Automatically packing machine moves bag mechanism
Technical field
The utility model belongs to package mechanism, relates to a kind of automatic packing machine and moves bag mechanism.
Background technology
In the packaging bag automatic production lines, needing automatic packing machine is its automatic bagging, and each bagging will extract a sack from a folded sack, move on to the assigned work zone.The way of traditional automatic packing machine is to utilize linear bearing to move on line slideway to drive the sack adsorption element to move to the assigned work zone.This shortcoming of moving bag actuating device is: on the one hand, its air ambient to work is had relatively high expectations, and dust can influence the service life of linear bearing and increase the resistance that it moves on line slideway; On the other hand, its complex structure, maintenance, cleaning inconvenience, equipment cost and maintenance cost are higher.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, reliable in action, long service life, automatic packing machine easy to maintenance, that cost is low to move bag mechanism.
Automatic packing machine of the present utility model moves bag mechanism and comprises a movable stand that suctorial level is installed, movable stand is forward and backward to be hinged with a suspension rod respectively, the upper end of suspension rod is hinged on the fixing frame, the four-bar linkage of movable stand, frame and a parallelogram of two suspension rod formations; Have one group of grip block to be clamped on the suspension rod, grip block is hinged with an end that is positioned at the driving cylinder of suspension rod one side, and the other end that drives cylinder is hinged on the fixing frame.Described grip block clip position on suspension rod can be adjusted.
The utility model is by being realized the shift motion of sack by the four-bar linkage of air cylinder driven, it is simple in structure, easy to maintenance, has guaranteed the reliability that moves, has prolonged long service life, has reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, in this mechanism, the sucker 2 that is used for adsorbing sack 7 is installed on the movable stand 1 of a level, and the rear and front end of movable stand respectively is hinged with a suspension rod 3, and the suspension rod upper end is hinged on the fixing frame 4, constitutes the four-bar linkage of a parallelogram.Gripped grip block 5 on the suspension rod 3 wherein, grip block is hinged with an end that drives cylinder 6, the other end that drives cylinder then is hinged on the fixing frame 4, what drive cylinder 6 flexiblely can drive movable stand 1 by four-bar linkage and carry out displacement, just can adjust the stroke of movable stand 1 by change the position that grip block 5 grips on suspension rod 3.
