Abstract
The invention relates to an automatic material feeding control apparatus of a three-roller grinder, wherein an on/off power supply is sequentially connected with a relay and a photoelectric switch in series to form a loop, and a relay normally closed contact and a pneumatic electromagnetic valve are connected in series. According to the present invention, the photoelectric switch, the auxiliary relay, the pneumatic electromagnetic valve and other components are adopted to achieve the purpose of automatic control on pneumatic plunger pump work with the apparatus, such that the whole process of automatic material feeding of the three-roller grinder can be conveniently, safely, rapidly and accurately achieved, the difficult problem that material feeding requires the specialized personnel is overcome, the cost is saved, and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of automatic charging device, relate in particular to a kind of three-roll grinder automatic charging control device.
Background technology
Three-roll grinder is called for short three-roller, is applicable to the manufacture of the slurries such as paint, ink, pigment, plastics.Its operation principle is that three-roll grinder pushes mutually by the surface of three rollers of level and the friction of friction speed reaches grinding effect, and three-roll grinder is that high-viscosity material the most effectively grinds, dispersing apparatus.
Now, conventional three-roll grinder is mainly that the thickener that will grind by the air piston pump of air pressure control rises in the hopper of grinder, carry out continual grinding, the height of material level and the speed of material loading are by judging artificially and regulating, therefore, there is like this material loading inconvenience, coarse problem in the process need full-time staff of material loading operation and supervision.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and a kind of three-roll grinder automatic charging control device providing, thereby it can reach according to the accurate automatically material loading of the height of material level in hopper the object of automatic operation.
The object of the present invention is achieved like this:
A kind of three-roll grinder automatic charging control device, Switching Power Supply is connected with relay, optoelectronic switch successively and is formed loop, and relay normally-closed contact is connected with air-operated solenoid valve.
The L end of described Switching Power Supply is connected with the live wire that exchanges of 220V after connecting with breaker.
The model of described Switching Power Supply is DC12V.
Described relay is auxiliary reclay.
Described optoelectronic switch is NPN optoelectronic switch.
The present invention has obtained following technique effect:
The present invention is by utilizing the elements such as optoelectronic switch, auxiliary reclay, air-operated solenoid valve to reach the object of device Pneumatic automatic-control plunger displacement pump work, can be convenient, safety, realize fast and accurately the overall process of three-roll grinder automatic charging, overcome material loading and needed the difficult problem that special messenger is responsible, save cost, improved production efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is internal structure schematic diagram of the present invention;
Fig. 2 is circuit theory diagrams of the present invention.
Detailed description of the invention
A three-roll grinder automatic charging control device as shown in Figure 1-2, Switching Power Supply 1 is connected with relay 2, optoelectronic switch 3 successively and is formed loop, and relay normally-closed contact 4 is connected with air-operated solenoid valve 5.The L end of Switching Power Supply 1 is connected with the live wire that exchanges of 220V after connecting with breaker 6.The model of Switching Power Supply 1 is DC12V.Relay 2 is auxiliary reclay.Optoelectronic switch 3 is NPN optoelectronic switch.
While adopting said structure, start after three-roll grinder, breaker closes, normally-closed contact by auxiliary reclay is to air-operated solenoid valve power transmission, air-operated solenoid valve promotes air piston pump and by stock pipe 8 material loading of starting working, when the material level in hopper 7 rises to setting height, be responsible for the optoelectronic switch closure detecting, signal is passed auxiliary reclay back, its normally-closed contact disconnects, air-operated solenoid valve power-off, air piston pump stops toward material loading in hopper 7, after material level declines, the optoelectronic switch of being responsible for detecting disconnects, auxiliary reclay normally-closed contact resets, air-operated solenoid valve drives air piston pump to restart work.Periodic duty and so forth, realizes automatic charging control.
