Abstract

The present application relates to a winding device, a winding pin, and a winding method. A winding device (100) comprises a base (20) and at least two winding pins (10). The base (20) has a winding position (21) and an ending position (22). The winding position (21) and the ending position (22) are each provided with a winding pin (10), and the winding pin (10) at the winding position (21) can exchange position with the winding pin (10) at the ending position (22). Each winding pin (10) comprises a main body part (11) and a first cutter assembly (12); the first cutter assembly (12) comprises first cutters (121) arranged inside the main body part (11); and the main body part (11) is configured to be capable of rotating circumferentially around its own axial direction relative to the first cutters (121), and the circumference of the main body part (11) is configured to be a winding surface (112) used for winding of a material (300) when the main body part rotates. The winding pin (10) located at the winding position (21) winds the head end of the material (300) on the winding surface (112), and exchanges position with the winding pin (10) located at the ending position (22) when the winding is completed. The first cutters (120) in the winding pin (10) at the winding position (21) after the exchange cut off the tail end located on the winding surface (112). In this way, the winding device (100) of the present application can switch the material (300) at the winding position (21), thereby shortening a feeding length and improving the production efficiency.
