Description

Technical Field

[0001] The utility model belongs to the technical field of packaging decoration printing, and in particular relates to a packaging decoration printed matter cutting device. Background Art

[0002] In the current field of packaging decoration printing technology, decoration printing, which mainly prints various packaging materials and packaging containers, is also called packaging decoration printing or packaging printing. It is an important means to turn products into commodities and a necessary condition for commodities to enter the circulation field. The outer packaging of commodities is mostly made of cardboard, and a cutting mechanism is needed to cut the edges and corners, or to cut the continuous printed matter.

[0003] The utility model patent with publication number CN216399753U discloses a cutting device for packaging, decoration and printed materials, including a base and a mounting assembly, a support frame is fixedly mounted on the upper end of the base, hydraulic rods are fixedly mounted on both sides of the upper end of the support frame, a mounting plate connected to the output end of the hydraulic rod is mounted inside the support frame, and clamping assemblies are arranged on both sides of the mounting plate, and a cutting blade is detachably mounted on the lower end of the mounting plate through the mounting assembly, and the clamping assembly includes a pressure strip, a grinding sheet, a connecting plate, a movable rod, a reset spring, an adjusting screw, an adjusting screw sleeve, a connecting block and a limit rod. When the output end of the hydraulic rod drives the mounting plate to move downward, the pressure strip fits the upper end of the cutting object, so that the mounting plate moves downward along the movable rod to stretch the reset spring, and the cutting blade passes through the two pressure strips for cutting, so as to avoid the cutting blade driving the cutting object to deviate upward after cutting, thereby affecting the later cutting.

[0004] However, the above patent has the following shortcomings:

[0005] 1. In the above patent, the movable rod moves downward, and the cutter blade is not required to move the cut material upward after cutting. However, when cutting the edges and corners of cardboard printed materials, paper scraps are likely to remain on the blade of the cutter. After multiple cutting, paper scraps are likely to accumulate on the blade, which affects the cutting accuracy and reduces the service life of the cutter.

[0006] 2. The above patents and commonly used printed matter cutting devices mostly utilize manual feeding, which has low efficiency and reduces the cutting efficiency of printed matter. Utility Model Content
