For ease of movement, the bottom of the frame 1 is equipped with four movable pulleys 13 and four adjusting bases 14 threadedly connected. The frame 1 has a first working station, a second working station, a third working station, and a feeding station arranged in a ring. The frame 1 also has an indexing turntable mechanism 2 that sequentially transports the paper towels from the first working station to the second working station, the third working station, and the feeding station. The indexing turntable mechanism 2 has four pressing mechanisms 3 arranged in a ring. The first station is equipped with a first folding component 4 for folding the tissue paper according to the first folding line, the second station is equipped with a second folding component 5 for folding the tissue paper according to the second folding line, and the third station is equipped with a third folding component 6 for folding the tissue paper according to the third folding line. In order to facilitate rotation, the indexing turntable mechanism 2 includes a reduction motor 201 and an indexing turntable 202. The reduction motor 201 is fixed on the frame 1, and the output shaft of the reduction motor 201 is connected to the indexing turntable 202.

[0034] like Figure 5 , Figure 6As shown, to improve the clamping effect during folding, the clamping mechanism 3 includes a positioning bracket 301, an upper flipping cylinder 302, a lower flipping cylinder 303, an upper pressure bar 304, and a lower pressure bar 305. The positioning bracket 301 is fixed on the indexing turntable 202, and the positioning bracket 301 includes two mirror-arranged L7-shaped brackets 3011. Each L7-shaped bracket 3011 has a guide rail 309 on its inner side, and a slider 306 is slidably connected to each guide rail 309. A sliding plate 307 is provided between the two sliders 306, and a mounting base 310 is provided on the sliding plate 307. The upper flipping cylinder 304 is provided on both sides of the mounting base 310. In this embodiment, the bottoms of both the upper and lower tilting cylinders 302 and 303 are fixed to the slide plate 307, and their outer sides are respectively fixed to the corresponding sliders 306. This forms a sliding connection between the sliders 306 and the guide rail 309. To facilitate the movement of the sliders 306, both sides of the sliders 306 are movably sleeved on the outside of the 7-shaped bracket 3011. The output shaft of the upper tilting cylinder 302 passes through one side of the mounting base 310 and is connected to an upper tilting rod 308. An upper pressure strip 304 is provided on the upper tilting rod 308. The output shaft of the lower tilting cylinder 303 passes through... A lower flip rod 311 is connected to one side of the mounting base 310. A lower pressure bar 305 is provided below the lower flip rod 311 and is located above the upper pressure bar 304. The upper pressure bar 304 and the lower pressure bar 305 cooperate to clamp the paper towel. Two adjusting rods 312 are provided at the bottom of the slider 306. A lifting cylinder 313 is provided in the frame 1 to ensure that it is aligned with the corresponding adjusting rod 312 after the indexing turntable 202 is rotated to the correct position. The piston rod of the lifting cylinder 313 is used to raise and lower the adjusting rod 312 after it is aligned with the adjusting rod 312. During operation, the indexing turntable 202 is rotated by the reduction motor 201, ensuring that each group of... After the pressing mechanism 3 rotates to the corresponding station, the reduction motor 201 stops working. At this time, the robot places an uncrushed tissue at the first station and then drives the lifting cylinder 313 on the first station to work, causing the slider 306 to move down. The lower pressure bar 305 presses down the tissue at the first station. At this time, the upper pressure bar 304 on the first station is in an upward flipping state. Then, the first folding component 4 on the first station folds the tissue along the first folding line 15 and drives the upper flipping cylinder 302 to work, so that the originally flipped upper pressure bar 304 flips over and presses down the bent tissue. As the reduction motor 201 continues to work, it transports the bent tissue from the first station to the second station for a second folding.

The specific working principle of the first folding assembly 4 is as follows: The robot places an uncrushed tissue on the mounting plate 405 (and after placing the tissue, the thickness of the tissue drives the cylinder 404 to work, thereby adjusting the height of the mounting plate 405, so that the lower pressure bar 305 can press the tissue onto the mounting plate 405). Then, the robot drives the lifting cylinder 313 on the first station to work, causing the slider 306 to move down, using the lower pressure bar 305 to press the tissue on the mounting plate 405. At this time, the upper pressure bar 304 on the first station is in an upward flipping state. Then, the robot drives the cylinder 402 to work, lifting the diameter part exposed on the mounting plate 405. Then, the robot drives the cylinder 404 to work, pushing the folding plate 406 to move horizontally, folding the lifted diameter part above the upper pressure bar 304, and finally folding it according to the...

