[0028] Exemplarily, the first driving member 124 may be a cylinder or a hydraulic cylinder etc.

[0029] In this embodiment, the bag feeding device 11 transfers an empty bag to the bag opening platform 121. At the same time, when the second suction cups 125 adsorb the bag mouth, the bag feeding device 11 remains stationary. The first driving member 124 pushes the flipping plate 123 to rotate downward around the fixing plate 122, and opens the bag mouth to a preset angle.

[0030] Reference Figures 1 to 2 As shown, in some embodiments, the bag feeding device 11 includes a first moving mechanism 111 and a grasping member 112, and the grasping member 112 is connected to the output end of the first moving mechanism 111.

[0031] Exemplarily, the first moving mechanism 111 can be a manipulator or a multi-axis truss platform, etc.

[0032] In this embodiment, the first moving mechanism 111 drives the grasping member 112 to move along a preset path, grasp an empty bag and transfer it to the bag opening platform 121, so as to realize the conveyance of the empty bag to the bag opening platform 121.

[0033] Reference Figure 2 As shown, in some embodiments, the grasping member 112 includes a mounting portion 1121 and a plurality of first suction cups 1122.

[0034] Exemplarily, the mounting portion 1121 can be a plate-like structure, etc.

[0035] In this embodiment, the plurality of first suction cups 1122 adsorb the empty bags in the bag bin 13 through negative pressure, which can disperse the adsorption force, thereby preventing the bags from slipping or deforming.

[0036] Reference Figure 1 As shown, in some embodiments, the bag feeding device 11 includes a bag bin 13, and the bag bin 13 is disposed opposite to the bag opening platform 121.

[0037] In this embodiment, the bag bin 13 stores the empty bags centrally, and the grasping member 112 takes the bags as needed.

[0038] Reference Figures 4 to 5 As shown, in some embodiments, the bagging assembly 20 includes a bag sleeving device 21 and a feeding device 22. The bag sleeving device 21 is disposed opposite to the bag opening device 12, the feeding device 22 is disposed opposite to the bag sleeving device 21, the feeding device 22 includes a feeding hopper 221 and a pair of bag mouth clamping mechanisms 222, the pair of bag mouth clamping mechanisms 222 are axisymmetric about a first defined axis L1, and the bag mouth clamping mechanism 222 includes a first clamp 2223.

[0039] In this embodiment, the bag sleeving device 21 receives the opened empty bag, and at the same time transfers the empty bag to the discharge port of the feeding hopper 221 and aligns the center of the bag mouth of the empty bag with the discharge port of the feeding hopper 221. Subsequently, a pair of first clamps 2223 clamp both sides of the bag mouth of the empty bag, and the feeding hopper 221 can fill the bag with materials.

[0040] Reference Figures 5 to 6As shown, in some embodiments, the loading device 22 includes a connecting frame 2221 and a second driving member 2222. The first fixture 2223 is installed on the connecting frame 2221. A connecting rod 222131 is provided on the connecting frame 2221. The non-driving end of the second driving member 2222 is rotatably connected to the loading hopper 221, and the driving end of the second driving member 2222 is rotatably connected to the connecting rod 222131.

[0041] Exemplarily, the second driving member 2222 can be a cylinder, a hydraulic cylinder, or the like.

[0042] In this embodiment, after the first fixture 2223 releases the bag opening, the second driving member 2222 applies a thrust to the connecting rod 222131, causing the connecting frame 2221 to drive the first fixture 2223 away from the loading hopper 221, thereby reserving a moving space for the bag filled with materials.

[0043] Refer to Figure 6 As shown, in some embodiments, the connecting frame 2221 includes a first connecting plate 22211, a bearing plate 22212, and a connecting member 22213. The first connecting plate 22211 is fixed to the loading hopper 221. The bearing plate 22212 is disposed opposite to the first connecting plate 22211. The first connecting plate 22211 and the bearing plate 22212 are connected by at least two pairs of connecting members 22213. The first fixture 2223 is installed on the bearing plate 22212. The connecting rod 222131 is connected to a pair of connecting members 22213 facing away from the loading hopper 221.

