[0026] The first cleaning component 6 includes a dust hood 601 mounted to the front end of the support plate 3. A five-way pipe 602 is mounted on the top of the dust hood 601. A first connecting rod 603 is rotatably mounted through the front end of the dust hood 601. A first gear 604 and a brush roller 605 are mounted sequentially from front to back on the outer wall of the first connecting rod 603.

[0027] The paper feeding assembly 8 includes a geared motor 801 mounted at the rear end of the support plate 3. A second connecting rod 802 is mounted at the output end of the geared motor 801. A second gear 803 and a paper feeding roller 804 are mounted sequentially from front to back on the outer wall of the second connecting rod 802.

[0028] In this embodiment, as Figure 3 and Figure 6 As shown, the static eliminator 9 includes a base plate 901 mounted on the front end of a support plate 3. A rectangular groove is formed on the top of the base plate 901, and a metal plate 902 is installed inside the rectangular groove. A metal wire 903 is installed on the bottom of the metal plate 902. The internal dimensions of the rectangular groove are consistent with the external dimensions of the metal plate 902. One end of the metal wire 903 is connected to the ground. When the printing paper passes through the metal plate 902, the static electricity on the printing paper is conducted to the ground through the metal plate 902 and the metal wire 903, which can prevent the printing paper from being attracted by static electricity and causing paper jams.

[0029] In this embodiment, as Figure 3 and Figure 6 As shown, the support plate 3, electric push rod 13 and guide block 14 are symmetrically distributed about the vertical center line of the base plate 901; by using a synchronizer to control the simultaneous start of the two electric push rods 13, the distance between the two guide blocks 14 can be adjusted, which can guide the printing paper.

[0030] In this embodiment, as Figure 3 and Figure 4 As shown, the brush roller 605 forms a rotating mechanism with the first gear 604 via the first connecting rod 603. The first connecting rod 603 is rotatably mounted through the front end of the support plate 3. The outer wall dimensions and structures of the first cleaning component 6 and the second cleaning component 7 are consistent. When the first gear 604 rotates, it drives the brush roller 605 to rotate via the first connecting rod 603. The rotation of the brush roller 605 can clean the surface of the printing paper and prevent dust adhering to the printing paper from affecting the printing effect.

[0031] In this embodiment, as Figure 3 and Figure 5As shown, the second gear 803 and the paper feed roller 804 form a rotating mechanism with the reduction motor 801 through the second connecting rod 802. The second connecting rod 802 is rotatably mounted through the front end of the support plate 3. When the reduction motor 801 starts, it drives the second gear 803 and the paper feed roller 804 to rotate through the second connecting rod 802, so that the paper feed roller 804 can pick up the printing paper from the paper tray.

[0032] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the first gear 604 on the first cleaning component 6 and the first gear 604 and second gear 803 on the second cleaning component 7 are both meshed with the inner wall of the toothed belt 12. When the second gear 803 rotates, it drives the first gear 604 on the first cleaning component 6 and the first gear 604 on the second cleaning component 7 to rotate through the toothed belt 12. The rotation of the first gear 604 on the first cleaning component 6 drives the brush roller 605 on the first cleaning component 6 to rotate through the first connecting rod 603 on the first cleaning component 6, thus cleaning the surface of the printing paper. The rotation of the first gear 604 on the second cleaning component 7 drives the brush roller 605 on the second cleaning component 7 to rotate through the first connecting rod 603 on the second cleaning component 7, thus cleaning the surface of the paper feed roller 804. This prevents excessive dust from adhering to the surface of the paper feed roller 804, which would affect the paper feeding effect and cause paper jams.

[0033] In this embodiment, as Figure 3 and Figure 4 As shown, the bottom two ends of the three-way pipe 5 are connected to the five-way pipe 602 at the top of the first cleaning component 6 and the second cleaning component 7, respectively. The air outlet of the fan 4 is equipped with a dust collection bag. When the fan 4 is started, the dust raised by the brush roller 605 is sucked up through the three-way pipe 5, the five-way pipe 602 on the first cleaning component 6, the five-way pipe 602 on the second cleaning component 7 and the dust suction hood 601. Then the dust is sent into the dust collection bag, which can prevent the dust raised by the brush roller 605 from falling back onto the printing paper.

[0034] The usage and advantages of this utility model: The small printer with anti-paper jam function operates as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, firstly, the fan 4 and the geared motor 801 are started. The geared motor 801 drives the second gear 803 and the paper feed roller 804 to rotate via the second connecting rod 802. The paper feed roller 804 picks up the printing paper from the paper tray. The second gear 803 drives the first gear 604 on the first cleaning assembly 6 and the second cleaning assembly 7 to rotate via the toothed belt 12. The rotation of the first gear 604 on the first cleaning assembly 6 drives the brush roller 605 on the first cleaning assembly 6 to rotate via the first connecting rod 603 on the first cleaning assembly 6. The rotation of the first gear 604 on the second cleaning assembly 7 drives the brush roller 605 on the first cleaning assembly 6 to rotate via the first connecting rod 603 on the first cleaning assembly 6. The first connecting rod 603 on the second cleaning component 7 drives the brush roller 605 on the second cleaning component 7 to rotate, cleaning the surface of the paper feed roller 804. When the printing paper passes through the metal plate 902, the static electricity on the paper is conducted to the ground through the metal plate 902 and the metal wire 903. The brush roller 605 on the first cleaning component 6 rotates to clean the surface of the paper. At the same time, the fan 4 sucks up the dust raised by the brush roller 605 through the three-way pipe 5, the five-way pipe 602 on the first cleaning component 6, the five-way pipe 602 on the second cleaning component 7 and the dust suction hood 601.
