[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 The quick disassembly mechanism 5 includes a square seat 51, which is slidably connected to the inside of the connecting shaft 3. The end of the square seat 51 away from the I-wheel 4 is fixedly connected to a guide rod 52, and the end of the guide rod 52 away from the I-wheel 4 is fixedly connected to a pull ring 53. A spring 54 is provided on the outside of the guide rod 52. The guide rod 52 passes through the connecting shaft 3 and is slidably connected to the connecting shaft 3. The pull ring 53 can drive the square seat 51 to move through the guide rod 52. The square block of the square seat 51 is slidably connected to the square hole of the I-wheel 4. The pull ring 53 contacts the connecting shaft 3. The square seat 51 can limit the I-wheel 4. One end of the spring 54 is fixedly connected to the square seat 51, and the other end of the spring 54 is fixedly connected to the connecting shaft 3. The spring 54 can support the square seat 51 through elastic force.

[0022] See also Figure 1 、 Figure 4The second spring 73 is fixedly connected to the reset bar 71, and the other end of the second spring 73 is fixedly connected to the inner top of the fixed cover 6. The second spring 73 can support the reset bar 71 through elastic force.

[0023] Working principle: When in use, after the welding ribbon passes under the lower pressure roller 75, the welding ribbon is wound around the outside of the I-shaped wheel 4, and then the servo drive motor 8 is started. The drive motor 8 drives the I-shaped wheel 4 to rotate through the rubber wheel 9. During the rotation of the I-shaped wheel 4, the welding ribbon is wound. During the winding process, the thickness of the welding ribbon increases, and the welding ribbon applies an upward thrust to the lower pressure roller 75. After the lower pressure roller 75 is subjected to the force, the reset bar 71 compresses the spring 2 73. After the spring 2 73 is compressed, an elastic force is generated. The elastic force can press the welding ribbon downward through the lower pressure roller 75 to tighten it, so that the I-shaped wheel 4 can wrap the welding ribbon more tightly.

[0024] When the winding is completed and the spool 4 needs to be disassembled, the hoisting assembly is installed on the spool 4, and the pull ring 53 is pulled. The pull ring 53 drives the square seat 51 to move through the guide rod 52 and compresses the spring 1 54. When the square seat 51 is separated from the spool 4, the limit on the spool 4 can be released, making it easier to disassemble and replace the spool 4.
