The handle 834 is fixed to the conversion joint 835 by a set screw for easy operation.

[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings, and its complete working process will be explained. The fully automatic high-sealing aluminum-plastic blister packaging machine with a spray cleaning system in this embodiment mainly includes two core processes: a normal sealing packaging process and an automatic spray cleaning process.

[0039] I. Normal Sealed Packaging Workflow

[0040] When pharmaceutical packaging operations are required, the equipment first executes the normal closed-loop packaging process: the outdoor air conditioning unit 2 and fan 4 are started, and clean air, after temperature and humidity control, is sent into the main body 1 of the high-density aluminum-plastic blister packaging machine through the air inlet duct 5, creating a positive pressure environment. The air inside the equipment, as well as any trace dust that may be generated, is extracted through the exhaust duct 6, undergoes high-efficiency filtration through the outdoor filter 3, and is then discharged into the atmosphere or recirculated. This ventilation system ensures that the inside of the equipment is always under clean negative pressure or controllable pressure, effectively preventing the leakage of internal contaminants.

[0041] Materials (such as tablets or capsules) enter the unloading station through AB valve interface 7 (the alternating opening and closing design of the AB valve ensures complete isolation of the material from the external environment during transfer). The material falls into hopper 10, and its unloading process is buffered and sealed by a cloth bag 9 installed on AB valve interface 7 to further prevent dust from flying. Subsequently, the material completes fully automated packaging processes such as blister forming, filling, heat sealing, and die-cutting at other stations of the equipment.

[0042] II. Automatic Spray Cleaning Workflow

[0043] When packaging is completed or a changeover and cleaning process is required, the equipment initiates an automatic spray cleaning process. This process requires no personnel intervention. After packaging operations cease, the operator selects "Spray Cleaning Mode" on the equipment control panel and starts the program. The control system first confirms that all valves are closed. It then activates the pumped water source connected to port A of the four-way connector 820, providing purified water with a certain pressure and flow rate. The control system first opens diaphragm valve 1 817 while keeping diaphragm valve 2 818 and diaphragm valve 3 819 closed. Purified water enters the four-way connector 820 from port A, flows out through port B and the already opened diaphragm valve 1 817. The purified water is then distributed to three-way connectors 1 811, 2 812, 3 813, and 4 814, and is delivered through transparent silicone braided water pipes to the corresponding four spray connector branch pipes 82. Purified water flows through branch pipe seat 821, passes through a custom-designed stainless steel bend 822, and is finally sprayed out in atomized form from spray head 823, thus performing a preliminary and comprehensive pre-rinse to wash away most of the residue. After the wide-area rinsing is completed, the operator can individually or in combination open diaphragm valve two 818 and diaphragm valve three 819 through the control system. When diaphragm valve two 818 is open, purified water flows out from port D of four-way connector 820 and through straight connector one 815 to one of the self-made spring tube spray guns 83. When diaphragm valve three 819 is open, purified water flows out from port C and through straight connector two 816 to the other self-made spring tube spray gun 83. At this time, the operator can hold the handle 834 of any homemade spring tube spray gun 83 for cleaning. Since the spring tube 833 is made of PFA material, it has excellent flexibility and corrosion resistance. The operator can bend and stretch the spray gun at will, and accurately aim its nozzle at any stubborn stains and dead corners for close-range, high-pressure point spraying and brushing, ensuring that there are no blind spots in cleaning.

[0044] After the spray cleaning process is completed, all diaphragm valves are closed and the water pumps stop. The ventilation system can continue to operate or start the drying mode to introduce clean, dry air to purge and dry the interior of the equipment, preventing the growth of microorganisms.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
