Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing consumables technology, and more specifically, to a dust removal device for 3D printing consumables. Background Technology
[0002] 3D printing is a manufacturing technology that creates objects by depositing materials layer by layer. 3D printers use appropriate materials, such as plastics, metals, or ceramics, and gradually build up the final object shape by heating or curing the material layer by layer. Desktop 3D printers typically use PLA and ABS as filaments. One end of the filament is wound on a spool, and the other end is inserted into the feeding mechanism for extrusion from the print head. During 3D printing, the filament is prone to dust accumulation, which can affect the quality of the print. Therefore, dust removal is necessary.
[0003] Based on the above, the inventors have discovered that existing dust removal devices mainly clean consumables using brushes. However, the sides of the consumables are curved, and the brushes cannot fully adhere to the surface of the consumables, resulting in dead corners and affecting the dust removal effect. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a dust removal device for 3D printing consumables, aiming to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dust removal device for 3D printing consumables. This solution is equipped with a self-rotating dust removal component in conjunction with a revolution structure, which can perform comprehensive dust removal on the outside of the consumable, reduce dust removal dead corners, and improve the dust removal effect. In addition, an adjustment component is provided to adjust the spacing of the dust removal component to adapt to consumables of different specifications, thereby improving the applicability of the dust removal device.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A dust removal device for 3D printing consumables includes a mounting plate. One end of the mounting plate is provided with a feed cylinder, and the other end of the mounting plate is fixedly connected to a drive motor. The feed cylinder is provided with two pairs of rotating rollers. A dust removal groove is opened in the middle of the rotating rollers, and an adjustment mechanism is provided on the outside of the rotating rollers. A set of toothed blocks is fixedly connected to the center of the outside of the feed cylinder, and a limit ring is fixedly connected to the bottom of the feed cylinder.
[0009] The adjusting mechanism includes a threaded rod, with a movable ring fixedly connected to one inner end of the threaded rod, and a limit frame movably connected to the outer side of the movable ring. A pair of guide rods are fixedly connected to one side of the limit frame.
[0010] Furthermore, a geared disc is fixedly connected to the output end of the drive motor, and the geared disc meshes with the gear block.
[0011] Furthermore, the two pairs of rotating rollers are staggered, and the two rotating rollers located at the same horizontal position are symmetrically arranged, and a cleaning cloth is sleeved on the outside of the cleaning trough.
[0012] Furthermore, the limiting ring is located inside the mounting plate, and the limiting ring is movably connected to the mounting plate.
[0013] Furthermore, the threaded rod passes through the feed cylinder and is threadedly connected to the feed cylinder, with a torque fixedly connected to one end of the threaded rod on the outer side.
[0014] Furthermore, the rotating roller is located inside the limiting frame, and the rotating roller is movably connected to the limiting frame.
[0015] Furthermore, the guide rod passes through the feed cylinder and is slidably connected to the feed cylinder.
[0016] 3. Beneficial Effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) This solution uses friction between the consumable and the cleaning trough to drive the rotating roller to rotate and clean the consumable. At the same time, the drive motor is started to drive the toothed disc to rotate. The toothed disc and the toothed block drive the material cylinder to rotate, so that the rotating roller rotates in the vertical direction and the ash removal angle is adjusted. Compared with the existing technology, the self-rotating ash removal component is set up in conjunction with the revolution structure, which can carry out comprehensive ash removal on the outside of the consumable, reduce the dead angle of ash removal, and improve the ash removal effect.
[0019] (2) By setting an adjustment mechanism, the screw rod is rotated by the rotary knob. The rotation of the screw rod, in conjunction with the movable ring, drives the limit frame to move. The guide rod plays a limiting role, ensuring the stability of the movement of the limit frame, so that the outer side of the consumable is in contact with the ash removal groove. Compared with the prior art, the setting of the adjustment component can adjust the spacing of the ash removal component to adapt to consumables of different specifications and improve the applicability of the ash removal device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1-4 A dust removal device for 3D printing consumables includes a mounting plate 1, a feed cylinder 2 extending through one end of the mounting plate 1, and a drive motor 3 fixedly connected to the other end of the mounting plate 1. Two pairs of rotating rollers 4 are arranged inside the feed cylinder 2. A dust removal groove 5 is opened in the middle of the rotating rollers 4, and an adjustment mechanism 6 is arranged on the outer side of the rotating rollers 4. A set of toothed blocks 8 is fixedly connected to the center of the outer side of the feed cylinder 2, and a limit ring 9 is fixedly connected to the bottom of the feed cylinder 2.
[0028] The adjustment mechanism 6 includes a threaded rod 10, with a movable ring 11 fixedly connected to the inner end of the threaded rod 10. A limit frame 12 is movably connected to the outer side of the movable ring 11. A pair of guide rods 13 are fixedly connected to one side of the limit frame 12. The adjustment mechanism 6 is provided to adjust the dust removal spacing to adapt to consumables of different specifications.
[0029] See Figure 1 The output end of the drive motor 3 is fixedly connected to a toothed disc 7, which meshes with a toothed block 8. When the drive motor 3 is started, the toothed disc 7 rotates, and the feed cylinder 2 rotates through the toothed disc 7 and the toothed block 8.
[0030] See Figure 2 Two pairs of rotating rollers 4 are staggered and the two rotating rollers 4 located at the same horizontal position are symmetrically arranged. A cleaning cloth is sleeved on the outside of the cleaning trough 5. The surface of the consumables is cleaned from different directions by the two pairs of staggered rotating rollers 4.
[0031] See Figure 3The limiting ring 9 is located inside the mounting plate 1 and is movably connected to the mounting plate 1. The limiting ring 9 plays a limiting role to ensure the rotational stability of the feed cylinder 2.
[0032] See Figure 2 The threaded rod 10 passes through the feed cylinder 2 and is threadedly connected to the feed cylinder 2. A knob is fixedly connected to the outer end of the threaded rod 10. Rotating the knob causes the threaded rod 10 to rotate. The rotation of the threaded rod 10, in conjunction with the movable ring 11, causes the limit frame 12 to move.
[0033] See Figure 4 The rotating roller 4 is located inside the limiting frame 12 and is movably connected to the limiting frame 12. The consumable material is passed through two pairs of rotating rollers 4 in sequence, so that the outer side of the consumable material is in contact with the dust removal groove 5. During the 3D printing process, as the consumable material moves, it rubs against the dust removal groove 5, causing the rotating roller 4 to rotate.
[0034] See Figure 4 The guide rod 13 passes through the feed cylinder 2 and is slidably connected to the feed cylinder 2, thereby ensuring the movement stability of the limit frame 12.
[0035] In use: The filament is passed through the feed cylinder 2, so that the rotating roller 4 is located outside the filament. The screw rod 10 is rotated by the torque. The rotation of the screw rod 10, in conjunction with the movable ring 11, drives the limit frame 12 to move. The guide rod 13 acts as a limit to ensure the stability of the movement of the limit frame 12, so that the outside of the filament is in contact with the dust removal groove 5. During the 3D printing process, as the filament moves, it rubs against the dust removal groove 5, which drives the rotating roller 4 to rotate and clean the filament. At the same time, the drive motor 3 is started to drive the toothed disc 7 to rotate. Through the toothed disc 7 and the toothed block 8, the feed cylinder 2 is driven to rotate, so that the rotating roller 4 rotates in the vertical direction, reducing the dust removal dead angle and improving the dust removal effect.
