Abstract
The utility model discloses a kind of powder screw filling machine.This powder screw filling machine, comprises hopper, is provided with body, in body, is provided with screw rod in the bottom of hopper, and screw rod is provided with the engine installation driving it to rotate, and the upper side of body is provided with deflation hole, is provided with filter screen at deflation hole.Can pressing materials when material in hopper is carried downwards by screw rod, air extrusion in material is gone out some, air is discharged, because air can be discharged smoothly by the deflation hole of body upper side, make material can follow screw rod smoothly to extrude downwards and enter packaging bag, avoid putty.
Description
Technical field
The utility model relates to the screw filling equipment in package packing machine field, especially relates to a kind of powder screw filling machine.
Background technology
Screw filling machine, adopts metering filling, because precision is high, speed is widely used in powder class filling and packing field soon.But for most powder (as agricultural chemicals, feed pre-mixing material etc.), the bulk density step-down of material after the techniques such as mixing, stirring, in material gap, air content increases.It is large that traditional powder screw filling machine causes material bagging to take volume, and the pouch-type problem such as unsightly, even if the later stage increases shaping exhaust on wrapping machine, also only can make material together extrude together with air, still be difficult to process.Because the problem of putty also easily appears in the increase of material air content.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, and providing a kind of suitably can discharge the air in material, increases solid accumulation density, avoids the powder screw filling machine of putty.
For achieving the above object, the technical scheme that the utility model powder screw filling machine adopts is:
A kind of powder screw filling machine, comprises hopper, is provided with body, in body, is provided with screw rod in the bottom of hopper, and screw rod is provided with the engine installation driving it to rotate, and the upper side of body is provided with deflation hole, is provided with filter screen at deflation hole.Can pressing materials when material in hopper is carried downwards by screw rod, air extrusion in material is gone out some, air is discharged by the deflation hole of body upper side, because air can be discharged smoothly, makes material can follow screw rod smoothly and extrudes downwards and enter packaging bag.
Described screw rod is the screw rod of pitches, and the upside pitch of screw rod is large, and the pitch of downside is little, and deflation hole is arranged on pitch variation place.Air can better be discharged by pressing materials by the screw rod of pitches, and material is more tangible by what press, and the material maximum place that is squeezed is at pitch variation place, and deflation hole is arranged on the air that pitches place can will squeeze out more smoothly and discharges.
Body is split type, comprises upper tube body and lower tube body, is connected between upper tube body with lower tube body by filter screen, and be socketed with the gas-tpe fitting be connected with upper tube body and lower tube body respectively in the outside of filter screen look, gas-tpe fitting is provided with deflation hole.Adopt this structure to be convenient to install production, filter net jam or damage are convenient to change.
Leave gap between the inwall of gas-tpe fitting and filter screen and form negative pressure cavity.The negative pressure cavity of tool between filter screen and gas-tpe fitting, the air that express material is gone out can discharge from this cavity.
Described deflation hole is connected with negative pressure source of the gas.Negative pressure source of the gas auxiliary exhaust ports is vented, and air in material is more easily discharged.
The top of screw rod is provided with the auxiliary screw blade identical with the hand of spiral of screw rod, and the material in hopper is allocated to screw rod in the outside of screw rod by being nested with of this auxiliary screw blade.
The utility model compared with prior art, has the following advantages:
With screw to convey materials, air is extruded from deflation hole by pressing materials, and while compacting material, avoid the generation of putty phenomenon, filter screen avoids material and extrudes from deflation hole; Internal batch air reduces, and take up room after being filled into bag little, pouch-type is bulging not, very attractive in appearance; Adopt the screw rod of pitches, it is more tangible from top to bottom to be obtained by express material, improves the density of material, the extruding that the material at pitch variation place is subject to is larger, and the air herein squeezed out is maximum, arranges deflation hole herein and can ensure not putty, convey materials is rapid, and it is more accurate to measure; Gap between filter screen and gas-tpe fitting can form cavity, and when pressing materials, this cavity can cushion the material of extruding, is discharged by air smoothly, compacting material; Negative pressure source of the gas is connected with deflation hole, makes cavity become negative pressure cavity, coordinates with screw rod, is better discharged by the air in material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As depicted in figs. 1 and 2, a kind of powder screw filling machine, comprise hopper 1, hopper is bevel casing, be provided with the body 2 for discharge in the bottom of hopper, be provided with in body 2 for extruding the screw rod 3 pushing material, the pitch of the upper end of screw rod is large, the pitch of lower end is little, and the junction that pitch is large and pitch is little is pitch variation place 31.Body is split type body, comprise upper tube body 21 and lower tube body 22, connected by filter screen 4 between upper and lower body, filter screen is arranged on the outside at screw rod pitch variation place 31, the gas-tpe fitting 5 be connected with upper and lower body is socketed with in the outside of filter screen, gas-tpe fitting comprises the outside columniform housing 51 be connected with upper and lower body and the deflation hole 52 be opened on housing that are enclosed in filter screen, gas-tpe fitting is provided with deflation hole 51, between inner walls and filter screen, leave the negative pressure cavity 6 that gap is formed, deflation hole is connected with negative pressure source of the gas.The upside of hopper is provided with cover plate 11, and cover plate 11 is provided with the engine installation 7 be connected with screw rod.Be provided with the auxiliary screw blade 8 identical with the hand of spiral of screw rod at the top of screw rod, the material in hopper is allocated to screw rod in the outside of screw rod by being nested with of this auxiliary screw blade.
Engine installation drives screw rod and auxiliary blade to rotate, material in hopper is gathered to screw rod, material is discharged downwards to along body under the effect of screw rod, it is more that air in material can be extruded by the screw rod of pitches, the deflation hole at pitches place is connected with negative pressure source of the gas, negative pressure is produced in negative pressure cavity, siphon away the air in auxiliary material, supplies are vented, and further increase the density of material, it also avoid the generation of putty phenomenon, because internal batch air reduces, take up room after being filled into bag little, pouch-type is bulging not, very attractive in appearance.
