Description

Technical Field

[0001] The present application relates to the field of dust-removing daily necessities, in particular to a dust-removing paper roll with spaced adhesive strips, a dust remover, and a processing device for the dust-removing paper roll. Background Art

[0002] With the improvement of people's living standards, dust-removing paper has gradually become popular. In the traditional manufacturing process of dust-removing paper, glue is usually evenly applied to the paper by a scraping method, and then the paper coated with glue is wound around a core to obtain a dust-removing paper roll. However, people have found in production and life that dust-removing paper with a uniform glue layer often cannot meet certain specific requirements.

[0003] For example, in order to improve the dust-removing effect, a common improvement route is to increase the bonding strength of the colloid, so as to achieve the adhesion and removal of external particles (such as dust and hair); however, as the bonding strength increases, the difficulty of peeling the dust-removing paper from the target object also increases synchronously. Especially on a smooth surface with a high degree of cleanliness, the dust-removing paper may even peel off from the core instead. Therefore, there is a dilemma in technical selection in this improvement route, which restricts the further development of dust-removing paper.

[0004] Those skilled in the art continue to try to improve the structure of the colloid, such as processing the colloid into a three-dimensional structure. However, similarly, a glue layer with a specific structure poses higher requirements for production and manufacturing, affecting production cost and production efficiency.

[0045] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0046] Refer to the appended Figure 1 to the appended Figure 6 , this application discloses a dust sticking paper roll of a spacer strip, which includes a core 1 and multiple layers of dust sticking paper 2 spirally wound around the core 1. The multiple layers of dust sticking paper 2 are stacked in the radial direction of the core, and each layer of dust sticking paper 2 is independently spirally wound around the core 1. Each layer of dust sticking paper 2 includes:

[0047] a base layer 21, including a release surface 211 and an adhesive surface 212 facing away from each other;

[0048] an adhesive layer 22, including multiple adhesive strips 221 arranged at intervals on the adhesive surface 212. Each adhesive strip 221 bulges relative to the adhesive surface 212, and the gap between adjacent adhesive strips 221 is an open accommodation groove 222, and the adhesive surface 212 is exposed to the outside through the accommodation groove 222.

[0049] The adhesive strips 221 arranged at intervals can reduce the contact area when the dust sticking paper roll contacts the target object, thereby avoiding the situation where the dust sticking paper roll and the dust sticking paper 2 are difficult to peel off from the target object. The problem of reduced adhesive force caused by the reduction of the contact area can be overcome by improving the adhesive strength of the colloid and by the accommodation groove 222 that can accommodate external particles. Further, in this application, the structure of the adhesive layer 22 is optimized, avoiding the technical problems of high requirements for production processes and equipment in the prior art. Therefore, generally speaking, the dust sticking paper roll of this application can significantly improve the dust sticking ability and optimize the peeling effect while reducing the requirements for production, comprehensively improving the user experience and having broad market application prospects.

[0050] In the specific setting of the adhesive layer 22, refer to the appended Figure 2 to the appended Figure 3In the illustrated embodiment, each adhesive strip 221 includes a main adhesive surface 2211 facing away from the bonding surface 212 and side adhesive surfaces 2212 located on both sides of the main adhesive surface 2211. The side adhesive surfaces 2212 between adjacent adhesive strips 221 form the side walls of the accommodating groove 222, and the side adhesive surfaces 2212 between adjacent adhesive strips 221 are used to hold external particles in the accommodating groove 222. The side adhesive surfaces 2212 are located within the accommodating groove 222 and do not directly contact the target object, which can reduce the difficulty of peeling the dust sticking paper roll and the dust sticking paper 2 from the target object while ensuring the overall area of the bonding surface 212. At the same time, the accommodating groove 222 is exposed to the outside, and external particles are stuck between the adhesive strips 221 on the dust sticking paper 2 and held in the accommodating groove 222, making it not easy to fall off, thereby improving the use effect of the dust sticking paper 2. Specifically, when the dust sticking paper 2 is in a flattened state, the ratio of the bonding area of the adhesive layer 22 with the target object to the area of the bonding surface 212 is 0.3 to 0.8. In Figure 1 it, when the dust sticking paper 2 is in a flattened state, the ratio of the bonding area of the adhesive layer 22 with the target object to the area of the bonding surface 212 is 0.5. In different products, this ratio can be adjusted plus or minus 20%.