[0044] In this embodiment, when the second driving member 2222 applies a thrust to the connecting rod 222131, a pair of connecting members 22213 facing away from the loading hopper 221 rotate around the first connecting plate 22211, and a pair of connecting rods 222131 close to the loading hopper 221 follow and rotate around the first connecting plate 22211, causing the bearing plate 22212 to move away from the loading hopper 221, so as to keep a certain distance between the first fixture 2223 and the loading hopper 221.

[0045] Refer to Figure 5 and Figure 7 As shown, in some embodiments, the loading hopper 221 includes a loading portion and a pair of duckbill portions. The pair of duckbill portions are axisymmetric about the second defined axis L2. The loading device 22 includes a pair of duckbill opening and closing mechanisms 223. The duckbill opening and closing mechanisms 223 correspond to the duckbill portions one by one. The duckbill opening and closing mechanism 223 includes a connecting seat 2231 and a third driving member 2232. The connecting seat 2231 is disposed on the duckbill portion. The third driving member 2232 is connected to the loading portion through two connecting ears 22321. The driving end of the third driving member 2232 is rotatably connected to one end of the connecting seat 2231.

[0046] Exemplarily, the third driving member 2232 can be a cylinder, a hydraulic cylinder, or the like. One end of each of the two connecting lugs 22321 away from the main body portion is rotatably connected to the third driving member 2232.

[0047] In this embodiment, the third driving member 2232 drives the connecting seat 2231 to drive the duckbill portion to open or close, so as to guide the material to flow into the empty bag. In this way, not only can the duckbill portion open the bag mouth to form a funnel-shaped channel to reduce material splashing, but also the opening and closing angles of the pair of duckbill portions can be adjusted to adapt to different bag mouth sizes.

[0048] Refer to Figure 7 As shown, in some embodiments, the loading device 22 includes a pair of bag pressing mechanisms 224. The bag pressing mechanisms 224 correspond to the duckbill opening and closing mechanism 223 one by one. The bag pressing mechanism 224 includes a bag pressing arm 2241, a fourth driving member 2242, and a pressing plate 2243. One end of the bag pressing arm 2241 is rotatably connected to the other end of the connecting seat 2231. The non-driving end of the fourth driving member 2242 is rotatably connected to the connecting seat 2231, and the driving end of the fourth driving member 2242 is rotatably connected to the bag pressing arm 2241. The pressing plate 2243 is provided at the other end of the bag pressing arm 2241.

[0049] Exemplarily, the fourth driving member 2242 can be a cylinder, a hydraulic cylinder, or the like.

[0050] In this embodiment, when a pair of duckbill portions are inserted into the empty bag, the fourth driving member 2242 provides a thrust to the bag pressing arm 2241, so that the pressing plate 2243 is in close contact with the duckbill portion. In this way, the bag mouth can be clamped by the combination of the pressing plate 2243 and the duckbill portion, which can further prevent the bag from falling off.

[0051] Refer to Figure 7 As shown, in some embodiments, a first buffer pad 22431 is provided on one side of the pressing plate 2243 relative to the duckbill portion.

[0052] Exemplarily, the first buffer pad 22431 can be made of rubber material, such as silica gel.

[0053] In this embodiment, when the pressing plate 2243 contacts the bag mouth, the first buffer pad 22431 absorbs the impact force through elastic deformation, avoiding scratching or breaking the bag by the rigid pressing plate 2243. Moreover, the first buffer pad 22431 disperses the local pressure of the pressing plate 2243 to ensure that the bag mouth fits completely.

