[0025] The exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] The present invention provides a label box with a sticker positioning function. As a consumable of a label printer, the label box has a sticker positioning function and at the same time has the characteristic of being unlockable.

[0027] Reference Figure 1-2As shown, a label box with a sticker positioning function includes a housing 2, and a sticker roll 1 is placed inside the housing 2. In this embodiment, the housing form is a combination of an upper housing and a lower housing, where the housing 2 is the lower housing in this embodiment. Of course, this method is for convenient assembly. In fact, it is not limited to the above-mentioned housing form of the upper and lower housing combination. Those skilled in the art can select the housing form according to actual needs. A fixed sticker channel is provided near one side inside the housing 2, and the sticker 11 extends through this sticker channel to the paper outlet of the label box. The upper housing 4 and the housing 2 (lower housing) need to protect a certain width of the upper and lower edges of the sticker 11 inside the sticker channel to prevent the sticker 11 from slipping out of the sticker channel.

[0028] A paper pressing spring arm 3 is installed at the housing 2 outside the sticker channel; at the same time, it is coordinated with Figure 3 As shown, the paper pressing spring arm 3 includes a paper pressing arm 31 and a driving spring arm 32, and the paper pressing arm 31 and the driving spring arm 32 are connected so that the paper pressing spring arm 3 can rotate around the connection center of the two. The paper pressing spring arm 3 is rotatably connected to the housing at the connection center; at the position corresponding to the end of the driving spring arm 32 outside the sticker channel on the housing, a driving spring arm end positioning part 21 is provided; at the position corresponding to the end of the paper pressing arm 31 inside the sticker channel on the housing, a rib or a vertical wall 22 is provided; when the label box is in a normal state, the driving spring arm 32 is toggled a certain stroke, generates a certain elastic force and then is caught on the driving spring arm end positioning part 21. Under the action of the driving spring arm 32, the end of the paper pressing arm 31 can press the sticker 11 tightly on the rib or the vertical wall 22; at this time, due to the action of the pressing binding force, the label box has a two-way function of preventing the sticker from retracting and preventing the sticker from being pulled outwards, ensuring the accurate and stable position of the sticker, avoiding unnecessary sticker waste caused by the sticker being pulled out, and improving the sticker utilization rate. For the above-mentioned label box, when in use for printing, since the driving spring arm 32 has a certain elastic force, it can drive the paper pressing arm 31 to rotate around the connection center when receiving a pressure towards the inside of the housing, so that the end of the paper pressing arm 31 disengages from the rib or the vertical wall 22, releasing the binding force for pressing the sticker, and has the characteristic of being unlockable. Therefore, it does not prevent normal printing.

[0029] The above-mentioned driving spring arm end positioning part 21 is preferably a protruding structure on the housing, such as but not limited to a protruding column. The driving spring arm 32 is toggled outwards a certain stroke, generates a certain elastic force and then is caught on the protruding column of the housing (it should be noted here that Figure 1 、 2 the driving spring arms 32 in are in an uncaught state). By this method, it can be ensured that the end of the paper pressing arm 31 can generate sufficient pressing binding force.

[0030] The paper pressing spring arm 3 is rotatably connected to the housing at the connection center, preferably but not limited to the following two methods. One method is as shown in Figure 1-3As shown in the figure, protruding positioning posts 33 are provided at both the upper and lower ends of the connection center of the paper pressing arm 31 and the driving elastic arm 32. The paper pressing arm 31 and the driving elastic arm 32 can rotate around the upper and lower two positioning posts 33 as the centers. Corresponding positioning holes are provided at the corresponding positions of the housing. When the housing is formed by fitting the upper and lower housings, corresponding positioning round holes are provided at the corresponding positions of the upper and lower housings. Alternatively, in the second method, a positioning through hole is provided at the connection center of the paper pressing arm 31 and the driving elastic arm 32, and a positioning shaft is provided at the position of the housing corresponding to the positioning through hole; the paper pressing arm 31 and the driving elastic arm 32 can rotate around the positioning shaft as the center. Through the above structure, the paper pressing elastic arm 3 can rotate around the connection center. The above paper pressing elastic arm 3 is buckled between the upper housing 4 and the lower housing, and openings are provided at the housing corresponding to the middle section of the driving elastic arm 32 of the paper pressing elastic arm 3 and the paper pressing arm 31. Through the above openings, it is convenient to apply pressure to the driving elastic arm from the outside to the inside of the housing, thereby driving the rotation of the paper pressing arm 31.

[0031] The end of the paper pressing arm 31 and the vertical rib or vertical wall 22 adopt a concave-convex matching structure. For example, the end of the paper pressing arm 31 adopts a groove structure (as Figure 3 shown), and the vertical rib or vertical wall 22 adopts a convex structure matching the groove structure; or, the end of the paper pressing arm 31 adopts a convex structure, and the vertical rib or vertical wall 22 adopts a groove structure matching the convex structure. The groove and the convex cooperate with each other to press the sticker more reliably and stably, thereby realizing accurate and stable positioning of the sticker position.

[0032] fit Figure 3 As shown in the figure, the end of the driving elastic arm 32 is in a hook shape, the hook 321 faces the inside of the housing, the hook 321 catches on the protruding column of the housing, and there is an activity space between the hook 321 and the sticker in the sticker channel; the activity space between the two can make the driving elastic arm 32 move relatively with the protruding column when receiving an inward pressure, so that the middle section of the driving elastic arm 32 is slightly bent towards the inside of the housing, and then drives the end of the paper pressing arm 31 to disengage from the vertical rib or vertical wall 22.

[0033] fit Figure 3 As shown in the figure, the paper pressing arm 31 is preferably but not limited to a plate-like structure. The end of the plate-like structure is bent towards the inside of the housing, and the bent end is the pressing end, and the above-mentioned concave-convex structure is arranged at the pressing end; the above-mentioned plate-like structure can be an intermediate open plate or a non-open plate.

[0034] The width of the paper pressing arm 31 is smaller than the width of the sticker 11 in the housing and larger than the width of the driving elastic arm 32, so that the paper pressing arm 31 can perform effective pressing restraint.

[0035] In the above embodiments, the driving spring arm 32 of the paper pressing spring arm 3 is preferably made of a metal spring piece, which can generate a certain elastic deformation under the action of an external force, while the paper pressing arm 31 is preferably made of a plastic material, and the paper pressing spring arm 3 is preferably but not limited to an integrally formed structure.

[0036] Of course, the above-mentioned label box with a positioning function can be a paper roll box with only a sticker paper roll or a label box integrating a ribbon and a sticker paper roll.

[0037] In summary, the above-mentioned label box of the present invention can effectively constrain and position the label sticker, can not only prevent the sticker from retracting, but also prevent the sticker from being pulled outwards. It has a simple structure, is easy to assemble, and at the same time has the characteristic of being unlockable, and is suitable for popularization and application.

[0038] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modifications, equivalent changes or decorations made by those skilled in the art using the disclosed technical content above all fall within the protection scope of the present invention.
