Secondary impression device of corrugated case

Abstract

The invention discloses a secondary indentation device for corrugated cases and belongs to the technical filed of corrugated case manufacturing equipment. The secondary indentation device comprises a paper conveying mechanism which is matched with an indentation mechanism and adopts a paper conveying structure driven by two synchronous small belts and a hexagonal steel type transmission shaft, a transversely positioning and arranging mechanism of the corrugated cardboards and a worm-and-gear indentation wheel pressure adjusting mechanism, wherein each synchronous small belt (1) is corresponding to a pair of a driving roller (2) and a driven roller (3) which are matched and arranged on a piece of wall plate (17), a hexagonal steel type rotating shaft (19) and a driven hexagonal steel type rotating shaft (20) which are arranged on a large wall plate (23) of a machine frame, and a threaded rod shaft driving the small wall plate (17) to adjust the axial positions of the rollers for standard and continuous paper conveying. One side of the transversely positioning mechanism has a plate type fixed compass (40) and the other side of the transversely positioning mechanism has a plate type elastic compass which is capable of carrying out micro limit adjustment freely and automatically. The transversely positioning device is arranged on a wall plate through a length bolt (55) at a position which can be adjusted. A pressure adjusting mechanism of an indentation wheel is of one-side worm-and-gear type. The axial positions of the small belts can be adjusted conveniently and rapidly. The transversely positioning and arranging mechanism has a function of free and automatic micro limit adjustment. Secondary indention is accurate. The pressure of the indention wheel can be adjusted accurately, conveniently and rapidly. Therefore, the quality of the secondary indentation is ensured and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of production equipment of corrugated cartons, and relates to a secondary indentation device for corrugated cartons. Background technique [0002] In the production of corrugated cardboard boxes, after the corrugated cardboard is cut and indented once, the indentation is very easy to rebound and recover. Therefore, the corrugated cardboard must be indented twice before folding, in order to perform the origami under the minimum stress and ensure the folding of the paper. Quality, in the prior art, the secondary indentation device of corrugated box is only one independent secondary indentation machine, the indentation mechanism is installed on the frame, and the indentation support roller is driven by independent power, and in the secondary There is an independent paper feeder before the creasing machine, which feeds the corrugated cardboards one by one into the secondary creasing machine from under the pile of corrugat...

Problems solved by technology

[0002] In the production of corrugated cardboard boxes, after the corrugated cardboard is cut and indented once, the indentation is very easy to rebound and recover. Therefore, the corrugated cardboard must be indented twice before folding, in order to perform the origami under the minimum stress and ensure the folding of the paper. Quality, in the prior art, the secondary indentation device of corrugated box is only one independent secondary indentation machine, the indentation mechanism is installed on the frame, and the indentation support roller is driven by independent power, and in the secondary There is an independent paper feeder before the creasing machine, which feeds the corrugated cardboards one by one into the secondary creasing machine from under the pile of corrugated cardboards, because the corrugated cardboards have no horizontal positioning and sorting during feeding Horizontal positioning mechanism, so it is easy for the secondary indentation to not coincide with the primary indentation, resulting in defective products; the independent paper feeder directly feeds the paper for secondary indentation, it is difficult to standardize continuous paper feeding, and it is even more difficult to install lateral positioning Finishing mechanism; In addition, in the creasing mechanism, the distance between the creasing wheel and the creasing support roller is adjusted—that is, the pressure adjustment structure of the creasing wheel is only adjusted by simple threaded adjustments at both ends of the creasing wheel’s rotating shaft structure, when adjusting, the lifting and lowering of the rotating shaft must be adjusted separately at both ends, not only poor synchronization, but also slow adjustment speed, which is very inconvenient

Therefore, the quality of secondary indentation is difficult to guarantee, and the production efficiency is low
