Problems solved by technology

When the user requests to control the drive with the field bus, there is a substantial problem, because the communication protocol card is used for the field bus communication, and the drive that can only add one card cannot be added with a take-up card. If it is used, it can be added. Drivers for two cards add another cost

Embodiment 1

[0024] Constant tension center coiling control system, such as figure 1 , 2 As shown, a controller is installed between the motor and the take-up roller, such as image 3 As shown, set the minimum winding diameter value in the CPU of the controller (PLC), start the motor, the motor speed is equipped with PG detection to collect the speed detection signal in real time, and transmit the speed signal to the DC speed control device, through the DC speed control device Feedback to the controller CPU, the real-time production line speed of the coiling roller is transmitted to the CPU through detection, the controller receives the production line speed, and the software system calculates according to the following formula and outputs the coil diameter value to the DC speed control device to adjust the coiling center.

[0025] Principle formula of the present invention:

[0026] (1) Maximum load torque [NM]: M 0 = M 1 +M 固

[0027] (2) Maximum control torque [NM]: M 1 =F S(max...

Abstract

The invention relates to a rubber rolling apparatus, in particular to a constant-tension central rolling control system relating to a central rolling roller and a motor. A controller is arranged between the motor and the rolling roller; a lowest rolling diameter is set in the controller, then the motor is started and the speed of the motor is fed back to the controller through a DC speed regulator and the controller simultaneously receives the product-line speed of the rolling roller, and after the calculation of a software, the rolling diameter value is output to the DC speed regulator. The invention is mainly applied to the constant-tension central rolling of rubber industry and also can be widely applied to the constant-tension central rolling of other industries. The maneuverability and expressivity are higher and the maintenance is convenient; the running is stable and reliable; and the invention is most characterized in that the depending on the control card of the constant-tension central rolling is broken through and the control arithmetic is unique so as to lead the control system to get higher control precision and reduce the manufacturing cost.

Description

1. Technical field: [0001] The invention relates to a kind of rubber calendering equipment, in particular to relatively large tension calendering production. 2. Background technology: [0002] In the rubber industry, the coiling control used in the rubber calendering production line was the earliest manual tension control, which was not constant and not timely. Later, it was developed into an analog control panel to control the tension, and its stability has not yet been resolved. At present, DC motors are mainly used as drives, which are driven by DC drivers produced by different manufacturers. In this case, it is necessary to apply a coiling card matched with the driver. The coiling card controls the coiling tension by controlling the output current of the driver. , the principle is to use the stalling of the DC motor. When the user requests to control the drive with the field bus, there is a substantial problem, because the communication protocol card is used for the fie...
