[0041] This utility model proposes a sticker machine for outputting stickers.

[0042] In this embodiment of the utility model, please refer to Figures 1 to 9 The sticker machine 100 includes:

[0043] The main body 10 has a sticker 32 outlet 11 and includes a receiving compartment 12 with an opening, the sticker 32 outlet 11 being connected to the receiving compartment 12;

[0044] A sticker roll 20 includes a backing paper 30 and multiple stickers 32 that are peelably adhered to the backing paper 30; the multiple stickers 32 are spaced apart along the length of the backing paper 30; each sticker 32 includes an adhesive layer 33, a release layer 34, and a microporous ink-receiving layer 35 stacked sequentially; the adhesive layer 33 is detachably adhered to the backing paper 30; the release layer 34 is used to prevent ink from penetrating to the adhesive layer 33; and the microporous ink-receiving layer 35 is used to fix the ink;

[0045] A paper roll support frame 40 is used to support the sticker roll 20, and the paper roll support frame 40 is replaceably mounted in the receiving compartment 12; the paper roll support frame 40 includes a connecting post 41 and a winding shaft 42, the connecting post 41 being used for mounting the sticker roll 20, and the winding shaft 42 being used for winding the backing paper 30 after the sticker 32 has been peeled off; and

[0046] A cover 50 is provided over the opening of the receiving compartment 12. The cover 50 is detachably connected to the main body 10 to confine the paper roll support frame 40 within the receiving compartment 12.

[0047] This application provides a sticker applicator 100 for outputting stickers 32. The stickers 32 are peelably adhered to a backing paper 30 and wound into a sticker roll 20. The sticker applicator 100 includes a main body 10, a cover 50, and a paper roll support 40. The main body 10 includes a receiving compartment 12 with an opening; the paper roll support 40 is used to hold the sticker roll 20 and is assembled in the receiving compartment 12; the cover 50 covers the opening of the receiving compartment 12 and is detachably connected to the main body 10 to confine the paper roll support 40 within the receiving compartment 12.

[0048] In the sticker machine 100 provided in this application, the paper roll carrier 40 does not serve as an external surface, but only as a carrier for the sticker roll 20 and an output of the sticker 32. Therefore, there is more room for choice in the materials used to manufacture the paper roll carrier 40, and the manufacturing precision of the paper roll carrier 40 can be reduced, thereby reducing costs. When the sticker roll 20 is used up, the cover 50 is opened to replace the new paper roll carrier 40, and then the cover 50 is closed again. The cover 50 is used as part of the external components for a long time without being replaced, which reduces the number of parts that need to be replaced when the sticker roll 20 is replaced, further reducing the operating costs.

[0049] In this embodiment, the main body 10 includes an outer shell and a bottom shell. The outer shell includes a peripheral side wall and a partition wall. A sticker 32 outlet 11 is provided on the peripheral side wall. The partition wall is disposed between the upper edge and the lower edge of the peripheral side wall to enclose the receiving compartment 12 located above the partition wall and the driving compartment located below the partition wall. A driving mechanism for driving the winding shaft 42 to rotate is installed in the driving compartment. The bottom shell is covered by the lower edge of the peripheral side wall.

[0050] In the sticker machine 100 provided in this application, the sticker roll 20 is the core component of the solution. Each sticker 32 is sequentially assembled on the backing paper 30 and bonded to the backing paper 30 by the adhesive layer 33, facilitating subsequent peeling and use. The stickers 32 are spaced apart along the length of the backing paper 30 to ensure that each sticker 32 is independent and neat, making it easy to peel off one by one.

[0051] Sticker 32 can be made of PP synthetic paper. After surface treatment, it has good printability and tear resistance, and is also water-resistant, heat-resistant and weather-resistant.

[0052] The sticker 32 has a multi-layer structure, including an adhesive layer 33, a release layer 34, and a microporous ink-coating layer 35. The adhesive layer 33 is located on the surface of the sticker 32 and is used to adhere the backing paper 30, ensuring that the sticker 32 does not fall off during storage, but can be separated by a specific peeling method.

