Description

Technical Field

[0001] This invention relates to the field of cleaning machine technology, specifically a cleaning machine for the production of ultra-thin aluminum cups. Background Technology

[0002] In the metal packaging container manufacturing industry, thin-walled containers such as beverage cans and cups must undergo surface cleaning after stretch forming to remove residual lubricating oil, metal debris, and other contaminants from the forming process. This ensures the quality of subsequent drying, coating, or filling processes. Existing cleaning machines typically use a mesh belt conveyor system, allowing the cans to pass through a spray chamber sequentially, where cleaning fluid is sprayed from fixedly installed spray pipes. However, these traditional cleaning machines have a fundamental limitation in their design: the internal height of their spray chambers is basically fixed, and the distance between the pressure mesh and the cleaning mesh belt can only be slightly adjusted. Essentially, they are only suitable for cans of a single specification or similar height. This results in the equipment's limited functionality. When companies need to produce cans of different heights, they must purchase multiple dedicated cleaning machines or frequently replace core components, which not only significantly increases equipment investment costs but also seriously affects the production line's turnaround efficiency.

[0003] Further analysis reveals that because the pressure screen adjustment stroke is limited to fine-tuning, it cannot adapt to significant changes in tank height. When dealing with different cup shapes, operators often need to make adjustments manually through cumbersome methods such as disassembling and assembling shims and replacing the pressure screen. This is time-consuming, labor-intensive, and difficult to guarantee accuracy. More importantly, this structural limitation also triggers a chain reaction of cleaning quality issues. When the tank height changes, the relative position of the spray pipe and the tank surface also changes. However, the spray rinsing force of existing equipment is usually fixed or has only a very narrow adjustment range, and cannot be adaptively adjusted according to the actual height and wall thickness of the tank. For containers like ultra-thin aluminum cups with extremely thin walls and low structural strength, if the rinsing force is too strong, the high-pressure water flow will directly cause the cup to deform, dent, or even break. On the other hand, if the rinsing force is uniformly reduced to accommodate thin-walled cups, it will lead to incomplete cleaning of other conventional tanks and an increased oil residue rate. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning machine for the production of ultra-thin aluminum cups, which solves the problems of poor compatibility of the tank height, inability to adaptively adjust the rinsing force according to the thickness of the cup, and lack of stable conveying function in the existing cleaning machines.

[0019] Please see Figures 1-18 A cleaning machine for producing ultra-thin aluminum cups, including a cleaning machine base frame assembly 100; A heat circulation pump 200, a first circulation spray pump 300, a second circulation spray pump 400, and a pure water return pump 500 are sequentially arranged on the cleaning machine base frame assembly 100 along the first direction; The spray chamber assembly 600, the screen pressing assembly 900, the cleaning screen bracket 800, and the water tank assembly 700 are sequentially arranged on the cleaning machine base frame assembly 100 along the second direction; The cleaning machine base frame assembly 100 serves as the load-bearing and installation foundation for the entire cleaning machine, providing a stable support platform for all other components. The heat circulation pump 200, the first circulating spray pump 300, the second circulating spray pump 400, and the pure water return pump 500 provide power for the circulation of heated cleaning fluid, the liquid delivery for the first spray rinse, the liquid delivery for the second fine spray, and the power for pure water recycling, respectively. The four pumps work together to achieve multi-stage, adjustable-intensity rinsing effects. The cleaning machine also includes a spray chamber assembly 600, a screen pressing assembly 900, a cleaning screen bracket 800, and a water tank assembly 700. The spray chamber assembly 600 forms a closed cleaning chamber and provides mounting positions for the spray nozzles. The screen pressing assembly 900 holds the ultra-thin aluminum cups from above to prevent them from shifting or floating during cleaning. The cleaning screen bracket 800 carries and transports the aluminum cups through various workstations. The water tank assembly 700 collects and filters the cleaning fluid for reuse.

