A non-stick hot pressing roller for laser packaging

Abstract

The invention discloses a plate-adhesion-free hot compression roll for laser packaging. The plate-adhesion-free hot compression roll for laser packaging comprises a hot compression roll body. A rotating shaft is inserted in the center of an inner cavity of the hot compression roll body. A heating device is arranged on the outer wall of the rotating shaft. A heat conducting cavity is uniformly formed in the outer wall of the heating device. Heat conducting corrugations are arranged on the outer wall of the heat conducting cavity. Heat conducting protrusions are further formed on the outer walls of the heat conducting corrugations uniformly and integrally. A heat conducting aluminum substrate is wrapped on the outer walls of the heat conducting protrusions. An oxide film is further uniformly wrapped on the outer wall of the heat conducting aluminum substrate. Temperature sensors are uniformly inlaid between the heat conducting aluminum substrate and the oxide film and electrically connected with the heating device. The plate-adhesion-free hot compression roll for laser packaging is simple in structure, the anti-adhesion performance of the hot compression roll can be improved effectively, the plate-adhesion phenomenon of laser packaging paper in the laser packaging paper hot compression process is prevented, the quality of the laser packaging paper is guaranteed effectively, and the rate of finished products is increased.

Description

technical field [0001] The invention relates to the technical field of laser packaging equipment, in particular to a non-stick hot pressing roller for laser packaging. Background technique [0002] After the reform and opening up, China's economy has made great progress after more than 30 years of economic construction. In recent years, China's economy has entered a period of economic transition from quantitative growth to qualitative improvement. With the continuous promotion and application of laser packaging materials, the packaging and printing industry closely accompanied by China's economic development has also entered an important transition period from a packaging and printing power to a world power. [0003] Laser packaging is a subdivided industry in the packaging industry. It has achieved rapid development in recent years. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright appearance effects, but also h...

Problems solved by technology

In the process of laser packaging, it is often made by molding, aluminum plating, and compounding. However, traditional hot pressing rollers are prone to plate jamming and sticking when hot-pressing laser packaging paper, which greatly affects the quality of laser packaging.
