Description

Technical Field

[0001] This invention relates to the field of furniture processing, specifically to a burr removal device for furniture processing boards and its usage method. Background Technology

[0002] In the furniture manufacturing process, the processing of boards is indispensable. In order to make the surface of the boards smoother and more beautiful after forming, and to facilitate the next processing step, the edges of the boards are usually deburred. This requires the use of a board deburring device.

[0003] When cutting boards into smaller pieces of a specified size, burrs often appear at the cut edges. The traditional method involves fixing the boards in place and then manually sanding them with sandpaper or using a handheld sander with a rotating sanding disc. This is cumbersome and inconvenient, as it makes it difficult to sand the cut edges on both sides of the board simultaneously, resulting in low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a burr removal device for furniture processing boards and its usage method, to solve the problems in the background art where grinding the cut edges of boards using a rotating grinding disc is cumbersome and inconvenient to simultaneously grind the cut edges on both sides of the board, resulting in low efficiency. To achieve the above objective, this invention provides the following technical solution: A burr removal device for furniture processing boards includes a storage box, a connecting frame fixedly connected to the right side of the storage box, a clamping and conveying mechanism fixedly connected to the inner side of the connecting frame, four grinding mechanisms arranged inside the clamping and conveying mechanism, and pushing mechanisms engaged at both ends of the clamping and conveying mechanism, with two pushing mechanisms respectively disposed in through slots opened on the front and rear sides of the storage box.

[0005] Preferably, the clamping and conveying mechanism includes a fixed plate and two sliding frames. The fixed plate is fixed to the inner side of the connecting frame. A motor is fixedly connected to the bottom surface of the fixed plate. A protrusion push disk is fixedly installed at the bottom end of the motor rotating shaft. A sliding push rod is sleeved on the protrusion on the lower end surface of the protrusion push disk. The sliding push rod is T-shaped.

[0006] The sliding frame is slidably connected to the inner side of the connecting frame. The left side of the right sliding frame is fixedly connected to one end of the sliding push rod. The bottom surfaces of both sliding frames are fixedly connected to a first toothed plate. The length of the first toothed plate on the left sliding frame is half the length of the first toothed plate on the right sliding frame. The side of the first toothed plate is movably fitted with a limiting block, and the limiting block is fixed on the bottom surface of the storage box. A transmission gear meshes between the two first toothed plates, and the transmission gear is rotatably connected to the bottom surface of the storage box.

[0007] The sliding frame has storage slots on both the front and rear sides of its inner wall. A filter box is installed on the bottom of the sliding frame, and the feed inlet of the filter box is connected to the storage slots. The sliding frame has grooves on both the upper and lower sides of its inner wall. Rotating rods are rotatably connected to the front and rear sides of the inner wall of the grooves. One-way bearings are fixedly sleeved at both ends of the side of the rotating rods. Hollow pressure rollers are fixedly sleeved on the outer ring of the one-way bearings. Multiple wear-resistant rubber blocks are alternately arranged on the side of the hollow pressure rollers.

[0008] Preferably, the grinding mechanism includes a grinding rod, a fixed bearing is fixedly sleeved on the side of the grinding rod, the outer side of the fixed bearing is fixed to the inner wall of the receiving groove, a driven bevel gear is fixedly sleeved on the side of the grinding rod, a driving bevel gear meshes with the side of the driven bevel gear, the driving bevel gear is fixedly sleeved on the side of the hollow pressure roller, and a grinding block is fixedly connected to the bottom of the driven bevel gear, and the grinding block is fixedly sleeved on the grinding rod.

[0009] A fan blade is fixedly sleeved on the bottom side of the grinding block, and a conical tube is fixedly sleeved on the side of the fan blade, with the conical tube located directly above the filter box.

[0010] Preferably, the grinding block is cylindrical, with spiral grinding wires provided on the sides of the two grinding blocks on the right, and grinding protrusions provided on the sides of the two grinding blocks on the left. The front and rear sides of the sliding frame on the left are fixedly connected with second toothed plates, and the two second toothed plates are on the outside of the two grinding blocks on the left.

[0011] Preferably, the pushing mechanism includes a cylindrical rod, the upper and lower ends of which are rotatably connected to the upper and lower sides of the inner wall of the through groove, and a rotating gear is fixedly sleeved on the middle of the side of the cylindrical rod, and the rotating gear meshes with the second toothed plate.

[0012] Hollow rings and torsion springs are movably sleeved at both ends of the side of the cylindrical rod, and the two ends of the torsion springs are fixedly connected to the end face of the hollow rings and the side of the cylindrical rod, respectively.

