Problems solved by technology

The above-mentioned color steel plate production line has the following problems: continuous operation cannot be performed during the entire production process, and the intermediate transportation link is complicated, resulting in low production efficiency
[0008] However, the applicant found in the process of using the above-mentioned gravure printing machine that the surface speed of the coating roller and the suction roller is often different from the process speed of the entire production line Inconsistency, and the entire production line lacks a control system for online adjustment of the rotational speed of the suction roller and the coating roller, resulting in frequent stoppage adjustments after the entire production line has been running for a period of time, thus affecting the efficiency of the entire production line; and If the adjustment is not stopped, the speed of conveying the steel strip will be inconsistent with the surface speed of each roller, which often leads to the inability to transfer the steel strip according to the predetermined position; in addition, in order to print multi-color patterns, it is often necessary Several groups of roller coating units work together, but the above-mentioned gravure printing machine in the prior art lacks a control system that enables continuous production of adjacent roller coating units, that is, the staff needs to observe whether the first roller coating unit has been One color coating is completed, and after the coating is confirmed, the adjacent roller coating units are manually started, so that continuous production cannot be achieved between adjacent roller coating units; at the same time, due to the lack The control system that adjusts the rotation speed, so that it is impossible to correct the error when the pattern printed by the adjacent roller coating unit is misaligned

Embodiment 1

[0035] like Figure 4 As shown, the present embodiment provides a production line for roll-coated color steel plates ( figure 1 It is a flow chart of color steel plate production using the production line provided in this embodiment), including the following equipment: uncoiler 1, used to uncoil the crimped steel strip, and trim the steel strip; sewing machine 2, used to The front and rear steel strips after uncoiling 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 stitched by the sewing machine 2 run smoothly; the entrance looper 4. It is 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 of the inlet looper 4 run smoothly; The machine 6 is used for corona treatment of the steel strip; the third tension roller ...

Embodiment 2

[0043] like figure 2 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 off the rubber coa...

Embodiment 3

[0048] This embodiment provides a kind of servo control system for the roller coating color steel plate production line in embodiment 1, comprises, PLC control module, and described 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, the PLC control module also has a calculator, and the calculator is used to calculate the theoretical roll surface line speed of each roll according to the process speed and the roll diameter of each roll (the specific calculation method is: theoretical speed = process speed / W*roller diameter), theoretical roll surface speed=theoretical rotating speed*roller diameter*W), so that the theoretical roll surface speed of each roll is consistent with the process speed, and the calculated theoretical roll surface line of each roll The speed signals are respectively output, and the PLC control module also includes a comparator; the servo control module has an ...

Abstract

The production line of the multi-color pattern color steel plate provided by the present invention, on the one hand, the PLC control module in the servo control system calculates the theoretical roll surface line of each roller in the roller coating unit by collecting the process speed and the rotating speed of each roller in the roller coating unit speed, and make the theoretical roller surface speed consistent with the process speed; on the other hand, the actual roller surface speed of each roller in the roller coating unit is collected through the servo control module with an encoder, and the actual roller surface speed signal is input to the PLC control system, so that the PLC control system can compare the actual roll surface speed with the theoretical roll surface speed, and adjust the current frequency until the actual roll surface speed is consistent with the theoretical roll surface speed. The above control method ensures that the actual roll surface line speed is consistent with the process speed, and then there is no need to stop the line for adjustment during the production process, which improves the production efficiency. Moreover, in the production method provided by the present invention, in order to improve the adhesion between the paint and the surface of the steel strip and the formability of the steel strip after printing, the steel strip is subjected to pre-transfer treatment.

Description

technical field [0001] The invention relates to a multi-color pattern roller-coated color steel plate production line, which belongs to the field of color steel plate production and manufacturing. Background technique [0002] Color-coated steel plate (commonly known as color-coated steel plate) refers to the metal base material that is firstly degreased by the continuous unit and subjected to surface passivation and other pre-coating treatments, and then passes through a color-coated printing machine to coat the surface with a Composite material formed after one or more layers of organic paint. [0003] Cold-rolled sheets and hot-rolled sheets are mainly used as raw materials in the existing domestic color steel production. The traditional color steel plate production is divided into three production lines: firstly, use a transverse cutting line to uncoil and level, cut the steel plate to the required length, and then stack the steel plates to the required height; then use...
