Description

TECHNICAL FIELD

[0001] The utility model belongs to paper box production technical field, specifically relates to a die -cutting machine for paper box production. BACKGROUND

[0002] In the field of paper box production, die cutting is a key processing technology for cutting large paperboard into specific shape and size of paper box blank. The traditional paper box production die cutting machine has some significant problems and deficiencies in the running process.

[0003] In the past die cutting machine, the fixing mode of paper box board is often simple and rough, usually only through mechanical clamping or simple pressing to realize fixation. However, this fixing mode needs to increase electrical elements, thereby leading to the increase of cost.

[0004] In addition, the die cutter body of die cutting machine will produce a lot of heat in the long time, high strength working process. If it cannot be cooled down effectively in time, high temperature will accelerate the wear and tear and aging of die cutter body, shorten its service life. This not only increases the maintenance cost of die cutting machine, but also will lead to the reduction of production efficiency because of frequent replacement of die cutter body.

[0005] At the same time, in the die cutting process, various impurities and debris are easy to accumulate on the die cutter body, if they cannot be removed in time, these impurities will affect the precision and quality of die cutting, further aggravate the wear and tear of die cutter body.

[0006] For the base part, due to frequent die cutting operation, impurities and waste will also accumulate on the base. If these accumulations are not cleaned, it will affect the accuracy of paper box board placement position, thereby indirectly affecting the precision of die cutting.

[0007] Therefore, we propose a die cutting machine for paper box production, which can not only fix the paper box board to prevent the paper box board from shifting during die cutting, reduce the cost investment, but also cool and remove the die cutter body, improve the service life of the die cutter body.
