[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0018] This embodiment describes a device for removing impurities from an aluminum-plastic composite cap, which relates to the field of medical aluminum cap production technology. The device includes a rolling screening component 100 to remove impurities from the aluminum cap, a spraying component 200 to clean the aluminum cap in real time and unclog the mesh cylinder 110, a drying component 300 to quickly dry the aluminum cap, and a packaging component 400 to collect aluminum shavings. This device solves the problems of impurity residue, screen blockage, and aluminum powder explosion, and has the advantages of high efficiency, cleanliness, safety, and reliability.

[0019] Please see Figures 1 to 8 The impurity removal device for an aluminum-plastic composite cap in this embodiment includes: a rolling screening component 100, a spraying component 200, and a drying component 300. The rolling screening component 100 can initially separate the aluminum cap from the impurities, the spraying component 200 can remove the impurities attached to the aluminum cap and the mesh cylinder 110, and the drying component 300 can dry the aluminum cap.

[0020] The rolling screening assembly 100 includes a screen cylinder 110 and a rotating shaft 120. The rotating shaft 120 is inserted into the screen cylinder 110 and is connected to the screen cylinder 110 through a bracket. The relative rotation of the rotating shaft 120 can drive the screen cylinder 110 to rotate, thereby driving the aluminum cover located in the screen cylinder 110 to roll relative to each other, separating the aluminum cover and the debris.

[0021] The spray assembly 200 includes multiple nozzles 210 mounted on the rotating shaft 120. The nozzles 210 spray water relative to the inner wall of the mesh cylinder 110, effectively flushing away debris from the aluminum cover surface, reducing aluminum shavings adhering to the inner wall of the mesh cylinder 110, and preventing mesh clogging through dynamic spraying. This also reduces downtime caused by nozzle 210 maintenance. The water cools the aluminum debris and isolates it from oxygen, eliminating safety hazards.

[0022] The air-drying component 300 is located on one side of the mesh cylinder 110 and can supply air to the inside of the mesh cylinder 110 to quickly dry the aluminum cover and prevent the wet aluminum cover from oxidizing in subsequent processes.

[0023] During use, the aluminum cap enters the rotating screen cylinder 110 and tumbles with the cylinder, separating and dropping impurities smaller than the screen holes. As the rotating shaft 120 drives the screen cylinder 110 to rotate, the nozzles 210 continuously spray water to wash the surface of the aluminum cap, removing attached aluminum shavings while rinsing the screen holes to prevent clogging. After cleaning, the aluminum cap moves to the end of the screen cylinder 110, where the airflow generated by the fan 310 blows against the direction of airflow onto the surface of the aluminum cap, accelerating moisture evaporation and achieving a drying process.

[0024] It should be noted that the mesh cylinder 110 is a cylindrical structure with sieve holes, which can be made of stainless steel woven mesh. The diameter of the sieve holes is set according to the size of the aluminum cap, and it is used to separate the aluminum cap from impurities during rotation.

[0025] In some embodiments, please refer to Figure 4 The rotating shaft 120 is hollow, forming an internal cavity for conveying purified water. The nozzles 210 are detachably connected to the rotating shaft 120 and can communicate with the cavity to deliver purified water. Multiple nozzles 210 are equidistantly arranged in a ring array around the central axis of the rotating shaft 120, and these ring arrays are equidistant along the length of the rotating shaft 120. The internal channels of the rotating shaft 120 and the ring array of nozzles 210 create a three-dimensional scouring effect as the water flows with the rotation of the shaft 120, enhancing the scouring effect on the surface of the aluminum cover, reducing the adhesion of aluminum shavings to the inner wall of the mesh cylinder 110, and preventing mesh clogging through dynamic spraying.

[0026] In practical implementation, the rotating shaft 120 has a through-channel structure inside, which can be formed by machining metal tubing, for conveying clean water to the spray heads 210. The spray heads 210 are fixed to the rotating shaft 120 by threads or snap-fit ​​connections, which can be achieved using quick-release couplings for easy maintenance or replacement of clogged spray heads 210. The spray heads 210 located on the same cross-section are evenly distributed along the circumference, which can be achieved using machined positioning holes to ensure uniform spray coverage. The spray head groups 210 are arranged at fixed intervals along the axial direction of the rotating shaft 120, which can be achieved using a standardized spacing layout to ensure thorough cleaning without blind spots. When the rotating shaft 120 rotates, the annular array of nozzles 210 rotates synchronously with the shaft 120, and the sprayed water jets dynamically cover and impact the inner wall of the mesh cylinder 110 and the surface of the aluminum cover. Multiple annular nozzles 210 groups, equidistantly arranged along the length of the rotating shaft 120, can simultaneously act on different areas, avoiding incomplete cleaning due to uneven water flow distribution. The detachable design of the nozzles 210 facilitates quick replacement in case of blockage, preventing excessive downtime and reducing efficiency.

