Description

Technical Field

[0001] This utility model relates to the technical field of board grinding equipment, and in particular to a device for grinding the edges of boards used in cabinets. Background Technology

[0002] In the field of cabinet manufacturing, edge sanding of boards is a key process to ensure the appearance quality and structural stability of the cabinet. With the diversification of market demand, the boards used for large wardrobes are usually taller, while the boards used for small bedside tables are relatively shorter.

[0003] In existing edge grinding devices for sheet metal, the grinding roller, as the core grinding component, often has relatively fixed specifications. In actual production, due to the different heights of the sheet metal, not all grinding rollers can be fully utilized during grinding. Especially when the sheet metal is short, the upper part of the grinding roller is completely unused, which will lead to resource waste over time. In order to adapt to the use of different sheet metal, existing grinding devices are equipped with additional feeding mechanisms for the grinding roller to achieve precise contact between the grinding roller and the edge of the sheet metal and avoid resource waste. However, these feeding mechanisms have complex structures, which increases the manufacturing cost and maintenance difficulty of the equipment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides an embodiment of a cabinet board edge grinding device, including a grinding platform 1 and a clamping assembly 2. Grinding assemblies 3 are arranged on both sides of the clamping assembly 2, and a cleaning assembly 4 is arranged below the clamping assembly 2. The grinding assembly 3 includes a mounting frame 31, a motor 32, a turntable 33, a fixing column 34, a hexagonal groove 35, a hexagonal prism 36, a mounting groove 37, and a positioning plate 38. A rotating shaft 39 is rotatably connected to the center of the positioning plate 38. A bolt 311 is fixedly connected to the bottom surface of the rotating shaft 39. A fixing plate 312 is threadedly connected to the surface of the bolt 311. A connecting rod 313 is rotatably connected to both sides of the fixing plate 312. A pin 314 is rotatably connected between the opposing surfaces of the two connecting rods 313. Limit blocks 3 are fixedly connected to both sides of the pin 314. 15. The hexagonal prism 36 has grooves 316 on its sidewalls, and the fixed column 34 has evenly spaced insertion grooves 310 on its inner wall. The positioning plate 38 has a positioning column 317 fixedly connected to its bottom. A grinding roller 318 is fitted onto the surface of the fixed column 34, and the top of the grinding roller 318 has a positioning groove 319. The output shafts of the two motors 32 rotate in opposite directions. Both motors 32 are fixedly connected to the bottom surface of the mounting bracket 31. The output shafts of the motors 32 are fixedly connected to the bottom surface of the turntable 33 via couplings. The fixed column 34 is fixedly connected to the top surface of the turntable 33. Hexagonal grooves 35 are all formed on the top surface of the fixed column 34. The hexagonal prism 36 is slidably connected inside the hexagonal grooves 35. The mounting grooves 37 are all formed on the bottom surface of the hexagonal prism 36. On the surface of the plate, the positioning discs 38 are all fixedly connected to the top surface of the hexagonal prism 36, the pins 314 are all slidably connected to the inside of the slide groove 316, and the ends of the pins 314 away from the hexagonal prism 36 are all inserted into the inside of the insertion groove 310. The positioning pins 317 are all slidably connected to the inside of the positioning groove 319. The inner wall surfaces of the slide groove 316 and the insertion groove 310 are all provided with limiting grooves that are compatible with the limiting block 315. Before grinding the edge of the plate to be ground, first turn the rotating shaft 39 to drive the bolt 311 to rotate. Since the pins 314 are slidably connected to the inside of the slide groove 316, they have a limiting effect on the fixing plate 312. Therefore, the rotation of the bolt 311 will not drive the fixing plate 312 to rotate. The fixing plate 312 is threadedly connected to the bolt 311. Rotation causes the fixed plate 312 to move up and down. First, the fixed plate 312 moves upwards. This movement drives the connecting rod 313, causing the pin 314 to slide inside the groove 316. This disengages the end of the pin 314 away from the hexagonal prism 36 from the insertion slot 310. During this process, the limiting block 315 prevents the pin 314 from moving excessively and disengaging from the groove 316. Pulling the rotating shaft 39 upwards then causes the hexagonal prism 36 to slide out of the hexagonal slot 35 via the positioning plate 38. At this point, a suitable grinding roller 318 can be selected based on the height of the material to be ground. The selected grinding roller 318 is then fitted onto the surface of the fixed post 34. Finally, the positioning post 317 is aligned with the positioning slot 319.The hexagonal prism 36 is slid back into the hexagonal groove 35. At this time, the positioning pin 317 inserts into the positioning groove 319. When the bottom surface of the positioning plate 38 coincides with the top surface of the selected grinding roller 318, the rotating shaft 39 is turned in the reverse direction, causing the bolt 311 to rotate. The rotation of the bolt 311 causes the fixing plate 312 to move downwards. Due to the movement of the fixing plate 312, the connecting rod 313 moves, thereby causing the pin 314 to slide into the corresponding insertion groove 310. This allows for the selection of a suitable grinding roller 318 based on the height of the material to be ground, avoiding waste of the grinding roller 318. Furthermore, it eliminates the need for an additional feeding mechanism for the grinding roller 318, saving equipment costs. After installation, the motor 32 drives the grinding roller 318 to rotate, and through the coordinated use of the clamping assembly 2, the grinding assembly 3, and the cleaning assembly 4, the edges of the material to be ground are ground.

