Problems solved by technology

[0005] 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 of a control system for adjusting the speed, Therefore, it is impossible to correct errors when the patterns printed by adjacent roller coating units are misaligned

Embodiment 1

[0031] like figure 1 As shown, this embodiment provides a method for producing a two-color pattern color steel plate, which includes the following steps:

[0032] A. Prepare the steel strip to be printed. In this step, the uncoiler is used to uncoil the steel coil and trim the edge, and the uncoiled steel strip is stitched by a sewing machine;

[0033] B. Using the first roller coating unit to carry out a roller coating transfer to the steel strip to be printed;

[0034] C. After a certain period of time, the second roller coating unit is used to transfer the second roller coating to the steel strip.

[0035] In the step B, the servo control system is used to control the first roller coating unit, and the control process of the servo control system is, see image 3 :

[0036]S1, input the roll diameter and the process speed of each roller in the first roller coating unit into the PLC control module, and the PLC control module calculates the theoretical roll surface linear ...

Embodiment 2

[0049] In this embodiment, a structure of the roller coating transfer unit used in step B and step C in embodiment 1 is provided. For the specific structure, see figure 2 , the roller coating unit includes feeding equipment 1 for providing coating; suction roller 2, whose peripheral surface is connected with the feeding equipment 1, and has an image area formed when filling with the coating on the peripheral surface a plurality of depressions; the rubber coating roller 3, whose peripheral surface is connected with the suction roller 2, is used to accept the image area formed by the coating on the coating roller 3, and transfer the image area onto the steel plate; also includes a first scraper 4, installed on the first scraper bracket, contacting the suction roller 2 at a specific angle, for scraping off the paint outside the image area of ​​the suction roller 2 The second scraper 5, installed on the second scraper bracket, is in contact with the coating roller 2 at a specifi...

Abstract

The invention provides a production method of a multicolor pattern color steel plate. For the once transfer printing, on one hand, a PLC (programmable logic controller) control module in a servo control system is used for computing the theoretical roller surface linear velocity of each roller in a roll coater set by acquiring the technical velocity and the rotation velocity of each roller in the roll coater set, and enables the theoretical roll surface linear velocity to be accordant with the technical rotation velocity; and on the other hand, a servo control module with a coder acquires the practical roller surface linear velocity of each roller in the roll coater set, and inputs the practical roller surface linear velocity into the PLC control module, so that a PLC control system can be used for comparing the practical roller surface linear velocity with the theoretical roller surface linear velocity, and adjusting the current frequency till the practical roller surface linear velocity is accordant with the theoretical roller surface linear velocity. According to the control method, the practical roller surface linear velocity is adjusted to be accordant with the theoretical roller surface linear velocity, and the theoretical roller surface linear velocity is adjusted to be accordant with the technical velocity, so that the practical roller surface linear velocity is adjusted to be accordant with the technical velocity, and furthermore, the adjustment by stopping a production line does not need in the process of production, so that the production efficiency can be improved.

Description

technical field [0001] The invention relates to a production method for color steel plates with multi-color patterns, in particular to a production method for color steel plates with multi-color patterns, and belongs to the field of color steel plate 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] In order to apply multi-color patterns, most coating production lines need to change the color of the paint several times a day. Two finishing coaters are installed in the position, among which No. 1 is the upper single-head coating machine, and No. 2 is the double-sided coating machine. However, in the ...
