Description

Technical Field

[0001] This utility model belongs to the field of soft facial tissue production technology, specifically relating to an auxiliary equipment for the creping and forming process of soft facial tissue. Background Technology

[0002] The production of soft facial tissues refers to the process of manufacturing soft and skin-friendly paper products using virgin wood pulp, bamboo pulp, and other raw materials through a series of processes. Its core lies in balancing the softness, wet strength, and cleaning ability of the paper. The main processes include pulp preparation and disintegration, wet forming, high-temperature pressing and dehydration, and drum drying. Afterward, the paper undergoes creping, stacking, cutting into specified sizes, and folding and packaging. The entire process is carried out in a clean environment and requires strict high-temperature or ultraviolet sterilization to ensure product safety and hygiene. The final product has excellent softness, absorbency, and lint resistance, making it suitable for facial cleansing and care. According to announcement number CN223633698U, a composite wrinkling scraper is disclosed. This technology discloses a "scraper holder, the inner top wall of which is machined with a slanted groove. A wrinkling scraper is fitted between the inner top wall of the scraper and the inner wall of the slanted groove. A housing is fixedly connected to one end of the scraper holder. A corrosion-resistant structure is provided on one side of the wrinkling scraper. The corrosion-resistant structure includes a first corrosion-resistant layer, the inner wall of which is fixedly connected to the outer wall of the wrinkling scraper, and a second corrosion-resistant layer fixedly connected to the outer wall of the first corrosion-resistant layer. Through the cooperation of the wrinkling scraper and the corrosion-resistant structure, the device, during use, can utilize the first and second corrosion-resistant layers as an inorganic zinc-rich heavy-duty anti-corrosion coating. This inorganic zinc-rich heavy-duty anti-corrosion coating has excellent solvent resistance, heat resistance, and rust prevention. It not only has good anti-corrosion performance but also excellent impact resistance and wear resistance, which facilitates the improvement of the wrinkling scraper's corrosion resistance and thus avoids affecting the service life of the wrinkling scraper." While the design offers good corrosion resistance, impact resistance, and abrasion resistance, thus improving the corrosion resistance of the creping blade and preventing its lifespan, the improvements to this device focus entirely on the material properties and durability of the blade. There is no optimization or innovation regarding the core effect of the creping process—the morphology and distribution quality of the wrinkles. The blade remains rigidly fixed and operates statically, unable to introduce any dynamic variables to improve the uniformity, fineness, or complexity of the wrinkles. Therefore, it cannot fundamentally enhance the softness and premium feel of the final facial tissue product.

[0003] To address the aforementioned issues, this application proposes an auxiliary device for the creping and forming process of soft facial tissues. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an auxiliary device for the creping and forming process of soft facial tissues. A motor drives an eccentrically positioned fan-shaped eccentric block to rotate, generating periodic centrifugal force. This forces the polarizing plate and the doctor blade body to oscillate and vibrate at high frequency around the support fulcrum. Simultaneously, this vibration is guided by a buffer rod and guide groove, and absorbed and stabilized by a spring. This design upgrades the static doctor blade to a dynamic vibration-scraping system. Its composite motion can apply complex and varied mechanical disturbances at the moment of paper peeling, thereby forming a finer, more uniform, and more three-dimensional complex wrinkle structure on the paper surface. This significantly improves the ultimate softness and fluffy feel of the facial tissues. Furthermore, the dynamic contact method may help reduce localized concentrated wear on the doctor blade edge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for the creping and forming process of soft facial tissue, including a base and a bracket installed on one side of the base. One end of the bracket is connected to a connecting shaft, and the other end of the connecting shaft is connected to the surface of a polarizing plate. A scraper body is provided on the surface of the polarizing plate, and a motor is provided on one side of the polarizing plate. One end of the motor is connected to a rotating shaft, and an eccentric block is installed on the surface of the rotating shaft. A buffer connecting rod is also connected to the surface of the polarizing plate.

[0006] As a preferred auxiliary device for the soft facial tissue crease forming process of this utility model, the bracket is symmetrically installed on the surface of the base, and the bracket and the connecting shaft are rotatably connected. The connecting shaft has a "Z" shaped structure. The other end of the connecting shaft is fixedly connected to the surface of the polarizing plate. The scraper body is also fixedly installed on the surface of the polarizing plate, and a connecting seat is also installed on the surface of the polarizing plate.

[0007] As a preferred auxiliary device for the soft facial tissue crease forming process of this utility model, the motor is rotatably connected to one end of the rotating shaft, the rotating shaft is rotatably connected to the connecting seat, and two eccentric blocks are fixedly installed on the surface of the rotating shaft. The eccentric blocks are fan-shaped columnar geometric bodies.