[0027] In some embodiments, please refer to Figures 2 to 5 The spray assembly 200 also includes a water supply unit 220, which includes a sealed bearing 221 and a water supply pipe 222 for supplying clean water. The inner ring of the sealed bearing 221 is connected to the end of the rotating shaft 120, and the outer ring of the sealed bearing 221 is connected to the frame. The water supply pipe 222 is connected to the sealed bearing 221. Through the water delivery channel inside the rotating shaft 120 combined with the rotary sealing structure, the spray head 210 rotates synchronously with the screen cylinder 110, achieving full-circumference spraying without dead angles. At the same time, the sealed bearing 221 effectively prevents high-pressure water leakage, ensuring the stability of the water supply system.

[0028] In practical implementation, the sealed bearing 221 is a bearing structure that enables a sealed connection between the rotating and stationary components. This can be achieved using a mechanical seal or a rotary joint. Its inner ring is assembled to the end of the rotating shaft 120, and its outer ring is fixed to the frame via a flange. This allows the rotating shaft 120 to rotate freely while preventing water leakage. The water supply pipe 222 is a pipeline structure used to transport cleaning water. It can be implemented using a stainless steel corrugated pipe or a PVC rigid pipe. One end connects to an external water source, and the other end communicates with the inner cavity of the rotating shaft 120 through the axial through-hole of the sealed bearing 221, forming a closed water supply channel.

[0029] When the rotating shaft 120 rotates under the drive unit 130, the outer ring of the sealed bearing 221 remains stationary, while the inner ring rotates synchronously with the rotating shaft 120. The water supply pipe 222 continuously injects clean water into the inner cavity of the rotating shaft 120 through the axial channel of the sealed bearing 221. The clean water flows along the inner cavity of the rotating shaft 120 to each nozzle 210, where it forms a high-pressure water mist under centrifugal force and sprays it onto the inner wall of the mesh cylinder 110. This water supply method can maintain stable water delivery even when the rotating shaft 120 is rotating at high speed, avoiding the problem of water supply pipe 222 entanglement that exists in traditional external spraying.

[0030] In some embodiments, please refer to Figure 2 and Figure 7The rolling screening assembly 100 also includes a drive unit 130, which includes a drive motor 131 and a transmission component 132. The two ends of the transmission component are connected to the drive motor 131 and the rotating shaft 120, respectively. The drive motor 131 can drive the rotating shaft 120 to rotate via the transmission component 132, thereby driving the entire screen cylinder 110 to rotate. Simultaneously, by setting the transmission component 132 to adjust the output speed of the drive motor 131, the rotation speed of the screen cylinder 110 can be dynamically adjusted according to the size of the aluminum cap and the impurity content, ensuring effective separation under different working conditions. In practical implementation, the drive motor 131 is a device that outputs rotational power, which can be implemented using an AC asynchronous motor or a servo motor, to provide a power source for the rotational movement of the mesh cylinder 110. The transmission component 132 is a power transmission mechanism, which can be implemented using a pulley set, sprocket set, gearbox, or coupling, to transmit the output torque of the drive motor 131 to the rotating shaft 120, while adjusting the speed and torque matching requirements.

[0031] When the drive motor 131 starts, the transmission component 132 transmits rotational kinetic energy to the rotating shaft 120, causing the mesh cylinder 110 to rotate continuously around its own axis. During the rotation of the mesh cylinder 110, the aluminum cover and the inner wall of the mesh cylinder 110 generate relative motion. The aluminum shavings attached to the surface of the aluminum cover are detached under the action of centrifugal force. At the same time, the rotational motion of the mesh cylinder 110 causes the aluminum cover to flip continuously, preventing the aluminum shavings from accumulating in local areas. In some embodiments, please refer to Figure 2 and Figure 5 The air-drying component 300 includes a fan 310. The inner wall of the mesh cylinder 110 is inclined at one end to form a discharge port. The fan 310 is positioned opposite to the discharge port. The moving direction of the aluminum cover is opposite to the output direction of the fan 310. The reverse airflow can prolong the contact time between the aluminum cover and the airflow. The inclined discharge port structure ensures that the aluminum cover is always exposed to the airflow coverage during the movement, effectively solving the problems of aluminum shavings adhesion and moisture residue. In practical implementation, the fan 310 is a power device that generates airflow through rotating blades. It can be either a centrifugal fan or an axial flow fan 310, used to accelerate the evaporation of moisture from the aluminum cap surface. The discharge port is an inclined opening structure formed at the end of the mesh cylinder 110, which can be adjusted by changing the inclination angle of the inner wall of the mesh cylinder 110, guiding the aluminum cap to slide out naturally under gravity. A manual gate can be installed at the discharge port to obstruct the output of the aluminum cap, preventing the sprayed aluminum cap from being directly discharged.

