Description

The present invention provides a position-switchable inkjet device that switches relative positions between inkjet heads as needed to achieve production capacity optimization, which is particularly applicable to large UV inkjet printer applications. Will be done.

UV inkjet can print on printed matter of many different materials or thicknesses, provides relatively good printing speeds, and not only can achieve stable and consistent print quality, but also its reliability. Some performance also allows users to quickly complete printing by saving the work and time of making color separation screens, making UV inkjet printers for professional commercial output applications such as advertising, posters and reproduction of high quality artwork. Widely applied.

UV inkjet printers found in the current market are mainly provided with an inkjet module that can move back and forth under the control of the sliding plane of the machine base, and a plurality of ink cartridges are provided above the inkjet module and below the inkjet module. An inkjet head corresponding to each of a plurality of ink cartridges, for example, a color or special color (white or transparent color) inkjet head is provided, and ink is jet-printed on an object to be printed waiting to be printed by a nozzle at the bottom of the inkjet head, and an inkjet module is used. A UV lamp installed on the side irradiates the ink jet-printed on the object to be printed, and the ink is rapidly cured and solidified.

The current method of increasing the special color output production capacity is to arrange the special color inkjet heads and the color inkjet heads in different rows, and thus complete the output of color ink and special color ink at the same time in one workflow. Some types of inkjet head array design schemes will warp and reduce their performance when applied to stack printing or overprinting.

Therefore, those skilled in the art and users are desperate for how to effectively improve the printing defects that occur when the UV inkjet printer performs stack printing, and further improve the printing efficiency of the UV inkjet.
An object of the present invention is to provide a position-switchable inkjet device having a simple structure, low cost, and capable of effectively increasing printing speed and optimizing production capacity.

In order to achieve the above object, the position-switchable inkjet device of the present invention includes a main body and a plurality of inkjet heads, and is provided with at least one first region and a plurality of second regions, and the first region and the plurality of The first inkjet head includes a main body in which second regions are arranged at intervals, a first inkjet head which is installed in the main body and has special color ink, and a plurality of second inkjet heads which have color ink. The first inkjet head or the plurality of second inkjet heads are installed in the first region, the second inkjet head is installed in the second region, and the first inkjet head or a plurality of second inkjet heads move on the first region or the second region. Can be done.

At the time of implementation, the plurality of second inkjet heads are fixed on the second region, the first inkjet head can move on the first region, and the first inkjet head is positioned. Accurate positioning is possible after moving due to the structure.

At the time of implementation, the first inkjet head is fixed on the first region, the plurality of second inkjet heads move synchronously on the second region, and the plurality of second inkjet heads move. The positioning structure enables accurate positioning after movement.

At the time of implementation, the positioning structure comprises a positioning member installed around the first region or the second region and a positioning block installed on the first inkjet head or a plurality of second inkjet heads, and the first inkjet When moving the head or the plurality of second inkjet heads, the first inkjet head or the plurality of second inkjet heads are accurately positioned at a predetermined position after the positioning block conflicts with the positioning member.

The position-switchable inkjet device of the present invention has a simple structure, is low in cost, can effectively increase the printing speed, and can optimize the production capacity.

It is a flow chart of the Example of this invention. It is a state explanatory diagram of the continuous operation at the time of carrying out the Example of this invention.

With reference to FIGS. 1 and 2, it is the most preferred embodiment of the repositionable inkjet device of the present invention.

The position-switchable inkjet device of the present invention includes a main body 1 and a plurality of inkjet heads 2, and at least one first region 11 and a plurality of second regions 12 are provided on the main body 1, and the first region 11 is provided. And the plurality of second regions 12 are arranged on the main body 1 at intervals.
The plurality of inkjet heads 2 are respectively installed on the main body 1, and the plurality of inkjet heads 2 include a first inkjet head 21 having a special color ink and a plurality of second inkjet heads 22 having a color ink. Further, the first inkjet head 21 is installed on the first region 11, the second inkjet head 22 is installed on the second region 12, and the first inkjet head 21 or a plurality of second inkjet heads 21 are installed. The inkjet head 22 can move on the first region 11 or the second region 12.

The plurality of second inkjet heads 22 are fixed on the second region 12, the first inkjet head 21 can move on the first region 11, and the first inkjet head 21 is The positioning structure 3 enables accurate positioning after movement (see FIG. 1). The first inkjet head 21 is fixed on the first region 11, and the plurality of second inkjet heads 22 can move synchronously on the second region 12, and the plurality of second inkjet heads The 22 can be accurately positioned after being moved by the positioning structure 3 (see FIG. 2).

Among them, the positioning structure 3 is composed of a positioning member 31 installed around the first region 11 or the second region 12 and a positioning block 32 installed on the first inkjet head 21 or a plurality of second inkjet heads 22. Then, when the first inkjet head 21 or the plurality of second inkjet heads 22 is moved, after the positioning block 32 conflicts with the positioning member 31, the first inkjet head 21 or the plurality of second inkjet heads 22 are designated. Can be accurately positioned at the position of.

Therefore, according to the above design, the user switches the position of the first inkjet head having the special color ink or the plurality of second inkjet heads having the color ink in the process of inkjet according to the needs of different use, and It can be completed on the same inkjet module, the structural design is simple and the cost is low, the printing efficiency of stack printing can be greatly improved, and at the same time, the first inkjet head or a plurality of second inkjet heads can be obtained by designing the positioning structure. After moving, it can be accurately positioned at an accurate position, and the movement does not cause the problem of printing misalignment.

The above-mentioned contents are specific examples of the present invention and technical means for operating the present invention, and many modifications and modifications can be derived by disclosure or teaching of the main text, and are regarded as changes in equivalent effects made by the concept of the present invention. And its action still does not go beyond the substantive spirit contained in the specification and drawings, both of which should be considered within the technical scope of the invention.

Summarizing the above, based on the above-mentioned disclosed contents, the present invention certainly can achieve the expected object of the invention, provides a position-switchable inkjet device, and has extremely industrial applicability value.
