Description

Technical Field

[0001] This invention relates to the field of toilet paper processing technology, specifically to a double-sided embossing sterile toilet paper embossing equipment. Background Technology

[0002] In the toilet paper processing and production process, the toilet paper rewinding machine is a key piece of equipment used for processing and packaging toilet paper. Its main function is to process large rolls or sheets of paper into smaller rolls or sheets of toilet paper. The functions of the toilet paper rewinding machine include rewinding, cutting, embossing, folding and stacking, and packaging. The toilet paper rewinding machine rewinds large rolls or sheets of paper, that is, transforms the paper from a wide roll or sheet form into a narrow roll or sheet form. The rewinding process requires careful control of the paper tension and speed to ensure the consistent quality of the rewound toilet paper product. The rewinding machine can also cut the rewound toilet paper rolls or sheets to obtain... The rewinding machine can produce the required specifications and dimensions; different cutting methods are available, such as straight cuts or irregular cuts, depending on the product design and market demand; the toilet paper rewinding machine also has an embossing function, which can process various patterns or designs on the toilet paper to increase the product's aesthetics and added value; for flat toilet paper, the rewinding machine can also perform folding and stacking functions, stacking the papers together to form finished packaging; the toilet paper rewinding machine will package the rewound toilet paper products, including automatic packaging of roll paper and packaging of flat paper, and different packaging methods are available, such as packaging into roll paper or packaging into flat packaging.

[0003] The embossing process of rewinding machines typically includes single-sided and double-sided embossing. Embossed tissues are less likely to unravel, and their flexibility and absorbency are enhanced. Therefore, existing toilet paper rewinding machines are usually equipped with embossing devices. However, in actual production, different batches of tissue manufacturers have different embossing requirements. When changing the embossing pattern, the embossing rollers need to be disassembled and reassembled. It is important to note that after replacing the embossing rollers, their parallelism must be readjusted to prevent the tissues from shifting. Moreover, since the embossing molds on the embossing device need to roll the tissues, especially the double-sided embossing rollers, both rollers roll the tissues. Because the raw paper rolls are dried at the factory and have undergone long-term production, the embossing rollers rub against the tissues for a long time, causing static electricity to accumulate on the rollers. At this point, the tissues will firmly adhere to the rollers, causing them to stick together, which can lead to misalignment or even breakage of the tissues.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a double-sided embossing sterile toilet paper embossing device, which solves the above technical problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is that during the embossing operation of a toilet paper rewinding machine, the embossing rollers may wear out or the embossing pattern may need to be changed, requiring workers to replace the embossing rollers. Existing embossing rollers usually require complete disassembly, which results in loss of positioning and takes a lot of time. Often, an entire embossing roller needs to be disassembled and reassembled. Furthermore, during the embossing operation, because the toilet paper is dried during production, static electricity is generated between the toilet paper and the embossing roller, causing the embossing roller to stick to the toilet paper. As the machine runs, the toilet paper may be pulled, displaced, or break.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a double-sided embossing sterile toilet paper embossing device, comprising a frame, a mounting shell, a drive mechanism, embossing rollers, a humidifying mechanism, and an auxiliary mechanism. Two embossing rollers are rotatably mounted on the inner side of the frame at both ends. The drive mechanism is fixedly mounted on the side of the embossing rollers and provides and transmits power. The humidifying mechanism is entirely mounted inside the mounting shell, with its side mounted above the embossing rollers. The auxiliary mechanism's side is mounted below the embossing rollers. The embossing rollers are positioned by dividing the embossing surface into equal sections according to the paper's embossing dimensions. A guide rail is provided inside the embossing rollers. The humidifying mechanism, through the rotation of the embossing rollers, applies a reciprocating linear pumping motion to the internal liquid of the humidifying mechanism, thereby delivering the humidifying liquid to the toilet paper surface. The cam structure inside the auxiliary mechanism performs a linear reciprocating motion perpendicular to the toilet paper processing surface under the rotation of the embossing rollers.

[0008] Based on the above, the frame supports and connects the embossing device, the mounting shell is used to fix and install the internal mechanisms of the embossing device, the drive mechanism transmits power to the drive motor, and the embossing roller is used to emboss the tissue paper. By dividing and reassembling its embossing shell, the embossing roller can be changed without disassembling the entire roller; only the shell needs to be replaced. The drive gear drives the embossing roller to rotate, and the humidification mechanism pumps humidifying liquid to the tissue paper on the embossing roller through the movement of its crank-rocker mechanism, thereby increasing the humidity on the tissue paper. This reduces the static electricity generated by friction between the embossing roller and the tissue paper, thus reducing the adhesion of the embossing roller to the tissue paper and solving the problem of tissue paper shifting or breaking due to adhesion. The auxiliary mechanism sweeps the lower surface of the tissue paper, causing it to move upward a short distance, thereby preventing the tissue paper from sticking together due to over-humidification or residual static electricity.

[0009] It is worth noting that the embossing rollers are installed in pairs, vertically, to ensure uniform embossing of the tissue paper. The embossing rollers are powered by a drive motor, which in turn drives a drive mechanism, rotating one roller. Considering the humidification mechanism requires pumping, which necessitates more power, the drive motor is connected to the transmission gear corresponding to the upper embossing roller to provide more stable power. The lower embossing roller only needs to move the tissue paper up and down, so its transmission gear drives it. Through the transmission of these two gears, the power from the drive motor is transmitted to both rollers, causing them to rotate. This, in turn, drives the humidification mechanism to humidify the tissue paper in front of the rollers, while simultaneously assisting the mechanism in moving the embossed tissue paper upwards.

[0010] The embossing roller includes a support frame, a central fixing rod, a sliding partition, an embossing shell, a locking cover plate, a positioning cover plate, an adjusting block, and a sealing end cap. The support frame supports the embossing roller. The height of the upper end face of the support frame is 3-5mm lower than the height of the lower end face of the adjusting block, and the two sides of the support frame have S-shaped slots. The two ends of the central fixing rod are rotatably connected to the inner side of the support frame. The lower end of the sliding partition is fixedly installed on the outer end face of the central fixing rod. The circumferential array of the sliding partitions forms the mounting surface of the embossing shell. The lower end height of the sliding partition is... The bottom end of the embossed outer shell is slidably mounted on the top end of the sliding partition to accommodate the difference in side length between the sliding partition and the central fixing rod. A sliding groove for sliding is provided on the lower end face of the embossed outer shell. The inner side of the locking cover plate is fixedly mounted on one side of the central fixing rod, and the locking cover plate is disc-shaped. The inner side of the positioning cover plate is fixedly mounted on the other side of the central fixing plate, and the positioning cover plate is square-shaped. The inner circumferential array of the adjusting block is fixedly mounted on the outer side of the positioning cover plate, and the inner ends of the sealing end caps are respectively fixedly mounted on the outer ends of both sides of the support frame.

