Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a detachable material tray. Background Technology

[0002] Current 3D printers use filament trays to hold filament rolls. These trays are typically a single, integrated structure, consisting of the tray body and a mounting cylinder for holding the filament rolls. Once the filament is used up, the tray is discarded and cannot be reused, resulting in waste. Utility Model Content

[0003] In view of this, the present invention provides a detachable tray to solve the above problems.

[0004] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes:

[0005] A detachable tray includes a first tray body, a second tray body, and a mounting cylinder. The mounting cylinder is disposed on the first tray body and is used to mount consumable rolls. The detachable tray also includes a limiting component, which is disposed on the second tray body. The second tray body is detachably connected to the mounting cylinder via the limiting component.

[0006] During the disassembly process of the second disc body from the mounting cylinder, the second disc body is only translated along the axial direction of the mounting cylinder, or the second disc body is only translated at a fixed angle to the axial direction of the mounting cylinder, so that the second disc body is separated from the end face of the consumable roll.

[0007] Implementing the embodiments of this utility model will have the following beneficial effects:

[0008] With the above-mentioned detachable tray, the second tray can be disassembled without rotating it. Instead, after disconnecting the limiting component from the mounting cylinder, the second tray can move directly along the axial direction of the mounting cylinder to separate from it. This allows the consumable rolls on the tray to be replaced, enabling the tray to be reused. Attached Figure Description

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] See appendix Figures 1 to 19 This utility model proposes a detachable material tray, including a first tray body 1, a second tray body 2, a mounting cylinder 3, and a limiting component 4. The first tray body 1 and the second tray body 2 are parallel to each other. The first tray body 1 has a first mounting hole 101, and the second tray body 2 has a second mounting hole 201. The mounting cylinder 3 is fixed to the first tray body 1. The limiting component 4 allows for a detachable connection between the mounting cylinder 3 and the second tray body 2. When the mounting cylinder 3 and the second tray body 2 are connected, the mounting cylinder 3 communicates with the first mounting hole 101 and the second mounting hole 201, which are used for corresponding mounting components in the 3D printer to pass through. A filament roll 1000 can be sleeved on the outside of the mounting cylinder 3; therefore, both the mounting cylinder 3 and the filament roll 1000 are located between the first tray body 1 and the second tray body 2. A conventional filament roll 1000 typically winds filament thread 1002 onto an inner cylinder 1001, which is usually a cardboard tube or a plastic tube.

[0041] Furthermore, a first binding hole 102 is provided on the first disc body 1, and a second binding hole 202 is provided on the second disc body 2. The positions of the first binding hole 102 and the second binding hole 202 correspond to each other. The height of both the first binding hole 102 and the second binding hole 202 is greater than the thickness of the consumable roll 1000, where the thickness of the consumable roll 1000 refers to its thickness in the radial direction 303 of the mounting cylinder 3. Binding tools 2000, such as adhesive tape, cable ties, and Velcro, can be used to bind the consumable roll 1000 by passing through the first binding hole 102 and the second binding hole 202.

[0042] Specifically, the limiting component 4 is disposed on the second disc body 2, and the second disc body 2 is detachably connected to the mounting cylinder 3 through the limiting component 4. The limiting component 4 can be connected to the mounting cylinder 3 by means of snap-fit, interlocking, bolt connection, etc. The entire disassembly of the second disc body 2 is divided into two processes: the unlocking process between the limiting component 4 and the mounting cylinder 3, and the separation process between the second disc body 2 and the mounting cylinder 3. Furthermore, when the limiting component 4 is connected to the mounting cylinder 3 by a snap-fit ​​or interlocking structure, the user only needs to apply a linear force to unlock the limiting component 4. The direction of this linear force can be along the axial direction 302, radial direction 303, or oblique direction at a fixed angle to the axial direction 302 of the mounting cylinder 3.

