Description

Technical Field

[0001] This invention relates to the field of pharmaceutical filling equipment technology, specifically to an automatic cleaning and filling equipment for Five Flavors Sweet Dew medicinal bath liquid. Background Technology

[0002] Five-Flavor Sweet Dew Medicated Bath Liquid originates from an ancient Tibetan medicine formula passed down for thousands of years, a treasure of Tibetan health culture. Its formula is based on the Tibetan medical theory of "balancing the three factors," carefully selecting five authentic plateau herbs: juniper leaves, yellow rhododendron, water juniper branches, ephedra, and clump-forming chrysanthemum. In the pharmaceutical production process of Five-Flavor Sweet Dew Medicated Bath Liquid, the cleaning and filling of the medicine bottles are crucial steps in ensuring the quality of the medicine. Automatic bottle cleaning typically involves multiple stages: first, a pre-rinse removes surface dust and residual debris, usually using purified water for initial spraying; then, a deep cleaning stage uses ultrasonic vibration or high-pressure rotary spraying to remove stubborn stains from the bottle's inner walls (such as the bottle neck threads and the bottom arc); finally, a final rinse with water and hot air drying ensure the cleanliness of the bottle meets requirements. The medicine bottle filling process must be carried out in a clean environment: after the cleaned and dried medicine bottles are positioned by the conveying mechanism, the filling head fills the liquid medicine quantitatively according to the set dosage. Some equipment will also perform online detection of the filling volume at the same time to reject unqualified products to ensure dosage accuracy.

[0003] However, in existing technologies, the cleaning and filling processes mostly rely on separate equipment. After cleaning, the bottles need to be transferred to the filling machine manually or via an intermediate conveyor. This process not only interrupts production continuity and reduces the efficiency of single-batch processing, but also increases the risk of secondary contamination because the bottles are exposed to a non-absolutely clean environment during the transfer. At the same time, the parameter adjustments for the separate equipment need to be performed separately, and the connection accuracy between the two devices needs to be calibrated additionally when changing models, further extending the production preparation time and making it difficult to meet the high-efficiency and sterile production requirements of the modern pharmaceutical industry. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an automatic cleaning and filling equipment for Five Flavors Sweet Dew Medicinal Bath Liquid, so as to at least partially solve the problems mentioned in the background art.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The automatic cleaning and filling equipment for Five-Flavor Sweet Dew Medicated Bath Liquid according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figures 2-4As shown in the figure, the automatic cleaning and filling equipment for Wuwei Ganlu medicinal bath liquid provided in this embodiment of the invention includes a feeding mechanism 2 and a composite cleaning and filling mechanism 3. The feeding mechanism 2 is located below the composite cleaning and filling mechanism 3 and includes two vertical and parallel feeding conveyor belts 23. The outer surface of the feeding conveyor belts 23 is provided with a conveying clamp 24.

[0023] The composite cleaning and filling mechanism 3 includes an injection cylinder assembly 31 and a bottle mouth clamping assembly 33. The injection cylinder assembly 31 is located above the feeding conveyor belt 23 and includes an injection cylinder 313 and a retractable injection rod 316 located at the bottom of the injection cylinder 313. The bottle mouth clamping assembly 33 is located at the bottom of the injection cylinder 313 and is provided with a filling nozzle 337. The filling nozzle 337 is connected to the bottom of the bottle mouth clamp 332 through a filling tube 338.

[0024] Specifically, when using the automatic cleaning and filling equipment of this application, the medicine bottles 4 are first placed one by one into the transmission fixture 24, and the medicine bottles 4 are continuously moved to the composite cleaning and filling mechanism 3 by the feeding conveyor belt 23. When the mouth of the medicine bottle 4 reaches below the mouth clamping component 33, the mouth clamping component 33 clamps the mouth of the medicine bottle 4.

[0025] Then, cleaning fluid is pre-injected into the syringe 313. The cleaning fluid gradually cleans the inner wall of the vial 4 from top to bottom through the retractable injection rod 316. After cleaning, the cleaning fluid in the vial 4 is discharged. After cleaning, the vial 4 is directly filled through the filling nozzle 337. During the cleaning and filling process, the clamping component will not leave the mouth of the vial 4. The cleaning and filling are completed in one go, ensuring the sealing and accuracy of the filling process and improving production efficiency.