[0054] Refer to Figure 1 and Figure 8As shown, in some embodiments, the bagging assembly 20 includes a bag clamping and moving device 23. The bag clamping and moving device 23 is disposed opposite to the loading device 22. The bag clamping and moving device 23 includes a second moving mechanism 231, a second connecting plate 232, and at least a pair of second clamps 233. The second connecting plate 232 is disposed at the output end of the second moving mechanism 231. At least a pair of second clamps 233 are disposed on the side of the second connecting plate 232 facing away from the second moving mechanism 231. Each pair of second clamps 233 is axisymmetric about the third defined axis L3.

[0055] Exemplarily, the second moving mechanism 231 can be a manipulator or a multi-axis truss platform, etc.

[0056] In this embodiment, when the bag is filled with materials, the second clamp 233 clamps the bag mouth and is transferred in cooperation with the second moving mechanism 231 together with the bag filled with materials, thereby preventing the materials from spilling due to tilting.

[0057] Refer to Figures 8 to 9 As shown, in some embodiments, the second clamp 233 includes a mounting plate 2331, a first clamping plate 2332, a second clamping plate 2333, and a fifth driving member 2334. The mounting plate 2331 and the fifth driving member 2334 are both disposed on the second connecting plate 232. The first clamping plate 2332 is disposed on the mounting plate 2331. The second clamping plate 2333 is disposed opposite to the first clamping plate 2332. The output end of the fifth driving member 2334 is connected to the second clamping plate 2333.

[0058] Exemplarily, the fifth driving member 2334 can be a rotary cylinder or a motor, etc.

[0059] In this embodiment, before clamping the bag mouth filled with materials, the fifth driving member 2334 drives the second clamping plate 2333 to rotate, so that the second clamping plate 2333 moves away from the first clamping plate 2332. When one side of the bag mouth abuts against the first clamping plate 2332, the fifth driving member 2334 drives the second clamping plate 2333 to rotate again, so that the second clamping plate 2333 and the first clamping plate 2332 cooperate to clamp the bag mouth.

[0060] Refer to Figures 8 to 9 As shown, in some embodiments, the second clamp 233 includes a second buffer pad 2335. The clamping surface of the first clamping plate 2332 and / or the clamping surface of the second clamping plate 2333 is provided with the second buffer pad 2335.

[0061] Exemplarily, the second buffer pad 2335 can be made of rubber material, such as silica gel, etc.

[0062] In this embodiment, the second buffer pad 2335 can cover the clamping surfaces of the first clamping plate 2332 and / or the second clamping plate 2333, and adapt to the shape of the bag body through elastic deformation during clamping. In this way, the first buffer pad 22431 increases the frictional force and protects the surface of the bag body, avoiding clamping slippage or indentation marks.

[0063] Referring to Figures 8 to 9 As shown, in some embodiments, the bag clamping and moving device 23 includes a sixth driving member 234. The number of the sixth driving members 234 is associated with the number of the second clamps 233. The sixth driving members 234 correspond to the second clamps 233 one by one. The sixth driving members 234 are arranged on the side of the second connecting plate 232 away from the second moving mechanism 231, and the driving ends of the sixth driving members 234 are connected to the mounting plate 2331.

[0064] Exemplarily, the sixth driving member 234 can include a motor, a lead screw, a nut seat, etc. Alternatively, the sixth driving member 234 can be a lead screw mechanism or a slide table cylinder, etc.

[0065] In this embodiment, by adjusting the position of the mounting plate 2331 through the sixth driving member 234, the distance between a pair of second clamps 233 can be changed. In this way, bags of different widths can be compatible without replacing components.

[0066] Referring to Figure 1 As shown, in some embodiments, the packaging system includes a conveying unit 30. The conveying unit 30 is disposed opposite to the discharge port of the loading hopper 221. The conveying unit 30 includes a first conveying member 31.

[0067] Exemplarily, the first conveying member 31 can be a conveyor, etc.

[0068] In this embodiment, the first conveying member 31 receives the bags transferred by the bag sleeving and moving device, and provides a supporting function for the bags when loading materials. After the bags are filled with materials, the first conveying member 31 can convey the bags to the next process to achieve seamless connection.

