Technical Field
[0001] This utility model relates to the field of furniture production technology, specifically to a furniture production hole-opening and sanding device. Background Technology
[0002] Furniture is an essential household item for people to maintain normal life, engage in production practices and carry out social activities. Furniture occupies an increasingly larger proportion of people's lives. The production process of furniture requires many steps, one of the important steps being drilling holes in the surface of the board.
[0003] Publication No. CN218083184U discloses a drilling device for wood panels used in furniture production. This device adjusts the position of the drill rod left and right by controlling a first slider to slide left and right along a first slide block. It also includes a second slider and a second slide block; controlling the second slider to slide back and forth along the second slide block adjusts the position of the drill rod forward and backward. A second support plate and a second electric telescopic rod are also included; controlling the extension and retraction of the second electric telescopic rod moves the drill rod up and down, thus achieving the purpose of drilling holes in wood panels of different thicknesses. However, this patent still has the following problems in practical use:
[0004] The device adjusts the position of the drill rod left and right by sliding the first slider along the first slide block, and adjusts the position of the drill rod forward and backward by sliding the second slider along the second slide block. Controlling the extension and retraction of the second electric telescopic rod moves the drill rod up and down, thus achieving the purpose of drilling holes in boards of different thicknesses. In furniture production, burrs often form on the edges after drilling, affecting aesthetics and potentially scratching users. Since this device lacks a sanding function, workers need to transfer the drilled boards to sanding equipment, significantly reducing furniture board production efficiency and causing inconvenience.
[0005] A furniture manufacturing hole-opening and sanding device is proposed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a drilling and sanding device for furniture production, which solves the problem mentioned in the background art. Currently, the drill rod can be adjusted left and right by sliding the first slider along the first slide block, and the drill rod can be adjusted forward and backward by sliding the second slider along the second slide block. The second electric telescopic rod can be extended and retracted to move the drill rod up and down, thereby achieving the purpose of drilling holes in boards of different thicknesses. In the furniture production process, after drilling holes in the boards, burrs often appear on the edges. These burrs not only affect the appearance but may also scratch users during use. The current device does not have a sanding function, which means that workers need to transfer the drilled boards to sanding equipment for sanding, thus greatly reducing the production efficiency of furniture boards.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a furniture production hole-opening and sanding device, including a workbench, a support is provided on one side of the top of the workbench, a sliding mechanism is provided on one side of the top of the support, and an electric telescopic rod is provided at the bottom of the sliding mechanism; an adjustment mechanism is provided at the bottom of the electric telescopic rod, and a cleaning component is provided on the inner side of the bottom of the support.

A movable rod is rotatably connected to the front of the movable block, and a push plate is rotatably connected between the bottom ends of the movable rod. A rubber plate is detachably connected to the bottom of the push plate.
[0010] Preferably, the cleaning component includes a bellows fixedly installed on one side of the bottom of the bracket, with a duct fixedly connected inside one side of the bellows. One end of the duct passes through the bracket and is fixedly connected to it. A tapered tube is installed at the end of the duct away from the bellows.

A drive rod is rotatably connected between the top of the bellows and the fixed box. A third motor is fixedly installed at the top of the drive rod. A first rotating tooth is fixedly connected to the bottom of the drive rod. A second rotating tooth is installed at the end of the rotating shaft near the fixed box. A fixed frame is inserted into the inner side of the top of the bellows. A filter screen is embedded inside one side of the fixed frame.
[0011] Preferably, the limiting box has symmetrical limiting grooves on both sides inside, and a fixing block is installed on the side of the toothed plate away from the gear. A limiting rod is fixedly installed inside the fixing block, and the two ends of the limiting rod are slidably connected inside the limiting groove.
[0012] Preferably, the teeth on one side of the tooth plate are meshed with the gear.
[0013] Preferably, the first rotating tooth and the second rotating tooth are meshed together.
[0014] Preferably, the output rod of the second motor passes through the chassis and is rotatably connected to the chassis.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A furniture production drilling and polishing device is described below: The operator starts the first motor to drive the drill rod to drill holes in the board. At this time, the operator rotates the adjustment frame outside the rotating rod. The polishing disc and drill rod rotate 90 degrees counterclockwise around the rotating rod, aligning the polishing disc with the hole opening on the board surface. The operator then pulls the U-shaped rod to slide it inside the limiting box. The U-shaped rod drives the toothed plate to slide inside the limiting box. At this time, the first contraction springs on both sides of the U-shaped rod contract. Through the restoring property of the first contraction springs, the teeth on the toothed plate mesh with the gears, fixing the angle of the adjustment frame. Then, the second motor drives the polishing disc to rotate, polishing the burrs on the board surface. This achieves rapid adjustment of the drilling and polishing efficiency. This significantly expands the device's application range, reduces the steps workers take in processing furniture boards, improves processing efficiency, and provides convenience for workers. Workers insert the fixed frame into the top of the bellows, then activate the third motor to rotate the drive rod. The rotation of the first rotating gear drives the rotation of the second rotating gear, and the rotation of the shaft drives multiple sets of fan blades to rotate inside the duct. This allows external air to enter the bellows through the conical tube and duct. The filter screen then filters the wood dust in the air, achieving rapid filtration and collection of debris generated during board processing. This effectively reduces the amount of dust and debris in the air, providing a better working environment for workers. Furthermore, the detachable fixed frame design facilitates the collection and processing of accumulated debris inside the frame.
[0016] 1. The operator starts the electric telescopic rod to bring the drill rod close to the board. Then, the operator starts the first motor to drive the drill rod to drill a hole in the board. At this time, the operator rotates the adjustment frame outside the rotating rod. The grinding disc and drill rod rotate 90 degrees counterclockwise around the rotating rod, aligning the grinding disc with the hole on the board surface. The rotation of the adjustment frame causes the limit box to rotate. The operator pulls the U-shaped rod to slide inside the limit box. The U-shaped rod causes the toothed plate to slide inside the limit box. At this time, the first contraction springs on both sides of the U-shaped rod contract. The operator then releases the U-shaped rod, and the return property of the first contraction springs allows the teeth on the toothed plate to mesh with the gears. The angle of the adjustment frame is now fixed. The operator then starts the electric telescopic rod to bring the grinding disc into contact with the board surface. The operator then starts the second motor to rotate the grinding disc, using the grinding disc to drill a hole in the board. Surface burrs are removed, enabling rapid adjustment of drilling and grinding effects on the board material. This significantly expands the device's application range, reduces processing steps for furniture boards, increases processing efficiency, and provides convenience for users. When the drill rod or grinding disc approaches the board, the rubber plate first contacts the board surface. As the drill rod and grinding disc move downwards, two sets of movable rods rotate between the push plate and the moving block. The rotation of the movable rods pushes the moving block to slide outside the support rod. At this point, the two sets of moving blocks move outwards in opposite directions. The second contraction spring contracts, and the tension generated by the second contraction spring causes the rubber plate to continuously press downwards on the board, achieving a rapid fixation and limiting effect on the board. This effectively prevents the board from shifting during subsequent drilling or grinding, ensuring the accuracy of furniture board processing and providing practicality for users.
[0017] 2. The worker inserts the fixing frame into the top of the bellows and secures it with bolts. Then, the worker starts the third motor, which drives the drive rod to rotate. The rotation of the drive rod drives the first rotating gear, which in turn drives the second rotating gear, which in turn drives the rotating shaft. The rotating shaft then drives multiple sets of fan blades to rotate inside the duct. This creates negative pressure inside the duct, forcing outside air into the bellows through the conical tube and ductwork. The filter screen then filters the wood dust from the air, and the air is finally discharged through an outlet on one side of the bellows. This process quickly filters and collects the wood chips generated during board processing, effectively reducing the amount of dust and debris in the air and providing a better working environment for the workers. The detachable fixing frame design also facilitates the collection and disposal of accumulated wood chips inside the frame, making it convenient for workers to use. Attached Figure Description

