Description

Technical Field

[0001] This invention relates to the field of roll flooring sanding technology, specifically to a roll flooring surface treatment and sanding robot. Background Technology

[0002] Roll flooring is a type of floor covering material made primarily of polymer materials through a specific process. It features continuous installation, a seamless finish, high installation efficiency, and wide applicability, making it widely used in commercial spaces, industrial plants, public areas, and residential homes. Surface sanding is a crucial step in the production of roll flooring, its core purpose being to optimize the surface quality of the flooring, ensuring the smooth progress of subsequent processes and that the final product meets performance standards.

[0003] In existing technologies, surface treatment and sanding robots for roll flooring have replaced traditional manual sanding, achieving continuous, precise, and efficient sanding of roll flooring surfaces. When sanding roll flooring, the robot primarily relies on the sharp tips of the abrasive particles on the sanding belt to cut and remove defects from the surface. However, after prolonged sanding, the abrasive tips on the sanding belt wear down and become rounded, resulting in dulling. This significantly reduces the cutting force, affecting the sanding effect and lowering the pass rate of roll flooring surface treatment.

[0004] Therefore, we propose a surface treatment and sanding robot for roll flooring to address the problems mentioned in the background section. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In use, the cylinder drives the repair roller, composed of modular repair components, to move and contact the abrasive belt. As the abrasive belt rotates, the repair roller rotates synchronously and passively. The fine silicon carbide abrasive material on the surface of the silicon carbide abrasive layer performs micro-cutting on the passivated abrasive on the surface of the abrasive belt, reshaping the sharp cutting surface of the abrasive. The elastic rubber core has flexible self-adaptive capabilities, ensuring full-width contact between the repair roller and the abrasive belt, thus better repairing the abrasive belt's polishing effect.

[0020] 2. In use, the limiting threaded rod is rotated into the threaded hole, simultaneously causing the T-shaped threaded rod to rotate and move forward, pulling the concave block and the double-rod movable part forward, while simultaneously moving the reinforcing rod out of the connecting block. Repeat the above process to remove the reinforcing rod from the corresponding connecting block in another switching mechanism. Pull out the two connecting rings, separating the two elastic rubber cores and the two tightly contacting silicon carbide abrasive layers, while simultaneously pulling the connecting block out of the connecting groove, thus removing the modular repair component. Under the action of the switching mechanism, the modular repair component can be quickly disassembled and assembled, or the positions of different types of modular repair components can be changed to strengthen and repair different parts of the abrasive belt.

[0021] 3. When using this invention, the conveying system transports the roll flooring, which passes through the grinding roller and two grinding belts. The grinding roller performs initial grinding on the surface of the roll flooring, quickly removing large defects in the coarse grinding stage. The two grinding belts achieve medium and fine grinding in stages, greatly improving the grinding effect. The grinding machine mechanism achieves three-stage gradient grinding, improving the grinding accuracy.

[0022] 4.

