[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A curved surface film feeding device, such as Figure 1-Figure 4As shown, it includes a box body 1, a mounting frame 2 is fixedly connected to the top of the box body 1, a first mounting roller 3 is rotatably connected to one side of the top of the mounting frame 2, a first rotating roller 4 is arranged below one side of the first mounting roller 3, a first tension component 5 is arranged between the first mounting roller 3 and the first rotating roller 4, the first tension component 5 includes a rotating shaft 501, a first connecting rod 502 and a second connecting rod 503 are fixedly connected to one side of the rotating shaft 501, a first pressing wheel 504 is rotatably connected between the first connecting rod 502 and the second connecting rod 503, and the rotating shaft 501, the first connecting rod 502, and the second connecting rod 503 are rotatably connected. The synergistic effect of the rod 503 and the first pressure wheel 504 can realize the tension adjustment and control of the film material during the transmission process, ensuring that the surface of the film can maintain appropriate tension when the film passes through the first installation roller 3 and the first rotating roller 4, avoiding the film material from stretching and folding due to tension, thereby improving the quality and stability of the film stretching. At the same time, the design of the first connecting rod 502 and the second connecting rod 503 also plays a guiding role for the film material, so that the film can smoothly transition from the first installation roller 3 to the first rotating roller 4, and under the pressure of the first pressure wheel 504, the film can be smoothly stretched.

[0038] See also Figure 1 , Figure 2 and Figure 3 An extension rod 505 is fixedly connected to one side of the back of the rotating shaft 501, and a spring 506 is fixedly connected to one side of the extension rod 505. The fixed connection of the extension rod 505 provides a stable support point for the spring 506, ensuring that the spring 506 can maintain a stable shape and performance during operation, so that the spring 506 can effectively absorb and buffer the impact force and vibration that may be generated by the film material during the transmission process, thereby protecting the film material from damage. At the same time, when the tension of the film material changes, the spring 506 can expand and contract accordingly, and dynamically adjust the tension through its elastic force, thereby ensuring that the film material always maintains a stable tension state during the transmission process, further improving the quality and efficiency of the film pasting.

[0039] See also Figure 1 , Figure 2 and Figure 3 One end of the spring 506 is fixedly connected with a pressure sensor 507, and the pressure sensor 507 is fixedly connected to the mounting bracket 2. Through the pressure sensor 507 fixedly connected to one end of the spring 506, the curved surface film feeding device can monitor the pressure changes on the spring 506 in real time, so that the device can accurately sense the tension changes of the film material during the transmission process, thereby realizing precise control of the tension of the film material. At the same time, since the pressure sensor 507 is fixedly connected to the mounting bracket 2, the stability of the sensor position and the accuracy of the measurement are ensured, which not only reduces the error of the sensor caused by vibration or displacement, but also improves the reliability and durability of the entire device.

[0040] See also Figure 1, Figure 2 and Figure 3 The bottom of the first connecting rod 502 is fixedly connected to a first extension plate 508, and the bottom surface of the first extension plate 508 is engaged with a first rolling ball 509. The fixed connection of the first extension plate 508 provides a stable support platform for the first rolling ball 509, so that the first rolling ball 509 can roll freely on the bottom surface of the first extension plate 508, thereby effectively reducing the friction resistance between the film material and the device. At the same time, the engaging design of the first rolling ball 509 further ensures the stability of its position and the smoothness of its rolling, which not only reduces the wear of the film material during the transmission process, but also improves the transmission efficiency of the film material, making the film pasting process smoother and more efficient.

[0041] See also Figure 1 , Figure 2 and Figure 3 The bottom of the second connecting rod 503 is fixedly connected to a second extension plate 510, and a second rolling ball 511 is engaged with the bottom surface of the second extension plate 510, one of the second rolling balls 511 is in conflict with the first rolling ball 509 and the first rotating roller 4, and the fixed connection of the second extension plate 510 provides stable support for the second rolling ball 511, ensuring that the second rolling ball 511 can roll smoothly on its bottom surface, effectively reducing the friction resistance of the film material when passing under the second connecting rod 503, and improving the transmission efficiency of the film material. At the same time, the conflicting design of one of the second rolling balls 511, the first rolling ball 509 and the first rotating roller 4 forms a smooth transition area, which not only further reduces the resistance of the film material during transmission, but also helps to guide the film material to smoothly enter the first rotating roller 4, thereby improving the stability and quality of the film laminating process.

