Description

Technical Field

[0001] This utility model relates to a cutting machine, and more particularly to a cutting machine for processing brightness enhancement film. Background Technology

[0002] Brightness enhancement film, also known as BEF, is an optical film with a uniform prism pattern precisely molded onto the highly transparent PET surface using acrylic resin. When assembled in front of a backlight, it focuses the light emitted by the light source towards the user of the display device, significantly increasing the brightness of the front. Furthermore, light not utilized outside the viewing angle is recycled through light reflection and focused towards the user at the most appropriate angle.

[0003] The production of brightness enhancement film requires the use of a brightness enhancement film processing cutting machine. When using the brightness enhancement film cutting machine, the film is cut directly by a cutting blade, which causes the film to wobble during use, making it impossible to guarantee cutting accuracy and thus reducing the precision of the workpiece processing.

[0004] In the prior art, the utility model patent with patent application number CN202321280033.7 discloses a cutting machine for processing brightness enhancement film. It mainly uses a transmission mechanism to drive the moving sleeve, so that the moving sleeve drives the cutting blade to move left and right to cut the workpiece. The pressing mechanism can fix the workpiece to ensure cutting accuracy. The brightness enhancement film will not shake when the user uses it, which can ensure cutting accuracy and thus improve the accuracy of workpiece processing.

[0005] However, the above-mentioned technologies cannot achieve automatic cutting of the brightness enhancement film, and the cutting efficiency is slow. Utility Model Content

[0006] The main purpose of this invention is to propose a cutting machine for processing brightness enhancement film, which aims to solve the technical problems of poor cutting accuracy and slow cutting efficiency caused by easy shaking during the cutting of existing brightness enhancement films.

[0028] This utility model proposes a cutting machine for processing brightness enhancement film.

[0029] like Figure 1As shown in one embodiment of this utility model, a cutting machine for processing brightness enhancement film includes a base 1.

After the cutting component 10 cuts, the material pieces fall into the receiving box.

[0030] In this embodiment, the brightness enhancement film roll is mounted on the feeding shaft 4, and then the brightness enhancement film strip is conveyed to the support plate 5 through the first rotating shaft 6, the second rotating shaft 7, and the third rotating shaft 8. The film sheet is then pressed and fixed by the pressing component 9, and then cut by the cutting component 10, thereby realizing the automatic cutting of the brightness enhancement film sheet, which greatly increases the cutting efficiency. At the same time, the pressing component 9 can fix the film sheet to ensure cutting accuracy and prevent the brightness enhancement film from shaking during cutting, thus ensuring cutting accuracy and improving the workpiece processing accuracy. In addition, the rotating arm 3 is connected to the output rotation, and the angle of the feeding shaft 4 can be adjusted as needed, so that the position of the film roll mounted on the feeding shaft 4 can be adjusted relative to the frame. Thus, the rotating arm 3 can be adjusted to a suitable position according to different space requirements or loading and unloading requirements. When the user's application scenario changes, the feeding shaft can be quickly adjusted to meet the compatibility requirements of multiple scenarios and adapt to various application scenarios.

[0031] Preferably, such as Figure 2 As shown, a rotating groove 31 is provided at the end of the rotating arm 3 away from the loading shaft 4. A rotating column is fixed on the vertical plate 2.

The drive cylinder 12 is fixedly connected to the mounting plate, and the cutting blade 13 is fixedly connected to the output end of the drive cylinder 12.

[0035] Alternatively, the drive cylinder 12 can be replaced with a hydraulic cylinder or oil cylinder, or a structure in which a motor drives a lead screw to drive the pressing plate 92 can be adopted.

[0036] Preferably, such as Figure 4 As shown, the support plate 5 is provided with guide plates 51 on both sides of the opposite side of the light enhancement film conveying path. The support plate 5 has strip-shaped through holes on both sides. Both guide plates 51 have fixing holes. The two guide plates 51 are installed at the strip-shaped through holes by bolts.

[0037] Preferably, such as Figure 4 As shown, pressure strips 52 are rotatably connected to both ends of the two guide plates 51. The pressure strips 52 are mounted on the guide plates 51 by hinges and are used to press the upper end of the brightness enhancement film to make it flatter and facilitate precise cutting.

[0038] Preferably, adjusting rings 71 are fitted at both ends of the first rotating shaft 6, both ends of the second rotating shaft 7, and both ends of the third rotating shaft 8. The adjusting rings 71 are fixed to the corresponding rotating shafts by bolts.

The width between the adjusting rings 71 can be adjusted to accommodate the width of different sized sheet materials, and the scale strips 53 can more conveniently adjust the position of the guide plates 51.

[0039] Preferably, the upper ends of the first rotating shaft 6 and the third rotating shaft 8 are flush with the upper surface of the support plate 5, and the second rotating shaft 7 is lower than the upper surface of the support plate 5.

During feeding, the light-enhancing film roll is installed on the loading shaft 4, one end of the film is pulled out and passed over the upper end of the first rotating shaft 6 and pulled down to pass around the lower end of the second rotating shaft 7. The film is then pulled up and passed over the upper end of the third rotating shaft 8 to be pulled onto the support plate 5. Finally, the pressing strip 52 presses the film in the direction to complete the feeding.

[0040] Preferably, the material support plate 5 is provided with a plurality of suction holes 55, each of which is connected to a vacuum pump. The lower end of the material sheet is sucked up through the suction holes 55, making the material sheet flatter and fixing it.

The cutting pad 54 can be made of polyethylene (PE), polypropylene (PP), or natural rubber (NR). The support plate 5 is provided with an installation groove, and the cutting pad 54 is embedded in the installation groove and the upper end surface of the cutting pad 54 is flush with the upper end surface of the support plate 5. The cutting pad 54 can better cut the light-enhancing film sheet.

[0042] Specifically, the working principle and usage process of this utility model are as follows: By loading the brightness enhancement film roll onto the loading shaft 4, and then conveying the brightness enhancement film strip to the support plate 5 through the first rotating shaft 6, the second rotating shaft 7, and the third rotating shaft 8, the film sheet is pressed and fixed by the pressing component 9, and then cut by the cutting component 10, thereby realizing the automatic cutting of the brightness enhancement film sheet, greatly increasing the cutting efficiency. At the same time, the pressing component 9 can fix the film sheet to ensure cutting accuracy and prevent the brightness enhancement film from shaking during cutting, thus ensuring cutting accuracy and improving the precision of workpiece processing. In addition, through the rotating arm 3 connected to the output rotation, the angle of the loading shaft 4 can be adjusted as needed, so that the position of the roll installed on the loading shaft 4 can be adjusted relative to the frame. Thus, the rotating arm 3 can be adjusted to a suitable position according to different space requirements or loading and unloading requirements. When the user's application scenario changes, the feeding shaft can be quickly adjusted to meet the compatibility requirements of multiple scenarios and adapt to various application scenarios.
