Description

Technical Field

[0001] The utility model relates to the technical field of die cutter rollers, in particular to a hidden magnetic die cutter roller. Background Art

[0002] Magnetic rollers are suitable for rotary printing and die-cutting industries and electronic product die-cutting industries. Super-strength permanent magnetic blocks are placed locally on the surface of the roller body, making the edge of the flexible blade more secure and able to withstand higher-speed rotary die-cutting.

[0003] However, the permanent magnetic block on the existing die cutter roller is located on the surface of the roller body. The magnetic roller is prone to rust in a humid environment and if it is not maintained in time during use, which greatly reduces the flatness of the knife skin during processing.

[0012] Preferably, a plurality of second plug-in grooves are provided at both left and right ends of the stainless steel sleeve, and when the left and right ends of the stainless steel sleeve are inserted into the fixing ring, the limit blocks are inserted into the second plug-in grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The service life of the magnetic roller is extended by installing a stainless steel sleeve on the outside of the cylinder. Due to the corrosion resistance of stainless steel, the magnetic roller is prevented from rusting, wearing, and overflowing due to human operation and environmental influences, resulting in uneven surface. Due to the strong adsorption performance of the strong magnetic magnet and the thin wall thickness of the stainless steel sleeve, it will not affect the flatness of the knife skin during use, ensuring the die-cutting effect during use.
