Description

Technical Field

[0001] The utility model relates to the technical field of wax material anti-solidification, in particular to a material anti-solidification mechanism of a 3D wax model printer. Background Art

[0002] When using a 3D wax printer, red wax resin needs to be poured into a tray and cured by ultraviolet light to make the required wax model. During the production of liquid materials such as red wax resin, in order to prevent the material from curing prematurely, some chemical additives can be added to slow down the curing speed of the resin. In the process of adding chemicals, a mixer is needed to fully mix the chemicals and materials to ensure the anti-curing performance of the material.

[0003] At present, the existing mixer mainly mixes chemicals and materials through a stirring shaft. After the mixing is completed, more materials will be attached to the outside of the stirring shaft. Since the existing mixer is fixed as a whole, it is not convenient for the staff to clean the stirring shaft set in the machine body, which will cause the material to agglomerate on the stirring shaft and affect the subsequent mixing quality of the material. For this reason, we propose a material anti-curing mechanism for a 3D wax model printer to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A material anti-curing mechanism of a 3D wax model printer includes a mixing box 1, the top of the mixing box 1 is covered with an upper cover 2, and a feed pipe 3 is arranged inside the upper cover 2, the bottom end of the mixing box 1 is connected to a discharge pipe 4, and a sealing plate is arranged at the bottom end of the discharge pipe 4, which is not shown in the figure. When material is needed, the sealing plate can be opened. During the mixing process, the discharge pipe 4 can be blocked with the sealing plate. A motor 5 is installed above the upper cover 2, and the output end of the motor 5 passes through the inner wall of the upper cover 2 and is connected to a rotating shaft 6, and a stirring shaft 7 is connected to the outer side of the rotating shaft 6. A fixed block 17 is connected to the side of the mixing box 1, and a cylinder 16 is connected to the top of the fixed block 17. The telescopic principle of the cylinder 16 is the prior art and will not be described in detail here. The top of the cylinder 16 is fixedly connected to the upper cover 2.

[0023] Further, see Figure 2 It can be known that a buffer pad 19 is glued to the bottom end of the upper cover 2, and a material drop groove is opened inside the buffer pad 19 at a position corresponding to the support frame 13, and the lower side of the buffer pad 19 is in contact with the top of the mixing box 1. By opening the material drop groove, the normal falling of the material can be guaranteed, and the buffer pad 19 connected to the bottom end of the upper cover 2 can prevent the upper cover 2 from directly and rigidly contacting the mixing box 1, so as to realize the protection of the upper cover 2.

[0024] Further, see Figure 2 and Figure 3It can be known that a bevel gear set 8 is sleeved on the outer side of the rotating shaft 6, and linkage shafts 10 are symmetrically connected at both ends of the bevel gear set 8. The sides of the linkage shafts 10 that are away from each other are connected through bearings and the inner wall of the support frame 13, and the top of the support frame 13 is fixedly connected to the upper cover 2. Agitating blades 11 are equidistantly distributed on the outer side of the linkage shaft 10. The bevel gear set 8 is composed of three groups of bevel gears, and the three groups of bevel gears are respectively fixedly sleeved on the ends of the two groups of linkage shafts 10 that are close to each other and the outside of the rotating shaft 6. Therefore, when the rotating shaft 6 rotates, it can drive the two groups of linkage shafts 10 to reverse rotation, so that the agitating blades 11 can reverse rotation inside the mixing box 1 to ensure the mixing effect of the materials. Since the linkage shaft 10 is connected to the support frame 13 through bearings, the reliability of the linkage shaft 10 during rotation can be effectively guaranteed.

[0025] Further, see Figure 2 and Figure 3 It can be known that the support frame 13 is configured as a U-shaped structure, and a sleeve 14 is connected to the center position of the bottom end of the support frame 13. The sleeve 14 is movably sleeved at the bottom end position of the rotating shaft 6. When in use, the setting of the sleeve 14 can effectively ensure the stability of the rotating shaft 6 during rotation.

[0026] Further, see Figure 3 It can be known that a protective cover 9 is provided on the outer side of the bevel gear set 8, and the bottom end of the protective cover 9 is connected to the support frame 13 through a support rod 15. By setting the protective cover 9, the bevel gear set 8 can be protected, and by setting the support rod 15, the protective cover 9 can be supported.

[0027] Further, see Figure 3 It can be seen that the inside of the stirring blade 11 is equidistantly provided with slots 12, and the slots 12 are arranged in a long strip shape. The slots 12 arranged in a long strip shape can effectively reduce the resistance when the stirring blade 11 rotates, thereby effectively ensuring the service life of the stirring blade 11.

[0028] Further, see Figure 2 and Figure 4 It can be known that a connecting rod 18 is connected to the side of the buffer pad 19 away from the cylinder 16, and the connecting rod 18 is arranged as an L-shaped structure. The outer wall of the mixing box 1 is provided with a slideway adapted to the connecting rod 18. The connecting rod 18 is arranged with the L-shaped structure, so when the upper cover 2 is pushed on the cylinder 16, the connecting rod 18 can slide along the inner wall of the slideway, thereby effectively ensuring the stability of the upper cover 2 during the up and down lifting process.

[0029] Working principle: When the utility model is used, the staff can first pour the materials and additives to be mixed into the mixing box 1 through the feed pipe 3, and then the staff can start the motor 5, so that the rotating shaft 6 connected to the bottom end of the output end continuously drives the stirring shaft 7 to rotate, so as to achieve the mixing of the materials. During the rotation of the rotating shaft 6, the bevel gear set 8 sleeved on the outside can drive the two sets of linkage shafts 10 to rotate in an annular manner, and the stirring blade 11 connected to the outside of the linkage shaft 10 can be continuously rotated, so that the materials in the mixing box 1 can be mixed from two directions, which can effectively ensure the mixing effect of the materials and additives;

[0030] After the mixing is completed, the staff can open the sealing plate arranged at the bottom end of the discharge pipe 4, and then the material inside the mixing box 1 can be guided out. After completing the unloading work, the staff can start the cylinder 16 to drive the upper cover 2 and the stirring shaft 7 to lift up. At this time, the stirring shaft 7 and the stirring blade 11 are able to extend out of the mixing box 1, so that the staff can use tools to scrape off the material attached to the stirring shaft 7 and the stirring blade 11 to realize the cleaning operation of the stirring shaft 7 and the stirring blade 11, thereby ensuring the subsequent normal use of the device. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
