Description

Technical Field

[0001] The invention relates to the technical field of drawer board processing, and in particular to an automated drawer board processing system. Background Art

[0002] Drawers are box-shaped components attached to furniture such as tables and cabinets that can be pulled out. Most of them are made of wood and are used to hold items. Drawers are composed of various drawer boards, such as drawer top boards, drawer side boards, back boards, and drawer bottom boards. Therefore, the processing quality of drawer boards is an important factor in determining the overall quality of drawers.

[0003] The processing of drawer boards is divided into cutting, grinding, edging, painting and other processes. Grinding the cut edges of drawer boards can achieve smooth and beautifying effects. In the existing drawer board processing system, it is already possible to grind the cut edges of irregular drawer boards at multiple angles, and no secondary adjustment or fixation is required during the grinding process, which improves the degree of automation of processing and production efficiency.

[0004] For example, a wood board processing edge grinding device with Chinese patent publication number CN118404452B includes a self-adjusting grinding mechanism, a center positioning mechanism, a clamping and fixing mechanism and a conveying mechanism. The self-adjusting grinding mechanism is fixedly arranged on the conveying mechanism. The self-adjusting grinding mechanism includes a mounting ring, a position adjustment mechanism and a multi-angle edge grinding mechanism. The mounting ring is fixedly arranged on the conveying mechanism, an annular gear ring is fixedly arranged on the upper wall of the mounting ring, the position adjustment mechanism is movably arranged on the mounting ring, the multi-angle edge grinding mechanism is movably arranged on the position adjustment mechanism, the center positioning mechanism is fixedly arranged on the conveying mechanism, and the clamping and fixing mechanism is fixedly arranged on the conveying mechanism.

[0005] This solution can grind all sides of the wood board without dead angles, and does not require position angle adjustment during processing, so it has a wide range of applications. However, it is not convenient to change the angle of the grinding roller according to the cut edge shape of the drawer board. Due to the different shapes of the drawer board sides, the angle of contact between the grinding roller and the drawer board during movement is also different. When the angle between the two is too small, it is easy to reduce the pressure of the grinding roller on the drawer board, which in turn causes quality problems such as reduced grinding effect, poor drawer board molding effect, and uneven paint surface. Summary of the invention

[0006] The purpose of the present invention is to provide an automated drawer board processing system, which can change the angle of the grinding roller according to the shape of the drawer board while achieving multi-angle grinding, so that it always maintains a nearly vertical state with the drawer board, improves the stability of the grinding pressure, and thus improves the processing effect and yield rate.

[0034] like Figures 1 to 10 As shown: A drawer board processing automation system includes the following steps: step 1: placing a drawer board body 13 on the top of a conveyor 1 and moving it, and the drawer board body 13 can be moved into a ring-shaped fixed frame 11; step 2: a fixing component 2 is provided on the conveyor 1, which can lift and fix the drawer board body 13 to keep the drawer board stable during the edge grinding process; step 3: a uniform speed driving component 4 is provided on the shell 32, which can drive the shell 32 to rotate slowly around the outer periphery of the drawer board body 13 and drive the grinding mechanism to grind in the reverse direction; step 4: the outer periphery of the drawer board body 13 is edged by the multi-angle grinding component 3, and the angle adjustment mechanism 33 provided on the shell 32 is used to automatically adjust the angle of the shell 32 during the edge grinding process, so that the shell 32 and the drawer board are aligned. The main bodies 13 always remain in a state close to being perpendicular to each other, which can stabilize the grinding pressure and improve the grinding effect: Step 5: After the grinding is completed, the shell 32 is pushed to reset by the hydraulic rod 313, and the length of the telescopic rod 31 is locked by the locking mechanism 35 to fix the position of the shell 32, which can avoid hindering the movement of the drawer board body 13. It also includes a conveying platform 1, a fixing component 2, a multi-angle grinding component 3 and a uniform speed driving component 4. The conveying platform 1 includes a pair of frames 10, an annular fixing frame 11 and a conveying mechanism 12. The two frames 10 are respectively located at both ends of the annular fixing frame 11, and the top of the frame 10 is fixedly connected to the bottom of the annular fixing frame 11, so that the conveying platform 1 becomes a segmented structure, which is convenient for the multi-angle grinding component 3 to move up and down during work. The conveying mechanism 12 is used to stably convey the drawer board body 13. The fixing component 2 is installed on the annular fixing frame 11. The fixing component 2 is used to fix the drawer board body 13. When the drawer board body 13 is edged, the drawer board body 13 is placed on the frame 10 and moved to the annular fixing frame 11 through the conveying mechanism 12. Then the fixing component 2 is activated to lift and fix the drawer board body 13 to keep the drawer board stable during the edge grinding process. The multi-angle grinding assembly 3 includes a rotating seat 30, a telescopic rod 31, a shell 32, an angle adjustment mechanism 33 and an edge grinding mechanism 34. The rotating seat 30 is fixedly installed on the fixed assembly 2, one end of the telescopic rod 31 is rotatably connected to the outer periphery of the rotating seat 30, the telescopic end of the telescopic rod 31 is rotatably connected to one end of the shell 32 close to the rotating seat 30, the angle adjustment mechanism 33 and the edge grinding mechanism 34 are both installed on the shell 32, the angle adjustment mechanism 33 is used to always maintain an angle of nearly ninety degrees between the shell 32 and the drawer board, the edge grinding mechanism 34 is used to grind the cut edges of the drawer board body 13, and the uniform speed drive assembly 4 is installed on the shell 32, and the uniform speed drive assembly 4 is used to drive the membrane edge grinding assembly to move at a uniform speed around the outer periphery of the drawer board.As the drawer board is lifted and fixed, the telescopic rod 31 of the multi-angle grinding assembly 3 contracts, causing the sanding belt 340 of the edge grinding mechanism 34 to come into contact with the edge of the drawer board, and then the edge grinding mechanism 34 is driven to work by the uniform speed driving mechanism to grind the cut edges of the drawer board body 13, while the shell 32 is slowly moved along the periphery of the drawer board body 13, so that the edges of different positions on the periphery of the drawer board body 13 can be ground. During the movement, the shell 32 can rotate around one end according to the angles of different positions at the edge of the drawer board body 13 through the operation of the angle adjustment mechanism 33, thereby driving the edge grinding mechanism 34 to adjust the angle at any time, so that it always maintains close to 90 degrees with the periphery of the drawer board body 13, so that the grinding force is balanced, and the edge grinding quality is further improved.

