Description
Technical field
The present invention relates to printing equipment, particularly a kind of thermal head printing equipment that is applied on the medical equipment.
Background technology
Because the thermal head printing technique has that print speed is fast, print resolution is high, font is clear, long service life, noise is low and characteristics such as non-maintaining.Thereby, by each extensively utilization of field institute, particularly more extensive in the medical instruments field utilization, for example, when people arrived hospital's health check-up, the doctor need use the thermal printing apparatus on the Medical Devices, print waveform and come diagnostic analysis, judge examinee's physical condition with this, as seen, the utilization of printing equipment in medical field also plays a part very important.The thermal printing apparatus of on market, using at present, because thermal head can not remain on the same horizontal line with rubber-surfaced roll, also be difficult to remain constant compression force, in use for some time, will occur printing light and print paper jam phenomenon, reliability of products is reduced, and also be unfavorable for operation, brought great puzzlement and trouble to operating personnel.
Summary of the invention
The invention provides a kind of printing equipment, adopt self balancing thermal printing head, and in conjunction with corresponding structure design, solve in the prior art paperboard and print thin out technical problem.
The present invention comprises umbilicate shell component down for this printing equipment that provides is provided, be arranged at the print components in the described shell component intermediate recess space down, fasten the last shell component of assembling with described shell component down, the described shell component of going up has an opening, described print components partly is exposed in this opening, also comprise being hinged on the described printing door of going up on the shell component, described printing door fastens the described opening of going up shell component of sealing; Described printing door is provided with a rubber-surfaced roll, described print components comprises fixed head, holder, fixed mount, thermal head, described holder is fixed on the described fixed head, thermal head flexibly connects fixed mount, fixed mount and holder are hinged, print components also includes the elastic equilibrium mechanism that is used for the balance thermal head, and this elastic equilibrium mechanism is arranged between fixed mount and the thermal head.The present invention adds flexible balance device between thermal head and fixed mount, make and remain at same horizontal line between thermal head and the rubber-surfaced roll, and remain suitable printing distance, thus solved the printing paper walking process in the uneven problem of pressure, guarantee in the print procedure not paperboard.
Further improvement of the present invention is: described fixed mount is step-like tabular component, the top layer tread of described stairstepping fixed mount is provided with two waist holes, stop screw is fixed on described thermal head under this top layer tread by above-mentioned two waist holes, described thermal head slides along the long axis direction in above-mentioned two waist holes, and described elastic equilibrium mechanism is arranged between the riser and thermal head of this stairstepping fixed mount.The present invention keeps the activity of thermal head freely, is provided with the waist hole of certain move place in the fixed position, is convenient to thermal head and adjusts the position automatically.
Of the present invention further the improvement again is: be installed with the cantilever stator on the bottom tread of described stairstepping fixed mount, the bending downwards of these cantilever stator two ends protrudes in the lower surface of described bottom tread, these cantilever stator two ends respectively are provided with a fixing hole, and it is hinged with described holder and fixed mount that fixed bar passes above-mentioned two fixing holes; Be provided with first back-moving spring between described holder and the fixed mount bottom tread, described cantilever stator is arranged between first back-moving spring and the fixed mount riser.The present invention adopts cantilever design to add the mode of back-moving spring, and the vertical range of adjustment thermal head and rubber-surfaced roll makes moderate pressure between the two, and can keep constant compression force for a long time, solves paperboard and prints thin out problem.
Of the present invention further the improvement is: described elastic equilibrium mechanism is the fork-shaped shell fragment, and two jaws of this fork-shaped shell fragment are against on the described thermal head, and fork-tail is fixed on the riser of described fixed mount.Described fork-shaped shell fragment is one, and the fork-tail of this fork-shaped shell fragment is fixed on the centre position of described fixed mount riser, and two jaws of this fork-shaped shell fragment are partly for being symmetrical arranged.Perhaps described fork-shaped shell fragment is at least two, and this fork-shaped shell fragment of at least two is along fixed mount riser medium line symmetric arrangement.In the technical scheme of the present invention, elastic equilibrium mechanism adopts the compression spring, for example: coil spring and spring leaf, if employing coil spring, then be necessary for plural coil spring, the balance that so just can keep-up pressure, simultaneously, the parameter that also will guarantee each spring is identical or approaching, helps the equilibrium that keep-ups pressure.Adopt the spring leaf of fork-shaped then more suitable because the application point of fork-shaped spring is than broad, and about the fork pressure ratio average, help pressure balance, for the present invention, the fork-shaped spring is a preferred version of the present invention.
Of the present invention further the improvement is: the thread root of described stop screw is provided with the round platform that protrudes from the screw rod outer round surface, and the diameter of this round platform guarantees to be held by above-mentioned waist hole.This programme be for the activity that makes thermal head more freely, avoid the phenomenon of clamping stagnation to take place.
Of the present invention further the improvement is: extend outward boss at the printing door on described fixed mount direction, two place's peaks of this boss upper surface are in same horizontal plane, described boss is two, and the peak of these two boss upper surfaces is in same horizontal plane.Adopt the scheme of boss location among the present invention, be used for the initial installment state of positioning and fixing frame, thereby guarantee parallel between thermal head and the rubber-surfaced roll, guarantee paperboard and print evenly.
The present invention adopts above-mentioned technical scheme, makes this printing equipment paper feed more smooth and easy, and when using for a long time, also can not print thin out problem.
