Implementation

[0028] Reference Figures 1 to 3 The embodiments of the present invention will be further described below.

[0029] Specifically, this embodiment includes a frame 1, a storage plate 2, and a detection unit.

[0030] The frame 1 has a testing station 11 on its worktable. The testing station 11 has a cavity 10 on its worktable. An electric push rod 3 is provided at the bottom of the cavity 10. The output end of the electric push rod 3 is connected to a top plate 31). The top plate 31) is used to abut against the bottom of the storage plate 2.

[0031] The storage plate 2 has a work station slot 20 for placing the flexible plate on its end face. The storage plate 2 is movably connected to the inspection station 11. The storage plate 2 has several positioning holes 20. The inspection station 11 has a rod that passes through the positioning holes 20. One end of the rod 200 has a limiting end. The rod 200 ensures the stability of the storage plate 2 when it is lifted up.

[0032] The detection unit includes an imprinting component and an inking component.

[0033] The inking assembly is placed on the inspection station 11 and is used to apply ink to the end face of the flexographic plate.

[0034] The printing assembly includes a printing plate 4 for printing from an ink-coated flexographic plate, a laser scanner 5 for scanning the printing plate 4, a stand 13, and a power unit.

[0035] The power unit includes an electric lifting rod 61, a turntable 62, and a motor 63.

[0036] The laser scanner 5 is placed on the table of the stand 13.

[0037] The bottom end of the electric lifting rod 61 is connected to a rotating shaft. A bearing is pre-embedded in the center of the turntable 62. The rotating shaft is connected to the bearing on the turntable 62. The output end of the motor 63 is connected to a driving gear. A driven gear is provided on the outer peripheral wall of the rotating shaft. The driving gear and the driven gear mesh. When the rotating shaft is driven to rotate by the motor 63, it rotates the electric lifting rod 61. At the same time, the printing plate 4 on the electric lifting rod 61 can rotate 360°. This enables the printing plate 4 to rotate between the platform 13 and the inspection station 11.

[0038] A printing element 41 is connected to the end face of the printing plate 4. The printing element 41 includes a cloth body 411 and a frame 412. The periphery of the cloth body 411 is fixed to the frame 412. The frame 412 has connecting holes. The printing plate 4 has a slot 40 for inserting the frame 412. The slot 40 has holes communicating with the connecting holes. The connecting holes and holes are connected by screws to achieve installation. The end face of the printing plate 4 has a protrusion 413 that abuts against the rear end face of the cloth body 411. This protrusion is used to spread the cloth body 411 open, ensuring that the end face of the cloth body 411 is flat, thereby ensuring the quality of the finished product when printing with flexographic plates.

[0039] A dryer 7 is also installed on the rotation path of the slide plate 4. The dryer 7 is located outside the frame 13, and the air outlet of the dryer 7 is below the moving path of the slide plate 4.

[0040] The ink application assembly includes a bracket 8, a roller 82, a guide rod 83, and a second motor 84. The output end of the second motor 84 is connected to a lead screw assembly 85, which is a ball screw slide module, including a lead screw and a slide that is movably connected to the lead screw. When the second motor 84 drives the lead screw to rotate, the slide will move on the lead screw.

[0041] One side of the bracket 8 is movably connected to the lead screw assembly, and the other side is slidably connected to the guide rod 83. The end of the roller 82 has a shaft, and there is a bearing on the bracket 8 for the shaft to connect. When the roller 82 contacts the flexographic plate, the bracket 8 is displaced by the motor 84, and the ink on the roller 82 will be brushed onto the flexographic plate. In order to ensure the strength and uniformity of the ink coating on the flexographic plate, when the electric push rod 3 on the detection station 11 pushes the storage plate 2 upward, the flexographic plate will be squeezed against the roller 82.

[0042] A brush sleeve for absorbing ink is fitted on the roller 82. The brush sleeve can be made of sponge. A box 9 is installed on the bracket 8. The box 9 stores ink. Several ink injection tubes 91 for dispensing ink are connected to the box 9. The ink injection tubes 91 are above the brush sleeve. The ink in the box 9 is dripped onto the brush sleeve through the ink injection tubes 91. The box 9 has an opening for easy pouring of ink.

[0043] Working principle:

[0044] The flexographic plate is placed on the storage plate 2. The roller 82 with ink is controlled to move and press against the flexographic plate, applying ink to the flexographic plate. After inking is completed, the printing plate 4 with the printing element 41 is controlled to rotate above the detection station 11. The printing plate 4 descends, and the cloth 411 on the printing element 41 presses against the flexographic plate, transferring the information on the flexographic plate onto the cloth 411. The printing plate 4 is then controlled to rotate above the dryer 7, where the information on the cloth 411 is quickly dried. The printing plate 4 is then reset above the stand 13 with the laser scanner 5. The laser scanner 5 scans the cloth 411 and transmits the information to the computer. Finally, the comparison information on the computer is used to obtain the detection result of the flexographic plate.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
