Description

Technical Field

[0001] This utility model relates to the field of liquid crystal reflective film processing technology, specifically to a liquid crystal reflective film processing feed adjustment device. Background Technology

[0002] Liquid crystal reflective film is an optical material used in the backlight module of liquid crystal displays. Its main function is to reflect light leaking through the light guide plate back, reducing light loss and thus increasing backlight brightness. The reflectivity of the reflective film is usually required to be above 96%. By coating with a high-reflectivity coating or mirror silver plating, the reflectivity can be increased to over 97%, or even reach 100%. In order to improve the processing efficiency of liquid crystal reflective film, a feeding adjustment device is needed. However, existing feeding adjustment devices still have the following shortcomings:

[0003] When existing feeding adjustment equipment is used, most of the feeding adjustment equipment is not convenient to adapt to the adjustment of the spacing between the feeding rollers for liquid crystal reflective films of different thicknesses. As a result, the surface of the liquid crystal reflective film is easily damaged by excessive pressure during the conveying process, which affects the normal conveying of the liquid crystal reflective film and causes the practicality of the feeding adjustment equipment to decrease and the efficiency of use to decrease.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a liquid crystal reflective film processing feeding adjustment device. Utility Model Content

[0005] The purpose of this invention is to provide a liquid crystal reflective film processing feeding adjustment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid crystal reflective film processing feeding adjustment device, comprising a main frame and a feeding assembly. Support columns are installed at the bottom of the main frame. Feeding assemblies are arranged on both sides inside the main frame. Each feeding assembly includes a mounting plate, a spring damping rod, a movable slider, a movable feeding roller, a limiting slider, a limiting through hole, a limiting rod, a servo motor, and a fixed feeding roller. A spring damping rod is arranged at the lower center of the mounting plate, and a movable slider is installed at the front end of the spring damping rod. A movable feeding roller is connected to the outer side of the movable slider, and a limiting slider is installed on the inner side of the movable slider. A limiting through hole is opened inside the limiting slider, and a limiting rod is connected inside the limiting through hole. Servo motors are installed on both outer sides of the main frame, and a fixed feeding roller is connected to the front end of each servo motor. A tensioning assembly is arranged at the middle of the interior of the main frame.

[0007] Furthermore, the outer side of the movable slider is horizontally distributed with the outer side of the mounting plate, and the movable slider is elastically connected to the mounting plate through a spring damping rod.

[0008] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting rod, and the limiting rod is embeddedly connected to the limiting slider through the limiting through hole.

[0009] Furthermore, there are two fixed feeding rollers, and the two fixed feeding rollers are symmetrically arranged on both sides of the main frame with respect to the side center axis of the main frame.

[0010] Furthermore, the tensioning assembly includes a fixed plate, an electric telescopic rod, and a mounting slider. The electric telescopic rod is installed at the lower end of the fixed plate, and a mounting slider is provided at the front end of the electric telescopic rod.

[0011] Furthermore, the tensioning assembly also includes a tensioning roller, a first conveying roller, and a second conveying roller, and the tensioning roller is connected to the inner side of the mounting slider. At the same time, the first conveying roller is distributed on the left side of the tensioning roller, and the second conveying roller is distributed on the right side of the tensioning roller.

[0012] Furthermore, the electric telescopic rod and the mounting slider are arranged perpendicularly, and the electric telescopic rod and the mounting slider are fixedly connected by bolts.

[0013] Furthermore, the outer side of the mounting slider and the outer side of the tensioning roller are horizontally distributed, and the tensioning roller is rotatably connected to the mounting slider via a rotating shaft.

[0014] This utility model provides a feeding and adjusting device for processing liquid crystal reflective films, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the feeding component, enables the fixed feeding roller to rotate via a servo motor when the liquid crystal reflective film processing feeding adjustment equipment is in use. The movable slider is elastically connected to the mounting plate via a spring damping rod. At the same time, the limiting through hole and the limiting rod increase the stability of the limiting slider during movement, thereby preventing the position deviation of the movable slider during elastic movement. The movable feeding roller, together with the fixed feeding roller, can feed and transport the liquid crystal reflective film and can be adapted to the processing of liquid crystal reflective films of different thicknesses, further improving the flexibility and responsiveness of the feeding adjustment equipment during use.

