Description

Technical Field

[0001] This invention relates to the field of vial packaging production, and in particular to a capping machine with aluminum shavings collection. Background Technology

[0002] The process of filling vials typically includes filling the vial with the medication, capping, and crimping. Capping involves using an automatic transfer mechanism to sequentially press a rubber stopper and an aluminum cap into the vial neck. Crimping involves using an automatic crimping machine to tightly press the aluminum cap onto the vial neck to form a seal.

[0003] In existing technologies, to avoid the impact of aluminum shavings from the capping process on the production environment and pharmaceutical contamination, the filling and capping processes are performed on separate production lines. This leads to reduced production efficiency and increased space requirements, which has certain shortcomings. Furthermore, a separate capping production line should be equipped with appropriate ventilation devices, and operators must promptly and thoroughly remove the aluminum shavings generated during production and clean and disinfect the return air vents after capping. This increases personnel operating costs during the production process. Summary of the Invention

[0004] The present invention provides a capping machine with aluminum shavings collection, including a capping cutter head, a dust collection device, and a capping sealing device. The capping sealing device is provided with a cavity for accommodating the cap portion of a vial. The dust collection device is connected to the cavity and is used to adsorb aluminum shavings generated during the capping process.

[0005] Furthermore, the crimping sealing device includes: a stainless steel crimping cover and a transition joint. The stainless steel crimping cover and the transition joint are fixedly connected by threads. The crimping cutter head is located inside the stainless steel crimping cover. The stainless steel crimping cover and the crimping cutter head can move up and down synchronously. The transition joint is provided with an interface for connecting to a dust collection device, thereby connecting the dust collection device to the cavity.

[0006] Furthermore, the lower end face of the stainless steel cap is provided with a round hole, the diameter of which is 3-4 mm wider than the diameter of the vial.

[0007] Furthermore, the stainless steel capping cover is fixed on the capping lifting shaft. As the capping lifting shaft descends, the stainless steel capping cover and the transition joint wrap around the capping cutter head and move downwards simultaneously, allowing the vial cap to enter the cavity. As the capping lifting shaft rises, the vial cap exits the cavity.

[0008] Furthermore, the vacuuming device includes: a vacuuming device outer cover, a vacuuming device upper cover, a vacuuming fan, and a filter element. The vacuuming device upper cover covers the vacuuming device outer cover, the filter element is located inside the vacuuming device outer cover, the vacuuming fan is located below the vacuuming device outer cover, and the vacuuming device upper cover is connected to the cavity through a pipe.

[0009] Furthermore, the top cover of the vacuum cleaner is removable, and an O-ring is provided at the lower end of the top cover.

[0010] Furthermore, the capping sealing device includes: a telescopic protective cover and an openable lower sealing dust suction cover. The telescopic protective cover and the capping cutter head can move up and down. The telescopic protective cover and the openable lower sealing dust suction cover can surround and seal the vial cap. The dust suction fan unit connects the openable lower sealing dust suction cover and the particulate matter collection unit.

[0011] Furthermore, the opening and closing bottom-sealed dust hood includes two opposing semi-cylindrical grooves.

[0012] Furthermore, the radius of the groove is 1-2 mm wider than the radius of the vial.

[0013] Furthermore, a sealing ring is provided on the inner wall of the groove.

[0014] Furthermore, the capping machine is arranged above the vial conveyor belt, which is used to transport vials, and the two semi-cylindrical grooves are arranged on both sides of the conveyor belt.

[0015] Furthermore, the side of the opening and closing type sealed dust hood is provided with a pipe connected to the dust collection device.

[0016] Furthermore, the vacuuming device includes a vacuuming fan unit and a particulate matter collection unit. The vacuuming fan unit includes at least one power fan. The particulate matter collection unit is snap-connected to the vacuuming fan unit, and a filter screen corresponding to the power fan is provided inside the particulate matter collection unit.

[0017] Furthermore, a sealing ring is provided at the lower end of the telescopic protective cover.

