Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, specifically a 3D printer tray mounting mechanism. Background Technology

[0002] In the 3D printing process, the filament tray, as the carrier of consumables (such as PLA and ABS filaments), needs to be stably fixed to the printer by a mounting mechanism to ensure smooth filament feeding. Current 3D printer filament tray mounting mechanisms typically use a "mounting post and filament tray center hole" method. That is, the filament tray is directly fitted onto the mounting post on the printer frame through its center hole. The interference fit or transition fit between the mounting post and the center hole prevents the filament tray from wobbling. Simultaneously, the filament tray is also equipped with a rotatable inner rotating block to facilitate its rotation on the mounting post and prevent pulling on the consumables.

[0003] However, in practical applications, the central hole diameter of 3D printing trays of different specifications and brands varies, such as the common diameters of 38mm, 50mm, and 60mm. When changing trays with different hole diameters, operators need to disassemble and replace the mounting posts that are compatible with the central hole of the new tray. Some mounting mechanisms even need to be completely disassembled and replaced, which is cumbersome and time-consuming. Utility Model Content

[0004] The present invention provides a 3D printer tray mounting mechanism to solve the problem that existing mounting mechanisms require frequent disassembly and assembly to adapt to trays with different apertures.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A 3D printer tray mounting mechanism includes a printer frame, a mounting bracket on the side of the printer frame, a lifting mechanism on the mounting bracket, a lifting platform on the lifting mechanism, a fixed frame on the lifting platform, a first adjusting screw rotatably connected to the fixed frame, a displacement screw threaded onto the first adjusting screw, a fixed block on the fixed frame, and multiple connecting rod adjusting components circumferentially equidistantly arranged on the displacement screw and the fixed block. Each connecting rod adjusting component has a tray inner abutment, and tray limiting blocks are provided at both ends of the tray inner abutment. Some existing trays have a rotatable rotating base at their inner end, allowing the tray inner abutment to directly abut against the inner hole of the rotating base; alternatively, a bullseye ball bearing can be provided on the tray inner abutment to support the inner hole of a tray without a rotating base. Further details are omitted here; this application primarily addresses radial adjustment for different hole diameters. In use, the height of the tray after installation can be adjusted via a lifting mechanism. Then, when installing trays with different aperture sizes, the operator rotates the first adjusting screw. Because a connecting rod adjustment assembly is provided between the displacement screw block and the fixed block, the displacement screw block cannot rotate circumferentially with the first adjusting screw; it can only move axially. When the displacement screw block moves in different directions, it causes the inner abutment block of the tray to expand radially outward or contract radially, thus adapting to trays with larger or smaller apertures. Using this structure, by setting up a mounting bracket and lifting mechanism on the side of the printer frame, the vertical height of the tray can be flexibly adjusted according to different printing needs. Simultaneously, the cooperation between the first adjusting screw and the displacement screw block, and the multiple connecting rod adjustment assemblies between the displacement screw block and the fixed block, allow for accurate adjustment according to the actual aperture requirements of the tray. This supports trays of different sizes, prevents tray displacement or shaking during use, ensures a stable supply of printing consumables, and guarantees print quality.

[0007] Furthermore, the linkage adjustment assembly includes a first connecting rod rotatably connected to the displacement screw block, a second connecting rod rotatably connected to the fixed block, and an intermediate connecting rod rotatably connected at both ends to the first and second connecting rods respectively; the inner abutment block of the material tray is disposed on the intermediate connecting rod. With this structure, when the displacement screw block moves closer to the fixed block, the angle between the first and second connecting rods decreases, causing the intermediate connecting rod to drive the inner abutment block of the material tray to expand radially outward, adapting to material trays with larger apertures; when the displacement screw block moves away from the fixed block, the angle between the first and second connecting rods increases, causing the inner abutment block of the material tray to contract radially inward, adapting to material trays with smaller apertures. This adjustment method is simple and reliable in structure, accurately realizing the radial adjustment action of the inner abutment block of the material tray, ensuring stable support for material trays with different apertures.

[0008] Furthermore, the inner abutment block of the material tray includes an intermediate bracket mounted on the intermediate connecting rod, an adjusting guide rod mounted on the intermediate bracket, a second adjusting screw rotatably connected to the intermediate bracket, and an outer bracket corresponding to the outer side of the intermediate bracket and symmetrically slidably connected to the adjusting guide rod. The outer brackets are threadedly connected to the second adjusting screw. The threaded connections of the two outer brackets are in opposite directions, thus enabling movement towards or away from each other. With this structure, by rotating the second adjusting screw, the two outer brackets move synchronously closer or further away along the thickness direction of the material tray under the limiting and guiding action of the adjusting guide rod, thereby changing the distance between the two material tray limiting blocks. This achieves limiting of material trays of different thicknesses, effectively preventing axial movement or detachment of the material tray during use, improving the stability and reliability of the material tray installation, and expanding the applicability of the installation mechanism.

[0009] Furthermore, it includes at least three of the aforementioned linkage adjustment assemblies. The three linkage adjustment assemblies are equidistant from each other. With this structure, multiple evenly distributed linkage adjustment assemblies can apply supporting forces to the inner abutment of the material tray from multiple directions, ensuring balanced force distribution on the material tray in all directions.

[0010] Furthermore, both the first and second adjusting screws are equipped with adjusting handles. This structure allows operators to easily rotate the first and second adjusting screws.

