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 not consistent with 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

[0031] like figure 1As shown, the present embodiment provides a production method of a two-color pattern color steel plate, comprising the following steps: A. Prepare the steel strip to be printed, and in this step, use an uncoiler to uncoil the steel coil and perform edge trimming and stitching Machine stitches the uncoiled steel strip; B. Performs pretreatment on the steel strip to be printed; C. Uses the first roller coating unit to perform a roll coating transfer on the steel strip to be printed; D. Specific time Adopt the second roller coating unit to carry out secondary roller coating transfer to the steel strip; E. carry out post-treatment of spraying bright varnish to the steel strip; In the step C, adopt the servo control system to coat the first roller The unit is controlled, and the control process of the servo control system is, see image 3 :

[0032] S1, input the roll diameter and the process speed of each roller in the first roller coating unit into the PLC ...

Embodiment 2

[0045] 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 specif...

Abstract

The invention provides an improved production method of a multi-color patterned steel plate. On one hand, a PLC (programmable logic controller) control module in a servo control system is used for collecting the process speed and the rotating speed of every roller of a roller coating unit, calculating the theoretical linear speed of the surface of every roller in the roller coating unit and enabling the theoretical linear speeds of the roller surfaces to be identical to the process speed; and on the other hand, the actual linear speed of the surface of every roller in the rolling coating unit is collected by a servo control module with an encoder, a signal of the actual linear speed of the surface of every roller is input into the PLC control system, the actual linear speed of the surface of every roller is compared with the theoretical linear speed of the surface of every roller through the PLC control system, and the current frequency is adjusted until the actual linear speed of the surface of every roller is identical to the theoretical linear speed of the surface of every roller. By adopting the control method, the actual linear speed of the surface of every roller can be identical to the process speed, the stoppage is not needed in the production process for adjustment, and the production efficiency is improved.

Description

Technical field [0001] The invention involves a production method for color steel plates, which belongs to the field of color steel plate manufacturing. Background technique [0002] Color coating steel plates (commonly known as color steel plates) refer to the metal substrate before removing the surface grease, surface passivation and other surface coating, and then passed through the color coating printing machine to apply one on the surface to apply a one on the surfaceComposite materials formed after layer or multi -layer organic coatings. [0003] In order to coat the multi -color pattern, most coating production lines need to replace the color of the coating multiple times a day. In order to achieve the purpose of non -parking, no reduction in yield, and quickly replacing color, the coating head of the fine coating roller coating machine on the production line is generally in the production line.Two refined coating machines are installed in the location. The number one is t...
