Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

Ton bags are also called container bags, space bags, mother-and-child bags, etc. They are composed of inner bags and outer bags. The inner bag is used to hold materials, and the outer bag is used to protect the inner bag to prevent the inner bag from being scratched. When packaging existing ton bags, the outer bag needs to be placed outside the inner bag first, and then the materials are poured into the inner bag and the inner bag is sealed. Then, the sealed inner bag is completely stuffed into the outer bag manually, and finally the bag mouth of the outer bag is tied to complete the packaging of the ton bag. However, the packaging process is cumbersome, which increases the packaging time of the ton bag and affects work efficiency. In addition, there is uncertainty in manual labor. When tying the outer bag, the tying strength cannot be guaranteed. The outer bag is very likely to loosen due to insufficient tying strength, which causes the inner bag to fall out of the outer bag.

The present invention provides a packaging device and a ton bag packaging method, aiming to solve the technical problems of low packaging efficiency and unguaranteed packaging quality due to manual packaging in the prior art.

Please refer to Figures 1 and 2. In one embodiment of the present invention, the packaging equipment includes a frame 100, a bag feeding device 200, a bag sorting device 300, a bag plugging device 400 and a strapping device 500. The frame 100 is formed with a accommodating space 110. The bag feeding device 200 is arranged on the frame 100 and can transport ton bags to the accommodating space 110. The bag sorting device 300 includes a plurality of clamping components 310 for clamping outer bags; each clamping component 310 can move in a direction away from the accommodating space 110 to unfold the bag opening of the outer bag; the bag plugging device 400 can be inserted into the accommodating space 110 to stuff the part of the inner bag extending out of the outer bag into the outer bag. The strapping device 500 is arranged on the frame 100 and is used to strap the ton bags.

The technical solution of the present invention can sequentially complete the conveying of ton bags, the unfolding of the bag opening of the outer bag, the inserting of the inner bag and the bundling of the outer bag by setting a bag delivery device 200, a bag sorting device 300, a bag plugging device 400 and a bundling device 500, so as to realize the packaging of ton bags. The packaging device is used to replace manual labor to complete the packaging of ton bags, which can improve work efficiency, and can also ensure the bundling strength when bundling the outer bag, thereby ensuring the packaging quality of the ton bags. In this embodiment, the bag delivery device 200 is used to transport the ton bag with the sealed inner bag (the outer bag has been sleeved outside the inner bag) from the outside of the rack 100 to the accommodating space 110 of the rack 100. The clamping assembly 310 can move in a direction away from the accommodating space 110 to unfold the bag opening of the outer shell, so as to facilitate the bag plugging device 400 to insert the part of the inner bag extending out of the outer bag into the outer bag. The bag plugging device 400 can be inserted into the accommodating space 110 to insert the part of the inner bag extending out of the outer bag into the outer bag. The strapping device 500 can strap the outer bag after the inner bag is completely inserted into the outer bag. During packaging, the bag feeding device 200 first delivers the sealed inner bag to the accommodating space 110, the clamping assembly 310 clamps the edge of the outer bag and moves away from the accommodating space 110 to open the bag opening of the outer bag, then the bag inserting device 400 is inserted into the accommodating space 110 to insert the part of the inner bag extending out of the outer bag into the outer bag, and finally the strapping device 500 straps the bag opening of the outer bag to complete the packaging of the ton bag. The packaging equipment can sequentially complete the packaging of ton bags, the opening of the outer bag, the insertion of the inner bag and the bundling of the outer bag through the bag feeding device 200, the bag sorting device 300, the bag plugging device 400 and the bundling device 500 to achieve the packaging of ton bags. It can replace manual work to complete the packaging work of ton bags and improve the packaging efficiency of ton bags. It also uses a machine to bundle the outer bag, which can ensure the bundling strength to prevent the outer bag from loosening due to insufficient bundling strength, thereby preventing the inner bag from falling out of the outer bag, thereby ensuring the packaging quality.

