[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an aluminum can internal coating machine, including a processing table 1 for coating the inside of the aluminum can. A three-jaw chuck 8 is provided on the table via a rotating assembly. The jaws of the three-jaw chuck 8 are provided with clamping components to facilitate clamping and fixing the outer wall of the aluminum can. The three-jaw chuck 8 can be manual or pneumatic (selected according to actual conditions, to facilitate clamping the aluminum can with the clamping components, which is a relatively mature technology and will not be described in detail here). The rotating assembly includes a motor 7 located at the bottom of the processing table 1. The output end of the motor 7 passes through the processing table 1 and extends upwards, and a rotating plate 5 is fixedly installed on it via a coupling. The rotating plate 5 is fixedly connected to the bottom of the three-jaw chuck 8 (it can be fixedly connected by screws, etc.). Support legs (not shown in the figure) can be welded to the four corners of the bottom of the processing table 1 to ensure the overall stability and firmness. Clamping blocks 9 of the clamping components can be fixedly installed on the jaws via screws. The inner arc surface of the clamping blocks 9 is bonded with rubber pads 10 to avoid hard contact with the aluminum can.

[0023] Please see Figures 1-5To ensure effective coating of the aluminum can's interior and facilitate position adjustment for pretreatment and coating operations, a linear guide rail device 2 with a moving mechanism is installed on the processing table 1. A guide rail slider 4 (driven by a linear motor for reciprocating movement, or adjusted via a reciprocating screw, a mature technology not described here) slides on the linear guide rail device 2. The guide rail slider 4 is fixedly connected to the lifting plate 6 via an electric push rod 3, allowing for easy lifting and lowering. The lifting plate 6 moves up and down as a whole. To ensure stability, a counterweight plate 21 is welded to the end of the lifting plate 6 near the electric push rod 3. To facilitate coating operations, a material storage box 11 for the coating mechanism is installed on the lifting plate 6 (used to store the paint to be coated; a feeding pipe is installed at the top of the material storage box 11 for easy feeding). The side wall of the material storage box 11 is connected to a discharge pipe 13 via a conveying pump (not shown in the figure). The discharge pipe 13 passes through the lifting plate 6 and extends downwards to connect to a material storage roller 14. The peripheral side of the material storage roller 14 (such as...) Figure 4 As shown, the material storage roller 14 is provided with equidistant holes, and the coating roller 15 is sleeved on the outside of the material storage roller 14, which can easily wet the coating roller 15 with the coating material. Then, the motor 7 drives the aluminum can on the rotating plate 5 to rotate, and at the same time, the electric push rod 3 extends and retracts, so as to fully and evenly coat the inside of the aluminum can.

[0024] Please see Figures 1-5 To facilitate cleaning and collection of the inner wall of the aluminum can and ensure cleanliness, a collection box 12 is installed on the lifting plate 6. The collection box 12 (which is equipped with an exhaust fan and other components, similar to a vacuum cleaner, a mature technology that will not be elaborated here) has a collection pipe 17 connected to its side wall. The collection pipe 17 passes through the lifting plate 6 and extends to the bottom to connect to an annular pipe 16. Collection ports 18 are evenly spaced at the bottom of the annular pipe 16 to facilitate the collection of debris and floating dust and other impurities inside the aluminum can. To ensure the collection effect, maintain cleanliness, and not affect subsequent coating, a connecting plate 19 is attached to the bottom of the collection pipe 17. A wiping cotton 20 (with a U-shaped cross-section) is attached to the outside of the connecting plate 19 to facilitate wiping and cleaning the inside of the aluminum can.

[0025] Working Principle: In use, the aluminum can to be coated is placed on the three-jaw chuck 8. The three-jaw chuck 8 moves its three jaws closer together, allowing the clamping blocks 9 and rubber pads 10 to clamp and fix the outer wall of the aluminum can. The linear guide rail device 2 moves the guide rail slider 4, moving the annular tube 16 on the lifting plate 6 directly above the aluminum can. Then, the electric push rod 3 retracts, lowering the lifting plate 6. At this time, the wiping cotton 20 on the outside of the connecting plate 19 enters the aluminum can. After reaching the bottom, the motor 7 rotates the rotating plate 5 and the entire aluminum can, allowing the wiping cotton 20 to wipe the inside of the aluminum can. The exhaust fan inside the collection box 12 operates, collecting debris and other contaminants through the collection port 18 under the annular pipe 16. The debris then enters the collection box 12 through the collection pipe 17. At this time, the electric push rod 3 slowly moves upward, thoroughly cleaning the inside of the aluminum can. After cleaning, the linear guide rail device 2 operates, moving the guide rail slider 4 as a whole, which moves the coating roller 15 directly above the aluminum can. Then, the above steps (cleaning the inside of the aluminum can) are completed. The coating is then conveyed to the storage roller 14 through the discharge pipe 13. Together with the coating roller 15, the inside of the aluminum can is coated. At the same time, the electric push rod 3 slowly extends, moving upward as a whole, thoroughly coating the inside and completing the coating process of the aluminum can.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
