[0002] Woven bags are widely used across various industries. The folding process significantly impacts subsequent use and production efficiency. Traditional manual folding methods are inefficient and cannot meet the needs of large-scale production. This leads to longer production cycles and increased costs. Furthermore, manual operation results in poor precision and consistency, leading to inconsistent fold quality and affecting product image. Workers are prone to fatigue from repetitive labor, increasing the risk of workplace injuries. While mechanized folding equipment exists, problems arise when handling woven bags of varying lengths. Different customers have different requirements for bag length specifications, and many existing folding devices are not flexible enough. Different sizes of devices are needed to fold bags of varying lengths, posing numerous challenges for businesses. Companies need to maintain a variety of equipment sizes, significantly increasing procurement costs. Frequent equipment changes not only require considerable time and manpower for installation, debugging, and switching but also halt production lines, affecting continuity and efficiency. The maintenance methods for different equipment models vary greatly, increasing complexity and cost. Therefore, we propose a woven bag folding device. Utility Model Content

[0020] Compared with the prior art, the present invention provides a folding device for woven bags, which has the following advantages:
[0021] Improved production efficiency: Traditional manual folding is inefficient and cannot meet the needs of large-scale production, resulting in long production cycles. This device, however, adopts mechanized operation. A drive motor rotates a synchronous roller, which in turn drives the folding rod to move the folding plate to complete the folding action of the woven bag. The entire process is fast and continuous, greatly shortening the folding time and significantly improving production efficiency. It can easily handle large-scale production tasks and effectively reduce the production costs of enterprises.
[0022] Adaptable to woven bags of different lengths: By using the adjustable rod, the component plate moves the fixed shaft upwards by pulling the adjusting rod upwards. Then, according to the length of the woven bag, the folding plate is pushed to align with one end of the bag. After releasing the adjusting rod, the restoring force of the return spring pushes the component plate downwards, causing the fixed shaft to insert into the fixed circular groove where the folding plate stops, thus fixing the position of the folding plate. This allows the device to flexibly adapt to the folding requirements of woven bags of different lengths without the need to replace equipment, reducing the company's equipment procurement and maintenance costs and ensuring the continuity and stability of production.

[0029] Please see Figure 1-4 A woven bag folding device, comprising:
[0030] substrate1;
[0031] Two sets of placement plates 2 are fixedly installed on the top of the substrate 1. The placement plates 2 are fixedly connected to the top of the substrate 1 by two sets of support legs 3. A clamping plate 4 is fixedly connected between the two sets of placement plates 2. A drive motor 6 is fixedly installed on the top of the substrate 1 corresponding to the outside of the clamping plate 4.
[0032] Synchronous roller 5 is rotatably mounted on clamp plate 4. Two sets of rotating discs 7 are sleeved on the outer wall of synchronous roller 5. Folding rods 9 are fixedly connected to the outer wall of both sets of rotating discs 7. Mounting brackets 11 are fixedly installed on the top of both sets of folding rods 9.
[0033] An adjustable distance assembly is provided between the folding rod 9 and the mounting bracket 11.
[0034] Both ends of the synchronizing roller 5 extend out of both ends of the clamping plate 4, and the two sets of rotating disks 7 are fixedly connected to both ends of the synchronizing roller 5 respectively.
[0035] The output shaft of the drive motor 6 is fixedly connected to the outer side of one of the rotating disks 7 at the corresponding center position.
[0036] The top of both sets of placement plates 2 is provided with several sets of grooves 8 that are evenly spaced.
[0037] Both sets of folding rods 9 have openings 16 that pass through both sides of the folding rods 9. A folding plate 10 is slidably installed between the two sets of openings 16. Both ends of the folding plate 10 are fixedly connected to end caps 17.
[0038] The top of the folding plate 10 is provided with square grooves 19 near both ends. A cover plate 20 is slidably installed in the square groove 19. An iron block 22 is fixedly connected to one side of the inner wall of the square groove 19. A magnet 21 that magnetically attracts the iron block 22 is fixedly connected to one side of the cover plate 20 corresponding to the iron block 22.
[0039] The cover plate 20 is inverted L-shaped. When folding and turning the woven bag, the woven bag is easy to fall off, affecting the folding effect. This device has a cover plate 20 on the top of the folding rod 10. By pushing the cover plate 20, it slides in the square groove 19 on the top of the folding plate 10, and is magnetically attached to the iron block 22 by the magnet 21, covering the surface of the woven bag, effectively preventing the woven bag from falling off when folding and turning, and ensuring the smooth progress of the folding process.
[0040] The adjustable distance assembly includes an adjusting rod 12, an assembly plate 13, a return spring 14, and a fixed shaft 15. The top of the mounting bracket 11 is slidably mounted with an adjusting rod 12 extending out of the bottom of the mounting bracket 11 at the middle position. The bottom end of the adjusting rod 12 is fixedly connected to the assembly plate 13 between the inner walls of the two sides of the mounting bracket 11. Several sets of fixed shafts 15 are fixedly connected to the bottom of the assembly plate 13.
[0041] The distance between two adjacent fixed shafts 15 is equal to the distance between two adjacent grooves 8.
[0042] The distance adjustment assembly also includes a fixing groove 18. Two sets of fixing grooves 18 are provided on the top of the folding plate 10. The two sets of fixing grooves 18 are respectively provided between the end cap 17 and the cover plate 20.
[0043] The bottom ends of several sets of fixed shafts 15 slide into the opening groove 16 and slide into the fixed circular groove 18.
[0044] The width of the folded plate 10 is less than the width of the groove 8.
[0045] Working principle: In use, first, place the woven bag to be folded on the surface of the two sets of placement plates 2 and cover the two sets of placement plates 2, aligning the two sides of the woven bag with the two sides of the two sets of placement plates 2. Push the two sets of cover plates 20, causing the cover plates 20 to slide in the square groove 19 and magnetically attach to the iron block 22 through the magnet 21. The two sets of cover plates 20 cover the surface of the woven bag, preventing the woven bag from falling off when folded and flipped. Then, start the drive motor 6, and use the output shaft of the drive motor 6 to drive one of the rotating disks 7 to rotate. 7. The drive motor 6 rotates on the clamping plate 4, driving another set of rotating disks 7 to rotate synchronously. The two sets of folding rods 9 drive the folding plate 10 to slide out of the groove 8 through the rotation of the rotating disk 7 with the rotating disk 7 as the center. When the folding rod 9 drives the folding plate 10 to rotate 180 degrees, the folding plate 10 rotates from the groove 8 on one set of placement plates 2 to the groove 8 on the other set of placement plates 2, thereby folding the woven bag in half. After folding, the two sets of cover plates 20 are pushed outward in the square groove 19, so that the magnet 21 separates from the iron block 22, and the cover plate 20 is separated from the woven bag.
[0046] When folding woven bags of different lengths, the following steps are taken: Pull the two sets of adjusting rods 12 upwards, causing the component plate 13 to pull several sets of fixed shafts 15 upwards. The fixed shafts 15 slide out of the top of the folding rod 9. According to the length of the woven bag, push the folding plate 10 in the two sets of opening slots 16 to align the folding plate 10 with one end of the woven bag. Then, release the adjusting rods 12, and push the component plate 13 downwards through the rebound force of the return spring 14. During the downward sliding process, the component plate 13 slides into the folding rod 9 and inserts into the fixed circular slot 18 where the folding plate 10 stops, thus fixing the position of the folding plate 10.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
