The utility model relates to a uniform temperature bronzing roll for a bronzing machine. The problem of inconsistent temperature of hot stamping roll is mainly solved. The two ends of the roller body are threaded together with the left plug and the right plug. The left plug and the right plug are provided with through holes. The roller axle passes through through the through holes and the holes and the two ends of the roller axle extend out of the roller body. The center of the roller axle is provided with hot oil passages running through both ends of the roller axle. The roller axle located in the holes is provided with several oil outlets connected with the hot oil passage. The diameter of the oil outlet gradually increases from left to right, and the right end of the hot oil passage is one. The body is formed with a sealing plate, an oil outlet hole is arranged on the right plug, and the oil outlet hole is connected to the hot oil channel on the right side of the sealing plate. The utility model uses a roll shaft as an oil inlet pipeline to directly feed hot oil into the inner part of the gilding roll, changes the structure of oil inlet at one end, and installs oil outlet holes which increase in turn from the oil inlet end to the oil outlet on the roll shaft, so that the plate roll is heated more uniformly, so that the mechanical width of the gilding roll can be enlarged, the gilding width can be enlarged, and the gilding efficiency can be improved.

一种烫金机用均温烫金辊
本技术涉及烫金辊,具体涉及一种烫金机用均温烫金辊。
技术介绍
在印刷的加工工艺中,烫金是常见的,最常用的热烫可分为平烫和圆烫,热烫常用的加热方式有电热和油热。电热是给加热板内的电阻丝通电使发热并用温控器稳定其温度。其结构简单成本低,广泛用于平烫。现有的油热烫金中烫金辊加热油进口端温度一般比远端高出3~5℃,最高可达8~10℃,从而造成烫金效果不一致影响烫金的质量,从而制约烫金的宽度,影响烫金的工效。