[0013] The two hollow rings have opposite ends that abut against the upper and lower sides of the inner wall of the through groove, respectively. A rectangular groove is provided on the side of the hollow ring. A telescopic plate is rotatably connected to the inner wall of the hollow ring. One end of the telescopic plate is hinged to the side of the cylindrical rod, and the other end of the telescopic plate is inserted into the rectangular groove.

[0014] Preferably, a rubber block is adhered to the end of the telescopic plate away from the cylindrical rod.

[0015] Preferably, the sliding push rod consists of an annular elliptical ring and a crossbar, and a limiting sleeve is movably sleeved on the side of the sliding push rod, and the limiting sleeve is fixed to the fixing plate.

[0016] Preferably, the method of using the furniture processing board burr removal device includes the following steps:

[0017] S1: When using this device to grind and deburr the cut edges of the cut sheet, the user first places the sheet neatly in the storage box, and then the motor drives the convex push disk to rotate continuously, causing the convex push sliding push rod on the convex push disk to move back and forth, pushing the right sliding frame to move back and forth, so that the first toothed plate on the right sliding frame drives the transmission gear to rotate, and in conjunction with the first toothed plate on the left sliding frame, drives the left sliding frame and the right sliding frame to move simultaneously relative to each other or in opposite directions.

[0018] S2: When the left sliding frame moves to the left, it drives the second toothed plate to move to the left simultaneously. At this time, the rotating gear rotates and drives the cylindrical rod to rotate, causing the rubber block on the telescopic plate to deflect and extend out of the hollow ring through the rectangular groove to abut against the plate that needs to be polished. As the rotating gear continues to drive the cylindrical rod to rotate, the rubber block rotates and pushes the bottom plate in the storage box to the right and moves into the interior of the left sliding frame. At this time, the two hollow pressure rollers in the left sliding frame roll on the upper and lower sides of the plate. When the upper hollow pressure roller rotates to the left, it works with the active bevel gear to drive the polishing block and fan blade on the driven bevel gear to rotate simultaneously. The polishing protrusions perform rough polishing on the front and back sides of the plate. The fan blades rotate counterclockwise and exhaust air downwards. When the polishing protrusions perform rough polishing on the front and back sides of the plate, the airflow is discharged into the filter box through the collection groove, reducing dust generation.

[0019] S3: When the left sliding frame moves to the right, the second toothed plate moves to the right, causing the cylindrical rod to rotate, which causes the telescopic plate to deflect and retract into the hollow ring, releasing the resistance on both sides of the plate and preventing the rubber block from pushing the plate to the left when the right sliding frame moves to the right. When the left sliding frame moves to the right, the hollow pressure roller does not rotate under the action of the one-way bearing inside, thus pushing the plate in the left sliding frame to the right. When the left sliding frame moves to the right, the right sliding frame moves to the left synchronously under the action of the first toothed plate and the transmission gear, pushing the plate in the left sliding frame into the right sliding frame. Similarly, at this time, the spiral grinding wire on the grinding block in the right sliding frame rotates to perform secondary grinding on the areas on the front and back sides of the plate after rough grinding, increasing the grinding quality of the plate cut. This process is repeated, and the device continuously conveys the un-grinded plate to the right through the hollow ring.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In this invention, when the left sliding frame moves to the left, it drives the second toothed plate to move to the left simultaneously. At this time, the rotating gear rotates and drives the cylindrical rod to rotate, causing the rubber block on the telescopic plate to deflect and extend out of the hollow ring through the rectangular groove to abut against the plate that needs to be polished. As the rotating gear continues to drive the cylindrical rod to rotate, the rubber block rotates and pushes the bottom plate in the storage box to the right and moves into the inside of the left sliding frame, ensuring that the device continuously feeds unpolished plates, which facilitates automatic feeding.

[0022] In this invention, two hollow pressure rollers inside the left sliding frame roll on the upper and lower sides of the plate. When the upper hollow pressure roller rotates to the left, it works in conjunction with the active bevel gear to drive the grinding block and fan blade on the driven bevel gear to rotate simultaneously. The grinding protrusions perform rough grinding on the front and back sides of the plate, and the fan blades rotate counterclockwise to exhaust air downwards. This causes the airflow to be discharged into the filter box from the collection groove when the grinding protrusions perform rough grinding on the front and back sides of the plate, thereby reducing dust generation.

