Technical Field
[0001] The present invention belongs to the technical field of release film die-cutting machines, and in particular relates to a release film die-cutting machine for producing V-shaped warped edges and a method of using the same. Background Art
[0002] The release film die-cutting machine is a device used for precision die-cutting of release films and related composite materials. During the die-cutting process, it drives the mold roller to rotate through a motor, coordinates the synchronous feeding of the release film and the bonding material (such as double-sided tape), and performs die-cutting operations according to the preset step distance. It can achieve high-precision cutting (accuracy can reach 0.05 mm). At the same time, the tightness of the release film and double-sided tape is controlled by the adjustment mechanism to avoid material loosening and ensure die-cutting quality. This equipment is widely used in electronics, packaging, automobiles, medical and other fields. For example, in the electronics industry, it is used for circuit board manufacturing and electronic component packaging; in the packaging field, it is used for processing high-end food and pharmaceutical packaging materials; in automobile manufacturing, it is used for interior decoration molding and body film protection.
[0003] In actual use, existing release film die-cutting machines are passive peeling machines that rely on manual intervention or material property adjustment and cannot actively overcome interfacial adhesion. This leads to repeated anti-release problems and a high risk of customer line downtime, affecting subsequent automated production. The pre-peeling process also increases labor costs and is not conducive to staff use. In view of this, we propose a release film die-cutting machine for producing V-shaped warped edges and a method for using the same. Summary of the Invention

[0006] In this technical solution, the release film is sleeved on the unwinding roller, and one end of the release film is fixed on the winding roller. By starting the first motor, the winding roller is driven to rotate, the release film is pulled to move, and the heating plate is started to heat the release film. By starting the electric push rod, the second shell, the die-cutting knife roller and the V-shaped knife roller are moved. The die-cutting knife roller and the V-shaped knife roller move to the surface of the release film. By starting the third motor, the driving gear is driven to rotate, and the two driven gears, the die-cutting knife roller and the V-shaped knife roller are driven to rotate at the same time. Rotation: Through the rotation of the V-shaped tool roller, the blade penetrates the release film coating without damaging the substrate. The film material undergoes plastic deformation to form an integrated V-shaped groove. The release film can be die-cut by rotating the die-cutting tool roller. Through the above structure, the integrated 45-degree V-shaped groove can be simultaneously processed on the release film. During peeling, the horizontal force is converted into a vertical upward force by using the principle of inclined plane mechanics, which completely solves the anti-release problem and prevents product displacement, thereby facilitating use by the staff.
[0007] By means of the tension sensor and the detection roller, the tension of the release film can be detected. When the detection causes the tension of the release film to be too high or too low, the second motor is started, the second bidirectional screw rotates, and the two synchronous wheels and the synchronous belt are used to drive the first bidirectional screw to rotate. The two first threaded sleeves move oppositely to the first rotating frame, driving the second rotating frame, the first shell and the pressure roller to move. At this time, the pressure roller can squeeze the release film, thereby achieving the function of adjusting the tension of the release film. By the rotation of the second bidirectional screw, the two second threaded sleeves and the third rotating frame move oppositely to each other. The fourth rotating frame and the heating plate move to the same direction, and the heating plate can always keep in contact with the release film. The above structure can be used to adjust the tension of the release film, thereby avoiding the release film from breaking due to excessive tension or the die-cutting knife roller being unable to die-cut the release film due to low tension during the winding process. At the same time, the heating plate of the device can always keep in contact with the release film, thereby avoiding the problem that the release film is separated from the heating plate when the tension of the release film is adjusted, resulting in the heating plate being unable to heat the release film, thereby facilitating use by the staff.

[0017] In this technical solution, by starting the third motor, the output end of the third motor drives the driving gear to rotate. Since the driving gear and the two driven gears are meshed and connected, the rotation of the driving gear can drive the two driven gears, the die-cutting knife roller and the V-shaped knife roller to rotate at the same time. Through the rotation of the V-shaped knife roller, the blade penetrates the release film coating without damaging the substrate. The film material undergoes plastic deformation to form an integrally formed V-shaped groove. Through the rotation of the die-cutting knife roller, the release film can be die-cut.

