[0036] Preferably, in the embodiments of the present invention, the first direction, the second direction, and the third direction are orthogonal to each other pairwise.

[0037] Now in combination with Figures 1 to 7 the structure and function of the solution of the present application will be described in detail.

[0038] First Embodiment:

[0039] An embodiment of the present invention provides a printing cartridge 1, which can be used to load and fix a printing tape assembly 2. In combination with Figure 2 , Figure 3 as shown, the cartridge body 1 includes a frame 11. The frame 11 has a feeding channel, a U-shaped area 111, and a U-shaped groove 112. Among them, the U-shaped area 111 has a first opening facing the negative direction side of the second direction, and the U-shaped groove 112 has a second opening facing the positive direction side of the second direction. The U-shaped groove 112 has a pressing device in the second direction. In this embodiment, the pressing device is a pressing plate 12. A tensioning portion 13 is provided at the bottom of the U-shaped area 111. The feeding path 3 includes a first path 31 and a second path 32 communicating with the first path 31. When observed from the first direction, along the second direction, the first path 31 is located on the positive direction side of the tensioning portion 13. Among them, when observed from the first direction, along the second direction, the pressing plate 12 is located on the negative direction side of the tensioning portion 13. The printing cartridge 1 of this embodiment further includes a printing tape storage bin 113 and a printing tape recycling bin 114. One end of the printing tape 21 is fixed and wound on a storage roller 22, and the storage roller 22 is installed in the printing tape storage bin 113 to fix one end of the printing tape 21. The other end of the printing tape 21 is fixed and wound on a recycling roller 23, and the recycling roller 23 is installed in the printing tape recycling bin 114 to fix the other end of the printing tape 21. The two ends of the printing tape 21 are respectively fixed on the storage roller 22 and the recycling roller 23, so that a part of it can be placed in the first path 31 and the second path 32.

[0040] In this embodiment, the pressing plate 12 is inserted into the frame 11 from the positive direction side of the frame 11 in the second direction. When the pressing plate 12 is fixed on the frame 11, the above-mentioned second path 32 is formed on the frame 11. Among them, along the second direction, the second path 32 is located on the negative direction side of the pressing plate 12. In combination with Figure 1, it can be seen that in the prior art, the pressing plate 12 and the frame 11 are integrally formed. When loading the print tape assembly 2, at least one end of the print tape 21 needs to be unfixed on the shaft, and the unfixed end is passed through the commutation hole so that the print tape can be partially located on the first path and partially located on the second path. The pressing plate 12 of this embodiment can be installed on the frame 11 from the positive side of the frame 11 after at least part of the print tape 21 is loaded onto the frame 11, and part of the print tape 21 is limited on the second path 32, so that the print tape 21 can feed along the second path 32. And the print tape 21 can be supported on the tensioning part 13 and the pressing plate 12 to realize feeding along the feeding path 3. Combined with Figure 1 , the above structure can make the installation of the print tape assembly 2 more convenient, without passing the print tape 21 through the commutation hole S1' and then fixing the print tape 21 on a shaft. At the same time, it can solve the problem that the print tape 21 will be skewed in the third direction due to installation errors during the process of first passing the print tape 21 through the commutation hole S1' and then fixing the print tape 21 to the shaft.

[0041] Preferably, the pressing plate 12 is made of a metal material. For example, it is formed by stamping and processing a metal plate, or integrally formed by alloy casting. It can be understood that in other embodiments, the pressing plate 12 can be integrally formed of a resin material.

[0042] Second Embodiment:

[0043] Based on the first embodiment, in the second embodiment, combined with Figure 4 , the pressing plate 12 includes a substrate 51 and guide parts 52 located at both ends of the substrate 51 along the first direction. Combined with Figure 5 , the guide parts 52 extend along the positive side of the second direction. The substrate 51 has a second path 32 on the negative side along the second direction. A third path 33 for connecting the first path 31 and the second path 32 is formed on one side of one guide part 52 away from the other guide part 52. Among them, the substrate 51 and the guide parts 52 are connected by an arc transition. It can be understood that the guide parts 52 can be used as baffles to separate the U-shaped groove 112 and the print tape assembly 2.

