Description

Technical Field

[0001] This application relates to the field of daily necessities, specifically to a sticky roller and a sticky device. Background Technology

[0002] Sticky rollers are a common household cleaning tool used to remove dust and lint from surfaces such as clothing, sheets, carpets, floors, and furniture. A typical structure includes a core and multiple layers of sticky paper wrapped around its outer surface. During use, the user holds the roller handle and rolls it over the surface to be cleaned. The stickiness of the paper attracts the dust. Once the outer layer of sticky paper is covered in dust, it can be peeled off to expose the inner layer for continued use. It is simple and convenient to operate.

[0003] However, when cleaning smooth surfaces (such as glass, glossy furniture, floors, etc.) with existing sticky rollers, the sticky paper often sticks to the surface being cleaned, causing the sticky roller to be unable to roll freely, or even causing the sticky paper to fall off and stick to the surface being cleaned, which is difficult to remove, causing a lot of inconvenience to users.

The first side and the second side are respectively flush with the two ends of the axial direction of the core. The acute angle connecting the first side and the third side is the starting end of the winding, and the acute angle connecting the second side and the fourth side is the ending end of the winding. The glue-free area extends along the fourth side to the second side.

[0011] According to one aspect of this application, the length of the first side and the second side is L1, the length L1 being greater than or equal to the circumference of the wound paper roll, such that the outer bevel of each sheet of adhesive paper overlaps the inner bevel.

[0012] According to one aspect of this application, the outer diameter of the core is d0, the axial height of the core is h, and the width W0 of each adhesive paper is equal to the distance between the third side and the fourth side.

[0016] According to one aspect of this application, each x adjacent sticky sheets have the same shape and size, wherein the first to the xth sticky sheets adopt the size of the first sticky sheet, the (x+1)th to the 2xth sticky sheets adopt the size of the (x+1)th sticky sheet, and so on, where x is an integer greater than or equal to 2.

[0017] According to one aspect of this application, in the adhesive layer of each adhesive sheet, a plurality of adhesive strips and a plurality of spacers are disposed on the same layer, adjacent adhesive strips are separated from each other by spacers, or a plurality of adhesive strips are connected to each other to form a planar shape, and a plurality of spacers are formed on the outer surface of the adhesive strips.

[0031] Embodiments of this application provide a dust-removing roller that can clean dust without sticking to the surface being cleaned and affecting normal use.

[0032] like Figure 1 As shown, the adhesive roller provided according to the embodiments of this application includes a core 200 and multiple sheets of adhesive paper 100, which are spirally wound around the core 200 in sequence. Each sheet of adhesive paper 100 is wound independently. After the outer layer of adhesive paper is covered with dust, the outer layer of adhesive paper can be peeled off to expose the inner layer of new, clean adhesive paper. It is convenient to use and simple to operate.

[0033] Figure 2 A schematic diagram shows the unfolded state of a single sheet of adhesive paper 100. (See diagram.) Figure 2 As shown, the adhesive paper 100 is roughly parallelogram-shaped. Figure 3 and Figure 4 A cross-sectional view of the adhesive paper is shown, as follows. Figure 3 and Figure 4 As shown, the adhesive paper 100 includes a base layer 110 and an adhesive layer 120 disposed on the base layer 110. The base layer 110 has a first surface and a second surface facing each other, and the adhesive layer 120 is disposed on the first surface. The adhesive layer 120 has adhesive force. When each sheet of adhesive paper 100 is wound around the core 200, the adhesive layer 120 faces outward, thereby being able to contact the surface being cleaned and adhere to dust and impurities. The second surface of the base layer 110 faces the core 200 and does not have adhesive force, serving as the peel surface between adjacent layers of adhesive paper. When the outer layer of adhesive paper 100 becomes covered with dust and its adhesive force decreases, the outer layer of adhesive paper can be easily peeled off, exposing the clean inner layer of adhesive paper.

[0034] When multiple sheets of adhesive paper 100 are wound layer by layer, the second surface of the base layer 110 of the outer adhesive paper can overlap and contact the adhesive layer 120 of the inner adhesive paper. Since the adhesive layer 120 has adhesive force, it can bond with the second surface of the base layer 110, ensuring that the adhesive roller can be wound tightly and preventing unwinding.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the adhesive layer 120 includes multiple adhesive strips 121 and multiple release strips 122, which are alternately arranged. The adhesive strips 121 are made of adhesive and are sticky, with their exposed surfaces serving as the adhesive surface for sticking to dust. The release strips 122 are not sticky or have relatively low stickiness, which reduces the area of ​​the adhesive layer 120 directly adhering to the surface being cleaned. This facilitates the separation of the adhesive paper 100 from the surface being cleaned, allowing the adhesive roller to roll freely on the surface being cleaned. Therefore, it can be used on any surface that needs cleaning, exhibiting high versatility.