[0011] Based on the above, the embossing roller is the key component for embossing operations. Through the rolling motion of the embossing roller, surface patterns are printed onto the tissue paper. Traditional one-piece embossing rollers typically have one roller corresponding to one embossing pattern. Therefore, if the embossing pattern needs to be changed, the entire roller must be replaced. However, the embossing roller, by dividing and reassembling the roller, allows the embossing pattern to be set on the outer shell of the embossing roller. That is, the outer shell has raised printing for embossing. When the embossing pattern needs to be changed, only the outer shell needs to be quickly replaced.

[0012] Further analysis reveals that the support frame supports the embossing roller, while the central fixing rod is the main body of the embossing roller. After the central fixing rod is installed on the support frame, it is adjusted and aligned; only initial adjustment and positioning are required, eliminating the need for disassembly. The sliding partition is a mounting plate for installing the embossing shell, equipped with guide rails for sliding the shell, allowing for quick disassembly, installation, and positioning. The embossing shell is the component used to achieve the embossing process. A circumferential array of embossing shells is mounted on the central fixing rod, forming a relatively closed circular embossing roller. Since the embossing roller is composed of multiple embossing shells, gaps exist at the joints. Errors during installation and issues with component machining precision can cause these gaps to protrude, squeezing the tissue paper and resulting in vertical gap marks. Therefore, rounded corners are provided at the edges of the embossing shells to ensure complete and accurate printing on the tissue paper.

[0013] Furthermore, the locking cover plate is used to limit and fix one end of the embossing shell, while the positioning cover plate is used to adjust and position the other end, thereby positioning and adjusting the entire embossing shell to achieve stable embossing of the tissue paper and reduce tissue paper displacement caused by the offset of the embossing shell; the adjusting block is used to fine-tune and fix the embossing shell, and the sealing end cap is used to fix the axial direction of the embossing roller.

[0014] The central fixing rod includes a rotating connecting shaft, a mounting base, a mounting surface, and threaded holes. The rotating connecting shaft is rotatably mounted on the inner side of the support frame. Both ends of the mounting base are fixedly connected to one end of the rotating connecting shaft. The mounting base is square in shape, and the outer plane of the mounting base is the mounting surface. Each mounting surface has a threaded hole at its upper end, and the end faces of the two sides of the mounting base have a number of threaded holes corresponding to the number of sides.

[0015] Analysis reveals that the central fixing rod is the main body of the embossing roller, and the mounting base is used to install the sliding partition. The mounting base is a regular polygon with 3-6 sides. This ensures strong support while maintaining the integrity and accuracy of the embossing pattern. The number and installation position of the embossing shells are determined by the segmentation shape of the mounting base. If the mounting base has fewer than 3 sides (two or one), it's clearly unreasonable, as the top polygon is a triangle, meaning at least 3 sides are required. Conversely, if the mounting base has more than 6 sides, the increased segmentation necessitates the installation of sliding partitions. The increased number of embossed outer shells not only increases the workload during installation and disassembly but also leads to increased installation errors. More complex installation relationships result in accumulated errors, ultimately causing a loss of installation precision. More importantly, the more embossed outer shells there are, the greater the installation gaps become. Although the above-mentioned measures have reduced interference from these gaps by using rounded corners on the embossed outer shells, these rounded corners are no longer sufficient to completely eliminate the interference as the gaps increase. The staggered raised edges of the embossed outer shells can cause incorrect embossing and markings on the tissue paper. Therefore, the optimal number of sides for the central base is 3-6.

[0016] The lower end of the sliding partition is the partition body, which is fixedly installed on the top of the central fixing rod. The upper end of the partition body is also provided with a sliding guide rail. Threaded holes are opened on both sides of the sliding guide rail. The partition body is divided into two regions, a and b, by the sliding guide rail. Region a is on the left side of the sliding guide rail, and region b is on the right side. Region a of the partition body is fixedly connected to the top of the central fixing rod. Region b of the partition body is fixedly connected to the top of the central fixing rod and is also spliced ​​to the side of region a of another sliding partition. The height of the sliding guide rail is 3 / 5 to 4 / 5 of the height of the partition body.

[0017] As described above, the sliding partition achieves rapid installation and disassembly of the embossed outer shell via its sliding guide rail. Generally, the key to rapid disassembly and installation is ensuring stable installation. The partition body is directly installed on the central fixing rod. If the installation is aligned precisely with the edge, the thickness of the partition body will cause the installation plane formed by the partition body to have non-overlapping positions. Since installing the sliding partition is an indirect enlargement of the central fixing rod, the partition bodies are spliced ​​end to end in sequence, forming an array of partition bodies with only one splicing position on the installation plane. Therefore, the partition body is divided into two areas, one wide and one narrow, by the sliding guide rail. The upper edges of the partition body have rounded corners, which correspond to the rounded corners on the embossed outer shell. Based on the analysis, it is easy to see that the junction of the partition body and the two embossed outer shells is where the installation gap is formed. Therefore, the rounded corners on the partition body here are also used to reduce the height of the protruding staggered height of the installation gap, thereby preventing incorrect embossing marks. The threaded holes on the sides of both ends of the sliding guide rail are used to connect with the adjusting block.

[0018] Furthermore, to ensure the strength of the sliding guide rail, its height should be sufficient to facilitate the sliding installation of the embossed shell while maintaining its installation strength. When the height of the sliding guide rail is less than 3 / 5 of the height of the partition body, the installation strength of the sliding guide rail is low, and it is prone to deformation under high load, which may cause the embossed shell to fall off. When the height of the sliding guide rail is greater than 4 / 5 of the height of the partition body, the excessive height of the sliding guide rail will increase the contact area of ​​the embossed shell during sliding, resulting in greater frictional resistance during sliding. This will require more effort and time from workers when installing or disassembling the embossed shell.

[0019] The middle part of the adjusting block is a convex circular base. The lower end face of the convex circular base is fixedly installed on the side of the positioning cover plate. The convex circular base is arc-shaped and the shape of the convex circular base is the same as that of the embossed shell. Fixing seats are fixedly installed on both sides of the convex circular base. Adjusting grooves are evenly opened in the middle of the convex circular base. There are 3 adjusting grooves. The length of the groove opening is 1.5-1.8 times the diameter of its corresponding threaded hole.

