[0034] Please see Figure 1-2An imaging cutting device provided in this application includes: a base 1 and a cutting unit 2; the cutting unit 2 includes a cutting slice 5 and two sets of driving components 6; the cutting slice 5 is slidably disposed on one side of the base 1; the cutting slice 5 is provided with a guide portion 52 and two first sliding grooves 51, the two first sliding grooves 51 are symmetrically disposed on both sides of the guide portion 52, and the two first sliding grooves 51 extend in the same direction, the guide portion 52 passes through the extension line of the first sliding grooves 51; the base 1 is provided with a light-transmitting hole 42 and a second sliding groove 41, the guide portion 52 is rotatably engaged in the second sliding groove 41, and the guide portion 52 can slide along the second sliding groove 41; the driving components 6 include a driving mechanism 61 and a transmission mechanism. The drive mechanism 61 is mounted on the base 1. The transmission mechanism 62 includes a pull rod 621, a first connecting rod 622, and a second connecting rod 623. The power output end of the drive mechanism 61 is connected to one end of the pull rod 621 to drive the pull rod 621 to move back and forth in a straight line relative to the base 1. The other end of the pull rod 621 is rotatably connected to one end of the first connecting rod 622. The other end of the first connecting rod 622 is rotatably connected to one end of the second connecting rod 623 on the base 1. The other end of the second connecting rod 623 is provided with a sliding part 626. Each sliding part 626 is rotatably engaged in each of the first sliding grooves 51, and the sliding part 626 can slide along the first sliding groove 51.
[0035] In this embodiment, the drive mechanism 61 drives the pull rod 621 to move back and forth in a straight line relative to the base 1. The pull rod 621 drives the first connecting rod 622 to rotate, and the first connecting rod 622 drives the second connecting rod 623 to rotate, so that the sliding part 626 slides along the first sliding groove 51, causing the light cutter 5 to rotate. At the same time, it drives the guide part 52 to slide along the second sliding groove 41, realizing multi-angle movement of the light cutter 5 and more accurate positioning.

[0036] Further, the driving mechanism 61 includes a screw 611 rotatably connected to the base 1, and a slider 624 slidably connected to the base 1 at one end of the pull rod 621.

The knob 612 corresponds one-to-one with the drive assembly 6. In use, the operator operates the knob 612 to rotate the screw 611, and the slider 624 slides along the third slide groove 31 as the screw 611 rotates, thereby driving the pull rod 621 to reciprocate linearly relative to the base 1. In other embodiments, a pneumatic / hydraulic cylinder can also be used as the drive mechanism 61 to drive the pull rod 621 to slide.
[0038] Furthermore, a limiting component is provided between the second link 623 and the base 1 to limit the rotation angle of the second link 623.
[0039] Specifically, the limiting component includes a limiting post 628 disposed on the base 1 and a limiting groove 627 disposed on the second connecting rod 623, wherein the limiting post 628 is slidably engaged within the limiting groove 627. By providing the limiting groove 627 and the limiting post 628, the rotation range of the second connecting rod 623 is limited when the second connecting rod 623 drives the slicing slice 5 to slide.
[0040] Furthermore, multiple sets of the aforementioned light-cutting units 2 are provided, and multiple light-cutting blades 5 are arranged circumferentially along the outer periphery of the light-transmitting hole 42. The multiple sets of light-cutting blades 5 cooperate with each other to form different patterns at the light-transmitting hole 42, which also improves the cutting accuracy.
[0041] Furthermore, the base 1 includes a frame 3 and a cross cover 4; the frame 3 has an opening defined inside, the cross cover 4 is connected to the frame 3 and covers the opening, the light-transmitting hole 42 and the second sliding groove 41 are both provided on the cross cover 4; the driving mechanism 61 is installed on the frame 3, and the other end of the first connecting rod 622 and one end of the second connecting rod 623 are rotatably connected to the frame 3; making the device layout more reasonable and easier to disassemble and maintain.
[0042] Furthermore, four sets of the light-cutting units 2 are provided, and the base 1 includes two cross covers 4; the two cross covers 4 are respectively disposed on the upper and lower surfaces of the frame 3, and each light-cutting piece 5 is disposed between the two cross covers 4; each cross cover 4 is provided with two second sliding grooves 41, and on any cross cover 4, the two second sliding grooves 41 are symmetrically disposed on both sides of the light-transmitting hole 42, and the two second sliding grooves 41 extend in the same direction, and the light-transmitting hole 42 passes through the extension line of the second sliding grooves 41; the second sliding grooves 41 on the two cross covers 4 are perpendicular; a plurality of guide parts 52 are correspondingly engaged in each of the second sliding grooves 41.
[0043] Specifically, the four light cutters are arranged in pairs, with two pairs of light cutters stacked one on top of the other; for example, refer to the attached document. Figure 1 As shown, the two light cutters located at the top are symmetrically arranged on the left and right sides of the light-transmitting hole, and the two light cutters located at the bottom are symmetrically arranged on the top and bottom sides of the light-transmitting hole.
[0044] In this embodiment, the frame 3 is also provided with multiple fixing posts, and two cross caps 4 are fixedly installed on the fixing posts.
[0045] Furthermore, each group of drive mechanisms 61 is arranged along the same side of the frame 3, which makes the layout simple and convenient to operate.
[0046] This application also provides a stage cutting light, which includes the imaging cutting device described above. The stage cutting light has a simple structure and is easy to disassemble and maintain.
[0047] In summary, the imaging cutting device provided in this embodiment, during use, drives the pull rod 621 to move back and forth in a straight line relative to the base 1 via the drive mechanism 61. The pull rod 621 drives the first connecting rod 622 to rotate, and the first connecting rod 622 drives the second connecting rod 623 to rotate. This causes the sliding part 626 at the end of the second connecting rod 623 to slide along the first sliding groove 51 on the light cutter 5, thereby rotating the light cutter 5. Simultaneously, it drives the guide part 52 on the light cutter 5 to slide along the second sliding groove 41 on the base 1, causing the light cutter 5 to slide towards the light-transmitting hole 42, thus cutting the light beam passing through the light-transmitting hole 42. This device can achieve multi-angle movement of the light cutter 5, with accurate positioning and higher adjustment precision.
