[0002] Non-woven fabrics, also known as nonwovens, are made of oriented or random fibers and are a new generation of environmentally friendly materials. They are popular among the public due to their moisture-proof, breathable, flexible, lightweight, non-combustible, easily decomposable, non-toxic and non-irritating, rich colors, low price, and recyclability. The production process of non-woven fabrics is currently semi-mechanical and semi-manual. The folding process of non-woven fabrics can now be automated through machinery. Folding rollers play a key role in the non-woven fabric folding device, guiding, folding, and compacting the non-woven fabric through rotation and coordination.

It should be understood that the specific examples described herein are merely illustrative of the present invention and are not intended to limit the present invention. Directional terms such as up, down, left, right, front, or back, mentioned in the following embodiments, are merely references to the directions in the accompanying drawings. Therefore, the directional terms used are intended to illustrate and not to limit the present invention. Furthermore, throughout the embodiments, the same reference numerals represent the same elements.

[0020] like Figure 1 、 Figure 2 、 Figure 3 The nonwoven fabric folding device shown comprises a frame 1 , one side of which is rotatably connected to a discharge shaft 2 , on which a nonwoven fabric mother roll 3 is wound.

[0021] Axle plates 4 are fixedly connected to both ends of the frame 1 near the discharge shaft 2. A belt roller 5 is fixedly connected to the top between the two shaft plates 4, and a pulley 6 is fixedly connected to the middle of the belt roller 5. A belt 7 is fixed to one end of the pulley 6. The belt 7 passes over the non-woven fabric mother roll 3 and is in constant contact with the non-woven fabric mother roll 3 for flexible cooperation. A counterweight block 8 is fixedly connected to the end of the belt 7 vertically downward.

[0022] The middle part between the two shaft plates 4 is rotatably connected to the first cloth guide roller 9, and the lower part of the shaft plate 4 is rotatably connected to the second cloth guide roller 10 and the third cloth guide roller 11. The second cloth guide roller 10 and the third cloth guide roller 11 are both located at the same horizontal height and are arranged side by side. The second cloth guide roller 10 is located on the side close to the unloading shaft 2, and the third cloth guide roller 11 is located on the side away from the unloading shaft 2.

[0023] As a further illustration of this example, since the counterweight 8 has a certain gravity, the belt 7 will press the non-woven fabric mother roll 3 so that the non-woven fabric mother roll 3 always maintains a certain tension.

[0024] A first folding device is fixedly connected to the frame 1 on the side of the shaft plate 4 away from the discharge shaft 2. The first folding device includes a base plate 12, which is trapezoidal in shape. Supports 13 are provided at the four corners of the base plate 12. The top of the support 13 is fixedly connected to the base plate 12, and the bottom of the support 13 is fixedly connected to the frame 1. A rotating shaft seat 14 is fixedly connected to both ends of the base plate 12 on the side close to the shaft plate 4. A rotating shaft 15 is rotatably connected between the two rotating shaft seats 14. A guide plate 16 is fixed to the rotating shaft 15 on the side close to the mounting plate. The guide plate 16 is in the shape of a triangle. One side of the guide plate 16 is bent downward at a certain arc. The bend of the guide plate 16 fits with the rotating shaft 15 and is fixed by welding. The bottom of the guide plate 16 is abutted against a vertical shaft 17. The lower part of the vertical shaft 17 passes through the base plate 12 and is movably connected to the base plate 12. A thread is provided at the lower portion of the vertical shaft 17 , and the vertical shaft 17 is fixed to the base plate 12 by fastening bolts on the upper and lower sides of the base plate 12 .

[0025] As a further illustration of this example, the height and the angle of the guide plate 16 with the horizontal plane can be fixed by a fixed vertical shaft 17. When the height and the angle of the guide plate 16 with the horizontal plane need to be adjusted, the fastening bolts of the vertical shaft 17 are loosened, and then the height of the vertical shaft 17 exposed above the base plate 12 is adjusted. As the height of the vertical shaft 17 is adjusted, the fulcrum of the vertical shaft 17 and the guide plate 16 will change, and the guide plate 16 will rotate with the rotating shaft 15, thereby realizing the adjustment of the height of the guide plate 16 and the angle with the horizontal plane to adapt to non-woven fabrics of different sizes.

