Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a handheld label printer provided with a paper bin replacement structure. Background Art

[0002] In today's fast-paced business environment, handheld label printers have become an indispensable tool for many industries. However, existing handheld label printers have some significant problems in paper bin handling.

[0003] Traditional handheld label printers with a single paper hopper have significant limitations. When the hopper runs out of paper, manually replacing it is not only time-consuming and labor-intensive, but can also easily interrupt the printing process. This can lead to issues like paper jams and wrinkles in applications where continuous and efficient label printing is essential. This irregular and uncertain operation can significantly impact the printer's performance and lifespan.

[0004] For example, a paper bin structure and handheld printing device, with publication number CN216733566U, relate to the technical field of printing equipment. The paper bin structure includes a paper bin body and a bin cover assembly mounted on the paper bin body, with a paper outlet formed between the bin cover assembly and the paper bin body. The bin cover assembly includes a bracket and a paper bin cover, the bracket including a hinged portion and a snap portion, the hinged portion being hinged to a side of the paper bin body away from the paper outlet, and the paper bin cover including a release portion and a lid-lifting portion. The provided paper bin structure can drive the release portion to abut against the snap portion by shifting the lid-lifting portion, thereby releasing the snap portion from the paper bin body and making lid opening more convenient.

[0005] When using the above-mentioned paper bin structure and handheld printing device, the manual paper changing operation is not only inefficient, but also very easy to cause untimely paper changing due to human negligence. However, there are other problems in it, such as label cutting. It is difficult to ensure the consistency of force and angle in manual operation, and the tearing edges are often uneven. The existing technical means generally have the problems of low precision and poor stability. During the manual paper tearing process, it is easy to cause the label to be torn or damaged due to excessive force, resulting in paper waste and increased costs. Utility Model Content
