Description

Technical Field

[0001] This invention relates to the field of tile cleaning technology, and more specifically to a cleaning device for the bonding surface of tiles. Background Technology

[0002] In current building interior decoration projects, ceramic tiles (including slab tiles, antique tiles, and soft-light tiles) are the core material for floor and wall decoration, and grout sealing after tile installation has become an essential procedure. The core function of grout sealing is not only to enhance the aesthetics of the surface, but also to block moisture penetration, prevent mold and blackening in the gaps, and extend the service life of the tile surface. The cleanliness and interface activation effect of the bonding surface on the side of the tile (i.e., the inner wall of adjacent tiles, which is also the core bonding interface between the grout and the tile) are the core prerequisites for determining the bonding strength, waterproof performance, and long-term service stability of the grout. During the tile installation process, it is inevitable that the bonding surface on the side of the tile will have residual hardened tile adhesive, cement-based adhesive lumps, dust, tile release agent, oil stains, and other impurities. If the bonding surface is not thoroughly cleaned to a full depth and without dead corners, it will directly lead to the inability of the grout to form an effective bonding interface with the tile, making it very easy for common quality problems such as grout peeling off, cracking, water seepage, and mold to occur later.

[0003] Referring to the automatic dust removal device for tile grout disclosed in patent number CN111329397A and the tile grout cleaner disclosed in patent number CN106388736A, both can effectively clean tile grout. However, their application is limited to cleaning floor tile grout. When cleaning wall tile grout, it is difficult to accurately align the grout sides, and the high-speed rotation of the "saw-shaped scraper" may damage the tile glaze, while the "dust brush" may not be able to thoroughly clean the grout and sides. Therefore, this application proposes a solution to address these technical shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for the bonding surface of ceramic tiles, which solves the aforementioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solution: a cleaning device for tile bonding surfaces, comprising a frame; The walking module includes a crawler trolley that is slidably mounted in the middle of the frame and is self-driven to reciprocate. The joint cleaning execution component includes a rotary drill rod installed at the bottom of the crawler trolley. The lower end of the rotary drill rod is sequentially fitted with a joint cleaning glue rod and a corner joint grinding head. The joint cleaning glue rod extends to the bottom of the crawler trolley to match the gap of the side wall of the tile mating surface. The outside of the joint cleaning glue rod is equipped with staggered scraping edges. A directional sealing assembly, comprising stacked rings arranged from top to bottom around the outside of the grout cleaning stick and a side enclosure, wherein the side enclosure, the stacked rings, the tile glaze, and the side wall gaps together form an adsorption cavity; A dust hood, which is semi-circular and positioned above and behind the grout cleaning stick in the direction of travel, is used to promptly absorb debris after grout cleaning.

[0006] The further configuration includes: symmetrically rotatably arranged adsorption plates on both sides of the frame, and folding rods slidably installed on the outer sides of both ends of the adsorption plates. The other end of the folding rods is rotatably connected to the outer end of the frame for changing the folding angle of the adsorption plates.

[0007] The following configuration is further provided: an installation hole is provided at one end of the adsorption plate corresponding to the folding rod, the folding rod is slidably connected to the adsorption plate through the installation hole, and a locking bolt is installed at the end of the folding rod corresponding to the adsorption plate.

[0008] The device is further configured such that: an adsorption plate is installed at intervals on the bottom surface of the adsorption plate, and the adsorption plate is connected to the suction end of the vacuum adsorption device.

[0009] The crawler trolley is further configured with a drive structure for driving the seam cleaning execution component in the middle. The drive structure includes a cylinder located in the middle of the crawler trolley. The output end of the cylinder extends through and into the crawler trolley and is connected to a motor. The output end of the motor is equipped with an installation sleeve for connecting the rotary drill rod.

[0010] Further configuration: the bottom of the mounting cylinder is provided with an internal thread that is threaded to the outside of the rotary drill rod; the bottom of the rotary drill rod is provided with a connecting rod that is connected to both ends of the cleaning glue stick; the lower end of the cleaning glue stick is provided with a bottom reamer for inserting the corner grinding head; and the outer side of the lower end of the rotary drill rod near the cleaning glue stick is provided with a glaze edge sleeve that contacts the edge side of the tile bonding surface.