[0026] A first guide roller 18 and a second guide roller 19 are provided on the frame 1 of the primary folding device on the side away from the shaft plate 4. The first guide roller 18 and the second guide roller 19 are rotatably connected via a roller shaft.

[0027] A secondary folding mechanism is provided on the side of the frame 1 away from the unwinding shaft 2. This mechanism includes a drive unit located below the frame 1. The drive unit comprises a motor 27, the output of which is connected to the input of a reducer 28. The reducer 28 is fixedly connected to a reducer base 29. Below this base 29 is a trapezoidal slider. The lower portion of this base 29 is movably connected to a tailstock 30, which is fixedly connected to the lower portion of the frame 1. The output of the reducer 28 is fixedly connected to a drive shaft 31, which is arranged in a vertical direction.

[0028] The top of the drive shaft 31 is connected to the bottom of a transmission shaft 34 via a chain coupling 32. There are two transmission shafts 34, both rotatably connected to the frame 1. Adjacent transmission shafts 34 are connected by a transmission gear 33 mounted in the middle of each shaft. The tops of both transmission shafts 34 extend through the frame 1 and are detachably connected to folding rollers 21 via couplings. The folding rollers 21 consist of two vertically mounted pairs of rollers, both rotatably connected to the frame 1.

[0029] The top of the folding roller 21 is detachably fixedly connected to the large pulley shaft 25 through a coupling, and the large pulley shaft 25 is rotatably connected to the top of the frame 1. The folding roller 21 connected to the reducer 28 is fixedly connected to the large pulley shaft 25 connected to the top with a large pulley 24.

[0030] Two feed rollers 20 are installed between the folding roller 21 and the guide roller. These rollers 20 are rotatably connected to the frame 1 in a vertical direction and are arranged in a pair. A small pulley 22 is fixedly connected to the top of one of the feed rollers 20. The small pulley 22 is connected to a large pulley 24 via a belt. A tensioning pulley 23 is also installed between the small pulley 22 and the large pulley 24. The tensioning pulley 23 is rotatably connected to the top of the frame 1. The two small pulleys 22 are connected to each other via a small gear 26 mounted at the bottom of each small pulley 22.

[0031] As a further illustration of this example, when the drive device is activated, the drive shaft 31 rotates, thereby driving the transmission shaft 34 connected to it via a chain coupling 32. The transmission shaft 34 drives another transmission shaft 34 via a transmission gear 33 installed in the middle. Both transmission shafts 34 drive the folding rollers 21 connected to them via couplings. The large pulley 24 installed on the top of one of the folding rollers 21 drives the small pulley 22 connected to it via a belt. The rotation of the small pulley 22 drives the feed roller 20 fixed to it. The other feed roller 20 is connected to it via a small gear 26 and rotates together.

[0032] The working principle and use process of this utility model:

[0033] When the non-woven fabric needs to be folded, the driving device is started, and the non-woven fabric is led out from the discharge shaft 2, and passes through the first guide roller 9, the second guide roller 10, and the third guide roller 11 on the mounting plate in turn, and then passes through the guide plate 16 from the lower side of the guide plate 16 from above the guide plate 16. Since the guide plate 16 is triangular, when the non-woven fabric passes along the guide plate 16, it will pass through both sides of the guide plate 16 at the end of the guide plate 16, thereby realizing a vertical folding. After the non-woven fabric is folded once, it passes through the middle of the first guide roller 18 and the second guide roller 19, and then passes through the middle of the two feeding rollers 20. Finally, it is folded twice by the folding roller 21, thereby completing the folding of the entire non-woven fabric.

[0034] When the size of the non-woven fabric changes, it is necessary to adjust the height of the guide plate 16 accordingly through the vertical shaft 17, and the folding roller 21 also needs to be replaced. First, separate the drive device from the transmission roller by disassembling the chain coupling 32, push the reducer base plate 29, so that the drive device leaves the initial position, and then disassemble the couplings on the upper and lower sides of the folding roller 21, remove the folding roller 21, and then replace it with a folding roller 21 of appropriate size, and then connect the couplings on the upper and lower sides of the folding roller 21, and push the drive device back to its original position, and then connect the drive shaft 31 connected to the drive device with the transmission shaft 34 through the chain coupling 32, and start the device again.

[0035] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above-mentioned implementation measures. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
