Description
Technical field
The utility model relates to the strainers in printer carton paper feeding mechanism.
Background technique
With reference to Fig. 1, existing paper feed mechanism of printer generally comprises motor 1, intake roller 2, exit roller 3, paper feed 2, synchronous belt
7,2 one end of intake roller connects paper feed roller gear 4, and 3 one end of exit roller connects paper delivery roller gear 5, and 7 both ends of synchronous belt are connected to
On paper feed roller gear 4 and paper delivery roller gear 5, motor 1 drives intake roller 2 to move, and makes 2 He of intake roller by the connection of synchronous belt 7
Exit roller 3 moves synchronously.
With reference to Fig. 1, the strainer in existing paper feed mechanism of printer includes torque arm spring 8, belt transmission bracket 10,
8 both ends of torque arm spring are both secured in belt transmission bracket 10；The disadvantage is that the distance between tensioning wheel and belt transmission bracket 10 L
Tensioning wheel 6 can (be in circle in the plane in the line direction of intake roller 2 and exit roller 3 perpendicular to X-direction in the case where bigger
The shaking of all types, it is unstable.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned insufficient of the prior art and provide a kind of printer
Strainer in paper feeding mechanism keeps its tensioning more stable.
The technical scheme in the invention for solving the above technical problem are as follows:
Strainer in paper feed mechanism of printer, comprising:
Axle sleeve is arranged in torque arm, one end, and axle sleeve is covered on paper delivery roller gear and can be rotated each other, the setting of the torque arm other end
Tension wheel shaft, tension wheel shaft support tensioning wheels；
Torque arm spring, one end are fixed on toothed belt transmission bracket, on the other end of the fixed torque arm of the other end；
Tensioning wheel is removably secured in torque arm, is pressed on synchronous belt；
Synchronous belt, both ends are connected on paper feed roller gear and paper delivery roller gear, make intake roller fortune synchronous with exit roller
It is dynamic.
Preferably, the direction of the torque arm spring and is placed on intake roller and exit roller perpendicular to the center line of torque arm
Between medium position on, it is more stable in this way.
Preferably, support portion is set in the middle part of the torque arm, support portion is resisted against in belt transmission bracket, torque arm by with skin
The contact of V belt translation bracket and limit, moreover it is possible to prevent the shaking of torque arm to increase its stability.
Preferably, torque arm axle sleeve covers on paper delivery roll sleeve, and paper delivery roll sleeve covers on paper delivery roller gear, paper delivery roller gear
It is fixed on exit roller.
Utility model has the advantages that due to setting torque arm and torque arm one end is connected on tensioning wheel, the other end connects
It connects on exit roller, and torque arm spring one end is fixed on toothed belt transmission bracket, on the other end of the fixed torque arm of the other end,
Synchronizing wheel can smoothly be connected by torque arm and torque arm spring in this way, therefore, tension structure is more stable.

Specific embodiment
With reference to the accompanying drawing, the utility model is described in further detail for embodiment.
As shown in Figure 1, the strainer in paper feed mechanism of printer, including torque arm 9, tensioning wheel 6, torque arm spring 8, paper feed
Roller 2, exit roller 3, synchronous belt 7.
As shown in Fig. 3,5,9 one end of torque arm be arranged axle sleeve 91, torque arm 9 by axle sleeve 91 be fixed on paper delivery roll sleeve 12 and around
It is rotated, and paper delivery roll sleeve 12 is fixed on paper delivery roller gear 5 by hole axle cooperation, on paper delivery roller gear 5 and exit roller 3 between it is logical
It crosses hole axle cooperation and fixes and have buckle 121, also there is limit 122 in direction of rotation, therefore exit roller 3 and paper delivery roller gear 5 are combined into one
A entirety, moves together.
Tension wheel shaft 93,93 support tensioning wheels 6 of tension wheel shaft are arranged in 9 other end of torque arm.
9 other end of torque arm also sets up the fixed part 92 of torque arm spring 8, this is fixed in one end of torque arm spring 8.
Support portion 94 is arranged in 9 middle part side of torque arm, and support portion 94 is resisted against in belt transmission bracket 10, belt transmission bracket
10 are fixed on the bottom (being not drawn into figure) of printer body, could be secured on the other component of printer body, and torque arm 9 is logical
It crosses and is limited with the contact of belt transmission bracket 10, moreover it is possible to prevent the shaking of torque arm to increase its stability.
As shown in Figure 1, 2,8 one end of torque arm spring is fixed in belt transmission bracket 10, in the fixed torque arm 9 of the other end.
The direction of torque arm spring 8 and is placed between intake roller 2 and exit roller 3 perpendicular to the center line of torque arm 9
On portion position.
As shown in figure 4, tensioning wheel 6 is fixed on 9 torque arm tension wheel shafts 93 by hole axle cooperation, can and be only capable of around torque arm
9 tension wheel shaft 93 rotates, and tensioning wheel 6 is pressed in synchronous belt 7, is tensioned synchronous belt 7.
7 both ends of synchronous belt are connected on paper feed roller gear 4 and paper delivery roller gear 5, keep intake roller 2 and exit roller 3 same
Step movement.