[0018] In this invention, the filling, capping, and coring processes of vials are completed on a stepping track conveyor mechanism. This means that the entire process is completed on a single production line during vial transport, improving efficiency and minimizing space occupancy. Furthermore, the use of a dust collection device creates a closed environment during the capping process, effectively collecting aluminum shavings and preventing product and environmental contamination. The collection design is also simple and easy to implement. Attached Figure Description

[0026] See Figure 1-4 The first embodiment of the capping machine with aluminum shavings collection of the present invention includes a servo lifting module 1, a guide fixing structure 5, a capping cutter head 12, a pipeline 8, a dust collection device 20, a stainless steel capping cover 58, and a transition joint 59.

[0027] After the vial 13 is capped and corked on the stepping track conveyor 14, it is transported to the capping station, which is located below the capping machine. The stainless steel capping cover 58 and the transition joint 59 cooperate to form a cavity that encloses the cap portion of the vial 13. The dust collection device 20 is connected to the cavity and is used to absorb aluminum shavings generated during the capping process.

[0028] The diameter of the lower circular hole of the stainless steel capping cover 58 is 3-4 mm wider than the diameter of the vial. The stainless steel capping cover 58 is fixed on the capping lifting shaft. The stainless steel capping cover 58 and the transition joint 59 are fixedly connected by threads. The capping cutter head 12 is located inside the stainless steel capping cover 58. The stainless steel capping cover 58 and the capping cutter head 12 can move up and down synchronously. During the capping process, the vial 13 enters the capping sealing space through the lower circular hole of the stainless steel capping cover 58 to complete the capping operation. According to the different heights of the vials, the control system adjusts the descent height of the capping cutter head 12 to realize the capping process of vials of different specifications.

[0029] One end of the transition joint 59 is provided with a pipe 8 connected to the vacuum cleaner 20, and the upper cover 62 of the vacuum cleaner has an interface with the same diameter as the pipe 8. The upper cover 62 of the vacuum cleaner can be pulled out, and the filter element 55 can be replaced by opening and closing the upper cover 62. An O-ring is provided at the lower end of the upper cover 62, providing a good seal with the outer cover 60 of the vacuum cleaner. The vacuum fan 61 is located at the lower end of the vacuum cleaner 20, and an exhaust port is provided at the lower end of the vacuum cleaner 20. To prevent aluminum shavings from leaking and polluting the environment, a layer of sponge is placed between the lower end of the vacuum fan 61 and the exhaust port.

[0030] The vacuum fan 61 consists of a high-speed, quiet power fan. During the capping process, the vacuum fan 61 starts, creating negative pressure to draw aluminum shavings generated during the capping process into the filter element 55 through the pipe 8. The filter element 55 is a consumable material, designed for easy replacement and disassembly.

[0031] In use, after the vials 13 have been capped and corked, they are conveyed by a stepping conveyor mechanism 14 to complete the filling, corking, and capping process, and are then pushed to the capping station. The control system initiates the capping program. The stainless steel capping cover 58 and the transition joint 59 enclose the capping cutter head 12 and move downwards simultaneously. The vial 13 passes through the lower circular hole of the stainless steel capping cover 58, and the vial cap enters the capping sealing device. The capping cutter head 12 performs the capping, and the aluminum shavings generated during the process are collected by the dust extraction fan 61 along the pipe 8 into the filter element 55. After capping is completed, the stainless steel capping cover 58 and the transition joint 59 enclose the capping cutter head 12 and move upwards simultaneously, and the vial cap exits the capping sealing device. The vial 13 is then conveyed by the stepping conveyor mechanism 14 to the next station. The vials complete the capping process sequentially via the stepping track conveyor mechanism 14. Because the capping process has an aluminum shavings collection function, it solves the problem of aluminum shavings polluting the product and the environment. Therefore, the vial 13 is conveyed on the stepping track conveyor mechanism 14, and the filling, stoppering, capping and capping processes can be completed in sequence, realizing the purpose of completing the operation on the same production line, saving space and time.

[0032] See Figure 5-7 The second embodiment of the capping machine with aluminum shavings collection of the present invention includes a servo lifting module 1, a guide fixing structure 5, a telescopic protective cover 6, an opening and closing lower sealing dust suction cover 7, a pipeline 8, a dust suction device 20, and a capping cutter head 12.

