Description

Technical Field

[0001] The present invention relates to the technical field of filling machines, in particular to a novel aseptic filling machine. Background Art

[0002] In the production process of food and beverages such as juice, milk, and plant protein drinks, filling is an indispensable process. Existing PET bottle aseptic cold filling machines all use aseptic storage tanks to store materials that have been sterilized by UHT sterilizers.

[0003] An existing Chinese patent with authorization announcement number CN116462148A discloses an aseptic cold filling machine, comprising: a batching cylinder for storing unsterilized materials; a sterilizer having a sterilization pipeline connected to the batching cylinder, the sterilization pipeline being used to sterilize the unsterilized materials; a filling valve / filling valve group connected to the discharge end of the sterilization pipeline for filling sterile materials; a sterile valve having an inlet connected to the discharge end of the sterilization pipeline, an outlet connected to at least two parallel filling valves / filling valve groups, and another outlet connected to the sterilization pipeline or the batching cylinder via a sterile material return pipe; the batching cylinder forming a loop with the sterilization pipeline via a material inlet pipe, a material return pipe, and the sterilization pipeline. The present invention has the characteristics of simple structure, stable and efficient filling, and no need for a sterile storage tank.

[0004] Although the above-mentioned filling machine does not require a sterile storage tank, it does not have a dynamic sealing structure at the entrance where the bottles enter the filling machine, which makes the distance between the bottles too large. When the bottles stop moving during the filling process, air outside the filling machine enters the filling machine, thereby increasing the risk of contamination inside the filling machine and reducing the sterility level of the filling machine. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a new aseptic filling machine, aiming to solve the technical problem that the above-mentioned filling machine has no sealing structure at the bottle inlet, which reduces the aseptic degree of the filling machine.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A new aseptic filling machine includes an aseptic machine cover, an observation window and a mounting base, and further includes: A sealing assembly is provided on the sterile cover, effectively improving the sealing performance of the bottle inlet and outlet of the sterile cover; A first sterilization component is provided on the mounting base and is used to sterilize materials; A second sterilization component is provided on the sterile hood and is used to sterilize the interior of the sterile hood; A filling assembly is provided on the sterile machine cover and is used for filling work; The transport component is arranged on the first sterilization component and is used to transport the material from the first sterilization component to the filling component.

[0013] Preferably, the roughness of the contact surface between the slide rail and the slider is less than 0.8 μm.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: Through the setting of the sealing component, the driving motor is first used to drive the sterile plate cover on the rotating shaft to rotate, so that the sterile partition slidingly connected to the sterile plate cover rotates, and then the slider on the sterile partition is set on the slide rail, so that the sterile partition can be pulled along the slide rail and move tightly against the inner wall of the elliptical groove to perform telescopic movement, so that the sterile partition can play a sealing role without hitting the moving bottle due to rotation, thereby reducing the risk of the bottle being contaminated when entering the sterile machine cover, and improving the sterility level of the filling machine.

[0028] Reference Figures 1 to 7 A novel aseptic filling machine embodiment of the present invention is further described.

[0029] A novel aseptic filling machine includes an aseptic machine cover 1, an observation window 2 and a mounting base 3, and further includes: The sealing assembly is provided on the sterile cover 1, effectively improving the sealing performance of the bottle inlet and outlet of the sterile cover 1. The sealing assembly includes: A driving motor 4 is fixedly connected to the sterile cover 1; The rotating shaft 5 is fixedly connected to the output shaft of the driving motor 4; A groove 6 is provided on the aseptic cover 1, wherein the groove 6 is elliptical and the length of the major semi-axis of the ellipse is the same as the width of the through slot for entering and exiting the bottle; A sterile plate cover 7 is fixedly connected to the rotating shaft 5; A sterile partition 8 is slidably connected to the sterile plate cover 7; A slide rail 9 is provided on the sterile cover 1; The slider 10 is disposed on the slide rail 9 and is slidably connected to the sterile cover 1 . The roughness of the contact surface between the slide rail 9 and the slider 10 is less than 0.8 μm.

