DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 5, a polarizer cutting device, including a material transport platform 1, said material transport platform 1 is provided with support plates 4 on both sides through hinges 2, said support plates 4 are fixed to the material transport platform 1 by first mounting bolts 3, and the two support plates 4 jointly clamp a feed roller 5 for loading the polarizer roll, and the left and right ends of the feed roller 5 are provided with three groups of first screw holes 501 evenly distributed, and two ends of the feed roller 5 are sleeved with a clamping ring 6, and the clamping ring 6 is threadedly provided with a plurality of second mounting bolts 7, and the number of the second mounting bolts 7 corresponds to the number of the first screw holes 501 in each group, and the second mounting bolts 7 are used to fix the clamping ring 6, and the second mounting bolts 7 are screwed into the first screw holes 501 to achieve the fixing operation of the clamping ring 6, thereby ensuring the stable installation of the polarizer roll on the feed roller 5, and the front side of the material transport platform 1 is fixedly connected to the first mounting bracket 8, and the first mounting bracket 8 is installed on the first motor 9. A guide rod 10 for conveying polarizer is installed on the side, and the guide rod 10 is connected to the output shaft of the first motor 9. A pressing rod 11 for pressing the polarizer is provided on the rear side of the middle part of the transport platform 1. A third mounting bolt 12 is provided on the right side of the rear of the transport platform 1, and the third mounting bolt 12 is threadedly connected to the right end of the pressing rod 11. A first guide rod 13 for guiding the pressing rod 11 is provided on the left side of the rear of the transport platform 1, and the pressing rod 11 can move up and down along the first guide rod 13. A connecting frame 14 symmetrically distributed on the left and right is provided at the rear of the transport platform 1. The two connecting frames 14 are jointly provided with a first cylinder 15, and a cutting knife 16 is provided on the movable rod of the first cylinder 15. The first cylinder 15 can drive the cutting knife 16 to move vertically for cutting operations. The outer cover of the cutting knife 16 is provided with a protective cover 17. When not in use, the protective cover 17 is used to cover the cutting knife 16 for dust prevention.

[0027] When it is necessary to cut the polarizer, first select one side of the support plate 4 to open it, unscrew the corresponding first mounting bolt 3, then remove the corresponding clamping ring 6, put the polarizer roll into the unwinding roller 5, then fix the support plate 4, move the two clamping rings 6 to contact the two ends of the polarizer roll, and turn the second mounting bolt 7 to screw it into the first screw hole 501, thereby fixing the clamping ring 6, completing the installation and limiting work of the polarizer roll to prevent the polarizer roll from moving left and right and affecting the cutting. Then, One end of the polarizer roll is pulled out, passed around the guide rod 10, and then placed between the pressing rod 11 and the surface of the transport platform 1 to be pressed and fixed. The staff starts the first motor 9 and the first cylinder 15. The first motor 9 drives the guide rod 10 to rotate and transport the polarizer roll backward. After being flattened by the pressing rod 11, the polarizer roll is moved to the bottom of the cutting knife 16 for equidistant cutting to obtain the required size specifications. In this way, automatic feeding and cutting of the polarizer are realized, which greatly improves the cutting efficiency and speed.

[0028] Example 2: Based on Example 1, please refer to Figure 3 The front of the transport platform 1 is provided with four guide slots 18 which are symmetrically distributed in pairs. The guide slots 18 are arranged at an angle to facilitate the polarizer to enter the transport platform 1. A guide plate 19 for guiding the polarizer is slidingly provided on the guide slot 18. A fourth mounting bolt 20 is threadedly provided on the guide plate 19. A second bolt hole 21 matching the fourth mounting bolt 20 is provided on the surface of the transport platform 1 on the front side of the guide slot 18.

[0029] Before cutting the polarizer, first rotate the fourth mounting bolt 20 to disengage it from the second bolt hole 21, then adjust the guide plate 19 to a suitable position according to the width of the polarizer roll, and then rotate the fourth mounting bolt 20 in the opposite direction to screw it into the second bolt hole 21, thereby fixing the guide plate 19. In this way, during the polarizer conveying process, the guide plate 19 can limit the position of the left and right sides of the polarizer and guide it to prevent the polarizer from deviating and keep it in the center position to ensure the subsequent cutting effect.

[0030] See also Figure 6 A second mounting bracket 22 is fixedly connected to the rear side of the transport platform 1, and a second motor 23 is installed on the top of the second mounting bracket 22. A material removal rod 24 for removing the polarizer is rotatably installed at the rear of the transport platform 1, and the material removal rod 24 is connected to the output shaft of the second motor 23.

[0031] See also Figure 7 and Figure 8 The top of the bottom plate 25 is provided with a guide plate 35 located on the left and right sides of the first discharge box 28, and the guide plate 35 is used to guide the first discharge box 28.

[0032] When the polaroid is cut, the second motor 23 drives the material removal rod 24 to rotate, so that the material removal rod 24 brings the cut polaroid out and pushes it into the second material discharge box 33, realizing automatic discharge and improving the overall production efficiency. When the polaroid stored in the second material discharge box 33 reaches a certain amount, the clamping block 34 is removed, and the two sides of the second material discharge box 33 lose their fixation. Under the action of gravity, the second material discharge box 33 compresses the return spring 31 to descend, and after the second material discharge box 33 moves down and is parallel to the first material discharge box 28, the second cylinder 27 is started, and the movable rod of the second cylinder 27 is extended to push the first material discharge box 28 backward, so that the first material discharge box 28 pushes the second material discharge box 33 out, and the first material discharge box 28 replaces the position of the second material discharge box 33. At the same time, the concave plate 29 on the first material discharge box 28 is clamped into the second guide rod 32, realizing automatic box changing, thereby eliminating the need for manual intervention and reducing labor input.

[0033] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
