Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printers, and in particular relates to a screen structure for a 3D printer. Background Art

[0002] Paint, also known as varnish, is a commonly used decorative material applied to surfaces to be protected or decorated, forming a firmly adherent, continuous film. It is typically a viscous liquid composed primarily of resins, oils, and emulsions, with or without pigments, fillers, and additives, prepared using organic solvents or water. During the paint processing process, a mixing tank or reactor is used to evenly agitate and mix the paint. A common agitator is located within the tank, where a motor drives the agitator shaft to stir the paint. After agitation, the mixed paint is discharged through a discharge pipe and valve at the bottom of the tank. Due to the high viscosity of paint, the paint is typically difficult to mix.

[0003] According to CN 218871906 U, a screen structure for a 3D printer includes a support frame, a paint stirring tank is fixedly arranged on the inner side of the support frame, a tank cover is provided on the top of the paint stirring tank, and electric-controlled telescopic rods are fixedly installed on both sides of the top of the tank cover. A cleaning pressure ring located inside the paint stirring tank is fixedly arranged between the two electric-controlled telescopic rods, and a rubber scraper ring is fixedly arranged on the periphery of the cleaning pressure ring. The utility model provides a screen structure for a 3D printer. The paint stirring device adopts paddle stirring instead of blade stirring to make the stirring shaft surface smoother. A lifting cleaning pressure ring is added to the inner side wall of the stirring tank. After the mixing is completed, the rubber scraper ring and the inner scraper ring can scrape the inner side wall of the tank body and the stirring shaft surface respectively during the discharge process, thereby accelerating the downstream concentration of the attached paint, thereby greatly improving the discharge efficiency of the stirred paint and providing convenience for cleaning the stirring tank.

[0004] Although it realizes the function of stirring the paint, in actual use, due to the single stirring direction, the paint moves in the tank following the stirring direction, resulting in poor stirring effect and slow stirring efficiency. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0025] like Figure 1 As shown;

[0026] A screen structure for a 3D printer comprises a lifting support assembly 1 and a mixing tank 2 for stirring and mixing coatings.

[0027] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although it realizes the function of stirring the paint, in actual use, due to the single stirring direction, the paint moves in the tank following the stirring direction, resulting in poor stirring effect and slow stirring efficiency." In combination with actual use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve this technical problem, a screen structure for a 3D printer is provided on this basis.

[0028] like Figure 1-4 As shown in the figure;

[0029] In combination with the above content, a dual-axis stirring assembly 3 is provided on the lifting support assembly 1, and a tank body rotating assembly 4 is provided on the lifting support assembly 1. The tank body rotating assembly 4 includes a support 41 fixed on the lifting support assembly 1, and a circle of driven gears 42 and a circle of T-shaped limit rings 43 fixed on the mixing tank 2.

[0030] In an optional embodiment, a T-shaped limit groove 46 is provided on the support 41, a reduction motor 44 is installed on the support 41, a driving gear 45 is fixed on the output shaft of the reduction motor 44, the T-shaped limit ring 43 matches the T-shaped limit groove 46, and the T-shaped limit ring 43 is clamped inside the T-shaped limit groove 46 and rotates inside the T-shaped limit groove 46, and the driving gear 45 is engaged with the driven gear 42.

[0031] In this example, the driving gear 45 is driven to rotate by the reduction motor 4. Since the driving gear 45 is engaged with the driven gear 42, the driven gear 42 is driven to rotate. At the same time, the mixing tank 2 rotates accordingly and drives the T-shaped limit ring 43 to rotate inside the T-shaped limit groove 46, playing a guiding role, thereby rotating the paint inside the mixing tank.

[0032] In an optional embodiment, the biaxial stirring assembly 3 includes a fixed base 31 fixed to the lifting support assembly 1. A forward stirring rod 32 and a reverse stirring rod 33 are provided at the left end of the fixed base 31 via bearings. A first reduction motor 34 is fixed to the right end of the fixed base 31. A driving wheel 35 is fixed to the output shaft of the first reduction motor 34. A first driving gear 36 and a driven wheel 37 are provided on the forward stirring rod 32. A first driven gear 38 is fixed on the reverse stirring rod 33. The driving wheel 35 and the driven wheel 37 are connected by a belt 39. The first driving gear 36 and the first driven gear 38 are meshed with each other.

[0033] In this example: the first reduction motor 34 drives the driving wheel 35 to rotate, and the driving wheel 35 drives the driven wheel 37 to rotate through the belt 39, thereby driving the positive stirring rod 32 to rotate in the forward direction. Since the first driving gear 36 on the positive stirring rod 32 is engaged with the first driven gear 38 on the reverse stirring rod 33, the reverse stirring rod 33 is driven to rotate in the reverse direction, and then the positive stirring rod 32 and the reverse stirring rod 33 are used to rotate the paint inside the mixing tank 2 in different directions.

[0034] Working principle of this utility model:

[0035] The first reduction motor 34 drives the driving wheel 35 to rotate, and the driving wheel 35 drives the driven wheel 37 to rotate through the belt 39, thereby driving the positive stirring rod 32 to rotate forward. Since the first driving gear 36 on the positive stirring rod 32 is meshed with the first driven gear 38 on the reverse stirring rod 33, the reverse stirring rod 33 is driven to rotate in the reverse direction, and then the positive stirring rod 32 and the reverse stirring rod 33 are used to rotate the paint inside the mixing tank 2 in different directions. Then the reduction motor 4 is started to drive the driving gear 45 to rotate. Since the driving gear 45 is meshed with the driven gear 42, the driven gear 42 is driven to rotate. At the same time, the mixing tank 2 follows and rotates, and drives the T-shaped limit ring 43 to rotate inside the T-shaped limit groove 46, which plays a guiding role, thereby rotating the paint inside the mixing tank. By stirring the paint in different directions and cooperating with the rotation of the mixing tank, the mixing effect is better and the paint mixing efficiency is improved.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