[0053] The adhesive layer 33 can be made of a removable acrylic pressure-sensitive adhesive with suitable initial tack and high resilience, exhibiting excellent wetting ability on the surface of the object to which it is applied. This allows for repeated peeling and pasting on various non-paper materials without leaving any residue. Consequently, the sticker 32 can be peeled off from the surface of various non-paper materials without leaving any adhesive residue.

[0054] An isolation layer 34 is disposed between the adhesive layer 33 and the microporous inking layer 35. On the one hand, the isolation layer 34 effectively prevents ink from penetrating into the adhesive layer 33, maintaining a stable distribution of ink on the surface of the microporous inking layer 35, thereby ensuring clear and uniform printing quality of the sticker 32. Simultaneously, it protects the adhesive properties and the integrity of the sticker 32, guaranteeing the quality of adhesion. On the other hand, as the base layer of the sticker 32, the isolation layer 34 possesses a certain degree of flexibility and strength, helping the sticker 32 withstand mechanical stress and tension during use, preventing cracking or damage. The isolation layer 34 can be made of polyester (PET), multilayer composite film, or special polymer film with excellent barrier properties; no specific limitations are imposed here.

[0055] The microporous ink-retaining layer 35 enhances the ink's fixation ability, allowing the ink to better embed itself in the microporous structure, thereby improving ink adhesion and abrasion resistance, and preventing blurring / spreading of the print after finger contact or paper friction. Manufacturers can print on the microporous ink-retaining layer 35, and users can write or draw on it. For example, after printing a design on the microporous ink-retaining layer 35, users can write annotations or fill in colors on the sticker 32; or a design can be printed on the microporous ink-retaining layer 35 with a lighter ink color, and users can trace the outline of the design; or only a portion of the design can be printed on the microporous ink-retaining layer 35, allowing users to further create based on it. The design can be text, cartoon characters, animals, or fruits, etc., and is not limited thereto.

[0056] The microporous ink-coating layer material can be a porous polymer material (such as polypropylene (PP), polyurethane (PU)), a ceramic-based porous material, or a composite material prepared from these basic materials, and is not limited here.

[0057] This application provides a sticker printer 100, which allows users to write, trace, and create on stickers 32 through a microporous ink layer 35; the isolation layer 34 and the microporous ink layer 35 enable writing and printing on the stickers 32, ensuring that the ink adheres stably and clearly to the stickers 32, preventing the writing from "bleeding" or "fading" due to touch or friction. Simultaneously, the sticker printer 100 has a replaceable paper roll support 40 and a detachable cover 50, greatly facilitating the replacement, maintenance, and operation of the stickers 32.

[0058] Furthermore, the isolation layer 34 is made of a tear-resistant material. The isolation layer 34 can be made of a high-strength tear-resistant material, such as polypropylene (and its composites), high-strength polyester film (such as PET film), or microfiber composite material. The specific material used is not limited herein.

[0059] This gives the release layer 34 excellent tensile strength and tear resistance, ensuring that the release layer 34 will not tear or break when the sticker 32 is peeled off, during repeated operations or when it is subjected to mechanical impact, thereby maintaining its function of blocking ink penetration and the integrity of the overall structure.

[0060] In one embodiment, the isolation layer 34 is made of a hydrophobic material. In this embodiment, a hydrophobic coating can be applied to the surface of the isolation layer 34, such as a coating containing silane, fluoroalkyl compounds, or other hydrophobic agents, to form a hydrophobic layer. Alternatively, plasma technology or nanotechnology can be used to modify the surface microstructure and enhance the hydrophobic properties. After hydrophobic treatment, the isolation layer 34 maintains good surface smoothness and adhesion, without affecting subsequent printing processes. After printing, its hydrophobic properties continue to effectively prevent the penetration of moisture or liquid ink, thereby enhancing the waterproof and stain-resistant properties of the sticker 32 and ensuring the long-term preservation of the printed pattern.

