Description

Technical Field

[0001] The invention relates to the technical field of fixed-scent paper towels, in particular to a fixed-scent paper towel and a production process thereof. Background Art

[0002] Fixed-scented tissue paper is a specific tissue paper with added fragrances. The pleasant aroma emitted by fixed-scented tissue paper when used can give people a fresh and pleasant feeling. Some tissue paper scents have the effect of soothing nerves and relieving stress.

[0003] However, when fixed-scented tissue paper is used, as the adhesion of the fragrance molecules on the surface of the tissue paper weakens, the fragrance of the tissue paper dissipates faster and the fragrance cannot be retained for a long time.

[0004] For example, a Chinese patent with application number 2018112496345 discloses a method for producing antibacterial colored scented tissue paper, which includes the following steps: S1, preparing natural antibacterial scented liquid; S2, pulping color paste; S3, papermaking; S4, scented liquid attachment; S5, finished product. The invention, through the combination of raw materials and processes, configures a natural antibacterial fragrance liquid with stable performance and no need for refrigeration, avoiding the problem that the use of traditional chemical materials makes the antibacterial fragrance not natural and healthy enough, while retaining the original ingredients, fragrance, antibacterial, antiviral and antioxidant functions of the natural antibacterial fragrance liquid, and attaches the natural antibacterial fragrance liquid to the paper towel by spraying and roller adhesion, solving the shortcomings of traditional paper towels that cannot have natural fragrance, natural antibacterial function and gorgeous colors at the same time. At the same time, the attachment amount can be controlled by spraying and roller adhesion to adjust the fragrance intensity, antibacterial effect and production cost of the paper product. Although the invention, through the combination of raw materials and processes and the control of the attachment amount by spraying and roller adhesion to adjust the fragrance intensity, antibacterial effect and production cost of the paper product, there is a problem that when the paper product is sprayed, the diffusion of perfume molecules will cause the amount of perfume attached to the paper product to decrease, and quantitative spraying cannot be performed, and the durability of the fragrance of the paper towel cannot be maintained. In addition, the paper product is scented by spraying, which easily causes the problem of cross-flavor with the fragrance of other paper products.

[0005] Therefore, the present invention proposes a scent-fixing paper towel and a production process thereof to solve the above problems. Summary of the invention

A plurality of first protrusions 411 are uniformly arranged on the outer wall of the first composite member 41 in the circumferential and axial directions. A plurality of second protrusions 421 are uniformly arranged on the outer wall of the second composite member 42 in the circumferential and axial directions. The first composite member 41 and the second composite member 42 are arranged in parallel. At one end of the frame 1 away from the perfume storage tank 101, a third motor for driving the first composite member 41 to rotate and a fourth motor for driving the second composite member 42 to rotate are provided. The central axes of the first pressing member 22, the second pressing member 32, the first rotating member 29 and the second rotating member 39 are coplanar and parallel. The plane formed by the central axes of the first pressing member 22 and the second pressing member 32 is parallel to the plane formed by the central axes of the first composite member 41 and the second composite member 42. The first liquid inlet chamber 211 and the second liquid inlet chamber 311 are both connected to the output end of the perfume storage tank 101 through pipelines.

[0064] In use, the perfume solution is respectively conveyed into the first liquid inlet cavity 211 and the second liquid inlet cavity 311 through a pipeline by the perfume storage tank 101. At the same time, the first motor and the second motor are started. The rotation of the first motor drives the first pressing member 22 to rotate counterclockwise. Similarly, the second motor drives the second pressing member 32 to rotate clockwise. While the first pressing member 22 rotates counterclockwise, it drives the first rotating member 29 to rotate clockwise. Similarly, while the second pressing member 32 rotates clockwise, it drives the second rotating member 39 to rotate counterclockwise. The third motor and the fourth motor are started. The third motor drives the first composite member 41 to rotate counterclockwise, and the fourth motor drives the second composite member 42 to rotate clockwise.

[0065] First, adjust the machine. One end of the core layer part 200 is placed between the first pressing member 22 and the second pressing member 32. The first pressing member 22 rotates counterclockwise on the first fragrance-fixing member 21, and the second pressing member 32 rotates clockwise on the second fragrance-fixing member 31. While the first pressing member 22 and the second pressing member 32 rotate, the first piston 231 slides in the first chute 23. At the same time, one end of the first piston 231 slides in the third annular groove 224. While the first piston 231 slides in the third annular groove 224, the high-pressure perfume in the first liquid inlet cavity 211 enters the inner cavity of the first chute 23 through the first communication hole 25 and the one-way valve. Similarly, the third piston 331 slides in the fourth chute 33. At the same time, one end of the third piston 331 slides in the fourth annular groove 324. While the third piston 331 slides in the fourth annular groove 324, the high-pressure perfume in the second liquid inlet cavity 311 enters the inner cavity of the fourth chute 33 through the fourth communication hole 35 and the one-way valve. The high-pressure perfume in the inner cavity of the first chute 23 enters the inner cavity of the second chute 24 through the second communication hole 26. The high-pressure perfume in the inner cavity of the second chute 24 contacts the second piston 241 through the third communication hole 27. Since one end of the second piston 241 contacts the inner wall of the first pressing member 22, the first annular groove 243 is misaligned with the third communication hole 27 and not conducting. Similarly, the high-pressure perfume in the inner cavity of the fourth chute 33 enters the inner cavity of the fifth chute 34 through the fifth communication hole 36. The high-pressure perfume in the inner cavity of the fifth chute 34 contacts the fourth piston 341 through the sixth communication hole 37. Since one end of the fourth piston 341 contacts the inner wall of the second pressing member 32, the second annular groove 343 is misaligned with the sixth communication hole 37 and not conducting.

