Problems solved by technology
[0004] Because the thermal printer needs to change the printing paper frequently when it is working, it is often necessary to separate the print head from the frame, that is, to open the cover. Therefore, the existing print head assembly and the frame are provided with an uncap mechanism to facilitate Cap opening operation, but the existing cap opening mechanism has a complex structure, resulting in high manufacturing cost of the thermal printer core, and makes the cap opening operation difficult, which is not conducive to the operation of replacing the printing paper
[0005] In addition, the current matching structure of the print head assembly and the bracket is too complicated, resulting in a large submission and a high failure rate, which needs to be improved

The invention discloses a thermal printer which comprises a printer base, a motor, a transmission gear set, a printing head assembly, a support and a rubber roller. The thermal printer is characterized in that the rubber roller is arranged on the support through a rotating shaft; the printer base is provided with a limiting groove for arranging the rotating shaft, and the end opening of the limiting groove is upward; a detachable mechanism comprises a limiting part, a wrench and a pre-tightening spring, the limiting part comprises a connecting portion and limiting portions formed at the two ends of the connecting portion, a hook part capable of blocking the end opening of the limiting groove is arranged at the front end of each limiting portion, and a connecting shaft penetrates through the limiting portions to enable the limiting part to be arranged on the printer base; the wrench can be arranged on the printer base in a rotating mode, one end of the wrench is provided with an exposed wrench portion, the other end of the wrench stretches into the printer base to form a driving portion, the driving portion abuts against the connecting portion and can drive the connecting portion to move, and therefore the limiting portions can be driven to overturn. Compared with the prior art, the thermal printer has the advantages of being compact in overall structure, convenient to operate and capable of effectively reducing the failure rate.
Description
technical field [0001] The invention relates to a heat-sensitive printer, which can be applied to ticket printing. Background technique [0002] Most of the bank's ATMs and supermarket cash registers are equipped with thermal printers for printing transaction receipts or receipts. Thermal printers usually have a casing, and a movement is installed in the casing. The movement is composed of a print head assembly, a frame and a paper cutter, wherein the print head assembly is installed above the frame, and the paper cutter Installed on one side of the frame and print head assembly. A paper-feeding path is formed between the print head assembly and the base, and the thermal printing paper passes through the paper-feeding path. [0003] A rubber roller is installed on the upper end of the machine base of the thermal printer core, and a motor is arranged in the machine base, and the motor drives the rubber roller to rotate through a transmission mechanism, such as a gear. The ...
