Abstract
The utility model discloses a kind of screw feeder, comprise casing, transmission shaft, screw shaft, helicallobe, inlet point and discharging opening, described helicallobe is arranged on described screw shaft, described screw shaft is connected with described transmission shaft, described discharge outlet is provided with spiral and claims, the bottom that described spiral claims is provided with LOAD CELLS, and described LOAD CELLS is connected with batching controller, weighing controller respectively, and described LOAD CELLS is connected with frequency converter again.The purpose of this utility model is to provide the high screw feeder of a kind of weighing precision.
Description
Technical field
The utility model relates to feeder.Be specifically related to screw feeder.
Background technology
The weighing mode of existing screw feeder just adopts weighing frame, and single LOAD CELLS is arranged on scale frame side, this weighing mode, and not only force-transmitting ring joint is many, and due to the impact of belt material, easily causes unbalance loading and affect weighing precision.
Utility model content
The purpose of this utility model is to provide the high screw feeder of a kind of weighing precision.
In order to achieve the above object, the utility model has following technical scheme:
Screw feeder of the present utility model, comprise casing, transmission shaft, screw shaft, helicallobe, inlet point and discharging opening, described helicallobe is arranged on described screw shaft, described screw shaft is connected with described transmission shaft, described discharge outlet is provided with spiral and claims, the bottom that described spiral claims is provided with LOAD CELLS, and described LOAD CELLS is connected with batching controller, weighing controller respectively, and described LOAD CELLS is connected with frequency converter again.
Further, the gap between described helicallobe is 0.5-1.0mm.
Further, between described transmission shaft and described screw shaft be pinned connection.
Further, described inlet point, discharge outlet are provided with connection box, described inlet point, are equipped with gate between discharging opening and connection box, and gate is connected with cylinder.
Owing to taking above technical scheme, the utility model has the advantage of:
The utility model, firm scale body design, ensure that steady operational status, double-spiral structure ensure that the uniform feeding of helix balance, gap between screw is little, between 0.5 ~ 1.0mm, overcomes backflow and alters material problem, pipe internal clearance attachment material, high-precision LOAD CELLS, ensures the reliable reasonably pressure feeding spiral project organization of accurate measurement, ensure that spiral afterbody not flash, do not harden, and be convenient to replacing and the maintenance of spiral, material sends into the discharging opening of helix balance through spiral impeller feeder, time material is by helix balance process, namely the weighting apparatus be installed on below helix balance completes the detection to weight of material, LOAD CELLS transfers the voltage signal being proportional to load to electric signal and gives batching controller, simultaneously by material fltting speed impulse singla input batching controller, two kinds of signals carry out after signal transacting through batching controller, draw actual material instant flow rate and cumulative weight value, weighing controller goes this instant flow rate to compare with the mass flow set amount of technological requirement again, correction is exported after drawing difference, and pass through the output speed of Frequency Converter Control spiral impeller feeder, actual mass flow and setting value are consistent.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, casing 2, inlet point 3, transmission shaft 4, screw shaft 5, helicallobe 6, spiral claim 7, weighing controller 8, frequency converter 9, batching controller 10, LOAD CELLS 11, connection box 12, cylinder 13, gate 14, discharging opening
Detailed description of the invention
Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.
See Fig. 1, the utility model is screw feeder of the present utility model, comprise casing 1, transmission shaft 3, screw shaft 4, helicallobe 5, inlet point 2 and discharging opening 14, described helicallobe 5 is arranged on described screw shaft 4, described screw shaft 4 is connected with described transmission shaft 3, described discharging opening 14 place is provided with spiral and claims 6, described spiral claims the bottom of 6 to be provided with LOAD CELLS 10, described LOAD CELLS 10 is connected with batching controller 9, weighing controller 7 respectively, and described LOAD CELLS 10 is connected with frequency converter 8 again.Gap between described helicallobe 5 is 0.5-1.0mm.Be pinned connection between described transmission shaft 3 and described screw shaft 4.Described inlet point 2, discharging opening 14 place are provided with connection box 11, described inlet point 2, are equipped with gate 13 between discharging opening 14 and connection box 11, and gate 13 is connected with cylinder 12.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
