Abstract
The invention relates to a quantitative feeding machine used for raw material distribution. The quantitative feeding machine comprises a discharging hopper, a driving roller, a belt, a feeding hopper, a driven roller, supporting rollers, a machine frame, a driving motor and a weighing structure. The quantitative feeding machine is characterized in that the feeding hopper and the discharging hopper are respectively arranged on the machine frame; the belt is arranged at the bottom of the feeding hopper and driven by the driving motor arranged on a driving roller shaft; the lower portion of the belt is provided with the weighing structure and the supporting rollers. The quantitative feeding machine can avoid the situation that unbalance loading of the belt and materials affects weighing accuracy, performance of the feeding machine is greatly improved, the feeding machine can be suitable for various environments, and the feeding machine operates safely and reliably and is beneficial to being popularized and used.
Description
Technical field
The present invention relates to a kind of feed proportioning equipment, particularly a kind of constant feeder for feed proportioning.
Background technology
Constant feeder is bulk material to be carried out to the ideal equipment of consecutive weighings feed, the weighing mode of prior art is to adopt weighing frame, single LOAD CELLS is arranged on scale frame side, this weighing mode, not only the force-transmitting ring joint is many, and, due to the impact of belt, material, be easy to cause unbalance loading and affect weighing precision.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of constant feeder, more with force-transmitting ring joint in the solution prior art, the problem that system accuracy is not high.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of constant feeder, comprise hopper, drive roll, belt, elevating hopper, passive cylinder, carrying roller, frame, drive motor and weighing structure, described elevating hopper, described hopper are arranged on respectively on described frame; Described belt is arranged on the elevating hopper bottom, and described belt is driven by the described drive motor be arranged on the drive roll axle; Described belt bottom is provided with described weighing structure and a plurality of described carrying roller.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described weighing structure comprises LOAD CELLS and weighing carrier roller, and described weighing carrier roller axle head is arranged on the front end connection of described LOAD CELLS.
Further, described weighing structure comprises two LOAD CELLS.
Further, also comprise tachogenerator, described tachogenerator is arranged on the spindle nose of passive cylinder.
Further, described tachogenerator comprises speed measuring coder and the housing that is arranged on the speed measuring coder outside.
The invention has the beneficial effects as follows: the present invention has adopted the weighing mode of two LOAD CELLS, can avoid belt, material unbalance loading to impact impact to weighing precision, not only the feeder performance is largely increased but also can adapts to various environment, safe and reliable to operation, be conducive to promoting the use of of constant feeder.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In accompanying drawing, the parts of each label representative are as follows:
1, hopper, 2, drive roll, 3, belt, 4, weighing carrier roller, 5, carrying roller, 6, elevating hopper, 7, passive cylinder, 8, frame, 9, LOAD CELLS, 10, tachogenerator, 11, drive motor
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only be used to explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, the constant feeder of the present embodiment, comprise hopper 1, drive roll 2, belt 3, elevating hopper 6, passive cylinder 7, carrying roller 5, frame 8, drive motor 11 and weighing structure, and described elevating hopper 6, hopper 1 are arranged on respectively on described frame 8; Described belt 3 is arranged on elevating hopper 6 bottoms, and described belt 3 is driven by the described drive motor 11 be arranged on drive roll 2 axles; Described belt 3 bottoms are provided with described weighing structure and a plurality of described carrying roller 5.Described weighing structure consists of weighing carrier roller 4 and two LOAD CELLS 9, described weighing carrier roller 4 axle heads are arranged on the front end connection of described LOAD CELLS 9, when weighing carrier roller bore weight, LOAD CELLS was stressed, gravitational cue can be converted to electric signal output.
The constant feeder of the present embodiment, also comprise tachogenerator 10, and described tachogenerator 10 comprises speed measuring coder and the housing that is arranged on the speed measuring coder outside, and described tachogenerator 10 is arranged on the spindle nose of passive cylinder 7.When passive cylinder 7 rotates a week, will drive speed measuring coder 10 and rotate a week, send 1000 pulses, the length of the belt operation that each pulse representative is fixing.The weighing-up wave of LOAD CELLS output amplifies through amplifier, then through signal converter, converts digital quantity to and be transported to CPU element; The LOAD CELLS output pulse signal, be transported to CPU after shaping; Each impulse singla causes that CPU interrupts once, and the signal converter sampled value is deducted to zero point value again divided by after coefficient of ranger, adding up, and calculates instant flow rate value and aggregate-value.
The present invention has adopted the weighing mode of two LOAD CELLS, can avoid belt, material unbalance loading to impact impact to weighing precision, not only the feeder performance is largely increased but also can adapts to various environment, safe and reliable to operation, is conducive to promoting the use of of constant feeder.
Above are only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
