Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

Referring to fig. 1-4, a winding core according to a preferred embodiment of the present invention includes an inner core 1 and an outer sleeve 2;

the inner core 1 is a multi-layer composite paper tube, and the inner wall of the outer sleeve 2 is adhered to the inner core 1 through a glue layer;

the two ends of the inner core 1 exceed the end surface of the outer sleeve 2.

The outer sleeve 2 wraps the outer side of the conventional inner core 1, the outer sleeve 2 is an elastic component, and when the elastic outer sleeve 2 winds a film material, the innermost film cannot be abraded due to the fact that the outer surface of a paper tube is uneven;

the outer sleeve 2 is attached to the inner core 1 in a glue adhering mode, the mode is simple, and compared with a conventional structure in which double-sided glue is attached, the operation is more convenient;

the length of the inner core 1 exceeds the end face of the outer sleeve 2, so that the outer sleeve 2 is prevented from being cut and damaged by other devices when in use.

Furthermore, glue layers are arranged at two ends of the outer sleeve 2, and the width of each glue layer is 5-10 cm.

In order to save the use amount of glue, the glue is coated at the two ends of the outer sleeve 2.

Further, a bush 3 is inserted into a central round hole of the inner core 1.

The lining 3 is stuffed into the inner core 1 and fixed by glue, so as to protect the inner opening of the pipe section of the inner core 1.

Further, the middle part of the bush 3 is in a through hole shape.

The middle through hole of the bush 3 is convenient for being matched with a corresponding pipe fitting for installation and use.

Further, the outer part of the bush 3 is provided with a cover sheet 4 which covers the outer end surface of the inner core 1.

The outside of bush 3 has the cover piece 4 of outwards spreading, and cover piece 4 just covers on the terminal surface of inner core 1, adopts glue to fix, and cover piece 4 can be for the terminal surface of inner core 1 provides the effect of protection, avoids the condition of wastepaper to appear in the inner core 1 of paper when using.

Further, the outer side of the covering sheet 4 is provided with a downward extending wrapping layer 5 wrapping the outer wall of the inner core 1.

The wrapping layer 5 wraps the outer side of the inner core 1 for protection, and the paper scrap condition of the paper inner core 1 in use can be avoided.

Further, the upper end of the inner core 1 is provided with a step-shaped structure 6 of the wrapping layer 5 for placing the wrapping layer 5.

Further, the height of the stepped structure 6 corresponds to the thickness of the wrapping layer 5.

The height of the step-shaped structure 6 is consistent with the thickness of the wrapping layer 5, the wrapping layer 5 is just clamped in the step-shaped structure 6 after being installed, the outside is smooth, and no convex structure exists.