[0036] Figure 3 The diagram shown is a cross-sectional view of the adhesive paper according to the first embodiment of this application. Figure 3 As shown, the adhesive layer 120 can be formed as a single layer, and the adhesive strips 121 are multiple separate strips separated from each other by separator strips 122. The exposed surfaces of the adhesive strips 121 between adjacent separator strips 122 are the adhesive surfaces, serving as the working surfaces for adsorbing dust and impurities. Figure 3 The single-layer structure shown can be formed in one step by simultaneously applying two different adhesives to the base layer 110 using an adhesive applicator, along with the adhesive strip 121 and the spacer strip 122. The adhesive strip 121 and the spacer strip 122 can be arranged in parallel strips or in a wavy shape, as long as the adhesive strip 121 is separated from each other.

[0037] Figure 4 The diagram shown is a cross-sectional view of the adhesive paper according to a second embodiment of this application. Figure 4 As shown, the adhesive layer 120 can be formed as a two-layer structure. Adhesive strips 121 serve as the first layer and can be interconnected to form a continuously distributed planar shape. Separator strips 122 serve as the second layer and are formed on the outer surface of the adhesive strips 121. The area of ​​the first layer of adhesive between adjacent separator strips 122 is the adhesive surface. As an example, to form the two-layer adhesive layer 120, the first layer of adhesive can be applied to the base layer 110 using an adhesive applicator, and then the separator strips 122 can be applied onto the first layer of adhesive.

[0038] In the example shown in the attached figure, the separator strips 122 are parallel lines extending along the length of the adhesive paper 100 and spaced apart from each other in the width direction. By setting the adhesive strips 121 and 122 to extend in the same direction as the length of the adhesive paper 100, the adhesive strips 121 and 122 can be laid along the length of the raw paper when making the adhesive paper 100. This facilitates the continuity and smoothness of the adhesive application equipment, resulting in a more uniform and aesthetically pleasing coating width and thickness for the adhesive strips 121 and 122. Furthermore, the continuity of the coating process also makes the manufacturing process more convenient and simpler.

[0039] According to embodiments of this application, the material constituting the adhesive strip 121 can be a commonly used adhesive in the prior art, such as acrylic adhesive, rubber adhesive, polyester adhesive, etc. The initial tack is equivalent to a 5# to 10# steel ball, the peel force is 0.1 to 0.2 N, and the unwinding force is 0.08 N to 0.2 N. The material constituting the release strip 122 can be a viscoelastic material, such as an acrylic-based viscoelastic material.

[0040] exist Figure 3 In the exemplary structure shown, the thickness of the adhesive strip 121 can be set to 8~15µm, and the separating strip 122 can protrude outwards by 30~100µm relative to the adhesive strip 121. Of course, in Figure 3 In the structure shown, the outer surface of the isolation strip 122 can be flush with the outer surface of the adhesive strip 121. The thickness of the base layer 110 can be set to 50~60µm.

[0041] The width of the isolation strip 122 is not particularly limited and can be designed according to the material and surface condition of the surface to be cleaned, as well as the initial adhesion of the adhesive strip 121. For example, the width of the isolation strip 122 can be set to 1mm-3mm, with intervals of 3mm-5mm.

[0042] According to the embodiments of this application, the adhesive paper 100 is spirally wound layer by layer onto the core 200. The continuous layered structure formed by the spiral winding makes each layer of adhesive paper 100 physically independent. When the outer layer of adhesive paper is peeled off, the inner layer of adhesive paper will not be torn apart, ensuring the tightness of the inner layer of adhesive paper and not affecting subsequent adhesive application. In addition, the spiral winding method can form a structure similar to a "spiral reinforcing rib" on the core 200, which helps to improve the rigidity and stability of the entire adhesive roller under rolling pressure, preventing excessive deformation of the core 200 or loosening and collapse of the paper roll. Especially when using high-pressure cleaning, it can also ensure that the adhesive roller rolls freely without collapsing.

