Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting label processing, in particular to a pre-curing developing device for sunlight-sensitive color-changing ink. Background Technique

[0002] The color-changing principle of sunlight-sensitive color-changing ink is mainly based on the photosensitive color-changing effect, which is caused by the molecular structure change after the dye molecules in the ink absorb light. Specifically, the dyes with photosensitive color-changing functions are mainly composed of heterocyclic molecular structures. Such dyes with heterocyclic molecular structures can undergo reversible changes when exposed to ultraviolet light. When the molecules are in a closed loop, the dyes appear colorless; after being irradiated by ultraviolet light, the molecules open the loop and turn into another structure, showing blue or other colors; when the dyes leave the ultraviolet light, they turn back into the original colorless state again. This change process is reversible, so it is called the "photochromic" phenomenon. Moreover, the ultraviolet lamp can not only play the role of developing, but also has the effect of curing and consolidating the ink.

[0003] In order to improve the anti-counterfeiting effect, the existing anti-counterfeiting labels are often coated with a layer of sunlight-sensitive color-changing ink. However, in the existing technology, after the ink is coated, it is cured by traditional heat drying technology and then developed and inspected by irradiating with ultraviolet light. However, the ink after heat drying is not completely cured, and in order to improve the developing inspection, the existing ultraviolet light is widely dispersed, so that its original curing effect is gradually reduced to a stage where it cannot be utilized. Therefore, we propose a device that can reasonably utilize ultraviolet light. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Referring to the attached Figures 1-4 , a daylight color-changing ink pre-curing and developing device includes an ultraviolet lamp box 2 installed on a frame body 1. The ultraviolet lamp box 2 includes a plurality of bulbs 3 evenly distributed at equal intervals, and a light control device 4 is arranged between a plurality of bulbs 3 in the same column;

[0019] The light control device 4 includes two light shielding plates 41 fixed to the bottom of the ultraviolet lamp box 2. The two light shielding plates 41 are symmetrically arranged and are respectively located on both sides of the bulb 3. A number of Fresnel lenses 42 located below the bulb 3 are fixedly installed between the two light shielding plates 41. The position of the Fresnel lens 42 corresponds to the position of the bulb 3. An operation plate 43 is slidably installed at the bottom of one of the light shielding plates 41. A number of concave lenses 44 corresponding to the positions of the respective Fresnel lenses 42 are installed on the operation plate 43. The concave lens 44 is located below the Fresnel lens 42.

[0020] During operation, after the film plate stamped with the daylight color-changing ink is preliminarily cured by an external drying device, the film plate is located below the ultraviolet lamp box 2 on the frame 1. By starting the ultraviolet lamp box 2, the bulb 3 emits ultraviolet light. When it is necessary to cure the daylight color-changing ink, the light will be concentrated by the Fresnel lens 42 and directly irradiated on the film plate. In this way, compared with the dispersed light, the light concentration is improved, so the curing ability is improved and the curing time is accelerated.

[0021] When it is necessary to inspect the daylight color-changing ink stamped on the film plate, by moving the operation plate 43, the concave lens 44 is located below the Fresnel lens 42. Thus, the concave lens 44 can disperse the concentrated light, so that the light is irradiated on the film plate in a large area. The dye molecules in the ink absorb light and cause changes in the molecular structure. The dye with a heterocyclic molecular structure can undergo reversible changes when exposed to ultraviolet light. The molecule opens the ring and becomes another structure, presenting blue or other colors. Thus, the staff can clearly check whether the stamped information meets the requirements.

[0022] Through this setting, the ultraviolet light can be concentrated under the action of the Fresnel lens 42, so that the curing effect can be improved. And then by moving the concave lens 44 under the Fresnel lens 42 to disperse the concentrated light, it can be checked whether the information after stamping meets the requirements. Therefore, this device has both the effects of curing and developing inspection at the same time, and the operation is simple and the use effect is good.

[0023] In this embodiment, auxiliary components 5 are respectively provided on both sides of the bulb 3 and fixed to the light shielding plate 41. The auxiliary component 5 includes a convex lens 51 on the side of the bulb 3 and a refractive mirror 52 located below the convex lens 51.

[0024] When the bulb 3 emits light, since there is a certain distance between it and the Fresnel lens 42, it is impossible to ensure that all the light rays are concentrated on the Fresnel lens 42. At this time, the scattered light rays will be concentrated by the convex lens 51, and the light rays concentrated by the convex lens 51 will irradiate on the refracting mirror 52. Through the refracting mirror 52, the concentrated light rays can be refracted onto the Fresnel lens 42, so that the light rays that should have dissipated can be concentrated on the Fresnel lens 42 and used as curing light rays, thereby further improving the curing effect.

[0025] It should also be noted that sliding grooves 6 are opened on both sides of the bottom of the light-shielding plate 41 located on the outside, and sliding blocks slidably installed in the sliding grooves 6 are fixed on both sides of the operation plate 43.

[0026] The concave lens 44 is fixed on the side of the operation plate 43 close to the bulb 3, and a square magnifying glass 45 is fixed on the side of the operation plate 43 far from the bulb 3.

[0027] Thus, through this setting, when developing and inspecting through the concave lens 44, the developed ink can be magnified through the operation plate 43, so it is convenient for the staff to inspect.

[0028] In addition, electric sliding tables 7 are fixedly installed on both sides of the frame body 1, a sliding seat 8 is provided on the electric sliding table 7, and the ultraviolet lamp box 2 is fixedly connected to the sliding seat 8, so that it can move automatically.
