Description

Technical Field

[0001] The utility model relates to the technical field of film winding, and more specifically to a device for adjusting the inner diameter of a winding tube core. Background Art

[0002] Film winding is the material receiving part of the roll material processing production line. The film is rolled into a roll mechanically to facilitate subsequent use. It is mainly driven by the drive of the winder to drive the winding shaft to rotate. At the same time, the winding tube core is sleeved on the outside of the winding shaft. It rotates synchronously with the winding shaft to carry out the film winding work. After that, the winding shaft is removed and the outer winding tube core is removed.

[0003] Based on the above, the inventors discovered that when the existing winding machine is used to wind films of different specifications, it is necessary to install a diameter-increasing sleeve of corresponding size between the winding tube core and the winding shaft to ensure that the winding tube core and the winding shaft rotate synchronously. However, the installation and removal of the diameter-increasing sleeve are relatively cumbersome, which affects the winding efficiency. At the same time, it is necessary to prepare multiple diameter-increasing sleeves to adapt to winding tube cores of different sizes, which is inconvenient to use. Therefore, in view of this, the existing structure is studied and improved, and a device for adjusting the inner diameter of the winding tube core is provided, in order to achieve a more practical purpose.
