[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-6 , in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0029] A woven bag grooving device for packaging includes a frame 1. An inner side of the frame 1 is provided with a mounting bracket 2. Above an inner side of the mounting bracket 2 is provided with a movable rod 3. Both ends of the movable rod 3 are fixedly installed with sliding blocks 6. A surface of the movable rod 3 is sleeved with a first mounting sleeve 4. Tops of both ends of an inner side of the mounting bracket 2 are fixedly installed with fixed cabinets 5. The sliding blocks 6 are slidably installed in the fixed cabinets 5. A bottom of an inner side of the fixed cabinet 5 is fixedly installed with a spring 7. One end of the spring 7 facing the sliding block 6 is fixedly connected to the sliding block 6. Tops of both sides of the mounting bracket 2 are fixedly installed with first stepping motors 8. An output shaft of the first stepping motor 8 penetrates to an inner side of the mounting bracket 2 and is fixedly installed with an eccentric wheel 9. One side of the eccentric wheel 9 extends into the fixed cabinet 5 and is adapted to the sliding block 6. Openings 10 adapted to the eccentric wheel 9 are formed on both sides inside the fixed cabinet 5.

[0030] The specific usage process is as follows: First, the woven bag enters from the conveying device 20, then passes through the inner side of the guiding roller 21, and then is cut by the cutting mechanism 22. Among them, the cutting mechanism 22 is used to cut the woven bag conveyed by the conveying device 20 for subsequent processing. When cutting, the stepping motor three 222 starts to push the movable block 223 downward, and the movable block 223 drives the cutting knife 224 to move downward to cut the woven bag, ensuring the normal and smooth progress of the woven bag processing work, providing convenience for the user's work, and cutting the woven bag into a size that meets the composite use standard. Then, it is sent into the frame 1 by the limiting roller one 17 and then continuously conveyed forward by the two conveying rollers 15. Specifically, when working, the conveying roller 15 drives the conveying wheel 16 to rotate, and all the conveying wheels 16 rotate in the same direction, thereby conveying the woven bag forward. During this period, the woven bag passes through the limiting roller one 17, and the limiting roller one 17 can also play a role in limiting and guiding the woven bag to ensure the normal conveyance of the woven bag and provide convenience for the user's work. In this process, under the action of the fixed roller 11 and the mouth-twisting roller 14, the mouth of the woven bag is twisted open. Specifically, when working, the stepping motor two 13 starts to drive the mouth-twisting roller 14 to rotate. The fixed roller 11 is located above the mouth-twisting roller 14. When twisting the mouth, the mouth-twisting roller 14 rotates along the surface of the woven bag, and the fixed roller 11 also adheres to the surface of the woven bag but does not rotate. In this way, one surface of the woven bag can be twisted open. It should be noted that according to the actual working conditions, the mounting sleeve two 12, the stepping motor two 13, and the mouth-twisting roller 14 can also be exchanged with the mounting sleeve one 4 and the fixed roller 11 for use, so as to provide convenience for the user's work. Finally, it is conveyed forward again. It should be noted that a slope can also be set between the cutting mechanism 22 and the limiting roller one 17 to facilitate the smooth forward conveyance of the woven bag and prevent the woven bag from being blocked in the machine. Among them, when the woven bag passes through the conveying roller 15 and the conveying wheel 16, the limiting roller two 18 can play a role in flattening the woven bag, ensuring the normal and smooth conveyance of the woven bag and the normal progress of the mouth-twisting work, and providing convenience for the user's work. When the woven bag is conveyed, it passes through the supporting plate 19. The supporting plate 19 can play a role in lifting the woven bag and also in guiding the woven bag, preventing the woven bag from being wound inside the machine by the conveying roller 15 and the conveying wheel 16, ensuring the normal operation of the machine equipment, and providing convenience for the user's work. Among them, the conveying device 20 is used to convey the woven bags that have been produced and connected together, and send the woven bags to the cutting mechanism 22 for cutting. During this period, the woven bag passes through the guiding roller 21, and the guiding roller 21 plays a role in limiting the woven bag, preventing the woven bag from warping or falling to the outside, and providing convenience for the user's work. In the mouth-twisting work, the stepping motors one 8 on both sides are started to work. The stepping motors one 8 drive the eccentric wheels 9 to rotate. The eccentric wheels 9 rotate in an eccentric trajectory. Therefore, when the eccentric wheels 9 rotate, they will press down the sliding blocks 6. The sliding blocks 6 will slide inside the fixed cabinet 5 and compress the springs 7 at the same time.Meanwhile, the two sliding blocks 6 will also drive the movable rod 3 to move downward. Furthermore, the first mounting sleeve 4 and the fixed roller 11 mounted on the movable rod 3 will also move downward and thus press on the surface of the woven bag. Finally, in cooperation with the mouth-twisting roller 14, the mouth-twisting of the woven bag is achieved.

[0031] Therefore, with an intermittent structural design, the mouth-twisting wheel can be lifted during the process from the mouth to the tail of the woven bag and then pressed down to perform the next mouth-twisting work after the mouth of the next packaging bag reaches the designated position. This can not only enable the smooth and unobstructed normal transportation of the woven bag but also ensure the accurate opening of the mouth of each woven bag, providing convenience for the user's work.

[0033] Specifically, with the settings of the fixed roller 11, the second mounting sleeve 12, the stepping motor two 13, and the mouth-twisting roller 14, when working, the stepping motor two 13 starts to drive the mouth-twisting roller 14 to rotate. The fixed roller 11 is located above the mouth-twisting roller 14. When twisting the mouth, the mouth-twisting roller 14 will rotate while sticking to the surface of the woven bag, and the fixed roller 11 also sticks to the surface of the woven bag but does not rotate. In this way, one surface of the woven bag can be opened. It should be noted that according to the actual working conditions, the second mounting sleeve 12, the stepping motor two 13, and the mouth-twisting roller 14 can also be swapped with the first mounting sleeve 4 and the fixed roller 11 for use, thus providing convenience for the user's work.

[0035] Specifically, with the settings of the conveying rollers 15, the conveying wheels 16, and the first limiting rollers 17, when working, the conveying rollers 15 drive the conveying wheels 16 to rotate. All the conveying wheels 16 rotate in the same direction, and then the woven bag is conveyed forward. During this period, the woven bag passes through the first limiting rollers 17, and the first limiting rollers 17 can also play a role in limiting and guiding the woven bag to ensure the normal transportation of the woven bag and provide convenience for the user's work.

[0036] A second limiting roller 18 is rotatably installed at the top inside the mounting frame 2, and the second limiting roller 18 is located directly above one of the conveying rollers 15.

[0037] Specifically, the setting of the second limiting roller 18 can flatten the woven bag when the woven bag passes through the conveying roller 15 and the conveying wheel 16, ensuring that the woven bag can be transported normally and smoothly, and also ensuring the normal progress of the bag-twisting work, providing convenience for the user's work.

[0038] A support plate 19 is fixedly installed inside the mounting frame 2, and the bag-twisting roller 14, the conveying roller 15, and the conveying wheel 16 are all located inside the support plate 19.

[0039] Specifically, the setting of the support plate 19 enables the woven bag to pass over the support plate 19 during transportation. The support plate 19 can support the woven bag and also guide the woven bag, preventing the woven bag from being wound inside the machine by the conveying roller 15 and the conveying wheel 16, ensuring the normal operation of the machine equipment, and providing convenience for the user's work.
