Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a movement and a label printer. Background Art

[0002] With the rapid development of modern commerce and industry, label printers are increasingly used. Traditional label printing methods have problems such as low efficiency, high cost and poor printing quality.

[0003] In order to solve these problems, label printer technology came into being. Through the principle of thermal transfer or thermal printing, the ink or toner is transferred to the label paper by heating the print head, thereby achieving fast and high-quality label printing; however, during long-term use of traditional label printers, due to the unreasonable design of the internal structure of the printer, it is difficult to detect the misalignment of the thermal roll paper during movement, which makes the moving path of the thermal roll paper change, resulting in frequent printing blur, misalignment and unclear printing, which not only affects work efficiency, but also increases maintenance costs.

[0036] Please refer to Figure 1-5 As shown, this embodiment provides a movement 100, which includes: a paper bin 110, a rubber roller 118, a photosensitive sensor 114, a flip cover assembly 112 and a thermal print head 113; wherein the paper bin 110 has a paper outlet 11a, and the paper bin 110 is used to load a thermal paper roll 111; the rubber roller 118 is used to drive the thermal paper roll 111 to move out of the paper bin 110, that is, the thermal paper roll 111 is installed in the paper bin 110 and can be rolled through a part connected to the rubber roller 118 to move out through the paper outlet 11a; the flip cover assembly 112 can be pivotally connected to the paper bin 110 so as to cover or open the paper bin 110, the thermal print head 113 is used to print on the thermal paper roll 111, and the photosensitive sensor 114 can be used to cover or open the paper bin 110, the thermal print head 113 is used to print on the thermal paper roll 111, and the photosensitive sensor 114 can be used to cover or open the paper bin 110, and the thermal print head 113 can be used to print on the thermal paper roll 111. 114 is installed on the moving path of the thermal paper roll 111 from the paper outlet 11a to the thermal print head 113 to position the thermal paper roll 111 moving to the bottom of the thermal print head 113; further, the movement 100 also includes a control mainboard 115 and a drive motor 116, the control mainboard 115 is used to receive the sensing signal of the photo sensor 114, and the drive motor 116 is electrically connected to the control mainboard 115, so that the drive motor 116 can be controlled by the control mainboard 115 and drive the thermal paper roll 111 to roll; wherein, the photo sensor 114 can position the thermal paper roll 111 to be printed when the flip cover assembly 112 is closed on the paper bin 110.

[0037] According to the above scheme, it can be understood that this embodiment installs the photosensitive sensor 114 on the moving path of the thermal paper roll 111 from the paper outlet 11a to the thermal print head 113 to locate the position of the thermal paper roll 111 when it moves under the thermal print head 113, so that the thermal paper roll 111 can be accurately positioned in any time period of the movement of the thermal paper roll 111, thereby avoiding the problem of unreasonable internal structure design of the movement 100 of the traditional printer, which makes it difficult to detect the misalignment of the thermal paper roll 111 during the movement, and ensuring that the moving path of the thermal paper roll 111 can be timely monitored by the photosensitive sensor 114 when it moves, thereby reducing the probability of misalignment, blur and unclear printing of the thermal paper roll 111 by the thermal print head 113, improving the working efficiency of the printer, and reducing the maintenance cost of the movement 100.

[0038] Preferably, in some embodiments, the paper bin 110 is provided with a support frame 117 extending from the front end of the paper outlet 11a, and the photo sensor 114 is installed on the flip cover assembly 112 or the support frame 117. The purpose of designing this structure is to make the setting and installation structure of the photo sensor 114 more flexible, thereby improving the structural compactness of the movement 100.

