spray sequence, and a flow sensor monitors the spray pressure (20-25 bar). Furthermore, at the drying station, i.e., on the drying fan 17 at the inner end of the bottle outlet channel 19, a temperature sensor controls the hot air temperature to 40-100℃. A humidity sensor determines the degree of drying. At the unloading station, i.e., at the outer end of the bottle outlet channel 19, a photoelectric sensor counts the number of bottles that have been cleaned, and a position sensor coordinates the unloading action of the robotic arm.

[0078] In this embodiment of the invention, the high-pressure nozzle 5 is connected to a high-pressure water supply device via a pipe. The ultrasonic generator 6 is connected to the power supply and control host in the control box 8 via a cable. The conveyor belt 22 is driven by the drive device 20 and connected to the control host in the control box 8. The mechanical gripper 7 is installed along the conveyor belt 22 inside the cabin 1 and communicates with the control host in the control box 8.

[0080] In this embodiment of the utility model:

[0081] 1) Cleaning system;

The sprayer angles cover horizontal, inclined, and vertical directions, ensuring no cleaning dead spots. It has an automatic spray pressure adjustment function, which can be flexibly adjusted according to the bottle type and the degree of dirt. Bottle types include glass bottles, plastic bottles, and different bottle curvatures and mouth diameters. Dirt conditions include dirt thickness and viscosity. For example, for narrow-mouthed, deep bottles, the sprayer can increase pressure and adjust the angle to reach deeper into the cleaning process; for areas with thick dirt, the sprayer automatically increases the water flow impact force.

[0083] ② Ultrasonic generator: Installed inside chamber 1, adjacent to ultrasonic water tank 2 and cleaning tank 13. It generates ultrasonic waves through high-frequency oscillation, uniformly transmitting ultrasonic energy into the cleaning fluid. As the ultrasonic waves propagate in the cleaning fluid, they create a cavitation effect, causing countless tiny bubbles to form and burst on the bottle wall and the surface of the dirt. This impact force then peels away stubborn dirt, achieving deep cleaning.

[0084] 2) Bottle inlet / outlet system;

[0085] ① Conveyor Belt 22: Made of high-strength, chemically resistant material, it runs through the entire process of loading, cleaning, draining, and unloading. The surface of conveyor belt 22 is equipped with positioning grooves or anti-slip textures to prevent the bottles 23 from sliding or shifting during transport, ensuring positional accuracy. The conveying speed of conveyor belt 22 can be adjusted within a certain range according to actual needs to meet different cleaning rhythm requirements.

[0086] ②Mechanical Gripper 7: Composed of a robotic arm, gripper, and drive unit. The robotic arm has multiple joints, allowing for flexible extension and rotation for precise positioning. The gripper features a special design with different gripping methods depending on the bottle's shape and size, such as a wraparound grip for round bottles and a clamping grip for square bottles, ensuring a firm grip without damaging the bottle. The drive unit, based on instructions from the intelligent control system, controls the movements of the robotic arm and gripper to complete automatic bottle loading, transfer between different cleaning stations, and unloading operations.

[0087] 3) Control system;

[0088] ① Touchscreen 9 and its operating interface: Installed in a prominent position on the top of the control box 8, serving as the operation panel, with a simple and intuitive interface design.

[0089] ② Control host installed in control box 8: As the core of the control system, it is located in a dedicated control box 8 inside the equipment. The control host receives parameter commands input from the touch screen 9 and sends control signals to components such as the high-pressure nozzle 5, ultrasonic generator 6, conveyor belt 22, and mechanical gripper 7 through wiring connections, coordinating the collaborative work of each component. At the same time, it collects feedback data from various sensors 15 in real time, monitors the cleaning process, judges the operating status of the equipment, and ensures the stable and efficient operation of the entire cleaning process.