[0011] The further configuration includes: a walking groove for the movement of the crawler trolley is provided in the middle of the frame, and the crawler trolley is equipped with self-driving wheels that are adapted to the walking groove.

[0012] The following configuration is further provided: a grooving scraper is installed on the front side of the crawling trolley corresponding to the direction of travel of the grout cleaning stick; the grout cleaning width of the grooving scraper is the same as the distance between the side walls of the tile bonding surface; and the grooving scraper, the grout cleaning stick, and the dust collection cover are in the same straight line.

[0013] The present invention has the following beneficial effects: This invention addresses the shortcomings of existing technologies, which are unable to thoroughly clean the gaps and sidewalls of tile joints on walls, and suffer from a high probability of glaze damage and incomplete cleaning. Through the coordinated operation of the walking positioning module and the grout cleaning execution component, it achieves fine cleaning and interface activation of the entire depth and surface of the tile joint, thoroughly removing various impurities that affect the adhesion performance of the grout.

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 To address the limitations of existing technologies in thoroughly cleaning the grout lines and sidewalls of wall tiles, as well as the high probability of glaze damage and incomplete cleaning, the following technical solution is proposed: Reference Figure 1 - Figure 9 As shown, this embodiment of a cleaning device for tile bonding surfaces includes a frame 1; a walking module, the walking module including a crawler trolley 3 that is slidably installed in the middle of the frame 1 and self-driven to reciprocate; The joint cleaning execution component includes a rotary drill rod 11 installed at the bottom of the crawler trolley 3. The lower end of the rotary drill rod 11 is sequentially fitted with a joint cleaning glue rod 12 and a corner joint grinding head 17. The joint cleaning glue rod 12 extends to the bottom of the crawler trolley 3 to match the gap of the side wall of the tile joint surface. The outside of the joint cleaning glue rod 12 is equipped with staggered scraping edges 21. The directional sealing component includes a stacked ring 10 and a side enclosure 9, which are stacked from top to bottom and are arranged around the outside of the cleaning adhesive rod 12. The side enclosure 9, the stacked ring 10, the tile glaze and the gaps in the side wall together form an adsorption cavity. The dust hood 13 is a semi-circular ring positioned above and behind the grout cleaning stick 12 in the direction of travel, and is used to promptly absorb debris after grout cleaning.

[0019] The crawler trolley 3 is provided with a drive structure for driving the crack cleaning execution component in the middle. The drive structure includes a cylinder 4 located in the middle of the crawler trolley 3. The output end of the cylinder 4 passes through and extends into the crawler trolley 3 and is connected to a motor 15. The output end of the motor 15 is equipped with an installation sleeve 16 for connecting the rotary drill rod 11. The bottom of the mounting cylinder 16 is provided with an internal thread that is threaded to the outside of the rotary drilling rod 11. The bottom of the rotary drilling rod 11 is provided with a connecting rod 18 that is connected to both ends of the cleaning glue rod 12. The lower end of the cleaning glue rod 12 is provided with a bottom reamer 20 for inserting the corner grinding head 17. The outer side of the lower end of the rotary drilling rod 11 near the cleaning glue rod 12 is provided with a glaze edge sleeve 19 that contacts the edge side of the tile bonding surface. The frame 1 has a walking groove 5 in the middle for the crawler trolley 3 to move, and the crawler trolley 3 is equipped with self-drive walking wheels 8 that are adapted to the walking groove 5.

