[0023] As a technical optimization solution of the utility model, a moving groove 15 for use with the stud 131 is opened on the right side of the movable frame 11 , and the stud 131 is located in the inner cavity of the moving groove 15 .

[0026] In this embodiment, the sliding frame 16 is provided to guide and support the rectangular plate 10 .

[0027] As a technical optimization solution of the utility model, a pin slot 17 is opened on the front of the movable plate 7, and a limiting bolt 18 is threadedly connected to the front of the positioning box 6. The back of the limiting bolt 18 penetrates the positioning box 6 and extends to the inner cavity of the pin slot 17.

[0031] As a technical optimization solution of the utility model, a guide plate 21 is fixedly connected to the top of the rectangular plate 10, and a guide groove 22 is opened at the top of the inner cavity of the concave plate 2 for use with the guide plate 21, and the outer surface of the guide plate 21 is slidably connected to the inner surface of the guide groove 22.

[0032] In this embodiment, the rectangular plate 10 can be guided and limited by providing the guide plate 21 and the guide groove 22 .

[0033] Working principle: When in use, the staff electrically connects the device to the mains. Then, when it is necessary to detect the surface flatness of pre-printed plate rollers of different specifications, the staff places the pre-printed plate roller in the inner cavity of the arc-shaped positioning groove 20 at the top of the support plates 19 on both sides. Then, the staff rotates and moves the limiting nut 132 so that the limiting nut 132 rotates and moves away from the movable frame 11 on the outer surface of the stud 131, thereby releasing the limit on the movable frame 11 and the rectangular plate 10. Then, the staff moves the movable frame 11 downward so that the movable frame 11 drives the universal ball 12 to fit tightly with the connection between the pre-printed plate roller. Then, the staff rotates and moves the limiting nut 132 in the opposite direction so that the limiting nut 132 rotates and moves on the outer surface of the stud 131 in the opposite direction so as to fit tightly with the connection between the movable frame 11, thereby completing the adjustment of the detection position of the universal ball 12.

[0034] Next, the staff member rotates and moves the limit bolt 18 so that the limit bolt 18 moves out of the inner cavity of the pin groove 17, thereby releasing the limit on the movable plate 7. Then, the staff member energizes the servo motor 4 plug and starts the external controller of the servo motor 4, so that the output end of the servo motor 4 drives the screw 3 to rotate on the inner surface thread of the rectangular block 5. At the same time, the rectangular block 5 drives the positioning box 6 to move, so that the positioning box 6 drives the rectangular plate 10, the movable frame 11 and the universal ball 12 to move, so that the universal ball 12 reciprocates on the top of the pre-printed plate roller. While the universal ball 12 rolls back and forth, the staff member can slowly rotate the pre-printed plate roller so that the universal ball 12 can perform all-round detection of the pre-printed plate roller. When a depression or a protrusion appears on the top of the pre-print roller, the universal ball 12 drives the movable frame 11, the rectangular plate 10 and the movable plate 7 to move downward or upward, so that the movable plate 7 drives the concave metal contact plate 8 to move upward or downward and contact the concave metal trigger plate 9, so that the concave metal contact plate 8 and the concave metal trigger plate 9 contact to energize the buzzer 14, so that the buzzer 14 buzzes to warn, so that the staff can promptly detect the concave or convex position on the surface of the pre-print roller, thereby realizing the detection of the flatness of the surface of the pre-print roller. The device is simple to operate and easy to use, so as to meet the customer's usage needs. At the same time, it avoids errors in detection and affects product quality.
