Description

Technical Field

[0001] The present invention relates to the technical field of wood processing equipment, and more specifically, to a wood grinding device. Background Art

[0002] Wood is a general term for plant tissues developed inward from the vascular cambium, including xylem and thin-walled rays. Wood plays a great supporting role in human life. According to different property characteristics of wood, people use them in different ways. After the wood board is cut, it is necessary to grind the wood board to obtain a certain smoothness or texture to increase the beauty of the furniture. A wood grinding device is required. The wood grinding device is a device for grinding the edges and burrs on the wood board.

[0003] The Chinese patent discloses a furniture wood surface grinding device with the patent number CN202222386848.5. This furniture wood surface grinding device is adapted to limit and fix different thicknesses and heights of furniture wood through the adaptive limit of the limit sliding frame and the adjustment and adsorption of the suction cup, which improves the flexible adjustment and fixation of the furniture wood by the grinding device. However, there are still certain problems. The grinding device is provided with grinding components on both sides of the wood, so it can grind the wood on both sides. However, when the grinding device clamps the wood, the wood is placed in a U-shaped base, and then the suction cup is driven to clamp the wood by screwing the first bolt. Since the U-shaped base has a certain depth and the suction cup that abuts against the wood also has a certain width, the whole wood cannot be completely presented, resulting in that a part of the wood surface cannot be effectively ground, thus affecting the grinding effect and the quality of the finished product. Therefore, we provide a wood grinding device. Summary of the Invention

[0004] The purpose of the present invention is to provide a wood grinding device to solve the problems raised in the above background art:

[0005] When some existing wood grinding devices clamp the wood, the wood is placed in a U-shaped base, and then the suction cup is driven to clamp the wood by screwing the first bolt. Since the U-shaped base has a certain depth and the suction cup that abuts against the wood also has a certain width, the whole wood cannot be completely presented, resulting in that a part of the wood surface cannot be effectively ground, thus affecting the grinding effect and the quality of the finished product.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A wood grinding device, comprising a frame. An electric motor mounting bracket is fixedly connected to the outside of the frame. A stepping motor is fixedly connected to the outside of the electric motor mounting bracket. The output end of the stepping motor is fixedly connected to a flipping frame. A grinding mechanism is arranged above the flipping frame. A first groove is formed inside the flipping frame. An annular plate is arranged inside the first groove. The annular plate is fixedly connected to the frame. A second groove is formed inside the annular plate. The second groove consists of three parts, two upper and lower semi-circular grooves, one large and one small. The centers of these two semi-circular grooves coincide with the center of the annular plate and the center of the output shaft of the stepping motor. The other part of the second groove is an inclined groove connecting these two semi-circular grooves. When the first sliding rod enters the inclined groove, the first sliding rod will drive the movable plate to move under the extrusion of the inner wall of the inclined groove. When a first sliding rod is slidably connected inside the second groove, the other end of the first sliding rod is fixedly connected to a movable plate. A third groove is formed inside the movable plate on the side away from the first sliding rod. A second sliding rod is slidably connected inside the third groove. The other end of the second sliding rod is fixedly connected to a gear. The gear is rotatably connected to the flipping frame. Two racks are slidably connected inside the first groove. The two racks are point-symmetrically arranged about the center of the gear. When the gear rotates, the two racks move simultaneously, and one moves in and the other moves out alternately. The racks are meshed with the gear. A clamping mechanism is arranged outside the racks, and the clamping mechanism is used to clamp the wood.

[0008] Preferably, the flipping frame is of a U-shaped structure. The wood to be ground mainly enters and exits the flipping frame from the open side of the U-shaped flipping frame. Through the flipping frame, the clamped wood can be flipped 180 degrees, so that both sides of the wood can be ground.

[0009] Preferably, the clamping mechanism includes a supporting plate. The supporting plate is fixedly connected to the rack. A sliding groove is formed inside the supporting plate. A clamping plate is slidably connected inside the sliding groove. A threaded rod is threadedly connected inside the supporting plate. The threaded rod is rotatably connected to the clamping plate. A guiding rod is slidably connected inside the clamping plate. The guiding rod is fixedly connected to the supporting plate. The supporting plate mainly serves to support the wood to be ground. The wood is directly placed on the supporting plate, and the clamping plate can clamp the wood from both sides to prevent the wood from loosening when the grinding roller grinds the wood. The user can rotate the threaded rod, and the threaded rod can directly drive the clamping plate to move, so as to clamp woods of different widths.

[0010] Preferably, a limiting groove is formed inside the rack. A limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the flipping frame. The rack is limited by the limiting block and the limiting groove to ensure the normal meshing of the rack and the gear.