[0044] In the second embodiment, combined with Figure 5, a bump 511 is provided at the bottom of the pressing plate (i.e., the substrate 51 is located on one side of the third path 33). The bump 511 is close to the storage bin side. The bump 511 gradually inclines and protrudes from left to right. Specifically, the bump 511 protrudes toward the third path 33 side, so that the printing tape 21 is tensioned and supported on the bump 511 and the tensioning portion 13. The bump 511 has an arc-shaped contact portion 511A at the junction of the second path 32 and the third path 33, so that the printing tape 21 can be supported on the tensioning portion 13 and the contact portion 511A and slidably cooperate with the contact portion 511A. The bump 511 that gradually inclines and protrudes from left to right makes the printing tape 21 contact the tensioning portion 13 of the pressing plate 12 and enter the second path 32 unobstructed. Along this extension direction, it then winds around the recovery roller 23, and part of the printing tape 21 is tensioned in the second path 32 by the recovery roller 23 and the tensioning portion 13. Among them, the bump 511 that gradually inclines from left to right reduces the contact area between the printing tape 21 and the pressing plate 12 to reduce the frictional resistance. The contact portion 511A configured as an arc-shaped structure is used to guide and slide the printing tape 21, and achieves the technical effect that the printing tape 21 will not be scratched, or the heat-resistant coating or thermal transfer ink on the surface of the printing tape 21 will not be scraped off.

[0045] In the second embodiment, with reference Figure 6 , a rectangular hollow 14 is provided on the frame. The rectangular hollow 14 is adjacent to the storage bin. The first path 31 is provided on the rectangular hollow 14. Specifically, the first path 31 is located on the positive direction side of the rectangular hollow 14 along the second direction. It can be understood that the rectangular hollow 14 is used for the transferred image during printing. Therefore, a larger space is required on the feeding path of the printing tape 21. To achieve thermal transfer and reduce the contact area between the printing tape 21 and the frame 11, the bottom of the U-shaped area 111 is designed in a rectangular hollow shape. Along the first direction, there are tensioning ends at both ends of the rectangular hollow 14 of the U-shaped area 111, and the two tensioning ends constitute the tensioning portion 13. The positions on the two tensioning portions 13 that contact the printing tape 21 are configured as arc-shaped structures along the feeding path of the printing tape 21, which are used to guide and slide the printing tape 21, and achieve the technical effect that the printing tape 21 will not be scratched, or the heat-resistant coating or thermal transfer ink on the surface of the printing tape 21 will not be scraped off. It can be understood that in this embodiment, the two tensioning portions 13 are formed on the frame 11, that is, the frame 11 is integrally formed with the two tensioning portions 13 when it is molded.

[0046] Other characteristics not mentioned in the second embodiment may be the same as those in the first embodiment, and the deformable implementation manners that can be adopted and their beneficial effects may also be the same as those in the first embodiment, so they will not be elaborated here.

[0047] Third embodiment:

[0048] Based on the second embodiment, in the third embodiment, in combination with Figure 7, the first end of the pressing plate 12 in the third direction has a first fastening member 43. The first fastening member 43 includes a first clamping portion 431 and a second clamping portion 432. The first clamping portion 431 and the second clamping portion 432 are formed at the first end of the substrate 51 in the third direction, and the first end is the end of the substrate 51 on the positive side of the third direction. The second clamping portion 432 is formed and supported on the first clamping portion 431, and the first clamping portion 431 and the second clamping portion 432 are arranged at intervals in the second direction. Along the second direction, a clamping groove 433 is formed between the first clamping portion 431 and the second clamping portion 432.

[0049] In the third embodiment, in combination with Figure 8 , a second fastening member 44 is provided in the U-shaped groove 112. The second fastening member 44 is used to support and fasten the first fastening member 43. The second fastening member 44 includes a pressure-bearing portion 441. The first clamping portion 431 and the second clamping portion 432 can clamp the pressure-bearing portion 441 in the middle during the movement process in the positive direction of the third direction, that is, the pressure-bearing portion 441 is inserted into the clamping groove 433, and the first end of the pressing plate 12 is supported on the pressure-bearing portion 441. Among them, the first clamping portion 431 and the second clamping portion 432 fix the first end of the pressing plate 12 by clamping on the pressure-bearing portion 441.

