Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printer technology, and specifically to a consumable box for preventing the replacement of consumables. Background Technology
[0002] 3D printing, also known as additive manufacturing or rapid prototyping, is a technology that uses digital model files as a basis and employs bondable materials such as powdered metals, plastics, and linear filaments to construct objects layer by layer. These bondable materials are typically housed in corresponding filament cartridges. The compatibility of 3D printer filaments is a key factor in ensuring smooth printing; different brands of 3D printers have different requirements for filaments. In some specific 3D printer models, the filament cartridge needs to be paired with the printer. For example, the Da Vinci series 3D printers use EEPROM in their filament cartridges, which can be seen as a form of encoding used for matching and identification with the printer.
[0003] Existing 3D printer liner cartridges typically require opening and replacing the liner with a new one after it's used up, allowing for continued use. However, different printer models and printed products require different liner types; not all liner types are universal. Furthermore, replacing some liner types necessitates resetting the printer based on the liner's properties. To prevent unauthorized liner replacement and to avoid incompatible liner types affecting the printer and print quality, this paper proposes a liner cartridge designed to prevent liner replacement. Utility Model Content
[0004] The purpose of this invention is to provide a consumable box that prevents the replacement of consumables, so as to solve the problems pointed out in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A consumable box for preventing the replacement of consumables, comprising:
[0007] The box body includes an upper shell and a lower shell symmetrically arranged below the upper shell and snapped into the upper shell. An outlet is provided on one side of the upper shell / lower shell.
[0008] The consumable wheel is rotatably mounted between the upper and lower housings and is used to install consumables. The consumables on the consumable wheel pass through the outlet.
[0009] And an identification mechanism, which is bonded between one inner wall of the upper housing and one inner wall of the lower housing.
[0010] Furthermore, corresponding and interconnected mounting grooves are respectively provided on one inner wall of the upper shell and one inner wall of the lower shell;
[0011] The identification mechanism includes a coil fixing plate, a coil, and an NFC chip. The coil fixing plate is installed between two mounting slots and is bonded to the bottom wall of the mounting slots. The coil fixing plate has an annular groove for installing the coil on the side away from the mounting slots. The NFC chip is installed on the coil fixing plate and is electrically connected to the coil through a wire. The coil fixing plate has a long through slot along its length that corresponds to the connection between the upper and lower housings, and the length of the through slot is less than the length of the coil fixing plate.
[0012] Furthermore, the aforementioned long through slot coincides with the centerline of the coil fixing plate in the length direction.
[0013] Furthermore, the inner walls of the upper and lower housings are symmetrically provided with limiting plates for limiting the coil fixing plate.
[0014] Furthermore, the mounting cavity formed between the mounting groove on the upper housing and the mounting groove on the lower housing matches the size of the coil fixing plate.
[0015] Furthermore, the coil fixing plate has an opening in the middle that communicates with the long through groove, and the opening is located inside the annular groove.
[0016] Furthermore, the inner wall of the upper shell is provided with a number of fixing blocks at intervals, and the fixing blocks extend along the direction of the lower shell. A first slot is provided on the side of the fixing block near the lower shell.
[0017] The inner wall of the lower housing is provided with a second slot that matches the fixing block, and the bottom wall of the second slot is provided with a locking block that engages with the first slot.
[0018] Furthermore, the outer edge of the upper shell is provided with an annular step, and the outer edge of the lower shell is provided with an annular protrusion that matches the annular step.
[0019] This utility model has the following beneficial effects:
[0020] 1. This utility model relates to a consumable box designed to prevent consumable replacement. The consumables are mounted on consumable wheels. Adhesive is first applied to the side wall of the identification mechanism, which is then bonded to one inner wall of the upper / lower housing. The lower / upper housing is then installed on top of the upper / lower housing, and the upper and lower housings are locked together. At this point, the identification mechanism is bonded between the inner walls of the upper and lower housings. The identification mechanism communicates with the external 3D printing equipment for pairing the consumable box. When the consumables are used up, if the user wants to disassemble the consumable box and replace them with new consumables, pulling the upper and lower housings to the sides will destroy the bonded identification mechanism. Therefore, even after replacing with new consumables, the device cannot establish a connection with the 3D printing equipment, rendering the consumable box unusable. This effectively prevents users from privately replacing consumables and avoids consumable incompatibility affecting the printer, thus preventing impact on the printing quality.
[0021] 2. The consumable box of this utility model for preventing replacement of consumables is designed with a fixing block, a first slot, a second slot, and a locking block, which makes the upper shell and the lower shell double-locked, making the connection between the upper shell and the lower shell more stable and less likely to loosen.
[0022] 3. The consumable box of this utility model for preventing the replacement of consumables has an annular step on the outer edge of the upper shell and an annular protrusion on the outer edge of the lower shell that matches the annular step, which facilitates quick alignment between the upper and lower shells and avoids misalignment.

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0031] like Figures 1 to 6 As shown, an embodiment of this utility model provides a consumable box to prevent the replacement of consumables, comprising:
[0032] Box 1 includes an upper shell 11 and a lower shell 12 symmetrically arranged below the upper shell 11 and snapped into the upper shell 11. An outlet 13 is provided on one side of the upper shell 11 / lower shell 12. In this embodiment, the outlet 13 is provided on one side of the upper shell 11, and no specific limitation is made here.
