Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper cup printing technology, specifically a multi-color alignment and positioning mechanism for paper cup printing. Background Technology
[0002] A multi-color registration and positioning mechanism is a special device used in the paper cup printing process to ensure the precise alignment of multiple color printing plates. It corrects the positional deviation of different color layers in real time through a fine-tuning system to prevent problems such as blurry patterns, misaligned colors, or edge ghosting caused by registration errors.
[0003] In the process of printing on paper cups, by setting up a CCD camera and a PLC controller to work together to scan the printing color mark points in real time, the paper cups can be printed accurately. However, the existing CCD cameras are still exposed after use, which makes it easy for dust to adhere to the CCD camera lens, affecting the subsequent scanning effect and reducing the accuracy of subsequent printing on paper cups.
[0004] Therefore, we propose a multi-color alignment and positioning mechanism for paper cup printing to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Please see Figure 1-6A multi-color registration and positioning mechanism for paper cup printing includes a processing table 1. Several pad printing machine bodies 3 are arranged on the top of the processing table 1. A load-bearing plate 4 is fixedly installed on the front side of each pad printing machine body 3. A CCD camera body 5 is fixedly installed on the bottom of each load-bearing plate 4. A PLC controller 2 is installed on the top of the processing table 1 near one side. (The pad printing machine body 3, CCD camera body 5 and PLC controller 2 are all existing technologies. By setting multiple pad printing machine bodies 3, multi-color printing of paper cups can be performed. With the cooperation of CCD camera body 5 and PLC controller 2, positioning can be achieved before printing.) A placement plate 6 is arranged on the top of the processing table 1 near the middle position. A limit component 8 is arranged in the inner cavity of the placement plate 6. A protective component 7 is arranged on the outer periphery of each CCD camera body 5.
[0026] The protective component 7 includes an L-shaped frame 71 fixedly installed at the bottom of the load-bearing plate 4 near both sides. The opposite sides of the L-shaped frame 71 are rotatably connected to a first threaded rod 72. (The outer periphery of the first threaded rod 72 has opposite external threads near both ends, and the thread precision is the same. When the first threaded rod 72 rotates, the two threaded sleeves 76 can move the same distance on the outer periphery of the first threaded rod 72.) The outer periphery of the first threaded rod 72 is threadedly connected to a threaded sleeve 76 near the middle position. The front side of the threaded sleeve 76 is fixedly installed with a protective cover 77. The outer periphery of the first threaded rod 72 is fixedly sleeved with a worm gear 73 near the other end, and the rear side of the worm gear 73 is engaged with a worm 74. A servo motor 75 is fixedly installed at the top of the inner cavity of one side of the L-shaped frame 71, and the power output shaft of the servo motor 75 is fixedly connected to the worm 74.
[0027] Specifically, when the CCD camera body 5 is in use, with the cooperation of the protective component 7, the rotation of the first threaded rod 72 allows the threaded sleeve 76, which is threaded to the outer periphery of the first threaded rod 72, to move to the opposite side. This allows the protective cover 77, which is fixed on the threaded sleeve 76, to move to the opposite side, thereby covering the CCD camera body 5. This prevents dust or other impurities from adhering to the outer periphery of the CCD camera body 5 when it is not in use, thus affecting its scanning accuracy and improving the subsequent paper cup printing effect.
[0028] A rectangular block 761 is fixedly installed on the rear side of the threaded sleeve 76, and a round rod 762 is movably passed through the opposite side of the rectangular block 761, and the two ends of the round rod 762 are fixedly connected to the L-shaped frame 71 respectively.
[0029] Specifically, by setting rectangular block 761 and round rod 762, the movement of threaded sleeve 76 can be limited, thereby improving the smoothness of its movement.
[0030] The bottom of the placement plate 6 is provided with a movable seat 61. The top of the movable seat 61 is fixedly installed with a first electric slide rail 62 near both sides. The outer periphery of the first electric slide rail 62 is slidably connected with a first electric slider 63, and the top of the first electric slider 63 is fixedly connected to the placement plate 6. The top of the processing table 1 is fixedly installed with two second electric slide rails 64 near the front side. The outer periphery of the second electric slide rail 64 is slidably connected with a second electric slider 65, and the top of the second electric slider 65 is fixedly connected to the movable seat 61.