[0050] In the third embodiment, the second fastening member 44 further includes a limiting convex portion 442. The limiting convex portion 442 extends and protrudes in the positive direction of the third direction relative to the pressure-bearing portion 441, and the U-shaped groove 112 includes two limiting convex portions 442 located at both ends in the first direction. A limiting groove 443 for accommodating a part of the first fastening member 43 is formed between the two limiting convex portions 442. Among them, the limiting groove 443 is used to limit the position of the first fastening member 43 on the frame 11, so that the first end of the pressing plate 12 will not have too much inclination in the first direction.

[0051] In the third embodiment, in combination with Figure 7 and Figure 8, a limiting hole 45 is formed in the pressing plate 12. The limiting hole 45 is formed at the second end of the substrate 51 along the third direction, and the second end is the end of the substrate 51 on the negative direction side of the third direction. There is a first supporting portion 423 in the U-shaped groove 112. The first supporting portion 423 is formed at the bottom of the U-shaped groove 112 for supporting the second end of the substrate 51, and a limiting convex post 46 is arranged on the first supporting portion 423. The limiting convex post 46 can pass through the limiting hole 45 to limit the position of the second end of the pressing plate 12 relative to the frame 11, that is, the limiting convex post 46 and the limiting hole 45 cooperate to limit the position of the second end of the pressing plate 12 in the first direction and the third direction. Among them, the limiting convex post 46 is adapted to the limiting hole 45. For example, the limiting convex post 46 is a cylindrical structure, the limiting hole 45 is a circular hole structure adapted to the cylindrical structure, or the limiting convex post 46 is a polygonal columnar structure, and the limiting hole 45 is a polygonal hole adapted to the polygonal columnar structure.

[0052] In the third embodiment, the pressing plate 12 moves along the third direction so that the first fastening member 43 is clamped on the second fastening member 44, and the continuous movement of the pressing plate 12 is restricted by inserting the limiting convex post 46 into the limiting hole 45, and part of the first fastening member 43 is located in the limiting groove 443 to limit the position of the first end of the pressing plate 12 in the first direction. At the same time, the first fastening member 43 and the second fastening member 44 determine the position of the pressing plate 12 relative to the frame 11 in the second direction.

[0053] Preferably, in this embodiment, a hollow groove 434 is formed in the first fastening member 43 so that when the first fastening member 43 is clamped on the second fastening member 44, part of the pressure-bearing portion 441 can be exposed, so as to facilitate pushing the pressing plate 12 in the positive direction of the third direction by leveraging the pressure-bearing portion 441 when the pressing member 12 needs to be disassembled.

[0054] Other characteristics not mentioned in the third embodiment may be the same as those in the first embodiment and the second embodiment, and the deformable implementation manners that can be adopted and their beneficial effects may also be the same as those in the first embodiment and the second embodiment, so they will not be elaborated here.

[0055] Fourth embodiment:

[0056] Based on the second embodiment or the third embodiment, in the fourth embodiment, in combination Figure 9The clamping plate 12 includes a first limiting member 41, which is located at the second end of the substrate 51 along the third direction. The first limiting member 41 includes a limiting protrusion 411, which is formed on the substrate 51. The limiting protrusions 411 are respectively provided on both sides of the substrate 51 along the first direction, and the limiting protrusions 411 extend in the direction away from the substrate 51 along the first direction. The first limiting member 41 includes a toggle portion 412, which is a plate-like structure extending in the positive direction of the second direction. Preferably, the end of the toggle portion 412 along the positive direction of the second direction is provided with a bending portion, which is formed by a curling process or formed on the toggle portion 412 by an integral molding method. The second end is an end of the substrate 51 on the negative direction side of the third direction.

[0057] In the fourth embodiment, combined with Figure 10 , the U-shaped groove 112 has a second limiting member 42, the second limiting member 42 includes a support portion 423, the support portion 423 is a plate-like structure, the surface of the support portion 423 is in contact with one end of the substrate 51 of the clamping plate 12 in the third direction, and specifically supports the second end of the first limiting member 41 on the clamping plate 12. The second limiting member 42 includes a limiting block 421 on the positive direction side of the supporting portion 423 along the second direction, and a limiting groove 422 sandwiched between the supporting portion 423 and the limiting block 421, and the limiting groove 422 can be inserted with a limiting protrusion 411 to limit the movable space of the clamping plate 12 at the second end of the first limiting member 41 in the second direction. Among them, the second limiting member 42 includes two limiting grooves 422 arranged at both ends of the U-shaped groove 112 along the first direction. It can be understood that in other embodiments, the limiting protrusion 411 is inserted into the limiting groove 422 so that the clamping plate 12 is fixed relative to the frame 11 at the second end of the first limiting member 41 along the first direction.

