Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an ultrasonic cleaning device with automatic material discharge. Background Technology

[0002] The hospital's intravenous medication preparation center (IVF center) is located in an environment designed according to international standards and drug characteristics, where professional staff prepare intravenous medications according to standard procedures. The preparation follows the principle of "one basket per prescription," with each prescription's medication stored in a separate basket, resulting in a high usage of these baskets. Due to the special nature of the medicines and the possibility of spills or leaks during handling, medicine baskets are easily contaminated. To ensure the hygiene of the medicines and the cleanliness of the preparation environment, medicine baskets must be thoroughly cleaned promptly after use. Currently, the cleaning of medicine baskets is mostly done manually, with staff washing, soaking, disinfecting, and then drying them in water tanks in a cleaning room. This method has obvious drawbacks: it consumes a lot of time and manpower, resulting in low efficiency; the cleaning process is difficult to supervise, and the quality is uncontrollable; it requires a large area for drying, and the drying time is long; operators may be harmed by residual medicine due to prolonged contact with cleaning solutions and medicine baskets. In summary, existing methods for cleaning medicine baskets suffer from problems such as low efficiency, uncontrollable quality, large space occupation, and safety hazards, and there is an urgent need for a more efficient and safer cleaning solution. Utility Model Content

[0003] This utility model discloses an ultrasonic cleaning device with automatic material discharge to solve the above-mentioned technical problems in related technologies.

[0004] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application provides an ultrasonic cleaning device with automatic discharge, comprising: A cleaning tank having a chamber for containing cleaning fluid and having an open top, wherein an ultrasonic generator is installed inside the cleaning tank; A cleaning platform, which can be vertically lifted and suspended in the cavity of the cleaning tank, is used to hold the products to be cleaned; A buoyancy limiting mechanism is provided in the cavity of the cleaning tank to limit the position of the product during the cleaning process and keep the product submerged in the cleaning solution. The pushing device is configured to push the product away from the cleaning platform to achieve automatic discharge when cleaning is completed and the cleaning platform rises to the set discharge height; The controller is electrically connected to the ultrasonic generator, the lifting actuator of the cleaning platform, and the pushing device.

[0005] The technical solution adopted in this utility model can achieve the following beneficial effects: The ultrasonic cleaning device with automatic discharge described in this application can be used for the automatic cleaning of medicine baskets, and can be used in the entire process of automatic cleaning of medicine baskets. Specifically, it has the following advantages: (1) The ultrasonic generator installed on the cleaning tank can generate high-frequency vibrations by utilizing the cavitation effect of ultrasound, causing the cleaning fluid to form tiny bubbles that burst instantly, releasing a powerful impact force. This impact force can penetrate deep into the gaps, meshes, and other fine structures of the medicine basket, effectively removing residual medicine, stains, and other contaminants, making it more thorough than traditional manual cleaning. At the same time, the cleaning platform can be raised and lowered into the cleaning fluid, and with the buoyancy limiting mechanism, it can ensure that the medicine basket is always submerged in the cleaning fluid during the cleaning process, avoiding cleaning dead spots caused by floating and local areas not contacting the cleaning fluid, thus greatly improving the uniformity and cleanliness of the cleaning.

[0006] (2) The height-adjustable design of the cleaning platform simplifies the process of placing and removing medicine baskets to be cleaned: before cleaning, the platform can be raised to a high position to facilitate the placement of medicine baskets by operators, or the medicine baskets can be automatically placed through the pre-processing mechanism in the automatic cleaning process; during cleaning, the cleaning platform lowers to immerse the medicine baskets in the cleaning solution, eliminating the need for manual handling and soaking; after cleaning, the cleaning platform rises to the set discharge height to create conditions for automatic discharge. This design reduces the steps of manual intervention, saves operation time, and significantly improves the operation efficiency of a single cleaning operation compared to the traditional manual handling and soaking method.

