Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 Reference Figure 1-7This embodiment provides an automatic cleaning device for empty cans, including a cleaning platform 1. The cleaning platform 1 has a soaking tank 2 and a spray trough 3 arranged side-by-side on its upper surface. The spray trough 3 extends vertically through the cleaning platform 1. A back plate 4 is fixedly connected to the upper surface of the cleaning platform 1 near the rear side. A travel cavity 8 is formed within the back plate 4. A transverse groove 9, penetrating the travel cavity 8, is formed on the front surface of the back plate 4 near the upper end. A guide rail 14 is slidably installed within the travel cavity 8. A slide block 16 is slidably connected within the guide rail 14. Support arms 17 are fixedly connected to both ends of the front surface of the slide block 16. One end of each support arm 17 extends through the transverse groove 9 to the upper part of the soaking tank 2 outside the travel cavity 8. A connecting arm 20 is fixedly connected to the lower end of each support arm 17. A metal mesh frame 21 is fixedly connected to the lower end of each connecting arm 20.

[0024] Example 2 Reference Figure 1-7 This embodiment is based on the previous embodiment, but differs in that a reciprocating screw 15 is rotatably installed inside the guide rail 14, the slide block 16 is threadedly connected to the reciprocating screw 15, a motor 18 is fixedly installed at one end of the guide rail 14, the output shaft of the motor 18 is fixedly connected to the reciprocating screw 15, the motor 18 is electrically connected to an external controller, and the external controller starts the motor 18 to drive the reciprocating screw 15 to rotate, thereby causing the slide block 16 to move laterally inside the guide rail 14, thereby driving the metal mesh frame 21 to move laterally. An electric telescopic rod 19 is fixedly installed at the center of the upper surface of the back plate 4. The piston rod of the electric telescopic rod 19 extends through the stroke cavity 8 and is fixedly connected to the upper surface of the guide rail 14. The electric telescopic rod 19 is electrically connected to an external controller. The electric telescopic rod 19 is activated by the external controller to drive the guide rail 14 to slide up and down in the stroke cavity 8, thereby driving the metal mesh frame 21 to move up and down. The front surface of the back plate 4, near the soaking tank 2, has vertical through grooves 10 and 11 that extend into the travel cavity 8. The front surface of the back plate 4, near the spray tank 3, has vertical through grooves 12 and 13 that extend into the travel cavity 8. Vertical through grooves 10, 11, 12, and 13 are all interconnected with the transverse through groove 9. The guide rail 14 is moved up and down by the electric telescopic rod 19, so that the support arm 17 can move up and down synchronously within the housing through the vertical through grooves 10, 21, 32, and 4, thereby allowing the metal mesh frame 21 to be placed into the soaking tank 2 and the spray tank 3. A guide rail 22 is provided on the inner wall of the spray tank 3 near the soaking tank 2. A reciprocating screw 23 is rotatably installed inside the guide rail 22. A slider 24 is threadedly connected to the outer wall of the reciprocating screw 23. The slider 24 is slidably connected to the inner wall of the guide rail 22. A fixing ring 25 is fixedly connected to the front end of the slider 24. A main water pipe 26 is fixedly connected inside the fixing ring 25. An upper spray pipe 27 is fixedly connected to the upper end of the main water pipe 26. A lower spray pipe 28 is fixedly connected to the lower end of the main water pipe 26. The main water pipe 26, the upper spray pipe 27, and the lower spray pipe 28 are combined to form a U-shaped spray device. The main water pipe 26 is connected to an external water source. Several spray holes are equally spaced on the lower outer wall of the upper spray pipe 27 and the upper outer wall of the lower spray pipe 28, so that the U-shaped spray device composed of the main water pipe 26, the upper spray pipe 27, and the lower spray pipe 28 can spray water from both the top and bottom. The cleaning platform 1 has a machine compartment 29 at its rear end. A second motor 30 is fixedly installed in the machine compartment 29. The output shaft of the second motor 30 is fixedly connected to a reciprocating lead screw 23. Support legs 5 are fixedly connected to the lower end of the cleaning platform 1 near the four corners. A water collection tank 6 is fixedly connected to the lower end of the support legs 5. Support feet 7 are fixedly installed to the lower end of the water collection tank 6 near the four corners. The second motor 30 is electrically connected to an external controller. The second motor 30 is started by the external controller, which drives the reciprocating lead screw 23 to rotate, thereby driving the U-shaped spray device composed of the main water pipe 26, the upper spray pipe 27 and the lower spray pipe 28 to move back and forth. When the metal mesh frame 21 is placed in the spray tank, it can be sprayed with water up and down in a back-and-forth cycle, and the wastewater is collected by the water collection tank 6 below.

[0025] Working principle: The empty can to be cleaned is placed upside down in the metal mesh frame 21. The electric telescopic rod 19 is activated via an external controller, causing the guide rail 14 to move downwards within the travel chamber 8. The metal mesh frame 21 is then placed into the soaking tank 2 through the vertical through-slots 10 and 11. The empty can is soaked in the soaking tank 2 for a period of time to soften and dissolve the stains. The soaking solution can be selected according to the type of stains on the empty can to achieve the best cleaning effect. After soaking, the electric telescopic rod 19 is activated again to lift the metal mesh frame 21 out of the soaking tank 2. The external controller starts motor 18, which drives the reciprocating screw 15 to rotate, thereby moving the slide block 16 and moving the metal mesh frame 21 to one side above the spray tank 3. The metal mesh frame 21 is then placed into the spray tank 3 through the vertical through-slots 12 and 13. At the same time, the external controller starts motor 30, which drives the reciprocating screw 23 to rotate, causing the slider 24 to move within the guide rail 22. The fixing ring 25 on the slider 24 is connected to the U-shaped water pipe 26, the upper spray pipe 27, and the lower spray pipe 28. The spray device moves back and forth in the spray tank 3 as the slider 24 moves, spraying water from top to bottom to rinse the empty tank in the metal mesh frame 21. The wastewater generated during the spraying process flows into the collection tank 6 below through the spray tank 3 for collection. The collection tank 6 can be connected to a sewage treatment system to treat the wastewater before discharge or recycling, in order to meet the requirements of energy conservation and environmental protection. The entire cleaning process is controlled by an external controller. Motor 18 is used to control the lateral movement of the slide 16 in the guide rail 14, which can move the metal mesh frame 21 to different positions as needed. Motor 30 is used to control the back and forth movement of the spray device to ensure full cleaning coverage. The electric telescopic rod 19 is used to control the up and down movement of the guide rail 14 to realize the switching of the metal mesh frame 21 between the soaking tank 2 and the spray tank 3. Through the precise control of the external controller, the cleaning process is automated and efficient.
