Technical Field
[0001] This utility model belongs to the field of automatic ultrasonic cleaning technology, and in particular relates to an automatic ultrasonic cleaning device for biodegradable green packaging equipment for express delivery. Background Technology
[0002] The automatic ultrasonic cleaning system for biodegradable express green packaging equipment is an automated ultrasonic cleaning technology and process system designed for specialized equipment used in the production, processing, and molding of biodegradable express green packaging products. It achieves efficient and non-destructive cleaning of biodegradable material residues, mold release agent residues, oil stains, dust, and other contaminants adhering to packaging equipment, and the cleaning process is an integrated cleaning method that meets green and environmental protection requirements.
[0003] Currently, existing automatic ultrasonic cleaning devices for biodegradable green packaging equipment can only achieve a cleaning effect through ultrasonic waves. However, their overall function is relatively simple, lacking features such as temperature control of the cleaning fluid, automatic replenishment of the cleaning fluid, and leakage detection. This can easily lead to unstable cleaning efficiency and frequent manual replenishment of the cleaning fluid, which not only increases the workload of operators but may also affect the cleaning quality due to insufficient cleaning fluid. Furthermore, since ultrasonic cleaning devices require continuous power during operation, if there are issues such as aging wiring or seal failure inside the equipment, leakage risks may occur, posing a threat to the personal safety of operators and the stable operation of the equipment.
[0004] To address these issues, we propose an automatic ultrasonic cleaning device for biodegradable green packaging equipment for express delivery. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the relatively simple overall function in the existing technology, and to propose an automatic ultrasonic cleaning device for biodegradable green packaging equipment for express delivery.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic ultrasonic cleaning device for biodegradable green packaging equipment for express delivery includes a fixed frame. A cleaning tank is fixedly connected to the inner wall of the fixed frame. An ultrasonic liquid level sensor and a temperature sensor are fixedly installed on the inner wall of the cleaning tank. A controller is fixedly connected to the outer wall of the fixed frame. A leakage current sensor is fixedly connected to the left side of the fixed frame, with its detection end in contact with the side wall of the cleaning tank. An automatic control switch is fixedly connected to the upper surface of one side of the fixed frame. A liquid replenishment pump is fixedly connected to the right side of the fixed frame, with its power input end connected to a liquid replenishment pipe. The cleaning tank has a hollow structure and contains an electric heating plate. An ultrasonic level sensor and a temperature sensor are fixedly installed on the rear side wall of the fixed frame. A cooling tank is connected to the fixed frame. A cooling pump is fixedly connected to the outer surface of the fixed frame. The input end of the cooling pump is fixedly connected to an inlet pipe, and the output end of the cooling pump is fixedly connected to an outlet pipe. The outer surface of the outlet pipe is fixedly connected to the inner wall of the cooling tank. A heat exchange plate is fixedly connected to the outer surface of the outlet pipe. The outer surface of the heat exchange plate is fixedly connected to the inner wall of the cooling tank. A semiconductor refrigeration chip is fixedly connected to the inner wall of the cooling tank. Four transducers are fixedly connected to the inner bottom wall of the fixed frame. The top of each transducer is fixedly connected to the bottom surface of the cleaning tank. An ultrasonic generator is fixedly connected to the upper surface of the fixed frame. Each transducer is electrically connected to the ultrasonic generator through a wire.
[0007] Preferably, four positioning blocks are fixedly connected to the outer surface of the fixed frame, and each positioning block has a positioning hole on its upper surface.
[0008] Preferably, a buzzer alarm is fixedly connected to the outer surface of the fixed frame, and the buzzer alarm is electrically connected to the controller via a wire.
[0009] Preferably, the bottom surface of the cleaning tank is fixedly connected to a drain pipe, the outer surface of the drain pipe is fixedly connected to the inner wall of the fixed frame, and the outer surface of the drain pipe is fixedly connected to a solenoid valve.
[0010] Preferably, the right end of the replenishment tube is fixedly connected to a flange, and the left side of the flange has connection holes arranged at equal intervals.
