Abstract

An air cooling shutter type ultraviolet (UV) lamp comprises a lampshade body with an upper opening, a UV lamp tube and a curved-surface-shaped reflective board. The UV lamp tube is installed in the lampshade body, and the curved-surface-shaped reflective board is arranged on the lower portion of the UV lamp tube and is divided into a left curved-surface-shaped reflective board and a right curved-surface-shaped reflective board. The air cooling shutter type UV lamp further comprises a pneumatic cylinder, transmission gears, a pivot base and rotating shafts. Two ends of the left curved-surface-shaped reflective board and the right curved-surface-shaped reflective board are fixedly connected with the rotating shafts, the transmission gears are respectively arranged on a pair of the rotating shafts, the pair of the rotating shafts are opposite in the direction of length, a piston rod of the pneumatic cylinder penetrates through an inlet and an outlet, and gear racks on the piston are matched with driven gears to drive. By adopting such a structure, when a printing machine is running, the left curved-surface-shaped reflective board and the right curved-surface-shaped reflective board constitute a reflective cover with the upper opening, and then lights of the UV lamp are emitted from the lampshade body with the upper opening; when the printing machine suddenly starts to run, the pneumatic cylinder motions, and the left curved-surface-shaped reflective board and the right curved-surface-shaped reflective board are reversed to constitute a shading cover with a lower opening, and therefore emission of the lights of the UV lamp from the lampshade body is prevented. The air cooling shutter type UV lamp is convenient to use.

Description

A kind of air-cooled fast gate-type ultraviolet lamp

Technical field

The utility model relates to the UV-device that uses on a kind of printing equipment, especially a kind of air-cooled ultraviolet lamp.

Background technology

Present prior art, the phenomenon of deficiency below the existing ultraviolet lamp, ubiquity, the lampshade volume is excessive, the easy deformation of reflecting shade body, the exhausting radiating effect is not good, and the reflecting shade body temperature is high, causes the UV lamp works life-span short, so influences normal print production.Especially under the unexpected out-of-work situation of printing machinery, ultraviolet lamp still shines, and printing equipment is worked the mischief.

Summary of the invention

The purpose of the utility model is: a kind of air-cooled fast gate-type ultraviolet lamp is provided; It can the unexpected out-of-work situation of printing machinery under; The actuation of reflecting shade body airbrasive, reflecting shade body prevent that the illumination of UV fluorescent tube is mapped to printing machinery, prevent that the printing equipment is undermined.

The utility model is achieved in that a kind of air-cooled fast gate-type ultraviolet lamp; It comprises lampshade, UV fluorescent tube and the curved reflector of upper shed; The UV fluorescent tube is installed in the lampshade; Said curved reflector is arranged on the bottom of UV fluorescent tube, and its special character is: said curved reflector is divided into left curved reflector and right curved reflector

Several heat radiation steam vents are arranged on the base plate of the lampshade of said upper shed, and an end has import and export;

Also comprise a cylinder, travelling gear, pin joint seat and rotating shaft,

Pin joint seat is arranged on the two ends of lampshade, and the end plate of rotating shaft and pin joint seat and lampshade articulates; The two ends of said left and right curved reflector are fixedly connected with rotating shaft;

Travelling gear has two, is separately positioned on the relative countershaft of length direction, and the both sides of the piston rod of said cylinder are provided with tooth bar, and piston rod passes import and export, and the tooth bar on the piston rod cooperates transmission with driven gear.

Described a kind of air-cooled fast gate-type ultraviolet lamp; Its special character is: on the inwall of the lampshade of said upper shed gathering sill is arranged; Also comprise the cover plate of two band air-vents, said cover plate is arranged on the two ends of lampshade, and cover plate covers the end of pin joint seat to lampshade.

Described a kind of air-cooled fast gate-type ultraviolet lamp, its special character is: also comprise the drain pan of a upper shed, on the base plate of drain pan the inlet scoop is arranged; Said drain pan is arranged on the bottom of lampshade, and drain pan supports lampshade, and drain pan and lampshade are fixed together.

Described a kind of air-cooled fast gate-type ultraviolet lamp, its special character is: said lampshade and drain pan both ends open also comprise two end casings;

End casing is screwed with the drain pan two ends with lampshade and is connected.

A kind of air-cooled fast gate-type ultraviolet lamp of the utility model, owing to adopt such structure, when printing machinery was worked, left and right curved reflector constituted the reflection shield of upper shed, the light of the lamp of UV fluorescent tube penetrates from the lampshade of upper shed at this moment; When printing machinery is worked suddenly, the cylinder action, thus the counter-rotating of left and right curved reflector constitutes the light shield of under shed, prevents that the light of UV fluorescent tube from penetrating from lampshade.Easy to use.

Fig. 2 is the vertical view of the utility model.

Fig. 3 is that this calamity is with novel right view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1; A kind of air-cooled fast gate-type ultraviolet lamp; It comprises lampshade 1, UV fluorescent tube 2 and the curved reflector of upper shed, and UV fluorescent tube 2 is installed in the lampshade 1, and said curved reflector is arranged on the bottom of UV fluorescent tube 2; Said curved reflector is divided into left curved reflector 31 and right curved reflector 32

On the base plate of the lampshade 1 of said upper shed several louvres are arranged, an end has import and export;

Also comprise a cylinder 4, driven gear 5, pin joint seat 6 and rotating shaft 7,

Pin joint seat 6 is arranged on the two ends of lampshade 1, and rotating shaft 7 articulates with the end plate of pin joint seat 6 and lampshade 1; The two ends of said left and right curved reflector 31,32 are fixedly connected with rotating shaft 7;

Driven gear 5 has two, is separately positioned on the relative countershaft 7 of length direction, and the both sides of the piston rod 41 of said cylinder 4 are provided with tooth bar, and piston rod 41 passes import and export, and the tooth bar on the piston rod 41 cooperates transmission with driven gear 5.

On the inwall of the lampshade 1 of said upper shed gathering sill is arranged, also comprise the cover plate 8 of two band heat radiation steam vents, said cover plate 8 is arranged on the two ends of lampshade 1, and cover plate 8 covers the end of pin joint seat 6 to lampshade 1.
