Description
Technical field
The utility model belongs to the equipment of a kind of coating layer thickness control in the coating metal board assembly line, the dedicated control system of the stepless control of particularly a kind of aluminium strip coating layer thickness.
Background technology
As shown in fig. 1, the coating layer thickness decisive factor in the existing coating layer aluminium plate production line is: 1, the operating forward upper surface of treating coated aluminum plate 1, with T time of contact on the surface of last applicator roll 22 own stickness paints in the immediate rotation; 2, by the coating content G that material roller 21 is supplied with applicator rolls 22 surfaces that is stained with of its surface tangent and backwards rotation with applicator roll 22 surface.T is increased to when quite abundant when time of contact, and the coating content G that supplies with the applicator roll surface just becomes the leading factor of decision coating layer thickness.And coating content G is closely related with the velocity of rotation separately of being stained with material roller and applicator roll.
The velocity of rotation separately of being stained with material roller and applicator roll in the existing coating layer aluminium plate production line is coupling in the velocity of rotation of the motor of being stained with material roller and applicator roll just; Those of ordinary skill in the art knows, be coupling in the specified velocity of rotation of the motor of being stained with material roller and applicator roll normally make dispatch from the factory the back just changeless.Therefore, when treating that speed that coated aluminum plate moves forward is enough slow, time of contact, T was increased to when quite abundant, and the coating layer thickness that determines in the velocity of rotation of the motor of being stained with material roller and applicator roll is difficult to change by being coupling.Remedial measure is by rule of thumb through adjusting upward the position of backing roll 25; Reach the gap length between the operating surface of treating the upper surface of coated aluminum plate 1 and the last applicator roll 22 own stickness paints in the immediate rotation of adjustment; With control coating layer thickness what; This remedial measure is difficult to reach the accurate coating layer thickness of expectation on the one hand, and its coating layer thickness adjustment amount is limited after all on the other hand.
This shows that it is simple and easy to study and design a kind of operation, can realize that the dedicated control system of the stepless adjustable stepless control of aluminium strip coating layer thickness of coating layer thickness digitlization is necessary.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and it is simple and easy to study and design a kind of operation, can realize the dedicated control system of the stepless adjustable stepless control of aluminium strip coating layer thickness of coating layer thickness digitlization.
The purpose of the utility model is achieved in that
The dedicated control system of the stepless control of a kind of aluminium strip coating layer thickness, comprise be matched with operating forward treat coated aluminum plate be stained with the coating system that material roller and upper and lower backing roll are formed by upper and lower applicator roll and upper and lower; Be matched with the electric control system of coating system: comprise the motor that is coupling and is stained with material roller and upper and lower applicator roll in upper and lower; Be connected in power switch, the power supply/voltage dial gauge of the electrical control cabinet of said motor; Each motor run indicator; The systems soft ware of system hardware that the KM1-KM4 A.C. contactor that is used to start the QF1-QF4 automatic citrcuit bearker of each motor and cooperates is with it formed and the common mode of connection composition that is connected aforementioned system hardware; It is characterized in that also being designed with PLC programmable controller (programmable controller) in the electrical control cabinet of electric control system system hardware; Be matched with the TP touch-screen (Touchpanel) of programmable controller internal processes; Receive 4 BP1-BP4BP variable-frequency governors (frequencychanger/frequency converter) of programmable controller internal processes control, be series at 4 KA1-KA4 relays and the transformer between programmable controller and the automatic citrcuit bearker, the dc source that rectifier constitutes; Electric control system software also is designed with through programmable controller by the touch-screen setting, through programmable controller internal processes and the touch-screen text of variable-frequency governor to being coupling and carrying out the stepless control of digitlization respectively in upper and lower velocity of rotation of being stained with the motor of material roller and upper and lower applicator roll.
In described programmable controller internal processes and the touch-screen text; Treating under the prerequisite that speed that coated aluminum plate moves is forward confirmed; According to the velocity of rotation value and corresponding coating layer thickness that are coupling and are stained with the motor of material roller and upper and lower applicator roll, utilize the programmable controller internal processes that the touch-screen text is demarcated in upper and lower through the variable-frequency governor adjustment.
The dedicated control system of the stepless control of aluminium strip coating layer thickness that the utility model enforcement obtains, shown following beneficial effect through trying out: 1, operation is simple and easy.Operating personnel only need set the velocity of rotation value and corresponding coating layer thickness value of required motor through the coating layer thickness text that touch-screen has been demarcated, and just can produce the coating layer aluminium plate of respective thickness.2, realized that the coating layer thickness digitlization is stepless adjustable.Stepless control is through programmable controller to the utility model to the aluminium strip coating layer thickness; Stand the variable-frequency governor of programmable controller internal processes control by touch-screen; Carry out the stepless control of digitlization to being coupling respectively in upper and lower velocity of rotation of being stained with the motor of material roller and upper and lower applicator roll and realize, need not like the described position of passing through the adjustment backing roll by rule of thumb of prior art with the control coating layer thickness.
