Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] In one embodiment of this utility model, such as Figures 1-3 As shown, a roll forming device for producing tissue paper is provided, including a roll forming mechanism 10, a slitting mechanism 20, and a winding mechanism 30. The roll forming mechanism 10 includes a fixed base 11, and an embossing roller assembly 12 and a guide assembly 13 mounted on the fixed base 11. The embossing roller assembly 12 is located at the front end of the guide assembly 13 and is used to roll out patterns on the surface of the tissue paper. The guide assembly 13 is used to guide the rolled tissue paper to the slitting mechanism 20. The slitting mechanism 20 is used to cut the entire conveyed tissue paper. The winding mechanism 30 is located at the end of the slitting mechanism 20 away from the roll forming mechanism 10 and is used to wind up the cut tissue paper.

[0026] Specifically, the core component of the device is the roll forming mechanism 10, which consists of a fixed base 11, an embossing roller assembly 12, and a guide assembly 13. The embossing roller assembly 12 is responsible for applying pressure to the surface of the tissue paper as it passes through, forming the desired pattern. The guide assembly 13 ensures that the paper maintains the correct orientation and position during the roll forming process, allowing it to pass smoothly through the embossing roller assembly 12. The rolled paper is guided to the slitting mechanism 20, which is responsible for cutting the continuous paper into predetermined lengths. This step typically involves one or more rotating blades that cut clean slits in the paper. The slit paper segments are then conveyed to the winding mechanism 30, which winds these segments into rolls for easy storage and transport. The winding mechanism 30 typically includes one or more rolls that can evenly wind the paper, ensuring the rolls are tight and uniform.

[0027] Automated rolling, slitting, and rewinding processes significantly improve the production efficiency of tissue paper, reduce manual intervention, and lower production costs. Automated rolling ensures consistent pattern and quality in every sheet of tissue paper, enhancing product consistency and market competitiveness. The device can adjust the embossing roller assembly 12 according to different design requirements to produce tissue paper with various patterns, meeting diverse market demands. Precise slitting mechanism 20 reduces paper waste and improves material utilization. The rewound paper rolls are easy to store and transport, and also facilitate subsequent packaging and distribution processes.

[0028] In this example, the embossing roller assembly 12 includes a first embossing roller 121, a second embossing roller 122, a drive module, a heating module, and a mounting block 123. Both the first embossing roller 121 and the second embossing roller 122 are mounted on the fixed base 11 via the mounting blocks 123, and both the first embossing roller 121 and the second embossing roller 122 can rotate on their respective mounting blocks 123. Both the first embossing roller 121 and the second embossing roller 122 have patterns on their surfaces, and both are equipped with heating modules. The drive module is mounted on the fixed base 11 and is connected to the first embossing roller 121 and the second embossing roller 122 in a driving connection. Specifically, the first embossing roller 121 and the second embossing roller 122 are arranged sequentially downwards along the height direction of the fixed base 11. The first embossing roller 121 and the second embossing roller 122 are mounted on the fixed base 11 via the mounting blocks 123 and can rotate on the mounting blocks 123. Both embossing rollers have patterns designed on their surfaces, which are transferred onto the paper surface as it passes through. Heating modules are integrated into both the first embossing roller 121 and the second embossing roller 122, ensuring uniform temperature on the roller surfaces. These modules heat the rollers, making it easier for patterns to form on the paper during the rolling process, while also increasing the paper's softness and comfort. A drive module is mounted on the fixed base 11 and is connected to the first embossing roller 121 and the second embossing roller 122. This module provides power to rotate the embossing rollers, thereby rolling the paper. The integrated design of the embossing rollers and heating modules makes maintenance and replacement easier, reducing downtime. The heating modules can be heating wires.

[0029] Furthermore, by using supersonic spraying technology to coat the surface of the embossing roller with a hard alloy material (such as WC-10Co4Cr), a hardened working layer is formed, which significantly improves the hardness, wear resistance, and impact resistance of the embossing roller. The thickness of this hardened working layer can be controlled between 100-500μm, and the bonding strength with the bottom roller is greater than 1MPa, effectively avoiding the problem of stress defects on the surface during the embossing process.

[0030] In this example, the mounting block has a condensate channel within it, and an interface on the mounting block connects to this condensate channel. Specifically, the condensate channel within the mounting block is used for the flow of condensate. This channel design allows condensate to flow inside the mounting block, reducing the heat generated by the heating module during operation and thus extending the lifespan of the mounting block. The interface on the mounting block connects to the condensate channel; this interface can be a pipe, valve, or other connecting device, used to introduce external condensate into the channel or drain condensate from the channel.

[0031] In this example, the fixed base 11 is provided with mounting sliding holes 111, which extend along the height direction of the fixed base 11, and the mounting block 123 is confined within the mounting sliding holes 111. Specifically, the mounting sliding holes 111 on the fixed base 11 are elongated holes for mounting and positioning the mounting block 123. These holes extend along the height direction of the fixed base 11, allowing the mounting block 123 to be adjusted and fixed in the vertical direction. The mounting block 123 is fixed within the mounting sliding holes 111 by limiting structures (such as slots, bolts, wedges, etc.). This design allows the mounting block 123 to move along the sliding hole direction on the fixed base 11 to adjust the position of the embossing roller, while ensuring that the mounting block 123 does not shift during operation. The design of the mounting sliding holes 111 allows the mounting block 123 to be easily adjusted in height on the fixed base 11, facilitating the adjustment of the embossing roller position according to production needs. The design of the mounting sliding holes 111 allows the mounting block 123 to adapt to embossing rollers of different specifications, increasing the flexibility and applicability of the equipment.

