Abstract
Thermal printing head force of impression self adaptation installing mechanism, relates to thermal printing head.It is provided with thermal head installing plate, thermal head rotating shaft and 3 springs；Being provided with positioning supporting point in the middle part of described thermal head installing plate, thermal head installing plate is rotated centered by fixed pivot by thermal head rotating shaft；Thermal head installing plate both sides are provided with strip hole, thermal head installing plate can move along strip hole direction, for limiting the rotational freedom of thermal head installing plate, 3 springs are located on thermal head installing plate, thermal head passes through the phase tangent line of a fulcrum and roller bearing and thermal head, make to be evenly applied to about the power of 3 springs on thermal head heater wire, it is ensured that heater wire left and right, left and right uniform force.
Description
Technical field
This utility model relates to thermal printing head, especially relates to a kind of thermal printing head force of impression self adaptation installing mechanism.
Background technology
Mechanism's thermal head installing plate the most on the market is that thermal head rotating shaft passes 2 holes, and such fixed form requires thermal head
The bending position symmetry of installing plate is the highest, and guarantee rotating shaft is the most parallel with heater wire.The most under the force of a spring,
Thermal head fixed plate produces distortion, it is impossible to is fitted in equably on roller bearing, causes gradation of drop-out colour left-right deviation.
Summary of the invention
The purpose of this utility model is to provide a kind of thermal printing head force of impression self adaptation installing mechanism.
This utility model is provided with thermal head installing plate, thermal head rotating shaft and 3 springs；
Being provided with positioning supporting point in the middle part of described thermal head installing plate, thermal head installing plate passes through thermal head rotating shaft centered by fixed pivot
Rotate；Thermal head installing plate both sides are provided with strip hole, and thermal head installing plate can move along strip hole direction, is used for limiting temperature-sensitive
The rotational freedom of head installing plate, 3 springs are located on thermal head installing plate, and thermal head is by a fulcrum and roller bearing and warm
The phase tangent line (1 adds 1 line and determines the principle in face) of quick head so that be evenly applied to thermal head heating about the power of 3 springs
On line, it is ensured that the uniform force of heater wire left and right, left and right.
This utility model makes the quasiconductor heating element heats on printhead according to the operation principle of thermal printer and contacts temperature-sensitive and beat
Printing paper so that thermal printing paper variable color.The contact pressure of thermal printing paper and quasiconductor heating element heater affects the efficiency of heat transfer.
Being provided with positioning supporting point in the middle part of described thermal head installing plate, thermal head installing plate is rotated centered by fixed pivot by thermal head rotating shaft；
Thermal head installing plate both sides are provided with strip hole, and thermal head installing plate can move along strip hole direction, are used for limiting thermal head and install
The Z axis rotational freedom of plate.Thermal head of the present utility model adds the phase tangent line of roller bearing and thermal head by a fulcrum, and (1 adds 1
Line determines the principle in face) so that it is evenly applied to about the power of spring on thermal head heater wire, it is ensured that be subject to about the heater wire of left and right
Power is uniform, prints about solubility uniform.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of this utility model embodiment.
Fig. 2 is the side-looking structure composition schematic diagram of this utility model embodiment.
Detailed description of the invention
Seeing Fig. 1 and 2, this utility model is provided with thermal head installing plate 1, thermal head rotating shaft 2 and 3 springs 3；
Being provided with positioning supporting point A in the middle part of described thermal head installing plate 1, thermal head installing plate 1 is propped up with fixing by thermal head rotating shaft 2
Rotate centered by some A；Thermal head installing plate 1 both sides are provided with strip hole, and thermal head installing plate can move along strip hole direction,
For limiting the rotational freedom of thermal head installing plate 1,3 springs 3 are located on thermal head installing plate 1, and thermal head 4 passes through
The phase tangent line (1 adds 1 line and determines the principle in face) of one fulcrum and roller bearing 5 and thermal head 4 so that the power of 3 springs 3
Left and right is evenly applied on thermal head 4 heater wire, it is ensured that heater wire left and right, left and right uniform force.
