[0051] The use mode of the utility model is:

[0052] When the door body needs to be opened, the controllers 12 at the front and back of the quick door frame 1 send instructions, and the servo motor 4 starts after receiving the signal, drives the reel 2 to rotate, thereby driving the door curtain to be quickly rolled up from the bottom sealing groove 11 and stored on the reel 2 at the top of the door frame. In this process, the reel cover plate 3 always blocks the door curtain and the reel 2, preventing dust and insects from entering. At the same time, the cylinder 91 in the sealing assembly is controlled by the PLC to retract the attached narrow plate 92 and drive the silica gel strip 93 to retract backward, providing enough space for the door curtain to be rolled up. When the door curtain is completely rolled up, a gap is formed between the silica gel strip 93 and the door curtain, but due to the elasticity of the silica gel strip 93, it can still maintain a certain sealing effect to prevent the invasion of small particles.

[0053] When the door body needs to be closed, the controllers 12 send instructions again, and the servo motor 4 rotates in the opposite direction to drive the reel 2 to release the door curtain. The door curtain falls vertically under the guidance of the second groove 10 and accurately enters the bottom sealing groove 11. At this time, the cylinder 91 again pushes the attached narrow plate 92 under the synchronous control of the PLC, so that the silica gel strip 93 tightly fits between the door curtain and the door frame, forming an effective seal. Since the minimum thickness of the silica gel strip 93 is specified, it can be fully deformed and tightly fit with the door curtain and the door frame, thereby ensuring the sealing performance of the door body. In addition, the buffer sealing rubber at the bottom of the quick door frame 1 can further enhance the sealing effect and prevent the entry of dust and insects. At the same time, the infrared anti-pinch device 6 close to the bottom can monitor the objects below the door body in real time, and immediately stop the closing action of the door body once it detects the presence of an object, preventing the pinching of people or objects.
