They are usually made of polyester fiber materials such as polypropylene and polyethylene, and processed with woven cloth or composite materials. Ton bags are generally equipped with lifting ears or other devices on the top to facilitate lifting.

The air pump pumps air into the feeding pipe through the electric three-way valve and the air inflation pipe, thereby expanding the ton bag, and then the feeding pipe injects materials into the ton bag. After stopping injecting materials into the ton bag, when the ton bag is injected with materials, the worker starts the pipe pushing cylinder through the control system. The piston rod of the pipe pushing cylinder pushes the middle pipe down until the circumferential outer wall of the middle pipe is tightly against the circumferential inner wall of the feeding pipe. At this time, the middle pipe drives the stirring ring to approach the piled materials in the ton bag, and then the rotating part drives the stirring ring to rotate, and the material spreading arc plate on the stirring ring unfolds, and as the stirring ring rotates, the piled materials are flattened, thereby flattening the materials accumulated at the filling port of the ton bag, thereby reducing the occurrence of materials being sealed outside the ton bag when sealing the bag, which is beneficial to improving the accuracy of the material quality in the ton bag.

[0010] By adopting the above technical solution, when dust materials are injected into the ton bag through the feeding pipe, the air pressure in the ton bag increases, and the worker starts the exhaust fan through the control system. The exhaust fan draws out the air in the ton bag through the dust exhaust pipe, and the dust in the air is isolated in the ton bag by the annular screen, thereby reducing the increased air pressure in the ton bag and reducing the possibility of dust materials diffusing into the air.
[0011] Optionally, the rotating part includes an anti-slip ring coaxially arranged at the end of the intermediate tube, the stirring ring is rotatably arranged on the anti-slip ring, the stirring ring is coaxially provided with an annular air groove at one end facing the intermediate tube, an air supply pipe is provided on the intermediate tube along the direction from the intermediate tube to the stirring ring, the air supply pipe passes through the anti-slip ring and is communicated with the annular air groove, the interior of the material laying arc plate is hollow, and a rotating shaft tube is coaxially rotatably arranged at the rotation center of the material laying arc plate, one end of the rotating shaft tube is communicated with the annular air groove, and the other end is connected with the interior of the material laying arc plate, an exhaust hole is provided on the material laying arc plate on one side facing the side wall of the receiving groove, a return compression spring is supported between the material laying arc plate and the receiving groove, and the return compression spring is used to press the material laying arc plate tightly against the receiving groove.
[0012] By adopting the above technical scheme, when the circumferential outer wall of the intermediate tube is pressed against the circumferential inner wall of the feeding tube, the worker starts the air pump and the electric three-way valve through the control system. The air pump pumps air into the cavity surrounded by the feeding tube, the inner tube and the intermediate tube through the electric three-way valve and the air blowing pipe. The air flows into the annular air groove through the air supply pipe, and then flows into the cavity of the paving arc plate through the rotating shaft tube, and is discharged from the exhaust holes on the paving arc plate. The reaction force of the high-pressure air discharged from the exhaust holes blowing to the receiving groove pushes the paving arc plate to expand, and the reset compression spring is squeezed and deformed by the paving arc plate. The axis of the exhaust hole on the expanded paving arc plate is inclined relative to the axis of the stirring ring, so that the stirring ring rotates around the axis of the anti-slip ring. At the same time, the stirring ring drives the paving arc plate to rotate, so as to flatten the piled materials.
[0013] Optionally, when the stirring ring rotates, one end of the material spreading arc plate is located inside the stirring ring, and the other end is located outside the stirring ring, and the length of the material spreading arc plate outside the stirring ring is longer than the length of the material spreading arc plate inside the stirring ring.
[0014] By adopting the above technical solution, when the stirring ring rotates, since the length of the spreading arc plate outside the stirring ring is longer than the length of the spreading arc plate inside the stirring ring, more exhaust holes can be opened on the spreading arc plate outside the stirring ring, thereby making it easier to unfold the spreading arc plate. When the stirring ring rotates, the spreading arc plate outside the stirring ring can provide greater centrifugal force, thereby making the rotation of the spreading arc plate have a better spreading effect.
