7. The polishing process of the aluminum profile surface polishing equipment according to claim 1, characterized in that: the process flow is as follows:

the first step is as follows: in an initial state, the slide block electromagnet is in a power-off state, the lifting slide block spring is in a relaxed state, the upper end surface of the polishing rotating block is attached to the upper end wall of the polishing cavity, the limiting slide block cavity is in a relaxed state, the bevel gear electromagnet is in a power-off state, the bevel gear spring is in a relaxed state, the driving bevel gear is meshed with the right sliding bevel gear, and the driving bevel gear is not meshed with the left sliding bevel gear;

the second step is that: placing the aluminum profile on a conveying wheel, pushing the aluminum profile leftwards, so that the aluminum profile moves leftwards to a position between a front limiting slide block and a rear limiting slide block, wherein the front conveying belt and the rear conveying belt are abutted to the front end face and the rear end face of the aluminum profile, a limiting slide block cavity is in a compressed state, the aluminum profile is clamped by the limiting slide blocks under the elastic action of the limiting slide block cavity through the conveying belt, the conveying belt can rotate through a conveying belt wheel, so that the aluminum profile can only move leftwards and rightwards, and when the left edge of the aluminum profile is positioned between a front contact switch and a rear contact switch, the contact switches are touched by the aluminum profile;

the third step: starting the slide block electromagnet, so that the slide block electromagnet electrically repels the magnetic lifting slide block, and further the magnetic lifting slide block overcomes the tension of a lifting slide block spring to move downwards, so that the polishing rotating block is driven to move downwards, and further the abrasive belt moves downwards to abut against the surface of the aluminum profile;

the fourth step: starting a grinding power motor, so that the grinding power motor rotates to drive a driving gear shaft to rotate, further, a driving gear rotates to drive a driven gear to rotate, further, a polishing rotating block is driven to rotate, and further, an abrasive belt is driven to rotate in the horizontal direction by taking the driven gear shaft as a center;
