Description
Technical field
It the utility model is related to Extruder Control technical field, more particularly to a kind of aluminum section extruder fixed speed control system
System.
Background technology
In recent years, aluminium section bar with its traditional material such as attractive in appearance, light and handy, inexpensive, of fine quality it is incomparable the advantages of and building,
The industries such as decoration are widely used.Reliability and flexibility of the speed control relationship of extruder to equipment, Jin Erying
Ring the production efficiency and qualification rate to product.And traditional aluminum section extruder is controlled using relay circuit, its complex circuit,
Fault rate is high, poor reliability, and production efficiency is low.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of aluminum section extruder constant speed control
System processed, make complete machine operation more reliable reliable, significantly improve the extruding quality and production efficiency of aluminium section bar.
Technical scheme is used by the utility model solves its technical problem：
A kind of aluminum section extruder constant speed control system, including touch-screen, PLC, fixed speed control plate, speed-regulating potentiometer, ratio
Example pump electromagnet, displacement transducer, pressure sensor and extruder master cylinder, the touch-screen, PLC, fixed speed control plate phase successively
Even, fixed speed control plate is also connected with speed-regulating potentiometer, proportioning pump electromagnet, displacement transducer, pressure sensor respectively, proportioning pump
Electromagnet, displacement transducer, pressure sensor are connected with extruder master cylinder respectively.
Further, the power supply of the fixed speed control plate is DC24V, double pressure signal inputs.
Further, the fixed speed control plate can 1~4 proportion electro-magnet of external output.
Further, the fixed speed control plate is communicated using RX-232 modes and PLC.
Further, the fixed speed control plate uses the digital control plates of EPC-2800.
The utility model has the advantages that：Displacement transducer can be sent instead according to the extruder master cylinder speed of service
Feedback signal is to fixed speed control plate；Pressure sensor can detect that master cylinder operating pressure size；Proportioning pump electromagnet can change extruding
The size of owner's cylinder hydraulic fluid flow rate；Speed-regulating potentiometer can set the constant speed of service of extruder as needed.
Brief description of the drawings
Fig. 1 is Tthe utility model system schematic diagram.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated, a kind of aluminum section extruder constant speed control system, including touch-screen, PLC, fixed speed control plate, speed governing
Potentiometer, proportioning pump electromagnet, displacement transducer, pressure sensor and extruder master cylinder, the touch-screen, PLC, fixed speed control
Plate is sequentially connected, and fixed speed control plate also connects with speed-regulating potentiometer, proportioning pump electromagnet, displacement transducer, pressure sensor respectively
Connect, proportioning pump electromagnet, displacement transducer, pressure sensor are connected with extruder master cylinder respectively.
Fixed speed control plate is the core component of whole system control, and the fixed speed control plate can use EPC-2800 numeral controls
Making sheet.Its power supply is DC24V, double pressure signal inputs.Fixed speed control plate can 1~4 proportion electro-magnet of external output.Can also root
According to extruded object material feature, extruder master cylinder pressure size is detected by pressure sensor, so as to set master cylinder breakthrough pressure
The parameter adjusted with over pressure is adjusted, fixed speed control plate can also set master cylinder range, proportioning pump electromagnet minimax electricity
The parameter such as stream, master cylinder highest extrusion speed, pressure sensor ratio.
The fixed speed control plate can use RX-232 modes to be communicated with PLC.
Specifically, when extruder master cylinder is extruded with working condition, the speed-regulating potentiometer in operation touch-screen enters work
Speed inputs to fixed speed control plate, and fixed speed control plate output current gives proportioning pump electromagnet, oil pump is given extruder master cylinder fuel feeding,
Promote displacement transducer to send feedback signal again to fold feedback signal and work speed signal before to fixed speed control plate, PLC
Add, fixed speed control plate is input to after superposition and is compared computing, to determine speed deviation.If deviation rises, constant speed
Control panel output current declines, and proportioning pump electromagnet aperture diminishes, and extruder master cylinder hydraulic pressure oil stream amount diminishes immediately, master cylinder operation
Speed is reduced to the setting value of speed-regulating potentiometer.If deviation declines, fixed speed control plate output current rises, proportioning pump electricity
Magnet aperture becomes big, and extruder master cylinder hydraulic pressure oil stream amount becomes big immediately, and the master cylinder speed of service is improved to setting value, is thusly-formed and is closed
Ring control loop, realize that constant speed extrudes.
The utility model finds that extrusion speed is abnormal by detecting, and output feedback signal simultaneously carries out computing to signal, according to
Operation result adjust automatically extrusion speed, realize that constant speed extrudes.The systematic difference makes extruder operation become more stable reliable,
Significantly improve the extruding quality and production efficiency of aluminium section bar.
