[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] like Figures 1-7As shown, a receipt printing device according to one embodiment of this utility model includes a housing 1, a paper cutting mechanism 2, and a heat dissipation mechanism 3. The housing 1 has a receipt outlet 11, and a paper storage box is provided inside the housing 1 for holding printing paper 4. The printing paper 4 is dispensed through the receipt outlet 11. The paper cutting mechanism 2 is located inside the housing 1. The heat dissipation mechanism 3 is located at the bottom of the housing 1 and includes a mounting frame 31, fan blades 32, and a drive motor 33. The fan blades 32 are located inside the mounting frame 31 and are rotatably connected to the mounting frame 31. The drive motor 33 is located inside the mounting frame 31 and connected to the fan blades 32. After printing is completed, the paper cutting mechanism 2 starts to cut the paper. At the same time, the heat dissipation mechanism 3 also starts to work, using the rotation of the fan blades 32 to dissipate heat from inside the device, ensuring stable operation of the device. By setting up a heat dissipation mechanism 3, the heat generated by the equipment during operation is dissipated in a timely manner to ensure the stable operation of the equipment. The heat dissipation mechanism 3 includes a mounting frame 31, a fan blade 32, and a drive motor 33. The mounting frame 31 provides a stable mounting environment for the fan blade 32 and the drive motor 33 to ensure that they can work normally. The drive motor 33 provides power for the rotation of the fan blade 32. When the drive motor 33 is working, the fan blade 32 will rotate accordingly, generating airflow to dissipate the heat inside the equipment through the heat dissipation holes or gaps in the casing 1.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: a support frame 311 is provided on the mounting frame 31 to provide stable support for the rotation of the fan blade 32, a connecting shaft 312 is provided on the support frame 311, the fan blade 32 is rotatably mounted on the connecting shaft 312, the connecting shaft 312 is the axis of rotation of the fan blade 32, and the fan blade 32 can rotate freely on the support frame 311.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: the fan blade 32 rotates counterclockwise from the center of the fan blade 32 away from the fan blade 32. The counterclockwise rotating fan blade 32 can generate outward airflow, which helps to dissipate heat from the inside of the casing 1, ensuring that heat does not accumulate inside the equipment, thereby reducing the risk of overheating of the equipment.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: a plurality of notches 321 are provided at the lower edge of the fan blade 32 near the center, and the notches 321 are evenly distributed at equal intervals, so that the fan blade 32 can cut the air better when rotating, forming a smoother airflow, which helps to reduce the airflow resistance on the surface of the fan blade 32 and improve the heat dissipation efficiency.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: a plurality of air grooves 322 are provided at the outer edge of the fan blade 32, and the air grooves 322 are evenly distributed at equal intervals. The width of each air groove 322 gradually decreases from bottom to top. When the airflow passes through the air grooves 322, the airflow speed increases due to the gradual reduction of the air grooves 322, which helps to reduce the airflow resistance on the surface of the fan blade 32. The optimized airflow path allows heat to be carried away more quickly, thereby improving the heat dissipation efficiency.

[0036] As a preferred embodiment of the present invention, it may also have the following additional technical features: the bottom of the housing 1 is provided with a number of heat dissipation vents 11, which work together with the heat dissipation mechanism 3 to achieve synchronous heat dissipation and increase the heat dissipation rate. Each heat dissipation vent 11 is provided with a dustproof net 12 to prevent external dust from entering the housing 1 from the heat dissipation vent 11.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the paper cutting mechanism 2 includes a pressing structure 21, a moving structure 22, and a paper cutting blade 23. The pressing structure 21 is disposed below the moving structure 22, and the paper cutting blade 23 is fixedly connected to the moving structure 22. By setting the pressing structure 21, the receipt printing paper 4 is prevented from rotating and is also prevented from being easily pulled out. By setting the moving structure 22, it is responsible for driving the paper cutting blade 23 to perform the cutting action, ensuring the straightness and accuracy of the cut. By setting the paper cutting blade 23, it is the direct tool for cutting paper, and is made of high hardness and wear-resistant material to ensure that it can still maintain a good cutting effect after long-term use.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: The pressing structure 21 includes a rotating rod 211, a first motor 212, and a pressing block 213. The rotating rod 211 is disposed below the moving structure 22. One end of the rotating rod 211 is fixedly connected to the driving end of the first motor 212, and the end of the rotating rod 211 away from the first motor 212 is rotatably connected to one side of the inside of the housing 1. The first motor 212 is fixedly connected to the housing 1, and the outer wall of the rotating rod 211 is fixedly connected to the pressing block 213. When the paper cutting mechanism 2 is used, the first motor 212 starts and drives the rotating rod 211 to rotate. As the rotating rod 211 rotates, the pressing block 213 also moves and gradually approaches the paper. When the pressing block 213 contacts the paper, it continues to apply pressure to fix the paper in the appropriate position. At this time, the moving structure 22 can start to move and drive the paper cutting blade 23 to cut. After cutting is completed, the first motor 212 reverses, causing the rotating rod 211 and the pressing block 213 to return to their initial positions, so that the user can take out the cut paper.