[0035] like Figures 1 to 4 As shown: The conveying mechanism 12 includes a plurality of shafts 120 and a plurality of rollers 121. The plurality of shafts 120 are horizontally spaced and distributed in two frames 10. The shafts 120 are rotatably connected to the inner wall of the frame 10. The inner wall of the roller 121 is coaxially connected to the outer periphery of the shafts 120. When the drawer board body 13 is placed on the conveying platform 1, the bottom of the drawer board body 13 fits the top of the roller 121. During processing, the drawer board body 13 is pushed so that the roller 121 and the shaft 120 rotate synchronously in the frame 10, which can reduce friction and easily move the drawer board body 13 to the annular fixing frame 11, which is convenient for batch processing. A through groove 110 is provided at the bottom of the annular fixing frame 11. The function is to facilitate the passage of the drawer board.

[0036] like Figures 1 to 7 As shown: The fixing assembly 2 includes a bidirectional screw 20, a guide rod 21, a pair of clamping arms 22 and a first motor 23. The bidirectional screw 20 passes through the annular fixing frame 11 and is rotatably connected thereto. The top of the first motor 23 is fixedly connected to the frame body 10. The output shaft of the first motor 23 passes through the frame body 10 and is coaxially connected to the bottom of the bidirectional screw 20. The clamping arm 22 includes an L-shaped rod 220 and a clamping plate 221. One end of the two L-shaped rods 220 are respectively threadedly connected to the top and bottom of the bidirectional screw 20. The thread grooves on the two L-shaped rods 220 are in opposite directions. The guide rod 21 passes through the annular fixing frame 11 and is fixedly connected thereto. The L-shaped rod 220 is slidably connected to the periphery of the guide rod 21. The top of the clamping plate 221 at the top is fixedly connected to the bottom of the other end of the top L-shaped rod 220. The bottom of the clamping plate 221 at the bottom is fixedly connected to the bottom of the rotating seat 30, and the bottom of the rotating seat 30 is fixedly connected to the top of the bottom L-shaped rod 220. The first motor 23 is powered on and its output shaft drives the bidirectional screw 20 to rotate. Through the threaded transmission between the bidirectional screw 20 and the L-shaped rod 220, the two clamping arms 22 are driven to slide in opposite directions along the guide rod 21. When the two clamping plates 221 are close to each other, the drawer board body 13 can be clamped and fixed, and the clamping direction is the up and down directions, so that the outer periphery of the drawer board is exposed for polishing. When the two clamping plates 221 are away from each other, the drawer board body 13 is released to enable it to move.

