[0034] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0035] Example 1:

[0036] This embodiment provides a ton charter aircraft, such as Figure 1 As shown, the machine comprises a frame 26 and a liftable conveyor 27. The frame 26 includes a work platform 28 and legs 29. The top of the legs 29 is connected to the work platform 28. The conveyor 27 is located below the work platform 28. A packaging scale 30 is mounted on the legs 29. The packaging scale 30 is equipped with a weighing plate 31 for transferring the weight of the ton bag to the packaging scale 30. A feeding mechanism is provided on the work platform 28. The packaging scale 30 can also use a weight sensor.

[0037] The working platform 28 is used to install the feeding mechanism, and the ton bag is located under the working platform 28 to receive the material; the liftable conveying device 27 can lift the ton bag so that the ton bag does not come into contact with the packaging scale 30 during transportation, and the packaging scale 30 will not be subjected to lateral impact, thereby ensuring the weighing accuracy of the packaging scale 30 and extending the service life of the packaging scale 30; the packaging scale 30 is connected to the support leg 29, which only weighs the ton bag and can ensure the accuracy of the weighing data; the weighing platform 31 is used to place the ton bag, so that the weight of the ton bag is transferred to the packaging scale 30 after the conveying device 27 is lowered, so as to weigh the ton bag.

[0038] To ensure reliable weighing, the packaging scale 30 is U-shaped, with both ends of the U-shaped opening connected to the legs 29, and both ends of the U-shaped bottom edge of the packaging scale 30 connected to the legs 29. The U-shaped design of the packaging scale 30 provides a wide coverage area, ensuring a secure fit between the weighing platform 31 and the packaging scale 30, thereby facilitating weighing. The four corners of the packaging scale 30 are all connected to the legs 29, ensuring reliable fixation of the packaging scale 30, reducing shaking and tilting, and ensuring more accurate weighing.

[0039] In order to ensure reliable delivery, Figure 2 As shown, the conveying device 27 includes a movable conveying trolley 32 equipped with a first lifting mechanism 33. The lifting end of the first lifting mechanism 33 engages with the scale plate 31. In the weighing state, the scale plate 31 engages with the packaging scale 30. In the transport state, a gap exists between the scale plate 31 and the packaging scale 30. The movable conveying trolley 32 facilitates the movement of the trolley 32 carrying the ton-sized bag between workstations, reducing the workload of workers. The first lifting mechanism 33 ensures that the scale plate 31 is raised, ensuring that the ton-sized bag is transported without impacting the packaging scale 30, thereby ensuring the operating accuracy of the packaging scale 30. In this embodiment, the first lifting mechanism 33 can be a hydraulic lifting device, such as a hydraulic cylinder.

[0040] In this embodiment, the weighing platform 31 is rectangular, and downward-folded edges 38 are provided on both sides of the weighing platform 31. The folded edges 38 can prevent the weighing platform 31 from slipping during the movement of the conveying trolley 32. When the weighing platform 31 slides to the edge, it will abut against the telescopic end of the first lifting mechanism 33.

[0041] In order to ensure reliable movement of the transport trolley 32, the transport device 27 includes a track 34. The bottom of the transport trolley 32 is provided with a running wheel 35. The running wheel 35 cooperates with the track 34 to ensure that the movement path of the transport trolley 32 is stable and reliable.

[0042] In this embodiment, a rotating motor is provided on the transport trolley 32 , and the rotating motor drives the running wheels 35 to rotate so that the transport trolley 32 can travel along the track 34 .

[0043] To ensure reliable degassing of materials in the ton bag, a first vibration motor 39 is provided on the weighing plate 31. The first vibration motor 39 is used to degas materials in the ton bag through vibration. The first vibration motor 39 is located on the bottom surface of the weighing plate 31, so that the impact of vibration on the first lifting mechanism 33 is minimized, thereby ensuring the service life of the first lifting mechanism 33. At the same time, the first vibration motor 39 acts as a barrier to prevent the weighing plate 31 from sliding during the movement of the conveyor trolley 32.

