Description

Technical Field

[0001] This utility model belongs to the technical field of UV curing machines that can prevent ultraviolet leakage, and particularly relates to a UV curing machine that can prevent ultraviolet leakage. Background Technology

[0002] The principle of UV curing is to use ultraviolet light to irradiate special adhesives, causing them to polymerize and thus cure. As a new curing solution, it has the advantages of short curing time, which can significantly improve production efficiency. Compared with traditional oven curing, it is also more environmentally friendly, as it does not produce any toxic substances, making it an ideal adhesive curing solution.

[0003] However, even with UV curing machines that are designed to prevent UV leakage, UV light may still leak from the inlet and outlet during use. The wavelength of the UV light can damage the hands of workers, and excessive UV radiation entering the skin can cause skin cancer and affect human health. Utility Model Content

[0004] In view of the problems existing in the prior art, the main purpose of this utility model is to provide a UV curing machine that can prevent ultraviolet leakage. The provided UV curing machine can effectively prevent ultraviolet leakage and ensure operational safety.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model provides a UV curing machine that can prevent ultraviolet light leakage, the UV curing machine that can prevent ultraviolet light leakage includes:

[0007] A curing chamber, the curing chamber having an inlet and an outlet, and a UV curing lamp located between the inlet and the outlet;

[0008] The curing chamber is equipped with shielding curtain groups at both the inlet and outlet. Each shielding curtain group includes an inner curtain adjacent to the UV curing lamp and an outer curtain away from the UV curing lamp, with a first gap between the two curtains.

[0009] The conveying mechanism includes a conveyor belt that runs through the curing chamber, and a tray containing materials can be input into / out of the curing chamber by the conveyor belt; the length of the tray along its conveying direction is less than the first interval.

[0010] As a further description of the above technical solution, the bottom ends of both the inner and outer curtains are in contact with the conveyor belt.

[0011] As a further description of the above technical solution, both the inner curtain and the outer curtain are made of Teflon fabric.

[0012] As a further description of the above technical solution, both the inner curtain and the outer curtain are of a one-piece structure; or,

[0013] Both the inner and outer curtains include multiple curtain bodies arranged along the width direction of the conveyor belt, with any two adjacent curtain bodies partially overlapping.

[0014] As a further description of the above technical solution, the conveyor belt along the conveying direction of the tray has a segmented structure or an integrated structure.

[0015] As a further description of the above technical solution, the UV ultraviolet curing lamp is fixed to the top of the inner wall of the curing chamber.

[0016] As a further description of the above technical solution, the curing chamber is also provided with a diffuse reflector plate, which is located on both sides of the UV curing lamp in the conveying direction of the tray.

[0017] Based on the above technical solutions, the outstanding effects of this utility model are as follows:

[0018] In the operation of the UV curing machine provided by this utility model, which prevents ultraviolet light leakage, the material placed in the tray is fed into the curing box by a conveyor belt that runs through the curing box. The material is then cured by UV curing lamps located between the inlet and outlet of the curing box, and then output via the conveyor belt. Because shielding curtains are installed at both the inlet and outlet of the curing box, each shielding curtain includes an inner curtain adjacent to the UV curing lamp and an outer curtain away from the UV curing lamp, with a first gap between the two curtains. Simultaneously, the length of the tray along its conveying direction is less than this first gap. Therefore, during the process of the material following the tray in and out of the curing box, the inner and outer curtains of any shielding curtain group will not open simultaneously. This effectively blocks the ultraviolet light emitted by the UV curing lamps, preventing leakage from the inlet or outlet of the curing box and effectively avoiding radiation damage to operators.

The implementation methods of this utility model will now be described based on its overall structure.

[0024] Please see Figure 1 This utility model discloses a UV curing machine that can prevent ultraviolet light leakage, the UV curing machine that can prevent ultraviolet light leakage includes:

[0025] Curing chamber 1, the curing chamber 1 is provided with a feed inlet and a discharge outlet, and a UV ultraviolet curing lamp 2 located between the feed inlet and the discharge outlet;

[0026] The curing chamber 1 is equipped with shielding curtain groups at both the inlet and outlet. Each shielding curtain group includes an inner curtain 3 adjacent to the UV curing lamp 2 and an outer curtain 4 away from the UV curing lamp 2, and there is a first gap between the two curtains.

[0027] The conveying mechanism includes a conveyor belt 5 that runs through the curing chamber 1, and a tray 6 containing materials that can be input to / output from the curing chamber 1 by the conveyor belt 5; the length of the tray 6 along its conveying direction is less than the first interval.

[0028] With the above structure, the material is placed in the tray 6 and fed into the curing chamber 1 by the conveyor belt 5, which runs through the curing chamber 1 and is included in the conveying mechanism. The material is then cured by UV curing lamps 2 located between the inlet and outlet of the curing chamber 1, and then output via the conveyor belt 5. Since both the inlet and outlet of the curing chamber 1 are equipped with shielding curtain groups, each shielding curtain group includes an inner curtain 3 adjacent to the UV curing lamp 2 and an outer curtain 4 away from the UV curing lamp 2, with a first gap between the two curtains. Simultaneously, the length of the tray 6 along its conveying direction is less than the first gap. Therefore, during the process of the material following the tray 6 in and out of the curing chamber 1, the inner curtain 3 and outer curtain 4 in either shielding curtain group will not open simultaneously. This effectively blocks the ultraviolet light emitted by the UV curing lamp 2, preventing it from leaking out of the inlet or outlet of the curing chamber 1 and effectively avoiding radiation damage to the workers.

[0029] Please see Figure 1 Specifically, in this embodiment, the bottom ends of both the inner curtain 3 and the outer curtain 4 are in contact with the conveyor belt 5, thereby effectively preventing the ultraviolet light inside the curing box 1 from leaking out from the bottom of the shielding curtain.

[0030] Specifically, in this embodiment, both the inner curtain 3 and the outer curtain 4 are made of Teflon cloth, which can effectively block ultraviolet rays from leaking out of the curing chamber 1. Of course, in other embodiments, the inner curtain 3 and the outer curtain 4 can also be made of other materials that resist ultraviolet radiation.

[0031] Specifically, in this embodiment, both the inner curtain 3 and the outer curtain 4 are one-piece structures. Of course, in other embodiments, both the inner curtain 3 and the outer curtain 4 may include multiple curtains arranged along the width direction of the conveyor belt 5, with any two adjacent curtains partially overlapping.

[0032] Specifically, in this embodiment, the conveyor belt 5 is an integral structure along the conveying direction of the tray 6. Of course, in other embodiments, the conveyor belt 5 can also be a segmented structure along the conveying direction of the tray 6, for example, divided into an input segment located outside the feed inlet of the curing box 1, an output segment located outside the discharge outlet of the curing box 1, and a curing segment located inside the curing box 1. It should be understood that when the conveyor belt 5 is a segmented structure, the gap between two adjacent segments is not sufficient to cause material jamming on the tray 6, and it can still be conveyed smoothly.

[0033] Specifically, in this embodiment, the UV curing lamp 2 is fixed to the top of the inner wall of the curing chamber 1. It can emit strong ultraviolet rays to irradiate the surface of the material passing below it, so that the surface coating can be cured by light.

[0034] Specifically, in this embodiment, the curing chamber 1 is further provided with a diffuse reflector 7. The purpose of providing the diffuse reflector 7 is to allow some ultraviolet rays to be refracted onto the material to be cured through the diffuse reflector 7, thereby reducing the waste of light resources caused by ultraviolet scattering. In the conveying direction of the tray 6, the diffuse reflector 7 is located on both sides of the UV curing lamp 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any changes, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
