[0042] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0043] like Figures 1-4 As shown, the first aspect of this application provides a mechanism support assembly 100, which includes a support bracket 110 and a mounting bracket 120. The mounting bracket 120 is used to mount components of the label printer 200, and the support bracket 110 is used to support the mounting bracket 120, thereby improving the structural strength of the mechanism support assembly 100. The support bracket 110 can serve as the skeleton of the label printer 200.

[0044] The mounting bracket 120 is arranged at least partially inside the supporting bracket 110, and the supporting bracket 110 can support the mounting bracket 120. The mounting bracket 120 comprises a carbon ribbon cartridge mounting bracket 121, which comprises a first part 1211 and a second part 1212. The first part 1211 is formed with a dispensing shaft accommodating cavity 121a for accommodating a dispensing shaft, and the second part 1212 is formed with a winding shaft accommodating cavity 121b for accommodating a winding shaft. The dispensing shaft accommodating cavity 121a and the winding shaft accommodating cavity 121b are arranged in a spaced manner.

[0045] The first part 1211 and the second part 1212 are connected with the supporting bracket 110, so that the supporting bracket 110 can support the first part 1211 and the second part 1212 at the same time, thereby improving the strength of the first part 1211 and the second part 1212. The first part 1211 and the second part 1212 are arranged integrally, so that the carbon ribbon cartridge mounting bracket 121 is arranged integrally, and the carbon ribbon cartridge mounting bracket 121 can simultaneously mount the dispensing shaft and the winding shaft, that is, the structure of the mounting bracket 120 is relatively simple, the number of materials can be reduced, the storage and transportation convenience can be improved, and the connection between the mounting bracket 120 and the supporting bracket 110 is relatively simple, the assembly difficulty can be reduced, and the assembly efficiency can be improved.

[0046] As shown in FIG. 1, Figure 2 In some embodiments, the dispensing shaft accommodating cavity 121a has a first opening 121c, and the winding shaft accommodating cavity 121b has a second opening 121d. The first opening 121c and the second opening 121d are arranged on the same side of the carbon ribbon cartridge 220. The first opening 121c is used for inserting and mounting the dispensing shaft of the carbon ribbon cartridge 220 into the dispensing shaft accommodating cavity 121a, and the second opening 121d is used for inserting and mounting the winding shaft of the carbon ribbon cartridge 220 into the winding shaft accommodating cavity 121b. The first opening 121c and the second opening 121d are arranged on the same side of the carbon ribbon cartridge 220, so that the dispensing shaft and the winding shaft of the carbon ribbon cartridge 220 can be conveniently inserted into the corresponding cavities of the carbon ribbon cartridge mounting bracket 121. The dispensing shaft and the winding shaft can be mounted from the same side, so that the mounting is more convenient.

[0047] In some embodiments, the structural strength of the supporting bracket 110 is greater than the structural strength of the mounting bracket 120. Because the structural strength of the supporting bracket 110 is high, the relative movement or deformation between the first part 1211 and the second part 1212 is less likely to occur, that is, the relative position relationship between the winding shaft and the dispensing shaft is less likely to change, so that the carbon ribbon is relatively flat and less likely to wrinkle, thereby ensuring the printing effect.

[0048] The support bracket 110 is exemplarily a metal bracket, thereby having high structural strength, so as to provide better support for the support bracket 110. The mounting bracket 120 is exemplarily a plastic bracket, thereby being light in quality, low in cost, and low in processing difficulty, and capable of being injection molded into various complex shapes.

[0049] As shown in Figure 3 some embodiments, the support bracket 110 includes a bottom plate 111 and a side plate 112 connected with the bottom plate 111, and the bottom plate 111 and the side plate 112 are optionally arranged perpendicularly. The first part 1211 has a first plane 121e on a side opposite to the bottom plate 111, and the first plane 121e is in contact with the bottom plate 111. The plane contact can ensure that the connecting surface is uniformly stressed, avoid deformation or wear caused by local stress concentration, and has a large plane contact area, so as to efficiently transmit pressure, tension or shear force, and the connection is stable, easy to align and install, and reduces assembly time.

[0050] As shown in Figure 3 some embodiments, the second part 1212 has a second plane 121f on a side opposite to the bottom plate 111, and the second plane 121f is in contact with the bottom plate 111. The plane contact can ensure that the connecting surface is uniformly stressed, avoid deformation or wear caused by local stress concentration, and has a large plane contact area, so as to efficiently transmit pressure, tension or shear force, and the connection is stable, easy to align and install, and reduces assembly time.