[0058] Preferably, in this embodiment, the second limiting member 42 includes a forming hole 424 provided on the support portion 423, which is used to expose the limiting groove 422 to the space on the negative side of the support portion 423 in the second direction, so as to facilitate the one-time forming of the limiting groove 422 and the limiting block 421, so that the limiting groove 422 can be formed without a core pulling action during the forming process. It is understandable that in other embodiments, the forming hole 424 can be cancelled and not configured.

[0059] It is understandable that in other embodiments, the first limiting member 41 can be configured at one end of the substrate 51 in the negative direction of the third direction, and the second limiting member 42 can also be configured at one end of the U-shaped groove 112 in the negative direction of the third direction to limit the first limiting member 41.

[0060] Other features not mentioned in the fourth embodiment may be the same as any one of the first to third embodiments, and the deformable embodiments that can be adopted and their beneficial effects may also be the same as any one of the first to third embodiments, so they will not be elaborated here.

[0061] Fifth Embodiment:

[0062] In the fifth embodiment, in combination with Figure 11 , Figure 12 and Figure 13 , the fourth embodiment is combined with the third embodiment. During the process of the pressing plate 12 moving along the third direction, the limiting lug 411 is inserted into the limiting groove 422 along the third direction, and the pressing plate 12 stops moving when the limiting convex column 46 is inserted into the limiting hole 45, so as to fix the pressing plate 12 on the frame 11. Among them, the limiting block 421 can be used to limit the moving space of the pressing plate 12 when the pressing plate 12 has a tendency to move along the first direction under the force of the printing tape 21.

[0063] Preferably, the second clamping portion 432 is configured as a leaf spring structure, that is, the second clamping portion 432 flexes and moves under an external force to clamp a part of the bearing portion 441. Further, it is preferred that the distance between the second clamping portion 432 and the first clamping portion 431 gradually decreases along the negative direction of the third direction, so that when the first fastening member 43 clamps on the bearing portion 441, the force generated by the flexural deformation of the second clamping portion 432 of the pressing plate 12 presses on the supporting portion 423 along the negative direction of the second direction.

[0064] In this embodiment, in combination with Figure 12 , the assembled printing tape assembly 2 is loaded into the frame 11 from the positive direction side in the second direction. Among them, the storage reel 22 fixes one end of the printing tape 21 and is fixedly installed in the printing tape storage bin 113, and the recovery reel 23 fixes the other end of the printing tape 21 and is fixedly installed in the printing tape recovery bin 114. At this time, a part of the printing tape 21 between the storage reel 22 and the recovery reel 23 is located on the positive direction side of the frame 11 in the second direction. At this time, referring to Figure 13 , the pressing plate 12 is loaded into the frame 11 from the positive direction side of the frame 11 in the second direction, and is pushed into the frame 11 along the positive direction of the third direction so that the pressing plate 12 is fastened to the frame.

[0065] It can be understood that the first limiting member 41, the second limiting member 42, the first fastening member 43, the second fastening member 44, the limiting hole 45 and the limiting convex column 46 constitute an installation mechanism for installing the pressing plate 12. Other features not mentioned in this embodiment may be the same as any one of the first to fourth embodiments, and the deformable embodiments that can be adopted and their beneficial effects may also be the same as any one of the first to fourth embodiments, so they will not be elaborated here.

[0066] Sixth Embodiment:

[0067] Different from the first embodiment, in the sixth embodiment, referring to Figure 14 and Figure 15 , in the first direction, the printing tape storage bin 113, the second path 32, the first path 31, and the printing tape recycling bin 114 are arranged in sequence. That is, the second path 32 is formed on the negative direction side of the U-shaped area 111 in the second direction. The first path 31 and the second path 32 are arranged offset in the second direction, and there is a third path 33 connecting the two between the first path 31 and the second path 32. A storage bin cover 62 and a pressing shaft 61 are arranged on the frame 11. The storage bin cover 62 has a pressing end 621, and the pressing end 621 extends from the storage bin cover 62 into the U-shaped area. There is a rectangular hollow 14 between the pressing end 621 and the pressing shaft 61.