[0020] Specifically, the cleaning machine base frame assembly 100 includes a frame mechanism 110 and a guide mechanism 120, with the guide mechanism 120 disposed on the frame mechanism 110 along a first direction; The frame mechanism 110 includes a rectangular tube 111, a side plate 112 fixedly installed on the surface of the rectangular tube 111 along the second direction, a water pump mounting plate 113 fixedly installed on the surface of the rectangular tube 111 along the second direction, a support shaft 114 provided on the surface of the rectangular tube 111 along the third direction, a roller 115 provided on the surface of the rectangular tube 111 along the third direction, the support shaft 114 and the roller 115 are arranged sequentially along the first direction, and a screw seat 116 fixedly installed on the surface of the rectangular tube 111 along the second direction. The frame mechanism 110 is used to construct the skeleton of the base frame and install various support plates and rollers. The guide mechanism 120 is used to guide the cleaning mesh belt to run smoothly in the first direction and prevent deviation. The rectangular tube 111 is used as the main skeleton of the frame mechanism 110, providing a basic support structure and installation benchmark. The side plate 112 is used to close the side of the frame and enhance the overall rigidity, while providing a vertical mounting surface for subsequent installation of components such as the spray chamber. The water pump mounting plate 113 is used to support and fix the heat circulation pump 200, ensuring that the pump unit is installed accurately and the force is evenly distributed. The support shaft 114 is used to provide a rotation fulcrum or tension point. The roller 115 is used to support and guide the cleaning mesh belt to run smoothly and reduce friction and wear. The screw seat 116 is used to provide an anchor point for bolt connection, which facilitates detachable fixing with other components.

[0021] Specifically, the guide mechanism 120 includes a channel steel 121, a mesh belt return bar 122 is fixedly installed on the surface of the channel steel 121 along the second direction, and a mesh belt stop block 123 is fixedly installed on the surface of the channel steel 121 along the second direction; By setting channel steel 121 as the main support component of guide mechanism 120, a rigid guide rail base extending in the first direction is provided, and its surface in the second direction provides a flat mounting plane for subsequent installation of other guide elements. By setting mesh belt return bar 122, the mesh belt is guided to return smoothly to the starting end after completing the conveying stroke, avoiding mesh belt sagging or deviation, and ensuring the stability of mesh belt circulation operation. By setting mesh belt stop 123, physical limits are formed on both sides or key positions of mesh belt running path to prevent excessive lateral deviation of mesh belt and prevent mesh belt from interfering with or derailing with adjacent components.

[0022] Specifically, the spray chamber assembly 600 includes a spray frame mechanism 610, a drain plate 620, and a drainage mechanism 630. The spray frame mechanism 610 is fixedly installed on the surface of the frame mechanism 110 along the second direction, the drain plate 620 is disposed on the spray frame mechanism 610 along the second direction, and the drainage mechanism 630 is disposed on the spray frame mechanism 610 along the second direction. The spray frame mechanism 610 serves as the overall frame of the spray chamber, providing a stable installation base for the spray nozzles, pipes, and sealing panel 616, while enclosing and forming a closed cleaning chamber. The drain plate 620 is used to collect the cleaning liquid dripping after spraying and guide the liquid to a designated flow direction, while allowing air circulation to accelerate the drying process on the surface of the aluminum cup and prevent water accumulation. The drainage mechanism 630 is used to quickly discharge the waste liquid collected by the drain plate 620 from the spray chamber, preventing liquid overflow and maintaining the cleanliness of the cleaning environment.

