Description

A rotary printer with high drop

technical field

The invention relates to the technical field of printing equipment, in particular to a rotary printer with a high drop.

Background technique

When the UV cylindrical printer is printing, the workpiece is clamped on the clamping device, its axis is set along the horizontal direction, and the workpiece rotates along its axis with a fixed axis. The nozzle is located above the workpiece, and it is necessary to make the nozzle and the workpiece to be printed separately The distance between the positions is the same and fixed to ensure the printing effect.

A UV printer that prints high-drop materials, also known as a UV high-jet printer. The high-drop uv printer can solve the printing problem of materials with a concave-convex drop of less than 20mm, but it can't do anything for materials with a concave-convex drop greater than 20mm.

Under normal circumstances, the maximum height difference of existing printing equipment can reach about 20mm, but the high height difference also brings a certain burden to the nozzle itself. Whether it is an industrial technology nozzle or an inexpensive and easy-to-use Epson nozzle, they all belong to the piezoelectric nozzle. The core principle to achieve a high drop is to increase the voltage to the nozzle to make it eject ink faster. Each nozzle has its optimal voltage environment, forcibly pressurizing the nozzle will bring additional burden, which is why the service life of the nozzle will be reduced while achieving a high drop.

But the high drop also brings a lot of benefits to the UV printing industry. In the past, the heads of children's dolls, sports shoes, and non-cylindrical bottles could not be printed, but now they can basically be printed. This not only broadens the scope of use of UV printing equipment, but also facilitates many customers.

High-drop uv printers are very prominent in the engraving and painting industry. In the early engraving background walls, engraving materials were usually first engraved with an engraving machine, and then the uv printer was used for alignment and coloring. Not to mention the high equipment cost, the process is even more cumbersome. Now The engraving can be completed with a high drop uv printer.

To sum up, the market needs high-drop uv printers. In order to solve the problem of high-drop printing in industries such as toys, engravings, and thermos cups, broaden the scope of use of UV printing equipment, and solve the printing problem of materials with a concave-convex drop greater than 20mm without increasing the voltage to the nozzle and reducing the service life of the nozzle It is one of the technical problems to be solved in this field.
