Description

Technical Field

[0001] This application relates to the field of daily necessities, and in particular to a twill-patterned dust removal roller, a dust removal device, and production equipment. Background Technology

[0002] As people's living standards improve, adhesive paper has become increasingly popular. In the traditional manufacturing process, adhesive paper is typically manufactured by applying glue evenly to paper using a scraping method to form an adhesive layer. This glued paper is then wound onto a core to obtain the adhesive paper roll. However, in production and daily life, people have found that adhesive paper with a uniform adhesive layer often cannot meet certain specific needs.

[0003] For example, to improve the sticky effect, a common approach is to increase the initial tack of the adhesive layer, thereby enabling the adhesion and removal of contaminants (such as dust and hair). However, as the initial tack increases, the difficulty of peeling the sticky paper off the target object also increases, especially on smooth surfaces with high cleanliness. In some cases, the sticky paper may even adhere to the target surface and peel off from the core, or the adhesive layer may peel off from the paper itself. Therefore, this improvement approach presents a dilemma in terms of technological selection, limiting the further development of sticky paper.

[0004] Those skilled in the art continue to attempt to improve the structure of the colloid, for example, by processing the colloid into a three-dimensional structure. However, the corresponding three-dimensional structure of the colloid weakens its adhesion strength to the paper, making it more likely to peel off from the paper in the reverse direction during the bonding and separation process with the target surface. At the same time, the specific structure of the colloid restricts the winding method of the paper roll, places higher demands on manufacturing, affects production costs and efficiency, and limits the design space of such products. Utility Model Content

[0005] To address the aforementioned technical problems, this application discloses a twill-patterned dust removal roller, which has a good adhesion effect on pollutants, a stable adhesive layer structure, can adapt to various target surfaces, and also has high production efficiency and good economic benefits.

[0006] A twill-weave dust collector roller according to this application includes a core and multiple sheets of dust collector paper stacked and spirally wound on the core, each sheet of dust collector paper comprising:

[0007] The base layer includes a release surface and an adhesive surface facing away from each other, wherein the adhesive surface has blank areas on both sides and an adhesive area located between the blank areas;

[0008] The adhesive layer includes a surface adhesive layer disposed in the adhesive area and a linear adhesive layer disposed on the surface adhesive layer. The linear adhesive layer includes multiple adhesive strips, each of which extends in the circumferential direction of the core and is spaced apart in the axial direction of the core.

[0009] The initial tack of the linear adhesive layer is less than that of the surface adhesive layer. When the twill dust removal roller contacts the target surface, the linear adhesive layer contacts the target surface, while the surface adhesive layer maintains a gap with the target surface.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] In one embodiment, the ribbed dust removal roller rolls relative to the target surface in the circumferential direction of the core, and the extension direction of each rubber strip is consistent with the rolling direction.

[0012] In one embodiment, the dust removal paper is a parallelogram in its flattened state and includes a first side and a second side flush with both ends of the core, as well as a third side and a fourth side spirally extending on the core, and each of the adhesive strips extends parallel to the first side and the second side.

[0013] In one embodiment, the angle between each of the adhesive strips and the third and fourth sides is a diagonal angle, and the diagonal angle ranges from 45 degrees to 85 degrees.

[0014] In one embodiment, the blank area includes a first blank area corresponding to the third side and a second blank area corresponding to the fourth side, wherein the dust removal paper partially overlaps the first blank area on the second blank area during the spiral winding process.

[0015] In one embodiment, a receiving groove is formed between each of the adhesive strips, and the surface adhesive layer maintains a gap with the target surface through the receiving groove, the depth of the receiving groove being 0.04 to 0.1 mm.

[0016] In one embodiment, the top adhesive layer is a uniform adhesive layer applied to the adhesive area, the top adhesive layer covers the adhesive area, and each of the adhesive strips is adhered to the top adhesive layer to form the linear adhesive layer.

