[0002] In the use of fluid filling equipment in pharmaceuticals, food, and other industries, the cleanliness of the filling nozzle, as the core component for material output, directly affects product quality.
[0003] Before filling production, to ensure the hygiene and safety of the filled products, the inner walls of filling components such as filling valves and infusion pipelines need to be cleaned. When cleaning the filling valve, the outlet of the filling valve needs to be sealed with a dummy cup.
[0004] Currently, most filling nozzle cleaning methods on the market rely on manual disassembly and cleaning or simple spray cleaning. These methods have problems such as cumbersome operation procedures, incomplete cleaning, low automation, and easy secondary pollution, making it difficult to meet the high-efficiency and clean production requirements of modern production lines. Summary of the Invention

To achieve the above objective, this invention provides the following technical solution: a rotary cylinder, including a reversing valve, an air inlet pipe provided on one side of the reversing valve, an output port on one side of the reversing valve fixedly connected to one end of the air inlet pipe, a bottom of the reversing valve fixedly connected to the top of a high-pressure cylinder body, an inner wall of the high-pressure cylinder body fixedly connected to the other end of the air inlet pipe, an inner wall of the high-pressure cylinder body slidably connected to the outer wall of a piston shaft, a bottom of the high-pressure cylinder body fixedly connected to the top of a guide assembly by bolts, an inner wall of the piston shaft rotatably connected to the outer wall of a rotating assembly, and an inner wall of the rotating assembly movably inserted into the outer wall of a filling assembly.
[0006] Preferably, the reversing valve is an electromagnetic reversing valve, and the reversing valve can control the high-pressure gas input from the intake pipe to be introduced into the high-pressure cylinder body through the air exchange pipe or directly input into the high-pressure cylinder body. The reversing valve can control the high-pressure gas to be output directly from the intake pipe through the reversing valve or output through the air exchange pipe. After the high-pressure gas input from the external air pump enters the reversing valve through the intake pipe, it is controlled by the reversing valve to enter the high-pressure cylinder body through the air exchange pipe or directly into the high-pressure cylinder body.
[0007] Preferably, the guide assembly includes a fixed platform, a guide fixing seat, and a guide groove. The inner wall of the fixed platform is fixedly connected to the bottom of the high-pressure cylinder by bolts, and the bottom of the fixed platform is fixedly connected to the top of the guide fixing seat. The guide fixing seat has a guide groove inside, and the inner wall of the guide groove is slidably connected to the outer wall of the rotating assembly.

The outer wall of the connecting pin is movably inserted into the outer wall of the filling assembly. The piston shaft is connected to the rotating cam through the connecting rod. When the rotating cam slides in the guide fixed seat, the rotating cam drives the fixed pin to slide in the guide groove. The fixed pin first moves vertically downward by 5 mm in the guide groove, and then moves obliquely by 48 degrees along the inclined groove, for a total movement of 10 mm.

Conversely, the filling nozzle first moves vertically downward with the connecting platform to disengage from the dispensing nozzle, and then rotates 48 degrees with the connecting block. The connecting block drives the connecting platform to move to a designated area, thereby completing the automatic cleaning function.
[0013] Preferably, the bottom of the connecting block is provided with a positioning hole, and the inner wall of the positioning hole is movably inserted into the outer wall of the connecting pin located inside the connection port.

When the connecting block rotates coaxially, it will drive the connecting platform to rotate. When the connecting platform rotates, it will drive the cleaning dummy cup and the filling nozzle to rotate. The connecting platform first rotates forty-eight degrees to align the filling nozzle with the dispensing nozzle, and then moves vertically upward to block the dispensing nozzle, thereby achieving the purpose of automatic cleaning. Conversely, the filling nozzle first follows the connecting platform to move vertically downward to detach from the dispensing nozzle, and then follows the connecting block to rotate forty-eight degrees. The connecting block drives the connecting platform to move to the designated area, thereby completing the automatic cleaning function.
[0016] In this invention, high-pressure gas input from an external air pump enters the reversing valve through the intake pipe. The reversing valve controls the gas to enter the high-pressure cylinder from the intake pipe or directly into the high-pressure cylinder. The high-pressure gas directly enters the high-pressure cylinder through the reversing valve, and the gas can push the piston shaft to extend from the high-pressure cylinder. The gas input from the air pump is controlled by an electromagnetic reversing valve, thereby controlling the extension or retraction of the piston shaft, thus achieving automated control.

[0033] In this embodiment, as Figures 1 to 7As shown, the filling assembly 8 includes a connecting block 801, a connecting platform 802, a filling nozzle 803, and a cleaning dummy cup 804.

[0035] The method of use and advantages of this invention: The working process of this rotary cylinder is as follows:
[0036] like Figures 1 to 7 As shown, the high-pressure gas input by the external air pump enters the reversing valve 1 through the air inlet pipe 2, and then enters the high-pressure cylinder 4 through the air exchange pipe 3 or directly into the high-pressure cylinder 4 under the control of the reversing valve 1.
[0037] High-pressure gas enters the high-pressure cylinder 4 directly through the reversing valve 1. The gas can push the piston shaft 5 to extend out of the high-pressure cylinder 4. The piston shaft 5 is connected to the rotary cam 702 through the connecting rod 701. When the rotary cam 702 slides in the guide fixed seat 602, the rotary cam 702 drives the fixed pin 703 to slide in the guide groove 603. The fixed pin 703 first moves vertically downward by 5 mm in the guide groove 603, and then moves obliquely along the inclined groove by 48 degrees, for a total movement of 10 mm.
[0038] High-pressure gas enters the high-pressure cylinder 4 through the air exchange valve 1 and the air exchange pipe 3. When the piston shaft 5 retracts in the high-pressure cylinder 4, it first rotates 48 degrees in the opposite direction, and then moves vertically upward by 5 millimeters, for a total movement of 10 millimeters.
[0039] When the connecting platform 704 rotates, it can directly drive the connecting block 801 to rotate coaxially through the connecting platform 704 and the connecting pin 705. When the connecting block 801 rotates coaxially, it will drive the connecting platform 802 to rotate. When the connecting platform 802 rotates, it will drive the cleaning dummy cup 804 and the filling nozzle 803 to rotate. The connecting platform 802 first rotates forty-eight degrees to align the filling nozzle 803 with the dispensing nozzle, and then moves vertically upward to block the dispensing nozzle, thus achieving the purpose of automatic cleaning. Conversely, the filling nozzle 803 first moves vertically downward with the connecting platform 802 to disengage from the dispensing nozzle, and then rotates forty-eight degrees with the connecting block 801. The connecting block 801 drives the connecting platform 802 to move to the designated area, thereby completing the automatic cleaning function.
