Abstract

The utility model provides a kind of film splitter, comprise frame, frame is provided with unwinding device, cutting device and wrap-up, unwinding device comprises let off roll, wrap-up comprises the wind-up roll for rolling film, and wrap-up also comprises the adjustable bow curved roll dividing the monofilm cut through to walk around from cutting device for confession be located on front side of wind-up roll.Due to adjustable bow curved roll when rotating with the wider width of common cylindrical roller contact membrane when width is the same and outer peripheral face is larger apart from the distance in axle center, so just the cornerite of single thin film on adjustable bow curved roll can be increased, tensioning also flattens film, wind-up roll like this on rear side of adjustable bow curved roll would not produce buckling phenomena in rolling through the single thin film of adjustable bow curved roll, and rolling effect is better.

Description

A kind of film splitter

Technical field

the utility model relates to membrane production equipment, particularly relates to a kind of film splitter.

Background technology

In the production process of high barrier food package film, film dividing is the very important operation of a step.The equipment that film dividing generally adopts is cutting machine, existing cutting machine generally comprises frame, the unwinding device be located in frame, cutting device and wrap-up, the duplicature made from inflation film manufacturing machine launches from unwinding device, respectively the both sides of the Width of duplicature cut away by cutting device and duplicature is rolled onto on different windings up roller respectively, thus completing and cut.Existing cutting machine often there will be in wrapup procedure film do not have tensioning and rolling time there is the phenomenon of fold, this fold can be more and more serious along with increasing of film roll, all can impact the storage of film and placing.

Utility model content

The purpose of this utility model be to provide a kind of can by film tensioning when rolling, the good cutting machine of rolling effect.

Film splitter of the present utility model adopts following technical scheme: a kind of film splitter, comprise frame, described frame is provided with unwinding device, cutting device and wrap-up, described unwinding device comprises let off roll, described wrap-up comprises the wind-up roll for rolling film, and described wrap-up also comprises the adjustable bow curved roll dividing the monofilm cut through to walk around from cutting device for confession be located on front side of wind-up roll.

Described unwinding device comprise cut off the burr of two sections of film coupling ends when being connected with follow-up film after the thin-film unreeling on let off roll is complete connect film device, described connect film device comprise for take put film coupling end take the face of putting, described in take the face of putting be provided with bearing of trend and let off roll axis being parallel, for for and the thin film cutter of its adaptation to lead the guiding grooving of bearing fit.

Described guiding grooving is along being hinged in frame with the axis of let off roll axis being parallel.

What described guiding grooving was hinged on let off roll unreels side, direction.

Adjustable bow curved roll is provided with on front side of the wind-up roll of the wrap-up of film splitter of the present utility model, rolled by wind-up roll after the single thin film pile warp adjustable bow curved roll that cutting device has been cut, due to adjustable bow curved roll when rotating with the wider width of common cylindrical roller contact membrane when width is the same and outer peripheral face is larger apart from the distance in axle center, so just the cornerite of single thin film on adjustable bow curved roll can be increased, tensioning also flattens film, wind-up roll like this on rear side of adjustable bow curved roll would not produce buckling phenomena in rolling through the single thin film of adjustable bow curved roll, rolling effect is better.

Detailed description of the invention

The embodiment of a kind of cutting machine of the present utility model: as shown in Figure 1, comprise frame 100, in frame, side is provided with unwinding device from right to left, cutting device A and wrap-up B, C, wrap-up B, C is respectively used to two parts single thin film that rolling bilayer film 100 is cut open, unwinding device, the axis of the roller that all films 10 that cutting device and wrap-up comprise are walked around extends all along the longitudinal direction, the transmission direction of film is for transmit from right to left, unwinding device comprises let off roll 1, cutting device comprises multiple roller for cutting, structure is identical with the cutting machine structure of prior art herein, repeat no more herein, wrap-up B, C comprises the wind-up roll 51 being positioned at high order end respectively, 52, wherein, also at wrap-up B in frame, the wind-up roll 51 of C, the right side of 52 is respectively equipped with adjustable bow curved roll 41, 42, the double-layer films separated by cutting device pile warp two adjustable bow curved rolls being rolled by wind-up roll corresponding on rear side of adjustable bow curved roll respectively, because adjustable bow curved roll is bending in the axial direction, film has larger cornerite when pile warp adjustable bow curved roll, can be flattened by adjustable bow curved roll stretching, when being rolled by wind-up roll, rolling effect is better, fold can not be there is in wrapup procedure, simultaneously, the curvature of adjustment adjustable bow curved roll can regulate the tensioning degree to film, better adaptability.

The left side being positioned at the let off roll 1 of the unwinding device of the frame rightmost side is also provided with and connects film device, connect film device and be mainly used in the complete rear irregular burr needing to cut off when connecting the film on next winding up roller two sections of film coupling ends of thin-film unreeling on let off roll, to enable, two roller films are concordant to be docked, connect film device and mainly comprise guiding grooving 2, the structure of guiding grooving 2 is as Fig. 2, shown in 3, comprise grooving body and the guide groove 21 being opened in grooving body upper surface, the upper surface of grooving body be for take put two sections of films take the face of putting, the length direction of guiding grooving 2 extend along front and back and with the axis being parallel of let off roll, guiding grooving to be articulated with in frame and to be positioned at let off roll and unreels side, direction, and can rotate around the axis with let off roll axis being parallel, frame is also provided with for carrying out spacing position limiting structure to the upset of guiding grooving, this position limiting structure is the L-type baffle plate with horizontal sides and vertical edge, unreel in process at let off roll, guiding grooving is turned to level attitude and by the horizontal sides block of L-type baffle plate, can not interfere with unreeling process, when let off roll has unreeled and needed to connect film, guiding grooving is turn to vertical position and fits with the vertical edge of L-type baffle plate, then film is cut by film sitting blade along guiding grooving, the butt joint edge cut out is more neat, conveniently connect film.

In the present embodiment, the unwinding device of film splitter comprise establish with let off roll side connect film device, facilitating the concordant docking of two sections of films by connecing film device, in other embodiments, can not arrange and connect film device and by manually directly cutting film and dock.

In the present embodiment, guiding grooving is hinged in frame, can turn to level attitude and does not interfere with unreeling to produce unreeling in process, in other embodiments, by guiding grooving separable joint in frame, can install when needs use, do not need to be removed when using.

In the present embodiment, what guiding grooving was hinged on let off roll unreels side, direction, more convenient when connecing film, and in other embodiments, guiding grooving can be located at other positions in frame, and the present embodiment is only to provide a kind of preferred version.

Cutting machine of the present utility model rolling effect is in use better, and frame is provided with and connects film device, more convenient when connecing film, accurately can realize the docking of two volume films, improve and cut quality.
