Making the hot spot of light beam, to form square, rhombus, triangle etc. variously-shaped or project the good pattern of various predetermined designs.
Wherein cutter sweep includes multiple cutting sheets, and predetermined image is formed come shield portions light beam using the movement of cutting sheet
, in the prior art in cutter sweep, there is train wheel bridge with lower plate to make cutting sheet be moved along specified direction, cutting in case
Piece drives what connecting rod was moved by motor, and cutting sheet has horizontal direction and longitudinal direction is cut, so as to be formed
Different patterns, and the chute above existing train wheel bridge determines its quantity typically according to the quantity of connecting rod, and grating is connected
There are multiple fixing points on bar, and in chute, due to there is multiple motor points and multiple simultaneously in motion, and on train wheel bridge
Limit point, grating connecting rod is when mobile, it is easy to make train wheel bridge stuck, while multiple cutting sheets are located at and are transported with a region
It is dynamic, it is easy to stuck phenomenon occur so that cutter sweep stop motion and break down, and cutting sheet is when intersecting, by
In can not possibly dock completely very well, therefore light source cannot completely be blocked by cutting sheet, so that there is the phenomenon of light leak.
Utility model content
The utility model discloses a kind of light of stage cutter sweep, it is used to solve the deficiencies in the prior art.
To solve the above problems, technical solution of the present utility model is：
A kind of light of stage cutter sweep, including mainboard, are provided with the circular aperture passed through for light beam on mainboard, described
Mainboard on eight fixed rotating shafts are distributed with circumference relative to the center of aperture, fixed rotating shaft is mounted on bearings,
Cutting sheet plectrum is installed, two cutting sheet plectrums are connected with a cutting sheet on fixed rotating shaft, the quantity of cutting sheet is four,
Cutting sheet is " one " font groove with the link position of cutting sheet plectrum, and train wheel bridge, lower section peace are provided with above cutting sheet
Equipped with lower plate, train wheel bridge is linked together with lower plate by clamping plate support base, and train wheel bridge is also equipped with sliding with lower plate
Pad, has two to intersect the cutting sheet for setting between train wheel bridge and sliding shim, also there is two between lower plate and sliding shim
The intersecting cutting sheet for setting, is provided with a guide pillar in cutting sheet, two are respectively arranged with train wheel bridge and lower plate and are located at one
" yi word pattern " guide groove on bar straight line, cutting sheet is slided in the presence of guide pillar in " yi word pattern " guide groove of train wheel bridge.
Eight described fixed rotating shafts are driven by eight independent motors respectively.
The center of described sliding shim, train wheel bridge and lower plate is provided with a circular port passed through for light beam,
And the diameter of this circular port is less than the diameter of the center hole of aperture.
The beneficial effects of the utility model are：Two cutting sheets only by a gathering sill on train wheel bridge realize being oriented to
Motion, while cutting sheet is located at two different spaces, non-interference, two cutting sheets in same space
Be not in interference, occur stuck, light leak phenomenon during exercise so as to avoid cutting sheet, move device and more may be used
Lean on.
Brief description of the drawings
Fig. 1 is exploded perspective view of the present utility model；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is structural representation of the present utility model；
In figure：2- fixed rotating shafts, 4- bearings, 6- mainboards, 8- sliding shims, 10- clamping plate support bases, 11- train wheel bridges, 13-
Cutting sheet plectrum, 14- cutting sheets, 15- lower plates, 17- apertures.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to accompanying drawing 1-2, the utility model includes mainboard 6, the circular aperture passed through for light beam is provided with mainboard 6
17, eight fixed rotating shafts 2 are distributed with the circumference on described mainboard 6 relative to the center of aperture 17, fixed rotating shaft 2 is pacified
On bearing 4, cutting sheet plectrum 13 is installed on fixed rotating shaft 2, two cutting sheet plectrums 13 are connected with a cutting sheet 14,
The quantity of cutting sheet 14 is four, and cutting sheet 14 is " one " font groove, cutting sheet with the link position of cutting sheet plectrum 13
14 top is provided with train wheel bridge 11, and lower section is provided with lower plate 15, and train wheel bridge 11 passes through clamping plate support base 10 with lower plate 15
Link together, train wheel bridge 11 is also equipped with sliding shim 8 with lower plate 15, there are two between train wheel bridge 11 and sliding shim 8
The intersecting cutting sheet 14 for setting, also has two to intersect the cutting sheet 14 for setting, cutting sheet 14 between lower plate 15 and sliding shim 8
On be provided with a guide pillar, be respectively arranged with train wheel bridge 11 and lower plate 15 two be located at straight line on " yi word patterns " lead
Groove, cutting sheet 14 is slided in the presence of guide pillar in " yi word pattern " guide groove of train wheel bridge 11.
Eight described fixed rotating shafts 2 are driven by eight independent motors respectively.
The center of described sliding shim 8, train wheel bridge 11 and lower plate 15 is provided with a circle passed through for light beam
Shape hole, and this circular port diameter less than aperture 17 center hole diameter.
In actual applications, a cutting sheet 14 is connected by two cutting sheet plectrums 13, the direction of motion of cutting sheet 14
Determined by the aggregate motion of two cutting sheet plectrums 13, and guide groove only one of which " yi word pattern " guide groove on train wheel bridge 11, relatively
The direction of motion is unique, therefore it is during aggregate motion, will not make cutting sheet because of different movement combination modes