[0020] Therefore, the convex base is the main body of the adjusting block, and the mounting base is used for bolt or screw fixing. The adjusting block is fixedly installed around the positioning cover plate, and the adjusting groove is fixedly connected to the embossing shell by bolts or screws. The shape of the convex base is the same as that of the embossing shell to ensure proper fixing and positioning without interfering with the surface of the embossing shell. There are three adjusting grooves. The middle adjusting groove is used to connect with the sliding partition, and the two side adjusting grooves are used to fix the embossing shell. The groove opening length is 1.5-1.8 times the corresponding threaded hole diameter. When the groove opening length is less than 1.5 times the corresponding threaded hole diameter, the adjustable range of the adjusting groove is too small and cannot be effectively adjusted. When the groove opening length is greater than 1.8 times the corresponding threaded hole diameter, the adjustable range of the adjusting groove is too large, and the groove on the convex base is too large. This leads to a decrease in the strength of the convex base, and the convex base will deform or even be damaged when the embossing roller is running.

[0021] The humidification mechanism includes a rotating chamber, a pumping impeller, a pumping push rod, a pumping plug, a pumping tank, a suction pipe, a circulating water tank, and a supply assembly. The side end of the rotating chamber is fixedly installed inside the mounting housing. The pumping impeller is rotatably installed inside the rotating chamber, and its lower end is fixedly connected to the side end of the embossing roller. One end of the pumping push rod is rotatably connected to the upper end of the pumping impeller. The lower end of the pumping plug is ball-jointed to the other end of the pumping push rod. The lower end of the pumping tank is fixedly installed at the upper end of the rotating chamber, and the pumping plug is slidably installed coaxially inside the pumping tank. One end of the suction pipe is connected to the upper side of the pumping tank. The lower end of the circulating water tank is fixedly installed at the upper end of the mounting housing, and the other end of the suction pipe enters the circulating water tank from its upper side, extending to the bottom of the circulating water tank. The upper end of the supply assembly is connected to the upper side of the pumping tank, and the lower end of the supply assembly is fixedly connected to the outside of the frame.

[0022] Based on the above analysis, the humidification mechanism mainly uses the reciprocating motion of the pump plug to drive pressure changes within the pump tank, thereby drawing in and discharging the humidifying liquid from the circulating water tank. The rotating chamber is the carrier for the movement of internal parts. The pump wheel is used to transmit power, and the reciprocating motion of the pump plug is used to draw in the humidifying liquid. The suction pipe is the pipe connecting the circulating water tank and the pump tank. The suction pipe is a one-way pipe, meaning that the humidifying liquid can only flow from the circulating water tank into the pump tank and cannot flow back from the pump tank. The liquid supply component is used to transport and spray the humidifying liquid. The pipe connecting it to the circulating water tank is also a one-way pipe, meaning that the humidifying liquid can only flow out from the pump plug and cannot flow back from the liquid supply component to the pump tank.

[0023] The upper outer edge of the rotating chamber is provided with a raised inclined surface. The pump plug is circular in shape and has a downwardly extending closed baffle around its perimeter. The lower end of the closed baffle is shaped as an outward inclined surface. A connecting boss is provided at the lower ball joint of the pump plug.

[0024] It is worth noting that the rotating chamber is the cavity through which the pump impeller rotates. Since the humidification mechanism is a crank-rocker mechanism, the pump push rod will swing left and right. Because the rotating chamber is circular, its upper end will collide with the swing of the pump push rod. A raised inclined surface is provided at the upper outer edge of the rotating chamber to provide a larger range of motion for the pump push rod and prevent collisions and interference with the rotating chamber.

[0025] Furthermore, the pump plug has a downwardly extending closed baffle around its perimeter, and the lower end of the closed baffle is shaped as an outwardly inclined surface. A connecting boss is provided at the ball joint at the lower end of the pump plug. The closed baffle is used to increase the friction area between the pump plug and the moving chamber of the impeller, thereby improving the sealing effect of the pump tank and increasing the pumping capacity of the pump plug.

[0026] The liquid supply assembly includes an outlet pipe, a distribution pipe, a fixed housing, a storage chamber, an atomizing element, and a return pipe. One end of the outlet pipe is connected to the upper side of the pump tank, and one end of the distribution pipe is fixedly connected to the other end of the outlet pipe. Both ends of the fixed housing are fixedly connected to the upper end of the frame. The distribution pipe enters the interior of the fixed housing from the side, and the side of the storage chamber is fixedly connected to the other end of the distribution pipe. The upper end of the atomizing element is fixedly connected to the lower end of the storage chamber. One end of the return pipe is connected to the connection between the distribution pipe and the outlet pipe, and the other end of the return pipe is fixedly connected to the upper side of the circulating water tank.

[0027] Based on the above, the outlet pipe is used to connect to the pump liquid tank. The outlet pipe is a one-way pipe, meaning that the humidifying liquid can only enter the outlet pipe from the pump liquid tank, but cannot enter the pump liquid tank from the outlet pipe. The distribution pipe is used to guide the humidifying liquid from the outlet pipe into the storage chamber. An atomizing element is installed at the bottom of the storage chamber. The atomizing element atomizes the humidifying liquid in the storage chamber through ultrasonic vibration. The return pipe is also a one-way pipe. The humidifying liquid flows into the circulating water tank from the return pipe, but the circulating water in the circulating water tank cannot flow into the return pipe. At the same time, the return pipe and the circulating water tank are installed on the upper side of the circulating water tank.

[0028] The lower end of the fixed housing has a fan-shaped opening. The outlet pipe is installed above the return pipe. The end of the outlet pipe that connects to the pump plug and the end of the return pipe that connects to the circulating water tank are both made of detachable hose material.

[0029] The fan-shaped opening at the lower end of the fixed housing corresponds to the atomization spray range of the atomizing element. The opening angle of this fan-shaped opening affects the atomization spray angle of the atomizing element. If the opening angle is too large, the atomized spray liquid of the atomizing element will scatter everywhere. After long-term operation, the atomized liquid will drift into the machine and cause corrosion. If the opening angle is too small, the atomization spray range of the atomizing element will be reduced, and it will not be able to effectively humidify the surface of the paper towel.

[0030] The auxiliary mechanism includes a driven gear, a sliding cam, an adjusting component, a toggle plate, and a rotating ring. The driven gear is rotatably mounted inside the mounting housing and meshes with the drive gear. The sliding cam is rotatably mounted outside the driven gear. The sliding cam consists of an outer ring housing and an inner disk. The outer ring housing and the inner disk are fixedly connected by four rectangular connecting blocks arranged in a circular array. The inner side of the outer ring housing has a groove along the circumference, and the outer side of the inner disk has a boss along the circumference. One end of the adjusting component is slidably connected to the inner groove of the sliding cam. The lower end of the toggle plate is hinged to the inner side of the frame, and the upper end of the toggle plate is hinged to the other end of the adjusting component. The rotating ring is coaxially rotatably mounted on both sides of the toggle plate. An arc-shaped through groove is provided on the bracket, and the upper end of the toggle plate is slidably connected to the arc-shaped through groove through the rotating ring.

