Description

Technical Field

[0001] This invention belongs to the field of aerosol filling technology, specifically a multi-functional filling machine for aerosol production. Background Technology

[0002] In the large-scale production of aerosols, the filling machine is the core equipment, and its filling accuracy directly determines the product quality and production cost. At present, in the mainstream nasal spray filling and labeling production lines in the industry, the filling machine mostly adopts a structure of ordinary motor combined with chain drive or multi-stage gear drive, which completes the filling operation by driving the relative movement of the filling needle and the conveying tank.

[0003] Existing equipment often uses fixed brackets or simple slide rail structures for filling syringes. Adjustment requires disassembling parts and recalibrating, which is cumbersome and makes it difficult to guarantee accuracy. At the same time, during the production process, the syringe position is prone to slight displacement due to factors such as changes in drug viscosity and equipment vibration, causing the liquid to overflow to the outside of the bottle or drip onto the conveyor track, resulting in a large waste of drug raw materials, increased production losses, pollution of the production environment, and increased workload and cost of subsequent cleaning operations. Therefore, a multi-functional filling machine for spray production has been designed. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-functional filling machine for spray production, so as to solve the problem of low efficiency mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional filling machine for spray production, comprising a filling table, a fixed frame fixedly connected to the top of the filling table, a limiting frame fixedly connected to the top of the fixed frame, a conveying module rotatably connected to the inner wall of the limiting frame, a guide frame fixedly connected to the top of the fixed frame, a lifting plate slidably connected to the outer wall of the guide frame, a toothed plate slidably connected to the inner wall of the lifting plate, a movable groove provided at one end of the lifting plate near the toothed plate, a gear rotatably connected to the inner wall of the movable groove, the gear meshing with the toothed plate, a clamping plate hinged to the outer wall of the toothed plate, a clamping block slidably connected to the inner wall of the clamping plate, a conveying tank sleeved between the clamping block and the toothed plate, guide rails symmetrically fixedly connected to the front end of the fixed frame, a sliding frame slidably connected to the top of the guide rails, a cleaning frame slidably connected to the top of the sliding frame, and a top cover device fixedly provided on the top of the fixed frame.

During the cleaning process, the water supply pipe can be directly connected to a water pump, and the wastewater after cleaning is quickly discharged through a drain pipe. This results in a simple and efficient cleaning operation, extending the service life and ensuring hygiene and safety.

[0018] 3. Compared with traditional devices, this invention is equipped with clamping blocks and adjusting bolts. The operator can precisely push and pull the clamping blocks by rotating the adjusting bolts corresponding to the filling needles, thereby achieving personalized adjustment of the clamping force on the outer wall of the delivery tank. This facilitates the adjustment of the corresponding filling needles and improves the stability of filling quality. Attached Figure Description

[0030] like Figures 1 to 8 As shown, the top end of the gear 10 is fixedly connected to an extension shaft 11, the top end of the extension shaft 11 extends out of the outer wall of the movable groove 9, and the extension end of the extension shaft 11 is fixedly connected to a worm gear 12.

[0031] like Figures 1 to 8 As shown, a worm gear 13 is rotatably connected to the top of the lifting plate 6, and the worm gear 13 meshes with the worm wheel 12.

[0032] It should be noted that two bearing blocks are provided on the upper surface of the lifting plate 6, and the worm gear 13 is rotatably disposed between the two bearing blocks. By rotating the worm gear 13, the worm wheel 12 can be driven to rotate. A transverse sliding strip is provided on the inner wall of the lifting plate 6, and the toothed plate 8 is slidably connected to the outer wall of the sliding strip. At the same time, the sliding strip is used to stabilize the connection between the toothed plate 8 and the inner wall of the lifting plate 6.

[0033] like Figures 1 to 8 As shown, one end of the worm gear 13 extends out of the outer wall of the lifting plate 6, and a knob 14 is fixedly connected to the extended end of the worm gear 13. A clamping pad 16 is fixedly connected to the front end of the lifting plate 6.

[0034] It should be noted that the clamping pad 16 is used to cooperate with the clamping block 19 to stably clamp the outer wall of the conveying tank 17. The operator can manually turn the knob 14 to drive the worm gear 13 to rotate, thereby driving the worm wheel 12 to rotate synchronously.

