Description

Technical Field

[0001] The invention belongs to the technical field of BFS aseptic filling machine, and in particular, it is a BFS aseptic filling machine device with a filling needle spacing adjustment mechanism. Background Technology

[0002] In the production processes of modern food, pharmaceutical, and cosmetic industries, aseptic filling machines are key equipment for ensuring product quality and safety.

[0003] The BFS aseptic filling machine includes dispensing equipment, delivery pipelines, and bottle molds. When filling different containers, the delivery pipelines and bottle molds need to be adjusted and switched according to the different container sizes, and the filling needles also need to be switched to be compatible.

[0004] Therefore, traditional BFS aseptic filling machines typically employ a fixed needle spacing design, meaning the distance between the filling needles is preset and cannot be adjusted according to different container sizes. While this fixed spacing design performs well in certain specific applications, it has significant limitations when dealing with multi-variety, small-batch production.

[0005] Traditional aseptic filling machines have a fixed needle spacing, which cannot be adjusted for different container sizes. This forces companies to frequently change the entire filling system or use different equipment when producing products of various sizes, increasing equipment investment and maintenance costs. When switching to different container sizes, operators need to manually change the filling needles, which is not only time-consuming and labor-intensive but also prone to human error, affecting production efficiency and product quality. Summary of the Invention

[0006] The purpose of this invention is to provide a BFS aseptic filling machine device with a filling needle spacing adjustment mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the invention provides the following technical solution: a BFS aseptic filling machine device with a needle spacing adjustment mechanism, comprising a filling machine platform, a filling liquid tank mounted on the top surface of the filling machine platform, an inverted L-shaped fixed plate fixed below one side of the filling liquid tank and located on the top surface of the filling machine platform, a conveyor mounted on the side of the L-shaped fixed plate facing away from the filling liquid tank and located on the top surface of the filling machine platform, and a lifting plate embedded in the top surface of the L-shaped fixed plate near the conveyor; A first sliding groove is horizontally opened at the middle of the top surface of the lifting plate. Multiple first sliding blocks are evenly arranged in the first sliding groove. A first filling needle is vertically arranged on the bottom surface of each first sliding block. An inverted U-shaped frame rod is welded above the lifting plate and on the top surface of the L-shaped fixed upright plate. A spacing adjustment lifting plate is raised and lowered inside the U-shaped frame rod. A second sliding groove is horizontally opened inside the spacing adjustment lifting plate. Multiple second sliding blocks are evenly arranged in the second sliding groove. A second filling needle is vertically arranged on the bottom surface of each second sliding block. When the spacing adjustment lifting plate descends, each second filling needle is inserted between two adjacent first sliding blocks.

[0008] In a preferred embodiment, the top surface of the L-fixed upright plate is provided with a rectangular opening for the lifting plate to fit properly, and an inverted L-shaped hoisting plate is welded to one side of the lifting plate and on the top surface of the L-fixed upright plate.

[0009] In this preferred embodiment, a hydraulic lifting column is fixedly installed on the inner top wall of the L-shaped lifting plate by bolts, and the bottom lifting end of the hydraulic lifting column is fixedly connected to the top surface of the lifting plate by bolts.

[0010] In this preferred embodiment, an electric lifting column is fixed at the middle position of the inner top wall of the U-shaped frame, and the bottom free end of the electric lifting column is fixedly connected to the middle position of the top surface of the spacing adjustment lifting plate.

[0011] In a preferred embodiment, the outer wall of one side of the spacing adjustment lifting plate is provided with multiple spacing screw holes at equal intervals, and locking bolts are threaded into the spacing screw holes. The screw end of the locking bolt is threadedly fixed to the second slider seat in the first slide groove.

[0012] In a preferred embodiment, the inner walls of both sides of the second slide groove are provided with positioning slide grooves, and the outer walls of both sides of each first slider seat are provided with positioning sliders that are slidably connected in the positioning slide grooves. Each positioning slider is securely connected to the positioning slide groove by a magnetic attraction component.

[0013] In a preferred embodiment of this scheme, the magnetic attraction component includes a first magnet block bonded to the inner wall of each of the two positioning grooves and a second magnet block bonded to the outer wall of each positioning slider.

