Printing roller for temperature-adjustable type double-loop multi-channel wide-range film pressing machine

Abstract

The invention discloses a printing roller for a temperature-adjustable type double-loop multi-channel wide-range film pressing machine. The printing roller comprises a spindle body, an oil way shaft, a water way shaft, oil way passageways, water way passageways, an oil way outlet pipe, a water way inlet pipe, a water way outlet pipe and separation boards, wherein the spindle body is in a hollow structure and comprises an inner cavity and a shaft wall; the oil way passageways and the water way passageways are arranged in the shaft wall of the spindle body; the oil way shaft and the water way shaft are arranged at two ends of the spindle body respectively and symmetrically; the oil way shaft is communicated with an inner cavity of the spindle body; communication holes which enable the inner cavity of the spindle body to be communicated with the oil way passageways are arranged on the inner side of the shaft wall of the spindle body so as to form oil way loops sequentially penetrating through the oil way shaft, the inner cavity of the spindle body, the communication holes, the oil way passageways, the oil way outlet pipe and the oil way shaft; the water way passageways are communicated with the water way inlet pipe and the water way outlet pipe respectively to form a water way loop sequentially penetrating through the water way shaft, the water way inlet pipe, the water way passageways, the water way outlet pipe and the water way shaft; and the separation boards are arranged between the inner cavity of the spindle body and the water way shaft. The printing roller is wide in application range and can meet different performance index requirements.

Description

technical field [0001] The invention relates to a plate roller for a temperature-adjustable double-circuit multi-channel wide-width film press. Background technique [0002] Laminating technology was born in the United States in the 1950s. In the mid-1960s, my country also began to study the laminating process, and successfully tested it in printing, and it was widely used soon after. The coated printed matter has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, which not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter. Antifouling, abrasion resistance, folding resistance, chemical corrosion resistance and other protective effects. At present, its application can be seen in various book covers, packaging and decoration printed materials, calendars, maps, mobile phone films, etc. [0003] The traditional plate roller structure of film press uses wel...

AI Technical Summary

Problems solved by technology

[0003] The traditional plate roller structure of film press uses welding process to realize the pipeline connection of oil channel. If the welding process is not good, oil leakage is easy to occur during the operation of the machine, thus polluting the coated product

The oil channel and water channel of the plate roller structure of the traditional film press have a high degree of coupling in the temperature field in the area close to each other, resulting in a lower temperature in this part of the working area than in other areas. Inevitably uneven, which affects the quality of the coating

The adjacent area of ​​the oil passage area and the water passage area of ​​the traditional film press is prone to slight mutual leakage, which affects the quality of the film coating

Once the structure of the traditional film press plate roller is successfully designed, its size cannot be changed flexibly, and the size is generally small, so the scope of application can no longer meet the needs of development in the new era, such as architectural decoration, decoration printing, etc. in the future. Industry needs wide-format film presses with good performance

In addition, the structure of traditional film press rollers is poor in portability, and its working area often cannot be flexibly changed to adapt to different lamination index requirements.
