[0002] Formulated foods for special medical purposes refer to formula foods that are specially processed and prepared to meet the special needs of nutrients or diets for people with restricted food intake, digestion and absorption disorders, metabolic disorders or specific disease states. They include special medical purpose infant formula foods for children aged 0 to 12 months and special medical purpose formula foods for people over 1 year old. They must be used under the guidance of a doctor or clinical nutritionist and play an important role in nutritional support for the treatment, rehabilitation and maintenance of body functions of the consumers.

[0003] The prior art discloses some patent documents related to quantitative filling devices. The Chinese patent with application number CN202122196501.X discloses a quantitative filling device for special medical formula food, including a filling plate and a filling assembly, the filling plate is provided with a plurality of card interfaces and a smoothing member provided at each card interface, the filling assembly includes a storage box and a filling member connected to the storage box, the filling member has a first filling port and a second filling port corresponding to the packaging can located at the card interface, and a material discharge channel connecting the storage box and the first filling port and the second filling port, the flow rate of the first filling port is greater than the flow rate of the second filling port; wherein, the filling assembly also includes a first valve provided at the first filling port and a second valve provided at the second filling port, the first filling port quickly fills the packaging can at the card interface, after the first filling port is filled, the smoothing member is used to smooth the material at the filling port of the packaging can, and the second filling port again slowly fills the packaging can at the card interface. There will not be too much material overflowing outside the filling port, reducing the waste of materials.

[0004] The prior art usually adopts a fixed-point filling method. During filling, when the conveying mechanism transports the packaging bottle to the filling port, the transfer component transfers the packaging bottle to the parking platform, and the fixing components on both sides fix the packaging bottle, or the fixing components on both sides directly lift the packaging bottle slightly and clamp it. After fixation, the filling port can be moved down for filling. At this time, the transportation of subsequent packaging bottles is suspended, or the packaging bottles that need to be loaded are kept at a long interval, resulting in too long an interval time required for filling, which greatly reduces the filling efficiency.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the rotary filling head design, during the filling and feeding process, the filling head moves downward and inserts into the packaging bottle for filling. During the filling process, it will move synchronously with the packaging bottle and perform filling during the movement, without pausing the feeding and conveying of the packaging bottle. After filling is completed, the filling head directly moves upward and withdraws, thus fully ensuring the filling efficiency and achieving continuous and uninterrupted filling.

[0020] 2. Visual observation components are arranged at the loading and unloading ports of the conveyor. When loading, the internal state of the packaging bottle before filling is collected by an industrial camera and compared with the standard state. When unloading, the state after filling is collected and compared. Coupled with the weighing structure at the loading and unloading ports, it can further ensure the accuracy of the filling volume and is also convenient for monitoring the sanitary condition.

[0021] 3. The stirring rod of the synchronous belt of the driving motor rotates when the rotary belt runs, which can stir the food powder to be filled, avoid the powder inside from caking, and can maintain effective and continuous feeding, thus avoiding insufficient filling volume caused by insufficient feeding and ensuring the stability of the quantitative filling device during operation.

[0022] 4. Through the adjustable limit side plates on both sides, when loading the packaging bottle, the distance between the two limit side plates can be adjusted according to the width of the packaging bottle, so that when the packaging bottle slides, both sides can be very close to the limit side plates, which is convenient for aligning the packaging bottle mouth with the filling head outlet during filling and improves the applicable range of the filling device.

[0023] 5. During filling, the filling head cooperates with the cover plate on its outer ring, the feeding track belt and the support plate to tightly press the packaging bottle, avoiding the shaking of the packaging bottle and ensuring the filling accuracy. At the same time, the vibration knocking plate at the bottom knocks the support plate intermittently, and the vibration force acts on the packaging bottle through the support plate, so that the contents in the packaging bottle can quickly vibrate to the bottom, and it also avoids more residual gas inside the powder during filling, which affects the accumulation.

The output end of the lifting cylinder 28 passes through the fixed side plate 27 and is fixed on the top surface of the filling head 3. The filling head 3 is provided with an air inlet 17 and a feed port 18. Each feed port 18 is connected to a guide pipe 20 through a rotary joint 19. The length of each guide pipe 20 is greater than the distance from the connecting branch pipe 21 to the edge of the conduit bracket 33 and then to the feed port 18. The end of the guide pipe 20 away from the filling head 3 is connected to the connecting branch pipe 21 through the rotary joint 19. All the connecting branch pipes 21 are connected to the bottom surface of the main material pipe 8.

[0038] Limiting components are arranged on both sides of the top surface of the conveyor 4 .