[0032] In this example, the guiding assembly 13 includes a first roller 131, a second roller 132, and a traction motor. The first roller 131 and the second roller 132 are arranged vertically opposite each other on a fixed base 11. The traction motor is mounted on the fixed base 11 and is drive-connected to the first roller 131 and the second roller 132. The first roller 131 and the second roller 132 convey tissue paper through rotational compression. Specifically, the first roller 131 and the second roller 132 are arranged vertically opposite each other on the fixed base 11 to clamp and guide tissue paper through the roller pressing device. When the traction motor drives the rollers to rotate, the paper is clamped between the two rollers and conveyed forward. The first roller 131 and the second roller 132 are connected to the fixed base 11 through their bearings or shaft seats to ensure that they can be stably installed and rotate relative to each other. There is a drive connection between the traction motor and the first roller 131 and the second roller 132, which is usually achieved through a mechanical transmission system (such as a belt, gear, or chain) to ensure synchronous rotation of the rollers. By rotating and pressing the first roller 131 and the second roller 132, stable feeding of tissue paper can be achieved, reducing the offset or slippage of the paper during the rolling process.

[0033] In this example, the slitting mechanism 20 includes a frame 21, a slitting support 22, a slitting blade 23, and several rollers 24. Each roller is rotatably connected to the frame 21 and located at the same horizontal height. The slitting support 22 is mounted on the frame 21 and located in the middle of the frame 21. The slitting blade 23 is mounted on the slitting support 22 and is used to slit and transport the tissue paper. The winding mechanism 30 is mounted on the frame 21. Specifically, the slitting support 22 is mounted in the middle of the frame 21 to fix the slitting blade 23. The slitting blade 23 is responsible for cutting the continuously transported tissue paper to a predetermined size. Each roller is rotatably connected to the frame 21 and located at the same horizontal height, used to support and transport the tissue paper through the slitting area. The rotation of the rollers ensures that the paper passes smoothly through the slitting blade 23, achieving continuous slitting. The winding mechanism 30 is mounted on the frame 21 and is used to wind the slitted tissue paper segments into rolls. The winding mechanism 30 typically includes a roll and a drive unit for winding and securing the slit paper. The installation and adjustment of the slitting blade 23 can be easily completed on the slitting bracket 22, ensuring the accuracy and consistency of the slitting dimensions. The design of the slitting mechanism 20 allows for adjustments to the slitting dimensions according to different production needs, improving the flexibility of the production line.

[0034] In this example, the slitting blade 23 extends along the length of the slitting bracket 22 and is used to longitudinally cut tissue paper. Specifically, the slitting blade 23 extends along the length of the slitting bracket 22, and when the tissue paper passes through the slitting area, the slitting blade 23 longitudinally cuts the paper to form a paper segment of the required length. This cutting method is usually achieved through the reciprocating or rotating motion of the slitting blade 23. The cutting power can be achieved by manually operating the slitting bracket 22 or by installing a drive source. The slitting bracket 22 not only fixes the slitting blade 23 but also serves as a guide, ensuring that the slitting blade 23 accurately cuts the paper along the predetermined path, maintaining the straightness and uniformity of the cut. As the tissue paper continuously passes through the slitting area, the slitting blade 23 cuts at set intervals, thereby achieving continuous slitting operations. The slitting blade 23 extends along the length of the slitting bracket 22, making it easy to adjust the cutting length and allowing for quick adjustment of the slitting size according to production needs. Longitudinal cutting refers to cutting perpendicular to the conveying direction.

[0035] In this example, the slitting bracket 22 is provided with multiple mounting sections 221, each equipped with a slitting blade 23 for transverse cutting of tissue paper. Specifically, the slitting bracket 22 has multiple mounting sections 221, and each mounting section 221 is equipped with a slitting blade 23. Transverse cutting refers to cutting along the paper's conveying direction. When tissue paper continuously passes through the slitting bracket 22, the slitting blades 23 work together to transversely cut the paper, thereby dividing the entire roll of paper into multiple narrower rolls. The arrangement of multiple slitting blades 23 enables rapid transverse cutting, improving the efficiency of the production line, especially when multiple rolls of paper need to be cut at once. The slitting blades 23 on the multiple mounting sections 221 can be adjusted or replaced as needed to adapt to the cutting requirements of tissue paper of different widths.

[0036] In this example, a support frame 211 is provided on the side of the frame 21; the winding mechanism 30 is mounted on the support frame 211. Specifically, the support frame 211 on the side of the frame 21 provides a stable support point for the winding mechanism 30, ensuring its stability and reliability during operation. The winding mechanism 30, mounted on the support frame 211, primarily functions to wind the slit tissue paper into a roll. The winding mechanism 30 includes a roll, a drive motor, and a control system; these components work together to achieve uniform winding of the paper. The mounting of the winding mechanism 30 on the support frame 211 facilitates its installation and maintenance, as the support frame 211 provides an easily accessible platform.
