Combined crimping device of corrugated case print fluting machine

Abstract

The invention discloses a combined crimping device of a corrugated case print fluting machine. The combined crimping device comprises a preliminary pre-pressing wheel set and a crimping and forming wheel set, wherein the preliminary pre-pressing wheel set comprises a preliminary pre-pressing upper wheel and a preliminary pre-pressing lower wheel which have a plane-to-plane structure; the crimping and forming wheel set comprises a moderate crimping upper wheel of a plane-to-recess structure, a moderate crimping lower wheel, and a main crimping and forming upper wheel and a main crimping and forming lower wheel of a recess-to-bump structure; or the crimping and forming wheel set only comprises a main crimping and forming upper wheel and a main crimping and forming lower wheel of a recess-to-three-bump structure; each wheel is arranged on a corresponding shaft through a wheel seat; each wheel seat is provided with a shift fork groove; and a shift fork is arranged in the shift fork groove. By using the combined crimping device provided by the invention, a crimped case does not crack, wrinkles are not produced inside a crimping line, the crimping line is accurate in positioning and no deflection and displacement are guaranteed, the case quality is improved, and the production cost is effectively reduced; crimping, fluting and central positioning of the print fluting equipment are performed in parallel; synchronous linkage and adjustment are realized; and the combined crimping device is easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of carton packaging machinery, in particular to a creasing device of a corrugated carton printing and slotting machine. Background technique [0002] With the continuous development of the economy, the demand for carton packaging is increasing, involving more and more industries, and the packaged goods are widely used in advanced assembly line production operations and automatic box packaging, so the geometric dimension accuracy of paper bonding molding is more demanding. In some industries, such as tobacco and pharmaceutical industries, due to the high degree of automation, the requirements for cartons must be almost insignificant, otherwise it will affect the automated flow operation, cause production failure, and bring greater losses. [0003] The creasing device is an important part of the printing slotting machine. The corrugated cardboard is pressed out by the creasing device, and the corrugated cardbo...

AI Technical Summary

Problems solved by technology

At present, the creasing device of the corrugated box printing slotting machine is usually only equipped with two sets of creasing wheels, that is, a simple flat pre-pressing wheel and a convex-to-flat main pressing wheel. There is only one scoring line at the folding part, and the effect is It is: ①The inner and surface paper of corrugated cardboard are easy to burst; ②The folding time line is easy to be misplaced, and the two sides of the inner folding line are packaged or sunken, resulting in wrinkles, and the carton waste rate is high.

On the other hand, the design of the existing corrugated box printing and slotting machine also has defects. The creasing wheel and the slotting wheel cannot be adjusted in conjunction. Only separate adjustments are used, which makes the operation complicated, the positioning is not accurate, and the efficiency is low.
