[0002] A sliding table saw, also known as a panel saw or precision panel saw, is a woodworking machine widely used in furniture manufacturing, wood processing, building decoration and other industries. It is mainly used for efficient and accurate sawing of various boards. The existing feeding mechanism of the sliding table saw places the board on the slide, and the motor drive module drives the slide to move, so that the slide pushes the board to move, thereby feeding the sliding table saw. However, during the operation of the sliding table saw, the vibration of the sliding table saw may cause the board to slide between the slide and the slide, causing the board to deviate.

[0003] For example, the utility model with announcement number CN213766211U discloses a feeding mechanism of a sliding table saw, including a guide rail, a slide seat, a mounting block, a clamping bolt, a mounting frame, a support pulley, and a feeding drive mechanism. The feeding drive mechanism includes a threaded slider, a servo motor, a reducer, a screw shaft, and a screw. The guide rails are grouped and installed symmetrically on the left and right, the slide seats are grouped and installed on the guide rails, the mounting block is rigidly installed on the upper end surface of the slide seat, the clamping bolt is installed on the upper end surface of the mounting block, the mounting frame is rigidly installed at the front end position between the symmetrically installed guide rails, the support pulley is rigidly installed at the rear end position of the upper end surface of the guide rail through the wheel seat, the threaded slider is rigidly installed at the middle position of the lower end surface of the mounting block, and the threaded slider It is installed in conjunction with the screw, the screw is rigidly installed at the power output end of the reducer, the power input end of the reducer is rigidly connected to the power output shaft of the servo motor, the reducer is fixed to the servo motor housing through the reducer bracket, and the servo motor is rigidly installed at the center position of the front end face of the mounting frame through the motor bracket. In the technical solution of this patent, the screw is driven by the servo motor to rotate, so that the slide slides on the guide rail, and then the slide pushes the plate to move, thereby realizing the feeding of the sliding table saw. However, vibration will occur during the operation of the sliding table saw.