[0043] During the unlocking process between the limiting component 4 and the mounting cylinder 3, and the separation process between the second disc 2 and the mounting cylinder 3, the second disc 2 only undergoes translation along the axial direction 302 of the mounting cylinder 3, or only undergoes oblique translation at a fixed angle to the axial direction 302 of the mounting cylinder 3, so that the second disc 2 detaches from the end face of the consumable roll 1000. In both processes, the second disc 2 does not come into contact with the strapping tool 2000, thus preventing the edge of the second strapping hole 202 from abutting against the strapping tool 2000.

[0044] In other words, when the limiting component 4 is connected to the mounting cylinder 3, the second disc 2 and the mounting cylinder 3 are fixed on the circumferential direction 301 of the mounting cylinder 3, that is, the second disc 2 and the mounting cylinder 3 do not rotate relative to each other.

[0045] In use, first, place the complete filament roll 1000 onto the mounting cylinder 3. Then, bring the second disc 2 close to the mounting cylinder 3 until the limiting component 4 is connected to the mounting cylinder 3. The first disc 1 and the second disc 2 then clamp the filament roll 1000 together. Next, remove the original tape from the filament roll 1000. Then, install the detachable disc into the 3D printer. Finally, align the filament liner 1002 with the 3D printer's feeding mechanism. The distance between the first disc 1 and the second disc 2 is approximately equal to the width of the filament roll 1000, primarily to prevent the filament liner 1002 on the filament roll 1000 from becoming loose.

[0046] When a user needs to change the color of consumables, and the consumable roll 1000 on the removable tray has not yet been used up, the user can first use the bundling tool 2000 to pass through the first bundling hole 102 and the second bundling hole 202 to bundle the consumable roll 1000. Then, the connection between the limiting component 4 and the mounting cylinder 3 is released, and the second tray 2 is pulled away along the axial direction 302 of the mounting cylinder 3. The bundled consumable roll 1000 can then be removed from the mounting cylinder 3. After replacing the new consumable roll 1000, the aforementioned installation steps can be repeated. During this process, since the second tray 2 and the bundling tool 2000 do not come into contact, mutual interference between the second tray 2 and the bundling tool 2000 can be prevented, and the bundling tool 2000 can also be prevented from being damaged.

[0047] In summary, the second disc 2 in the detachable tray does not need to be rotated during disassembly. Instead, after the connection between the limiting component 4 and the mounting cylinder 3 is released, the second disc 2 can move directly along the axial direction 302 of the mounting cylinder 3 to separate from the mounting cylinder 3. During the disassembly process, the second disc 2 and the mounting cylinder 3 do not need to rotate relative to each other, which prevents the second disc 2 from rubbing against the consumable roll 1000. At the same time, it also avoids interference from the strapping tool 2000 on the movement of the second disc 2, making it more convenient to use.

[0048] In some embodiments, the limiting component 4 includes a docking member 41 and a snap-fit ​​member 42 mounted on the docking member 41. The docking member 41 is arranged in a ring on the side of the second disc 2 facing the first disc 1. The docking member 41 is coaxially docked with the mounting cylinder 3, and the snap-fit ​​member 42 snaps into the mounting cylinder 3. Specifically, the mounting cylinder 3 has an insertion groove 31 provided along the axial direction 302 of the mounting cylinder 3. The shape of the insertion groove 31 corresponds to the design of the docking member 41, so that the docking member 41 can be at least partially inserted into the insertion groove 31.

[0049] Regarding the issue of preventing the second disc 2 from rotating relative to the mounting cylinder 3, in some embodiments, when the docking member 41 is inserted into the insertion slot 31, the rotation of the docking member 41 around the circumference 301 of the mounting cylinder 3 is restricted. Furthermore, a snap-fit ​​member 42 is used to snap the docking member 41 into the mounting cylinder 3, thus preventing the docking member 41 from separating along the axial direction 302 of the mounting cylinder 3. For example, the docking member 41 may be annular in shape but its surface may be non-circular, and the insertion slot 31 may also be non-circular. Therefore, when the docking member 41 is inserted into the insertion slot 31, it cannot rotate relative to the mounting cylinder 3. Alternatively, the docking member 41 may be composed of multiple spaced-apart components, and the insertion slot 31 may contain multiple spaced-apart grooves. Each component is inserted into one of these grooves, which also prevents the docking member 41 from rotating relative to the mounting cylinder 3.

