However, this design is prone to vibration, misalignment, or even breakage when the film material is heavy, due to uneven stress on the spindle or insufficient support. This affects the flatness and precision of the optical film, reducing product quality and production efficiency. Therefore, we have made improvements and proposed an optical film unwinding device.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As described in the background section, traditional unwinding devices often use a single motor to drive the spindle to unwind the film. However, when the film material is heavy, this design is prone to vibration, displacement or even breakage due to uneven force on the spindle or lack of sufficient support, which affects the flatness and precision of the optical film and reduces product quality and production efficiency.

[0020] To solve this technical problem, this utility model provides an optical film unwinding device.

[0021] For details, please refer to Figures 1-4 The optical film unwinding device specifically includes: The base frame 1 and a first support frame 101 fixedly installed on one side of the top of the base frame 1. A driving component is provided on the first support frame 101. The driving component is connected to a support spindle 102.

[0022] The optical film unwinding device provided by this utility model can support the main support shaft 102 through the provided support member, support rod 107 and support roller 205, effectively distributing the force on the main support shaft 102 during the unwinding process, reducing the bending and vibration of the main support shaft 102 caused by gravity or tension, ensuring the smooth unfolding of the optical film during the unwinding process, and the stable unwinding process ensures the flatness and precision of the optical film, meeting the requirements of high-precision processing, and improving the quality and market competitiveness of the final product.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-4 An optical film unwinding device includes a base frame 1 and a first support frame 101 fixedly installed on one side of the top of the base frame 1. A driving component is provided on the first support frame 101, and the driving component is connected to a support spindle 102. A support rod 107 is fixedly connected to one end of the support spindle 102. A support member is provided on the base frame 1, and two support rollers 205 are provided on the top of the support member. The support rod 107 is rotatably connected between the two support rollers 205. This application can support the support spindle 102 through the provided support member, support rod 107 and support rollers 205, effectively distributing the force on the support spindle 102 during the unwinding process, reducing the bending and vibration of the support spindle 102 caused by gravity or tension, ensuring the smooth unfolding of the optical film during the unwinding process, and the stable unwinding process ensures the flatness and precision of the optical film, meets the requirements of high-precision processing, and improves the quality and market competitiveness of the final product.

[0027] Furthermore, such as Figures 1-4 As shown, the support includes two support shafts 2 respectively installed on both sides of the base frame 1. Sleeves 201 are slidably connected to the outer surfaces of the two support shafts 2. A base 202 is fixedly connected between the two sleeves 201. The support shafts 2 and sleeves 201 cooperate with each other to support the base 202, and the sleeves 201 can move on the outer surfaces of the support shafts 2.

[0028] Furthermore, such as Figures 1-4 As shown, a connecting shaft 203 is installed on the base 202. The outer surface of the connecting shaft 203 is fitted with a second support frame 204 through a bearing. Two support rollers 205 are both set on the second support frame 204. The second support frame 204 can be connected to the sleeve 201 through the connecting shaft 203. When the base 202 moves and the support rollers 205 are separated from the support rod 107, the second support frame 204 can be rotated around the connecting shaft 203 as the center, so that the second support frame 204 can be rotated to the side, thereby avoiding the second support frame 204 from affecting the loading and unloading of the optical film roll.

[0029] Furthermore, such as Figure 1As shown, a handle 207 is installed on the side of the second support frame 204. The handle 207 is designed to provide a point of leverage for workers when moving the second support frame 204, so as to facilitate workers' operation.

[0030] Furthermore, such as Figure 4 As shown, a through hole is provided on the base 202, and a hand-tightening bolt 206 is provided on the second support frame 204. The hand-tightening bolt 206 passes through the second support frame 204 and is inserted into the through hole. The second support frame 204 and the base 202 can be fixed together by the hand-tightening bolt 206. Tightening the hand-tightening bolt 206 separates the hand-tightening bolt 206 from the through hole, so that the second support frame 204 can be rotated around the shaft 203.

[0031] Example 2 further optimizes the optical film unwinding device provided in Example 1, specifically, as follows: Figure 1 As shown, a fixed disk 103 is fixedly sleeved on the outer surface of the support spindle 102, and a movable disk 104 is threadedly connected to the outer surface of the support spindle 102. The movable disk 104 is located between the fixed disk 103 and the support rod 107. The support spindle 102 can support the roll of the optical film, while the fixed disk 103 and the movable disk 104 cooperate with each other to fix the roll of the optical film.

[0032] Furthermore, such as Figures 1-2 As shown, the driving component is a drive motor 106, which is mounted on the side of the first support frame 101. The output shaft of the drive motor 106 is connected to one end of the support spindle 102, and the drive motor 106 can drive the support spindle 102 to rotate.

[0033] Furthermore, such as Figure 1 As shown, a bearing is provided between the outer surface of the support spindle 102 and the first support frame 101, and the support spindle 102 can be supported by the first support frame 101.

[0034] Example 3 further optimizes the optical film unwinding device provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, a limiting component is provided on the first support frame 101. The limiting component is located above the support spindle 102. The limiting component is used to limit the optical film when it is unwound, so that the output trajectory of the optical film is more stable when it is unwound.

[0035] Furthermore, such as Figure 1 As shown, the limiting component includes a cylinder 3 installed on the side of the first support frame 101. The piston rod of the cylinder 3 is connected to a connecting rod 301. The outer surface of the connecting rod 301 is fitted with a roller 302 through a bearing. The cylinder 3 can drive the connecting rod 301 and the roller 302 to move up and down to adjust the height of the roller 302.

[0036] The optical film unwinding device provided by this utility model is used as follows: Push the second support frame 204 to separate the support roller 205 from the support rod 107. After unscrewing the hand-tightening bolt 206, rotate the second support frame 204 to the side with the connecting shaft 203 as the center. Unscrew the movable disc 104 and place the roll with the optical film on the outer surface of the support main shaft 102. Then screw the movable disc 104 onto the support main shaft 102. The roll with the optical film is clamped and fixed by the fixed disc 103 and the movable disc 104. Rotate the second support frame 204 with the connecting shaft 203 as the center to reset the second support frame 204. Tighten the hand-tightening bolt 206 to connect the hand-tightening bolt 206 to the through hole. Push the support roller 205 towards the support rod 107 to support the support rod 107. After the optical film passes over the top of the roller 302, it is led out. The drive motor 106 drives the support main shaft 102 and the roll to rotate to unwind the optical film.