[0011] Furthermore, the lifting mechanism includes a lifting guide rod mounted on the mounting frame and a lifting screw rotatably connected to the mounting frame. One end of the lifting screw passes through the mounting frame and is fixedly connected to the output end of a lifting motor. The lifting motor is mounted on the mounting frame via a motor mount. The lifting platform is slidably connected to the lifting guide rod and threadedly connected to the lifting screw. The lifting motor can be any type of servo motor from the prior art, as long as it can drive the lifting screw to rotate. With this structure, after the lifting motor starts, the lifting platform moves vertically up and down under the drive of the lifting screw and the guiding action of the lifting guide rod, realizing vertical position adjustment of the material tray. This adapts to the requirements of wire conveying at different heights and facilitates the operator's loading and unloading of the material tray, improving ease of use.

[0012] Beneficial effects: By setting up mounting brackets and lifting mechanisms on the side of the printer frame, the vertical height of the material tray can be flexibly adjusted according to different printing needs. At the same time, the cooperation between the first adjusting screw and the displacement screw block, as well as the multiple linkage adjustment components set between the displacement screw block and the fixed block, can accurately adjust according to the actual aperture requirements of the material tray, thereby supporting material trays of different sizes, preventing the material tray from shifting or shaking during use, ensuring a stable supply of printing consumables, and guaranteeing print quality.

[0017] The following will provide a more detailed description of the technical solution of a 3D printer tray mounting mechanism according to the present invention, with reference to the embodiments.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, a 3D printer tray mounting mechanism of this embodiment includes a printer frame 1, a mounting frame 2 is provided on the side of the printer frame 1, a lifting mechanism 3 is provided on the mounting frame 2, a lifting platform 4 is provided on the lifting mechanism 3, a fixed frame 5 is provided on the lifting platform 4, a first adjusting screw 6 is rotatably connected to the fixed frame 5, a displacement screw block 7 is threadedly connected to the first adjusting screw 6, a fixed block 8 is provided on the fixed frame 5, and a plurality of connecting rod adjusting components 9 are circumferentially equidistant from the displacement screw block 7 and the fixed block 8. Each connecting rod adjusting component 9 is provided with a tray inner abutment block 10, and tray limiting blocks 11 are provided at both ends of the tray inner abutment block 10. Some existing material trays have a rotatable rotating base at the inner end, so that the inner abutment block 10 of the material tray directly abuts against the inner hole of the rotating base; alternatively, a bullseye ball bearing can be set on the inner abutment block 10 of the material tray to support the inner hole of the material tray without a rotating base. Details are omitted here, but this application mainly focuses on radial adjustment of different hole diameters. The connecting rod adjustment assembly 9 includes a first connecting rod 901 rotatably connected to the displacement screw block 7, a second connecting rod 902 rotatably connected to the fixed block 8, and an intermediate connecting rod 903 with its two ends rotatably connected to the first connecting rod 901 and the second connecting rod 902 respectively; the inner abutment block 10 of the material tray is disposed on the intermediate connecting rod 903. The inner abutment block 10 of the material tray includes an intermediate support 1001 disposed on the intermediate connecting rod 903, an adjusting guide rod 1002 disposed on the intermediate support 1001, a second adjusting screw 1003 rotatably connected to the intermediate support 1001, and an outer support 1004 corresponding to the outer side of the intermediate support 1001 and symmetrically slidably connected to the adjusting guide rod 1002. The outer support 1004 is threadedly connected to the second adjusting screw 1003. It includes at least three connecting rod adjusting assemblies 9. The three connecting rod adjusting assemblies 9 are equidistant from each other. Both the first adjusting screw 6 and the second adjusting screw 1003 are provided with adjusting handles 12. The lifting mechanism 3 includes a lifting guide rod 301 mounted on the mounting frame 2 and a lifting screw 302 rotatably connected to the mounting frame 2. One end of the lifting screw 302 passes through the mounting frame 2 and is fixedly connected to the output end of a lifting motor 303. The lifting motor 303 is mounted on the mounting frame 2 via a motor mount. The lifting platform 4 is slidably connected to the lifting guide rod 301 and threadedly connected to the lifting screw 302.In use, the height of the tray after installation can be adjusted via the lifting mechanism 3. Then, when installing trays with different apertures, the operator rotates the first adjusting screw 6. Because a connecting rod adjusting assembly 9 is provided between the displacement screw block 7 and the fixed block 8, the displacement screw block 7 cannot rotate circumferentially with the first adjusting screw 6; it can only move axially along the first adjusting screw 6. When the displacement screw block 7 moves in different directions, it will cause the inner abutment block 10 of the tray to expand radially outward or contract radially, thus adapting to trays with larger or smaller apertures. Using this structure, by setting the mounting bracket 2 and lifting mechanism 3 on the side of the printer frame 1, the vertical height of the tray can be flexibly adjusted according to different printing needs. Simultaneously, the cooperation between the first adjusting screw 6 and the displacement screw block 7, and the multiple connecting rod adjusting assemblies 9 between the displacement screw block 7 and the fixed block 8, allows for accurate adjustment according to the actual aperture requirements of the tray, thereby supporting trays of different sizes, preventing tray displacement or shaking during use, ensuring a stable supply of printing consumables, and guaranteeing print quality.

The power supply is also common knowledge or conventional technology in the field. Therefore, this utility model will not explain the control method and circuit connection in detail.
