Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0032] Please refer to Figures 1 - 7As shown in the figure, the utility model relates to an edge grinding device for furniture raw materials with angle locking, which includes a frame 1. On one side of the inner wall of the frame 1, a first support plate 2 is installed. On the other side of the inner wall of the frame 1, a second support plate 3 is installed. A driving structure 4 is installed on the inner wall of the frame 1. On one side of the driving structure 4, a fixing structure 5 is installed. And a grinding structure 6 is installed on the fixing structure 5;

[0033] The first support plate 2 approaches the second support plate 3 to fix the plate by the second support plate 3 and the first support plate 2. The first support plate 2 and the second support plate 3 are in sliding fit to enable the first support plate 2 and the second support plate 3 to rotate synchronously on the frame 1 for angle adjustment of the plate. The driving structure 4 is used to drive the grinding structure 6 to move through the fixing structure 5 to contact the plate, so as to realize grinding of the plate.

[0034] By installing the first support plate 2 and the second support plate 3 on the frame 1, during edge grinding operation, the plate can be placed on them. The plate is firmly fixed by the first support plate 2, and the second support plate 3 can adjust the fixed plate at multiple angles. Then, the driving structure 4 is driven to drive the grinding structure 6 on the fixing structure 5 to contact the edge of the plate for edge grinding operation. Furthermore, the angle of the plate can be adjusted in multiple ways, enabling chamfers at different angles to be ground. And when the angle of the plate changes and the distance changes, the driving structure 4 can also drive the grinding structure 6 to contact the edge of the plate for grinding, increasing its flexibility.

[0035] In the utility model, the first support plate 2 can firmly fix the plate placed above, preventing it from loosening. The second support plate 3 can change the angle of the plate. Then, the driving structure 4 drives the grinding structure 6 to grind the edge of the plate, enabling flexible grinding, realizing grinding of the plate at variable multiple angles, achieving grinding of chamfers at different angles, no longer requiring manual operation, improving work efficiency, and the device has a simple structure and low cost, and can be better adapted to small factories.

[0036] In one embodiment, for the above-mentioned first support plate 2, the first support plate 2 includes an adjusting screw 7. The adjusting screw 7 penetrates through the inner wall of the frame 1 and extends to the outside. One end of the outer part of the adjusting screw 7 penetrates through and is threadedly installed with a nut 8. A fixing groove 9 is formed on the outer surface of the nut 8. Two fixing frames 10 are installed on one side of the frame 1. One ends of the fixing frames 10 are both in the fixing groove 9. A rotating plate 11 is installed on the nut 8. One end of the rotating plate 11 is installed with a rotating handle 12. One end of the adjusting screw 7 inside the inner wall of the frame 1 is rotatably installed with a first L-shaped fixing plate 13.

[0037] By rotating the rotating handle 12, it drives the nut 8 to rotate through the rotating plate 11. Since the nut 8 is fixed on the frame 1 by the fixed bracket 10 through the fixing groove 9, it can only rotate and will not move. Thus, the adjusting screw rod 7 can move, enabling the first L-shaped fixing plate 13 rotatably installed at one end to move closer to the second support plate 3 and fixing the plate on it.

[0038] In one embodiment, for the above-mentioned first L-shaped fixing plate 13, a first sliding rail 14 is installed at one end of the first L-shaped fixing plate 13. The second support plate 3 includes a second L-shaped fixing plate 15. A second sliding rail 16 is installed at one end of the second L-shaped fixing plate 15. A sliding plate 17 is slidably installed in the first sliding rail 14 and the second sliding rail 16. The sliding plate 17 connects the first L-shaped fixing plate 13 and the second L-shaped fixing plate 15 to each other.

[0039] By installing a first sliding rail 14 at one end of the first L-shaped fixing plate 13 and a second sliding rail 16 at one end of the second L-shaped fixing plate 15, and installing a sliding plate 17 in the double sliding rails, the first L-shaped fixing plate 13 and the second L-shaped fixing plate 15 can be connected and cooperate with each other.

[0040] In one embodiment, for the above-mentioned second support plate 3, the second support plate 3 further includes a rotating column 18. The second L-shaped fixing plate 15 is installed on the rotating column 18. One end of the rotating column 18 penetrates through the inner wall of the frame 1 and extends to the outside. A notch 19 is formed in the outer end of the rotating column 18. An adjusting disc 20 is coaxially installed on the rotating column 18. The adjusting disc 20 can be slidably matched with the notch 19. A spring 21 is installed around the rotating column 18 on the outside of the adjusting disc 20. A spring fixing plate 22 is installed at the axis of the outer end of the rotating column 18. A plurality of holes 23 are evenly formed on one side of the frame 1 around the rotating column 18. A plug 24 is installed on one side of the adjusting disc 20. The plug 24 can be inserted into the holes 23 in a fitting manner.