[0035] like Figures 1 to 8 As shown, a lifting rod 7 is provided at the top of the fixed frame 2. The top of the lifting rod 7 is fixedly connected to the bottom of the lifting plate 6. A filling needle tube 18 is provided at the bottom of the lifting rod 7 and the conveying tank 17.

[0037] like Figures 1 to 8 As shown, the front end of the clamping block 19 is rotatably connected to an adjusting bolt 20, and the outer wall of the adjusting bolt 20 is threadedly connected to the inner wall of the clamping plate 15.

[0038] like Figures 1 to 8 As shown, a fixing screw 21 is fixedly connected to the front end of the toothed plate 8, and the fixing screw 21 is threadedly connected to the inner wall of the clamping plate 15.

[0039] It should be noted that a hinge shaft is provided on the left side of the front end of the filling syringe 18. The hinge shaft is used to hinge the clamping plate 15. The fixing screw 21 is provided on the right side of the front end of the lifting plate 6. A specified groove is provided on the right side of the clamping plate 15. When the clamping plate 15 is flipped by the hinge to clamp the conveying tank 17, the fixing groove will be fitted onto the outer wall of the fixing screw 21. At this time, the clamping between the clamping plate 15 and the toothed plate 8 can be sealed by the nut. The operator can manually rotate the adjusting bolt 20 to push the clamping block 19 to slide towards the clamping pad 16 and the outer wall of the conveying tank 17. The conveying tank 17 is clamped and fixed by the sliding engagement of the clamping pad 16.

[0040] like Figures 1 to 8As shown, a screw cap device 35 is provided at one end of the fixing frame 2 away from the top cover device 34, and a second cylinder 32 is fixedly connected to the front end of the fixing frame 2. A bottle clamping plate 33 is connected to the top of the output end of the second cylinder 32.

[0041] It should be noted that the operator can push the bottle clamping plate 33 by activating the second cylinder 32. After the bottle clamping plate 33 is pushed, the quota and conveying module 3 clamps and fixes the bottle for stable filling. The capping device 34 is composed of a fixing component and a conveying component. When the medicine bottle is conveyed to one end of the capping device 34, the fixing component fixes the medicine bottle, and then the conveying component moves the cap to the top of the medicine bottle. The bottom of the capping device 35 is equipped with multiple rotating arms, and the lower part of the arms is equipped with grippers. The grippers hold the bottle cap, and the arms rotate the grippers to screw the bottle cap to achieve assembly.

[0042] like Figures 1 to 8 As shown, a horizontal slide rod 24 is fixedly connected to the inner wall of the sliding frame 23. The outer wall of the horizontal slide rod 24 is slidably connected to the front end of the cleaning frame 25. A cleaning chamber 2501 is provided on the inner wall of the cleaning frame 25. Two sets of nozzles 29 are fixedly connected to the inner wall of the cleaning chamber 2501. Two sets of cleaning brushes 30 are symmetrically fixedly connected to the inner wall of the cleaning chamber 2501 and at the end near the nozzles 29.

[0043] like Figures 1 to 8 As shown, a drain pipe 31 is fixedly connected to the bottom of the cleaning frame 25, a water supply pipe 28 is fixedly connected to the front end of the cleaning frame 25, a first cylinder 26 is fixedly connected to the outer wall of the sliding frame 23, a push-pull rod 27 is fixedly connected to the output end of the first cylinder 26, and one end of the push-pull rod 27 is fixedly connected to the outer wall of the cleaning frame 25.

[0044] It should be noted that the inner wall of the nozzle 29 is connected to the inner wall of the water supply pipe 28, and the input end of the water supply pipe 28 is connected to the water source. Water is delivered to the output end of the nozzle 29 for spraying through the connection of the water supply pipe 28. However, when the operator starts the first cylinder 26, the first cylinder 26 pushes the push-pull rod 27 and the cleaning frame 25 through the output end, so that the cleaning frame 25 will slide laterally along the outer wall of the horizontal slide bar 24. The cleaning frame 25 will drive the cleaning brush 30 to slide synchronously. The surface of the filling syringe 18 is cleaned by the sliding of the cleaning brush 30.