The abrasive mesh count on the surface of the silicon carbide abrasive layer of the local reinforcement modular repair component is higher than that of the basic repair type. The local reinforcement modular repair component can be used to locally reinforce and repair the grinding belt, while the basic repair modular repair component can be used to repair other locations normally, which is beneficial to improving the overall repair effect.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-13As shown, the present invention provides a technical solution: a roll floor surface treatment and sanding robot, including a sanding machine mechanism 1, a repair mechanism 2 for repairing the surface of the sanding belt is set inside the sanding machine mechanism 1, and a replacement mechanism 3 is set inside the repair mechanism 2; the repair mechanism 2 includes a fixed plate 201, a cylinder 203 is fixedly installed at the center of one outer surface of the fixed plate 201, a repair seat 205 is fixedly installed at the output end of the cylinder 203, a limit shaft 206 is fixedly installed inside the repair seat 205, a rotating cylinder 210 is movably sleeved on the outer surface of the limit shaft 206, and a modular repair component 21 is movably sleeved on the outer surface of the rotating cylinder 210;Modular repair component 21 includes two connecting rings 2101, each with an elastic rubber core 2102 fixedly connected to its outer surface. A silicon carbide abrasive layer 2103 is fixedly connected to the outer surface of each elastic rubber core 2102. The connecting rings 2101 facilitate the replacement and assembly of the modular repair component 21. The elastic rubber cores 2102 ensure better contact between the silicon carbide abrasive layer 2103 and the grinding belt. The silicon carbide abrasive layer 2103 is used to perform micro-cutting on the passivated abrasive on the surface of the grinding belt, repairing it into sharp abrasive. A laser rangefinder sensor 204 is fixedly installed on one side of the outer surface of the fixing plate 201. Repair mechanism 2 There are two repair mechanisms 2, each located on one side of the outer surface of the two sanding belts 111. The modular repair components 21 are configured in two types: basic repair and localized reinforcement repair. Multiple modular repair components 21 are provided. Three fixing brackets 202 are fixedly installed on the other side of the fixing plate 201. The tops of the three fixing brackets 202 are all fixedly installed on the top surface inside the sanding machine housing 101. Slide rails 208 are fixedly installed on the front and rear surfaces of one side of the fixing plate 201. Slider blocks 209 are movably fitted onto the outer surfaces of both slide rails 208. The outer surfaces of the two sliders 209 are respectively fixed on one side of their respective outer surfaces. Installed on the front and rear surfaces of the repair base 205, the two elastic rubber cores 2102 are tightly fitted on opposite sides, the two silicon carbide abrasive layers 2103 are tightly fitted on opposite sides, and the inner walls of the two connecting rings 2101 are in contact with the outer surface of the rotating cylinder 210. The grinding machine mechanism 1 includes a grinding machine housing 101, a PLC control system 102 is installed on one outer surface of the grinding machine housing 101, a conveying system 103 is installed inside the grinding machine housing 101, and two bases 105 are fixedly installed on both sides inside the grinding machine housing 101. A first drive system 106 is installed on one side of the top of the two bases 105. The grinding machine housing 101 has a grinding roller 107 inside. Two second drive systems 108 are mounted on the top of the two bases 105. Each of the two second drive systems 108 has a drive roller 109 inside. Each of the two second drive systems 108 has a tensioning system 110 on its top. A grinding belt 111 is movably fitted onto the outer surface of each tensioning system 110. The interior of each grinding belt 111 contacts the bottom of the two drive rollers 109. Limiting strips 112 are fixedly installed on both sides of the front and rear surfaces of the two second drive systems 108 and the two tensioning systems 110. A dust extraction system 104 is installed on the rear wall inside the grinding machine housing 101.