It should be noted that the sealed inner bag has a sheet structure at the sealing portion, and when the outer bag is packaged, only the sheet structure at the sealing portion of the inner bag extends out of the outer bag. When the inner bag is completely stuffed into the outer bag, it is only necessary to stuff the sheet structure at the sealing portion of the inner bag into the outer bag. In addition to being applied to the field of ton bag packaging technology, the packaging equipment can also be applied to the field of single-layer bag packaging technology; for example, when the material is contained in a single-layer bag, the bag feeding device 200 first conveys the single-layer bag containing the material to the accommodating space 110, and then the clamping assembly 310 clamps the bag opening of the single-layer bag and moves in a direction away from the accommodating space 110 to unfold the bag opening of the outer bag, and then the bag plugging device 400 is inserted into the accommodating space 110 to compress the material in the single-layer bag, and finally the strapping device 500 straps the bag opening of the single-layer bag to complete the packaging of the single-layer bag.

Please refer to Figures 3 to 5. In one embodiment of the present invention, the bag sorting device 300 also includes a plurality of driving mechanisms 320. The driving mechanism 320 includes a slide rail 321 disposed on the frame 100, a slider 322 slidably disposed on the slide rail 321, a first driving body 323 disposed on the slide rail 321 and connected to the slider 322, and a second driving body 324 disposed on the slider 322. The clamping assembly 310 is connected to the second driving body 324. The first driving body 323 can drive the slider 322 to slide in a direction close to or away from the accommodating space 110. The second driving body 324 can drive the clamping assembly 310 to move along a first direction of the frame 100 in a direction close to or away from the accommodating space 110, wherein the first direction is the direction indicated by Z in Figure 3. In a specific embodiment, the first direction is a vertical direction. After the bag delivery device 200 delivers the ton bag to the accommodating space 110, the first driving body 323 drives the slider 322 to slide in the direction close to the accommodating space 110, thereby driving the clamping assembly 310 to slide in the direction close to the accommodating space 110, and then the second driving body 324 drives the clamping assembly 310 to descend. After the clamping assembly 310 clamps the bag edge of the outer bag, the first driving body 323 drives the slider 322 to slide again, so that the slider 322 slides in the direction away from the accommodating space 110, driving the clamping assembly 310 to slide in the direction away from the accommodating space 110, and through the joint action of the clamping assemblies 310 of the multiple driving mechanisms 320, the bag opening of the outer bag can be opened. The bag sorting device 300 drives the clamping assembly 310 to move along two different directions of the frame 100 through the first driving body 323 and the second driving body 324 to open the bag opening of the outer bag. It has the advantage of simple structure, can simplify the structure of the packaging equipment, and reduce the difficulty of manufacturing. In a specific embodiment, the first driving body 323 and the second driving body 324 can be an electric cylinder, a gas cylinder, an oil cylinder, etc. In a more specific embodiment, the second driving body 324 is arranged on the slider 322 in a lifting manner, and the slider 322 is provided with an electric cylinder capable of driving the second driving body 324 to lift and lower, and the second driving body 324 is a gas cylinder, wherein the running speed of the electric cylinder is lower than the running speed of the gas cylinder, therefore, when driving the clamping assembly 310 to descend, the electric cylinder can first drive the second driving body 324 to descend, so that the clamping assembly 310 descends to a suitable position to ensure the accurate position of the clamping assembly 310, and then the second driving body 324 drives the clamping assembly 310 to descend, so that the clamping assembly 310 quickly descends to the clamping position, reducing the time for the clamping assembly 310 to move to the clamping position, thereby improving the packaging efficiency.

