Sandwich-free double corrugated board synchronous paper feeding device and method

Abstract

The invention discloses a sandwich-free double corrugated board synchronous paper feeding device and method. The device comprises a mounting plate, an upper tooth face shaft, a lower tooth face shaft, an upper synchronous belt wheel, a lower synchronous belt wheel, a double-face tooth synchronous belt and a synchronous belt guide wheel, the upper tooth face shaft and the lower tooth face shaft are arranged in parallel, and the two ends of the upper tooth face shaft and the two ends of the lower tooth face shaft are rotationally mounted on the mounting plate; and the upper synchronous belt wheel is fixedly installed at one end of the upper tooth face shaft, the lower synchronous belt wheel is fixedly installed at one end of the lower tooth face shaft, and the inner tooth surface and the outer tooth surface of the double-face tooth synchronous belt are in meshing transmission with the upper synchronous belt wheel and the lower synchronous belt wheel respectively. The synchronous belt guide wheel is rotationally mounted at the outer side of the mounting plate. According to the sandwich-free double corrugated board synchronous paper feeding device and method, the corrugated tip of upper-layer single corrugated paper faces downwards and is matched with a tooth groove of the upper tooth face shaft, the corrugated tip of lower-layer single corrugated paper faces upwards and is matched with a tooth groove of the lower tooth face shaft, the upper tooth face shaft and the lower tooth face shaft rotate oppositely, and therefore the upper-layer single corrugated paper and the lower-layer single corrugated paper are synchronous; and tip-to-tip entering into the next process is ensured.

Description

technical field [0001] The invention relates to the technical field of carton production equipment, and more specifically relates to a device and method for synchronous paper feeding of double corrugated cardboard without sandwich. Background technique [0002] The main raw materials of cardboard are wood pulp and waste paper. Since 2021, the Ministry of Environmental Protection has issued a policy of prohibiting the import of waste paper, and trees cannot be mined at will. The shortage of domestic papermaking materials is obvious to all. [0003] At present, most of the double-corrugated boards in the prior art are double-corrugated paper layers sandwiched between the face paper layer and the inner paper layer, and a sandwich core is arranged between the double-layer corrugated paper layers, and the two sides of the sandwich core are respectively bonded to the corresponding corrugated paper. Together, the sides of the two layers of corrugated paper away from the core are re...

Problems solved by technology

However, in the production process of non-sandwich double corrugated cardboard, the pit diameters of the corrugated layers of the upper and lower two-layer single tiles are the same, and the point-to-point needs to be fixedly connected to each other. However, during the production process, the flute points of the upper and lower single-layer single Unable to correspond synchronously, affecting production efficiency
