Description

Technical Field

[0001] This utility model relates to the field of 3D printing materials technology, and in particular to a material mixing mechanism for 3D printing material production. Background Technology

[0002] In the field of additive manufacturing 3D printing technology, the preparation of high-performance printing materials is one of the key steps. These materials usually have the characteristics of high viscosity, high solid content and easy sedimentation. The mixing and stirring process in their production plays a decisive role in the quality of the final printed product.

[0003] In traditional mixing devices, materials are placed into the mixer and stirred by the mixing rack. Then, the materials are discharged through the bottom discharge valve. However, after stirring, some materials cannot flow out completely from the bottom discharge valve by gravity. Some materials adhere to the inner wall and bottom of the tank, resulting in the waste of valuable materials and the risk of cross-contamination when changing material types. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material mixing mechanism for 3D printing material production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material mixing mechanism for 3D printing material production includes a frame, two mounting brackets fixedly connected to the top of the frame, a fixed bracket rotatably connected between the two mounting brackets, a tank fixedly connected inside the fixed bracket, a connecting bracket fixedly connected to one side of the tank, a connecting seat fixedly connected to one side of the connecting bracket, a fixed seat fixedly connected to the top of the frame, a cylinder rotatably connected to one side of the fixed seat, and one end of the cylinder rotatably connected to the connecting seat. The tank is equipped with a mixing component for mixing materials.

[0007] As a further embodiment of this utility model, the stirring assembly includes a motor, which is fixedly connected to one side of the tank. One end of the motor output shaft is connected to a rotating shaft via a coupling. Two connecting plates are fixedly connected to the outer side of the rotating shaft, and multiple stirring columns are fixedly connected to one side of the two connecting plates.

[0008] As a further embodiment of this utility model, a feeding port is provided on the outer side of the tank body, and a cover plate is rotatably connected to the outer side of the tank body via a hinge, with the cover plate located inside the feeding port, and a handle is fixedly connected to the outer side of the cover plate.

[0009] As a further embodiment of this utility model, one end of the tank is rotatably connected to an end cap via a hinge. Both the end cap and the outer side of the tank are fixedly connected to a fixing block. One side of each of the two fixing blocks is provided with a threaded hole, and a locking screw is threaded into each of the two threaded holes.

[0010] As a further embodiment of this utility model, a collection box is fixedly connected to one side of the frame, and the collection box is located below the end cap.

[0011] As a further embodiment of this utility model, a scraper is fixedly connected to one side of each of the two connecting plates, and the scraper is in contact with the inner wall of the tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model is equipped with a simultaneous cylinder, which drives the connecting seat to rotate the tank around the fixed frame, allowing the tank to tilt. With the opening of the end cap, the material is more thoroughly discharged into the collection box under the action of gravity, avoiding the problem of incomplete discharge caused by material adhesion in traditional bottom discharge valves. This reduces the waste of precious materials and the risk of cross-contamination when changing different materials, thus improving the practicality and economy of the stirring mechanism.

[0014] 2. This utility model is equipped with a scraper. By contacting the inner wall of the tank, when the motor drives the rotating shaft to rotate, the connecting plate will drive the scraper to rotate synchronously. The scraper can continuously scrape off the material adhering to the inner wall of the tank during the stirring process, effectively reducing material residue.

[0015] 3. This utility model has a matching structure of end cap and locking screw. When it is necessary to clean the inside of the tank or perform maintenance, the end cap can be opened by unscrewing the locking screw, which makes it easy for operators to directly and thoroughly clean the inner wall of the tank and the stirring components. This reduces the difficulty of cleaning, further avoids the impact of residual materials on subsequent production, and also provides convenient conditions for equipment maintenance.

[0020] 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. The described embodiments are only some embodiments of the present utility model, 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.

