Compared with the prior art, the utility model has the advantages of simple structure, high precision, wide filling range, etc.
Description
Technical field
The utility model relates to the control mechanism of metering cylinder can, relates in particular to a kind of control mechanism that is used for the metering cylinder can of liquid material.
Background technology
The driver train that existing metering cylinder bulking system adopts mainly contains two kinds of forms: crank-link mechanism, air cylinder driven mechanism.
Crank-link mechanism is traditional classical mechanism, is directly dragged by motor.Its shortcoming is: 1. volume is bigger, complex structure, and crank, connecting rod and slide block are non-standard component, need machinework; 2. change the can amount by the eccentric throw of adjusting slide block, so adjustment inconvenience and adjusting accuracy are not high; 3. can setting range is little, for adapting to large-scale can, needs conversion metering cylinder cylinder diameter; 4. can kinematic velocity curve is a sinusoidal form, and is fixing non-adjustable.
Air cylinder driven mechanism need dispose the upper-lower position sensor, and its shortcoming is: though 1. cylinder is a gauge member, need annexes such as configuration source of the gas, volume is bigger; 2. can amount adjustment realizes by sensor sensing position about changing, so resolution is not high, under the situation of pressure variation, directly influences filling accuracy; 3. can setting range is little, for adapting to large-scale can, needs conversion metering cylinder cylinder diameter; 4. can kinematic velocity curve is a form of straight lines, and is fixing non-adjustable.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the shortcoming that above-mentioned prior art exists a kind of simple in structure, precision is high, can realize the metering cylinder filling apparatus of wide-range can.
The purpose of this utility model can be achieved through the following technical solutions: a kind of metering filling control mechanism, it is characterized in that, and comprise stepping motor, screw mandrel, piston, metering cylinder body, combine valve, controller; Described stepping motor is connected with an end of screw mandrel, the other end of described screw mandrel is connected with piston, described screw mandrel, piston are located in the metering cylinder body, the action of described controller control step motor and combine valve, described stepping motor drive screw mandrel, piston is reciprocating in the metering cylinder body.
Described combine valve is the rotating circular valve that is driven by rotating machine.
The basic controlling unit of described controller for constituting by actuator and chip microprocessor.
Compared with prior art, the utlity model has following advantage:
1. save the necessary annexes such as compressed air source of pneumatic system, only need single phase alternating current power supply to move, adopt gauge member, amount of machining is little, and is simple in structure, and volume is little;
2. stepping motor matches with leading screw, can reach very high displacement accuracy, thereby has improved filling accuracy greatly, cylinder diameter that can the conversion metering cylinder when different range can;
3. stepping motor can be save position transduser as the power element of open loop control system, and can change the can amount easily, satisfies the needs of wide-range can;
4. give full play to the effect of microprocessor in the controller, the soft or hard combination, electromechanical is made up rotation direction, speed and the corner of stepping motor, just can form different can curve movements, to satisfy different filling process requirements.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of embodiment of metering filling control mechanism, it comprises stepping motor 1, screw mandrel 2, piston 3, metering cylinder body 4, combine valve 5, controller 6; Described stepping motor 1 is connected with an end of screw mandrel 2, the other end of described screw mandrel 2 is connected with piston 3, described screw mandrel 2, piston 3 are located in the metering cylinder body 4, the action of described controller 6 control step motors 1 and combine valve 5, described stepping motor 1 drives screw mandrel 2, piston 3 is reciprocating in metering cylinder body 4.Described combine valve 5 is the rotating circular valve that is driven by the SXCT rotating machine.The basic controlling unit of described controller 6 for being made of ST-4HB06 actuator and MCS-51 chip microprocessor can be according to the parameter of setting, the motion of control step motor 1 and combine valve 5.All controlled device 6 controls of the rotation direction of stepping motor 1, speed and corner, all parameters all can be set by the man-machine interface operating panel of controller 6 by the operator; When the stepping motor 1 of controlled device 6 controls rotates, by bonded assembly screw mandrel 2 coaxial with it, drag piston 3 back and forth movement in metering cylinder body 4, under the cooperation of combine valve 5 (also controlled device 6 controls), finish suction and can the interior material of storage tank (figure does not show).The can amount is directly proportional with the compression stroke Δ L of piston 3, and also the rotational angle with stepping motor 1 is directly proportional.
