Background technology
The even running of strip is an important topic of Treatment of Metal Surface production line electric control system always in the strip Treatment of Metal Surface production-line technique section drying oven; Color coating Wiring technology regulation strip surface did not allow to contact any roller before coating after the coating is not dried; In order to avoid the deface coating influences product quality; Therefore continuously strip is coated with in the drying oven at primary coat drying oven and face and must remains the nature overhang always, under the prerequisite that does not influence explained hereafter, allows slight fuctuation within a narrow range.
The control of strip degree of dangling is an important step of metal plate and belt coating line in the drying oven, and the excessive strip that means of sag is not enough at the stove internal tension, and strip is lax, the fire door that scratches easily, and it is undesired that serious words can cause whole lineman to do; Sag is too little, means that then strip tension force is too big in the stove, and serious words can cause tearing broken belt, perhaps influences the strip mechanical property and causes quality to reduce.Because line speed is very fast; Strip high-speed cruising in stove during the production line operation; And the drying oven body of heater is longer, and operating strip Chang Yinlu internal tension is unstable to fluctuate, when serious about the scratch air port in air channel in the stove of the strip of amplitude after can causing applying; Make and have influence on product quality by the strip surface tear; If avoid scratching and increase in the stove draught interval up and down, will strengthen consumption of heat energy like this, increase the cost of product.
The utility model content
The purpose of the utility model provides strip degree of dangling control system in a kind of Treatment of Metal Surface production line drying oven; It can detect the control that realizes strip integral body degree of dangling in the drying oven through the degree of dangling to the outer a certain point of strip of drying oven; Make the degree of dangling of strip in drying oven maintain near the setting value all the time; Overcome the prior art tabularium in the unmanageable problem of stove internal tension, realized the even running of strip in drying oven, improved product percent of pass.
The utility model solves the technical scheme that its technical problem adopted: metal plate and belt degree of dangling control system in the color coating line drying oven; Being coated with roller (1), metal plate and belt (2), drying oven (3), tensioning machine (4), ultrasonic ranging sensor (5), frequency converter (6), reductor (7) and variable-frequency motor (8) by face constitutes; Metal plate and belt (2) is coated with roller from face and comes out; Through drying oven (3), change tension force through the tensioning machine, be coated with roller (1) completion coating back through face and get into drying oven (3); And be connected with the tensioning machine (4) in drying oven (3) exit, the interior metal plate and belt of drying oven (3) (2) is the nature overhang.The metal plate and belt curve is consistent in drying oven (3) interior airduct air port curve and the stove.Ultrasonic ranging sensor (5) is measured the height change of dryer (3) exit metal plate and belt (2), and the real-time Simulation signal feedback is arrived frequency converter (6).The primary input signal of frequency converter (6) preestablishes according to the degree of dangling of metal plate and belt (2) and the mechanical property of the whole line equipment of production line; Form real-time control signal after signal that ultrasonic ranging sensor (5) feeds back and primary input signal relatively superpose and be transferred to variable-frequency motor (8).Tensioning machine (4) is made up of two idler rollers, and variable-frequency motor (8) through the speed discrepancy of two idler rollers of reductor (7) adjustment, is controlled strip tension force according to the real-time control signal of frequency converter (6) transmission.
The beneficial effect of the utility model is:
1. the utility model adopts the PID function of frequency converter, has to respond fast, easy to use, the easy characteristics of modification parameter, in practical application, can adjust in real time according to strip ruuning situation easily;
2. the utility model can have been avoided the generation of concussion at the normal strip degree of dangling of regulating fast and effectively in service of production line, realizes strip high speed, even running in the drying oven;
3. the utility model improves the qualification rate of product through the adjustment optimization and improvement control accuracy of parameter, has improved economic benefit of enterprises.