[0090] In this embodiment, pressure regulating valves and flow controllers are installed on the water supply and drainage pipes connected to the high-pressure nozzle 5, ultrasonic water tank 2, drainage trough 10, drainage outlet 11, and cleaning tank 13 to ensure a stable and compliant high-pressure water flow. The ultrasonic generator 6 is connected to a power supply and control unit via a cable. The power supply provides electrical energy, and the control unit adjusts the operating frequency and power of the ultrasonic generator 6.

[0091] The conveyor belt 22 is installed on a track inside or on the side of the cabin 1, and is driven by a drive unit 20. The drive unit 20 is connected to the control host and receives control signals to adjust the speed of the conveyor belt 22. The mechanical gripper 7 consists of a robotic arm, a gripper, and a drive unit. The mechanical gripper 7 is installed on the cabin 1, communicates with the control host, and acts according to instructions. Alternatively, the mechanical gripper 7 is installed on a movable bracket, which cooperates with a guide rail fixed to the cabin 1 to achieve horizontal and vertical movement. The guide rail is controlled by the drive unit 20, which communicates with the control host and acts according to instructions.

[0092] Furthermore, the touchscreen 9 of the control system is connected to the control host via a data cable to achieve data interaction. The control host is connected to other components via cables and control lines to build a complete control network, realizing intelligent control of the entire equipment.

[0093] In this embodiment, preferably, the chamber 1 serves as the main structure of the bottle washing machine and is an integrated design. The internal space of the chamber 1 houses the drainage trough 10, the washing trough 13, the bottles to be washed, and the washing liquid flow channel. The outer wall of the chamber 1 is made of high-strength, corrosion-resistant 316L stainless steel. This material can effectively resist the corrosion of various washing liquids and the wear and tear caused by frequent washing operations, ensuring the long-term stable operation of the equipment. The outer wall of the chamber 1 adopts a multi-layer composite structure. The inner layer directly contacts the bottles and washing liquid, with a smooth surface and no dead corners, facilitating the rinsing and removal of dirt. The middle layer is a reinforcing structural layer, enhancing the overall strength of the body so that it can withstand the impact of high-pressure spraying and ultrasonic cleaning. The outer layer serves as protection and heat insulation, reducing heat loss and protecting the internal structure from external collisions and environmental erosion.

[0094] In this embodiment of the present invention, preferably, the body 1 is 2065mm long, 1706mm wide, and 850mm high; the disc-shaped conveyor belt 3 has a radius of 705mm; the ultrasonic water tank 2 is 1258mm long; the drainage trough 10 is 842mm long; the cleaning trough 13 is 673mm long; and the support leg 21 is 30mm high.

[0095] In this embodiment of the utility model, the control box 8 and touch screen 9 of the control system are supported by integrated control via PLC+HMI:

[0096] Parameter visualization: The touchscreen displays real-time data such as cleaning temperature, pressure, and frequency, and supports multilingual switching.

[0097] Fault warning: Built-in sensors monitor the concentration of cleaning fluid and the condition of nozzle blockage. When an abnormality occurs, an alarm will be triggered and the machine will be shut down automatically.

[0098] Furthermore, the control system also supports data traceability:

[0099] Batch Management: Stores cleaning records for each batch (bottle type, time, solvent consumption), supports USB export or cloud upload, and complies with IATF 16949 quality management system requirements.

[0100] Energy consumption analysis: Statistical analysis of energy consumption per unit (kW·h / unit) to optimize process parameters and reduce operating costs.

[0101] Preferably, the conveyor belt 22 and the rotating ring frame 3 are integrated into a bottle-carrying transmission conveyor. Preferably, the spray frame 4 and the rotating ring frame 3 are integrated into a single installation.

[0102] In this embodiment of the present invention, preferably, the automated bottle loading and unloading system includes a conveyor belt 22 and a mechanical gripper 7, which realizes automatic loading, cleaning and unloading of bottles in the washing 23.

