Detailed description of the invention
For making this utility model solve the technical problem that, the technical scheme that uses and the technique effect that reaches more
Clear, 1 to Fig. 3 further illustrated of the present utility model by detailed description of the invention below in conjunction with the accompanying drawings
Technical scheme.
Referring to figs. 1 to Fig. 3, embodiment of the present utility model provides a kind of charging device, including for quickly
The king bolt carrier 1 that feeds intake, for the minor spiral carrier 2 accurately fed intake, biography that material metage is weighed
Sensor 7 and signal control king bolt carrier 1 and minor spiral carrier 2 according to LOAD CELLS 7 rotate
Control device 8, the diameter of the blade of king bolt carrier 1 is more than the diameter of blade of minor spiral carrier 2.
King bolt carrier 1 rate of feeding is fast, and minor spiral carrier 2 rate of feeding is easy to control slowly, can reach
In high precision.The material cast is weighed by LOAD CELLS 7, and sends signal to control device 8,
When feeding intake, after material adds from storage tank 12, control device 8 controls king bolt carrier 1 and quickly feeds intake,
When weight of material reaches the first preset value, control king bolt carrier 1 and stop operating, minor spiral carrier 2
Rotation feeds intake, until it reaches the second preset value, then controls the intermittent rotation of minor spiral carrier 2 so that thing
Material weight reaches final goal value.King bolt carrier 1 and minor spiral carrier 2 are combined by charging device,
Can realize quickly feeding intake, the high-precision requirement of the weight of material can be reached again.Owing to being launched from material,
LOAD CELLS weighs, to control device send signal control the process of auger conveyor operating need one section time
Between, this period is referred to as lag time, so when high-precision material is thrown in, when reaching high-precision thing
After material is launched, within lag time, throw in again some materials so that overall weight of material exceeds standard,
Do not reach required high accuracy, and in the present embodiment, feed intake final stage, control minor spiral carrier 2
As the buffer of lag time, intermittent rotation, can determine that material is also in the intermittent time stopped operating
Miss the mark value is further continued for feeding intake, can with Step wise approximation desired value until reaching required weight, and by
In the problem that lag time is brought.As a example by the final goal value of weight of material is as 100kg, pre-by first
If value is set to 92kg, the second preset value is set to 98kg, and when feeding intake, material adds from storage tank 12
After, control device 8 controls king bolt carrier 1 and quickly feeds intake, when LOAD CELLS 7 detects material weight
When amount reaches 92kg, control device 8 controls king bolt carrier 1 and stops operating, minor spiral carrier 2 turns
Moving and feed intake, weight of material continues rising and reaches 98kg, then controls the intermittent rotation of minor spiral carrier 2, false
If lag time is 0.5 second, controls minor spiral carrier 2 and rotate 0.3 second, stop constantly circulation in 0.7 second,
The most constantly detect weight of material, until it reaches 100kg, stop minor spiral carrier 2 and rotate.Logical
Cross this kind of feeding mode, the problem that can avoid exceeding standard due to the weight of material brought lag time.
In the present embodiment, whether auger conveyor is positioned at same discharge tank there is no impact to the precision that feeds intake, therefore,
King bolt carrier 1 and minor spiral carrier 2 can be located at same discharge tank 3;Or king bolt carrier 1 sets
In the first discharge tank, minor spiral carrier 2 is located in the second discharge tank.Charging device also includes for connecing
Receiving the material-receiving device 6 of material, material-receiving device 6 is positioned at king bolt carrier 1 and the discharging of minor spiral carrier 2
The lower section of the discharging opening of tank 3.Optionally, the discharge tank 3 of king bolt carrier 1 and minor spiral carrier 2
Discharging opening connect have flexible pipe 5, discharging opening by flexible pipe 5 by material throw in down, it is not necessary to the dress of lower section
Put such as material-receiving device 6 Hard link, and disturb the weighing sensor 7 measurement to material.Charging device also includes
Weighing platform 10, weighing platform 10 carries material-receiving device 6, and LOAD CELLS 7 is positioned at bottom material-receiving device 6 direct
Detect the weight of material-receiving device 6, or the one end being connected to weighing platform 10 show that splicing fills after conversion indirectly
Put the weight of 6, thus learn the weight of material in material-receiving device 6.
In the present embodiment, charging device also includes driving means 4, for making overall structure simple, and driving means
One end of the 4 close charging apertures being positioned at king bolt carrier 1 and minor spiral carrier 2, drives king bolt conveying
Device 1 and minor spiral carrier 2 rotate.Driving means 4 can such as pass through motor there to be various structures form
With Timing Belt or motor and chain etc., the present embodiment uses motor 41 and decelerator 42, controls reliable,
The input of decelerator 42 connects motor 41, and outfan connects king bolt carrier 1 and minor spiral carrier 2.
For simplifying structure further, between king bolt carrier 1 and driving means 4, it is provided with the first one-way clutch,
Be provided with the second one-way clutch between minor spiral carrier 2 and driving means 4, the first one-way clutch with
The locking of the second one-way clutch is in opposite direction, by the one-way clutch that two lockings are in opposite direction, only needs
Want the rotating of a driving means 4 can control corresponding augur, it is not necessary to two drive dress
Put and drive augur respectively.
In the present embodiment, for meeting the different accuracy requirement that feeds intake, charging device also includes input equipment 9, defeated
Entering equipment 9 and electrically connect with controlling device 8, staff can be according to the required precision that feeds intake by corresponding parameter
It is input to control in device 8.Charging device operationally can shake, for prevent the material of discharge outlet due to
Vibrations are dropped and are impacted the whole precision that feeds intake, king bolt carrier 1 and/or minor spiral carrier 2
The discharging opening of discharge tank 3 is provided with check valve 11, and when auger conveyor shuts down, check valve 11 can be certainly
Dynamic closedown prevents material from dropping.
