Description
One, technical field:
The utility model relates to a kind of full A/C transmission control rewinding machine.
Two, background technology:
In current paper-making process, the driving system of rewinding machinery adopts Direct Current Governor System mostly, i.e. forward and backward bottom roller and move back paper bowl three mair motor and all adopt DC drive system.The reason of DC drive system is adopted first to be that Direct Current Governor System develops the earliest, technology maturation, particularly move back the mode of operation that the requirement of paper bowl motor is in speed control by constant power in whole operation interval, move back paper bowl power of motor like this and select according to the maximum power required for whole equipment.Such as, the tensile requirements of certain rewinding machine calculates 1 kilograms per centimeter by fabric width, supposes that fabric width is 400 centimetres, then view picture tension requirements is 400 kilograms, suppose that the operation speed of machine of requirement is 1000 ms/min again, then tension force power demand is 67 kilowatts, and Here it is moves back the horsepower rating of paper bowl motor.When the DC machine of selection 67 kilowatts, if 1:5 when moving back the diameter variation range of paper roll, select the weak-magnetic speed-regulating range of DC machine to be more than 1:5 so again, then the power of motor moving back paper bowl is exactly 67 kilowatts in theory.
But DC motor apparatus is clumsy, and cost is high, and particularly fault rate is high, difficult in maintenance.In electric machine speed regulation field, the development of A/C transmission control particularly performance-oriented Alternating Current Governor System is later than DC drive system, so occupy an leading position at performance-oriented speed control field DC drive system always.After the end of the seventies in last century, alternating-current actuating system had breakthrough in High Performance speed control, AC electrical machine equipment is simple, cost is low, safeguard that the advantages such as letter highlight, particularly also has feature that is energy-conservation and reduction resource consumption, alternating-current actuating system captures leading position at electric machine speed regulation control field rapidly, instead of DC drive system.
But, because the fatal defects of alternating-current actuating system when the transmission controlling rewinding machine and particularly move back paper bowl controls is that the weak magnetic scope of alternating-current motor/AC motor is too little.Due in history and design, alternating current dynamo is typically designed as power frequency 50HZ and rated voltage 380v, and when for weak-magnetic speed-regulating, usual frequency of operation is no more than 100hz.Therefore, the scope of weak-magnetic speed-regulating is exactly 1:2 in theory, and like this in order to meet the demand of rewinding machine paper bowl motor, (demand of the weak magnetic scope 1:5 that as above illustrates) just can only improve the power of alternating-current motor/AC motor to make up the shortcoming of weak magnetic scope deficiency.So just make the rewinding machine system of AC Drive move back paper bowl motor configuration on large 2-3 times powers more confidential than the direct current (DC) of equivalent specifications just can satisfy the demands.The supporting transducer power that the increase of power of motor also causes simultaneously increases, so just the advantage of the application of alternating-current actuating system on rewinding machine by power increase offset.
