Description

Technical Field

[0001] This utility model relates to the field of aluminum can manufacturing technology, specifically to a structure for thoroughly cleaning internal coatings and removing external spray particles. Background Technology

[0002] Aluminum cans used for packaging food and beverages are commonly known as aluminum easy-open cans. The production of aluminum cans involves multiple processes, with the inner coating being a crucial step. The inner coating is typically used to enhance the corrosion resistance and sealing of the can's inner wall. However, after the inner coating is applied, some particles often remain on the can's surface. These particles may be impurities in the coating itself or splatter from the coating process. If these residual particles are not removed promptly, they can cause scratches, dents, and other defects during subsequent processing, thus affecting the product's appearance and performance.

[0003] The patented device for spraying the inner wall of aluminum cans, disclosed in announcement number CN211801894U, involves moving the device to a point of use. The device is supported by feet and secured with pads. Once stable, the top cover is removed via the handle, and paint is added to the storage box. The top cover is then closed, and the interior of the storage box is observed through the viewing window. The aluminum can is placed on a conveyor belt. A motor drives the drive wheel, which in turn drives the driven wheel, causing the connecting rod to rotate, which in turn drives the rotating roller. This moves the conveyor belt, thus moving the aluminum can until it is below a rotating ring. An electric push rod then moves the rotating ring, allowing the nozzle to be inserted into the can. A compression spring presses and pushes the nozzle, causing it to press against the can. Paint from the storage box enters the nozzle through a hose and is sprayed out, thus spraying the inner wall of the aluminum can.

[0004] Although the nozzle of the aforementioned can inner wall spraying device is designed to be inserted into the can for spraying, during the spraying process, due to the high-pressure spraying of the paint or the friction between the nozzle and the inner wall of the can, the paint may still splash out and fall on the outer surface of the can, forming paint particles that affect its surface quality. These paint particles need to be cleaned in time to improve the pass rate of the cans.

[0005] Therefore, it is necessary to invent a structure that thoroughly cleans the internal coating and removes external spray particles to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a structure for thoroughly cleaning internal coatings and removing externally sprayed particles, thereby solving the problems in the aforementioned technologies.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a structure for thoroughly cleaning internal coating particles sprayed externally, comprising a base, a ring conveyor mounted on the top of the base, a blowing mechanism provided on one side of the ring conveyor, the blowing mechanism comprising an outer mounting plate mounted on the surface of the ring conveyor, an air nozzle and a system control box mounted on the surface of the outer mounting plate, a solenoid valve mounted in the middle of the air passage of the air nozzle, the ring conveyor and the solenoid valve being electrically connected to the system control box, a brushing mechanism provided on one side of the ring conveyor, the brushing mechanism comprising a fixed column mounted on the top of the base, a side support plate fixedly connected to the surface of the fixed column, and a cleaning brush provided at the end of the side support plate near the ring conveyor.

[0008] Preferably, the outer mounting plate is fan-shaped, and the number of jet nozzles is set to multiple, with the multiple jet nozzles evenly distributed on the arc-shaped edge of the outer mounting plate.

[0009] Preferably, the number of side support plates is set to multiple, one end of each side support plate is provided with a slot, and one end of the cleaning brush is fixedly connected with a card block, the card block engaging with the slot.

[0010] Preferably, the conveyor belt surface of the annular conveyor is provided with a fixing mechanism, and the number of fixing mechanisms is set to multiple, and the multiple fixing mechanisms are evenly distributed.

[0011] Preferably, the fixing mechanism includes a fixing seat, which is mounted on the surface of the conveyor belt of the annular conveyor.

[0012] Preferably, a DD direct drive motor is installed inside the fixed base, and a disc is provided above the top opening of the fixed base, the disc being connected to the output shaft of the DD direct drive motor.

[0013] Preferably, a vacuum suction cup is mounted on the front of the disk, and a miniature vacuum generator is mounted on the back of the disk. The vacuum suction cup and the miniature vacuum generator are connected through an air passage.

