DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, a cleaning apparatus for a printer includes a bracket 10 and a paper transmitting apparatus 30. The bracket 10 is mounted on a printer.
Referring to FIGS. 1 and 2, the bracket 10 includes a first board 11 and a second board 13 perpendicular to the first board 11. A paper tray 14 is mounted on the first board 11. A plurality of papers 50 is located on the paper tray 14. The second board 13 defines an opening 131. The opening 131 is aligned with the paper tray 14. The paper tray 14 defines a pair of cutouts 141. The first board 11 defines a pair of receiving rooms 112 corresponding to the pair of cutouts 141. The receiving rooms 112 are located below and aligned with the cutouts 141. Two sides of each receiving room 112 define a pair of pivot holes 113. Each receiving room 112 can receive a brush 40 therein.
Referring to FIG. 3, the brush 40 includes a columnar main body 41. A pair of pivot pins 42 is formed on two ends of the main body 41. A plurality of bristles 43 is secured on the main body 41.
Referring to FIG. 1, the paper transmitting apparatus 30 includes a carrier 31. A rear portion of the carrier 31 is pivotably mounted on the printer. A roller 32 is pivotably mounted on a front portion of the carrier 31. Two sleeves 35 are fit on the roller 32. Outer surfaces of the sleeves 35 are rough. A motor (not shown) is mounted on the paper transmitting apparatus 30. A plurality of gears 34 is linked between the roller 32 and the motor. The motor rotates the roller 32 via the gears 34. The sleeves 35 rotate together with the roller 32.
Referring to FIGS. 1 to 7, in assembly of the cleaning apparatus, the brush 40 is placed in the receiving room 112. The pivot pins 42 are received in the pivot holes113 to mount the brush 40 in the receiving room 112. Then, the rear portion of the carrier 31 is pivotably mounted on the printer. The paper transmitting apparatus 30 rotates on the printer between a first position and a second position. In the first position, the roller 32 is located above the paper tray 14 and does not contact with the paper tray 14. In the second position, the sleeves 35 of the roller 32 are aligned with the cutouts 141.
When the paper transmitting apparatus 30 is positioned in the second position, if there is a paper 50 located on the paper tray 14, the sleeves 35 come in contact with the paper 50. To move the paper 50, the motor rotates the roller 32. The sleeves 35 rotate to bring the paper 50 slide on the paper tray 14. Paper scraps of the paper 50 are left on the sleeves 35. The paper 50 slides in the opening 131 to move in the printer. If there is not a paper 50 located on the paper tray 14, the sleeves 35 rotate against the bristles 43 to be cleaned of any paper scraps.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
