Description

Technical Field

[0001] This utility model relates to a 3D printer, and more particularly to a 3D printer heating material tank. Background Technology

[0002] Photopolymerization technology works based on the photopolymerization principle of liquid photosensitive resin. The liquid tank is filled with liquid photopolymerizable resin, and the laser beam can scan the liquid surface under the action of the deflection mirror. The liquid hit by the light spot is cured, and the liquid photosensitive resin is cured layer by layer. The cross section of each cured layer is obtained by layering the three-dimensional CAD model software of the part until the final 3D model is obtained.

[0003] A search revealed that patent CN219312034U discloses a heating material tank for a 3D printer, comprising a heating tank body. Two sets of electric actuators are located at the bottom of the heating tank body, and a movable plate is positioned between the output ends of the two sets of electric actuators. A heating plate and a disassembly / removal component for assembling and disassembling the heating plate are mounted on the movable plate. A stirring component is located at the bottom of the movable plate. The disassembly / removal component includes a fixed base mounted on the bottom of the heating plate and two sets of insert sleeves located at the bottom of the movable plate. This photopolymer 3D printer heating material tank heats the material through the heating plate, stirs the material through the stirring component, and simultaneously drives the electric actuators to uniformly heat the material within the heating tank body. In case of heating plate damage, the electric actuators push out the movable plate, pulling the sliding sleeves on both sides to disengage the inserts from the mounting posts, allowing for quick separation of the heating plate from the movable plate and easy removal for maintenance.

[0004] In the above device, the stirring component is located inside the heating tank body. When it is necessary to clean the inside of the heating tank body, the stirring component will be partially blocked, making it inconvenient to thoroughly clean the inside of the heating tank.

[0005] In addition, existing 3D printer heating troughs are generally installed on the printer by mounting holes and bolts. Since the position of the mounting holes on the printer is usually fixed, it is not possible to install heating troughs of different sizes according to usage needs. Summary of the Invention

[0006] The purpose of this utility model is to provide a heating material tank for a 3D printer, which has the characteristics of stirring materials through a stirring plate, allowing for unobstructed cleaning of the heating material tank, and adjusting the position of the heating material tank mounting holes to facilitate the installation of heating material tanks of different sizes as needed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heating tank for a 3D printer, comprising a heating tank body, wherein a stirring mechanism and an adjusting mechanism are respectively provided inside and below the heating tank body;

[0008] The stirring mechanism includes a vertical plate fixedly connected to the upper end of the heating tank body. An electric push rod is installed at the right end of the vertical plate. The output end of the electric push rod passes through the vertical plate and is fixedly connected to a support rod. A stirring plate is detachably connected to the outer wall of the support rod by bolts.

[0009] The adjustment mechanism includes an outer shell disposed below the heating tank body. The lower end of the outer shell has two symmetrically distributed sliding grooves. A slider is slidably connected inside the sliding grooves. The upper end of the slider has multiple evenly distributed V-shaped grooves. The lower end of the slider is fixedly connected to a mounting plate. The outer wall of the mounting plate has a through-hole. Fixing plates are fixedly connected to both the left and right sides of the outer shell. The upper end of the fixing plate is threadedly connected to a threaded rod. The lower end of the threaded rod is rotatably connected to a moving plate. The lower end of the moving plate is fixedly connected to a limit block.

[0010] Preferably, both the groove and the slider are in the shape of a cross.

[0011] Preferably, the outer wall of the stirring plate is provided with a plurality of evenly distributed through grooves.

[0012] Preferably, the outer wall of the movable plate abuts against the outer wall of the outer casing.

[0013] Preferably, the shape of the limiting block is adapted to the shape of the V-groove.

[0014] Preferably, a heating plate is installed on the inner wall of the outer shell, and the inner wall of the heating plate abuts against the outer wall of the heating tank body.

[0015] Preferably, the left and right ends of the outer shell are detachably connected to the heating tank body via screws.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] According to this utility model, when it is necessary to clean the inside of the heating tank body, the stirring plate can be moved to the side of the heating tank body or the bolts can be removed to remove the stirring plate for cleaning, so that the inside of the heating tank body can be unobstructed and the cleaning can be more thorough.

[0018] When installing the heating tank body onto the printer, pull the two mounting plates in opposite directions to align the mounting holes on the outer walls of the two mounting plates with the mounting holes on the printer. Then, rotate the threaded rod to drive the moving plate and the limiting block to move downwards, so that the limiting block is inserted into the V-shaped groove directly below to limit the outer shell. In this way, heating tank bodies of different sizes can be installed onto the printer.

[0019] In summary, the system achieves the goal of mixing materials using a stirring plate, ensuring unobstructed cleaning of the heating tank, and allowing for adjustment of the heating tank mounting holes to facilitate the installation of heating tanks of different sizes as needed.

[0044] In this embodiment, the left and right ends of the outer shell 1 are detachably connected to the heating tank body 2 by screws 18, which makes it easy to separate the outer shell 1 from the heating tank body 2, thereby making it easy to remove the heating plate 3 for maintenance.

[0045] Working principle: When using, first install the heating tank body 2 on the printer. The operation steps are as follows: pull the two mounting plates 8 to move in opposite directions so that the through holes 17 on the outer walls of the two mounting plates 8 are aligned with the mounting holes on the printer. Then rotate the threaded rod 12 to drive the moving plate 13 and the limiting block 14 to move downwards so that the limiting block 14 is inserted into the V-shaped groove 10 directly below to limit the outer shell 1. In this way, heating tank bodies 2 of different sizes can be installed on the printer.

[0046] Then, the material is placed inside the heating tank body 2. Then, the electric push rod 5 drives the support rod 6 and the stirring plate 7 to move back and forth inside the heating tank body 2, so that the material inside the heating tank body 2 can be stirred and heated evenly. When it is necessary to clean the inside of the heating tank body 2, the stirring plate 7 can be moved to the side of the heating tank body 2 or the stirring plate 7 can be removed for cleaning, so that the inside of the heating tank body 2 can be unobstructed and the cleaning can be more thorough.