[0050] Understandably, in other embodiments, a plug-in groove 31 may also be provided on the docking member 41, into which the mounting cylinder 3 is inserted.

[0051] Understandably, regarding the issue of preventing the second disc 2 from rotating relative to the mounting cylinder 3, in other embodiments, both the docking member 41 and the insertion slot 31 can be designed as annular, and the snap-fit ​​structure of the snap-fit ​​member 42 and the mounting cylinder 3 can be used to prevent the docking member 41 from rotating relative to the mounting cylinder 3.

[0052] For details regarding the detachable connection structure of the snap-fit ​​connector 42 and the mounting sleeve 3, please refer to the appendix. Figure 6 and 7 As in Embodiment 1, a locking port 32 is provided on the mounting cylinder 3, specifically the locking port 32 is provided along the radial direction 303 of the mounting cylinder 3; the snap-fit ​​part 42 includes an integrally connected driving part 421, snap-fit ​​part 422 and rotating part 423, and a mounting cavity 411 is provided in the mating part 41. The rotating part 423 is rotatably installed in the mounting cavity 411, and the rotation axis 4231 of the rotating part 423 is perpendicular to the axial direction 302 of the mounting cylinder 3. The drive part 421 is at least partially exposed from the mating member 41 and also from the side of the second disc 2 away from the first disc 1. The locking part 422 is oscillating about the rotating part 423 to extend into or disengage from the locking port 32. Driving the drive part 421 to oscillate corresponds to driving the locking part 422 to oscillate, and the locking part 422 has displacement in the radial direction 303 of the mounting cylinder 3. When the locking part 422 extends into the locking port 32, if an external force is applied to drive the second disc 2 away from the mounting cylinder 3, the locking part 422 will abut against the edge of the locking port 32 away from the first disc 1, thereby preventing the second disc 2 from further disengaging from the mounting cylinder 3. The limiting component 4 also includes an elastic member 43, which is located within the mounting cavity 411. One end of the elastic member 43 is connected to the mating member 41, and the other end is connected to the drive part 421 or the locking part 422. The elastic force of the elastic member 43 is used to drive the locking part 422 into the locking port 32. For example, see attached... Figure 6 As shown, the elastic element 43 is a compression spring, which connects one side wall of the mounting cavity 411 and the driving part 421. For example, see attached... Figure 7 As shown, the elastic element 43 is a torsion spring, which is sleeved on the rotating part 423 and connects to one side wall of the mounting cavity 411 and the snap-fit ​​part 422. In this embodiment, the limiting component 4 can be unlocked by applying a linear force along the radial direction 303 of the mounting cylinder 3 to the driving part 421. Then, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to separate the second disc 2 from the mounting cylinder 3.

[0053] For details regarding the detachable connection structure of the snap-fit ​​connector 42 and the mounting sleeve 3, please refer to the appendix. Figure 8 and 9As in Embodiment 2, a locking port 32 is provided on the mounting cylinder 3, specifically, the locking port 32 is provided along the radial direction 303 of the mounting cylinder 3; the snap-fit ​​member 42 includes a driving part 421, a snap-fit ​​part 422, and a rotating part 423. A mounting cavity 411 is provided in the docking member 41, and the rotating part 423 is rotatably mounted in the mounting cavity 411, and the rotation axis 4231 of the rotating part 423 is parallel to the axial direction 302 of the mounting cylinder 3. The driving part 421 is at least partially exposed from the docking member 41, and the driving part 421 is slidably mounted on the docking member 41, with the sliding direction of the driving part 421 being the radial direction 303 of the mounting cylinder 3; the snap-fit ​​part 422 is also slidably mounted on the docking member 41, with the sliding direction of the snap-fit ​​part 422 also being the radial direction 303 of the mounting cylinder 3. The rotating part 423 has an elongated design. The driving part 421 and the locking part 422 are movably connected to both ends of the rotating part 423. Specifically, each end of the rotating part 423 has an elongated hole, and each of the driving part 421 and the locking part 422 is provided with a slide. The two slides slide in the corresponding elongated holes, so that both the driving part 421 and the locking part 422 can slide relative to the rotating part 423 and can rotate relative to the sliding part 424. Driving the driving part 421 to slide can drive the rotating part 423 to rotate, thereby driving the locking part 422 to slide into or out of the locking port 32. When the locking part 422 is inserted into the locking port 32, if there is an external force to drive the second disc 2 out of the mounting cylinder 3, the locking part 422 will abut against the edge of the locking port 32 away from the first disc 1, thereby preventing the second disc 2 from continuing to detach from the mounting cylinder 3. The limiting component 4 also includes an elastic element 43, which is a compression spring. The elastic element 43 is located within the mounting cavity 411, with one end connected to the mating part 41 and the other end connected to the driving part 421 or the locking part 422. The elastic force of the elastic element 43 is used to drive the locking part 422 into the locking port 32. In this embodiment, the limiting component 4 can be unlocked by applying a linear force along the radial direction 303 of the mounting cylinder 3 to the driving part 421. Then, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to separate the second disc 2 from the mounting cylinder 3.

