Position correction method, die cutting method, position correction device and die cutting machine

Abstract

The invention relates to the technical field of die cutting, in particular to a position correction method, a die cutting method, a position correction device and a die cutting machine. According to the position correction method, the die cutting method, the device and the die cutting machine provided by the embodiment, theoretical deviation of a blade of a cutter arranged on a die cutting wheel relative to operation of the front end of a material to be cut when the front end of the material to be cut is conveyed to an initial cutting position in the current operation mode can be estimated; and if the estimated theoretical deviation is out of a preset deviation range, a driving device is controlled to drive the die cutting wheel to rotate at a variable speed based on the theoretical deviation, so that when the front end of the material to be cut is conveyed to the initial cutting position, actual deviation between the position of the blade and the initial cutting position is within the preset deviation range. Therefore, according to the embodiment, the blade and the front end of the material to be cut can reach the initial cutting position at the same time by controlling the variable speed motion of the die cutting wheel, so that the die cutting precision is improved.

Description

technical field [0001] The present invention relates to the technical field of die-cutting, in particular to a position correction method, a die-cutting method, a position correction device and a die-cutting machine. Background technique [0002] Corrugated cardboard is widely used in the packaging industry due to its simple production process and low cost. At present, in the process of mass processing of corrugated cardboard, rotary die-cutting machines are generally used. The rotary die-cutting machine includes a rubber cushion roller and a die roller, and the corrugated cardboard is cut into shape under pressure between the rubber cushion roller and the die roller. Die-cutting is usually a cutting process in the post-processing of printed matter, which can cut printed matter or other products to the desired shape according to the pre-made graphics. [0003] In the process of realizing the present invention, the inventor found that in the prior art, due to the relatively...

AI Technical Summary

Problems solved by technology

When the time point when the corrugated cardboard reaches the initial cutting position of the die cylinder is not correct, it will lead to insufficient die-cutting accuracy. If the printing process has been completed in the previous process, it will easily cause the embossed cardboard to be scrapped

Therefore, the accuracy and yield cannot be guaranteed, which increases unnecessary manufacturing costs
