A carton production line

Abstract

The invention discloses a carton production line which comprises a water-based printing machine and a carton pasting machine. A first conveying line and a second conveying line are arranged between the water-based printing machine and the carton pasting machine. A sheet overturning trolley for overturning carton boards on the first conveying line to the second conveying line is arranged between the first conveying line and the second conveying line. A jacking device corresponding to the sheet overturning trolley is further arranged at the tail end of the first conveying line. A lifting device for lifting the carton boards, a second alignment device for enabling the carton boards to be aligned and a pushing device for pushing the carton boards to the carton pasting machine are arranged at the tail end of the second conveying line. A pushing plate of the pushing device can be folded. By means of the carton production line, the aims of improving the carton quality and improving the production efficiency can be achieved, and the problems that due to the fact that manual board connection, manual board pushing, manual board aligning, manual board overturning and manual board pushing are needed after water-based printing is carried out on the carton boards, the labor intensity is large, the carton boards are out of order, and rejection products exist due to deviation of symmetrical folding lines are solved.

Description

technical field [0001] The invention relates to a production line for producing cartons, belonging to the field of printing machinery. Background technique [0002] When producing cartons, it is necessary to watermark the surface of the carton first, and glue the box after printing the pattern. Sticking box is mainly to fold the carton, glue, shape, dry and so on. Both watermark and glue box have realized mechanized automatic production. However, these devices are all independent, and the semi-finished cartons between each process need to be transported manually. After the watermarked cardboard is out of the machine, it is necessary to rely on people to catch the cardboard from the outlet of the watermarking machine, and then stack it and send it to the glue. Next to the machine. The watermarking machine prints on the top of the cardboard. When the cardboard comes out of the watermarking machine, the printing surface is facing up, and the printing surface is the outer sur...

Problems solved by technology

This kind of box gluer requires that the cartons must be pressed well along the "fold line" of the corrugation, otherwise the glued cartons may produce waste products. However, the current production equipment and manual transfer methods make it difficult for the carton boards to enter the box gluer. Guaranteed tidy
