DETAILED DESCRIPTION

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 7A high-performance woven bag that can prevent damage and edge bursting caused by bagging impact includes a woven bag body 1. The outer walls on both sides of the woven bag body 1 are connected to extension parts 14 through telescopic parts 5.

A connecting plate 8 is provided between the two adjacent fixing belts 9. The two connecting plates 8 are provided with an adjustment mechanism for adjusting the length of the multiple fixing belts 9.

[0030] As a technical optimization solution of the present invention, a first slider 11 is mounted on the outer wall of each of the two extensions 14 on the side away from each other, and a first chute adapted for the two first sliders 11 is formed on the outer wall of each of the plurality of movable plates 7 on the side close to the extensions 14. The plurality of movable plates 7 are respectively inserted and matched with the two first sliders 11, thereby reinforcing the two extensions 14 and improving their impact resistance.

[0031] As a technical optimization solution of the present invention, an opening portion 2 is installed at the top of the woven bag body 1. A second slider 3 is installed at the end of the opening portion 2 away from the woven bag body 1, which is compatible with the first slide groove of the multiple movable plates 7. The two opposite outer walls of the opening portion 2 are connected to handles 4 for facilitating the lifting of the woven bag body 1. The handles 4 provided on the outer walls of the opening portion 2 can facilitate the staff to carry the woven bag body 1 filled with materials, and can also facilitate the opening portion 2 to be opened during the bagging process of the woven bag body 1, so that the materials can enter the interior of the woven bag body 1. After two of the movable plates 7 are inserted and adapted to the second slider 3, the opening portion 2 can be sealed, thereby extending the shelf life of the materials inside the woven bag body 1.

[0032] As a technical optimization solution of the present invention, a second sliding groove 21 is provided on the outer wall of the side of multiple movable plates 7 away from the extension portion 14, a fourth slider 22 is installed in each of the second sliding grooves 21, and an installation groove 23 is provided on the outer wall of the side of multiple fourth sliders 22 away from the second sliding groove 21, and the ends of multiple fixing belts 9 close to the movable plate 7 are detachably connected to the installation groove 23 through the installation block 24.

[0033] As a technical optimization solution of the present invention, the adjustment mechanism includes multiple first winding rollers 25 rotatably installed inside the two connecting plates 8, and multiple fixed belts 9 extend from one end of the movable plate 7 to the inside of the connecting plate 8 close to it and are wrapped around the outer wall of the corresponding first winding roller 25. One end of the rotating shaft of the multiple first winding rollers 25 passes through the connecting plate 8 and is connected to a rotating part 26, and the outer wall of the multiple rotating parts 26 is provided with multiple limiting holes 27.

[0034] As a technical optimization solution of the present invention, two fixing plates 31 are installed on the outer walls of the two connecting plates 8 on the side closest to the multiple rotating parts 26. Two sliding plates 28 are slidably installed between the two fixing plates 31. A connecting spring 29 is installed between the two sliding plates 28. The outer walls of the two sliding plates 28 on the side away from each other are each installed with a limiting rod 30 that is compatible with the limiting holes 27 on the outer walls of the two rotating parts 26. The provided adjustment mechanism can adjust the length of the multiple fixing straps 9, facilitating the use of the fixing straps 9 for different functions.

[0035] As a technical optimization solution of the present invention, a second winding roller 17 is rotatably mounted on the outer wall of the same side of the two movable plates 7. The outer walls of the two second winding rollers 17 are wrapped with a protective film 18. A connecting strip 19 is installed on the end of each protective film 18 away from the second winding roller 17. The outer walls of the two movable plates 7 away from the second winding roller 17 are each provided with a connecting groove 20 adapted to the connecting strip 19. The protective film 18 can protect the woven bag body 1 and extend the service life of the woven bag body 1.

[0036] As a technical optimization solution of the present invention, a third slider 10 adapted to the first slide groove of the multiple movable plates 7 is installed at the bottom of the woven bag body 1, and grooves 16 are provided at both ends of the third slider 10. The outer walls of one side of the bottom end of the two extensions 14 close to the third slider 10 are both installed with connecting blocks 15, and the two connecting blocks 15 are respectively inserted and adapted to the two grooves 16.

[0037] As a technical optimization solution of the present invention, connecting ends 12 are installed on the other two opposite outer walls of the opening 2, and the top ends of the two extensions 14 are connected to the connecting ends 12 through connecting pieces 13.

[0038] As a technical optimization solution of the present invention, multiple anti-slip strips 6 are installed on two opposing outer walls of the woven bag body 1. The multiple anti-slip strips 6 on one outer wall of the woven bag body 1 are inserted and adapted to the gaps between the multiple anti-slip strips 6 on the other outer wall of the woven bag body 1. The provision of anti-slip strips 6 on the surface of the woven bag body 1 can prevent the woven bag bodies 1 on the upper side from sliding downward after the woven bag bodies 1 filled with materials are stacked, thereby improving the safety of the stacking.

[0039] In the present invention, before using the woven bag body 1 to collect materials, the staff can slide the two movable plates 7 near the bottom end of the woven bag body 1 downward to remove them, and respectively insert the two movable plates 7 at the two ends of the third slider 10, so that at this time multiple movable plates 7 are respectively located on both sides and the bottom of the woven bag body 1, providing auxiliary support and fixation for the two extension parts 14 and the bottom, avoiding accidents such as damage and edge bursting of the woven bag body 1, and indirectly improving the bagging efficiency of the materials.