[0043] In order for the adhesive paper 100 to spirally wrap around the core 200 and completely cover the outer surface of the core 200, the adhesive paper 100 is as follows: Figure 2 The parallelogram shown is a shape where opposite angles are acute. For example... Figure 2 As shown, the parallelogram has four sides, namely the opposite first side 101, the second side 102, the opposite third side 103, and the fourth side 104. Figure 5 As shown, when spirally wound around the core 200, the first side 101 and the second side 102 are flush with the two ends of the axial direction of the core 200, while the third side 103 and the fourth side 104 spirally wound around the core 200.

[0044] According to an embodiment of this application, in order to achieve a tighter winding, a single sheet of adhesive paper 100 can be wound more than one turn around the core 200. According to an embodiment of this application, the width of the adhesive paper 100 is less than the axial height h of the core 200, and the length of a single sheet of adhesive paper 100 is greater than the circumference of the core 200. Therefore, each sheet of adhesive paper 100 can be wound approximately 2-3 turns around the core 200, resulting in a tight winding and preventing unraveling.

[0045] When each sheet of adhesive paper 100 is wound obliquely around the core 200, adjacent oblique edges can be joined together without gaps, preventing dust from contaminating the inner adhesive paper through gaps between adjacent oblique edges during the dust-adhesive paper application. According to an embodiment of this application, to further ensure no gaps between adjacent oblique edges, the oblique edge of the outer ring of adhesive paper overlaps the oblique edge of the inner ring of adhesive paper with a certain overlap width, thus ensuring that the boundaries of the spirally wound outer layer of adhesive paper overlap without gaps, preventing the inner layer of adhesive paper from being exposed.

[0046] Figure 5 This diagram illustrates the outermost layer of adhesive paper in a partially unfolded state. Assume the currently wrapped outermost layer of adhesive paper is the nth sheet, wrapped around a roll of paper obtained after wrapping n-1 sheets of adhesive paper, where n is an integer greater than or equal to 1. Figure 5 As shown, the dashed line represents the top edge of the first wrap of the nth adhesive paper, corresponding to the third side 103 of the parallelogram. The bottom edge of the second wrap (corresponding to the fourth side 104 of the parallelogram) overlaps the top edge of the first wrap, avoiding gaps between them and preventing the (n-1)th adhesive paper from being exposed. As an example, the overlap width 'a' between two adjacent wraps of adhesive paper can be 2mm-5mm.

[0047] As an example, when each sheet of adhesive paper 100 is wound around the core 200, the first side 101 of the parallelogram is flush with the bottom of the core 200, and the fourth side 104 of each sheet of adhesive paper 100 overlaps the third side 103. After winding, the second side 102 of the parallelogram is flush with the top of the core 200. Thus, a single sheet of adhesive paper 100 completely covers the outer surface of the core 200.

[0048] According to the dust-adhesive roller of this application, the oblique winding method of layering and pressing can prevent the outer dust-adhesive paper from contaminating the inner dust-adhesive paper during the dust adhesion process, thereby ensuring that after the outer dust-adhesive paper is peeled off, a clean new dust-adhesive paper is exposed inside, which does not affect the effect and quality of subsequent dust-adhesive operations.

[0049] In order for the adhesive paper 100 to be wound in an edge-overlapping manner, the length L1 of the first side 101 of the parallelogram needs to be greater than the circumference s of the currently wound paper roll. The symbol b represents the amount by which L1 is greater than s, and the value of b can be 2mm-5mm.

[0050] Assume the outer diameter of the core is d0, the axial length is h, and the thickness of each sheet of adhesive paper 100 is t, corresponding to the thickness of the area where the adhesive layer 120 is located. As the number of sheets of adhesive paper 100 increases, the diameter of the paper roll continuously increases. Let d represent the outer diameter of the paper roll after winding n-1 sheets of adhesive paper 100, then the outer diameter of the paper roll obtained after winding n-1 sheets of adhesive paper 100 is d = d0 + 2(n-1)t, and the circumference of the paper roll is s = πd = π*(d0 + 2(n-1)t). The length L1 of the first side 101 of the nth sheet of adhesive paper needs to be greater than s to ensure that the hypotenuse of the outer sheet of adhesive paper overlaps the hypotenuse of the inner sheet of adhesive paper. As mentioned before, let parameter b represent the length of L1 greater than s, then L1 = s + b = π*(d0 + 2(n-1)t) + b, where n is an integer greater than or equal to 1.

