[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] like Figure 1-Figure 10 The green spraying pre-treatment equipment for aluminum profiles shown in the figure comprises a tabletop 1, a bottom frame 32 fixedly connected to the lower surface of the tabletop 1, a notch 2 is penetrated through one side of the upper surface of the tabletop 1, a fixing frame 3 is fixedly installed on the inner side of the notch 2, a long shaft 6 is rotatably installed on the inner top surface and the inner bottom surface of the fixing frame 3, and a short shaft 5 is rotatably installed on the two inner walls of the fixing frame 3 through a driving mechanism, and two symmetrical grinding blocks 11 are fixedly installed at the ends of the outer surfaces of the long shaft 6 and the short shaft 5, respectively, and grinding plates 13 and protruding blocks 12 are extended from the upper and lower ends of the side surfaces of the grinding blocks 11, and square blocks 14 are extended from the lower ends of the sides of the grinding blocks 11, and the end faces of the square blocks 14 on both sides are in contact with each other. The specific structure can be referred to Figure 6 , Figure 7 As shown, two symmetrical grinding columns 26 are respectively arranged behind the upper and lower long shafts 6 through a transmission mechanism, and a curved groove 27 is opened on the outer surface of the grinding column 26. A guiding mechanism is arranged on the upper surface of the table 1 and near the rear of the notch 2;

[0031] Grinding, such as Figure 8 , Fig. 9 , Fig.10 As shown, the aluminum profile 33 passes through the inner side of the fixed frame 3, the grinding block 11, the protruding block 12, and the square block 14 together grind the inner wall of the groove 34, the grinding plate 13 grinds the outer surface of the aluminum profile 33, and the curved groove 27 grinds the corners of the aluminum profile 33.

[0032] like Figure 4 As shown, the driving mechanism includes a motor 18 fixedly mounted on the outer surface of the fixed frame 3, and the ends of the long shaft 6 and the short shaft 5 rotate and penetrate the inner wall of the fixed frame 3, and the ends of the long shaft 6 and the short shaft 5 are respectively fixedly connected to the output shaft of the motor 18. The long shaft 6 or the short shaft 5 is driven by the motor 18 to rotate.

[0033] like Figure 5 , Figure 6 and Figure 7As shown, the outer surface ends of the long axis 6 and the short axis 5 are respectively provided with semi-column openings 7, the inner side of the semi-column openings 7 is fixedly embedded with a mounting block 8, the two sides of the semi-column openings 7 and the mounting block 8 are respectively provided with mounting grooves 16, the inner side of the mounting grooves 16 is fixedly provided with mounting posts 17, the outer surface of the grinding block 11 is penetrated with mounting holes 15, one side of the grinding block 11 is inserted into the inner side of the mounting groove 16, and the mounting posts 17 are slidably inserted into the inner side of the mounting holes 15. The mounting posts 17 play a positioning role to prevent the grinding block 11 from sliding down along the inner side of the mounting groove 16 and detaching after clamping.

[0034] The outer surface of the mounting block 8 is slidably penetrated with a mounting bolt 9, one end of which is slidably penetrated through the inner surface of the semi-column opening 7 and a mounting nut 10 is threadedly sleeved on the end. Installation and disassembly are convenient, and can be completed with the help of tools such as wrenches.

[0035] like Figure 2 , Figure 3 As shown, mounting frames 4 are fixedly connected to both sides of the lower surface of the fixing frame 3, and the front and rear ends of the upper surface of the mounting frame 4 are fixedly connected to the lower surface of the table 1. This is used to ensure the stable installation of the fixing frame 3.

A retaining frame 24 is fixedly mounted on the inner wall of the protective cover 28. The retaining frame 24 is rotatably sleeved on the ends of the two grinding shafts 25 and the rear end of the driven shaft 21. The transmission bevel gear 23 at the rear end of the driven shaft 21 is meshed with the transmission bevel gear 23 at the end of the grinding shaft 25.

The inclined guide plates 31 on both sides can guide the feeding of the aluminum profile 33, and the limit rollers 30 on both sides play a role in guiding the aluminum profile 33 to be transported forward.

[0039] During grinding, the user passes the aluminum profile 33 between the limiting rollers 30 on both sides and guides it to push forward. As the pushing progresses, the grinding block 11 will move relatively to the inside of the notch 34, the grinding plate 13 contacts the outer surface of the aluminum profile 33, the protruding block 12 contacts the inner walls of the notch 34 on both sides, and the square block 14 contacts the inner bottom surface of the notch 34. Figure 8 , Fig. 9 and Fig.10 As shown, as the motor 18 runs, the inner wall of the slot 34 will be polished, and as the aluminum profile 33 moves forward, the inner wall of the slot 34 and the surface of the aluminum profile 33 can be fully polished, and the polishing is more comprehensive and more efficient.

[0040] During grinding, when the motor 18 is running, the long shaft 6 rotates, and the active bevel gear 19 transmits the transmission to the driven bevel gear 20, so that the driven shaft 21 rotates, and under the action of the transmission bevel gear 23, the grinding shafts 25 on both sides rotate, and then the grinding column 26 rotates, and the corner position of the aluminum profile 33 is ground by rotating the curved groove 27. Therefore, this solution can perform comprehensive grinding in the one-time advancement of the aluminum profile 33, effectively improving the processing efficiency.

[0041] The user can remove the mounting block 8 by unscrewing the mounting nut 10, and then remove the grinding block 11, which is convenient for later maintenance and replacement and ensures the grinding effect.
