The use method of the board cutting machine with the edge grinding function for the gypsum board production line comprises the following steps:
step one, guiding and straightening gypsum boards:
the gypsum board that the production line conveying was come enters into the link, then enters into the leading truck inside, because preceding, the rear end face of leading truck is the arc form, and has arranged the leading wheel, therefore the gypsum board can easily accomplish the direction and put right, enters into right-hand member carriage inside, and the distance between the both sides leading wheel periphery is the same with the gypsum board width around the right-hand member carriage.
When the gypsum board passes through the lower part of the roller, the roller is driven to rotate, the angular displacement sensor is driven to rotate by the rotation of the roller, and the angle value detected by the angular displacement sensor is converted into the length of the gypsum board moving to the left by the control device;
step two, cutting off the gypsum board:
firstly, the gypsum board coming off the production line is conveyed to a left end conveying frame, then three angular displacement sensors are started, when the gypsum board movement values detected by at least two of the three angular displacement sensors are the same, when the set value is reached, the control device controls the oil pump and the electromagnetic valve I to be opened, the oil pump pumps the hydraulic oil in the oil tank into the hydraulic cylinder through the oil inlet pipe to push the piston to move downwards, so that the upper end plate pushes the pressing plate to move downwards, when the touch plate on the pressing plate touches the limit switch III, the pressing plate is just contacted with the upper end surface of the gypsum board, the limit switch III transmits a signal to the control device, the control device controls the motor to rotate, the hydraulic cylinder, the upper end plate and the lower end plate are driven to move leftwards together through the screw and the fixed connecting rod, and the moving speed of the hydraulic cylinder, the upper end plate and the lower end plate is the same as the advancing speed of the gypsum board.
The piston continuously moves downwards, after the gypsum board is clamped by the pressing plate and the lower end plate, the pressing plate does not continuously move downwards, the upper end plate compresses the thrust spring I to push the knife switch to continuously move downwards to cut off the gypsum board, and at the moment, the displacement plate moves upwards in the displacement hole;
step three, edging the end face of the gypsum board:
after the knife switch cuts off the gypsum board, open solenoid valve III, inside hydraulic oil of hydraulic pressure chamber entered into the oil tank through middle oil return pipe, and the pressure-regulating valve on the middle oil return pipe has injectd the hydraulic pressure of hydraulic pressure intracavity portion, and the hydraulic pressure of hydraulic pressure intracavity portion reduces this moment, and the piston shifts up under thrust spring III promotes until the displacement board removes the lower extreme in displacement hole.
Meanwhile, the oil pressure in the middle oil return pipe between the two pressure regulating valves is gradually increased, the elastic bag is extruded, the elastic bag is extended to touch a touch switch, the touch switch transmits a signal to the control device, the control device controls the motor I to be started, the motor I drives the screw rod I to rotate, a push block in threaded connection with the screw rod I moves backwards on the screw rod I, and then the slide block drives the grinding piece to move backwards, so that the gypsum board notch is ground to be flat;
fourthly, resetting the grinding plate:
when the push block slides to the rear end of the push block cavity to be in contact with the limit switch II, the limit switch II transmits a signal to the control device, the control device controls the motor I to rotate reversely, the push block drives the sliding block to move forwards, when the push block collides with the limit switch I, the limit switch I transmits the signal to the control device, and the control device controls the motor I to stop rotating;
step five, resetting the upper end plate:
after the abrasive disc resets, controlling means control solenoid valve II and solenoid valve IV open, solenoid valve III closes, the motor reversal, and the hydraulic pressure chamber is direct to be connected with the oil tank through-going, and the piston moves topmost under thrust spring III's promotion, and the inside hydraulic oil of middle oil return pipe between with two air-vent valves is discharged to the pressure release pipe, and the screw rod passes through fixed connection pole and removes pneumatic cylinder and lower end plate to middle control chamber rightmost end.
Compared with the prior art, the invention has the following beneficial effects:
(1) the advancing length of the gypsum board is detected through the three angular displacement sensors, and the length measurement of the gypsum board is accurate.
(2) Before using the plug-in strip to cut off the gypsum board, the clamp plate presss from both sides the gypsum board on incision both sides tightly with the lower end plate, and when the plug-in strip cutting like this, the gypsum board can not the perk, and the lower part also has the support, and the effectual gypsum board incision of having guaranteed levels.
(3) Can polish the incision after cutting the gypsum board, simplify the process steps in the gypsum board production later stage, reduction in production cost.
