Description

Technical Field

[0001] The utility model relates to the technical field of printers, and in particular to a double-sided printing UV printer. Background Art

[0002] UV printers mostly refer to UV printers, but they can also include other types of UV printers. For example, UV printers utilize UV ​​curing technology. The developed printing ink reacts with a specific type of light produced by a UV lamp, rapidly curing the ink onto the print medium and forming a variety of designs. UV printers are currently a very popular printing device in the advertising industry.

[0003] At present, the printing method adopted by UV printers is mostly to install UV lamps on both sides of the printing carriage. As the printing carriage moves back and forth, the UV lamps complete the curing of the printing ink.

[0004] This printing method has basically become a specific printing form of UV printers.

[0005] However, with the development of printhead and ink technology, the printing efficiency of printheads has been greatly improved, and the reciprocating motion speed has the potential to increase. However, UV lamp curing requires a specific time, and if the speed is too fast, it will easily affect the curing effect.

[0006] On the other hand, the dynamic walking UV lamp itself has limited power. Due to the limited space of the reciprocating motion of the printing carriage, the UV lamp cannot be made too large.

[0007] These many restrictions require that the current design model of UV printers need to be adjusted to meet the diverse needs of UV printing.

[0008] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0009] The purpose of the present invention is to address the deficiencies of the prior art and thereby provide a double-sided printing UV printer with a rear-mounted curing lamp, separated from a printing carriage, and improved curing performance.

[0010] In order to achieve the above-mentioned object, the technical solution adopted by the present invention is: a double-sided printing UV printer, comprising two printing carriages, two light curing modules and a support roller system;

[0011] The support roller is used to support the printing medium to form a vertical or oblique printing channel;

[0012] The two printing carriages are arranged on both sides of the printing channel, and the printing surfaces of the two printing carriages face the printing channel;

[0013] The two light curing modules are arranged on both sides of the printing channel, and the two light curing modules are respectively arranged downstream of the printing carriage on the corresponding side, and the irradiation direction of the light curing modules is toward the printing channel.

[0014] Based on the above, the printing surfaces of the two printing carriages are arranged opposite to each other.

[0015] Based on the above, the printing surfaces of the two printing carriages are staggered.

[0016] Based on the above, the two light curing modules are fixed curing lamps with a span equal to or greater than the printing width.

[0017] Based on the above, the irradiation directions of the two light curing modules are opposite to each other.

[0018] Based on the above, the two light curing modules are arranged at different heights.

[0019] Based on the above, the two light curing modules are two carriages that move back and forth horizontally along the printing width, and curing lamps are installed on the carriages.

[0020] Based on the above, the two carriages and the irradiation directions of the curing lamps are opposite to each other.

[0021] Based on the above, the two trolleys are staggered in height.

[0022] Based on the above, the roller system includes two groups of clamping rollers arranged at both ends of the printing channel, wherein at least one group of the clamping rollers is an active roller group to provide power.

[0023] The present invention has substantial features and progress over the prior art. Specifically, the present invention has the following advantages:

[0024] The light-curing module is separated from the print carriage. The light-curing efficiency no longer limits or restricts the print carriage's operating speed, which can maximize printing efficiency. Matching this, although the stepping speed of the printing medium is also improved, since the stepping speed is much slower than the operating speed of the print carriage, it will not restrict the performance of the light-curing module itself. Therefore, the structural independence and separation of the two contribute to further optimization of their respective performance.

[0025] The light curing module can be designed as a fixed wide-width form or a reciprocating motion form according to the needs of the user, and has a diverse design basis. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0032] Example 1

[0033] like Figure 1 and Figure 3 As shown, a double-sided printing UV printer includes two printing carriages 1, two light curing modules 2 and a support roller system 3.

[0034] The support roller system 3 is used to support the printing medium 4 to form a vertical or oblique printing channel 5.

[0035] The two printing carriages 1 are arranged on both sides of the printing channel 5, and the printing surfaces of the two printing carriages 1 face the printing channel;

[0036] The two light curing modules 2 are arranged on both sides of the printing channel 5 . The two light curing modules 2 are respectively arranged downstream of the printing carriage 1 on the corresponding side. The irradiation direction of the light curing modules 2 is toward the printing channel 5 .

[0037] In this embodiment, the printing surfaces of the two printing carriages 1 are arranged opposite to each other.

[0038] The two light curing modules 2 are fixed curing lamps with a span equal to or greater than the printing width. The irradiation directions of the two light curing modules are opposite to each other.

[0039] The roller system includes two groups of clamping rollers 6 arranged at both ends of the printing channel, wherein at least one group of the clamping rollers 6 is an active roller group to provide power.

[0040] Working principle description:

[0041] The printing medium is unwound from the feeding roller, supported by the support roller system 3, printed through the printing channel, and rewound to the receiving roller to complete the entire process.

[0042] When the printing medium passes through the printing channel 5, the two printing carriages 1 print on the surface of the printing medium from both sides of the printing medium 4. At the same time, the printing medium moves steadily under the action of the support roller system 3. When it reaches the position of the light curing module, the curing light projected by the light curing module cures the ink and develops the color, completing the light curing printing process.

[0043] In the current industry, light curing mainly refers to UV lamp curing, but it can also be applied to the curing methods of other materials or lamps.

[0044] Example 2

[0045] like Figure 2 As shown, the main difference between this embodiment and embodiment 1 is that the printing surfaces of the two printing carriages are staggered.

[0046] The two light curing modules are set at staggered heights.

[0047] The staggered printing method is mainly used for printing different patterns on both sides. The two printing carriages do not interfere with each other, and the two light curing modules also do not interfere with each other.

[0048] It should be noted that the misalignment of the printing carriage and the misalignment of the light-curing module are not in a one-to-one matching relationship. In other embodiments, when the printing carriages are relative, the light-curing modules can also be set in a misaligned manner. Correspondingly, when the printing carriages are misaligned, the light-curing modules can also be set in a relative manner.

[0049] The above-mentioned collocation relationships can be flexibly combined and used as needed.

[0050] Example 3

[0051] like Figure 4 As shown, the difference between this embodiment and embodiment 1 or 2 is that the two light curing modules are two carriages that move back and forth horizontally along the printing width, and curing lamps are installed on the carriages.

[0052] In this embodiment, the irradiation directions of the two carriages and the curing lamps are opposite to each other.

[0053] In other embodiments, the two trolleys are staggered in height.

[0054] In this embodiment, the overall volume of the light-curing module is smaller, but it needs to move with the printing carriage. The moving speed can be freely set and does not need to be fully matched with the high-speed printing carriage, so that the two can operate independently.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