[0011] Preferably, a limiting rod is slidably connected inside the movable plate, and the limiting rod is fixedly connected to the flipping frame. The movable plate is limited by the limiting rod. There are two limiting rods on each movable plate, which are symmetrically distributed up and down, and the movable plate can move back and forth on the limiting rod.

[0012] Preferably, the grinding mechanism includes an electric push rod. The electric push rod is used to drive the lifting frame to move up and down, so as to adjust the height of the grinding roller. When the grinding roller rises to the highest position, it will not affect the flipping frame to drive the wood to flip, and at the same time, it is convenient for the grinding roller to grind woods of different thicknesses. The electric push rod is fixedly connected to the machine frame. The output end of the electric push rod is fixedly connected to a lifting frame. A first servo motor is fixedly connected to the outside of the lifting frame. The first servo motor drives the lead screw to rotate. The movable frame is driven to move back and forth through the lead screw, so as to adjust the position of the grinding roller. The output end of the first servo motor is fixedly connected to a lead screw. The lead screw is rotatably connected to the lifting frame. A movable frame is sleeved outside the lead screw. The movable frame is threadedly connected to the lead screw. A second servo motor is fixedly connected to the outside of the movable frame. The output end of the second servo motor is fixedly connected to a grinding roller. The grinding roller is rotatably connected to the movable frame. The wood is ground by driving the grinding roller to rotate through the second servo motor.

[0013] Preferably, the upper surface of the movable frame fits with the lower surface of the lifting frame, and the movable frame is slidably connected to the lifting frame. The upper surface of the movable frame fits tightly with the lower surface of the lifting frame, which can play a role in limiting the movable frame. When the first servo motor drives the lead screw to rotate, due to the limitation of the movable frame, the rotating lead screw can drive the movable frame to move back and forth, so as to control the position of the grinding roller on the movable frame, which is beneficial to driving the grinding roller to grind each position of the wood.

[0014] Preferably, a control panel is fixedly connected to the outside of the motor mounting frame. The stepping motor, the electric push rod, the first servo motor and the second servo motor are all electrically connected to the control panel. The stepping motor, the electric push rod, the first servo motor and the second servo motor in the device are all powered by an external power supply and controlled through the control panel.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) When this wood grinding device is in use, after one side of the wood is ground, the electric push rod is started to drive the grinding roller to move upward to a specified position. The stepping motor drives the wood to flip through the flipping frame. During this process, the first sliding rod is squeezed by the inclined groove on the second groove, which will drive the movable plate to move. The movable plate drives the gear to rotate through the third groove and the second sliding rod. At this time, the supporting plate and the clamping plate on the upper surface of the wood start to move away from the wood, while the supporting plate and the clamping plate on the lower surface of the wood start to approach the wood and begin to support and clamp the wood. When the wood is completely flipped 180 degrees, the wood is also clamped. The wood is supported by the supporting plate, and at the same time, it is clamped from both sides by the clamping plate, so that the entire surface of the wood can be completely presented, enabling the grinding roller to comprehensively grind the wood.

[0017] 2) When this wood grinding device is in use, by rotating the threaded rod, the clamping plate can be driven to move back and forth in the sliding groove, thereby adjusting the position of the clamping plate, which is beneficial for the clamping mechanism to clamp woods of different widths. By the electric push rod, the height of the grinding roller can be directly adjusted, and woods of different thicknesses can be ground, thus improving the overall adaptability of the device.

Subsequently, start the stepping motor 3 to rotate forward, and the stepping motor 3 drives the flipping frame 4 to rotate, so as to drive the wood to flip through the flipping frame 4. When the wood is about to flip to 180 degrees, the first slide bar 9 will be squeezed by the inclined groove on the second groove 8, so as to drive the movable plate 10 to move. The movable plate 10 squeezes the second slide bar 12 through the inner wall of the third groove 11, and drives the gear 13 to rotate by using the second slide bar 12. At this time, the supporting plate 1501 and the clamping plate 1503 on the upper surface of the wood start to move away from the wood, while the supporting plate 1501 and the clamping plate 1503 on the lower surface of the wood start to approach the wood and start to support and clamp the wood. When the wood is completely flipped 180 degrees, the wood is also clamped. If it is necessary to release the clamping of the wood, control the stepping motor 3 to rotate slightly in the reverse direction. After the wood is clamped, start the electric push rod 501 to drive the grinding roller 507 to move downward until the grinding roller 507 abuts against the wood, and then start the first servo motor 503 and the second servo motor 506 to drive the grinding roller 507 to grind the wood. The wood is supported by the supporting plate 1501, and at the same time, the clamping plate 1503 is used to clamp the wood from both sides, so that the entire surface of the wood can be presented completely, and the grinding roller 507 can comprehensively grind the wood.
