[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] refer to Figures 1-7 A grinding tool for making wood chip crafts, comprising: Grind the housing to 100mm. The sanding section 101, located inside the sanding box 100, is used for rotating and sanding wood chip handicrafts. A frame 102 is provided on the grinding box 100, and a dust extraction chamber 103 is formed inside the frame 102. A plurality of exhaust fans 104 are provided inside the dust extraction chamber 103. A second connection port 501 is provided at the bottom of the dust extraction chamber 103, and a filter bag 106 is provided inside the second connection port 501. A connecting rod 107 is provided in the dust extraction chamber 103. A connecting frame 108 is provided on the connecting rod 107 to connect with the filter bag 106. A baffle 109 is provided on the connecting rod 107. The diameter of the baffle 109 is larger than that of the connecting frame 108 and it is located at the bottom of the filter bag 106. Multiple atomizing nozzles 110 located at the bottom of the baffle 109 are used for spraying water to suppress dust. Two sleeves 111 are provided at the bottom of the frame 102. The two sleeves 111 can be combined to form a tube that surrounds the filter bag 106. A dust-reducing component located between the frame 102 and the grinding chamber 100 is used to move the position of the connecting frame 108 so that the filter bag 106 flips over into the dust extraction chamber 103 and delivers the liquid in the grinding chamber 100 to the atomizing nozzle 110. The dust-reducing component can move the position of the sleeve 111 away from each other and away from the filter bag 106 when the connecting frame 108 moves upward; The dust-reducing component can move the position of the sleeve 111 so that they move closer to each other and surround the filter bag 106 when the connecting frame 108 moves downward to reset. When the two sleeves 111 move to a preset position near the filter bag 106, the baffle 109 can rotate; By setting up the sanding section 101, it can be activated during application to generate rotation for sanding and shaping of wood chip crafts. At this time, the operator can turn on the exhaust fan 104 and use the dust-suppressing components to move the connecting frame 108 upwards. As the connecting frame 108 moves upwards, it can move one end of the filter bag 106. When the connecting frame 108 moves to the preset position, the filter bag 106 can be flipped over due to its flexibility. When the exhaust fan is working, the gas in the frame 102 is drawn through the filter bag 106, collecting dust inside. This removes dust from the frame 102 caused by the sanding and shaping work, achieving dust suppression and effective filtration, preventing the extracted debris from being directly discharged into the external environment and avoiding secondary pollution. When the sanding work is stopped or terminated, the operator stops the operation of the exhaust fan 104. The dust-suppressing component lowers and resets the position of the moving connecting frame 108. During this process, the flipping design of the filter bag 106 allows gravity to shake off the accumulated dust on the surface of the filter bag 106 onto the baffle 109, where the baffle 109 temporarily receives the dust. Meanwhile, the liquid in the polishing chamber 100 is conveyed to the atomizing nozzle 110, which sprays atomized dust-suppressing liquid. When the two sleeves 111 move close to the filter bag 106 to a preset position, they surround the outer wall and bottom of the filter bag 106, and the baffle 109 begins to rotate. As the baffle 109 rotates, centrifugal force releases the temporarily stored debris onto the sleeves 111, collecting the filtered dust. Furthermore, when the baffle 109 rotates, the atomizing nozzle 110 also rotates, allowing the sprayed atomized liquid to spread as much as possible across the sleeve 111, suppressing dust from the debris falling from the baffle 109 and filter bag 106. This prevents residual debris from being stirred up when the filter bag 106 is flipped again, thus affecting the dust suppression effect within the frame 102. In this application, the coordinated operation of the exhaust fan 104, filter bag 106, baffle 109, atomizing nozzle 110, and dust suppression components solves the problem of dust and debris affecting the sanding process during the sanding and shaping of wood chip crafts. The operation of the exhaust fan 104 can quickly draw the dust generated during the grinding process into the frame 102, where it is efficiently filtered through the filter bag 106, preventing debris from being directly discharged into the external environment and causing pollution. The dust suppression component is designed to automatically flip the filter bag 106, shaking the accumulated dust onto the baffle 109, avoiding filtration effects caused by clogging of the filter bag 106. When the baffle 109 rotates, it uses centrifugal force to release the temporarily stored dust into the sleeve 111 for centralized collection, ensuring the continuity and thoroughness of dust treatment. The atomizing nozzle 110 sprays atomized liquid through rotation, evenly covering the filter bag 106, baffle 109 and the surrounding area, to suppress residual dust, prevent secondary dust pollution, further optimize the grinding environment, and improve the overall grinding efficiency and product processing quality.