[0044] In order to ensure reliable feeding, Figure 3 、 Figure 4 、 Figure 5As shown, the feeding mechanism includes a feed bin 1 and a discharge bin 2, and a first feeding sleeve 3 and a second feeding sleeve 4 are provided between the feed bin 1 and the discharge bin 2. The two ends of the first feeding sleeve 3 are respectively connected to the feed bin 1 and the discharge bin 2, and the two ends of the second feeding sleeve 4 are respectively connected to the feed bin 1 and the discharge bin 2. A first screw feeder 5 is provided in the first feeding sleeve 3, and a second screw feeder 6 is provided in the second feeding sleeve 4. A feed port 7 is provided on the feed bin 1, and a discharge port 8 is provided on the discharge bin 2; a driving assembly 9 is also included, and the driving assembly 9 is used to drive the first screw feeder 5 and the second screw feeder 6. In this embodiment, the feed port 7 is located at the top of the feed bin 1, and the discharge port 8 is located at the bottom of the discharge bin 2; the two sides of the feed bin 1 are inclined toward the first screw feeder 5 and the second screw feeder 6, so as to facilitate the concentration of materials toward the first screw feeder 5 and the second screw feeder 6, and the bottom surface of the discharge bin 2 is inclined relative to the side surface of the discharge bin 2, so as to facilitate the movement of materials toward the discharge port 8. The design of the first feeding sleeve 3 and the second feeding sleeve 4 realizes a dual channel for material transportation, with a higher feeding rate, and even if one side is blocked or damaged, the other side can still feed, which is more reliable. The first spiral feeder 5 and the second spiral feeder 6 are used to transport materials. The feed bin 1 is used to concentrate the materials, which is convenient for material transportation, and only needs to be fed inward from the feed port 7, without the need to place the first feeding sleeve 3 and the second feeding sleeve 4 separately. In order to facilitate the control of the feed amount, the diameter of the first feeding sleeve 3 is larger than the diameter of the second feeding sleeve 4. The diameter of the first feeding sleeve 3 is large, and it can accommodate more powder for transmission, which is suitable for fast feeding. The diameter of the second feeding sleeve 4 is small, and it can accommodate relatively less powder for transmission, which is suitable for high-precision feeding. The diameter of the first spiral blade 11 is larger than the diameter of the second spiral blade 14. The first spiral blade 11 can be used for fast feeding close to the target value, and the second spiral blade 14 is used for high-precision feeding when close to the target value, so that the weight deviation is smaller.

[0045] In order to ensure the reliability of the first spiral feeder 5, the first spiral feeder 5 includes a first rotating shaft 10 and a first spiral blade 11, and the first spiral blade 11 is arranged on the first rotating shaft 10; the feed bin 1 or the discharge bin 2 or the first feeding sleeve 3 is rotatably connected to the first rotating shaft 10; the spiral of the first spiral blade 11 is an unequal-pitch spiral. The unequal-pitch design realizes mutual extrusion between materials through the change of volume during the spiral feeding process to achieve exhaust, thereby solving the problem of insufficient filling of materials with lower density. In this embodiment; the pitch of the first spiral blade 11 near the feed bin 1 side is large, and the pitch near the discharge bin 2 side is small, and the pitch of the first spiral blade 11 decreases step by step, that is, the space between the two adjacent first spiral blades 11 near the feed bin 1 side is large, and more materials can be driven, and the space between the two adjacent first spiral blades 11 near the discharge bin 2 side is small, so that the materials are squeezed and exhausted.

[0046] In order to ensure reliable feeding, part of the first spiral blade 11 is located in the feed bin 1, which can ensure that the material in the feed bin 1 can be driven and transported by the first spiral blade 11; a third spiral blade 12 is provided on the first rotating shaft 10, and the spiral direction of the third spiral blade 12 is opposite to the spiral direction of the first spiral blade 11. The third spiral blade 12 is located in the discharge bin 2. The design of the third spiral blade 12 can play a reverse conveying role, so that the material sent by the first spiral blade 11 contacts the third spiral blade 12, which plays a role of squeezing and exhausting, and is located in the discharge bin 2, which can prevent the material from continuing to be transported forward, so that the material can be discharged from the discharge port 8 after falling from the first rotating shaft 10.