[0031] Therefore, the auxiliary mechanism mainly drives the drive gear below to rotate by rotating the embossing roller, which in turn causes the auxiliary mechanism to move with the embossing roller. The sliding cam causes the adjustment component to move, which in turn causes the actuating plate to perform up and down sweeping motion. The rotating ring is installed at the connection points of both ends of the actuating plate to reduce the friction between the actuating plate and the frame, making the movement of the actuating plate smoother.

[0032] Furthermore, the sliding cam is a key component for realizing drive and power conversion, and it also causes significant wear. The cam consists of two parts: an outer ring housing and an inner disk, which are connected by a rectangular block to ensure the connection strength. Meanwhile, the inner side of the outer ring housing has a groove along the circumference, and the inner disk has a corresponding boss. The groove and the boss form a sliding groove for the sliding installation of the adjustment component. This sliding groove is a special groove to cope with friction and can be lubricated and flattened to reduce the friction between the adjustment component and the sliding cam.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. This invention features a quickly detachable embossing roller. The outer shell of the embossing roller is composed of multiple parts. While it is quickly installed via a slide rail, locking cover plates for fixing and positioning cover plates for positioning are installed at both ends of the embossing roller. The locking cover plates allow for quick fixing and disassembly of the embossing roller. The positioning cover plates allow for fine adjustment of the outer shell of the embossing roller by adjusting the installation position of the screws on them within the slide groove, thereby achieving quick positioning. The embossing roller, through its slide groove and the end caps on both sides, enables quick disassembly, installation, and positioning of molds for different embossing patterns.

[0035] 2. The present invention also provides a humidification mechanism in front of the embossing roller. The humidification mechanism draws water from the circulating water tank through the rotation of the embossing roller and then pumps it to the top of the paper towel. By providing a humidification mechanism in front of the embossing roller, the paper surface can be humidified more precisely, thereby specifically removing static electricity from the embossing mechanism and reducing the adhesion of the embossing roller to the paper towel.

[0036] 3. This invention installs an atomizing element at the spray position of the humidification mechanism, so that the water pumped by the humidification mechanism is atomized by the atomizing element, thereby making the humidified water molecules smaller, and the humidification effect on the paper towels more delicate and uniform. This helps to prevent the paper towels from breaking due to the reduced toughness of the paper towels after humidification. It can also reduce the damage of liquid to the paper towels while removing static electricity.

[0037] 4. The present invention also includes an auxiliary mechanism. The auxiliary mechanism does not require additional power. It moves together with the embossing roller through gear transmission. The cam mechanism on the auxiliary mechanism converts the rotational motion of the embossing roller into the up-and-down linear reciprocating motion of the auxiliary mechanism. The actuating plate on the auxiliary mechanism rotates up and down, sweeping the underside of the tissue paper, thereby raising the tissue paper surface and separating it from the embossing roller. This further prevents the tissue paper from sticking to the embossing roller and solves the problem of adhesion between the embossing roller and the tissue paper. Attached Figure Description

[0053] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0054] like Figure 1 and Figure 2 As shown, a double-sided embossed aseptic toilet paper embossing device includes a frame 1, a mounting housing 2, a drive mechanism 3, embossing rollers 4, a humidifying mechanism 5, and an auxiliary mechanism 6. Two embossing rollers 4 are rotatably mounted on the inner side of the frame 1 at both ends. The drive mechanism 3 is fixedly mounted on the side of the embossing rollers 4 and provides and transmits power. The humidifying mechanism 5 is entirely mounted inside the mounting housing 2, with its side mounted above the side of the embossing rollers 4. The auxiliary mechanism 6 is mounted on the side of the embossing rollers 4. Below; the embossing roller 4, according to the embossing size of the paper, divides the embossing surface into equal parts, thereby achieving rapid installation and positioning of the embossing surface of the embossing roller 4; and the embossing roller 4 is provided with a guide rail inside, and end caps for locking and unlocking are installed at both ends of the embossing roller 4. The humidification mechanism 5 applies a reciprocating linear pumping motion to the liquid inside the humidification mechanism 5 through the rotational movement of the embossing roller 4. The cam structure inside the auxiliary mechanism 6 makes a linear reciprocating motion perpendicular to the paper towel processing surface under the rotational movement of the embossing roller 4.

[0055] During operation, the drive mechanism 3 drives the embossing roller 4 to rotate. The upper embossing roller 4 drives the humidification mechanism 5 to operate, thereby humidifying the paper towel in front of the embossing roller 4. The lower embossing roller 4 drives the upper end of the auxiliary mechanism 6 to perform a reciprocating linear motion, thereby sweeping the paper towel after it has been embossed by the embossing roller 4 upwards.

[0056] The frame 1 supports and connects the embossing device, the mounting housing 2 is used to fix and install the internal mechanisms of the embossing device, the embossing roller 4 is used to emboss the tissue paper, and the embossing roller 4, through the division and reassembly of its embossing housing 44, allows the embossing roller 4 to be replaced without disassembling the entire roller, only the housing needs to be replaced, when changing the embossing pattern; the drive gear drives the embossing roller 4 to rotate, and the humidification mechanism 5, through the movement of its crank-rocker mechanism, pumps humidifying liquid to the tissue paper on the embossing roller 4. This increases the humidity on the paper towel, which reduces the static electricity generated by the friction between the embossing roller 4 and the paper towel, thereby reducing the adhesion of the embossing roller 4 to the paper towel and solving the problem of paper towel shifting or breaking due to adhesion. The auxiliary mechanism 6 is used to sweep the lower surface of the paper towel, causing the paper towel to move upward a short distance, thereby preventing the paper towel from sticking due to over-humidification or residual static electricity. The embossing roller 4 is installed in pairs, vertically, to ensure that the two embossing rollers 4 emboss the paper towel surface evenly.

