AI Technical Summary
The existing layout of varnish printheads and UV lamps in inkjet printers cannot simultaneously achieve matte and glossy effects on the same image.
The system employs UV lamp groups arranged symmetrically on both sides of the printing area. Each UV lamp group contains multiple UV lamps and is divided into multiple UV lamp areas. Each UV lamp area is independently controlled. Varnish nozzles are also arranged in the printing area. The matte and glossy effects of the varnish are achieved by controlling the switching of the UV lamp areas.
It enables the simultaneous application of both matte and glossy finishes on the same image, meeting the printing needs for different effects.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkjet printers, specifically a UV lamp and printhead layout structure for inkjet printing. Background Technology
[0002] The existing layout structure of the varnish printhead and UV lamp of inkjet printers is as follows: Figure 1 As shown, large UV lamps and small UV lamps are arranged symmetrically on both sides of the varnish nozzle. When the position of the small UV lamp is adjusted, only matte or glossy varnish can be printed separately, and it is impossible to achieve both matte and glossy effects on the same image at the same time. Utility Model Content
[0003] This invention provides a UV lamp and printhead layout structure for inkjet printing, to solve the problem that the existing inkjet printer printhead and UV lamp layout structure cannot simultaneously achieve matte and glossy effects on the same image.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A UV lamp and printhead layout structure for inkjet printing is characterized by comprising UV lamp groups arranged on two symmetrical sides of the printing area, each UV lamp group containing multiple UV lamps, and the multiple UV lamps in each UV lamp group being divided into multiple UV lamp regions along a straight line, the multiple UV lamp regions on both sides being parallel to each other in the straight line distribution direction, each UV lamp region being independently controlled to be turned on or off, the UV lamp regions on both sides being symmetrically positioned, and at least one set of varnish printheads being arranged in the printing area between at least two symmetrically positioned UV lamp regions.
[0006] Furthermore, each UV lamp zone contains the same number of UV lamps.
[0007] In this invention, by controlling the opening or closing of each UV lamp area in segments, the matte and glossy effects of varnish can be achieved on the same screen. Attached Figure Description
[0008] Figure 1 This is a layout diagram of existing varnish nozzles and UV lamps.
[0009] Figure 2 This is a structural diagram of the varnish nozzle and UV lamp according to an embodiment of the present invention. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0011] like Figure 2As shown, this embodiment discloses a UV lamp and printhead layout structure for inkjet printing, including UV lamp groups arranged on the left and right symmetrical sides of the printing area. Each UV lamp group on each side is composed of a number of UV lamps, and the multiple UV lamps in each UV lamp group are divided into six UV lamp regions along a straight line in the front-back direction, namely UV lamp region 1, UV lamp region 2, UV lamp region 3, UV lamp region 4, UV lamp region 5, and UV lamp region 6. Each UV lamp region contains the same number of UV lamps.
[0012] The UV lamp areas 1, 2, 3, 4, 5, and 6 on both sides are symmetrically positioned and correspond one-to-one. Each UV lamp area is independently controlled to open or close, thus achieving segmented control of the left and right UV lamp areas. The switching on and off of any segment of the UV lamp area can be achieved manually or via software. At least one varnish nozzle is arranged in the printing area between at least two sets of symmetrically positioned UV lamp areas.
[0013] This embodiment is illustrated by arranging a varnish nozzle A in the printing area between the left UV lamp area 4 and the right UV lamp area 4, and arranging a varnish nozzle B in the printing area between the left UV lamp area 5 and the right UV lamp area 5. Varnish nozzle A is close to the right UV lamp area 4, and varnish nozzle B is located in the middle between the left UV lamp area 5 and the right UV lamp area 5.
[0014] When working, select to turn off the UV lamp areas 5 on both sides corresponding to the varnish printhead B, and turn on the other UV lamp areas. When the varnish printhead B prints, it can achieve the glossy effect of the varnish.
[0015] Select the UV lamp area 4 on both sides corresponding to the varnish printhead A. When the varnish printhead A prints ink, a matte effect of the varnish can be achieved.
[0016] When UV lamp areas 4 and 6 on both sides operate simultaneously, and varnish is dispensed from nozzles A and B, both matte and glossy effects of the varnish can be achieved on the same image. The matte effect requires the UV lamps and varnish to be in the same row, meaning the varnish is sprayed and cured simultaneously with the UV lamps. The glossy effect requires the UV lamps and varnish to be staggered, meaning the varnish is sprayed and then cured by the UV lamps after a certain period of time. This allows both matte and glossy effects to be achieved simultaneously on the same image.
[0017] The preferred embodiments of this utility model have been described in detail above with reference to the accompanying drawings. These embodiments are merely descriptions of preferred embodiments and are not intended to limit the concept and scope of this utility model. The various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. Such combinations, as long as they do not violate the spirit of this utility model, should also be considered as part of this disclosure. To avoid unnecessary repetition, this utility model will not further describe all possible combinations.

Within the scope of the technical concept of this utility model and without departing from the design idea of this utility model, all modifications and improvements made by those skilled in the art to the technical solution of this utility model should fall within the protection scope of this utility model. The technical content for which protection is sought in this utility model has been fully recorded in the claims.