[0069] Referring to Figure 1 As shown, in some embodiments, the conveying unit 30 includes a supporting assembly 32. The supporting assembly 32 is disposed opposite to the discharge port of the loading hopper 221. The supporting assembly 32 includes a lift 321 and a second conveying member 322. The second conveying member 322 is disposed on the lift 321, and the starting end of the conveying of the first conveying member 31 corresponds to the ending end of the conveying of the second conveying member 322.

[0070] Exemplarily, the second conveying member 322 can be a conveyor, etc.

[0071] In this embodiment, before bagging, the elevator 321 descends to reserve a bag feeding space for the bagging device 21 to prevent the bag from rubbing against the elevator 321. During bagging, the elevator 321 adjusts the position of the second conveyor 322 according to the height of the bag so that the second conveyor 322 supports the bag. After the bag is filled with materials, with the assistance of the bag clamping and moving device 23, the second conveyor 322 transports the bag onto the first conveyor 31.

[0072] Referring to Figure 1 As shown, in some embodiments, the packaging system includes a sewing machine 40. The sewing machine 40 is connected to the loading device 22 and is located above the first conveyor 31.

[0073] In this embodiment, the sewing machine 40 automatically sews the bag opening when the bag passes by, thus eliminating the need for manual intervention.

[0074] Referring to Figure 1 As shown, in some embodiments, the packaging system includes a shaping device 50. The shaping device 50 is arranged between the loading device 22 and the sewing machine 40.

[0075] In this embodiment, the shaping device 50 arranges the shape of the bag opening through a synchronous belt mechanism to make the bag opening flat and fitting. This ensures that there are no wrinkles at the bag opening, improves the sewing quality, and reduces the rework rate.

[0076] The specific implementation steps of the present invention are as follows: First step: The first moving mechanism 111 drives a plurality of first suction cups 1122 to move along a preset path, adsorb and transfer the empty bag to the bag opening platform 121. At the same time, when the second suction cup 125 adsorbs the bag opening, the bag feeding device 11 remains stationary, and the first driving member 124 pushes the turning plate 123 to rotate downward around the fixed plate 122, pulling the bag opening to a preset angle.

[0077] Second step: The second driving member 2222 applies a thrust to the connecting rod 222131, causing the connecting frame 2221 to drive the first clamp 2223 away from the loading hopper 221. The bagging device 21 receives the opened empty bag, and at the same time transfers the empty bag to the discharge port of the loading hopper 221 and inserts the duckbill part into the empty bag. Immediately afterwards, a pair of first clamps 2223 clamp both sides of the bag opening of the empty bag; the third driving member 2232 drives the connecting seat 2231 to drive the duckbill part to expand; the fourth driving member 2242 provides a thrust to the bag pressing arm 2241, making the pressing plate 2243 in close contact with the duckbill part.

[0078] Third step: When the loading hopper 221 fills the bag with materials, the elevator 321 rises to support the bag; after the bag is filled with materials, the duckbill opening and closing mechanism 223 drives the duckbill part to close, and both the bag opening clamping mechanism 222 and the bag pressing mechanism 224 release the bag opening. At the same time, the elevator 321 drives the bag to descend to a preset height.

[0079] Step 4: Before clamping the mouth of the bag filled with materials, the fifth driving member 2334 drives the second clamping plate 2333 to rotate, so that the second clamping plate 2333 moves away from the first clamping plate 2332. When one side of the bag mouth fits against the first clamping plate 2332, the fifth driving member 2334 drives the second clamping plate 2333 to rotate again, so that the second clamping plate 2333 and the first clamping plate 2332 cooperate to clamp the bag mouth.

[0080] Step 5: The second conveying member 322 conveys the bag filled with materials to the first conveying member 31, and shapes the bag mouth through the shaping device 50. At the same time, the second moving mechanism 231 cooperates with the second conveying member 322 to move.
