Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a consumable dust removal device. Background Technology

[0002] 3D printer filaments are the raw materials used to build solid models during the 3D printing process, and are mainly in the form of filaments. After being left unused for a long time, dust will accumulate on the filaments. If the dust enters the 3D printer with the filaments, it will mix with the molten filaments, causing uneven particles in the extruded material. This will result in spots, depressions, or bumps on the surface of the printed model, affecting the surface smoothness and accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a consumable dust removal device to solve the problem that dust accumulation on consumables in existing 3D printers affects printing accuracy and surface smoothness.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A consumable dust removal device includes a bracket mounted on a printer roller. A dust removal mechanism is provided at the end of the bracket. The dust removal mechanism includes a mounting plate fixed to the end of the bracket. Two brush rollers are rotatably connected inside the mounting plate. Two motors are fixed to the side of the mounting plate. The output shafts of the two motors movably pass through the mounting plate and are fixed to the side of the corresponding brush roller. Consumables pass through the bristles of the two brush rollers.

[0006] Furthermore, two sets of support components are fixed to the inner wall of the aforementioned mounting clamp. Each set of support components consists of two upper and lower support blocks. The two sets of support components are symmetrically arranged about the middle of the mounting clamp, and consumables pass through the space between the two support blocks.

[0007] Furthermore, the edges of the aforementioned support block are provided with curved chamfers.

[0008] Furthermore, a dust removal assembly is provided on the side of the aforementioned mounting clamp. The dust removal assembly includes two shaft tubes fixedly passing through the side of the mounting clamp. Two brush rollers are rotatably connected to the outer wall of the shaft tubes. Several through holes are opened on the inner wall of the brush rollers. All the through holes are arranged in a circumferential array about the center of the brush rollers. Square holes are opened at the top of the upper shaft tube and the bottom of the lower shaft tube. The square holes are connected to the through holes. The shaft tubes are connected to an external air pump through pipes.

[0009] Furthermore, the top and bottom of the aforementioned mounting clamp are equipped with dust-absorbing components, which include two square blocks disposed inside the mounting clamp, with adhesive layers applied to the opposite sides of the blocks.

[0010] Furthermore, the opposite sides of the two squares mentioned above are both curved.

[0011] Furthermore, magnetic plates are fixed to the opposite sides of both blocks, and the magnetic plates are magnetically attached to the mounting clamp.

[0012] Furthermore, handles are fixed to the opposite sides of both magnetic plates.

[0013] This utility model has the following beneficial effects:

[0014] This invention, by setting up a mounting plate, a motor, and brush rollers, allows the consumables to be positioned between the bristles of the two brush rollers during dust removal. The motor drives the brush rollers to rotate, and the rotating brush rollers clean the consumables, thus preventing dust from entering the printer along with the consumables and ensuring printing accuracy.

[0015] This invention incorporates a dust-cleaning component. After prolonged use, dust accumulates on the brush roller bristles. Activating the air pump delivers high-pressure airflow through pipes into the two shaft tubes. The airflow exits through the upper square hole of the upper shaft tube and then blows onto the brush roller bristles via a through-hole. During this process, the airflow can only exit through the through-hole located above the square hole. The brush roller continues to rotate, cleaning the entire roller and blowing dust upwards to prevent it from re-adhering to the consumables. Simultaneously, airflow exits through the lower square hole of the lower shaft tube and also blows onto the brush roller bristles via a through-hole. Again, the airflow can only exit through the through-hole located below the square hole. The brush roller continues to rotate, cleaning the entire roller and blowing dust downwards to prevent it from re-adhering to the consumables. By cleaning both brush rollers with airflow, the cleaning effect on the consumables is ensured, further improving printing accuracy.

[0016] This invention incorporates a dust-absorbing component, ensuring that both the airflow blown from above the upper brush roller and the airflow blown from below the lower brush roller are applied to the adhesive layer. The adhesive layer then absorbs the dust from the airflow, further preventing dust from re-adhering to the consumables.

[0017] This invention incorporates a support block to support the consumable material, ensuring its stable position between the two brush rollers and guaranteeing the effective dust removal of the brush rollers. Attached Figure Description

[0024] 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.