[0016] 2. By incorporating a tensioning component, this invention enables the electric telescopic rod to move the mounting slider during the use of the liquid crystal reflective film processing feed adjustment equipment. This allows for adjustment of the tensioning roller's position, thereby controlling the tension of the liquid crystal reflective film and preventing inconsistent tension during feeding. Simultaneously, the first and second conveying rollers work together to stably transport the liquid crystal reflective film, preventing height variations during transport from affecting subsequent material feeding and further enhancing the overall practicality and efficiency of the feed adjustment equipment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

The feeding assembly 3 includes a mounting plate 301, a spring damping rod 302, a movable slider 303, a movable feeding roller 304, a limiting slider 305, a limiting through hole 306, a limiting rod 307, a servo motor 308, and a fixed feeding roller 309.

Servo motors 308 are installed on both sides of the main frame 1, and a fixed material conveying roller 309 is connected to the front end of each servo motor 308. The outer side of the movable slider 303 is horizontally distributed with the outer side of the mounting plate 301, and the movable slider 303 is elastically connected to the mounting plate 301 via a spring damping rod 302. The internal dimensions of the limit through hole 306 are adapted to the external dimensions of the limit rod 307, and the limit rod 307 is connected to the main frame 1 via the limit through hole 306. The limiting slider 305 is embedded. Two fixed feeding rollers 309 are provided, symmetrically arranged on both sides of the main frame 1 along its side centerline. A servo motor 308 is fixedly mounted on both sides of the main frame 1 using fastening bolts. The output shaft of the servo motor 308 is connected to the fixed feeding rollers 309 via a coupling. The servo motor 308 drives the fixed feeding rollers 309 to rotate. The mounting plate 301 is fixedly mounted on both sides of the main frame 1, and a spring damping rod 302 is fixedly mounted on the lower end of the mounting plate 301. The spring damping rod 302 allows the movable slider to move... Block 303 is elastically connected to mounting plate 301. At the same time, the internal dimensions of the limiting through hole 306 opened inside the limiting slider 305 at the rear end of the movable slider 303 are adapted to the external dimensions of the limiting rod 307. Thus, the limiting through hole 306, in conjunction with the limiting rod 307, increases the stability of the limiting slider 305 during movement, thereby preventing positional deviation when the movable slider 303 moves elastically. Meanwhile, the movable feeding roller 304, in conjunction with the fixed feeding roller 309, can feed and transport the liquid crystal reflective film, and can adapt to the processing of liquid crystal reflective films of different thicknesses, further improving the flexibility and dynamism of the feeding adjustment equipment during use.

[0023] like Figures 1 to 3As shown, a tensioning assembly 4 is installed in the middle of the main frame 1. The tensioning assembly 4 includes a fixed plate 401, an electric telescopic rod 402, and a mounting slider 403. The electric telescopic rod 402 is installed at the lower end of the fixed plate 401, and the mounting slider 403 is installed at the front end of the electric telescopic rod 402. The tensioning assembly 4 also includes a tension roller 404, a first conveying roller 405, and a second conveying roller 406.

The tension roller 404 is used to control the tension of the liquid crystal reflective film, thereby avoiding uneven tension during the feeding process of the liquid crystal reflective film. At the same time, the first conveying roller 405 and the second conveying roller 406 can stably convey the liquid crystal reflective film, avoiding the height change of the liquid crystal reflective film during the conveying process from affecting the subsequent material conveying, further improving the overall practicality and efficiency of the feeding adjustment equipment.

[0024] In summary, this liquid crystal reflective film processing feeding adjustment equipment, during use, firstly enhances the stability of the main frame 1 through the support column 2. Then, the servo motor 308 drives the fixed feed roller 309 to rotate, fixing the mounting plate 301 to both sides inside the main frame 1. The movable slider 303 is elastically connected to the mounting plate 301 via the spring damping rod 302. Simultaneously, the limiting through hole 306, in conjunction with the limiting rod 307, increases the stability of the limiting slider 305 during movement, thus preventing positional deviation of the movable slider 303 during elastic movement. Furthermore, the movable feed roller 304, in conjunction with the fixed feed roller 309, can... The liquid crystal reflective film is fed and conveyed, and can be adapted to process liquid crystal reflective films of different thicknesses. Then, the electric telescopic rod 402 drives the installation slider 403 to move, thereby adjusting the position of the tension roller 404. The tension roller 404 is used to control the tension of the liquid crystal reflective film, thereby avoiding uneven tension during the feeding process.