[0054] For details regarding the detachable connection structure of the snap-fit ​​connector 42 and the mounting sleeve 3, please refer to the appendix. Figure 10 and 11As in Embodiment 3, a locking port 32 is provided on the mounting cylinder 3, specifically, the locking port 32 is provided along the radial direction 303 of the mounting cylinder 3; the snap-fit ​​member 42 includes an integrally connected driving part 421, a snap-fit ​​part 422, and a sliding part 424, and a mounting cavity 411 is provided in the mating member 41, the sliding part 424 is slidably installed in the mounting cavity 411, and the sliding direction of the sliding part 424 is the radial direction 303 of the mounting cylinder 3. The driving part 421 is at least partially exposed from the mating member 41. By applying an external force to the driving part 421, the sliding part 424 slides along the radial direction 303 of the mounting cylinder 3, thereby driving the snap-fit ​​part 422 to enter or disengage from the locking port 32. When the snap-fit ​​part 422 extends into the locking port 32, if there is an external force to drive the second disc 2 to disengage from the mounting cylinder 3, the snap-fit ​​part 422 will abut against the edge of the locking port 32 away from the first disc 1, thereby preventing the second disc 2 from continuing to disengage from the mounting cylinder 3. The limiting component 4 also includes an elastic element 43, which is a compression spring. The elastic element 43 is located within the mounting cavity 411, and one end of the elastic element 43 is connected to the mating part 41, while the other end is connected to one of the driving part 421, the locking part 422, or the sliding part 424. The elastic force of the elastic element 43 is used to drive the locking part 422 into the locking port 32. In this embodiment, the limiting component 4 can be unlocked by applying a linear force along the radial direction 303 of the mounting cylinder 3 to the driving part 421. Then, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to separate the second disc 2 from the mounting cylinder 3.