[0057] like Figure 3 and Figure 4 As shown, the embossing roller 4 includes a support frame 41, a central fixing rod 42, a sliding partition 43, an embossing shell 44, a locking cover plate 44, a positioning cover plate 46, an adjusting block 47, and a sealing end cover 48. The support frame 41 supports the embossing roller 4. The height of the upper end face of the support frame 41 is 3mm lower than the height of the lower end face of the adjusting block 47, and the two sides of the support frame 41 are S-shaped slots. The two ends of the central fixing rod 42 are rotatably connected to the inner side of the support frame 41. The lower end of the sliding partition 43 is fixedly installed on the outer end face of the central fixing rod 42. The circumferential array of the sliding partitions 43 forms the mounting surface of the embossing shell 44. The lower end height value is the difference in side length between the sliding partition 43 and the central fixing rod 42. The bottom end of the embossed outer shell 44 is slidably installed on the top end of the sliding partition 43. The lower end surface of the embossed outer shell 44 is provided with a sliding groove. The inner side of the locking cover plate 44 is fixedly installed on one side of the central fixing rod 42. The locking cover plate 44 is disc-shaped. The inner side of the positioning cover plate 46 is fixedly installed on the other side of the central fixing plate. The positioning cover plate 46 is square-shaped. The inner end of the adjusting block 47 is circumferentially arrayed and fixedly installed on the outer side of the positioning cover plate 46. The inner end of the sealing end cover 48 is fixedly installed on the outer ends of both sides of the support frame 41.

[0058] During installation and disassembly of the embossing roller 4: During installation, firstly, the two ends of the central fixing rod 42 are rotatably mounted on the support frame 41 via bearings, ensuring that both ends are horizontal during installation to prevent tissue paper misalignment. Then, the sliding partition 43 is fixedly connected to the upper end of the central fixing rod 42 using bolts or screws. Next, the embossing outer shell 44 is slidably mounted on the sliding partition 43, allowing it to slide along the axial direction. Finally, the locking cover 44 is fixedly mounted on the side of one end of the central fixing rod 42 and also fixedly connected to one end of the embossing outer shell 44. The positioning cover plate 46 is fixedly connected to the side of the other end of the central fixing rod 42. At this time, one direction of the axial direction of the embossed outer shell 44 is restricted. Then, the adjusting block 47 is installed on the upper end of the positioning cover plate 46 and fixedly connected to the other end of the embossed outer shell 44, thereby fixing the movement of the embossed outer shell 44 in the other axial direction. Finally, the sealing end cover 48 is fixedly installed on the side of the support frame 41. When disassembling, first loosen the screw on the locking cover plate 44 at one end of the central fixing rod 42, then loosen the screw on the adjusting block 47, and pull out the embossed outer shell 44 along the sliding partition 43 for replacement.

[0059] The support frame 41 is used to support the embossing roller 4. The height of the upper end face of the support frame 41 is 3-5mm lower than the height of the lower end face of the adjusting block 47. The two sides of the support frame 41 have S-shaped slots. The S-shaped slots are mainly for easy disassembly and installation, and to reduce collisions and interference during installation. When the height of the upper end face of the support frame 41 is 3mm lower than the height of the lower end face of the adjusting block 47, the installation height of the support frame 41 is too low, which will expose the internal connection parts of the embossing roller 4 and make them susceptible to corrosion by external dust. When the height of the upper end face of the support frame 41 is 5mm higher than the height of the lower end face of the adjusting block 47, the height of the support frame 41 is too high, which will interfere with the installation and disassembly of the embossing roller 4 and cause collisions between the mechanisms.

[0060] The central fixing rod 42 is the main body of the embossing roller 4. After the central fixing rod 42 is installed on the support frame 41, it is adjusted and aligned. Only the initial positioning adjustment is required during the initial installation, and it does not need to be disassembled. The sliding partition 43 is a mounting plate for installing the embossing shell 44. It is provided with guide rails for the sliding of the embossing shell 44, so that the embossing shell 44 can slide out for disassembly, as well as for quick installation and positioning. The embossing shell 44 is the part used to achieve embossing. The embossing shell 44 is arranged in a circumferential array on the support frame 41. A relatively closed circular embossing roller 4 is formed on the central fixing rod 42. Since the embossing roller 4 is composed of multiple embossing shells 44, there will be gaps at the joints of the embossing shells 44. During the installation process, there will be errors and problems with the precision of parts processing. This will cause the gaps at the joints of the embossing shells 44 to have a raised height, which will squeeze the paper towel and cause vertical gap marks on the paper towel. Therefore, rounded corners are provided at the edges of the embossing shells 44 to ensure that the printing on the paper towel is complete and accurate.

[0061] The locking cover plate 44 is used to limit and fix one end of the embossing shell 44, while the positioning cover plate 46 is used to adjust and position the other end, thereby positioning and adjusting the entire embossing shell 44 to achieve stable embossing of the tissue and reduce tissue displacement caused by the offset of the embossing shell 44; the adjusting block 47 is used to fine-tune and fix the embossing shell 44, and the sealing end cap 48 is used to fix the axial direction of the embossing roller 4.

[0062] As shown in Figures 41 and 42, the central fixing rod 42 includes a rotating connecting shaft 421, a mounting base 422, and a mounting surface 423. The rotating connecting shaft 421 is rotatably mounted on the inner side of the support frame 41. The two ends of the mounting base 422 are coaxially fixedly connected to the end faces of the rotating connecting shaft 421. The mounting base 422 is square in shape, and the outer plane of the mounting base 422 is the mounting surface 423. Each mounting surface 423 has a threaded hole 424 at its upper end, and the end faces of the two sides of the mounting base 422 have a number of threaded holes 424 corresponding to the number of sides.

[0063] In actual production, considering the manufacturing process of the central fixing rod 42, a regular quadrilateral shape is chosen for the mounting bracket. This eliminates the need for complex polygonal cutting calculations when processing the embossed outer shell 44; it only requires cutting along 1 / 4 of the circumference to obtain the embossed outer shell 44. The threaded hole 424 on the end face of the mounting base 422 is used to install and fix the sliding partition 43. Since the mounting base 422 and the sliding partition 43 have different strengths, the mounting base 422, as a support and fixation element, has... The bending strength is greater than that of the sliding partition 43. The two are fixedly connected by screws and threaded holes 424. The threaded holes 424 on the sliding partition 43 will affect the strength of the sliding partition 43. Considering this issue, it is necessary to ensure that the sliding partition 43 and the mounting support have a sufficiently strong connection while also ensuring that the sliding partition 43 will not be deformed or damaged. Therefore, the threaded holes on the sliding partition 43 should be evenly distributed, and the spacing between the evenly distributed holes should be 1 / 6 of the total length of the mounting base 422. Threaded holes 424 are provided near both ends.

