Adhesive glue is provided on the side surface of the pinch roller 21, which can temporarily fix the edge band 23 on it, but the bonding strength is much lower than that between the edge band 23 and the plate 100. strength, so when the pressure roller 21 presses the edge band 23 onto the side 110 to be sealed, the edge band 23 will fit on the side 110 to be sealed, and Disengage from the pinch roller 21 simultaneously. The edge band 23 is circumscribed on the pinch wheel 21 and the take-up wheel 22, the outer side of the edge band 23 is attached to the pinch wheel 21, and its inner side can be positioned with the The tangent position of the side edge 110 of the board to be edged. When the edge band 23 is attached to the board 100 along the direction in which the pinch wheel 21 rotates, the take-up wheel 22 is also pulled by the edge band 23 to rotate at the same time. When the edge sealing is completed, the pinch roller 21 stops rotating and stops pushing out the edge sealing belt 23, and the edge sealing belt 23 also stops pulling the winding wheel 22 and stops rotating, so that all The release and retreat of the pinch wheel 21 are synchronized with the supply and stop of the tape supply of the take-up wheel 22 to ensure better synchronization.

2. As the sheet material 100 moves, the start sensing unit 41 senses and recognizes the front end of the sheet material 100, simultaneously starts the pinch wheel 21 and controls the entrainment unit 24 to open, and starts the edge banding process;

3. In the edge banding process, the pinch wheel 21 is pressed against the side 110 to be edge banded, and the winding wheel 22 rotates with the pinch wheel 21 to supply the edge band 23. At this time , the glue discharging unit is also under the control of the controller 50 , and the glue is discharged through the glue outlet 25 while the pinch wheel 21 is rotating.

4. When the plate 100 moves to complete the edge banding, the end of the plate 100 moves to the position corresponding to the tape cutting knife 31, and the termination sensing unit 42 transmits the position sensing signal to the control module 50, so The controller 50 controls the taping mechanism 20 to stop operating, which includes stopping the rotation of the pinch wheel 21 , stopping the glue discharging by the glue discharging unit, and clamping the edge banding 23 by the entraining unit 24 . At this time, the tape cutting mechanism 30 receives the start signal from the controller 50 , controls and starts the tape cutting knife driving motor 32 to make the tape cutting knife 31 cut off the edge band 23 .