[0007] (3) During ultrasonic cleaning, the cleaning fluid will be violently agitated, and the medicine basket itself will also be subject to a certain buoyancy due to its material properties. If there is no restraint, it is easy to float up and partially detach from the cleaning fluid. This buoyancy limiting mechanism can counteract buoyancy and impact force by limiting the position, ensuring that the medicine basket is always completely submerged in the cleaning fluid. This ensures that the cleaning conditions of each medicine basket are consistent, eliminates quality differences caused by positional fluctuations, is more stable than manual control, provides a guarantee for standardized and uniform cleaning, and improves process stability and controllability.

[0008] (4) When the cleaning is completed and the cleaning platform rises to the set discharge height, the pushing device can automatically push the medicine basket off the cleaning platform to achieve automatic discharge. This function completely replaces the manual material handling process, which not only reduces manpower consumption, but also avoids direct contact between operators and the freshly cleaned medicine basket and residual cleaning liquid, reducing the risk of injury from residual liquid. At the same time, automatic discharge can form a continuous automated cleaning production line with subsequent rinsing, drying and other processes, shortening the turnover time of the medicine basket after cleaning and further improving the overall efficiency of medicine basket cleaning in the static dispensing center.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] In related technologies, the medicine baskets used in compounding centers often employ a perforated mesh design with a flat mesh panel at the bottom and guardrails around the perimeter, with flanges at the top of the guardrails. This structure facilitates the loading and unloading of medicines, allows the cleaning solution to flow smoothly during ultrasonic cleaning, ensuring full contact with all parts of the medicine basket, prevents medicines from falling out through the guardrails, and reduces the overall weight of the medicine basket, making it easier to handle and clean. In terms of materials, medicine baskets are typically made of food-grade or medical-grade plastics that are resistant to chemical corrosion and have high strength, such as polypropylene (PP) or polyethylene (PE).

[0014] Please see Figures 1-9 As shown: This application provides an ultrasonic cleaning device with automatic discharge, comprising: The cleaning tank 1 has a chamber for containing cleaning fluid and has an open top structure. An ultrasonic generator 2 is installed inside the cleaning tank 1. The cleaning platform 3 is suspended vertically within the cavity of the cleaning tank 1 and is used to carry the products to be cleaned (medicine baskets). A buoyancy limiting mechanism is provided in the cavity of the cleaning tank 1 to limit the position of the product during the cleaning process, prevent the product from floating and keep it submerged in the cleaning solution; The pushing device is configured to push the product away from the cleaning platform 3 to achieve automatic discharge when the cleaning is completed and the cleaning platform 3 rises to the set discharge height; The controller is electrically connected to the lifting actuator and pushing device of the ultrasonic generator 2, the cleaning platform 3, and the ultrasonic generator 2.

[0015] In some embodiments, a discharge port 24 is provided on the upper part of one side of the cleaning tank 1, and the horizontal height of the discharge port 24 is higher than the initial working position of the cleaning platform 3. The feeding device includes: The pusher motor 7 has its output shaft connected to the pusher chain 4. The pusher plate 5 is fixed on the pusher chain 4 and is set perpendicular to the product discharge path; When the cleaning platform 3 rises to the set discharge height, the pusher motor 7 drives the pusher chain 4 to move, which in turn drives the pusher plate 5 to push the product away from the cleaning platform 3 and automatically output it through the discharge port 24. It can be understood that the differentiated design between the height of the discharge port 24 and the initial position of the cleaning platform 3 avoids cleaning fluid overflow and provides space for the pushing action. The pushing device, through the cooperation of the pusher chain 4, pusher plate 5, and pusher motor 7, can automatically push the product off the cleaning platform 3 when cleaning is complete and the cleaning platform 3 rises to the set discharge height. This design achieves automated discharge of the cleaned product, replacing the manual material handling step. This not only reduces labor costs and improves the continuity of the overall cleaning process but also avoids direct contact between operators and the product, reducing the potential harm of residual chemicals to the human body and improving operational safety. The pushing device adopts a structure and vertical layout with the pusher chain 4 and pusher plate 5 working together, so that the pushing force acts directly on the product discharge path, achieving efficient and stable automatic discharge and reducing manual intervention.

