Description
Technical field
The utility model relates to chartered plane in one, and what particularly relate to a kind of middle chartered plane pushes away bag action link gear.
Background technology
Middle chartered plane is applied very extensive in packaging field, is usually used to the packaging of the daily necessitiess such as toilet paper, paper diaper and sanitary napkin, is also used to the packaging of the food such as bread, cake and cake.
Such as, publication number is CN102649485A, publication date is that the Chinese invention patent application on August 29th, 2012 discloses a kind of plastic packer, particularly relate to a kind of for chartered plane in the packaging of the amenitiess such as sanitary napkin, paper diaper, toilet paper, it comprises the feed stream waterline, packaging bag travel line and the packaging bag sealing machine that connect successively, also comprises the transfer bar mechanism for product to be pushed to packaging bag sealing machine by feed stream waterline.In this kind, chartered plane can dock with the sanitary napkin of upper track, urine pants production facilities to set up automatic production line, enhances productivity; Packaging bag delivery system can realize multi-layer packaging, meets the demand of different size packaging; Sealing function fast speed is to packaging bag sealing, effective; Chartered plane compact conformation in this kind, can continuous working, achieve the pipelining that packaging is omnidistance, improve production efficiency, saved human cost, ensure that the unification of packaging quality.
For another example, publication number is CN102556397A, publication date is that the Chinese invention patent application on July 11st, 2012 discloses a kind of roll paper packing machine, it is characterized in that: comprise a shunting transfer unit, a charging reason material transfer unit, pack parts, a packaging bag storehouse, a carrier bar transfer unit, sealing output block, a rack unit.This invention enters into the packed products forming final listing from paper in reel, continuously uninterruptedly, and real omnidistance pipelining, real automation mechanized operation; Save human cost; Avoid manual operation and be subject to the impact that skill level is different, automated job fully can ensure the unitarity of end product quality.
And for example, notification number is CN203450449U, the day for announcing is that the Chinese utility model patent on February 26th, 2014 discloses chartered plane in a kind of food, comprise reason material parts, transfer unit, push away bag parts, open bag parts, bag storehouse parts and sealing part, described reason material parts are arranged on transfer unit side, bag parts are pushed away described in being provided with above described transfer unit end, bag parts side is pushed away described in described bag storehouse parts are positioned at, described bag parts of opening are positioned at and push away bag member mid-section, so the utility model is side-to-side movement open empty bag, the empty bag of width compared with small dimension can be adapted to, open bag success ratio and also comparatively rotate that to open the mode of bag high.It is simple that the utility model opens bag block construction, and bag openning body entirety drives by servomotor and seesaws, and open bag pawl and carry out side-to-side movement by opening a bag cylinder drive, the cooperation of both direction motion realizes opening a bag action.So the utility model is side-to-side movement open empty bag, the empty bag of width compared with small dimension can be adapted to, open bag success ratio and also comparatively rotate that to open the mode of bag high.
Above-mentioned disclosed patent is lifted action at the push rod realizing bag pulling mechanism and is all realized with cylinder, completes above-mentioned action there is following defect with cylinder:
1, air cylinder driven is steady not, and action completes not in place, and particularly under package speed faster situation, air cylinder driven often action completes not in place, causes push rod raising height to contact with connection with wrapping of piece not, causes damage and the blocking of connection with wrapping of piece; Or suction bag bar raising height is inadequate, causes packaging bag can not load desired location in time, cannot complete package handling.
2, each action needs independently cylinder, and uses cylinder more, and each cylinder needs to connect independent gas supply mechanism, and mechanism is complicated, take up room large, and the electricity needed is comparatively large, causes the waste of electricity.
3, Indivudual cylinder drives, and when rigging up and debugging, ensure the precise match of each action, workman's work capacity is huge.Because each cylinder works alone, once one of them action is not in place, just can not accurate fit with other two actions, packaging action can not be completed.Need workman again to debug, waste a large amount of work-hourses.
Utility model content
For above-mentioned deficiency of the prior art, what the utility model provided a kind of middle chartered plane pushes away bag action link gear, in the utility model, the bag action link gear cam that pushes away of chartered plane instead of cylinder, in being realized by the effect of cam, the push rod of chartered plane bag pulling mechanism lifts action, thus effectively ensure that bag pulling mechanism push rod lifts action and puts in place, allow and push away bag action and realize smoothly, allow whole production procedure go on smoothly.
