[0002] Wood structure is a structure that is made of wood alone or mainly bears the load. It is connected and fixed by various metal connectors or mortise and tenon joints. It is used in many fields of furniture and construction. Since wood accounts for a large proportion of wood structure, in the process of producing wood structure products, it is necessary to grind the wood for producing wood structure to remove burrs and defects on the wood surface and make the wood surface smooth, so that the produced wood structure products will be more beautiful. The patent document with publication number "CN118163001A" discloses "a wooden board grinding device, comprising a conveyor, a first support plate, two second support plates, a plurality of grinding mechanisms, a first drive mechanism, a second drive mechanism, a first limit assembly and a second limit assembly. Thus, the simultaneous grinding of both sides of a plurality of wooden boards is achieved, which greatly improves the grinding efficiency. Meanwhile, only one adjustment is required for wooden boards with different spacings, which can simultaneously meet the requirements of grinding spacing and limit spacing, thereby improving the convenience and flexibility of operation." Although "the simultaneous grinding of both sides of a plurality of wooden boards is achieved, which greatly improves the grinding efficiency. Meanwhile, only one adjustment is required for wooden boards with different spacings, which can simultaneously meet the requirements of grinding spacing and limit spacing, thereby improving the convenience and flexibility of operation," the above-mentioned grinding device cannot promptly remove the wood chips generated by grinding when grinding the wooden structure.

The wood chips formed during the grinding process and the wood chips after cleaning fall into the collecting mechanism 5 and are collected to avoid the wood chips from scattering and making it difficult to clean. At the same time, the air entering the bed 1 is filtered by the anti-blocking mechanism 3 to remove the wood chips floating in the air, so as to prevent the wood chips from following the flow of air flow and causing internal blockage of the bed 1.

[0030] The cleaning mechanism 6 also includes two limit rods 605, which are slidably connected to the adapter sleeve 603.

[0034] Please refer to Figure 1 and Figure 7 The grinding mechanism 4 includes two coarse grinding rollers 401 and fine grinding rollers 402 arranged in parallel with each other, sprockets 403 are fixedly installed on the outer rings of the shafts of the coarse grinding rollers 401 and the fine grinding rollers 402 near the rear ends, a chain 404 is interlocked between the two sprockets 403, a servo motor 405 is connected to the rear end of the shaft of the coarse grinding roller 401, the shafts of the coarse grinding rollers 401 and the fine grinding rollers 402 are movably connected to the bed 1 through bearings, and the housing of the servo motor 405 is fixedly connected to the bed 1.

[0035] Specifically, after the servo motor 405 is started, it drives the sprocket 403 and the coarse grinding roller 401 to rotate, and then cooperates with the chain 404 and another sprocket 403 to drive the fine grinding roller 402 to rotate. The wooden structure is polished by the rotating coarse grinding roller 401 and the fine grinding roller 402, which facilitates the completion of the coarse grinding and fine grinding processes in sequence, thereby improving the grinding efficiency.

[0036] Please refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 Two cleaning brushes 608 are respectively located at the bottom of the coarse grinding roller 401 and the fine grinding roller 402, and their top surfaces are arc-shaped surfaces. Another cleaning brush 608 is located between the coarse grinding roller 401 and the fine grinding roller 402, and its top surface is a plane.

[0037] Specifically, while the coarse grinding roller 401 and the fine grinding roller 402 are grinding the wooden structure, some wood chips adhere to the surface of the coarse grinding roller 401, the fine grinding roller 402 and the wooden structure. While the coarse grinding roller 401 and the fine grinding roller 402 are rotating and the wooden structure is moving, the attached wood chips are cleaned by the cleaning brush 608.

[0038] Please refer to Figure 1 Two negative pressure fans 9 are installed on one side of the bed 1 near the top, and a filtering mechanism 10 is installed on the front side of the bed 1 near the top.

[0039] Specifically, after the negative pressure fan 9 is started, negative pressure is formed inside the bed 1, and wood chips and dust formed during the polishing of the wooden structure are sucked into the inside of the bed 1 and filtered by the filter mechanism 10 while the air flow flows, thereby preventing the wood chips and dust from diffusing into the surrounding air and polluting the surrounding environment.

[0040] Please refer to Figure 1 , Figure 3 and Figure 8 The anti-blocking mechanism 3 includes a carrying shaft frame 301, the outer ring of the carrying shaft frame 301 is fixedly connected to a net tube 302, a scraper strip 303 is arranged at the bottom of the net tube 302, the top surface of the scraper strip 303 is an arc-shaped surface, the top surface of the scraper strip 303 is in contact with the bottom surface of the net tube 302, and the carrying shaft frame 301 is movably connected to the bed 1, the scraper strip 303 is clamped to the bed 1, and the collecting mechanism 5 also includes a partition plate 505 fixedly connected to the top end between the inner walls of the front and rear ends of the collecting box 501, and the partition plate 505 is located at the bottom of the scraper strip 303.

[0041] Specifically, after negative pressure is formed inside the bed 1, wood chips and dust formed by grinding are sucked into the inside of the bed 1 along with the air. When the airflow flows through the mesh cylinder 302, larger wood chips and dust are intercepted by the mesh cylinder 302 to avoid clogging of the filter mechanism 10. When the wooden structure moves, the mesh cylinder 302 rolls due to the friction between the wooden structure and the mesh cylinder 302. During the rolling process, the scraper 303 scrapes off the wood chips and dust attached to the surface of the mesh cylinder 302 to avoid clogging caused by excessive attached wood chips and dust, so as to facilitate the recycling of the mesh cylinder 302. At the same time, a partition 505 is set inside the collection box 501 to block the airflow to prevent wood chips and dust from following the airflow to flow from the bottom of the scraper 303 to the filter mechanism 10.

