Cutting device for package printing and using method thereof

Abstract

The invention discloses a cutting device for package printing and a using method thereof. The cutting device comprises a rack; a fixed frame and a sliding frame capable of moving on the upper surfaceon the rack are arranged on the upper surface of the rack; an electric positioning cylinder is mounted on the upper surface of the sliding frame; a positioning plate is connected with an output end ofthe electric positioning cylinder; a vertical first screw rod is rotationally mounted on the upper surface of the fixed frame; a second screw rod is coaxially connected with the bottom end of the first screw rod; a first lifting plate and a second lifting plate are separately mounted on the outer sides of the first screw rod and the second screw rod through threads; a cutting knife is connected to the bottom surface of the first lifting plate; and a cutting bottom plate is arranged on the upper surface of the second lifting plate. The cutting device has the benefits that the lifting of the cutting bottom plate can be realized, and the cutting bottom plate assists the cutting knife in cutting, so that the influence on paperboard transporting can be prevented, and the cutting quality is ensured; and the sliding frame is driven by a positioning driving piece to move to adjust the position of the positioning plate, so that the positioning requirements on different cutting lengths can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of cutting devices, in particular to a cutting device for packaging and printing and a method for using the same. Background technique [0002] In the packaging and printing process of cardboard, it is necessary to use a cutting device to cut the cardboard. In order to ensure the cutting quality, a cutting bottom plate is provided under the cutting knife, and the cardboard is cut through the cutting bottom plate and the cutting knife. However, the position of the cutting bottom plate of the current cutting device is fixed, and there is friction between the cutting bottom plate and the cardboard when the cardboard is conveyed, which affects the conveying accuracy of the cardboard, thereby affecting the cutting quality; at the same time, it is impossible to realize the positioning of different cutting lengths. limited. Contents of the invention [0003] The purpose of the present invention is to provide a c...