[0021] Reference Figures 1-3 A 3D printing material production material mixing mechanism includes a frame 1. Two mounting brackets are bolted to the top of the frame 1, and a fixed bracket 6 is rotatably connected between the two mounting brackets. A tank 3 is bolted inside the fixed bracket 6. A connecting bracket 2 is bolted to one side of the tank 3, and a connecting seat 12 is bolted to one side of the connecting bracket 2. A fixed seat 10 is bolted to the top of the frame 1. A cylinder 11 is rotatably connected to one side of the fixed seat 10, and one end of the cylinder 11 is rotatably connected to the connecting seat 12. In use, the 3D printing material to be mixed is first poured into the tank 3. The cylinder 11 is started by an external control device. The piston rod of the cylinder 11 extends or retracts, driving the connecting seat 12 and the connecting bracket 2 to move, thereby causing the fixed bracket 6 to rotate around the mounting bracket, thereby adjusting the tilt angle of the tank 3 to facilitate the subsequent mixing and pouring of materials.

[0022] The tank body 3 is equipped with a stirring assembly for mixing materials. The stirring assembly includes a motor 13, which is fixed to one side of the tank body 3 by bolts. One end of the output shaft of the motor 13 is connected to a rotating shaft 14 through a coupling. Two connecting plates 16 are fixed to the outside of the rotating shaft 14 by bolts. Multiple stirring columns 17 are fixed to one side of the two connecting plates 16 by bolts. When in use, the motor 13 is started, and the output shaft of the motor 13 drives the rotating shaft 14 to rotate. The stirring columns 17 on the rotating shaft 14 rotate accordingly, which fully stirs the materials in the tank body.

[0023] In this invention, a feeding port is provided on the outer side of the tank body 3. A cover plate 5 is rotatably connected to the outer side of the tank body 3 via a hinge, and the cover plate 5 is located inside the feeding port. A handle 4 is fixed to the outer side of the cover plate 5 by bolts. An end cover 7 is rotatably connected to one end of the tank body 3 via a hinge. Fixing blocks are welded to both the end cover 7 and the outer side of the tank body 3. Threaded holes are provided on one side of both fixing blocks, and locking screws 8 are threaded into the two threaded holes. In use, the cover plate 5 can be opened to add material to the tank body 3. The handle 4 allows the operator to easily open the cover plate 5. The end cover 7 can be opened by unscrewing the locking screws 8, making it easy for the operator to directly and thoroughly clean the inner wall of the tank body 3 and the stirring components. This reduces the difficulty of cleaning, further avoids the impact of residual materials on subsequent production, and also provides convenient conditions for equipment maintenance.

[0024] In particular, a collection box 9 is fixed to one side of the frame 1 by bolts, and the collection box 9 is located below the end cover 7. Scrapers 15 are fixed to one side of each of the two connecting plates 16 by bolts, and the scrapers 15 are in contact with the inner wall of the tank 3. When in use, the collected material can be collected through the collection box 9, and the inner wall of the tank 3 can be scraped and cleaned through the scrapers 15, effectively reducing material residue.

[0025] Working Principle: In actual operation, when material mixing is required, the operator first opens the cover plate 5 through handle 4, and puts the 3D printing material to be mixed into the tank 3 through the feeding port. Then, the cover plate 5 is closed to ensure that the material does not leak out during the mixing process. Next, the motor 13 is started. The output shaft of the motor 13 drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the stirring column 17 and the scraper 15 to rotate simultaneously through the connecting plate 16. The stirring column 17 thoroughly mixes the material in the tank, while the scraper 15 continuously scrapes the inner wall of the tank 3 during rotation to prevent material adhesion. After mixing is completed, Start cylinder 11. The piston rod of cylinder 11 extends and retracts, causing the connecting seat 12 to move. This causes the fixed frame 6 and the tank 3 to rotate and tilt around the mounting frame. At this time, unscrew the locking screw 8 and open the end cover 7. The material in the tank will slide down the inclined inner wall of the tank 3 under the action of gravity and fall into the collection box 9 below to complete the unloading. After unloading or when cleaning and maintenance are required, open the end cover 7 again. The operator can directly rinse or wipe the inner wall of the tank 3, the stirring column 17 and the scraper 15. After cleaning, tighten the end cover 7 again and tighten the locking screw 8. Then the next batch of material can be stirred.

[0026] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