[0024] Please see Figures 1-6 The clamping assembly 2 includes a conveyor belt, a drive unit, and a pressing and clamping device. The cleaning assembly 4 includes mounting blocks 41 located on both sides of the bottom of the clamping assembly 2. A fixing rod 42 is fixedly connected between the opposing surfaces of the two mounting blocks 41. A brush 43 is fixedly connected to the top surface of the fixing rod 42. The end of the brush 43 away from the fixing rod 42 abuts against the bottom surface of the conveyor belt in the clamping assembly 2. The conveyor belt is responsible for transporting the material to be polished to the polishing area. The drive unit is used to drive the movement of the conveyor belt. The pressing and clamping device is used to position and guide the material during transport to prevent it from deviating from the preset route. During the polishing process of the polishing assembly 3 polishing the edge of the material, some polishing debris will fall onto the conveyor surface. As the conveyor belt moves, the brush 43 will clean the surface of the conveyor belt to prevent the debris from affecting the work. This allows for efficient operation and extends the service life of the conveyor belt. The mounting frame 31 includes a stabilizing frame 301, with mounting discs 302 positioned between each pair of stabilizing frames 301. Each stabilizing frame 301 has a threaded hole 303 on its surface. An adjusting threaded rod 304 is rotatably connected to the bottom surface of the mounting disc 302. The adjusting threaded rod 304 is threaded into the threaded hole 303. When the upper part of the grinding roller 318 needs to be utilized, the adjusting threaded rod 304 can be turned. Since the adjusting threaded rod 304 is threaded into the threaded hole 303 and rotatably connected to the bottom surface of the mounting disc 302, the height of the mounting disc 302 can be adjusted when the adjusting threaded rod 304 is rotated, thereby adjusting the height of the entire grinding assembly 3 and making full use of all parts of the grinding roller 318.

[0025] Working principle: In use, first install and adapt the grinding roller 318. Tighten the rotating shaft 39 at the center of the positioning plate 38. The rotating shaft 39 drives the bolt 311 fixed on the bottom surface to rotate. Because the pin 314 slides within the groove 316 on the side wall of the hexagonal prism 36, it limits the fixing plate 312. The fixing plate 312 is threadedly connected to the bolt 311. The rotation of the bolt 311 causes the fixing plate 312 to move upwards. The movement of the fixing plate 312 drives the connecting rod 313, which is rotatably connected on both sides, to move. The connecting rod 313 drives the pin 314, which is rotatably connected between the two opposing surfaces, to slide within the groove 316. The limiting blocks 315 on both sides of the pin 314 slide within the limiting grooves opened in the groove 316 and the inner wall of the insertion groove 310 of the fixing post 34, preventing... If the pin 314 moves too far and disengages from the slide groove 316, causing the end of the pin 314 away from the hexagonal prism 36 to disengage from the insertion groove 310, then the rotating shaft 39 is pulled upwards, causing the hexagonal prism 36 to slide out of the hexagonal groove 35 at the top of the fixed post 34 via the positioning plate 38. A suitable grinding roller 318 is selected based on the height of the material to be ground, and the grinding roller 318 is fitted onto the surface of the fixed post 34, aligning the positioning post 317 at the bottom of the positioning plate 38 with the positioning groove 319 at the top of the grinding roller 318. The hexagonal prism 36 is then slid back into the hexagonal groove 35, and the positioning post 317 is inserted into the positioning groove 319. When the bottom surface of the positioning plate 38 coincides with the top surface of the grinding roller 318, the rotating shaft 39 is turned in the opposite direction, causing the bolt 311 to rotate in the opposite direction, causing the fixed plate 312 to move downwards. The movement of the connecting rod 313 causes the pin 314 to slide into the corresponding insertion slot 310, completing the installation of the grinding roller 318. After installation, the two motors 32 at the bottom of the mounting frame 31 are activated. The output shafts of the two motors 32 rotate in opposite directions, and the output shafts of the motors 32 drive the turntable 33 to rotate through the coupling. The turntable 33 drives the fixed column 34 fixed on the top surface to rotate, and the fixed column 34 drives the hexagonal prism 36 and the positioning plate 38 to rotate. The positioning plate 38 drives the grinding roller 318 to rotate through the positioning column 317. At the same time, the clamping assembly 2 works, and the conveyor belt moves under the drive of the drive device, conveying the material to be ground to the grinding area. The pressing clamping device positions and guides the material during conveying to prevent the material from deviating from the preset path, so that the material... The edge contacts the grinding roller 318 for grinding. When the upper part of the grinding roller 318 needs to be utilized, the adjusting threaded rod 304 can be turned. Since the adjusting threaded rod 304 is threaded inside the threaded hole 303 and rotatably connected to the bottom surface of the mounting plate 302, the height of the mounting plate 302 can be adjusted when the adjusting threaded rod 304 is rotated, thereby adjusting the height of the entire grinding assembly 3. This allows full utilization of all parts of the grinding roller 318. During the grinding process, some of the grinding debris falls onto the surface of the conveyor belt. As the conveyor belt moves, the brush 43 on top of the fixing rod 42 fixed between the mounting blocks 41 on both sides of the bottom of the clamping assembly 2 in the cleaning assembly 4 cleans the surface of the conveyor belt.The end of brush 43 furthest from the fixed rod 42 rests against the bottom surface of the conveyor belt, sweeping away debris to prevent it from affecting operation and extending the service life of the conveyor belt.
