The rear end outside of the clamping column 14 is slidably connected to the rear part of the rotating disk 5 and the side end of the bracket 1 respectively. By sliding out the clamping column 14, the rotating disk 5 can be rotated half a circle so that the positions of the two sets of rotating shafts 12 can be interchanged. In this way, the curtain fabric can be unloaded while being rolled up, which increases the work efficiency. One end of the spring 15 is fixedly connected to the middle side of the clamping column 14, and the other end of the spring 15 is fixedly connected to the rear end outside of the rotating disk 5. The spring 15 is pulled to keep the clamping column 14 relatively fixed, so that the rotating disk 5 can be kept fixed. A clamping block 16 is slidably connected to the inner wall of the rear part of the clamping column 14. The clamping block 16 can limit the clamping column 14 to rotate horizontally only within a fixed distance and will not slide out of the interior of the rotating disk 5. The outside of the clamping block 16 is fixedly connected to the rear end inside of the rotating disk 5.

[0032] Reference Figure 1-Figure 2 A power assembly is fixedly arranged at the front of the rotating disk 5, and the power assembly can drive the rotating shafts 12 at both ends to rotate so that the fabric can be rolled up. The power assembly includes a motor 7, which can provide power. A main gear 6 is fixedly connected to the rear output shaft of the motor 7, and the main gear 6 can rotate under the drive of the motor 7. Sub-gears 13 are meshed at both ends of the main gear 6. The sub-gear 13 rotates with the main gear 6 to transmit power to the rotating gear 8. The side end of the sub-gear 13 is meshed with a rotating gear 8, and the rotating gear 8 can drive the rotating shaft 12 to rotate. The lower part of the motor 7 is fixedly connected to the front end side of the rotating disk 5, and the motor 7 is supported by the rotating disk 5 to remain relatively fixed. The rear parts of the main gear 6 and the sub-gear 13 are both rotatably connected to the front part of the rotating disk 5. The rotating disk 5 limits the main gear 6 and the sub-gear 13 to only rotate relative to each other. The middle of the rotating gear 8 is fixedly connected to the rear part of the rotating shaft 12. The rotation of the rotating gear 8 can drive the rotating shaft 12 to rotate, so that the winding sleeve 4 can rotate accordingly to roll up the curtain fabric.

[0033] Reference Figure 1-Figure 2The two ends of the front of the rotating disk 5 are rotatably connected with a rotating shaft 12, and the rotating shaft 12 can support the winding sleeve 4 to keep it in a horizontal state. The outside of the rotating shaft 12 is slidably connected with the winding sleeve 4, and the winding sleeve 4 can roll up the curtain fabric for convenient transportation. The front end of the rotating shaft 12 is slidably connected with a trapezoidal block 9. The front end surface of the trapezoidal block 9 is an inclined surface and can be squeezed to slide into the interior of the rotating shaft 12, which is convenient for the winding sleeve 4 to slide in. The trapezoidal block 9 is provided with two groups, and the two groups of trapezoidal blocks 9 are elastically connected by a spring 11. The spring 11 can squeeze the trapezoidal block 9 to slide out so that the winding sleeve 4 can be rolled up. The sleeve 4 is clamped and fixed by the rotating gear 8 and the trapezoidal block 9. The outside of the trapezoidal block 9 is slidably connected to the inside of the front end of the winding sleeve 4. The two ends of the spring 11 are respectively fixedly connected to the outside of the side ends of the two groups of trapezoidal blocks 9. The trapezoidal block 9 can drive the winding sleeve 4 to rotate with the rotating shaft 12 to roll up the curtain fabric. The side end of the trapezoidal block 9 is fixedly connected with a positioning block 10. The positioning block 10 can prevent the trapezoidal block 9 from completely sliding out of the front end of the rotating shaft 12. The outside of the positioning block 10 is slidably connected to the inside of the front end of the rotating shaft 12. The front part of the winding sleeve 4 is fixedly connected with a material receiving assembly.

[0034] Reference Figure 1 and Figure 4 The material receiving assembly includes a positioning rod 18, which can limit the U-shaped block 17 to slide linearly within a fixed distance relative to the winding sleeve 4. The upper and lower parts of the positioning rod 18 are fixedly connected to the front end of the winding sleeve 4. The winding sleeve 4 keeps the positioning rod 18 relatively fixed. The outer sliding connection of the positioning rod 18 is provided with a U-shaped block 17. The lower end of the U-shaped block 17 is an inclined surface that can squeeze the trapezoidal block 9 to slide back into the rotating shaft 12, and the middle inner wall can prevent the trapezoidal block 9 from sliding out, so that the winding sleeve 4 with the curtain fabric rolled up can be conveniently slid out for unloading. The lower part of the U-shaped block 17 is in contact with the upper part of the trapezoidal block 9. The upper and lower end sides of the positioning rod 18 are fixedly connected with magnets 19. The magnet 19 adsorption can keep the U-shaped block 17 in a fixed position, so that the sliding out of the winding sleeve 4 is more convenient, and the winding sleeve 4 can be kept stable relative to the rotating shaft 12 during winding. The side end of the magnet 19 is in contact with the outer side of the U-shaped block 17.

[0035] Working principle: The curtain fabric can be squeezed by the squeezing device 2 so that it can remain in a relaxed state when passing through the squeezing roller 3 and the squeezing device 2, and then the main gear 6 is driven by the motor 7 to rotate, the main gear 6 drives the sub-gear 13 to rotate, the sub-gear 13 drives the rotating gear 8 to rotate, the rotating gear 8 rotates to drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the trapezoidal block 9 to rotate, so that the winding sleeve 4 can rotate with the trapezoidal block 9, so that the curtain fabric can be rolled up on the middle outer wall of the winding sleeve 4. After the winding is completed, the clamping column 14 can be slid outward, and the clamping column 14 slides out of the side end of the bracket 1 to pull the spring 15 until the clamping block 16 restricts the clamping column 14 from sliding, and then the clamping column 14 is rotated, and the clamping column 14 drives the rotating disk 5 to rotate halfway. The rotating disk 5 drives the rotating shaft 12 and the winding sleeve 4 at both ends to rotate half a circle, so that the other set of winding sleeves 4 rotates to the left end winding position, and then releases so that the clamping column 14 slides into the side end of the bracket 1 under the pulling force of the spring 15 and remains relatively fixed, and then slides the U-shaped block 17 at the right end so that the inclined surface of its lower end squeezes the trapezoidal block 9 to slide into the rotating shaft 12 and squeeze the spring 2 11. At this time, the U-shaped block 17 is adsorbed and kept fixed by the magnet 19, and then slides out the winding sleeve 4 that has rolled up the curtain fabric, and then slides the new winding sleeve 4 onto the rotating shaft 12. At this time, the inclined surface of the trapezoidal block 9 is squeezed and slides into the rotating shaft 12. When the winding sleeve 4 slides to a certain position, the spring 2 11 squeezes the trapezoidal block 9 to slide into the front end of the winding sleeve 4 to fix it.