[0033] After the vial 13 is capped and corked on the stepping track conveyor 14, it is transported to the capping station, which is located below the capping machine. The telescopic protective cover 6 and the opening and closing lower sealing dust suction cover 7 work together to form a sealed space that encloses the vial 13.

[0034] The opening and closing type bottom-sealed dust collection cover 7 includes two opposing semi-cylindrical grooves, the radius of which is 1-2 mm wider than the radius of the vial, and contains a silicone sealing ring. The two semi-cylindrical grooves are distributed on both sides of the stepping track conveying mechanism 14, and the opening and closing operation is controlled by the drive mechanism.

[0035] The telescopic protective cover 6 has the same length and width as the openable lower-sealed dust extraction cover 7 when closed. A silicone sealing ring is located at the lower end of the telescopic protective cover 6. The telescopic protective cover 6 can move up and down; when it reaches the lower end, it forms a sealed space with the upper end of the openable lower-sealed dust extraction cover 7. Simultaneously, the capping cutter head 12 moves downward, completing the capping operation within the sealed space. Depending on the height of the vials, the control system adjusts the descent height of the capping cutter head 12 to achieve the capping process for vials of different sizes.

[0036] The side of the openable, lower-sealed dust extraction hood 7 is equipped with a pipe 8 connected to the dust extraction device 20. The dust extraction fan unit 9 and the particulate matter collection unit 10 are fixedly connected by snap-fit. During the capping process, the dust extraction fan unit 9 is turned on, using suction to draw the aluminum shavings generated during the capping process into the particulate matter collection unit 10. This avoids the impact of aluminum shavings on the production environment and pharmaceutical contamination during the capping process.

[0037] The vacuum fan unit 9 consists of three high-speed, silent power fans 17, evenly distributed along the circumference. When the high-speed, silent power fans 17 are activated, they create negative pressure, drawing aluminum shavings generated during the capping process through pipes 8 into the particulate collection unit 10. To prevent aluminum shavings from adhering to the high-speed, silent power fans 17 and affecting performance, the fans are designed with a certain degree of smoothness to avoid adhesion. The particulate collection unit 10 consists of three nano-scale filters 18, corresponding to the power fans 17. The filters 18 are consumable materials, allowing for easy replacement and disassembly.

[0038] In use, after the vials 13 have been capped and corked, they are conveyed by a stepping conveyor mechanism 14 to complete the filling, capping, and corking process, and then pushed to the capping station. The control system initiates the capping program. The opening and closing lower sealing dust hood 7 closes, sealing from the bottle body. As the capping cutter head 12 moves downward, the telescopic protective cover 6 presses against the opening and closing lower sealing dust hood 7 to seal. The dust collection device 20 opens, and the capping cutter head 12 performs capping. The aluminum shavings generated during the process are collected by the dust collection fan unit 9 along the pipe 8 into the particulate matter collection unit 10. After capping is completed, the opening and closing lower sealing dust hood 7 opens, the capping cutter head 12 and the telescopic protective cover 6 rise, and the vials 13 are pushed to the next station by the stepping conveyor mechanism 14. The vials complete the capping process sequentially via the stepping track conveyor mechanism 14. Because the capping process has an aluminum shavings collection function, it solves the problem of aluminum shavings polluting the product and the environment. Therefore, the vial 13 is conveyed on the stepping track conveyor mechanism 14, and the filling, stoppering, capping and capping processes can be completed in sequence, realizing the purpose of completing the operation on the same production line, saving space and time.

[0039] Those skilled in the art will understand that the main difference between the two embodiments is the structure of the crimping sealing device. Although the structure of the dust collection device is also different for different embodiments, the function of the dust collection device in the two embodiments is similar, which is to suck out the aluminum shavings after crimping from the cavity inside the crimping sealing device. Therefore, the dust collection devices of Embodiment 1 and Embodiment 2 can be substituted for each other to complete the collection of aluminum shavings. The connection method after substitution is a known technology and will not be described in detail.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