[0055] For details regarding the detachable connection structure of the snap-fit ​​connector 42 and the mounting sleeve 3, please refer to the appendix. Figure 12 and 13As in Embodiment 4, a locking port 32 is provided on the mounting cylinder 3, specifically, the locking port 32 is provided along the radial direction 303 of the mounting cylinder 3; the snap-fit ​​member 42 includes a driving part 421 and a snap-fit ​​part 422, and a mounting cavity 411 is provided in the mating member 41. Both the driving part 421 and the snap-fit ​​part 422 are slidably mounted in the mounting cavity 411, and the sliding direction of the driving part 421 is parallel to the axial direction 302 of the mounting cylinder 3, while the sliding direction of the snap-fit ​​part 422 is the radial direction 303 of the mounting cylinder 3. The driving part 421 forms a first inclined slide 4211 in the mounting cavity 411, and the snap-fit ​​part 422 forms a second inclined slide 4221 in the mounting cavity 411. The first inclined slide 4211 and the second inclined slide 4221 are slidably connected. The drive unit 421 is at least partially exposed from the mating member 41 or from the side of the second disc 2 away from the first disc 1. By applying an external force to the drive unit 421, the drive unit 421 slides into the mounting cavity 411. The cooperation of the first inclined slide 4211 and the second inclined slide 4221 drives the locking part 422 to slide along the radial direction 303 of the mounting cylinder 3, thereby causing the locking part 422 to disengage from the locking port 32. The limiting assembly 4 also includes an elastic member 43, which is located in the mounting cavity 411. One end of the elastic member 43 is connected to the mating member 41, and the other end of the elastic member 43 is connected to the locking part 422. The elastic force of the elastic member 43 is used to drive the locking part 422 into the locking port 32. When the engaging part 422 extends into the locking port 32, if an external force attempts to disengage the second disc 2 from the mounting cylinder 3, the engaging part 422 will abut against the edge of the locking port 32 on the side away from the first disc 1, thereby preventing the second disc 2 from further disengaging from the mounting cylinder 3. In this embodiment, only a linear force along the axial direction 302 of the mounting cylinder 3 needs to be applied to the driving part 421 to unlock the limiting component 4. Then, a force in the opposite direction along the axial direction 302 of the mounting cylinder 3 is applied to the second disc 2 to separate the second disc 2 from the mounting cylinder 3.

[0056] In the above embodiments, the locking port 32 can be opened on the inner or outer surface of the mounting cylinder 3, and the elastic element 43 can be designed as a tension spring or a compression spring, the only difference being the change in the movement direction of the drive part 421. At the same time, in order to facilitate the installation of the snap-fit ​​part 42 and the elastic element 43 into the mounting cavity 411, the mating part 41 can be disassembled into several parts and then re-fixed with screws.

[0057] Regarding the structure of component 4, please refer to the appendix. Figure 14 and 16As in Embodiment 5, at least one locking port 32 is provided on the second disc body 2, and the locking port 32 is opened along the axial direction 302 of the mounting cylinder 3; the limiting component 4 includes at least two hooks 44, and each pair of hooks 44 corresponds to one locking port 32. The hooks 44 are fixedly installed on the mounting cylinder 3, and the hooks 44 also extend along the axial direction 302 of the mounting cylinder 3. When the second disc body 2 approaches the mounting cylinder 3 along the axial direction 302, the two hooks 44 pass through the locking port 32 respectively, and the two hooks 44 are respectively engaged on opposite sides of the locking port 32. When the hooks 44 are engaged on the locking port 32, the second disc body 2 and the mounting cylinder 3 are fixed circumferentially 301. When the user needs to release the connection between the locking component 42 and the second disc body 2, he / she can be disengaged from the locking port 32 by prying the two hooks 44. In this embodiment, the limiting component 4 can be unlocked by applying a linear force in opposite directions along the radial direction 303 of the mounting cylinder 3 to the two hooks 44 respectively. Then, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to the second disc 2 to separate the second disc 2 from the mounting cylinder 3.

[0058] Regarding the structure of component 4, please refer to the appendix. Figure 16 and 17 As in Embodiment Six, a receiving groove 34 and a locking port 32 connecting the receiving groove 34 and the outside are provided on the mounting cylinder 3. Specifically, the locking port 32 is provided along the radial direction 303 of the mounting cylinder 3. A mounting port 21 is provided on the second disc body 2. The limiting component 4 includes an integrally connected elastic connecting part 425, a driving part 421, and a snap-fit ​​part 422. The elastic connecting part 425 is U-shaped and accommodated in the receiving groove 34. The first end 4251 of the elastic connecting part 425 is connected to the second disc body 2, and the second end 4252 of the elastic connecting part 425 is sequentially connected to the snap-fit ​​part 422 and the driving part 421. The driving part 421 extends out from the mounting port 21. The second end 4252 of the elastic connecting part 425 can elastically deform relative to the first end 4251 of the elastic connecting part 425 in the radial direction 303 of the mounting cylinder 3. The edge of the mounting opening 21 away from the first end 4251 of the elastic connecting portion 425 is an abutment edge 211. The elastic force of the elastic connecting portion 425 is used to drive the driving portion 421 against the abutment edge 211 and the locking portion 422 to extend into the locking opening 32. When the locking portion 422 extends into the locking opening 32, the elastic connecting portion 425 is accommodated in the receiving groove 34. As shown in the attached diagram... Figure 16 As shown, the locking port 32 is located on the inner side of the mounting cylinder 3; as shown in the attached diagram. Figure 17 As shown, the locking port 32 is located on the outer surface, and the snap-fit ​​member 42 is positioned to correspond to the opening direction of the locking port 32. In these embodiments, the limiting component 4 can be unlocked simply by applying a linear force along the radial direction 303 of the mounting cylinder 3 to the driving part 421. Then, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to the second disc 2 to separate the second disc 2 from the mounting cylinder 3.

