Description

A corrugated cardboard production line

technical field

The invention belongs to the field of corrugated packaging machinery manufacturing, and more specifically relates to a group of corrugated base papers that are preheated, glued, corrugated, double glued, pressed, and dried to form corrugated cardboard, and then longitudinally cut. , cross-cutting, stacking, and output equipment, specifically a corrugated cardboard production line.

Background technique

The corrugated cardboard production equipment in the prior art is shown in Figure 1, and mainly includes a paper splicer 7, a base paper frame 8, a corrugator 9, a preheating cylinder 10, a gluing machine 17, a double-facer 18, and a slitting machine 19. , cross-cutting machine 20 and stacking machine 21, each piece of equipment is arranged sequentially according to the order from left to right, forming an integral corrugated cardboard production line, but because it involves more single equipment, only a five-layer corrugated cardboard production line The length of the corrugated cardboard is as high as 90-100 meters, the production line is longer, and the production workshop takes up a lot of space; the specific process of producing corrugated cardboard is shown in Figure 1. After passing through the paper splicer 7 and the original paper rack 8, they respectively enter the preheating cylinder 10 for preheating and tempering. After the preheating and tempering are completed, the corrugated medium paper enters the corrugating machine 9, and the corrugating machine 9 can be set according to the requirements. There are multiple corrugated core papers, which are heated by the corrugating rollers in the corrugating machine 9 and pressed together to form a corrugated shape. After being glued, they are laminated with cardboard paper to form single-sided corrugated cardboard. The single-sided corrugated cardboard is carried out on the bridge conveyor Accumulation, sorting, enter the preheating cylinder again for preheating, and then enter the gluing machine 17 for secondary gluing. At the same time, the facial tissue is conveyed through the facial tissue reel set under the corrugated cardboard, and is preheated after reaching the facial tissue preheating cylinder. Heat, the preheated face paper is output from the bottom of the corrugated cardboard. At this time, the single-sided corrugated cardboard coated with glue and the preheated face paper enter the double-facer 18 in the way of setting up and down for heating, bonding and drying. Dry to form corrugated cardboard. After the corrugated cardboard is slit by the slitting machine 19, it enters the cross-cutting machine 20 and is cut into sheet-shaped corrugated cardboard, which is output after sorting and stacking. In the heating part of the double-facer 18 in this production line, since the direction of the face paper is downward when laminating the single-faced corrugated cardboard, the pre-printed surface of the face paper will directly contact and be opposite to the high-temperature surface of the heating plate of the double-facer 18. Sliding, the working temperature of the surface is 150℃～180℃, which is easy to cause damage to the pre-printed surface of the facial paper, and puts forward higher requirements for the printing surface of the facial paper, and if the temperature is too high at this time, it is necessary to reduce the temperature accordingly and adjust the entire surface. The running speed of the production line results in an increase in cost and a decrease in production efficiency. In addition, the corrugated cardboard production line can hardly produce the pre-printed and laminated face paper.