[0008] As a preferred auxiliary device for the soft facial tissue crease forming process of this utility model, the buffer connecting rods are symmetrically installed on both sides of the surface of the polarizing plate, and the buffer connecting rods pass through the bracket and connect to the kinetic energy output plate. The surface of the bracket is provided with a guide groove, and the buffer connecting rods and the guide groove are slidably connected. Springs are connected to both sides of the surface of the kinetic energy output plate.

[0009] As a preferred auxiliary device for the soft facial tissue crease forming process of this utility model, the guide groove is in the shape of an arc structure, and the center of the circle where the arc of the guide groove is located and the center of the rotation between the bracket and the connecting shaft are on the same straight line, and the upper edge of the scraper body overlaps with the straight line.

[0010] As a preferred auxiliary device for the soft facial tissue crease forming process of this utility model, the springs are symmetrically installed on both sides of the surface of the kinetic energy output plate, and a baffle is connected to the end of the spring away from the kinetic energy output plate, and the baffle is fixedly installed on the surface of the bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by driving the eccentrically set fan-shaped eccentric block to rotate by the motor, periodic centrifugal force is generated, which forces the polarizing plate and the doctor blade body to generate high-frequency micro-amplitude oscillation and vibration around the support fulcrum. At the same time, the vibration is guided by the buffer connecting rod and the guide groove, and absorbed and stabilized by the spring. This design upgrades the static doctor blade to a dynamic vibration and scraping system. Its composite motion can apply complex and varied mechanical disturbances at the moment of paper web peeling, thereby forming a more delicate, uniform and three-dimensional complex wrinkled structure on the paper surface, which significantly improves the ultimate softness and fluffy touch of the facial tissue. At the same time, the dynamic contact method may help reduce the local concentrated wear of the doctor blade edge. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0014] like Figure 1 As shown: An auxiliary device for the creping and forming process of soft facial tissue includes a base 1.

[0015] In this implementation plan: The existing announcement number CN223633698U discloses a composite wrinkling scraper. This patent discloses a wrinkling scraper. The scraper body 5 in this application adopts the same technical means as the prior art. The technical means will not be described in detail here. For details on the improvement of the prior art, please refer to the disclosed technology below. In order to solve the technical problems existing in the prior art, such as the background technology disclosed above, "the improvement of the device is completely focused on the material performance and durability of the scraper. For the core effect of the wrinkling process, namely the shape and distribution quality of the wrinkles, there is no optimization or innovation. The scraper is still rigidly fixed and works statically. It is impossible to introduce any dynamic variables in the wrinkling process to improve the uniformity, fineness or complexity of the wrinkles. Therefore, it is impossible to fundamentally improve the soft texture and high-end touch of the final facial tissue product." In combination, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, an eccentric block 9 and a guide groove 12 are added on the basis.

[0016] Furthermore: like Figure 1 - Figure 4 As shown: In conjunction with the above, it also includes a bracket 2 installed on one side of the base 1, one end of the bracket 2 is connected to the connecting shaft 3, the other end of the connecting shaft 3 is connected to the surface of the polarizing plate 4, a scraper body 5 is provided on the surface of the polarizing plate 4, a motor 6 is provided on one side of the polarizing plate 4, the motor 6 is connected to one end of the rotating shaft 7, an eccentric block 9 is installed on the surface of the rotating shaft 7, and a buffer connecting rod 10 is also connected to the surface of the polarizing plate 4.

[0017] In this implementation plan: the device constructs a complete dynamic system of excitation, transmission, guidance, and buffering. The motor 6 drives the eccentric block 9 to generate excitation force, which is transmitted to the polarization plate 4 through the rotating shaft 7. The polarization plate 4 is supported by the connecting shaft 3 and drives the scraper body 5 to move. The buffer connecting rod 10 and the guide groove 12 precisely guide the movement into oscillation around a fixed axis, while the spring 13 ensures smooth movement. The entire mechanism works in concert to transform simple rotational input into complex and controllable micro-movements at the end of the scraper, thereby achieving a revolutionary optimization of the traditional wrinkling process.

[0018] Furthermore: In an optional embodiment, the bracket 2 is symmetrically mounted on the surface of the base 1, and the bracket 2 and the connecting shaft 3 are rotatably connected. The connecting shaft 3 has a "Z" shaped structure. The other end of the connecting shaft 3 is fixedly connected to the surface of the polarizing plate 4. The surface of the polarizing plate 4 is also fixedly mounted with a scraper body 5, and the surface of the polarizing plate 4 is also mounted with a connecting seat 8.