[0059] Regarding the structure of component 4, please refer to the appendix. Figure 18 and 19 As in Embodiment 7, a bolt hole 36 is provided on the mounting cylinder 3 along its axial direction 302. The limiting component includes a locking bolt 427, which passes through the second disc 2 and is screwed and fixed in the bolt hole 36. In this embodiment, after the locking bolt 427 disengages from the bolt hole 36, a linear force along the axial direction 302 of the mounting cylinder 3 is applied to the second disc 2, thereby separating the second disc 2 from the mounting cylinder 3.

[0060] In some embodiments, see Appendix Figure 3 and 4 A through groove 35 is provided on the outer wall of the mounting cylinder 3 along its axial direction 302. The through groove 35 is formed by the indentation of the side wall of the mounting cylinder 3, and the through groove 35 can also extend to the snap-fit ​​member 42. The through groove 35 connects the first bundling hole 102 and the second bundling hole 202. The through groove 35 provides space for bundling tools 2000 such as tape, cable ties, and Velcro to pass through, making it more convenient for users to bundle the consumable roll 1000.

[0061] In some embodiments, the snap-fit ​​member 42 is positioned corresponding to the through slot 35, and the snap-fit ​​member 42 at least partially passes through the second bundling hole 202 to be positioned on the side of the second tray 2 away from the first tray 1. The through slot 35 has a bottom surface 351 spaced apart from the consumable roll 1000. The snap-fit ​​member 42 is at least partially protruding from the bottom surface 351 and forms a guide structure 426. A guide surface 4261 is provided on the guide structure 426. The guide surface 4261 is connected to the bottom surface 351 of the through slot 35 and inclined outward from the second bundling hole 202. The guide structure 426 is, for example, attached to... Figure 4 The drive unit 421 shown is provided with a guide surface 4261, which allows the strapping tool 2000 to pass through the through slot 35 without being blocked by the protruding part of the snap-fit ​​member 42, and guides the strapping tool 2000 to the outside of the second strapping hole 202 using the guide surface.

[0062] Furthermore, to facilitate quick disconnection of the limiting component 4 from the mounting cylinder 3, in some embodiments, four first binding holes 102 are provided and distributed around the circumference of the first disc body 1. Four second binding holes 202 and four through slots 35 are also provided. The limiting component 4 includes two snap-fit ​​members 42 and two elastic members 43. The snap-fit ​​members 42 are arranged as described in the first embodiment, with the two snap-fit ​​members 42 symmetrically arranged around the center of the mounting cylinder 3, and each snap-fit ​​member 42 corresponding to one of the two through slots 35. Therefore, the user can quickly disconnect the snap-fit ​​members 42 from the mounting cylinder 3 by simultaneously pressing the driving part 421 of both snap-fit ​​members 42 with one hand, making it more convenient and easier to use.

[0063] Because different types of consumables may have different densities, the weight of consumables of the same volume will also vary. Traditional receptacles use weight scales to assess the remaining amount of consumables, which suffers from low accuracy. Therefore, in some embodiments, see the appendix. Figure 1 and 2 A viewing window 120 is provided on the first tray 1 and / or the second tray 2, through which the remaining thickness of the consumable roll 1000 can be observed. A length scale mark 1201 is provided next to the viewing window 120. In this embodiment, the length scale mark 1201 is used to express the remaining amount of consumables, making the remaining amount assessment more accurate. Alternatively, any one of the first binding holes 102 or the second binding hole 202 can be used as the viewing window 120, for example, as shown in the attached... Figure 18 As shown in the image.

