[0002] One of the application areas of thermal printers is label printing, and a type of label paper with a backing paper has been developed on the market. However, traditional thermal printers cannot meet the new market demands because they do not take into account the need to peel off the backing paper at the same time when printing labels. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a thermal label peeling structure and a thermal printer that can automatically peel off the backing paper while printing the label, thus meeting the user's need for immediate label application.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides a peeling structure for the backing paper of a thermal tape, including a thermal printer body, a peeling plate, a first elastic element, and a peeling roller and a rubber roller rotatably disposed on the thermal printer body; the rubber roller is driven to rotate to move the thermal tape in the paper feeding direction; the peeling plate is disposed between the rubber roller and the peeling roller; the first elastic element applies elastic force to the peeling roller so that the peeling roller elastically abuts against the rubber roller and the peeling plate respectively, and the backing paper of the thermal tape is sequentially clamped between the peeling roller and the peeling plate and between the peeling roller and the rubber roller, thereby forming a peeling structure for the backing paper.

[0006] Furthermore, the first elastic element is a torsion spring; the peeling plate is assembled on the thermal printer body, and the torsion spring is disposed between the thermal printer body and the peeling roller.

[0007] Furthermore, the peeling plate has a paper guide portion and a bending portion connected together; the paper guide portion corresponds to the print head of the thermal printer body to support the thermal tape; the peeling roller abuts against the bending portion under the elastic constraint of the first elastic member, and the bending portion is used to guide the bottom paper to the peeling roller.

[0008] Furthermore, the print head and the rubber roller are arranged vertically, and the rubber roller is used to cooperate with the print head to heat and print the thermal strip passing between the print head and the rubber roller.

[0009] Furthermore, the thermal printer body is provided with a rotatable wrench, the wrench having a hook for detachably engaging with the print head, and a second elastic element is provided between the wrench and the thermal printer body.

[0010] Furthermore, the thermal printer body has a friction surface on the side wall facing the wrench, and the wrench has a sliding contact portion for sliding against the friction surface.

[0011] Furthermore, the second elastic element is a torsion spring; the wrench is sleeved on the end of the peeling roller via a cam structure, so that the wrench, the peeling roller, the first elastic element, and the second elastic element are linked together.

[0012] This utility model provides a thermal printer, which includes at least the above-mentioned thermal tape peeling structure.

[0013] The technical solution provided by this utility model has the following beneficial effects:

[0014] The rubber roller is driven to rotate, moving the thermal tape in the paper feeding direction and heating and printing the label paper on the thermal tape. Then, the first elastic element applies elastic force to the peeling roller, so that the peeling roller elastically abuts against the rubber roller and the peeling plate respectively. This allows the rubber roller to drive the peeling roller to rotate. When the backing paper of the thermal tape passes through the gaps between the peeling roller and the peeling plate and between the peeling roller and the rubber roller in sequence, the backing paper forms an elastic clamping setting and automatically peels off the label paper as it rotates with the peeling roller, thus meeting the user's need for immediate printing and labeling.

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] Reference Figures 1 to 6 As shown, Embodiment 1 provides a peeling structure for the backing paper of a thermal tape (hereinafter referred to as the peeling structure) so that the thermal printer can simultaneously peel off the backing paper 62 when printing the label paper 61 of the thermal tape 6.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the peeling structure of this embodiment includes a thermal printer body 7, a peeling plate 10, a first elastic member 5, and a peeling roller 4 and a rubber roller 3 rotatably disposed on the thermal printer body 7. The peeling plate 10 is disposed between the rubber roller 3 and the peeling roller 4 and assembled on the thermal printer body 7.

[0026] The thermal printer body 7 includes a printhead 2, and the printhead 2 and the rubber roller 3 are arranged in an upper and lower position. The rubber roller 3 is used to cooperate with the printhead 2. When the rubber roller 3 is driven to rotate by the drive gear assembly 72 of the thermal printer body 7, it can drive the thermal belt 6 to move in the paper feeding direction and heat and print the label paper 61 that passes through the thermal belt 6 between the printhead 2 and the rubber roller 3.

[0027] The first elastic element 5 applies elastic force to the peeling roller 4 so that the peeling roller 4 elastically abuts against the rubber roller 3 and the peeling plate 10 respectively, thus ensuring that the peeling roller 4 can be elastically pressed on the rubber roller 3. The bottom paper 62 of the heat-sensitive tape 6 is sequentially clamped between the peeling roller 4 and the peeling plate 10 and between the peeling roller 4 and the rubber roller 3, thereby forming a peeling setting on the bottom paper 62, and thus realizing the linkage peeling between the bottom paper 62 and the rubber roller 3.

[0028] In this embodiment, the first elastic element 5 is a torsion spring, and it is disposed between the thermal printer body 7 and the peeling roller 4. Of course, in other embodiments, the first elastic element can also be a tension spring or a sheet spring, or other elastic elements.

[0029] More specifically, such as Figure 3 As shown, the peeling plate 10 has a paper guide portion 101 and a bending portion 102 connected to each other, and is arranged in an L-shape.

