Abstract
Description
Technical Field
[0001] This application relates to the field of abrasive brush technology, and more particularly to an abrasive brush for stone processing. Background Technology
[0002] Grinding brushes are essential tools for stone surface treatment. They work by using the friction between the abrasive on the brush and the stone surface to grind and polish the stone to achieve the desired surface effect. However, existing grinding brushes have a fixed bristle thickness, while stone grinding requires different steps. This means that after each grinding stage, the machine needs to be stopped and the appropriate grinding brush size needs to be replaced, which prolongs the overall stone processing time and reduces production efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a grinding brush for stone processing in order to solve the above-mentioned problems.

[0006] The recessed part is also provided with an installation groove, which is located between adjacent receiving grooves. A coarse grinding component is provided in the installation groove. The coarse grinding component includes a support rod, one end of which is installed in the installation groove, and the other end is connected to a storage tray. The storage tray has a storage groove, and a grinding block is movably installed on the storage groove.
[0007] When the grinding block is installed on the tray, part of the grinding block is at a height higher than the height of the brush bristles, while the tray is at a height lower than the height of the brush bristles.
[0008] Several mounting slots are provided so that the grinding blocks are distributed around the recessed area.
[0009] In one embodiment, the support base includes an upper seat and a lower seat, with the recess located on the upper seat;
[0010] The lower seat has several spaced slots, and the upper seat has a protrusion on the side away from the recessed part corresponding to the slot. When the bottom of the upper seat is in contact with the top of the lower seat, the protrusion is inserted into the slot, connecting the upper and lower seats.
[0011] In one embodiment, inclined ends are provided on both sides of the lower seat, and the area of the lower seat gradually increases from the end facing the upper seat to the other end away from the upper seat by the provision of inclined ends.
[0012] The lower section is designed to have a trapezoidal structure.
[0013] In one embodiment, a threaded groove is provided in the mounting groove, and a convex thread matching the threaded groove is provided on the outer periphery of the support rod.

[0017] In one embodiment, the grinding block is made of nylon.
[0018] The advantages or beneficial effects of the above technical solutions include at least the following:
[0019] This application discloses a grinding brush for stone processing. The brush bristles are installed in a receiving groove of a support base, and a support rod for a coarse grinding component is installed in a mounting groove of the support base. Since the support rod is connected to a tray for loading grinding blocks, the height of the grinding blocks is higher than the length of the brush bristles. Therefore, when the support base is installed on a polishing machine and the stone is being ground, the grinding blocks first contact the stone for coarse grinding. During the grinding process, the grinding blocks gradually wear down, reducing their thickness. After grinding for a period of time, the grinding blocks and brush bristles are brought to the same horizontal position, allowing the brush bristles to further grind the stone. By placing both the coarse grinding component and the brush bristles on the support base, two different levels of grinding precision can be achieved, improving grinding efficiency and solving the problem of existing grinding brushes having fixed grinding precision, which limits their application.

