Embodiment 1
[0038] Such as figure 1 As shown, the present embodiment provides a production line for roll-coated color steel plates, including the following equipment: uncoiler 1, used to uncoil the crimped steel strip, and trim the steel strip; sewing machine 2, used to be described The front and rear steel strips of the uncoiler 1 are connected together to ensure the continuity of the process after replacing the steel coils; the first tension roller 3 is used to make the steel strips sewn by the sewing machine 2 run smoothly; the entrance looper 4 , used to ensure that the process section does not stop when the uncoiler 1 is uncoiled and the sewing machine 2 is stitched; the second tension roller 5 is used to make the steel strip wound out from the inlet looper 4 run smoothly; the corona machine 6, used for corona treatment of the steel strip; the third tension roller 7, used for smooth running of the corona treated steel strip; roller coating equipment assembly 8, used for roller coatin...
Embodiment 2
[0046] Such as figure 2 and image 3 As shown, the present embodiment provides a roll coating device assembly 8 used in Embodiment 1, including a feeding device 81 for providing coating; a suction roller 82, whose peripheral surface is connected with the feeding device 81, The peripheral surface has a plurality of depressions that form image areas when filled with the paint; the rubber coating roller 83, whose peripheral surface is connected with the suction roller 82, is used to accept the paint in the coating process. The image area formed on the roller 83, and transfer the image area to the steel plate; the first scraper 84, installed on the first scraper bracket, contacts with the suction roller 82 at a specific angle, and is used to scrape off the image area. the paint outside the image area of the suction roller 82; and the second scraper 85, installed on the second scraper bracket, is in contact with the coating roller 82 at a specific angle, and is used to scrape o...
Embodiment 3
[0051] This embodiment provides a kind of servo control system for the roller coating color steel plate production line in embodiment 1, and described servo control system comprises: PLC control module, has collector, is used for collecting the roller of each roller of the first roller coating unit Diameter and process speed data, and also has a calculator, which is used to calculate the theoretical roll surface speed of each roll according to the process speed and the roll diameter of each roll, so that the theoretical roll surface speed of each roll is consistent with the process speed, and The calculated theoretical roller surface linear velocity signals of each roller are respectively output, and a comparator is also provided; the servo control module has an encoder, and the servo control module receives the theoretical roller surface linear velocity of each roller from the PLC control module signal, and drive each roller according to the theoretical roller surface speed si...
