Description

Technical Field

[0001] The invention relates to the technical field of wood product processing, in particular to a surface grinding device and method for producing wood products. Background Art

[0002] Surface grinding is a crucial link in the production process of wooden products such as tables and chairs. It is directly related to the final appearance quality, comfort and durability of the product. With the development of the woodworking industry and the continuous improvement of consumers' quality requirements, the traditional manual grinding method has been difficult to meet the needs of large-scale, high-efficiency and high-quality production. There are many types of surface grinding devices on the market, but there are not many devices specifically for the production of wooden products such as tables and chairs. These devices may not meet the specific needs of table and chair manufacturers in terms of function, performance, adaptability, etc. Therefore, it is necessary to develop a surface grinding device specifically for the production of tables and chairs to meet the urgent needs of the industry.

[0003] For example, the patent application with the prior art announcement number CN215394404U relates to the field of bamboo and wood processing technology, and discloses a grinding device for processing bamboo and wood products, including a bottom plate, a grinding assembly is arranged on the top of the bottom plate, a placement assembly is arranged on the top of the bottom plate, and a fixing assembly extending to the top and movably connected to the grinding assembly is arranged between the left and right sides of the inner wall of the placement assembly. The grinding device for processing bamboo and wood products starts the servo motor to drive the right gear to rotate, and then the left gear to rotate to rotate the rotating shaft, the servo motor deflects the right push rod, the rotating shaft deflects the left push rod, so that the left and right push rods deflect toward each other, the push rod moves the push shaft inside the driving frame, and then the left and right push shafts drive the left and right drive frames to move toward each other, the drive frame drives the moving frame to move synchronously along the fixed plate, and the moving frame makes the support shaft and the clamping plate move synchronously, so as to achieve the purpose of fixing bamboo and wood of different sizes.

[0004] In the existing wood board processing technology, although the bamboo and wood materials of different sizes can be flexibly fixed by setting an adjustable clamping plate, this design plays a positive role in enhancing the processing flexibility and versatility. However, in the actual production and processing process, when the wood board is fed into the grinding equipment for surface grinding or trimming, a large amount of wood chips and debris will inevitably be generated. These wood chips and debris are light in material and small in size, and are easily affected by gravity and attached to the surface or edge of the wood board. Especially in continuous and high-speed grinding operations, the accumulation speed of debris will be faster. They will gradually accumulate and cover the surface of the board to form a barrier layer. This barrier layer will not only increase the friction resistance between the grinding tool and the board, reduce the grinding efficiency, but also may have an adverse effect on the grinding quality, such as increasing the surface roughness and decreasing the flatness. More seriously, under long-term working conditions, the accumulation of debris may also cause damage to the grinding equipment, such as blocking the chip discharge port and aggravating the wear of the equipment. For this reason, the present application proposes a surface grinding device and method for the production of wood products. Summary of the invention

[0015] The present invention also provides a surface grinding method for wood product production, comprising the following steps:

[0016] S1. When in use, the wooden board is first placed on the top surface of the workbench and between two clamping plates, and then the driving assembly is started to drive the clamping plates to move, thereby fixing the wooden board;

[0017] S2. When the splint fixes the wooden board, the wooden board will hit the trigger component, and the trigger component will inflate air into the air receiving cylinder, thereby driving the second piston rod to move downward and hit the surface of the wooden board;

[0018] S3, then turning on the grinder to rotate the grinding wheel to grind the wooden board on the workbench, and the driving assembly can be controlled to adjust the positions of the two clamping plates to change the position between the wooden board and the grinding wheel;

[0019] S4. Then, the air pump is turned on to deliver the gas to the air pipe nozzle. The driving component is continuously driven to provide power to the power component to drive the pull plate to pull the air pipe nozzle to swing, thereby changing the blowing angle of the air pipe nozzle.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the design of the trigger component, when the splint contacts the wooden board, it will automatically trigger the gas push mechanism in the gas cylinder, and then inflate the gas receiving cylinder through the auxiliary gas path, so that the reinforcement plate moves down and tightly contacts the surface of the wooden board. This adaptive clamping force adjustment not only ensures the stable clamping of the board, but also avoids damage to the board caused by excessive clamping force. The initial splint clamping and the subsequent downward pressure of the reinforcement plate form a double clamping, which greatly improves the stability of the board during processing and reduces the risk of board displacement caused by vibration or external force. The second screw and nut sleeve connected by thread, as well as the coordination of the tooth groove and the tooth plate, realize the precise adjustment of the distance between the two splints.

