Description
Technical field
The present invention relates to a kind of metering and separate loading machine, relate in particular to a kind of metering and separate loading machine feeder.
Background technology
Feeder is one of critical component of metering and separate loading machine, and feeder and type of drive thereof directly have influence on packing precision, output, cleaning and sterilizing and the reliability of metering and separate loading machine.
Metering and separate loading machine of the prior art adopts motor to come drive screw to carry out feed, and following shortcoming is specifically arranged:
The start and stop of motor and acceleration and deceleration all need the regular hour, therefore realizing delivery rate through speed governing and forming in the control system of closed loop, tend to have influence on the precision of metering, output; Screw rod processing and matching requirements are higher; Drive part complex structure, bulky, complicated structure have also caused problems such as inconvenience and the trouble point height of cleaning and sterilizing, installation and maintenance.
Summary of the invention
The purpose of this invention is to provide that a kind of simple in structure, speed governing is convenient, the accurate metering and separate loading machine feeder of metering.
The objective of the invention is to realize through following technical scheme:
Metering and separate loading machine feeder of the present invention; Comprise the rotation packing valve, the below of said rotation packing valve is provided with bag bundling mechanism, and said rotation packing valve comprises greater trochanter; Be provided with lesser trochanter in the said greater trochanter; Said greater trochanter is coaxial with trochantinian center of gyration, and said trochiterian axle drive shaft is connected with pneumatic actuator, and said trochantinian axle drive shaft is connected with the gas motor.
Technical scheme by the invention described above provides can be found out; Metering and separate loading machine feeder provided by the invention, owing to comprise the rotation packing valve, the rotation packing valve comprises greater trochanter; Be provided with lesser trochanter in the greater trochanter; Greater trochanter is coaxial with trochantinian center of gyration, and trochiterian axle drive shaft is connected with pneumatic actuator, and trochantinian axle drive shaft is connected with the gas motor.Through pneumatic actuator and pneumatic motor driven greater trochanter and the lesser trochanter of pressurized air as power, realize quick feed and accurate feeding respectively, simple in structure, speed governing makes things convenient for, metering is accurate.

Among the figure: 1, source of the gas, 2, solenoid directional control valve, 3, tracheae, 4, the gas motor, 5, the rotation packing valve, 6, electronic weighing balance, 7, pneumatic actuator, 8, bag bundling mechanism.
The specific embodiment
To combine accompanying drawing that the embodiment of the invention is done to describe in detail further below.
Metering and separate loading machine feeder of the present invention, its preferable specific embodiment is as shown in Figure 1:
Comprise the rotation packing valve; The below of said rotation packing valve is provided with bag bundling mechanism; Said rotation packing valve comprises greater trochanter, is provided with lesser trochanter in the said greater trochanter, and said greater trochanter is coaxial with trochantinian center of gyration; Said trochiterian axle drive shaft is connected with pneumatic actuator, and said trochantinian axle drive shaft is connected with the gas motor.
The below of said bag bundling mechanism is provided with electronic weighing balance, and the air feed source of the gas place of the gentle motor of said pneumatic actuator is provided with feed flow control device, and said electronic weighing balance is connected with PLC respectively with feed flow control device.
The present invention adopts pneumatic actuator and air motor to come the driven in rotation packing valve to carry out feed, adopts pressurized air as power.Pneumatic actuator and pneumatic motor starting moment of torsion are bigger, can be with to carry to start; Can be fully loaded with operation continuously for a long time, overload can not produce any damage to air motor; In operational process, can not change because of loading condition changes performance; Can suddenly start, the anxious shutdown is particularly suitable for the occasion of frequent starting, and switching-over is very easy, and the time is short, and rotating speed is fast, and impact is little, and does not need unloaded loads; Simple infinite speed variation, if the compressed-air actuated flow of control, flexible operation; Simple in structure, volume is little, and is in light weight, superpower, and the life-span is long; High-adaptability easy to maintenance, temperature rise is less, can adapt to various harsies environment, can be used for environment to equipment requirements than under the conditions of higher, the zone high like explosive-proof grade; High temperature, high humidity, dust, vibration, the zone of specific (special) requirements such as corrosion; Be fit to very much moise-heat sterilization, the risk of short-circuits of having avoided electro-motor often to face.
Therefore, the present invention's measuring accuracy of having avoided screw feeder complex structure, bulky, speed of response to postpone to cause greatly low, yield poorly and the problem of poor reliability.The fault rate of actuating unit is low in addition, and the life-span is grown and makes the easy to operate and maintainability of whole metering and separate loading machine increase greatly.
The feeder of metering and separate loading machine is replaced to the rotation packing valve; Drive through pneumatic actuator and air motor; And select suitable big or small valve combination according to calculating, through regulating the very easy adjusting of carrying out speed of charge air, guarantee the high-accuracy high-efficiency rate.Have compared with prior art that volume is little, in light weight, simple in structure, speed control principle is simple, the reliability advantages of higher.
The measurement weight of electronic scale; After comparing through PLC controller and setting weight; To the run signal of solenoid directional control valve output pneumatic actuator or air motor, realize drive controlling through controlling compressed-air actuated break-make and direction to pneumatic actuator and gas motor, feed is divided into quick feed and two stages of accurate feeding; The feed stage is accomplished by the greater trochanter that drives through pneumatic actuator fast; The accurate feeding stage is accomplished by the lesser trochanter through the gas motor driven, sets through parameter and confirms big/trochantinian switching time and running frequency, thereby realize the metering of high-speed, high precision.
Specific embodiment:
Aseptic subpackaged machine all adopts the present invention, relies on pneumatic actuator and air motor to come the driven in rotation packing valve to carry out feed.Pass through real-world operation; Proof adopts pneumatic actuator and pneumatic motor driven rotation packing valve to carry out feed; Be significantly improved in measuring accuracy, output, cleaning and sterilizing, aspect stable and improve; And because simple in structure, volume is little, in light weight, the life-span is long, speed control principle is simple etc., the work of having simplified operation greatly and having safeguarded.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
