As preferably, described contiguous block is provided with two blend stops, and described two blend stops are distributed in the both sides of described slide rail, between described two blend stops and slide rail, form two stopper slots, and two sidewalls of described chute are contained in described two stopper slots correspondingly.The suffered distortion power of slide rail in can anti-skidding process, thus slide rail flexural deformation effectively avoided.
The utility model also comprises the translation mechanism that drives described Connection Block translation.When not needing when being cut off thing (as bag rope) and make shear action, scissors translation mechanism leaves scissors and is sheared thing, can prevent that scissors from interfering the motion that is sheared thing.
As preferably, described translation mechanism comprises flat-removing air cyclinder.Good reliability when shearing, environmental protection.
As preferably, described flat-removing air cyclinder is dual piston cylinder, and two pistons of described flat-removing air cyclinder all link together with described contiguous block.Can prevent that scissors entirety from producing rotary movement, good reliability.
As preferably, the two is positioned at the same side of described contiguous block described flat-removing air cyclinder and scissors.Structural compactness is good.
As preferably, described spring housing is located on described hinge, and described spring is located in described shear blade.Mechanism's compactedness is good.
The utlity model has following advantage: automaticity is good, simple in structure, Reliability of Microprocessor is good, and the efficiency while cutting is high, while being applied to the cutting of bag rope, can reduce artificial that bag rope cuts, be convenient to production management; Shear blade is not easy to produce along the axial movement of hinge, good reliability when cutting, and shear rate is fast; Between shear blade, shear blade is with producing along hinge and also can not produce the movement axial along hinge after axial wearing and tearing between hinge.
