Due to the narrow space around the paper guide roller, the traditional manual knocking disassembly method is difficult to find the force angle and direction, and cannot effectively and stably disassemble the paper guide roller bearing. In addition, the disassembly process is time-consuming and laborious. Therefore, it is necessary to propose improvements. Utility Model Content

[0029] In the above embodiment, the paper guide roller is placed in the space between the annular support frame and the support plate, the outer cylinder of the paper guide roller is fitted into the center hole of the annular support frame and fixedly connected, the pull rod is pressed against the fixed shaft of the paper guide roller, and the pull rod is rotated to cause the annular support frame and the support plate to move axially to pull out the outer cylinder. The force angle and direction of the disassembly tool are uniform, and the paper guide roller bearing can be effectively and stably disassembled, and the disassembly process is time-saving and labor-saving.

[0030] In a specific embodiment: the annular support frame 1 includes an inner sleeve 1-1 and an outer annular base 1-2 which are coaxially arranged, and the inner sleeve 1-1 and the outer annular base 1-2 are fixedly connected.

[0031] In a specific embodiment: the said top-tightening fixing member 4 is provided in plurality and is evenly distributed on the circumference of the inner sleeve 1 - 1 , and the axis of the said top-tightening fixing member 4 is arranged along the radial direction of the inner sleeve 1 - 1 .

[0032] Preferably, the tightening fixing member 4 is a fixing screw, and the fixing screw is screwed into the threaded hole on the side wall of the inner sleeve 1-1.

[0033] In the above structure, the outer cylinder of the paper guide roller is connected with the annular support frame by a tightening fixture, so as to ensure that the annular support frame does not fall off and is evenly stressed during disassembly.

[0034] In a specific embodiment: the annular support base frame 1 and the support plate 2 are fixedly connected by threaded connecting rods 3 evenly distributed around the circumference, and both ends of the threaded connecting rods 3 are respectively connected to the annular support base frame 1 and the support plate 2 by fixing nuts 7.

[0035] In the above structure, the threaded connecting rod is connected to the annular supporting base frame and the supporting plate by bolts, and the position can be adjusted according to actual conditions.