[0023] Specifically, the spray frame mechanism 610 includes a base 611, a water receiving tray side plate 612 fixedly installed on the surface of the base 611 along the first direction, a wall panel 613 fixedly installed on the surface of the base 611 along the first direction, a support 614 fixedly installed on the surface of the wall panel 613 along the second direction, an upper beam 615 fixedly installed on the surface of the base 611 along the second direction, a panel 616 fixedly installed between the base 611 and the upper beam 615, an end panel 617 fixedly installed between the base 611 and the upper beam 615, and a baffle 618 fixedly installed on the surface of the end panel 617 along the first direction. The base 611 serves as the bottom load-bearing base of the spray frame mechanism 610, providing a stable horizontal installation reference for the entire spray frame mechanism 610. The water receiving tray side plates 612 form water-retaining facades on both sides of the spray frame, preventing cleaning fluid from splashing out and guiding water flow into the drainage area below. The wall panels 613 form the front and rear main walls of the spray chamber, providing an enclosed cleaning space and enhancing the torsional rigidity of the overall structure. The braces 614 form lateral supports between the wall panels 613. To prevent the wall panel 613 from deforming or bulging under the pressure of the spray water, an upper beam 615 is provided as a horizontal connector at the top of the spray frame, forming a closed frame corresponding to the base 611. A panel 616 is provided to close the side openings of the spray chamber, forming a complete heat and water barrier. An end panel 617 is provided to close the two end openings of the spray chamber, ensuring the airtightness of the cleaning chamber. A baffle 618 is provided to form a partial shield at the inlet and outlet, preventing the cleaning liquid from splashing out from the end.

[0024] Specifically, the drainage mechanism 630 includes an elbow 631 and a seamless pipe 632. The elbow 631 is fixedly installed on the surface of the drain plate 620 along the second direction, and the seamless pipe 632 is fixedly installed at the end of the elbow 631. By setting an elbow 631 as a turning connector for the drainage pipe, the cleaning liquid collected by the drain plate 620 is guided from the horizontal direction to the vertical or inclined direction, changing the water flow path to adapt to the pipe layout under the base frame. By setting a seamless pipe 632 as a main drainage pipe, the cleaning liquid is quickly and smoothly delivered to the sink assembly 700 or the external drainage system.

[0025] Specifically, the water tank assembly 700 includes a tank body 710 and an overflow tank 720. The overflow tank 720 is opened on the surface of the tank body 710 along a third direction. A water pump support plate 730 is fixedly installed on the surface of the tank body 710 along a second direction. A filter mechanism 740 is arranged inside the tank body 710 along the second direction. A drain pipe 750 is fixedly installed on the surface of the tank body 710 along a first direction. A mudguard 760 is arranged inside the tank body 710. A filter screen 770 is arranged inside the tank body 710. A water tank cover 780 is arranged on the surface of the tank body 710 along the second direction. The tank 710 serves as the main container of the water tank assembly 700, storing and holding the circulating cleaning fluid used during the cleaning process, and providing installation space and support for other internal components. The overflow tank 720 automatically overflows excess liquid when the liquid level exceeds a set height, preventing excessive pressure or liquid spillage within the tank 710 and guiding floating oil or light impurities out with the overflow. The pump support plate 730 provides independent mounting supports for each circulating pump, ensuring a stable connection between the pump unit and the tank 710, and facilitating pump inspection and maintenance. The filter mechanism 740 filters the returned cleaning fluid. The system employs a multi-stage filtration system to intercept solid particles and ensure the cleanliness of the circulating liquid. A drain pipe 750 is installed to completely discharge wastewater to an external pipeline when the cleaning liquid needs to be replaced or the tank 710 needs to be cleaned. A mudguard 760 is installed to prevent sediment or heavier particles from being resuspended under the disturbance of the liquid flow, guiding impurities to settle in a specific area at the bottom of the tank for easy centralized cleaning. A filter screen 770 is installed to coarsely filter the cleaning liquid before it enters the pump unit, preventing large particles from damaging the pump impeller or clogging the spray nozzles. A water tank cover 780 is installed to seal the top opening of the tank 710, preventing external debris from falling into the tank and reducing the evaporation of the cleaning liquid and heat loss.