[0016] In some embodiments, the feeding device further includes a first reducer 8 and a sprocket drive assembly; The sprocket drive assembly includes: The first drive gear 32 is fixedly connected to the output shaft of the first reducer 8; The first drive shaft 19 is rotatably connected to the cleaning tank 1 and is set perpendicular to the discharge direction; The first driven gear 33 is fixedly installed at one end of the first transmission shaft 19; The closed-loop transmission chain 34 meshes between the first driving gear 32 and the first driven gear 33; The pusher chain 4 is configured in two sets and parallel to each other. The two sets of pusher chains 4 are arranged along both sides of the discharge path and are synchronously connected to the first drive shaft 19. Wherein, the first drive shaft 19 has a first drive wheel sleeved at each end of the two sets of push chains 4, and also includes a second drive wheel disposed at the extension end of the push chain 4, the push chain 4 meshing with the first drive wheel and the second drive wheel. The input end of the first reducer 8 is driven and connected to the output shaft of the pusher motor 7. The first driving gear 32 drives the first driven gear 33, the first transmission shaft 19, and the first transmission wheel to rotate through the closed-loop transmission chain 34, thereby driving the two sets of pusher chains 4 to move synchronously. It can be understood that the pusher device forms a dual-chain synchronous drive structure through the first reducer 8 and the sprocket transmission assembly, which enhances the stability and balance of the pusher process, avoids the deviation or jamming that may be caused by single-chain drive, and improves the reliability and applicability of the device.

[0017] In some embodiments, an initial feed sensor 41 is installed on the side wall of the cleaning tank 1 to detect the loading status of the product to be cleaned on the cleaning platform 3; the initial feed sensor 41 is electrically connected to the controller. It can be understood that the initial feed sensor 41 detects whether there is a product to be cleaned on the cleaning platform 1 and feeds the signal back to the controller, enabling intelligent start-stop control of the cleaning process. When the sensor detects a product, the controller can trigger the cleaning program to start, ensuring that the cleaning operation is carried out as needed; if no product is detected, the controller can instruct the equipment to be in standby mode, avoiding idling and ineffective operation when there is no material, reducing energy waste and unnecessary equipment wear, while improving the continuity and convenience of the cleaning operation through automated judgment.

[0018] In some embodiments, the cleaning platform 3 is provided with at least one cleaning station 10. The size of the cleaning station 10 is adapted to the product to be cleaned. A pair of inclined guide plates 11 are provided on both sides of the product discharge direction of each cleaning station 10 to guide product positioning and discharge. It is understood that the cleaning platform 3 is equipped with cleaning stations 10 adapted to the product size, and each cleaning station 10 has inclined guide plates 11 on both sides of the discharge direction. The technical effect is reflected in the dual function of positioning and guiding: the cleaning station 10 ensures that the product's position is relatively fixed during the cleaning process, avoiding the impact of shaking on the cleaning effect; the inclined guide plates 11 guide the product to quickly and accurately enter the position when placed, and guide the product away from the cleaning platform 3 along the extension direction of the guide plates 11 during discharge, ensuring the consistency of the discharge position, preventing product jamming, and improving the smoothness of loading, unloading, and discharge.

[0019] In some embodiments, the cleaning platform 3 is provided with two cleaning stations 10. It can be understood that by providing two cleaning stations 10, the cleaning platform 3 directly increases the number of products that can be cleaned at one time, and can process more medicine baskets in the same amount of time, which significantly improves cleaning efficiency. It can better adapt to the scenario of large usage and high turnover of medicine baskets in the static compounding center, reduce equipment running time, and reduce energy consumption.

[0020] In some embodiments, a pusher plate 42 is connected to the pusher plate 5 for each cleaning station 10 of the cleaning platform 3. It is understood that by adding the pusher plate 42 corresponding to each cleaning station 10 to the pusher plate 5, precise pushing of products from multiple stations is achieved. The pusher plate 42 can apply a pushing force independently to each cleaning station 10, avoiding pushing deviations caused by uneven product distribution or size differences, ensuring that products at each cleaning station 10 are synchronously and stably removed from the cleaning platform 3, thus improving the reliability and efficiency of automatic unloading. Furthermore, this design enhances the adaptability of the device to products of different specifications, allowing for adjustments to the position or structure of the pusher plate 42 to accommodate diverse cleaning needs. It also allows for the avoidance design of the guide plate 11.

