[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] like Figure 1 As shown, the present application provides a UV curing device for curing carton boards, comprising a curing box 1, wherein a plurality of curing lamps 12 are arranged in the curing box 1, wherein the curing lamps 12 are semiconductor light emitting devices of ultraviolet light in the prior art, and a support portion 4 is fixedly mounted at the lower end of the curing box 1, and the curing box 1 is supported by the support portion 4;

[0036] A curing chamber (not shown in the figure) is provided in the curing box 1, one end of which passes through one side of the curing box 1, and a box door 13 is rotatably connected to the port of the curing chamber. By opening the box door 13, the curing lamp 12 can be conveniently installed in the curing box 1. At the same time, channels 11 are provided on both sides of the lower end of the curing box 1, and a conveyor belt 5 is provided in the channel 11. The conveyor belt 5 is used to convey the carton board to be cured. The conveyor belt 5 is a prior art, and the conveyor belt 5 is also fixed on the support part 4.

[0037] like Figure 2-Figure 3 As shown, in order to facilitate the disassembly and replacement of multiple groups of curing lamps 12 as a whole, a fixed cover 2 is provided in the curing box 1, and the fixed cover 2 has extension plates 21 located on both sides thereof and facing downward, and a fixed plate 22 is fixedly installed between the extension plates 21. At the same time, a sliding sleeve 3 is installed above the curing lamp 12, and the sliding sleeve 3 is sleeved on the fixed plate 22. Therefore, multiple groups of curing lamps 12 are installed in the fixed cover 2 through the sliding sleeve 3 to form an integrated irradiation structure, and the curing lamp 12 can be slid on the fixed plate 22 through the sliding sleeve 3 to select the irradiation position of the curing lamp 12.

[0038] A fixing strip 23 is fixedly installed on the outer side of the extension plate 21, and mounting grooves 14 are provided on both sides of the interior of the curing box 1. The mounting grooves 14 and the fixing strips 23 cooperate with each other. Therefore, during installation, the fixing strips 23 on both sides of the fixing cover 2 are inserted into the mounting grooves 14, so that the fixing cover 2 is installed inside the curing box 1.

[0039] At the same time, a fixing hole (not shown in the figure) is opened on the baffle between the mounting grooves 14, and a fixing bolt is arranged in the fixing hole. Therefore, after the fixing strip 23 is installed in the mounting groove 14, the fixing bolt is tightened to fix the curing lamp 12;

[0040] In the present application, the mounting grooves 14 are provided in multiple groups along the height direction, and the multiple groups of mounting grooves 14 are evenly opened on both sides of the interior of the curing box 1. Therefore, the operator can select mounting grooves 14 of different heights according to the thickness of the required curing carton board, and fix the fixing cover 2 and the curing lamp 12, thereby preventing the curing lamp 12 from being too low or too high to achieve a curing effect.

[0041] In order to facilitate the replacement of the curing lamp 12 separately, a mounting plate 31 is fixedly installed at the lower end of the sliding sleeve 3. Two groups of holes 32 are opened on the mounting plate 31. The two groups of holes 32 are located on both sides of the sliding sleeve 3. At the same time, a threaded hole 121 is opened at the top of the curing lamp 12. The threaded hole 121 corresponds to the hole 32. The second bolt 33 is connected to the thread in the threaded hole 121. Therefore, when installing, the second bolt 33 is passed through the hole 32 and then screwed into the threaded hole 121, so as to fix the curing lamp 12 and the sliding sleeve 3. When disassembling, only the second bolt 33 needs to be screwed out.

[0042] Meanwhile, a mounting hole 34 is provided on one side of the sliding sleeve 3 , and a first bolt 35 is threadedly connected to the mounting hole 34 . The sliding sleeve 3 can be fixed to the fixing plate 22 by tightening the first bolt 35 , thereby preventing the curing lamp 12 from shaking.

[0043] A handle 24 is fixedly mounted on one end of the fixed cover 2 close to the box door 13 , and the handle 24 facilitates the entire fixed cover 2 to be pulled out and pushed in. In addition, the handle 24 does not protrude from the curing box 1 under normal conditions, and thus does not affect the opening and closing of the box door 13 .

[0044] To sum up: if the position of the curing lamp 12 needs to be adjusted, the fixing cover 2 is pulled out as a whole through the handle 24, and the installation grooves 14 of different heights are selected according to the thickness of the carton board, and then the fixing cover 2 is inserted into the selected installation groove 14, so as to quickly adjust the irradiation position of the curing lamp 12, prevent the problem of incomplete or uneven curing of carton boards with different thicknesses by the lamp tube assembly, thereby ensuring the curing efficiency.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. 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.
