The utility model discloses a kind of UV lamp shutter, overcome in the prior art, many defects that UV lamp shutter still suffers from.The utility model contains two side plates, guide rod, power transmission shaft, drives, it is parallel between two side plates to be provided with more guide rods, driving wheel tube is connected on power transmission shaft, and the outermost of the drive and guide rod is tangent to be fitted and connected darkening ring, and loophole is provided with darkening ring.The darkening ring is ring-type tubular circle, and its both ends ring-type is equidistant to be provided with driving hole, and drive is provided with driving cog, passes through driving hole and driving cog engagement connection between darkening ring and drive.Engaging connection by driving hole and driving cog between darkening ring and drive can ensure that ultraviolet will not be exposed, to strengthen the radiating effect of fluorescent tube, the service life of prolonging lamp tube；Darkening ring is made up of flexible seamless steel ring, and in both sides, the equidistant driving hole of circle of processing two, accurate to control darkening ring movement position for transmission and rolling counters forward.
Description
Technical field
The utility model is related to the exposure machine equipment in a kind of printing machine, more particularly to a kind of UV lamp shutter.
Background technology
Exposure machine refers to the ultraviolet that UV-A wavelength is sent by opening light, by the image on film or other transparent bodies
Information is transferred to the equipment on the surface for scribbling photoactive substance.UV lamp, UV digital printings are typically provided with exposure machine equipment
When machine uses mercury lamp as curing light source, a shutter is installed typically inside UV lamp, shutter, UV are opened in print procedure
Light irradiation print media makes ink fixed line, and shutter is closed when not printing, and avoids print media by roasting deformation.Existing UV lamp shutter one
As the opening and closing of shutter is realized using moving seesaw-type side opening structure or lever construction, due in design there is it is larger the defects of, make
UV lamp life-span it is shorter, and the inconvenience that operates easily makes ultraviolet exposed.
Utility model content
The utility model overcomes in the prior art, many defects that UV lamp shutter still suffers from, there is provided it is a kind of it is simple in construction,
UV lamp shutter safe and convenient to use.
Technical solution of the present utility model is to provide a kind of UV lamp shutter with following structure：Contain two sides
Plate, guide rod, power transmission shaft, drive, parallel between two side plates to be provided with more guide rods, driving wheel tube is connected on power transmission shaft,
The outermost of the drive and guide rod is tangent to be fitted and connected darkening ring, and loophole is provided with darkening ring.
Preferably, multiple loopholes are provided with the darkening ring, the wherein quantity of loophole is 3-6, the shape of loophole
Shape is rectangle.
Preferably, the darkening ring is ring-type tubular circle, and its both ends ring-type is equidistant to be provided with driving hole, and drive is provided with
Driving cog, pass through driving hole and driving cog engagement connection between darkening ring and drive.
Preferably, the darkening ring is seamless steel ring or seamless rubber circle.
Preferably, the quantity of the guide rod is 2,4 or 6.
Preferably, the quantity of the drive is 2, the driving hole being socketed in respectively on the both ends and darkening ring of power transmission shaft
Engagement connection, the output shaft of one end connection transmission device of power transmission shaft.
Preferably, the transmission device is motor and reductor.
Preferably, the driving hole be shaped as it is square or circular.
Compared with prior art, the utility model UV lamp shutter has advantages below：1st, it is simple in construction, operate steadily, easily
In maintenance；2nd, process, assemble simply, cost is low；3rd, take up space small, it is in light weight, to the requirement of UV digital-code printers integral-rack
It is low；4th, engaging connection by driving hole and driving cog between darkening ring and drive can ensure that ultraviolet will not be exposed, to increase
The radiating effect of strong fluorescent tube, the service life of prolonging lamp tube；5 motors (or air motor) start without frequent rotating, keep
One direction, which rotates, can be achieved shutter opening and closing；6th, darkening ring is made up of flexible seamless steel ring, the circle of processing two in both sides
Equidistant driving hole, on the one hand it is used to be driven, it is accurate to control darkening ring movement position on the other hand suitable for rolling counters forward.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram that the utility model UV lamp shutter does not install darkening ring；
Fig. 2 is the dimensional structure diagram of darkening ring in the utility model UV lamp shutter；
Fig. 3 is the structural representation of the utility model UV lamp shutter installation darkening ring；
Fig. 4 is the side structure schematic diagram of the utility model UV lamp shutter.
Embodiment
Label 1 is side plate in brief description of the drawings, and 2 be guide rod, and 3 be power transmission shaft, and 4 be drive, and 5 be UV lamp, and 6 be shading
Circle, 7 be reflection shield, and 8 be driving hole, and 9 be loophole.
The shutter of the utility model UV lamp 5 is described further with reference to the accompanying drawings and detailed description：As illustrated,
It is parallel between two side plates 1 to be provided with more guiding containing two side plates 1, guide rod 2, power transmission shaft 3, drive 4 in the present embodiment
Bar 2, drive 4 are socketed on power transmission shaft 3, and the outermost of the drive 4 and guide rod 2 is tangent to be fitted and connected darkening ring 6,
Loophole 9 is provided with darkening ring 6.
Multiple loopholes 9 are provided with the darkening ring 6, the wherein quantity of loophole 9 is 3-6, and loophole 9 is shaped as
Rectangle or round rectangle.
The darkening ring 6 is ring-type tubular circle, and its both ends ring-type is equidistant to be provided with driving hole 8, and drive 4 is provided with transmission
Tooth, pass through driving hole 8 and driving cog engagement connection between darkening ring 6 and drive 4.
The darkening ring 6 is seamless steel ring or seamless rubber circle.
The quantity of the guide rod 2 is 2,4 or 6.Guide rod 2 plays guide effect during 6 circular motion of darkening ring,
It is the important support part of total, quantity selection 4 is proper.
