The working process of the plate automatic edge banding machine of the present embodiment:

First, the boards enter the first conveyor 101. Generally, adjacent boards are close together. When the boards enter the second conveyor 102, the first visual sensor 105 of the second conveyor 102 senses The entry of the plate sends a signal to the control system of the second conveyor 102, and the control system of the second conveyor 102 sends an instruction to cause the second conveyor 102 to produce an instantaneous acceleration, open the interval between two adjacent plates, and enter the The plate of the second conveyor 102 enters the edge banding station;

Then, the edge banding mechanisms on both sides of the second conveyor 102 perform edge banding work on the board: when the edge banding mechanism 2 starts to work, place the three rolls of adhesive tape on the three tape fixing rollers 202 respectively, and place the tape head in the marking area In 209, the tape head of the conveyor belt close to the second conveyor 102 is pulled to the end of the first plate along the I-shaped roller 401, the elastic roller 402 and the pressing roller 403, and then the plate conveyor 1 starts Work, the adhesive tape seals the edges on both sides of the plate under the limits of the I-shaped roller 401, the elastic roller 402 and the pressing roller 403. When the first roll of tape is used up, the first drive motor 207 works to drive The connecting frame 204 rotates, the second roll of adhesive tape rotates to the position of the first roll of adhesive tape, and the first roll of adhesive tape rotates to the position of the third roll of adhesive tape. Because the adhesive tape is sticky, the traction part of the first roll of tape sticks to the roll end of the second roll of tape, driving the second roll of tape to pull, the second cylinder 3011 of the first cutting device 301 works, and the piston rod extends Drive the first cutter 3012 to cut off the traction part of the first roll of tape. When the second roll of tape is almost used up, the third roll of tape will continue to be added, so there is no need to frequently replenish tape during edge banding, which improves the automation of work Efficiency, when the edge banding work is completed on both sides of the board, the second visual sensor 303 senses the gap between two adjacent boards, the second drive motor 3021 works, and the drive shaft of the second drive motor 3021 drives the cutting machine through the crank arm 3022 The knife guide bar 3023 stretches out so that the second cutter 3025 cuts off the adhesive tape.

The function of the I-shaped roller 401, the elastic roller 402 and the pressing roller 403 is that the I-shaped roller 401 is mainly used for traction and positioning of the adhesive tape, and the elastic roller 402 is used for pressing the adhesive tape on the side wall of the board. The joint roller 403 is used to attach the upper and lower sides of the tape to the upper and lower sides of the plate.
