Middle chartered plane of the prior art, baling machine are all adopt pre-formed bags to pack, and its technology of the package is all first material is arranged, then pass through pusher and the material arranged is pushed in prefabricated packaging bag, before pusher pushes in material entrance pre-formed bags, pre-formed bags is removed from bag storehouse, is transferred, and be opened, then under the effect of bag expanding mechanism, being opened by the bag mouth of pre-formed bags, material is pushed through bag expanding mechanism by pusher and is delivered in pre-formed bags。

There is very big problem and defect in the package packing machine of pre-formed bags packing materials of the prior art and technique, specific as follows:

1, pusher needs to push in pre-formed bags the material arranged from material arrangement position always, after material enters in pre-formed bags, pusher also needs to continue to push, the pre-formed bags wrapping material is pushed to enclosed mechanism place pre-formed bags opening is sealed, then pusher returns, which results in the stroke of pusher propelling movement material longer, pusher movement locus is longer。

2, pusher is when pushing material, owing to the stroke of pusher is longer, also results in pusher frame relatively big, thus causing that whole set equipment floor space is bigger。

3, pusher is when pushing material, owing to the stroke of pusher is longer, for packaging efficiency, generally can improve the propelling movement speed of pusher, the impulsive force between pusher and material can be caused relatively big, can cause the situation of material generation batch turning。

4, from packaging efficiency, the pre-formed bags packer of prior art is all that material and pre-formed bags are pushed to enclosed mechanism place and complete a stroke by pusher, then pusher is retracted into material arrangement position place and carries out the propelling movement of next material, in the process, the material at material arrangement position place have to wait for pusher complete that actuating length returns could be pushed, and material needs to wait at arrangement position place, cause the decline of packaging efficiency。

5, from multiple package position, between each station of pre-formed bags package packing machine of prior art, stroke is longer, and the operation at each station place is complex, if the material at pusher propelling movement material is in time pushing away station, arrange station with material to combine, material both arranged at this station place, pushed at this station place again, and for example open a bag station and both pre-formed bags is opened bag, material also enters bag at this station place, this has resulted in has needed multiple action on single station, and have to wait for just carrying out after everything is fully completed the action of next material at this station place, reduce packaging efficiency。

6, packaging effect, existing pre-formed bags package packing machine, pushed to time in packaging bag at material, material produces friction with packaging bag, it is easy to cause the damage of packaging bag, packaging in particular for lump material, the bag of pre-formed bags can be occurred to wipe by the corner angle of lump material to be hung, and material is entrance bag under the propelling movement of pusher, under the effect of pusher, material is easy to damage the bag of pre-formed bags, causes pre-formed bags bag damaged。
