A kind of automatic weighting feed proportioning system
Technical field
This utility model relates to technical field of automation, particularly a kind of automatic weighting feed proportioning system.
Background technology
nullIn chemical industry or food industry produce,Process the product of finished product,Generally require multiple raw material and carry out hybrid process,By changing the consumption of processing raw material mixing,Or change the sequencing of raw material mixing,Or the factor such as mixing velocity and time,Different quality can be produced、Color、The discrepant product such as abnormal smells from the patient,And the consumption of raw-material mixing,Order before and after mixing,The time of mixing and the speed of mixing,Use and manually mix,Often workload is huge,Combined amount、Incorporation time、Order by merging technique etc. easily goes wrong,Some mixed raw material abnormal smells from the patient simultaneously,Easily damage health,Can not directly contact,Therefore a set of structural safety of continual exploitation,Reliability is high,The raw-material mixing consumption of different mixing、Mixing velocity and order by merging easy to control raw material configuration system,Meet industrial production demand.
Summary of the invention
In order to overcome the disadvantages mentioned above of prior art, the purpose of this utility model is to provide a kind of that be capable of automatic blending, the mixing consumption of dispensing, mixing velocity, and order by merging is controlled and easy to adjust, safe and reliable automatic weighting feed proportioning system.
This utility model solves its technical problem and be the technical scheme is that
A kind of automatic weighting feed proportioning system, wherein: include several head tanks, automatically controlled charge pump with head tank outlet, material-compound tank, converter, PLC, weighing instrument, touch screen control system, described automatically controlled charge pump is connected with material-compound tank by feeding tube, the discharging opening of described automatically controlled charge pump is additionally provided with charging electrically-controlled valve, the outlet of described material-compound tank is provided with dispensing electrically-controlled valve, the lateral wall of described material-compound tank is provided with weight sensor, described weighing instrument is connected with weight sensor by holding wire, described converter is connected with automatically controlled charge pump by holding wire, the data output end of described PLC is connected to weighing instrument, converter and charging electrically-controlled valve, input is connected to touch screen control system, communication ends is connected to PC.
As further improvement of the utility model: described touch screen control system includes data disaply moudle, head tank selects control module, data up-down adjustment module, and charging rate adjustment module.
Compared with prior art, the beneficial effects of the utility model are: this utility model uses PLC to control, good reliability, mixing mixing velocity and the order by merging of raw material is controlled by automatically controlled charge pump and charging electrically-controlled valve, the mixing consumption of raw material is controlled by weighing instrument, the mixing consumption of each raw material in production technology can be regulated by touch screen control system, mixing velocity, control program by PC adjustable PLC Product Process, this utility model uses automatic proportioning weighing system, avoid human error to make mistakes the product quality accident caused, reduce personal security accident risk, and the mixing consumption of each raw material in production technology, mixing velocity, incorporation time is easy to adjust, can be widely applied to coating, auxiliary agent, cosmetics, in the dispensing hybrid process system of the technique applications such as articles for washing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Illustrate with embodiment, this utility model to be further illustrated in conjunction with accompanying drawing:
nullA kind of automatic weighting feed proportioning system,Wherein: include several head tanks 1,Automatically controlled charge pump 2 with head tank outlet,Material-compound tank 3、Converter 4、PLC 5、Weighing instrument 6、Touch screen control system 7,Described automatically controlled charge pump 2 is connected with material-compound tank 3 by feeding tube 8,The discharging opening of described automatically controlled charge pump 2 is additionally provided with charging electrically-controlled valve 9,The outlet of described material-compound tank 3 is provided with dispensing electrically-controlled valve 10,The lateral wall of described material-compound tank 3 is provided with weight sensor 11,Described weighing instrument 6 is connected with weight sensor 11 by holding wire,Described converter 5 is connected with automatically controlled charge pump 2 by holding wire,The data output end of described PLC 5 is connected to weighing instrument 6、Converter 4 and charging electrically-controlled valve 9,Input is connected to touch screen control system 7,Communication ends is connected to PC 12.
Described touch screen control system includes data disaply moudle, head tank selects control module, data up-down adjustment module, and charging rate adjustment module, select control module can select to need the head tank adjusted to number by head tank, can be adjusted mixing consumption and the mixing velocity etc. of corresponding raw material by data up-down adjustment module and charging rate adjustment module, easy to adjust fast.
When system dispensing, PLC sends charging control instruction, PLC selects corresponding head tank to number by controlling converter, open the charging electrically-controlled valve of corresponding head tank numbering and automatically controlled charge pump, raw material enters material-compound tank, now dispensing electrically-controlled valve is closed, when weighing instrument detects that raw material reaches preset value, PLC, control charging electrically-controlled valve close and stop automatically controlled charge pump, now open dispensing electrically-controlled valve, more than complete primary material counterweight, the mixing consumption of corresponding head tank can be changed by touch screen control system, mixing velocity, production and processing technology can be adjusted by PC, feed change order by merging, the parameters such as mixing consumption.
In sum, after those of ordinary skill in the art reads this utility model file, conceive according to the technical solution of the utility model and technology and make other various corresponding conversion scheme without creative mental work, belong to the scope that this utility model is protected.
