When the two deviate is excessive, by audible-visual annunciator, report to the police immediately, when the coating weight of calculating gained is greater than reference value, PLC controller is controlled automatically to the speed of servo-driver, the rotating speed that is about to applicator roll tunes up to reduce coating weight, otherwise slow down, guarantee thus coating weight accuracy, realize the automation of coating weight and control.
Generally speaking coating width is less than base material width, it is that the width between two gear blob of viscoses decides in multiple roll glue coating groove, it can be by direct input system after manual measurement, also can be installed on a baffle plate wherein by a ultrasonic distance-measuring sensor, be used for measuring two distances between baffle plate, complete automatic detection.Concrete, described coating width testing agency comprises ultrasonic distance-measuring sensor and meter counter, and described ultrasonic distance-measuring sensor is arranged on wherein on a gear blob of viscose.Rising edge meter counter while joining glue starts counting, stops when joining glue rising edge counting next time.
Described liquid level sensor is ultrasonic liquid level sensor, this liquid level sensor be arranged on glue groove in massey coater structure directly over.With ultrasonic liquid level sensor, detect the liquid level of glue groove, when the liquid level while simultaneously judging that by PLC joined glue last time and this are joined glue, obtain liquid level, by twice liquid level difference, calculate single and join glue weight, also to glue preparation machine, provide and join glue instruction simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the online regulator control system of a kind of coating weight of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The online regulator control system of a kind of coating weight, as shown in Figure 1, comprise massey coater structure 1, described massey coater structure 1 is connected with servomotor 2, for glue, have glue preparation machine 5 to massey coater structure 1, described servomotor 2 connects by servo-driver 3 PLC controller 4, described PLC controller 4 communication link are connected to man-machine interface 10, this PLC controller 4 and glue preparation machine 5 control connections, described PLC controller 4 control connection acousto-optic alarms 6, be provided with liquid level sensor 7 corresponding to described massey coater structure 1, coating width testing agency 8 and coating length detection mechanism 9, described liquid level sensor 7, coating width testing agency 8 is connected with PLC controller 4 with coating length detection mechanism 9.
In the glue coating groove of massey coater structure 1, be marked with coating fluid, the transmission by between each roller, is coated to coating fluid on base material.The rotating speed of applicator roll determines coating thickness, and its rotating speed is decided by servomotor 2, and servomotor 2 is subject to 4 regulation and control of PLC controller by servo-driver 3.The Thickness Ratio of directly measuring coating is more difficult, thereby the liquid level of measuring coating fluid in glue coating groove by liquid level sensor 7 is to obtain glue consumption, coating width testing agency 8 and coating length detection mechanism 9 can measure the area of coating, by PLC controller 4, carry out computing, glue consumption can obtain the coating weight in certain hour divided by spreading area, and coating weight and the reference value of calculating gained are compared.