[0019] In this embodiment, the connecting shaft 3 with a "Z"-shaped structure is rotatably connected to the bracket 2, and the polarization plate 4 is fixed at the other end, forming a stable cantilever support structure. This structure can effectively transmit the vibration of the polarization plate 4 to the scraper body 5 and withstand the working load, ensuring the rigidity of the system.

[0020] Furthermore: In an optional embodiment, the motor 6 and one end of the shaft 7 are rotatably connected, the shaft 7 and the connecting seat 8 are rotatably connected, and two eccentric blocks 9 are fixedly installed on the surface of the shaft 7. The eccentric blocks 9 are fan-shaped columnar geometries.

[0021] In this embodiment, the rotating shaft 7 is connected to the drive source and the mounting plate through two rotating pairs, the motor 6 and the connecting seat 8, forming a stable motion linkage. The eccentric block 9 fixed on it can generate centrifugal force with periodic changes in magnitude and direction when rotating, which is a key design for efficiently and controllably generating complex excitation forces.

[0022] Furthermore: In an optional embodiment, the buffer rod 10 is symmetrically installed on both sides of the surface of the polarizing plate 4, and the buffer rod 10 passes through the bracket 2 and connects to the kinetic energy output plate 11. The surface of the bracket 2 is provided with a guide groove 12, and the buffer rod 10 and the guide groove 12 are slidably connected. Springs 13 are connected to both sides of the surface of the kinetic energy output plate 11.

[0023] In this embodiment, the buffer link 10 transmits the motion of the polarizing plate 4 to the kinetic energy output plate 11, and through cooperation with the guide groove 12, precisely constrains the complex vibration of the polarizing plate 4 into an arc swing around the bracket 2, preventing motion instability and ensuring the predictability and consistency of the working trajectory of the scraper body 5.

[0024] Furthermore: In an optional embodiment, the guide groove 12 is an arc-shaped structure, and the center of the arc of the guide groove 12 and the center of rotation between the support 2 and the connecting shaft 3 are on the same straight line, and the upper edge of the scraper body 5 overlaps with the straight line.

[0025] In this embodiment, the center of the guide groove 12 is collinear with the rotation center of the bracket 2, the connecting shaft 3 and the working point of the upper edge of the scraper body 5. This geometric relationship ensures that the swing axis of the scraper body 5 coincides with the working line of its blade when it is working, so that the swing vibration energy is most effectively converted into the lateral rubbing effect on the paper web, rather than the useless up and down jumping, thus optimizing the wrinkling dynamics.

[0026] Furthermore: In an optional embodiment, springs 13 are symmetrically mounted on both sides of the surface of the kinetic energy output plate 11, and a baffle 14 is connected to the end of spring 13 away from the kinetic energy output plate 11. The baffle 14 is fixedly mounted on the surface of the bracket 2.

[0027] In this embodiment, the spring 13 is connected between the kinetic energy output plate 11 and the baffle 14, which can effectively absorb and dissipate the excess vibration energy generated during system operation, suppress resonance, improve operational stability, and protect the drive mechanism from impact.

[0028] The working principle and usage process of this utility model are as follows: When the device wrinkles soft facial tissue, the surface of the tissue slides along the edge of the scraper body 5. At this time, the scraper body 5 can wrinkle the surface of the tissue. The motor 6, located on the surface of the polarizing plate 4, can then be activated. The motor 6 will drive the rotating shaft 7 to rotate along the connecting seat 8 to maintain the stability of the rotating shaft 7. Simultaneously, the eccentric block 9 will also rotate under the drive of the rotating shaft 7. The eccentric block 9 has an eccentric structure. When the eccentric block 9 rotates, it will cause the polarizing plate 4 and the scraper body 5 to vibrate. The kinetic energy generated by the vibration will be transmitted to the connecting shaft 3 through the polarizing plate 4. Simultaneously, the connecting shaft 3 and the bracket 2 will... The rotating process generates a rotation, and under the action of the polarizing plate 4, the doctor blade body 5 will also repeatedly swing under the drive of the connecting shaft 3. Since the edge line of the doctor blade body 5 and the midpoint of rotation between the support 2 and the connecting shaft 3 are on the same straight line, the doctor blade body 5 can make the surface texture of the paper form a higher roughness when swinging, making its texture softer. While the polarizing plate 4 swings, the polarizing plate 4 drives the buffer connecting rod 10 to slide along the guide groove 12, and the kinetic energy output plate 11 connected to the end of the buffer connecting rod 10 will work with the baffle 14 to repeatedly compress and stretch the springs 13 connected on both sides while swinging, and the springs 13 will buffer the vibration generated by the swing of the connecting shaft 3, the polarizing plate 4 and the doctor blade body 5.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
