Description
Technical field
The utility model belongs to film take-up field, is specifically related to a kind of film take-up Wrinkle-resisting unit.
Background technology
Film take-up is a kind of device that film harvest is rolled up by plastics masking industry, Lap Technology is the requisite a kind of technique of masking industry, film roll rolling poor effect is often caused after tradition winder carries out film rolling, tight inside but loose outside, very easily wrinkling, clot process is disconnected film easily, and film roll easily exists waste product film.Especially, on flexible packaging printing manufacturing line, some films, because having some build-in attribute or being difficult to the defect eliminated, easily cause it to crumple problem walking in material process to produce, and then produce defective products, cause raw material to waste in a large number.
Chinese patent literature CN 203754091U discloses a kind of Novel film winding-shrinking machine for plastics masking industry, in this device film by film guiding roller body successively be initiatively fed into roller, film yield recording device, film breadth expanding unit, web tension control apparatus, film limit inductor and lap former and be in transmission connection.Structure is comparatively complicated, adds the energy consumption in production, adds the productive costs of enterprise.In order to easy needs in actual production process, adopt more and add straight roller in wrap-up front end and tighten up to make film, reduce wrinkling problem, though there is certain effect, for flexible or that elasticity is larger film DeGrain, still have larger room for improvement.
Therefore, those skilled in the art need to provide a kind of structure simple, energy consumption and cost low, the film take-up Wrinkle-resisting unit that stable and rolling is effective.
Utility model content
For above-mentioned deficiency, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, energy consumption and cost low, the film take-up Wrinkle-resisting unit that stable and rolling is effective.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of film take-up Wrinkle-resisting unit, this Wrinkle-resisting unit is set to the bowed roller being in wrap-up upstream, and on two external parts of described bowed roller, correspondence is connected with regulating mechanism.
Preferably, described regulating mechanism comprises the draw-in groove unit and hexagonal double-ended bolt unit that form snap fit.
Further, described draw-in groove unit comprises draw-in groove, and is installed in adjust bar draw-in groove bottom surface being convenient to rotate draw-in groove; Described hexagonal double-ended bolt unit is made up of the hexagonal screw rod be connected as a single entity and hexagonal (hexagon)nut, and described hexagonal (hexagon)nut is located at the one end near draw-in groove, and the smooth surface of described hexagonal (hexagon)nut.
Further, described draw-in groove realizes the engaging with the straight hex surface of hexagonal (hexagon)nut by the fastener that two side is installed; The equal fixed cover of two external parts of described bowed roller is located at the inside of hexagonal double-ended bolt unit.
Further, described fastener is made up of the screw of interworking and nut, and described nut and screw-driving make draw-in groove and hexagonal (hexagon)nut fixing and locking.
Preferably, the sinuousness of described bowed roller is in the scope of 5 ~ 15mm
The beneficial effects of the utility model are:
1), the utility model arranges bowed roller in wrap-up upstream, two external parts of bowed roller fix sheathed hexagonal double-ended bolt unit, and draw-in groove realizes the engaging with the straight hex surface of hexagonal (hexagon)nut by mounting fastener on two side, in process of production, can according to the differential tension of different film or other character, first loosening fasteners slightly, adjust bar can along the vertical direction activity of two fastener lines, according to the clamped position of the character determination draw-in groove of film and the straight hex surface of hexagonal (hexagon)nut, then fixation fastener, the position of corresponding bowed roller there occurs change, also the space displacement namely and between wrap-up changes, and by conversion draw-in groove and the different snap-latch surfaces between hexagonal (hexagon)nut, the direction of replaceable arc, what make film walks to expect that direction and bowed roller protrusion direction keep basically identical.
This device can make debugging pointedly to the film product of different size, different attribute, without the need to changing the bowed roller of different curvature, improves the practicality of this device, for enterprise creates larger productive value.
2), in the utility model bowed roller rubber coating go for a stroll axle rotate time, roll surface leans on ectocentral two side portions to produce the drafting force to both sides to centre portion, thus film is flattened, while this Wrinkle-resisting unit of guarantee is in conjunction with wrap-up smooth operation, reach good wrinkle-proof effect.And the sinuousness of bowed roller is in the scope of 5 ~ 15mm, ensure that this effect, radian too great Yi causes the winding of film, the flattening effect that too little then out of reach is enough.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, legend is a kind of film take-up Wrinkle-resisting unit, and this Wrinkle-resisting unit is set to the bowed roller 2 being in wrap-up 1 upstream.
As shown in Figure 2,3, on two external parts 20 of bowed roller 2, correspondence is provided with regulating mechanism 3.Regulating mechanism 3 comprises the draw-in groove unit and hexagonal double-ended bolt unit that form snap fit.Wherein, draw-in groove unit comprises draw-in groove 31, and is installed in the adjust bar 33 draw-in groove 31 bottom surface being convenient to rotate draw-in groove 31; Hexagonal double-ended bolt unit is made up of with hexagonal (hexagon)nut 34 hexagonal screw rod 30 be connected as a single entity, and described hexagonal (hexagon)nut 34 is located at the one end near draw-in groove 31, and the smooth surface of described hexagonal (hexagon)nut 34.
Draw-in groove 31 realizes the engaging with the straight hex surface of hexagonal (hexagon)nut 34 by the fastener 32 that two side is installed; The equal fixed cover of two external parts 20 of bowed roller 2 is located at the inside of hexagonal double-ended bolt unit.
Fastener 32 is made up of the screw of interworking and nut, and nut and screw-driving make draw-in groove 31 and hexagonal (hexagon)nut 34 fixing and locking.
Bowed roller 2, by bending shaft camber, axle is equipped with bearing mutually across a certain distance, bearing overlaps and becomes with rubber coating the roller that has arc, rubber coating can pivot, and the sinuousness of bowed roller is in the scope of 5 ~ 15mm.
Below in conjunction with accompanying drawing, working process of the present utility model is described further.
When replacing different size, when the film of different attribute carries out rolling, first loosening fasteners 32 slightly, adjust bar 33 can be movable in the vertical plane surface of two fastener 32 lines, also namely movable along the filled arrows direction do not made marks shown in Fig. 2, change the clamped position of the straight hex surface of draw-in groove 31 and hexagonal (hexagon)nut 34, the position of corresponding bowed roller 2 also there occurs change, also the space displacement namely and between wrap-up 1 changes, then fixation fastener 32, thus achieve for without the adjustment of film to bowed roller 2 locus, the application force of adjustment bowed roller 2 pairs of films.
Then, by the snap-latch surface between conversion draw-in groove 31 and hexagonal (hexagon)nut 30, change the protrusion direction of arc, what make film walks to expect that the protrusion direction of direction and bowed roller 2 is basically identical, the rubber coating curved surface of bowed roller 2 constantly rotates, and drives film constantly to walk material, and bowed roller 2 roll surface leans on ectocentral two side portions to produce the drafting force to both sides to centre portion, thus film is flattened, reach good wrinkle-proof effect.
