Corrugated paper indentation device for producing packaging box

Abstract

The invention discloses a corrugated paper indentation device for producing a packaging box. The corrugated paper indentation device comprises a workbench. Fixing frames are symmetrically and fixedlyconnected to the two sides of the upper end of the workbench. Horizontal movement grooves are formed in one sides of the inner walls of the fixing frames. A walking frame is connected between the twohorizontal movement grooves in a sliding manner. A movable shaft is inserted and connected in each movable groove, wherein the outer wall of the movable shaft is in threaded connection with an annularclamping block, one side of the upper end of the annular clamping block is in engaged connection with a bevel gear, and a connecting rod is connected between the two bevel gears. The outer wall of the middle portion of the connecting rod is in cup joint with a first gear, the upper end of the first gear is in engaged connection with a second gear, a fixing block is arranged at the lower end of each movable shaft, the lower end of each fixing block is provided with a downward pressing wheel through a rotation groove, and a cross rod is horizontally inserted and connected in each downward pressing wheel. The corrugated paper indentation device is simple in structure and easy to operate, losses generated during indentation can be effectively reduced, meanwhile, friction force is reduced, theindentation effect is improved, and the device is convenient and ingenuous to use and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of production packaging, in particular to a corrugated paper creasing device for producing packaging boxes. Background technique [0002] Before the corrugated box is formed, it is necessary to roll the corrugated cardboard through the creasing machine to form the indentation score line, and then use the folding equipment to fold and form the indentation score line. The corrugated cardboard is generally composed of upper and lower flat paper and corrugated paper sandwiched between the upper and lower flat paper. During the creasing process of corrugated cardboard, it is easy to crack at the position of the creasing score line when it is folded due to its own hardness and brittleness. The resulting defective products not only affect the production efficiency, but also greatly increase the production cost of the enterprise. In order to solve the problem of cracking at the position of the indentation line, ma...

AI Technical Summary

Problems solved by technology

When spraying water, if the amount of water added is too large, it is easier to cause damage to the corrugated cardboard during the creasing process, and if the amount of water added is insufficient, the effect will not be achieved. It is extremely difficult to control the amount of water sprayed properly.

Moreover, the water sprayed on the cardboard is generally in the form of dots, and the uniformity is not good, so it is still difficult to prevent the problem of cracking at the position of the indentation line
