Abstract
The utility model relates to an anti-bridging hopper which is used for feeding of powder. The anti-bridging hopper comprises a hopper body, wherein a feeding space is enclosed by the hopper body, the feeding space is provided with a discharge outlet, a slope table is arranged in the feeding space and is fixedly connected on the inner wall of the feeding space, the slope table tilts towards the direction of the discharge outlet from the inner wall of the feeding space to form an opening opposite to the discharge outlet, an elastic sack is fixedly arranged at the position of the opening and is provided with two openings, one opening of the elastic sack is in butt joint with the opening of the slope table, and the other opening of the elastic sack is opposite to the discharge outlet. According to the anti-bridging hopper, a bridging phenomenon in the hopper is avoided, and therefore the occurrence of raw material supply break during feeding is avoided, extruding of raw material is stable, and smooth proceeding of production is guaranteed.
Description
Technical field
The utility model relates to a kind of employed anti-bridge formation hopper of material loading that is directed to the relatively poor raw material of powdery, flowing power.
Background technology
Shown in accompanying drawing 1, mechanical equipment often can be used powder raw material when producing, and powder raw material easily forms arch formation during in charging after being added in the hopper.Arch formation refers to that near the powder raw material the hopper discharging opening enters in the machine barrel of hopper bottom, and top powder can not be filled down owing to the reason of extruding timely, thereby causes granular material to make somebody a mere figurehead in hopper as bridge.Address this is that and can manpower pat or knock hopper, but this terms of settlement cures the symptoms, not the disease all the time, very trouble.And arch formation may cause raw material to interrupt, and extrudes unstablely, and impact is produced.
Summary of the invention
The purpose of this utility model provides a kind of anti-bridge formation hopper that prevents that arch formation from producing, avoiding raw material to interrupt.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-bridge formation hopper, be used for the charging of powder, it comprises the hopper body that surrounds the charging space, described charging space has feed opening, described charging is provided with ramp in the space, described ramp is fixedly connected on the inwall in described charging space, described ramp by the inwall in described charging space to the direction inclination of described feed opening and form the oral area relative with described feed opening, described oral area place is fixedly installed the elasticity cloth bag, described elasticity cloth bag has two openings, the oral area of a described opening and described ramp connects, and another described opening is relative with described feed opening.
Preferably, the size of the opening relative with described feed opening of described elasticity cloth bag is greater than the size of described feed opening.
Preferably, described elasticity cloth bag described opening is fixedly connected on the oral area place of described ramp by fixed strip.
Preferably, described fixed strip is soft magnetic stripe.
Preferably, the cross section of described hopper body is circular, and described ramp is that the cross section is circular sloping round platform.
The utility model in use, when powder was filled it up with charging space in the hopper body, sufficient material pressed down and forces the elastical cloth bag to expand, the antagonistic force of elasticity cloth bag impels material toward dirty simultaneously.Along with near the outflow of the material the feed opening, the material at elasticity cloth bag place is pushed by antagonistic force, and reciprocation cycle has been avoided arch formation occurring in the hopper body.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model can avoid occurring in the hopper arch formation, thereby avoid in feeding process, occurring the appearance that raw material interrupts situation, make extruding of raw material stable, the carrying out smoothly of the production of assurance.
Description of drawings
Accompanying drawing 1 is the schematic diagram that the hopper of prior art produces arch formation.
Accompanying drawing 2 is the cutaway view of anti-bridge formation hopper of the present utility model.
In the above accompanying drawing: 1, charging space; 2, hopper body; 3, feed opening; 4, ramp; 5, oral area; 6, fixed strip; 7, elasticity cloth bag.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: shown in accompanying drawing 2.
A kind of anti-bridge formation hopper is used for the charging of powder.Should comprise the hopper body 2 that surrounds charging space 1 by anti-bridge formation hopper, the cross section of hopper body 2 is circular.Charging space 1 has feed opening 3, and feed opening 3 is connected with the machine barrel of feeder usually.Be provided with ramp 4 in the charging space 1, ramp 4 is welded and fixed on the inwall that is connected in charging space 1, its cross section with also be circle, namely ramp 4 is sloping round platform.To the direction inclination of feed opening 3 and form the oral area 5 relative with feed opening 3, oral area 5 places are provided with fixed strip 6 to ramp 4 by the inwall in charging space 1, and in the present embodiment, fixed strip 6 adopts has certain thickness soft magnetic stripe.Oral area 5 places are fixedly installed sagging elasticity cloth bag 7 by soft magnetic stripe.Elasticity cloth bag 7 has two openings.Opening of elasticity cloth bag 7 and the oral area 5 of ramp 4 connect and are measure-alike.Another opening of elasticity cloth bag 7 and feed opening 3 are relative and apart from feed opening 3 general 150mm, and the size a of the relative opening of elasticity cloth bag 7 and feed opening 3 is greater than the size b of feed opening 3.
Above-mentioned anti-bridge formation hopper in use, elasticity cloth bag 7 is subjected to compression swelling and antagonistic force to impel material continually toward dirty, the elasticity cloth bag 7 of expansion plays the effect that buffer memory advances, thereby has avoided the hopper body 2 interior arch formations that occur.It can solve arch formation at all, makes the production quickly and orderly, need not to worry that material interrupts in the hopper.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