[0051] Regarding the specific setting of the accommodating groove 222, referring to the attached Figure 3 description, the height and width of each adhesive strip 221 are uniformly set, and the depth of the accommodating groove 222 is close to the height of the adhesive strip 221, for example, with a difference of plus or minus 30%. Similarly, the opening width of the accommodating groove 222 is close to the width of the adhesive strip 221, for example, with a difference of plus or minus 30%. The width of the adhesive strip 221 is 0.1 to 0.5 mm, the height of the adhesive strip 221 is 4 to 15 μm, and the spacing between adjacent adhesive strips 221 is 0.5 to 1.5 mm. In Figure 3 it, the width W1 of the adhesive strip 221 is 0.4 mm, the height H1 of the adhesive strip 221 is 7 μm, and the spacing D1 between adjacent adhesive strips 221 is 1 mm. These dimensions can be adjusted plus or minus 30% in different products. Under the above parameters, compared with the existing coating method, the three-dimensional adhesive layer structure on the dust sticking paper 2 in this embodiment can improve the effect of adding a 6# steel ball in the adhesion test on the premise of the same amount of glue applied per square meter. Among them Figures 2 to 4 To better display the spatial structure of the adhesive strip 221, the height of the adhesive strip 221 in the figure is exaggeratedly represented. It can be understood that in other embodiments, the height or width of the adhesive strip 221 can also be set differently from other adhesive strips 221. For example, the height or width of one of the adhesive strips 221 is set differently from other adhesive strips 221; or for another example, the spacing between one of the adhesive strips 221 and adjacent adhesive strips 221 is set differently from other adhesive strips 221.

[0052] Regarding the microscopic structure of the adhesive strip 221, referring to the attached Figure 4In the illustrated embodiment, in cross-section, each adhesive strip 221 includes a shaping layer 2213 located on the outer layer and an adhesive core 2214 located on the inner side. The shaping layer 2213 is stressed to change the shape of the adhesive strip 221 and maintain that shape. The main adhesive surface 2211 and the side adhesive surface 2212 are located on the shaping layer 2213. In the figure, the shaping layer 2213 and the adhesive core 2214 can be made of the same component of glue. In other embodiments, the shaping layer 2213 and the adhesive core 2214 can be made of glues with different components to achieve different physical and chemical properties. For example, the shaping layer 2213 has better adhesiveness and shaping properties, and the adhesive core 2214 has better structural strength to maintain the overall cross-sectional shape of the adhesive strip 221.

[0053] Regardless of the structure of the adhesive strip 221, the main adhesive surface 2211 and the side adhesive surface 2212 of the adhesive strip 221 in this application are both regularized surfaces to ensure the overall structure of the adhesive layer 22, that is, the surface morphology of the main adhesive surface 2211 and the side adhesive surface 2212 is processed into a preset morphology. For example, a preset shape is formed by die extrusion.

[0054] This application does not limit the extension direction of the adhesive strip 221. For example, Figure 1 In the illustrated embodiment, each adhesive strip 221 extends in the second direction 32, and the second direction 32 points to the axial direction of the core 1. "Points to" represents a general direction. For example, the second direction 32 can be set parallel to the axial direction of the core 1, or the second direction 32 can be set to intersect the axial direction of the core 1 and the included angle between the two is less than 60 degrees.

[0055] For another example, Figure 6 In the illustrated embodiment, each adhesive strip 221 extends in the second direction 32, and the second direction 32 points to the circumferential direction of the core 1. Similarly, "points to" here also represents a general direction. For example, the second direction 32 can be set parallel to the circumferential direction of the core 1, or the second direction 32 can be set to intersect the circumferential direction of the core 1 and the included angle between the two is less than 60 degrees.

[0056] The dust sticking paper is spirally wound around the core 1 in the first direction 31, and the first direction 31 intersects the circumferential direction of the core 1 to achieve the spiral winding of the dust sticking paper on the core 1. In a single roll of dust sticking paper, the dust sticking paper includes a first side edge close to the end of the core 1 and a second side edge spirally extending on the core. In Figure 1 In the illustrated embodiment, the adhesive strip intersects the first side edge and the second side edge. In Figure 6 In the illustrated embodiment, the adhesive strip can be set parallel to the first side edge and intersect the second side edge. Further, the included angle between the adhesive strip and the second side edge ranges from 15 degrees to 45 degrees.

[0057] That is, Figure 1 and Figure 6The sticky dust paper roll shown is designed for diagonal tearing. When making a product with diagonal tearing, it is easier for consumers to find the joint during use, which improves the user experience. Further, the sticky dust paper 2 is spirally wound around the core 1, and the adhesive strips 221 between adjacent spirals are arranged in alignment with each other. In other embodiments, the adhesive strips 221 between adjacent spirals are arranged in a staggered manner. Further, in the diagonal tearing product, the adhesive strip 221 is inclined with respect to one side of the sticky dust paper 2, and the included angle between the two is in the range of 45 degrees to 75 degrees.