[0040] In this embodiment, multiple modular repair components 21 are provided during use and are assembled and installed on the outer surface of the rotating cylinder 210 through the switching mechanism 3 to form an integral repair roller. Two repair mechanisms 2 are provided, located on one side of the two abrasive belts 111, i.e., on the return path of the abrasive belts 111. The abrasive belts 111 are fitted onto the outer surfaces of the tensioning system 110 and the drive roller 109. Under the action of the limiting strip 112, the abrasive belts 111 are limited and placed in the center. Then, the tensioning system 110 is activated to tension the abrasive belts 111, as shown below. Figure 3 As shown. Next, cylinder 203 and laser rangefinder 204 are activated. Cylinder 203 pushes the repair seat 205 to move. At the same time, through the cooperation of limit shaft 206 and rotating cylinder 210, the integral repair roller composed of multiple modular repair components 21 is pushed to move towards the abrasive belt 111. Meanwhile, laser rangefinder 204 measures the distance change between itself and the repair seat 205 and transmits the detected distance data to PLC control system 102 for identification and comparison via electrical signals. When the moving distance of the repair seat 205 matches the set value, PLC control system 102 controls cylinder 203 to close, so that the silicon carbide abrasive layer 2103 of the two repair rollers respectively adheres to the outer surface of the two abrasive belts 111. During the sanding process, the roll flooring is conveyed to the sanding machine housing 101 via the conveyor system 103. After the sanding belt 111 sands the surface of the roll flooring, it continues to rotate and comes into contact with the repair roller. The repair roller rotates passively in sync with the sanding belt 111 and, under the connection of the switching mechanism 3, drives the rotating cylinder 210 to rotate on the outer surface of the limiting shaft 206. The fine silicon carbide abrasive material on the surface of the silicon carbide abrasive layer 2103 on the outside of the repair roller performs micro-cutting on the passivated abrasive on the surface of the sanding belt 111, re-cutting the arc-shaped tip of the abrasive into a sharp shape and reshaping the sharp cutting surface of the abrasive. At the same time, the pressure of the repair roller can generate a "reverse support force" on the fallen abrasive. Combined with the slight force on the root of the abrasive during the micro-cutting process, the tilted abrasive is made to stand upright again, ensuring that the abrasive can "vertically cut" the surface of the roll flooring during subsequent sanding and avoiding poor sanding due to falling over. The elastic rubber core 2102 has flexible self-adaptive capabilities, which can adapt to the slight undulations on the surface of the abrasive belt 111, ensuring full-width contact between the repair roller and the abrasive belt 111, and better repairing the abrasive effect of the abrasive belt 111. During the abrasive repair process on the surface of the roll flooring, the dust extraction system 104 sucks up dust particles and discharges them centrally through the external dust collection pipe. Under the action of the repair mechanism 2, the abrasive on the surface of the abrasive belt can be repaired, improving its abrasive effect. This solves the problem that after long-term operation, the abrasive tips on the surface of the abrasive belt in the roll flooring surface treatment abrasive robot will wear and become rounded, greatly reducing the cutting force, which in turn affects the abrasive treatment effect of the abrasive belt and reduces the pass rate of roll flooring surface treatment.

[0041] Furthermore, the modular repair component 21 is configured in two types: basic repair type and localized enhanced repair type, such as... Figure 6 As shown, the abrasive mesh count of the silicon carbide abrasive layer 2103 surface in the basic repair modular repair component 21 is higher than that on the surface of the sanding belt 111. In the local reinforcement modular repair component 21, the abrasive mesh count of the silicon carbide abrasive layer 2103 surface is higher than that of the basic repair type. On the rotating cylinder 210, the two sides are local reinforcement modular repair components 21, and the middle is the basic repair modular repair component 21. The edges of the sanding belt 111 come into contact with the edges of the roll flooring during sanding, experiencing greater friction and wear. The local reinforcement modular repair components 21 on both sides can reinforce and repair the edges of the sanding belt 111, while the middle of the sanding belt 111 is repaired normally using the basic repair modular repair component 21, which helps improve the overall repair effect.

[0042] Example 2: Figures 7-13As shown, the grinding machine mechanism 1 is internally equipped with a repair mechanism 2 for repairing the surface of the grinding belt. The repair mechanism 2 is internally equipped with a replacement mechanism 3. The replacement mechanism 3 includes a fixing strip 301. Multiple connecting grooves 302 are formed on both outer surfaces of the fixing strip 301. Multiple movable grooves 303 are formed inside the fixing strip 301. Reinforcing blocks 304 are movably embedded inside each of the movable grooves 303. Two reinforcing rods 305 are fixedly installed on one outer surface of each reinforcing block 304. A double-rod movable component 306 is fixedly installed inside the reinforcing block 304. A concave block 307 is fixedly installed on one outer surface of the double-rod movable component 306. A T-shaped threaded rod 308 is movably embedded inside the concave block 307. A limit threaded rod 309 is fixedly installed at one end of the T-shaped threaded rod 308. Two locking pins 2104 are fixedly installed on the inner walls of the two connecting rings 2101. Four connecting blocks 2105 are fixedly installed on the opposite side of the two connecting rings 2101. Two openings are provided on the front surface of the repair seat 205. A threaded hole 207; multiple position marking strips 211 are equidistantly arranged on the outer surface of the rotating cylinder 210; multiple slots 212 are opened on the outer surface of the rotating cylinder 210; the outer surface of the fixing strip 301 is fixedly installed on the outer surface of the rotating cylinder 210; one end of multiple reinforcing rods 305 respectively movably passes through the interior of multiple connecting slots 302; the outer surface of multiple connecting blocks 2105 is movably embedded in the interior of multiple connecting slots 302; one end of multiple reinforcing rods 305 respectively movably passes through the interior of multiple connecting blocks 2105; multiple moving holes 310 are opened inside the fixing strip 301; the outer surface of multiple double rod movable parts 306 is movably embedded in the interior of multiple moving holes 310 and multiple moving slots 303; one end of the T-shaped threaded rod 308 is threaded through one of the moving slots 303 to the front surface of the fixing strip 301; four changing mechanisms 3 are provided, and the four changing mechanisms 3 are respectively installed on the outer surfaces of two rotating cylinders 210; the opposite side of the connecting ring 2101 is in contact with the outer surfaces of both sides of the fixing strip 301.

