[0021] 1. Through the feeding device, fixing component, supporting component and feeding component provided by the present invention, first, the material is poured into the belt connecting pipe through the feeding pipe, and then the servo motor is started. The servo motor drives the driving bevel gear to rotate. While the driving bevel gear rotates, it drives the driven bevel gear and the auger fixed at one end of the driven bevel gear to rotate, so that the material falls into the feeding pipe. Then, by rotating the adjusting ring, when the adjusting ring rotates, it drives the connecting rod to move through the groove formed on itself and the adjusting hole formed on the movable ring. When the connecting rod moves, it drives the supporting bracket arranged on the connecting rod to expand around, so as to open and fix the ton bag opening. Finally, operate the driving plate. At this time, the driving plate will drive the movable ring to rotate. While the movable ring rotates, it drives the guide rod to move along the inner wall of the guide hole through the guide hole formed on the movable plate, and drives the triangular adjusting plate to move along the chute formed on the fixed plate through the sliding block, so as to adjust the discharge amount of the feeding pipe or completely close the feeding pipe. This device reduces the situation that the material deviates to one side when entering the ton bag, reduces the uneven quality of the material entering the ton bag, improves the consistency and stability of the packaged product, avoids the waste of the material, and improves the packaging speed and accuracy.

[0022] 2. Through the supporting component provided by the present invention, first, by rotating the adjusting ring, when the adjusting ring rotates, it drives the connecting rod to move through the groove formed on itself and the adjusting hole formed on the movable ring.

[0035] Example 1

[0036] In the specific implementation process, as Figures 1 to 8As shown in the figure, a conveyor belt 23 is fixedly connected to the bottom of the frame through a fixing frame. A support plate 3 is fixedly connected to the top of the body 1. A blanking device is arranged on the inner wall of the through hole opened on the support plate 3. The elevator 2 is fixedly connected to one side wall of the frame. The blanking device includes a blanking pipe 4, a movable plate 5, a fixing component, and a blanking hose 6. The blanking pipe 4 is arranged on the inner wall of the groove opened on the support plate 3, and a feeding component is fixedly connected to the top of the blanking pipe 4. The inner wall of the through hole opened on the top of the movable plate 5 is rotatably connected to one end of the blanking pipe 4 away from the support plate 3, and a number of guiding holes 7 are opened on the movable plate 5. A driving plate 8 is fixedly connected to one side wall of the movable plate 5. The fixing component is rotatably connected to the inner wall of the groove opened on the movable plate 5. One end of the blanking hose 6 is fixedly connected to one end of the fixing component away from the movable plate 5, and a supporting component is rotatably connected to the end of the blanking hose 6 away from the fixing component;

[0037] It should be noted that the blanking pipe 4 serves as the conveying channel for the material from the feeding component to the ton bag. The blanking pipe 4 ensures that the material can flow orderly and smoothly, and the blanking pipe 4 plays a transitional role in connecting the feeding component and the subsequent packaging link in the whole packaging system;

[0038] The fixing component includes a fixing plate 9 and a number of triangular adjusting plates 10. The fixing plate 9 is rotatably connected to the inner wall of the groove opened on the movable plate 5. The number of triangular adjusting plates 10 are slidably connected to the inner wall of the chute opened on the top of the fixing plate 9 through sliding blocks, and a guiding rod 11 is fixedly connected to the top of the number of triangular adjusting plates 10. The guiding rod 11 is movably connected to the inner wall of the guiding hole 7 opened on the movable plate 5;

[0039] It should be noted that the size of the guiding rod 11 matches the size of the guiding hole 7 opened on the movable plate 5 to ensure the precise adjustment of the position of the blanking device. When adjusting the position of the blanking hose 6 by sliding the triangular adjusting plate 10 in the fixing component, the guiding rod 11 slides in the guiding hole 7. The matching size enables the guiding rod 11 to move smoothly in the guiding hole 7 without shaking or deviation, so as to accurately guide the blanking hose 6 to the appropriate position of the ton bag inlet, ensure that the material is accurately filled into the ton bag, and improve the packaging accuracy;

