(2) background technology
Along with the raising of every profession and trade capacity rating, market quick and various, industries such as petrochemical complex, medicine, food, building materials, grain are had higher requirement to the post-processing packing: require the capacity packing of post-processing packing to want high.For example chemical industry has proposed the requirement of 1600 bags/hour (25 kilograms/bag) to the packing of particulate material; The availability height of equipment.The availability of fitness for purpose equipment is not less than 95%; Comformability to material is eager to excel.To the same a kind of material or the different material of different bulk densities, equipment does not adjust or only does simple adjustment and can pack.
Wrapping machine is distinguished by degree of automation and can be divided into following two classes at present:
One class is that the semi-automatic packer group is the drain hole place that manually ready made packaging bag is clamped in unit, and unit is finished filling, sealing packaging processs such as (needing artificial assistance) then.The advantage of semi-automatic packer group is simple, reliable, and is less demanding to maintenance, repair; But semi-automatic packer group productive capacity not high (800 bag/hour about), working strength of workers is big, and to materials such as powders, workman's operating conditions is abominable.
Another kind of is the automatic packaging machine group
The automatic packaging machine group is appointment place that manually ready made packaging bag is placed on request the packing unit, packs unit then and finishes bag taking automatically, goes up bag, opens packaging processs such as bag, filling, opening shaping, sealing.The automatic packaging machine group mainly contains following several form at present: first kind is swing arm type automatic packaging machine group.This kind packing unit is to increase automatic bag taking, bag-loading mechanism on semi-automatic packer group basis, the artificial clamping pocket of semi-automatic packer group is changed by pneumatic swing arm leverage finish.Unit mainly is made up of bag supply machine, bag openning body, bag-loading mechanism, sackholder, sewing machine, upright bag conveyer etc.This kind packing unit has reduced working strength of workers, the productive capacity maximum can reach 1000 bags/hour, can be used as the semi-automatic packer group in case of necessity and use; But the bag-loading mechanism of swing arm type automatic packaging machine group is complicated, and the leverage in the bag-loading mechanism is adjusted complicated, and adjustment requires high, and the fault rate of whole unit is higher; Second kind is the horizontal formula automatic packaging machine group of advancing.This kind packing unit increases than swing arm type automatic packaging machine group degree of automation, and unit mainly is made up of bag supply machine, bag packer (include bin gate mechanism, reducing mechanism, horizontal enter mechanism etc.), a folder mouthful dent puller, sewing machine, upright bag conveyer etc.After the pocket filling, pocket is entered mechanism and delivers to opening shaping mechanism and carry out opening shaping by horizontal, and the pocket behind the opening shaping is sealing again, has improved the sealing quality like this.The productive capacity of this kind packing unit depends mainly on the horizontal moving velocity that enters mechanism, at present horizontal driving of entering mechanism mainly contains dual mode: air cylinder driven and driven by servomotor, horizontal nearly mechanism by the packing unit productive capacity maximum of air cylinder driven can reach 1000 bags/hour, horizontal advance mechanism by the packing unit productive capacity maximum of driven by servomotor can reach 1200 bags/hour.This kind packing unit has higher requirements to the quality of empty pocket and the dimensional uniformity of empty pocket, be subjected to bag supply machine version and supply a bag mode to limit, empty pocket will supplied on the bag dish by certain requirement pendulum continually, a lot of actions of unit are finished by vacuum in addition, some vacuum line still moves, reveal or the decline of vacuum source degree of vacuum as long as there is place's pipeline to have like this, unit work is just unreliable, even whole unit can't be worked.
Above-mentioned various packing unit respectively has certain comformability, but their common shortcomings are: must produce certain mass in advance and the packaging bag of unified specification is arranged; Packing unit when work, must be constantly by artificial supply packaging bag, and also the packaging bag of supplying with must be put by the requirement of unit; The productive capacity of above-mentioned packing unit is not very high, particulate material full output 1200 bags/hour.
(3) summary of the invention
The object of the present invention is to provide a kind of compact conformation, operating efficiency height, the bag forming automatic packaging machine of suitable packed powder, pellet.