[0045] Working principle and usage process:

[0046] Specifically, during the installation and debugging phase, the operator needs to flip the clamping plate 15 using its hinge. The clamping plate 15, by driving the clamping block 19 to flip, cooperates with the clamping pad 16 at the front end of the lifting plate 6 to clamp the outer wall of the delivery tank 17. The operator can adjust the clamping force by rotating the adjusting bolt 20 corresponding to the front of the filling syringe 18. The adjusting bolt 20 pushes and pulls the clamping block 19 through a threaded connection. At the same time, the operator can adjust the horizontal position of the toothed plate 8 and the clamping filling syringe 18 by rotating the knob 14. The knob 14 drives the worm gear 13 to rotate synchronously. The worm gear 13, through meshing, drives the worm wheel 12 to rotate. The worm wheel 12, through the connection of the extension shaft 11, drives the gear 10 to rotate. After the gear 10 rotates, through meshing, it drives the toothed plate 8 to slide horizontally at the front end of the lifting plate 6. The lifting plate 6, through the connection of the clamping plate 15 and the clamped filling syringe 18 and delivery tank 17, slides synchronously to adjust the filling position of the filling syringe 18. After adjustment, the operator needs to transport the medicine bottles to the inner wall of the conveying module 3 via a conveyor belt. The conveying module 3 then performs filling and capping of the medicine bottles. Under the intermittent transmission of the conveying module 3, the medicine bottles will reach one side of the lifting plate 6. At this point, the conveying module 3 stops transmission, and the second cylinder 32 is controlled to push the bottle clamping plate 33. The bottle clamping plate 33, under force, slides and clamps the medicine bottles. Multiple medicine bottles are clamped and fixed by the bottle clamping plate 33 in conjunction with the conveying module 3. After fixing, the operator controls the lifting rod 7 to move the lifting plate 6 up and down along the outer wall of the guide frame 5. The lifting plate 6 will move the clamped and fixed filling syringe 18 and the conveying can 17 up and down. Through this movement, the filling syringe 18 is inserted into the inner wall of the clamped medicine bottle for filling. After filling, the lifting rod 7 is controlled to move the lifting plate 6 and the filling syringe 18 upwards, and the second cylinder 32 is controlled to pull the bottle clamping plate 33. At this point, the filled medicine bottles are transported by the conveying module 3 to one side of the capping device 34.The medicine bottle is capped by the capping device 34, and then continues to be conveyed by the conveying module 3 to the capping device 35. The capping device 35 screws the medicine bottle onto the spray cap, completing the entire filling process on one side. After the spray filling is completed, the operator can use the cleaning frame 25 to clean the residual medicine on the surface of the filling syringe 18. During cleaning, the conveying module 3 needs to be stopped and the lifting plate 6 should be raised to the highest position to drive the filling syringe 18. Then, the operator pushes the sliding frame 23 to move the cleaning frame 25 along the top of the guide rail 22 towards the filling syringe 18. When one end of the cleaning frame 25 slides below the filling syringe 18, the operator needs to control the lifting rod 7 to move the lifting plate 6 to lift multiple bottles. The syringe 18 is inserted into the inner wall of the cleaning chamber. Then, the water supply pipe 28 is connected to a water source via a water pump pipe, and water is delivered through the water supply pipe 28 to the output end of the nozzle 29 for spraying. The front and rear sprays from the two sets of nozzles 29 clean the surface of the syringe 18 of the medicine. Next, the operator controls the first cylinder 26 to continuously push and pull the push-pull rod 27. The push-pull rod 27, under force, causes the cleaning frame 25 to slide reciprocally along the surface of the horizontal slide rod 24. The cleaning frame 25, in turn, causes the nozzles 29 and the cleaning brush 30 to slide synchronously. Through the reciprocating sliding of the nozzles 29 and the cleaning brush 30, the syringe 18 is dynamically cleaned. Finally, the cleaned water is discharged through the drain pipe 31, thus completing the cleaning process for the syringe 18.
