[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. It should be understood that these embodiments are merely for further explanation of this utility model and should not be construed as limiting the scope of protection of this utility model. Technical engineers in the field can make some non-essential improvements and adjustments to this utility model based on the above-described content. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-6 A device for preventing motor stalling during high-speed printing includes a printing mechanism 1, a core support 2, a buffer arm 3, and a tension spring 4. The printing mechanism 1 is located inside the printer, and the core support 2 is located inside the printing mechanism 1. The core support 2 has multiple rotating shaft grooves 5. Multiple rotating shafts 8 are located on one side of the buffer arm 3, and the rotating shafts 8 are rotatably mounted in the rotating shaft grooves 5. A buckle 6 is provided on the rotating shaft groove 5 to prevent the rotating shafts 8 from falling out of the rotating shaft groove 5. Multiple first hooks 7 are provided at the bottom of the core support 2, and multiple second hooks 9 are provided on the buffer arm 3 corresponding to the rotating shafts 8. Multiple tension springs 4 are provided, and each tension spring 4 has hooks at both ends, with the two hooks connecting to the first hooks 7 and the second hooks 9 respectively.

[0021] In this embodiment, there are two of each of the following components: tension spring 4, shaft groove 5, rotating shaft 8, first hook 7, and second buckle 8.

[0022] See Figure 6 The buffer arm 3 is also designed with rounded corners 10, which can prevent paper from being scratched during paper feeding; the rounded corners 10 are set on the side away from the rotating shaft 8, and the rounded corners 10 can be continuous or intermittent.

[0023] See Figure 1 The printer has a paper roll 12 inside, with paper 13 wound around it. The printer also has a rubber roller 14 inside for moving the paper 13. The rubber roller 14 is located above the buffer rotating arm 3. During use, the paper 13 first passes through the rounded corner 10 and then passes through the bottom of the rubber roller 14, and finally comes out of the paper outlet of the printer.

[0024] In use, the buffer arm 3 is installed inside the machine frame 2, that is, the shaft 8 of the buffer arm 3 is inserted into the shaft groove 5 of the machine frame 2. The buckle 6 in the shaft groove 5 locks the shaft 8 on the buffer arm 3, so that the buffer arm 3 can be disengaged. The hook at one end of the tension spring 4 is installed on the first hook 7 of the machine frame 2, and the other end is installed on the second hook 9 of the buffer arm 3. At this time, the buffer arm 3 is in a tensioned state. After the paper roll 12 is loaded, the paper 13 passes through the rounded corner 10 on the buffer arm 3. When the rubber roller 14 drives the paper 13 to move, the paper 13 is straightened, so the buffer arm 3 will rotate downward around the shaft 8, which increases the paper feeding buffer, reduces the motor load, and prevents the motor from stalling when printing at high speed.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
