DETAILED DESCRIPTION

[0023] The utility model will be described in detail below through examples, which are only used for further illustrating the utility model and cannot be understood as limiting the protection scope of the utility model.

[0024] As shown in Figure 1 — Figure 5 The embodiment provides a modularized spliced ink pre-curing structure, which is mainly used for pre-curing or auxiliary curing of ink on the surface of a printing material on a printing production line and adopts an LED ultraviolet light source.

[0025] Overall structure and modularized splicing: the pre-curing structure comprises three (the number can be increased or decreased according to needs) standard module assemblies 1 that can be spliced with each other. When the module assemblies 1 are spliced along a straight line, end plates 2 are installed at both ends to form a complete pre-curing unit with adjustable length.

[0026] Structure of a single module assembly 1 (see Figure 3 ): each module assembly 1 mainly comprises a cooling cavity 3, a base plate 4, a column lens 5, a side plate 6 and a top plate 7.

[0027] Cooling cavity 3 and base plate 4: the cooling cavity 3 is preferably made of a metal material (such as an aluminum alloy) with good heat conduction performance, and a cooling channel 12 with a circular cross section is formed in the cooling cavity 3 along the length direction. The base plate 4 (usually a PCB circuit board or a metal base plate) is attached to the top surface of the cooling cavity 3 and is fixedly connected to the cooling cavity 3 through a plurality of fasteners (such as countersunk screws), so that heat on the base plate 4 can be effectively conducted to the cooling cavity 3.

[0028] LED lamp 8: a plurality of LED lamps 8 (such as UV LED lamp beads) are arranged and welded on the base plate 4 along the length direction of the cooling cavity 3 according to design requirements, and the ultraviolet rays emitted by the LED lamps 8 are used for curing ink.

[0029] Side plates 6 and supporting plates: There are two side plates 6, which are arranged on both sides of the cooling cavity 3 in the width direction. The upper and lower edges of each side plate 6 are bent by 90° to form an upper supporting plate 61 above and a lower supporting plate 62 below.

[0030] Cylindrical lens 5 and positioning block assembly 9: The cylindrical lens 5 is arranged below the LED lamp 8, which converges or integrates the point or divergent light emitted by the LED lamp 8 into a linear light spot with a certain shape to improve the curing efficiency and uniformity. Corresponding to each cylindrical lens 5 (or one or more cylindrical lenses 5 corresponding to a group of LED lamps 8, and in this embodiment, one cylindrical lens 5 corresponding to the LED lamp group below is taken as an example), a positioning block assembly 9 is arranged at both ends thereof. The positioning block assembly 9 includes two symmetrically arranged positioning blocks 10 (as shown in Figure 2 Each positioning block 10 is machined with an arc-shaped positioning groove 11 that matches the shape of the outer peripheral wall of the cylindrical lens 5, so as to prevent the cylindrical lens 5 from rolling and ensure that the axis thereof is coaxial with the optical axis of the LED lamp 8 or forms a preset angle. The positioning block 10 is fixedly connected to the lower supporting plate 62 of the side plate 6 through the mounting hole thereon by using a fastener. The spacing space between the lower supporting plates 62 of the two side plates 6 forms the ultraviolet light irradiation area 25 for the cylindrical lens 5, and the printing material will be irradiated from below or the side of the irradiation area 25.

[0031] Top plate 7: The upper supporting plate 61 of the side plate 6 is fixedly connected to the top plate 7 by a fastener, and the top plate 7 covers the substrate 4 above to play a protective and dustproof role, and also enhances the overall rigidity of the module assembly 1.

[0032] Splicing and sealing of the cooling channel: In order to realize the communication of the cooling channels 12 of multiple module assemblies 1, a continuous cooling loop is formed:

[0033] The cooling cavity 3 is machined with a sealing groove 13 at the outlet end (for example, the right end assuming that the cooling liquid flows from left to right) of the cooling channel 12, and an annular insertion pipe 15 is integrally formed or fixedly connected at the port of the cooling channel 12. A sealing ring 16 (such as an O-ring) is arranged between the insertion pipe 15 and the sealing groove 13.

[0034] The cooling cavity 3 is machined with a counter-insertion groove 14 at the inlet end (for example, the left end) of the cooling channel 12, which is also circular and matches and counter-inserts the insertion pipe 15.

[0035] When two module assemblies 1 are spliced, the spigot 15 on the cooling cavity 3 of the right module assembly 1 is inserted into the counter socket 14 of the cooling cavity 3 of the left module assembly 1. At this time, after the spigot 15 is inserted into place, the sealing ring 16 in the sealing groove 13 provides a sealing gap function to prevent leakage of the cooling liquid, and the cooling cavities are attached after being connected by screws to form a whole, realizing good sealing of the cooling channel 12 at the splicing position and preventing leakage of the cooling liquid. The side plate 6 is connected to the corresponding position on the side of the cooling cavity 3 by a fastener.

[0036] Connection between modules and peripheral plate: In two adjacent module assemblies 1, the two side plates 6 adjacent to each other are not directly connected, but are connected to a common peripheral plate 18 (the number of peripheral plates 18 is set according to needs, for example, one on each side of the splicing structure) by their respective fasteners. This design makes the splicing of the module assembly 1 more regular, the overall structural strength higher, and it is also convenient to install uniformly on the printing equipment.

[0037] End plate and sealing structure: The end plate 2 located at both ends of the entire splicing structure is provided with a sealing structure 19 (for example, it can be a plug or cover plate matched with the inner diameter of the cooling channel 12). The end plate 2 is fixedly connected to the cooling cavity 3 of the outermost module assembly 1 by a fastener, and its sealing structure 19 extends into and seals the inlet and outlet ends of the cooling channel 12, ensuring that the cooling liquid does not leak from the end.

[0038] Water connection: One end (for example, the left end of the leftmost module assembly 1) of the cooling cavity 3 is machined with a water outlet 20 for inserting a water outlet pipe 21; the other end (for example, the right end of the rightmost module assembly 1) is machined with a water outlet 20 for inserting a water inlet pipe 22. However, for safety or standardized production, the plugs 23 can also be provided at these intermediate water outlets 20 for sealing, or only the water outlets 20 can be provided on the two end module assemblies 1 during design, and the intermediate modules are not provided or can be sealed. The cooling liquid (such as water or special cooling liquid) enters the cooling channel 12 of the rightmost module assembly 1 from the water inlet pipe 22, flows through the cooling channels 12 of each spliced module in turn, and finally flows out from the cooling channel 12 of the leftmost module assembly 1 through the water outlet pipe 21, taking away the heat generated by the LED lamp 8 and the substrate 4.

[0039] Work flow: according to the solidification length required by the customer, select the corresponding number of module assemblies 1. Arrange the module assemblies 1 in a straight line, and sequentially splice: insert the insertion tube 15 of the right module into the insertion slot 14 of the left module, and ensure that the sealing ring is in place; use fasteners to fix the adjacent side plates 6 to the peripheral plates 18; connect the end plates 2 at both ends and block the cooling channels 12. Then, insert the water inlet pipe 22 into the water inlet 20 of the rightmost module assembly 1, and insert the water outlet pipe 21 into the water inlet 20 of the leftmost module assembly 1, and use the plug 23 to block the water inlets 20 of the intermediate modules. Turn on the power supply of the LED lamp 8 and the cooling liquid circulating pump, and the printing material passing through can be inked.

[0040] The above merely describes the preferred embodiments of the present application, and is not intended to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
