Description

Technical Field

[0001] The utility model relates to the technical field of color mixing of consumable materials for 3D printing, in particular to a color mixing device for consumable materials for 3D printing. Background Art

[0002] A 3D printing consumables color mixing device is a device used to mix and adjust the color of 3D printing materials. It usually includes a mixing chamber and several control systems, which are used to mix 3D printing consumables of different colors (such as plastic particles or silk threads) into the required color. The device uses an automated control system to accurately add consumables of different colors into the mixing chamber according to preset proportions, and ensures uniform mixing through stirring, heating or other physical methods. In this way, users can customize consumables of specific colors according to design requirements to achieve the desired color effect during the 3D printing process. The color mixing device may also be equipped with a monitoring system to monitor color changes during the mixing process in real time to ensure that the final output consumable color meets expectations. This device improves the color consistency of 3D printing materials and the visual effect of printed works;

[0003] A search revealed a Chinese patent application with publication number CN219214115U, which discloses a color mixing device for 3D printing consumables. The patent describes a mixing mechanism that optimizes the color mixing performance of the mixing device during the preparation of 3D printing consumables. The mixing shaft of the mixing device is reinforced with the main and secondary paddles of the mixing mechanism. The mixing shaft, along with the mixing mechanism, stirs the 3D printing consumables, effectively mixing the colorant before coloring. This improves the color mixing efficiency of the mixing device. After coloring, the colorant within the mixing device is vibrated and discharged from a pipe at the bottom of the tank, resulting in a technical solution for mixing and coloring the 3D printing consumables.

[0004] In this solution, although the effect of efficient color mixing is achieved, the material will adhere to the inner wall of the discharge pipe due to its adhesion when being discharged. After the discharge is completed, the material attached to the inner wall of the pipe will harden over time. Over time, the inner diameter of the pipe gradually becomes smaller, and the discharge speed gradually becomes slower, which leads to the problem of pipe blockage. In order to solve this technical problem, the utility model proposes a color mixing device for consumables for 3D printing. Utility Model Content

[0014] (3) Beneficial effects

[0015] The utility model provides a color mixing device for 3D printing consumables. It has the following beneficial effects:

[0016] (1) The raw materials in the mixing box are fully mixed and then discharged through the discharge pipe. However, due to the adhesion of the raw materials, they are easily blocked on the inner wall of the pipe. In order to solve this problem, the electric push rod on the horizontal plate is started. This push rod pushes the vertical plate to move on the horizontal plate. The vertical plate is stabilized on the horizontal plate by the limit block and keeps the moving direction consistent through the slide. The movement of the vertical plate drives the rotating shaft and the dragon leaf attached to it to insert into the discharge pipe. The motor three is started to rotate the rotating shaft, thereby driving the dragon leaf to rotate. During the rotation process, the dragon leaf effectively scrapes and cleans the adhered raw materials on the inner wall of the discharge pipe, preventing the pipe from being blocked. This coordination mechanism not only ensures the smooth discharge of raw materials, but also improves the overall work efficiency and avoids the problem of shutdown or efficiency reduction caused by blockage.

[0017] (2) After the raw materials are poured into the mixing box, start motor 1, which drives the threaded rod to rotate. The rotation of the threaded rod pushes the connecting block 1 to move along its axial direction, thereby driving the movement of the connecting rod. The connecting rod pushes the support plate to move left and right under the restriction of the slide rod and the positioning column through its movement. The movement of the support plate simultaneously drives the rotating column on motor 2 to rotate. The rotation of the rotating column then drives the stirring rod to stir. This process ensures that the mixing is fully uniform. At the same time, the cooperation of connecting block 2 ensures the stability and consistency of the mixing process. During the mixing process, the scraper on the rotating column also moves accordingly, effectively scraping off the raw materials adhering to the inner wall and bottom of the mixing box, preventing material accumulation. Overall, this cooperation not only improves the uniformity of the mixing, but also simplifies the subsequent cleaning process, significantly improving the work efficiency and operation convenience of the system.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A color mixing device for 3D printing consumables, including a mixing box 1, a horizontal plate 14 is fixedly connected to the outer wall of the mixing box 1, an electric push rod 15 is fixedly connected to the top left end of the horizontal plate 14, and the output end of the electric push rod 15 is fixedly connected to the vertical plate 16, a slide groove 18 is opened inside the horizontal plate 14, and the vertical plate 16 corresponds to the slide groove 18, and the vertical plate 16 is slidably connected in the slide groove 18, and both sides of the top of the vertical plate 16 are fixedly connected to the limit blocks 17, and the limit blocks 17 are slidably connected to the upper surface of the horizontal plate 14, and the outer wall of the bottom end of the vertical plate 16 is fixedly connected to a motor three 19, and the output end of the motor three 19 is fixedly connected to a rotating shaft 20, and the other end of the rotating shaft 20 is provided with a dragon leaf 22, and a discharge pipe 21 is fixedly connected to the mixing box 1, and the dragon leaf 22 corresponds to the discharge pipe 21, and the dragon leaf 22 is rotatably connected in the discharge pipe 21.

