The forcing press automatic feeding system
The utility model relates to the feeding device in the forcing press pressing process, especially relates to a kind of forcing press automatic feeding system.
In forcing press compacting powder (particulate material) technical process (for example suppressing refractory brick), at first need in mould, to add the raw material of some, the moulding of exerting pressure then.Machine (particularly friction press) spatial constraints and influences such as raw material easily lump, bonding, variable density owing to be stressed are difficult for realizing auto feed.Adopt hand stock mostly, finish the work of forcing press feeding.Hand stock one is that labor strength is big, the 2nd, and charging precision is subjected to factor affecting such as operator's quality, sense of responsibility big, is difficult to accomplish accurate unanimity.
Summary of the invention
The utility model purpose is to provide a kind of charging precision height, advantages of simplicity and high efficiency forcing press automatic feeding system.
For achieving the above object, the utility model can be taked following technical proposals:
Forcing press automatic feeding system described in the utility model, comprise the feed bin that has the charging and discharging mouth, below described feed bin discharging opening, be provided with conveying auger, below the discharging opening of described conveying auger, be provided with the weighing bucket that places on the electronic scale by drive power source; Be provided with the feeding hopper that drives by conveying mechanism in the feed bin student side of described weighing bucket.
The utility model advantage is to replace hand stock, reduces the operating personnel, reduces production costs; The weighing precision height, error is little; Wide accommodation can be adjusted weighting set value at any time, is used for the needs of weighing Different Weight; And it is big to overcome manual weighing's error, and for refractory brick, substance, body are close stable, thereby enhance productivity.During use, the material in the feed bin enters the weighing bucket of below by conveying auger, install electronic scale additional under the weighing bucket, the instruction of sending by PLC is when the input material reaches setting value, conveying auger stops operating, the feed bin door of weighing bucket is opened then, and material is put into the feeding hopper, passes through conveying mechanism, material in the feeding hopper is sent in the mould, whole process is controlled with PLC, realizes circulation automatically, allows heavy, dull hand stock become the advantages of simplicity and high efficiency automation process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, forcing press automatic feeding system described in the utility model, comprise the feed bin 1 that has the charging and discharging mouth, below described feed bin 1 discharging opening, be provided with conveying auger 2, be provided with the weighing bucket 4 that places on the electronic scale 3 below the discharging opening of described conveying auger 2 by drive power source; Below the feed bin door 5 of described weighing bucket 4, be provided with the feeding hopper 7 that drives by conveying mechanism 6.Material in the feed bin 1 is by conveying auger 2, enter the weighing bucket 4 of below, weighing bucket installs electronic scale 3 additional 4 times, by the instruction that PLC sends, when the input material reached setting value, conveying auger 2 stopped operating, the feed bin door 5 of weighing bucket 4 is opened then, material is put into feeding hopper 7,, the material in the feeding hopper 7 is sent in the mould 8 by conveying mechanism 6.