[0026] In one embodiment of the present invention, such as Figures 4-9 As shown, the top of the syringe 313 is equipped with a liquid injection valve 311 and a gas injection valve 312. A fluid chamber 314 is formed inside the syringe 313, and a piston 315 is installed inside the fluid chamber 314. The injection rod 316 passes through the piston 315 and is fixedly connected to it. The top of the injection rod 316 is connected to the fluid chamber 314 above the piston 315 via a pressure valve 319, ensuring that no liquid flows out of the injection rod 316 during the cleaning fluid injection process. A waste discharge nozzle 331 is also provided on the bottle mouth clamping assembly 33. A liquid guide tube 318 is provided at the bottom of the syringe 313, communicating with the fluid chamber 314 below the piston 315. A reset liquid pump 317 is provided at the other end of the liquid guide tube 318.

[0027] The syringe assembly 31 is provided with a flipping assembly 32 on both sides, including a flipping table 322 and a flipping motor 321. The flipping table 322 is located outside the syringe 313, and flipping shafts 323 are provided on both sides of the flipping table 322. The output shaft of the flipping motor 321 is connected to the flipping shafts 323.

[0028] Specifically, in combination Figure 8 and Figure 9 As shown, when cleaning the medicine bottle 4, cleaning fluid is first injected into the upper fluid chamber 314 of the piston 315 through the liquid injection valve 311. At the same time, the reset fluid pump 317 draws the reset fluid out of the lower fluid chamber 314 of the piston 315 through the liquid guide tube 318. The piston 315 and the injection rod 316 move downward at the same time. When the upper fluid chamber 314 of the piston 315 is filled with cleaning fluid, the liquid injection valve 311 is closed. At this time, the bottom of the injection rod 316 reaches the bottom of the medicine bottle 4.

[0029] Subsequently, the reset fluid pump 317 pumps the reset fluid back into the fluid chamber 314 below the piston 315, driving the piston 315 to move upward. During the upward movement of the piston 315, the cleaning fluid injected into the fluid chamber 314 above the piston 315 is forced into the injection rod 316 from the pressure valve 319. The injection rod 316 injects the pressurized cleaning fluid into the inner wall of the medicine bottle 4, and the injection rod 316 will continuously move upward along the bottom of the medicine bottle 4 to clean the inner wall of the medicine bottle 4, so that the inner wall of the medicine bottle 4 is cleaned more thoroughly.

[0030] like Figure 9 As shown, the flipping motor 321 then drives the flipping table 322 to flip 180 degrees, which in turn drives the syringe assembly 31 and the medicine bottle 4 to flip together. After flipping, drying gas is injected into the fluid chamber 314 on the upper side of the piston 315 through the gas injection valve 312. The drying gas blows away the cleaning liquid remaining on the inner wall of the medicine bottle 4 in the same way as the cleaning liquid injection described above. The gas in the medicine bottle 4 transfers the cleaning liquid in the medicine bottle 4 through the waste discharge pipe 333 in the bottle mouth holder 332 to the waste discharge nozzle 331, and finally discharges the cleaning liquid.

[0031] Furthermore, since the medicine is rotated 180 degrees at this time, the syringe 316 blows the inner wall of the medicine bottle 4 from top to bottom, causing the residual cleaning solution on the inner wall of the medicine bottle 4 to be gradually blown downward by gravity and discharged along the waste discharge nozzle 331, making the inner wall of the medicine bottle 4 cleaner.

[0032] In one embodiment of the present invention, such as Figure 4 and Figure 5As shown, an injection assembly 34 is provided at the bottom of the injection rod 316, including an injection head 342. The injection head 342 and the injection rod 316 are rotatably connected by a rotating seat 341. A side wall nozzle 343 is provided on the side wall of the injection head 342, and a bottom nozzle 345 is provided at the bottom of the injection head 342. Both the side wall nozzle 343 and the bottom nozzle 345 are connected to the injection rod 316. A turbine blade 344 is provided inside the injection head 342.

