[0001] The utility model relates to the technical field of polarizer production, and discloses an adjustable automatic polarizer cutting device. Background Art

[0002] A polarizer, also known as a polarization filter or polarizing film, is an optical component mainly used to control the polarization direction of light. A polarizer is also one of the key components that make up a liquid crystal display (LCD screen). During the processing of an LCD screen, the polarizer needs to be cut according to the size of the LCD screen.

[0003] The patent with the authorization publication number CN216266167U discloses an adjustable automatic polarizer cutting device, which includes a processing box, a feeding roller arranged on the left side thereof, and a receiving roller arranged on the right side thereof. The receiving roller and the feeding roller are respectively installed on the side surface of the processing box through mounting frames. The shaft ends of the receiving roller and the feeding roller are connected to drive motors, and a polarizing plate is wound between the feeding roller and the receiving roller. This patent proposes to first process the polarizer through negative pressure dust removal before cutting, and then drive the tool holder to move downward by a cutting cylinder to cut the polarizer. However, during the cutting process, due to the inconsistent acting force of the tool holder on the polarizer, the polarizer may not be completely cut and adhesion may occur. If the two polarizers are not separated, it will affect the subsequent processing.

[0004] Therefore, an adjustable automatic polarizer cutting device with a material separating function is needed. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: An adjustable automatic polarizer cutting device. Please refer to Figures 1-6 , which includes a workbench 1, mounting brackets 2, sliding sleeves 3, elastic members 4, conveying rollers 5, pressing rollers 6, a first motor 7, support frames 8, a cylinder 9, a connecting frame 10, a second motor 11, and a cutting knife 12. Mounting brackets 2 are provided on both the left and right sides of the workbench 1 by means of bolt connection. A chute 201 is formed in the mounting bracket 2, and a sliding sleeve 3 is rotatably arranged in the chute 201. Two elastic members 4 are connected between the sliding sleeve 3 and the mounting bracket 2. When it is necessary to cut polarizers of different thicknesses, the sliding sleeve 3 is pulled upward, thereby driving the pressing roller 6 to move upward, and then adjusting the gap between the conveying roller 5 and the pressing roller 6. Then, the polarizer is placed between the conveying roller 5 and the pressing roller 6, and the elastic member 4 returns to its original state to drive the sliding sleeve 3 and the pressing roller 6 to move downward, thereby limiting the polarizer. The two mounting brackets 2 jointly rotatably arrange a conveying roller 5, and the two sliding sleeves 3 jointly arrange a pressing roller 6. A first motor 7 is provided on the right mounting bracket 2 by means of bolt connection, and the output shaft of the first motor 7 is connected to the conveying roller 5. Two support frames 8 are provided on the workbench 1 by means of bolt connection, and a cylinder 9 is jointly provided on the two support frames 8 by means of bolt connection. A connecting frame 10 is connected to the telescopic rod of the cylinder 9. A second motor 11 is provided in the connecting frame 10 by means of bolt connection, and a cutting knife 12 is connected to the output shaft of the second motor 11. A connecting plate 13 is provided on the rear side of the connecting frame 10 by means of bolt connection, and a rotating frame 14 is rotatably arranged on the connecting plate 13. Torsion springs 15 are sleeved on both the left and right sides of the rotating frame 14, and the two ends of the torsion spring 15 are respectively connected to the connecting plate 13 and the rotating frame 14. A rubbing roller 16 is arranged on the rotating frame 14, and a rubber block 27 is arranged on the conveying roller 5. The rubber block 27 reduces the pressure between the pressing roller 6 and the polarizer, avoiding damage to the polarizer caused by excessive pressure. A knife protection sleeve 28 is sleeved on the cutting knife 12. When the cutting device does not need to be adapted, the knife protection sleeve 28 is sleeved on the cutting knife 12, thereby wrapping the blade of the cutting knife 12 and avoiding injury caused by accidentally touching the blade of the cutting knife 12.

[0026] When the polarizer needs to be cut, first place one end of the polarizer between the conveying roller 5 and the pressing roller 6. Then, turn on the first motor 7. The output shaft of the first motor 7 rotates to drive the conveying roller 5, and then the polarizer is conveyed backward. When the polarizer is conveyed below the rear support frame 8, turn on the cylinder 9 and control the telescopic rod of the cylinder 9 to extend, so that the connecting frame 10 drives the cutting knife 12 and the material rubbing wheel 16 to move downward until the cutting knife 12 and the material rubbing wheel 16 contact the polarizer. Continue to control the telescopic rod of the cylinder 9 to extend, so that the cutting knife 12 moves further downward, thereby cutting the polarizer. At the same time, the torsion spring 15 deforms under force, causing the rotating frame 14 to rotate backward, and then separating the two cut polarizers, so as to achieve the purpose of material separation and avoid the adhesion of polarizers affecting subsequent processing. When polarizers of different shapes need to be cut, the second motor 11 can be turned on. The output shaft of the second motor 11 rotates to drive the cutting knife 12, and then the angle of the cutting knife 12 is adjusted to achieve the purpose of flexible cutting and improve the use efficiency of the cutting device.

[0027] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 1 and Figure 7 , two support blocks 17 are fixedly connected to both the left and right sides of the workbench 1. A guide rod 18 is fixedly connected to the left support block 17. A slider 19 is slidably arranged on the guide rod 18. An adjusting screw rod 20 is rotatably arranged on the right support block 17. Another slider 19 is threadedly arranged on the adjusting screw rod 20. The two sliders 19 are jointly fixedly connected with an upper guide roller 2001. A lower guide roller 21 is fixedly connected to the two horizontally aligned support blocks 17.

[0028] Before cutting the polarizer, first rotate the adjusting screw rod 20 to make the slider 19 move upward, and then drive the upper guide roller 2001 to move upward. Then, pass the polarizer through between the upper guide roller 2001 and the lower guide roller 21, and then reverse the adjusting screw rod 20 to make the slider 19 move downward, and then drive the upper guide roller 2001 to move downward, so as to limit the polarizer, make it straighten and keep flat, thus facilitating subsequent cutting.

[0029] Please refer to Figure 1 and Figure 8 , an installation plate 22 is fixedly connected to the left side of the workbench 1. A feeding rod 23 is fixedly connected to the installation plate 22. Threaded parts 24 are provided at both the left and right ends of the feeding rod 23. Adjusting sleeves 25 are threadedly arranged on the threaded parts 24. A limiting knob 26 is threadedly arranged at the right end of the feeding rod 23. The limiting knob 26 limits the right adjusting sleeve 25 to prevent the right adjusting sleeve from falling off.

[0030] When it is necessary to place the polarizer coil, first rotate the adjusting sleeve 25 on the right side to disengage it from the feeding rod 23. Then, sleeved the polarizer coil on the feeding rod 23. Next, place the adjusting sleeve 25 on the right side back on the feeding rod 23. Finally, rotate the two adjusting sleeves 25 simultaneously to limit the polarizer coil, so that the feeding rod 23 can place polarizer coils of different widths.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
