Abstract

The invention discloses a paper pressing wheel fixing device comprising a disc-shaped fixing baseplate. A convex driving tooth array composed of convex driving teeth is arranged on the side wall of the fixing baseplate, a fixing shaft hole is formed in center of the fixing baseplate, and three arc-shaped through positioning clamping grooves are formed in the circumferential direction of the fixing shaft hole. By the aid of the fixing shaft hole in the center of the fixing baseplate and the three arc-shaped through positioning clamping grooves in the circumferential direction of the fixing shaft hole, installation of a paper pressing wheel is facilitated greatly. Due to bilateral drive, stability of the paper pressing wheel in high-speed rotation is improved greatly. The paper pressing wheel fixing device is simple in structure, convenient to use and high in practicality.

Description

Fixing device for paper pressing wheel

Technical Field

The invention relates to a printing device, in particular to a fixing device of a paper pressing wheel.

Background

A platen is a common printing aid and is used for the pressing and guiding of paper. The existing paper pressing wheel is driven by a single-end rack, and the paper pressing wheel is easy to be tilted on one side when rotating at high speed, so that 'paper sliding' occurs. In addition, the existing paper pressing wheel is directly fixed by a screw, and is easy to generate eccentric displacement after long-time rotation, so that the paper pressing precision is influenced.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a fixing device for a paper pressing wheel.

The technical problem of the invention is mainly solved by the following technical scheme:

the utility model provides a press fixing device of paper wheel, press fixing device of paper wheel contain the fixed base disc of a cake form, the lateral wall of fixed base disc on be equipped with the drive odontoid process array of constituteing by the drive odontoid process, the center of fixed base disc be equipped with a fixed shaft hole, fixed shaft hole week on be equipped with the positioning groove that three curved runs through.

As a preferred embodiment of the invention, the fixed basal disc is made of ABS engineering plastics.

The fixing device of the paper pressing wheel greatly facilitates the installation of the paper pressing wheel by utilizing the fixing shaft hole in the center of the fixing base disc and the three arc-shaped positioning clamping grooves in the circumferential direction of the fixing shaft hole. Due to the adoption of bilateral drive, the stability of the paper pressing wheel under high-speed rotation is greatly improved. The fixing device for the paper pressing wheel is simple in structure, convenient to use and high in practicability.
