first indicator light 12 and the second indicator light 13 are For LED light, 11 model DYLY-103 of weight induction device, then one layer of latex of smearing that electronic scale 10 is uniform and a small amount of, then will Storage bag 14 is unfolded and is placed on the upper end of electronic scale 10, and the bottom end of storage bag 14 and the top of electronic scale 10 are mutually viscous at this time It connects, then fixing clamp 20 is stretched to the top end of storage bag 14 by connecting rope 19, then pin first clamping plate 2001 and the with hand The end of second splint 2002, adjustable spring 2003 is in the state shunk, and first clamping plate 2001 and second clamping plate at this time 2002 top is opened, and certain space is presented, then the outer wall of storage bag 14 is embedded in first clamping plate 2001 and second clamping plate At spatial position between 2002, and the pressing to first clamping plate 2001 and second clamping plate 2002 is unclamped, at this time adjustable spring 2003 restore to original position, and the top side of storage bag 14 can be connected firmly with fixing clamp 20, will set according still further to the above method The surrounding of object bag 14 is attached respectively with fixing clamp 20, and particle is then poured into feed pipe 21, and particle passes through charging at this time Drainage plate 22 inside pipe 21 can smoothly enter into storage bag 14, at this time the weight induction device 11 in 14 oxidising Fe scale 10 of storage bag The weight change that can sense storage bag 14 constantly, when weight induction device 11 senses set by the arrival of the weight in storage bag 14 When fixed numerical value, by information identification module and information conveyance module by the information conveyance to center under the action of power module In processing module, the working condition of second hydraulic cylinder 29 is controlled under the action of central processing module at this time, second is hydraulic at this time Cylinder 29 is started to work, and the second hydraulic stem 28 drives the first cover board 25 and the second cover board 26 slowly mobile toward opposite direction, at this time First cover board 25 and the second cover board 26 are moved backward in the inner wall of extension board 23 by the second sliding block 24, until the

the second indicator light 13 then shows red, in order to which user is in storage bag 14 The judgement of particle weight turns off 29 power switch of second hydraulic cylinder, secondly during particle enters storage bag 14, can beat The power switch for opening driving motor 9 connects because being axis connection between gear 8 and driving motor 9 between snap-gauge 7 and gear 8 for engagement It connects, gear 8 also drives snap-gauge 7 to slide up and down, and snap-gauge 7 drives movable plate 6 and passes through the first sliding block 5 in the inner wall of partition 4 at this time It slides up and down, certain memory space can be provided for storage bag 14, particle is avoided to let out during entering storage bag 14 The case where leakage, closes the power switch of driving motor 9, finally opens the first liquid after by the lifting to certain space of electronic scale 10 The power switch of cylinder pressure 15, the first hydraulic stem 16 drives the first pressure ram 17 and 18 opposite direction of the second pressure ram mobile at this time, It is bonded to each other place to the end of the outer end point of the end and the second pressure ram 18 of the outer end point of the first pressure ram 17, it can be to glove Air inside bag 14 is squeezed, and after to be extruded, closes the power switch of first hydraulic cylinder 15, at this time the first pressure ram 17 and second pressure ram 18 be back to original position, fixing clamp 20 is taken from the endpoint surrounding of storage bag 14 according still further to the above method It opens, then opens the power switch of heating wire 32, heating wire 32 can provide certain heat for heat-sealing roller 31 at this time, then by shaft 33 It is mechanically connected with a certain rotation, and the top of storage bag 14 is placed on to the outer wall of heat-sealing roller 31, it is hot under the action of heating power at this time Seal the top close adhesion of roller 31 and storage bag 14, and the gently process of rotating shaft 33 so that the top of storage bag 14 and The contact area for sealing roller 31 increases, then rotates freely pressing plate 34 by shaft 33 and be folded to, the inner wall and glove of pressing plate 34 The top of bag 14 fits closely place, can sealing development working properly to storage bag 14, to the sealing of storage bag 14 after, press Storage bag 14 is taken out from the outer wall of heat-sealing roller 31 according to aforesaid way, the encapsulation work to storage bag 14 can be completed, if desired When being cleaned to the outer wall of heat-sealing roller 31, still rotation heat-sealing roller 31, because the outer wall of the outer wall and hairbrush 36 of heat-sealing roller 31 is tight Closely connected conjunction can clean the outer wall of heat-sealing roller 31, turn off the power switch of heating wire 32, heating wire 32 stops at this time The use process for preventing leakage automatic sealing device of entire granule packaging balanced weight is completed in work like this, this is practical The novel relevant technology of circuit being related to is disclosed prior art.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its inventive concept is subject to equivalent substitution or change, should all cover the protection scope of the utility model it It is interior.
