Abstract
Description
Technical Field
[0001] This application relates to the field of quartz stone processing technology, and in particular to a device for grinding the edges and corners of quartz stone slabs. Background Technology
[0002] Quartz stone, as we commonly refer to it, is a new type of artificial stone made of over 90% quartz crystals, resin, and other trace elements. Due to its resistance to aging, high fire resistance, and durability, quartz stone is widely used in public buildings and home decoration.
[0003] To improve the aesthetics and safety of quartz slabs during use, it is usually necessary to bevel and polish the four corners. The common method is to manually bevel and polish the corners with a handheld beveling machine. However, manual beveling is greatly affected by human factors, resulting in poor consistency, affecting product quality, and also causing a heavy workload for workers and low processing efficiency. Utility Model Content
[0004] To address the issues of inconsistent quality, high labor load, and low processing efficiency caused by manual chamfering and polishing methods which are heavily influenced by human factors, this application provides a quartz slab edge polishing device.
[0005] The quartz slab edge polishing device provided in this application adopts the following technical solution:
[0006] A quartz slab edge polishing device includes a conveyor frame, a first slider, a second slider, and positioning blocks. Rotary rollers are spaced apart along the length of the conveyor frame and are rotatably connected to it. The first and second sliders are slidably connected relative to each other along the width of the conveyor frame. The conveyor frame is equipped with a driving component for driving the first and second sliders closer together or further apart. The positioning blocks are respectively disposed on the first and second sliders. An arc-shaped groove is formed on each positioning block, and a sliding mounting block is slidably engaged within the arc-shaped groove. A polishing mechanism is provided on each sliding mounting block. A moving component is provided on each positioning block for driving the sliding mounting block to move.
[0007] By adopting the above technical solution, the rotating roller can rotate on the conveyor frame, which can convey quartz slabs; the drive component can drive the first slider and the second slider to slide relative to each other in the width direction of the conveyor frame, so that the two move closer or further apart, thereby driving the positioning block to move to clamp and fix quartz slabs of different sizes; the moving component can drive the sliding mounting block to slide in the arc-shaped groove of the positioning block, thereby driving the grinding mechanism to move and realize the chamfering and grinding of the edges and corners of the quartz slabs; in the chamfering and grinding of quartz slabs, the positioning accuracy is high and the degree of automation is high, which improves the problem that the manual chamfering and grinding method is greatly affected by human factors, resulting in poor consistency, affecting product quality, and causing high labor load and low processing efficiency for workers.
[0008] Optionally, the grinding mechanism includes a first rotating motor and a grinding wheel. The first rotating motor is vertically mounted on a sliding mounting block, and the grinding wheel is connected to the rotating shaft of the first rotating motor.
[0009] By adopting the above technical solution, the grinding wheel is driven to rotate by the first rotating motor set vertically on the sliding mounting block, which can realize the grinding of the edges and corners of quartz stone slabs. The structure is simple and easy to use.
[0010] Optionally, two arc-shaped grooves are symmetrically formed on the positioning block, and each arc-shaped groove is slidably fitted with a sliding mounting block.
[0011] By adopting the above technical solution, two quartz stone slabs can be clamped and fixed at the same time by the positioning block. The grinding mechanism on the two sliding mounting blocks on the same positioning block can be used to bevel and grind the corners of different quartz stone slabs, which significantly improves the grinding efficiency.
[0012] Optionally, the moving component includes a moving plate and two connecting rods. The moving plate is slidably connected to the positioning block along the width direction of the conveyor frame. One end of each of the two connecting rods is rotatably connected to the moving plate, and the other end of each of the two connecting rods is rotatably connected to a sliding mounting block in a grinding mechanism. The positioning block is provided with a moving component for driving the moving plate to move.
