A kind of drier ejecting plate acceleration-controlled system, comprise and add speed motor and contactless switch, electric motor starting is accelerated in described contactless switch control, described acceleration motor directly and ejecting plate equipment connection, also comprise PLC controller and frequency converter, described PLC controller is connected with frequency converter and contactless switch simultaneously, and the described frequency converter while is connected with contactless switch, described PLC controller control contactor switch on and off and control simultaneously the rangeability of frequency converter frequency.
Further, also comprise circuit breaker and the speed motor that adds for subsequent use, described circuit breaker is connected with the contactless switch and the contactless switch that adds speed motor for subsequent use that add speed motor.
Further, described in go out on board device to be also provided with photoelectric switch, the position signal of the sheet material that is dried is transferred to PLC controller by described photoelectric switch, when sheet material arrives when desired location, PLC controller is to contactless switch and frequency converter actuation signal.
Further, described frequency converter is current inverter or voltage transducer.
Compared to the prior art the utility model, has following beneficial effect:
By frequency converter is set, the speed motor that adds with power frequency startup is converted into variable frequency starting, reduce the impact of existing power frequency startup to chain and running roller, the service life of having improved chain and running roller, the equipment loss of reduction.
By PLC controller is set, realize the accurate control to accelerating motor starting time, and the accurate control that frequency converter frequency is changed, realize the production control becoming more meticulous, guarantee conforming product rate.
By circuit breaker and motor for subsequent use are set, guarantee the continuation of production process, not because of motor et out of order breaks in production.
By photoelectric switch is set, realize the precision control to be dried sheet material walking position and ejecting plate order, the sheet material order ejecting plate of guaranteeing to be dried, improves yield rate.
The required element of this control system is few, controls path direct, maintenance and easy to connect.

Fig. 1 is the utility model control principle drawing.
Reference numeral: 1-PLC controller, 2-frequency converter, 3-contactless switch, 4-add speed motor, 5-goes out board device, 6-photoelectric switch.
Detailed description of the invention
For making goal of the invention of the present utility model, technical scheme and beneficial effect more cheer and bright, below in conjunction with accompanying drawing, embodiment of the present utility model is described, it should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.
Fig. 1 is the utility model control principle drawing.As shown in Figure 1, a kind of drier ejecting plate acceleration-controlled system, comprise and add speed motor 4, contactless switch 3, PLC controller 1 and frequency converter 2, described PLC controller 1 is connected with frequency converter 2 and contactless switch 3 simultaneously, described frequency converter 2 is connected with contactless switch 3 simultaneously, described PLC controller 1 control contactor 3 switch on and off and control simultaneously the rangeability of frequency converter 2 frequencies.Contactless switch 3 is controlled and is added speed motor 4 and start, described in add speed motor 4 and be directly connected with the chain that goes out board device 5.The quantity of described contactless switch 3 and add speed motor 4 quantity and go out board device 5 ejecting plate chain quantity all equate, in the present embodiment, be given the dehumidification system of plasterboard, its ejecting plate system is generally 10 or 12, and the quantity of described frequency converter 2 interfaces is no less than the quantity of contactless switch 3.
Referring to Fig. 1, in order to realize the precision control to be dried sheet material walking position and ejecting plate order, the sheet material of guaranteeing to be dried is ejecting plate sequentially, eachly go out to be also provided with at least one photoelectric switch 6 on board device 5, the position signal of the sheet material that is dried is transferred to PLC controller 1 by photoelectric switch 6, and in the time that sheet material arrives desired location, PLC controller 1 is given frequency converter and corresponding Contactor Starting signal, signal is transferred to the corresponding speed motor that adds by corresponding contactless switch, accelerates driven by motor and go out board device ejecting plate.In general gypsum board production line, in schematic diagram, the value of n is 10～12 layers, is the situation of 10 layers in the present embodiment.
The working process of the present embodiment is: PLC controller 1 obtains the signal providing in ejecting plate system, in the time reaching slat element, PLC controller 1 sends Continuity signal to the corresponding contactless switch of board device that goes out that reaches slat element, simultaneously, starting frequency converter accelerates to adding speed motor to high frequency slowly from the low frequency of setting, thereby realize motor gradual change to high speed by low speed, alleviated impulsive force.
For the continuity that ensures to produce, in other embodiments, this control system also can comprise circuit breaker and the speed motor that adds for subsequent use, described circuit breaker is connected with the contactless switch and the contactless switch that adds speed motor for subsequent use that add speed motor, in the time that a certain road adds speed motor and breaks down, can start the speed motor that adds for subsequent use by circuit breaker, not stop production thereby realize.
The utility model, except the ejecting plate control of producing for sheet material, also can be used for the control of the lower linear velocity of the complete lower manufacturing line of packaging product packaging etc.
Although the embodiment that the utility model discloses as above, the embodiment that its content just adopts for the ease of understanding the technical solution of the utility model, is not intended to limit the utility model.Technical personnel under any the utility model in technical field; do not departing under the prerequisite of the core technology scheme that the utility model discloses; can in the form of implementing and details, make any amendment and variation; but the protection domain that the utility model limits, the scope that still must limit with appending claims is as the criterion.
