Background technology
At present, for domestic pillow type packing machine dog-ear device there are mainly three types of form, one kind is that cylinder drives dog-ear device, the
Two kinds are air blowing dog-ear devices, the third is that cam directly pushes away spring return function dog-ear device, and three of the above dog-ear mode is in packaging speed
Degree is than during long time running, the noise that dog-ear generates is bigger and bearing is easily damaged in faster production environment, equipment fortune
Row is extremely unstable, influences production efficiency, improves production cost.
The content of the invention
The purpose of this utility model is to provide a kind of dog-ear device, realizes packaging film dog-ear, makes after wrapper packaged more
It is smooth, beautiful, mechanical breakdown and mechanicalness noise are reduced, improves the qualification rate of packaging product.
The technical solution of the utility model is:A kind of device for implementing bag film dog-ear method described in claim 1, it is special
Sign is, including sealing axis, spatial spatial cylindrical cam and turning mechanism, two sealing axis are rotated upwardly and downwardly and are supported in rack, upper
Installation two spaces cylindrical cam in interval on the sealing axis in face, intermeshing driving is equipped in the same end of each sealing axis
Gear;The turning mechanism includes symmetrically being separately positioned on stent, side plate, swing arm, the needle roller beside two spaces cylindrical cam
Bearing, sliding block, cushion block, riser and fixed plate and guide shaft, stent are located at the top of spatial spatial cylindrical cam and are fixed in rack;Institute
The top for stating side plate is fixed on stent, and by bearing and the upper articulation of swing arm, which sets the Basolateral of side plate
There is follower lever and slide and extend into the cylinder groove of spatial spatial cylindrical cam, the lower outside of the swing arm passes through needle bearing and cunning
The inner end connection of block drives the bearing in swing arm to swing by the projection portion of spatial spatial cylindrical cam;The both ends of two guide shafts point
It is not fixed in the fixed plate of both sides, by guide shaft, fixed plate corresponding with both sides connects respectively for the opposite one side of two sliding blocks
It connects, fixed plate is connected with riser;Two sliding blocks are slidably mounted on guide shaft;The both ends of the dog-ear plate are separately fixed at two
On sliding block;The sealer is made of opposite two parts, respectively symmetrically is connected on the sealing axis described in two.
The cylinder groove of the spatial spatial cylindrical cam is equipped with bending round and smooth at one.
The spatial spatial cylindrical cam is made of two axisymmetric half portions, and is passed through screw and be mutually fastened on sealing axis
On.
The riser is connected by cushion block with rack.
The beneficial effects of the utility model are:By sealing axis spatial spatial cylindrical cam is driven to rotate, spatial spatial cylindrical cam band
Dynamic dog-ear plate does straight line disengaging movement and realizes dog-ear to packaging film, and simple in structure, compact, low noise, the application of this device can be real
Now to the dog-ear of packaging film, make wrapper packaged more smooth, beautiful, improve the qualification rate of packaging product, reduce production
Cost.

Specific embodiment
Referring to Fig. 1, a kind of bag of film dog-ear device of the utility model, including sealing axis 1, spatial spatial cylindrical cam 2 and angle folding machine
Structure, two sealing axis 1 are rotated upwardly and downwardly and are supported in rack, the interval installation two spaces cylindrical cam on sealing axis 1 above
2, intermeshing drive gear is housed in the same end of each sealing axis 1;The turning mechanism includes symmetrically setting respectively
In the stent 3 on 2 side of two spaces cylindrical cam, side plate 4, swing arm 5, needle bearing 6, sliding block 7, cushion block 8, riser 9 and fix
Plate 10 and guide shaft 11, stent 3 are located at the top of spatial spatial cylindrical cam 2 and are fixed in rack;The top of the side plate 4 is fixed on
On stent 3, by bearing 14 and the upper articulation of swing arm 5, the follower lever 15 at 5 middle part of swing arm slides the Basolateral of side plate 4
It extend into the convex groove 21 of spatial spatial cylindrical cam 2, the lower outside of the swing arm 5 passes through the inner end of needle bearing 6 and sliding block 7
Connection drives the follower lever 15 in swing arm 5 to swing by the projection portion of spatial spatial cylindrical cam 2(I.e. along sealing axis 1
Axial reciprocating is swung);The both ends of two guide shafts 11 are separately fixed in the fixed plate 10 of both sides, two sliding blocks 7 it is opposite
By guide shaft 11, fixed plate 10 corresponding with both sides connects respectively for one side, and fixed plate 10 is connected with riser 9, which passes through pad
Block 8 is connected with rack.Two sliding blocks 7 are slidably mounted on guide shaft 11;The both ends of the dog-ear plate 12 are separately fixed at two
On sliding block 7;The sealer 13 is made of opposite two parts, respectively symmetrically is connected on the sealing axis 1 described in two.Folding
Gusset 12 is conventional structure.
Referring to Fig. 2, the convex groove 21 of spatial spatial cylindrical cam 2 of the invention is equipped with round and smooth bending 22, for band movable pendulum
Follower lever 15 on arm 5 swings.The spatial spatial cylindrical cam 2 of the embodiment is by the both ends of two half-unit with two screws 23
It is mutually fastened on sealing axis 1.
The course of work of the present invention is:
(1)The drive rotation of spatial spatial cylindrical cam 2 of axis 1 is sealed when packing machine is run and is done and is rotated(Articulated shaft)Movement;
(2)The rotation of spatial spatial cylindrical cam 2 drives swing arm 5 to swing around bearing 14;
(3)Swing arm 5 is moved in a straight line by needle bearing 6 with movable slider 7 along guide shaft 11;
(4)Dog-ear plate 12 on sliding block 7 realizes the dog-ear to packaging film by the linear motion of sliding block 7;
(5)Packaging film after dog-ear is realized by sealer 13 seals packaging film, completes the dog-ear smooth to packaging film.
