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.

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. The first pressing member 22 rotates counterclockwise and drives the first rotating member 29 to rotate clockwise. Similarly, the second pressing member 32 rotates clockwise and 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.

[0043] The machine is adjusted first, one end of the core layer 200 is placed between the first pressing piece 22 and the second pressing piece 32, the first pressing piece 22 rotates counterclockwise on the first fragrance fixing piece 21, and the second pressing piece 32 rotates clockwise on the second fragrance fixing piece 31. When the first pressing piece 22 and the second pressing piece 32 rotate, the first piston 231 slides in the first slide groove 23, and at the same time, one end of the first piston 231 slides in the third annular groove 224. When the first piston 231 slides in the third annular groove 224, the high-pressure fragrance in the first liquid inlet chamber 211 enters the inner cavity of the first slide groove 23 through the first connecting hole 25 and the one-way valve. Similarly, the third piston 331 slides in the fourth slide groove 33, and at the same time, one end of the third piston 331 slides in the fourth annular groove 324. When the third piston 331 slides in the fourth annular groove 324, the second liquid inlet chamber 3 The high-pressure spices in 11 enter the inner cavity of the fourth slide groove 33 through the fourth connecting hole 35 and the one-way valve, the high-pressure spices located in the inner cavity of the first slide groove 23 enters the inner cavity of the second slide groove 24 through the second connecting hole 26, the high-pressure spices located in the inner cavity of the second slide groove 24 contacts the second piston 241 through the third connecting hole 27, and since one end of the second piston 241 contacts the inner wall of the first pressing piece 22, the first annular groove 243 and the third connecting hole 27 are misaligned and not conductive. Similarly, the high-pressure spices located in the inner cavity of the fourth slide groove 33 enters the inner cavity of the fifth slide groove 34 through the fifth connecting hole 36, and the high-pressure spices located in the inner cavity of the fifth slide groove 34 contacts the fourth piston 341 through the sixth connecting hole 37. Since one end of the fourth piston 341 contacts the inner wall of the second pressing piece 32, the second annular groove 343 and the sixth connecting hole 37 are misaligned and not conductive.

[0044] As the first pressing member 22 and the second pressing member 32 rotate, when the first pressing head 221 and the plurality of second pressing heads 321 rotate to a relative position, the first pressing head 221 and the second pressing heads 321 simultaneously squeeze 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 squeezes the third piston 331, and the third piston 331 is compressed while squeezing the fourth elastic member 332, and at the same time, the third piston 331 further squeezes the high-pressure fragrance in the inner cavity of the fourth slide groove 33, so that the inner cavity of the fourth slide groove 33 is further compressed. The squeezed high-pressure fragrance enters the inner cavity of the fifth slide groove 34 through the fifth connecting hole 36, and the high-pressure fragrance further squeezed in the inner cavity of the fifth slide groove 34 further enters the sixth connecting hole 37. When one end of the fourth piston 341 enters the second through hole 323, and at the same time, under the relaxation effect of the fifth elastic member 342, the fourth piston 341 moves further upward in the fifth slide groove 34, so that the second annular groove 343 is connected with the sixth connecting hole 37, so that the high-pressure fragrance is atomized through the atomizing nozzle, and the atomized fragrance contacts the inner wall of the core layer protrusion 2002 through the second through hole 323.

[0045] Similarly, the second pressing head 321 is against the first piston 231 through the core layer part 200 and continuously squeezes the first piston 231. While the first piston 231 is under pressure, it squeezes the first elastic member 232. At the same time, the first piston 231 further squeezes the high-pressure fragrance in the inner cavity of the first slide groove 23, so that the high-pressure fragrance further squeezed in the inner cavity of the first slide groove 23 enters the inner cavity of the second slide groove 24 through the second connecting hole 26, and the high-pressure fragrance further squeezed in the inner cavity of the second slide groove 24 further enters the third connecting hole 27. When one end of the second piston 241 enters the first through hole 223, and under the relaxation effect of the second elastic member 242, the second piston 241 moves further downward in the second slide groove 24, so that the first annular groove 243 is connected with the third connecting hole 27, so that the high-pressure fragrance is atomized through the atomizing nozzle, and the atomized fragrance contacts the inner wall of the core layer recess 2001 through the first through hole 223.

[0046] Similarly, when the first pressing member 22 rotates, the first rotating member 29 cooperates with the multiple first pressing heads 221 and the first movable member 281 to shape the surface part 100, and the first movable member 281 shapes the first convex portion 1001 of the surface under the relaxation action of the third elastic member 282, and the first pressing head 221 shapes the second convex portion 1002 of the surface; when the second pressing member 32 rotates, the second rotating member 39 cooperates with the multiple second pressing heads 321 and the second movable member 381 to shape the bottom layer 300, and the second movable member 381 shapes the first concave portion 3001 of the bottom layer under the relaxation action of the sixth elastic member 382, ​​and the second pressing head 321 shapes the second concave portion 3002 of the bottom layer.

[0047] Finally, the first composite member 41 and the second composite member 42 are rotated so that the first protrusion 411 and the second protrusion 421 cooperate with each other, and the surface layer portion 100 , the core layer portion 200 and the bottom layer portion 300 are pressed at a fixed point.

[0048] In summary, the inner cavity of the core layer convex part 2002 is atomized and scented while the second pressing head 321 presses the core layer convex part 2002, and the inner cavity of the core layer concave part 2001 is atomized and scented while the first pressing head 221 presses the core layer concave part 2001, thereby ensuring the fixed-point scenting of the paper towel and preventing the rapid molecular diffusion of the fragrance from causing cross-flavor with other fragrances; while the first pressing head 221 further squeezes the second movable part 381, the fragrance liquid in the fifth slide groove 34 is further squeezed, so that the atomizing nozzle in the second piston 241 is atomized more thoroughly under the action of high pressure, and while the first pressing head 221 further squeezes the second movable part 381, the perfume liquid in the fifth slide groove 34 enters the perfume liquid in the second piston 241 for quantitative atomization, so that the atomized perfume is more evenly attached to the core layer convex part 2002 matched therewith. The core layer 200 is located in the middle, so that the inner cavities of the multiple core layer concave portions 2001 and the inner cavities of the multiple core layer convex portions 2002 atomize the perfume, and the surface layer 100 and the bottom layer 300 are arranged to block the diffused perfume, so that the surface layer 100 and the bottom layer 300 are attached by perfume molecules; the first composite member 41 and the second composite member 42 are rotated, so that the first protrusion 411 and the second protrusion 421 cooperate with each other, The layer portion 100, the core layer portion 200 and the bottom layer portion 300 are pressed at fixed points, the first concave portion 3001 of the bottom layer is matched with the concave portion 2001 of the core layer, the first convex portion 1001 of the surface layer is matched with the concave portion 2001 of the core layer and form a first fragrance fixing area, the second convex portion 1002 of the surface layer is matched with the convex portion 2002 of the core layer and form a second fragrance fixing area, so as to ensure that the fragrance of the fixed fragrance tissue is long-lasting.