In one embodiment of the present invention, there are two driving mechanisms 320, and the sliders 322 of the two driving mechanisms 320 can slide in the direction of approaching or moving away from each other. There are two clamping assemblies 310, and the two clamping assemblies 310 are arranged in a one-to-one correspondence with the two driving mechanisms 320. The sliders 322 are driven by the first driving body 323 to slide in the direction of approaching or moving away from each other, thereby driving the clamping assemblies 310 to slide in the direction of approaching or moving away from each other. Through the joint action of the two driving mechanisms 320, the bag opening of the outer bag can be unfolded, so that the bag stuffing device 400 can stuff the part of the inner bag extending out of the outer bag into the outer bag. Further, the clamping assembly 310 includes a mounting frame 311, a first clamping member 312 and a second clamping member 313, and the first clamping member 312 and the second clamping member 313 are arranged at intervals on the mounting frame 311. The first clamping member 312 and the second clamping member 313 are both used to clamp the bag edge of the outer bag. The two driving mechanisms 320 are each provided with two clamping members. When the bag sorting device 300 unfolds the bag opening of the outer bag, the four clamping members can cooperate with each other to unfold the bag opening of the outer bag into a square shape, which can increase the size of the bag opening after the outer bag is unfolded, thereby facilitating the bag plugging assembly to insert the part of the inner bag extending out of the outer bag into the outer bag; when assembling the clamping assembly 310, the spacing between the two clamping members can be set to different sizes to meet actual use requirements. In addition, the number of driving mechanisms 320 can also be three, four, etc., and the number of clamping members of the clamping assembly 310 can be three, four, etc., and according to actual use requirements, multiple clamping members can be set to be distributed in an arc shape so that the bag opening of the outer bag after unfolding presents different shapes; and the number of driving mechanisms 320 can also be one, which only needs to set corresponding connecting rod structures and linkage structures between the driving mechanism 320 and each clamping assembly 310 so that each clamping assembly can move synchronously.

Please refer to FIG. 5 . In one embodiment of the present invention, the first clamping member 312 and the second clamping member 313 each include a driving cylinder 3121 and two clamping rods 3122 cross-arranged on the driving cylinder 3121. The driving cylinder 3121 can drive the two clamping rods 3122 to rotate so that the two clamping rods 3122 move toward or away from each other. Specifically, the driving cylinder 3121 can drive the two clamping rods 3122 to rotate so that the two clamping rods 3122 move toward the direction of approaching each other, that is, the angle between the two clamping rods 3122 becomes smaller, so that the two clamping rods 3122 clamp the bag edge of the outer bag; the driving cylinder 3121 can also drive the two clamping rods 3122 to rotate so that the two clamping rods 3122 move toward the direction of moving away from each other, that is, the angle between the two clamping rods 3122 becomes larger, so that the two clamping rods 3122 loosen the bag edge of the outer bag. By driving two clamping rods 3122 to rotate through a driving cylinder 3121, the bag edge of the outer bag can be clamped or released, which can simplify the structure, reduce the difficulty of making the packaging equipment, and can also reduce the number of driving structures used, thereby reducing production costs. In a specific embodiment, the driving cylinder 3121 can be a clamping claw cylinder or a finger cylinder. In addition, one of the clamping rods 3122 can be set to be fixedly installed, and the driving cylinder 3121 drives the other clamping rod 3122 to rotate, so that the two clamping rods 3122 move in the direction of approaching or moving away from each other. In addition, in addition to using two cross-arranged clamping rods 3122 to clamp the bag edge of the outer bag, two clamping blocks 3123 that can move in the direction of approaching or moving away from each other can also be used for clamping, and according to actual needs, both clamping blocks 3123 can be set to slide, or one of the clamping blocks 3123 can be set to slide, and the other clamping block 3123 can be set to be fixedly installed.