[0014] Preferably, a collection frame is provided on the top of the base, and the air nozzle and cleaning brush are both located above the collection frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By setting up a blowing mechanism and a brushing mechanism, the aluminum can undergo two cleaning processes, blowing and brushing, during the movement of the aluminum can, which effectively removes the coating particles on the surface of the aluminum can, which helps to improve the surface quality of the aluminum can and thus improve the pass rate of the aluminum can.

[0017] 2. The cleaning brush is fixed to the side support plate by a snap-fit ​​mechanism between the clip and the slot, which facilitates maintenance and replacement. When the cleaning brush is worn or needs to be replaced, the replacement can be easily completed by simply removing the clip.

[0018] 3. The fixing mechanism, through the cooperation of vacuum suction cup and micro vacuum generator, can firmly adhere to the bottom of aluminum can products. The DD direct drive motor inside the fixing mechanism can drive the disc to rotate, thereby driving the aluminum can adsorbed by the vacuum suction cup to rotate, which facilitates subsequent blowing and brushing of the aluminum can surface.

[0028] In one aspect of this embodiment, the outer mounting plate 4 is fan-shaped, and the number of air nozzles 5 is set to multiple, which are evenly distributed on the arc-shaped edge of the outer mounting plate 4. The number of side support plates 10 is also multiple, and one end of the side support plate 10 is provided with a slot 12. One end of the cleaning brush 11 is fixedly connected to a locking block 13, which engages with the slot 12. The surface of the conveyor belt of the circular conveyor 2 is provided with a fixing mechanism 14, which is set to multiple and evenly distributed. The fixing mechanism 14 includes a fixing base 1. 5. The fixed base 15 is installed on the surface of the conveyor belt of the circular conveyor 2. The fixed base 15 is equipped with a DD direct drive motor 16. A disc 17 is set above the top opening of the fixed base 15. The disc 17 is connected to the output shaft of the DD direct drive motor 16. A vacuum suction cup 18 is installed on the front of the disc 17. A micro vacuum generator is installed on the back of the disc 17. The vacuum suction cup 18 and the micro vacuum generator are connected through an air passage. A collection frame 19 is set on the top of the base 1. The air nozzle 5 and the cleaning brush 11 are both set above the collection frame 19.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-5 When using this utility model, first place the aluminum cans that need to be cleaned one by one on the vacuum suction cup 18 of the fixing mechanism 14, start the micro vacuum generator in each fixing mechanism 14, the micro vacuum generator performs a vacuuming operation on the vacuum suction cup 18 through the air pipeline, so that the bottom of the aluminum can is tightly adsorbed on the vacuum suction cup 18, ensuring that the aluminum can can be stably transported and rotated in subsequent steps.

[0031] The ring conveyor 2 is started by the system control box 6. The conveyor belt of the ring conveyor 2 begins to move along the predetermined route, driving the multiple fixed mechanisms 14 fixed on it and the aluminum can products on them to move together.

[0032] When the aluminum can moves to the blowing mechanism 3 along with the ring conveyor 2, the system control box 6 will automatically stop the operation of the ring conveyor 2. Then, the system control box 6 will open the solenoid valve 7, allowing high-pressure air to be ejected through the jet nozzle 5. The DD direct drive motor 16 drives the disc 17 to rotate, thereby driving the aluminum can that is attracted by the vacuum suction cup 18 to rotate, so that the high-pressure air can fully cover the surface of the aluminum can. The high-pressure air blows off the paint particles attached to the surface of the aluminum can, and these particles then fall into the collection frame 19.

[0033] After the purging is completed, the system control box 6 restarts the ring conveyor 2 to transport a new batch of aluminum cans to the purging mechanism 3 for cleaning, while the cleaned aluminum cans continue to move with the ring conveyor 2.

[0034] When the aluminum can product moves to the brushing mechanism 8, the surface of the aluminum can is further brushed and cleaned with the help of the cleaning brush 11 to remove residual paint particles from the surface of the aluminum can. The brushed particles also fall into the collection box 19.

[0035] After two cleaning processes, namely blowing and brushing, the surface quality of the aluminum can products is significantly improved, and the paint particles are effectively removed. The cleaned aluminum can products continue to move with the circular conveyor 2 to the next process for further processing or collection.
