Technical Field

[0001] This utility model belongs to the field of ultraviolet curing technology, specifically a ventilation device for a microwave ultraviolet curing system. Background Technology

[0002] In the printing industry, the use of ultraviolet light for curing is very common. When ultraviolet light is irradiated, it generates some heat. Generally, in order to ensure that the ultraviolet light source can be used continuously for a long time, a ventilation device is set up to dissipate heat from the ultraviolet light source, and the ventilation device blows the heat directly into the outside air. In the process of researching ultraviolet curing systems, the inventors discovered that heating the ink during the curing process can accelerate the curing process. Therefore, this application proposes a ventilation device for a microwave ultraviolet curing system. Utility Model Content

[0004] Preferably, the lower end of the air duct is fixedly connected to a first side plate and a second side plate, the second side plate is located on the feeding side, and the first side plate, the second side plate and the side wall of the reflector all have gaps.

[0005] Preferably, a guide plate is fixed to the end of the first side plate, and the guide plate is inclined downward and extends in the direction of feeding.

[0006] Preferably, a connecting bolt is threaded onto the outer casing, and a connecting seat is fixed to the outer wall of the air duct. One end of the connecting bolt is inserted into the connecting seat, and the connecting bolt can rotate within the connecting seat.

[0007] Preferably, a guide rail is also fixed inside the outer casing, and the guide rail is clamped on the outer wall of the air duct.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] When the device is in use, a fan blows air into the air duct, and the air blows through the air duct onto the reflector, thereby blowing away the heat of the reflector to cool the ultraviolet light source. This air is also heated by the ultraviolet light source and blown onto the ink, thereby accelerating the curing of the ink. The hot air can also be blown towards the feed end, thereby accelerating the heating of the ink and speeding up the curing time. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Depend on Figure 1 The present invention discloses a ventilation device for a microwave ultraviolet curing system, including a housing 1, an air duct 4 inside the housing 1, an ultraviolet light source 2 inside the housing 1, a reflector 3 outside the ultraviolet light source 2, the reflector 3 being curved and having its opening facing downwards, the air duct 4 being located outside the reflector 3, and the air inside the air duct 4 blowing from top to bottom.

[0015] When the device is in use, a fan blows air into the air duct 4, and the air blows through the air duct 4 onto the reflector 3, thereby blowing away the heat of the reflector 3 to cool the ultraviolet light source 2. This air is also heated by the ultraviolet light source 2 and blown onto the ink, thereby accelerating the curing of the ink. The hot air can also be blown towards the feed end, thereby accelerating the heating of the ink and speeding up the curing time.

[0016] The lower end of the air duct 4 is fixedly connected to a first side plate 5 and a second side plate 7. The second side plate 7 is located on the side of the feed. The first side plate 5, the second side plate 7 and the side wall of the reflector 3 all have gaps, and the air can blow through the gaps to blow away the heat on the reflector 3.

[0017] A guide plate 6 is fixed to the end of the first side plate 5. The guide plate 6 is inclined downward and extends in the direction of feeding. When the air blows onto the guide plate 6, it can be blown along the guide plate 6, thereby causing the hot air to blow towards the feeding end, that is, blow past the ultraviolet light source 2, so as to accelerate the curing operation.

[0018] A connecting bolt 8 is threaded onto the outer casing 1, and a connecting seat 9 is fixed to the outer wall of the air duct 4. One end of the connecting bolt 8 is inserted into the connecting seat 9, and the connecting bolt 8 can rotate within the connecting seat 9. By rotating the connecting bolt 8, the position of the air duct 4 can be changed to change the air volume blown onto the guide plate 6, thereby accelerating the ultraviolet curing operation.

[0019] A guide rail 10 is also fixed inside the outer casing 1. The guide rail 10 is engaged with the outer wall of the air duct 4, thereby restricting the movement direction of the air duct 4. A slot is provided on the outer wall of the air duct 4 (not shown in the figure; the guide rail 10 is located in the slot and can slide).