[0033] Specifically, in order to ensure that the cleaning solution fully and evenly contacts the inner wall of the medicine bottle 4, the fluid in the injection rod 316 flushes the side wall of the medicine bottle 4 through the side wall nozzle 343, and the fluid flushes the bottom of the medicine bottle 4 through the bottom nozzle 345. During the flushing process, the fluid drives the turbine blades 344 inside the injection head 342 to rotate, thereby driving the injection head 342 to rotate and flush the inner wall of the medicine bottle 4, so that the cleaning solution fully and evenly contacts the inner wall of the medicine bottle 4.

[0034] In one embodiment of the present invention, such as Figure 4 , Figure 8 and Figure 9 As shown, the bottle mouth clamping assembly 33 includes a bottle mouth clamp 332, an air bladder 334, and an air bladder pump 336. The bottle mouth clamp 332 is located at the bottom of the syringe 313, and a clamping port 335 is opened at the bottom of the bottle mouth clamp 332. The air bladder 334 has an annular structure and is located on the inner wall of the clamping port 335. The air bladder 334 and the air bladder pump 336 are connected through a pipeline.

[0035] A push rod 25 is provided on the base plate 26. A push rod 251 is provided on the output shaft of the push rod 25. The push rod 251 passes through the base plate 26. A support 252 is provided on the top of the push rod 251. The support 252 corresponds vertically to the injection rod 316. A support hiding groove 253 is also provided on the base plate 26.

[0036] Specifically, when the vial 4 reaches below the injection rod 316, the push rod 25 is pushed out, causing the push rod 251 and the support 252 to move upward. The support 252 pushes the vial 4 upward and sends it to the bottom of the vial mouth holder 332. Then, when the mouth of the vial 4 enters the clamping port 335 at the bottom of the vial mouth holder 332, the airbag and air pump 336 transmit gas to the airbag 334. The airbag 334 wraps and locks the outside of the vial mouth in the clamping port 335, isolating the vial mouth from the external environment and ensuring the sealing during the cleaning and filling process.

[0037] After the medicine bottle 4 is cleaned, the flipping component 32 drives the medicine bottle 4 to flip 180° again, and the medicine bottle 4 falls back onto the support 252. Then, the airbag and air pump 336 retract the gas in the airbag 334, and the mouth of the medicine bottle 4 leaves the bottle mouth holder 332. Finally, the push rod 25 descends and drives the medicine bottle 4 to fall back onto the feeding conveyor belt 23.

[0038] In one embodiment of the present invention, such as Figure 6 and Figure 7 As shown, a height adjustment assembly 35 is also provided on one side of the flip shaft 323, including a support arm 351 and a telescopic base 352. The support arm 351 is rotatably connected to the flip shaft 323, the flip motor 321 is fixedly mounted on the support arm 351, and the telescopic base 352 is located at the bottom of the support arm 351. The working height of the bottle mouth clamping assembly 33 is adjusted by the telescopic base 352, which is used to adjust the clamping position of the bottle mouth according to the different heights of the medicine bottles 4.

[0039] In one embodiment of the present invention, such as Figure 2 As shown, the clamping surface of the transfer clamp 24 is provided with a V-shaped clamping groove. The clamping surface of the transfer clamp 24 is made of elastic silicone material to reduce clamping damage. The outside of the feeding conveyor belt 23 is provided with a transfer bracket 21. The transfer drive motor 22 that drives the feeding conveyor belt 23 to rotate is provided on the transfer bracket 21. The bottom of the transfer bracket 21 is provided with a transfer base plate 26.

[0040] Specifically, the V-shaped clamping groove of a conveyor 24 can automatically clamp one medicine bottle 4 and expel other medicine bottles 4. The V-shaped clamping groove can also clamp and center the medicine bottles 4, so that the medicine bottles 4 are neatly arranged in the feeding conveyor belt 23.

[0041] In one embodiment of the present invention, such as Figure 2 As shown, the feeding conveyor belt 23 is provided with inlet and outlet components 1 at both ends, including a feed plate 11 and an outlet plate 14. The bottom of the feed plate 11 and the outlet plate 14 is provided with a bracket 13. The feed plate 11 is provided at the feed end of the feeding conveyor belt 23, and the outlet plate 14 is provided at the discharge end of the feeding conveyor belt 23. The feed plate 11 and the outlet plate 14 are also provided with a guard plate 12 for limiting the feeding of the medicine bottle 4 during the feeding and discharging process.