[0043] In this embodiment, during use, multiple position marking strips 211 are provided on the outer surface of the rotating cylinder 210 to facilitate the precise installation of the modular repair assembly 21. The modular repair assembly 21 is rotated so that the two limiting threaded rods 309 are aligned with the two threaded holes 207. Then, one hand temporarily fixes the modular repair assembly 21, while the other hand rotates the screw block at the connection between the limiting threaded rod 309 and the T-shaped threaded rod 308, causing the limiting threaded rod 309 to move towards the threaded hole 207. Simultaneously, the T-shaped threaded rod 308 rotates and moves forward inside the concave block 307. The movement of the T-shaped threaded rod 308 pulls the concave block 307 outward, thereby causing the double-rod movable part 306 to move forward. Simultaneously, multiple reinforcing rods 305 are moved out of the connecting block 2105. At this point, multiple modular repair assemblies 21 are fitted onto the outer surface of the rotating cylinder 210 through the cooperation of the locking post 2104 and the locking groove 212. At this time, one end of the limiting threaded rod 309 gradually enters the corresponding threaded hole 207. The limiting threaded rod 309 is then threadedly connected to the repair seat 205, and the T-shaped threaded rod 308 is threadedly connected to the fixing strip 301, fixing the position of the fixing strip 301 and thus fixing the rotating cylinder 210 to prevent it from rotating. Repeating the above process, the reinforcing rod 305 in the other replacement mechanism 3 is removed from the corresponding connecting block 2105. Pulling out the two connecting rings 2101 separates the two elastic rubber cores 2102 and the two tightly contacting silicon carbide abrasive layers 2103. Simultaneously, the connecting block 2105 is pulled out of the connecting groove 302, allowing one of the modular repair components 21 to be removed, facilitating the replacement of a new modular repair component 21 or the replacement of different types of modular repair components 21. By reversing the rotation of the screw block, the T-shaped threaded rod 308 rotates in the opposite direction, simultaneously causing the limiting threaded rod 309 to gradually rotate out of the threaded hole 207. The movement of the T-shaped threaded rod 308 pushes the concave block 307 to move, further pushing the double-rod movable part 306 and multiple reinforcing blocks 304 to move, thereby re-inserting the reinforcing rod 305 into the new connecting block 2105. Under the action of the switching mechanism 3, the modular repair component 21 can be quickly disassembled and assembled, or the positions of different types of modular repair components 21 can be changed to strengthen and repair different positions of the abrasive belt 111.

[0044] Example 3: Figures 1-5As shown, the grinding machine mechanism 1 includes a grinding machine housing 101. A PLC control system 102 is installed on one outer surface of the grinding machine housing 101. A conveying system 103 is installed inside the grinding machine housing 101. Two bases 105 are fixedly installed on both sides inside the grinding machine housing 101. A first drive system 106 is installed on one side of the top of the two bases 105. A grinding roller 107 is installed inside the first drive system 106. Two second drive systems 108 are installed on the top of the two bases 105. A drive roller 109 is installed inside each of the two second drive systems 108. A tensioning system 110 is installed on the top of each of the two second drive systems 108. The outer surface of each of the two sanding belts 111 is movably fitted with sanding belts 111. The interior of each sanding belt 111 contacts the bottom of the two drive rollers 109. Limiting strips 112 are fixedly installed on both sides of the front and rear surfaces of the two second drive systems 108 and the two tensioning systems 110. A dust extraction system 104 is installed on the rear wall inside the sanding machine housing 101. The first drive system 106 is used to drive the sanding rollers 107 to coarsely grind the surface of the roll flooring. The second drive system 108 is used to drive the drive rollers 109 to rotate, thereby rotating the sanding belts 111 to finely grind the coarsely ground roll flooring. There are two sanding belts 111, which are used for medium and fine grinding in stages.