[0021] In some embodiments, the guide plate 11 extends outward at an angle from bottom to top, forming an angle of 30° to 60° with the vertical direction. It is understood that the design of the guide plate 11 extending outward at an angle from bottom to top, forming an angle of 30° to 60° with the vertical direction, balances positioning guidance during feeding and guiding the discharge path. If the angle is too small, the guiding effect is weak, and the product is prone to jamming during placement; if the angle is too large, the positioning stability is insufficient, which may lead to product displacement during cleaning. This angle range can guide the product smoothly into position while meeting the requirements for guiding the discharge path.

[0022] In some embodiments, the guide plate 11 extends outward from bottom to top at an angle of 40° to 45° with the vertical direction.

[0023] In some embodiments, the buoyancy limiting mechanism includes limiting components for each cleaning station 10, and each set of limiting components includes: The limiting rod 13 is rotatably connected to the outside of the guide plate 11 at its middle part; The buoyancy body 14 is fixed to one end of the limiting rod 13, and its density is less than that of the cleaning fluid. The pressing end 15 is located at the other end of the limiting rod 13; When the cleaning platform 3 descends into the cleaning fluid, the buoyancy body 14 is driven by the buoyancy to rotate the limiting rod 13, so that the pressing end 15 is pressed down to the product surface to achieve the limiting. When the cleaning platform 3 rises above the liquid surface, the buoyancy body 14, under the influence of gravity, drives the limiting rod 13 to rotate in the opposite direction, and the pressing end 15 releases from the product surface, thus releasing the limiting position. It can be understood that the buoyancy limiting mechanism, through the cooperation of the limiting rod 13, the buoyancy body 14, and the pressing end 15, utilizes buoyancy and gravity to achieve automatic limiting and release: during cleaning, the buoyancy body 14 is driven by buoyancy to press the pressing end 15 down on the product, ensuring it is submerged in the cleaning solution; when rising above the liquid surface, the buoyancy body 14, under gravity, drives the pressing end 15 to release. This design requires no additional power source, relying entirely on the automatic switching between buoyancy and gravity of the cleaning solution, achieving intelligent control of "limiting during cleaning and releasing during discharge," ensuring both cleaning effectiveness and automatic discharge, thus improving the automation and energy efficiency of the equipment.

[0024] In some embodiments, an auxiliary connector 16 is provided on the outer side of the guide plate 11, and connecting rods 17 are rotatably connected to both sides of the auxiliary connector 16. The middle part of the limiting rod 13 is connected to the connecting rods 17. It is understood that by providing the auxiliary connector 16 on the outer side of the guide plate 11 and using the connecting rods 17 on both sides to achieve the rotatable connection between the limiting rod 13 and the guide plate 11, a stable mounting point for the limiting rod 13 is provided, while ensuring the flexibility of the limiting rod 13's rotation. This connection structure allows the limiting rod 13 to rotate smoothly with the force changes of the buoyancy body 14, ensuring reliable downward pressure and limiting at the pressing end 15 during cleaning and smooth release during material discharge, thus improving the operational stability and response sensitivity of the buoyancy limiting mechanism. Simultaneously, the design of the auxiliary connector 16 and the connecting rods 17 simplifies the assembly relationship between the limiting rod 13 and the guide plate 11, facilitating component installation, debugging, and subsequent maintenance.

