Description

It is pre- to take out suction type powder-bagging device

Technical field

The utility model discloses a kind of pre- pumping suction type powder-bagging devices, belong to packaging machinery field.

Background technique

Patent document CN203921221U discloses a kind of universal closed powder-bagging device, keeps away when packing powder Dust spilling is exempted from.But dust spilling asks when still there is a small amount of dust ejection in actual use, arranging sack Topic, because cannot compress sealing between handgrip and side sealing plate completely, is constantly present the gap of very little, the barrel in powder pack The inside will form positive pressure, and the dust removing tube of barrel two sides cannot in time take positive pressure air away, cause positive pressure dust laden air from seam It is sprayed in gap；Bag opening part is dust laden air after pack, this part dust also will discharge when sack is organized into "-" type Into air；In addition, being easy to be mixed into air, while positive pressure air in powder there are positive pressure inside barrel when due to powder pack Also can slow down powder falling speed, bag time is caused to extend, packing machine production capacity decline, at present pack powder can Power is in 600 bags/hour or less.

Utility model content

It is sprayed to solve a small amount of dust existing for existing closed powder-bagging device, sack dust overflows, powder Slow-footed problem is packed, the utility model proposes a kind of pre- pumping negative pressure on the basis of patent document CN203921221U Formula powder-bagging device, it includes transition hopper 1, secondary bin gate 2, negative pressure barrel 3, closed powder sackholder 4, pack handgrip 5, the lower end of the transition hopper 1 connects secondary bin gate 2, and secondary bin gate 2 is equipped with material stock cylinder 21, is equipped with below material stock cylinder 21 and cuts material Overhead door 23 cuts material overhead door 23 and is driven by overhead door cylinder 22, cuts powder when material overhead door 23 is closed and is stored in material stock cylinder 21 and Transition Materials In bucket 1, secondary 2 lower end of bin gate connects negative pressure barrel 3, and the side wall 33 of negative pressure barrel 3 is connected to exhaust tube 34, exhaust tube 34 Inlet be equipped with valve plate 32, valve plate 32 connect with the cylinder rod of valve plate cylinder 31, valve plate 32 when the cylinder rod stretching of valve plate cylinder 31 The entrance of exhaust tube 31 is left, the lower end of the negative pressure barrel 3 connects closed powder sackholder 4, closed powder sackholder 4 Two sides be equipped with pack handgrip 5.

It is closed the working principle of the utility model is: cutting material overhead door 23 when original state, batch scale launches powder A to two It is stored in secondary bin gate 2 and transition hopper 1, the cylinder rod stretching of valve plate cylinder 31 makes valve plate 32 leave the entrance of exhaust tube 31, works as sky After bag B is placed on closed powder sackholder 4, the dust removing tube of exhaust tube 31 and closed powder sackholder 4 starts to be evacuated, The inner space for cutting 23 lower section of material overhead door is set to become negative pressuren zone (region as shown in Fig. 5, Fig. 6 in circle for negative sign), simultaneously The inner space for cutting 23 top of material overhead door becomes opposite zone of positive pressure (region as shown in Fig. 5, Fig. 6 in circle for positive sign), so The entrance of material overhead door 23 opening, the closing exhaust tube 31 of valve plate 32 is cut afterwards, and powder A is through negative pressure barrel 3, closed powder sackholder 4 And be fitted into empty bag B, the dust removing tube in powder A bagging process in closed powder sackholder 4 is kept it turned on, and pack terminates After cut material overhead door 23 close, valve plate 32 open, into next working cycles.

The beneficial effects of the utility model are: two spaces up and down are divided into using secondary material goalkeeper's material dropping channel, It is preparatory that the blanking space below material overhead door will be cut using the exhaust tube of negative pressure barrel and the dust removing tube of closed powder-bagging device Taking out is negative pressure state, avoids and forms positive pressure in powder bagging process in blanking channel, so as to avoid dust ejection and powder In be mixed into air, decrease pack after the remaining dust of bag opening part, accelerate powder pack speed, make powder packaging The ability of machine can achieve 800 bags/hour；Using movable valve plate, the entrance of exhaust tube can be closed when powder falls, and prevented Only material enters in exhaust tube and influences packed weight.