In one embodiment of the present invention, the two clamping rods 3122 are provided with clamping blocks 3123 on the sides facing each other at the ends away from the driving cylinder 3121, and the bag edge of the outer bag can be clamped between the two clamping blocks 3123. When the clamping assembly 310 clamps the bag edge of the outer bag, the two clamping rods 3122 moving in the direction of approaching each other clamp the bag edge of the outer bag through the clamping blocks 3123. At this time, the contact between the two clamping blocks 3123 and the outer bag is line contact, which can prevent the bag edge of the outer bag from being unclamped or loosened after being clamped by the clamping assembly 310, thereby ensuring that the bag mouth of the outer bag can be normally opened under the action of the bag sorting device 300. In a specific embodiment, the clamping block 3123 can be in the shape of a hook, and in order to prevent the edge of the outer bag from slipping from between the two clamping blocks 3123 after the clamping block 3123 clamps the edge of the outer bag, a corresponding wear-resistant layer for increasing the friction force can be provided on the clamping block 3123, such as: coating the clamping block with rubber material.

Please refer to Figures 6 and 7. In one embodiment of the present invention, the bag stuffing device 400 includes a first driving unit 410 slidably disposed on the frame 100 along a first direction of the frame 100, a mounting base 420 disposed on the first driving unit 410, a second driving unit 430 disposed on the mounting base 420, and two clamping units 440 cross-arranged on the second driving unit 430. The frame 100 is provided with a third driving unit 120, and the third driving unit 120 can drive the first driving unit 410 to slide along the first direction of the frame 100. The first driving unit 410 can drive the mounting base 420 to slide along the first direction of the frame 100; the second driving unit 430 can drive the two clamping units 440 to rotate so that the two clamping units 440 move in a direction close to or away from each other, wherein the first direction refers to the direction indicated by Z in Figure 6.

After the bag delivery device 200 delivers the ton bag to the accommodating space 110, the third drive unit 120 first drives the first drive unit 410 to descend, and then the second drive unit 430 drives the two clamping units 440 to rotate, so that the two clamping units 440 move in a direction close to each other, clamp the part of the inner bag extending out of the outer bag, and prevent the part of the inner bag extending out of the outer bag from being separated from the mounting seat 420 during the process of inserting the inner bag into the outer bag, and finally the bag opening of the outer bag is opened by the bag sorting device 300. After the bag sorting device 300 opens the bag opening of the outer bag, the first drive unit 410 drives the second drive unit 430 to descend, thereby driving the part of the inner bag extending out of the outer bag clamped by the two clamping units 440 to descend, and inserting the part of the inner bag extending out of the outer bag into the outer bag. By driving the two clamping units 440 to rotate by one second drive unit 430 to clamp or release the bag edge of the outer bag, the structure can be simplified to reduce the difficulty of manufacturing the packaging equipment, and the number of driving structures used can also be reduced to reduce the manufacturing cost. In a specific embodiment, the first drive unit 410 and the third drive unit 120 can be electric cylinders, air cylinders, oil cylinders, etc., and the second drive unit 430 can be a clamping claw cylinder, a finger cylinder, etc., and one of the clamping units 440 can also be set to be fixedly installed, and the second drive unit 430 drives the other clamping unit 440 to rotate, so that the two clamping units 440 move toward or away from each other. There are two second drive units 430, and the two second drive units 430 are arranged at intervals on the mounting seat 420, and each second drive unit 430 is correspondingly provided with two clamping units 440; that is, by driving the four clamping units 440 to rotate through the two drive units 430, two different positions of the part of the inner bag extending out of the outer bag can be clamped at the same time to prevent the inner bag from slipping off the mounting seat.

In addition to clamping to limit the position of the part of the inner bag extending out of the outer bag, the bag plugging device 400 can also be realized by providing a receiving groove on the mounting seat 420, and the above two methods can be used at the same time. Specifically, the mounting seat 420 is provided with a receiving groove, which is used to accommodate the part of the inner bag extending out of the outer bag; when the first driving unit 410 drives the mounting seat 420 to move along the first direction of the frame and the part of the inner bag extending out of the outer bag is inserted into the outer bag, the inner bag is placed in the receiving groove; by providing a receiving groove on the mounting seat 420, the position of the part of the inner bag extending out of the outer bag can be limited to prevent the inner bag from slipping off the mounting seat.