[0050] A method for using a release film die-cutting machine for producing V-shaped warped edges comprises the following steps: Step 1: Sleeve the release film onto the unwinding roller 3, and fix one end of the release film onto the winding roller 9; Step 2: Start the first motor 5 to drive the winding roller 9 to rotate and pull the release film to move; Step 3: Start the heating plate 22 to heat the release film; Step 4: Start the electric push rod 29 to drive the die cutting knife roller 33 and the V-shaped knife roller 34 to move to the surface of the release film; Step 5: Start the third motor 35, and through the second rotating assembly, the die cutting roller 33 and the V-shaped cutter roller 34 can be rotated simultaneously; Step 6: By rotating the V-shaped cutter roller 34, the blade penetrates the release film coating without damaging the substrate, causing the film to undergo plastic deformation to form an integrally formed V-shaped groove. Step 7: By rotating the die-cutting roller 33, the release film can be die-cut.
[0051] Working principle: First, put the release film on the unwinding roller 3, and fix one end of the release film on the winding roller 9. By starting the first motor 5, the output end of the first motor 5 can drive the winding roller 9 to rotate, and then the release film can be pulled to move. By starting the heating plate 22, the heating plate 22 can heat the release film. By starting the electric push rod 29, the output end of the electric push rod 29 drives the second shell 30, the die-cutting knife roller 33 and the V-shaped knife roller 34 to move. At this time, the die-cutting knife roller 33 and the V-shaped knife roller 34 move to the surface of the release film. By starting the third motor 35, the output end of the third motor 35 drives the driving gear 36 to rotate. Since the driving gear 36 is connected to the two slave gears, the two slave gears are connected. The movable gears 37 are meshed and connected, and the rotation of the driving gear 36 can drive the two driven gears 37, the die-cutting knife roller 33 and the V-shaped knife roller 34 to rotate simultaneously. Through the rotation of the V-shaped knife roller 34, the blade penetrates the release film coating without damaging the base material. The film material undergoes plastic deformation to form an integrally formed V-shaped groove. Through the rotation of the die-cutting knife roller 33, the release film can be die-cut. Through the above structure, the integrally formed forty-five-degree V-shaped groove can be synchronously processed on the release film. During peeling, the horizontal force is converted into a vertical upward force by using the principle of inclined plane mechanics, which completely solves the anti-release problem and prevents product displacement, thereby facilitating use by the staff.
[0052] By means of the tension sensor 6 and the detection roller 7, the tension of the release film can be detected. When the detection causes the tension of the release film to be too high or too low, the second motor 28 is started, and the output end of the second motor 28 drives the second bidirectional screw 19 to rotate. By means of the two synchronous wheels 25 and the synchronous belt 26 arranged outside the second bidirectional screw 19 and the first bidirectional screw 11, the rotation of the second bidirectional screw 19 can drive the first bidirectional screw 11 to rotate. By means of the rotation of the first bidirectional screw 11, the two first threaded sleeves 12 and the first rotating frame 13 can be driven to move in opposite directions. By means of the first connecting rod 16 arranged between the first rotating frame 13 and the second rotating frame 15, the movement of the first rotating frame 13 can drive the second rotating frame 15, the first shell 14 and the pressure roller 17 to move. At this time, the pressure roller 17 can squeeze the release film, thereby achieving the tension adjustment of the release film. The function of the joint is that the rotation of the second bidirectional screw 19 can drive the two second threaded sleeves 20 and the third rotating frame 21 to move oppositely, and the second connecting rod 24 set on the third rotating frame 21 and the fourth rotating frame 23 can drive the fourth rotating frame 23 and the heating plate 22 to move through the movement of the third rotating frame 21. At this time, the heating plate 22 can always keep in contact with the release film. Through the above structure, the tension of the release film can be adjusted, which avoids the release film from breaking due to excessive tension or the die-cutting knife roll 33 being unable to die-cut the release film due to low tension during the winding process. At the same time, the heating plate 22 of the device can always keep in contact with the release film, avoiding the problem of the release film and the heating plate 22 being separated when the tension of the release film is adjusted, resulting in the heating plate 22 being unable to heat the release film, thereby facilitating the use of the staff.