[0064] The central fixing rod 42 is the main body of the embossing roller 4. The mounting base 422 is used to mount the sliding partition 43. The mounting base 422 is a regular polygon with 1 / 2 sides. This ensures that the mounting base 422 has strong support capacity while also ensuring the integrity and accuracy of the embossing pattern. The number and installation position of the embossing shell 44 are determined according to the segmented shape of the mounting base 422. When the number of sides of the mounting base 422 is less than 3 (i.e., two or one), it is obviously unreasonable, as the top polygon is a triangle, which means at least 3 sides. When the number of sides of the mounting base 422 is greater than 6, more segments are formed. The number of installations increases, leading to a greater number of embossed outer shells 44 that need to be installed. This not only increases the workload during installation and disassembly but also increases the installation error of the embossed outer shells 44. More installation relationships result in the accumulation of installation errors, ultimately leading to a loss of installation accuracy. More importantly, the more embossed outer shells 44 there are, the greater the installation gaps become. Although the above-mentioned measures have reduced the interference of installation gaps on the embossing by rounding the corners on the embossed outer shells 44, as the installation gaps increase, rounding the corners can no longer completely avoid the interference of installation gaps. The staggered protruding edges of the embossed outer shells 44 will cause incorrect embossing and imprints on the tissue paper; therefore, the number of sides of the central base is preferably 4.

[0065] like Figure 6 and Figure 7As shown, the lower end of the sliding partition 43 is the partition body 431, which is fixedly installed on the top of the central fixing rod 42. The upper end of the partition body 431 is also provided with a sliding guide rail 432. Threaded holes 424 are opened on both sides of the sliding guide rail 432. The partition body 431 is divided into two regions, a and b, by the sliding guide rail 432. Region a is on the left side of the sliding guide rail 432, and region b is on the right side. Region a of the partition body 431 is fixedly connected to the top of the central fixing rod 42. Region b of the partition body 431 is fixedly connected to the top of the central fixing rod 42 and is also spliced ​​to the side of region a of the other sliding partition 43. The height of the sliding guide rail 432 is 4 / 5 of the height of the partition body 431.

[0066] During the processing of the sliding partition 43, the partition body 431, i.e., the plate material, is cut out first, and its dimensions are divided to mark the installation position of the sliding guide rail 432. The width of the partition body 431 is the width of the mounting support plus the thickness of the partition body 431. When installing the sliding guide rail 432, a direct welding connection method is adopted. The dimension reference is the width of the mounting support. First, the width value corresponding to the mounting support is marked on the partition body 431, and the sliding guide rail 432 is welded at half of this width value. The height of the sliding guide rail 432 is 4 / 5 of the height of the partition body 431, so as to ensure that the sliding guide rail 432 has the pressure to support the embossed shell 44 when it is working.

[0067] The sliding partition 43 enables quick installation and rapid removal / removal of the embossed outer shell 44 via its sliding guide rail 432. Generally, the key to quick installation and removal is ensuring stable installation. If the partition body 431 is directly installed on the central fixing rod 42, and the edges are aligned precisely, the thickness of the partition body 431 will result in non-overlapping areas on the mounting plane. Since installing the sliding partition 43 is an indirect enlargement of the central fixing rod 42, the partition bodies 431 are sequentially spliced ​​end-to-end to form a single splice on the mounting plane. The array of the partition body 431 at the connection position is such that the partition body 431 is divided into two regions, one wide and one narrow, by the sliding guide rail 432; the upper two sides of the partition body 431 have rounded corners, which correspond to the rounded corners on the embossed outer shell 44. According to the analysis, it is not difficult to see that the junction of the partition body 431 and the two embossed outer shells 44 is the position where the installation gap is formed. Therefore, the rounded corners on the partition body 431 at this point are also used to reduce the height of the protrusions of the installation gap, thereby preventing incorrect embossing marks; the threaded holes 424 opened on the two sides of the sliding guide rail 432 are used to connect with the adjusting block 47.

[0068] To ensure the strength of the sliding guide rail 432, its height should be sufficient to facilitate the sliding installation of the embossed outer shell 44 while maintaining its installation strength. When the height of the sliding guide rail 432 is less than 3 / 5 of the height of the partition body 431, its installation strength is low, and it is prone to deformation under high load, which may cause the embossed outer shell 44 to fall off. When the height of the sliding guide rail 432 is greater than 4 / 5 of the height of the partition body 431, the excessive height of the sliding guide rail 432 will increase the contact area of ​​the embossed outer shell 44 during sliding, resulting in greater frictional resistance during sliding. This will require more effort and time from workers when installing or disassembling the embossed outer shell 44.

[0069] like Figure 9 As shown, the middle part of the adjusting block 47 is a convex circular base 471. The lower end face of the convex circular base 471 is fixedly installed on the side of the positioning cover plate 46. The convex circular base 471 is arc-shaped and has the same shape as the embossed outer shell 44. Fixing seats 472 are fixedly installed on both sides of the convex circular base 471. Adjusting grooves 473 are evenly opened in the middle position of the convex circular base 471. There are 3 adjusting grooves 473. The groove opening length of the adjusting groove 473 is 1.5 times the diameter of its corresponding threaded hole.

[0070] The adjusting block 47 is processed according to the shape of the embossed outer shell 44. The main body shape of the adjusting block 47 is the same as that of the embossed outer shell 44. The adjusting block 47 has an arc edge block with a circumference of 1 / 4. The threaded hole 424 on the fixing seat 472 is fixedly connected to the upper end face of the positioning cover plate 46 by screws. The convex round base 471 in the middle has an adjusting groove 473 for connecting the sliding partition 43 and the embossed outer shell 44. The groove length of the adjusting groove 473 corresponds to the adjustable range of motion.

[0071] The convex base 471 is the main body of the adjusting block 47, and the fixing seat 472 is a base for bolt or screw fixing. The adjusting block 47 is fixedly installed around the positioning cover plate 46, and the adjusting groove 473 is fixedly connected to the embossed outer shell 44 by bolts or screws. The shape of the convex base 471 is the same as the shape of the embossed outer shell 44 to ensure proper fixing and positioning without interfering with the surface of the embossed outer shell 44. There are three adjusting grooves 473. The middle adjusting groove 473 is used to connect with the sliding partition 43, and the two adjusting grooves 473 on both sides are used to fix the embossed outer shell 44.

[0072] like Figure 10 As shown, the humidification mechanism 5 includes a rotating chamber 51, a pumping wheel 52, a pumping push rod 53, a pumping plug 54, a pumping tank 55, a suction pipe 56, a circulating water tank 57, and a liquid supply assembly 58. The side end of the rotating chamber 51 is fixedly installed inside the mounting housing 2. The pumping wheel 52 is rotatably installed at the center of the rotating chamber 51. The center of rotation of the pumping wheel 52 is coaxially connected to the side end of the embossing roller 4. One end of the pumping push rod 53 is rotatably connected to the center of rotation of the pumping wheel 52. The lower end of the pumping plug 54 is ball-jointed to the other end of the pumping push rod 53. The lower end of the pump liquid tank 55 is fixedly installed on the upper end of the rotating wheel movable cavity 51. The pump liquid plug 54 is slidably installed coaxially inside the pump liquid tank 55. One end of the suction pipe 56 is connected to the upper side of the pump liquid tank 55. The lower end of the circulating water tank 57 is fixedly installed on the upper end of the mounting shell 2. The other end of the suction pipe 56 enters the interior of the circulating water tank 57 from the upper side of the circulating water tank 57. The other end of the suction pipe 56 extends to the bottom of the circulating water tank 57. The upper end of the liquid supply assembly 58 is connected to the upper side of the pump liquid tank 55. The lower end of the liquid supply assembly 58 is fixedly connected to the outside of the frame 1.