[0020] The operation process of this embodiment is as follows: Before cleaning the gaps on the side wall of the joint surface of the flat tiles (including the flat tiles on the ground and walls), the frame 1 is first set up stably above the gap of the tile to be cleaned, and the position of the frame 1 is adjusted so that the middle cleaning glue rod 12 is completely aligned with the direction of the gap of the tile to be cleaned, thus completing the initial positioning of the equipment. Reference Figure 5 and Figure 6 As shown, after the operation starts, the piston rod of cylinder 4 extends, driving motor 15 and rotary drill rod 11 connected to it to move downward in the vertical direction. This causes the cleaning glue rod 12, which is coaxially connected to the lower end of the rotary drill rod 11 via connecting rod 18, to be completely embedded in the gap of the tile joint surface until the bottom reamer 20 of the cleaning glue rod 12 is in complete contact with the bottom base surface of the gap. At the same time, the glaze edge sleeve 19 on the outer side of the lower end of the rotary drill rod 11 fits against the glaze edge on both sides of the tile gap, forming a rigid protective isolation for the tile glaze surface, preventing the working parts from having direct contact with the tile glaze surface. Reference Figure 7 and Figure 8 As shown, the motor 15 then starts, driving the rotary drill rod 11 to rotate on a fixed axis via the mounting cylinder 16 at the output end. This, in turn, drives the cleaning adhesive rod 12 and the bottom auger 20 to rotate on the same axis via the connecting rod 18. The scraping edges 21 on the outer wall of the cleaning adhesive rod 12, which are distributed in an alternating pattern, continuously scrape and polish the two side walls of the tile bonding surface with constant force as the rotation occurs. This effectively removes various impurities such as cured tile adhesive, cement-based adhesive lumps, floating dust, tile release agent, and oil stains from the bonding surface. At the same time, the rotating cutting action of the bottom auger 20 thoroughly cleans the cured impurities and deposited dust at the bottom of the gap. This achieves a thorough cleaning and interface activation of the tile bonding surface gap at all depths and on all side walls, providing a clean and highly active bonding interface for subsequent tile grouting. During the cleaning operation, the directional sealing component surrounding the cleaning adhesive rod 12 works synchronously. The stacked rings 10, arranged from top to bottom, adaptively compress and deform with the downward movement of the cylinder 4, so that the bottom edge of the rings fits tightly against the glaze of the tile. Together with the circumferential protection of the side enclosure 9, the rings, the glaze of the tile and the side wall of the gap together form an adsorption cavity, which confines the debris and dust generated during the cleaning operation inside the adsorption cavity, preventing the dust from spreading to the working environment from the source. The semi-circular dust suction hood 13, located above and behind the crevices of the cleaning stick 12 in the direction of travel, is connected to an external negative pressure dust suction device. It continuously suctions out the debris and dust suspended in the crevices and adsorption chamber after cleaning, so as to achieve simultaneous cleaning and dust collection.

[0021] In light of the above, this invention improves upon existing equipment for cleaning the side wall grout lines of tiled surfaces after floor paving, making it suitable for effectively cleaning the side wall grout lines of wall tile joints. Specifically, through the coordinated operation of the walking positioning module and the grout cleaning execution component, it achieves refined cleaning and interface activation of the entire depth and surface of the tile joint, thoroughly removing various impurities that affect the adhesion performance of the grout. Furthermore, the accompanying glaze protection structure isolates the working components throughout the process, effectively preventing scratches and chipping of the tile glaze, fundamentally improving the interface adhesion strength of the subsequent grout.

[0022] Example 2 Reference Figure 1 - Figure 9 As shown, this embodiment, in conjunction with Embodiment 1, improves the cleaning of the gaps at the external corners of tiles that cannot be handled during the cleaning process of tile bonding surfaces. It includes: symmetrically rotating adsorption plates 2 are provided on both sides of the frame 1. Folding rods 7 are slidably installed on the outer sides of both ends of the adsorption plates 2. The other end of the folding rods 7 is rotatably connected to the outer end of the frame 1 for changing the folding angle of the adsorption plates 2. The adsorption plates 2 have a mounting hole 22 at one end corresponding to the folding rods 7. The folding rods 7 are slidably connected to the adsorption plates 2 through the mounting hole 22. A locking bolt 23 is installed at the end of the folding rods 7 corresponding to the adsorption plates 2. Reference Figure 9 As shown, when cleaning the joint gap at the corner of a tile, first release the locking bolt 23 at the end of the folding rod 7, allowing the folding rod 7 to slide and extend freely along the mounting hole 22 at the end of the adsorption plate 2. At the same time, pull the adsorption plate 2 to rotate around its rotation connection point with the frame 1. Adjust the rotation angle of the adsorption plates 2 on both sides of the frame 1 according to the included angle between the two sides of the corner of the tile to be cleaned, so that the surfaces of the two adsorption plates 2 are fully in contact with the glazed surfaces of the tiles on both sides of the corner. After adjustment, tighten the locking bolt 23 to lock the relative position of the folding rod 7 and the adsorption plate 2, thereby achieving precise pre-positioning of the frame 1 at the corner of the tile, adapting to the positioning needs of various irregular corner scenarios such as 90° vertical corners and obtuse corners.

