Abstract
The utility model relates to an extrusion machine, in particular to a control system for extruding screw of extrusion machine, comprising a control panel and a controller. A signal output terminal of the controller is connected with a motor driver, a current output terminal of the motor driver is connected with a motor, and a power output terminal of the motor is connected with an extruding screw which is connected with a feedback signal receiving terminal of the controller through a rotation speed feedback circuit. The controller outputs signals of rotation, stopping, acceleration, deceleration and the like of the extruding screw, and transmits the signals to the motor driver which drives the motor to rotate according to the signals output by the controller. Rotation speed signals of the motor are transmitted to the controller through the feedback circuit, and the controller obtained adjusted value for rotation speed of the motor through calculation and transmits the signals to the motor driver after the controller receives the feedback signals, thereby playing a function of immediately regulating the rotation speed of the extruding screw and ensuring accuracy of rotation speed.
Description
Technical field
The utility model relates to a kind of extruder, especially relates to a kind of control system of extruder extrusion screw rod.
Background technology
Extruder is the requisite plant equipment that a kind of plastics, rubber-moulding are made the field, extruder is under screw acting molten plastic to be extruded by the extrusion of solid shape, it cuts behind water-cooled shaping under the hauling machine effect. and a large amount of the continuing that is mainly used in various same cross-sectional products produces, as manage rod profile shapes etc., also can be used for the modifying plastics granulation.Yet existing extruder still exists the rotating speed of extrusion screw rod and controls coarse problem, and this quality to product can be brought very big influence, causes the percent defective height.Also there is the people that some improved trials have been done in the control that extruder has squeezed screw rod.As the patent No. is that the utility model of CN200520125152.0 discloses a kind of numerical control extruder and comprises screw extruder and industry control microcomputer, it is characterized in that: magnetic resistance switch speed-adjustable motor is set, magnetic resistance switch speed-adjustable motor is by transmission mechanism connecting screw rod extruder, electric machine controller connects magnetic resistance switch speed-adjustable motor and industry control microcomputer, data acquisition card connection industry control microcomputer.Magnetic resistance switch speed-adjustable motor provides numerical-control screw rod extruder power, and the rotating speed of the instant gauge tap magneto resistance speed-regulating motor of electric machine controller is with the change in rotational speed of control screw extruder screw rod.This control method can't in time obtain the actual speed data of extrusion screw rod owing to there is not the feedback information of extrusion screw rod rotating speed, so the rotating speed that also can't adjust screw rod in time, automatically is to adapt to the processing needs.
Summary of the invention
The utility model mainly is to solve existing in prior technology extruder extrusion screw rod rotating speed can't in time feed back, thereby cause can't adjust in time, automatically rotating speed etc. technical problem, provide a kind of convenient to operation, can in time look the extruder screw control system that the extrusion screw rod change in rotational speed is regulated.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of control system of extruder extrusion screw rod, comprise control panel, controller, the signal output part that it is characterized in that described controller links to each other with a motor driver, the current output terminal of motor driver links to each other with motor, the clutch end of motor links to each other with extrusion screw rod, and extrusion screw rod links to each other with the feedback signal receiving terminal of controller by the feedback circuit of rotating speed.Controller be responsible for sending screw rod rotation, stop, the signal of acceleration, deceleration etc., and signal passed to motor driver, motor driver rotates according to the signal drive motor of controller.Motor speed signal is issued controller by feedback circuit again, behind the controller receiving feedback signals, by calculating the adjusted value of motor speed, and signal is issued motor driver, play the effect that the rotating speed of extrusion screw rod is adjusted immediately, make rotating speed more accurate.
As preferably, the feedback circuit of described rotating speed is provided with an encoder, and encoder and extrusion screw rod are suitable, and the signal output part of encoder links to each other with the feedback signal receiving terminal of described controller.The coding apparatus can read rotating speed of motor immediately, and the rotating speed of motor signal is issued controller.
As preferably, described encoder is an incremental encoder.Incremental encoder is to make zero as numerical digit in any position, and then starts at accumulative total displacement or numerical digit amount that angle increased or reduced with this point.And these needs in the function of extrusion screw rod, have just in time been satisfied.
As preferably, described encoder photoelectricity incremental encoder.
As preferably, described control panel comprises numeral input/program editing button, start button, manual switching button, pause button, and above button links to each other with controller respectively.Numeral input/program editing button can be set rotating speed for screw rod, and rotation time is manual or automatic etc.
The beneficial effect that brings of the present utility model is, the rotating speed that this control system can prepare control extruder extrusion screw rod, and can reach timely and regulate automatically.
Therefore, the utlity model has characteristics such as rational in infrastructure, easy to operate.
Description of drawings
Accompanying drawing 1 is a kind of fundamental diagram of the present utility model;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of fundamental diagram of the present utility model, a kind of control system of extruder extrusion screw rod, comprise control panel, controller, the signal output part of controller links to each other with a motor driver, the current output terminal of motor driver links to each other with motor, the clutch end of motor links to each other with extrusion screw rod, and extrusion screw rod and a photoelectricity incremental encoder are suitable, and the signal output part of this encoder links to each other with a signal receiving end of controller.Control panel comprises numeral input/program editing button, start button, manual switching button, pause button, and above button links to each other with controller respectively.
In process manual or control automatically, the operator sends run signal by control panel to system, control panel is according to the signal control motor driver that obtains, motor driver is controlled rotating speed of motor by the electric current of control input motor, the driven by motor extrusion screw rod rotates, the tach signal of extrusion screw rod is given controller by encoder feedback again, by calculating the velocity deviation of extrusion screw rod, and rotating speed of motor is regulated after the controller received signal by the control motor driver.
So the utility model has been realized the instant control of extruder extrusion screw rod, feedback and has been regulated.