[0039] As a further embodiment of the present invention, camera brackets 5 are fixed to the top surfaces of the conveyors 4 at both ends of the filling machine 1, and loading industrial cameras 6 and unloading industrial cameras 7 are respectively arranged on the bottom surfaces of the top ends of the two camera brackets 5. The internal transmission direction of the conveyor 4 is from the loading industrial camera 6 to the side of the unloading industrial camera 7. A gravity sensor is arranged in the conveyor 4 below the loading industrial camera 6 and the unloading industrial camera 7. The running transmission speed of the conveyor 4 is the same as the running transmission speed of the rotary crawler 11. The camera bracket 5 is arranged in an inverted "U" shape. When loading, the loading industrial camera 6 collects the internal state of the packaging bottle before filling through the bottle mouth, and compares it with the standard state to determine whether the interior is clean and tidy. When unloading, the unloading industrial camera 7 collects the state after filling through the bottle mouth, and compares it with the standard state after filling. When passing through the loading industrial camera 6 and the unloading industrial camera 7, the packaging bottle before and after filling is weighed, and the difference between the two can display the weight of quantitative filling.

[0040] As a further embodiment of the present invention, a stirring rod is rotatably connected to the filling barrel 2 through a bearing, and one end of the stirring rod extending to the outside of the bottom surface of the filling barrel 2 is transmission-connected to a transmission belt 3 32, and the other end of the transmission belt 32 is transmission-connected to a transmission shaft 31, and the transmission shaft 31 is transmission-connected to a rotating rod on the bottom surface of the transmission wheel 12 below the drive motor 13 through a transmission belt 2 30. A groove cooperating with the transmission belt 2 30 is provided on the rear side of the support frame 9. When loading, the stirring rod inside the filling barrel 2 stirs the food powder inside to avoid unsmooth loading of the food raw materials stored in the filling barrel 2 due to agglomeration.

The surface of the catheter bracket 33 is raised, so that each guide pipe 20 will be bumped when passing through each protrusion. When bumping, the sliding of the powder inside the guide pipe 20 can be accelerated, so that the guide pipe 20 can be better kept unobstructed.

[0042] As a further embodiment of the present invention, a through hole cooperating with the connecting branch 21 is opened on the top surface of the rotating bracket 10, and a photoelectric sensor 15 is arranged at one end of the front side of the rotating bracket 10 close to the loading industrial camera 6, and a photoelectric sensor 2 16 is arranged at one end of the front side of the rotating bracket 10 close to the unloading industrial camera 7. The output ends of the photoelectric sensor 15 and the photoelectric sensor 2 16 are both electrically connected to the input end of the lifting cylinder 28. When the filling head 3 moves to the position of the photoelectric sensor 15, the lifting cylinder 28 pushes the photoelectric sensor 15 to move downward, inserts into the bottle mouth of the packaging bottle and moves with the packaging bottle, and filling is performed during the movement. When the filling head 3 moves to the position of the photoelectric sensor 2 16, the lifting cylinder 28 drives the filling head 3 to move upward to separate from the packaging bottle, and the filling is completed.

[0043] As a further embodiment of the present invention, the limiting assembly includes a limiting side plate 29, a moving rod 34, a support column 35, a positioning ball 22 and a fixing screw 26.

[0044] As a further embodiment of the present invention, the height of the limiting side plate 29 is less than the height of the packaging bottle, and each support column 35 and the positioning ball 22 are provided with a sliding groove that cooperates with the moving rod 34, and the support column 35 on the top surface of the sliding groove is provided with a thread that cooperates with the fixing screw 26, and the two limiting side plates 29 are both perpendicular to the top surface of the conveyor 4.

