Second, the calender roll group 1 and the calender roll group 2 can be configured with the same calender drive and control system.

Third, the extruder and the extruder 2 can also be equipped with the same extrusion drive and control system.

The working principle of the above embodiment 1 is roughly as follows:

The traveling mechanism drives the main body of the supporting extruder to move forward and backward (reciprocating back and forth) so that the extruder can enter and exit The calender is used to lock or release the machine head through the head lock, and it is also convenient to maintain the equipment. The extruder 2 can be used for the compounding extrusion of the rubber material A; the extruder can be used for the compounding extrusion of the rubber material B; the calendering roller group 2 of the calender is used for the calendering production of the rubber material A; the calender roll group 1 For the calendering production of the rubber B; the laminating device is used for the lamination production of the film A and the film B.

The calender roll set described above is provided with a calender drive and control system comprising: a vector inverter (driver). The working process and principle are as follows: The vector inverter (driver) is used to realize the closed-loop vector control of the pair of speeds of the calendering unit. The vector control can be used to make the driving motor of the calendering roller group one output the high-speed torque of the same speed at low speed. With conventional V/F control, the voltage drop of the motor increases as the speed decreases, resulting in insufficient excitation and the motor cannot obtain sufficient rotational force. In order to compensate for this deficiency, the inverter needs to increase the voltage to compensate for the voltage drop caused by the motor speed reduction. This function of the inverter is called torque boost.

The torque boost can increase the output voltage of the inverter, so that the output torque of the motor increases in proportion to the square of the voltage, thereby improving the output torque of the motor and improving the low output torque of the motor. Torque boost The function is to increase the output voltage of the inverter. However, even if a lot of output voltage is increased, the motor torque cannot be increased corresponding to the current. Because the motor current contains the torque component generated by the motor and other components (such as excitation, etc.).

The vector control can distribute the motor current value to determine the value of the generated motor current component and other components; the compensation can be optimized by responding to the voltage drop of the motor terminal, allowing the motor to generate a large amount without increasing the current. Torque. The speed regulation below the rated frequency is called constant torque speed regulation (T=Te, P<=Pe), and the speed regulation above the rated frequency is called constant power speed regulation (P=Te*Ie). The inner liner process requires no stretch of the rubber, and all use constant torque regulation.

The calender roll group 2 described above is provided with a calender drive and control system comprising: a vector inverter (driver). The working process and principle are as follows: The vector inverter (driver) is used to realize the closed-loop vector control of the two pairs of speeds of the calendering unit. The vector control can be used to make the driving motor of the calender unit 2 output the high-speed torque of the same speed at low speed. With conventional V/F control, the voltage drop of the motor increases as the speed decreases, resulting in insufficient excitation and the motor cannot obtain sufficient rotational force. In order to compensate for this deficiency, the inverter needs to increase the voltage to compensate for the voltage drop caused by the motor speed reduction. This function of the inverter is called torque boost.

The torque boost can increase the output voltage of the inverter, so that the output torque of the motor and the square of the voltage increase in proportion, thereby improving the output torque of the motor and improving the low output torque of the motor. The torque boost function is to increase the output voltage of the inverter. However, even if a lot of output voltage is increased, the motor torque cannot be increased corresponding to the current. Because the motor current contains the torque component generated by the motor and other components (such as excitation, etc.).

The extruder described above is provided with an extrusion drive and control system comprising: a vector inverter (driver). The working process and principle are as follows: The vector inverter (driver) is used to realize the closed-loop vector control of the pair of speeds of the extruder, and the vector control can be used to output the high-speed torque of the same speed at the low speed of the drive motor of the extruder. With conventional V/F control, the voltage drop of the motor increases as the speed decreases, resulting in If the excitation is insufficient, the motor will not get enough rotational force. In order to compensate for this deficiency, the inverter needs to increase the voltage to compensate for the voltage drop caused by the motor speed reduction. This function of the inverter is called torque boost.

The extruder 2 described above is provided with an extrusion drive and control system comprising: a vector inverter (driver). The working process and principle are as follows: The vector inverter (driver) is used to realize the closed-loop vector control of the two pairs of speeds of the extruder, and the vector control used can make the driving motor of the extruder 2 output the high-speed and the same torque at low speed. In the conventional V/F control, the voltage drop of the motor increases as the speed decreases, resulting in insufficient excitation and the motor cannot obtain sufficient rotational force. In order to compensate for this deficiency, the inverter needs to increase the voltage to compensate for the voltage drop caused by the motor speed reduction. This function of the inverter is called torque boost.

The above-mentioned machine head locking device can be realized in the following manner: First way, the machine of the extruder one The head of the extruder and the extruder 2 respectively have a locking mechanism; the second way, the first and second heads of the extruder are locked on the calender, and the two heads are used by the hydraulic locking mechanism on the frame of the calender Locked.

The above film A can be used as an inner liner film or as a transition film; when film A is used as an inner film, film B is used as a transition film; when film A is used as a transition film, film B is used as an inner film. .

The related technical content not mentioned in the above manner can be realized by referring to the prior art.
