[0020] When it is needed to install packing paper on the pay -off roll 3 of the pay -off mechanism for laser photoetching pattern packing paper printing device in actual use, the limiting of limiting component is removed first, then insertion block 6 is withdrawn from insertion slot 5 to separate pay -off support mounting cover 4 from the pay -off support 2 fixed on the top of lift support plate 1, and then the pivot fixed on both ends of pay -off roll 3 is removed from the top of pay -off support 2, the diameter of pay -off roll 3 is matched with the inner diameter of the roll of packing paper, the roll of packing paper is sleeved on the surface of pay -off roll 3, then the pivot of pay -off roll 3 is put back on the top of pay -off support 2, finally insertion block 6 is inserted back into insertion slot 5 and the limiting of limiting component is restored, so that pay -off support mounting cover 4 is mounted back on the top of pay -off support 2, and the installation of packing paper and pay -off roll 3 is completed, which saves time and effort and greatly improves the efficiency of the pay -off mechanism for laser photoetching pattern packing paper printing device.

[0021] Embodiment 2: On the basis of embodiment 1, in order to realize the operation of the limit assembly, the limit assembly includes: a limit rod mounting slot 7, a limit slot 8 and a limit rod 9. The limit rod mounting slot 7 is an "L"-shaped slot structure, and the limit slot 8 is a rectangular slot structure. The limit slot 8 is aligned with one end opening of the limit rod 9. One end of the limit rod 9 is movably inserted in the limit slot 8, and the other end of the limit rod 9 is movably inserted in one end opening of the limit rod mounting slot 7. The limit rod 9 is a rectangular rod structure, and a connecting plate movable slot 10 is provided at the bottom end of the unwinding bracket mounting cover 4. The connecting plate movable slot 10 is aligned with the other end opening of the limit rod mounting slot 7. One end of the connecting plate 11 is slidably connected to the connecting plate movable slot 10, and the other end of the connecting plate 11 is slidably connected to the limit rod mounting slot 7, and the limit rod 9 is away from the limit One end of the slot 8 is fixed to the connecting plate 11, and a push-pull rod hole 12 is provided on the surface of the unwinding bracket mounting cover 4. The push-pull rod hole 12 is connected to the movable slot 10 of the connecting plate, and one end of the push-pull rod 13 is movably inserted in the push-pull rod hole 12. One end of the push-pull rod 13 is inserted in the push-pull rod hole 12 and is fixed to the connecting plate 11, and the other end of the push-pull rod 13 extends out from the push-pull rod hole 12, and a spring slot 14 is provided on the hole wall of the push-pull rod hole 12. The spring slot 14 has a circular groove structure, and the spring slot 14 is opened along the push-pull rod hole 12 for a week. A spring plate 15 is slidably connected to the spring slot 14, and the spring plate 15 has a circular plate structure. The inner ring of the spring plate 15 is fixed on the surface of the push-pull rod 13, and a spring 16 is fixed to one end of the spring plate 15, and the other end of the spring 16 is fixed to the inner wall of the groove body of the spring slot 14.

[0022] When the limit assembly needs to contact the limit, the push-pull rod 13 is pushed to the depth of the push-pull rod hole 12. On the one hand, the movement of the push-pull rod 13 drives the spring plate 15 to move in the spring groove 14 in the direction close to the connecting plate movable groove 10, thereby compressing the spring 16. On the other hand, the movement of the push-pull rod 13 pushes the connecting plate 11 in the connecting plate movable groove 10 to move in the direction away from the limit groove 8, and the connecting plate 11 drives the limit rod 9 to move in the same direction, so that the limit rod 9 withdraws from the limit groove 8 and is completely retracted into the limit rod installation groove 7, thereby releasing the limit of the limit assembly, and then pulling the unwinding bracket mounting cover 4 upwards can make the plug-in block 6 withdraw from the plug-in groove 5, completing the disassembly of the unwinding bracket mounting cover 4 and the unwinding bracket 2; when it is necessary to restore the limit, the push-pull rod 13 is pushed to the push-pull rod hole 12 again. Push deeply, so that the spring 16 is compressed and the limit rod 9 is completely retracted into the limit rod mounting groove 7, and then the plug-in block 6 is inserted into the plug-in groove 5. After insertion, the limit groove 8 is aligned with the opening of one end of the limit rod mounting groove 7 again, and then the push-pull rod 13 is released, and the compressed spring 16 pushes the spring plate 15 in the direction away from the connecting plate movable groove 10. The spring plate 15 drives the push-pull rod 13 to move in the same direction, and the push-pull rod 13 pulls the connecting plate 11 in the direction close to the limit groove 8. The movement of the connecting plate 11 pushes one end of the limit rod 9 into the limit groove 8 again, and the other end of the limit rod 9 stays in the limit rod mounting groove 7, which makes the plug-in block 6 unable to withdraw from the plug-in groove 5, that is, the limit mechanism restores the limit of the plug-in groove 5 on the plug-in block 6, completing the installation of the unwinding bracket mounting cover 4 and the unwinding bracket 2.

[0023] After the paper is rolled up and down, the paper is put on the unwinding roller 3, and the rotating shaft of the unwinding roller 3 is put back on the top of the unwinding bracket 2, and the plug block 6 is finally put into the unwinding bracket 2. When the cam 14 is in the closed position, the cam 14 is in the closed position, and the cam 14 is in the closed position, so that the cam 14 can move in the closed position, thereby the cam 14 is in the closed position, and the cam 14 is in the closed position, so that the cam 14 can move in the closed position, thereby the cam 14 is in the closed position, and the cam 14 is in the closed position, so that the cam 14 can move in the closed position, thereby the cam 14 is in the closed position, and the cam 14 is in the closed position, When the cam 11 is in the closed position, the spring 16 is pulled back to the left and the spring 16 is pulled out of the closed position, so that the cam 11 can slide back and forth, and the spring 16 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, so that the cam 11 can slide back and forth, Then, the push-pull rod 13 is aligned with the opening at one end of the limit rod mounting groove 7, and then the push-pull rod 13 is released. The compressed spring 16 pushes the spring plate 15 in the direction away from the connecting plate movable groove 10, and the spring plate 15 drives the push-pull rod 13 to move in the same direction. The push-pull rod 13 pulls the connecting plate 11 in the direction close to the limit groove 8. The movement of the connecting plate 11 pushes one end of the limit rod 9 back into the limit groove 8, and the other end of the limit rod 9 stays in the limit rod mounting groove 7, which makes the plug-in block 6 unable to withdraw from the plug-in slot 5, that is, the limit mechanism restores the limit of the plug-in slot 5 on the plug-in block 6, completing the installation of the unwinding bracket mounting cover 4 and the unwinding bracket 2.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
