Background
The rewinding machine is a special rewinding device for paper, mica tapes and films, and is used for rewinding paper rolls (called as original paper rolls) produced by a paper machine in sequence, and the paper is rewound to form finished paper and leaves the factory.
Because the paper roll wound by the paper winding machine is soft, the interior of the paper roll can be damaged or broken, the edges of two sides are irregular, the width of a paper web and the like can not be directly used for machines for paper processing or printing and the like, most paper types (such as newsprint, letterpress printing paper, packaging paper and the like) need to be subjected to processes of edge cutting, slitting, joint and the like by a rewinding machine, the paper roll core is rewound to form a certain specification, and the finished paper roll with certain tightness requirement can only leave a factory. The rewinding process is mainly to cut raw edges of base paper, then cut the whole base paper into a plurality of widths meeting the user specification, and simultaneously control the roll diameter of the finished paper roll to enable the finished paper roll to meet the outgoing specification.
When rewinding paper, the existing rewinding machine can vibrate by itself, the vibration can increase along with the increase of the winding speed of the rewinding machine, and once the vibration value is too large, the winding action is easy to misplace, so that the paper is broken, the normal operation of rewinding the paper is influenced, and the paper loss in the rewinding process is increased.

Detailed Description
The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.
As shown in fig. 1 and fig. 2, the speed regulation control system of the rewinding machine comprises:
the rewinding machine is provided with a paper feeding roller and a paper pressing roller in parallel, and one end of the paper feeding roller is connected with a motor;
the vibration detector is connected with the paper pressing roller and used for collecting the vibration value of the paper pressing roller and converting the vibration value into a signal to be conveyed outwards;
the PLC receives and judges the signals sent by the vibration detector and further sends out signals;
the frequency converter is connected with the motor, receives a signal sent by the PLC controller and controls the motor to change the working frequency;
the display screen is used for receiving and displaying signals sent by the PLC;
the vibration detector detects the vibration value of the paper pressing roller and then transmits a signal to the PLC controller, when the vibration value is higher than a set value, the PLC controller sends a signal to the display screen and the frequency converter, and the frequency converter controls the motor to reduce the working frequency and conduct troubleshooting and solution; and when the vibration value is lower than or equal to the set value, the PLC transmits a signal to the display screen.
When rewinding paper, the existing rewinding machine can vibrate by itself, the vibration can increase along with the increase of the winding speed of the rewinding machine, and once the vibration value is too large, the paper wound is easy to misplace, so that the paper is broken, the normal operation of rewinding the paper is influenced, and the paper loss in the rewinding process is increased.
Therefore, the utility model provides a rewinding machine speed governing control system sets up through the cooperation of vibration detector, PLC controller and converter, converts the vibration value of rewinding machine dancer roll (walk paper roll) into the signal and carry to the PLC controller and judge, and then passes through the motor of converter control rewinding machine by the PLC controller to the frequency of operation of control rewinding machine makes it accord with the operational requirement, guarantees the normal high-speed operation of rewinding machine, and is easy and simple to handle, can effectively reduce the risk of disconnected paper.
The working vibration of the rewinding machine is actually the vibration generated by driving the paper feeding roller by the motor, the paper pressing roller and the paper feeding roller rotate relatively and are in mutual extrusion contact, paper passes through the two rollers and is wound, therefore, the vibration frequency of the paper pressing roller is consistent with that of the paper feeding roller, and the vibration detection of the vibration value of the paper pressing roller by the vibration detector is actually the vibration detection of the paper feeding roller.
Specifically, a vibration detector is mounted on the platen roller, a vibration value of the platen roller is detected and then converted into a signal, the signal is transmitted to a PLC controller, an operator sets a set value in the PLC controller in advance according to the actual working condition, and the PLC controller judges according to the received signal and the set value.
When the vibration value is higher than the set value, the PLC sends a signal to the display screen and the frequency converter, the display screen displays the specific vibration value, and meanwhile, the frequency converter receives the signal and controls the motor to reduce the working frequency, namely the working frequency of the rewinding machine. At the moment, the operator checks the rewinding machine, determines the reason and solves the problem, and the normal work of the rewinding machine is recovered after the vibration value is reduced to the required range.
And when the vibration value is lower than the set value, the display screen receives the signal transmitted by the PLC and displays the specific vibration value until the vibration value reaches the set value.
Preferably, after the working frequency of the motor is reduced, if the vibration value is still higher than the set value, the PLC controller continues to send signals to the display screen and the frequency converter, and the frequency converter continues to control the motor to reduce the working frequency until the vibration value is lower than or equal to the set value; if the vibration value is lower than the set value, the frequency converter controls the motor to increase the working frequency until the vibration value is equal to the set value.
It should be noted that, after the motor reduces the working frequency and checks the reason, if the vibration value measured by the vibration detector is still higher than the set value, the PLC controller continues to control the frequency converter to reduce the working frequency of the motor, and continues to check the rewinding machine and solve the problem until the vibration value is lower than or equal to the set value.
If the vibration value is lower than the set value after the reason is checked, the frequency converter can control the motor to increase the working frequency, namely, the working speed of the rewinding machine is increased until the vibration value is equal to the set value.
When the vibration value is equal to the set value, the motor maintains the working frequency, namely the rewinding machine maintains the working speed, the rewinding work of the paper is normally carried out, the paper breaking risk of the paper is further reduced, and the using effect is good.
This rewinding machine speed governing control system reasonable in design, through the vibration detector, the cooperation setting of PLC controller and converter, convert the vibration value of rewinding machine dancer roll (walk the paper roll) into the signal and carry to the PLC controller and judge, and then pass through the motor of converter control rewinding machine by the PLC controller, thereby the operating frequency of control rewinding machine, make it accord with the operational requirement, guarantee the normal high-speed operation of rewinding machine, and is easy and simple to handle, can effectively reduce the risk of disconnected paper, therefore, the clothes hanger is strong in practicability, reduce the working loss of rewinding machine simultaneously, excellent in use effect.
