The middle part of the cloth winding roller 21 is a cloth winding section 212, and the two ends of the cloth winding roller 21 are mounting end portions. A cloth clamping layer is formed between the cloth winding section 212 and the cloth guiding block 11, and a cloth clamping structure is arranged between the cloth winding section 212 and the cloth guiding block 11 to prevent the cloth head from slipping. Further, the cloth winding section 212 is provided with an elastically arranged pawl 213, the cloth guiding block 11 is provided with a limiting portion matched with the pawl 213 to prevent the cloth head from slipping during winding, the pawl 213 and the limiting portion are correspondingly arranged, and the pawl 213 and the limiting portion constitute the cloth clamping structure. Further, the limiting portion is a limiting groove or a limiting hole, the pawl 213 is matched with the limiting groove by extrusion, or the limiting portion is a limiting hole, and the pawl 213 is limited in the limiting hole. Further, the cloth winding section 212 is a cloth winding structure formed with an angle, which can further prevent slipping during winding, especially prevent slipping when the empty roller fixes the cloth head. The cloth guiding block 11 is a strip block matched with the shape and size of the cloth winding section 212. In the embodiment, as shown in the drawings, the cloth guiding block 11 is a strip block with a rectangular cross section, and the cloth winding section 212 is a cloth winding structure formed with an angle. Figure 4 and Figure 5The limiting part is a limiting hole 111. The pawl 213 is limited in the limiting hole 111. The cloth winding section 212 is a square roller, and the number of the pawls 213 is several, specifically three. The cloth guide block 11 is an L-shaped strip block, and the number of the limiting holes 111 is several, specifically three. The limiting hole 111 extends to the two supporting walls of the L-shaped strip block. The pawl 213 is self-adapting and telescopic through the spring. When the cloth head is fixed, the pawl 213 can bite the cloth head and be limited in the limiting hole 111. When the cloth winding roller 21 rotates, the pawl 213 can be self-adapting from the position of the limiting hole 111 to the position of abutting against the supporting wall of the cloth guide block 11. At this time, the pawl 213 bites the cloth head and rotates together, which can avoid the phenomenon of cloth head running and sliding as much as possible, and finally the cloth head is fixed on the cloth winding roller 21.

[0047] The cloth winding roller 21 is installed in a combined or separated manner relative to the cloth guide block 11, or the cloth guide block 11 is installed in a combined or separated manner relative to the cloth winding roller 21.