[0061] In one embodiment, the insulating layer 34 has both tear resistance and hydrophobic properties. Thus, the sticker 32 is neither easily torn nor does it need to be waterproof.

[0062] In one embodiment, the microporous ink-adhesive layer 35 is coated with a quick-drying coating 36 on the side opposite to the adhesive layer 33 to prevent ink smudging.

[0063] In related technologies, writing on paper can cause ink bleeding. In this embodiment, the fast-drying coating 36 can be selected from coatings with rapid drying properties, such as acrylic, silane-modified resins, or water-based fast-drying coatings. This avoids solvent residue during ink drying that could cause edge bleeding and ink droplet diffusion, effectively preventing ink from flowing and spreading along the layer edges during printing, handling, and use, ensuring clear pattern outlines and avoiding smudging.

[0064] The fast-drying coating can be a hydrophilic fast-drying coating, a low surface energy fast-drying coating, or a composite coating, and there is no limitation on it.

[0065] In one embodiment, the surface of the microporous ink layer 35 is coated with a smooth coating 37, the roughness of which is less than that of the microporous ink layer 35.

[0066] In this embodiment, the smooth coating 37 can be selected from polymer resins or silane materials, giving the sticker 32 surface good adhesion and leveling properties. In other words, this coating can form a smooth and uniform surface on the sticker 32. Combined with the microporous ink-adhesive layer 35, this coating allows the ink to adhere clearly and stably to the surface of the sticker 32, preventing the ink from blurring / smudging due to contact or friction. It also reduces frictional resistance in the conveying path within the sticker machine 100, preventing slow paper output or paper jams. The smooth coating 37 can be formed by coating with polyurethane, acrylate, etc., and is not limited thereto.

[0067] In one embodiment, the sticker roll 20 includes a plurality of sticker groups 31 arranged sequentially, each sticker group 31 having a plurality of stickers 32; the sticker group 31 includes at least two of the following: pattern reference sticker 321, pattern overall tracing sticker 322, pattern partial tracing sticker 32, and pattern filling sticker 32.

[0068] In this embodiment, the pattern reference sticker 321 provides a reference for the complete pattern, helping users to learn or imitate by comparison, which helps in training and mastering skills.

[0069] The 322 pattern tracing sticker provides complete patterns to help users identify outlines and improve drawing accuracy.

[0070] Compared to the pattern reference sticker 321, the pattern on the overall pattern tracing sticker 322 is lighter in color, which makes it easier for users to clearly see what they are writing when tracing, distinguishing it from the printed lines, without obscuring or affecting the details of the writing.

[0071] The 32-piece pattern tracing sticker set only provides partial patterns for tracing, suitable for detail training or practice of key areas. (Note: Tracing refers to a learning method in which one imitates or copies printed characters or lines (such as red lines on calligraphy practice books) to practice writing or drawing skills.)

[0072] Pattern Fill Sticker 32 provides patterns for incomplete, blank, or missing parts, encouraging users to fill in the blanks and exercise their observation and creativity.

[0073] Combining different types of stickers 32 within a sticker set 31 helps to progressively train skills or create designs, meeting different learning stages and practical needs. For example, a sticker set 31 may first provide a complete pattern for reference, and then gradually set up overall pattern tracing stickers 322, partial pattern tracing stickers 32, and pattern filling stickers 32, guiding the user step by step to complete the pattern.

[0074] Furthermore, the pattern filling sticker 32 includes at least a first pattern filling sticker 323 and a second pattern filling sticker 324, with the number of pattern elements decreasing sequentially.

