The precision glue spreading control system for the glue spreader solves a problem of tension between a traction motor and the rubber roller, a problem of speed difference between the spreading roller and the rubber roller and a problem of roller distance between the metering rollers and the spreading roller, detects the quality of products in real time through the thickness measuring system, and sends a signal to regulate the glue spreading speed when the quality exceeds the set allowable range so as to ensure the quality of the products.
Description
Technical field
The present invention relates to the accurate gluing control system of a kind of glue spreader.
Background technology
Glue production line is the key equipment of carbon fiber prepreg factory, glue production line is implemented in the single face uniform gluing of release liners, its precision is weighed the goods precision by the weight of sizing material in every square metre, from being used for of carbon fiber, carbon fiber is a kind of new material of mechanical property excellence, its proportion is less than 1/4 of steel, carbon fiber resin composite material tensile strength is generally all more than 3500Mpa, be steel 7-9 doubly, tensile modulus of elasticity is that 23000-43000Mpa also is higher than steel, and carbon fiber is dual-use new material, belong to technology-intensive type and the responsive critical material of politics, from these characteristics of carbon fiber, this equipment of producing carbon fiber also is very commercioganic, because the Special geography status of carbon fibre material, developed country blocks the technology and the raw material of the production equipment of this material all the time to China.
Summary of the invention
The purpose of this invention is to provide a kind of accurate gluing control system of glue spreader that can accurately control the glue spreader quality of item.
The technical scheme that the present invention is adopted for achieving the above object is: the accurate gluing control system of a kind of glue spreader, this system comprises the PLC control system, thickness measuring system and executing agency, described PLC control system is connected by the DP bus with executing agency, described thickness measuring system is connected with executing agency with the PLC control system with analog quantity by switching value, described executing agency comprises metering one roller, measure two rollers, glue spreader, rubber rollers, chill roll and carry-over pinch rolls, described glue spreader is installed in metering one roller and measures between two rollers, rubber rollers is installed in the glue spreader lower end, and chill roll and carry-over pinch rolls are installed in the both sides of rubber rollers respectively.
Described PLC control system comprises roll adjustment control, logic control system and driving control system.
Described driving control system comprises carry-over pinch rolls drive motors, metering one roll drive motor, metering two roll drive motors, glue spreader drive motors, rubber rollers drive motors and chill roll drive motors.
Be provided with tension pick-up between described glue spreader and the carry-over pinch rolls.
The accurate gluing control system of glue spreader of the present invention, by solving the speed difference problem between strain problem, glue spreader and the rubber rollers between traction electric machine and the rubber rollers, the roll spacing problem of metering roll and glue spreader, determined the gluing quality of release liners, determined release liners before entering glue spreader, will guarantee the flatness of paper, determined every square metre quality of release liners, by thickness measuring system detection Products Quality at every moment, when surpassing the allowed band of setting, adjust the speed of gluing to signal, thereby guarantee Products Quality.

The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the accurate gluing control system of a glue spreader of the present invention control flow chart.
Fig. 2 is the accurate gluing control system of a glue spreader of the present invention PLC control system circuit diagram.
Fig. 3 is the accurate gluing control system of a glue spreader of the present invention executing agency structural representation.
Among the figure: 1, metering one roller; 2, glue spreader; 3, metering two rollers; 4, rubber rollers; 5, chill roll; 6, carry-over pinch rolls.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the accurate gluing control system of glue spreader of the present invention, comprise the PLC control system, thickness measuring system and executing agency, the PLC control system is connected by the DP bus with executing agency, thickness measuring system is connected with executing agency with the PLC control system with analog quantity by switching value, executing agency comprises metering one roller 1, measure two rollers 3, glue spreader 2, rubber rollers 4, chill roll 5 and carry-over pinch rolls 6, glue spreader 2 is installed in metering one roller 1 and measures between two rollers 3, rubber rollers 4 is installed in glue spreader 2 lower ends, chill roll 5 and carry-over pinch rolls 6 are installed in the both sides of rubber rollers 4 respectively, the PLC control system comprises roll adjustment control, logic control system and driving control system, driving control system comprises the carry-over pinch rolls drive motors, measure a roll drive motor, measure two roll drive motors, the glue spreader drive motors, rubber rollers drive motors and chill roll drive motors, be provided with tension pick-up between glue spreader and the carry-over pinch rolls, the course of work of the accurate gluing control system of glue spreader is: first-selection, by the given thickness measuring benchmark of PLC control system, signal is transported in the thickness measuring system, then, thickness measuring system detects the actual (real) thickness of goods, again should detected actual (real) thickness signal feedback in the PLC control system, calculate the thickness difference of goods by the PLC control system, by the PLC control system this thickness difference signal is flowed to executing agency again, adjust by executing agency.
This system at first wants the depth of parallelism between gluing roller that machinery guarantees and traction roller and the parallel of horizontal plane and two rollers, between glue spreader and carry-over pinch rolls, there is high-precision tension pick-up to detect the tension force of paper, the actual tension of Dpv paper, in the upper system of PLC control system, provide the tension force of the paper of technological requirement, the setting tension force of DSV paper, these two values (Dpv and Dsv) are as a kind of algorithm in the PID(logic control system) setting value and actual value in the control algolithm, requirement obtains an output valve Dcv behind the pid algorithm obtains traction electric machine then by formula once speed set-point, Dspeed_set=Dmain_speed (1+X*Dcv/Y), X is the percentage of main frame speed, and Y is the maximum of PID output; In whole system complementary seeing of can not isolating, mainly be that coating in release liners is liquid material, because loaded material between metering roll and the glue spreader, so require the roll spacing precision between metering roll and the glue spreader very high, manufacturing technique requirent reaches 0.001mm, except machinery exigent precision in processing, electric mainly be the precision of the rotation of requirement control roll adjustment motor, so know that in this system we adopt servo-control system, make the running accuracy of motor reach branch and precision, more can influence the quality of release liners under comparing, because glue spreader speed difference the quality of material on release liners different with rubber rollers is different, and when moving in system because the influence of the temperature of environment and other some unknown factors all can have influence on quality of material on the release liners, in this case we just need a closed-loop system come at every moment the glue spreader of adjusting and the speed difference between the rubber rollers, guarantee to produce high-precision goods, thickness measuring system detection Products Quality at every moment by NDC, when surpassing the allowed band of setting, adjust the speed of gluing to signal, thereby guarantee Products Quality.
