Dent adjusting device of dent splitting machine

Abstract

The invention relates to an indentation device for a paper cutting machine, which is an indentation adjustment device for an indentation slitter used for adjusting the indentation depth of the indentation slitter. The power drive wheel of the present invention is installed on the fixed plate, and its inner hole and the power shaft are slidingly matched in the direction of the horizontal axis. The power shaft drives the power drive wheel to rotate, and the eccentric sleeve is installed on the fixed plate. Directional sliding fit, the adjustment shaft drives the eccentric sleeve to rotate, the pre-crimping wheel and the upper crimping wheel are installed on the moving plate, the power driving wheel drives the upper crimping wheel and the pre-cribing wheel to rotate in the same direction; the connecting piece and the eccentric sleeve are smooth The moving fit is hinged with the moving plate through the hinge shaft; the baffle plate and the parallel side of the moving plate slide and fit in the vertical direction, which solves the problem that the existing slitting machine needs independent mechanisms to complete pre-compression and real-compression, pre-compression and real-compression respectively The indentation line has the technical problems of large adjustment and alignment error, large volume and complex structure of the whole machine, difficulty in controlling the indentation depth, and low control accuracy.

Description

technical field [0001] The invention relates to an indentation device of a paper cutting machine, in particular to an indentation adjustment device of an indentation slitting machine. Background technique [0002] At present, the indentation adjustment device of the indentation slitting machine usually only has solid pressure and no pre-compression. Due to the difference in thickness and hardness of the cardboard, some layers may break or even the cardboard will be completely broken if it is directly pressed without pre-compression. , the scrap rate is high. The industry lacks attention and in-depth research on pre-pressing. Even if pre-pressing is used in some creasing and slitting machines, it is technically immature. China Utility Model Patent Authorization Announcement No. CN 201800271 U "A Crimping Wheel Assembly Swing Mechanism for a Slitting Machine" discloses a worm gear motor that is controlled and adjusted by an encoder to drive the beam to rotate through the dri...

Problems solved by technology

[0003] The present invention solves the problem that the existing indentation slitting machine needs independent mechanisms to complete the pre-pressing and real-pressing respectively, the indentation line adjustment and alignment error of pre-pressing and real-pressing is large, the whole machine is large in size and complex in structure, and it is difficult to control the indentation depth , the technical problem of low control precision, to provide a pre-crimping wheel and the upper crimping wheel on the same part, the alignment error of the indentation line of pre-pressing and real pressing is small, the whole machine is small in size, simple in structure, and easy to control the pressing The indentation adjustment device of the indentation slitting machine with high control precision