[0014] In this preferred embodiment, the top surface of one side of the spacing adjustment lifting plate and the second slide groove are both provided with scale lines, so that each of the first slider seats is equally spaced in the second slide groove and each of the second slider seats is equally spaced in the first slide groove.

[0015] In this preferred embodiment, the bottom surface of the filling tank has a filling valve pipe, the top surface of the U-shaped frame rod is fixedly installed with a first liquid pipe, and the side of the U-shaped frame rod located on the top surface of the L-shaped fixed plate is fixedly installed with a second liquid pipe.

[0016] In a preferred embodiment, both the first slider seat and the second slider seat have a connecting tube running longitudinally through them. The bottom end of the connecting tube is integrally formed with an externally threaded connecting tube, which is threadedly connected to the first filling needle and the second filling needle.

[0017] Compared with existing technologies, the technical effects and advantages of the invention are as follows: This BFS aseptic filling machine with a needle spacing adjustment mechanism features a first and second chute between a lifting plate and a spacing adjustment lifting plate, along with multiple first and second slider seats. This allows for flexible adjustment of the distance between the first and second filling needles to accommodate containers of different sizes. This design significantly improves the equipment's versatility and adaptability, meeting the filling needs of various container sizes and shapes without frequent replacements of the entire filling system. The spacing adjustment lifting plate is moved up and down by an electric lifting column, enabling rapid adjustment of the second filling needle's position and instantaneous needle spacing adjustment. This feature is particularly suitable for multi-variety, small-batch production on a production line, reducing changeover time and improving production efficiency.

[0018] The coordinated operation of the hydraulic and electric lifting columns ensures smooth and precise raising and lowering of the filling needles. Precise control of the lifting process by the control system prevents liquid splashing or container damage caused by sudden movements, guaranteeing accurate filling volumes for each container. The graduated markings provide operators with an intuitive reference, helping them to more accurately adjust the needle spacing and ensuring consistency and stability in every filling cycle. This design not only improves filling accuracy but also simplifies the operation process and reduces human error.

[0019] The use of the first and second magnets ensures that the positioning slider is firmly attached to the positioning groove, preventing slippage. This design not only guarantees the stability of the filling needle during operation but also extends the equipment's lifespan and reduces maintenance costs. The external threaded connecting tube design makes the filling needle easy to disassemble and clean, ensuring the equipment's hygiene standards. Simultaneously, the removable end cap design facilitates the inspection and maintenance of internal components, further improving the equipment's reliability and durability.

However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with the invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of the invention, and are explained here together.

[0025] Example 1 This solution provides, for example Figures 1 to 4The illustrated BFS aseptic filling machine device with a needle spacing adjustment mechanism includes a filling machine platform 1. A filling liquid tank 3 is mounted on the top surface of the filling machine platform 1. An inverted L-shaped fixed plate 7 is fixed below one side of the filling liquid tank 3 and on the top surface of the filling machine platform 1. A conveyor 6 is mounted on the side of the L-shaped fixed plate 7 facing away from the filling liquid tank 3 and on the top surface of the filling machine platform 1. A lifting plate 12 is embedded in the top surface of the L-shaped fixed plate 7 near the conveyor 6. A first chute 11 is horizontally opened in the middle of the top surface of the lifting plate 12. Multiple first slider seats 17 are evenly arranged in the first chute 11. A first filling needle 8 is longitudinally arranged on the bottom surface of each first slider seat 17. An inverted U-shaped support rod 10 is welded to the top surface of the fixed vertical plate 7 above 12. A spacing adjustment lifting plate 19 is installed inside the U-shaped support rod 10. A second sliding groove 16 is opened horizontally inside the spacing adjustment lifting plate 19. Multiple second sliding blocks 20 are evenly arranged in the second sliding groove 16. A second filling needle 22 is arranged longitudinally on the bottom surface of each second sliding block 20. When the spacing adjustment lifting plate 19 is lowered, each second filling needle 22 is inserted between two adjacent first sliding blocks 17. The spacing of the filling needles is changed by the lowering and lowering of the second filling needles 22 and the raising of the plate, so as to meet the filling of containers of different sizes and the spacing adjustment of different containers.