[0037] like Figures 1 to 8 As shown: The telescopic rod 31 includes a sleeve 310, a slide bar 311, a pair of tension springs 312 and a hydraulic rod 313. One end of the sleeve 310 is rotatably connected to the outer periphery of the rotating seat 30. One end of the slide bar 311 passes through the side wall of the other end of the sliding sleeve and is slidably connected thereto. One end of the tension spring 312 is fixedly connected to the slide bar 311. The other end of the tension spring 312 is fixedly connected to the inner wall of the sleeve 310. One end of the hydraulic rod 313 is fixedly connected to the inner wall of the sleeve 310. The telescopic end of the hydraulic rod 313 conflicts with the slide bar 311, so that the hydraulic rod 313 works, and its telescopic end squeezes the slide bar 311 to push it The sliding sleeve is pushed out to make the shell 32 move away from the rotating seat 30, and the tension spring 312 is stretched. At this time, the shell 32 is at a longer distance from the clamping plate 221, and the length of the telescopic rod 31 is locked by the locking mechanism 35. Then the telescopic end of the hydraulic rod 313 retracts and returns to its original position. When the fixing component 2 clamps the drawer board body 13, the locking mechanism 35 is unlocked, and the tension spring 312 rebounds to shorten the telescopic rod 31, thereby making the shell 32 close to the drawer board body 13, so that the edging mechanism 34 and the drawer board body 13 conflict with each other, and can adapt to drawer board bodies 13 of different sizes. The angle adjustment mechanism 33 includes a pair of rolling rollers 330, a pair of support rods 331, multiple rotating shafts 332 and multiple torsion springs 333. The two support rods 331 are symmetrically distributed on both sides of the shell 32. The bottom of one end of the support rod 331 is rotatably connected to the top of the end of the shell 32 away from the telescopic rod 31 through the rotating shaft 332. The bottom of the rolling roller 330 is rotatably connected to the other end of the support rod 331. The bottom of the end of the shell 32 close to the telescopic rod 31 is rotatably connected to the top of the other end of the sliding rod 311 through the rotating shaft 332. The torsion spring 333 is sleeved on the periphery of the rotating shaft 332. The two ends of the torsion spring 333 at the top of the shell 32 are respectively fixedly connected to the top of the shell 32 and the bottom of the support plate, and the two ends of the torsion spring 333 at the bottom of the shell 32 are respectively fixedly connected to the bottom of the shell 32 and the top of the sliding rod 311. When the extension rod 31 is shortened, the rolling roller 330 first contacts the cut edge of the drawer board body 13. As the extension rod 31 continues to shorten, the drawer board body 13 squeezes the rolling roller 330, causing the two rolling rollers 330 to roll to both sides respectively. The support rod 331 rotates around the rotating shaft 332, the torsion spring 333 is twisted and maintains a rebound trend, and the shell 32 continues to approach the drawer board body 13 until the sanding belt 340 and the drawer board body 13 conflict with each other. At this time, the shell 32 is pushed by the support rods 331 on both sides and is at an angle perpendicular to the cut edge of the drawer board body 13. As the shell 32 rotates around the drawer board body 13, the extension rod 31 rotates around the rotating seat 30, and the edge grinding mechanism 34 grinds the drawer board at an angle. In this process, the rolling roller 330 always conflicts with the outer periphery of the drawer board body 13, pushing the shell 32 to rotate around the bottom rotating shaft 332, so that it always remains close to perpendicular to the drawer board body 13, thereby stabilizing the grinding force and improving the grinding effect.When the grinding is completed and the edge grinding mechanism 34 is separated from the drawer board body 13, the torsion spring 333 on the outer periphery of the bottom rotating shaft 332 rebounds, so that the shell 32 rotates and returns to its original position, which is convenient for the subsequent movement of the drawer board body 13 and continuous processing.

[0038] like Figures 1 to 10 As shown: The edge grinding mechanism 34 includes a sanding belt 340, a supporting roller 341, a driving roller 342 and a pair of squeezing rollers 343. The bottom of the driving roller 342 is rotatably connected to the end of the top of the housing 32 away from the telescopic rod 31, and the bottom of the supporting roller 341 is rotatably connected to the end of the top of the housing 32 close to the telescopic end. The sanding belt 340 is sleeved on the outer periphery of the supporting roller 341 and the driving roller 342. Two squeezing rollers 343 are symmetrically arranged on both sides of the top of the housing 32 and can be horizontally moved. The outer periphery of the squeezing roller 343 is in conflict with the inner wall of the sanding belt 340. The sanding belt 340 is supported by the driving roller 342 and the supporting roller 341. The sanding belt 340 is driven to approach and conflict with the drawer board body 13 by moving the housing 32. Then, the driving roller 342 is rotated to drive the sanding belt 340 to rotate, so that the drawer board body 13 can be polished. By adjusting the spacing between the two squeezing rollers 343, the sanding belt 340 is squeezed from the inside to the outside, so that the sanding belt 340 maintains tension, which is convenient for polishing.

[0039] like Figures 1 to 10 As shown: The edge grinding mechanism 34 also includes a knob 344, a first gear 345, a pair of bases 346 and a pair of racks 347. The top of the knob 344 passes through the bottom wall of the housing 32 and is rotatably connected thereto. The first gear 345 is coaxially connected to the periphery of the knob 344.
