The length folding unit 11 is arranged on one side of the cutting unit 10 to further fold the cut paper into the final tissue paper product. The electric control box 2 is electrically connected to each key unit of the device to control and coordinate the work of each unit. The touch screen 15 above the electric control box 2 provides a man-machine interaction interface, enabling operators to conveniently set and monitor the working state of the equipment. The indicator light 7 provided at the top of the embossing unit 5 is used to indicate the operating state of the equipment or give a warning when a failure occurs.

[0026] The unwinding unit 3 includes a driving motor 22 and a central shaft 18, and its main function is to control the unwinding of the raw paper roll. The driving motor 22 is connected to the central shaft 18 through a speed reducer to ensure the stable rotation speed of the central shaft 18 and suitable for processing requirements. The central shaft 18 is nested inside the unwinding roller 19, enabling the unwinding roller 19 to rotate smoothly, thereby smoothly unwinding the paper roll. One end of the unwinding roller 19 close to the driving motor 22 is provided with a fixed flange 20 for firmly fixing the unwinding roller 19 on the central shaft 18 to ensure no displacement during the paper roll unwinding process. An adjusting handwheel 23 is arranged at the end of the unwinding roller 19. By adjusting the adjusting handwheel 23, it is convenient for the operator to align the center of the unwinding roller 19 with the center of the embossing roller of the pressing roller unit. A movable flange 21 is arranged between the fixed flange 20 and the adjusting handwheel 23, and the function of the movable flange 21 is to provide a certain degree of flexibility to meet the sizes of different paper rolls.

[0027] In addition, a film storage unit 4 is provided below the unwinding unit 3 for storing the paper released during the unwinding process. The film storage unit 4 includes a swing arm 24, and an angle sensing element 26 is connected to one end of the swing arm 24. This sensing element can monitor the angle change of the swing arm 24 in real time to ensure the stable operation of the storage unit. A floating roller 25 is provided at the other end of the swing arm 24. The floating roller 25 can move up and down as the paper unfolds, playing a buffering role to prevent uneven tension or breakage of the paper during the unfolding process. Through these designs, the unwinding unit 3 and the film storage unit 4 work together to ensure that the paper roll can be unwound at a stable speed and with appropriate tension, laying a good foundation for subsequent processing steps.

[0028] The width folding unit 6 is one of the core parts of the device and is responsible for precisely folding the paper towels to the width required by the customer. The unit includes a width folding frame 27, which is the support frame of the entire folding mechanism and provides a stable working environment for the folding plates. A first folding plate 28, a second folding plate 29, and a third folding plate 30 are installed on the width folding frame 27. These three folding plates are fixed to the width folding frame 27 in a sliding connection manner, allowing their positions to be adjusted according to requirements during operation.

[0029] Each folding plate is composed of a front plate and a rear plate, and the distance between the front and rear plates can be precisely adjusted by a star handle 31. The purpose of the adjustment is to adapt to the folding requirements of paper towels of different specifications and ensure the accuracy and consistency of the folding process. A scale 8 is provided on one side of each of the front and rear plates. These scales can help the operator adjust the distance between the folding plates, so that the folding width of the paper towels meets the predetermined requirements. Through this structural design, the width folding unit 6 can accurately fold the width of the paper towels according to different specification requirements during the production process of the paper towels, providing a high-quality basis for subsequent cutting and length folding processes. The folding plates can be replaced according to the number of folding times. Three layers of folding plates are set to make the paper towel folding speed faster and more stable.

[0030] The embossing unit 5 is an important part of the paper towel forming and cutting device and is responsible for pressing delicate patterns or textures on the surface of the paper towels. The unit consists of multiple key components, including a lower embossing roller 33, an upper pressing roller 34, and a transition roller 35, which are firmly installed on the left and right wallboards 32 of the embossing unit 5 body through bearings. The lower embossing roller 33 is a roller specially designed to press patterns on the paper towels, and its surface may be engraved with various designed patterns or textures. When the paper towel passes between the rollers, the lower embossing roller 33 imprints these patterns on the paper towel. The upper pressing roller 34 is located above the lower embossing roller 33 and mainly plays a role in applying pressure to ensure that the paper towel is in close contact with the lower embossing roller 33 so that the embossing process can proceed smoothly. The transition roller 35 plays a role in smoothly conveying the paper towel, keeping the paper towel flat and continuously moving during the embossing process.

[0031] In order to ensure the safety of operation, a safety cover 36 is provided on the outside of the embossing unit 5 body, which can not only prevent the operator from contacting the high-speed rotating roller, but also prevent paper towels or other objects from being accidentally drawn into the machine, thereby effectively reducing safety hazards in the production process.