[0032] Working principle: Before using this furniture production drilling and sanding device, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 8 As shown, the operator activates the electric telescopic rod 103 to bring the drill rod 206 closer to the board. Then, the operator activates the first motor 205 to drive the drill rod 206 to drill a hole in the board. At this time, the operator rotates the adjusting frame 201 outside the rotating rod 204. The grinding disc 210 and the drill rod 206 rotate 90 degrees counterclockwise around the rotating rod 204. At this time, the grinding disc 210 corresponds to the opening on the surface of the board. The rotation of the adjusting frame 201 drives the rotation of the limiting box 212. The operator pulls the U-shaped rod 213 to slide inside the limiting box 212. At this time, the U-shaped rod 213 drives the teeth... The toothed plate 215 slides inside the limiting box 212. At this time, the first contraction springs 214 on the outer sides of both ends of the U-shaped rod 213 contract. Then, the operator releases the U-shaped rod 213, and through the restoring property of the first contraction springs 214, the teeth on the surface of the toothed plate 215 can mesh with the gear 211. At this time, the angle of the adjusting frame 201 is fixed. Then, the operator starts the electric retraction rod 207 to drive the grinding disc 210 to fit against the surface of the board. At this time, the operator starts the second motor 209 to drive the grinding disc 210 to rotate, and uses the grinding disc 210 to grind the burrs on the surface of the board, thereby achieving... The device allows for rapid adjustment of drilling and sanding effects on the board material, significantly expanding its application range, reducing processing steps for furniture boards, increasing processing efficiency, and providing convenience for users. When the drill rod 206 or sanding disc 210 approaches the board material, the rubber plate 223 first contacts the board surface. As the drill rod 206 and sanding disc 210 move downwards, the two sets of movable rods 221 rotate between the push plate 222 and the moving block 219. The rotation of the movable rods 221 pushes the moving block 219 to slide outside the support rod 218. At this time, the two sets of moving blocks 219 face away from each other. When the material moves outward, the second contraction spring 220 contracts. The tension generated by the second contraction spring 220 causes the rubber plate 223 to continuously press down on the board, thereby achieving the effect of quickly fixing and limiting the board. This effectively prevents the board from shifting during subsequent drilling or sanding, ensuring the accuracy of furniture board processing and providing practicality for workers. The movement of the toothed plate 215 drives the movement of the fixing block 225. The movement of the fixing block 225 causes the limiting rod 226 to slide between the limiting grooves 224, making the movement of the toothed plate 215 more stable.
[0033] The worker inserts the fixing frame 311 into the top of the bellows 301 and secures it with bolts. Then, the worker starts the third motor 308, which drives the drive rod 307 to rotate. The rotation of the drive rod 307 drives the first rotating gear 309, which in turn drives the second rotating gear 310. The rotation of the second rotating gear 310 drives the rotating shaft 305, which in turn drives multiple sets of fan blades 306 to rotate inside the duct 302. This creates a negative pressure inside the duct 302, thereby allowing external air to... The air enters the interior of the air box 301 through the conical tube 303 and the duct 302. At this time, the filter screen 312 filters the wood dust in the air. Finally, the air is discharged through the outlet on one side of the air box 301, which can quickly filter and collect the debris generated during board processing. This can effectively reduce the phenomenon of debris and dust spreading in the air, thus providing a good working environment for the staff. In addition, the design of the detachable fixing frame 311 makes it easy for the staff to collect and process the debris accumulated inside the fixing frame 311, bringing convenience to the staff during use.