[0039] Preferably, in other embodiments, the paper bin 110 is provided with a support frame 117 extending from the front end of the paper outlet 11a. Optionally, in this embodiment, the support frame 117 is integrally formed with the paper bin 110, and two photo sensors 114 are provided, and the two photo sensors 114 are respectively installed on the flip cover assembly 112 and the support frame 117. By designing two photo sensors 114, double-sided positioning of the thermal paper roll 111 is realized, and secondary positioning of the thermal paper roll 111 is realized, so as to avoid the positioning error of a single photo sensor 114 causing the movement of the thermal paper roll 111 to still have the problem of misalignment, and further improve the positioning accuracy of the photo sensor 114 for the thermal paper roll 111; further, in this embodiment, the installation positions of the two photo sensors 114 are relatively set, which can better capture the details and color changes of the thermal paper roll 111, and can transmit its changes to the control mainboard 115, so as to provide more accurate color and detail restoration during the printing process. This setting helps to improve the accuracy and efficiency of printing, and ensure that the printed image is closer to the original image. In addition, this setting helps to reduce color deviation and errors in the printing process, thereby improving print quality.

[0040] Preferably, the light outlet of the photoreceptor 114 is arranged relative to the center of the moving path of the thermal paper roll 111. In order to achieve high-quality printing effects, it is important to ensure the accuracy and efficiency of printing. By arranging the light outlet of the photoreceptor 114 relative to the center of the moving path of the thermal paper roll 111, the printing process can be effectively monitored and adjusted to ensure that the printed lines or characters are located at the predetermined position to avoid offset or misalignment. This setting method helps to improve the printing quality and make the printed image clearer and more accurate.

[0041] In addition, this setting also helps to increase the printing speed. Because when the photosensitive sensor 114 can accurately capture every point on the thermal paper roll 111, the printer can proceed to the next step more quickly, thereby improving the overall printing efficiency. This is particularly important for application scenarios that require fast and large-scale printing, such as commercial receipt printing, label printing, etc., which can significantly improve work efficiency.

[0042] Preferably, the movement 100 includes a rubber roller 118 for driving the thermal paper roll 111 to move out of the paper bin 110. The rubber roller 118 is installed on the support frame 117 and is located on one side of the photosensitive sensor 114. The rubber roller 118 is electrically connected to the drive motor 116 so as to be driven by the drive motor 116 to rotate and drive the thermal paper roll 111 to move outward from the paper bin 110; further, a rotating bin 12a is provided on the support frame 117, and the rubber roller 118 is installed in the rotating bin 12a and can rotate in the rotating bin 12a; the thermal print head 113 is crimped to one side of the rubber roller 118 when the flip cover assembly 112 is snap-fitted to the paper bin 110, thereby causing the thermal paper roll 111 driven by the rubber roller 118 to pass between the rubber roller 118 and the thermal print head 113 and be applied with an extrusion force, thereby maintaining the stability of the tension of the movement of the thermal paper roll 111.

[0043] Preferably, the movement 100 also includes a return spring 121 installed in the flip cover assembly 112, one end of the return spring 121 abuts against the inner wall of the flip cover assembly 112, and the other end abuts against the back of the thermal print head 113. It can be understood that the purpose of providing the return spring 121 is to enable the thermal print head 113 to generate an elastic force when the rubber roller 118 abuts against each other, so that the abutment force of the thermal print head 113 on the rubber roller 118 can be changed by the return spring 121. The advantage of this structure is that the elastic action of the return spring 121 can be used to adapt to thermal roll paper 111 of different thicknesses, thereby improving the practicality of the printer movement 100.

[0044] The present embodiment also provides a label printer 200, including a movement 100 as any one of the above items, and further, the label printer 200 also includes a shell 211, and the movement 100 is installed in the shell 211; further, the label printer 200 also includes a control button 212, and the control case is installed in the shell 211 and is electrically connected to the control motherboard 115 to control the operation of the thermal print head 113 and the drive motor 116.

[0045] In summary, the utility model provides a movement and a label printer, which installs a photo sensor on the moving path of the thermal paper roll from the paper outlet to the thermal print head to locate the position of the thermal paper roll when it moves to under the thermal print head, so that the thermal paper roll can be accurately positioned in any time period of the movement of the thermal paper roll, thereby avoiding the problem of unreasonable internal structure design of the movement of traditional printers, which makes it difficult to detect the misalignment of the thermal paper roll during the movement, and ensures that the moving path of the thermal paper roll can be timely monitored by the photo sensor when it moves, thereby reducing the probability of misalignment, blur and unclear printing of the thermal paper roll by the thermal print head, improving the working efficiency of the movement, and reducing the maintenance cost of the movement.