[0025] like Figures 1-5 As shown, an embodiment of this utility model provides a consumable dust removal device, including a bracket 1, which is mounted on a printer roller. A dust removal mechanism 2 is provided at the end of the bracket 1. The dust removal mechanism 2 includes a mounting clamp 3 fixed to the end of the bracket 1. Two brush rollers 5 are rotatably connected inside the mounting clamp 3. Two motors 4 are fixed to the side of the mounting clamp 3. The output shafts of the two motors 4 movably pass through the mounting clamp 3 and are fixed to the side of the corresponding brush roller 5. The consumable passes through the bristles of the two brush rollers 5.

[0026] The bracket 1 provides the mounting base for the entire device. By fixing it to the printer roller, it ensures that the dust removal mechanism 2 is precisely aligned with the path of the consumables entering the printer, guaranteeing that the consumables undergo a dust removal process before entering the printer. The mounting plate 3 serves as the mounting carrier for the brush roller 5 and the motor 4, stably assembling the various components into a whole and ensuring structural stability during the dust removal process. The motor 4 provides power to the brush roller 5, and its output shaft directly drives the brush roller 5 to rotate, causing the bristles to produce a continuous sweeping motion. The upper brush roller 5 cleans the upper half of the consumables, while the lower brush roller 5 cleans the lower half, achieving all-round removal of dust from the surface of the consumables. This prevents dust from entering the printer with the consumables and contaminating the precision components, thereby ensuring printing accuracy and the service life of the equipment. The symmetrical arrangement of the two brush rollers 5 can accommodate consumables of different thicknesses. The elastic contact of the bristles ensures the dust removal effect while avoiding excessive compression damage to the consumables. The motor 4 is electrically connected to an external power source via wires.

[0027] like Figure 5As shown in this embodiment, two sets of support components are fixed to the inner wall of the mounting clamp 3. Each set of support components consists of two upper and lower support blocks 14. The two sets of support components are symmetrically arranged about the middle of the mounting clamp 3. The consumables pass through the two support blocks 14. The edges of the support blocks 14 are provided with arc-shaped chamfers. The two sets of symmetrically distributed support blocks 14 form a guide channel. When cleaning, the consumables pass through the two upper and lower support blocks 14 of each set of support components, which can play a precise positioning and limiting role for the consumables, preventing the consumables from shifting left and right or shaking when the brush rollers 5 are sweeping, ensuring that the consumables are always in the optimal cleaning position of the two brush rollers 5, and ensuring a uniform cleaning effect.

[0028] like Figure 4 and Figure 5 As shown in this embodiment, a dust removal assembly 6 is provided on the side of the mounting clamp 3. The dust removal assembly 6 includes two shaft tubes 8 fixedly passing through the side of the mounting clamp 3. Two brush rollers 5 are rotatably connected to the outer wall of the shaft tubes 8. The inner wall of the brush rollers 5 has a plurality of through holes 7, which are arranged in a circumferential array about the center of the brush rollers 5. Square holes 9 are provided at the top of the upper shaft tube 8 and at the bottom of the lower shaft tube 8, and the square holes 9 are connected to the through holes 7. The shaft tubes 8 are connected to an external air pump through pipes. The shaft tubes 8 serve as airflow channels, introducing the high-pressure airflow generated by the external air pump into the interior of the brush rollers 5, while providing rotational support for the brush rollers 5 to ensure that the brush rollers 5 rotate and clean. Dust accumulation does not affect airflow. The through holes 7 in the circumferential array can evenly guide the airflow in the shaft tube 8 to the bristles of the brush roller 5. With the rotation of the brush roller 5, it can achieve all-round cleaning of the bristles of the entire brush roller 5, avoiding the reduction of dust removal effect due to excessive dust accumulation. The square hole 9 at the top of the upper shaft tube 8 allows the airflow to be blown out only from the through holes 7 in the upper half of the brush roller 5, blowing the dust upward away from the consumable area. The square hole 9 at the bottom of the lower shaft tube 8 allows the airflow to be blown out from the through holes 7 in the lower half of the brush roller 5, blowing the dust downward away. This can prevent the dust raised when cleaning the bristles from re-adhering to the consumable, ensuring that the brush roller 5 remains clean and continuously and efficiently removes dust from the surface of the consumable, further ensuring printing accuracy.