[0051] When each sheet of adhesive paper 100 is wound, the acute angle connecting the first side 101 and the third side 103 serves as the starting end 105 of the winding, and the acute angle connecting the second side 102 and the fourth side 104 serves as the ending end of the winding. After each sheet of adhesive paper 100 is wound, the starting end 105 is folded inside by the outer layer of adhesive paper, while the ending end is exposed on the outside. Therefore, the ending end can serve as the peeling head 106, serving as the starting part for peeling off that sheet of adhesive paper. When the adhesive paper 100 is covered with dust, the user can easily peel off the adhesive paper 100 starting from the peeling head 106. Figure 6 This diagram shows the peeling head of the outer adhesive paper in the peeling state.

[0052] However, when the outer surface of the peeling head 106 is also coated with adhesive, the peeling head 106 is less distinguishable from other areas in appearance, making it difficult for users to identify its location and locate. Furthermore, when users pinch the peeling head 106, the adhesive tends to stick to their hands, resulting in a poor user experience. Therefore, according to embodiments of this application, at least in the area of ​​the peeling head 106, no adhesive layer 120 is provided.

[0053] like Figure 2 , Figure 5 and Figure 6 As shown in the embodiment of this application, the adhesive layer 120 is disposed in a portion of the base layer 110, not completely covering the base layer 110, thereby creating a non-adhesive area 130 on one side of the adhesive layer 120, in which no adhesive is disposed. The non-adhesive area 130 extends at least to the area where the peeling head 106 is located. Since no adhesive is disposed in the non-adhesive area 130, the base layer 110 is exposed, making it visually distinct from the adhesive area where the adhesive layer 120 is located. Users can easily identify the position of the peeling head 106, and when tearing off the adhesive paper 100, the user's hand will not be stuck with adhesive, thereby improving the user experience.

[0054] According to an embodiment of this application, the adhesive-free area 130 can be disposed along the fourth side 104 and can extend to the second side 102. The adhesive-free area 130 can extend along the entire fourth side 104 to simplify the manufacturing process of the raw paper roll for the adhesive paper 100. As an example, such as... Figure 2 As shown, the adhesive layer 120 and the adhesive-free area 130 are arranged side by side. The width of the adhesive layer 120 is W1, and the width of the adhesive-free area 130 is W2. Therefore, W0 = W1 + W2. As an example, W2 can be 8mm-10mm.

[0055] According to the embodiments of this application, a non-adhesive area 130 is provided only on one side of the adhesive paper 100. While ensuring that the peeling head 106 is not sticky, the area of ​​the adhesive layer 120 in a single sheet of adhesive paper 100 can be increased, the effective working area of ​​a single sheet of adhesive paper 100 can be increased, and it is also beneficial for the adhesive paper 100 to be tightly wound and not unwound.

[0056] In the embodiments of this application, the adhesive-free area 130 is set along the fourth side 104 of the parallelogram. When the adhesive paper 100 is wound, the acute angle end where the first side 101 and the third side 103 intersect serves as the starting end 105 of the winding, while the acute angle end where the second side 102 and the fourth side 104 intersect serves as the ending end of the winding. This makes the end of the peeling head 106 a adhesive-free area, which is convenient for identifying the position of the peeling head 106 during peeling. Furthermore, because it does not come into contact with the adhesive, it will not stick to the hands, thus improving the user experience.

[0057] Since the adhesive-free area 130 lacks adhesive, the back of the outer adhesive paper faces the adhesive-free area 130 of the inner adhesive paper, preventing the formation of an adhesive bond between them. This affects the tightness of the paper roll winding. Consequently, if the adhesive-free areas 130 of two adjacent adhesive paper layers overlap, they cannot bond tightly at the overlap position, causing the adhesive paper to easily unwind. Furthermore, the overlapping area of ​​the adhesive-free areas 130 is thinner than the overlapping area of ​​the adhesive layer 120, resulting in uneven thickness of the adhesive roller and making it prone to wrinkling and deformation.

[0058] To prevent the adhesive paper roll from easily unraveling and to ensure that the winding thickness of the adhesive roller is as uniform as possible, according to embodiments of this application, such as... Figure 7 As shown, when the adhesive paper 100 is wound on the core 200, the non-adhesive areas 130 of two adjacent adhesive papers 100 are completely staggered, so that the adhesive layer 120 area of ​​the outer adhesive paper covers the non-adhesive area 130 of the inner adhesive paper, thereby improving the winding tightness of the adhesive paper and the thickness uniformity of the adhesive roller.

