In order to avoid the above problem, in this embodiment, the dust-proof assembly 2 further includes a roller 25, one end of the roller 25 is mounted at the second end of the first connecting rod 23, the other end of the roller 25 is mounted at the second end of the second connecting rod 24, the periphery of the dust-proof assembly 22 near the paper guide 12 is connected to the peripheral wall of the roller 25, and the peripheral wall of the roller 25 is also spaced from the surface of the paper guide 12.

Specifically, the roller 25 can be reciprocally rotated by a small margin between the first connecting lever 23 and the second connecting lever 24, so that smoothness of movement of the printing paper between the outer peripheral wall of the roller 25 and the outer wall surface of the paper guide plate 12 is ensured.

After a period of use, the user needs to clean dust, mosquitoes, flies, etc. on the dust screen 22, and in order to improve the convenience of the user in removing the dust screen 22, in some embodiments, the first connecting rod 23 and the second connecting rod 24 are both adhesively connected to the dust screen 22.

In specific implementation, the periphery of the dust screen 22 can be assembled with the hook surface of the hook-and-loop fastener, then the hook surface of the hook-and-loop fastener is arranged on the first connecting rod 23 and the second connecting rod 24, and the purpose of bonding the dust screen 22 on the first connecting rod 23 or the second connecting rod 24 can be achieved based on bonding and matching between the hook surface and the hook surface.

In order to facilitate the user to adjust the gap between the roller 25 and the paper guide 12, in this embodiment, the first end of the first connecting rod 23 and the first end of the second connecting rod 24 are both rotatably connected with the fixing frame 21, so that the position of the dust screen 22 in the paper feeding channel 13 is adjustable.

Because the dustproof component 2 of the product is used as an auxiliary component of the existing printer, in order to facilitate the dustproof component 2 to be applied to the machine body 1 of the existing various printers and improve the disassembly and assembly convenience of the dustproof component 2, preferably, the fixing bracket comprises a transverse plate 211, a first vertical rod 212 and a second vertical rod 213, the first vertical rod 212 and the second vertical rod 213 are arranged at two opposite ends of the transverse plate 211, the first vertical rod 212 and the second vertical rod 213 extend along the height direction of the machine body 1, the first end of the first connecting rod 23 is rotatably arranged on the first vertical rod 212, and the first end of the second connecting rod 24 is rotatably arranged on the second vertical rod 213; wherein the cross plate 211 is adhesively connected to the inner wall surface of the top wall 11. Of course, the design of the present application is not limited thereto, and in other embodiments, the transverse plate 211 may be fixed to the top wall 11 by a magnetic connection.

When the first connecting rod 23 and the second connecting rod 24 are both rotatably mounted on the fixing frame 21, as the dust screen 22, the first connecting rod 23, the second connecting rod 24, the roller 25 and other components have a certain weight, the first connecting rod 23 and the second connecting rod 24 can both rotate and drive the roller 25 to descend to a position abutting against the paper guide plate 12, which is not beneficial to smooth movement between the paper guide plate 12 and the roller 25, in order to solve the above problems, specifically, an elastic member 26 is further disposed between the first vertical rod 212 and the second vertical rod 213, the elastic member 26 is disposed on one side of the dust screen 22 facing away from the paper inlet 111, and the elastic member 26 is formed with a convex arc surface 261 abutting against the dust screen 22. In this way, the elastic member 26 abutting against the dust-proof net 22 can support the dust-proof net 22, prevent the dust-proof net from excessively lowering the roller 25, and further ensure that a gap for smooth movement of the printing paper can be formed between the roller 25 and the paper guide plate 12.

In addition, the elastic member 26 can effectively support dust, mosquitoes, flies and other sundries falling on the dust screen 22, which is beneficial to improving the dust-proof effect of the product.

In particular embodiments, the elastic member 26 is an elastic pad (e.g., a sponge pad, a silica gel pad, a rubber pad, etc.) made of a flexible material. In some embodiments, the elastic member 26 may also be a sheet of elastic steel. Since there are a wide variety of embodiments of the elastic member 26, this is not specifically exemplified herein.

In particular embodiments, the adjustment member 27 is an adjustment bolt threadedly coupled to the first vertical rod 212. When the adjusting bolt is screwed into the machine body 1, the elastic piece 26 can be gradually extruded, so that the protruding height of the protruding arc surface 261 formed by the elastic piece 26, which protrudes towards the dust screen 22, is gradually increased, the dust screen 22 is effectively propped against and can be moved upwards, and the roller 25 is driven to move away from the paper guide plate 12.

When the adjusting bolt is screwed out of the machine body 1, the elastic piece 26 can be released, so that the protruding height of the protruding arc surface 261 formed by the elastic piece 26 towards the dust screen 22 is gradually reduced, the propping effect on the dust screen 22 is effectively reduced, the dust screen 22 can be moved downwards, and the roller 25 is driven to move towards the direction close to the paper guide plate 12.

It should be noted that the design of the present application is not limited thereto, and in other embodiments, the adjusting member 27 may be a pull rod that is disposed on the first vertical rod 212 in a pull manner, which is not limited herein.