[0042] Please refer to Figure 1 and Fig. 9The pressure mechanism 8 includes a carrying block 801, and cylinders 802 are installed on both sides of the bottom of the carrying block 801. Three pressure rollers 803 are movably installed at the front end of the carrying block 801.

[0043] Specifically, after the cylinder 802 is started, the carrying block 801 is driven to rise and fall, and then the pressing roller 803 is driven to rise and fall, so as to limit the wooden structures of different heights and press the wooden structures against the top of the grinding mechanism 4, so as to complete the grinding of the wooden structures.

[0044] Please refer to Figure 2 , Figure 3 and Fig.10 A temperature measuring mechanism 11 is provided between the coarse grinding roller 401 and the fine grinding roller 402 and on the side close to the fine grinding roller 402. The temperature measuring mechanism 11 includes a mounting frame 1101. A plurality of infrared temperature sensors 1102 are installed on one side of the mounting frame 1101. The model of the infrared temperature sensor 1102 is FST600-400. The mounting frame 1101 is fixedly connected to the bed 1 by bolts. A speed regulator 406 is fixedly installed on the top of the servo motor 405. A control box 7 is fixedly installed on the front side of the bed 1. The model of the control box 7 is BXK-T. The speed regulator 406 and the infrared temperature sensor 1102 are both electrically connected to the control box 7.

[0045] Specifically, the threshold of the temperature parameter is set by the control box 7, and the temperature of the bottom surface of the wooden structure is scanned by the infrared temperature sensor 1102 and fed back to the control box 7. When the scanned temperature is higher than the threshold, the control box 7 cooperates with the speed regulator 406 to reduce the rotation speed of the servo motor 405 to avoid excessive temperature of the bottom surface of the wooden structure during the grinding process due to excessively high rotation speed of the servo motor 405, thereby causing deformation and cracking of the bottom surface of the wooden structure.

[0046] Please refer to Figure 1 and Fig.11 The filter mechanism 10 includes a filter frame 1001, and a filter screen 1002 is fixedly connected to one side of the filter frame 1001. The filter frame 1001 is snap-fitted to the bed 1, and the filter mechanism 10 is located between the negative pressure fan 9 and the anti-blocking mechanism 3. A side of the filter screen 1002 close to the anti-blocking mechanism 3 is located in the same vertical plane as an inner wall of one side of the collection box 501.

[0047] Specifically, the filter 1002 is provided to filter smaller wood chips and dust particles, thereby preventing the wood chips and dust from following the flow of air and entering the surrounding environment. When the filter frame 1001 is pulled out, the wood chips and dust attached to one side of the filter 1002 are scraped off through the inner wall of the bed 1, so that the wood chips and dust fall into the collection box 501, thereby facilitating the cleaning and collection of the wood chips and dust.

[0048] How it works First, the threshold of the temperature parameter is set through the control box 7, the wooden structure to be polished is placed on the top of the bed 1, the pressure mechanism 8 is adjusted to press the wooden structure, and then the hand wheel 602 is turned to drive the slide bar 601 to rotate, and then the threaded groove 609 is cooperated to drive the adapter sleeve 603 to move, thereby cooperating with the connecting rod 606 to drive the base 607 to rise, so that two of the cleaning brushes 608 are attached to the bottom of the polishing mechanism 4, and the other cleaning brush 608 is attached to the bottom surface of the wooden structure, and the negative pressure fan 9 and the servo motor 405 are started at the same time. After the servo motor 405 is started, the sprocket is driven 403 and the coarse grinding roller 401 rotate, and then cooperate with the chain 404 and another sprocket 403 to drive the fine grinding roller 402 to rotate, and the wooden structure is polished by the rotating coarse grinding roller 401 and the fine grinding roller 402, so that the coarse grinding and fine grinding processes are completed successively, and the grinding efficiency is improved. After the negative pressure fan 9 is started, a negative pressure is formed inside the bed 1, and the wood chips and dust formed during the grinding of the wooden structure are sucked into the inside of the bed 1. When the airflow flows through the mesh cylinder 302, the wood chips and dust with larger particles are intercepted by the mesh cylinder 302, so as to avoid clogging the filter mechanism 10 The mesh cylinder 302 is blocked, and when the wooden structure moves, due to the friction between the wooden structure and the mesh cylinder 302, the mesh cylinder 302 rolls. During the rolling process, the scraper 303 scrapes off the wood chips and dust attached to the surface of the mesh cylinder 302 to avoid blockage caused by excessive wood chips and dust, so as to facilitate the recycling of the mesh cylinder 302. During the grinding process, the cleaning brush 608 is used to sweep away the wood chips attached to the surface of the grinding mechanism 4 and the bottom of the wooden structure. The wood chips formed during the grinding process and the cleaned wood chips fall into the middle collection box 501 to be collected, so as to avoid wood chips. The wood chips are scattered everywhere, making it difficult to clean. The temperature of the bottom surface of the wooden structure is scanned by the infrared temperature sensor 1102 and fed back to the control box 7. When the scanned temperature is higher than the threshold, the control box 7 cooperates with the speed regulator 406 to reduce the speed of the servo motor 405 to avoid excessive temperature of the bottom surface of the wooden structure during the grinding process due to excessive speed of the servo motor 405, thereby causing deformation and cracking of the bottom surface of the wooden structure. At the same time, the cleaning brush 608 is used to clean the bottom surface of the wooden structure after rough grinding to prevent the residual wood chips from affecting the temperature measurement of the infrared temperature sensor 1102.