[0011] In summary, the technical effects and advantages of this utility model are as follows: 1. The cleaning tank is equipped with an electric heating plate and a temperature sensor, which, together with the controller, form a closed-loop temperature control system. The temperature sensor collects the cleaning fluid temperature data in real time and transmits it to the controller. The controller can automatically start and stop the electric heating plate according to the cleaning needs, and accurately adjust the cleaning fluid temperature to the optimal cleaning range. This greatly improves the targeting and efficiency of ultrasonic cleaning, and avoids incomplete cleaning or low efficiency caused by unsuitable temperature. At the same time, the cooling mechanism, consisting of a cooling box, a cooling pump, a heat exchange plate and a semiconductor cooling chip, can quickly cool down the cleaning fluid when the temperature is too high, ensuring comprehensive temperature control and maintaining the stability of the cleaning process. 2. By cooperating with the replenishment pump and replenishment pipe, and combined with the real-time monitoring of the cleaning fluid level by the ultrasonic level sensor, when the fluid level is lower than the set threshold, the sensor transmits a signal to the controller. The controller automatically starts the replenishment pump and completes the automatic replenishment of the cleaning fluid through the replenishment pipe. The leakage current sensor has its detection end in close contact with the cleaning tank, which can monitor the leakage current of the cleaning tank and internal circuits in real time. Once a leakage current signal is detected, it is immediately transmitted to the controller, and the controller quickly triggers the automatic control switch to cut off the power supply.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figure 1-5 An automatic ultrasonic cleaning device for biodegradable express green packaging equipment includes a fixed frame 1. A cleaning tank 2 is fixedly connected to the inner wall of the fixed frame 1. An ultrasonic liquid level sensor 4 and a temperature sensor 3 are fixedly installed on the inner wall of the cleaning tank 2. A controller 9 is fixedly connected to the outer wall of the fixed frame 1. Four positioning blocks 5 are fixedly connected to the outer surface of the fixed frame 1. Each positioning block 5 has a positioning hole 6 on its upper surface. The positioning blocks 5 and positioning holes 6 facilitate the operator to install and position the device, ensuring that the device remains stable during use and avoiding shaking or displacement of the equipment due to insecure installation, which would affect the cleaning effect.
[0016] A leakage current sensor 7 is fixedly connected to the left side of the fixed frame 1. The detection end of the leakage current sensor 7 is in contact with the side wall of the cleaning tank 2. An automatic control switch 8 is fixedly connected to the upper surface of one side of the fixed frame 1. A buzzer alarm 10 is fixedly connected to the outer surface of the fixed frame 1. The buzzer alarm 10 is electrically connected to the controller 9 through a wire. The buzzer alarm 10 is installed in the middle of the front face of the fixed frame 1, in an area that is easy for the operator to observe and hear. The buzzer alarm 10 is electrically connected to the controller 9 through a wire. The controller 9 can receive abnormal signals transmitted by the ultrasonic liquid level sensor 4, temperature sensor 3, and leakage current sensor 7. When abnormal conditions such as excessively high or low liquid level, temperature exceeding the set range, or equipment leakage are detected, the controller 9 immediately sends a trigger signal to the buzzer alarm 10, causing the buzzer alarm 10 to sound an alarm, promptly reminding the operator to troubleshoot the fault.
[0017] A liquid replenishment pump 17 is fixedly connected to the right side of the fixed frame 1. The power input end of the liquid replenishment pump 17 is fixedly connected to a liquid replenishment pipe 18. The cleaning tank 2 is a hollow structure. An electric heating plate 15 is installed inside the cleaning tank 2. Four transducers 14 are fixedly connected to the inner bottom wall of the fixed frame 1. The top of each transducer 14 is fixedly connected to the bottom surface of the cleaning tank 2. The four transducers 14 are arranged in a rectangular array on the inner bottom wall of the fixed frame 1, and the spacing between two adjacent transducers 14 is equal to ensure that the ultrasonic energy is evenly distributed in the cleaning tank 2. The transducers 14 can convert the high-frequency electrical signal generated by the ultrasonic generator 11 into mechanical vibration, which is transmitted to the cleaning liquid inside the cleaning tank 2, causing the cleaning liquid to generate high-frequency vibration and form microbubbles. The impact force generated when the bubbles burst can effectively remove the residual material, release agent residue, oil stains and dust and other pollutants attached to the surface of the biodegradable express green packaging equipment, achieving efficient cleaning. The transducers 14 are tightly installed at the bottom of the cleaning tank 2 by bolts to ensure good coupling between the transducers 14 and the cleaning tank 2.
[0018] A cooling box 16 is fixedly connected to the rear side wall of the fixed frame 1. A cooling liquid pump 21 is fixedly connected to the outer surface of the fixed frame 1. The power input end of the cooling liquid pump 21 is fixedly connected to the liquid inlet pipe 22. An ultrasonic generator 11 is fixedly connected to the upper surface of the fixed frame 1. Each transducer 14 is electrically connected to the ultrasonic generator 11 through a wire. The ultrasonic generator 11 can generate high-frequency electrical signals to provide a stable energy source for the transducers 14. The electrical signals are transmitted to the transducers 14 through the wires, so that the transducers 14 can continuously and stably convert the electrical signals into mechanical vibrations, ensuring the continuity and stability of the ultrasonic cleaning process. The ultrasonic generator 11 is equipped with a seven-inch color touch screen as the operation interface. The interface is simple and intuitive. The operator can set parameters such as cleaning time and ultrasonic power through the touch screen.