[0015] Optionally, a plurality of blowing holes are provided on the material laying arc plate located inside the material stirring ring, and when the material laying arc plate is rotated and unfolded, the axes of the blowing holes point to the axis of the material stirring ring.
[0016] By adopting the above technical solution, when the paving arc plate rotates and expands, the blowing hole blows the material at the axis of the stirring ring, which is beneficial to reduce the blind area of paving the material in the stirring ring and further improves the paving effect of the material at the filling port of the ton bag.
[0017] Optionally, the paving assembly includes a vibration frame arranged on the frame, the vibration frame is provided with a vibration motor electrically connected to the control system, the vibration frame is provided with a vibration frame, and the vibration frame is used to abut against the support plate of the ton bag.
[0018] By adopting the above technical solution, when the material injection is completed, the worker starts the vibration motor through the control system. The vibration motor transmits the vibration to the support plate of the ton bag through the vibration frame and the vibration rack, causing the ton bag to vibrate, thereby flattening the material accumulated at the filling port of the ton bag, thereby reducing the impact of the material accumulated at the filling port of the ton bag on the bag sealing.

[0020] By adopting the above technical solution, when the material injection is completed, the worker starts the bag lifting cylinder through the control system, and rotates the hooks in turn through multiple bag lifting cylinders, so that the ears on the ton bag are shaken in turn, so that the materials accumulated at the filling port of the ton bag are shaken flat, thereby reducing the impact of the materials accumulated at the filling port of the ton bag on the bag sealing.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The worker first hangs the lifting lug of the ton bag on the hook, and then starts the electric slide rail through the control system. The moving end of the electric slide rail drives the hook to move backward, so that the lifting lug of the ton bag is unfolded. Then the worker starts the lifting cylinder through the control system. The lifting cylinder drives the bag lifting frame to rise by contracting its piston rod. The bag lifting frame lifts the lifting lug of the ton bag through the hook. Then the worker puts the filling port of the ton bag on the bag fixing pipe, and then fixes the filling port of the ton bag on the feeding pipe through the bag fixing component. The feeding pipe injects materials into the ton bag. After stopping injecting materials into the ton bag, the worker uses the paving component to flatten the materials accumulated at the filling port of the ton bag;
[0023] 2. After the middle tube is pressed against the feeding tube, the air pump pumps air into the cavity surrounded by the feeding tube, the inner tube and the middle tube through the electric three-way valve and the air blowing tube. The air flows into the cavity of the material laying arc plate through the air supply pipe and the rotating shaft tube, and is discharged from the exhaust hole on the material laying arc plate. The reaction force of the high-pressure air discharged from the exhaust hole blowing to the containing groove pushes the material laying arc plate to expand. The reset compression spring is squeezed and deformed by the material laying arc plate. The axis of the exhaust hole on the expanded material laying arc plate is inclined relative to the axis of the stirring ring, so that the stirring material rotates around the axis of the anti-slip ring. At the same time, the stirring ring drives the material laying arc plate to rotate, so as to flatten the piled materials.
[0024] 3. When the material injection is completed, the worker starts the bag lifting cylinder through the control system, and rotates the hooks in turn through multiple bag lifting cylinders, so that the ears on the ton bag are shaken in turn, so that the materials accumulated at the filling port of the ton bag are shaken flat, thereby reducing the impact of the materials accumulated at the filling port of the ton bag on the bag sealing.

[0042] Reference Figure 2 , Figure 3 and Figure 4 A clamp 94 is rotatably arranged on the bag lifting frame 4, and the clamp 94 is used to press the injection port of the ton bag 0 onto the annular airbag 91. A rotating cylinder 95 for driving the clamp 94 to rotate is arranged on the bag lifting frame 4, and the rotating cylinder 95 is electrically connected to the control system.
[0043] The worker first hangs the lifting lug of the ton bag 0 on the hook 6, and then starts the four electric slide rails 5 through the control system. The moving ends of the four electric slide rails 5 drive the hooks 6 thereon to move away from each other, so that the four lifting lugs on the ton bag 0 are unfolded. Then the worker puts the injection port of the ton bag 0 on the solid bag tube 8, and then the control system starts the rotating cylinder 95.