[0030] Start the driving motor 4, and the output shaft of the driving motor 4 rotates to drive the rotating shaft 5 fixedly connected to the output shaft of the driving motor 4 to rotate, thereby driving the sterile plate cover 7 fixedly connected to the rotating shaft 5 to rotate. The rotation of the sterile plate cover 7 drives the sterile partition 8 slidably connected to the sterile plate cover 7 to rotate, thereby driving the slider 10 fixedly connected to the sterile partition 8 to slide on the slide rail 9, and the sterile partition 8 slidably connected to the sterile plate cover 7 is extended by the slider 10 sliding on the slide rail 9, or retracted by the elliptical groove 6, so that when the bottle enters the sterile machine cover 1, the sterile plate cover 7 can temporarily block the through hole for entering and exiting the bottle to reduce the risk of contamination, and can also not touch the empty bottle moving in front, thereby reducing the risk of contamination inside the sterile machine cover 1.

[0031] Through the setting of the sealing component, the driving motor 4 is first used to drive the sterile plate cover 7 on the rotating shaft 5 to rotate, so that the sterile partition 8 slidingly connected to the sterile plate cover 7 rotates, and then the slider 10 sliding on the slide rail 9 on the sterile partition 8 is used to make the sterile partition 8 telescopically move along the slide rail 9 close to the inner wall of the elliptical groove 6 under the traction of the slider 10, so that the sterile partition 8 can play a sealing role without hitting the moving bottle due to rotation, thereby reducing the risk of the bottle being contaminated when entering the sterile machine cover 1, and improving the sterility level of the filling machine.

[0032] Reference Figures 1 to 7 The first sterilization component is provided on the mounting base 3 and is used to sterilize the material. The first sterilization component includes: An electrical control cabinet 11 is provided on the mounting base 3 and is fixedly connected to the mounting base 3; The UHT sterilizer 12 is fixedly connected to the mounting base 3; A feed pipe 13 is fixedly connected to the UHT sterilizer 12; A discharge pipe 14 is fixedly connected to the UHT sterilizer 12; A reflux transfer pipe 15 is provided on the UHT sterilizer 12 and is fixedly connected to the UHT sterilizer 12; The feed transfer pipe 16 is fixedly connected to the UHT sterilizer 12 .

[0033] The second sterilization component is provided on the sterile cover 1 and is used to sterilize the interior of the sterile cover 1. The second sterilization component includes: A mounting frame 17, fixedly connected to the sterile cover 1; A filter device 18 is provided on the mounting frame 17 and is detachably connected to the mounting frame 17; A fixing rod 19 detachably connected to the mounting frame 17 ; A mounting plate 20, fixedly connected to the fixing rod 19; The FUU laminar flow fan 21 is fixedly connected to the mounting plate 20 .

[0034] The material enters the UHT sterilizer 12 through the feed pipe 13 for sterilization, and then the FUU laminar flow fan 21 is started. The sterile air generated by the FUU laminar flow fan 21 and filtered by the filter device 18 enters the sterile machine cover 1, providing a sterile environment for the inside of the filling machine, achieving the effect of sterilization and disinfection.

[0035] Reference Figures 1 to 7 The filling assembly is provided on the aseptic cover 1 and is used for filling. The filling assembly includes: The filling device 22 is provided on the sterile cover 1 and is fixedly connected to the sterile cover 1; A flow meter 23 is fixedly connected to the filling device 22; A first branch pipe 24 is fixedly connected to the filling device 22; A filling valve 25 is fixedly connected to the first branch pipe 24; The second branch pipe 26 is fixedly connected to the filling valve 25; The branch pipe 27 is fixedly connected to the second branch pipe 26 .

[0036] Several filling valves 25 on the same side are opened, while the filling valves 25 on the other side are closed. The sterile material enters the branch pipe 27 from the material transport pipe 31, and then enters the second branch pipe 26 and the opened filling valve 25 from the branch pipe 27. Then, the opened filling valve 25 passes through the first branch pipe 24 and enters the filling device 22 to fill the bottle. When the flow meter 23 on the filling device 22 measures enough sterile material flowing into the bottle, the filling valve 25 on this side is closed, and then the filling valve 25 on the other side is opened for filling. This cycle is repeated, so that the sterile material is continuously and stably supplied in the closed pipeline, thereby achieving the effect of omitting the sterile buffer tank.

