Description

Technical Field

[0001] This utility model relates to the field of composite film production technology, specifically to a gloss-enhancing composite film antistatic roller assembly. Background Technology

[0002] Brightness-enhancing composite film is a new type of optical display material with multiple optical properties such as brightening, diffusion, and shielding. Through nanoscale precision composite technology, it integrates optical functional layers such as brightening film, diffusion film, and shielding film at the molecular level to form an integrated structure. This breaks through the physical boundaries of traditional optical film stacking, achieves synergistic enhancement of optical performance, significantly improves the front brightness and color uniformity of the display module, and reduces the energy loss of the light source. During the production process of brightness enhancement composite film, static electricity will be generated by the attachment of charges on the surface. Static electricity will cause dust, fiber and other particles in the environment to be attracted to the film surface, resulting in product defects. As a key piece of equipment in the production of brightness enhancement composite film, the antistatic roller can eliminate static electricity on the surface of the brightness enhancement composite film to improve the product yield. When the antistatic roller of the brightness enhancement composite film is pressing the composite film, because the brightness enhancement composite film itself has a certain thickness, too small a roller gap will generate huge extrusion resistance, causing the composite film to get stuck, wrinkled or even broken at the entrance. Conversely, if the roller gap is increased to solve the problem of the composite film being stuck, the contact pressure and contact area between the antistatic roller and the edge of the composite film will be reduced accordingly, and the effect of static elimination will be greatly reduced. This means that the edge area of ​​the composite film that is inserted first cannot be completely and uniformly eliminated. Therefore, an antistatic roller assembly for brightness enhancement composite film is proposed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide an antistatic roller assembly for a brightening composite film, in order to solve the problem that because the brightening composite film itself has a certain thickness, an excessively small roller gap will generate huge extrusion resistance, causing the composite film to get stuck, wrinkled or even broken at the entrance. Conversely, if the roller gap is increased to solve the problem of the composite film being inserted, the contact pressure and contact area between the antistatic roller and the edge of the composite film will be reduced accordingly when the roller gap is too large, and the effect of static elimination will be greatly reduced, making it impossible for the edge area of ​​the composite film inserted first to be completely and uniformly eliminated.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An antistatic roller assembly for a brightening composite film includes a worktable, a main roller frame, and an antistatic roller. The main roller frame is fixedly connected to the upper end of the worktable, and an antistatic roller is installed on one side of the main roller frame.

[0007] As a further optimization of this utility model, the long shaft, sleeve, and rubber wheel are on the same axis; the side of the rotating sleeve near the rubber wheel is in the same plane as the side of the rotating rod near the rubber wheel; and the side of the rotating rod away from the rubber wheel is in close contact with the transmission belt.

[0008] As a further optimization of this utility model, two elastic ropes are provided, which are symmetrically distributed. A portion of the elastic rope is sleeved on the outside of the limiting post, and one end of the elastic rope is fixedly connected to the limiting rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figure 1-6 This utility model provides a technical solution: An antistatic roller assembly for a brightening composite film includes a worktable 1, a main roller frame 2, and an antistatic roller 3. The main roller frame 2 is fixedly connected to the upper end of the worktable 1, and the antistatic roller 3 is installed on one side of the main roller frame 2. A limit post 4 is fixedly connected to one side of the main roller frame 2. A conveyor roller assembly 5 is fixedly connected to the upper end of the worktable 1. A transmission assembly 6 is fixedly connected to the upper end of the worktable 1. A pressure roller assembly 7 is fixedly connected to the upper end of the worktable 1. The transmission assembly 6 includes a vertical frame 61, a fixed shaft 62 is fixedly connected to one side of the vertical frame 61, a rotating bushing 63 is rotatably connected to the outside of the fixed shaft 62, and an elastic rope 6 is fixedly connected to the outside of the rotating bushing 63. 4. A transmission belt 65 is fitted on the outer side of the rotating bushing 63. A transmission mechanism 66 is installed on the inner side of the transmission belt 65. A support roller 67 is installed on the inner side of the transmission mechanism 66. The pressure roller assembly 7 includes a support frame 71. A short shaft 72 is fixedly connected to the inner side of the support frame 71. A magnetic counterweight 73 is rotatably connected to the outer side of one end of the short shaft 72. A limit rod 74 is fixedly connected to one side of the magnetic counterweight 73. A fixing frame 75 is fixedly connected to the upper end of the support frame 71. An mounting frame 76 is installed on one side of the fixing frame 75. An upper pressure roller 77 is installed on one side of the mounting frame 76. A magnetic counterweight rod 78 is installed on one side of the mounting frame 76.