[0041] By installing the adjusting disk 20 in the notch 19 on the rotating column 18, the second L-shaped fixing plate 15 installed at one end of the rotating column 18 can be driven to rotate when the adjusting disk 20 is rotated. Because the latch 24 installed on the adjusting disk 20 can fit with the multiple holes 23 uniformly opened around the rotating column 18 on one side of the frame 1, the adjusting disk 20 can be slid in the notch 19, and then the adjusting disk 20 is rotated to insert its latch 24 into the holes 23 at different angles, so that the angle direction of the plate fixed on the second L-shaped fixing plate 15 can be adjusted to achieve multi-angle adjustment and edge grinding. In addition, because the spring 21 can be compressed under the action of the spring fixing plate 22 when the adjusting disk 20 slides, when it is to be inserted into the hole 23, the elastic force is released, and it is quickly inserted into the hole 23, and the latch 24 will not be allowed to escape from the hole 23 by itself, so as to achieve the effect of continuous fixing.

[0042] The utility model can rotate the adjustment disk 20 to adjust the angle of the plate fixed on the first slide rail 14 and the second slide rail 16, so that the chamfering and grinding operation can be adjusted at multiple angles. After the plate rotates and the distance changes, the driving structure 4 can also drive the edge grinding structure 6 to contact it to achieve the grinding effect, and can grind the chamfered surface with a larger slope, so that the device can meet the chamfering and grinding needs of multiple requirements, can flexibly perform grinding work, improve work efficiency, and reduce its manual intervention.

[0043] In one embodiment, for the above-mentioned driving structure 4, the driving structure 4 includes a driving screw 25, and the driving screw 25 is rotatably installed on the inner walls on both sides of the frame 1. The thread directions of the two ends of the driving screw 25 are opposite. The two ends of the driving screw 25 are penetrated and threadedly installed with moving blocks 26, and the moving block 26 is penetrated and slidably installed with a positioning column 27. The two ends of the positioning column 27 are installed on both sides of the inner wall of the frame 1, and a telescopic folding frame 28 is rotatably installed on the moving block 26, and a connecting slider 29 is installed on the other end of the telescopic folding frame 28.

[0044] By rotating the driving screw 25, the movable blocks 26 at both ends can be moved toward the middle with the cooperation of the positioning column 27, so that the telescopic folding frame 28 can be extended or folded, thereby driving the fixed structure 5 to move through the connecting slider 29, so that the edge grinding structure 6 can chamfer and grind the edges and corners of the plate according to requirements.

[0045] In one embodiment, for the above-mentioned driving screw 25, one side of the driving screw 25 passes through the frame 1 and extends to the outside, a driving shaft 30 is axially installed at one end of the outside of the driving screw 25, and the axial center of the driving shaft 30 is installed on a driving motor 31. A motor fixing plate 32 is installed on the lower surface of the driving motor 31, and the motor fixing plate 32 is installed on the surface of one side of the frame 1.

[0046] A driving motor 31 is installed on the motor fixing plate 32, so that when the driving motor 31 is driven, it can drive the driving screw 25 to rotate through the driving shaft 30, so as to move the moving block 26 above it, making it automatic and being able to control the movement of the moving block 26 through the driving motor 31.

[0047] In one embodiment, for the above-mentioned fixed structure 5, the fixed structure 5 includes a movable plate 33, a movable slide rail 34 is installed on one side of the movable plate 33, the connecting slider 29 can slide in the movable slide rail 34, positioning slide rails 35 are installed on both sides of the inner wall of the frame 1, positioning sliders 36 are installed at both ends of the movable plate 33, the positioning sliders 36 can slide in the positioning slide rails 35, and a polishing fixed plate 37 is installed on the lower surface of the movable plate 33.

[0048] By installing a movable slide rail 34 on one side of the movable plate 33, and the connecting slider 29 can slide with it, when the telescopic folding frame 28 drives the connecting slider 29 to move, the connecting slider 29 can slide in the movable slide rail 34 and drive it to move, and the positioning slide rails 35 on both sides of the frame 1 can enable the positioning sliders 36 at both ends of the movable plate 33 to slide therein, so that when the movable plate 33 moves, it can slide on its positioning slide rail 35, increase its stability, and allow it to move in parallel, and the grinding fixed plate 37 can install its edge grinding structure 6 on it.