[0039] As a preferred embodiment of this utility model, it may also have the following additional technical features: the movable structure 22 includes a rotating roller 221, a second motor 222, a first movable plate 223, and a second movable plate 224. The rotating roller 221 is fixedly connected to the drive end of the second motor 222. The outer wall of the rotating roller 221 is provided with the first movable plate 223. The side of the first movable plate 223 away from the rotating roller 221 is fixedly connected to the second movable plate 224. The paper cutting blade 23 is fixedly connected to the side of the second movable plate 224 away from the first movable plate 223. The rotating roller 221 is elliptical in shape. A groove is provided on the side of the first movable plate 223 near the rotating roller 221, and the rotating roller 221 abuts against the groove. When the paper cutting mechanism 2 is used, the second motor 222 starts and drives the rotating roller 221 to rotate. As the rotating roller 221 rotates, it rolls along the groove on the first movable plate 223, causing the first movable plate 223 to move accordingly. This movement is transmitted to the second movable plate 224 and the paper cutting blade 23, causing them to move and cut along a preset path.

[0040] As a preferred embodiment of this utility model, it may also have the following additional technical features: the paper cutting mechanism 2 includes a limiting mechanism 24, which is fixedly connected to the housing 1. The limiting mechanism 24 includes a limiting sliding member 241, a positioning plate 242, and an elastic member 243. The limiting sliding member 241 is slidably connected to the top end of the second movable plate 224, the positioning plate 242 is fixedly connected to the limiting sliding member 241, one end of the elastic member 243 is fixedly connected to the second movable plate 224, and the end of the elastic member 243 away from the second movable plate 224 is fixedly connected to the positioning plate 242. This provides necessary constraints and support for the second movable plate 224 and the paper cutting blade 23 thereon, ensuring the stability and accuracy of the cutting process. In this embodiment, the elastic member 243 is set as a return spring, and a groove 2411 is provided on the limiting sliding member 241, within which the second movable plate 224 moves.

[0041] As a preferred embodiment of this utility model, it may also have the following additional technical features: a plurality of cutting teeth 231 are provided on one side of the paper cutting blade 23. The shape of the cutting teeth 231 can be triangular, trapezoidal, wavy, etc., and different shapes have different effects on the cutting effect. The shape and number of cutting teeth 231 can be adjusted according to the paper type to provide a better cutting effect.

[0042] The working principle of the receipt printing device in this embodiment is as follows: When the device is in use, the drive motor 33 is turned on, causing the fan blade 32 to rotate and maintain heat dissipation. After the receipt paper 4 is printed, the second motor 222 will start automatically. The second motor 222 drives the rotating roller 221 to rotate. The rotating roller 221 is set to an elliptical shape. The rotating roller 221 will touch the first movable plate 223 twice when it rotates one revolution, causing the first movable plate 223 to move twice to one side of the receipt paper 4. The cutting teeth 231 on the paper cutting blade 23 will cut the receipt paper 4, making it easier to tear off the receipt paper 4. The paper cutting blade 23 moves twice, which can not delay the printing work and make it easier to tear off the receipt paper 4. When the paper cutting mechanism 2 is running, the second movable plate 224 will slide within the limiting sliding member 241, and the second movable plate 224 will pull the elastic member 243. After one cut is completed, the elastic member 243 will automatically return to its original position for the next cut, making it easier for the paper cutting blade 23 to return to its original position for the next work. After the paper cutting is completed, the first motor 212 is started. The rotation of the first motor 212 drives the pressing block 213 to rotate to one side of the receipt paper 4 through the rotating rod 211, so that the pressing block 213 presses the receipt paper 4, preventing the receipt paper 4 from rotating back and preventing the receipt paper 4 from being easily pulled out. When the printing equipment is started, the first motor 212 can rotate in the opposite direction to protect the receipt paper 4 and also to ensure that tearing off the receipt paper 4 will not damage the unprinted receipt paper 4.

[0043] The receipt printing device in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other devices with similar usage requirements. In this embodiment, the receipt printing device can effectively dissipate the heat inside the casing 1, prevent the device performance from deteriorating due to long-term high-temperature operation, and thus extend the service life of the receipt printing device.