[0036] Reference Figures 1-6 A grinding brush for stone processing includes a support base 1, which serves as the basic support structure for the entire grinding brush, providing a stable mounting and working platform. Its shape and size are designed to be compatible with the stone polishing machine to ensure the grinding brush can be securely mounted on the equipment and remain stable during high-speed rotation or reciprocating motion. The support base 1 has a recess 11, within which are several receiving grooves 111 spaced apart. Each receiving groove 111 is filled with an adhesive and has brush bristles 2 mounted on it. The adhesive, which can be epoxy resin, provides high-strength bonding between the brush bristles 2 and the receiving grooves 111, ensuring that the brush bristles 2 will not fall off or shift during high-speed rotation or when subjected to resistance from the stone surface.
[0037] The recessed portion 11 is also provided with a mounting groove 112, which is located between adjacent receiving grooves 111. A coarse grinding component 3 is provided in the mounting groove 112. The coarse grinding component 3 includes a support rod 31. One end of the support rod 31 is installed in the mounting groove 112, and the other end is connected to a storage tray 32. The storage tray 32 has a storage groove 321, and a grinding block 33 is movably installed on the storage groove 321. The design of the recessed portion 11 provides space for the setting of the receiving groove 111 and the mounting groove 112, so that the bristle component 2 and the coarse grinding component 3 can be reasonably distributed on the base.
[0038] When the grinding block 33 is installed on the tray 32, part of the grinding block 33 is at a height higher than the height of the brush 2, while the tray 32 is at a height lower than the height of the brush 2. The grinding block 33 is made of nylon. When grinding, the grinding block 33 first comes into contact with the stone material. After grinding for a period of time, the grinding block 33 is worn. Then, the stone is ground again by the brush 2. The mesh number of the brush 2 is greater than that of the grinding block 33, thereby achieving different grinding precision. The brush 2 is made of metal and has a higher wear resistance than the grinding block 33.
[0039] The mounting groove 112 is provided with several grooves, so that the grinding blocks 33 are distributed around the recess 11. The design of the mounting groove 112 around the perimeter allows the coarse grinding parts 3 to effectively coarsely grind the surrounding area of the stone surface during the grinding process, ensuring that all parts of the stone surface can be coarsely ground first.
[0040] Based on the above structure, the brush bristle 2 and the coarse grinding component 3 are connected by installing them onto the receiving groove 111 and mounting groove 112 of the bearing base 1, respectively. Then, the bearing base 1 is installed on the grinding head of the polishing machine. Since the grinding block 33 in the coarse grinding component 3 is connected to the support rod 31 via the placement plate 32, the height of the grinding block 33 is higher than the length of the brush bristle 2. During the grinding operation, the grinding block 33 first contacts the stone and performs coarse grinding, removing larger defects and uneven parts from the stone surface. Because the grinding process is at high speed, the grinding block 33... As wear gradually occurs, when the grinding block 33 wears down to a certain extent and becomes parallel to the bristle part 2, the bristle part 2 can perform a second grinding on the stone after the initial grinding, removing the minor imperfections left during the coarse grinding process and making the stone surface smoother and more delicate. Since the support rod 31 in the coarse grinding part 3 is movably installed on the mounting groove 112, the grinding block 33 in the coarse grinding part 3 can be replaced after the final processing for use in the next processing. Through the cooperation of the bristle part 2 and the coarse grinding part 3, two grinding precisions can be achieved with a single grinding brush, solving the problem that traditional grinding brushes with only a single grinding precision need to be replaced multiple times, thus improving processing efficiency.
[0041] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 6 and Figure 7 The support base 1 includes an upper base 12 and a lower base 13. The recess 11 is located on the upper base 12. The upper base 12 is used to support the parts that need to be polished, and the lower base 13 is used to connect the grinding head of the polishing machine.
[0042] The lower seat 13 is provided with several spaced slots 131. The upper seat 12 is provided with a protrusion 121 on the side away from the recess 11, corresponding to the position of the slots 131. When the bottom end of the upper seat 12 is in contact with the top end of the lower seat 13, the protrusion 121 is inserted into the slot 131, so that the upper seat 12 and the lower seat 13 are connected. Through the mechanical snap-fit structure of the protrusion 121 and the slot 131, the upper seat 12 and the lower seat 13 can be quickly positioned and connected. Assembly can be completed without additional tools, so that the lower seat 13 can be replaced according to different polishing machine grinding head sizes without replacing the entire grinding brush.
[0043] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 The lower seat 13 has inclined ends 132 on both sides. The area of the lower seat 13 gradually increases from the end facing the upper seat 12 to the other end away from the upper seat 12, so that the cross-section of the lower seat 13 is set in a trapezoidal structure. The bottom area of the trapezoidal cross-section is larger than the top area, forming a stable structure that is "narrow at the top and wide at the bottom". When the lower seat 13 is installed on the grinding head and rotated for grinding, the larger bottom contact area can provide stronger anti-overturning torque, reduce the swaying of the base caused by centrifugal force, and ensure the stability of the grinding process.
[0044] The inclined end 132 has a raised textured portion 1321. Several raised textured portions 1321 are provided and spaced apart along the length direction of the inclined end 132. The raised textured portions 1321 form friction patterns on the inclined end 132. By increasing the roughness of the contact surface, the raised textured portions 1321 generate stronger static friction with the surface of the grinding head during installation, preventing the support base 1 from sliding due to centrifugal force or lateral force when rotating at high speed. In addition, the spaced raised textured portions 1321 maintain the structural strength of the inclined end 132 while avoiding the problem of loose fit caused by overall planar contact. At the same time, when there is slight deformation on the surface of the grinding head, the raised textured portions 1321 can still achieve effective support through high point contact, improving installation adaptability.
[0045] In one embodiment, reference is made to Figure 1 and Figure 4The mounting groove 112 is provided with a threaded groove 1121, and the outer periphery of the support rod 31 is provided with a convex thread 311 that matches the threaded groove 1121. Through the cooperation of the threaded groove 1121 and the convex thread 311, the support rod 31 is threadedly connected to the mounting groove 112. The threaded connection has precise pitch control, and the length of the support rod 31 extending out of the mounting groove 112 can be adjusted by rotating it, thereby precisely controlling the working height of the grinding brush. This adjustability adapts to the processing needs of stone with different thicknesses and hardnesses. Furthermore, the friction and mechanical meshing generated by the threaded engagement can effectively resist axial force and torque during the grinding process. At the same time, when the support rod 31 is worn, it can be replaced by disassembling the support rod 31 separately, reducing maintenance costs.
[0046] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 6 and Figure 7 A magnetic layer 1311 is provided inside the slot 131, and a magnetic block 1211 is provided at the bottom of the protrusion 121. The magnetic poles between the magnetic block 1211 and the magnetic layer 1311 attract each other. When the protrusion 121 is inserted into the slot 131, the protrusion 121 is magnetically connected to the slot 131 through the cooperation of the magnetic layer 1311 and the magnetic block 1211. When the protrusion 121 approaches the slot 131, the magnetic attraction automatically attracts and guides the alignment. The initial connection can be completed without precise alignment, achieving rapid pre-positioning. Furthermore, during the grinding process, equipment vibration may cause slight displacement of the buckle connection. The magnetic attraction can provide continuous axial clamping force to compensate for the gap caused by the tolerance of the mechanical buckle and reduce the relative shaking between components.
[0047] In one embodiment, reference is made to Figure 1 and Figure 3 The upper seat 12 has slots 122 on both sides. The slots 122 provide a fulcrum for the operator to apply force. By levering the principle, the pulling force required for separation is reduced. Compared with the direct prying method, the slots 122 have pre-set weak points, which can guide the direction of the separation force and prevent the edge of the upper seat 12 or lower seat 13 from being damaged due to uneven force, thus improving the convenience of disassembly.
[0048] In one embodiment, reference is made to Figure 4 An overflow hole 1111 is provided on two adjacent sets of receiving grooves 111, so that the interiors of the two sets of receiving grooves 111 are interconnected. The overflow hole 1111 is mainly designed to achieve fluid communication between the receiving grooves 111. When the adhesive is in the receiving groove 111, it can flow through the overflow hole 1111 to different receiving grooves 111, which can wet and fill the brush bristles 2 a second or even multiple times. This avoids the situation that the adhesive may not be fully wetted or the gaps may not be completely filled when the adhesive is first applied. The flowing adhesive can penetrate again, thereby enhancing the adhesion effect on the brush bristles 2.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0050] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