[0026] Specifically, the filtration mechanism 740 includes a hinge 741, one end of which is fixedly installed in the tank 710. A crossbar 742 is fixedly installed on the surface of the tank 710 along the second direction. A filter screen groove 743 is fixedly installed on the surface of the crossbar 742 along the first direction. A filter residue screen 744 is slidably connected in the filter screen groove 743 along the second direction. By setting a hinge 741 as a connectable component for the filter screen 743, the filter screen 743 can be flipped upwards around the axis of the hinge 741, facilitating daily cleaning and maintenance of the filter screen 744. By setting a crossbar 742 as a horizontal support beam for the filter screen 743, a stable mounting base is provided for the filter screen 743, and the positioning accuracy of the filter screen 743 within the tank body 710 is ensured. By setting a filter screen 743 as a frame structure to accommodate the filter screen 744, a fixed filtration channel is formed, guiding all the cleaning liquid to flow through the filter screen 744 for filtration. By setting a filter screen 744 as a removable filter element, solid contaminants in the cleaning liquid are intercepted, while allowing the operator to easily remove the filter screen 744 for cleaning or replacement without disassembling the overall structure.

[0027] Specifically, the screen pressing assembly 900 includes a screen pressing 910 and a lifting mechanism 920. The lifting mechanism 920 is arranged in the spray chamber assembly 600 along the second direction, and the screen pressing 910 and the lifting mechanism 920 are arranged sequentially along the second direction. By setting up a pressure mesh 910, which serves as a flexible pressure element that directly contacts and presses down on the ultra-thin aluminum cup, a uniform downward pressure is applied over the aluminum cup to prevent it from shifting or floating due to water flow impact during the spray rinsing process, thus ensuring the accuracy of cleaning positioning. By setting up a lifting mechanism 920, a controllable lifting driving force is provided for the pressure mesh 910.

[0028] Specifically, the lifting mechanism 920 includes a lifting platform 921 and a mesh belt support bar 922. The lifting platform 921 is fixedly installed on the surface of the spray chamber assembly 600 along a third direction. The mesh belt support bar 922 is fixedly installed on the pressure mesh 910. An installation plate 923 is fixedly installed on the surface of the mesh belt support bar 922 along a third direction. A connecting shaft 924 is provided on the surface of the installation plate 923 along a first direction. A commutator 925 is provided at the end of the connecting shaft 924. A reduction gearbox 926 is provided on the commutator 925. A handwheel 927 is provided on the reduction gearbox 926. By setting up a lifting platform 921, which serves as the core actuator of the lifting mechanism 920, the input rotational motion is converted into linear lifting motion, driving the connected pressure mesh 910 to move precisely in the second direction. By setting up a mesh belt support bar 922, which serves as an intermediate transition connecting the pressure mesh 910 and the lifting transmission system, it also provides support and guidance for the cleaning mesh belt, ensuring that the mesh belt remains straight during the lifting of the pressure mesh 910. By setting up a mounting plate 923, which serves as a mounting base for the connecting shaft 924 and other transmission components, it provides a stable mounting surface. By setting up the connecting shaft 924, it transmits the power from... The torque of the commutator 925 is transmitted to the lifting mechanism 921, enabling long-distance power transmission. By setting the commutator 925, the transmission direction is changed, converting the rotation input by the handwheel 927 perpendicular to the first direction into rotation parallel to the first direction to adapt to installation space limitations. By setting the reduction gearbox 926, the input speed of the handwheel 927 is reduced and the output torque is increased, allowing the operator to obtain a larger lifting driving force with a smaller force of the handwheel 927, while improving the precision of lifting control. The handwheel 927 is set as an input interface for manual operation, allowing the operator to rotate it to drive the entire lifting transmission chain.

