Description

Technical Field

[0001] The invention relates to the field of label printers, and in particular to a label printer with a label box sticker positioning and unlocking function. Background Art

[0002] The label box used by the label printer has an anti-retraction structure in the industry to constrain the free state of the sticker paper roll, but it cannot prevent the sticker from being pulled outward, and the structure is relatively complicated. During printing, the anti-retraction constraint force cannot be released and unlocked, resulting in greater power required for printing.

[0003] It can be seen that the existing label box with sticker positioning function and its corresponding label printer still have inconveniences and defects in structure, method and use, and are in urgent need of further improvement. How to create a label printer that can effectively position and unlock stickers and reduce printing power has become a goal that the industry urgently needs to improve. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a printer for unlocking a special label box with a sticker positioning function, so that it can effectively position and unlock the sticker and reduce printing power.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A label printer with a label box sticker positioning and unlocking function, used for use with a label box with a sticker positioning function; the label box with the sticker positioning function is equipped with a paper pressing spring arm at the shell outside the sticker channel; the paper pressing spring arm includes a paper pressing arm and a driving spring arm, and the paper pressing arm and the driving spring arm are connected so that the paper pressing spring arm can rotate around the connection center of the two; in a normal state, the end of the driving spring arm is fixed to the shell, and under the action of the driving spring arm, the end of the paper pressing arm can press the sticker to a fixed position in the sticker channel; the label printer includes a machine body that can be built-in with a label box, and the sticker in the label box is pressed A print head is arranged at the machine body on the inner side of the channel; a rubber roller bracket with a rubber roller is movably installed on the side of the machine body, corresponding to the position of the print head; an unlocking pressure block is movably installed on the side of the machine body, corresponding to the driving elastic arm of the label box; the label printer also includes a machine back cover installed on the machine body; a first trigger member and a second trigger member are also arranged on the machine body or the machine back cover; the first trigger member is used to trigger the rubber roller bracket, driving the rubber roller to press the sticker inward to the print head; the second trigger member is used to trigger the unlocking pressure block to press the driving elastic arm inward, thereby driving the end of the paper pressing arm to tilt up and detach from the sticker.

[0007] As a further improvement of the present invention, the first trigger member and the second trigger member are located on the rear cover of the machine. When the rear cover of the machine is buckled with the machine body, the downward linear motion of the first trigger member and the second trigger member is converted into rotation or sliding of the rubber roller bracket and the unlocking block.

[0008] Furthermore, the first trigger member and the second trigger member are converted into rotation or sliding of the rubber roller bracket and the unlocking pressing block through rotation.

[0009] Furthermore, the first trigger component and the second trigger component are asynchronous trigger components or synchronous trigger components; when asynchronously triggered, the first trigger component is a first trigger component, and the second trigger component is a second trigger component.

[0010] Furthermore, the first trigger member and the second trigger member are two wedge-shaped structures located on the sides of the machine's rear cover and facing downward; when the machine's rear cover is pressed downward onto the machine body, the first trigger member first contacts the rubber roller bracket, driving the rubber roller to press the sticker onto the print head; the second trigger member then contacts the unlocking pressure block, triggering the unlocking pressure block to press the driving elastic arm inward, thereby driving the end of the paper pressing arm to tilt up and detach from the sticker; or, the first trigger member and the second trigger member are triggered synchronously.

[0011] Furthermore, the first trigger member is a long wedge structure, and the second trigger member is a short wedge structure, so that the first trigger member contacts the rubber roller bracket first, and the second trigger member contacts the unlocking pressing block later.

[0012] Furthermore, two sockets are provided on the top of the side of the machine body, and the first trigger member and the second trigger member are respectively inserted into the corresponding sockets for triggering.

[0013] Furthermore, the rear end of the rubber roller bracket is installed on the machine body through a vertical rotating shaft, and the rubber roller is arranged on the inner side of the front end of the rubber roller bracket; the rear end of the unlocking pressure block is also installed on the vertical rotating shaft; the rubber roller bracket and the unlocking pressure block can rotate around the vertical rotating shaft under the triggering action, and can return to their original position when the triggering action is cancelled.