[0019] As a further embodiment of the present invention, the dust suppression component includes a spring a200 connected between the connecting frame 108 and the dust extraction chamber 103, a rotating shaft 201 rotatably connected inside the dust extraction chamber 103, a traction rope 202 connected to the rotating shaft 201, one end of the traction rope 202 being connected to the connecting frame 108, a worm gear 203 being provided on the rotating shaft 201, and a worm 204 rotatably connected inside the dust extraction chamber 103 and meshing with the worm gear 203; By setting spring a200, spring a200 can use its own potential energy to limit the position of connecting frame 108. When dust suppression is carried out in frame 102, the rotation of worm 204 can be used to rotate shaft 201 through worm wheel 203 to wind up traction rope 202, forcing connecting frame 108 to move upward, thereby achieving the purpose of turning filter bag 106 over.

[0020] As a further embodiment of the present invention, the dust-reducing component further includes a lead screw a205 rotatably connected to the bottom of the frame 102, the sleeve 111 is slidably connected to the bottom of the frame 102 and threadedly connected to the lead screw a205, and a chain transmission mechanism 206 is provided between the lead screw a205 and the worm gear 204. By setting up a chain drive mechanism 206, when the worm 204 rotates to move the connecting frame 108 upward through the worm wheel 203, the rotating shaft 201, and the traction rope 202, the chain drive mechanism 206 can be used to rotate the lead screw a205, thereby using the force of the thread to move the position of the sleeve 111, so that the sleeve 111 leaves the filter bag 106, thus creating conditions for gas passage.

[0021] As a further embodiment of the present invention, the dust suppression component further includes a connecting shaft 300 rotatably connected to the bottom of the connecting rod 107, the baffle 109 and the atomizing nozzle 110 being connected to the connecting shaft 300, a drive shaft 301 rotatably connected inside the connecting rod 107, the bottom of the drive shaft 301 extending to the bottom of the connecting shaft 300 and connected to a boss 302, a synchronous pulley 303 being provided on the connecting rod 107 and one of the rotating shafts 201, a synchronous belt 304 being provided between the two synchronous pulleys 303, a limiting frame 305 being provided inside the synchronous pulley 303 on the connecting rod 107, the top of the drive shaft 301 being slidably connected to the limiting frame 305, a limiting disc 306 being connected to the drive shaft 301, a plurality of elastic rods 307 being connected inside the connecting rod 107, and a spring b308 being provided between the limiting disc 306 and the connecting rod 107; By setting spring b308, the position of the transmission rod can be limited, so that in the initial state, the limiting plate 306 on it is not engaged with the elastic rod 307. When the worm gear 204 rotates, it causes the rotating shaft 201 to rotate through the worm wheel 203, causing it to rotate in the opposite direction to release the traction rope 202. The connecting frame 108 gradually moves downward to flip the filter bag 106. During this process, the timing belt 304, timing wheel 303, and limiting frame 305 allow the transmission shaft 301 to rotate. Since the limiting plate 306 is not engaged with the elastic rod 307 at this time, the transmission shaft 301 is currently in an idle state within the connecting shaft 300. During the continuous downward movement of the connection, the two sleeves 111 gradually approach the filter bag 106. 6. Move the sleeves 111 until they contact each other. At this point, the sleeves 111 can be used to press the boss 302, causing the boss 302 to move upward and the limiting plate 306 to move upward and closer to the elastic rod 307. As the drive shaft 301 continues to rotate, the limiting plate 306 and the elastic rod 307 can be fitted together. When the drive shaft 301 rotates, the connecting shaft 300 can be rotated through the limiting plate 306 and the elastic rod 307, thus achieving the rotation of the connecting shaft 300 and driving the baffle 109 and the atomizing nozzle 110 on it to rotate. The purpose of this setting is to allow the sleeves 111 to close and seal the space on the outer wall of the filter bag 106 before allowing the baffle 109 to rotate, using centrifugal force to release the dust and debris temporarily held on the baffle 109, preventing dust and debris from leaking out and causing environmental pollution before the sleeves 111 close.

[0022] As a further embodiment of the present invention, a winding shaft 309 is connected to the rotating shaft 201, the traction rope 202 is connected to the winding shaft 309, and a ratchet mechanism a310 is provided between the winding shaft 309 and the rotating shaft 201. As a further embodiment of the present invention, the chain transmission mechanism 206 includes a sprocket 311 connected to the worm 204 and the lead screw a205, a chain transmission component 312 is provided between the two sprockets 311, a plurality of top grooves 313 are provided on the inner wall of the sprocket 311 on the worm 204, a top rod 314 adapted to the top grooves 313 is connected to the worm 204, one end of the top rod 314 is hemispherical, the top groove 313 is a hemispherical groove, and a spring c315 is connected between the top rod 314 and the worm 204; By setting a ratchet mechanism a310, at the start of dust suppression, the forward rotation of the worm 204 causes the take-up shaft 309 to rotate via the worm wheel 203, rotating shaft 201, and ratchet mechanism a310, lifting the connecting frame 108 upwards via the take-up traction rope 202. When subsequent grinding work is stopped or terminated, the worm 204 can be rotated in the reverse direction. The worm 204, via the worm wheel 203, causes the rotating shaft 201 to rotate in the reverse direction. The connecting frame 108 moves downwards under the force of the spring a200, and the take-up shaft 309 can be rotated via the traction rope 202. That is, when the worm 204 rotates in the reverse direction and the connecting frame 108 has not yet returned to its original position, the rotating shaft 201 and the take-up shaft 309 rotate synchronously, without affecting the normal reset process. However, after the connecting frame 108 returns to its original position, the rotating shaft 201 still needs to continue rotating to rotate the drive shaft 301 via the synchronous belt 304 and synchronous pulley 303. To address this, a ratchet mechanism is provided. After the connecting frame 108 returns to its original position, the rotating shaft 201 continues to rotate, driving the transmission shaft 301 to rotate. This allows the baffle 109 to rotate, using centrifugal force to release dust from the baffle 109. During dust release, the position of the connecting frame 108 is not interfered with, ensuring stability during the release process. Furthermore, by providing a spring c315, the push rod 314 can contact the top groove 313, creating friction. This friction causes the sprocket 311 to rotate when the worm 204 rotates, thus driving the lead screw to rotate. When the lead screw rotates and moves the sleeve 111 to its limit position, the rotation of the worm 204 overcomes the force of the spring c315, causing the top groove 313 to disengage from the push rod 314. This allows the worm 204 to idle on the sprocket 311, avoiding motion interference.