[0017] As a further implementation of this solution, the included angle between the fixed shaft 62 and the upright 61 is 90°. The central axis of the fixed shaft 62 and the central axis of the rotating bushing 63 are on the same straight line. There are two rotating bushings 63, which are symmetrically distributed on the upper end of the worktable 1. The position of the elastic rope 64 corresponds one-to-one with the position of the rotating bushing 63. This design ensures that the rotating bushing 63 can rotate smoothly around the fixed shaft 62, while ensuring the accuracy and stability of the rotational motion. The symmetrical distribution realizes the balance of the components, ensuring that the entire mechanical system remains stable during operation and avoiding vibration or shaking caused by asymmetry. As a further implementation of this solution, the transmission mechanism 66 includes a long shaft 661, a sleeve 662 rotatably connected to the outside of the long shaft 661, a rubber wheel 663 fixedly connected to one end of the sleeve 662, a rotating sleeve 664 fixedly connected to the outside of the sleeve 662, and a rotating rod 665 fixedly connected to one side of the rotating sleeve 664. The long shaft 661, the sleeve 662, and the rubber wheel 663 are on the same axis. The side of the rotating sleeve 664 near the rubber wheel 663 is in the same plane as the side of the rotating rod 665 near the rubber wheel 663. The side of the rotating rod 665 away from the rubber wheel 663 is in close contact with the transmission belt 65. Through the design of being on the same axis and in the same plane, precise power transmission and control can be achieved, reducing vibration and shaking. The rotating sleeve 664 plays the role of expansion and fixation, transmitting the power of the sleeve 662 to the rotating rod 665. As a further implementation of this solution, two elastic ropes 64 are provided. The two elastic ropes 64 are symmetrically distributed. A part of the elastic rope 64 is sleeved on the outside of the limiting post 4, and one end of the elastic rope 64 is fixedly connected to the limiting rod 74. The setting of the elastic rope 64 makes the movement of the rotating bushing 63 related to the movement of the magnetic counterweight 73. At the same time, the elastic rope 64 can provide better tension buffer to prevent it from breaking. As a further implementation of this scheme, the area of ​​the side of the magnetic counterweight 73 away from the short axis 72 is twice the area of ​​the side of the magnetic counterweight 73 close to the short axis 72. The magnetic counterweight 73 is magnetically attracted to the magnetic counterweight 78 on one side. There are two magnetic counterweights 73, and the distance between the two magnetic counterweights 73 is the same as the length of the magnetic counterweight 78. This arrangement allows the center of gravity of the magnetic counterweight 73 to be far away from the short axis 72, so that it can rotate around the short axis 72 without the action of external force. At the same time, it also enhances the magnetic attraction between the magnetic counterweight and the magnetic counterweight 78. As a further implementation of this solution, two mounting frames 76 are provided and symmetrically distributed at both ends of the upper pressure roller 77 and the magnetic counterweight rod 78. The positions of the fixing frames 75 correspond one-to-one with the positions of the mounting frames 76. The upper pressure roller 77 and the magnetic counterweight rod 78 are parallel to each other. The mass of the upper pressure roller 77 is 1.5 times the mass of the magnetic counterweight rod 78. The symmetrical distribution of the mounting frames 76 can ensure the balance and stability of the structure, so that the upper pressure roller 77 and the magnetic counterweight rod 78 can be evenly stressed during operation, avoiding poor performance of the device due to uneven weight distribution or asymmetry.

[0018] Working process: When the device is working, the brightness enhancement composite film is first placed directly above the conveyor roller in the conveyor roller assembly 5. Then, the motor on one side of the conveyor roller assembly 5 is started, causing the motor to rotate and drive the conveyor roller in the conveyor roller assembly 5 to convey the brightness enhancement composite film. At the same time, the rubber wheel 663 will also rotate due to the friction force applied by the conveyor roller in the conveyor roller assembly 5. The rotation of the rubber wheel 663 will drive the fixedly connected sleeve 662 to rotate. When the sleeve 662 rotates, it will drive the fixedly connected rotating sleeve 664 to rotate. The rotation of the rotating sleeve 664 will drive the support roller 67 to make a circular motion through the fixedly connected rotating rod 665. After the support roller 67 moves a certain distance, it will come to the bottom of the brightness enhancement composite film, providing further support for the brightness enhancement composite film and making the conveying of the brightness enhancement composite film more stable. While the rotating sleeve 664 is rotating, the rotating sleeve 664 will drive the rotating shaft sleeve 63 to rotate through the transmission belt 65. 3. During rotation, the elastic rope 64 will be unwound. As the elastic rope 64 is unwound, the tension generated by the elastic rope 64 on the limiting rod 74 will change. At this time, the magnetic counterweight 73 will be displaced due to its own gravity. Because the short shaft rod 72 restricts the magnetic counterweight 73, the magnetic attraction generated by the limiting rod 74 on the magnetic counterweight rod 78 will be reduced after rotating a certain angle. At this time, the force applied by the upper pressure roller 77 to the mounting frame 76 is greater than the force applied by the magnetic counterweight rod 78 to the mounting frame 76. The mounting frame 76 will rotate on one side of the fixed frame 75 and drive the upper pressure roller 77 to move closer to the antistatic roller 3. At this time, the brightness enhancement composite film just enters the gap between the upper pressure roller 77 and the antistatic roller 3. With the rotation of the antistatic roller 3, static electricity elimination is performed. This effectively solves the problems of jamming, wrinkles, breakage and poor static electricity elimination effect caused by the roller spacing between the rollers in the antistatic roller assembly.