[0040] During use, first operate the driving plate 8. At this time, the driving plate 8 will drive the movable ring to rotate. While the movable ring is rotating, it will drive the guiding rod 11 to move along the inner wall of the guiding hole 7 through the guiding hole 7 opened on the movable plate 5, and drive the triangular adjusting plate 10 to move along the chute opened on the fixing plate 9 through the sliding block, so as to adjust the discharge amount of the blanking pipe 4 or completely close the blanking pipe 4;

[0041] The support assembly includes an adjusting ring 12, a fixing ring 13 and a plurality of support brackets 14. The adjusting ring 12 is rotatably connected to the inner wall of the groove formed at one end of the blanking hose 6 away from the fixing assembly. The fixing ring 13 is rotatably connected to the inner wall of the groove formed at the bottom of the adjusting ring 12. And a plurality of adjusting holes are formed at one end of the fixing ring 13 away from the adjusting ring 12. A plurality of connecting rods 15 are respectively rotatably connected to the inner walls of the plurality of adjusting holes. The plurality of connecting rods 15 are all movably connected to the inner wall of the groove formed at one end of the adjusting ring 12 away from the blanking hose 6. The plurality of support brackets 14 are respectively fixedly connected to one ends of the plurality of connecting rods 15 away from the adjusting ring 12;

[0042] It should be noted that a plurality of rubber soft blocks 24 are respectively fixedly connected to one side side walls of the plurality of support brackets 14. The surface of the rubber soft blocks 24 has a certain roughness, which can increase the friction force with the inner wall of the ton bag. This enables the support brackets 14 to more stably fix the ton bag at the current position after opening the feeding port of the ton bag, preventing the ton bag from sliding or shifting during the material filling process, ensuring that the material is accurately filled into the ton bag, improving the packaging efficiency and quality. The plurality of rubber soft blocks 24 are made of natural rubber material. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grass. Natural rubber has high elasticity, good mechanical strength, good flexibility, excellent airtightness and good processing performance;

[0043] During use, first, by rotating the adjusting ring 12, when the adjusting ring 12 rotates, it will drive the connecting rod 15 to move through the groove formed on itself and the adjusting holes formed on the movable ring. When the connecting rod 15 moves, it drives the support brackets 14 provided on the connecting rod 15 to expand around, so as to open and fix the ton bag opening;

[0044] The feeding assembly includes a connecting pipe 16, a feeding pipe 17, a driving member and a driving bevel gear 18. The connecting pipe 16 is fixedly connected to the top of the blanking pipe 4. The feeding pipe 17 is fixedly connected to the inner wall of the through hole formed at the top of the connecting pipe 16. And a cover plate 22 is hinged to the top of the feeding pipe 17 through a hinge. The driving member is fixedly connected to one end of the connecting pipe 16. And the output end of the driving member is fixedly connected to one end of the driving bevel gear 18. A driven bevel gear 19 is engaged with one side side wall of the driving bevel gear 18. A screw conveyor 20 is fixedly connected to one end of the driven bevel gear 19 away from the driving bevel gear 18;

[0045] It should be noted that the driving member is a servo motor 21. The servo motor 21 is fixedly connected to one end of the connecting pipe 16, and the output end of the servo motor 21 is fixedly connected to one end of the driving bevel gear 18. And through the provided cover plate 22, during the material conveying process, the cover plate 22 can effectively prevent the material in the feeding pipe 17 from spilling out due to external factors (such as vibration, air flow, etc.), keeping the working environment clean. And if the packaged material has a special smell, the cover plate 22 can, to a certain extent, block the odor from spreading into the surrounding environment, improve the air quality of the workplace, protect the health of the operators, and create a relatively comfortable working environment;

[0046] During use, first pour the material into the connecting pipe 16 through the feeding pipe 17, and then start the servo motor 21. The servo motor 21 drives the driving bevel gear 18 to rotate. While the driving bevel gear 18 is rotating, it drives the driven bevel gear 19 and the auger 20 fixed to one end of the driven bevel gear 19 to rotate, so that the material falls into the blanking pipe 4.
