| Electrical control characteristics |
----The control system is based on PLC, and PLC sends out control
instructions. PLC completes the single action or linkage control
requirements of the production line, and realizes the monitoring of
the operation status and operation parameters of the production
line ----The software package of control system has the function of
uploading and downloading all kinds of cable production process
formula, and can download the corresponding control formula
parameters according to the cable parameters to be processed ----The control system has the function of recording and printing
the operation status and alarm status of production line equipment ----The constant tension control mode is adopted for front and rear
traction to ensure the constant Online Tension of double traction.
The tension can be set and modified manually |
4.10 Electronic control system
4.10.1 Power supply: three phase five wire system, 380V (± 10%),
50Hz, single-phase control voltage of 220V
4.10.2 The operating system of the whole machine is controlled by
Siemens PLC module, which can be controlled by single action or
linkage. And through Siemens 10.1 inch touch screen visual
operation.
4.10.3 The communication control between PLC and frequency
converter is adopted, which has higher precision and faster
response than analog speed control. Meanwhile, PLC is equipped with
Ethernet interface, so users can monitor remotely.
4.10.4 The whole machine is a dual control system: analog speed
regulation and manual self reset knob speed regulation are set on
the touch screen,
and the parameters can be set and adjusted freely through the touch
screen
or self reset knob speed regulation.
4.10.5 The main machine and traction motor of the extruder are
domestic
high-quality brand DC motor, controlled by Parker 590 DC speed
regulation system,
and the latest generation of intelligent electronic display
calculus temperature controller
is selected as the temperature control instrument, with the
temperature control accuracy of ± 2 ℃.
4.10.6 The panel is equipped with all kinds of instruments,
indicators, switches and other necessary components, and all kinds
of overload, overheating, overcurrent protection functions are
complete,
4.10.7 The low-voltage components of the whole machine are all of
the top brands in China (Chint or Schneider), with the advantages
of stable starting, running and stopping of the production line,
energy saving and consumption reduction.
4.10.8 The control box is made of high-quality anodized aluminum
profiles and aluminum die-casting corner parts, with simple and
stable appearance and easy operation. The main control box is
equipped with dust-proof filter device to prevent dust from
affecting the service life of electrical components in the cabinet.
The safety protection of the production line meets the requirements
of national regulations
