Description

Technical Field

[0001] This utility model relates to the field of paint production technology, specifically to a powder mixing and adding device for paint production. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving protective, decorative, marking, and other special purposes. During the paint production process, powder is added. The addition of powder increases the hardness of the paint, improves the abrasion resistance and adhesion of the coating, thereby enhancing the quality of the coating. The particles in the powder can fill the tiny pores in the paint, thus increasing the density and hardness of the coating. Furthermore, the particles in the powder can combine with other components in the paint, thereby enhancing the adhesion and abrasion resistance of the coating.

[0003] When using existing mixing and adding devices, the powder should be added gradually after the liquid components are evenly mixed. However, the powder is prone to accumulating when it is added, which can cause clumping, sedimentation and other adverse phenomena when the powdered material is mixed inside the liquid components, affecting the quality of the paint after production. Utility Model Content

While the screen frame filters out the dispersed powder, the mixing mechanism mixes the paint and powder inside the mixing tank. This solves the problem in existing mixing and adding devices where the powder is not dispersed, leading to clumping and sedimentation when stirred into the liquid paint. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example 1

[0049] See Figure 1-4 A powder mixing and adding device for paint production includes a main component 1, which includes: a mixing tank 11 with an inlet 12 connected to its top; and an outlet 13 connected to the bottom of the mixing tank 11. A dispersing component 2 is mounted on the mixing tank 11, comprising: a support 211 symmetrically arranged on the top of the mixing tank 11; a reciprocating screw 21 rotatably connected between the supports 211; a motor 22 mounted on the top of the mixing tank 11, with its output shaft fixedly connected to one end of the reciprocating screw 21; and a threaded block 23 threadedly connected to the reciprocating screw 21. The following components are provided: rod 21; connecting plate 24, fixedly connected to the outer wall of the threaded block 23; through groove 1 241, opened at the top of the mixing tank 11, the connecting plate 24 passing through the through groove 1 241 and extending into the interior of the mixing tank 11; screen frame 25, fixedly connected to the bottom of the connecting plate 24; through groove 251, opened at the top of the mixing tank 11; frame 261, symmetrically arranged at the top of the mixing tank 11; feed inlet 26, arranged between the frames 261; discharge pipe 262, connected through to the bottom of the feed inlet 26; mixing mechanism 27, arranged on the mixing tank 11 and the reciprocating screw 21. The mixing mechanism 27 includes: a first bevel gear 271, fixedly connected to the outer wall of the reciprocating screw 21; a rotating shaft 272, rotatably connected to the mixing tank 11, with the top of the rotating shaft 272 extending through and above the mixing tank 11; a second bevel gear 273, fixedly connected to the top of the rotating shaft 272 and meshing with the first bevel gear 271; and stirring rods 274, symmetrically and fixedly connected to the outer wall of the rotating shaft 272. Multiple sets of discharge pipes 262 are symmetrically arranged, all communicating with the inlet 26.

[0050] During use, the operator adds paint into the mixing tank 11 through the inlet 12. When powder needs to be added, the operator pours the powder into the inlet 26 and starts the motor 22. The motor 22 drives the reciprocating screw 21 to rotate. The threaded block 23 connected to the reciprocating screw 21 drives the screen frame 25 to move back and forth along the extension direction of the reciprocating screw 21 via the connecting plate 24. The powder at the inlet 26 falls into the screen frame 25 below through the outlet pipe 262. When the screen frame 25 moves, it screens and disperses the powder inside, increasing the dispersion area of ​​the powder. The screen frame 25 is relatively wide, making... As the sieve frame 25 reciprocates, the discharge pipe 262 still correctly falls into the sieve frame 25. While the sieve frame 25 sieves out the dispersed powder, the mixing mechanism 27 mixes the paint and powder inside the mixing tank 11: when the motor 22 drives the reciprocating screw 21 to rotate, the bevel gear 271 outside the reciprocating screw 21 drives the bevel gear 273 to rotate. The bevel gear 273 causes the rotating shaft 272 to rotate. The stirring rod 274 on the outer wall of the rotating shaft 272 mixes the paint and powder inside the mixing tank 11. Because the powder is relatively dispersed, it is easy to improve the mixing effect and reduce the occurrence of agglomeration and sedimentation. Multiple sets of discharge pipes 262 are arranged sequentially above the sieve frame 25, so that the powder at the inlet 26 is evenly distributed into each discharge pipe 262, increasing the area of ​​powder falling into the sieve frame 25, improving the screening efficiency of the sieve frame 25, and making it easier to improve the uniformity of the powder screened by the sieve frame 25, thus facilitating subsequent mixing with paint.

[0051] Example 2

[0052] An auxiliary function has been added based on Embodiment 1.

[0053] See Figure 1-4 The mixing tank 11, the connecting plate 24, and the first through-slot 241 are provided with a shielding assembly 3. The shielding assembly 3 includes: a groove 31, symmetrically formed on the mixing tank 11 and connected to the first through-slot 241; a spring 32, symmetrically arranged on the inner side wall of the groove 31; and a baffle 33, symmetrically and fixedly connected between the spring 32 and the first through-slot 241. The width of the groove 31 and the baffle 33 is greater than the width of the first through-slot 241 and the connecting plate 24. A cover 4 is slidably connected to the top of the mixing tank 11, and the cover 4 is located at the top of the second through-slot 251. A stirring rod 274 is symmetrically arranged on the outer side wall of the rotating shaft 272. One end of the stirring rod 274 is fixedly connected to a connecting rod 275, and the connecting rod 275 is slidably connected to the inner side wall of the mixing tank 11.

[0054] When the threaded block 23 drives the screen frame 25 to reciprocate via the connecting plate 24, the connecting plate 24 moves within the through groove 241. The shielding component 3 shields the exposed through groove 241 without affecting the movement of the connecting plate 24, preventing powder from overflowing from the through groove 241 and polluting the surrounding environment. When the connecting plate 24 moves to the left within the through groove 241, the baffle 33 on the left side of the connecting plate 24 is pushed into the groove 31, the spring 32 on the left side contracts, and the baffle 33 on the right side is moved out of the groove 31, stretching the groove 31 on the right side. The length of the baffle 33 is greater than half the length of the through groove 241, so that when the connecting plate 24 moves, the shielding components 3 on both sides shield the through groove 241 respectively, preventing powder from escaping from the mixing tank 11. While the sieve frame 25 moves to screen, the operator slides the cover 4 above the second channel 251, covering the top of the second channel 251 to prevent powder from overflowing from the second channel 251 into the mixing tank 11. When the rotating shaft 272 drives the stirring rod 274 to mix the paint and powder inside the mixing tank 11, the stirring rod 274 outside the rotating shaft 272 drives the connecting rod 275 to slide on the inner wall of the mixing tank 11. The connecting rod 275 scrapes off the paint and powder adhering to the inner wall of the mixing tank 11 to avoid affecting the uniformity of mixing.