[0014] Furthermore, the rear end of the rubber roller bracket is installed on the machine body through a vertical rotating shaft, and the rubber roller is arranged on the inner side of the front end of the rubber roller bracket; the rear end of the unlocking pressure block is also installed on the vertical rotating shaft; the rubber roller bracket and the unlocking pressure block can rotate around the vertical rotating shaft under the triggering action, and can return to their original position when the triggering action is cancelled.

[0015] By adopting the above technical solution, the present invention has at least the following advantages:

[0016] 1. The present invention provides a label printer with a label box sticker positioning and unlocking function, which is used for use with a label box with a sticker positioning function; the label box with sticker positioning, through the action of a paper pressing spring arm, the sticker in the label box is positioned at an accurate position before printing, which can not only prevent the sticker from shrinking, but also prevent the sticker from being pulled outward; correspondingly, a positioning and unlocking mechanism is set in the label printer, and when the label box is put into the printer, the rubber roller bracket is triggered to drive the rubber roller to press the sticker inward to the print head for positioning, thereby ensuring that the accurate position of the sticker is not changed, and on this basis, the unlocking pressure block is triggered to press the driving spring arm inward, thereby unlocking the positioning function of the sticker, releasing the pressing constraint force on the sticker, and the power required for printing is not increased, and the sticker is pressed by the print head and the rubber roller for printing, thereby ensuring the accurate printing position and avoiding unnecessary waste of stickers.

[0017] 2. The label printer of the present invention has a simple positioning and unlocking structure, good use effect, and is suitable for popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0025] The present invention provides a label printer, which is used in conjunction with a label box designed by the applicant and having a special structure and a sticker positioning function. The label printer is mainly used to unlock the sticker positioning function of the above-mentioned label box, and can ensure that the label printer has an effective sticker positioning function without affecting printing, thereby avoiding excessive power consumption of the printer.

[0026] like Figure 1 As shown, it is a label box 1 with a sticker positioning function, and a paper pressing elastic arm 12 is installed on the shell 11 outside the sticker channel; the paper pressing elastic arm 12 includes a paper pressing arm 121 and a driving elastic arm 122, and the paper pressing arm 121 and the driving elastic arm 122 are connected so that the paper pressing elastic arm 12 can rotate around the connection center of the two; the paper pressing elastic arm 12 is rotatably connected to the shell 11 through the connection center. In a normal state, the end of the driving elastic arm 122 is fixed to the shell 11. For example, the driving elastic arm 122 can be moved outward for a certain stroke, and then a certain elastic force is generated and then it is tripped on the protruding column of the shell 11 (it should be noted here that Figure 1 The driving elastic arm 122 in the paper pressing arm 121 is in an unstuck state). Since the paper pressing arm 121 is connected to the driving elastic arm 122, under the action of the driving elastic arm 122, the end of the paper pressing arm 121 moves inward, and the sticker 13 can be pressed and positioned at a fixed position in the sticker channel, such as pressed on a column or a wall 14. The above-mentioned label box 1 has the characteristic of being unlockable due to the presence of the elastic driving elastic arm 122. The present invention designs a special matching label printer for the above-mentioned label box 1. When the label box 1 is installed in the label printer, the original positioning function can be unlocked without affecting the printing process and consuming too much power, while achieving effective positioning.

[0027] Cooperate Figure 2-5 As shown, this embodiment provides a label printer with a label box sticker positioning and unlocking function, including a machine body 2 that can be built-in with a label box 1, and a print head 21 is arranged on the machine body 2 inside the sticker channel of the label box 1; a rubber roller bracket 23 with a rubber roller 22 is movably installed on the side of the machine body 2, corresponding to the position of the print head; and an unlocking pressing block 24 is movably installed on the side of the machine body 2, at a position corresponding to the driving elastic arm 122 of the label box 1. The function of the rubber roller bracket 23 is to drive the rubber roller 22 to press the sticker 13 inward to the print head 21, so that it can effectively position the sticker 13. The function of the unlocking pressing block 24 is to press the driving elastic arm 122 inward, thereby driving the end of the paper pressing arm 121 to tilt up and separate from the sticker 13, so as to achieve unlocking, without affecting the printing process and consuming additional power.

