The body 1 is provided with an opening facing downward, and baffles 8 are rotatably connected along the length direction of the winding drum 5 on both sides of the opening. The baffles 8 are controlled by a driving motor. One end of a cable 14 is connected to the center of the winding drum 5, and the other end of the cable 14 is connected to the center position of the back of the curtain 4. A wire winding groove 6 is provided in the center of the winding drum 5, and a wire hanging port 7 is fixedly connected to the winding groove 6. One end of the cable 14 is fixedly connected to the wire hanging port 7. The wire winding groove 6 is used to wind up the cable 14. After the cable 14 is accommodated in the wire winding groove 6, the curtain 4 is rolled up by the winding drum 5 to prevent the curtain 4 from bulging in the middle on the winding drum 5 after rolling up, and effectively avoid being stuck between the baffles 8 due to the increased thickness of the winding drum 5.

[0034] See also Figure 1 and Figure 5 The baffles 8 are all tilted upward and do not contact each other during the downward rotation process. The baffles 8 do not contact the winding drum 5. The upward tilted baffles 8 can play a certain guiding role on the rolled-up curtain 4, and can also effectively prevent the curtain 4 from sagging after rolling.

[0035] Example 2

[0036] A suction screen machine, such as Figure 1-5As shown, based on the embodiment 1, the difference from the embodiment 1 is that the top end of the curtain 4 is clamped between the lifting plate 2 and the clamping plate 3, and the top end of the lifting plate 2 is provided with a plurality of lifting plate rings 13 at intervals along the length direction, and a plurality of body rings 9 are provided on the body 1, and the body rings 9 and the lifting plate rings 13 are connected to the lifting and winding machine through a sling. The stage lifting and winding machine can control the height of the body 1 and the lifting plate 2 by controlling the length of the sling, and uses the clamping plate 3 and the lifting plate 2 to clamp the top edge of the curtain 4. When the curtain 4 needs to be wound up, At this time, the curtain 4 can be quickly released. A plurality of electromagnets 11 are arranged at intervals along the length direction on the edge of the lifting plate 2. Magnetic sheets 12 are arranged at positions of the clamping plate 3 corresponding to the electromagnets 11 along the length direction. The plurality of electromagnets 11 are used to attract the magnetic sheets 12, so that the clamping plate 3 and the lifting plate 2 can stably clamp the curtain 4. A convex strip 10 is arranged along the length direction on the side of the clamping plate 3 facing the lifting plate 2. The convex strip 10 can effectively increase the friction between the curtain 4 and the clamping plate 3, so that the clamping plate 3 and the lifting plate 2 can clamp the curtain 4 more stably.

[0037] Example 3

[0038] A suction screen machine, such as Figure 1-5 As shown, based on the embodiment 2, the difference from the embodiment 2 is that the cable 14 connected to the center position of the back of the curtain 4 extends upward in line with the curtain 4, and is clamped between the lifting plate 2 and the clamping plate 3 together with the curtain 4. The height of the lifting plate 2 after rising is maintained at the same height as the body 1. After the cable 14 is clamped between the lifting plate 2 and the clamping plate 3 together with the curtain 4, it can effectively prevent the actor from getting caught on the cable 14 when moving with the props behind the curtain 4.

[0039] The working principle of the present utility model is as follows: after the electromagnet 11 is powered off, the splint 3 rotates downward under its own gravity to release the curtain 4. At the same time as the curtain 4 falls, the reel-up drum 5 starts the reeling cable 14. The cable 14 is first reeled into the reeling groove 6, and the curtain 4 is quickly reeled onto the reel-up drum 5 under the guidance of the baffle 8. After the reel-up drum 5 stops rotating, if the tail end of the curtain 4 is located on both sides of the reel-up drum 5, the tail end of the curtain 4 may sag, and the drooping tail end of the curtain 4 is blocked by the baffle 8 and cannot extend downward from the body 1. When it is necessary to release the curtain in the body 1, the baffle 8 is controlled to rotate and unfold, and then the reel-up drum 5 is rotated in the opposite direction. After the curtain 4 falls to the ground, it is manually clamped by the staff between the lowered lifting plate 2 and the splint 3.
