Description
Technical Field
The invention belongs to the technical field of printers, and particularly relates to a flatness adjusting device for a thermal sensitive sheet test needle card of a thermal sensitive printer.
Background
A thermal printer is a device that prints images or characters by heating a special coating on the surface of thermal paper. The working principle is that the heating element in the thermal printing head is utilized to heat the surface of the thermal paper, so that the thermal coating of the paper is subjected to chemical reaction, and patterns or characters are left. The thermal printer has the advantages of high printing speed because of the characteristic of no need of ink or color ribbon, and can be widely applied to the fields of bill printing, label printing, receipt printing and the like.
In the working process of a thermal printer, the precision and stability of a thermal printing head directly influence the printing quality, and particularly, the performance of the printing head is important in an application scene with high precision requirements. Thermal printheads are typically composed of a plurality of heating elements that require a certain contact pressure with the surface of the thermal paper to ensure uniform and stable heating and thus print quality.
However, with the continuous development of thermal printers and the complexity of application environments, the contact precision of the conventional print head and thermal paper is often affected by factors such as flatness of the thermal paper, mounting precision of the print head, pressure distribution in the printing process, and the like, so that the problems of unstable printing quality, fuzzy or uneven printing effect, and the like are caused. Among these, the flatness problem of the print head is particularly pronounced. If the contact surface between the printing head and the thermal paper is uneven, or the condition that local pressure is too large or too small exists, the printing quality is reduced, meanwhile, the flatness of the thermal-sensitive sheet test needle card of the thermal printer needs to be adjusted, the adjusting process is complex, the installation is difficult, and the flatness adjusting and positioning precision is low. In view of this, we propose a thermal printer thermal film test pin card flatness adjustment device.

the bridge block on the left of the whole test system module is provided with a differential head (scale 0.01 mm) and a tension spring, the lower left corner of the disc is provided with a spring, the spring ejects the disc to the right in a natural state, the tension spring tightens the disc, and if the deviation of the needle card 13R shaft is found, the differential head is only required to be adjusted to be rotated to the accurate position for finding the needle card 13R shaft;
the whole debugging system is characterized in that four M8 fixing screws and four adjusting screws are used for fixing the parallel adjusting plates, the needle card 13 is arranged on the machine to verify that the left and right positions of the needle are inclined, and the adjusting screws at four angles are adjusted until the needle card 13 is parallel left and right.
The embodiments of the present application have been described above with reference to the accompanying drawings, in which the embodiments of the present application and features of the embodiments may be combined with each other without conflict, the present application is not limited to the above-described embodiments, which are merely illustrative, not restrictive, of the present application, and many forms may be made by those of ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are protected by the present application.