[0103] After the equipment is started, the operator sets the cleaning parameters on the touch screen 9, such as a cleaning time of 15 minutes, a spray pressure of 3 MPa, and an ultrasonic power of 400 W. The control host receives the command and drives the mechanical gripper 7 to pick up the washing bottle 23 from the cleaning area and place it on the conveyor belt 22. The conveyor belt 22 will uniformly transport the washing bottle 23 to the cleaning area of ​​the cleaning tank 13, and perform a preliminary rinse on the bottle body to remove most of the surface dirt. At the same time, the ultrasonic generator 6 is activated, generating a cavitation effect in the cleaning solution in the ultrasonic water tank 2 to further remove stubborn dirt inside the bottle. Then, the washing bottle 23 continues to move forward with the conveyor belt 22, or is transferred by the mechanical gripper 7 to the rotating ring frame 3 and adjusted in relation to the spray frame 4. At this time, the high-pressure nozzle 5 sprays water at the preset pressure and angle to complete the final cleaning. After cleaning, the conveyor belt 22 will transport the washing bottle 23 to the drainage area above the drainage tank 10 and drainage outlet 11, where the cleaning solution will be discharged by gravity or an auxiliary drainage device. Finally, the robotic gripper picks up the cleaned bottles from the conveyor belt and places them in the unloading area. After drying by the drying fan 17, they are output through the bottle outlet channel 19, completing the entire cleaning process. During the cleaning process, the control unit monitors the operating status of each component in real time. If any abnormalities occur, such as abnormal pressure or motor failure, an alarm signal is immediately issued and the equipment operation is suspended to ensure the stability of the equipment and the cleaning effect.

[0104] Example 2:

[0105] In this embodiment of the invention, the functional cleaning module is optimized as follows:

[0106] Preferably, in the ultrasonic cavitation enhancement module; the transducer layout uses a 40kHz / 120kHz dual-frequency ultrasonic transducer with a power density of 10W / cm². 2It covers the bottle surface and internal holes with a diameter ≥2mm. Through pulse modulation technology with a duty cycle of 50%-80%, it increases cavitation intensity by 30%, removing stubborn oil and grease. Intelligent frequency scanning: It monitors the resistance of the cleaning fluid in real time, with a frequency range of 35-125kHz, and automatically adjusts to the optimal cleaning frequency, adapting to different materials such as glass, aluminum alloy, and plastic bottles.

[0107] Preferably, in the high-pressure spray optimization module, the high-pressure nozzle 5 is designed as follows: A fan-shaped nozzle with a spray angle of 60° and a flow rate of 15L / min, covering the side walls and bottom blind areas of the bottle. A rotating nozzle with a rotation speed of 300rpm, forming a spiral liquid film to enhance the scouring force. Pressure control: The spray pressure (0.8-1.2MPa) is adjusted via a variable frequency pump to match the requirements of different cleaning stages, including 1.2MPa for the coarse washing stage and 0.8MPa for the rinsing stage.

[0108] The implementation principle of this embodiment is as follows:

[0109] The equipment is started, the cleaning parameters are set, and the mechanical gripper 7 grabs the washing bottle 23 and places it on the conveyor belt 22.

[0110] Pretreatment stage: Purified water rinsing in cleaning tank 13: Surface dirt is softened and removed by 93°C high-temperature water through upper and lower double-layer spray arms, reducing the amount of subsequent cleaning agent required. Acid neutralization: A 5% trisodium phosphate solution is injected to neutralize alkaline residues, such as sodium hydroxide cleaning agent, preventing corrosion of the bottle.

[0111] Composite Cleaning Stage: The conveyor belt transports the wash bottle 23 to the composite cleaning area. The ultrasonic generator 6 starts cleaning, and the high-pressure nozzle 5 sprays water for rinsing. Ultrasonic Pre-cleaning: The wash bottle 23 is immersed in the 40-60℃ cleaning solution in the ultrasonic water tank 2. The ultrasonic generator 6 starts 40kHz ultrasound for 5 minutes to remove microscopic dirt. High-Pressure Spray Fine Cleaning: The high-pressure nozzle 5 switches to 1.2MPa high-pressure spray to directionally rinse areas such as threads and blind holes on the inner wall of the wash bottle 23 for 3 minutes.

