[0021] The method of using the wood grinding device is as follows:

[0022] S1: The user places the wood to be polished on the processing table, and then starts the servo motor. The output shaft of the servo motor will drive the driving gear ring to rotate through the transmission cylinder, and the driving gear ring will drive the transmission gear and the connecting shaft to rotate, and the transmission gear will drive the inner gear ring to rotate synchronously. The pressure bump on the inner gear ring will apply pressure to the inclined groove on the polishing ring. At this time, the two polishing rings will start to rotate, and the loading frame will be driven to move toward the wood through the hydraulic rod on the processing table, so that the rotating polishing ring can start to roughly polish the surface of the wood;

[0023] S2: When fine grinding is required on the wood surface, the user controls the servo motor to rotate in the reverse direction through the device system. As can be seen from the above steps, the grinding ring will rotate in the reverse direction at this time. Since the one-way groove on the grinding ring is fitted with one-way teeth, the one-way teeth will limit the reverse rotation of the grinding ring at this time, and the pressure protrusion on the inner gear ring will continue to apply reverse pressure to the inclined groove on the grinding ring. At this time, the pressure protrusion can push the grinding ring to move axially, so that the two grinding rings move away from each other, thereby exposing the grinding belt between the support plates;

[0024] S3: Then the device system controls the vertical electric cylinder to start, and the vertical electric cylinder drives the extrusion frame to move downward synchronously through the guide plate. During this process, the extrusion frame will drive the sanding belt to move synchronously, so that the sanding belt wrapped on the corresponding winding wheel is pulled out. When the extrusion frame and the guide wheel drive the sanding belt to fit the wood, the transverse electric cylinder is started, and the transverse electric cylinder will push the transmission cylinder to move through the moving frame, so that the transmission cylinder drives the driving gear ring and the docking sleeve to move synchronously, the driving gear ring is separated from the transmission gear, and the force block will enter the docking groove on the docking sleeve, and the pressure spring is used to provide auxiliary pressure;

[0025] S4: When the output shaft of the servo motor drives the transmission cylinder to rotate, the transmission cylinder will drive the force block to rotate synchronously through the limit block and the docking sleeve, and the force block will drive the transmission rod connected to the bottom to rotate, and the transmission rod will drive the cam to rotate. The cam is used to drive the moving frame to move back and forth along the guide frame. At this time, the one-way toothed plates on both sides of the moving frame alternately drive the corresponding ratchet wheels to rotate, so that the ratchet wheels drive the corresponding winding wheels to rotate through the control rod, so that the two winding wheels can alternately pull the sanding belts. At this time, the moving sanding belts can fine-grind the wood surface. In addition, the user can also manually adjust through the grip of the control rod.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the wood grinding device for processing balcony sunscreen cabinets and the use method thereof have two grinding modes, namely, rough grinding and fine grinding. The grinding ring for rough grinding of the device adopts a detachable split structure, and the fine grinding structure composed of the grinding belt can quickly fine grind the wood surface by reciprocating pulling. The specific contents are as follows:

[0027] 1. A vertical one-way tooth is arranged on the top side of the inner gear ring. The top of the one-way tooth is fitted in the inclined surface of the one-way groove to form a one-way limiting structure. The lower part of the one-way tooth is slidably inserted on the loading frame. The bottom surface of the one-way tooth is elastically connected to the inner wall of the loading frame through a spring. An inclined groove is opened on the inner wall of the middle part of the grinding ring. A pressure protrusion is slidably fitted inside the higher end of the inclined groove. The end of the pressure protrusion is fixedly connected to the outer wall of the inner gear ring. When the inner gear ring rotates in the opposite direction, the one-way tooth forms a one-way limiting structure of the grinding ring. At this time, the pressure protrusion on the inner gear ring can push the grinding ring to move through the inclined groove, so that the two grinding rings are separated from each other.

[0028] 2. One end of the transmission rod away from the transmission cylinder is fixedly installed on the cam, and the cam is fitted on the side wall of the supporting plate, and the upper and lower ends of the cam are fitted on the inner wall of the moving frame. Two groups of one-way toothed plates and ratchet wheels with symmetrical distribution of the center are arranged on both sides of the moving frame. The one-way toothed plate is slidably embedded in the mounting groove of the moving frame, and a reset spring with equal spacing is fixedly connected between one side of the one-way toothed plate and the inner wall of the moving frame. A corresponding ratchet wheel is arranged at the teeth on the other side of the one-way toothed plate to form a one-way transmission structure. The side of the ratchet wheel away from the positioning sleeve is fixedly connected to the foot plate at the end of the control rod by bolts. When the transmission rod drives the cam to rotate, the cam will drive the moving frame to move synchronously, so that the one-way toothed plate on the moving frame can drive the corresponding ratchet wheel to rotate, and the two ratchets will rotate alternately, and the ratchet wheel drives the winding wheel to rotate synchronously through the control rod, so that the winding wheel can drive the grinding belt to move.

