Description
Technical field:
The utility model is relevant with scale material precision control device.
Background technology:
For a long time, leaning on the material deadweight that material is carried out in the device of weight batching, people attempted several different methods to its proportioning accuracy control, but the solution that never finds.General way is at present: 1, with two batching doors, do thick batching door for one, and do smart batching door for one; 2, adopt the way of interrupted feed to carry out accurate dosing.
Adopt above two kinds of ways to prepare burden, can meet the demands within the specific limits, but certain defective is arranged, the master is:
1, when adopting smart batching door to prepare burden since essence join door should be little more a lot of than slightly joining door, this can bring bigger trouble or increase manufacturing cost frame for movement, if equally big, its batching effect is not again fine.
2, adopt interrupted batching can reduce the service life of electric elements.
The content of utility model:
The purpose of this utility model provides the controllable proportioning materials device of aperture, and its frame for movement is simple, takes up an area of to lack, and cost is low, long service life, and the proportioning accuracy height, operation and maintenance is convenient, and is applied widely.
The utility model is achieved in that
The controllable proportioning materials device of the utility model aperture, comprise silo 1, batching door 9 below the silo 1, batching door 9 is connected with the piston rod 11 of cylinder 2, it is characterized in that cylinder 2 has travel switch or magnetic switch 3 to be connected with the input of controller 6, the batching door has batching electronic scale 9 times, batching electronic scale is made up of weigh hopper 10 and sensor 12, the output of sensor 12 is connected with the input of controller 6, controller 6 two output respectively with magnetic valve 4,5 control end connects, magnetic valve 4, magnetic valve 5 is two five-way valves, compressed air connects the P mouth of magnetic valve 4 and the B mouth of magnetic valve 5, the A of magnetic valve 4, the B mouth is communicated with two gas ports of cylinder 2 respectively, the R mouth connects atmosphere, and the S mouth links to each other with the P mouth of magnetic valve 5, and the A mouth of magnetic valve 5 connects atmosphere.
Controller 6 is computer or single-chip microcomputer or Programmable Logic Controller, and the output of sensor 12 is through amplifier 13, and A/D converter 14 is connected with the input of controller 6.
The utility model does not increase installing space, increases manufacturing cost hardly.Can greatly improve the proportioning accuracy of material, and original mechanical mechanism does not need to do any change.This device goes for sand, the stone batching in concrete mixing plant (building), all electromechanical equipments that the proportioning materials of packaging facilities and other need lean on the deadweight of material to prepare burden.Simple in structure, long service life, operation and maintenance is convenient.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
The specific embodiment mode:
One stroke switch or magnetic switch 3 are installed on the cylinder 2 that proportioning materials door 9 is carried out switch motion, the determining positions of this switch can be adjusted arbitrarily, on the magnetic valve 4 of control batching door switch actuating cylinder a controllable electromagnetic valve 5, two magnetic valves being installed again is two five-way valves.
Comprise the cylinder 2 that is connected with batch hopper 1, be installed in the switch 3 on the cylinder, the magnetic valve 4 that is connected with cylinder 2, the magnetic valve 5 that is connected with magnetic valve 4, switch 3 links to each other with the input of Programmable Logic Controller 6, and the output of Programmable Logic Controller 6 is connected with magnetic valve 4, magnetic valve 5.The aperture of batching door is determined by the position of the switch that is installed on the cylinder 2.Proportioning materials door 9 is arranged below the silo 1, weigh hopper 10 is arranged below the proportioning materials door 9, weigh hopper 10 with draw or pressure sensor 12 is connected as batching electronic scale, the sensor signal lines of batching electronic scale is connected with controller 6.
When beginning to prepare burden, Programmable Logic Controller 6 output control signals drive magnetic valve 4 work, compressed air by P through B to cylinder, make the cylinder action, open batching door 9 and begin batching, when ingredients by weight soon reaches desired value, Programmable Logic Controller 6 output control signals drive magnetic valve 4 actions, compressed air by P through A to cylinder, make cylinder 2 actions, close batching door 9, the cylinder exhaust is finished to A through the P of magnetic valve 5 to S through the B of magnetic valve 4 again, when cylinder 2 moves to switch 3 positions, Programmable Logic Controller output control signal drives magnetic valve 5, turn-offs the exhaust outlet of cylinder 2 and makes compressed air make cylinder stop action through the B of magnetic valve 5 to P, and the aperture of batching door is reduced to desired location, the supplied materials speed of material is reduced, reached the purpose that improves proportioning accuracy, when ingredients by weight reached desired value, controller output control signal drove magnetic valve 5 and makes the cylinder action, close the batching door fully, batching finishes.
