[0002] In many industries, especially in the production of food and beverages, pharmaceuticals, cosmetics, and chemicals, container cleaning is a crucial part of the production process. Ensuring the cleanliness and sterilization of the bottle's interior is essential for maintaining product quality, meeting hygiene standards, and protecting consumer safety. Currently, bottles are often used directly for filling after production, neglecting to clean the interior.

[0003] The existing bottle cleaning machine works by placing the bottles upside down on a rack in the cleaning chamber, rinsing the inside of the bottles with pressurized water, and finally drying the inside of the bottles with air. However, existing bottle cleaning machines have low cleaning efficiency and cannot be automated into production lines because the bottles need to be removed from the cleaning chamber after drying and then transferred to the next process.

[0004] Traditional manual cleaning methods are not only time-consuming and labor-intensive, but also difficult to achieve consistent cleaning results and high standards of hygiene. Utility Model Content

[0066] In the optional scheme of this embodiment, a preferred embodiment is that the first guide plate 24 is fixedly connected to the main support plate 21 through a support plate, and the support plate is provided with a vertical guide groove, with the support plate corresponding to the cleaning support column 25 one-to-one; the cleaning support column 25 is equipped with a second roller 27 that rolls in cooperation with the vertical guide groove on the corresponding support plate; the sliding cooperation between the cleaning support column 25 and the first guide plate 24 is the first guiding function, the rolling cooperation between the second roller 27 and the vertical guide groove bracket 1 is the second guiding function, and the sliding cooperation between the guide column and the second guide plate 23 is the third guiding function. Under the triple action of the first, second and third guiding functions, the cleaning module can be stably raised and lowered, ensuring the stability of the cleaning module's operation.

[0067] The specific working process of the airflow cleaning machine for pharmaceutical bottles in this embodiment is as follows:

[0068] Taking the cleaning process of a bottle as an example, the bottle to be cleaned is placed into the bottle conveyor belt. Under the action of the conveyor belt and the rotation of the bottle screw 2, the bottle to be cleaned moves towards the discharge end of the conveyor belt. It is worth noting that during this process, the bottle to be cleaned is engaged by the threaded groove on the bottle screw 2 and driven to move forward along the conveyor belt. The pitch of the screw on the bottle screw 2 can control the distance between two adjacent bottles on the conveyor belt. When the bottle to be cleaned is conveyed to the discharge end of the conveyor belt, a first slot on the rotary table 3 also rotates to the discharge end of the conveyor belt, and the first slot moves towards the bottle at the discharge end, so that the bottle to be cleaned is engaged in the first slot. Then the rotary table 3 drives the bottle to rotate. When the bottle to be cleaned rotates with the rotary table 3 to the connection point with the cleaning rotary table 22, it is engaged from the first slot into the second slot.

[0069] Then, driven by the cleaning shaft 20, the first roller 26 in the cleaning module, which is positioned directly above the second slot of the bottle to be cleaned, rolls from the rising area 41 on the positioning sleeve 19 into the falling area 42, causing the overall height of the cleaning module to decrease. This allows the docking block 31 to align with the bottle opening in the second slot. During docking, the spring 33 ensures that the mating interface 37 at the bottom of the docking block 31 fits tightly against the bottle opening, guaranteeing a seal between the mating interface 37 at the bottom of the docking block 31 and the bottle opening. The air-blowing needle 35 then extends into the bottle, blowing compressed air into the internal space of the bottle. Foreign objects (such as dust and debris) in the bottle are blown out of the bottle by compressed air and enter the dust collection tank 5 through the cavity in the docking block 31, the dust outlet 36, and the dust inlet 38. Finally, they are sucked away by the negative pressure device through the dust collection sleeve 40. The negative pressure device is a vacuum cleaner, and the dust is finally collected in the negative pressure device. Before the bottle body rotates with the cleaning turntable 22 to the point of connection with the rotating turntable 6, the first roller 26 in the cleaning module directly above the bottle body will roll from the landing area 42 on the positioning sleeve 19 into the lifting area 41, so that the overall height of the cleaning module rises, thereby causing the docking block 31 to separate from the bottle mouth of the bottle body on the second slot, and the blowing needle 35 also leaves the bottle body.

[0070] Then, as the bottle rotates with the cleaning turntable 22 to the point where it connects with the rotating turntable 6, the bottle is inserted from the second slot into the third slot. When the bottle rotates with the rotating turntable 6 to the feed end of the bottle conveyor belt, the bottle enters the bottle conveyor belt from the third slot under the action of the bottle discharge screw 8, and is then discharged under the action of the bottle conveyor belt and the bottle discharge screw 8.

[0071] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
