Description

The ultraviolet drier shutter device

The utility model relates to a kind of ultraviolet drier shutter device.

Present ultraviolet drier shutter device, because the limited relation of light excluding shutter (being shutter) structure, therefore quite huge the causing of volume of whole device takes up room, and the unlatching of shutter, closing motion are slow, price is higher; But because of this shutter device is to utilize the transmission of rack drives fan type tooth piece to open or close shutter to reach, so tooth bar and tooth piece have clearance issues and produce, therefore cause the shutter plate closure bad, ultraviolet ray still can be by penetrating between the slit, causes illuminated object temperature too high and the possibility of burning arranged.

The purpose of this utility model is to provide a kind of shutter that can make can open and close driving fit fully, makes the unlikely illuminated object quality of influence that exposes of ultraviolet ray to improve the ultraviolet drier shutter device of the security of personnel and workplace simultaneously.

The purpose of this utility model is achieved in that this shutter device is that shutter plate with two suitable bent arc shapes runs through setting by axostylus axostyle respectively in the outer rim place, the centre of two door-plates then has a ultraviolet light fixture, other is each establish and be meshing with each other first gear and second gear in the protruding end of two axostylus axostyles, one side, the front end of first gear driven sprocket that then is coupling, shutter device is to have CD-ROM drive motor in a suitable side, at the CD-ROM drive motor rotating shaft place drive sprocket that is pivoted, drive sprocket is then with the driven sprocket on the chain engages axostylus axostyle, in addition, shutter device is provided with first shifting block and second shifting block in the side protruding end in addition of a suitable axostylus axostyle with predetermined angle, and first, the below of second shifting block then is provided with first microswitch and second microswitch respectively; When CD-ROM drive motor is subjected to instruction to drive the driving member rotation, this two axostylus axostyle is rotation and the start of drive shutter plate thereupon just, be positioned at axostylus axostyle in addition side first, second shifting block then according to direction of rotation out of the ordinary touch first or second microswitch after, drive the instruction that sets immediately and make CD-ROM drive motor be rotation forward or backwards, make shutter plate implement to open or closing motion with this according to the direction that is moved.

The utility model has following advantage compared to existing technology: the shortcoming that not only can effectively solve existing device, can effectively improve the deficiency of traditional shutter device, can make shutter can open and close driving fit fully again, make unlikely the exposing of ultraviolet ray influence illuminated object quality, improve the security of personnel and workplace simultaneously.

The drawing of accompanying drawing is described as follows:

Fig. 3 is an outward appearance rear perspective schematic diagram of the present utility model,

Fig. 4 is a shutter opening action schematic perspective view of the present utility model,

Fig. 5 is a shutter close action schematic perspective view of the present utility model.

Below in conjunction with drawings and Examples the utility model is described in further detail: UV curing board 1, outer cover 11, first shifting block 15, lampshade 212, shutter device 2, axostylus axostyle 23, second shifting block 26, wind-collecting cover 211, ultraviolet light fixture 20, shutter plate 22, CD-ROM drive motor 24, inner cover the 21, the 1st gear 231, driven sprocket the 233, the 1st microswitch the 251, the 2nd gear 232, drive sprocket the 241, the 2nd microswitch 261, chain 242.

As shown in figures 1 and 3, the utility model mainly is to have an outer cover 11 above UV curing board 1, be provided with shutter device 2 and be positioned at outer cover 11 inside, the top of this shutter device 2 is provided with inner cover 21 in addition, and 21 of inner covers include the wind-collecting cover 211 on top and the lampshade 212 of bottom.

As Fig. 2 and shown in Figure 4, shutter device 2 of the present utility model is that the shutter plate 22 with two suitable bent arc shapes runs through setting by axostylus axostyle 23 respectively in the outer rim place, the centre of two shutter plates 22 then has a ultraviolet light fixture 20, in addition be convexly equipped with each first gear 231 of establishing and be meshing with each other of end, and the front end of second gear, 232, the first gears 231 driven sprocket 233 that then is coupling in two axostylus axostyles, 23 1 sides; Shutter device 2 is to have CD-ROM drive motor 24 in a suitable side, at the CD-ROM drive motor 24 rotating shafts place drive sprocket 241 that is pivoted, drive sprocket 241 is then with the driven sprocket 233 on the chain 242 engagement axostylus axostyles 23, in addition, shutter device 2 is provided with first shifting block 25 and second shifting block 26 in a suitable axostylus axostyle 23 other ends that are convexly equipped with of side with the predetermined angle axle, and the below of first shifting block 25 is provided with first microswitch 251, and the below of second shifting block 26 then is provided with second microswitch 261 in addition.261 startup sources of first microswitch 251 and second microswitch as motor control circuit.

As Fig. 2 and shown in Figure 5, combination by above-mentioned member, when shutter device 2 of the present utility model is subjected to instruction to drive the driving member rotation at CD-ROM drive motor 24, this two axostylus axostyle 23 is rotation and drive 22 starts of two shutter plates respectively thereupon just, and be positioned at axostylus axostyle 23 in addition first shifting block 25 (or second shifting block 26) of sides after touching first microswitch 251 (or second microswitch 261), the instruction that driving immediately sets is CD-ROM drive motor 24 and is rotated in the forward, the shutter plate 22 then positive veer that moved of foundation two axostylus axostyles 23 is implemented breakdown action, makes the processed object of ultraviolet light fixture 20 irradiations process operation; Otherwise, after second shifting block 26 (or first shifting block 25) of bull stick 23 is touching second microswitch 261 (or first microswitch 251), then can drive default instruction makes CD-ROM drive motor 24 be reverse rotation, and shutter plate 2 can according to driving member drive reverse directions that two axostylus axostyles 23 are moved gradually closing be closed condition, stop machined object being shone with this.
