Description

Technical Field

[0001] This utility model relates to a label printing device, and more particularly to a handheld labeling machine that can be used to affix labels to product packaging or the product itself. Background Technology

[0002] Various types of labels are needed in many settings, such as offices, factories, warehouses, and shopping malls, including clothing tags, train tickets, boarding passes, luggage tags, and product labels in stores. These labels are usually small and unsuitable for ordinary printers. To address this, many printer manufacturers have developed label printers and smart label printers. However, existing label printers are relatively large and inconvenient to use by hand due to their less compact internal structure and less rational layout. Furthermore, they cannot simultaneously print and apply labels.

[0003] To address this, existing technologies disclose improved label printers. Referring to Chinese utility model patent No. ZL CN202223104684.9, "A Portable Label Printer" (authorization announcement No. CN218986132U), this patent provides a label printer that is easy to carry in a compact size. After the label paper is printed, it is output from the paper outlet. A paper cutter is needed to tear off the printed label for use, and finally, the user manually pastes it to the designated place. The label paper output and pasting operations are separate and cannot be completed continuously, which affects work efficiency. Utility Model Content

[0047] The base frame 26 has a paper inlet 2a at the rear end and a paper outlet 2b at the front end. The base frame 26 has a guide plate 261 inside that can guide the label paper 10 from the paper inlet 2a to the paper outlet 2b. In this embodiment, the base frame 26 is provided with a top cover 262 and a side cover 263 on the top and sides.

[0048] The rubber roller 29 is rotatably mounted on the base frame 26 and has an input gear 24 at its end; the thermal print head 27 is mounted on the base frame 26 and close to the rubber roller 29, and the label paper 10 passes between the thermal print head 27 and the rubber roller 29;

[0049] The first motor 25 is located inside the base frame 26, and the power output end is provided with a drive gear 251;

[0050] The first transmission assembly 20 is located within the base frame 26, with its power input end connected to the first motor 25 and its power output end connected to the rubber roller 29. Specifically, in this embodiment, the first transmission assembly 20 is a gear set, including gears 21, 22, and 23 that mesh with each other. Gears 21, 22, and 23 are all double gears. Gear 21 meshes with the driving gear 251, and gear 23 meshes with the input gear 24.

[0051] A thermal printhead 27 is disposed on the lower end face of a support plate 271. An elastic element 28 is provided on the back of the support plate 271, which always forces the support plate 271 to maintain a tendency to move towards the rubber roller 29. In this embodiment, the elastic element 28 is a torsion spring.

[0052] like Figures 6-8 As shown, in this embodiment, the housing 1 is provided with a bracket 38 and a guide plate 39 located below the bracket 38. The output roller 34 and the drive mechanism 30 are disposed on the bracket 38.

The drive mechanism 3 and the output roller 34 are both disposed on the bracket 38.

[0053] The output roller 34 is rotatably mounted on the bracket 38 near the second outlet 1d; the drive mechanism 3 is located in the inner cavity of the housing 1 and its power output end is connected to the output roller 34; in this embodiment, the drive mechanism 3 includes a second motor 35 and a second transmission component 30, the power input end of which is connected to the second motor 35 and the power output end is connected to the output roller 34.

[0054] In this embodiment, the second transmission component 30 is also a gear set, including gears 31, 32 and 33 that mesh with each other. Gears 31, 32 and 33 are all double gears. Gear 31 meshes with the drive gear 351 of the second motor 35, and gear 33 meshes with the input gear 341 of the output roller 34.

[0055] Working principle: Combining Figures 10-12 As shown, when using the device, hold the handle and press the trigger to activate the start button. The printing and drive mechanisms then operate. After the label paper 10 is printed, it enters the separator. During the output roller's pull, as the label paper passes through the separator, friction between the bent part of the separator and the label paper causes the label to separate from the backing paper. The separated label paper is then adhered to the product surface. An auxiliary wheel ensures the label is evenly adhered. After printing one set of content, release the trigger, disconnect the power, and printing ends. The entire process can be completed with one hand, with seamless printing and pasting, making it fast and convenient.

[0056] Example 2, combined with Figure 13 and Figure 14 As shown, in this embodiment, a support shaft 6 is provided at the corner of the bending portion 51. A spring 61 is sleeved on the support shaft 6 to press the backing paper 102 to increase friction. The spring 61 helps to increase friction and facilitates the rapid separation of the label and the backing paper. Other structures and working principles are the same as in Embodiment 1.
