Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] refer to Figure 1-Figure 7 , a grinding tool for making wood chip handicrafts, comprising: Polish the box 100; The grinding part 101 disposed in the grinding box 100 is used for rotating and grinding the wood chip crafts; A frame 102 is disposed on the polishing box 100, a dust extraction chamber 103 is formed in the frame 102, and a plurality of exhaust fans 104 are disposed in the dust extraction chamber 103; A connection port 501105 is provided at the bottom of the dust extraction chamber 103, and a filter bag 106 is provided in the connection port 501105; A connecting rod 107 is disposed in the dust extraction chamber 103, and a connecting frame 108 connected to the filter bag 106 is disposed on the connecting rod 107. A baffle 109 is disposed on the connecting rod 107, and the baffle 109 has a diameter larger than that of the connecting frame 108 and is located at the bottom of the filter bag 106; A plurality of atomizing nozzles 110 provided at the bottom of the baffle 109 are used for spraying water to reduce dust; Two sleeves 111 are provided at the bottom of the frame 102, and the two sleeves 111 can form a tube surrounding the filter bag 106 when combined; The dust reduction component provided between the frame 102 and the polishing box 100 is used to move the position of the connecting frame 108 so that the filter bag 106 is turned over in the dust extraction chamber 103 and the liquid in the polishing box 100 is transported to the atomizing nozzle 110; Wherein, the dust suppression 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 suppression component can move the position of the sleeve 111 to be close to each other and surround the filter bag 106 when the connecting frame 108 is reset downward. When the two sleeves 111 move to a preset position close to the filter bag 106, the baffle 109 can rotate; By setting the polishing part 101, the polishing part 101 can be started when applied to generate rotation to polish and shape the wood chip crafts. At this time, the operator can turn on the exhaust fan 104 and use the dust reduction component to move the position of the connecting frame 108 upward. When the connecting frame 108 moves upward, it can drive one end of the filter bag 106 to move. When the connecting frame 108 moves upward to the preset position, the filter bag 106 can be turned over by using the softness of the filter bag 106. When the exhaust fan is working, the gas in the frame 102 can be attracted to pass through the filter bag 106, and the dust is collected in the filter bag 106, and the dust brought by the polishing and shaping work in the frame 102 is extracted to achieve the purpose of dust reduction, and effective filtering is performed, so that the extracted debris will not be directly discharged to the external environment, avoiding secondary pollution. When the polishing work is suspended or terminated, the operator stops the exhaust fan 104. The position of the mobile connecting frame 108 is reset downward by the dust reduction component. In this process, the dust accumulated on the surface of the filter bag 106 can be shaken off onto the baffle 109 by gravity by the flip design of the filter bag 106. The baffle 109 temporarily receives the dust, and the liquid in the polishing box 100 can be transported to the atomizing nozzle 110, which sprays the atomized dust reduction liquid. When the two sleeves 111 move to the preset position close to the filter bag 106, the outer wall and the bottom of the filter bag 106 can be surrounded, and the baffle 109 starts to rotate. When the baffle 109 rotates, the centrifugal force can be used to release the debris temporarily stored on the baffle 109 into the sleeve 111, and the filtered dust can be collected. In addition, when the baffle 109 rotates, the atomizing nozzle 110 can also rotate, so that the sprayed atomized liquid can diffuse the sleeve 111 as much as possible, and dust the debris falling from the baffle 109 and the filter bag 106, so as to prevent the residual debris from being raised when the filter bag 106 is turned over again, affecting the dust reduction effect of the space in the frame 102. In this application, the exhaust fan 104, the filter bag 106, the baffle 109, the atomizing nozzle 110 and the dust reduction components work together to solve the problem that the debris and dust generated during the polishing and shaping of wood chip crafts affect the polishing work. The operation of the exhaust fan 104 can quickly suck the dust generated during the grinding process into the frame 102, and efficiently filter it through the filter bag 106 to prevent debris from being directly discharged into the external environment and causing pollution; the design of the dust reduction component can realize the automatic flipping of the filter bag 106, and shake the accumulated dust onto the baffle 109, so as to avoid the clogging of the filter bag 106 and affect the filtering effect; when the baffle 109 rotates, the centrifugal force is used to release the temporarily stored dust into the sleeve 111 for centralized collection, so as to ensure the continuity and thoroughness of the dust treatment; the atomizing nozzle 110 evenly covers the filter bag 106, the baffle 109 and the surrounding area by rotating and spraying atomized liquid, so as to reduce the residual dust and prevent secondary pollution of dust, so as to further optimize the grinding environment and improve the overall grinding efficiency and product processing quality.

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

[0020] As a further solution of the present invention, the dust suppression 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 is threadedly connected to the lead screw a205, and a chain transmission mechanism 206 is provided between the lead screw a205 and the worm 204; By setting up the chain transmission 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, during this process, the chain transmission mechanism 206 can be used to rotate the screw a205 to use the force of the thread to move the position of the sleeve 111, so that the sleeve 111 leaves the filter bag 106, forming conditions for the passage of gas.

