Description

Technical Field

[0001] This utility model relates to the field of material support platform technology, specifically a detachable material support platform for a 3D printer. Background Technology

[0002] In the 3D printing process, the material carrier is the component that holds the printed model. Currently, the material carrier of existing 3D printers is typically a structure fixedly mounted on the printer frame. After printing, a cooling and / or stress release buffer period is required before the printed model can be removed from the material carrier. During this period, the printer itself cannot perform the next printing job and must wait, which severely restricts printing efficiency. Utility Model Content

[0003] The present invention provides a detachable material support platform for a 3D printer, which solves the problem of low production efficiency caused by waiting for a period of time after printing before the model can be removed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A detachable material-bearing platform for a 3D printer includes a printer frame and a first lifting mechanism mounted on the printer frame. The first lifting mechanism has a mounting platform with two symmetrically arranged limiting guide frames. A linear displacement module is mounted on the mounting platform, and a second lifting mechanism is mounted on the linear displacement module. The second lifting mechanism has a pull hook, and a limiting mechanism is mounted on the mounting platform. The platform also includes a material-bearing platform with casters at its bottom. Guide grooves that mate with the limiting guide frames are formed on both sides of the material-bearing platform, and an inner groove that mates with the pull hook is formed at the bottom. A limiting groove that mates with the limiting mechanism is formed on the material-bearing platform. The first lifting mechanism is a common structure in all 3D printers, designed to move the material-bearing platform vertically. The linear displacement module can utilize existing technology, as long as it can move components such as the second lifting mechanism linearly, such as a conventional ball screw linear module. In use, the worker pushes the empty material receiving platform, moving it to the corresponding side of the mounting platform via the casters, aligning the guide grooves on both sides of the platform with the limiting guide frame. Then, the second lifting mechanism is activated to rise, pulling the hook into the inner groove. The linear displacement module then moves the second lifting mechanism, causing the hook to press against the inner wall of the groove on one side of the moving direction, thus moving the material receiving platform on the mounting platform until it reaches the printing station. Next, the limiting mechanism is activated, working with the limiting groove to fix the material receiving platform in place. Then, the second lifting mechanism descends, and the linear displacement module resets all components. After printing, the limiting mechanism disengages from the limiting groove, releasing the limiting position on the material receiving platform, removing it from the mounting platform. The aforementioned steps then allow for the loading of a new material receiving platform, enabling the model to be removed from the printer frame and the next model to be printed. This structure allows for quick replacement of the support platform, eliminating the need to wait for the model to cool down after printing. Continuous printing can be achieved simply by replacing the empty support platform, effectively reducing downtime and improving production efficiency. Simultaneously, the pre-positioning and subsequent movement of the guide frame and guide groove ensure the horizontal and vertical positioning accuracy of the support platform during installation, effectively preventing print quality issues caused by platform misalignment. Furthermore, casters are installed under the support platform, facilitating easy movement and relocation.

[0006] Furthermore, the pulling hook includes an L-shaped hook body disposed on the upper end of the second lifting mechanism, and a push rod disposed on the L-shaped hook body; a push groove corresponding to the front end of the inner groove is provided on the material receiving platform to cooperate with the push rod. In use, a portion of the L-shaped hook body enters the inner groove, and after displacement, it abuts against the inner wall of the inner groove to drive the material receiving platform to move. The push rod, when entering the push groove, will not push the material receiving platform upwards. During the movement driven by the linear displacement module, the outer end of the push rod will abut against the outer wall of the previous material receiving platform, thereby directly pushing the previous material receiving platform out of the mounting platform. This structure reduces the steps of manually removing the previous material receiving platform and also avoids collisions between the two replaced material receiving platforms.

[0007] Furthermore, the limiting guide frame includes a middle section frame disposed on both sides of the mounting platform, and inclined frames disposed at both ends of the middle section frame. With this structure, after the guide groove of the material receiving platform aligns with the inclined frames, it continues to move, and upon entering the middle section frame, it drives the material receiving platform to rise. This creates a gap between the casters below the material receiving frame and the mounting platform, thus avoiding the influence of the casters during subsequent movement of the material receiving platform and better enabling the limiting guide frame to cooperate with the guide groove for guiding displacement.

[0008] Furthermore, the limiting mechanism includes a first electric push rod disposed on the mounting platform, and the upper end of the first electric push rod is provided with a limiting rod that can be inserted into the limiting groove. With this structure, the first electric push rod can drive the limiting rod to rise and insert into the limiting groove, thereby achieving the limiting of the material receiving platform.

[0009] Furthermore, the second lifting mechanism includes a second electric push rod disposed on the movable seat of the linear displacement module. A connecting seat is provided at the upper end of the second electric push rod, and multiple telescopic sleeves are disposed between the connecting seat and the movable block of the linear displacement module. The L-shaped hook is detachably connected to the connecting seat. The first and second electric push rods can employ any existing technology capable of achieving the corresponding working principle of this application. The telescopic sleeves are of any length adapted to the second electric push rod, ensuring stable lifting and structural stability when the material support platform is moved. With this structure, the second electric push rod is vertically fixed to the movable seat of the linear displacement module, the connecting seat is fixed to the top of its piston rod, and the telescopic sleeves are symmetrically disposed on both sides of the second electric push rod, thereby ensuring the stability of the connecting seat during lifting and lowering, and the structural stability achieved by moving the material support platform.

[0010] Beneficial effects: This structure allows for quick replacement of the support platform, eliminating the need to wait for the model to cool down after printing. Continuous printing can be achieved simply by replacing the empty support platform, effectively reducing equipment downtime and improving production efficiency. Simultaneously, the pre-positioning and subsequent movement of the guide frame and guide groove ensure the horizontal and vertical positioning accuracy of the support platform during installation, effectively preventing print quality issues caused by platform misalignment. Furthermore, the inclusion of casters beneath the support platform facilitates easy movement and convenient transfer. Attached Figure Description
