Abstract
The invention relates to a control system for down feather classification processing, in particular to a wind speed control system of a down feather classifier based on a PLC (programmable logic controller), which is mainly applied to the down feather processing and manufacturing industry and belongs to the technical field of down feather processing. The control system comprises a main blower, the PLC, a step motor and a plurality of classifying boxes; according to feedback data from a wind speed sensor, the system adjusts the rotating speed of the blower and the position of a baffle plate automatically and precisely by controlling a rotating speed controller and the step motor by the PLC so as to change the wind speed in each classifying box and eliminate the individual difference of each classifier so that the wind speed in each classifying box is optimized.
Description
Technical field
The present invention relates to a kind of control system of eider down classification processing, relate in particular to a kind of wind speed control system for down-sorting machine, be mainly used in eider down processing and manufacturing industry, belong to the eider down processing technique field based on PLC.
Background technology
Roughly by adding hair, wash-out is dried in the preliminary working of eider down at present, ash disposal, and steps such as classification are formed, and wherein classification is that eider down is placed in the confined space, utilizes the principle of negative pressure air draught, eider down is divided into the production process of the product of different brackets by the difference of proportion.Classification is a ring of most critical in the preliminary working journey, and it has directly determined the quality of finished product eider down.Because the eider down classification is what to carry out according to the proportion difference of each composition in the raw material, so the wind speed in each utility box of classifier has very big influence for classification results, can regulate wind speed by the baffle position that changes in rotation speed of fan and each utility box in the actual production.The problem that conventional clean machine on the present domestic and international market generally faces is: 1. the down-sorting machine individual difference is bigger, so the wind speed in the utility box of correspondence can be variant in the different classifiers under the rotation speed of fan situation identical with baffle position.The tradition down-sorting machine can only rely on manual the adjusting to eliminate individual difference in actual production.But owing to be manual adjustment, thus not only consuming time but also inaccuracy, so regulating effect is not good.Normal when many classifiers occurring and classifying same raw material simultaneously in actual production, classification results has than big-difference, thereby causes repeatedly classifying, and has influenced the quality and the production efficiency of finished product eider down greatly.Since eiderdown raw material and class object often change, so need regulate the interior wind speed of each utility box respectively to reach the optimal classification effect.The tradition down-sorting machine be owing to can only rely on manual the adjusting, thus not only consuming time but also inaccuracy, so regulating effect is not good.In actual production, often do not cause repeatedly classifying, influenced the quality and the production efficiency of finished product eider down greatly because of classification reaches to fix one's aim in advance.
Both at home and abroad for rotation speed of fan and the utility box baffle position that can accurately regulate each down-sorting machine according to identical target wind speed value automation, report is not arranged as yet at present thereby eliminate the down-sorting machine individual difference and make the interior wind speed of each utility box reach optimum equipment.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of down-sorting machine wind control system based on PLC is provided.This system is according to the feedback data of air velocity transducer, come automation accurately to regulate rotation speed of fan and baffle position by PLC control rotational speed governor and stepper motor, thereby change wind speed in each utility box, eliminate each classifier individual difference and make the interior wind speed of each utility box reach optimum.
The present invention realizes with following technical scheme: a kind of wind speed control system for down-sorting machine, it comprises: main air blower, PLC programmable logic controller (PLC), stepper motor and several utility boxs is characterized in that: this control system has rotation speed of fan control device, utility box baffle position control device and air velocity transducer;
(1) rotation speed of fan control device: the blower fan main shaft motor connects rotational speed governor, and rotational speed governor receives the control of PLC input carrying out rotating speed;
(2) utility box baffle position control device: in each utility box of down-sorting machine baffle plate is arranged, be fixed with stepper motor on each baffle plate, rotate by stepper motor and drive baffle plate and move the controllable register position;
(3) air velocity transducer: place in air inlet place and each utility box, the wind speed that records in real time in air inlet and each utility box is fed back to PLC.
Described air velocity transducer places in air inlet place and each utility box, the wind speed that records in real time in air inlet and each utility box is fed back to PLC, according to the target wind speed value in each utility box, PLC compares feedback result and target wind speed value, if greater than, then by regulating utility box Internal baffle position and rotation speed of fan, make wind speed reduce, otherwise, wind speed is raise, consistent up to the actual wind speed value with the target wind speed value.
Advantage of the present invention is: according to different raw materials and class object, utilize PLC to come to come automation accurately to regulate baffle position in rotation speed of fan and each utility box according to target wind speed and actual wind speed, eliminate the individual difference of each classifier, improve finished product eider down quality and production efficiency.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a PLC control circuit schematic diagram;