[0031] Specifically, the PLC controller 2 can control the movable seat 61 to move to the sides or back and forth.
[0032] Example 2
[0033] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2 and Figure 3 The limiting component 8 includes a support frame 81 fixedly installed on the front side of the placement plate 6 near both sides. A threaded tube 83 is movably inserted through the front side of each support frame 81. A knob 82 is fixedly installed at the front end of each threaded tube 83. A second threaded rod 85 is threadedly connected to the inner cavity of each threaded tube 83. A movable plate 86 is fixedly installed at the rear end of each second threaded rod 85. The opposite side of each movable plate 86 is slidably connected to the inner cavity sidewall of the placement plate 6. A drive rod 87 is movably inserted through the opposite side of each movable plate 86. A movable block 84 is fixedly installed at the bottom end of each drive rod 87.
[0034] Specifically, during paper cup printing, with the cooperation of the limiting component 8, when the moving plate 86 moves forward, the driving rod 87, which is movably inserted into the inner cavity of the inclined groove 861, can cause the moving block 84 to move downward, thereby fixing the paper cup blank and preventing the blank from moving during printing, thus preventing ghosting during subsequent printing.
[0035] Several protrusions 841 are fixedly installed on the bottom of the movable block 84. Limiting telescopic rods 842 are fixedly installed on the top of the movable block 84 near the front and rear sides. Connecting blocks 843 are fixedly installed on the top of the limiting telescopic rods 842. The connecting blocks 843 are fixedly connected to the placement plate 6. Several protrusions 841 are evenly distributed on the bottom of the movable block 84. The protrusions 841 are all made of rubber.
[0036] Specifically, by setting a limiting telescopic rod 842, the movement of the movable block 84 can be limited, thereby improving its movement stability, and by setting several protrusions 841, the paper cup blank paper can be fixed and stabilized.
[0037] Each of the opposite sides of the movable plate 86 is provided with a slanted groove 861, and the opposite ends of the drive rod 87 are respectively movably inserted into the inner cavity of the adjacent slanted groove 861.
[0038] Specifically, by setting the inclined groove 861, when the moving plate 86 moves, the drive rod 87 can move up or down, which is conducive to adjusting the position of the movable block 84.
[0039] Working Principle: In use, the paper cup preform is first placed on top of the placement plate 6. Then, rotating two knobs 82 rotates the threaded tube 83 fixed to the knobs 82. This causes the second threaded rod 85, threaded into the inner cavity of the threaded tube 83, to pull the moving plate 86 forward. With the cooperation of the inclined groove 861, the moving block 84 moves downward under the limitation of the two limiting telescopic rods 842 via the drive rod 87, thus limiting the paper cup preform and preventing movement during printing, thereby avoiding ghosting in subsequent printing. The PLC controller 2, pad printing machine body 3, load-bearing plate 4, and CCD camera body 5 can position the preform placed in the inner cavity of the placement plate 6 for multi-color printing. When the CCD camera body 5 is not needed, it is... PLC controller 2 starts servo motor 75. The rotation of the power output shaft of servo motor 75 drives the worm gear 74 fixed to the end of the power output shaft of servo motor 75 to rotate, which in turn causes the worm wheel 73 meshing with the worm gear 74 to rotate, which in turn causes the first threaded rod 72 to rotate. The outer periphery of the first threaded rod 72 has opposite external threads near its two ends. This allows the threaded sleeve 76, which is threaded to the outer periphery of the first threaded rod 72, to move to the opposite side under the limitation of rectangular block 761 and round rod 762. This allows the protective cover 77 fixed on the threaded sleeve 76 to be located on the outer periphery of CCD camera body 5, which can protect CCD camera body 5 and prevent dust or other impurities from adhering to the outer periphery of CCD camera body 5 when not in use, thus affecting its scanning accuracy and improving the subsequent paper cup printing effect.