[0017] In one embodiment, the width of each adhesive strip is 0.2 to 0.6 mm, the height of each adhesive strip is 0.04 to 0.1 mm, and the spacing between each adhesive strip is 1 to 2 mm.

[0018] This application also discloses a dust removal device, including a bracket and a dust removal roller that is rolled on the bracket, wherein the dust removal roller is the twill dust removal roller described in the technical solution of this application.

[0019] This application also discloses a production equipment for a twill-patterned dust collector roller, used to produce the twill-patterned dust collector roller described in the technical solution of this application. The production equipment for the twill-patterned dust collector roller includes:

[0020] The conveying mechanism includes a power unit and conveying rollers driven by the power unit, the conveying rollers conveying the base layer flat.

[0021] The coating mechanism includes a first melting unit and a coating roller. When the substrate passes through the coating roller, the first melting unit delivers a first adhesive and forms the topcoat layer on the bonding surface.

[0022] The transfer mechanism includes a second melting unit and a transfer roller. When the base layer passes through the transfer roller, the second melting unit delivers a second adhesive and forms the linear adhesive layer on the surface adhesive layer.

[0023] The coating mechanism and the transfer mechanism are arranged sequentially in the direction of transporting the base layer.

[0024] The technical solution disclosed in this application overcomes the shortcomings of the prior art by optimizing the structure of the adhesive layer. The linear adhesive layer with relatively low initial tack and the surface adhesive layer with relatively high initial tack constitute a strong-weak adhesive system. The weak adhesive is located on the outside to prevent the strong adhesive from directly contacting the target surface. Under the action of the strong adhesive, the weak adhesive can effectively maintain its position, avoiding damage to the adhesive layer structure or even peeling off from the twill dust removal roller. For users, the twill dust removal roller of this application can adapt to a variety of target surfaces while ensuring good adhesion. For manufacturers, the twill dust removal roller of this application has the advantages of high production efficiency and good economy.

[0025] The specific beneficial technical effects will be further explained in the specific implementation methods in conjunction with the specific structures or steps. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] See appendix Figure 1 In the embodiment shown, this application discloses a twill-patterned dust removal roller, including a core 100 and multiple sheets of dust removal paper 200 stacked and spirally wound on the core 100. Each sheet of dust removal paper 200 is wound on the core 100 to form a complete dust removal surface. The dust removal surface contacts the target surface to adhere to the pollutants on the target surface, thereby achieving the dust removal effect.

[0043] See appendix Figure 2 To be continued Figure 4 In the illustrated embodiment, each dust removal paper 200 includes a base layer 210 and an adhesive layer on the base layer 210. The base layer 210 provides structural support for the processing and use of the dust removal paper 200. In this embodiment, the base layer 210 includes a release surface 211 and an adhesive surface 212 facing away from each other. The release surface 211 is used to abut against the next layer of dust removal paper 200 to reduce the difficulty of removing the dust removal paper 200. The adhesive surface 212 has blank areas on both sides and an adhesive area located between the blank areas. The adhesive layer includes a surface adhesive layer 220 disposed in the adhesive area and a linear adhesive layer 230 disposed on the surface adhesive layer 220. The linear adhesive layer 230 includes multiple adhesive strips 231, each adhesive strip 231 extending circumferentially in the core 100 and spaced apart axially in the core 100. Figure 1 and attached Figure 2 The middle adhesive layer 220 is represented by a shaded area, and the adhesive strip 231 of the line adhesive layer 230 is represented by spaced lines, wherein the attached... Figure 2 The outermost dust-removing paper is peeled off from the twill-weave dust-removing roller. The inner dust-removing paper and the outermost dust-removing paper's adhesive layer 220 are shown with different shades. In this application, the initial tack of the twill-weave dust-removing roller's linear adhesive layer 230 is less than the initial tack of the adhesive layer 220. When the twill-weave dust-removing roller contacts the target surface, the linear adhesive layer 230 contacts the target surface, while the adhesive layer 220 maintains a gap with the target surface.