[0023] In this invention, when the left sliding frame moves to the right, the hollow pressure roller does not rotate under the action of the one-way bearing inside, thus pushing the plate in the left sliding frame to the right. When the left sliding frame moves to the right, the right sliding frame moves to the left synchronously under the action of the first toothed plate and the transmission gear, pushing the plate in the left sliding frame into the right sliding frame. Similarly, at this time, the spiral grinding wire on the grinding block in the right sliding frame rotates to perform secondary grinding on the areas on the front and back sides of the plate after rough grinding, increasing the quality of grinding the plate cut.

[0045] The method of use and advantages of the present invention: The working process of the burr removal device for furniture processing is as follows:

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown:

[0047] S1: When using this device to grind and deburr the cut edges of the cut sheet, the user first places the sheet neatly in the storage box 1, and then the motor 32 drives the convex push disk 33 to rotate continuously, causing the convex push sliding push rod 34 on the convex push disk 33 to move back and forth left and right, pushing the right sliding frame 35 to move back and forth left and right, so that the first toothed plate 36 on the right sliding frame 35 drives the transmission gear 316 to rotate, and in conjunction with the first toothed plate 36 on the left sliding frame 35, drives the left sliding frame 35 and the right sliding frame 35 to move simultaneously relative to each other or in opposite directions;

[0048] S2: When the left sliding frame 35 moves to the left, it drives the second toothed plate 49 to move to the left simultaneously. At this time, the rotating gear 52 rotates, driving the cylindrical rod 51 to rotate, causing the rubber block 57 on the telescopic plate 55 to deflect. It extends out from the hollow ring 53 through the rectangular groove 54 and abuts against the plate that needs to be polished. As the rotating gear 52 continues to drive the cylindrical rod 51 to rotate, the rubber block 57 rotates and pushes the bottom plate in the storage box 1 to the right and moves into the left sliding frame 35. At this time, the left sliding frame 3... The two hollow pressure rollers 310 inside 5 roll on the upper and lower sides of the plate. When the upper hollow pressure roller 310 rotates to the left, it works with the active bevel gear 44 to drive the grinding block 43 and the fan blade 45 on the driven bevel gear 410 to rotate simultaneously. The grinding protrusion 48 performs rough grinding on the front and rear sides of the plate. The fan blade 45 rotates counterclockwise to exhaust air downwards. When the grinding protrusion 48 performs rough grinding on the front and rear sides of the plate, the airflow is discharged into the filter box 313 through the collection groove 312, reducing dust generation.

[0049] S3: When the left sliding frame 35 moves to the right, the second toothed plate 49 moves to the right, causing the cylindrical rod 51 to rotate, which causes the telescopic plate 55 to deflect and retract into the hollow ring 53, releasing the resistance on both sides of the plate and preventing the rubber block 57 from pushing the plate to the left when the right sliding frame 35 moves to the right. When the left sliding frame 35 moves to the right, the hollow pressure roller 310 does not rotate under the action of the one-way bearing 39 inside, thus pushing the plate in the left sliding frame 35 to the right. When the left sliding frame 35 moves to the right, the right sliding frame 35 moves to the left synchronously under the action of the first toothed plate 36 and the transmission gear 316, pushing the plate in the left sliding frame 35 into the right sliding frame 35. Similarly, at this time, the spiral grinding wire 47 on the grinding block 43 in the right sliding frame 35 rotates to perform secondary grinding on the areas on the front and back sides of the plate after rough grinding, increasing the quality of grinding at the cut of the plate. This process is repeated, and the device continuously conveys the un-grinded plate to the right through the hollow ring 53.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

S3: When the left sliding frame (35) moves to the right, the second toothed plate (49) moves to the right, causing the cylindrical rod (51) to rotate, causing the telescopic plate (55) to deflect and retract into the hollow ring (53), releasing the resistance on both sides of the plate, and preventing the rubber block (57) from pushing the plate to the left when the right sliding frame (35) moves to the right. When the left sliding frame (35) moves to the right, the hollow pressure roller (310) does not rotate under the action of the one-way bearing (39) inside, thus pushing the plate in the left sliding frame (35) to the right. (35) When moving to the right, the right sliding frame (35) moves to the left synchronously under the action of the first toothed plate (36) and the transmission gear (316), pushing the plate in the left sliding frame (35) into the right sliding frame (35). Similarly, at this time, the spiral grinding wire (47) on the grinding block (43) in the right sliding frame (35) rotates to perform secondary grinding on the area after rough grinding on the front and back sides of the plate, increasing the quality of grinding at the plate cut. This process is repeated, and the device continuously conveys the un-grinded plate to the right through the hollow ring (53).
