[0003] However, most of the current label printers do not have good heating function, and with the decrease of temperature, the adhesion of label paper and base paper is greatly weakened, so that the label paper will be separated due to friction or unsmooth movement in the paper path, affecting the use. CONTENT OF THE INVENTION

[0010] Further, the right upper end of the mounting bracket is provided with a transmission mechanism, and the transmission mechanism is located on the right side of the heating module.
[0011] Further, the heating module is fixedly provided with a wire on the front and back sides through screws, and the end of the wire away from the heating module is welded with a power supply circuit board.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] like Figures 1 to 4 As shown, a device for preventing label peeling at low temperatures according to the first aspect embodiment of this application includes: a lower housing 1, a heating module 8 and a detection component. An upper housing 2 is provided on the outer side of the upper end of the lower housing 1, and a mounting bracket 3 is installed on the inner side of the upper end of the lower housing 1. A paper feeding channel 7 is provided at the gap between the mounting bracket 3 and the upper housing 2 on the right side.
[0026] The lower housing 1, the upper housing 2, and the mounting frame 3 constitute the main body of the label printer. The mounting frame 3 has a paper tray 4 inside on the left side, and the label paper roll 5 is installed inside the paper tray 4. The mounting frame 3 and the paper tray 4 play a good role in installing the label paper roll 5, and facilitate the paper to be transported out through the paper feeding channel 7.
[0027] A transmission mechanism 6 is installed on the upper right side of the mounting bracket 3, and the transmission mechanism 6 is located on the right side of the heating module 8, so that the label paper roll 5 can be driven to transmit paper outward through the paper feeding channel 7 under the action of the transmission mechanism 6.
[0028] A heating module 8 is installed inside the right side of the upper housing 2, and wires 9 are fixedly installed on the front and rear sides of the heating module 8 by screws. A power supply circuit board 10 is soldered to the end of the wires 9 away from the heating module 8. The power supply circuit board 10 is located in the middle of the inner side of the upper housing 2.
[0029] The power supply circuit board 10 can supply power to the heating module 8 through the wire 9, so that the heating module 8 can heat the label paper roll 5 moving in the paper feeding channel 7, and avoid the phenomenon that the adhesion between the label paper and the backing paper will be greatly weakened due to the decrease in temperature.
[0030] Meanwhile, the heating surface at the lower end of the heating module 8 is flush with the upper end of the paper feeding channel 7, which allows the heating module 8 to maximize the heating effect on the label paper roll 5 without affecting the smooth paper feeding effect in the paper feeding channel 7, thereby further improving the overall performance.
[0031] The lower end of the lower housing 1 is equipped with a detection component located below the label roll 5. The detection component includes a main board 11 and a temperature sensor 12. The main board 11 is installed inside the lower end of the lower housing 1, and the temperature sensor 12 is soldered to the upper end of the main board 11.
[0032] The temperature sensor 12 is installed at the lower side of the paper outlet end of the label paper roll 5 under the action of the mainboard 11, so that the temperature sensor 12 can monitor the ambient temperature near the paper outlet end and in the paper path 7 in real time, and trigger the heating module 8 to work, so as to avoid the ambient temperature near the paper outlet end being too low to affect the adhesion of the label paper.
[0033] Working principle
[0034] First, install the label paper roll 5 in the inside of the paper bin 4, so that the right end of the label paper roll 5 passes through the paper path 7, and ensure that it is flat and wrinkle-free and covers the outside of the upper end of the transmission mechanism 6, then close the upper shell 2 to complete the installation of the label paper roll 5. Start the transmission mechanism 6, so that the transmission mechanism 6 drives the label paper roll 5 to transmit the paper outward through the paper path 7.
[0035] When the label paper roll 5 is working, the temperature sensor 12 monitors the ambient temperature near the paper outlet end and in the paper path 7 in real time. When the ambient temperature near the paper outlet end and in the paper path 7 exceeds the preset temperature, the temperature sensor 12 sends a signal to the mainboard 11, the mainboard 11 starts the power supply circuit board 10, the power supply circuit board 10 supplies power to the heating module 8 through the wire 9, at this time the heating module 8 can heat the label paper roll 5 moving in the paper path 7, and after the temperature sensor 12 monitors the heating temperature to the target temperature, it enters the constant temperature mode. The heating makes the adhesive of the label paper recover the adhesion, avoids peeling off from the backing paper, and can effectively avoid the label paper roll 5 from reducing the adhesion of the label paper and the backing paper due to the temperature reduction.
[0036] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictions). In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described. The embodiments not explicitly described are also considered to be within the scope of the present disclosure.
