Description

A kind of pair of rolling slitting mill electric-control system
Technical field
The utility model includes the non-ferrous metal applied technical field, is specifically related to a kind of pair of rolling slitting mill electric-control system.
Background technology
Slitting mill is a kind of specific purpose tool that nonferrous materials is processed into strip material.Existing slitting mill mainly is made up of three major parts, promptly rolling cut part, place unreeling part and placing the rolling part after the rolling cut part before the rolling cut part.
Main moment, the direct current generator of adopting of the rolling part of slitting mill originally carries out rolling; The defective that always exists and deficiency are that the rolling limit is irregular, degree of tightness differs or a series of problems such as product is too tightly wrinkling; Wrap-up is originally controlled through moment and is realized promoting, and its strength is enough but precision is not high.In the coiled plastic material production process, control accuracy can not guarantee, directly has influence on the quality of coiled material.In each link that metal material is handled, rolling is particularly important, because rolling is last process of handling metal material, the quality of the material apparent quality after the processing directly has influence on the height of its development quality and quality.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: the deficiency that is directed to prior art; A kind of pair of rolling slitting mill electric-control system is provided; This pair rolling slitting mill electric-control system utilizes the advanced person of PLC to control function, when guaranteeing the material rolling closely, neatly, not loose, quality of edges is good.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: a kind of pair of rolling slitting mill electric-control system is provided, it is characterized in that: comprise touch-screen, PLC module, frequency-variable controller, variable-frequency motor, near switch, unwinding device, rolling cut device and wrap-up; Said touch-screen adopts the I2C bus to be connected with the PLC module; Said PLC module is connected with frequency-variable controller; Said variable-frequency motor one end is connected with frequency-variable controller, and the other end is connected with wrap-up with unwinding device, rolling cut device; Saidly be connected with wrap-up near switch one end, the other end is connected with the PLC module.
Further, also comprise meter counter, meter counter one end is connected with wrap-up, and the other end is connected with the PLC module.
Further, said wrap-up comprises first rolling-up mechanism and second rolling-up mechanism.
Further, said rolling cut device comprises roller bearing cutter and following roller bearing cutter.
Further, said going up on roller bearing cutter and the following roller bearing cutter is respectively arranged with two pairs of hobboing cutters.
Further, said first rolling-up mechanism is connected with last roller bearing cutter; Said second rolling-up mechanism is connected with following roller bearing cutter.
In sum, two rolling slitting mill electric-control systems that the utility model provided have following advantage compared to prior art:
1, utilized the advanced person of PLC to control function, the monitoring on the wrap-up material volume footpath in real time near switch and change carrying out the motor speed adjustment of interpolation, when having guaranteed the material rolling thus closely, neatly, not loose, quality of edges is good.
2, because native system adopts touch screen human-computer interface, greatly enrich, made things convenient for control operation, both improved production efficiency and also reduced the cost of labor of producing.
Description of drawings
Fig. 1 is the theory structure sketch map of two rolling slitting mill electric-control systems.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done and to be described in detail:
As shown in the figure, this pair rolling slitting mill electric-control system comprises touch-screen, PLC module, frequency-variable controller, variable-frequency motor, near switch, unwinding device, rolling cut device and wrap-up; Said touch-screen adopts the I2C bus to be connected with the PLC module; Said PLC module is connected with frequency-variable controller; Said variable-frequency motor one end is connected with frequency-variable controller, and the other end is connected with wrap-up with unwinding device, rolling cut device; Saidly be connected with wrap-up near switch one end, the other end is connected with the PLC module; Also be provided with meter counter, meter counter one end is connected with wrap-up, and the other end is connected with the PLC module; Said wrap-up comprises first rolling-up mechanism and second rolling-up mechanism; Said rolling cut device comprises roller bearing cutter and following roller bearing cutter; Said going up on roller bearing cutter and the following roller bearing cutter is respectively arranged with two pairs of hobboing cutters; Said first rolling-up mechanism is connected with last roller bearing cutter; Said second rolling-up mechanism is connected with following roller bearing cutter.
The PLC module is the native system Central Control Module, and the operation of being responsible for receiving from touch-screen requires and send corresponding execution command.Be provided with converting unit in the PLC module, the data signal that PLC sends sends to frequency-variable controller through converting analog signal to, carries out Torque Control, promptly lets the torque of variable-frequency motor constant as far as possible, makes the wrap-up stable working, and variable-frequency motor control is rotated accurately.In addition, be used for monitoring the variation of the material coil diameter on two rolling-up mechanisms of wrap-up, and send to a corresponding diameter signal in the PLC module, send the adjustment signal by the PLC module again and give frequency-variable controller near switch.When material coil diameter was less on the wrap-up, variable-frequency motor rotated with fast speed.When the volume footpath became big, the PLC module was sent the instruction that slows down motor speed, and frequency-variable controller makes the variable-frequency motor rotating speed slack-off through reducing the out-put supply frequency, makes motor remain on stable rotating speed.
Calculate the output of material for ease and realize automatic cutter control; The utility model also is provided with meter counter; After configuring meter numerical value, when the outflow material reached this setting value, meter counter sent signal can for the PLC module; The PLC module can be suspended material rolling work and use the rolling cut device to carry out cutter to cut, also can be other operations that need.
Wrap-up is originally driven by moment and moves ahead, and is improved to now by the operation of frequency-variable controller drive variable frequency motor, realizes the automatic control of speed through machinery and electric integration.
In sum; The two rolling slitting mill electric-control systems that utilize the utility model to provide have utilized the advanced person of PLC to control function; Material volume footpath changes to carry out the motor speed adjustment on the wrap-up for monitoring in real time near switch of adding; When having guaranteed the material rolling closely, neatly, not loose, quality of edges is good; Also adopt touch screen human-computer interface, greatly enrich, made things convenient for control operation, both improved production efficiency and also reduced the cost of labor of producing.
Though describe in detail in conjunction with the specific embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
