[0003] For example, patent No. CN214817462U discloses a sanding belt machine with a sanding belt correction mechanism, including a base, a shell and a sanding belt body, the inner wall of one side of the shell is rotatably connected to a main rotating rod, the outer wall of one side of the shell is fixed with a motor by screws, the output shaft of the motor is connected to the main rotating rod through a coupling, the inner wall of one side of the shell is rotatably connected to a driven rotating rod, the three driven rotating rods and the main rotating rod form a rectangle, the three driven rotating rods are connected to the outer wall of the main rotating rod through the sanding belt body, and correction mechanisms are respectively provided on both sides of the outer wall of each driven rotating rod that contacts the sanding belt body, each group of correction mechanisms respectively includes an arc-shaped correction plate slidably connected to the outer wall of the driven rotating rod, two connecting rods and an electric telescopic rod, the electric telescopic rod is fixed to the inner wall of one side of the shell by screws, the two connecting rods are respectively fixed to the two sides of the outer wall of the arc-shaped correction plate by screws, the other sides of the two connecting rods are connected to the telescopic end of the electric telescopic rod, and the driven rotating rod is rotatably connected to the outer wall of the arc-shaped correction plate. The utility model is provided with three driven rotating rods and a main rotating rod, and the sanding belt body is arranged on the three driven rotating rods and the main rotating rod. The three driven rotating rods and the main rotating rod form a rectangle, which can increase the operating area and reduce the instability during use. A correction mechanism is respectively provided on both sides of each driven rotating rod, and an encoder that can realize the synchronous lifting and lowering of the electric telescopic rod is provided in the electric telescopic rod. Therefore, when the sanding belt body deviates, the arc-shaped correction plate and the electric telescopic rod can be used to adjust the sanding belt body at the same time or separately to move it straight and correct the sanding belt body to ensure its normal operation. However, during the use of the sanding belt machine, the workpiece is mostly placed directly on the grinding table for grinding. There is no correction mechanism on the sanding belt machine, and the position of the workpiece to be ground cannot be fixed, which causes the workpiece to be easily offset or dropped during the grinding process, thereby reducing the accuracy of the workpiece grinding.

There is no correction mechanism on the belt sander, and the position of the workpiece to be sanded cannot be fixed, which causes the workpiece to be easily offset or dropped during the sanding process, reducing the accuracy of the workpiece sanding. Therefore, a belt sander with an automatic correction mechanism can be designed. By sliding the limit blocks on both sides of the fixed block, the position of the fixed block can be unlocked by the limit blocks, so that the staff can use the fixed blocks to fix it according to the size of the sanding object, thereby improving the stability of the device. In the process of sanding, the fixed seat causes the second gear to deflect, and the servo motor drives the second gear to rotate the first gear, so that the device can automatically correct the fixed seat.