[0026] The mixed printing materials are discharged through the discharge pipe 21, but due to the adhesiveness of the materials, they are easy to adhere to the inner wall of the discharge pipe 21, causing a blockage problem. In order to solve this problem, the system starts the electric push rod 15 on the horizontal plate 14. This push rod pushes the vertical plate 16 to move left and right. The vertical plate 16 is fixed to the horizontal plate 14 by the limit block 17. At the same time, the slide groove 18 ensures that its movement direction remains consistent. During the movement of the vertical plate 16, it will drive the rotating shaft 20 and the dragon leaf 22 attached thereto to insert into the discharge pipe 21. After starting the motor three 19, the motor drives the rotating shaft 20 to rotate, thereby driving the dragon leaf 22 to rotate, cleaning the raw materials adhered to the inner wall of the discharge pipe 21. This cleaning mechanism effectively prevents blockage of the discharge pipe 21, ensures the smooth discharge of raw materials, and significantly improves the working efficiency of the system.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the outer wall above the mixing box 1 is fixedly connected to a motor 2, the output end of the motor 2 is fixedly connected to a threaded rod 3, and the other end of the threaded rod 3 is rotatably connected to the mixing box 1, a support plate 6 is provided inside the mixing box 1, both ends of the support plate 6 are fixedly connected to connecting rods 5, and the other end of each connecting rod 5 is fixedly connected to a connecting block 4, one side of the connecting block 4 is threadedly connected to the outer wall of the threaded rod 3, a sliding rod 7 is fixedly connected to the top of the mixing box 1, and the other side of the connecting block 4 is slidably connected to the outer wall of the sliding rod 7, and the interior of the mixing box 1 is fixedly connected There is a pair of positioning columns 8, and the support plate 6 is slidably connected to the positioning columns 8. The top of the support plate 6 is fixedly connected to a motor 29, and the output end of the motor 29 is fixedly connected to a rotating column 10. The outer wall of the rotating column 10 is fixedly connected to multiple stirring rods 11, and the stirring rods 11 are rotatably connected to the mixing box 1. The outside of the rotating column 10 is provided with a connecting block 2 12, and both sides of the connecting block 2 12 are fixedly connected with a scraper plate 13, and the scraper plate 13 consists of two vertical plates and a horizontal plate perpendicular to the vertical plates. At the same time, the scraper plate 13 slides tightly against the inside of the mixing box 1, and heating plates 23 are provided on both sides of the mixing box 1.

[0028] After the material is poured into the mixing box 1, the motor 2 9 on the top of the support plate 6 is started to drive the rotating column 10 to rotate. The rotation of the rotating column 10 drives the stirring rod 11 to stir, so as to achieve uniform mixing of the materials. At the same time, the motor 12 is started. The motor 12 rotates the threaded rod 3 to make the connecting block 14 move back and forth along the threaded rod. The movement of the connecting block 14 pushes the support plate 6 to move in the left and right directions through the connecting rod 5. The movement of the support plate 6 is kept in the same direction by the limiting function of the sliding rod 7 and the positioning column 8 to ensure sufficient stirring. During the movement of the support plate 6, the scraper plate 13 on the rotating column 10 also scrapes the inner wall and bottom of the mixing box 1 back and forth with the movement of the rotating column to remove the raw materials adhering to the wall. This not only ensures the uniform mixing effect, but also facilitates the subsequent cleaning work, thereby significantly improving the overall work efficiency.

[0029] Working principle: when the staff needs to make consumables for 3D printing, they first pour the materials into the mixing box 1, and start the motor 2 9 on the top of the support plate 6. Under the action of the motor 2 9, the rotating column 10 is driven to rotate. When the rotating column 10 rotates, the stirring rod 11 is driven to stir. At the same time, start the motor 1 2, and under the action of the motor 1 2, the threaded rod 3 is driven to rotate. When the threaded rod 3 rotates, it drives the connecting block 1 4 to move back and forth. When the connecting block 1 4 moves, it drives the support plate 6 on the connecting rod 5 to move left and right. The support plate 6 is limited by the sliding rod 7 and the positioning column 8 to ensure that the support plate 6 maintains the same direction when moving. Through their cooperation, the stirring is more sufficient. When the support plate 6 moves, it drives the scraper plate 13 on the rotating column 10 to move back and forth. At the same time, the scraper plate 13 scrapes the raw materials on the inner wall and the low wall of the mixing box 1. The mixed printing materials are discharged through the discharge pipe 21. Since the materials have adhesiveness, they will stick to the inner wall of the discharge pipe 21. Over time, they will become blocked. At this time, the electric push rod 15 on the horizontal plate 14 is started. The vertical plate 16 is pushed to move left and right under the action of the electric push rod 15. The vertical plate 16 is limited on the horizontal plate 14 by the limit block 17, and the slide groove 18 ensures that the vertical plate 16 maintains the same direction when moving. When the vertical plate 16 moves, the rotating shaft 20 and the dragon leaf 22 are driven to insert into the discharge pipe 21. At this time, the motor 3 19 is started again, which will drive the rotating shaft 20 to rotate, thereby driving the dragon leaf 22 to rotate. The raw materials blocked inside the discharge pipe 21 are cleaned through the dragon leaf 22, avoiding blockage, making the discharge smoother and improving work efficiency.
