Abstract
A kind of paper feeding mechanism of printer, including paper-sheets rolling wheel, paper supporting element accommodate and support paper；Friction pad is placed on the paper supporting element on paper-sheets rolling wheel opposite, friction pad support portion, supports friction pad, elastic connection is on paper supporting element.Utility model has the advantages that since friction pad support portion elastic connection is on paper supporting element, in this way when the paper on paper supporting element remains last, under the pressure effect of paper-sheets rolling wheel, friction pad support portion generates deformation, the pressure being applied on friction pad is set to change, to change the frictional force between paper and friction pad, therefore, paper-sheets rolling wheel remains to overcome the frictional force between friction pad and paper and moves forward last paper, realizes normal paper supply.
Description
Technical field
The utility model relates to a kind of paper feeding mechanisms of printer.
Background technique
Existing printer paper-feeding mechanism refers to Fig. 1 comprising accommodates the paper supporting element 1, paper-sheets rolling wheel 3, opposite stranding of paper 4
The friction pad 2 on paper supporting element 1 is arranged in 3 contact position of paper wheel, and paper-sheets rolling wheel 3 is by squeezing paper 4 using the friction of itself and paper 4
Power and paper is fed forward.
But existing paper-feeding mechanism has the following problems:
1. if friction coefficient μ 2 between friction pad 2 and paper 4 is greater than the friction coefficient μ 1 of paper-sheets rolling wheel 3 and paper 4,
It then can not be towards paper feed direction paper feeding when last paper 4.
2. it is also different from the friction coefficient μ 2 of friction pad 2 since 4 type of paper is different, therefore, it may appear that bigger rubs
Coefficient μ 2 is wiped, then will appear more problems, i.e., existing paper feeding structure limits its use scope for adapting to paper.
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
Paper feeding mechanism, the frictional force between friction pad and last paper can be changed, so as to smooth delivery of power last
Paper.
The technical scheme in the invention for solving the above technical problem are as follows:
A kind of paper feeding mechanism of printer, comprising:
Paper-sheets rolling wheel,
Paper supporting element accommodates and supports paper；
Friction pad is placed on the paper supporting element on paper-sheets rolling wheel opposite,
Friction pad support portion supports friction pad, and elastic connection is on paper supporting element.
Preferably, above-mentioned friction pad support portion is a part of paper supporting element, will surround the part hollow out of friction pad, in this way
Manufacture is more convenient.
Utility model has the advantages that since friction pad support portion elastic connection is on paper supporting element, in this way when paper branch
When paper in support member remains last, under the pressure effect of paper-sheets rolling wheel, friction pad support portion generates deformation, makes to be applied to friction
Pressure on pad changes, to change the frictional force between paper and friction pad, therefore, paper-sheets rolling wheel remains to overcome friction pad
Frictional force between paper and move forward last paper, realize normal paper supply.
Detailed description of the invention
Fig. 1 is a kind of side structure schematic diagram of the paper feeding mechanism of printer of the utility model embodiment.
Fig. 2 is a kind of stereoscopic schematic diagram of paper feeding mechanism of printer of the utility model embodiment (omitting paper-sheets rolling wheel).
Specific embodiment
With reference to the accompanying drawing, the utility model is described in further detail for embodiment.
As shown in Figure 1, 2, a kind of paper feeding mechanism of printer, comprising: paper-sheets rolling wheel 3, paper supporting element 1, friction pad 2.
Paper-sheets rolling wheel 3 is placed in the top of paper supporting element 1, is squeezed by paper-sheets rolling wheel 3, friction paper 4, by paper 4 from paper supporting element
1 is fed forward, and is not changed in the present embodiment to paper-sheets rolling wheel 3.
Paper supporting element 1, wherein opposite 3 contact position of paper-sheets rolling wheel is equipped with the region 11 for placing friction pad 2, friction pad 2 is placed in this
On region 11, the equal hollow out 12 in 11 periphery of region, such region 11 can be bent downwardly deformation under the extruding of paper-sheets rolling wheel 3.
In the present embodiment, friction pad 2 is arranged two pieces, and horizontal alignment interval comes on paper supporting element 1, can also according to circumstances really
Surely the quantity being arranged, and the quantity of paper-sheets rolling wheel 3 is accordingly set.
