[0026] A folding assembly 11 is provided on the frame 1 located between two adjacent feeding mechanisms 5. The folding assembly 11 includes a mounting frame 12 fixedly mounted on the top of the frame 1. The mounting frame 12 is door-shaped. The lower ends of the two vertical arms of the mounting frame 12 are respectively fixedly mounted on the top of the corresponding side panels 3 by bolts.
[0027] like Figure 4 As shown, three first rotating shafts 13 extending horizontally are rotatably mounted on the mounting frame 12. The first rotating shafts 13 extend forward and backward perpendicularly to the conveying direction of the feeding mechanism 5. The three first rotating shafts 13 are distributed in a right triangle. The three first rotating shafts 13 are respectively a top rotating shaft 14 located at the top of the right triangle, a first bottom rotating shaft 15 located directly below the top rotating shaft 14, and a second bottom rotating shaft 16 located on the horizontal side of the first bottom rotating shaft 15. The second bottom rotating shaft 16 is located downstream of the first bottom rotating shaft 15 along the conveying direction of the feeding mechanism 5. A first conveyor belt 17 is sleeved on the outer side of the three first rotating shafts 13. The first conveyor belt 17 is provided with a vertically extending feeding section 18 located between the top rotating shaft 14 and the first bottom rotating shaft 15. The first conveyor belt is also provided with a discharging section 19 located between the top rotating shaft 14 and the second bottom rotating shaft 16. One end of the discharging section 19 is connected to the upper end of the feeding section 18, and the other end extends obliquely downward.
[0028] Two second rotating shafts 20 are also rotatably mounted on the mounting frame 12. The second rotating shafts 20 are arranged parallel to the first rotating shaft 13. A second conveyor belt 21 is sleeved on the outer sides of the two second rotating shafts 20. The two second rotating shafts 20 are respectively a low rotating shaft 22 and a high rotating shaft 23. The low rotating shaft 22 is located on the horizontal side of the first bottom rotating shaft 15, and the low rotating shaft 22 is located upstream of the first bottom rotating shaft 15 along the conveying direction of the feeding mechanism 5. The high rotating shaft 23 is located obliquely above the top rotating shaft 14, and the high rotating shaft 23 is located downstream of the top rotating shaft 14 along the conveying direction of the feeding mechanism 5. A folding channel 41 is provided between one side of the lower end of the second conveyor belt 21 and the feeding section 18 of the first conveyor belt 17, and one side of the upper end of the second conveyor belt 21 bypasses the upper direction of the top rotating shaft 14 and extends to the right downstream along the conveying direction of the feeding mechanism 5, and the second conveyor belt 21 presses the first conveyor belt 17 located at the top of the top rotating shaft 14, so that the folding channel 41 gradually narrows from bottom to top, thereby improving the folding effect of the towels.
[0029] like Figure 2 As shown, one of the first rotating shafts 13 is connected to one of the second rotating shafts 20 by a pair of mutually meshing gears 24, and one of the first rotating shafts 13 is driven to rotate by a second motor 25, and the second motor 25 is installed on the top of the mounting frame 12 by bolts, and the end of the corresponding first rotating shaft 13 is fixedly connected to the rotating shaft of the second motor 25 by a third belt 44. When the towel is rushed into the folding channel 41 between the first conveyor belt 17 and the second conveyor belt 21, the first rotating shaft 13 is driven by the second motor 25 to rotate clockwise, and then the first rotating shaft 13 drives the first conveyor belt 17 to rotate clockwise; at the same time, the first rotating shaft 13 drives the second rotating shaft 20 to rotate counterclockwise, and then the second rotating shaft 20 drives the second conveyor belt 21 to rotate counterclockwise, and the towel is driven to move upward along the feeding section 18 of the first conveyor belt 17 through the first conveyor belt 17 and the second conveyor belt 21; because the second conveyor belt 21 presses the first conveyor belt 17 located at the top of the top rotating shaft 14, the towel in the folding channel 41 can follow the first conveyor belt 17 and the second conveyor belt 21 to bypass the top rotating shaft 14 and move to the discharge section 19 of the first conveyor belt 17, and the towel that has been folded once is re-conveyed to the feeding mechanism 5 through the discharge section 19 of the first conveyor belt 17, and the folded towel continues to be conveyed to the next folding component 11 through the feeding mechanism 5.