[0042] See also Figure 1 , Figure 2 and Figure 3 A second rotating roller 7 is arranged below the first rotating roller 4, a partition plate 8 is arranged on one side of the second rotating roller 7, and a detection mechanism 9 is arranged on one side of the partition plate 8. The curved film feeding device provides additional support and transmission path for the film material, which helps to maintain the continuity and stability of the film material during the film pasting process and avoid film pasting problems caused by path interruption or insufficient support. At the same time, the introduction of the partition plate 8 plays a role of isolation and partitioning, realizes the combination of different films and detects their integrity, and then realizes reliable film pasting preparation.

[0043] See also Figure 1 , Figure 2 and Figure 3A third rotating roller 10 is arranged on one side of the partition plate 8, a fourth rotating roller 11 is arranged on one side of the third rotating roller 10, a fifth rotating roller 12 is arranged above the fourth rotating roller 11, and a second mounting roller 13 is arranged above one side of the fifth rotating roller 12. By arranging the third rotating roller 10, the fourth rotating roller 11, the fifth rotating roller 12 and the second mounting roller 13, a more complex and sophisticated transmission path is provided for the film material, so that the film material can be adjusted and guided by multiple rollers before film pasting, so as to more accurately match it to the curved surface to be pasted, thereby improving the accuracy and quality of film pasting. At the same time, when the film material passes through these rollers, its tension will be gradually adjusted and balanced, so as to ensure that the film material can maintain the best tension state when film pasting, and can avoid problems such as wrinkling and stretching of the film material caused by uneven tension.

[0044] The implementation principle of the utility model is as follows: first, the film is pulled through the bottom of the first tension component 5, so that the first pressure wheel 504 can press on the film by its own weight, so that there is a downward force at the center of the film, and this force makes the film concave downward, and the concave film passes through the first pressure wheel 504 and follows the subsequent first extension plate 508 and second extension plate 510, and enters the first rotating roller 4 in a diffused state, and the first extension plate 508 and the second extension plate 510 prevent the film from rolling up, and the first rolling ball 509 and the second rolling ball 511 can reduce the resistance of the film passing through the first tension component 5;

[0045] The pressure sensor 507 can effectively monitor the force on the film roll to ensure that the film roll can maintain a normal working state.

By setting the second tension component 6, additional tension control is provided for the film material between the first installation roller 3 and the first rotating roller 4, so that the device can adjust the tension of the film material according to different situations, so as to more flexibly adapt to different film laminating requirements. At the same time, the clamping rod 604 is rotatably connected to the rotating base 601 through the torsion shaft, so that the clamping rod 604 can be easily adjusted when needed, which simplifies the effect of adjusting the position of the second pressure wheel 607, so that the second pressure wheel 607 can be simply adjusted in position.

[0048] See also Figure 4, one end of the rotating base 601 is slidably connected with a sliding column 602, and slots 603 are provided on the upper and lower sides of the sliding column 602, and the slots 603 are adapted to one end of the clamping rod 604. Through the sliding connection design between the sliding column 602 and the rotating base 601, a convenient adjustment function is provided. When the position of the second pressure wheel 607 needs to be adjusted, the operator can easily move the sliding column 602, thereby changing the position of the second pressure wheel 607, and realizing rapid adjustment of the clamping position. At the same time, the adaptive design of the slot 603 and the clamping rod 604, when the sliding column 602 moves to the appropriate position, the clamping rod 604 can be easily inserted into the corresponding slot 603, fixing the sliding column 602 at the desired position, thereby ensuring the position accuracy of the second pressure wheel 607.

[0049] See also Figure 4 A third connecting rod 605 and a fourth connecting rod 606 are fixedly connected to one side of the sliding column 602, and a second pressure wheel 607 is rotatably connected between the third connecting rod 605 and the fourth connecting rod 606. Through the fixed connection between the third connecting rod 605 and the fourth connecting rod 606 and the second pressure wheel 607 rotatably connected therebetween, the second tension component 6 of the curved surface film feeding device can achieve stable pressing of the film material. At the same time, the rotatable connection design of the second pressure wheel 607 enables it to rotate freely with the transmission of the film material, thereby reducing the friction resistance between the film material and the second pressure wheel 607 and improving the transmission efficiency of the film material.

[0050] The implementation principle of the utility model is: first, when adjusting the position of the second pressure wheel 607, pull up the clamping rod 604, pull the sliding column 602 outward to a suitable position, release the clamping rod 604, and one end of the clamping rod 604 is inserted into the inside of the clamping groove 603 to clamp the sliding column 602 at the specified position.