[0013] By adopting the above technical solution, the moving plate is driven to slide on the positioning block along the width direction of the conveyor frame by the moving component. Since one end of the two connecting rods is rotatably connected to the moving plate and the other end is rotatably connected to the sliding mounting block in a grinding mechanism, when the moving plate slides, it will drive the two connecting rods to rotate, thereby pushing the sliding mounting block to slide in the arc-shaped groove, realizing the adjustment of the position of the grinding mechanism, and enabling more flexible grinding of the edges and corners of the quartz stone slab.
[0014] Optionally, the moving component includes a screw and a second rotating motor. The screw is rotatably connected to the positioning block about the width of the conveyor frame. The second rotating motor is mounted on the positioning block. The rotating shaft of the second rotating motor is connected to the screw. The screw passes through the moving plate and is threadedly connected to the moving plate.
[0015] By adopting the above technical solution, the second rotating motor is started, which drives the screw to rotate. Since the screw is threadedly connected to the moving plate, and the moving plate cannot rotate with the screw, the moving plate can slide on the positioning block along the width direction of the conveyor frame, and the movement of the moving plate is stable and reliable.
[0016] Optionally, the drive assembly includes a double-ended lead screw and a third rotating motor. The third rotating motor is mounted on the conveyor frame along the width direction of the conveyor frame. The double-ended lead screw is coaxially connected to the rotating shaft of the third rotating motor. The two ends of the double-ended lead screw are respectively threaded onto the first slider and the second slider. The double-ended lead screw is threadedly connected to both the first slider and the second slider.
[0017] By adopting the above technical solution, when the third rotating motor is started, the third rotating motor drives the double-ended lead screw connected to it to rotate. Since the double-ended lead screw is threadedly connected to the first slider and the second slider, the rotation of the double-ended lead screw can make the first slider and the second slider move closer or further away from each other along the width direction of the conveyor frame, thereby realizing the adjustment of the grinding position of the edges and corners of quartz stone slabs of different sizes.
[0018] Optionally, the positioning blocks have anti-slip textures on the side closest to each other.
[0019] By adopting the above technical solution, anti-slip textures are opened on the side of the positioning blocks that are close to each other, which can increase the friction with the quartz stone slab, better fix the quartz stone slab, prevent the quartz stone slab from sliding during the polishing process, and improve the polishing accuracy and stability.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. After the quartz slab is placed on the rotating roller on the conveyor frame, the first and second sliders are driven to move closer to each other by the drive assembly, so that the two positioning blocks clamp and fix the quartz slab. Then, the sliding mounting block is driven to slide along the arc-shaped groove by the moving assembly, so that the grinding mechanism on the sliding mounting block can bevel and grind one side of the corner of the quartz slab. The quartz slab can not only be quickly and accurately positioned and fixed, but also complete the automated beveling and grinding operation. This improves the problem that the manual beveling and grinding method is greatly affected by human factors, resulting in poor consistency, affecting product quality, and causing heavy labor load and low processing efficiency for workers.
[0022] 2. Two arc-shaped grooves are symmetrically opened on the positioning block. Each arc-shaped groove is equipped with a sliding mounting block, which allows the chamfering and grinding of one side corner of the cool quartz stone slab to be completed at the same time, significantly improving grinding efficiency.
[0023] 3. The arrangement of the moving plate, connecting rod, and moving parts allows the moving plate to slide along the width of the conveyor frame via the moving parts, which in turn drives the connecting rod to rotate. This, in turn, drives the sliding mounting block, which is rotatably connected to the other end of the connecting rod, to slide along the arc-shaped groove. The structure is relatively simple, and the movement of the sliding mounting block is stable and reliable. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a device for polishing the edges and corners of quartz slabs. (Refer to...) Figure 1-2The quartz slab edge polishing device includes a conveyor frame 1, a first slider 2, a second slider 3, and a positioning block 4. Multiple rotating rollers 11 are spaced along the length of the conveyor frame 1, and are rotatably connected to the conveyor frame 1 around its width. The numerous rotating rollers 11, evenly spaced along the length of the conveyor frame 1, rotate together to form a continuous conveying plane. When a quartz slab is placed on a rotating roller 11, the rotation of the roller 11 drives the quartz slab forward. In practical use, sprockets can be coaxially connected to the rotating rollers 11, with chains wound around all the sprockets. A motor drives the sprockets to rotate, thus achieving synchronous rotation of all the rotating rollers 11 in the same direction, thereby realizing automated transport of the quartz slab.
