Description
Technical field
The utility model relates to material supply apparatus technical field, particularly relates to a kind of powder metering device for filling.
Background technology
In Modern Packaging Machinery, load transfer device helical feed and system play very important effect.In the industrial production; often can use packaging machine with filled screw and filling and packing is carried out to powder and granule shape material; this kind of screw feeder mainly comprises a support; hopper and splicing funnel is had at support; be connected by delivery pipe between hopper with splicing funnel; be provided with screw rod in this delivery pipe, and screw rod and a motor keep being in transmission connection.But screw rod is typically provided to the screw rod that pitch is equal, base diameter is equal, this screw rod exist in package packing machine blanking uneven, leak material, unclean, measure the problems such as inaccurate.
Utility model content
The utility model in order to solve screw rod unclean in package packing machine, measure inaccurate problem, provide a kind of powder metering device for filling, this device screw rod is set to Variable pitch screw, this variable pitch screw has excellent performance, ensure the homogeneity of blanking, anti-leak-stopping material, has easy to clean, measures advantage accurately.。
The required technical matters solved of the utility model can be achieved through the following technical solutions:
A kind of powder metering device for filling, comprise servomotor, feeding port, screw rod installation sleeve, hopper, screw rod, valve, delivery piping, feed opening, microcontroller, material enters into hopper from feeding port, described screw rod is fixed on the main shaft of described servomotor by screw rod installation sleeve, the below of described screw rod is delivery piping, delivery piping is provided with valve, and the below of valve is provided with feed opening, and described microprocessor control servomotor runs.
Further, described microcontroller is PLC.
Further, described hopper is provided with hopper handle.
Further, described screw rod is Variable pitch screw.
Further, described Variable pitch screw is divided into three sections.
Further, the first paragraph of described Variable pitch screw is for becoming accelerating sections.
Further, the second segment of described Variable pitch screw is wait accelerating sections.
Further, the accelerating sections such as the 3rd Duan Wei of described Variable pitch screw.
The utility model beneficial effect is: a kind of powder metering device for filling, and screw design becomes Variable pitch screw, and variable-distance screw rod is three sections of Variable pitch screws, variable-distance screw rod has excellent performance, ensures the homogeneity of blanking, anti-leak-stopping material, have easy to clean, measure advantage accurately.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the utility model metering filling device structural representation.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in composition graphs 1, realize the utility model.A kind of powder metering device for filling, comprises servomotor 1, feeding port 2, screw rod installation sleeve 3, hopper 4, hopper handle 5, screw rod 6, valve 7, delivery piping 8, feed opening 9, PLC 10.
During concrete enforcement, material enters into hopper from feeding port, screw rod is fixed on the main shaft of servomotor by screw rod installation sleeve, servomotor spindle rotarily drives bolt rotary, the below of screw rod is delivery piping, delivery piping is provided with valve, and the below of valve is provided with feed opening, and microprocessor control servomotor runs.Microcontroller can be PLC.The rotation feed of screw rod is by servomotor to provide power, between the two by synchronously bringing transferring power, accurately can control the rotating cycle of screw rod like this, thus improves the precision of feed.The control signal of screw rod rotating cycle, by the gravimetric value of PLC according to setting, obtains corresponding control wave as calculated afterwards to servomotor, then drives screw rod to rotate the process of each filling feed by servomotor.Screw rod is Variable pitch screw, and Variable pitch screw is divided into three sections, and the first paragraph of Variable pitch screw, for becoming accelerating sections, becomes accelerating sections and causes the precipitous vibrations of screw rod to reduce when material enters screw rod; Second segment, for waiting accelerating sections, waits accelerating sections to be that screw rod extrudes material, makes intergranular even density, ensure the accuracy of Weighing; 3rd section is constant speed section, waits accelerating sections when value of weighing is close to preset value, and servomotor drives screw rod crawl, and ensure the homogeneity of blanking, anti-leak-stopping material, has easy to clean, measures advantage accurately.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