[0028] When the label box 1 is placed in the machine body 2, the rubber roller bracket 23 and the unlocking block 24 are not in action, and the sticker positioning function is still valid. In order to achieve unlocking, the rubber roller bracket 23 and the unlocking block 24 are equipped with corresponding triggering members, which can be triggered by the triggering members. In this embodiment, a first trigger member 31 and a second trigger member 32 are provided on the machine back cover 3 that is buckled with the machine body 2. The two are respectively wedge-shaped structures located on the side of the machine back cover 3 and facing downward; for example, it is preferred that the first trigger member 31 is a long wedge structure and the second trigger member 32 is a short wedge structure; two sockets 25 and 26 are provided on the top of the side of the machine body 2; when the machine back cover 3 is pressed downward onto the machine body 2, the first trigger member 31 is first inserted from the socket 25 and contacts the rubber roller bracket 23, driving the rubber roller 22 to press the sticker 13 onto the print head 21; the second trigger member 32 is then inserted from the socket 26, and the machine back cover 3 is continued to be pressed for a certain stroke, and the second trigger member 32 contacts the unlocking pressure block 24, triggering the unlocking pressure block 24 to press the driving elastic arm 122 inwardly, and after the driving elastic arm 122 is subjected to force, the paper pressing elastic arm 12 itself rotates, driving the end of the paper pressing arm 121 to tilt up and detach from the sticker 13, thereby realizing the unlocking of the sticker positioning function.

[0029] In this embodiment, as a preferred solution, the rear end of the rubber roller bracket 23 is installed on the machine body 2 through the vertical rotating shaft 27, and the rubber roller 22 is arranged on the inner side of the front end of the rubber roller bracket 23; the rear end of the unlocking pressure block 24 is also installed on the vertical rotating shaft 27; the rubber roller bracket 23 and the unlocking pressure block 24 can rotate around the vertical rotating shaft 27 under the action of triggering, and can return to their original position when the triggering action is cancelled.

[0030] It can be seen from the above embodiments that the first trigger member 31 and the second trigger member 32 are preferably located on the machine rear cover 3. When the machine rear cover 3 is buckled with the machine body 2, the downward linear motion of the first trigger member 31 and the second trigger member 32 is converted into the rotation of the rubber roller bracket 23 and the unlocking block 24.

[0031] Based on the unlocking principle of the present invention, those skilled in the art can know that as long as a trigger is provided on the label printer, the trigger is provided on the machine body 2 or the machine back cover 3, and the same function can be achieved. In addition, based on the above principle, it can also be replaced by converting the downward linear motion of the first trigger 31 and the second trigger 32 into the sliding of the rubber roller bracket 23 and the unlocking block 22; or the first trigger 31 and the second trigger 32 are converted into the rotation or sliding of the rubber roller bracket 23 and the unlocking block 24 through rotation, so as to achieve the purpose of unlocking.

[0032] In addition, the above embodiment preferably adopts the asynchronous triggering mode of the first triggering member and the second triggering member, the first triggering member is the first triggering member, and the second triggering member is the second triggering member, through which the rubber roller can be pressed first and then unlocked to avoid positioning changes in the process. Of course, as an alternative, the first triggering member and the second triggering member can also be triggered synchronously.

[0033] In summary, the label printer with the label box sticker positioning and unlocking function of the present invention, before printing, the stickers in the label box are positioned in a stable and accurate position, after the label box is loaded into the machine, on the basis that the accurate position of the stickers does not change, the positioning function of the stickers is unlocked, the power required for printing does not increase, and the stickers are pressed by the print head and the rubber roller for printing, which ensures the accuracy of the printing position and avoids unnecessary waste of stickers. When printing is completed, after the label box consumables are taken out, the sticker positioning function continues to effectively press and constrain the stickers, always ensuring that the stickers are positioned in the accurate position required for printing, thereby improving the utilization rate of the stickers.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