[0031] Specifically, the conveyor frame 1 has dovetail grooves along its width. The bottoms of the first slider 2 and the second slider 3 each have dovetail blocks 21 that match the dovetail grooves. The first slider 2 and the second slider 3 are slidably engaged within the dovetail grooves via the dovetail blocks 21, thus enabling the first slider 2 and the second slider 3 to slide relative to each other on the conveyor frame 1 along its width. The conveyor frame 1 is equipped with a drive assembly for driving the first slider 2 and the second slider 3 to move closer or further apart. Positioning blocks 4 are welded and fixed to the first slider 2 and the second slider 3 respectively, and can move with the sliders. Anti-slip textures 41 are provided on the side of the positioning blocks 4 that are close to each other.
[0032] Two arc-shaped grooves 42 are symmetrically provided on the positioning block 4. The arc-shaped grooves 42 are flared outward from the direction close to the conveyor frame 1 to the direction away from the conveyor frame 1 along the width direction. The arc-shaped grooves 42 are machined, and their curvature is designed according to the radius required for chamfering and grinding, and are generally arc-shaped. Sliding mounting blocks 5 are slidably engaged in the arc-shaped grooves 42. The positioning block 4 is provided with a moving component for driving the sliding mounting blocks 5 to move. Each sliding mounting block 5 is provided with a grinding mechanism, which specifically includes a first rotating motor 51 and a grinding wheel 52. The first rotating motor 51 is vertically bolted to the top of the sliding mounting block 5, and the grinding wheel 52 is coaxially fixed to the rotating shaft at the bottom of the first rotating motor 51. The first rotating motor 51 is usually a high-speed motor, which can drive the grinding wheel 52 to rotate quickly. The grinding wheel 52 can be selected with different grit and materials according to the grinding needs. For example, the corundum grinding wheel 52 is suitable for rough grinding of general quartz slabs, while the diamond grinding wheel 52 has high hardness and strong grinding ability, and is suitable for fine grinding of quartz slabs.
[0033] In use, the quartz slab is placed directly on the rotating roller 11 of the conveyor frame 1. As the rotating roller 11 rotates, the quartz slab is transported to the side wall where it abuts against the grinding wheel 52. At this time, the drive assembly drives the first slider 2 and the second slider 3 to move closer together until the positioning block 4 abuts against the side walls on both sides of the quartz slab, thereby achieving clamping and fixing of quartz slabs of different sizes. Then, the first rotating motor 51 is started to drive the grinding wheel 52 to rotate for grinding. Then, the moving assembly drives the sliding mounting block 5 to slide along the arc-shaped slide groove 42, thereby achieving chamfering and grinding of one edge corner of the quartz slab. The quartz slab has high positioning accuracy, high grinding accuracy and high efficiency, which improves the problem that manual chamfering and grinding is greatly affected by human factors, resulting in poor consistency, affecting product quality, and causing heavy labor load and low processing efficiency for workers. In actual use, two quartz stone slabs can be clamped at once by the positioning block 4. Through the two sets of sliding mounting blocks 5 on the positioning block 4 and the grinding mechanism thereon, the chamfering and grinding operation of the two quartz stone slabs can be carried out at the same time, which significantly improves the grinding efficiency.
