Weighing type bulking mechanism
Technical field
This utility model relates to filling liquid technical field, particularly relates to a kind of Weighing type bulking mechanism.
Background technology
It is required for carrying out filling liquid, such as beverage, liquid detergent, disinfectant solution etc. to be required for liquid quantitative in a lot of fields
Pouring in bottle and encapsulate, the most traditional filling mechanism generally uses piston type fill, promotes piston to backhaul by cylinder
The dynamic fill realizing material, the shortcoming of piston type racking machine is that filling accuracy is the highest, if sucking bubble, charging aperture in plunger shaft
Place's check valve leakage, cylinder form error and filling accuracy all can be caused to decline, and need the liquid of accurate measurement especially for some
Body, if filling accuracy deficiency can cause fill amount excessive or too small, fill amount is excessive to be caused waste and increases cost, fill amount
The least labelled amount causing liquid actual amount to be less than on bottle, does not meets sale requirement.
Utility model content
This utility model is in order to overcome filling machine filling accuracy of the prior art poor, it is difficult to meet high accuracy fill demand
Deficiency, it is provided that a kind of filling accuracy is high, can meet the Weighing type bulking mechanism of fill demand in high precision.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of Weighing type bulking mechanism, including base, described base is provided with electronic scale, and the end face of described electronic scale is provided with
Pallet, the both sides that base is positioned at electronic scale are provided with vertical connecting rod, are provided with crossbeam between the upper end of described connecting rod, described
Crossbeam be provided with feed tube, the lower end of described feed tube is provided with vertical drain pipe, and the outer sheath of described drain pipe is provided with to be stretched
The draw, the lower end of described telescoping tube extends and forms elongated regulation pipe, and the upper end of described regulation pipe is provided with electrically-controlled valve, described flexible
The outside of pipe is provided with auricle, and auricle is provided with slide opening, and described crossbeam is provided with the guide post passing vertically through slide opening, described horizontal stroke
Beam is provided with lift cylinder, and the axle head of described lift cylinder is fixing with one of them auricle to be connected.Mechanical hand is also set up on base,
Bottle is moved on pallet by mechanical hand, and bottleneck is positioned at the underface of regulation pipe, and lift cylinder action drives telescoping tube to decline, carefully
Long regulation pipe stretches in bottleneck, and electrically-controlled valve opens filling liquid in bottle, when electronic scale detects the weight of bottle and liquid
After amount reaches rated weight, electrically-controlled valve is closed, and lift cylinder drives telescopic to rise, and regulation pipe departs from bottleneck, thus completes
The accurate fill of bottle, stretches in bottleneck owing to regulating the upper end of pipe during fill, thus greatly reduces liquid and outside air
Contact, prevents the antibacterial in air from entering in liquid.
As preferably, the lower end of described regulation pipe is provided with cloth liquid set, and described cloth liquid set is threadeded between regulation pipe,
Described cloth liquid set is drum type, and the side of described cloth liquid set is uniformly provided with some liquid injection holes.After liquid enters cloth liquid set, from side
Liquid injection hole at be discharged in bottle, the liquid jet discharged at liquid injection hole, to bottleneck (bottle) inwall, thus reduces liquid
The impact interference to electronic scale, fill is more accurate.
As preferably, between described cloth liquid set and regulation pipe, it is provided with drainage screen.Particulate matter in liquid is carried out by drainage screen
Filter.
As preferably, the upper side of described regulation pipe is provided with air inlet, and the outer end of described air inlet is provided with electromagnetic valve, institute
State and at the inlet end of electromagnetic valve, be provided with air filtration set.When cloth liquid extracts liquid, electromagnetic valve is closed, when electronic scale detects
When reaching the 99% of rated weight to bottle and liquid weight, electrically-controlled valve is closed, owing to the upper end closed of regulation pipe does not has air to enter
Entering, the liquid in regulation set will not flow, and now opens electromagnetic valve, and outside air enters the liquid in regulation set, in cloth liquid set
Flowing into slowly in bottle, now flow rate of liquid is very slow, flow is little, drop is little, and the kinetic energy that liquid falls is to electronic scale almost
There is no any impact, when electronic scale detects that weight is equal to rated weight, closed electromagnetic valve, the now weight of liquid in bottle
With rated weight and close.
Therefore, it is high that this utility model has filling accuracy, can meet the beneficial effect of high accuracy fill demand.

Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
A kind of Weighing type bulking mechanism as depicted in figs. 1 and 2, including base 1, base is provided with electronic scale 2, electronic scale
End face be provided with pallet 3, the both sides that base is positioned at electronic scale are provided with vertical connecting rod 4, are provided with between the upper end of connecting rod
Crossbeam 5, crossbeam is provided with feed tube 6, and the lower end of feed tube is provided with vertical drain pipe 7, and the outer sheath of drain pipe is provided with flexible
Pipe 8, the lower end of telescoping tube extends and forms elongated regulation pipe 9, and the upper end of regulation pipe 9 is provided with electrically-controlled valve 10, the outside of telescoping tube
Being provided with auricle 11, auricle is provided with slide opening, and crossbeam is provided with the guide post 12 passing vertically through slide opening, and crossbeam is provided with lift cylinder
13, the axle head of lift cylinder 13 is fixing with one of them auricle to be connected;
As it is shown on figure 3, the lower end of regulation pipe 9 is provided with cloth liquid set 14, threaded between cloth liquid set with regulation pipe, cloth liquid set
In drum type, the side of cloth liquid set is uniformly provided with some liquid injection holes 15, is provided with drainage screen 16 between cloth liquid set and regulation pipe;Regulation pipe
The upper side of 9 is provided with air inlet 17, and the outer end of air inlet is provided with electromagnetic valve 18, is provided with air filtration at the inlet end of electromagnetic valve
Set 19.
Also setting up mechanical hand on base, bottle 20 is moved on pallet by mechanical hand, and bottleneck is positioned at the underface of regulation pipe,
Lift cylinder action drives telescoping tube to decline, and elongated regulation pipe stretches in bottleneck, and electrically-controlled valve opens filling liquid in bottle,
After electronic scale detects that the weight of bottle and liquid reaches the 99% of rated weight, electrically-controlled valve is closed, and electromagnetic valve is opened, extraneous
Air enters in regulation set, and the liquid in cloth liquid set flows in bottle slowly, and now flow rate of liquid is very slow, flow is little, fall
Difference is little, and electronic scale is almost no impact by the kinetic energy that liquid falls, when electronic scale detects that weight is equal to rated weight,
Closed electromagnetic valve, the now weight of liquid and rated weight and close in bottle, it is believed that actual weight is equal to specified heavy
Amount.Therefore, it is high that this utility model has filling accuracy, can meet the beneficial effect of high accuracy fill demand.