[0023] As a further embodiment of the present invention, a vibration rod 400 is connected to the connecting frame 108, a spring d401 is provided between the vibration rod 400 and the connecting frame 108, and a plurality of annular grooves 402 are provided on the outer wall of the connecting rod 107, and one end of the vibration rod 400 contacts one of the annular grooves 402. By setting up a vibrating rod 400, under the action of spring d401, the vibrating rod 400 can contact one of the annular grooves 402. The purpose of this setting is that, as the connecting frame 108 moves up and down along the connecting rod 107, the vibrating rod 400 continuously contacts one of the annular grooves 402 as the connecting frame 108 moves. During the continuous disengagement and engagement process, a certain amount of vibration force is generated. This vibration force is transmitted to the connecting frame 108 and also provides a vibration force to the filter bag 106. When the connecting frame 108 moves downward to reset, it can promote the shaking off of dust from the filter bag 106 to a certain extent.

[0024] As a further embodiment of the present invention, the dust suppression component further includes a conveying pipe 500 connected to the frame 102, one end of the conveying pipe 500 being connected to the connecting rod 107, the outer wall of the connecting shaft 300 having a plurality of connection ports 105, the outer wall of the connecting shaft 300 being fitted with a collecting pipe 502, the atomizing nozzle 110 being connected to the collecting pipe 502, and the baffle 109 being connected to the collecting pipe 502; By designing the delivery pipe 500 to connect with the connecting rod 107, liquid in the grinding chamber 100 is introduced into the connecting rod 107 through the delivery pipe 500. The liquid then flows into the manifold 502 through multiple connection ports 105 on the connecting shaft 300, forming an efficient liquid delivery path. Multiple atomizing nozzles 110 are connected to the outer wall of the manifold 502 to ensure that the liquid is evenly sprayed through the atomizing nozzles 110, achieving a comprehensive dust suppression effect.

[0025] As a further embodiment of the present invention, a lead screw b503 is connected to the bottom of the rotating shaft 201. The lead screw b503 is a reciprocating lead screw. A push plate 504 is slidably connected inside the grinding box 100. A threaded pipe 505 that is threadedly connected to the lead screw b503 is connected to the top of the push plate 504. A one-way valve 506 is provided on the push plate 504. By setting a lead screw b503, the lead screw b503 can drive the push plate 504 to reciprocate up and down along the box body when it rotates. The push plate 504 is equipped with a one-way valve 506, which can control the unidirectional flow of gas during the movement. When the connecting plate moves up and down, the push plate 504 pressurizes the grinding box 100, and the pressure can be used to force liquid into the atomizing nozzle 110 for spraying and dust suppression.

[0026] A method for making wood chip handicrafts includes: Step 1: Use sawdust as the main raw material, and screen the sawdust with a suitable particle size to ensure the uniformity of the raw material. Depending on the requirements, appropriate amounts of adhesive, pigment, or other additives can be added. Mix the sawdust and adhesive in a specific ratio until a uniform mixture is formed. Step Two: Load the prepared mixture into a pre-designed mold, and shape the mixture within the mold using pressing or injection. Depending on product requirements, cold pressing or hot pressing can be selected. After molding, allow it to stand for a period of time to allow the initial shape to set. Step 3: Curing the pre-formed wood chip craft blank. Depending on the process requirements, natural drying or oven drying can be used to fully cure the adhesive, thereby enhancing the strength and durability of the craft. Step 4: Use an abrasive to finely polish the surface of the craft item, removing rough areas and making it smoother and more aesthetically pleasing. A dust collection device can be used during the polishing process to reduce environmental pollution. Step 5: According to the design requirements, perform surface treatment on the polished crafts, such as painting, waxing, or spraying a transparent protective film, to enhance the surface gloss and durability.
