Description

TECHNICAL FIELD

[0001] The utility model relates to a paper winding device technical field especially a kind of paper winding device connecting head of integrated hoop structure. BACKGROUND

[0002] In the field of photo printer printing, the paper winding device can automatically and timely collect and release the printing consumables, greatly saving the time and labor cost consumed by manual winding. The paper winding device currently applied to the photo printer is mainly composed of a paper collecting mechanism and a paper releasing mechanism. The paper releasing mechanism is located at the rear of the photo printer, and the paper collecting mechanism is installed at the front of the photo printer. The printing consumables are released from the rear paper releasing mechanism and are wound on the printing medium (winding drum) after passing through the photo printer to complete the printing process. Since there are differences in the width of the printing consumables, the printing consumables are usually wound on the winding medium. The paper collecting mechanism and the paper releasing mechanism both clamp the two ends of the winding medium by using two paper winding devices, and the positions of the two paper winding devices can be flexibly adjusted to adapt to printing consumables of different widths. The paper winding device is divided into a driven paper winding device without a motor and a driven paper winding device with a motor. Both of them are provided with a paper winding wheel for clamping the winding medium. By clamping the paper winding wheel at the end of the winding medium and driving the paper winding wheel to rotate by the motor, the printing consumables are released from the winding medium, or the printed consumables are wound on the winding medium.

[0003] However, the existing paper winding wheel, i.e., the paper winding device connecting head, is mainly connected by a rotating shaft when connected with the paper winding device. The paper winding wheel and the rotating shaft are combined by in-mold forming process or rely on special fixing structure. This connection mode exposes obvious disadvantages in actual use, i.e., the paper winding wheel is not convenient to disassemble. Once the paper winding wheel needs to be replaced due to damage or wear, or different specifications of paper winding wheels need to be replaced due to different operation requirements, the complex disassembly process will consume a lot of time and energy, affect the use efficiency and maintenance convenience of the photo printer, and thus adversely affect the overall work efficiency of the photo printer.
