[0026] For examples, please refer to Figs. 1-3 This utility model provides a technical solution:

[0027] A tactile film anti-scratch coating machine has an unwinding mechanism comprising a base 1, a first support 101 at the top of the base 1, a first rotating frame 102 on one side of the first support 101, a slot 103 near the center of the first rotating frame 102, a second support 2 on one side of the first support 101, a second rotating frame 201 on the second support 2, a drive motor 202 near the center of the second rotating frame 201, symmetrically provided receiving cavities 3 at the top and bottom of the first rotating frame 102 and the second rotating frame 201, and a rotating rod 301 between the two receiving cavities 3, with the two ends of the rotating rod 301... A limiting hole 302 is provided, and an unwinding roller 303 is provided outside the rotating rod 301. A cover cylinder 304 is provided on the top of the receiving cavity 3. A pressure plate 305 is provided on one side of the cover cylinder 304. A limiting cavity 306 is provided on one side of the receiving cavity 3. An avoidance hole 307 is provided through the pressure plate 305. A cylinder 308 is symmetrically fixed on one side wall of the top and bottom of the first rotating frame 102 and the second rotating frame 201. A support column 4 is symmetrically provided on the top and bottom of the first rotating frame 102 and the second rotating frame 201. A support rod 401 is provided on the top of the support column 4. A rotating groove is provided on the inner side wall of the support rod 401 and near the top of the support column 4. 402, the outside of the rotating trough 402 is provided with several ball bearings 403, the inside of the fixed cylinder 308 and one end of the support rod 401 are respectively provided with limiting rods 5, the outside of the limiting rods 5 are provided with limiting plates 501, the top of the limiting plates 501 is provided with tension springs 502, and the top of the limiting rods 5 is provided with pull plates 503. The film material is conveyed to the coating machine by the conveying mechanism for coating. During the coating process, the film material outside the unwinding roller 303 is continuously consumed until it is exhausted. At the same time, the laser rangefinder 105 will continuously monitor the distance between the laser rangefinder 105 and the film material until the preset value is reached. The control panel will then warn that further adjustments are needed. To replace it, first start the drive motor 202 to drive the rotating frame to rotate, which will rotate the unwinding roller 303 with full film material at the bottom to the top, and the unwinding roller without film material at the top to the bottom to the bottom. The unwinding roller 303 with full film material continues to work. The bottom needs to be replaced. The replacement process is to pull the pull plate 503 at the end of the fixed cylinder 308. At this time, the limit rod 5 will disengage from the positioning hole. Then pull the pull plate at the end of the support rod 401 to disengage the limit rod from the limit cavity 306. Then rotate the support rod 401 and open the cover cylinder 304 to release the limit on the rotating rod 301. Replace with a new rotating rod 301 and operate in reverse to limit it.

[0028] The first bracket 101 has a fixed rod on one side, and the first rotating frame 102 has a sleeve on one side. The inner side wall of the sleeve and the outer side of the fixed rod have rotating grooves. Several steel balls are arranged inside the rotating grooves. The sleeve can rotate along the central axis of the fixed rod, and the fixed rod is set through the slot 103. The output end of the drive motor 202 is fixedly connected to the second rotating frame 201, so that the two rotating frames can be driven by the drive motor 202 without affecting the normal operation of the laser rangefinder 105. The laser rangefinder 105 is set at one end of the fixed rod. The laser rangefinder can accurately measure the remaining film material on the unwinding roller. The cavity 3 has a fixed post inside, and the limiting hole 302 is adapted to the fixed post to limit the position of the rotating rod. The cover cylinder 304 and the receiving cavity 3 are equipped with pressure pads. The cover cylinder and pressure pads further enhance the stability of the unwinding roller. The cover cylinder 304 is rotatably connected to the first rotating frame 102 and the second rotating frame 201 by hinges, which facilitates the quick closing of the cover cylinder 304 and the receiving cavity to limit the position of the rotating rod. One of the limiting rods 5 is provided with a positioning hole, and the two limiting rods 5 are fitted together. One end of the tension spring 502 is fixedly connected to the fixed cylinder 308 and the support rod 401 respectively. The position of the rotating rod is limited by the fit between the two limiting rods. The base 1 is equipped with a battery and a control panel. The control panel is electrically connected to the battery and to the drive motor 202 and the laser rangefinder 105, which facilitates the opening and closing of the components.

[0029] The working process of this utility model is as follows: When using the unwinding mechanism of this tactile anti-scratch film coating machine, the film material is first conveyed to the coating machine by the conveying mechanism for coating. During the coating process, the film material outside the unwinding roller 303 is continuously consumed until it is exhausted. At the same time, the laser rangefinder 105 continuously monitors the distance between the laser rangefinder 105 and the film material until a preset value is reached. The control panel then warns that replacement is needed. First, the drive motor 202 is started to drive the rotating frame to rotate, and the unwinding roller 303 with the full film material below is unwound. 3. Rotate the top. The unwinding roller without film material will turn down, and the unwinding roller 303 with full film material will continue to work. The bottom needs to be replaced. The replacement process is to pull the pull plate 503 at the end of the fixed cylinder 308. At this time, the limiting rod 5 will disengage from the positioning hole. Then pull the pull plate at the end of the support rod 401 to disengage the limiting rod from the limiting cavity 306. Then rotate the support rod 401 and open the cover cylinder 304 to release the limitation on the rotating rod 301. Replace with a new rotating rod 301 and operate in the opposite direction to limit it.