[0051] As shown in Figure 3 some embodiments, the support bracket 110 includes a bottom plate 111 and a side plate 112 connected with the bottom plate 111, and the first part 1211 has a third plane 121g on a side opposite to the side plate 112, and the third plane 121g is in contact with the side plate 112. The plane contact can ensure that the connecting surface is uniformly stressed, avoid deformation or wear caused by local stress concentration, and has a large plane contact area, so as to efficiently transmit pressure, tension or shear force, and the connection is stable, easy to align and install, and reduces assembly time.

[0052] Moreover, the first part 1211 is in abutment with the first plane 121e and the third plane 121g at the same time, so as to achieve better limiting effect.

[0053] As shown in Figure 3 some embodiments, the second part 1212 has a fourth plane 121h on a side opposite to the side plate 112, and the fourth plane 121h is in contact with the side plate 112. The plane contact can ensure that the connecting surface is uniformly stressed, avoid deformation or wear caused by local stress concentration, and has a large plane contact area, so as to efficiently transmit pressure, tension or shear force, and the connection is stable, easy to align and install, and reduces assembly time.

[0054] Moreover, the second part 1212 is in contact with the second plane 121f and the fourth plane 121h at the same time, and thus better limiting effect can be achieved.

[0055] In some embodiments, the side plate 112 is provided with a first through hole 112a corresponding to the dispensing shaft accommodating cavity 121a, and is provided with a second through hole 112b corresponding to the winding shaft accommodating cavity 121b. The first through hole 112a is used for inserting and mounting the dispensing shaft of the carbon tape box 220 into the dispensing shaft accommodating cavity 121a, and the second through hole 112b is used for inserting and mounting the winding shaft of the carbon tape box 220 into the winding shaft accommodating cavity 121b, so that the dispensing shaft accommodating cavity 121a of the first part 1211 and the winding shaft accommodating cavity 121b of the second part 1212 can be communicated with the outside, facilitating the insertion of the carbon tape box 220.

[0056] As shown in the drawings, Figure 2 In some embodiments, the first part 1211 and the second part 1212 form an installation space 121i therebetween, and the machine core support assembly 100 further comprises a printing part 130, which is arranged in the installation space 121i and separates the first part 1211 and the second part 1212 from each other. The printing part 130 is arranged in the installation space 121i, and the structure is relatively compact. Moreover, the printing part 130 is arranged between the unwinding shaft and the winding shaft, and can be conveniently in contact with the carbon tape, thereby facilitating printing.

[0057] In some embodiments, both ends of the printing part 130 are connected with the support bracket 110, that is, both ends of the printing part 130 can be stressed, so that the connection strength between the printing part 130 and the support bracket 110 is high, the weight and movement load of the printing part 130 are evenly distributed to the support bracket 110, the additional wear of the transmission components such as guide rails and bearings is reduced, and the service life of the equipment is prolonged. Moreover, the two-end fixation can effectively suppress the vibration generated during the high-speed movement of the printing head 131, the structure of the printing part 130 is relatively stable, the printing precision is ensured, the printing effect is good, and the inclination or deformation caused by unilateral stress is avoided.

[0058] As shown in the drawings, Figure 1 In some embodiments, the carbon tape box mounting bracket 121 is further provided with a carbon tape insertion slot 121j, which is in communication with the dispensing shaft accommodating cavity 121a and the winding shaft accommodating cavity 121b, and is used for inserting the carbon tape of the carbon tape box 220. The carbon tape insertion slot 121j is designed to make the carbon tape installation process more intuitive, and the user only needs to align the carbon tape with the slot and push it in to complete the installation without complicated operation, such as manual threading.

[0059] In some embodiments, the difference between the dimension of the ribbon insertion slot 121j in the ribbon thickness direction and the thickness dimension of the ribbon is greater than or equal to 2mm, thereby preventing the ribbon from rubbing against the groove wall of the ribbon insertion slot 121j and facilitating insertion into the ribbon box 220.

[0060] like Figure 3 As shown, in some embodiments, the support bracket 110 includes a base plate 111 and a side plate 112 connected to the base plate 111. The mechanism bracket assembly 100 also includes a print head 131, which is rotatably connected to the side plate 112. The print head 131 has a first position and a second position. When the print head 131 is in the first position, the print head 131 is outside the ribbon insertion slot 121j, thereby avoiding the print head 131 from affecting the assembly of the ribbon cartridge 220 and preventing the print head 131 from rubbing against the ribbon.