[0032] The length folding unit 11 and the cutting unit 10 are linked by a gear box 17 to ensure that the paper towel can be synchronously folded into the required length specification after being cut. A driving motor is arranged in the gear box 17. The length folding unit 11 includes a folding plate 41, which is mounted on a guide rail slider 40 and can slide smoothly along the guide rail. The guide rail slider 40 is connected to the turntable 37 by a connecting rod 39. The design of the connecting rod 39 ensures the precise movement of the folding plate 41, so that the paper towel can be folded evenly and accurately after being cut.

[0033] As a key component of power transmission, the turntable 37 is firmly connected to the transmission shaft of the gearbox 17 through the locking sleeve 38. The locking sleeve 38 can be connected to the turntable 37 at any angle to facilitate the adjustment of the folding center position. When the gearbox 17 is started, the transmission shaft drives the turntable 37 to rotate, and then drives the folding plate 41 to move along the guide slider 40 through the connecting rod 39 to achieve the length folding of the paper towel. Through precise mechanical linkage, the length folding unit 11 can work in coordination with the cutting unit 10 to ensure that the folding and cutting processes of the paper towel are highly synchronized, thereby improving production efficiency and product consistency.

[0034] One side of the length folding unit 11 is equipped with a conveying unit 12, whose main function is to stably convey the folded paper towels to the next processing step. The conveying unit 12 is composed of a driving shaft 42 and a driven wheel 44, which are tightly connected by a conveyor belt 43 to form a continuous conveying system. The driving shaft 42 is responsible for driving the conveyor belt 43 to operate and smoothly convey the folded paper towels, while the driven wheel 44 ensures that the tension of the conveyor belt 43 is appropriate, thereby maintaining the stability of the conveying process.

[0035] Above the length folding unit 11, a cutting unit 10 is installed, which is used to accurately cut the folded paper towels according to the specified length. A sharp blade 46 is installed on the blade shaft 45 in the cutting unit 10, which cuts the paper towels by rotation. In order to ensure the safety of operation, a protective cover 14 is designed on the outside of the cutting unit 10 to prevent the operator from accidentally touching the blade 46. The protective cover 14 is also equipped with an induction switch 47. If the protective cover 14 is opened during normal operation of the device, the induction switch 47 will be triggered and feedback an electrical signal to the electric control box 2, immediately stopping the operation of the cutting unit 10, thereby ensuring the safety and efficient operation of the equipment.

[0036] The traction unit 9 is located above the cutting unit 10 and is responsible for conveying the paper towels after passing through the length folding unit 11 to the cutting unit 10. The traction unit 9 consists of several groups of traction rollers 48 and pressure rollers 49. The traction rollers 48 are responsible for pushing the paper towels forward, while the pressure rollers 49 maintain the flatness and smoothness of the paper towels by applying appropriate pressure. To adapt to paper towels of different thicknesses and materials, the pressure roller 49 is connected to the adjustment handle 51 through a spring 50. The adjustment handle 51 can adjust the pressure of the pressure roller 49 as needed to ensure that the paper towels do not wrinkle or shift during traction.

[0037] To eliminate the static electricity that may be generated during the transmission of the paper towels, an electrostatic eliminator 52 is installed behind the rotation direction of each group of traction rollers 48 and pressure rollers 49. The electrostatic eliminator 52 neutralizes the static electricity on the surface of the paper towels by releasing charges, preventing the paper towels from sticking or curling due to static electricity during transmission, thereby improving the processing efficiency and the quality of the finished products.

[0038] The operating principle of this device is as follows: Through the coordinated work of a series of precise mechanical units, the roll of paper towels is processed into finished products of the specifications required by customers. The core of the device includes multiple key units such as unwinding, embossing, folding, cutting, traction, and conveying, each undertaking different functions.

[0039] First of all, the unwinding unit 3 unfolds the raw paper roll to provide uniform tension for subsequent processing. The unfolded paper enters the embossing unit 5, and a delicate pattern is pressed on the surface of the paper through the cooperation of the upper and lower rollers. Then, the paper enters the width folding unit 6, and after being folded by three layers of width folding plates, the very wide paper towels are folded into multi-layer paper towels of the desired width.

[0040] After that, the traction unit 9 conveys the paper stably to the cutting unit 10, ensuring that the paper enters the cutting process at an appropriate speed and tension. The cutting unit 10 cuts the paper into segments of the specified length through precise blades, and further folds the cut paper into the final finished product through the linked length folding unit 11.

[0041] The transmission and actions between each unit are uniformly coordinated and controlled by the electric control box 2 to ensure the efficient and safe operation of the device. The touch screen 15 in the device provides an intuitive operation interface for the operator, facilitating the setting and monitoring of the equipment. The indicator lights 7 on the embossing unit 5 and the protective covers 14 on the cutting unit 10 ensure the safety of the production process.

[0042] Through the precise cooperation of each unit, the device can efficiently and accurately complete the processing and cutting tasks of the paper towels, meeting the needs of different customers.
