[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, this is a schematic diagram of the label printer in this embodiment. The printer includes a housing 1, a baffle 2, a printer body 3, and an output port 4. The baffle 2 is installed at the side opening of the housing 1. The output port 4 is installed on the housing 1. Sliders are symmetrically installed at the bottom of the output port 4. The housing 1 has a sliding groove that cooperates with the slider to slide. The sliding groove has an open end and a closed end. The printer body 3 is installed inside the housing 1.

[0028] In use, the paper roll is installed inside the outer casing 1, and then the paper is pulled out and introduced into the printer body 3. The required information is printed on the paper through the printer body 3. The printed label is then discharged directly from the output port 4, making it easy for the operator to pick up and use the label. When it is necessary to clean the internal parts of the printer body 3, the cover plate 2 is opened, and the output port 4 is pulled out from one end of the slide opening, making it convenient for the operator to use cotton swabs to clean the internal parts of the printer body 3, reducing the difficulty of cleaning the internal parts of the printer body 3.

[0029] In this embodiment, a sleeve mechanism 5 is installed inside the outer shell 1. The sleeve mechanism 5 adjusts its size according to the specifications of the paper tube. A calibration mechanism is installed on the inner wall of the outer shell 1. The calibration mechanism consists of a paper calibration ring 6, a mating rod 7, and a conveying component 8.

[0030] As attached Figure 4 and Figure 5 As shown, this is a schematic diagram of the sleeve mechanism 5 in this embodiment. The sleeve mechanism 5 includes an inner sleeve 51, a middle sleeve 52, and an outer sleeve 53. The inner sleeve 51 is installed on the inner wall of the outer shell 1. The middle sleeve 52 is provided outside the inner sleeve 51, and the outer sleeve 53 is provided outside the middle sleeve 52. The inner sleeve 51, the middle sleeve 52, and the outer sleeve 53 are all symmetrically equipped with mating plates 54. The middle sleeve 52 and the outer sleeve 53 are provided with sliding grooves. The mating plates 54 are slidably connected to the sliding grooves. The middle sleeve 52 is symmetrically equipped with first locking blocks 55. The inner sleeve 51 is symmetrically equipped with grooves. The first locking blocks 55 are engaged with the grooves. The outer sleeve 53 is symmetrically equipped with second locking blocks 56 on the inner wall. The middle sleeve 52 is symmetrically equipped with mating grooves on the outer wall. The second locking blocks 56 are engaged with the mating grooves.

[0031] The inner sleeve 51, middle sleeve 52, and outer sleeve 53 are assembled according to the specifications and size of the selected printing paper tube. When a larger paper tube is selected, the middle sleeve 52 is placed outside the inner sleeve 51. At this time, the mating plate 54 outside the inner sleeve 51 slides into the sliding groove inside the middle sleeve 52 to determine the angle of the middle sleeve 52, so that the first locking block 55 is stably locked into the groove, realizing the docking of the middle sleeve 52 and the inner sleeve 51. Then, the outer sleeve 53 is placed outside the middle sleeve 52. At this time, the mating plate 54 outside the middle sleeve 52 slides into the sliding groove in the outer sleeve 53, and the second locking block 56 is locked into the docking groove to lock the position of the outer sleeve 53. Finally, the paper tube is installed outside the outer sleeve 53. The mating plate 54 outside the outer sleeve 53 can also lock the position of the paper tube to prevent the paper tube from spinning freely on the outer surface of the outer sleeve 53.

[0032] As attached Figure 6 and Figure 7 As shown, a mating rod 7 is installed on the inner wall of the outer casing 1, and a paper calibration ring 6 is provided on the outside of the mating rod 7. The paper calibration ring 6 is a hollow ring structure, and an anti-slip rubber layer is installed on the inner wall of the paper calibration ring 6. A conveying component 8 is installed on the side of the printer body 3. The conveying component 8 includes a conveying column 81, an elastic retaining ring 82, and a pressing block 83. The conveying column 81 is installed on the side of the printer body 3, and the elastic retaining ring 82 is slidably installed on the outside of the conveying column 81. The pressing block 83 is symmetrically installed on the inner wall of the elastic retaining ring 82, and the pressing block 83 is in contact with the outer wall of the conveying column 81.

[0033] The printing paper is pulled out of the paper tube and then attached to the outside of the mating rod 7 and introduced into the outer surface of the conveying column 81, so that the printing paper enters the printer body 3 stably, which facilitates the subsequent operation and use of the printer. The mating rod 7 and the elastic retaining ring 82 are used to adjust the position of the paper calibration ring 6 and the elastic retaining ring 82 according to the width of the printing paper itself, so that the paper calibration ring 6 and the elastic retaining ring 82 block and limit the edge of the printing paper. The anti-slip rubber layer and the squeezing block 83 in the paper calibration ring 6 lock the position of the paper calibration ring 6 and the elastic retaining ring 82, ensuring that the paper calibration ring 6 and the elastic retaining ring 82 will not slide outside the mating rod 7 and the conveying column 81 unless the operator pushes them.

[0034] As attached Figure 6 As shown, a waste take-up roller is installed on the inner wall of the outer casing 1. The printing paper set outside the sleeve mechanism 5 passes through the mating rod 7 and the conveying column 81 and enters the printer body 3. Then it is introduced into the waste take-up roller. In use, the waste take-up roller is used to collect the printed paper, and the label on the printed paper is directly discharged through the output port 4.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