In a more specific embodiment, the first driving unit 410 is a pneumatic cylinder, and the third driving unit 120 is an electric cylinder, wherein the running speed of the electric cylinder is lower than the running speed of the pneumatic cylinder. Therefore, when the third driving unit 120 drives the first driving unit 410 to descend, the speed is slower, which can make the position of the mounting seat 420 more accurate when it stops, thereby ensuring that the second driving unit 430 on the mounting seat 420 can drive the two clamping units 440 to rotate, clamp the part of the inner bag extending out of the outer bag, and also prevent the mounting seat 420 from interfering with the bag feeding. The first driving unit 410 drives the mounting seat 420 to descend and ascend at a relatively fast speed, which can quickly stuff the inner bag into the outer bag and quickly withdraw the mounting seat 420 from the outer bag, so that the bundling device 500 can quickly bundle the outer bag. At the same time, it can also prevent the inner bag from popping out of the outer bag. In order to prevent the inner bag from popping out of the outer bag after being completely stuffed into the outer bag, the first driving unit 410 can be controlled to drive the mounting seat 420 to rise and fall repeatedly to compact the inner bag to ensure that the inner bag will not pop out of the outer bag. In addition, one of the first driving unit 410 and the third driving unit 120 can be removed, and only one driving unit can be used to drive the mounting seat 420 to rise and fall, which can simplify the structure of the bag plugging device 400, thereby simplifying the structure of the packaging equipment and reducing the difficulty of manufacturing.

In this embodiment, in addition to being clamped by two rotating clamping units 440, the portion of the inner bag extending out of the outer bag can also be clamped by two clamping units 440 that can move toward or away from each other, and according to actual needs, both clamping units 440 can be set to slide, or one of the clamping units 440 can be set to slide and the other clamping unit 440 can be set to be fixed.

Please refer to FIGS. 8 to 10 . In one embodiment of the present invention, the bag feeding device 200 includes a base 210 slidably disposed on the frame 100, two mounting rods 220, two clamping rods 230, a first driving module 240, a second driving module 250 and a conveyor belt 260. The base 210 can slide along a first direction of the frame 100, the two mounting rods 220 are slidably disposed on the base 210 along a second direction of the frame 100, and each clamping rod 230 is slidably disposed on the mounting rod 220 along a third direction of the frame 100. The first driving module 240 is disposed on the base 210, and can drive the two mounting rods 220 to slide in the direction of approaching or moving away from each other; the second driving module 250 is arranged on the mounting rod 220, and can drive the two clamping rods 230 to extend out of the rack 100 or retract into the rack 100 along the third direction of the rack 100, the conveyor belt 260 is arranged at the bottom of the rack 100, and the conveyor belt 260 has a bearing surface for carrying ton bags, and the rack 100 is provided with a third driving module 130; the third driving module 130 is connected to the base 210, and can drive the base 210 to slide along the first direction of the rack 100. Among them, the first direction refers to the direction indicated by Z in Figure 8, the second direction refers to the direction indicated by X in Figure 8, and the third direction refers to the direction indicated by Y in Figure 8. The first driving module 240 can drive the two mounting rods 220 to slide in a direction of approaching or moving away from each other, thereby driving the two clamping rods 230 to slide in a direction of approaching or moving away from each other, so as to clamp or release the part of the inner bag extending out of the outer bag; the second driving module 250 can drive the clamping rod 230 to slide along the third direction of the frame 100, so as to drive the ton bag to move to the accommodating space 110 along the conveyor belt 260. The third driving module 130 can drive the base 210 to rise and fall. After the second driving module 250 moves the ton bag to the accommodating space 110 through the clamping rod 230, the bag plugging device 400 first clamps the part of the inner bag extending out of the outer bag, and then the first driving module 240 drives the two clamping rods 230 to separate through the mounting rod 220, and finally the third driving module 130 drives the base 210 to rise, which can prevent the bag plugging device 400 from colliding with the bag conveying device 200 when plugging the part of the inner bag extending out of the outer bag into the outer bag, thereby avoiding damage. In a specific embodiment, the conveyor belt 260 may be a roller conveyor belt 260 .