[0073] When the humidification mechanism 5 is working, a pumping wheel 52 is installed in the rotating chamber 51. The pumping wheel 52 starts to rotate under the drive of the drive gear, which in turn drives the pumping push rod 53 to move. At the same time, the pumping plug 54 makes a reciprocating linear motion. When the pumping plug 54 moves downward, the upper part of the pumping tank 55 will use the suction pipe 56 to draw the humidification liquid in the circulating water tank 57. The humidification liquid enters the upper part of the circulating water tank 57. At this time, when the pumping plug 54 moves upward, the liquid in the pumping tank 55 is squeezed. Since the suction pipe 56 is equipped with a one-way valve, the suction pipe 56 cannot discharge the liquid at this time. Therefore, the liquid will be discharged from the liquid supply assembly 58, thereby spraying the humidification liquid onto the paper towel for humidification.

[0074] The humidification mechanism 5 mainly uses the reciprocating motion of the pump plug 54 to drive pressure changes in the pump tank 55, thereby drawing in and discharging the humidifying liquid from the circulating water tank 57. The rotating chamber 51 is the carrier for the movement of internal parts, the pump wheel 52 is used to transmit power, the reciprocating motion of the pump plug 54 is used to draw in the humidifying liquid, and the suction pipe 56 is a pipe connecting the circulating water tank 57 and the pump tank 55. The suction pipe 56 is a one-way pipe, meaning that the humidifying liquid can only flow from the circulating water tank 57 into the pump tank 55 and cannot flow back from the pump tank 55 to the circulating water tank 57. The liquid supply assembly 58 is used to transport and spray the humidifying liquid. The pipe at its connection with the circulating water tank 57 is also a one-way pipe, meaning that the humidifying liquid can only flow out from the pump plug 54 and cannot flow back from the liquid supply assembly 58 to the pump tank 55.

[0075] like Figure 10 As shown, a raised inclined surface 511 is provided at the upper outer edge of the rotating wheel movable cavity 51, the pump plug 54 is circular in shape, and the pump plug 54 has a downwardly extending closed baffle 541 around its perimeter, and the lower end of the closed baffle 541 is shaped as an outward inclined surface, and a connecting boss 542 is provided at the lower end of the pump plug 54 at the ball joint.

[0076] The rotating chamber 51 is the cavity through which the pumping impeller 52 rotates. Since the humidification mechanism 5 is a crank-rocker mechanism, the pumping push rod 53 will swing left and right. Because the rotating chamber 51 is circular, its upper end will collide with the swinging of the pumping push rod 53. A raised inclined surface 511 is provided at the upper outer edge of the rotating chamber 51 to provide a larger range of motion for the pumping push rod 53 and prevent collisions and interference with the rotating chamber 51. The pumping plug 54 has a downwardly extending closed baffle 541 around its perimeter, and the lower end of the closed baffle 541 is shaped as an outward inclined surface. A boss is provided at the ball joint of the lower end of the pumping plug 54. The closed baffle 541 is used to increase the friction area between the pumping plug 54 and the rotating chamber 51, thereby improving the sealing effect of the pumping tank 55 and increasing the pumping capacity of the pumping plug 54.

[0077] like Figure 11 and Figure 12 As shown, the liquid supply assembly 58 includes an outlet pipe 581, a distributing pipe 582, a fixed housing 583, a storage chamber 584, an atomizing element 585, and a return pipe 586. One end of the outlet pipe 581 is connected to the upper side of the pump tank 55. One end of the distributing pipe 582 is fixedly connected to the other end of the outlet pipe 581. Both ends of the fixed housing 583 are fixedly connected to the upper end of the frame 1. The distributing pipe 582 enters the interior of the fixed housing 583 from the side, and the side of the storage chamber 584... The upper end of the atomizing element 585 is fixedly connected to the lower end of the liquid storage chamber 584, and one end of the return pipe 586 is connected to the connection between the distribution pipe and the outlet pipe 581. The other end of the return pipe 586 is fixedly connected to the upper side of the circulating water tank 57. The installation position of the outlet pipe 581 is located above the installation position of the return pipe 586. The end of the outlet pipe 581 connected to the pump plug 54 and the end of the return pipe 586 connected to the circulating water tank 57 are both made of detachable hose material.

[0078] When the liquid supply assembly 58 is in operation, when the pump plug 54 in the pump liquid tank 55 moves downward, the one-way valve in the outlet pipe 581 will be closed to ensure that the pump plug 54 can smoothly draw humidifying liquid. When the pump plug 54 moves upward, the liquid in the pump liquid tank 55 flows out from the outlet pipe 581 and then enters the storage chamber 584 in the fixed housing 583 from the distribution pipe 582. At this time, the atomizing element 585 is energized to perform ultrasonic atomization treatment on the humidifying liquid in the storage chamber 584. When the storage chamber 584 is full of humidifying liquid, the humidifying liquid will flow from the return pipe 586 into the circulating water tank 57 under the reciprocating motion of the pump plug 54.

[0079] The outlet pipe 581 is used to connect to the pump liquid tank 55. The outlet pipe 581 is a one-way pipe, meaning that the humidifying liquid can only enter the outlet pipe 581 from the pump liquid tank 55, but cannot enter the pump liquid tank 55 from the outlet pipe 581. The distribution pipe 582 is used to guide the humidifying liquid from the outlet pipe 581 into the storage chamber 584. An atomizing element 585 is installed at the bottom of the storage chamber 584. The atomizing element 585 atomizes the humidifying liquid in the storage chamber 584 through ultrasonic vibration. The return pipe 586 is also a one-way pipe. The humidifying liquid flows into the circulating water tank 57 from the return pipe 586, while the circulating water in the circulating water tank 57 cannot flow into the return pipe 586. At the same time, the installation position of the return pipe 586 and the circulating water tank 57 is located on the upper side of the circulating water tank 57.