[0022] 2. Blowing air to the top of the wood board through the air pipe nozzle effectively blows away the debris generated during the grinding process, avoiding the impact of debris accumulation on processing quality and equipment performance. At the same time, the blowing also plays a cooling role, preventing the board from being deformed or damaged due to high temperature. The design of the power component enables the air pipe nozzle to swing, thereby expanding the coverage of the blowing, ensuring comprehensive cleaning and cooling of the board surface, and improving the cleaning efficiency. The design of the auxiliary air path cleverly distributes the gas output by the air pump to the reinforcement system and the blowing system, realizing the linkage of the two systems. When the air pump is working, it not only enhances the clamping force of the reinforcement plate on the board, but also drives the operation of the blowing system at the same time. Through the linkage of the ring gear, pinion and cam, the adaptive adjustment of the swing angle of the air pipe nozzle is realized. This adjustment is automatically carried out with the adjustment of the position of the splint, without manual intervention, which improves the convenience and efficiency of operation.

[0041] For further information, see Figure 4 , Figure 8 as well as Fig. 9In order to facilitate the adjustment of the positions of the two clamping plates 200 and the distance between the two clamping plates 200, the driving assembly includes two nut sleeves 204 threadedly connected to the outer surface of the second screw rod 201, the outer surfaces of the two nut sleeves 204 are fixedly connected with collars 400, and the outer surfaces of the two collars 400 are provided with a plurality of tooth grooves 401, one side of the two clamping plates 200 is fixedly connected with an auxiliary frame 416, the tops of the two auxiliary frames 416 are fixedly connected with a driving cylinder 403, and the output ends of the two driving cylinders 403 are provided with tooth plates 405 adapted to the plurality of tooth grooves 401, the tops of the two tooth plates 405 are provided with grooves, and the two grooves are slidably connected with the driving cylinders The lifting plate 404 is fixedly connected to the output end 403, and the two grooves are fixedly connected with displacement springs 406 for driving the lifting plate 404 to reset. The second screw rod 201 is threadedly connected to the nut sleeve 204 so that the nut sleeve 204 rotates with it, and the tooth plate 405 can adapt to the tooth groove 401 to limit the rotation of the ring 400. At this time, the second screw rod 201 is threadedly connected to the nut sleeve 204 so that the nut sleeve 204 is displaced to adjust the position of the splint 200. By setting the tooth groove 401 and the tooth plate 405 to cooperate, the nut sleeve 204 can be driven to move and the position of the splint 200 can be adjusted, so that the distance between the two splints 200 can be adjusted, and the two splints 200 can be driven to move synchronously.

[0042] For further information, see Figure 5 , Figure 6 as well as Fig.12 In order to further improve the clamping force of the plywood 200 on the wooden board, an air cylinder 211 is provided on the top of the two plywoods 200, and the bottom of the two air cylinders 211 is slidably connected with a second piston rod 212 adapted thereto, and the bottom of the two second piston rods 212 is fixedly connected with a reinforcing plate 213 for resisting the wooden material, and the inside of the plywood 200 is provided with a trigger component for inflating the inside of the air cylinder 211, and the trigger component includes two air cylinders 206 fixedly connected to one side of the plywood 200, and the inside of the two air cylinders 206 is slidably connected with a first piston rod 207 adapted thereto, and one end of the two first piston rods 207 is fixedly connected with a trigger plate 205, and the two The gas cylinders 206 are commonly connected with an air circuit 208, and the top of the air circuit 208 is connected with an auxiliary air circuit 209 connected with the gas receiving cylinder 211. The two gas cylinders 206 are fixedly connected with a spring 210 for driving the piston end of the first piston rod 207 to return to its original position. The outer surface of the second piston rod 212 is sleeved with a sleeve spring 214 for driving the second piston rod 212 to return to its original position. The trigger plate 205 is forced to drive the first piston rod 207 to approach the gas cylinder 206, so that the piston end of the first piston rod 207 pushes into the gas circuit 208, and the auxiliary air circuit 209 is poured into the gas receiving cylinder 211, thereby driving the piston end of the second piston rod 212 to move downward, and then driving the reinforcement plate 213 to move downward to squeeze the wooden board.

[0043] The top of the workbench 103 is fixedly connected with a mounting plate 108 , and a bellows guard plate 109 is fixedly connected between one side of the mounting plate 108 and the clamping plate 200 . The bellows guard plate 109 can prevent debris from entering the groove on the top surface of the workbench 103 .

[0044] Specifically, when in use, the wooden board is first placed on the top surface of the workbench 103 and between the two clamps 200, and then the second driving motor 202 is turned on to drive the second screw rod 201 to rotate. At the same time, the driving cylinder 403 is turned on to drive the lifting plate 404 to move downward and then drive the tooth plate 405 to move downward into the tooth groove 401 for limiting. At this time, because the ring 400 is fixed, the rotation of the second screw rod 201 will drive the nut sleeve 204 to move, thereby driving the clamp 200 to move, and then fix the wooden board. When the clamp 200 fixes the wooden board, the wooden board will contact the trigger plate 205 and then push the first piston rod 207 to slide in the air cylinder 206, so that the gas in the air cylinder 206 is pushed to the inside of the air path 208, and then transported to the air receiving cylinder 211 through the auxiliary air path 209, thereby driving the second piston rod 212 to move downward, thereby driving the reinforcement plate 213 to move downward and contact the surface of the wooden board.