[0025] In some embodiments, the cleaning platform 3 is an L-shaped cleaning platform 3, including a horizontal support portion 301 and a vertical connecting portion 302; the lifting actuator includes: The lifting motor 21 is fixed to the outer side wall of the cleaning tank 1; The lifting block 23 is connected to the output shaft of the lifting motor 21 via a belt drive assembly; and the lifting block 23 is connected to the upper end of the vertical connecting part 302. When the lifting motor 21 starts, it drives the lifting block 23 via the belt drive assembly, causing the L-shaped cleaning platform 3 to move vertically, thus achieving lifting control of the cleaning platform 3. It can be understood that the horizontal bearing part 301 of the L-shaped cleaning platform 3 can stably support the product to be cleaned, while the vertical connecting part 302 provides reasonable structural support for the connection with the lifting actuator, allowing the lifting force to be transmitted more evenly to the entire platform. The lifting actuator drives the lifting block 23 via the lifting motor 21 and the belt drive assembly, thereby driving the L-shaped cleaning platform 3 to rise and fall. This design not only achieves smooth lifting and lowering of the cleaning platform 3, facilitating control of product immersion and detachment in the cleaning solution, but also places the lifting motor 21 outside the cleaning tank 1, reducing the possibility of the motor coming into contact with the cleaning solution and improving the safety and durability of the equipment.

[0026] In some embodiments, a vertical guide groove 37 is formed on the side wall of the cleaning tank 1, which runs through the horizontal support portion 301 of the cleaning platform 3 along its lifting trajectory. Furthermore, an enclosing housing 38 is provided on the outer side of the corresponding vertical guide groove 37 on the side wall of the cleaning tank 1, with the top of the housing 38 higher than the maximum working surface of the cleaning fluid. It is understood that the vertical guide groove 37 on the side wall of the cleaning tank 1, running through the horizontal support portion 301 of the cleaning platform 3, is used for the lifting of the cleaning platform 3. The enclosing housing 38 prevents the cleaning fluid from overflowing through the vertical guide groove 37, reducing the impact of liquid leakage on external components and ensuring the normal operation of the lifting mechanism.

[0027] In some embodiments, the lifting actuator of the cleaning platform 3 further includes: (1) Reduction transmission assembly: The second reducer 12 is connected to the output shaft of the lifting motor 21, and its output end is coaxially fixed to the second drive gear 28; (2) Two-stage belt drive assembly: First stage of transmission: The first closed-loop belt 20 is engaged between the second driving gear 28 and the second driven gear 29, and the second driven gear 29 is coaxially fixed to the third driven gear 30 through the second transmission shaft 38; Second stage transmission: The third driven gear 30 is linked to the fourth driven gear 31 at the end through the second closed-loop belt 22; (3) Lifting and guiding actuator: Guide rails 25 are provided along the lifting direction of lifting block 23; An auxiliary connecting block 36 is provided on the lifting block 23, and a guide groove is provided on the auxiliary connecting block 36 to slide in cooperation with the guide slide rail 25. The lifting block 23 is rigidly fixed to the second closed-loop belt 22 via the connecting plate 18 and the connecting block 35. It can be understood that the cooperation between the reduction transmission assembly and the double-stage belt transmission assembly reduces the output speed of the lifting motor 21 to obtain suitable lifting power, and also achieves smooth lifting of the cleaning platform 3 through multi-stage transmission, reducing motion impact. The cooperation between the guide rail 25 and the guide groove of the lifting guide actuator further restricts the movement trajectory of the lifting block 23, ensuring the stability of the vertical lifting of the cleaning platform 3 and improving the accuracy and reliability of the overall lifting action.

[0028] In some embodiments, an auxiliary mounting frame 6 is also included, wherein the lifting motor 21 and the second reducer 12 are both located on the top of the auxiliary mounting frame 6, the second closed-loop belt 22 is located inside the auxiliary mounting frame 6, and the guide rail 25 is located on the auxiliary mounting frame 6; The auxiliary mounting bracket 6 is connected to the cleaning tank 1. It can be understood that the auxiliary mounting bracket 6 provides a unified mounting carrier for components such as the lifting motor 21 and the second reducer 12, so that the relative positions of each transmission component are fixed and the accuracy of transmission coordination is guaranteed; placing the second closed-loop belt 22 inside the mounting frame and the guide rail 25 on the mounting bracket can reduce the interference of the external environment on the transmission structure, and at the same time facilitate centralized maintenance.

[0029] In some embodiments, the auxiliary mounting bracket 6 is mounted via an external mounting bracket 41.