[0032] The drying method, in which the airflow direction of the fan 310 is opposite to the movement direction of the aluminum cover, can be achieved by adjusting the installation position and air delivery angle of the fan 310, in order to extend the residence time of the aluminum cover in the airflow. After the aluminum cap has been sprayed and cleaned inside the mesh cylinder 110, it gradually moves towards the discharge port as the cylinder rotates. The inclined structure of the inner wall of the mesh cylinder 110 causes the aluminum cap to slide automatically towards the discharge port under gravity. At this time, the airflow generated by the blower 310 blows into the mesh cylinder 110 from the outside of the discharge port in the opposite direction. The airflow and the direction of movement of the aluminum cap form a counter-current, and the moisture on the surface of the aluminum cap is quickly removed under the impact of the airflow. At the same time, the airflow blows off the residual aluminum shavings attached to the surface of the aluminum cap. Because the airflow direction is opposite to the direction of movement of the aluminum cap, the aluminum cap is continuously subjected to the airflow during the process of sliding out of the mesh cylinder 110, thus improving the drying efficiency. In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 A device for removing impurities from an aluminum-plastic composite cover also includes an encapsulation component 400. The encapsulation component 400 includes a housing 410 enclosing the mesh cylinder 110 and a sedimentation tank 420, with the sedimentation tank 420 located at the bottom of the housing 410. The housing 410 confines aluminum shavings generated during spray cleaning within a closed space, preventing them from accumulating around the equipment and posing a fire hazard. The sedimentation tank 420 collects the aluminum shavings, reducing the risk of explosion due to shaving accumulation. Simultaneously, the sedimentation tank 420 effectively separates aluminum shavings from wastewater, preventing them from adhering to the equipment surface or drifting into the external environment, while also reducing the frequency of manual cleaning.

[0033] In the specific implementation process, the outer shell 410 is a closed structure surrounding the mesh cylinder 110, which can be achieved by welding metal plates to form a cylindrical frame, preventing aluminum shavings from scattering into the external environment during the screening process. The sedimentation tank 420 is a container located at the bottom of the outer shell 410, which can be made of stainless steel and equipped with a filter screen, used to receive aluminum-containing wastewater generated by spray cleaning, and to separate the aluminum shavings by gravity sedimentation. While the screen cylinder 110 is rotating and screening the aluminum cover, the spray assembly 200 continuously sprays water into the interior of the screen cylinder 110. The water flow carries the detached aluminum shavings along the inner wall of the screen cylinder 110 into the bottom of the outer casing 410. The sedimentation tank 420 guides the water flow to slow it down by tilting its bottom surface. Due to the density difference, the aluminum shavings gradually settle to the bottom of the tank, while the clean water is discharged through the overflow port. A sealing cover is installed on the top of the outer casing 410 to prevent the aluminum shavings from spreading into the external space under the action of airflow.

[0034] In some embodiments, please refer to Figure 7 and Figure 8 An exhaust pipe 411 is provided at the top of the casing to ensure that the gas output by the fan 310 is discharged in a timely manner, preventing obstruction of airflow. This design eliminates the problem of gas and moisture accumulation inside the enclosed cleaning equipment, reduces the safety hazard of aluminum shavings suspending and accumulating inside the casing, ensures that the cleaning process is carried out in a well-ventilated environment, and improves the stability and safety of equipment operation.

[0035] In practical implementation, the shell is the outer shell 410 structure used to enclose the mesh cylinder 110. It can be made of welded or assembled metal plates and is used to seal the mesh cylinder 110 and prevent water mist and aluminum shavings from splashing during the cleaning process. The exhaust pipe 411 is a pipe structure installed on the top of the shell. It can be a vertically or inclined metal pipe or plastic pipe and is used to exhaust the gas and moisture generated inside the mesh cylinder 110 to the external environment.

[0036] During the cleaning and drying process, water vapor, volatile substances, and fine aluminum shavings may accumulate inside the mesh cylinder 110. The exhaust pipe 411 is connected to the inside of the housing through a top opening. During equipment operation, the internal airflow carrying moisture and suspended matter flows upward and is discharged through the exhaust pipe 411. A maintenance door 412 is provided on one side of the casing, allowing for convenient internal cleaning and component maintenance of the aluminum cover cleaning device during long-term use. This ensures continuous and efficient operation of the equipment and reduces safety hazards caused by aluminum shavings accumulation. Compared with existing technologies, the casing 410 of traditional rotary drum screen equipment is usually a fully enclosed structure, requiring complete disassembly of the casing 410 for maintenance, resulting in prolonged downtime and complex operation. This solution, by adding a maintenance door 412 to the side of the casing, enables rapid completion of daily maintenance and cleaning, significantly reducing maintenance time and lowering the risk of component wear caused by frequent disassembly of the casing 410.

[0037] The access door 412 is connected to the side wall of the housing via hinges or slide rails. The door panel size can be adjusted according to the size of the housing opening, for example, a width of 300-500 mm and a height of 600-800 mm. When it is necessary to clean aluminum shavings adhering to the inner wall of the mesh cylinder 110 or unclog the spray nozzles 210, operators can open the access door 412 to directly enter the housing for operation without disassembling the entire housing 410 structure. Furthermore, the access door 412 can be secured with a latch or bolts when closed, ensuring that the door panel will not be accidentally opened due to vibration during equipment operation, thereby maintaining the stability of the internal airflow and the spray system.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