Please refer to FIG. 9 and FIG. 10. In a specific embodiment, the bag delivery device 200 further includes a synchronization rod 270, which is sequentially inserted into the two clamping rods 230, and both ends of the synchronization rod 270 are provided with limit blocks; by providing the synchronization rod 270, the synchronization of the two clamping rods 230 when sliding can be ensured, and the second driving module 250 only needs to drive one of the clamping rods 230 to slide, and the other clamping rod 230 can be driven to slide, which can simplify the structure and reduce the difficulty of manufacturing the packaging device. The bag delivery device 200 further includes a connecting rod assembly 280, which includes a first connecting rod 281, a second connecting rod 282 and a third connecting rod 283 which are hinged in sequence, and the end of the first connecting rod 281 away from the second connecting rod 282 is hinged to one of the mounting rods 220, the second connecting rod 282 is hinged to the base 210, and the end of the third connecting rod 283 away from the second connecting rod 282 is hinged to the other mounting rod 220. When the first driving module 240 drives one of the mounting rods 220 to slide, the connecting rod assembly 280 can drive the other mounting rod 220 to slide in the opposite direction, thereby causing the two mounting rods 220 to slide toward or away from each other. By providing the connecting rod assembly 280, one mounting rod 220 drives another mounting rod 220 to slide, which can reduce the number of driving structures and thus reduce the manufacturing cost of the packaging device.

Please refer to Figures 11 to 15. In one embodiment of the present invention, the strapping device 500 includes two tightening mechanisms 510. Each tightening mechanism 510 includes a base 511 disposed on the frame 100, a mounting plate 512 slidably disposed on the base 511 along the second direction of the frame 100, and a first driving member 513 disposed on the base 511 and connected to the mounting plate 512; each first driving member 513 can drive the corresponding mounting plate 512 to slide along the second direction of the frame 100, so that the mounting plates 512 of the two tightening mechanisms 510 are connected. The plates 512 slide along the second direction of the frame 100 toward each other; a tightening unit 514 is provided on one of the mounting plates 512, and the tightening unit 514 can slide along the third direction of the frame 100 to tighten the bag opening of the outer bag; a bundling unit 515 is provided on the other mounting plate 512, and the bundling unit 515 can bundle the bag opening of the outer bag tightened by the tightening unit 514, wherein the second direction refers to the direction indicated by X in Figures 11 and 15, and the third direction refers to the direction indicated by Y in Figure 15. The first driving member 513 drives the corresponding mounting plate 512 to slide along the second direction of the frame 100, so that the mounting plates 512 of the two tightening mechanisms 510 slide toward each other along the second direction of the frame 100, and the bag opening of the outer bag can be tightened in the second direction; the tightening unit 514 slides along the third direction of the frame 100, so that the bag opening of the outer bag can be tightened in the third direction, thereby realizing the tightening of the bag opening of the outer bag in the second direction and the third direction; the bundling unit 515 can bundle the bag opening of the outer bag that has been tightened in the second direction and the third direction. In a specific embodiment, the first driving member 513 may be an oil cylinder, a gas cylinder, etc. The base 511 includes a first seat body 5111 and a second seat body 5112. The first seat body 5111 is disposed on the frame 100, the second seat body 5112 is slidably disposed on the first seat body 5111 along the second direction of the frame 100, and the mounting plate 512 is slidably disposed on the second seat body 5112 along the second direction of the frame 100. Accordingly, there are two first driving members 513, and the two first driving members 513 are respectively used to drive the second seat body 5112 and the mounting plate 512 to slide. The first driving member 513 may be an electric cylinder, a gas cylinder, an oil cylinder, etc. By slidably mounting the mounting plate 512 on the second seat body 5112 and slidably mounting the second seat body 5112 on the first seat body 5111, the mounting plate 512 slides along the second direction of the frame 100, which can reduce the volume of the tightening mechanism 510, thereby reducing the volume of the packaging device. Specifically, when the mounting plate 512 slides the same distance, using multiple seats to realize the sliding of the mounting plate 512 is compared with using a single seat to realize the sliding of the mounting plate 512. In the sliding of the mounting plate 512 realized by multiple seats, a part of the sliding of the mounting plate 512 is driven by the second seat 5112, that is, the mounting plate 512 starts to slide from a position closer to the accommodating space 110, and the second seat 5112 and the first seat 5111 are stacked. Therefore, using multiple seats to realize the sliding of the mounting plate 512 can effectively reduce the volume of the tightening mechanism 510, thereby reducing the volume of the packaging device, and making the structure of the packaging device more compact.

