1. Technical Field
The present disclosure relates to feeding apparatuses, and more particularly to a paper feeding apparatus of a printer.
2. Description of Related Art
Printers are often equipped with rollers to feed paper or other printable material into a printing area of the printer. Unfortunately, the printable material often gets wrapped around one or more rollers and jams the system.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
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.”
The bracket 10 includes a supporting surface 11. A row of blocking pins 13 and a row of restricting pieces 14 are located on the supporting surface 11. The row of blocking pins 13 is parallel to the row of restricting pieces 14. Each of the row of the blocking pins 13 includes a cambered surface 131 which faces to the row of restricting pieces 14. A receiving room 16 is defined between the row of blocking pins 13 and the row of restricting pieces 14.
A pair of supporting plates 15 are located on the supporting surface 11. Each of the pair of supporting plates 15 defines a pivot hole 151.
Opposites ends of the first feeding shaft 30 can be inserted in the pivot holes 151 of the pair of supporting plates 15. A plurality of first feeding rollers 33 and a plurality of fans 31 are in a staggered arrangement on the first feeding shaft 30. One of the plurality of fans 31 is located between two of the plurality of first feeding rollers 33. One of the plurality of first feeding rollers 33 is located between two of the plurality of fans 31. The plurality of first feeding rollers 33 and the plurality of fans 31 are rotatable together with the first feeding shaft 30.
The second feeding shaft 50 can be pivotally mounted in the receiving room 16. A plurality of second feeding rollers 53 are mounted on the second feeding shaft 50. In one embodiment, the plurality of first feeding rollers 33 and the plurality of second feeding rollers 53 are made of rubber, which can generate large friction force to conveniently feed papers.