[0049] The method of using the wood grinding device is as follows:

[0050] S1: The user places the wood to be polished on the processing table 1, and then starts the servo motor 16. The output shaft of the servo motor 16 will drive the driving gear ring 1302 to rotate through the transmission cylinder 1301, and the driving gear ring 1302 will drive the transmission gear 11 and the connecting shaft 12 to rotate, and the transmission gear 11 will drive the inner gear ring 5 to rotate synchronously, and the pressure protrusion 8 on the inner gear ring 5 will apply pressure to the inclined groove 7 on the polishing ring 6. At this time, the two polishing rings 6 will start to rotate, and the loading frame 2 will be driven to move toward the wood through the hydraulic rod on the processing table 1, so that the rotating polishing ring 6 can start to roughly polish the surface of the wood;

[0051] S2: When fine grinding is required on the wood surface, the user controls the servo motor 16 to rotate in the reverse direction through the device system. As can be seen from the above steps, the grinding ring 6 will rotate in the reverse direction at this time. Since the one-way groove 9 on the grinding ring 6 is fitted with the one-way teeth 10, the one-way teeth 10 will limit the reverse rotation of the grinding ring 6, and the pressure protrusion 8 on the inner gear ring 5 will continue to apply reverse pressure to the inclined groove 7 on the grinding ring 6. At this time, the pressure protrusion 8 can push the grinding ring 6 to move axially, so that the two grinding rings 6 move away from each other, thereby exposing the grinding belt 27 between the support plates 3;

[0052] S3: Then the device system controls the vertical electric cylinder 31 to start, and the vertical electric cylinder 31 drives the extrusion frame 29 to move downward synchronously through the guide plate 30. During this process, the extrusion frame 29 will drive the sanding belt 27 to move synchronously, so that the sanding belt 27 wound on the corresponding winding wheel 26 is pulled out. When the extrusion frame 29 and the guide wheel 28 drive the sanding belt 27 to fit the wood, the transverse electric cylinder 15 is started, and the transverse electric cylinder 15 will push the transmission cylinder 1301 to move through the moving frame 14, so that the transmission cylinder 1301 drives the driving gear ring 1302 and the docking sleeve 1303 to move synchronously, and the driving gear ring 1302 is separated from the transmission gear 11, and the force block 18 will enter the docking groove 1306 on the docking sleeve 1303, and the pressure spring 1305 is used to provide auxiliary pressure;

[0053] S4: When the output shaft of the servo motor 16 drives the transmission cylinder 1301 to rotate, the transmission cylinder 1301 will drive the force block 18 to rotate synchronously through the limit block 1304 and the docking sleeve 1303, and the force block 18 will drive the transmission rod 17 connected to the bottom to rotate, and the transmission rod 17 will drive the cam 19 to rotate. The cam 19 is used to drive the moving frame 20 to move back and forth along the guide frame 32. At this time, the one-way tooth plates 21 on both sides of the moving frame 20 alternately drive the corresponding ratchet wheels 23 to rotate, so that the ratchet wheels 23 drive the corresponding winding wheels 26 to rotate through the control rod 25, so that the two winding wheels 26 can alternately pull the sanding belts 27. At this time, the moving sanding belts 27 can finely grind the wood surface. In addition, the user can also manually debug through the grip of the control rod 25.

The method for using the wood grinding device for processing balcony sun protection cabinets according to claim 1, characterized in that: The method of using the wood grinding device is as follows: S1: The user places the wood to be polished on the processing table (1), and then starts the servo motor (16). The output shaft of the servo motor (16) drives the driving gear ring (1302) to rotate through the transmission cylinder (1301), and the driving gear ring (1302) drives the transmission gear (11) and the connecting shaft (12) to rotate, and the transmission gear (11) drives the inner gear ring (5) to rotate synchronously. The pressure protrusion (8) on the inner gear ring (5) applies pressure to the inclined groove (7) on the polishing ring (6). At this time, the two polishing rings (6) start to rotate, and the loading frame (2) is driven to move toward the wood through the hydraulic rod on the processing table (1), so that the rotating polishing ring (6) can start to roughly polish the surface of the wood; S2: When fine grinding of the wood surface is required, the user controls the servo motor (16) to rotate in the reverse direction through the device system. As can be seen from the above steps, the grinding ring (6) will rotate in the reverse direction at this time. Since the one-way groove (9) on the grinding ring (6) is fitted with a one-way tooth (10), the one-way tooth (10) will limit the reverse rotation of the grinding ring (6), and the pressure protrusion (8) on the inner gear ring (5) will continue to apply reverse pressure to the inclined groove (7) on the grinding ring (6). At this time, the pressure protrusion (8) can push the grinding ring (6) to move axially, so that the two grinding rings (6) move away from each other, thereby exposing the grinding belt (27) between the support plates (3); S3: Then the device system controls the vertical electric cylinder (31) to start, and the vertical electric cylinder (31) drives the extrusion frame (29) to move downward synchronously through the guide plate (30). During this process, the extrusion frame (29) drives the sanding belt (27) to move synchronously, so that the sanding belt (27) wound on the corresponding winding wheel (26) is pulled out. When the extrusion frame (29) and the guide wheel (28) drive the sanding belt (27) to fit on the wood, the horizontal electric cylinder (1 5) Start, the transverse electric cylinder (15) will push the transmission cylinder (1301) to move through the moving frame (14), so that the transmission cylinder (1301) drives the driving gear ring (1302) and the docking sleeve (1303) to move synchronously, the driving gear ring (1302) and the transmission gear (11) are separated, and the force block (18) will enter the docking groove (1306) on the docking sleeve (1303), and the pressure spring (1305) is used to provide auxiliary pressure; S4: When the output shaft of the servo motor (16) drives the transmission cylinder (1301) to rotate, the transmission cylinder (1301) will drive the force block (18) to rotate synchronously through the limit block (1304) and the docking sleeve (1303), and the force block (18) will drive the transmission rod (17) connected to the bottom to rotate, and the transmission rod (17) will drive the cam (19) to rotate. The cam (19) drives the moving frame (20) to move back and forth along the guide frame (32). At this time, the one-way toothed plates (21) on both sides of the moving frame (20) alternately drive the corresponding ratchet wheels (23) to rotate, so that the ratchet wheels (23) drive the corresponding winding wheels (26) to rotate through the control rod (25), so that the two winding wheels (26) can alternately pull the sanding belt (27). At this time, the moving sanding belt (27) can finely grind the wood surface. In addition, the user can also manually adjust it through the grip of the control rod (25).