[0059] To ensure that the adhesive-free areas 130 of two adjacent adhesive sheets 100 are staggered, the starting ends 105 of the winding of two adjacent adhesive sheets 100 are staggered by a certain distance in the circumferential direction of the core 200. This distance is at least greater than the width of the adhesive-free area 130 in the circumferential direction of the currently wound paper roll, thereby preventing the adhesive-free areas 130 of two adjacent adhesive sheets 100 from overlapping, especially preventing the peeling head 106 areas of two adjacent adhesive sheets from overlapping each other, and preventing the adhesive at the peeling head 106 from being loose, causing the paper roll to unravel. The width of the adhesive-free area 130 in the circumferential direction of the paper roll is 8-10mm. As an example, the staggered distance can be set to be greater than or equal to 15mm.

[0060] like Figure 8 As shown, when the starting ends of the wrapping of two adjacent adhesive sheets are staggered, the peeling heads 106 of the two adjacent adhesive sheets will also be staggered accordingly. The peeling head of the outer adhesive sheet can overlap with the bonding area of ​​the inner adhesive sheet, and the outer peeling head can be adhered by the inner adhesive layer, preventing the peeling head from opening. Therefore, according to the embodiments of this application, the problem of peeling heads 106 being loose due to the lack of adhesion in the area of ​​the peeling head 106 is prevented from being peeled off when the peeling heads 106 without adhesive are overlapped is solved.

[0061] As the adhesive paper 100 is wound layer by layer, the diameter of the paper roll continuously increases, and the outer surface area also increases, requiring adaptive adjustments to the shape and area of ​​the adhesive paper 100. In existing technology, during the manufacturing of adhesive rollers, multiple raw paper rolls of different widths need to be wound onto the core 200 to meet the adjustment requirements for the shape and area of ​​each adhesive paper 100. However, the appearance of the raw paper rolls is usually not very distinctive, and workers are prone to mixing them up during installation, leading to a complex process, a high error rate, and impacting production efficiency and yield.

[0062] According to the embodiments of this application, the width W0 of the multiple adhesive paper 100s is the same, that is, the distance between the third side 103 and the fourth side 104 of the parallelogram is the same. Therefore, in the process of manufacturing the adhesive roller, a raw material paper of the same specification can be used to wind the roller to obtain an adhesive roller with multiple adhesive paper 100s of different shapes and areas, without having to use and change raw material paper of different specifications, which simplifies the production process and can improve production efficiency.

[0063] According to the embodiments of this application, each adhesive paper 100 is a parallelogram. The lengths of two adjacent sides of the parallelogram may not be equal. For example, the lengths of the first side 101 and the second side 102 are L1, and the lengths of the third side 103 and the fourth side 104 are L2. L2 can be set to be greater than L1. The width of the adhesive paper 100 is W0, that is, the distance between the third side and the fourth side is W0, which also corresponds to the width of the raw material paper.

[0064] Since the first side 101 and the second side 102 of each adhesive paper 100 are flush with both ends of the core 200, the distance between the first side 101 and the second side 102 is equal to the axial length h of the core 200. For multiple adhesive papers 100, the distance h between the first side 101 and the second side 102, and the distance W0 between the third side 103 and the fourth side 104, are fixed values. In order to adaptively adjust the shape and size of the adhesive paper 100 as the diameter of the paper roll changes during the winding process of the adhesive roller, the dimensions of the parallelogram need to be adjusted accordingly, that is, the side length L1 and the angle θ need to be adjusted accordingly.

[0065] Let's assume the angle between the first side 101 and the third side 103 is θ. To facilitate the calculation of the parallelogram's angles and side lengths L1 and L2, in... Figure 9 If right triangles are taken along W0 and h in the parallelogram shown, then the dimensional parameters of the nth adhesive paper 100 satisfy the following formula: (1) (2) (3) (4) Where t represents the thickness of a single sheet of adhesive paper 100, b represents the length margin of the first side 101 of the adhesive paper 100 when it wraps around the current paper roll, d0 represents the outer diameter of the core 200, d represents the outer diameter of the paper roll when the nth sheet of adhesive paper is wrapped, corresponding to the outer diameter of the paper roll obtained after wrapping n-1 sheets of adhesive paper 100, h represents the axial height of the core, L1 represents the length of the short side of the parallelogram, and L2 represents the length of the long side of the parallelogram. The acute angle of the parallelogram is represented by , and W0 represents the width of the sticky paper 100, where n is an integer greater than or equal to 1.

