Abstract
The utility model relates to a film feed roll on an automatic slitting machine, which is characterized in that ditch grooves are evenly distributed on the film feed roll, the breadths of the ditch grooves are between 0.05mm and 10mm, and the depths are from 0.02mm to 10mm. The ditch grooves can have various shapes, such as rectangular, triangular, trapezoidal and circular arc shapes, a length-measuring withdrawal roll adopts a ditch groove shape structure and has the functions that the vacuum absorption on surfaces of the film and the film feed roll is eliminated and the film is prevented from sticking to the surface of the film feed roll, so the film feed roll has advantages of smooth slitting process and accurate and stable size, and is suitable for various film materials, such as the slitting operations of mono-films and composite films.
Description
Technical field
The utility model relates to the long film feeding roller of groove structure meter on a kind of automatic guillotine.
Technical background
Traditional film feeding roller adopts no groove structure, film feeding roller material adopts rubber, when film feeding cuts operation, because roller smooth surface, easily produce vacuum suction for film class flexible material, especially elasticity strengthens after the moisture absorption such as PVA plastic sheeting, the material that surface adhesion force is strong, and its vacuum adsorption phenomenon is more outstanding.After producing vacuum suction, gently then cause film feeding charging size instability, the torn size accuracy rate is poor, and when serious, film can adhere to film feeding roller surface, makes to cut operation and can't carry out.Especially for the PVA water-soluble film, this film is along with the increase of air humidity, and aqueous ingredients increases, and thin flexible film strengthens, and adsorption affinity also increases.Therefore, limited the range of use of automatic guillotine widely.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide that a kind of simple in structure, working stability, vacuum adsorption force are little, the measuring accuracy long film feeding roller of groove structure meter used of guillotine automatically accurately.In that uniform groove is set on the film feeding roller is the surface vacuum absorption that is used for eliminating between long film feeding roller of meter and the membraneous material, to reach the long and stable purpose that cuts operation.
The technical solution of the utility model is on the long film feeding roller of traditional meter the well-distributed groove to be set, and it is characterized in that: film feeding roller surface is provided with uniform groove; The ditch groove width of counting on the long film feeding roller is 0.05mm-10mm, is 0.02mm-10mm deeply.The lip-deep groove shape of the long film feeding roller of groove structure meter is triangle or circular arc or trapezoidal or rectangle etc.
The beneficial effects of the utility model are to adopt the film feeding of groove structure, its role is to eliminate the vacuum suction on film and film feeding roller surface, prevent that adhesion of film is on the film feeding surface, make cut-parts technology steady, size is precise and stable, be applicable to various membraneous materials, as the cut-parts operation of monofilm, complex film.

Fig. 1 is a structural representation of the present utility model;
Fig. 1 a is a cross section structure scheme drawing of the present utility model;
Fig. 2 makes principle master TV structure scheme drawing for cutting sheet 2 automatically;
Fig. 3 looks structural scheme of mechanism for cutting sheet 2 automatically as a left side;
Among the figure: 1-rolling film, 2-counts long film feeding roller, 3-film feeding driven roller, 4-cutting knife, 5-finished product sheet film.
The specific embodiment
Referring to Fig. 1 and Fig. 2, slitting machine is general automatically adopts one group of film feeding roller (rubber rollers, a steel rider) and counts long operation, and steel rider is the long driven roller of feeding meter, and rubber rollers is auxilliary roller.The rolling film enters the long film feeding roller group of meter through deflector roll, be fed to the portion of cutting by the long film feeding roller group stepper drive of meter, cutting knife cuts on request synchronously, be the every feeding of film feeding roller group once, cutting knife cuts once, cutoff length is by film feeding roller group feeding control (see figure 2), this film feeding roller is parts on the automatic slitting machine, be that technical characterictic of the present utility model is on film feeding roller surface uniform groove (see figure 1) to be set, its function is to eliminate the vacuum suction of cylinder and film surface, make cut operation steadily, meter is long more accurate.Groove shape in this example is a rectangle, it is of a size of wide 0.05mm-10mm, dark is 0.02mm-10mm, the groove rectangular distribution, during the many more close more then film feeding operation of groove and the area of contact of film more little, owing to the existence of groove, film and the surperficial adsorption phenomena that forms vacuum and produce of the long film feeding roller of meter are eliminated in airiness effectively simultaneously.Adopt groove structure, can make stable working when cutting the easy sorbing material of film class, meter is long more accurate, is suitable for various film based packaging materials, and especially PVA thin, water soluble membrane material cuts (section) operation.
Claims (2)
1, a kind of automatic guillotine is characterized in that with the long film feeding roller of groove structure meter:
A, described film feeding roller surface are provided with uniform groove;
Ditch groove width on b, the long film feeding roller of described meter is 0.05mm-10mm, is 0.02mm-10mm deeply.
2, automatic guillotine according to claim 1 is with the long film feeding roller of groove structure meter, and it is characterized in that: the lip-deep groove shape of the long film feeding roller of described groove structure meter is triangle or circular arc or trapezoidal or rectangle.