[0021] As a further solution of the present invention, the dust reduction component also includes a connecting shaft 300 rotatably connected to the bottom of the connecting rod 107, the baffle 109 and the atomizing nozzle 110 are connected to the connecting shaft 300, a transmission shaft 301 is rotatably connected in the connecting rod 107, the bottom of the transmission shaft 301 extends to the bottom of the connecting shaft 300 and is connected to a boss 302, a synchronous wheel 303 is provided on the connecting rod 107 and one of the rotating shafts 201, a synchronous belt 304 is provided between the two synchronous wheels 303, a limiting frame 305 is provided in the synchronous wheel 303 on the connecting rod 107, the top of the transmission shaft 301 is slidably connected in the limiting frame 305, a limiting disk 306 is connected to the transmission shaft 301, a plurality of elastic rods 307 are connected in the connecting rod 107, and a spring b308 is provided between the limiting disk 306 and the connecting rod 107; By setting the spring b308, the spring b308 can limit the position of the transmission rod, so that in the initial state, the limit plate 306 on it is not sleeved with the elastic rod 307. When the worm 204 rotates through the worm wheel 203 to rotate the rotating shaft 201, so that it rotates 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 synchronous belt 304, the synchronous wheel 303, and the limit frame 305 can allow the transmission shaft 301 to rotate. Since the limit plate 306 is not sleeved with the elastic rod 307 at this time, the transmission shaft 301 is currently located in the connecting shaft 300 and is in an idling state. During the continuous downward movement and connection, the two sleeves 111 gradually approach the filter bag 106. 6 until the two sleeves 111 contact each other. At this time, the sleeve 111 can be used to squeeze the position of the boss 302, so that the boss 302 moves upward, and the limit plate 306 moves upward close to the elastic rod 307. As the transmission shaft 301 continues to rotate, the limit plate 306 and the elastic rod 307 can be set. When the transmission shaft 301 rotates, the limit plate 306 and the elastic rod 307 can be used to rotate the connecting shaft 300, so that the rotation of the connecting shaft 300 can be realized, and the baffle 109 and the atomizing nozzle 110 thereon can be driven to rotate. The purpose of this setting is to allow the sleeve 111 to merge and close the space on the outer wall of the filter bag 106, and then allow the baffle 109 to rotate, and use centrifugal force to release the dust and debris temporarily received on the baffle 109, so as to prevent the dust and debris from leaking out before the sleeve 111 merges and causes environmental pollution.

[0022] As a further solution of the present invention, a reel 309 is connected to the rotating shaft 201, the traction rope 202 is connected to the reel 309, and a ratchet mechanism a310 is provided between the reel 309 and the rotating shaft 201; As a further solution 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 member 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 groove 313 is connected to the worm 204, one end of the top rod 314 is semi-spherical, the top groove 313 is a semi-spherical groove, and a spring c315 is connected between the top rod 314 and the worm 204; By setting the ratchet mechanism a310, when the dust reduction work starts, the forward rotation of the worm 204 can rotate the reel 309 through the worm wheel 203, the rotating shaft 201, and the ratchet mechanism a310, and the reeling traction rope 202 lifts the position of the connecting frame 108 upward. When the subsequent grinding work is suspended or terminated, the worm 204 can be rotated in the opposite direction, and the worm 204 can make the rotating shaft 201 rotate in the opposite direction through the worm wheel 203. The connecting frame 108 is reset downward by the force of the spring a200, and the reel 309 can be pulled by the traction rope 202 to rotate, that is, when the worm 204 rotates in the opposite direction and the connecting frame 108 has not yet reset to the origin, the rotating shaft 201 and the reel 309 rotate synchronously, which will not affect the normal reset process. However, after the connecting frame 108 is reset to the origin, the rotating shaft 201 still needs to continue to rotate to rotate the transmission shaft 301 through the synchronous belt 304 and the synchronous wheel 303. For this purpose, a ratchet mechanism is provided. After the connecting frame 108 is reset to the origin, the rotating shaft 201 can continue to rotate to drive the transmission shaft 301 to rotate, so that the baffle 109 can be rotated to release the dust on the baffle 109 by centrifugal force. In the process of releasing the dust, the position of the connecting frame 108 will not be interfered, and the stability of the release process is guaranteed. In addition, by providing a spring c315, the spring c315 can be used to make the top rod 314 touch the top groove 313, and the two can form a certain friction force, so that when the worm 204 rotates, the sprocket 311 can be rotated by the friction force, so that the transmission screw rotates. When the screw rotates to move the sleeve 111 to the extreme position, when the worm 204 continues to rotate, the rotation of the worm 204 can overcome the force of the spring c315, so that the top groove 313 and the top rod 314 are separated, so that the worm 204 can be idle on the sprocket 311, avoiding the problem of motion conflict.

[0023] As a further solution 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, 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 is in contact with one of the annular grooves 402; By setting the vibration rod 400, under the action of the spring d401, the vibration rod 400 can contact one of the annular grooves 402. The purpose of this setting is that when the connecting frame 108 moves up and down along the connecting rod 107, the vibration rod 400 can continuously contact one of the annular grooves 402 as the connecting frame 108 moves, and a certain vibration force will be generated during the continuous separation and sleeve process. This part of the vibration force is transmitted to the connecting frame 108 and also gives the filter bag 106 a vibration force. When the connecting frame 108 moves downward to reset, it can promote the shaking off of dust in the filter bag 106 to a certain extent.

The outer wall of the manifold 502 is connected with multiple atomizing nozzles 110, ensuring that the liquid can be evenly sprayed through the atomizing nozzles 110 to achieve a comprehensive dust reduction effect.

[0025] As a further solution of the present invention, the bottom of the rotating shaft 201 is connected with a screw b503, and the screw b503 is a reciprocating screw.
