Description
Technical field
The present invention relates to packing technique field, relate to a kind of film bag mouth opener in particular, it can be applied in the automatic packaging process of such as paper handkerchief, for automatically strutting film, being beneficial to lower step operation and can being loaded by paper handkerchief easily in the inner chamber of film formation.
Background technology
For products such as paper handkerchiefs, it is generally all into underwriting and sells, and namely also includes packing film in the periphery of paper handkerchief.The packaging of this paper handkerchief is generally all realized by automated packaging equipment, its packaging step generally: utilize sucker from the bag film locker room position automatic sucking bag film that processing and fabricating is good in advance, this bag film is flats; Then utilize film bag mouth opener to be opened by the opening of this bag film, paper handkerchief is delivered in the bag film strutted by recycling load transfer device, finally seals bag film again and completes the packaging of one bag of paper handkerchief.
At present, when strutting action to bag film, existing film bag mouth opener generally all needs to process a sliding shoe, as shown in Figure 1, this sliding shoe 200 has the first horizontal rail 210, second horizontal rail 220 and play the oblique orbit 230 of transitional function between the first horizontal rail 210 and the second horizontal rail 220, diff-H is there is between this first horizontal rail 210 and second horizontal rail 220, so utilize this diff-H to realize opening and folding of two braces in film bag mouth opener, this diff-H is then for film bag mouth opener can strut the distance of film.
It can thus be appreciated that at least there is following defect in above-mentioned traditional film bag mouth opener:
One, because the distance in this sliding shoe between the first horizontal rail 210 and the second horizontal rail 220 is a fixed value, in order to fully packing film can be supported, the sliding shoe of a kind of specification like this can only be used for carrying out support bag to a kind of packing film of specification, therefore often need the sliding shoe processing plurality of specifications, not only cost is higher, and adds work capacity to material storage;
Two, when board needs change packing of product specification, when namely needing adjustment openings of sizes, then need shut down and change sliding shoe, so there is ineffective defect;
Three, above-mentioned sliding shoe 200 needs to process the first horizontal rail 210, second horizontal rail 220 and oblique orbit 230, and its difficulty of processing is comparatively large, and track is easy to wear, and the gap that this sliding shoe coordinates with slide mechanism is large, and can have influence on the accuracy of folding.
For the problems referred to above, the present inventor, through concentrating on studies, have developed this case.
Summary of the invention
The object of the present invention is to provide a kind of film bag mouth opener, to solve film bag mouth opener in prior art, there is the problem that openings of sizes changeability is poor and sliding shoe difficulty of processing is large and can affect folding accuracy.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of film bag mouth opener, wherein, comprise motor, trace, sliding shoe, line slide rail, slide mechanism, first rotating shaft and the first swing arm, the output shaft of this motor is fixedly installed the transfer block of rotating with output shaft synchronous, this trace one end is articulated in transfer block, the other end is articulated on sliding shoe, the attachment point of the pivoting point of this trace and transfer block and transfer block and motor output shaft is staggered, this sliding shoe can linearly slide rail and sliding in a first direction, this sliding shoe is provided with the rectilinear orbit extended along second direction, this slide mechanism one end is slidably arranged in rectilinear orbit, the other end is fixed in the first rotating shaft, this first swing arm and the first rotating shaft are fixedly linked.
Described film bag mouth opener also comprises the second rotating shaft and connecting rod mechanism, and this second swing arm is fixed in the second rotating shaft, and this connecting rod mechanism is arranged on and makes the rotation of the first rotating shaft can back transfer to the second rotating shaft between the first rotating shaft and the second rotating shaft.
Described connecting rod mechanism comprises first connecting rod, second connecting rod and third connecting rod, this first connecting rod one end is fixed in the first rotating shaft, the first connecting rod other end is articulated in one end of second connecting rod, the other end of this second connecting rod and one end pivot joint of third connecting rod, the other end of this third connecting rod is fixed in the second rotating shaft.
Described film bag mouth opener also comprises fixed mount, and this first rotating shaft and the second rotating shaft are positioned on fixed mount all rotationally, and this motor is fixed on fixed mount.
Described first direction is vertical direction, and this second direction is horizontal direction.
Described motor adopts servomotor, is also provided with servo deceleration machine between this servomotor and transfer block.
After adopting said structure, a kind of film bag mouth opener that the present invention relates to, under the drive of motor, this transfer block can with motor output shaft synchronous axial system, so make trace can drive sliding shoe linearly slide rail slide in a first direction, now because this slide mechanism one end is slidably arranged in the rectilinear orbit of sliding shoe, so one end of this slide mechanism also will produce displacement in a first direction, again because the other end of this slide mechanism is fixed in the first rotating shaft, so this slide mechanism is by drive first axis of rotation, and resulting belt moves swing arm motion.
Compared with prior art, the present invention at least has following beneficial effect:
One, in a structure of the in-vention, for the motion amplitude of this swing arm, first it depend on the rotational angle of the first rotating shaft, and the rotational angle of this first rotating shaft is decided by sliding shoe sliding distance in a first direction, this sliding distance is decided by the rotational angle of motor output shaft again, so when needing the openings of sizes changing film, the end position changing electric machine rotation angle is only needed to realize easily, and without the need to changing sliding shoe as in the prior art, substantially increase work efficiency;
Two, because the sliding shoe in the present invention only has a rectilinear orbit, processing and manufacturing difficulty like this is low, and accuracy rate is high, thus has the high feature of folding accuracy.
