Drying delivery production line structure for lithographed sheet

Abstract

The invention relates to a drying delivery production line structure for a lithographed sheet. The drying delivery production line structure comprises a support, two beams which are parallel are erected on the support; a circulating conveying chain is arranged between the beams; a drying oven is arranged below the circulating conveying chain; fixed frames are fixedly arranged outside the beams; ultraviolet sensors are arranged on the fixed frames respectively; the ultraviolet sensors face the lithographed sheet on the circulating conveying chain; lithographed sheet push plates which face the circulating conveying chain are also arranged on the fixed frames and are driven by a cylinder piston rod; the ultraviolet sensors transfer a signal to a controller to control the driving of a cylinder; the discharge end of the circulating conveying chain is provided with a discharge table which is matched with the circulating conveying chain; baffles are arranged on two sides of the discharge table respectively; a rotating shaft is erected above the discharge table; a buffer plate is arranged on the rotating shaft; air vents are distributed in the buffer plate; and a plurality of chains are also arranged on the rotating shaft. By the drying delivery production line structure, the lithographed sheet is prevented from being mismatched in a drying production line, the labor intensity is low in the process, time and labor are saved, the work efficiency is improved, and the quality of the lithographed sheet is ensured during material receiving.

Description

technical field [0001] The present invention relates to the field of iron printing production, in particular to a structure of iron printing drying and conveying production line. Background technique [0002] In the production process of iron packaging boxes, it must first go through the iron printing process, and the iron printing is to print patterns on tinplate (tin plate). It mainly uses the physical properties of water and ink to repel each other, and with the help of printing pressure, the graphic on the printing plate is transferred to the tinplate through the blanket, which belongs to the principle of lithographic offset printing. Moreover, when printing patterns of different colors, it is necessary to print one color and one color. After printing one color, it needs to be dried and then enter the printing of the next color, so the drying device is particularly important. The existing drying and conveying production line has a simple structure, and the iron printing...

Problems solved by technology

[0004] The purpose of the present invention is to make up for the deficiencies of the existing technology, and to provide a structure of a drying and conveying production line for iron printing, which solves the problem of the simple structure of the existing drying and conveying production line. , The iron printing will be dislocated during the transportation process, which requires manual adjustment. The labor intensity is high, time-consuming and labor-intensive, and the work efficiency is low. When the material is collected, the end of the printed iron is easy to collide with the iron buffer plate, and the edge is uneven. Affect the quality of the next step of processing, high scrap rate and other issues