[0044] The output shaft of the rotating cylinder 95 drives the clamp 94 to rotate, and the clamp 94 rotates and buckles the injection port of the ton bag 0 on the annular air bag 91 on the solid bag tube 8. Then the worker starts the air pump 92 and the electric three-way valve 16 through the control system. The air pump 92 inflates the annular air bag 91 through the electric three-way valve 16 and the air pipe 93. The annular air bag 91 is inflated and expands to press the injection port of the ton bag 0 against the clamp 94.
[0045] Afterwards, the worker starts the lifting cylinder 7 through the control system. The lifting cylinder 7 drives the bag lifting rack 4 to rise by contracting its piston rod. The bag lifting rack 4 lifts the lifting lug of the ton bag 0 through the hook 6. At this time, the worker controls the electric three-way valve 16 through the control system, and the air pump 92 blows air into the feeding pipe 3 through the electric three-way valve 16 and the air pipe 15, thereby expanding the ton bag 0.
[0046] Then the feeding pipe 3 injects material into the ton bag 0, and at the same time the control system starts the exhaust fan 13, the exhaust fan 13 extracts the air in the ton bag 0 through the dust exhaust pipe 14, and the dust in the air is isolated in the ton bag 0 by the annular screen 12. When the injection of material into the ton bag 0 is stopped, the worker uses the paving component 10 to flatten the material accumulated at the injection port of the ton bag 0.
[0047] Reference Figure 3 , Figure 4 and Figure 5 The paving assembly 10 includes an inner tube 100 which is bolted to the frame 1 and is vertical. The top of the inner tube 100 and the top of the feeding tube 3 are blocked by the frame 1. The inner tube 100 extends to the top of the frame 1. The inner tube 100 is coaxially arranged inside the feeding tube 3. An intermediate tube 101 is coaxially slidably arranged between the inner tube 100 and the feeding tube 3.
[0048] Reference Figure 3 , Figure 4 and Figure 5 A vertical tube-pushing cylinder 102 electrically connected to the control system is bolted on the frame 1. The top of the intermediate tube 101 is bolted on the piston rod of the tube-pushing cylinder 102. The intermediate tube 101 is in close contact with the outer wall of the inner tube 100. The outer diameter of the intermediate tube 101 gradually decreases along the direction from the tube-pushing cylinder 102 to the intermediate tube 101. The inner hole diameter of the feeding tube 3 gradually decreases along the direction from the tube-pushing cylinder 102 to the intermediate tube 101.
[0049] Reference Figure 4 , Figure 5 and Figure 6 A stirring ring 103 is rotatably arranged at one end of the intermediate tube 101 facing away from the tube pushing cylinder 102, and a plurality of material spreading arc plates 104 are rotatably arranged on the stirring ring 103. The plurality of material spreading arc plates 104 are evenly arranged circumferentially along the axis of the stirring ring 103. A receiving groove 105 for accommodating the material spreading arc plates 104 is provided on the stirring ring 103, and a rotating part 106 for driving the material spreading arc plates 104 to rotate is arranged on the intermediate tube 101.
[0050] Reference Figure 4 , Figure 5 and Figure 6 The rotating member 106 includes an anti-slip ring 1061 coaxially arranged at the end of the intermediate tube 101, and the stirring ring 103 is rotatably arranged on the anti-slip ring 1061. The stirring ring 103 is coaxially provided with an annular air groove 1062 at one end facing the intermediate tube 101. An air supply pipe 1063 is arranged on the intermediate tube 101 along the direction from the intermediate tube 101 to the stirring ring 103. The air supply pipe 1063 passes through the anti-slip ring 1061 and communicates with the annular air groove 1062. The interior of the paving arc plate 104 is hollow.
[0051] Reference Figure 4 , Figure 5 and Figure 6 A vertical rotating shaft tube 1064 is coaxially arranged at the rotation center of the laying arc plate 104, one end of the top of the rotating shaft tube 1064 is connected to the annular air groove 1062, and the bottom end is connected to the interior of the laying arc plate 104, and an exhaust hole 1065 connected to the interior of the laying arc plate 104 is provided on the side of the laying arc plate 104 facing the side wall of the receiving groove 105, and a return compression spring 1066 is supported between the laying arc plate 104 and the receiving groove 105, and the return compression spring 1066 is used to press the laying arc plate 104 against the receiving groove 105.