Please refer to FIG. 14 and FIG. 15 . In one embodiment of the present invention, the tightening unit 514 includes two tightening blocks 5141 and two second driving members 5142.

The strapping unit 515 includes a strapping machine 5151 slidably arranged on the mounting plate 512 and a third driving member connected to the strapping machine 5151, and the third driving member can drive the strapping machine 5151 to slide along the second direction of the frame 100. After the two first driving members 513 drive the corresponding mounting plate 512 to slide along the second direction of the frame 100 to tighten the bag opening of the outer bag in the second direction, the two second driving members 5142 respectively drive the two tightening blocks 5141 to move in a direction of approaching each other to tighten the bag opening of the outer bag in the third direction. After the opening of the outer bag is tightened, the third driving member drives the strapping machine 5151 to slide along the second direction of the frame 100 to the tightened opening of the bag, and straps the opening of the outer bag. The strapping machine 5151 is used to strap the tightened outer bag, and the specific structure can refer to the existing handheld strapping machine. In a specific embodiment, the second driving member 5142 can be a cylinder, an oil cylinder, an electric cylinder, etc. Furthermore, in order to ensure the tightening effect when the tightening unit 514 tightens the bag opening of the outer bag, one side of the two tightening blocks 5141 can be extended out of the mounting plate 512 along the second direction of the frame 100. That is to say, when the two mounting plates 512 clamp the outer bag, the two tightening blocks 5141 are at the abutment of the two mounting plates 512, which can ensure that the tightening blocks 5141 tighten the bag opening of the outer bag after being tightened by the mounting plates 512; at the same time, a limiting groove can be provided on the side of the two tightening blocks 5141 facing each other, and when the bag opening of the outer bag is tightened, the outer bag is accommodated in the limiting groove; the limiting groove can limit the position of the outer bag to ensure the tightening effect when the outer bag is tightened. In a more specific embodiment, the limiting groove of each tightening block 5141 is gradually reduced from a side close to another tightening block 5141 to a side away from another tightening block 5141. Specifically, the cross section of the limiting groove is fan-shaped, which enables the outer bag to slide into the bottom of the limiting groove of the tightening block 5141 when the two tightening blocks 5141 tighten the outer bag, so as to ensure the tightening effect. Further, the cross section of the tightening block 5141 is U-shaped, and the two tightening blocks 5141 can be plugged into each other, which enables one of the tightening blocks 5141 to push the outer bag to the bottom of the limiting groove when the two tightening blocks 5141 tighten the bag opening of the outer bag in the third direction of the frame 100, thereby ensuring the tightening effect when the outer bag is tightened.

In order to ensure the stability when the second driving body is lifted and lowered on the slider, the first driving unit slides in the first direction, the base slides in the first direction, the mounting rod slides in the second direction, the clamping rod slides in the third direction, the tightening block slides in the second direction, the second base slides in the second direction, and the tightening block slides in the third direction, guide structures such as guide rails and guide rods can be set between the connection mechanisms. In this embodiment, the sliding of the base in the first direction is guided by the guide rod, and the sliding of other structures are guided by the guide rails.