[0023] Reference Figure 1 and Figure 2 As shown, adsorption plates 6 are installed at intervals on the bottom surface of the adsorption plate 2. The adsorption plates 6 are connected to the suction end of the vacuum adsorption device. Furthermore, the vacuum adsorption device connected to the adsorption plates 6 installed at intervals on the bottom surface of the adsorption plate 2 is activated. Through the negative pressure suction, the adsorption plates 6 are firmly adsorbed and fixed to the glaze of the tile, thereby stabilizing the entire cleaning equipment on the tile surface at the corner. No manual hand support is required during the corner cleaning process, which can achieve self-fixation of the equipment and completely solve the problem of difficult equipment positioning and easy displacement during corner cleaning.

[0024] Reference Figure 6 As shown, a grooving scraper 14 is installed on the front side of the crawling trolley 3 corresponding to the direction of travel of the grout cleaning stick 12. The grout cleaning width of the grooving scraper 14 is the same as the distance between the side walls of the tile joint surface. The grooving scraper 14, the grout cleaning stick 12 and the dust collection cover 13 are in the same straight line. While the cleaning adhesive rod 12 rotates, the crawler trolley 3, through the meshing transmission between its self-drive wheels 8 and the travel groove 5 in the middle of the frame 1, moves in a uniform linear motion along the extension direction of the travel groove 5, thereby driving the entire cleaning execution component to move synchronously along the direction of the tile gap. The grooving blade 14 on the front side of the crawler trolley 3 moves synchronously with the crawler trolley 3, pre-cutting, breaking, and grooving the large solidified lumps in the gap, loosening and peeling off the lumps, reducing the workload for the subsequent fine grinding and cleaning of the cleaning adhesive rod 12. At the same time, the cleaning width of the grooving blade 14 is consistent with the distance between the side walls of the tile mating surface, which can be used to calibrate the direction of the gap in real time, avoiding swaying during the movement of the cleaning adhesive rod 12, and ensuring the straightness and cleaning accuracy of the cleaning operation.

[0025] Reference Figure 7 and Figure 8 As shown, during the cleaning of external corner gaps, according to the specifications of the external corner gaps and the cleaning requirements, a suitable external corner grinding head 17 can be inserted into the bottom auger 20 at the lower end of the cleaning stick 12. The external corner grinding head 17 is driven to rotate synchronously by the fixed axis rotation of the rotary drill rod 11, and the side wall of the tile bonding surface of the external corner is finely ground and cleaned. At the same time, the crawler trolley 3 moves back and forth at a uniform speed along the direction of the external corner gap to achieve continuous cleaning of the entire length of the external corner gap. During the operation, the glaze edge sleeve 19 at the end of the rotary drill rod 11 always fits against the edge of the ceramic tile glaze on both sides of the external corner, forming an all-round protective isolation, effectively preventing the external corner grinding head 17 and the joint cleaning glue stick 12 from causing scratches, chipping, or bumps to the ceramic tile external corner glaze during the rotary grinding process, thus ensuring the integrity and aesthetics of the ceramic tile surface.

[0026] The beneficial effects are as follows: the entire cleaning equipment can be applied to the grout lines of tiles, and the pre-grooving structure can break up solidified lumps, reduce the workload, and ensure the straightness of the cleaning, meeting the stable positioning requirements of the corner work; the directional closed dust collection module can control and collect the dust at the source of the cleaning, prevent the spread of dust during operation, and optimize the construction environment; the angle-adjustable adsorption and fixing module can achieve stable self-fixation of the equipment in multiple scenarios such as walls and corners, without the need for continuous manual support, significantly reducing the intensity of work and broadening the applicable scenarios of the equipment.

[0027] In summary, this invention, combining Embodiment 1 and Embodiment 2, achieves, on the one hand, meticulous cleaning and surface activation of the tile bonding surface through the coordinated operation of the walking positioning module and the grout cleaning execution component, thoroughly removing various impurities that affect the adhesion performance of the grout; on the other hand, it achieves source control and real-time collection of grout cleaning dust through the directional closed dust collection module, preventing the spread of dust during operation and optimizing the construction environment; the angle-adjustable adsorption and fixing module enables the equipment to be stably self-fixed in various scenarios such as walls and corners, eliminating the need for continuous manual support, significantly reducing work intensity, and broadening the applicable scenarios of the equipment.

[0028] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