[0045] In summary, through the design of the trigger component, when the splint 200 contacts the wooden board, it will automatically trigger the gas push mechanism in the gas cylinder 206, and then inflate the gas receiving cylinder 211 through the auxiliary gas path 209, so that the reinforcement plate 213 moves down and tightly contacts the surface of the wooden board. This adaptive clamping force adjustment not only ensures the stable clamping of the board, but also avoids damage to the board caused by excessive clamping force. The initial clamping of the splint 200 and the subsequent downward pressure of the reinforcement plate 213 form a double clamping, which greatly improves the stability of the board during processing and reduces the risk of board displacement caused by vibration or external force. The second screw 201 and the nut sleeve 204, as well as the tooth groove 401 and the tooth plate 405, are threadedly connected. The precise adjustment of the distance between the two splints 200 is achieved.

[0046] Example 2: Please refer to Figure 7 , Fig.10 as well as Fig.11The present invention also provides a technical solution, which is different from the technical solution of Example 1: a surface grinding device for the production of wooden products, the tops of the two plywood 200 are respectively fixedly connected with air pumps 300, the air outlet ends of the two air pumps 300 are connected with air pipe nozzles 306 rotatably connected to the plywood 200, and one side of the plywood 200 is provided with a power component for driving the air pipe nozzles 306 to swing, and the top of the wooden board can be blown by the air pipe nozzles 306 to blow away the debris after grinding, and at the same time it can be cooled, and the power component can drive the air pipe nozzles 306 to swing to increase its airflow coverage area.

[0047] For further information, see Fig. 9 , Fig.10 as well as Fig.11 One side of the auxiliary gas path 209 is connected to a side tube 301, one side of the side tube 301 is connected to a shunt tube 302, one end of the shunt tube 302 away from the side tube 301 is connected to a soft gas tube 305 connected to an air tube nozzle 306, the bottom of the air tube nozzle 306 is fixedly connected to a pull plate 415, the inside of the side tube 301 is slidably connected to a piston 303 adapted thereto, the bottom of the piston 303 is fixedly connected to a compression spring 304, and the bottom of the compression spring 304 is fixedly connected to the inside of the side tube 301, wherein the gas The gas in the pump 300 is firstly poured into the auxiliary gas circuit 209. At this time, the increase of gas in the auxiliary gas circuit 209 will increase the gas in the gas receiving cylinder 211, and the gas in the gas circuit 208 is poured into the gas delivery cylinder 206 to push the first piston rod 207 to move, thereby strengthening the fixing force of the trigger plate 205 and the reinforcement plate 213. At the same time, when the gas in the auxiliary gas circuit 209 increases, the compression piston 303 is moved downward and passes over the shunt tube 302, so that the gas is transported to the air pipe nozzle 306 through the shunt tube 302.

[0048] For further information, see Fig.10 , Fig.14 as well as Fig.15 In order to facilitate the driving of the air pipe nozzle 306 to swing, the power assembly includes a ring gear 402 fixedly connected to one side of the collar 400, a rotating shaft 407 is rotatably connected to the bottom of the auxiliary frame 416, one end of the rotating shaft 407 is fixedly connected to a small gear 408 meshing with the ring gear 402, and the other end of the rotating shaft 407 is fixedly connected to a cam 409, and the inside of the auxiliary frame 416 is slidably connected to a contact plate 410 whose bottom contacts the cam 409, and the top of the contact plate 410 is fixedly connected to a transmission plate 409. 13, and both sides of the transmission plate 413 are rotatably connected with cranks 414 rotatably connected to the pull plate 415. After the position of the clamping plate 200 is adjusted, the tooth plate 405 can be driven away from the tooth groove 401, so that the second screw rod 201 rotates and drives the nut sleeve 204 to rotate with it, so that the ring gear 402 drives the pinion 408 to rotate and drives the cam 409 to rotate, and continuously strikes the resistance plate 410 to move upward, thereby driving the crank 414 to tilt and driving the air pipe nozzle 306 to swing.

[0049] In order to reduce the resistance on the cam 409 , a bracket 411 is fixedly connected to the top of the auxiliary frame 416 , tension springs 412 are fixedly connected to both sides of the transmission plate 413 , and the bottom of the tension spring 412 is fixedly connected to the bracket 411 , and the bracket 411 can play a role in supporting the transmission plate 413 .

