DETAILED DESCRIPTION

[0036] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0037] Referring to Figures 1-14 The present application provides a paper tube deviation correcting device for a production line, which comprises a housing 1, a winding roller 1.1 rotatably connected to the housing 1, and a roller 1.5 slidably connected to the housing 1, and further comprises an elastic shaft assembly 1.21 rotatably connected to the housing 1 and coaxially arranged with the winding roller 1.1.

[0038] A transmission assembly is arranged on the housing 1, one end of the transmission assembly being driven by the winding roller 1.1 and the other end of the transmission assembly being connected to the roller 1.5.

[0039] When the tension of the paper tape reaches a preset value, the winding roller 1.1 drives the transmission assembly in the deviation process, so as to drive the roller 1.5 to move upward, thereby reducing the tension of the paper tape and keeping the tension of the paper tape within a certain range, so as to avoid tearing of the paper tape.

[0040] Specifically, as Figure 1 , 7As shown in Figure 8, a winding roller 1.1 is rotatably connected inside the housing 1. The winding roller 1.1 is driven by a motor 1.7, and the winding roller 1.1 is coaxially and fixedly connected to the output shaft of the motor 1.7. The motor 1.7 is fixedly mounted on the housing 1. A roller 1.5 is slidably connected inside the housing 1. The roller 1.5 moves in the vertical direction of the housing 1. By moving the roller 1.5 in the vertical direction of the housing 1, the tension of the paper tape can be adjusted so that the tension of the paper tape is always kept within a certain range. In this invention, a traction mechanism (not shown in the figure) is provided in the axial direction of the winding roller 1.1. The wound paper tube is pulled by the traction mechanism.
