(2) And starting to cut the edge banding band of the workpiece plate. And the workpiece plate enters the front and rear cutting devices of the edge sealing belt under the conveying of the conveyor belt of the edge sealing machine. The front end of the plate impacts the front cutting profiling 23 of the front cutting sawing mechanism, and at the moment, the control unit controls the Y21 coil of the first electromagnetic valve V1 and the Y23 coil of the second electromagnetic valve to be electrified. The gas in the total gas pipe of the edge bonding machine enters the third interface of the first electromagnetic valve V1 through the first pressure regulating valve P1 and the second pressure regulating valve P2, then enters the rod cavity of the front cutting cylinder 3 through the second interface of the first electromagnetic valve V1, the gas flowing out of the rodless cavity of the front cutting cylinder 3 enters the first interface of the second electromagnetic valve V2, then flows into the fourth pressure regulating valve P4 through the fourth interface of the second electromagnetic valve V2, is discharged from the fourth pressure regulating valve P4, the piston rod of the front cutting cylinder 3 starts to shrink, and drives the front cutting sawing mechanism to move downwards along the linear guide rail, and when the front cutting sawing mechanism moves downwards, the horizontal component speed of the falling speed of the front cutting sawing mechanism is consistent with the moving speed of the plate.
(3) Along with the continuous feeding of the plate, the front cutting profiling 23 moves downwards along the linear guide rail under the action of the thrust of the plate and the front cutting cylinder, and the front cutting profiling 23 completes the sawing of the edge sealing belt. When the edge sealing belt is cut off, the control unit controls the Y21 coil of the first electromagnetic valve V1 to be powered on, the Y23 coil of the second electromagnetic valve V2 is powered off, and the valve core of the first electromagnetic valve V1 is still located at the left side position. At this time, the gas in the total gas pipe of the edge banding machine enters the third interface of the first electromagnetic valve V1 through the first pressure regulating valve P1 and the second pressure regulating valve P2, then enters the rod cavity of the front cutting cylinder 3 through the second interface of the first electromagnetic valve V1, the gas flowing out of the rodless cavity of the front cutting cylinder 3 enters the first interface of the second electromagnetic valve V2, then flows into the fourth interface of the first electromagnetic valve V1 through the second interface of the second electromagnetic valve V2, then flows into the silencer from the first interface of the first electromagnetic valve V1, is discharged from the silencer, and the piston rod of the front cutting cylinder 3 continues to shrink to drive the front cutting sawing mechanism to accelerate to leave until the piston reaches the fixed position of the first position sensor 5.
(4) When the piston of the front cut cylinder 3 reaches the first position, the control unit controls the Y21 coil of the first electromagnetic valve V1 to be powered off, and the Y21 coil is powered off to enable the Y25 coil to be powered on instantaneously.

(5) When the plate is about to be separated from the front cutting device and the rear cutting device of the sealing side band, the control unit controls the Y31 coil of the third electromagnetic valve V3 to be electrified. At this time, the gas in the total gas pipe of the edge banding machine enters the third interface of the third electromagnetic valve V3 through the third pressure regulating valve P3, flows out from the second interface of the third electromagnetic valve V3, the flowing gas enters the rod cavity of the back cutting cylinder 4, then flows into the fourth interface of the third electromagnetic valve V3 from the rodless cavity of the back cutting cylinder 4, then flows into the silencer from the first interface of the third electromagnetic valve V3, is discharged from the silencer, the piston rod of the back cutting cylinder 4 contracts, drives the back cutting sawing mechanism to slide downwards, and the back cutting explorator 32 performs sawing processing on the edge banding band at the tail part of the plate.
