[0018] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme of the utility model will be described clearly and completely below in conjunction with the drawings.

[0019] The embodiment proposes a kind of cleaning and brushing machine winding sleeve structure, including winding shaft 1 and sleeve 5, winding shaft 1 is connected with external driving motor, sleeve 5 is used to around band material:

[0020] As Figs. 1-3 Shown, the outside circumference of the winding shaft 1 is evenly distributed with expansion plate 2, the one end of the expansion plate 2 is respectively provided with corresponding baffle 3, the other end of expansion plate 2 is provided with lateral protruding positioning block 4;

[0021] The middle part of the sleeve 5 is provided with assembly hole 6 that can be cooperated with expansion plate 2, sleeve 5 is cooperated with expansion plate 2 and is installed on the outside of winding shaft 1 using assembly hole 6, baffle 3 is used to fix one end of sleeve 5, prevent the band material on sleeve 5 from knocking into cleaning and brushing machine body;When expansion plate 2 is tensioned, sleeve 5 is preliminarily fixed on the outside of winding 1, cannot rotate;

[0022] The inner wall of the assembly hole 6 is evenly distributed with positioning plate 7 that can be cooperated with expansion plate 2, the one end of the positioning plate 7 is provided with positioning slot 8 that can be cooperated with positioning block 4;

[0023] When the cleaning machine works, the strip is straightened by large tension to prevent bending and affect the cleaning effect; the consequence of large tension is that the friction between the winding shaft 1 and the sleeve 5 is not enough, causing slipping; when the positioning plate 7 cooperates with the expansion plate 2, the radial position of the sleeve 5 on the winding shaft 1 is limited and cannot rotate, thereby avoiding the generation of the slipping phenomenon; at the same time, when the positioning block 4 enters the inside of the positioning groove 8, the axial position of the sleeve 5 on the winding shaft 1 is limited to prevent the sleeve 5 from axially moving.

[0024] Further, the positioning block 4 is a whole hemisphere protruding from the expansion plate 2, and the positioning groove 8 is an oblong slot; the hemisphere-shaped positioning block 4 is more easily entered into the inside of the oblong positioning groove 8, facilitating cooperation.

[0025] Further, the lower surface of the expansion plate 2 is symmetrically provided with a hinge plate 9, the outer side of the winding shaft 1 is uniformly provided with a mounting seat 10 corresponding to the hinge plate 9, and the hinge plate 9 and the mounting seat 10 are hingedly connected with a connecting plate 11.

[0026] Further, the length of the expansion plate 2 is 1.1-1.3 times the length of the sleeve 5, and the length of the expansion plate 2 is greater than the length of the sleeve 5, so that the supporting effect is better.

[0027] Further, the height of the baffle 3 is 1-1.2 times the wall thickness of the sleeve 5.

[0028] Working principle: in use, the sleeve 5 with the strip is sleeved on the outside of the expansion plate 2, the baffle 3 can limit one end of the sleeve 5 to prevent the strip on the sleeve 5 from colliding with the cleaning machine body; when the expansion plate 2 is tensioned, the sleeve 5 is preliminarily fixed on the outside of the winding shaft 1; the cleaning machine works, the strip is straightened by large tension, at this time, the friction between the expansion plate 2 and the sleeve 5 is not enough, causing slipping, one side of the expansion plate 2 moves against one side of the positioning plate 2, the radial position of the sleeve 5 on the winding shaft 1 is limited and cannot rotate, thereby avoiding continuous slipping and ensuring the cleaning effect; at the same time, when the positioning block 4 enters the inside of the positioning groove 8, the axial position of the sleeve 5 on the winding shaft 1 is limited to prevent the sleeve 5 from axially moving.

[0029] It can be understood that the above embodiments are only exemplary embodiments for illustrating the principle of the utility model, and the utility model is not limited thereto. For ordinary skilled persons in the art, various modifications and improvements can be made without departing from the spirit and essence of the utility model, and these modifications and improvements are also regarded as the protection scope of the utility model.