[0112] Rinsing and Drying Stages: Three-stage rinsing: Rinsing is performed sequentially with purified water, water for injection, and deionized water to ensure detergent residue ≤1ppm. After the bottles are drained in washing bottle 23, they are dried with HEPA hot air via drying fan 17: Drying fan 17 has an independent air heater with a controllable temperature of 40-90℃, and works with a high-efficiency circulating fan to spray hot air through top and bottom spray arms, increasing drying efficiency by 50%. After cleaning, conveyor belt 22 will transport the bottles from washing bottle 23 to the bottle outlet channel 19, where the mechanical gripper 7 will grab and unload the cleaned bottles from washing bottle 23.

[0113] Trial results showed that the cleaning pass rate reached 99%, and the water and power consumption were lower than traditional bottle washers. Compared with traditional single-spray bottle washers, the cleaning time was reduced by 40%, and the cleaning effect was improved by nearly 30%. Compared with manual cleaning, it greatly reduced labor intensity and improved cleaning efficiency and quality.

[0114] In this embodiment of the utility model:

[0115] Efficiency improvement: The cleaning time for a single bottle in the washing machine is reduced to less than 10 minutes, supporting continuous production.

[0116] Energy saving and consumption reduction: solvent recovery rate >98%, unit energy consumption reduced by more than 30%.

[0117] Cleanliness meets standards: Meets ISO 16232 Class 4 standards, with particle count ≤1000 particles per bottle for particles ≥5μm in diameter.

[0118] Intelligent control: The system integrates environmental monitoring of temperature, humidity, and dust concentration with functions such as fault self-diagnosis and remote operation and maintenance.

[0119] In this embodiment of the utility model:

[0120] Preferably, the water temperature is controlled to a maximum of 93°C; the cleaning agent is automatically dispensed; and the wastewater is filtered in four stages: surface → rough → relatively fine → fine.

[0121] Preferably, the composite bottle washing process is controlled by the PLC system of the control box 8, supporting a production cycle of 40-60 bottles / minute, and is equipped with a residual water removal device and a water for injection cleaning system to achieve seamless connection from coarse washing to sterilization oven.

[0122] To verify the effectiveness of the implementation, a trial was conducted in the production workshop of a large pharmaceutical company. 1000 identical medicine bottles were selected and divided into two groups of 500 each. One group was cleaned using the medical-grade bottle washer developed in this invention, while the other group was cleaned using a traditional bottle washer.

[0123] The cleaning parameters for this bottle washer are set as follows: cleaning time 12 minutes, spray pressure 4MPa, and ultrasonic power 350W. After cleaning, professional testing equipment is used to test the medicine bottles for microbial and dirt residue. The results show that the microbial residue level on the medicine bottles is lower than the industry standard limit, and the dirt residue is almost invisible, achieving a cleaning pass rate of 99%. Furthermore, the cleaning process consumes 500 liters of water and 10 kWh of electricity.

[0124] Traditional bottle washers, following their standard cleaning procedures, often result in excessive levels of microorganisms and noticeable dirt residue on medicine bottles after cleaning, with a cleaning pass rate of only 70%. They consume 800 liters of water and 15 kilowatt-hours of electricity. In comparison, this bottle washer demonstrates significant advantages in cleaning effectiveness, water conservation, and energy efficiency.

[0125] For comparison with the embodiments of this utility model, the following comparative examples are provided:

[0126] Compared to traditional single-spray bottle washers, which have fixed nozzles and cannot adjust pressure or angle, resulting in incomplete cleaning of some bottle areas, this bottle washer reduces cleaning time by 40% and improves cleaning effectiveness by nearly 30% for the same number of medicine bottles. Compared to manual cleaning, which is extremely inefficient (each person can only clean 50-80 bottles per hour, and cleaning results are greatly affected by the operator's skill level and work condition, making consistency difficult to guarantee), this bottle washer can clean 200-300 bottles per hour with stable and reliable cleaning results, significantly reducing labor intensity and improving cleaning efficiency and quality.

[0127] Based on the embodiments of this utility model described above, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this utility model.
