Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating processing technology, specifically to an automatic turning mixer for thermosetting powder coatings. Background Technology
[0002] Powder coatings are a completely different form from ordinary coatings, existing as fine powders. Because they do not use solvents, they are called powder coatings. The main characteristics of powder coatings include: harmlessness, high efficiency, resource conservation, and environmental friendliness. There are two main categories: thermoplastic powder coatings and thermosetting powder coatings. Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers, and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide-based, cellulose-based, and polyester-based. In the production process of thermosetting powder coatings, various raw materials and additives need to be mixed. However, existing mixing equipment has low mixing efficiency, resulting in insufficient mixing of raw materials, and slow material flow at the outlet easily causes blockages, affecting subsequent processing. Utility Model Content
[0003] The main purpose of this utility model is to solve the above-mentioned technical problems to a certain extent, and to propose an automatic turning mixer for thermosetting powder coatings, which can improve the efficiency of raw material mixing and solve the problem of easy blockage at the discharge port.
[0004] The above-mentioned problems to be solved by this utility model are achieved through the following technical solution: An automatic turning mixer for thermosetting powder coatings is proposed, including a support frame and a mixing tank. The mixing tank is mounted on the support frame, and a limiting ring on the outer wall of the mixing tank is rotatably mounted on a bracket on the support frame. A first driver is provided on the support frame, and a first sprocket at the output end of the first driver meshes with a second sprocket on the outer wall of the mixing tank to drive the mixing tank to rotate. A second driver is provided on a cover sealed at the top of the mixing tank. The output end of the second driver extends into the interior of the mixing tank and is equipped with a connecting rod. Multiple first stirring blades are provided on the connecting rod. A feed inlet is provided on the side of the mixing tank near the cover, and a discharge outlet is provided at the bottom of the mixing tank. A disc is provided at the bottom of the connecting rod, and a second stirring blade is provided on the disc. The ends of the second stirring blades abut against the inner wall of the mixing tank, and a leakage port is formed between two second stirring blades.
[0005] In some embodiments, at least four first stirring blades are provided and are distributed in a circumferential array along the axis of the connecting rod.
[0006] In some embodiments, the first stirring blade has an arc-shaped structure, with its two ends welded to the connecting rod.
[0007] In some embodiments, the first stirring blade extends outward with an extension rod, and the end of the extension rod is provided with a scraper, which abuts against the inner wall of the mixing tank.
[0008] In some embodiments, at least two second stirring blades are provided and are distributed in a circumferential array around the axis of the connecting rod.
[0009] In some embodiments, the diameter of the disk is smaller than the diameter of the discharge port.
[0010] In some embodiments, the mixing tank rotates in the opposite direction to the stirring blades, and the stirring blades rotate at a faster rate than the mixing tank.
[0011] The technical solution provided in this application has the following advantages compared with the prior art:
[0012] The mixing tank of this utility model is erected on a support frame, with the discharge port located at the bottom. Raw materials are fed in from the side inlet. The mixing tank rotates under the action of the first driver, while the connecting rod rotates under the action of the second driver, causing the first stirring blade to rotate. This makes the mixing tank and the first stirring blade rotate together, thereby improving the efficiency of raw material mixing. The double rotation ensures that the raw materials are fully mixed.
[0013] Furthermore, the disc rotates with the connecting rod, thereby driving the second stirring blade to agitate the raw material located at the inlet, and the raw material passes through the discharge port and is discharged from the outlet, avoiding blockage caused by the slow flow and accumulation of raw material at the outlet.

[0022] like Figure 1-2 As shown, this utility model proposes an automatic tilting mixer for thermosetting powder coatings, including a support frame 1 and a mixing tank 2. The mixing tank 2 is mounted on the support frame 1. A limiting ring 3 on the outer wall of the mixing tank 2 is rotatably mounted on a bracket 4 on the support frame 1. The limiting ring 3 is welded to the mixing tank 2. The bottom of the mixing tank 2 is provided with a discharge port 5. The support frame 1 is provided with a first driver 6, which is a rotary motor. A first sprocket 7 at the output end of the first driver 6 is meshed with a second sprocket 8 on the outer wall of the mixing tank 2 to drive the mixing tank 2 to rotate. The second sprocket 8 is welded to the mixing tank 2.
[0023] The top of the mixing tank 2 is sealed with a cover and a second driver 9 is provided. The second driver 9 is a rotary motor. The mixing tank 2 is provided with a feed port 10 on the side near the cover. The output end of the second driver 9 extends into the mixing tank 2 and is equipped with a connecting rod 11. The connecting rod 11 is provided with a first stirring blade 12. There are at least four first stirring blades 12, which are arranged in a circumferential array around the axis of the connecting rod 11. The first stirring blades 12 have an arc-shaped structure and their two ends are welded to the connecting rod 11 to ensure the strength of the first stirring blades 12.
[0024] Furthermore, the first stirring blade 12 extends outward with an extension rod 13, and the end of the extension rod 13 is provided with a scraper 14. The scraper 14 abuts against the inner wall of the mixing tank 2. As the scraper 14 rotates with the first stirring blade 12, it scrapes the inner wall of the mixing tank 2, thereby preventing the raw materials from adhering to the inner wall.
[0025] In this embodiment, the mixing tank 2 is erected on the support frame 1, and the discharge port 5 is located at the bottom. The raw materials are fed in from the side inlet 10. The mixing tank 2 is rotated by the first driver 6, and at the same time, the connecting rod 11 is driven by the second driver 9 to drive the first stirring blade 12 to rotate, so that the mixing tank 2 and the first stirring blade 12 rotate together. The mixing tank 2 and the stirring blade rotate in opposite directions, and the rotation speed of the stirring blade is faster than the rotation speed of the mixing tank 2, thereby improving the efficiency of raw material mixing. The double rotation ensures that the raw materials are fully mixed.
[0026] Furthermore, a disc 15 is provided at the bottom of the connecting rod 11, and a second stirring blade 16 is provided on the disc 15. At least two second stirring blades 16 are provided and are arranged in a circumferential array around the axis of the connecting rod 11. The ends of the second stirring blades 16 abut against the inner wall of the mixing tank 2, and a material leakage port 17 is formed between the two second stirring blades 16.
[0027] In this embodiment, the diameter of the disc 15 is smaller than the diameter of the outlet 5. This structure ensures that the size of the formed discharge port 17 is sufficient to meet the discharge rate of the outlet 5. At the same time, the second stirring blade 16 will also become longer, thereby increasing the stirring range of the second stirring blade 16. The disc 15 will rotate with the connecting rod 11, thereby driving the second stirring blade to stir the raw material located at the inlet 10, and the raw material will pass through the discharge port 17 and then be discharged from the outlet 5, avoiding blockage caused by the slow flow and accumulation of raw material at the outlet 5.
[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
