[0023] (2) The composite paddle blade preparation device is provided with a fixing component. During the preparation of the paddle blade, in order to facilitate the surface of the paddle blade to fully contact the grinding disc, it is necessary to adjust the support height of the lifting plate on the paddle blade.

[0024] (3) The composite paddle blade preparation device is provided with a chip blowing assembly. When the grinding disc is used to grind the blade, a large amount of waste chips are easily generated. When the sleeve block moves, the sleeve block will move with the side plate, prompting the side plate to move with the push pin, prompting the push pin to squeeze the rubber block, causing the rubber block to compress the air inside the sealing tube, so that the gas is discharged from the exhaust head through the exhaust pipe, so that the gas can blow away the waste chips generated during the grinding process, thereby improving the processing accuracy of the device for blade preparation.

[0044] A method for preparing a composite paddle blade comprises the following steps:
[0045] S1. First, the paddle body 3220 is fixedly mounted on the top of the supporting platform 3212;
[0046] S2. Next, the height of the grinding disc 3117 is adjusted, and the grinding disc 3117 is made to fit the surface of the paddle body 3220;
[0047] S3, then the surface of the paddle body 3220 is evenly polished by the polishing disc 3117;
[0048] S4, turning on the motor 322 to rotate the screw rod 323, so that the paddle body 3220 moves, so as to adjust the grinding position of the paddle body 3220;
[0049] S5. Finally, the gas is exhausted through the exhaust head 337 to blow away the waste chips generated during grinding, thereby completing the preparation of the paddle body 3220.
[0050] Working principle: during the preparation of the paddle blades, the surface of the paddle blades needs to be polished to remove the burrs generated on the surface of the blades during the preparation process. At this time, the operator can turn on the motor 312 to cause the output shaft 313 to rotate. During the rotation of the output shaft 313, the gear 314 will rotate. During the rotation of the gear 314, it will mesh with the rack 315, causing the rack 315 to move up and down. During the up and down movement of the rack 315, the rectangular frame 3111 will move up and down through the connecting block 316 to adjust the height of the blade surface polishing. During the up and down movement of the connecting block 316, the limit block 317 will move with it. During the downward movement of the connecting block 316, the limit block 317 will slide downward along the outer wall of the limit column 318, causing the limit The positioning block 317 compresses the spring 1 3110, so that the spring 1 3110 can buffer the connection block 1 316, the limiting block 317 and the rectangular frame 3111 during the up and down movement. After the grinding height of the blade is determined, the operator can turn on the motor 2 3115 to cause the output shaft 2 3116 to rotate. During the rotation of the output shaft 2 3116, the grinding disc 3117 will rotate. During the rotation of the grinding disc 3117, the surface of the blade can be polished and deburred. During the grinding of the blade surface, the operator can turn on the electric push rod 3112 to cause the slider 3113 to move inside the rectangular frame 3111, thereby causing the grinding disc 3117 to move, so as to grind different positions on the surface of the blade, thereby preparing the blade.
[0051] In the process of preparing the blade, in order to facilitate the surface of the blade to fully contact the grinding disc 3117, it is necessary to adjust the support height of the lifting plate 327 for the blade. At this time, the operator can press the extrusion block 3210 to cause the extrusion block 3210 to squeeze the spring 2 329, so that the extrusion block 3210 moves with the insertion rod 3211, so that the insertion rod 3211 is separated from the limit of the U-shaped top plate 326, and then the surface of the blade is adjusted by moving the height of the lifting plate 327. After the lifting height of the lifting plate 327 is adjusted, the operator can release the squeezing block 3210, and the plug rod 3211 will be reset under the reaction of the spring 2 329, so that the plug rod 3211 is inserted into the side inner wall of the U-shaped top plate 326, thereby fixing the position of the lifting plate 327. When grinding the blade, the operator can turn on the motor 322 to cause the screw rod 323 to rotate. The sleeve block 324 will move, prompting the support block 325 and the U-shaped top plate 326 to move, so that the grinding position of the blade can be adjusted. In the process of preparing the blade, in order to avoid the blade shaking during the grinding process, the blade needs to be clamped and fixed. The operator can place the blade on the top of the carrier 3212, and then tighten the rotating block 3218 to prompt the screw 3217 to rotate. After the screw 3217 rotates, The clamping block 3219 is moved downward to clamp and fix the blade, thereby improving the stability of the blade during grinding. When the blade needs to be tilted for grinding, the operator can flip the support plate 3213, then rotate the support platform 3212 to a suitable angle, and then clamp the support plate 3213 into the side wall of the clamping block 3214, thereby tilting the support platform 3212, which is convenient for the operator to grind the blade through the grinding disc 3117.
[0052] When the grinding disc 3117 is grinding the blade, a lot of waste chips are easily generated. When the sleeve block 324 moves, the sleeve block 324 will move with the side plate 331, prompting the side plate 331 to move with the push pin 332, prompting the push pin 332 to squeeze the rubber block 333, so that the rubber block 333 compresses the air inside the sealing tube 334, and the gas is discharged from the exhaust head 337 through the exhaust pipe 336, so that the gas can blow away the waste chips generated in the grinding process, thereby improving the processing accuracy of the device for blade preparation.