[0026] In this embodiment, the top surface of the L fixed plate 7 is provided with a rectangular opening for the lifting plate 12 to fit properly, and an inverted L lifting plate 13 is welded to one side of the lifting plate 12 and on the top surface of the L fixed plate 7.

[0027] In this embodiment, a hydraulic lifting column 14 is fixedly installed on the inner top wall of the L-lifting plate 13 by bolts. The bottom lifting end of the hydraulic lifting column 14 is fixedly connected to the top surface of the lifting plate 12 by bolts, so that when the hydraulic lifting column 14 drives the lifting plate 12 to rise and fall, it drives the first filling needle 8 to be inserted into the container to be filled.

[0028] In this embodiment, an electric lifting column 21 is fixed at the middle position of the inner top wall of the U-shaped frame 10, and the bottom free end of the electric lifting column 21 is fixedly connected to the middle position of the top surface of the spacing adjustment lifting plate 19. This allows the electric lifting column 21 to drive the spacing adjustment lifting plate 19 to rise and fall, so that the second filling needle 22 rises and falls longitudinally between two adjacent first filling needles 8.

[0029] In this embodiment, a plurality of spacing screw holes 23 are equally spaced on one side of the outer wall of the spacing adjustment lifting plate 19. Locking bolts 24 are threadedly connected to the spacing screw holes 23, and the screw end of the locking bolt 24 is threadedly fixed to the second slider seat 20 in the first slide groove 11.

[0030] In this embodiment, positioning grooves 28 are provided on both inner walls of the second slide groove 16, and positioning sliders 30 are provided on both outer walls of each first slider seat 17 and are slidably connected in the positioning grooves 28. Each positioning slider 30 is securely connected to the positioning grooves 28 by a magnetic component.

[0031] In this embodiment, the magnetic attraction component includes a first magnet block 29 respectively bonded to the inner wall of the two positioning slide grooves 28 and a second magnet block 31 bonded to the outer wall of each positioning slider 30. When the first slider seat 17 is slidably connected in the second slide groove 16, the two positioning sliders 30 of the first slider seat 17 are adapted to the positioning slide groove 28 and slide in the positioning slide groove 28, thereby adjusting the position of the first slider seat 17 in the second slide groove 16, and the first magnet block 29 and the second magnet block 31 magnetically attract each other.

[0032] In this embodiment, scale lines 27 are provided on one side of the top surface of the spacing adjustment lifting plate 19 and the second slide groove 16, so that each first slider seat 17 is equally spaced in the second slide groove 16 and each second slider seat 20 is equally spaced in the first slide groove 11.

[0033] In this embodiment, a filling valve pipe 4 is provided on the bottom surface of the filling liquid tank 3, a first liquid pipe 5 is fixedly installed on the top surface of the U-shaped support rod 10, a second liquid pipe 15 is fixedly installed on one side of the U-shaped support rod 10 and on the top surface of the L fixed upright plate 7, and a three-way branch pipe is connected to the free end of the filling valve pipe 4. One output end of the three-way branch pipe is connected to the first liquid pipe 5 through the first connecting hose 9, and the other output end is connected to the second liquid pipe 15 through the third connecting hose 33. At the same time, the ends of the first connecting hose 9 and the third connecting hose 33 near the filling valve pipe 4 are equipped with solenoid valves to control the filling liquid in the filling liquid tank 3 to flow through the filling valve pipe 4 to the first connecting hose 9 or the third connecting hose 33.

[0034] In this embodiment, both the first slider seat 17 and the second slider seat 20 have a connecting pipe running longitudinally through them. The bottom end of the connecting pipe is integrally formed with an external threaded connecting pipe 32, which is threadedly connected to the first filling needle 8 and the second filling needle 22. The top end of the connecting pipe extends to the upper outside of the first slider seat 17 and the second slider seat 20. The top of the first slider seat 17 is connected to the second liquid pipe 15 through the second connecting hose 18, so that the filling liquid in the second liquid pipe 15 flows from the second connecting hose 18 to the first filling needle 8. The top of the second slider seat 20 is connected to the first liquid pipe 5 through the branch hose 26, so that the filling liquid in the first liquid pipe 5 flows from the branch hose 26 to the second filling needle 22, thereby enabling the first filling needle 8 and the second filling needle 22 to fill the container in the conveyor 6. Both ends of the spacing adjustment lifting plate 19 are bolted with removable end caps 25, which block the first slide groove 11. Removing the removable end caps 25 facilitates the removal of the second slider seat 20. The external threaded connecting pipe 32 is an adapter. When it is necessary to replace the first filling needle 8 or the second filling needle 22, the external threaded connecting pipe 32 facilitates the removal of the first filling needle 8 and the second filling needle 22, and also facilitates the replacement of filling needles of different specifications. Two support columns 2 are symmetrically installed on the top surface of the filling machine platform 1. The top ends of the two support columns 2 are fixedly connected to the bottom surface of the filling liquid tank 3 to support the filling liquid tank 3.

