Abstract
A kind of automatic small proportioning device, it includes scale hooper, and weighing bucket frame is on rotary support frame；Weighing sensor is set in the bottom of scale hooper, and weighing sensor sends the weight signal of collection to controller, and controller exports trigger command into cylinder, and the cylinder rod of cylinder is stretched out and jacks up the side of scale hooper.The present invention uses above-mentioned technical proposal, has the advantage that：1. the power resources of discharging device do not have external force to act on scale hooper outside meausring apparatus during weighing, influence of the conventional discharging device power line to weighing precision is completely eliminated.2. feed, it is 30 ~ 45 ° that scale hooper rotates inclination angle along bearing pin, material is flowed completely out scale hooper.
Description
Technical field
The present invention relates to a kind of proportioning device, more particularly to a kind of automatic small proportioning device.
Background technology
With the progress of the development science and technology of society, many scripts are more and more replaced by the work being accomplished manually by machine
Generation.In grinding wheel, brake block manufacturing, the progress of manufacturing process has also required that corresponding control device is matched.In sand
In the production process for taking turns piece, brake block, most process has been achieved with mechanization, automation, has charging process only substantially
It is accomplished manually.
The weight of grinding wheel and brake block is relatively light, and conventional is general between tens grams to one or two kilogram, so plus
Requirement during material to absolute error is higher.Weigh one kilogram, it is allowed to 5 grams of error, weigh within 100 grams, it is allowed to which error can not be big
In 1 gram, such index seems not high, is converted into precision and is even below 1%, but runs, vibrates, dust in industrial settings, very
Weighing results can be all had influence on to breathing, so being extremely difficult to the scope of absolute error requirement.
Vibration effect can add damping device, and wind and dust can add locking device, but the action of discharging device necessarily needs
Power is wanted, either pneumatically, is surged or electronic, the transmission of power must be by pipeline, object that pipeline will be external with scale
It is connected, power will be acted by being connected, and have active force to will result in weighing error, mistake is produced when this discharging device power transmits
The error of difference can not still overcome, and this problem constrains the application and development automatically controlled in small dosing device, thousands of
Platform grinding wheel, brake slice assembly line also rely on and are accomplished manually charging.
The content of the invention
For deficiency of the prior art, the present invention provides a kind of scale hooper during weighing not to be influenceed, thoroughly by external force
Eliminate the automatic small proportioning device that discharging device power line influences on weighing precision.
The technical solution adopted for solving the technical problem of the present invention is：A kind of automatic small proportioning device, it includes scale hooper,
Weighing bucket frame is on rotary support frame；Weighing sensor is set in the bottom of scale hooper, weighing sensor is by the weight of collection
Signal is sent to controller, and controller exports trigger command into cylinder, and the cylinder rod of cylinder is stretched out and jacks up the side of scale hooper.
Described rotary support frame includes the bearing pin for being symmetricly set on scale hooper both sides, and bearing pin is connected with supporting vertical plate.
Connecting plate is set between two described bearing pins.
The weighing sensor is located at the bottom of supporting vertical plate.
Described cylinder is arranged on the base of weighing sensor.
Described cylinder is roller type stop cylinder.
When the roller type stop cylinder does not work, the distance between the roller and scale hooper on cylinder cylinder rod top be 0.5 ~
1.5mm。
The scale hooper along bearing pin rotate when, angle of inclination and horizontal direction are 30 ~ 45 ° downwards.
The present invention uses above-mentioned technical proposal, has the advantage that：
1. the power resources of discharging device do not have external force to act on scale hooper outside meausring apparatus during weighing,
Completely eliminate influence of the conventional discharging device power line to weighing precision.
2. feed, it is 30 ~ 45 ° that scale hooper rotates inclination angle along bearing pin, material is flowed completely out scale hooper.
Brief description of the drawings
Fig. 1 is the front view of structure of the present invention.
Fig. 2 is the top view of structure of the present invention.
Embodiment
As shown in figure 1, a kind of automatic small proportioning device, it includes scale hooper 1, the frame of weighing bucket 1 on rotary support frame,
Rotary support frame includes the bearing pin 2 for being symmetricly set on the both sides of scale hooper 1, sets connecting plate 8 between two bearing pins 2, connecting plate 8 is used for solid
To determine and keep the balance of scale hooper 1, bearing pin 2 is connected with supporting vertical plate 3, and the bottom of supporting vertical plate 3 is provided with weighing sensor 6,
Cylinder 5 is provided with the base 7 of weighing sensor 6.
When scale hooper 1 plus good material, the weighing sensor 6 of the bottom of scale hooper 1 sends the weight signal of collection to control
Device processed, controller export trigger command into cylinder 5, and the cylinder rod of cylinder 5 is stretched out, and roller 4 jacks up the side of scale hooper 1, is weighed
Bucket 1 is rotated along bearing pin 2, and the material in scale hooper 1 flows out scale hooper 1 under gravity, and then the cylinder rod of cylinder 5 is withdrawn,
Cylinder rod is disengaged and kept at a distance with scale hooper 1.When roller 4 jacks up the side of scale hooper 1, scale hooper 1 is along the angle of rotation of bearing pin 2
Degree can be any angle between 30 °, 40 °, 45 ° or 30 ~ 45 °；Material in scale hooper 1 is under gravity
Flow out scale hooper 1, then the cylinder rod of cylinder 6 is withdrawn, the spacing that cylinder rod and scale hooper 1 disengage holding can be 0.5mm,
Arbitrary value between 1.0mm, 1.5mm or 0.5 ~ 1.5mm.
The automatic small proportioning device that the present invention uses, discharging device power resources in proportioning device in itself, not by outer masterpiece
With thoroughly eliminating the influence of the symmetrical accuracy of measurement of weighing process exterior power, reached the scope for weighing the requirement of process absolute error.
