[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a cash register receipt printing device, including a housing 1. A protective cover 2 is rotatably connected to the top of the housing 1. The protective cover 2 is used to protect the internal components and prevent dust or external objects from entering and affecting the printing effect. A limiting component is provided on the top of the housing 1 to fix the installed thermal paper and prevent the paper roll from shifting during printing, ensuring smooth printing. A limiting groove 5 is provided inside the housing 1, which provides sliding space for a slider 7, allowing the slider 7 to move within a certain range to adapt to the installation requirements of paper rolls of different sizes. An adjustment component is provided inside the housing 1 so that users can make fine adjustments according to the paper roll specifications, improving the compatibility and applicability of the device. The adjustment assembly includes a slider 7, which is slidably connected inside the limiting groove 5. The sliding of slider 7 allows the limiting block 8 to move accordingly, enabling adjustment and limiting of the thermal paper roll. The limiting block 8 is fixedly connected to the top of slider 7, and a lever 9 is fixedly connected to one side of limiting block 8. The lever 9 facilitates manual adjustment of the slider 7's position, improving the convenience of limiting adjustment. A limiting groove 10 is formed inside slider 7, providing sliding space for the limiting plate 11, ensuring that the limiting plate 11 moves within a limited range. The limiting plate 11 is slidably connected inside slider 7, and a locking block 13 is fixedly connected to one side of limiting plate 11. The locking block 13 plays a fitting and fixing role in the limiting structure, preventing slider 7 from shifting during use and affecting the limiting effect. A locking block 6 is fixedly connected inside housing 1, engaging with locking block 13 to achieve stable limiting and prevent slider 7 from loosening after adjustment, thus affecting printing stability. The slider 7 is equipped with a reset component to automatically reset after adjustment, improving ease of use and avoiding the inconvenience of frequent manual adjustments. A limit block 12 is fixedly connected to the outer wall of the first limit plate 11, and the second limit block 12 is slidably connected inside the second limit groove 10, allowing the first limit plate 11 to slide stably within the groove and ensuring the accuracy of the limit adjustment. The limit component includes a bracket 3, the bottom of which is fixedly connected to the top of the housing 1. The bracket 3 provides stable structural support, preventing the limit component from shaking during use and improving the overall stability of the equipment. A limit shaft 4 is fixedly connected to one side of the bracket 3, supporting and fixing the adjustment mechanism to ensure the adjustment component remains stable during adjustment. The reset component includes a telescopic rod 14, the outer wall of which is fitted with a first spring 15. The first spring 15 provides a rebound force, allowing the adjusted limit component to quickly reset, preventing printing effects caused by failure to return to its original position after adjustment. The telescopic rod 14 and the first spring 15 are both fixedly connected between the limiting plate 11 to ensure the stability of the reset assembly and improve the durability and service life of the limiting assembly.

[0020] Reference Figure 4The housing 1 has an internal mounting groove 16 for accommodating the thermal paper roll, ensuring its stability during printing and allowing it to unroll smoothly, thus improving print quality. The housing 1 also has a limiting groove 17 providing sliding space for a limiting plate 18. This allows the limiting plate 18 to be adjusted according to the size of the thermal paper roll, preventing it from shifting or loosening during printing and improving equipment stability. The limiting plate 18 is slidably connected to the limiting groove 17, allowing it to move smoothly within a defined track, ensuring precise positioning and preventing paper roll misalignment or jamming due to loose limiting components. A locking pin 19 is fixedly connected to one side of the limiting plate 18. The locking pin 19 is slidably connected inside the housing 1. The locking pin 19 is used to insert into the hole in the center of the thermal paper roll to fix it, ensuring axial stability of the paper roll during use and preventing uneven printing or abnormal paper feeding due to rolling or shaking, thus improving the stability of print quality. A telescopic rod 20 is provided inside the housing 1.

A second spring 21 is sleeved on the outer wall of the telescopic rod 20. The second spring 21 provides a rebound force to the limiting plate 18, allowing the limiting component to automatically reset when released, improving the convenience of operation and avoiding misalignment problems caused by improper installation or adjustment. One end of the telescopic rod 20 and the second spring 21 are both fixedly connected to the other side of the limiting plate 18, ensuring the stable support of the telescopic rod 20 and enabling the limiting plate 18 to return to its original position smoothly, thus improving the durability and long-term performance of the limiting assembly. The other ends of the telescopic rod 20 and the second spring 21 are both fixedly connected inside the housing 1, making the entire limiting mechanism more stable, effectively improving the stability of the printing equipment, and reducing possible shaking or displacement during printing.

[0021] Working principle: When using this cash register receipt printing device, firstly, when adjusting the spacing of the first limit block 8, manually move the lever 9. The lever 9 drives the slider 7 at the bottom of the first limit block 8 to slide in the first limit groove 5. Then, the second locking block 13 inside the slider 7 engages with the first locking block 6 for positioning, preventing the first limit block 8 from sliding arbitrarily. The second locking block 13 slides in the slider 7 through the first limiting plate 11. The first limiting plate 11 slides and is limited in the second limit groove 10 through the second limiting block 12. Supported by the tension of the first spring 15, the second locking block 13 can be stably engaged with the first locking block 6. At the same time, the limiting shaft 4 can prevent the thermal paper from separating from the first limit block 8, thus achieving the effect of limiting the thermal paper. When installing the paper roll, the thermal paper roll is placed directly into the mounting slot 16. Then, the locking pin 19 in the mounting slot 16 is inserted into the hole in the center of the paper roll to limit its position. The locking pin 19 is limited in the limiting slot 17 on the housing 1 by the limiting plate 2 18 to prevent the locking pin 19 from separating from the housing 1. Then, supported by the tension of the second spring 21, the locking pin 19 can retract into the housing 1 and reset, and stably fit into the inside of the paper roll, thus achieving the effect of limiting the paper roll.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