[0050] Specifically, by turning on the air pump 300, the gas is transported to the inside of the auxiliary air path 209. At this time, the internal gas of the auxiliary air path 209 gradually expands, so that the gas is transported to the inside of the side tube 301, thereby compressing the piston 303 to move downward, and then passing through the shunt pipe 302 so that the gas is transported to the inside of the air pipe nozzle 306 through the shunt pipe 302, and finally the gas is blown to the surface of the wooden board. At the same time, the driving cylinder 403 can be turned on to retract the lifting plate 404 and move it upward so that the tooth plate 405 is away from the ring 400, and then the second screw rod 201 is driven to rotate to make the nut sleeve 204 rotate with it. At this time, the ring 400 rotates to make the ring tooth 402 rotate to drive the pinion 408 to rotate and drive the rotating shaft 407 to rotate. Then the rotating shaft 407 rotates to drive the cam 409 to continuously push the resistance plate 410 to move upward, thereby driving the transmission plate 413 to move upward, thereby driving the crank 414 to tilt, thereby driving the pull plate 415 to pull the air pipe nozzle 306 to swing, thereby changing the blowing angle of the air pipe nozzle 306.

[0051] In summary, the top of the wooden board is blown by the air pipe nozzle 306, which effectively blows away the debris generated during the grinding process and avoids the influence of debris accumulation on the processing quality and equipment performance. At the same time, the blowing also plays a cooling role, preventing the board from being deformed or damaged due to high temperature. The design of the power component enables the air pipe nozzle 306 to swing, thereby expanding the coverage of the blowing, ensuring the comprehensive cleaning and cooling of the board surface, and improving the cleaning efficiency. The design of the auxiliary air path 209 cleverly distributes the gas output by the air pump 300 to the reinforcement system and the blowing system, realizing the linkage of the two systems. When the air pump is working, it not only enhances the clamping force of the reinforcement plate 213 on the board, but also drives the operation of the blowing system at the same time. Through the linkage of the ring gear 402, the pinion 408 and the cam 409, the adaptive adjustment of the swing angle of the air pipe nozzle 306 is realized. This adjustment is automatically carried out with the adjustment of the position of the clamping plate 200, without manual intervention, which improves the convenience and efficiency of operation.

[0052] Example 3: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a surface grinding method for wood product production, comprising the following steps:

[0053] S1. When in use, first place the wooden board on the top surface of the workbench 103 and between the two clamping plates 200, then turn on the second driving motor 202 to drive the second screw rod 201 to rotate, and at the same time turn on the driving cylinder 403 to drive the lifting plate 404 to move downward and drive the tooth plate 405 to move downward into the tooth groove 401 for limiting. At this time, because the ring 400 is fixed, the rotation of the second screw rod 201 will drive the nut sleeve 204 to move, thereby driving the clamping plate 200 to move, and then fix the wooden board;

[0054] S2. When the clamping plate 200 fixes the wooden board, the wooden board will contact the trigger plate 205, thereby pushing the first piston rod 207 to slide in the gas cylinder 206, so that the gas in the gas cylinder 206 is pushed into the inside of the gas path 208, and then transported to the gas receiving cylinder 211 through the auxiliary gas path 209, thereby driving the second piston rod 212 to move downward, thereby driving the reinforcement plate 213 to move downward to contact the surface of the wooden board;

[0055] S3, then start the grinder 101 to rotate the grinding wheel 102 to grind the wooden board on the workbench 103, and start the first drive motor 104 to drive the first screw rod 105 to rotate, thereby driving the nut seat 107 to move, thereby driving the workbench 103 to slide on the slide seat 106, thereby changing the lateral position between the wooden board and the grinding wheel 102, and at the same time start the second drive motor 202 to drive the second screw rod 201 to rotate, thereby adjusting the positions of the two clamping plates 200, and changing the longitudinal position between the wooden board and the grinding wheel 102;

[0056] S4, then start the air pump 300 to transport the gas to the inside of the auxiliary gas path 209. At this time, the internal gas of the auxiliary gas path 209 gradually expands, so that the gas is transported to the inside of the side tube 301, thereby compressing the piston 303 to move downward, and then passing through the shunt pipe 302 so that the gas is transported to the inside of the air pipe nozzle 306 through the shunt pipe 302, and finally the gas blows to the surface of the wooden board. At the same time, the driving cylinder 403 can be turned on to shrink the lifting plate 404 and move it upward so that the tooth plate 405 is away from the ring 400, and then drive the second screw rod 201 to rotate so that the nut sleeve 204 rotates with it. At this time, the ring 400 rotates to rotate the ring gear 402 to drive the pinion 408 to rotate and drive the rotating shaft 407 to rotate. Then the rotating shaft 407 rotates and drives the cam 409 to continuously push the resistance plate 410 to move upward, thereby driving the transmission plate 413 to move upward, thereby driving the crank 414 to tilt, thereby driving the pull plate 415 to pull the air pipe nozzle 306 to swing, thereby changing the blowing angle of the air pipe nozzle 306.
