Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses bill perforating device of printing machine. Referring to fig. 1, the bill perforating device of the printing machine comprises a mounting frame 1 for placing a paper tape 11, an upper roller 5 rotatably arranged on the mounting frame 1, and a lower roller 9 rotatably arranged on the mounting frame 1. The mounting bracket 1 is fixedly provided with two mounting seats 4, the two mounting seats 4 are correspondingly arranged, the upper roller 5 is rotatably arranged between the two mounting seats 4, the motor 2 is fixedly arranged on the mounting seats 4, and the rotating shaft of the motor 2 is coaxially and fixedly connected with the upper roller 5.

Referring to fig. 2 and 3, specifically, the upper roller 5 is located above the lower roller 9, the upper roller 5 is provided with a mounting ring 7, the mounting ring 7 and the upper roller 5 are integrally formed, the number of the mounting rings 7 is multiple, and the surface of the mounting ring 7 is provided with a plurality of mounting grooves 15. A fixing groove 16 is horizontally formed in the mounting ring 7, the fixing groove 16 is communicated with the mounting groove 15, a screw 13 is arranged on the mounting ring 7, and the screw 13 is horizontally connected to the fixing groove 16 in a threaded mode.
