Problems solved by technology

At present, most of the UV_LED drying devices used for UV ink drying process are full-cycle and full-width drying, but many printed products are not full-width patterns or do not require full-width drying treatment, such as securities, cigarette labels, etc.; at the same time For sheet-fed printing machines, due to the existence of cylinder gaps or printing small-format prints on large-format printing machines, it is not necessary to perform full-cycle drying, so drying in parts that do not need to be dried is likely to cause waste of resources

Abstract

The invention discloses a UV_LED drying device for a printing machine, which comprises a cooling base plate, a bracket assembly, a UV_LED light emitting module, a bracket position adjustment assembly and an electrical control assembly; the cooling base plate is equipped with a bracket assembly; the bracket assembly is equipped with a UV_LED light emitting module; The bracket position adjustment component is used to adjust the position between the bracket component and the cooling bottom plate; the electrical control component is used to control the UV_LED light emitting module. The present invention can adjust the position between the bracket assembly and the cooling bottom plate, so as to adjust the distribution position of the UV_LED light-emitting modules on the cooling bottom plate; and can control the opening or closing of the UV_LED light-emitting modules, so as to turn off the UV_LED for parts that do not need to be dried. The power supply of particles, thereby reducing useless work, improving energy utilization, reducing the overall loss of the system, and improving the life of UV_LED particles.

Description

technical field [0001] The invention relates to the technical field of drying devices for printing machines, and more particularly to a UV-LED drying device for printing machines. Background technique [0002] At present, the traditional UV drying system uses metal halide lamp as the light source. Metal halide lamp has the advantages of high power and wide spectrum, and can be used to dry the UV ink on the printed product during the printing process, but it has obvious defects such as It is large in size, contains more infrared rays, and generates a large amount of heat. [0003] With the rapid development of LED technology in recent years, the efficiency and power of UV_LED (ultraviolet light-emitting diode) chips have also been improved accordingly, so that UV_LED chips can be used for UV ink drying. Compared with metal halide lamps, UV_LED has the characteristics of low calorific value, small size of single particle, flexible shape of light-emitting surface, no need for ...