[0058] In the present application, the adhesive layer 22 can achieve the sticky dust effect by relying on the three-dimensional structure formed by the adhesive strips 221. Therefore, in the attached Figure 2 to the attached Figure 4 In the illustrated embodiment, the bonding surface 212 is a non-sticky surface, that is, the base layer 21 is a separate fabric processed according to the bonding and release requirements on both sides, such as a polymer base material, a paper base material, or a fabric base material. In other embodiments for special working conditions, the bonding surface 212 can also be further optimized, for example, as attached Figure 5 shown, the bonding surface 212 is a sticky glue surface, and the glue surface is a bonding layer 2121 that is part of the bonding surface 212 in the figure. The bonding layer 2121 can cooperate with the adhesive strips 221 to further form a three-dimensional structure. In this solution, the inner walls of the accommodation grooves 222 are all sticky.

[0059] The above-mentioned adhesive layer 22 structure can be obtained through multiple processes using the existing scraping method, or can be obtained by the transfer coating method. Therefore, the present application also discloses a glue layer transfer printing process, including

[0060] Scraping glue onto the transfer roller, and the surface of the transfer roller is at least provided with a plurality of glue-containing grooves for forming the adhesive strips 221 and a fitting portion that fits onto the base layer 21.

[0061] By rotating the transfer roller, the glue is transferred from the transfer roller to the base layer 21, and the glue located in the grooves forms the adhesive strips 221 that bulge on the base layer 21. The fitting portion drives the glue to form the accommodation grooves 222 between the adhesive strips 221. Each adhesive strip 221 and the accommodation groove 222 form an adhesive layer 22 with a preset thickness and structure on the base layer 21. In terms of process parameters, the width of the glue-containing groove is 0.2 to 1.8 millimeters, the depth of the glue-containing groove is 5 to 35 micrometers, and the distance between each glue-containing groove is 0.5 to 1.5 millimeters.

[0062] Referring to the attached Figure 7 In the illustrated embodiment, the present application also discloses processing equipment for the sticky dust paper roll, including:

[0063] A unwinding device 41 for unwinding the rolled base layer 21. The base layer 21 can be extended in length and width as required to improve the production efficiency of transfer printing. After transferring the adhesive layer 22, it can be cut into a preset size through a slitting device 45 and a winding device.

[0064] The conveying device 42 is used to convey the base layer 21, and the base layer 21 includes a release surface 211 and an adhesive surface 212 facing away from each other. The conveying device 42 includes a plurality of conveying rollers to convey the continuous base layer 21, and the adhesive surface 212 of the base layer 21 faces the transfer device 43. The conveying device 42 can also be used to convey the base layer 21 after the transfer adhesive layer 22.

[0065] The transfer device 43 includes a roller for transferring the adhesive layer 22 to the adhesive surface 212. Glue receiving grooves are arranged at intervals on the roller, and the fitting portions fitting to the base layer 21 are between the glue receiving grooves. The roller and the base layer 21 are mutually extruded to form the adhesive layer 22 on the base layer 21. The adhesive layer 22 includes a plurality of mutually spaced glue strips 221 and open accommodation grooves 222 between the glue strips 221. The transfer device 43 further includes a glue coating assembly 44 for coating the roller with glue. The glue coating assembly 44 can evenly coat the roller with glue, or can coat the glue receiving grooves through independent glue nozzles. Further, the glue coating assembly 44 can also be provided with a scraper to distribute the glue, and the scraper can only act on the fitting portion of the roller, or can extend into the glue receiving grooves.

[0066] The slitting device 45 is used to slit the base layer 21 with the transferred adhesive layer 22 into a preset width to obtain the continuous dust sticking paper 2. The slit dust sticking paper 2 can be separately rewound for subsequent use, or can be directly conveyed to the winding device for continuous production.

[0067] The winding device is used to wind the slit dust sticking paper around the core; the winding device can use a twill rewinder to wind multiple dust sticking paper rolls around the core in sequence to complete rewinding.

[0068] The roll splitting device is used to axially cut the core wound with the dust sticking paper according to a preset size to obtain the dust sticking paper roll.

[0069] Through the above description, it is not difficult to understand that the present application also discloses a dust collector, including a bracket (not shown in the figure) and a dust sticking paper roll installed on the bracket. The dust sticking paper roll is the dust sticking paper roll with spaced glue strips in the above technical solution.

[0070] The technical features of the above-described embodiments can be arbitrarily combined. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combined examples of the respective embodiments involved.

[0071] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
