The paper feeding path structure 10 provided in the present embodiment is described in detail below with reference to fig. 1 to 8.

Referring to fig. 1, the present embodiment provides a paper feeding passage structure 10, including: the paper feeding device comprises a base 100, wherein the base 100 is provided with a paper feeding channel 110, and two side walls of the paper feeding channel 110 are a first side wall 111 and a second side wall 113 respectively; the paper feeding device comprises a first blocking member 200 and a second blocking member 300, wherein the first blocking member 200 and the second blocking member 300 are respectively arranged on two sides of the paper feeding channel 110, the first blocking member 200 is used for preventing printing paper from being scraped into the first side wall 111, and the second blocking member 300 is used for preventing printing paper from being scraped into the second side wall 113.

Specifically, the paper feeding path 110 includes a first side wall 111, a bottom wall 112, and a second side wall 113 connected in sequence. The printing paper passes between the first side wall 111 and the second side wall 113, and moves towards the printing roller 20 and the printing head.

Specifically, when the printing paper passes through the paper feeding channel 110, two side edges of the printing paper wear the first side wall 111 and the second side wall 113 respectively, a gap is drawn between the first side wall 111 and the second side wall 113 due to long-term wear, and the printing paper is easily clamped into the gap during subsequent paper feeding, thereby causing paper jam. The first blocking member 200 is arranged on one side of the first side wall 111, and the first blocking member 200 can prevent the printing paper from being scraped into the first side wall 111 in the moving process, so that a gap is prevented from being scraped from the first side wall 111, and the paper jam phenomenon can be avoided. Similarly, the second blocking member 300 can prevent the printing paper from being scraped into the second sidewall 113 during the moving process, so as to avoid a gap from being scraped on the second sidewall 113, thereby preventing the paper jam from occurring.

In this embodiment, the first blocking member 200 is at least partially adjacent to the second sidewall 113 relative to the first sidewall 111, and the second blocking member 300 is at least partially adjacent to the first sidewall 111 relative to the second sidewall 113.

"at least partially" includes both partially and fully. The phrase "the first blocking member 200 is at least partially close to the second sidewall 113 relative to the first sidewall 111" means that the first blocking member 200 is partially or completely close to the second sidewall 113 relative to the first sidewall 111, that is, a part or a whole of the first blocking member 200 is located between the first sidewall 111 and the second sidewall 113, so as to block printing paper from being scraped into the first sidewall 111. Similarly, the second blocking member 300 is partially or entirely located between the second sidewall 113 and the first sidewall 111, and can block the printing paper from being scraped into the second sidewall 113.

The shapes and arrangement of the first barrier 200 and the second barrier 300 at least include the following:

referring to fig. 1, in the present embodiment, the first blocking member 200 and the second blocking member 300 are both of a columnar structure. Specifically, the first blocking member 200 and the second blocking member 300 are disposed on the housing 100 in a direction parallel to the first sidewall 111.

Referring to fig. 2, the first blocking member 200 has a first circumferential surface; the first circumferential surface portion protrudes with respect to the first sidewall 111. The second blocking member 300 has a second circumferential surface, a second circumferential surface portion protruding with respect to the second sidewall 113. The printing paper passes between the first barrier member 200 and the second barrier member 300 without scratching the first sidewall 111 and the second sidewall 113.

Referring to fig. 3, the first circumferential surface is tangential to the plane of the first sidewall 111. The second circumferential surface is tangential to the plane of the second sidewall 113. The printing paper can contact with the first and

second sidewalls

111 and 113, but due to the blocking effect of the first and second circumferential surfaces, the printing paper cannot be scraped into the first and

second sidewalls

111 and 113, so that the wear resistance of the paper feeding path 110 can be improved.

Referring to fig. 4, in the present embodiment, the first blocking member 200 and the second blocking member 300 are both prism structures. May be a triangular prism, a quadrangular prism or a pentagonal prism. In this embodiment, the first barrier 200 and the second barrier 300 are quadrangular prisms.

Referring to fig. 4 and 5, in the present embodiment, the first blocking member 200 has a first blocking surface for contacting the printing paper; the first blocking surface is adjacent to the second sidewall 113 opposite to the first sidewall 111. The second barrier 300 has a second barrier face for contacting the printing paper; the second blocking surface is adjacent to the first sidewall 111 opposite to the second sidewall 113.