[0052] Reference Figure 4 , Figure 5 and Figure 6 When the stirring ring 103 rotates, one end of the material spreading arc plate 104 is located inside the stirring ring 103, and the other end is located outside the stirring ring 103. The length of the material spreading arc plate 104 outside the stirring ring 103 is longer than the length of the material spreading arc plate 104 located inside the stirring ring 103. A plurality of blowing holes 17 are provided on the material spreading arc plate 104 located inside the stirring ring 103. When the material spreading arc plate 104 rotates and unfolds, the axis of the blowing hole 17 points to the axis of the stirring ring 103.
[0053] When the material in the ton bag 0 stops being injected, the worker starts the tube pushing cylinder 102 through the control system. The piston rod of the tube pushing cylinder 102 pushes the intermediate tube 101 down until the circumferential outer wall of the intermediate tube 101 is pressed against the circumferential inner wall of the feeding tube 3. At this time, the intermediate tube 101 drives the stirring ring 103 to be inserted into the piled material in the ton bag 0. Then the worker starts the electric three-way valve 16 and the air pump 92 through the control system.
[0054] The air pump 92 pumps air into the cavity surrounded by the feeding pipe 3, the inner pipe 100 and the intermediate pipe 101 through the electric three-way valve 16 and the air blowing pipe 15. The air pressure in the cavity surrounded by the feeding pipe 3, the inner pipe 100 and the intermediate pipe 101 increases, and the high-pressure air flows into the annular air groove 1062 through the air supply pipe 1063, and then flows into the cavity of the material laying arc plate 104 through the rotating shaft tube 1064, and is discharged from the exhaust hole 1065 on the material laying arc plate 104.
[0055] The reaction force of the high-pressure air discharged from the exhaust hole 1065 and blown to the receiving groove 105 pushes the material-laying arc plate 104 to expand, and the return compression spring 1066 is squeezed and deformed by the material-laying arc plate 104. Since the length of the material-laying arc plate 104 outside the stirring ring 103 is longer than the length of the material-laying arc plate 104 inside the stirring ring 103, more exhaust holes 1065 can be opened on the material-laying arc plate 104 outside the stirring ring 103.
[0056] When the stirring ring 103 rotates, the spreading arc plate 104 located outside the stirring ring 103 can provide greater centrifugal force. The axis of the exhaust hole 1065 on the unfolded spreading arc plate 104 is inclined relative to the axis of the stirring ring 103, so that the stirring ring 103 rotates around the axis of the anti-slip ring 1061, and the stirring ring 103 drives the spreading arc plate 104 to rotate synchronously, and the spreading arc plate 104 flattens the material accumulated at the injection port 0 of the ton bag.
[0057] The implementation principle of Example 1 is as follows: the worker first hangs the lifting lug of the ton bag 0 on the hook 6, and then starts the four electric slide rails 5 through the control system. The moving ends of the four electric slide rails 5 drive the hooks 6 thereon to move away from each other, so that the four lifting lugs on the ton bag 0 are unfolded, and then the worker puts the filling port of the ton bag 0 on the solid bag tube 8, and then the control system starts the rotating cylinder 95.
[0058] The output shaft of the rotating cylinder 95 drives the clamp 94 to rotate, and the clamp 94 rotates and buckles the injection port of the ton bag 0 on the annular air bag 91 on the solid bag tube 8. Then the worker starts the air pump 92 and the electric three-way valve 16 through the control system. The air pump 92 inflates the annular air bag 91 through the electric three-way valve 16 and the air pipe 93. The annular air bag 91 is inflated and expands to press the injection port of the ton bag 0 against the clamp 94.
[0059] Afterwards, the worker starts the lifting cylinder 7 through the control system. The lifting cylinder 7 drives the bag lifting rack 4 to rise by contracting its piston rod. The bag lifting rack 4 lifts the lifting lug of the ton bag 0 through the hook 6. At this time, the worker controls the electric three-way valve 16 through the control system, and the air pump 92 blows air into the feeding pipe 3 through the electric three-way valve 16 and the air pipe 15, thereby expanding the ton bag 0.
[0060] Then the feeding pipe 3 injects material into the ton bag 0, and at the same time the control system starts the exhaust fan 13, the exhaust fan 13 extracts the air in the ton bag 0 through the dust exhaust pipe 14, and the dust in the air is isolated in the ton bag 0 by the annular screen 12. When the injection of material into the ton bag 0 is stopped, the worker uses the paving component 10 to flatten the material accumulated at the injection port of the ton bag 0.