[0030] In some embodiments, the cleaning tank 1 is connected to an inlet pipe 26 and a drain pipe 27. It is understood that the inlet pipe 26 and drain pipe 27 on the cleaning tank 1 provide dedicated channels for the injection and discharge of cleaning fluid. The inlet pipe 26 enables automatic or convenient filling of cleaning fluid without manual emptying, reducing labor input and operational complexity; the drain pipe 27 quickly discharges used waste fluid, preventing waste fluid residue in the cleaning tank 1. The combination of these two systems makes the cleaning fluid replacement process more efficient and orderly, improving operational efficiency in the cleaning preparation and finishing stages, maintaining a clean cleaning environment, reducing the risk of manual contact with waste fluid, and further enhancing the practicality and safety of the device.

[0031] In some embodiments, an overflow pipe 9 is connected to the cleaning tank 1. It is understood that the overflow pipe 9 connected to the cleaning tank 1 allows for the timely discharge of cleaning fluid exceeding the set level, preventing overflow due to overfilling or level fluctuations during cleaning, maintaining a stable cleaning fluid level, and ensuring a clean cleaning environment. Simultaneously, the overflow process removes any impurities that may float on the surface of the cleaning fluid, reducing secondary contamination of the product and indirectly improving the cleaning effect. It also reduces the operational costs of manually monitoring the liquid level.

[0032] The working process of the ultrasonic cleaning device with automatic discharge in this application is as follows: S1. Initial preparation: A set amount of cleaning fluid is injected into the chamber of the cleaning tank 1 through the inlet pipe 26, and the liquid level does not exceed the height of the overflow pipe 9; the cleaning platform 3 is in the initial working position (the position to be fed above the liquid level of the cleaning fluid), the push plate 5 of the pusher device is in the initial standby position, and the pressing end 15 of the buoyancy limiting mechanism is in the raised state. S2. Feeding detection: Place the product to be cleaned (medicine basket) on the cleaning station 10 of the cleaning platform 3. The guide plates 11 on both sides (at an angle of 30°~60° with the vertical direction) guide the product to enter the position accurately. After the initial feeding sensor 41 detects the product, it feeds the signal back to the controller and triggers the start of the cleaning program. S3. Cleaning platform descent: The controller commands the lifting actuator (lifting motor 21, double-stage belt drive assembly, etc.) to operate, driving the horizontal bearing part 301 of the L-shaped cleaning platform 3 to descend along the vertical guide groove 37 until the product is completely submerged in the cleaning liquid; at this time, the buoyancy body 14 of the buoyancy limiting mechanism is driven by buoyancy to rotate the limiting rod 13, and the pressing end 15 presses down on the product surface to prevent it from floating. S4. Ultrasonic cleaning: The controller starts the ultrasonic generator 2, and the cleaning fluid generates ultrasonic vibration to clean the product; during the cleaning process, the overflow pipe 9 discharges excess cleaning fluid in time to maintain a stable liquid level, and the enclosure shell 38 prevents the cleaning fluid from overflowing through the vertical guide groove 37. S5. Cleaning platform rises: After cleaning is completed, the controller instructs the lifting actuator to reverse, driving the cleaning platform 3 to rise and detach from the cleaning fluid; the buoyancy body 14 drives the limit rod 13 to rotate in the opposite direction due to gravity, and the pressing end 15 is lifted, releasing the limit on the product. S6. Automatic discharge: When the cleaning platform 3 rises to the set discharge height (matching the horizontal height of the discharge port 24), the controller commands the pusher to start: the pusher motor 7 drives the two sets of pusher chains 4 to move synchronously through the first reducer 8 and the sprocket transmission assembly, driving the pusher plate 5 (and the pusher plate 42) to push the product along the discharge path; the product moves along the guide plate 11 and leaves the cleaning platform 3 through the discharge port 24, completing the automatic discharge. S7. Reset and standby: The pushing device drives the pushing plate 5 to reset to the initial standby position, and the cleaning platform 3 descends to the initial working position; if continuous cleaning is required, repeat steps S2 to S6; if cleaning is finished, the waste liquid is discharged through the drain pipe 27, and the equipment returns to the initial standby state.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