[0045] In this embodiment, during use, the first drive system 106 and two second drive systems 108 are activated. The roll flooring is conveyed via the conveying system 103 and first reaches the grinding roller 107. The first drive system 106 drives the grinding roller 107 to rotate, performing initial grinding on the surface of the roll flooring. This coarse grinding stage quickly removes large defects. The two second drive systems 108 drive the drive roller 109 to rotate, causing the two grinding belts 111 to rotate rapidly, performing fine grinding on the coarsely ground roll flooring. The two grinding belts 111 achieve staged refinement of medium and fine grinding, greatly improving the grinding effect. Simultaneously, the dust collection system 104 is activated to collect dust particles. The grinding machine mechanism 1 achieves three-stage gradient grinding, improving grinding accuracy.

[0046] The overall mechanism works as follows: The cylinder 203 and laser rangefinder 204 are activated. The cylinder 203 moves the repair seat 205, and simultaneously, through the cooperation of the limit shaft 206 and the rotating cylinder 210, it pushes the overall repair roller composed of multiple modular repair components 21 towards the sanding belt 111. At the same time, the laser rangefinder 204 measures the distance change between itself and the repair seat 205. When the moving distance matches the set value, the PLC control system 102 controls the cylinder 203 to shut down. The conveying system 103 conveys the roll flooring to the sanding roller 107. The first drive system 106 drives the sanding roller 107 to rotate, performing initial sanding on the surface of the roll flooring. Two second drive systems 108 drive the drive roller 109 to rotate, causing the two sanding belts 111 to rotate rapidly, performing fine sanding on the coarsely sanded roll flooring. Simultaneously, the dust collection system 104 is activated to collect dust particles. The abrasive belt 111 contacts the repair roller, which rotates passively and synchronously with the abrasive belt 111. The fine silicon carbide abrasive material in the outer silicon carbide abrasive layer 2103 performs micro-cutting on the passivated abrasive on the surface of the abrasive belt 111, reshaping the sharp cutting surface of the abrasive. The elastic rubber core 2102 has flexible self-adaptive capabilities, which can adapt to the slight undulations on the surface of the abrasive belt 111, ensuring that the repair roller makes full contact with the abrasive belt 111, thereby better repairing the abrasive belt 111's polishing effect. Rotate the modular repair assembly 21 to align the two limiting threaded rods 309 with the two threaded holes 207. Then, temporarily fix the modular repair assembly 21 with one hand, and rotate the locking block at the connection between the limiting threaded rod 309 and the T-shaped threaded rod 308 with the other hand. This will cause the limiting threaded rod 309 to gradually enter the threaded hole 207. At the same time, the T-shaped threaded rod 308 will rotate and move forward, pulling the concave block 307 and the double-rod movable part 306 forward. This will also cause multiple reinforcing rods 305 to move out of the connecting block 2105. Repeat the above process to remove the reinforcing rods 305 in the other switching mechanism 3 from the corresponding connecting block 2105. Pull out the two connecting rings 2101 to separate the two elastic rubber cores 2102 and the two closely contacting silicon carbide abrasive layers 2103. At the same time, pull the connecting block 2105 out of the connecting groove 302. This allows one of the modular repair components 21 to be removed, making it convenient to replace a new modular repair component 21 or to change the position of a different type of modular repair component 21.

[0047] Among them, the conveying system 103, the dust collection system 104, the first drive system 106, the second drive system 108, the tensioning system 110, the cylinder 203, the laser rangefinder 204 and the PLC control system 102 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.
