Abstract
The invention relates to an aluminum processing device, in particular to a device for controlling the drapability of aluminum strips on a color coating production line of the aluminum strips. The device comprises the aluminum strips wound on a roll system. The aluminum strips pass through a drying box, a laser range finder used for detecting the drapability distance of the aluminum strips is arranged on an inlet of the drying box, and the laser range finder is connected onto a PID controller. The PID controller is connected onto a motor speed regulation device, the motor speed regulation device is connected onto a motor, and the motor drives a tensioning roll located in the roll system to rotate. The device can monitor the drapability of the aluminum strips in real time and adjust the drapability timely.
Description
Technical field
The present invention relates to a kind of aluminium process equipment, specifically a kind of on aluminum strip color coating line to the device that the pendency degree of aluminum strip controls.
Background technology
Aluminum strip color-coating line is the special complete equipment in aluminium processing industry, aluminium surface being carried out to deep processing process, its color coated aluminum plate produced greatly can improve weatherability, the corrosion resistivity of aluminum strip, and can application be shades of colour, add the decorate properties of aluminum strip.
Aluminium sheet is after the rolling of cold-rolling mill, become the aluminum strip of 0.2-0.5 mm, then pass through: material loading, (alkali cleaning washing), (pickling washing), (extracting oven dry), chromaking baking, paint spraying, high-temperature baking, air-cooled, waxing, blanking, finished product are stacked and formed final products.
But existing equipment can not be monitored the pendency degree of aluminum strip and regulate and control, and causes aluminum strip easily to occur abrasive situation in process of production, and cause aluminum strip cured effect in drying baker undesirable.
summary of the invention
Technical matters to be solved by this invention is, provide a kind of can the pendency degree of Real-Time Monitoring aluminum strip, and the aluminum strip color-coating line pendency degree control device that adjusts can be given in time.
Aluminum strip color-coating line pendency degree control device of the present invention, comprise the aluminum strip fastened around roller, described aluminum strip is through a drying baker, be provided with a laser range finder detected the pendency distance of aluminum strip in the porch of described drying baker, described laser range finder is connected to PID controller; Described PID controller is connected to motor speed control device, and described motor speed control device is connected to motor, and in described motor driven roller system, idler roller rotates.
Described motor speed control device is DC motor drive, and described motor is direct current generator.
Described motor via reducer drives idler roller to rotate.
The invention has the advantages that: by laser range finder, Real-time Collection is carried out to the signal of the aluminum strip of drying baker porch, carry out PID computational analysis simultaneously, compensate according to the speed of actual linear velocity offset value calculation to idler roller, the tensile force of adjustment aluminum strip, namely reaches the object of adjustment aluminum strip pendency degree.Improve the cured effect of aluminum strip in drying baker, and according to aluminum strip scratch situation on a production line, suitable adjustment can be carried out to control system, improve the total quality of product.
The present invention solves the problem of aluminum strip shake well, stabilizes the Tension Distribution of aluminum strip in acceleration and deceleration process, stabilizes tension force completely, improves the stability of system.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present invention.
Embodiment
?below in conjunction with the drawings and specific embodiments, the present invention is described further
As shown in the figure: a kind of aluminum strip color-coating line pendency degree control device, comprise the aluminum strip 1 fastened around roller, described aluminum strip 1 is through a drying baker 2, a laser range finder 4 that the pendency distance of aluminum strip 1 is detected is provided with in the porch of described drying baker 2, described laser range finder 4 is connected to PID controller 5, and by the signal transmission of aluminum strip that collects to PID controller 5.PID controller carries out computational analysis.Described PID controller is connected to DC motor drive.
To the regulated quantity that DC motor drive input reference amount and PID controller calculate.
Described DC motor drive is connected to direct current generator, the rotating speed of adjustment direct current generator.In described DC motor Driver roller system, idler roller 3 rotates.When the velocity variations of idler roller 3, aluminum strip 1 degree of pendency also will change, and in aluminum strip 1, the size direction of each point tension force all changes.Stablizing of the pendency degree of regulating guarantee aluminum strip 1 in drying baker 2.
