Bearings are fixedly installed on the cleaning plate, and the threaded rod and the cleaning plate are rotatably connected through the bearings.

[0007] Furthermore, to facilitate the installation of the drive assembly, a sliding groove is provided on the testing platform.

[0008] Furthermore, to facilitate the rotation of the first threaded shaft, the drive assembly includes a first threaded shaft and a second threaded shaft. Both the first threaded shaft and the second threaded shaft are rotatably mounted inside the slide groove. One end of the first threaded shaft is connected to the output end of the motor. Both the first threaded shaft and the second threaded shaft are threaded with sliders. The sliders are slidably engaged with the slide groove and are fixedly connected to the first slide rail.

[0009] Furthermore, in order to facilitate the linkage between the first threaded shaft and the second threaded shaft, a rotating gear is connected to one end of the first threaded shaft and the second threaded shaft, and a chain meshes between the rotating gears.

[0010] Furthermore, to facilitate adjustment of the position of the fixing plate, the adjustable fixing assembly includes a screw rod that is inserted into the testing table, and a fixing plate is connected between the screw rods.

[0020] The flatness detection device for flexible printing plates of this 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 this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figures 1-6 As shown, a device for detecting the flatness of flexible printing plates includes a detection table 1, on which a first slide rail 2 slides, and a mounting plate 3 connects the first slide rails 2. A second slide rail 4 is connected to the mounting plate 3, and an infrared rangefinder 5 is connected to the output end of the second slide rail 4. The longitudinal position of the infrared rangefinder 5 can be flexibly adjusted via the second slide rail 4 to measure the flatness of the longitudinal position of the flexible printing plate. A flattening roller 6 is installed on the lower surface of the mounting plate 3, located on one side of the second slide rail 4. The flattening roller 6 is adjusted to a suitable position via the first slide rail 2, thereby facilitating the cleaning and flattening of the flexible printing plate and improving the flatness of the infrared measurement. To ensure the accuracy of the detection data, an adjustable cleaning component 7 is connected to the mounting plate 3, and a driving component 8 that can drive the first slide rail 2 is connected to the detection table 1. Through the driving component 8 and the motor 10, the position of the first slide rail 2 can be flexibly adjusted, thereby flexibly adjusting the lateral position of the infrared rangefinder 5. One end of the detection table 1 is connected to the motor 10 for driving the driving component 8, and an adjustable fixing component 9 for fixing the flexible plate material is connected to the detection table 1. Through the adjustable fixing component 9, one end of the flexible plate material is fixed to prevent the flexible plate material from moving during flattening and cleaning, which would affect the flattening and cleaning effect.

[0022] The adjustable cleaning assembly 7 includes a threaded rod 701, which is threadedly connected to the mounting plate 3. A cleaning plate 702 is rotatably mounted on one end of the threaded rod 701. A handwheel 703 is fixedly mounted on the upper end of the threaded rod 701. Limiting rods 704 are connected to the cleaning plate 702 on both sides of the threaded rod 701. The limiting rods 704 are inserted into the mounting plate 3. A bearing 705 is fixedly mounted on the cleaning plate 702. The threaded rod 701 and the cleaning plate 702 are rotatably connected through the bearings 705. By turning the handwheel 703, the threaded shaft rotates, and the limiting rods 704 limit the position of the cleaning plate 702, thereby allowing the position of the cleaning plate 702 to be adjusted up and down. This facilitates the cleaning of the surface of the flexible plate and prevents impurities on the surface from affecting the accuracy of the test data.

[0023] The testing table 1 has a slide groove 11. The drive assembly 8 includes a first threaded shaft 801 and a second threaded shaft 802. Both the first threaded shaft 801 and the second threaded shaft 802 are rotatably installed inside the slide groove 11. One end of the first threaded shaft 801 is connected to the output end of the motor 10. A slider 803 is threadedly connected to both the first threaded shaft 801 and the second threaded shaft 802. The slider 803 is slidably engaged with the slide groove 11 and is fixedly connected to the first slide rail 2. One end of the first threaded shaft 801 and the second threaded shaft 802 is connected to a rotating gear 804. A chain 805 meshes between the rotating gears 804. When the motor 10 rotates, the first threaded shaft 801 rotates, and the rotating gear 804 rotates. Through the chain 805, the other rotating gear 804 rotates, and the second threaded shaft 802 rotates, thereby adjusting the position of the slider 803 and thus flexibly adjusting the lateral position of the infrared rangefinder 5 and the adjustable cleaning assembly 7.

[0024] The adjustable fixing component 9 includes a screw 901, which is inserted into the inspection table 1. A fixing plate 902 is connected between the screws 901 and the screws 901. The fixing plate 902 is located on the upper surface of the inspection table 1. A movable plate 903 is connected to the lower end of the screw 901. A nut 904 is threaded onto the screw 901. The nut 904 is pressed against the lower surface of the inspection table 1. By rotating the nut 904, the nut 904 can be adjusted to a suitable position. The fixing plate 902 can be moved to place one end of the flexible plate to be inspected under the fixing plate 902. By moving the fixing plate 902 and rotating the nut 904, the nut 904 is pressed against the lower surface of the inspection table 1, fixing the position of the fixing plate 902. This presses the flexible plate against the upper surface of the inspection table 1, thus preventing the flexible plate from moving during cleaning and flattening, which would affect the cleaning and flattening effect.