[0039] In order to achieve the guiding function, a limiting guide plate 7 with a height higher than the mounting plate 406 is provided on one side of the mounting plate, and a limiting guide plate 8 with a height higher than the mounting plate 516 is provided on the side of the horizontal plate 513 with a height higher than the mounting plate 516.

[0040] The specific working principle of this structure is as follows:

[0041] The robot places an uncrushed tissue on mounting plate 405 (and after placing the tissue, the thickness of the tissue drives cylinder 404 to adjust the height of mounting plate 405, thus facilitating the lower pressure bar 305 to press the tissue firmly onto mounting plate 405). Then, it drives lifting cylinder 313 at the first station to move slider 306 downwards, using the lower pressure bar 305 to press the tissue onto mounting plate 405. At this time, the upper pressure bar 304 at the first station is in an upward-flipping state. Then, it drives cylinder 402 to lift the exposed diameter portion of mounting plate 405, and then drives cylinder 404 to push folding plate 406 horizontally, folding the lifted diameter portion above the upper pressure bar 304, finally forming the desired shape. Figure 1 After the first fold line 15 is folded, the upper pressure strip 304 is driven to flip and press the folded tissue paper to form a compact structure. Figure 1 In the second image, the paper towel, after being folded and pressed at the first station, is rotated to the second station as the indexing turntable mechanism 2 rotates. At the second station, the folded paper towel is placed on the mounting plate 4 516 and the positioning plate 511. After placing the paper towel, the thickness of the paper towel drives the cylinder 6 506 to adjust the height of the positioning plate 511, thus facilitating the lower pressure bar 305 at the second station to press the paper towel between the positioning plate 511 and the mounting plate 4 516. Then, the upper pressure bar 304 at the second station flips upwards and drives the cylinder 8 508 to position the paper towel using the positioning pin 510. Then, the cylinder 7 507 is driven to move the folding plate 1 514 downwards, pressing down on the paper towel to create a crease. Figure 1 The second fold line 16 in the middle, cylinder seven 507 resets, then drives cylinder four 504 to work, moving horizontal plate three 513 to its position, then drives cylinder five 505 to work, finally driving folding plate three 509 to move horizontally and move the side of the paper towel upwards, at the same time allowing positioning post 510 to reset and disengage from the paper towel, finally forming Figure 1 In the state shown in the third picture, the upper pressure bar 304 on the second station is driven to flip down and press the folded paper towel. As the indexing turntable mechanism 2 rotates, the paper towel with the folded edge pressed at the second station is rotated to the third station. At the third station, the folded paper towel is first placed on the mounting plate 3 612. Then, one of the cylinders 14 610 near the horizontal plate 4 614 is driven to work, which drives the folding plate 2 617 to move down and press one side of the paper towel out. Figure 1 The fold line 17 in the middle drives the cylinder 12 608 to work, moving the horizontal plate 4 614 upward, while simultaneously driving the folding plate 2 617 to slowly return to its original position to avoid affecting the upward folding of the tissue paper. Finally, the tissue paper is folded upward along the third fold line 17, forming... Figure 1 The fourth image shows the state of the paper towel. Then, cylinder 13 (609) is driven to work, causing folding plate 6 (616) to press the top of the paper towel firmly. Next, cylinder 14 (610), located away from horizontal plate 4 (614), is driven to work, causing folding plate 2 (617) to move downwards, pressing out the excess portion of the paper towel after folding it upwards. Figure 1 The fourth fold line 18 is the fold line, then the driving cylinder 11 607 works, the folding plate 5 613 moves horizontally to drive the excess paper towel to bend downwards, and after bending, the driving cylinder 10 606 works to move downwards, so that the horizontal movement of the folding plate 5 613 is not affected, finally forming Figure 1In the state shown in the fifth picture, the upper pressure bar 304 on the third station is driven to flip down and cooperate with the lower pressure bar 30 to press the paper towel. Then, it is driven to the unloading station by the rotation of the indexing turntable mechanism 2 to realize the unloading and packaging. Therefore, this structure can automatically fold the paper towel to form the shape of a baby bag. Then, knives, forks, spoons, etc. are placed inside the paper towel of the baby bag. Therefore, by setting the above structure, the folding dotted lines and creases are pressed out directly according to the requirements, and then the edges are automatically folded, which further improves work efficiency, reduces labor costs, and is less prone to errors.
