[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] It is understandable that, referring to Figures 1 to 5 The first embodiment of the present invention provides a printing device, comprising a frame 100, a print head assembly 200, a paper guide 300, and a peeler. The frame 100 is a part of the label printer and serves as the mounting base for the printing device. The print head assembly 200, the paper guide 300, and the peeler are all mounted on the frame 100. The print head assembly 200 is connected to the frame 100 and includes a print roller 210 located at the bottom. The print roller 210 drives the movement of the label and backing paper. The print head is located above the print roller 210 and prints patterns, text, and other content on the label.

[0035] The paper guide bracket 300 is located below the print head. A paper guide mechanism is installed on the paper guide bracket 300 to transport labels and substrate paper. Along the transport direction of the paper guide bracket 300, the paper guide bracket 300 is located upstream of the print roller 210. The labels and substrate paper are transported to the print head assembly 200 via the leading mechanism on the paper guide bracket 300 and then driven by the print roller 210. The stripper includes a stripping blade 410, a stripping roller 420, and a stripping pressure roller 430. After printing, the stripping blade 410 is used to separate the label from the backing paper. Therefore, the stripping blade 410 is positioned downstream of the printing roller 210. To guide and pull the backing paper, the stripping pressure roller 430 and the stripping roller 420 need to cooperate to clamp the backing paper. To accommodate space constraints, the stripping roller 420 is positioned upstream of the paper guide 300. After the backing paper is separated from the label, it passes under the paper guide 300 and is then clamped by the stripping pressure roller 430 and the stripping roller 420. The stripping roller 420 is connected to a power source and drives the backing paper to move. Furthermore, the backing paper is turned approximately 180 degrees by the stripping blade 410, facilitating stripping and tensioning. Considering that the backing paper needs to be clamped when printing different labels, the stripping pressure roller 430 is movably connected to the paper guide 300. By disassembling the stripping pressure roller 430, operation is facilitated and time is saved.

[0036] When the printing device is in operation, after printing a label, the label is separated from the backing paper by a peeler. The backing paper passes around the peeling blade 410, passes under the paper guide 300, and is clamped by the peeling roller 430 and the peeling roller 420, thereby transporting and collecting the backing paper. A take-up roller can be provided on the label printer to collect the backing paper. The integrated peeler in the printing device has a compact structure, which can reduce the height of the printhead assembly 200 and the height of the label output, facilitating connection to other label-using devices (such as labeling equipment). The label printer can be placed on a desktop for use, and labels can be directly fed into the labeling equipment, making layout easier.

[0037] Reference Figure 1 Paper Figure 5 In some embodiments of the first aspect of the present invention, the stripper further includes a stripping bracket 440, to which a stripping roller 430 is connected. One end of the stripping bracket 440 is rotatably connected to the paper guide bracket 300, and the other end of the stripping bracket 440 can be locked to the paper guide bracket 300. The stripping bracket 440 is used to move the stripping roller 430, allowing the stripping roller 430 to be disassembled, thereby facilitating the installation of the backing paper. To disassemble the stripping roller 430, the stripping bracket 440 is unlocked from the paper guide bracket 300, and the stripping bracket 440 can be rotated to separate the stripping roller 430 from the stripping roller 420, thereby facilitating the replacement of the backing paper.

[0038] It can be understood that in some embodiments of the first aspect of the present invention, the structure for locking the peeling bracket 440 and the paper guide bracket 300 is that a rotatable hook 310 is provided on the paper guide bracket 300, and the peeling bracket 440 is provided with a positioning pin 441 that cooperates with the hook 310. The positioning pin 441 is hooked by the hook 310 to achieve locking of the peeling bracket 440 and the paper guide bracket 300; when it is necessary to disassemble the peeling pressure wheel 430, the hook 310 is operated to make the positioning pin 441 fall out of the hook 310. The structure is simple and reliable, and the operation is convenient.

[0039] Furthermore, to maintain the position of hook 310, the upper end of hook 310 is rotatably connected to shaft 301 of paper guide 300. A torsion spring 320 is mounted on shaft 301, with its ends connected to hook 310 and paper guide 300, respectively. The torsion spring 320 restrains hook 310, ensuring it remains hooked to positioning pin 441. To disassemble peeling roller 430, hook 310 is rotated, disengaging positioning pin 441 from hook 310. This structure is simple, reliable, and easy to operate. Rotating hook 310 compresses torsion spring 320, and upon release, torsion spring 320 pushes hook 310 back to its original position, maintaining its hooked position to positioning pin 441 and enhancing operational stability.

[0040] It can be understood that, in order to facilitate operation, a handle portion 311 is provided on the hook 310, and the handle portion 311 is located on the side of the hook 310 away from the peeling bracket 440, and the handle portion 311 extends in the direction away from the paper guide bracket 300. When the peeling pressure wheel 430 needs to be disassembled, the user pushes the hook 310 to rotate through the handle portion 311, which facilitates force and improves ease of use.

[0041] In addition, the locking structure between the peeling bracket 440 and the paper guide bracket 300 can also be fixed by snaps, bolts, etc., as long as the requirements of fixation and detachability are met.

[0042] It can be understood that in other embodiments of the first aspect of the present invention, the stripper also includes a stripping bracket, which is connected to the paper guide bracket 300 through a snap, and the stripping pressure wheel 430 is connected to the stripping bracket. When it is necessary to disassemble the stripping pressure wheel 430, the entire stripping bracket is disassembled by operating the snap, so that the stripping pressure wheel 430 is separated from the stripping roller 420, which facilitates the operation of replacing the substrate paper.

[0043] Reference Figure 5 In some embodiments of the first aspect of the present invention, the stripping bracket 440 is a flat plate, and a folded edge 442 is provided on the edge of the flat plate, and a mounting plate 443 is provided on the folded edge 442. The stripping pressure wheel 430 is installed on the mounting plate 443. The stripping bracket 440 can be formed by sheet metal processing. The folded edge 442 can not only increase the structural strength and rigidity, but also provide space for the installation of the stripping pressure wheel 430.

[0044] Reference Figure 4 and Figure 5 In some embodiments of the first aspect of the present invention, the paper guide bracket 300 is provided with a swing arm plate 330, one end of the swing arm plate 330 is rotatably connected to the paper guide bracket 300, and the peeling roller 420 is connected to the other end of the swing arm plate 330. The position of the peeling roller 420 can be adjusted through the swing arm plate 330, and can adapt to substrate papers of different specifications.