[0034] Specifically, refer to Figure 2 The drive assembly includes a double-ended lead screw 12 and a third rotary motor 13. The third rotary motor 13 is fixedly mounted on the conveyor frame 1 along its width. The double-ended lead screw 12 is coaxially connected to the rotating shaft of the third rotary motor 13. Both ends of the double-ended lead screw 12 pass through the first slider 2 and the second slider 3, respectively, and are threadedly connected to both sliders 2 and 3. The third rotary motor 13 is typically a stepper motor, which can precisely control the rotation angle and number of revolutions. When the third rotary motor 13 starts, it drives the double-ended lead screw 12 to rotate. Because the threads at both ends of the lead screw are in opposite directions, the first slider 2 and the second slider 3 move closer to or further apart along the width of the conveyor frame 1. Through the transmission of the double-ended lead screw 12, the rotational motion of the rotating shaft of the third rotary motor 13 is converted into linear motion of the first slider 2 and the second slider 3 along the length of the double-ended lead screw 12, resulting in more stable and reliable movement with high precision, achieving precise clamping and fixing of the quartz slab.
[0035] For example, refer to Figure 1 and Figure 3The moving assembly includes a moving plate 6 and two connecting rods 7. The moving plate 6 is slidably connected to the positioning block 4 along the width direction of the conveyor frame 1. One end of each of the two connecting rods 7 is rotatably connected to the moving plate 6, and the other end of each connecting rod 7 is rotatably connected to a sliding mounting block 5 in a grinding mechanism. The positioning block 4 is provided with a moving component for driving the moving plate 6 to move. In use, the moving component drives the moving plate 6 to slide along the width direction of the conveyor frame 1, which in turn causes the two connecting rods 7 on the moving plate 6 to swing, thereby pulling the sliding mounting blocks 5 rotatably connected to the connecting rods 7 to slide along their respective arc-shaped sliding grooves 42. The two sliding mounting blocks 5 on the positioning block 4 are synchronously driven to move by a single power source. The structure is simple, easy to use, and saves on power costs.
[0036] Specifically, the moving parts include a screw 8 and a second rotating motor 9. The screw 8 is rotatably connected to the positioning block 4 about the width of the conveyor frame 1. The second rotating motor 9 is bolted to the positioning block 4, and its rotating shaft is connected to the screw 8. The screw 8 passes through the moving plate 6 and is threadedly connected to it. The second rotating motor 9 can be a servo motor, which can precisely control the rotation of the screw 8, thereby moving the moving plate 6 along the axis of the screw 8. Through the connecting rod 7, the sliding mounting block 5 moves within the arc-shaped groove 42, realizing the position adjustment of the grinding mechanism.
[0037] The implementation principle of this embodiment is as follows: When grinding the edges and corners of a quartz slab, the quartz slab is first placed on the rotating roller 11 of the conveyor frame 1. The rotating roller 11 rotates and conveys the quartz slab to one side to abut against the grinding wheel 52 for initial positioning. Then, the third rotating motor 13 is started, driving the double-headed lead screw 12 to rotate, causing the first slider 2 and the second slider 3 to move closer to each other. The positioning block 4 clamps the quartz slab, achieving precise clamping and positioning of the quartz slab. Next, the first rotating motor 51 is started, driving the grinding wheel 52 to rotate. At the same time, the second rotating motor 9 is started, driving the moving plate 6 to move through the screw 8. The connecting rod 7 drives the sliding mounting block 5 to slide within the arc-shaped groove 42, so that the grinding mechanism can chamfer and grind the edges and corners of the quartz slab. This device conveys quartz slabs via rotating rollers 11 on a conveyor frame 1. The drive assembly adjusts the spacing of positioning blocks 4 to accommodate slabs of different widths. The grinding mechanism and moving assembly can efficiently and precisely chamfer the edges and corners of the quartz slabs, adapting to quartz slabs of different shapes and sizes. Compared with existing technologies, it improves upon the problems of manual chamfering being greatly affected by human factors, resulting in poor consistency, affecting product quality, and causing heavy labor load and low processing efficiency for workers.
[0038] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