[0044] The initial tack mentioned above can be measured using the rolling ball method in the national standard GB / T 4852-2002. In one embodiment, the test platform tilts at an angle of 30 degrees, with the initial tack of the linear adhesive layer 230 ranging from a #10 to a #17 steel ball, and the initial tack of the top adhesive layer 220 ranging from a #20 to a #26 steel ball. The difference in initial tack between the linear adhesive layer 230 and the top adhesive layer 220 can be achieved by selecting different adhesives, different adhesive structures, or both methods simultaneously. The combination of different initial tack layers with a three-dimensional adhesive structure allows for adaptability to complex usage scenarios. When the twill dust removal roller contacts the target surface, the lower initial tack of the linear adhesive layer 230 prevents it from bonding too tightly to the target surface. The three-dimensional structure formed by the top adhesive layer 220 with its high initial tack and the spaced adhesive strips 231 effectively achieves stable adhesion to contaminants on the target surface, thus balancing dust removal efficiency and user experience. It boasts advantages such as strong initial tack to contaminants, resistance to tearing, and good adaptability. Each adhesive strip 231, under the influence of the high-tack top adhesive layer 220, effectively maintains its position and preserves the adhesive layer structure, preventing damage or even peeling from the ribbed dust removal roller during use. This allows the adhesive layer to adapt to various target surfaces while ensuring good adhesion. The composite adhesive layer structure also has positive implications for production. During production, different adhesive layers can be applied to the base layer 210 through different processes, reducing the requirements for production equipment and offering advantages such as high production efficiency and good economy.

[0045] For specific settings of the adhesive layer 230, please refer to the appendix. Figure 2 Paper attached Figure 4 In the illustrated embodiment, the ribbed dust removal roller rolls relative to the target surface in the circumferential direction of the core 100, and the extension direction of each adhesive strip 231 is consistent with the rolling direction to avoid the extension direction of the adhesive strip 231 affecting the rolling of the ribbed dust removal roller. The extension direction of the adhesive strip 231 is also related to the boundary of the dust removal paper 200 and the winding method. For example, see attached... Figure 3In the flattened state, the dust removal paper 200 is a parallelogram and includes a first side 201 and a second side 202 flush with both ends of the core 100, and a third side 203 and a fourth side 204 spirally extending on the core 100. In the actual product, each side of the dust removal paper 200 is the same as each side of the base layer 210. Each adhesive strip 231 extends parallel to the first side 201 and the second side 202. The angle between each adhesive strip 231 and the third side 203 and the fourth side 204 is the ribbing angle A1, which ranges from 45 degrees to 85 degrees. In this embodiment, the angle between the first side 201 and the third side 203 and the angle between the second side 202 and the fourth side 204 are equal to the ribbing angle A1. The ribbing angle A1 is preferably 60 degrees to 70 degrees. Adjusting the twill angle can adjust the circumferential extension trend of each adhesive strip 231 on the overall twill dust removal roller, thereby achieving the relative positional relationship mentioned above. For example, it allows the gaps between each adhesive strip 231 to open towards the rolling direction of the dust removal roller, making it easier for contaminants on the target surface to enter the gaps and thus come into contact with the top adhesive layer 220, which has a stronger initial tack. (See attached...) Figure 4 In this structure, receiving grooves 232 are formed between each adhesive strip 231, and the top adhesive layer 220 maintains a gap with the target surface through the receiving grooves 232. The size of the receiving grooves 232 is controlled by the protrusion height of adjacent adhesive strips 231 relative to the top adhesive layer 220 and the relative spacing. In one embodiment, the width of the receiving grooves 232 is 1.5 to 2 mm, and the depth is 0.06 to 0.09 mm.

