The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the utility model be described in further detail.
As shown in Fig. 1 ~ 5, a kind of printer rubber roller pressure switching mechanism, comprise printer support 1 and front, back cot (2, 3), the rear side of the front side of described front rubber roll 2 and back cot 3 is parallel is respectively provided with front switching rotating shaft 4 and rear switching rotating shaft 5, before described, rear switching rotating shaft (4, 5) on, be provided with vertically respectively several breach (6, 7), in described frame 1, be positioned at the front side of front switching rotating shaft 4 and the rear side of rear switching rotating shaft 5 be respectively arranged with along with switch that the axial equidirectional of rotating shaft is arranged and with described breach (6, 7) the corresponding spring silk 8 in position, described spring silk 8 is through described breach (6, 7) after, its afterbody is pressed on corresponding rubber roll (2, 3) rubber roller top, rubber roller is after receiving the pressure of spring silk 8, make the frictional force between rubber roll and print media become large.
In the present embodiment, two adjacent spring silks 8 are by fixed card, to be connected to the two ends that a spring silk in frame 1 stretches out to be formed, the spring silk 8 that is positioned at frame 1 front side is stuck in frame front side by bending, and the spring silk 8 that is positioned at frame 1 rear side is fixed on the trailing flank of frame rear wall and fixes by screw.
In the present embodiment, described breach (6, 7) comprise the breach A (6) of at least one and the breach B (7) of at least one, the bottom surface of described breach A (6) and breach B (7) at grade, before described, rear switching rotating shaft (4, 5) front side of the breach B (7) on is provided with inclined-plane otch 9 in order to front, rear switching rotating shaft (4, 5) after rotation, the corresponding spring silk 8 of forward edge jack-up of described breach A (6) makes its afterbody depart from corresponding rubber roller, breach B (7) is owing to being provided with inclined-plane otch 9, therefore the spring silk 8 that breach B (8) locates can continue to be pressed on corresponding rubber roller top, because the spring silk 8 of rubber roller pressurized tails off, thereby play the effect that reduces pressure.
When print media enters from printer front side, rubber roll (2,3) needs larger pressure, and print media is when enter from printer rear side, and rubber roll (2,3) pressure can be smaller.
In the present embodiment, the sidepiece of described frame 1 is provided with slide block 10, on the end of described forward and backward switching rotating shaft (4,5) and described slide block 10 homonymies, be fixed with respectively the fork 11 that is positioned at slide block 10 tops, the corresponding position of described slide block 10 upsides and described two forks 11 is respectively equipped with when protuberance 12 slides in order to slide block 10 and touches forks 11 so that described forward and backward switching rotating shaft (4,5) is rotated by protuberance 12.
In the present embodiment, described slide block 10 middle parts are provided with chute 13, described frame 1 sidepiece is provided with the protruding pin 14 through chute 13, the bottom of described slide block 10 is provided with tandem a pair of draw-in groove 15, described frame 1 sidepiece is positioned at slide block 10 belows and is provided with the latch 16 that can be absorbed in draw-in groove 15, and latch 16 is stuck in draw-in groove 15 and resets with restriction slide block 10.
Printer rubber roller pressure switching mechanism in the present embodiment, when slide block 10 reach, latch 16 is stuck in rear draw-in groove, fork 11 is clockwise rotated by jack-up, forward and backward switching rotating shaft (4,5) also clockwise rotates, the spring silk 8 that the forward edge jack-up breach A (6) of the upper breach A (6) of forward and backward switching rotating shaft (4,5) locates, the spring silk 8 of rubber roller pressurized is tailed off, thereby pressure diminishes; While moving after slide block 10, latch 16 is stuck in front bayonet slot, and fork 11 is put down, forward and backward switching rotating shaft (4,5) turning anticlockwise, and spring silk 8 is smoothly through breach A and breach B, and all spring silks 8 are all pressed on rubber roller, make rubber roll pressure become large.