[0066] As the first pressing member 22 and the second pressing member 32 rotate, when the first pressing head 221 and the multiple second pressing heads 321 rotate to the relative positions, the first pressing head 221 and the second pressing heads 321 simultaneously extrude the core layer portion 200, so that the first pressing head 221 abuts against the third piston 331 through the core layer portion 200 and extrudes the third piston 331. While the third piston 331 is pressed, it extrudes the fourth elastic member 332. At the same time, the third piston 331 further extrudes the high-pressure fragrance in the inner cavity of the fourth chute 33, so that the high-pressure fragrance further extruded in the inner cavity of the fourth chute 33 enters the inner cavity of the fifth chute 34 through the fifth communication hole 36. The high-pressure fragrance further extruded in the inner cavity of the fifth chute 34 further enters the sixth communication hole 37. When one end of the fourth piston 341 enters the second through hole 323, at the same time, under the diastolic action of the fifth elastic member 342, the fourth piston 341 further moves upward in the fifth chute 34, so that the second annular groove 343 communicates with the sixth communication hole 37, enabling the high-pressure fragrance to be atomized by the atomizing nozzle. The atomized fragrance contacts the inner wall of the core layer convex portion 2002 through the second through hole 323.

[0067] Similarly, the second pressing head 321 abuts against the first piston 231 through the core layer portion 200 and continuously extrudes the first piston 231. While the first piston 231 is pressed, it extrudes the first elastic member 232. At the same time, the first piston 231 further extrudes the high-pressure fragrance in the inner cavity of the first chute 23, so that the high-pressure fragrance further extruded in the inner cavity of the first chute 23 enters the inner cavity of the second chute 24 through the second communication hole 26. The high-pressure fragrance further extruded in the inner cavity of the second chute 24 further enters the third communication hole 27. When one end of the second piston 241 enters the first through hole 223, at the same time, under the diastolic action of the second elastic member 242, the second piston 241 further moves downward in the second chute 24, so that the first annular groove 243 communicates with the third communication hole 27, enabling the high-pressure fragrance to be atomized by the atomizing nozzle. The atomized fragrance contacts the inner wall of the core layer concave portion 2001 through the first through hole 223.

[0068] Similarly, while the first pressing member 22 rotates, the first rotating member 29, the multiple first pressing heads 221 and the first movable member 281 cooperate to shape the surface layer portion 100. The first movable member 281 shapes the surface layer first convex portion 1001 under the diastolic action of the third elastic member 282, and the first pressing head 221 shapes the surface layer second convex portion 1002. While the second pressing member 32 rotates, the second rotating member 39, the multiple second pressing heads 321 and the second movable member 381 cooperate to shape the bottom layer portion 300. The second movable member 381 shapes the bottom layer first concave portion 3001 under the diastolic action of the sixth elastic member 382, and the second pressing head 321 shapes the bottom layer second concave portion 3002.

[0069] Finally, by rotating the first composite part 41 and the second composite part 42, the first protrusion 411 and the second protrusion 421 cooperate with each other to perform fixed-point pressing on the surface layer part 100, the core layer part 200, and the bottom layer part 300.

[0070] In summary, while the second pressing head 321 presses the core layer convex part 2002, atomized flavoring is performed on the inner cavity of the core layer convex part 2002. At the same time, while the first pressing head 221 presses the core layer concave part 2001, atomized flavoring is performed on the inner cavity of the core layer concave part 2001, thereby ensuring fixed-point flavoring of the tissue paper and preventing the flavor from quickly diffusing due to molecular diffusion and causing flavor mixing with other flavors. While the first pressing head 221 further presses the second movable part 381, the flavor liquid located in the fifth chute 34 is further pressed, so that the atomizing nozzle in the second piston 241 atomizes more thoroughly under high pressure. And while the first pressing head 221 further presses the second movable part 381, quantitative atomization of the perfume liquid in the fifth chute 34 into the perfume liquid in the second piston 241 is achieved, so that the atomized perfume adheres more evenly to the inner cavity of the core layer convex part 2002 that cooperates with it. Since the core layer part 200 is located in the middle, after the inner cavities of the plurality of core layer concave parts 2001 and the inner cavities of the plurality of core layer convex parts 2002 are atomized with perfume, the diffusion of the perfume can be blocked through the settings of the surface layer part 100 and the bottom layer part 300, so that the surface layer part 100 and the bottom layer part 300 are adhered by perfume molecules. By rotating the first composite part 41 and the second composite part 42, the first protrusion 411 and the second protrusion 421 cooperate with each other to perform fixed-point pressing on the surface layer part 100, the core layer part 200, and the bottom layer part 300. The first concave part 3001 at the bottom is adapted to the core layer concave part 2001, the first convex part 1001 on the surface is adapted to the core layer concave part 2001 and forms a first fragrance-fixing area, the second convex part 1002 on the surface is adapted to the core layer convex part 2002, and the second concave part 3002 at the bottom is adapted to the core layer convex part 2002 and forms a second fragrance-fixing area, ensuring the long-lasting fragrance of the fragrance-fixing tissue paper.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