[0047] In order to ensure the reliability of the second spiral feeder 6, the second spiral feeder 6 includes a second rotating shaft 13 and a second spiral blade 14, and the second spiral blade 14 is arranged on the second rotating shaft 13; the feed bin 1 or the discharge bin 2 or the second feeding sleeve 4 is rotatably connected to the second rotating shaft 13; the spiral of the second spiral blade 14 is an unequal-pitch spiral. The unequal-pitch design realizes the mutual extrusion between materials through the change of volume during the spiral feeding process to achieve exhaust, thereby solving the problem of insufficient filling of materials with lower density. In this embodiment, the pitch of the second spiral blade 14 is large near the side of the feed bin 1, and the pitch is small near the side of the discharge bin 2, and the pitch of the second spiral blade 14 decreases step by step, that is, the space between the two adjacent second spiral blades 14 near the side of the feed bin 1 is large, and more materials can be driven, and the space between the two adjacent second spiral blades 14 near the side of the discharge bin 2 is small, so that the materials are squeezed and exhausted.

[0048] In order to ensure reliable feeding, part of the second spiral blade 14 is located in the feed bin 1, which can ensure that the material in the feed bin 1 can be driven and transported by the second spiral blade 14; a fourth spiral blade 15 is provided on the second rotating shaft 13, and the spiral direction of the fourth spiral blade 15 is opposite to the spiral direction of the second spiral blade 14. The fourth spiral blade 15 is located in the discharge bin 2. The design of the fourth spiral blade 15 can play a role in reverse conveying, so that the material sent by the second spiral blade 14 contacts the fourth spiral blade 15, which plays a role in squeezing and exhausting. It is located in the discharge bin 2, which can prevent the material from continuing to be transported forward, so that the material can be discharged from the discharge port 8 after falling from the second rotating shaft 13.

[0049] In order to ensure reliable rotation, Figure 6As shown, two connecting shaft assemblies 16 are provided on the side of the discharge bin 2 away from the feed bin 1. The connecting shaft assembly 16 includes a sleeve 17, a connecting shaft 18, and a bearing 19. The sleeve 17 is connected to the discharge bin 2. The connecting shaft 18 is inserted into the sleeve 17 and rotatably connected to the sleeve 17 via the bearing 19. One connecting shaft 18 is connected to the first rotating shaft 10, and the other connecting shaft 18 is connected to the second rotating shaft 13. A sealing sleeve 20 is provided between the sleeve 17 and the connecting shaft 18. The sealing sleeve 20 is located between the bearing 19 and the feed bin 1 to prevent material dust from entering and affecting the bearing 19, ensuring smooth rotation. The first rotating shaft 10 and the second rotating shaft 13 are rotatably connected to the discharge bin 2 via the connecting shaft assembly 16.

[0050] To ensure reliable feeding, a star-shaped discharger 21 is installed above the feed bin 1 and connected to the feed port 7, ensuring more stable material entry. A filter 22 is installed on the discharge bin 2 and communicates with the interior of the discharge bin 2 to balance air pressure and prevent material dust from entering the outside. A control valve 25 is installed on the discharge port 8 to control the opening and closing of the discharge port 8. In this embodiment, the feeding mechanism and frame 26 are separate units. The feeding mechanism is hoisted via a flange, so the weight of the feeding mechanism is not transferred to the frame 26, ensuring accurate weighing.

[0051] In order to ensure reliable driving, the drive assembly 9 includes a first drive member 23 and a second drive member 24. The first drive member 23 is used to drive the first screw feeder 5, and the second drive member 24 is used to drive the second screw feeder 6. The first screw feeder 5 and the second screw feeder 6 can be controlled separately. Specifically, the output end of the first drive member 23 is connected to one end of the first rotating shaft 10, and the output end of the first drive member 23 is connected to one end of the second rotating shaft 13. The first drive member 23 is located on the side of the feed bin 1 away from the discharge bin 2, and the second drive member 24 is located on the side of the feed bin 1 away from the discharge bin 2. The first drive member 23 and the second drive member 24 are both connected to the feed bin 1; in this embodiment, the first drive member 23 and the second drive member 24 both use reduction motors, and the discharge bin 2 is used for centralized discharge.