[0080] The fan-shaped opening at the lower end of the fixed housing 583 corresponds to the atomization spray range of the atomizing element 585. The opening angle of the fan-shaped opening affects the atomization spray angle of the atomizing element 585. If the opening angle is too large, the atomized spray liquid of the atomizing element 585 will scatter everywhere. Under long-term operation, the atomized liquid will drift into the machine and cause corrosion. If the opening angle is too small, the atomization spray range of the atomizing element 585 will be reduced, and it will not be able to effectively humidify the surface of the paper towel.

[0081] The fan-shaped opening at the lower end of the fixed housing 583 can be determined according to the atomization spray range of the atomizing element 585. The installation position of the liquid outlet pipe 581 should be higher than the position of the return pipe 586. The liquid outlet pipe 581 is fixedly installed on the side of the fixed housing 583, and the return pipe 586 is also fixedly installed on the side of the fixed housing 583. Both of them surround the side of the fixed housing 583 vertically. The connection between the liquid outlet pipe 581 and the return pipe 586 is a T-junction double elbow connecting pipe. The diverter pipe is connected to the liquid outlet pipe 581 and the return pipe 586 through this connecting pipe. The end of the liquid outlet pipe 581 connected to the pump plug 54 and the end of the return pipe 586 connected to the circulating water tank 57 are both made of detachable hose material to ensure that the connecting pipes can be quickly replaced and disassembled.

[0082] like Figure 12As shown, the auxiliary mechanism 6 includes a driven gear 61, a sliding cam 62, an adjusting assembly 63, a toggle plate 64, and a rotating ring 65. The driven gear 61 is rotatably mounted inside the mounting housing 2 and meshes with the drive gear. The sliding cam 62 is rotatably mounted outside the driven gear 61. The sliding cam 62 is composed of an outer ring housing 611 and an inner disk 612. The outer ring housing 611 and the inner disk 612 are fixedly connected by four rectangular connecting blocks arranged in a circular array. The inner side of the 611 has a groove along the circumference, and the outer side of the inner disc 612 has a boss along the circumference. One end of the adjusting component 63 is slidably connected to the inner groove of the sliding cam 62. The lower end of the actuating plate 64 is hinged to the inner side of the frame 1, and the upper end of the actuating plate 64 is hinged to the other end of the adjusting component 63. The rotating ring 65 is coaxially rotatably mounted on both sides of the actuating plate 64. An arc-shaped through groove is provided on the bracket, and the upper end of the actuating plate 64 is slidably connected to the arc-shaped through groove through the rotating ring 65.

[0083] When the auxiliary mechanism 6 is working, the driven gear 61, driven by the drive gear, drives the sliding cam 62 to rotate. At this time, the adjustment component 63 uses the movement of the sliding cam 62 to make a reciprocating linear motion. The rotating ring 65 is slidably installed with the frame 1. The front end of the adjustment component 63 will drive the actuating plate 64 to move. At this time, the two ends of the actuating plate 64 will drive the rotating ring 65 to slide in the slide groove of the frame 1, thereby driving the actuating plate 64 to sweep upwards, thereby lifting and sweeping the lower surface of the paper towel.

[0084] The auxiliary mechanism 6 mainly rotates by rotating the embossing roller 4, which in turn drives the drive gear below to rotate, causing the auxiliary mechanism 6 to move along with the embossing roller 4. The sliding cam 62 causes the adjusting component 63 to move, thereby causing the actuating plate 64 to perform up-and-down sweeping motion. The rotating ring 65 is installed at both ends of the actuating plate 64 to reduce friction between the actuating plate 64 and the frame 1, making the movement of the actuating plate 64 smoother. The sliding cam 62 is a key component for realizing drive and power conversion, and the wear it causes... The wear and tear will also be relatively large. The cam is composed of two parts, an outer ring shell 611 and an inner disc 612. The two are connected by a rectangular block to ensure the connection strength. At the same time, the inner side of the outer ring shell 611 is provided with a groove along the circumference. Correspondingly, the inner disc 612 is also provided with a boss. The groove and the boss form a sliding groove for the sliding installation of the adjustment component 63. This sliding groove is a special groove to deal with friction. It can be oiled and flattened to reduce the friction between the adjustment component 63 and the sliding cam 62.

[0085] It is worth noting that the adjustment component 63 uses any mechanism that can cooperate with the movement of the sliding cam 62. The mechanism used here is simply a rocker mechanism that can be easily adjusted. By adjusting the fulcrum of the rocker by the lead screw, the adjustment component 63 can adjust the amplitude of its up-and-down reciprocating movement.

[0086] In the operation of this invention, the embossing roller 4 is first installed onto the support frame 41. Specifically, the two ends of the central fixing rod 42 are rotatably installed onto the support frame 41 via bearings, ensuring that the two ends are horizontal during installation. Then, the sliding partition 43 is fixedly connected to the upper end of the central fixing rod 42 by bolts or screws. Next, the embossing shell 44 is slidably installed onto the sliding partition 43. At this time, the embossing shell 44 is in a movable state that can slide along the axial direction. Then, the locking cover 44 is fixedly installed on the side of one end of the central fixing rod 42 and is also fixedly connected to one end of the embossing shell 44. The positioning cover 46 is fixedly connected to the side of the other end of the central fixing rod 42. Then, the adjusting block 47 is installed on the upper end of the positioning cover 46 and fixedly connected to the other end of the embossing shell 44. Finally, the sealing end cap 48 is fixedly installed on the side of the support frame 41.

[0087] After installation, the drive mechanism 3 starts and drives the embossing roller 4 to rotate. The embossing roller 4 drives the humidification mechanism 5 to move, that is, the pumping wheel 52 starts to rotate under the drive gear, which in turn drives the pumping push rod 53 to move. At the same time, the pumping plug 54 makes a reciprocating linear motion up and down. When the pumping plug 54 moves downward, the upper part of the pumping tank 55 will use the suction pipe 56 to draw the humidification liquid in the circulating water tank 57. The humidification liquid enters the upper part of the circulating water tank 57. At this time, when the pumping plug 54 moves upward, the liquid in the pumping tank 55 is squeezed. Due to the suction... A one-way valve is installed inside the liquid pipe 56. At this time, the liquid pipe 56 cannot discharge liquid, and the liquid will be discharged from the liquid supply component 58, thereby spraying the humidifying liquid onto the paper towel to humidify it, thus humidifying the paper towel in front of the embossing roller 4. The lower embossing roller 4 drives the upper end of the auxiliary mechanism 6 to make up-down reciprocating linear motion. The driven gear 61 inside it drives the sliding cam 62 to rotate under the drive gear. At this time, the adjustment component 63 uses the motion of the sliding cam 62 to make up-down reciprocating linear motion, thereby driving the actuating plate 64 to sweep upwards, thereby lifting and sweeping the lower surface of the paper towel.