[0037] Reference Figures 1 to 7 , a transport component, provided on the first sterilization component, for transporting the material from the first sterilization component to the filling component, the transport component comprising: The sterile material reflux pipe 28 is provided on the reflux transfer pipe 15 and is fixedly connected to the reflux transfer pipe 15; The sterile material inlet pipe 29 is fixedly connected to the feed transfer pipe 16; The bracket 30 is provided on the sterile cover 1 and is fixedly connected to the sterile cover 1; The material transport pipe 31 is fixedly connected to the bracket 30 and is fixedly connected to the diversion pipe 27; A sterile transfer tube 32 is fixedly connected to the material transport tube 31 , the sterile transfer tube 32 is fixedly connected to the sterile material return tube 28 , and the sterile transfer tube 32 is fixedly connected to the sterile material inlet tube 29 ; The sterile control valve 33 is fixedly connected to the sterile transfer tube 32 .

[0038] The sterilized sterile material enters the sterile material inlet pipe 29 through the feed transfer pipe 16, and then enters the material transport pipe 31 through the sterile transfer pipe 32. At this time, the sterile control valve 33 on the transfer pipe only allows the sterile material to flow in the sterile material inlet pipe 29 and cannot flow into the sterile material return pipe 28. Start the sterile control valve 33, so that the sterile control valve 33 closes the part of the sterile transfer pipe 32 where the sterile material inlet pipe 29 is located, and opens the part of the sterile transfer pipe 32 where the sterile material return pipe 28 is located, so that the sterile material enters the UHT sterilizer 12 from the sterile material return pipe 28 through the reflux transfer pipe 15, thereby achieving the purpose of transporting sterile materials.

[0039] Working principle: Refer to Figures 1 to 7 The filling machine starts the air conveying channel to move the empty bottle. When the empty bottle is about to approach the sterile partition 8, the driving motor 4 is started. The output shaft of the driving motor 4 rotates to drive the rotating shaft 5 fixedly connected to the output shaft of the driving motor 4 to rotate, thereby driving the sterile plate cover 7 fixedly connected to the rotating shaft 5 to rotate. The rotation of the sterile plate cover 7 drives the sterile partition 8 slidably connected to the sterile plate cover 7 to rotate, thereby driving the slider 10 fixedly connected to the sterile partition 8 to slide on the slide rail 9, and the sterile partition 8 slidably connected to the sterile plate cover 7 is extended by the slider 10 sliding on the slide rail 9, or retracted by the elliptical groove 6, so that when the bottle enters the sterile cover 1, the sterile plate cover 7 can temporarily block the through hole for entering and exiting the bottle to reduce the risk of contamination, and can also not touch the empty bottle moving in front, thereby reducing the risk of contamination inside the sterile cover 1; The material enters the UHT sterilizer 12 through the feed pipe 13 for sterilization, and then the FUU laminar flow fan 21 is started. The sterile air generated by the FUU laminar flow fan 21 and filtered by the filter device 18 enters the sterile machine cover 1, providing a sterile environment for the inside of the filling machine; Reference Figures 1 to 7The sterilized sterile material enters the sterile material inlet pipe 29 through the feed transfer pipe 16, and then enters the material transport pipe 31 through the sterile transfer pipe 32. At this time, the sterile control valve 33 on the transfer pipe only allows the sterile material to flow in the sterile material inlet pipe 29 and cannot flow into the sterile material return pipe 28. When the bottles sterilized by the filling machine arrive at the filling device 22, several filling valves 25 on the same side are opened, and the filling valves 25 on the other side are closed at the same time. The sterile material enters the diversion pipe 27 from the material transport pipe 31. , then enters the second branch pipe 26 and the opened filling valve 25 through the diversion pipe 27, and then enters the filling device 22 through the opened filling valve 25 through the first branch pipe 24 to fill the bottle. When the flow meter 23 on the filling device 22 measures the volume of sterile material flowing into the bottle, the filling valve 25 on this side is closed, and the filling valve 25 on the other side is opened for filling. This cycle is repeated, so that the sterile material is continuously and stably supplied in the closed pipeline, achieving the effect of omitting the sterile buffer tank. When the filling machine stops due to a fault, the aseptic control valve 33 is started to close the part of the aseptic transfer pipe 32 where the sterile material inlet pipe 29 is located, and open the part of the aseptic transfer pipe 32 where the sterile material return pipe 28 is located, so that the sterile material enters the UHT sterilizer 12 from the sterile material return pipe 28 through the reflux transfer pipe 15, or returns to the batching part through the discharge pipe 14 of the UHT sterilizer 12, thereby reducing the risk of material contamination during shutdown.