[0019] The output end of the cooling pump 21 is fixedly connected to the outlet pipe 23. The outer surface of the outlet pipe 23 is fixedly connected to the inner wall of the cooling tank 16. A heat exchange plate 24 is fixedly connected to the outer surface of the outlet pipe 23. The bottom surface of the cleaning tank 2 is fixedly connected to the drain pipe 12. The outer surface of the drain pipe 12 is fixedly connected to the inner wall of the fixed frame 1. A solenoid valve 13 is fixedly connected to the outer surface of the drain pipe 12. The drain pipe 12 and the solenoid valve 13 can realize the automatic discharge of cleaning liquid. When cleaning is completed, the solenoid valve 13 is opened to allow the waste liquid in the cleaning tank 2 to be discharged through the drain pipe 12 without manual dumping, reducing the workload of operators and avoiding waste liquid leakage. At the same time, the bottom of the cleaning tank 2 is designed with a partially inclined structure to facilitate the discharge of cleaning liquid.
[0020] The outer surface of the heat exchange plate 24 is fixedly connected to the inner wall of the cooling box 16. A semiconductor cooling chip 25 is fixedly connected to the inner wall of the cooling box 16. A flange 19 is fixedly connected to the right end of the replenishment pipe 18. The left side of the flange 19 has equidistantly arranged connection holes 20. The flange 19 and the connection holes 20 enable the replenishment pipe 18 to achieve a quick and sealed connection with the external cleaning fluid supply pipeline, effectively preventing leakage of the cleaning fluid during transmission and ensuring the stability and reliability of the replenishment process.
[0021] The working principle of this utility model is as follows: When in use, the operator first connects the temperature sensor 3, ultrasonic level sensor 4, leakage current sensor 7, controller 9, ultrasonic generator 11, solenoid valve 13, transducer 14, electric heating plate 15, liquid replenishment pump 17, cooling liquid pump 21, and semiconductor refrigeration chip 25 to one end of the automatic control switch 8, and connects the other end of the automatic control switch 8 to an external power source for power supply. At the same time, the temperature sensor 3, ultrasonic level sensor 4, leakage current sensor 7, buzzer alarm 10, electric heating plate 15, liquid replenishment pump 17, cooling liquid pump 21, semiconductor refrigeration chip 25, and automatic control switch 8 to the controller 9 to facilitate signal transmission and control. During use, the operator turns on the temperature sensor 3, leakage current sensor 7, ultrasonic liquid level sensor 4, and controller 9. The temperature sensor 3 monitors the temperature of the cleaning fluid in the cleaning tank 2 in real time and transmits the data to the controller 9. When the temperature is lower than the preset optimal cleaning temperature range, the controller 9 automatically starts the electric heating plate 15 to heat the cleaning fluid. When the temperature reaches the set upper limit, the controller 9 triggers the cooling pump 21 to operate. The cooling pump 21 draws the coolant from the cooling tank 16 through the inlet pipe 22. The coolant flows through the outlet pipe 23 and then through the heat exchange plate 24. The semiconductor cooling chip 25 continuously cools the coolant in the cooling tank 16. The heat exchange plate 24 contacts the outer wall of the cleaning tank 2 and quickly reduces the temperature of the cleaning fluid through heat exchange, forming a precise temperature closed-loop control. The ultrasonic liquid level sensor 4 continuously collects the cleaning fluid level data. If the liquid level is lower than the set threshold, the controller 9 immediately starts the replenishment pump 17. The external cleaning fluid is automatically replenished into the cleaning tank 2 through the replenishment pipe 18 and the flange 19, which is sealed to the external supply pipeline. The replenishment stops when the liquid level reaches the standard value. The detection end of the leakage current sensor 7 is closely attached to the left side of the cleaning tank 2 to monitor the leakage current of the equipment circuit and the cleaning tank 2 in real time. Once a leakage current signal is detected, the controller 9 quickly sends a command to the automatic control switch 8 to cut off the power supply. At the same time, the buzzer alarm 10 is triggered to emit a sharp alarm sound to remind the operator to troubleshoot the fault in time. The buzzer alarm 10 can be equipped with a built-in battery to help the staff avoid power failure after the automatic control switch 8 is turned off. During cleaning, the operator sets the cleaning time and ultrasonic power parameters through the color touch screen of the ultrasonic generator 11. The ultrasonic generator 11 transmits high-frequency electrical signals to four transducers 14 arranged in a rectangular array. The transducers 14 convert the electrical signals into mechanical vibrations and transmit them to the cleaning tank 2, causing the internal cleaning fluid to generate high-frequency vibrations and form a large number of tiny cavitation bubbles. The local high-pressure impact force generated when the bubbles burst effectively removes residues, release agent residues, oil stains and dust adhering to the surface of the biodegradable express green packaging equipment.