[0061] When the material in the ton bag 0 stops being injected, the worker starts the tube pushing cylinder 102 through the control system. The piston rod of the tube pushing cylinder 102 pushes the intermediate tube 101 down until the circumferential outer wall of the intermediate tube 101 is pressed against the circumferential inner wall of the feeding tube 3. At this time, the intermediate tube 101 drives the stirring ring 103 to be inserted into the piled material in the ton bag 0. Then the worker starts the electric three-way valve 16 and the air pump 92 through the control system.
[0062] The air pump 92 pumps air into the cavity surrounded by the feeding pipe 3, the inner pipe 100 and the intermediate pipe 101 through the electric three-way valve 16 and the air blowing pipe 15. The air pressure in the cavity surrounded by the feeding pipe 3, the inner pipe 100 and the intermediate pipe 101 increases, and the high-pressure air flows into the annular air groove 1062 through the air supply pipe 1063, and then flows into the cavity of the material laying arc plate 104 through the rotating shaft tube 1064, and is discharged from the exhaust hole 1065 on the material laying arc plate 104.
[0063] The reaction force of the high-pressure air discharged from the exhaust hole 1065 and blown to the receiving groove 105 pushes the material-laying arc plate 104 to expand, and the return compression spring 1066 is squeezed and deformed by the material-laying arc plate 104. Since the length of the material-laying arc plate 104 outside the stirring ring 103 is longer than the length of the material-laying arc plate 104 inside the stirring ring 103, more exhaust holes 1065 can be opened on the material-laying arc plate 104 outside the stirring ring 103.
[0064] When the stirring ring 103 rotates, the spreading arc plate 104 located outside the stirring ring 103 can provide greater centrifugal force. The axis of the exhaust hole 1065 on the unfolded spreading arc plate 104 is inclined relative to the axis of the stirring ring 103, so that the stirring ring 103 rotates around the axis of the anti-slip ring 1061, and the stirring ring 103 drives the spreading arc plate 104 to rotate synchronously, and the spreading arc plate 104 flattens the material accumulated at the injection port 0 of the ton bag.
[0065] Example 2
[0066] refer to Figure 7 The difference between this embodiment and embodiment 1 is that: the flattening component 10 includes a vibration frame 107 arranged at the bottom of the frame 1, an air spring (not shown in the figure) is arranged between the vibration frame 107 and the frame 1, the vibration frame 107 is located below the conveyor 2, and a vibration motor 108 electrically connected to the control system is bolted to the vibration frame 107, and a vibration frame 109 is welded to the vibration frame 107, and the vibration frame 109 is used to abut against the support plate of the ton bag 0.
[0067] The implementation principle of Example 2 is: when the material injection is completed, the worker starts the vibration motor 108 through the control system, and the vibration motor 108 causes the vibration frame 107 to vibrate and vibrate continuously. The vibrating vibration frame 107 drives the vibration frame 109 to continuously knock on the support plate at the bottom of the ton bag 0, and transmits the vibration to the material in the ton bag 0, so that the material accumulated at the injection port of the ton bag 0 in the ton bag 0 is flattened.
[0068] Example 3
[0069] refer to Figure 8The difference between this embodiment and embodiment 1 is that the paving assembly 10 includes a mounting plate 18 bolted to the moving end of the electric slide rail 5, a bag lifting cylinder 1010 is rotatably arranged on the mounting plate 18, the bag lifting cylinder 1010 is electrically connected to the control system, and a hook 6 is rotatably arranged on the mounting plate 18, and the hook 6 is rotatably connected to the piston rod of the bag lifting cylinder 1010.
[0070] The implementation principle of Example 3 is: when the material injection is completed, the worker starts the bag lifting cylinder 1010 through the control system, and rotates the hook 6 in turn through multiple bag lifting cylinders 1010, so that the lifting ears on the ton bag 0 are shaken irregularly in turn. Since the lifting ears are around the ton bag 0, the shaking of the lifting ears on the ton bag 0 causes the material accumulated at the injection port of the ton bag 0 to be shaken flat around.
[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
