Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a tool for cleaning and polishing grout materials. Background Technology

[0002] Surface treatment of grouting materials (such as tile grout, epoxy mortar, silicone sealant, etc.) is a crucial process in building decoration, industrial maintenance, and other fields, and its sanding quality directly affects the decorative effect and structural durability. Existing handheld sanding tools generally suffer from the following core defects: traditional sanding tools mostly use hard plastic or wood bases, with flat or right-angled edges on the sanding surface. This rigid structure easily causes excessive local pressure when pressure is applied, leading to excessive wear, dents, or even cracks on the grouting surface; furthermore, most tools use a fixed abrasive design, requiring the use of additional tools and taking a long time to change, and a single abrasive cannot meet the multi-level needs of grouting treatment. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tool for cleaning and polishing grout materials, which has the advantages of convenient operation, good polishing effect and wide applicability.

[0004] The technical solution adopted by this utility model is: a tool for cleaning and polishing grout materials, including a polishing block, a conversion plate, and a polishing assembly; the polishing block includes a supporting part and a flexible part, the end face of the flexible part facing away from the supporting part forms a polishing surface, and the two sides of the polishing surface form an arc-shaped transition area; the conversion plate is attached to the surface of the polishing block and covers the polishing surface and the transition area; the polishing assembly includes a double-hook polishing plate that can be detachably attached to the surface of the conversion plate and an ultra-fine fiber abrasive-free mesh cloth.

[0005] In this technical solution, the grinding block includes a support part and a flexible part. The flexible part disperses the grinding pressure on the grinding surface, making the grinding pressure distribution more uniform. The transition zone forms an arc surface, which makes the transition of the grinding zone edge smoother, ensuring the stability of the grinding block's grinding position movement. The conversion plate, as a medium layer connecting the grinding block and the grinding components, allows for the detachable installation of the double-sided hook grinding disc and the ultra-fine fiber abrasive-free mesh cloth, enabling coarse or fine grinding. This facilitates quick replacement according to different materials and construction needs, and the use of grinding components made of different materials increases the applicability of this grinding structure in the cleaning and grinding operation of grout materials.

[0006] Preferably, the support portion and the flexible portion are fixed together by an adhesive layer.

[0007] Preferably, the support portion is made of high-density EVA foam.

[0008] Preferably, the flexible part is made of soft polyurethane foam.

[0009] Preferably, the conversion sheet is made of single-sided flocked nylon fabric, and the conversion sheet is bonded to the surface of the grinding block by adhesive.

[0010] The beneficial effects of this utility model are as follows: Through the three-dimensional innovation of "flexible mechanical transmission + quick blade replacement + material adaptation", this utility model breaks through the performance bottleneck of traditional hard grinding tools, making grinding more uniform during use, and facilitating quick replacement according to different materials and construction needs. By utilizing grinding components made of different materials, the applicability of this grinding structure in the cleaning and grinding operation of grouting materials is improved, which has high practical value.

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0016] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0017] like Figure 1 and Figure 2As shown in the figure, a specific embodiment of this utility model provides a tool for cleaning and polishing grout materials. This tool is suitable for efficient polishing operations of different grouts. It includes a polishing block 100, a conversion plate 200, and a polishing assembly. The polishing block 100 includes a support portion 110 and a flexible portion 120. The end face of the flexible portion 120 facing away from the support portion 110 forms a polishing surface, and the two sides of the polishing surface form an arc-shaped transition area. The conversion plate 200 is attached to the surface of the polishing block 100 and covers the polishing surface and the transition area. The polishing assembly includes a double-hook polishing disc 300 that can be detachably attached to the surface of the conversion plate 200 and an ultra-fine fiber abrasive-free mesh cloth 400.

[0018] With the above configuration, the grinding block 100 in this embodiment includes a support portion 110 and a flexible portion 120. The flexible portion 120 disperses the grinding pressure on the grinding surface, making the grinding pressure distribution more uniform. The transition zone forms an arc-shaped surface, which makes the transition of the edge of the grinding zone smoother, ensuring the stability of the grinding position movement of the grinding block 100. The conversion plate 200 serves as a medium layer connecting the grinding block 100 and the grinding assembly, allowing the double-sided hook grinding disc 300 and the ultra-fine fiber abrasive-free mesh cloth 400 to be detachably installed, enabling coarse or fine grinding. Both the grinding disc 300 and the microfiber non-abrasive mesh 400 can absorb residues during the grinding process, achieving rapid grinding efficiency. In practical applications, the microfiber non-abrasive mesh 400 can also be used with back-pile injection-molded hooks as a grinding material. It is convenient to replace the grinding disc according to the needs of use. The use of grinding components made of different materials increases the applicability of this grinding structure in the scrubbing and grinding of grouting materials. In particular, it has good grinding effects on barrel-packaged epoxy colored sand, bottle-packaged epoxy colored sand scrubbing process, bottle-packaged polyurea scrubbing process, cement-based grouting, etc.

[0019] In practical applications, the support part 110 uses high-density EVA foam. The flexible part 120 uses soft polyurethane foam, and the support part 110 and the flexible part 120 are fixed together by an adhesive layer. The sanding block 100 adopts a composite structure of "high-density EVA foam support part 110 + soft polyurethane foam flexible part 120", which is connected and fixed by adhesives such as hot melt adhesive. In this way, the support part 110 can provide a rigid base, and the flexible part 120 can disperse the sanding pressure through elastic deformation, thereby reducing the pressure fluctuations acting on the surface of the sealant and avoiding material indentation or damage caused by excessive sanding in certain areas. In addition, the soft polyurethane foam can automatically deform with the contour of the joint, closely conforming to the uneven sealant surface, improving the contact area and sanding efficiency, while reducing the risk of material chipping due to rigid contact.

[0020] The curved transition areas on both sides of the flexible part 120 grinding surface allow for a smooth transition of the contact boundary when the grinding block 100 moves, reducing the width of the edge grinding marks. This is especially suitable for polishing precision joints in ceramic tiles, glass, etc., ensuring a natural transition between the joint and the substrate and improving the overall flatness of the decorative surface.

[0021] The conversion piece 200 is made of single-sided flocked nylon cloth and is bonded to the surface of the polishing block 100 by adhesive. The single-sided flocked nylon cloth is tightly bonded to the flexible part 120 of the polishing block 100 through the adhesive backing layer. At the same time, the surface flocking and the hook-and-loop coupling effect of the double-sided hook polishing piece 300 are utilized to achieve "tear-and-replace" of the polishing components.

[0022] This device is suitable for grouting and sanding in various environments such as kitchens and bathrooms.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model 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 or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