[0029] The specific implementation process of this invention is as follows: The ultra-thin aluminum cup is placed on the cleaning mesh support 800, carried by the cleaning mesh belt and conveyed along the first direction. During operation, the mesh belt is constrained by the guiding mechanism 120, the channel steel 121 provides a rigid guide rail, the mesh belt return bar 122 supports the return section of the mesh belt to ensure smooth operation, and the mesh belt stop block 123 provides lateral limit to prevent deviation. When the mesh belt passes through the interior of the spray chamber assembly 600 in sequence, the mesh pressing assembly 900 begins to intervene in positioning. The operator rotates the handwheel 927 according to the cup height. The rotational torque of the handwheel 927 is reduced and amplified by the gearbox 926 and then transmitted to the commutator 925. The commutator 925 changes the direction of the rotation axis and transmits the power to the elevator 921 through the connecting shaft 924. The elevator 921 converts the rotational motion into linear motion, pushing the mesh belt support 922 and the pressure mesh 910 fixed thereto to descend in the second direction until the pressure mesh 910 contacts and presses the top of the aluminum cup, so that the aluminum cup is firmly restricted between the cleaning mesh support 800 and the pressure mesh 910, preventing displacement or floating during spraying. After the aluminum cup enters the spray chamber assembly 600, the four pump sets start working in sequence. The hot circulation pump 200 first draws the heated cleaning liquid from the water tank assembly 700 and sends it through the pipeline to the nozzles in the spray chamber to preheat and initially rinse the aluminum cup, softening the surface deposits. Then, the first circulation spray pump 300 and the second circulation spray pump 400 start in sequence, providing cleaning liquid with different pressures and flow rates to perform multi-angle and multi-layer fine spraying and rinsing of the inner and outer surfaces of the aluminum cup. The working pressure of each pump can be independently adjusted according to process requirements, thereby flexibly adjusting the rinsing force and avoiding damage to the thin-walled cup body. The pure water return pump 500 intervenes at the end to recover the low-concentration waste liquid generated after pure water spraying to the water tank assembly 700, realizing the recycling of water resources. Throughout the spraying process, the closed cavity of the spray chamber assembly 600 effectively constrains the water flow direction and prevents liquid splashing. After spraying, the cleaning liquid drips onto the drain plate 620 under gravity. The drain plate 620 is inclined along the second direction, so that the liquid gathers along the plate surface to the drain outlet. The gathered waste liquid changes the flow direction through the elbow 631 and is quickly discharged from the spray chamber through the seamless pipe 632 and transported to the water tank assembly 700. The combination of the elbow 631 and the seamless pipe 632 ensures unobstructed drainage, avoids water accumulation in the spray chamber, and prevents the aluminum cup from being contaminated secondary. After the waste liquid enters the water tank assembly 700, it first passes through the overflow tank 720 to stabilize the liquid level. Excess liquid or floating oil overflows from here. Then, the liquid undergoes multiple purification processes inside the tank body 710: the mudguard 760 prevents heavier particles from being resuspended under the disturbance of the liquid flow, guiding impurities to settle at the bottom of the tank; the filter screen 770 performs coarse filtration to intercept large particles of impurities; finally, the liquid flows through the filter mechanism 740, where the filter screen groove 743 supported by the crossbar 742 contains a removable filter screen 744 to perform fine filtration of the cleaning liquid, completely intercepting solid particles. The purified cleaning liquid collects at the bottom of the tank body 710 and is re-extracted by the circulation pumps installed on the water pump support plate 730 and sent to the spray system to form a closed loop circulation. The water tank cover 780 is closed throughout the process to prevent external debris from falling in and to reduce liquid evaporation and heat loss. When it is necessary to discharge sewage or replace the cleaning liquid, the drain pipe 750 can be opened to completely discharge the sewage in the tank. After a cleaning cycle is completed, the lifting mechanism 920 reverses its direction, and the lifting platform 921 drives the pressure screen 910 to rise and reset, releasing the cleaned aluminum cups. The mesh belt continues to transport the aluminum cups forward, moving them out of the spray chamber. At the same time, the next batch of aluminum cups to be cleaned enters the spray chamber to start a new cycle. For cups of different heights, the operator only needs to readjust the handwheel 927 to change the height of the pressure screen 910 to quickly adapt, without replacing any hardware. The entire equipment achieves non-destructive, efficient, and residue-free cleaning of ultra-thin aluminum cups through the coordinated operation of pump pressure regulation, pressure screen 910 height adjustment, multi-stage filtration circulation, and a closed spray chamber, meeting the process requirements of multi-variety compatible production.