[0066] Given d0, b, n, h, and W0, we can determine equation (2) from equation (1), thus determining the size of the shorter side L1 of the parallelogram. Furthermore, we can determine the angle of the parallelogram from equation (3). Based on the shorter side L1 and the angle It can determine the winding angle of each sheet of raw paper on the core 200, so that the winding angle can be adjusted according to the thickness of the paper roll, and the winding equipment can be controlled accordingly.

[0067] Based on the determined axial length h of the core 200 and equations (3) and (4), the size of the long side L2 of the parallelogram can be further determined.

[0068] Therefore, according to the embodiments of this application, the side length and angle θ of each sheet of adhesive paper 100 can be determined, so that the shape and size of each sheet of adhesive paper 100 can be adapted to the size of the adhesive paper roller without changing the specifications of the raw material paper, thereby simplifying the production process.

[0069] According to an embodiment of this application, when the size of the adhesive paper 100 is determined, since the width W2 of the adhesive-free area 130 is preset as needed, the width of the adhesive-free area 130 of each adhesive paper 100 in the circumferential direction of the core 200 can be determined based on the size of the acute angle of the parallelogram. This allows for the determination of the minimum spacing between the peeling heads 106 of adjacent adhesive papers. As long as the circumferential spacing between the peeling heads 106 of adjacent layers is greater than the circumferential width of the adhesive-free area 130 of the outer layer adhesive paper, overlapping of the peeling heads 106 of adjacent adhesive papers can be avoided, ensuring the tightness of the adhesive paper 100 winding and preventing the paper roll from unraveling. Since the back side of the peeling head 106 of each adhesive paper 100 faces and is adhered to the adhesive area of ​​the inner layer adhesive paper, the inner layer adhesive paper 100 will not be torn off when the peeling head of the outer layer adhesive paper is peeled off, thus avoiding continuous tearing.

[0070] Because the thickness of the adhesive paper 100 is relatively small, the winding diameter of adjacent adhesive papers 100 differs little. Therefore, the size and shape of the parallelogram also change little, and the difference in the winding tilt angle is small. According to another aspect of this application, the size and shape of adjacent x adhesive papers can be set to be the same, that is, each x adhesive papers uses the same winding angle θ, simplifying the work of adjusting the winding angle for each adhesive paper, thereby avoiding the problem of reduced manufacturing efficiency caused by using raw material paper of different specifications. For example, according to the previous formulas (1), (2), (3), (4), the size and winding angle of the 1st, x+1st, 2x+1st, 3x+1st, ... adhesive papers are determined. The first x adhesive papers use the winding angle of the 1st adhesive paper, the next x+1st to 2xth adhesive papers use the corresponding winding angle of the x+1st adhesive paper, and so on, where x is an integer greater than or equal to 2. As an example, every 5 adhesive papers can use the same shape, size, and winding angle.

[0071] According to an embodiment of this application, a dust collector is also provided, which includes the aforementioned dust roller and a handle. The handle includes a handle and a bracket connected to the handle. The bracket is inserted into both ends of the core 200 of the aforementioned dust roller, allowing the dust roller to roll freely on the surface to be cleaned and adsorb dust. The dust roller and the bracket are detachably connected, thereby enabling the dust roller to be replaced.

[0072] According to the adhesive roller of this application, multiple layers of adhesive paper 100 are obliquely wound onto the core 200, one layer on top of the other, which has the advantages of tight winding without unraveling and without contaminating the inner layers of adhesive paper. Furthermore, since the adhesive layer 120 is provided with a separator strip 122, the adhesive roller can roll freely on the surface being cleaned, making it suitable for various surfaces to be cleaned. In addition, since each sheet of adhesive paper 100 has the same width, the same specification of raw material paper can be used, avoiding the use of different specifications of raw material paper during the production of the adhesive roller, resulting in simplified production process, high yield, and high efficiency. Furthermore, it also simplifies the structure and control of the adhesive paper winding equipment.

[0073] Although embodiments of this application have been described in detail with reference to the accompanying drawings, the scope of protection of this application is not limited to the examples described above. Without departing from the spirit and principles of this application, those skilled in the art can make modifications and variations based on these examples, and such modifications and variations will also fall within the scope of protection of this application.