[0045] As a further embodiment of the present invention, a feeding track 36 is provided inside the transmission machine 4. A support plate 37 is provided between the upper and lower feeding tracks 36 below the support frame 9, and the rear side of the support plate 37 is fixed to the side wall of the filling machine 1. A sliding intermediate plate 38 is slidably provided on the top of the support plate 37, and limiting sliders 39 are symmetrically fixed to the bottom surface of the sliding intermediate plate 38. The two limiting sliders 39 are slidably connected to the inside of the support plate 37. Sliding grooves matching the limiting sliders 39 are symmetrically formed inside the support plate 37. The limiting sliders 39 are arranged in an inverted "T" shape. A vibrating knocking plate 40 is provided on the side of the sliding intermediate plate 38. The contact surfaces of the sliding intermediate plate 38 and the vibrating knocking plate 40 are arranged in a mutually matching "丿" shaped inclined state. Moving plates 41 are symmetrically fixed to the side of the vibrating knocking plate 40 away from the sliding intermediate plate 38. An fixing plate 42 is provided between the two moving plates 41, and the rear end of the fixing plate 42 is fixed to the side wall of the filling machine 1. A number of sliding rods 43 are slidably sleeved inside the fixing plate 42, and the upper and lower ends of the sliding rods 43 are fixed to the side walls of the moving plates 41. Springs 44 are slidably sleeved on each of the sliding rods 43 at the bottom of the fixing plate 42, and the upper and lower ends of the springs 44 are respectively fixed to the fixing plate 42 and the moving plates 41. A push plate 45 is provided on the side of the sliding intermediate plate 38 away from the vibrating knocking plate 40. The push plate 45 is oval-shaped. The height difference between the height and the length of the push plate 45 is equal to the distance between the vibrating knocking plate 40 and the shock pad 47. The push plate 45 is rotatably connected to the support plate 37 through a bearing. The rear end of the push plate 45 is drivingly connected to the output shaft of the motor of the transmission machine 4 through a transmission belt 46.

[0046] Working principle of the present invention: when in use, first adjust the distance between the two limiting side plates 29 according to the width of the packaging bottle. When adjusting, turn the fixing screw 26 so that the fixing screw 26 moves up to release the pressing and fixing of the moving rod 34, then pull the limiting side plate 29 so that the limiting side plate 29 is 1-5mm away from the packaging bottle, and then turn the fixing screw 26 so that the fixing screw 26 presses and fixes the moving rod 34 again. Place the packaging bottles at the interval between the two filling heads 3. Before starting the filling device, align the first filling bottle to be loaded with the filling head 3 close to the loading industrial camera 6. Before alignment, open the conveyor 4 first to allow the packaged product to pass through the loading industrial camera 6. At this time, the loading industrial camera 6 collects the internal image of the packaging bottle through the bottle mouth, and loads the bottle at the same time. The gravity sensor under the industrial camera 6 detects the weight of the packaging bottle. After the detection, it passes through the loading industrial camera 6 and is aligned with the filling head 3. After alignment, the filling machine 1 is turned on to make the filling machine 1 run to transport the powder in the filling barrel 2 to the main material pipe 8, and under the guidance of the connecting branch pipe 21, it is dispersed into the guide pipe 20 and reaches the filling head 3 through the rotating joint 19 and the feed port 18. At the same time, the driving motor 13 runs to drive the rotating crawler 11 to move. The rotating crawler 11 has the same moving speed as the conveyor 4 when running, so that the filling head 3 is always located above the packaged product. When the filling head 3 moves to the position of the photoelectric sensor 15, the lifting cylinder 28 runs to push the filling head 3 down. After the filling head 3 moves down to the inside of the packaging bottle, filling can be carried out. When the filling head 3 moves to the position of the photoelectric sensor 16, the filling is completed, and the lifting cylinder 28 drives the filling head 3 to move up. At this time, the filling head 3 rotates under the rotating crawler 11. When the filling head 3 moves, it drives the guide tube 20 to slide on the guide tube bracket 33. Every time it encounters a protrusion, the powder inside the guide tube 20 will slide down quickly due to the bump. At this time, the filled packaging bottle enters the packaging line after the image is collected by the unloading industrial camera 7. At the same time, the gravity sensor under the unloading industrial camera 7 detects the weight of the filled packaging bottle. When the driving motor 13 is running, it drives the transmission belt 2 30 to move through the rotating rod. When the transmission belt 2 30 moves, it drives the transmission shaft 31 to rotate, and the stirring rod inside the filling barrel 2 can be driven by the transmission belt 3 32. The filling head 3 moves downward and drives the cover plate of its outer ring to move downward. With the cooperation of the support plate 37, the feeding crawler 36 and the cover plate cooperate to press the packaging bottle tightly and drive the packaging bottle to move along with the feeding crawler 36. When the conveyor 4 is running, its driving motor 13 drives the push plate 45 to rotate through the transmission belt 46. When the push plate 45 rotates, it intermittently pushes the sliding intermediate plate 38, so that the sliding intermediate plate 38 pushes the vibration knocking plate 40 to move upward. When moving, it drives the moving plate 41 to compress the spring 44, and at the same time, the vibration knocking plate 40 knocks the support plate 37. The vibration force acts on the packaging bottle through the support plate 37, so that the powder can quickly fall to the bottom of the packaging bottle. When the push plate 45 rotates to be placed vertically,The vibration knocking plate 40 moves downward and resets under the push of the spring 44, thereby forming a continuous reciprocating knocking vibration.