[0046] For specific settings of the adhesive layer 220, please refer to the appendix. Figure 2 Paper attached Figure 4 In the illustrated embodiment, the adhesive layer 220 is a uniform adhesive layer applied to the adhesive area, covering the adhesive area. The blank areas include a first blank area 213 corresponding to the third side 203 and a second blank area 214 corresponding to the fourth side 204. Accordingly, the adhesive layer 220 has a first boundary 221 and a second boundary 222. The distance between the third side 203 and the first boundary 221 is the width D1 of the first blank area 213, and the distance between the fourth side 204 and the second boundary 222 is the width D2 of the second blank area 214. In different embodiments, the relationship between width D1 and width D2 can be any one of being equal, less than, or greater than. For example, see attached... Figure 3 In the example below, width D1 is smaller than width D2, meaning the first blank area 213 is narrower than the second blank area 214. For another example... Figure 5 In the middle, the first blank area 213 is wider than the second blank area 214, that is, the width D1 is greater than the width D2.

[0047] During the spiral winding process of the dust removal paper 200, the first blank area 213 partially overlaps the second blank area 214, that is, the release surface 211 of the first blank area 213 abuts against the second blank area 214, and the other part of the release surface 211 is bonded to the adhesive layer of the lower dust removal paper 205. Further, the first blank area 213 includes:

[0048] The head 2131 has its lower surface abutting against the upper surface of the second blank area 214;

[0049] The transition section 2132 has its lower surface adhered to the adhesive layer of the lower dust removal paper 205;

[0050] The upper surfaces of the head 2131 and the transition section 2132 are in contact with the release surface 211 of the base layer 210 of the upper dust removal paper 207.

[0051] Combined with appendix Figure 5 As shown, in the radial direction of the core 100, the adjacent dust removal papers 200 from the inside to the outside are the lower dust removal paper 205, the current dust removal paper 206, and the upper dust removal paper 207, respectively; in the circumferential direction of the core 100, the winding starting points of adjacent dust removal papers 200 are staggered. When the upper dust removal paper 207 is peeled off from the current dust removal paper 206, the transition portion 2132 of the first blank area 213 of the current dust removal paper 206 is adhered to the adhesive surface of the lower dust removal paper 205 to remain on the lower dust removal paper 205, and the upper surface of the first blank area 213 of the current dust removal paper 206 is not adhered to the release surface 211 of the upper dust removal paper 207 to achieve separation between the two.

[0052] The head 2131 of the first blank area 213 of each dust removal paper 200 is overlapped on its own second blank area 214 and forms an overlap boundary. When the upper dust removal paper 207 is peeled off from the current dust removal paper 206, a peel line 208 is formed between the release surface 211 of the peeling part and the adhesive layer located on the current dust removal paper 206. The peel line 208 passes through the second boundary 222 of the current dust removal paper 206, the overlap boundary of the current dust removal paper 206 and the first boundary 221 of the current dust removal paper 206 in sequence.

[0053] It is worth noting that, in order to better illustrate the cooperative relationship, an appendix is ​​attached. Figure 4 and appendix Figure 5 The multi-layered structure of the dust removal paper 200 shown in the figure is exaggerated in the height direction, especially the gaps between the dust removal paper 200s. In actual products, the thickness of the dust removal paper 200 itself is less than 1 mm. Considering the flexibility of the dust removal paper 200 and the extensibility of the adhesive layer, the gap size between the dust removal paper 200s can be ignored. For example... Figure 5 In the middle, the first point 2081 and the second point 2082 should be understood as overlapping, that is, the transition part 2132 of the current dust removal paper 206 is completely attached to the adhesive layer of the lower dust removal paper 205.