[0030] The paper guide section 101 corresponds to the print head 2 to support the thermal tape 6 and to guide the thermally printed label paper 61 out of the paper outlet of the thermal printer body 7.

[0031] When the label paper 61 is thermally printed, the peeling roller 4 abuts against the lower part of the bending part 102 under the elastic constraint of the first elastic element 5. Through the cooperation of the bending part 102, the bottom paper 62 is guided from the paper output direction of the paper guide part 101 to the bottom paper peeling direction of the peeling roller 4. The bottom paper 62 of the thermal tape 6 passes through the gap between the peeling roller 4 and the peeling plate 10 and between the peeling roller 4 and the glue roller 3 in sequence, forming a corresponding clamping force. At the same time, the bottom paper 62 is driven in the peeling direction by the clamping force, so as to automatically peel the bottom paper 62 from the thermally printed label paper 61. That is, selective peeling of the bottom paper 62 during the printing of the thermal tape 6 can be achieved without considering the different thickness, material or hardness of the label paper 61.

[0032] The rubber roller 3 is driven to rotate, which moves the thermal belt 6 in the paper feeding direction and heats and prints the label paper 61 on the thermal belt 6. Then, the first elastic element 5 applies elastic force to the peeling roller 4 so that the peeling roller 4 elastically abuts against the rubber roller 3 and the peeling plate 10 respectively. At the same time, the friction between the rubber roller 3, the backing paper 62 and the peeling roller 4 makes the rubber roller 3 drive the peeling roller 4 to rotate. When the backing paper 62 of the thermal belt 6 passes through the gap between the peeling roller 4 and the peeling plate 10 and between the peeling roller 4 and the rubber roller 3 in sequence, the backing paper 62 forms an elastic clamping setting and automatically peels off the backing paper 62 from the label paper 61 as it rotates with the peeling roller 4, so as to meet the user's need for printing and pasting immediately.

[0033] In another preferred embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the thermal printer body 7 is provided with a rotatable wrench 1. The wrench 1 has a hook 11 for separable locking to the print head 2. A second elastic element 8 is provided between the wrench 1 and the thermal printer body 7. Specifically, the second elastic element 8 is a torsion spring. The wrench 1 is sleeved on the end of the peeling roller 4 through the cam structure 9 so that the wrench 1, the peeling roller 4, the first elastic element 5 and the second elastic element 8 are linked together, that is, the wrench 1, the peeling roller 4 and the second elastic element 8 are in a linked state.

[0034] In this specific embodiment, the thermal printer body 7 has a friction surface 71 on its side wall facing the wrench 1. The wrench 1 has a sliding contact portion 12 for sliding against the friction surface 71. Through the cooperation between the sliding contact portion 12 and the friction surface 71, the rotation angle of the wrench 1 is ensured to be within a preset range. At the same time, the cam structure 9 restricts the rotation, thereby ensuring that the wrench 1 can rotate within a preset range. Figure 6 The opening position, paper loading position, and as shown are described. Figure 1 Switch between the shown paper peeling positions.

[0035] like Figure 6 As shown, when it is necessary to open the cover, first forcefully turn the wrench 1 to the open position so that the hook 11 of the wrench 1 releases the locking restriction on the print head 2, so that the print head 2 can be taken out. After that, it is convenient to replace the new thermal tape 6 roll or clean the inside of the thermal printer body 7.

[0036] like Figure 6 As shown, after opening the cover and when paper needs to be loaded, forcefully turn the wrench 1 to the paper loading position. With the cooperation of the cam structure 9, the wrench 1 drives the peeling roller 4 to move away from the rubber roller 3 and the peeling plate 10, thereby increasing the gap width between the peeling roller 4 and the peeling plate 10 and between the peeling roller 4 and the rubber roller 3. At this time, after loading the thermal tape 6 roll onto the feed roll of the thermal printer body 7, the user can pre-tear the bottom paper 62 of the thermal tape 6 away from the feed roll, and pass the pre-torn bottom paper 62 through the gap between the peeling roller 4 and the peeling plate 10 and between the peeling roller 4 and the rubber roller 3 to complete the paper loading action.

[0037] After the paper loading process is completed, release the lever 1, and under the elastic force of the first elastic element 5 and the second elastic element 8, the lever 1 will automatically rotate back to the starting position. Figure 1 At the bottom paper peeling position shown, the hook 11 re-locks the print head 2, and the peeling roller 4 elastically abuts against the glue roller 3 and the peeling plate 10 respectively under the elastic force restriction of the first elastic member 5 and the second elastic member 8, so as to ensure that the label paper 61 is automatically peeled off from the bottom paper 62 while it is being thermally printed.

[0038] By changing the stroke of wrench 1, the state switching between the cover opening position, the paper loading position and the bottom paper peeling position can be completed, and the peeling structure of this embodiment can be prevented from failing while the cover is being opened.

[0039] Moreover, switching between different wrench states not only facilitates internal cleaning and inspection of the thermal printer body 7, but also eliminates the need for repeated paper loading.

[0040] Furthermore, the peeling structure of this embodiment can print thermal tape 6 on different paper media, and the overall structure is compact, allowing for quick replacement and printing of label paper 61.
