Description
Technical field
The utility model relates to a kind of printer engine, particularly relates to a kind of thermal printing machine core.
Background technology
At present, there is following shortcoming in the thermal printing machine core: main support is a straight trough, is fixed manufacturing, installation cost height with spring; The turning cylinder of printer engine is two dops, and trouble is installed; The positive not location of heating plate backing plate causes spring to come off; Printer engine motor mounting part position and main support disconnect, intensity difference; The mounting hole site of printer engine is few, has limited the mounting means of printer engine etc.
In addition, the thermal printing machine core also exists: main support is made up of support and paper guiding sheet two parts, and is loosely organized, so that trouble is installed, and assembly cost is too high.Heating plate backing plate side is the location not, so that the poor location of heating board assembly when rotating on main support.Be used for protecting the dust cap of gear train to seal, can't clean after dust enters, thereby quickened the wearing and tearing of gear.
The utility model content
Because above-mentioned disappearance drawback, the utility model people thinks that it has necessity anxious to be corrected.Main purpose is: collude structures such as groove, turning cylinder dop, the positive location of heating plate backing plate, motor and main support installation position, mounting hole site and main support, heating plate backing plate side positioning element, dust cap by the main support that improves printer engine, simplify the printer engine structure to reach, reduce manufacturing, installation steps, add strong fix, the convenient cleaning improved purposes such as printer engine bulk strength.
The utility model is realized by following technical scheme:
This printer engine mainly comprises: main support 1, heating board assembly 2, motor 3, gear train 4, dust cap 5, turning cylinder 6, paper feed rubber roll assembly 7 and spring 8 etc.Wherein heating board assembly 2 is made of heating plate and heating plate backing plate.Have metal column for gear train 4 usefulness to be installed on main support 1 the right wall, gear train 4 is made of 4 grades of gear graduations, and whole gear train 4 is blocked by a dust cap 5, and dust cap 5 is fixed on the main support 1 by locating hole.Two concentric axis holes are arranged on the left and right sides metallic walls of main support 1, pass turning cylinder 6 heating board assembly 2 is installed on the main support 1.It is characterized in that: two concentric circle or semicircular overhead kick grooves are arranged on the left and right sides metallic walls of main support 1, and this is fixing paper feed rubber roll assembly 7 usefulness.It is the simple and easy master mode movement of going up that semicircular overhead kick groove makes printer engine, that is, the paper feed rubber roll can freely take off paper on the convenience.When it is concentric bowlder, can make the simple and easy master mode movement of going up become fixing printer engine.Turning cylinder 6 one ends are step, and the other end is fixed on axle on the main support 1 by circlip.There is a crimping main support 1 back, has two baby hems, two projectioies on heating plate backing plate front to form the location of spring thereon, leaves the cannelure that the printer data winding displacement exports on this crimping.Motor 3 is contained on the right wall of main support 1, and an oblique looping pit is arranged on the wall, the usefulness of stepping down when installing for motor 3.
Heating plate is bonded on the heating plate backing plate, and the heating plate backing plate has two salient points on the side, the positioning action a when heating board assembly 2 rotates on main support 1.
The bottom surface of dust cap 5 is to reveal sky, is beneficial to cleaning, blowdown.
More than several improve that technical schemes can be implemented separately or several implement simultaneously, also can all implement, all to be embodied as preferred version.
The contrast prior art, the utility model changes the main support of printer engine into two concentric circle or metal overhead kick grooves, saves with spring and fixes, and has reduced manufacturing, installation cost.Turning cylinder changes single clamp into, prevents landing with step, the convenient installation.There are two projectioies in heating plate backing plate front, can prevent that spring from coming off with two baby hems on the main support 1 back crimping.The printer engine main support is installed the position of motor, increases by a looping pit, in proof strength, installs more convenient.Increased mounting hole site and two little draw-in grooves of a printer engine, increased the mounting means of printer engine, made printer engine that the back is installed and use wider.
In addition, the utlity model has: the main support unitary piece of metal is one time punching molded, and compact conformation is easy for installation.There are two salient points heating plate backing plate side, the positioning action a when heating board assembly rotates on main support.Being used for protecting the dust cap of gear train is to reveal sky, is beneficial to cleaning, blowdown, has reduced the advantages such as wearing and tearing of gear.