[0030] like Figure 4 and Figure 5As shown, a vertically extending slide bar 26 is fixedly installed on the inner side of the top of the mounting frame 12, and the upper end of the slide bar 26 is threadedly connected to the mounting frame 12. A mounting plate 27 is slidably installed on the slide bar 26. Two vertical plates 28 arranged opposite to each other in front and back are fixedly installed on the bottom of the mounting plate 27 by bolts. A tensioning roller 29 arranged parallel to the second rotating shaft 20 is rotatably installed between the two vertical plates 28. The tensioning roller 29 is located above the low-position rotating shaft 22. The tensioning roller 29 is supported on the inner side of the second conveyor belt 21. A stopper 30 for preventing the mounting plate 27 from falling off is welded to the lower end of the slide bar 26, and a spring 31 for driving the tensioning roller 29 to tension the second conveyor belt 21 is connected between the stopper 30 and the mounting plate 27. The spring 31 is sleeved on the slide bar 26. By setting a tensioning roller, the width of the folding channel 41 and the distance between the first conveyor belt 17 and the second conveyor belt 21 located at the top rotating shaft 14 can be adaptively changed according to the thickness of the towel, so that towels of different thicknesses can pass smoothly between the first conveyor belt 17 and the second conveyor belt 21.
[0031] like Figure 4 and Figure 6 As shown, the frame 1 is also provided with a punching plate 42 for punching the towels upward into the folding channel 41, and the punching plate 42 corresponds to the folding assembly 11. A fixed plate 32 is fixedly installed on the frame 1 located below two adjacent feeding mechanisms 5, and the two ends of the fixed plate 32 are fixedly connected to the two side plates 3 by bolts, respectively. A movable plate 34 driven to rise and fall by a cylinder 33 is provided above the fixed plate 32, and a vertically extending sliding column 35 is fixedly installed at the bottom of the movable plate 34 by bolts. The sliding column 35 is slidably installed on the fixed plate 32, which can support and guide the movable plate 34; the cylinder body of the cylinder 33 is fixedly installed on the fixed plate 32 by bolts, and the piston rod of the cylinder 33 passes through the fixed plate 32 upward and is fixedly installed at the bottom of the movable plate 34 by bolts; the top of the movable plate 34 is fixedly installed with a punching plate 42 by bolts, and the projection of the punching plate 42 in the vertical direction is located between the corresponding two feeding mechanisms 5.
[0032] like Figure 4 and Figure 7As shown, an adjustment plate 43 is provided on the frame 1 downstream of each punching plate 42. The adjustment plate 43 is driven by an adjustment mechanism and moves left and right along the conveying direction of the feeding mechanism 5. A photoelectric sensor 36 for detecting the position of the towel is installed on the top of the adjustment plate 43. The photoelectric sensor 36 is located between two adjacent conveyor belts 7. Specifically, the inner sides of the two side plates 3 corresponding to the front and rear end positions of the adjustment plate 43 are respectively fixed with installation boxes 37 by bolts, and the two installation boxes 37 are opened on opposite sides. A guide rod 38 extending left and right along the conveying direction of the feeding mechanism 5 is fixedly installed in one of the installation boxes 37 by bolts, and one end of the adjustment plate 43 is slidably installed on the guide rod 38; a third motor 39 is installed in the other installation box 37 by bolts, and a screw rod 40 is coaxially fixedly installed on the rotating shaft of the third motor 39 through a coupling, the screw rod 40 is arranged parallel to the guide rod 38, and one end of the screw rod 40 away from the third motor 39 is rotatably installed on the inner wall of the installation box 37 through a bearing, and one end of the adjustment plate 43 away from the guide rod 38 is threadedly connected to the screw rod 40.
[0033] The photoelectric sensor 36 is a diffuse reflection photoelectric sensor. The third motor 39 drives the screw rod 40 to rotate, and then the screw rod 40 drives the adjustment plate 43 to move left and right along the guide rod 38, so as to adjust the distance between the photoelectric sensor 36 and the punch plate 42 located upstream thereof according to the length of the towel or the folded towel, so as to achieve the center folding of the towel. Specifically, after the photoelectric sensor 36 is turned on, when the towel moves between the two feeding mechanisms 5 and one end of the towel covers the top of the photoelectric sensor 36, the photoelectric sensor 36 recognizes that the towel is in place, and then the controller drives the cylinder 33 to perform a telescopic movement; when the cylinder 33 extends, it drives the punch plate 42 to punch the towel upward into the corresponding folding channel 41 between the two feeding mechanisms 5, completing a folding action; after the folding is completed, the cylinder 33 contracts and drives the punch plate 42 to move to the bottom of the feeding mechanism 5 to reset.
[0034] In specific use, when the photoelectric sensor 36 is in the off state, when the towel covers the top of the photoelectric sensor 36, the corresponding cylinder 33 will not drive the punch plate 42 to move, so that the towel will not be folded. Therefore, according to the demand for the number of towel folding times, the corresponding number of photoelectric sensors 36 are turned on, and according to the length of the towel or the length of the folded towel, the distance between the turned-on photoelectric sensor 36 and the punch plate 42 located upstream thereof is adjusted, so as to achieve different numbers of folding of the towel.
