Line pressing device of corrugated carton printing and slotting machine

Abstract

The invention relates to the technical field of corrugated carton processing, and discloses a line pressing device of a corrugated carton printing and slotting machine. The line pressing device comprises a top pressing shaft rod, the bottom of the top pressing shaft rod is provided with a bottom pressing shaft rod, the surface of one end of the top pressing shaft rod is fixedly sleeved with a first line pressing wheel, one side of the first line pressing wheel is movably connected with a second line pressing wheel, and the interior of the middle of the second line pressing wheel is clamped to the surface of one end of the top pressing line shaft rod. According to the line pressing device of the corrugated carton printing and slotting machine, six sealed containers, namely four first hollow cylinders in the interior of a first liquid type cooling mechanism and two second hollow cylinders in the interior of a second liquid type cooling mechanism, are used for receiving cooling liquid, so that cooling protection of the first line pressing wheel, the second line pressing wheel, a line pressing convex disc, a third line pressing wheel and a fourth line pressing wheel is realized, the heat dissipation efficiency of the structure after heat production due to processing is improved, the service life of the line pressing convex disc is prolonged, and the processing quality of a corrugated board is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated carton processing, in particular to a creasing device of a corrugated carton printing and slotting machine. Background technique [0002] Printing slotting machine, also known as water-based printing slotting machine, carton printing slotting machine, ink printing slotting machine or corrugated cardboard printing slotting machine The comprehensive carton processing equipment that integrates five processes into one is an indispensable post-processing equipment in the production of corrugated cartons. According to different color groups, the printing slotting machine can be divided into single-color, double-color, three-color, four-color, etc. This type of machine has a wide range of processing surfaces, but there are still some problems in the crimping device of the existing printing and slotting machine, mainly because the heat dissipation efficiency of the existing crimping device is relativel...

AI Technical Summary

Problems solved by technology

[0002] Printing slotting machine, also known as water-based printing slotting machine, carton printing slotting machine, ink printing slotting machine or corrugated cardboard printing slotting machine, is the It is a comprehensive carton processing equipment that integrates five processes of cardboard printing, slotting, corner cutting, creasing and edge trimming. It is an indispensable post-processing equipment in corrugated carton production. According to different color groups, printing and opening The slotting machine has single-color, double-color, three-color, four-color and other models, and the processing surface is very wide. However, there are still some problems in the crimping device of the existing printing slotting machine, mainly because the existing crimping device is not compatible with During the friction processing of corrugated cardboard, the heat dissipation efficiency is relatively slow, which in turn affects the service life of the crimping disc inside the crimping device and the processing quality of corrugated cardboard. , the cost of replacing the entire creasing wheel is not only high, but also the cycle of replacement and maintenance is relatively long. Therefore, in view of the above problems, the present invention provides a creasing device for a corrugated box printing and slotting machine
