Technical Field

[0001] The utility model relates to the technical field of printer accessories, in particular to an anti-static printer core and a printer. Background Art

[0002] Most bank ATMs and supermarket cash registers are equipped with thermal printers for printing transaction receipts or tickets. A thermal printer usually has a housing, in which a movement is installed. The movement consists of a print head assembly, a support, and a paper cutter. The print head assembly is installed above the support, and the paper cutter is installed on one side of the support and the print head assembly. A paper feed channel is formed between the print head assembly and the support, and the thermal printing paper passes through the paper feed channel.

[0003] Existing printers will have static electricity during the printing process, so static electricity needs to be conducted through multiple grounding wires. The use of wires for conduction greatly wastes materials and labor installation costs.

[0004] In view of this, the inventor specially designed an anti-static printing mechanism and a printer, and this case was thus generated. Utility Model Content

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figures 1 to 9 , is an anti-static printer movement as the best embodiment of the utility model, including a movement support 10, a rotating shaft 20, a thermal head bracket 221 annular inclined surface; 30, a drive motor 40, and a conductive sheet 50, the rotating shaft 20 is arranged on the movement support; the thermal head bracket 221 annular inclined surface; 30 is arranged on the rotating shaft 20, and the thermal head bracket 221 annular inclined surface; 30 can be used to install the thermal head sheet; the drive motor 40 is arranged on the movement support 10; the conductive sheet 50 is arranged on the movement support 10 and connects the rotating shaft 20 and the drive motor 40 (paper feeding motor). The conductive sheet 50 provided in the anti-static printer mechanism of the utility model is used to connect the drive motor 40 and the rotating shaft 20. Since the annular inclined surface 30 of the thermal head bracket 221 on the rotating shaft 20 can be used to install the thermal head chip, the static electricity of the thermal head chip will be transmitted to the rotating shaft 20 through the annular inclined surface 30 of the thermal head bracket 221, and then transmitted to the conductive sheet 50. Therefore, the static electricity conduction of the thermal head chip and the paper feeding drive motor 40 can be realized through the conductive sheet 50, which reduces the material waste of the grounding wire and improves the convenience of assembly.

[0040] Please refer to Figure 1 , 5 The movement support 10 is provided with a first through hole 11 for the rotation shaft 20 to pass through, and the movement support 10 is also provided with an escape position 12 for communicating with the first through hole 11. An extension portion 51 is provided on the conductive sheet 50, and the extension portion 51 extends into the escape position 12 and abuts against the outer wall of the movement support 10. The anti-static printer movement of the utility model also includes a metal fastener 60 for connecting the conductive sheet 50 and the drive motor 40. The static electricity on the drive motor 40 and the thermal head chip can be conducted to the conductive sheet 50 by connecting the metal fastener 60 with the extension portion 51, and then discharged uniformly through the conductive sheet 50.

[0041] The metal fastener 60 passes through the conductive sheet 50 and is disposed on the drive motor 40; the conductive sheet 50 is made of metal and is formed by a stamping process. The metal fastener 60 can be a bolt that passes through the conductive sheet 50 and is threadedly connected to the drive motor 40, or the metal fastener 60 directly uses a stepped metal piece, a slot is set on the drive motor 40, and the small end of the metal piece can be directly embedded in the slot.

[0042] Please refer to Figure 4 , 5 A positioning column 13 is also provided on the movement support 10, and a positioning hole 52 cooperating with the positioning column 13 is provided on the conductive sheet 50, so that the conductive sheet 50 can be better installed on the movement support 10, thereby improving the convenience of installation.

[0043] The utility model also provides a printer, which adopts the structure of anti-static printing core; the printer also includes a gear cover 70 which is arranged on the core support 10 and limits the movement of the rotating shaft 20 along the central axis direction thereof.

[0044] Please refer to Figure 7 The rotating shaft 20 includes a main body 21 and a mounting portion 22 disposed at one end of the main body 21. The outer diameter of the mounting portion 22 is smaller than the outer diameter of the main body 21. The movement support 10 is provided with a mounting hole 14 for cooperating with the mounting portion 22. The end of the main body 21 without the mounting portion 22 abuts against the gear cover 70, that is, the mounting portion 22 is located at the end of the main body 21 away from the gear cover 70. The mounting portion 22 is provided with an annular inclined surface at the end away from the main body 21 to facilitate better installation of the rotating shaft 20. Through the cooperation of the mounting portion 22 and the mounting hole 14, one end of the rotating shaft 20 is restricted. When the gear cover 70 is installed in place, the rotating shaft 20 can be prevented from moving to the other end. Therefore, through the cooperation of the mounting portion 22 and the gear cover 70, the rotating shaft 20 can be quickly and conveniently installed, and there is no need to use a C-type buckle, which reduces the cost of parts.

[0045] Please refer to 8 and 9 for details. Two first snap buckles 71 are arranged side by side at the bottom of the gear cover 70, and at least one second snap buckle 72 is arranged at the top. A first snap slot 15 cooperating with the first snap buckle 71 is arranged on the movement support 10, and a second snap slot 16 cooperating with the second snap buckle 72 is also arranged. The first snap buckle 71 cooperates with the first snap slot 15, and the second snap buckle 72 cooperates with the second snap slot 16, so that the gear cover 70 can be better and quickly installed on the side of the movement support 10. At the same time, the number of the first snap buckle 71 and the second snap buckle 72 is selected and set according to actual needs. The movement support 10 is also provided with an inclined surface for facilitating the installation of the first snap buckle 71 and the second snap buckle 72. In order to better restrict and fix the gear cover 70, a third snap buckle 73 is also arranged on the side wall of the gear cover 70, and a third snap slot 17 cooperating with the third snap buckle 73 is arranged on the movement support 10. The third snap buckle 73 cooperates with the first snap buckle 71 and the second snap buckle 72 so that the gear cover 70 can be stably installed on the movement support 10.

[0046] To summarize, the conductive sheet provided in the anti-static printer mechanism of the utility model is used to connect the drive motor and the rotating shaft. Since the thermal head bracket on the rotating shaft can be used to install the thermal head chip, the static electricity of the thermal head chip will be transmitted to the rotating shaft through the thermal head bracket, and then transmitted to the conductive sheet. Therefore, the static electricity conduction of the thermal head chip and the paper feeding drive motor can be achieved through the conductive sheet, which reduces the material waste of the grounding wire and improves the convenience of assembly.
