The cutting conveyor belt 55 is arranged on the other side of the cutting knife 53. The fixing plate 54 is arranged on the upper and lower sides of the cutting knife 53 to fix the movement trajectory of the cutting knife 53. The stacking component 4 includes a stacking cylinder 41, an opening and closing support platform 42, an opening and closing cylinder 43 and a pressing plate 44. The stacking cylinder 41 is driven to connect the pressing plate 44 at the bottom. The stacking cylinder 41 is arranged above the cutting conveyor belt 55, and the opening and closing support platform 42 is arranged below the cutting conveyor belt 55. The opening and closing cylinder 43 is arranged above the cotton towel conveyor belt 3, and is arranged on both sides of the opening and closing support platform 42 to drive the opening and closing of the opening and closing support platform 42; the cutting conveyor belt 55 includes a first conveyor belt 551 and a second conveyor belt 552, the first conveyor belt 551 is arranged above the second conveyor belt 552, the first conveyor belt 551 includes two first conveyor rollers 553 arranged at intervals and two first spacing belts 554 wound around the outside of the two first conveyor rollers 553, the second conveyor belt 552 includes two second conveyor rollers 555 arranged at intervals, two second spacing belts 556 wound around the outside of the two second conveyor rollers 555, and two third conveyor rollers 557 for reducing the upper and lower distances between the two second spacing belts 556;

[0032] The two first spacing belts 554 are arranged at intervals, the width of the pressing plate 44 is less than or equal to the interval between the two first spacing belts 554, the two second spacing belts 556 are arranged at intervals, and the interval distance between them is consistent with the interval distance between the two first spacing belts 554, the two third conveying rollers 557 are arranged below the two second spacing belts 556, and the top height of the two third conveying rollers 557 is higher than the bottom height of the two second conveying rollers 555;

[0033] The folding head 12 includes a U-shaped frame 121, a folding plate 122 and a folding rod 123, wherein the folding plate 122 and the folding rod 123 are arranged on the side of the U-shaped frame 121 close to the cotton towel conveyor belt 3, and the side of the U-shaped frame 121 close to the cotton towel conveyor belt 3 is provided with an inclined opening 124, the folding plates 122 are arranged on both sides of the inclined opening 124, and the folding rod 123 is arranged at the bottom of the inclined opening 124;

A pressing block 173 is arranged on the outer side of the pressing roller 171. The pressing block 173 presses the upper and lower sides of the cotton soft towel package and cooperates with the heat-sealing roller 172 to achieve sealing. Since the pressing block 173 protrudes from the outer surface of the pressing roller and contacts, in actual operation, the stacked cotton soft towels pass through the heat-sealing roller group 17 in the area where the pressing block 173 is not arranged on the pressing roller 171, and the cotton soft towels will not be squeezed;

[0036] How it works:

[0037] When started, the turntable 51 is driven by an external motor to rotate, driving the cutting knife 53 to move back and forth in and out between the first conveyor belt 551 and the second conveyor belt 552. When the cutting knife enters between the first conveyor belt 551 and the second conveyor belt 552, part of the cotton towel roll at the end is brought in and cut. When the cutting knife exits between the first conveyor belt 551 and the second conveyor belt 552, the friction between the cotton towel and the second spacing belt 556 is greater than the friction between the cotton towel and the cutting knife 53. After the cutting knife 53 exits, the cotton towel is sent to the cutting conveyor belt 551. To the bottom of the stacking cylinder 41, the stacking cylinder 41 is started to press the cut cotton towel down and drop it onto the opening and closing support platform 42. After the cotton towels on the opening and closing support platform 42 are stacked to a set number of sheets, the opening and closing cylinder 43 is started to drive the opening and closing support platform 42 to open, so that the stacked cotton towels fall onto the cotton towel conveyor belt 3 and are conveyed to the packaging bag 13 in the folding head 12. Under the cooperation of the pressing wheel group 14 and the heat-sealing wheel group 15, the packaging bag 13 is heat-sealed into a ring shape. After the thickness is unified by the pressing conveyor belt 16, the packaging bag 13 is sealed under the action of the heat-sealing roller group 17.
