A printer lower paper guide assembly

Abstract

The invention discloses a lower paper deflector component of a printer. The lower paper deflector component of the printer comprises a print board rib, a front paper deflector and a rear paper deflector, wherein the front paper deflector and the rear paper deflector are located on two sides, along the direction of paper feeding, of the print board rib, installation holes and installation pillars are arranged on the left side walls and the right side walls of the front paper deflector and the rear paper deflector, the print board rib, the front paper deflector and the rear paper deflector are integrated in an injection molding mode, the print board rib is located on a paper deflecting plane and higher than the front paper deflector and the rear paper deflector, and smooth transition is located between the print board rib and the front paper deflector and between the print board rib and the rear paper deflector. According to the lower paper deflector component of the printer, the print board rib, the front paper deflector and the rear paper deflector are integrated in an injection molding mode, so that the phenomenon of paper clamping which is caused by that a print medium crimps or warps so as to be clamped into gaps of the paper deflecting plane in the process of printing is completely avoided, paper waste caused by the phenomenon of the paper clamping is reduced, and printing efficiency is improved. In addition, the print board rib is adopted to serve as a print working plane to replace a print roller of a traditional technology, so that distances from a printing head to the any positions of the print working plane are the same, when printing is conducted, ink marks on the print medium are even, and printing quality is improved effectively.

Description

technical field [0001] The invention relates to a printer lower paper guide assembly. Background technique [0002] like Figure 1~Figure 2 shown, where figure 1 The direction indicated by the arrow in the middle is the paper feed direction of the printer. The lower paper guide assembly of the printer in the traditional technology includes a front paper guide 1', a rear paper guide 2', and a printing roller 3'. The printing roller 3' is installed on the left and right brackets of the printer. On the top, the front and rear paper guides 1', 2' are located on both sides of the printing roller 3', the front and rear paper guides 1', 2' are set separately and connected by buckles. The front and rear guides of this structure There will be gaps between the cardboard 1', 2' and the printing roller 3' and the connection between the front and rear paper guide plates 1', 2'. The existence of this gap will cause the front edge of the printing medium to curl or It is tilted and stuck...