[0054] Regarding the details of the adhesive layer mating, each adhesive strip 231 is adhered to the surface adhesive layer 220 to form a linear adhesive layer 230. (This is in conjunction with the attached...) Figure 4 In this embodiment, the width W1 of each adhesive strip 231 is 0.2 to 0.6 mm, the height H1 of each adhesive strip 231 is 0.04 to 0.1 mm, and the spacing W2 between each adhesive strip 231 is 1 to 2 mm. Further, the width W1 of each adhesive strip 231 is preferably 0.5 to 0.6 mm, the spacing W2 between each adhesive strip 231 is preferably 1.7 to 1.9 mm, and the height H1 of each adhesive strip 231 is preferably 0.06 to 0.09 mm. The surface adhesive layer 220 and the line adhesive layer 230 are distinguished in observable properties, such as color or texture. In one embodiment, the surface adhesive layer 220 is transparent, and the line adhesive layer 230 is colored.

[0055] Based on the foregoing, this application also discloses a dust removal device, including a support frame and a dust removal roller that is rolled on the support frame. The dust removal roller is the twill-patterned dust removal roller described in this application. The twill-patterned dust removal roller can be implemented in conjunction with the specific description above, and other parts of the dust removal device can be implemented in conjunction with existing technologies.

[0056] Furthermore, in conjunction with the appendix Figure 6 In the illustrated embodiment, this application also discloses a production equipment 900 for producing twill-patterned dust collector rollers, used to produce the twill-patterned dust collector rollers in the technical solution of this application. The production equipment 900 for twill-patterned dust collector rollers includes:

[0057] The conveying mechanism 910 includes a power unit and conveying rollers driven by the power unit. The conveying rollers convey the base layer 210 flat. In the illustrated embodiment, the conveying mechanism 910 is realized by a combination of conveying rollers distributed in each mechanism and conveying rollers located between each mechanism.

[0058] The coating mechanism 920 includes a first melting unit 921 and a coating roller 922. When the base layer 210 passes through the coating roller 922, the first melting unit 921 delivers the first adhesive and forms a top adhesive layer 220 on the bonding surface 212.

[0059] The transfer mechanism 930 includes a second melting unit 931 and a transfer roller 932. When the base layer 210 passes through the transfer roller 932, the second melting unit 931 delivers the second adhesive and forms a line adhesive layer 230 on the surface adhesive layer 220. The transfer roller 932 is provided with a corresponding transfer groove. The second adhesive forms a three-dimensional structure on the surface adhesive layer 220 through the transfer groove. The transfer groove can be tilted relative to the conveying direction of the base layer 210 to adjust the twill angle mentioned above.

[0060] The coating mechanism 920 and the transfer mechanism 930 are arranged sequentially in the conveying direction of the base layer 210.

[0061] The distribution molding of the top adhesive layer 220 and the line adhesive layer 230 reduces production difficulty and improves production efficiency. The top adhesive layer 220 is obtained through a scraping process to improve uniformity, while the line adhesive layer 230 is obtained through a transfer process to avoid affecting the top adhesive layer 220. During the molding process of the line adhesive layer 230, the top adhesive layer 220 adheres to the adhesive on the transfer roller 932, enabling the adhesive strip 231 to be peeled off from the transfer roller 932 and transferred onto the top adhesive layer 220, thus improving transfer efficiency and ensuring transfer quality.

[0062] Furthermore, the production equipment 900 may also include a cooling mechanism 950, a slitting mechanism 940, and a winding mechanism 960. The cooling mechanism 950 can cool the continuous dust removal paper 200 to facilitate subsequent processes. For example, the slitting mechanism 940 cuts the base layer 210 with the line adhesive layer 230 transferred along the blank area to obtain continuous dust removal paper 200. During the slitting process, depending on the slitting position, a first blank area or a second blank area of ​​the same or different size are formed on two adjacent dust removal papers 200. For another example, the continuous dust removal paper 200 can be directly used for the production of twill dust removal rollers or can be wound up. The corresponding winding action can be implemented by the winding mechanism 960.

[0063] Other parts of the production equipment 900 can be implemented using existing technologies, and will not be elaborated here.

[0064] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0065] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
