Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a cleaning and brushing device for 3D printed parts. Background Technology

[0002] There are several reasons for using cleaning brushes on 3D printed parts. First, they remove support material, especially in complex areas, allowing for precise cleaning and preventing damage. Second, they improve surface quality by removing excess particles and imperfections, increasing precision and ensuring the parts better meet design requirements. Third, they prepare for subsequent processing, ensuring better adhesion of finishing materials and preventing impurities from affecting the final result. Finally, they enhance overall quality and aesthetics, allowing for finer detail processing, clearer textures and lines, and a more professional and high-quality appearance, resulting in a better impression for both display and practical application.

[0003] Currently, cleaning 3D printed parts mainly involves manual operation using spray guns and brushes. However, this method is relatively inefficient and requires a significant amount of time and manpower. Furthermore, cleaning is extremely difficult when there are holes or dents in the parts, making them difficult to thoroughly clean. In addition, fine particles swept off easily fall deep into the holes and are difficult to remove, which not only affects the cleanliness of the parts but may also cause potential problems during subsequent use, reducing the quality and performance of the parts. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a cleaning and brushing device for 3D printed parts that can perform large-scale cleaning and brushing work, facilitates the timely removal of fine particles, and avoids potential problems.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: a cleaning and brushing device for 3D printed parts, including a frame, a support plate fixedly provided on one side of the frame, and cleaning brushes symmetrically rotated below the support plate. The cleaning brushes are driven by a motor fixed on the support plate. A rinsing pipe is provided on the support plate between the cleaning brushes. A movable and liftable part fixing frame is provided above the frame. Several soft metal hooks are provided below the part fixing frame. An ultrasonic cleaner and a rinsing mechanism are respectively provided on both sides inside the frame. The rinsing mechanism includes two parallel rinsing plates. Two sets of high-pressure spray structures with opposite spray directions are provided on the opposite surfaces of the rinsing plates. A water collection tank is provided inside the frame below the rinsing mechanism.

[0006] Furthermore, the two cleaning brushes rotate relative to each other.

[0007] Based on the above features, the relatively rotating cleaning brush can simultaneously clean the 3D printed parts from two directions, increasing the contact area and friction between the cleaning brush and the parts, improving cleaning efficiency, and enabling the dirt on the surface of the 3D printed parts to be removed more quickly and thoroughly.

[0008] Furthermore, a gantry frame is provided above the frame, and a U-shaped frame is provided below the gantry frame. The U-shaped frame is driven by a screw driver fixed on the gantry frame. The accessory is fixedly mounted below the U-shaped frame and driven by cylinders symmetrically fixed on the U-shaped frame. The two cylinders work synchronously.

[0009] Based on the above features, the lead screw driver and cylinder enable the accessory holder to move the 3D printed accessory stably in both horizontal and vertical directions. The synchronous operation of the two cylinders ensures that the accessory holder remains horizontal during lifting and lowering, preventing the accessory from tilting or falling, thus achieving effective cleaning.

[0010] Furthermore, the inner side of the frame is provided with a carrier plate for fixing the ultrasonic cleaner, and a support frame is symmetrically provided below the carrier plate, and the support frame is fixedly installed inside the frame.

[0011] Based on the above features, the carrier plate and support frame provide a stable installation position for the ultrasonic cleaner, ensuring that the ultrasonic cleaner will not shake or shift during operation, thus guaranteeing stability during cleaning.

[0012] Furthermore, the high-pressure spray cleaning structure is configured in a one-to-one correspondence with the soft metal hook. The high-pressure spray cleaning structure includes high-pressure nozzles and spray cleaning grooves arranged opposite to each other, and the high-pressure nozzles and spray cleaning grooves in the same group are configured in a one-to-one correspondence.

[0013] Based on the above features, the high-pressure spray cleaning structure corresponds one-to-one with the soft metal hooks, enabling targeted high-pressure rinsing of each 3D printed part fixed to the soft metal hook, ensuring that each 3D printed part is thoroughly cleaned. The relatively arranged high-pressure nozzles and spray cleaning grooves can form a concentrated rinsing water flow, improving the rinsing effect and allowing fine particles to be washed away more quickly. Furthermore, the spray cleaning grooves can limit the position of the 3D printed parts, preventing them from shaking or becoming misaligned due to the large rinsing force, thus ensuring effective rinsing.

[0014] Furthermore, the edge of the spray washing groove is an arc surface, and the bottom surface of the spray washing groove is provided with a water guide groove facing the water collection tank.

[0015] Based on the above features, the curved surface can prevent the edge of the spraying groove from impacting and damaging the 3D printed parts. The design of the water guide channel can quickly guide the fine particles and sewage washed down into the water collection tank, avoiding the accumulation of particles in the spraying groove and causing secondary pollution to the 3D printed parts, which is conducive to achieving efficient cleaning.

[0016] Furthermore, the water collection trough is fixedly connected to the inner wall of the frame by bolts, and a drain pipe is provided below the water collection trough.

[0017] Based on the above features, the water collection tank, which is fixed by bolts, is securely installed and easy to disassemble and clean. The drain pipe below the water collection tank facilitates the timely discharge of sewage, keeping the inside of the equipment clean.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] It can perform cleaning and washing work in large batches: Several soft metal hooks are set under the accessory fixing frame to stably fix multiple 3D printed accessories. With the help of two sets of high-pressure spray washing structures, multiple 3D printed accessories can be sprayed and washed at the same time, thus meeting the cleaning needs of large batches of 3D printed accessories.

[0020] To facilitate the timely removal of fine particles and avoid potential problems: the cleaning brush, together with the rinsing tube, can perform initial brushing of 3D printed parts, and the ultrasonic cleaner can further clean the 3D printed parts. The high-pressure spray cleaning structure has two sets set in opposite directions, which can perform high-pressure spray cleaning of 3D printed parts from different directions, which facilitates the timely removal of fine particles, ensures thorough cleaning, and avoids affecting subsequent use.