[0049] In one embodiment, for the above-mentioned edge grinding structure 6, the edge grinding structure 6 includes a grinding motor 38, which is installed on the grinding fixed plate 37. A grinding drive shaft 39 is installed on the axis of the grinding motor 38. The grinding drive shaft 39 passes through the movable plate 33 and extends to the upper part. A grinding drive column 40 is installed on the upper end of the grinding drive shaft 39. The edge grinding structure 6 also includes a rotating column 41, which is installed on the upper surface of the movable plate 33. A grinding belt 42 is movably mounted on the grinding drive column 40 and the rotating column 41.

[0050] By installing the grinding motor 38 on the grinding fixed plate 37, after driving the grinding motor 38, the grinding drive column 40 above the movable plate 33 is driven to rotate through the grinding drive shaft 39, so that with the cooperation of the rotating column 41, the grinding belt 42 on which it is movable can be rotated to grind the edges and corners of the plate, and the grinding belt 42 can be disassembled and replaced, thereby increasing the long-term use of the device.

[0051] In summary, by means of the above technical solution of the present utility model, the sheet material is placed on the first L-shaped fixing plate 13 and the second L-shaped fixing plate 15. Then, by rotating the rotating handle 12, the nut 8 is driven to rotate through the rotating plate 11. Since the nut 8 is fixed on the frame 1 by the fixing groove 9 and the fixing frame 10, it can only rotate and will not move. Thus, the adjusting screw rod 7 can move, causing the first L-shaped fixing plate 13 rotatably installed at one end to move closer to the second L-shaped fixing plate 15, and the sheet material can be fixed on it. A first slide rail 14 is installed at one end of the first L-shaped fixing plate 13, and a second slide rail 16 is installed at one end of the second L-shaped fixing plate 15. A sliding plate 17 is installed in the double slide rails, enabling the first L-shaped fixing plate 13 and the second L-shaped fixing plate 15 to be connected and cooperate with each other. Further, the adjusting disc 20 is installed in the notch 19 on the rotating column 18, so that when the adjusting disc 20 is rotated, the second L-shaped fixing plate 15 installed at one end of the rotating column 18 can be driven to rotate. Since the pin 24 installed on the adjusting disc 20 can fit with a plurality of holes 23 evenly opened on one side of the frame 1 around the rotating column 18, the adjusting disc 20 can be slid in the notch 19. Then, by rotating the adjusting disc 20 and inserting the pin 24 into the holes 23 at different angles, the angular direction of the sheet material fixed on the second L-shaped fixing plate 15 can be adjusted to achieve multi-angle edge grinding treatment. Because the spring 21 can be compressed under the action of the spring fixing plate 22 when the adjusting disc 20 slides, and when it is to be inserted into the hole 23, the elastic force is released and it can be quickly inserted into the hole 23 without the pin 24 coming out of the hole 23 by itself, achieving the function of continuous fixation. At this time, by driving the driving screw rod 25 to rotate through the driving motor 31, the moving blocks 26 installed at both ends can move closer to the middle under the cooperation of the positioning columns 27, driving the telescopic folding frame 28 to expand or fold, thereby driving the connecting slider 29 to slide in the moving slide rail 34 and driving it to move. The positioning slide rails 35 on both sides inside the frame 1 enable the positioning sliders 36 at both ends of the moving plate 33 to slide therein, so that when the moving plate 33 moves, it can slide in the positioning slide rails 35, increasing its stability and enabling it to move parallel. Also, by installing the grinding motor 38 on the grinding fixing plate 37, after driving the grinding motor 38, the grinding driving column 40 above the moving plate 33 is driven to rotate through the grinding driving shaft 39. Thus, under the cooperation of the rotating column 41, the grinding belt 42 sleeved thereon can rotate to perform grinding operations on the edges of the sheet material, and the grinding belt 42 can be disassembled and replaced, increasing the long-term usability of the device.

[0052] Through the above technical solutions: 1. The first support plate 2 can firmly fix the plates placed above, preventing them from loosening. The second support plate 3 can change the angle of the plates. Then, the driving structure 4 drives the edge grinding structure 6 to grind the edges of the plates, enabling flexible grinding, achieving multi-angle grinding of the plates, and grinding chamfers at different angles, eliminating the need for manual operation, improving work efficiency. Moreover, the device has a simple structure and low cost, and is better adapted for use in small factories. 2. By rotating the adjustment disk 20 of the present utility model, the plates fixed on the first slide rail 14 and the second slide rail 16 can be rotated to adjust the angle, achieving multi-angle chamfer grinding operations. After the plates rotate and the distance changes, the driving structure 4 can also drive the edge grinding structure 6 to contact it, achieving the grinding effect and being able to grind chamfer surfaces with larger inclined planes. Furthermore, the device of the present utility model can meet the multi-demand chamfer grinding, flexibly perform grinding work, and improve work efficiency while reducing manual intervention.
