A kind of pretreatment unit for flattening before vacuum packaging bag sealing
Technical field
The present invention relates to packaging field, particularly about a kind of pretreatment unit for flattening before vacuum packaging bag sealing.
Background technology
Vacuum bag is common food packaged type, finds in actual production, if the content of pack is when vacuumizing, the placement of its content does not flatten, then vacuumize final vacuum bag meeting local projection, affect the aesthetic property of product external packaging.
Summary of the invention
In view of this, the present invention, for solving the problems of the technologies described above, provides a kind of pretreatment unit for flattening before vacuum packaging bag sealing.
Object of the present invention is achieved through the following technical solutions:
For the pretreatment unit flattened before vacuum packaging bag sealing, comprise frame, be arranged on driven cotton-padded covering in frame and initiatively cotton-padded covering, for driving the motor of initiatively cotton-padded covering, for regulating two adjusting cylinders of driven cotton-padded covering and the initiatively spacing of cotton-padded covering.
Described frame comprises two pieces and is provided with the side fixed block of corner and connects driven shaft and the imput shaft of dual-side fixed block, also pipe link is provided with between described two pieces of side fixed blocks, driven shaft and imput shaft are parallel to each other, described driven cotton-padded covering is sleeved on driven shaft rotationally, and described active cotton-padded covering is fixed in imput shaft un-rotatably; One side end of described imput shaft is provided with teeth, and described motor is connected with imput shaft by chain, and chain and teeth engage each other, and the described push rod of two adjusting cylinders is connected respectively with the both ends of driven shaft; Described two pieces of side fixed blocks are equipped with imput shaft fixed orifice and driven shaft fixes elongated hole, described imput shaft fixed orifice, driven shaft fix elongated hole and motor output end is on same straight line, described driven shaft fixes elongated hole and motor output end divides the both sides being located at imput shaft fixed orifice, imput shaft is by bearing assembling nested with imput shaft fixed orifice, and driven shaft fixes the nested assembling of elongated hole by bearing and driven shaft; The left and right sides of described imput shaft fixed orifice is provided with detouchable Fixing shrink ring.
Frame, driven cotton-padded covering, active cotton-padded covering, a motor and two adjusting cylinders form a working group, and the described pretreatment unit for flattening before vacuum packaging bag sealing comprises at least one working group.
Preferably, the quantity of described working group is more than or equal to two.
Described multiple working group is arranged in parallel.
The present invention compared to the beneficial effect of prior art is:
After vacuum bagged enters food, first flattened by the pretreatment unit work for flattening before vacuum packaging bag sealing of the present invention and process, then vacuum bag is vacuumized, can avoid vacuum bag that the serious projection of local occurs, improve the aesthetic property of product external packaging.Vacuum bag before vacuumizing inserts the pretreatment unit for flattening before vacuum packaging bag sealing of the present invention, suitable distance is in make the spacing of driven cotton-padded covering and active cotton-padded covering by adjustment adjusting cylinders, initiatively cotton-padded covering rotates constantly under the driving of motor, drive and wait that flattening vacuum bag is passed by the gap of driven cotton-padded covering and active cotton-padded covering, complete vacuum bag vacuumize before pressing work, the work efficiency of pretreatment unit of the present invention is high and relatively simply make cost lower due to structure.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any limitation of the invention.
Fig. 1 is the integral structure figure of the pretreatment unit for flattening before vacuum packaging bag sealing of the present invention.
Detailed description of the invention
The present invention to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
Please refer to Fig. 1, the embodiment of the present invention comprises:
For the pretreatment unit flattened before vacuum packaging bag sealing, comprise frame 3, be arranged on driven cotton-padded covering 1 in frame 3 and initiatively cotton-padded covering 2, for driving the motor 4 of initiatively cotton-padded covering 2, for regulating two adjusting cylinders of driven cotton-padded covering 1 and the initiatively spacing of cotton-padded covering 2.
Frame 3 comprises two pieces and is provided with the side fixed block of corner and connects driven shaft 31 and the imput shaft 32 of dual-side fixed block, also pipe link is provided with between two pieces of side fixed blocks, driven shaft 31 and imput shaft 32 are parallel to each other, driven cotton-padded covering 1 is sleeved on driven shaft 31 rotationally, and initiatively cotton-padded covering 2 is fixed in imput shaft 32 un-rotatably; One side end of imput shaft 32 is provided with teeth, and motor 4 is connected with imput shaft 32 by chain, and chain and teeth engage each other, and the push rod 51 of two adjusting cylinders is connected respectively with the both ends of driven shaft 31; Two pieces of side fixed blocks are equipped with imput shaft fixed orifice and driven shaft fixes elongated hole, imput shaft fixed orifice, driven shaft fix elongated hole and motor output end is on same straight line, driven shaft fixes elongated hole and motor output end divides the both sides being located at imput shaft fixed orifice, imput shaft is by bearing assembling nested with imput shaft fixed orifice, and driven shaft fixes the nested assembling of elongated hole by bearing and driven shaft; The left and right sides of imput shaft fixed orifice is provided with detouchable Fixing shrink ring.
A frame 3, driven cotton-padded covering 1, one initiatively cotton-padded covering 2, motor 4 and two adjusting cylinders forms a working group, comprises at least one working group for the pretreatment unit flattened before vacuum packaging bag sealing.
Preferably, the quantity of working group equals two, and this Liang Ge working group is arranged in parallel, and driven cotton-padded covering and the spacing of active cotton-padded covering of first job group are greater than the driven cotton-padded covering of second working group and the spacing of active cotton-padded covering.
After vacuum bagged enters food, first processed by flattening for the pretreatment unit work flattened before vacuum packaging bag sealing of the present embodiment, then vacuum bag is vacuumized, can avoid vacuum bag that the serious projection of local occurs, improve the aesthetic property of product external packaging.Vacuum bag before vacuumizing inserts the pretreatment unit for flattening before vacuum packaging bag sealing of the present embodiment, suitable distance is in make the spacing of driven cotton-padded covering and active cotton-padded covering by adjustment adjusting cylinders, initiatively cotton-padded covering rotates constantly under the driving of motor, drive and wait that flattening vacuum bag is passed by the gap of driven cotton-padded covering and active cotton-padded covering, complete vacuum bag vacuumize before pressing work, the work efficiency of the pretreatment unit of the present embodiment is high and relatively simply make cost lower due to structure.
Finally should be noted that; above embodiment illustrates technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
