Reflector 6, reflector 6 is provided with the loophole that passes through for light beam.Described reflector 6 is installed in by the top of cutting the cutter sweep that mating plate 2 forms, the first guide plate 51(is the guide plate that Fig. 2 shows middle the top) the below, be used for reducing the absorption of light and the generation of heat, be preferably aluminum alloy plates with mirror surface, usually have the very little surface of roughness;
Shown in Fig. 4-7, transmission mechanism comprises fork 31 and connecting pin 34; Wherein an end of fork 31 is fixedly connected with the output shaft of drive motors 41, offers sliding tray 311 on the other end of fork 31.
As shown in Figure 6, the both sides of cutting blade 2 are respectively arranged with the first ear formula structure and the second ear formula structure, are provided with on the first ear formula structure on circular hole 22, the second ear formula structures and are provided with sliding eye 21.
Such as Fig. 5, shown in Figure 8, the circular hole 22 of cutting blade 2 is connected with sliding eye and is connected by connecting pin 34 with the fork 31 of both sides respectively.
Such as Fig. 5, Fig. 9, Figure 10, shown in Figure 11, connecting pin 34 comprises rounded nose, the first cylinder and the second cylinder that connects successively; Be provided with spacing guide pillar 33 on the second cylinder; Rounded nose and spacing guide pillar 33 are limited in fork 31 and cutting blade 2 on the first cylinder, are matched in clearance between the first cylinder of connecting pin 34 and sliding tray 311, circular hole 22 or the sliding eye 21.Drive motors 41 drives fork 31 and moves in a circle within the specific limits, connecting pin 34 is in the sliding tray 311 interior slips of fork 31 other ends, because the effect of the sliding tray 311 of fork 31, do the cam curve motion so that connecting pin 34 drives cutting blade 2, and then drive the multi-faceted motion of cutting blade 2 realizations.
As shown in Figure 3, the spacing guide pillar 33 on the connecting pin 34 is plugged in the corresponding gathering sill 50, is used for cutting blade 2 corresponding to guiding and moves along the direction of gathering sill 50.The inwall two ends of gathering sill 50 define the swing limit of fork 31 and the mobile limit of cutting blade 2.
Such as Fig. 4, shown in Figure 5, fork 31 is fixedly connected with axle sleeve 32 by bolt arrangement, can certainly adopt other structures to fix, such as laser electric welding etc.Axle sleeve 32 is provided with the axis hole that cooperates with the output shaft of drive motors, and axle sleeve 32 is fixedly connected with the output shaft of drive motors 41.
As shown in Figure 2, rotary drive mechanism comprises the tooth bar 13 that is installed on the fixed mount 11, be installed in the gear 14 on the rotating disc 12 and be installed in electric rotating machine 16 on the rotating disc 12, the centre bore of the motor shaft of electric rotating machine 16 and gear 14 is connected, and gear 14 is connected with a joggle with tooth bar 13.
The maximal translation stroke of arbitrary cutting blade 2 is more than or equal to the diameter of loophole, and arbitrary cutting blade 2 is when the first extreme position of maximal translation stroke, and this cutting blade 2 separates fully with loophole 121, as shown in figure 12; When cutting blade 2 is in the position of interfering beam, these cutting blade 2 partial coverage loopholes 121, as shown in figure 13; When cutting blade 2 was in the second extreme position, this cutting blade 2 covered loophole 121 fully.
Guide plate 5, reflector 6, each spacer 7, mistake tabula rasa 8 are bolted on the rotating disc 12, and position by the spacer that interts on bolt between each spacer 7.
Operation principle of the present invention: when 2 pairs of light beams of need cutting blade carry out dissection, each drive motors 41 drives respectively fork 31 rotations, the other end of fork 31 drives connecting pin 34 in sliding tray 311 interior slips, and connecting pin 34 drives cutting blade 2 and 33 motions of spacing guide pillar.As shown in figure 12, cutting blade 2 is in the outside of loophole 121 projections, and cutting blade 2 is not tackled light beam, and spacing guide pillar 33 places gathering sill 50 away from an end of loophole 121.As shown in figure 13, when 2 pairs of light beams of needs cutting blade carry out dissection, drive motors 41 drives a fork 31 that is fixed on this motor shaft end and swings towards loophole 121 directions, because spacing guide pillar 33 is limited at gathering sill 50 interior slips, synthetic as can be known according to the vector of motion, connecting pin 34 will slide in sliding tray 311 interior ends to fork 31, meanwhile, because cutting blade 2 also links together with spacing guide pillar 33, cutting blade 2 is along with spacing guide pillar 33 slides to loophole 121, synthetic as can be known by the vector of motion, connecting pin 34 also will slide to the end of cutting blade 2 simultaneously, rotate by the axis of cutting blade 2 around spacing guide pillar 33 again, can be so that cutting blade 2 partially or even wholly enters into loophole 121, thereby the light beam that the stage lamp light source projects is gone out partially or even wholly cuts, and changes the cross section of light beam, the stage beam effect that obtains envisioning.When a pair of drive motors drives fork 31 simultaneously with the identical direction of identical speed, can obtain cutting blade 2 and shift to abreast loophole 121 or shift out loophole 121, thereby can realize cutting abreast light beam.
The present invention is by arrangement and the mating reaction of each driving mechanism, transmission mechanism, can cut out easily the patterns such as various parallelogram, trapezoidal, triangle.In addition, rotatablely move by rotating mechanism driven rotary dish 12, the patterns such as above-mentioned various parallelogram, trapezoidal, triangle can be rotated, thereby can obtain more easily the light beam moulding enriched.
