Abstract
The invention discloses a cutting method of a thin film. The method comprises the following concrete steps of step 1, installing a thin film to be cut on an unwinding roller; step 2,sequentially winding the thin film to be cut around guide rollers and a cutting roller, and finally, respectively winding and fixing the two pieces of thin films formed after cutting through the cutter roller on two winding rollers; step 3, switching on tension controllers of the unwinding roller and the winding rollers, and adjusting the tension strength of the thin films through adjusting the tension controllers of the unwinding roller and the winding rollers so as to adjust the smoothness of the thin films; step 4, switching on a motor of a thin film continuous winding device to enable the guide rollers to rotate, utilizing the guide rollers to drive the thin films to be wound and conveyed from the unwinding roller to the winding rollers, and utilizing a cutting edge of the cutter roller to continuously cut the thin film so as to convey and cut the thin film to be cut. The cutting method of the thin film can be applicable to cutting various flexible thin film materials, and since the cutting edge of the cutting roller adopts a movable design, the cutting width of the thin film can be adjusted according to concrete needs, and the wider thin film materials can be cut into the thin films with narrower width.
Description
Technical field
The present invention relates to film slitting technical field, be specifically related to a kind of cutting method of film.
Background technology
The membraneous material such as polyimide, polyester has a wide range of applications in packaging, electronics, aerospace, printing, building materials, agricultural etc., the membraneous material that general industry is produced all has fixing fabric width specification, if fabric width demand and standard specification are not inconsistent, just needing by wider membraneous material by being cut into the membraneous material of less width, therefore just needing fast, film slitting method easily.
Summary of the invention
In view of this, the invention provides a kind of cutting method of film, what the method can be applicable to the fexible film of various wide cut cuts demand.
Realize technical scheme of the present invention as follows:
A cutting method for film, concrete steps are as follows:
Step one, film to be cut is installed on let off roll;
Step 2, film to be cut is reeled through deflector roll successively and cuts roller, finally by cut roller cut after two pieces of films reel respectively and be fixed on two wind-up rolls;
Step 3, open the tension control assembly of let off roll and wind-up roll, adjusted the Tensity size of film by the tension control assembly of adjustment let off roll and wind-up roll, and then the planeness of adjustment film;
Step 4, the motor opening film continuous reeling device make deflector roll rotate, and deflector roll drives film to be reeled tape transport to wind-up roll by let off roll, and the cutting edge that cuts cutting roller continues to cut film, and the tape transport realizing film to be cut cuts.
So far, the cutting process of film is completed.
Further, the tension value of the tension control assembly of wind-up roll is greater than the tension value of the tension control assembly of let off roll.
Further, the cutting edge that cuts cutting roller adopts movable design, and the demand according to cutting size regulates.
Beneficial effect: the present invention is applicable to cutting of the various flexible thin-film material such as polyimide, polyester, because the cutting edge that cuts cutting roller adopts movable design, film slitting width can be adjusted, for wider membraneous material is cut into more narrow wide film according to real needs.

Fig. 1 is the lateral plan of film slitting process.
Fig. 2 is the schematic diagram of film slitting process.
Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
In the present invention, film continuous reeling device comprises let off roll, wind-up roll, deflector roll and cuts roller.Let off roll and wind-up roll are all provided with tension control assembly, can control Tensity size during film folding and unfolding respectively; Cutting roller is add on the basis of original film continuous reeling device, original film continuous reeling device only comprises let off roll, wind-up roll, deflector roll, roller is cut by adding one in original film continuous reeling device, and cut roller cuts cutting edge, make film realize tape transport and cut.The cutting edge that cuts cutting roller adopts movable design, and cutting edge can cut transverse shifting on roller, can regulate according to the demand cutting size.
As depicted in figs. 1 and 2, the invention provides a kind of cutting method of film, concrete steps are as follows:
Step one, film to be cut is installed on let off roll;
Step 2, film to be cut to be reeled deflector roll and cut roller successively, by through cut roller cut cutting edge cut after film reel successively and be fixed on two wind-up rolls;
Step 3, open the tension control assembly of let off roll and wind-up roll, adjust the tension control assembly of let off roll and the tension control assembly of wind-up roll respectively, make the tension value of wind-up roll bigger, the tension value of let off roll is smaller, the Tensity size of film is adjusted by the tension control assembly adjusting let off roll and wind-up roll, and then the planeness of adjustment film;
Step 4, the motor opening film continuous reeling device make deflector roll rotate forward, because wind-up roll tension value is bigger compared with let off roll, utilize the friction force between deflector roll and film, can realize deflector roll drives film by the winding tape transport of let off roll to wind-up roll, if film cannot normal tape transport, the tension force of wind-up roll and let off roll can be increased thus the friction force increased between deflector roll and film simultaneously.In the process, the Tension Difference between wind-up roll and let off roll need regulate in concrete practice, if Tension Difference is excessive, when then deflector roll does not rotate, film will be pulled by wind-up roll, if Tension Difference is too small, then the friction force between deflector roll and film is not enough to make the normal tape transport of film.The setting of deflector roll is to make film with the even tape transport of the rotative speed of deflector roll, and by the tape running speed regulating the rotative speed of deflector roll to regulate film, the cutting edge that cuts cutting roller continues to cut film, and the tape transport finally realizing film to be cut cuts.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