[0064] Of course, the method of using weight scale to assess the remaining consumables can also be retained. Therefore, in some embodiments, a scale groove 121 is provided on the first disc 1 and / or the second disc 2, and the viewing window 120 and the length scale mark 1201 are both provided in the scale groove 121; as shown in the attached figure. Figure 2 As shown, the removable tray also includes a weight scale sticker 1202, which is affixed to the scale groove 121. The weight scale sticker 1202 is optional; if the user requires it, the weight scale sticker 1202 can be affixed to the side of the viewing window 120 in the scale groove 121.

[0065] In some embodiments, see Appendix Figure 2 , 4 5. At least one of the first disc body 1 and the second disc body 2 is provided with a rib structure 122, the rib structure 122 extending toward the mounting cylinder 3, and the rib structure 122 is used to abut against the consumable roll 1000. The rib structure 122 is generally triangular in design, and its end extending toward the mounting cylinder 3 can extend into the inner cylinder 1001 of the consumable roll 1000. Furthermore, a plurality of rib structures 122 are provided around the mounting cylinder 3 on both the first disc body 1 and the second disc body 2.

[0066] When the consumable roll 1000 is fitted onto the mounting cylinder 3 and the second disc 2 is connected to the mounting cylinder 3, the second disc 2 forces the inner cylinder 1001 of the consumable roll 1000 to abut against the rib structure 122, causing the inner cylinder 1001 to deform and thus locking the consumable roll 1000 in place, while preventing the consumable roll 1000 from rotating around the circumference 301 of the mounting cylinder 3. That is, when the second disc 2 is installed on the mounting cylinder 3 and the limiting component 4 is connected to the mounting cylinder 3, the positional relationships between the first disc 1, the second disc 2, the mounting cylinder 3, and the consumable cylinder are mutually locked. Using this structure, users do not need to specifically observe and calibrate the position of the consumable roll when installing it, making the installation process more streamlined.

[0067] In some embodiments, at least one of the first tray 1 and the second tray 2 is provided with a color card mounting slot 123. The color card mounting slot 123 is used to mount color cards, the colors of which correspond to the colors of the materials printed using consumables. The color cards are used to help users distinguish the colors of the consumables in the tray. Users can print color cards of the corresponding colors themselves using consumables and install them in the color card mounting slot 123. The color card mounting slot 123 can be designed with a snap-fit ​​structure for snapping the color cards in place. In addition, an RFID chip that records corresponding information can be embedded in the color card.

[0068] For unused consumable rolls 1000, to facilitate securing the consumable line 1002, in some embodiments, at least one of the first reel body 1 and the second reel body 2 is provided with a through-hole 125 for the consumable line 1002 to pass through. For example, see attached... Figure 1 The first disc body 1 shown has two wire locking holes 125. The consumable wire 1002 can be locked in position by passing through the two wire locking holes 125 in sequence.

[0069] To prevent damage to the consumable wire 1002 during wire clamping, in some other embodiments, at least one of the first reel 1 and the second reel 2 is provided with a wire clamping groove 124. The wire clamping groove 124 is located on the side of the first reel 1 facing the second reel 2 or on the side of the second reel 2 facing the first reel 1, and extends around the circumference 301 of the mounting cylinder 3. The width of the wire clamping groove 124 is slightly smaller than the diameter of the consumable wire 1002, so that the consumable wire 1002 can be clamped in the wire clamping groove 124 by interference fit, thereby locking the position of the consumable wire 1002 at the wire exit of the consumable roll 1000. It should be noted that the consumable wire 1002 clamping in the wire clamping groove 124 is not shown in the accompanying drawings.

[0070] Of course, in other embodiments, both the wire-locking hole 125 and the wire-locking groove 124 can be provided simultaneously, with the wire-locking hole 125 and the wire-locking groove 124 connected. Users can choose to use one of them.