[0052] like Figure 10As shown, the discharge port 8 is provided with a discharge pipe 43 extending downward, and the two sides of the control valve 25 are respectively connected to the discharge pipe 43 and the discharge port 8. The discharge pipe 43 is provided with a first discharge cover 44, which is sleeved on the outside of the discharge pipe 43, and the top of the first discharge cover 44 is connected to the outer wall of the discharge pipe 43; the working platform 28 is provided with a second discharge cover 45, which is located between the first discharge cover 44 and the discharge pipe 43, and the top of the second discharge cover 45 is higher than the top surface of the working platform 28; the bottom surface of the first discharge cover 44 is lower than the top surface of the second discharge cover 45. The design of the discharge pipe 43 makes discharge more convenient. The first discharge cover 44 prevents dust from escaping from the part above the working platform 28; the second discharge cover 45 prevents dust from escaping from the part below the working platform 28. The multi-layer design of the discharge pipe 43, the first discharge cover 44 and the second discharge cover 45 allows the feeding mechanism and the working platform 28 to be completely separated. The packaging scale 30 will not weigh the weight of the feeding mechanism, which means that the material that has not yet entered the ton bag will not be weighed, and the weighing is more accurate.

[0053] The packaging bag hook 42 is also included. One end of the packaging bag hook 42 is connected to the support leg 29. The dust removal mechanism is used to extract dust that escapes during the packaging process. The dust removal mechanism is typically a dust removal duct connected to an external negative pressure system. This is prior art and will not be described in detail herein. In this embodiment, the dust removal mechanism includes a first dust removal duct 46 and a second dust removal duct 47. The inlet of the first dust removal duct 46 is located between the discharge pipe 43 and the first discharge cover 44, and the inlet of the second dust removal duct 47 is located between the discharge pipe 43 and the second discharge cover 45.

[0054] The system also includes a controller, to which the conveyor device 27, packaging scale 30, first vibrating motor 39, first drive member 23, and second drive member 24 are all electrically connected. The controller provides coordinated control, ensuring that the feeding speeds of the first and second drive members 23, 24 are coordinated in real time with the packaging scale 30, achieving high-precision feeding and a high degree of overall automation.

[0055] During the packaging process, the packaging scale 30 detects that the weight has reached the set value, and the first lifting mechanism 33 drives the weighing plate 31 to rise, so that the ton bag is separated from the packaging scale 30, and then the first vibration motor 39 is started for vibration degassing. After the degassing is completed, the first lifting mechanism 33 drives the weighing plate 31 to descend, and the packaging scale 30 re-weighs the ton bag, so that the packaging accuracy is higher.

[0056] Example 2:

[0057] This embodiment provides a ton charter aircraft, such as Figure 7 、 Figure 8 、 Figure 9As shown, the conveying device 27 in this embodiment is different from the conveying device 27 in Example 1, but the remaining technical features are the same as those described in Example 1. The conveying device 27 includes a conveyor roller 36 and a second lifting mechanism 37. The lifting end of the second lifting mechanism 37 is connected to the conveyor roller 36, and the second lifting mechanism 37 is used to lift the conveyor roller 36. The second lifting mechanism 37 lifts the conveyor roller 36, which also causes the conveyor roller 36 to lift the ton bag. At this time, the ton bag does not contact the packaging scale 30. When the ton bag is conveyed, the packaging scale 30 is not subjected to lateral impact, thereby ensuring the weighing accuracy of the packaging scale 30 and extending the service life of the packaging scale 30.

[0058] To ensure reliable transport of ton bags, the conveyor roller conveyor 36 comprises multiple coplanar rollers. A weighing platform 31 is positioned between adjacent rollers, with both sides of the platform connected to the packaging scale 30. A mounting plate 40 is located beneath the platform 31, with the rollers rotatably connected to it. The lifting end of the second lifting mechanism 37 is connected to the mounting plate 40. A second vibration motor 41 is mounted on the mounting plate 40 and electrically connected to the controller. In this embodiment, the platform 31 and the packaging scale 30 are integrally formed. The conveyor roller conveyor 36 is equipped with a rotating motor, whose output shaft drives the multiple rollers via a chain and sprocket assembly, thereby conveying the ton bags. The positioning of the platform 31 between adjacent rollers allows for a wide range of placement, facilitating the placement of ton bags and providing excellent support for the bags, enabling more accurate weighing on the packaging scale 30. Furthermore, the lifting and lowering of the rollers does not interfere with the platform 31.

[0059] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