[0033] Specifically, the inner wall of the upper housing 11 is provided with a plurality of fixing blocks 111 at intervals, and the fixing blocks 111 extend along the direction of the lower housing 12. A first slot 112 is provided on the side of the fixing block 111 near the lower housing 12. The inner wall of the lower housing 12 is provided with a second slot 121 that matches the fixing blocks 111. Multiple second slots 121 are provided, each corresponding to one of the fixing blocks 111. The bottom wall of the second slot 121 is provided with a locking block 122 that engages with the first slot 112. Through the engagement of the fixing blocks 111 with the second slots 121 and the engagement of the first slots 112 with the locking blocks 122, the double engagement makes the connection between the upper housing 11 and the lower housing 12 more stable and less prone to loosening.
[0034] Consumable wheel 2 is rotatably mounted between upper housing 11 and lower housing 12 and is used to install consumables. The consumables on consumable wheel 2 pass through outlet 13. One end of consumable wheel 2 is fixedly connected to a rotating wheel, and the other end of consumable wheel 2 is fixedly connected to a ratchet. The inner wall of upper housing 11 is provided with a rotating shaft 1 that cooperates with the ratchet, and the inner wall of lower housing 12 is provided with a rotating shaft 2 that cooperates with the rotating wheel, thereby realizing the rotation of consumable wheel 2.
[0035] The system includes an identification mechanism 3, which is bonded between one inner wall of the upper housing 11 and one inner wall of the lower housing 12. The identification mechanism 3 communicates with the external 3D printing equipment. When the consumables are used up, if the user wants to disassemble the consumable box and replace it with new consumables, pulling the upper housing 11 and the lower housing 12 to the sides will destroy the bonded identification mechanism 3. Therefore, even if new consumables are replaced, the system will not be able to establish a connection with the 3D printing equipment, resulting in the consumable box becoming unusable. This effectively prevents users from replacing consumables privately and avoids the impact of incompatible consumables on the printer and printing results.
[0036] Specifically, one inner wall of the upper housing 11 and one inner wall of the lower housing 12 are respectively provided with corresponding and communicating mounting grooves 14; the identification mechanism 3 includes a coil fixing plate 31, a coil 32, and an NFC chip 33; the coil fixing plate 31 is installed between the two mounting grooves 14 and is bonded to the bottom wall of the mounting groove 14, and the mounting cavity formed between the mounting grooves 14 on the upper housing 11 and the mounting grooves 14 on the lower housing 12 matches the size of the coil fixing plate 31; an annular groove 34 for installing the coil 32 is provided on the side of the coil fixing plate 31 away from the mounting groove 14, the NFC chip 33 is installed on the coil fixing plate 31 and is electrically connected to the coil 32 through a wire, and the NFC chip 33 is installed on the side of the coil fixing plate 31 away from the mounting groove 14; the coil fixing plate 31 is provided with a long through groove 35 along its length direction corresponding to the connection between the upper housing 11 and the lower housing 12, and the length of the long through groove 35 is less than the length of the coil fixing plate 31. In this embodiment, the long through groove 35 coincides with the centerline of the coil fixing plate 31 in the length direction.
[0037] In order to limit the coil fixing plate 31, the inner sidewalls of the upper housing 11 and the lower housing 12 are respectively provided with limiting plates 15 for limiting the coil fixing plate 31.
[0038] The coil fixing plate 31 has an opening 36 in the middle that communicates with the long through groove 35, and the opening 36 is located inside the annular groove 34. The opening 36 makes it easy to break the coil fixing plate 31 when disassembling the upper housing 11 and the lower housing 12, thereby making it easy to break the coil 32 and disconnect the NFC chip 33 from the external 3D printing equipment.
[0039] In order to facilitate quick alignment between the upper housing 11 and the lower housing 12 and avoid misalignment, an annular step 113 is provided on the outer edge of the upper housing 11, and an annular protrusion 123 matching the annular step 113 is provided on the outer edge of the lower housing 12.
[0040] When using the consumable box of this utility model to prevent the replacement of consumables, the consumables are installed on the consumable wheel 2. First, adhesive is applied to one side of the coil fixing plate 31, and then it is bonded to the bottom wall of the mounting groove 14 on the upper housing 11. Finally, the lower housing 12 is installed on the upper housing 11. With the cooperation of the annular protrusion 123 and the annular step 113, the upper housing 11 and the lower housing 12 can be quickly aligned and snapped together. At this time, the coil fixing plate 31 is inserted into the mounting groove 14 on the lower housing 12, and the adhesive on the side wall of the coil fixing plate 31 is bonded to the bottom wall of the mounting groove 14 on the lower housing 12, so that the identification mechanism 3 is fixed between one side inner wall of the upper housing 11 and one side inner wall of the lower housing 12. The identification mechanism 3 communicates with the external 3D printing equipment for the pairing connection of the consumable box.
[0041] When the consumables are used up, if the user wants to disassemble the consumable box and replace them with new consumables, pulling the upper housing 11 and the lower housing 12 to the sides will cause the coil fixing plate 31 to deform and break along both sides of the long through groove 35 under the pulling force on both sides. The coil 32 in the annular groove 34 will be pulled off, thus damaging the identification mechanism 3. Therefore, even if new consumables are replaced, it will not be able to establish a connection with the 3D printing equipment, resulting in the consumable box being scrapped. This can effectively prevent users from replacing consumables privately and avoid the situation where incompatible consumables affect the printer, thus avoiding affecting the printing effect of the product.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
