Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a high-efficiency powder coating mixer. Background Art

[0002] Powder coating is a new type of solid powder coating without solvent. It is made of special resin, pigment, filler, curing agent and other additives, mixed in a certain proportion, and then prepared by hot extrusion, crushing and screening. Because no solvent is used, powder coating is harmless, efficient, resource-saving and environmentally friendly. Powder coating exists in the form of fine powder, which is completely different from general coating. Powder coating can be divided into two categories: thermoplastic powder coating and thermosetting powder coating. Thermoplastic powder coating has poor coating appearance (gloss and leveling) and poor adhesion to metal, so it is rarely used in the field of automotive coating. Automotive coating generally uses thermosetting powder coating.

[0003] During the processing of powder coatings, various powder materials need to be mixed evenly to achieve the best use effect. Some mixing equipment currently in use can already meet general use requirements. However, in actual application, since powder coatings need to be ground before mixing, this may cause larger particles of raw materials to not be mixed quickly and fully during mixing. Since the current stirring mechanism is mostly stirred by a single stirring shaft, the stirring effect is poor and the mixing efficiency is low, resulting in large defects in the powder coating after stirring. Therefore, an efficient powder coating mixer is urgently needed. 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 1-5 A high-efficiency powder coating mixer comprises a driving box 1, a reduction motor 2 is installed on one side of the upper part of the driving box 1, and a mixing barrel 3 is installed on the other side, the two sides of the mixing barrel 3 are connected and fixed by a fixing frame 4, and an upper cover 5 is installed on the upper cover of the mixing barrel 3, and a discharge port 6 is arranged at the lower part of the mixing barrel 3;

[0023] Furthermore, a driving rod 21 is rotatably installed at the inner bottom end of the mixing barrel 3, a spiral blade 11 is connected to the middle of the driving rod 21, and a plurality of friction blocks 12 are arranged on the upper part, and a side cover 8 is installed on the driving rod 21 through a bearing seat 10, and a half side cover 81 is installed on the side cover 8.

[0024] The upper and lower parts of the driving rod 21 are both provided with bearing seats 10 , and one end of the bearing seat 10 is connected to a connecting seat 83 provided in the side cover 8 .

[0025] Moreover, the side cover 8 is a hollow semi-cylindrical body, and a limiting groove 82 is provided at the cross-sectional ends of both sides of the side cover 8, and a half side cover 81 is installed in the limiting groove 82 by a slider. By setting the half side cover 81, the conveying effect of the spiral blade 11 can be effectively achieved and the stirring efficiency can be improved.

[0026] In addition, the side cover 8 is sleeved on the outside of the friction block 12, and a gap is provided between the inner wall of the side cover 8 and the friction block 12, wherein a plurality of notches are provided on the inner wall of the side cover 8. Through the cooperation between the notches provided on the side cover 8 and the friction block 12, the effect of crushing large-particle powder can be achieved.

[0027] Meanwhile, a transmission base 7 is disposed at the bottom of the driving rod 21 , and stirring rods 9 are disposed on both sides of the transmission base 7 , and the stirring rods 9 are drivingly connected to the driving rod 21 .

[0028] Furthermore, the spiral blade 11 is drivingly connected to the driving rod 21 , and a side cover 8 and a half side cover 81 are respectively sleeved and installed on the outer side away from the spiral blade 11 .

[0029] In this embodiment, during the installation of the mixing barrel, the side cover 8 is installed on the bearing seat 10 through the connecting seat 83 on the side cover 8, and the half side cover 81 is snap-fitted and installed on the side cover 8 through the limiting groove 82 provided on the side cover 8. In actual use, the powder coating to be processed is put into the mixing barrel 3, and the upper cover 5 is covered, and the reduction motor 2 is started at the same time.

At the same time, the rotation of the friction block 12 will drive the large particles of powder to rub and crush with the friction groove in the side cover 8, so that the large particles become small particles, and through the specified gap setting, the small particles will no longer be crushed.

[0030] At the same time, after the stirring is completed, the material is discharged through the discharge port 6 on the mixing barrel 3.

[0033] In the utility model, the driving rod 21 drives the stirring rod 9, the spiral blade 11 and the friction block 12 to rotate respectively, and cooperates with the setting of the side cover 8 to realize the mixing and stirring function of the paint, and the spiral blade 11 continuously transports the lower paint to the upper part during stirring, thereby ensuring the fluidity of the paint in the barrel, and through the coordinated setting of the friction block 12 and the side cover 8, large-particle powder can be further crushed, and at the same time, the mouth-shaped stirring rod 9 can effectively increase the stirring area and improve the stirring efficiency, and the side cover can be quickly disassembled and assembled, effectively improving the use efficiency of the mixer.
