Adjustable width drying air box of printer

Abstract

The invention discloses an adjustable width drying air box of a printer, and the key point of the technical scheme is that the adjustable width drying air box comprises a box body, wherein the box body is internally provided with an air inlet passage and an inner liner; the air inlet passage is formed by four independent air ways including a first air way, a second air way, a third air way and a forth air way; the inner liner comprises three independent cavities including a left cavity, a middle cavity and a right cavity, and the inner liner is respectively provided with a first air inlet hole, a second air inlet hole, a third air inlet hole and a forth air inlet hole, wherein the first air inlet hole is communicated with the left cavity, the second air inlet hole and the third air inlet hole are communicated with the middle cavity, and the forth air inlet hole is communicated with the right cavity; the first air way, the second air way, the third air way and the forth air way are correspondingly connected with the second air inlet hole, the third air inlet hole, the forth air inlet hole and the first air inlet hole; and the inner liner is horizontally provided with a plurality ofair nozzles communicated with the outside.

Description

【Technical field】 [0001] The invention relates to a printing machine, and more specifically relates to an adjustable width drying bellows for the printing machine. 【Background technique】 [0002] In the existing gravure or letterpress printing machines, generally one type of printing machine can only print and dry printed matter with little change in width. When drying after printing, due to the bellows used for drying, the length of the air nozzle is Fixed, once the printing machine is purchased, the length of the air nozzle of the bellows is also fixed. [0003] If you want to dry printed matter with a width greater than the length of the bellows nozzle, this printing machine cannot achieve it. At this time, you need to replace the printing machine with a longer bellows nozzle to achieve it; if you want to dry the printed matter with a width smaller than the bellows nozzle Although the printed matter of the length can be realized, the hot air in the air nozzle part wider ...

AI Technical Summary

Problems solved by technology

[0003] If you want to dry printed matter with a width greater than the length of the bellows nozzle, this printing machine cannot achieve it. At this time, you need to replace the printing machine with a longer bellows nozzle to achieve it; if you want to dry the printed matter with a width smaller than the bellows nozzle Long-length prints can be realized, but the hot air at the air nozzle part wider than the width of the material will be wasted in vain. For small prints, it will cause a waste of energy

In this way, printing machines of various specifications are required to print and dry printed matter of different widths, which costs a lot