[0042] To clearly illustrate the above embodiments, refer to Figures 1-9 The working principle of the automatic cleaning and filling equipment for the Five Flavors Sweet Dew Medicinal Bath Liquid of the present invention is as follows: When the automatic cleaning and filling equipment of this application is used, the medicine bottles 4 are first placed one by one on the feeding plate 11 and enter the feeding conveyor belt 23. The medicine bottles 4 are continuously entered into the transmission clamps 24 of each V-shaped groove structure through the feeding conveyor belt 23. Then the medicine bottles 4 are continuously moved to the composite cleaning and filling mechanism 3.

[0043] When the mouth of the medicine bottle 4 reaches below the bottle mouth clamping assembly 33, the push rod 25 pushes the push rod 251 and the support 252 upward. The support 252 pushes the medicine bottle 4 upward and sends it to the bottom of the bottle mouth clamp 332. Then, when the mouth of the medicine bottle 4 enters the clamping port 335 at the bottom of the bottle mouth clamp 332, the airbag and air pump 336 transmit gas to the airbag 334. The airbag 334 wraps and locks the outside of the bottle mouth in the clamping port 335.

[0044] When cleaning the vial 4, cleaning fluid is injected into the fluid chamber 314 above the piston 315 through the liquid injection valve 311. At the same time, the reset fluid pump 317 draws the reset fluid out of the fluid chamber 314 below the piston 315 through the liquid guide tube 318. The piston 315 and the injection rod 316 move downwards at the same time. When the fluid chamber 314 above the piston 315 is filled with cleaning fluid, the liquid injection valve 311 is closed. At this time, the bottom of the injection rod 316 reaches the bottom of the vial 4.

[0045] like Figure 8 As shown, the reset fluid pump 317 then pumps the reset fluid back into the fluid chamber 314 below the piston 315, driving the piston 315 to move upward. During the upward movement of the piston 315, the cleaning fluid injected into the fluid chamber 314 above the piston 315 is forced into the injection rod 316 from the pressure valve 319. The injection rod 316 injects the pressurized cleaning fluid into the inner wall of the medicine bottle 4, and the injection rod 316 will continuously move upward along the bottom of the medicine bottle 4 to clean the inner wall of the medicine bottle 4, so that the inner wall of the medicine bottle 4 is cleaned more thoroughly.

[0046] like Figure 9 As shown, the flipping motor 321 then drives the flipping table 322 to flip 180 degrees, which in turn drives the syringe assembly 31 and the medicine bottle 4 to flip together. After flipping, drying gas is injected into the fluid chamber 314 on the upper side of the piston 315 through the gas injection valve 312. The drying gas blows away the cleaning liquid remaining on the inner wall of the medicine bottle 4 in the same way as the cleaning liquid injection described above. The gas in the medicine bottle 4 transfers the cleaning liquid in the medicine bottle 4 through the waste discharge pipe 333 in the bottle mouth holder 332 to the waste discharge nozzle 331, and finally discharges the cleaning liquid, making the inside of the medicine bottle 4 drier.

[0047] After the medicine bottle 4 is cleaned, the flipping component 32 flips the medicine bottle 4 180° again, and the medicine bottle 4 falls back onto the support 252. Then, the medicine bottle 4 is directly filled through the filling nozzle 337. The gas in the medicine bottle 4 is discharged from the waste discharge nozzle 331. After the filling is completed, the airbag and air pump 336 retracts the gas in the airbag 334, and the mouth of the medicine bottle 4 leaves the bottle mouth holder 332. Finally, the push rod 25 lowers and drives the medicine bottle 4 back onto the feeding conveyor belt 23, completing the cleaning and filling process.

[0048] In summary, the automatic cleaning and filling equipment for Wuwei Ganlu medicinal bath liquid in this embodiment of the invention clamps the mouth of the medicine bottle with a bottle mouth clamping component, injects cleaning liquid into the syringe, and the cleaning liquid gradually cleans the inner wall of the medicine bottle from top to bottom through a retractable injection rod. After the medicine bottle is cleaned, it is directly filled into the medicine bottle through the filling nozzle. During the cleaning and filling process, the clamping component does not leave the mouth of the medicine bottle, and the cleaning and filling are completed in one go, ensuring the sealing and accuracy of the filling process and improving production efficiency.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