[0061] When the print head 131 is in the second position, the print head 131 is located in or through the ribbon insertion slot 121j to press against the ribbon. At this time, the print head 131 can lift the ribbon and expose it in the printing channel, thereby realizing printing.

[0062] like Figure 4 As shown, in some embodiments, the support bracket 110 includes a base plate 111 and a side plate 112 connected to the base plate 111. The mechanism bracket assembly 100 also includes a first circuit board 140, a print head 131, and a first conductive element 150. The first circuit board 140 is disposed on the back of the base plate 111. The print head 131 is electrically connected to the first circuit board 140 through the first conductive element 150. At least one of the first part 1211 and the second part 1212 is provided with a first wire through hole, through which the first conductive element 150 passes. By directly mounting the first circuit board 140 on the support bracket 110, there is no need to provide a circuit board mounting bracket 120 for mounting the first circuit board 140. This simplifies the structure of the mounting bracket 120, reduces the amount of materials, and improves the convenience of storage and transportation. Moreover, the connection between the mounting bracket 120 and the support bracket 110 is also simple, reducing assembly difficulty and improving assembly efficiency.

[0063] By providing a first wire hole, the first conductive element 150 can be electrically connected to the first circuit board 140 via a shorter route.

[0064] like Figure 4As shown, in some embodiments, the first conductive element 150 is a flexible circuit board. The flexible circuit board can be bent, folded, or rolled to adapt to irregular spaces inside the equipment. It can operate stably even under repeated bending or vibration. The flexible substrate of the circuit board absorbs mechanical stress, reducing solder joint breakage or component detachment caused by vibration or impact. The thickness of the flexible circuit board is typically 0.1–0.3 mm, significantly reducing equipment weight. Furthermore, the flexible circuit board supports multi-layer wiring and high-density component layout, reducing the use of connectors and cables, further minimizing equipment size. The flexible circuit board can be directly soldered to a rigid PCB or components, reducing the number of connectors and cables and lowering assembly complexity. The flexible circuit board facilitates modular design, simplifying equipment maintenance or upgrades.

[0065] In some embodiments, the first conductive element 150 is spaced apart from both the delivery shaft and the take-up shaft, thereby avoiding interference with the installation of the ribbon cartridge 220 and preventing damage to the first conductive element 150.

[0066] like Figure 2 As shown, in some embodiments, the mounting bracket 120 includes a micro switch mounting bracket 122 integrally formed with the ribbon cartridge mounting bracket 121. The mechanism bracket assembly 100 also includes a micro switch 160, which is mounted on the micro switch mounting bracket 122 and is used to detect whether the printhead 131 has been lifted. By making the micro switch mounting bracket 122 integrally formed with the ribbon cartridge mounting bracket 121, the structure of the mounting bracket 120 can be simplified, reducing the amount of materials and improving the convenience of storage and transportation. Moreover, the connection between the mounting bracket 120 and the support bracket 110 is also simpler, reducing assembly difficulty and improving assembly efficiency.

[0067] In some embodiments, the micro switch mounting bracket 122 obstructs the micro switch 160, thereby ensuring that the micro switch 160 can only be touched by the printhead 131 and is difficult to be touched by other components, thus preventing other components from accidentally touching the micro switch 160. Alternatively, the micro switch mounting bracket 122 limits the micro switch 160 to ensure that the micro switch 160 is accurately positioned within the micro switch mounting bracket 122, preventing accidental triggering or failure due to loosening or misalignment.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the movement support assembly 100 further includes a micro switch 160, a second circuit board 170, and a second conductive element 180. The micro switch 160 and the second circuit board 170 are electrically connected through the second conductive element 180. The mounting bracket 120 is provided with a second wire hole through which the second conductive element 180 passes. By providing the second wire hole, the second conductive element 180 can be electrically connected to the second circuit board 170 via a shorter route.

[0069] In some embodiments, the second conductive element 180 is disposed inside the mounting bracket 120 and is shielded by at least one of the mounting bracket 120 and the support bracket 110, thereby preventing the second conductive element 180 from being exposed, preventing the user from touching the second conductive element 180 during use, reducing the probability of damage to the second conductive element 180, and improving the safety of the second conductive element 180.

[0070] like Figure 5 and Figure 6 As shown, a second aspect of this application provides a label printer 200, which includes a body 210, a printhead support assembly 100, and a ribbon cartridge 220. The printhead support assembly 100 is disposed on the body 210, and the ribbon cartridge 220 is disposed on the printhead support assembly 100.

[0071] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