[0029] like Figure 5As shown in this embodiment, dust-collecting components 10 are provided at both the top and bottom of the mounting clamp 3. Each dust-collecting component 10 includes two square blocks 12 disposed inside the mounting clamp 3. Magnetic plates 11 are fixed to the opposite sides of each square block 12, and handles are fixed to the opposite sides of each magnetic plate 11. The magnetic plates 11 are magnetically attached to the mounting clamp 3. The opposite sides of the two square blocks 12 are both arc-shaped, and an adhesive layer 13 is applied to the opposite sides of each square block 12. The arc-shaped design allows the square blocks 12 to have greater contact with the dust airflow compared to a flat surface. The curved surface can more effectively capture dust particles at different angles, especially for dust that is dispersed in a diffuse manner, thus improving the adsorption efficiency of the adhesive layer 13. The magnetic connection between the magnetic plate 11 and the mounting clamp 3 enables the quick assembly and disassembly of the block 12. When the adhesive layer 13 adsorbs a lot of dust, causing the adhesiveness to decrease, the block 12 can be easily removed from the mounting clamp 3 for cleaning or replacement. The operation is convenient and requires no tools, greatly improving maintenance efficiency. The adhesive layer 13 can be adsorbed with glue or the like.

[0030] Ash removal process: When using this consumable ash removal device, first install the bracket 1 on the printer and ensure that the ash removal mechanism 2 is aligned with the path of the consumable entering the printer. When it is necessary to clean the consumable, pass the consumable between the two brush rollers 5. At this time, the consumable will be located between the upper and lower corresponding support blocks 14 of the two sets of support blocks 14 on the inner wall of the mounting plate 3. The arc-shaped chamfer of the edge of the support block 14 can avoid scratching the consumable, and at the same time play a guiding and limiting role for the consumable, ensuring that the consumable passes stably through the area of ​​the brush roller 5.

[0031] Start the two motors 4. The output shaft of the motors 4 drives the corresponding brush rollers 5 to rotate. The bristles of the upper brush roller 5 brush the upper part of the consumable, and the bristles of the lower brush roller 5 brush the lower part of the consumable. The rotating bristles remove the dust from the surface of the consumable, preventing dust from entering the printer with the consumable and ensuring printing accuracy.

[0032] When the brush roller 5 has been used for a long time and a lot of dust has accumulated on the bristles, the external air pump is started. The air pump sends high-pressure airflow into the two shaft tubes 8 through the pipe. For the upper shaft tube 8, the airflow is discharged from the square hole 9 at the top and then blown onto the bristles through the through holes 7 of the circumferential array on the inner wall of the brush roller 5. Since the square hole 9 is located at the top of the shaft tube 8, the airflow can only be blown out through the through holes 7 located above the square hole 9 on the inner wall of the brush roller 5. With the continuous rotation of the brush roller 5, the airflow can thoroughly clean the bristles of the entire brush roller 5 and blow the dust upward to prevent the dust from falling back onto the consumables. For the lower shaft tube 8, the airflow is discharged from the square hole 9 at the bottom and blown onto the bristles through the through holes 7 located below the square hole 9 on the inner wall of the brush roller 5. Similarly, the brush roller 5 completes a thorough cleaning during rotation and blows the dust downward to further prevent secondary contamination of the consumables by the dust and ensure that the brush roller 5 always maintains a good dust cleaning effect.

[0033] Dust blown upwards by the airflow will drift towards the dust-collecting component 10 at the top of the mounting plate 3, while dust blown downwards will drift towards the dust-collecting component 10 at the bottom. The square block 12 of the dust-collecting component 10 is magnetically attached to the mounting plate 3 via the magnetic plate 11. The arc-shaped design on the opposite side of the square block 12 can expand the dust contact range, and the adhesive layer 13 applied on the opposite side will absorb the dust in the airflow, completely preventing dust from re-adhering to the consumables or brush roller 5. When the adhesive layer 13 has absorbed a lot of dust, you can hold the handle on the opposite side of the magnetic plate 11 to remove the square block 12 from the mounting plate 3, replace or clean the adhesive layer 13, and then re-magnetically reinstall it to ensure that the dust-collecting component 10 continues to function.

[0034] 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.