[0035] Example 2 In this embodiment, one of the first connecting hoses 9 and the third connecting hose 33 is disconnected from the end near the filling valve pipe 4, so that the first connecting hose 9 or the third connecting hose 33 is connected to another barrel of different filling liquid in the workshop. Driven by the water pump, the filling liquid different from that in the filling liquid tank 3 can also be filled into the required container on the conveyor 6, so that the first filling needle 8 and the second filling needle 22 can perform filling operations simultaneously, so that different liquids can be filled into the container on the conveyor 6.

[0036] Working principle The BFS aseptic filling machine with a needle spacing adjustment mechanism places empty containers to be filled on conveyor 6, ready for automatic transport. The positions of the first slider seat 17 and the second slider seat 20 are pre-adjusted according to the container specifications to ensure the spacing between the first filling needle 8 and the second filling needle 22 matches the container. Conveyor 6 starts operating, orderly feeding empty containers into the filling area. As the container passes under the L-shaped fixed upright 7, it gradually approaches the first filling needle 8 and the second filling needle 22. When the container reaches the predetermined position, the conveyor temporarily stops to ensure each container is accurately aligned under the corresponding filling needle. At this time, the container position is precisely controlled by the conveyor speed and control system to ensure the accuracy of each filling operation.

[0037] The hydraulic lifting column 14 is activated, causing the lifting plate 12 and its first filling needle 8 to descend slowly. Simultaneously, the electric lifting column 21 is also activated, causing the spacing adjusting lifting plate 19 and its second filling needle 22 to descend synchronously. The first filling needle 8 and the second filling needle 22 are inserted into the opening of the container, ensuring the needle tip is fully inside the container without touching the bottom. At this time, the first magnet 29 and the second magnet 31 cause the positioning slider 30 to be firmly attached to the positioning groove 28, preventing slippage.

[0038] The appropriate filling path is selected by the PLC control system as needed. For example, if the first filling needle 8 is used, the solenoid valve in the first connecting hose 9 is opened, allowing liquid to flow from the filling tank 3 through the first liquid pipe 5 to the first filling needle 8. If the second filling needle 22 is used, the solenoid valve in the third connecting hose 33 is opened, allowing liquid to flow through the second liquid pipe 15 to the second filling needle 22. Liquid flows through the filling valve pipe 4 and the corresponding first connecting hose 9 and third connecting hose 33 into the first filling needle 8 and the second filling needle 22, and is finally injected into the container. The filling volume is precisely controlled by the control system to ensure that each container receives the set liquid volume. The scale line 27 is used to assist the operator in monitoring the position of the filling needles to ensure the correct filling position.

[0039] Once the liquid filling is complete, the PLC control system closes the corresponding solenoid valves, stopping the liquid flow. Subsequently, the hydraulic lifting column 14 and the electric lifting column 21 start simultaneously, causing the first filling needle 8 and the second filling needle 22 to slowly rise and be pulled out of the container. After the filling needles are completely removed from the container, the lifting plate 12 and the spacing adjustment lifting plate 19 return to their initial positions, ready to receive the next container.

[0040] Conveyor 6 restarts, carrying the filled containers away from the filling area and to the next process, such as sealing and labeling. At the same time, new empty containers are sent into the filling area, ready for the next round of filling.

[0041] By adjusting the position of the second slider seat 20 in the second slide groove 16 and fixing it with the locking bolt 24, the distance between the second filling needle 22 and the first filling needle 8 can be flexibly changed to accommodate containers of different sizes. This design greatly improves the versatility and production efficiency of the equipment.
