[0029] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3:

[0030] A tracking chamfering device for an edge banding machine includes a base plate 1. A transverse guide rail 2 is provided above the base plate 1, and a slider 3 slides along the transverse guide rail 2. A slide plate 4 is fixedly mounted on the slider 3. A transverse rack 5 is provided below the base plate 1. A motor 6 is fixedly mounted below the slide plate 4 and located below the base plate 1. A gear 7 on the shaft of the motor 6 meshes with the transverse rack 5. A vertical optical axis 8 and a support strip 9 are provided above the base plate 1. A slide block 10 slides along the vertical optical axis 8, and a vertical rack 11 is provided on one side of the slide block 10. The bracket 9 is equipped with a second motor 12.

A cylinder 19 is mounted on one of the mounting plates 15. The piston of the cylinder 19 is connected to the slide 10.

[0031] The working principle of this utility model is as follows: Figure 1-3As shown, the rotation of the shaft of motor 6 drives the rotation of gear 7, thereby causing the slide plate 4 to move laterally, following the movement of the wooden board; the rotation of the shaft of motor 12 drives the rotation of gear 13, thereby causing the slide block 10 to move vertically; the piston rod of cylinder 19 moves, causing the connecting plate 16 to move longitudinally, thereby causing motor 17 and the tracking blade 18 to move longitudinally. The rotation of the shaft of motor 17 drives the tracking blade 18 to rotate, thus achieving chamfering. This utility model first chamfers the lower front corner of the wooden board, then the upper front corner, then the upper rear corner, and finally the lower rear corner.