[0075] In this embodiment, the first pattern-filling sticker 323 provides a relatively complete pattern, containing numerous elements and details, suitable for beginner users to reference and imitate. The second pattern-filling sticker 324, building upon the first level, reduces the number of elements or simplifies details, increasing the difficulty for users to fill in the blanks and cultivating their observation and imagination abilities. This gradual reduction in the completeness of the pattern helps users gradually master the details, enhances their observation and detail-capturing abilities, and guides them from dependence and imitation to independent creation.

[0076] In one embodiment, the paper roll carrier 40 further includes a sticker 32 conveying section and a turning and peeling section 44; wherein, the sticker 32 conveying section is disposed between the socket post 41 and the turning and peeling section 44 to convey the sticker 32 to the turning and peeling section 44; the turning and peeling section 44 is disposed between the sticker 32 conveying section and the winding shaft 42 to convey the backing paper 30 in a direction different from the travel direction of the sticker 32 so that the sticker 32 is peeled off from the backing paper 30; the side of the sticker 32 conveying section facing the sticker 32 is a smooth surface.

[0077] In this embodiment, in the conveying direction of the sticker 32, the sticker 32 conveying part is disposed between the socket post 41 and the turning peeling part 44 to convey the sticker 32 to the turning peeling part 44; the turning peeling part 44 is disposed between the sticker 32 conveying part and the winding shaft 42 to convey the backing paper 30 in a direction different from the traveling direction of the sticker 32 so that the sticker 32 is peeled off from the backing paper 30.

[0078] The side of the sticker 32 conveying section facing the sticker 32 is a smooth surface. This smooth surface has a low coefficient of friction. As the sticker 32 passes through this surface along the conveying path, the friction is significantly reduced, minimizing resistance caused by friction and ensuring a smooth flow of the sticker 32 as it leaves the sticker 32 conveying section and enters the turning and peeling section 44. Simultaneously, this smooth surface also prevents the surface of the sticker 32 from being scratched or abraded.

[0079] Furthermore, the paper roll support frame 40 also includes an upper cover plate 45 and a lower cover plate 46 disposed opposite to each other; the sticker 32 conveying part, the turning and peeling part 44, the socket post 41 and the winding shaft 42 are disposed between the upper cover plate 45 and the lower cover plate 46;

[0080] The edges of the upper cover plate 45 and the lower cover plate 46 are open, and the sticker roll 20 sleeved on the sleeve post 41 is spaced apart from the inner side wall of the receiving compartment 12 inside the main body 10.

[0081] In this embodiment, only the discretely distributed socket posts 41, winding shaft 42, sticker 32 conveying section, turning and peeling section 44, and mounting posts are provided between the upper cover plate 45 and the lower cover plate 46, without a continuous wall. This makes the paper roll carrier 40 simple in structure, uses less material, and is inexpensive. Since the paper roll carrier 40 itself does not have a continuous wall or a cavity, the friction between the sticker 32 surface and the paper roll carrier 40 is reduced, reducing the resistance caused by friction, allowing the sticker 32 to be conveyed out faster and more smoothly.

[0082] Furthermore, the upper cover plate 45 and / or the lower cover plate 46 are provided with calibration holes 161, through which the sticker roll 20 is exposed for adjustment. In this embodiment, the calibration hole 161 provides an intuitive interface, allowing the operator to directly observe and manipulate the exposed sticker roll 20, quickly achieving fine-tuning of the sticker roll 20's tension and reducing traditionally cumbersome adjustment steps.

[0083] Furthermore, the projection of the calibration hole 161 on the upper cover plate 45 and / or the lower cover plate 46 is located between the sleeve post 41 and the winding shaft 42.

[0084] In this embodiment, the projection position of the calibration hole 161 is set between the sleeve post 41 and the winding shaft 42, which effectively utilizes the original structural area without adding extra space, making the mechanism of the paper roll carrier 40 more compact.

[0085] The sticker outlet 11 of the sticker machine 100 can output only one sticker 32 at a time, and can also change the width of the backing paper so that multiple stickers 32 are distributed along the width direction, thereby enabling the sticker outlet 11 to output multiple stickers 32 at a time.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