[0040] After a portion of the material is collected inside the woven bag body 1, the two movable plates 7 at the bottom of the woven bag body 1 can be reset, and one of the fixing straps 9 near the top of the woven bag body 1 and the other fixing strap 9 near the bottom of the woven bag body 1 can be removed, and then the ends of the two fixing straps 9 that have been removed are connected to the mounting grooves 23 of the fourth slider 22 opposite to them, so that the multiple fixing straps 9 at this time can be matched with each other and respectively located on both sides of the woven bag body 1 to provide auxiliary support for the outer wall of the woven bag body 1, thereby further improving the impact resistance of both sides of the woven bag body 1.

[0041] When the woven bag body 1 needs to be used to collect more materials, the two extension parts 14 and the connecting piece 13 at the top of the opening part 2 can be removed, and then the two extension parts 14 can be pulled away from each other, driving the telescopic part 5 to be extended, so that the internal volume of the woven bag body 1 is increased at this time, and more materials can be collected.

[0042] After collecting a sufficient amount of material inside the woven bag body 1, a sealing machine is used to seal the opening 2, and then the multiple movable plates 7 on both sides of the woven bag body 1 are reset, and the multiple fixing belts 9 are reset at the same time. The staff can now manually hold the two connecting plates 8 to manually carry the woven bag body 1 filled with materials; when the staff carries the woven bag body 1 filled with materials to a designated location for stacking and storage, the multiple woven bag bodies 1 can be stacked according to the multiple anti-slip strips 6 set on the outer walls on both sides thereof, so that during the stacking and storage process of the multiple woven bag bodies 1 filled with materials, it is not easy for the upper woven bag body 1 to fall down.

[0043] If the woven bag bodies 1 filled with materials are to be stacked in an exposed transport compartment or in the external environment, in order to prevent the woven bag bodies 1 filled with materials stacked on top from aging or damage, the protective film 18 wrapped around the outer walls of the two second winding rollers 17 at the top can be pulled out and covered on the top of the stacked woven bag bodies 1 filled with materials. Since the protective film 18 is made of dark-colored UV-proof material, it can protect the woven bag bodies 1 stacked in the exposed compartment and the external environment, and reduce the aging of the woven bag bodies 1 on the top; and at this time, the fixing belt 9 on the same movable plate 7 as the second winding roller 17 can also be removed, and the top protective film 18 can be tied and fixed to prevent the protective film 18 from being blown away by the external wind and losing its protective effect.

[0044] At the same time, when the woven bag body 1 filled with materials needs to be hoisted upward to a high-rise location for storage, the two sliding plates 28 on the outer wall on the same side of the two connecting plates 8 can be moved in the direction of approaching each other, driving the connecting spring 29 to be compressed. When the two sliding plates 28 are moved in the direction of approaching each other, the limiting rods 30 on the side away from the two sliding plates 28 can be driven to move out from the limiting holes 27 corresponding to the outer wall of the rotating part 26. At this time, the rotating part 26 is not limited and fixed by the limiting rods 30, so that the first winding roller 25 inside the connecting plate 8 can rotate freely. The staff can pull the fixing belt 9 to extend to the specified length, and then release the limit of the two sliding plates 28, drive the connecting spring 29 to elastically reset, so that the two limiting rods 30 can be respectively inserted into the corresponding limit positions at this time. Inside the hole 27, the rotation of the rotating part 26 and the first winding roller 25 is continued to be limited and fixed. Finally, the staff can pull the two connecting plates 8 upward and fix them with the help of the lifting rope of the lifting equipment. Then, multiple woven bag bodies 1 filled with materials can be lifted upward in turn; and in order to improve the efficiency of lifting the woven bag bodies 1 filled with materials, the telescopic parts 5 on both sides of the woven bag bodies 1 without materials inside can be stretched to an expanded state, so that the area of the woven bag body 1 is expanded. The woven bag body 1 expanded at this time can be used as a lifting and placement platform, and other woven bag bodies 1 filled with materials can be placed on the woven bag body 1 in the expanded state, and lifted upward in a concentrated manner, thereby speeding up the lifting of the woven bag bodies 1 filled with materials and improving the lifting efficiency.

[0045] When people need to use the materials inside the woven bag body 1, they need to remove the sealing line of the opening 2. However, after the sealing line of the opening 2 is removed, the woven bag body 1 loses its sealing effect on the materials. At this time, two of the movable plates 7 close to the opening 2 can be slid upward and removed, and the two movable plates 7 are respectively inserted at the two ends of the second slider 3 at the top of the opening 2, so that the two movable plates 7 can assist in sealing the opening 2, thereby preventing the opening 2 from being open after the materials inside the woven bag body 1 are used. External debris can easily enter the interior of the woven bag body 1 through the open opening 2, causing contamination to the materials and affecting the shelf life of the materials.

[0046] When stacking and storing unused woven bag bodies 1, multiple woven bag bodies 1 can be stacked and then the stacked woven bag bodies 1 can be bundled and packed with the help of two fixing straps 9 or protective films 18 of the bottom woven bag body 1. There is no need to use other external ropes for bundling and packing, which further improves the packing efficiency of the unused woven bag bodies 1.

[0047] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the content of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
