Description

Technical Field

[0001] This utility model relates to the field of coating mixing technology, and in particular to a high-efficiency mixing device for thin-film powder coatings. Background Technology

[0002] Thin-film powder coatings are a type of powder coating with a relatively thin thickness, typically used for surface decoration and corrosion protection. They possess high surface hardness, abrasion resistance, weather resistance, and corrosion resistance, making them suitable for various metal surfaces such as aluminum and steel. They are widely used in industries such as construction, automotive, and home appliances. Thin-film powder coatings typically produce thin, smooth, and uniform films with high adhesion. The production and processing of thin-film powder coatings requires the mixing of the coating raw materials.

[0003] The raw material mixing equipment for powder coating production disclosed in announcement number CN214598765U solves the problem of raw material powder easily entering the rotating shaft by setting a dust cover. This avoids the raw material powder accumulating in the rotating shaft over a long period of time, which would affect the rotation effect of the rotating shaft, thus ensuring the smoothness and flexibility of the rotating shaft during rotation and improving the service life of the rotating shaft.

[0004] However, the raw material mixing equipment used for powder coating production has the following disadvantages: it is not convenient to mix powder coatings in multiple dimensions, the powder coatings in the upper and lower layers are not easy to exchange with each other, and some larger powder coating particles are not easy to break, which affects the mixing effect and the quality of powder coatings.

[0017] 1. This high-efficiency mixing equipment for thin-film powder coatings utilizes a tilting mechanism, a mixing mechanism, and a shearing mechanism. The tilting mechanism drives the mixing drum to tilt, generating a combined effect of centrifugal force and gravity, causing the thin-film powder coating to scatter within the drum. The mixing mechanism forces the powder coating to the shearing mechanism, while a drum wall scraper prevents the powder coating from adhering to the inner wall of the mixing drum.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a high-efficiency mixing device for thin-film powder coatings, including a fixed base 1, and a shock-absorbing mechanism 2 fixedly installed on the top surface of the fixed base 1. Through the setting of the shock-absorbing mechanism 2, during the mixing of thin-film powder coatings, the mounting plate 3 will squeeze the shock-absorbing mechanism 2, the shock-absorbing spring 201 will absorb the vibration force, and the damper 202 will consume the energy stored in the shock-absorbing spring 201, thereby achieving the effect of shock absorption during the mixing of thin-film powder coatings, improving the stability of the equipment and reducing operating noise;

[0027] A mounting plate 3 is fixedly installed on the top of the shock absorption mechanism 2. A support frame 4 is fixedly installed on one side of the top surface of the mounting plate 3. A tilting mechanism 5 is fixedly installed on one side of the support frame 4. A mixing tank 6 is fixedly installed on one side of the tilting mechanism 5. A tank cover 7 is fixedly installed on the top of the mixing tank 6. A mixing mechanism 8 is fixedly installed on the top surface of the tank cover 7. A shearing mechanism 9 is fixedly installed on the bottom surface of the mixing tank 6. Through the setting of the tilting mechanism 5, the mixing mechanism 8, and the shearing mechanism 9, the tilting mechanism 5 is used to drive the mixing tank 6 to tilt as a whole. Tilting can generate a combined effect of centrifugal force and gravity, so that the thin-coat powder coating forms a throwing motion in the tank. The mixing mechanism 8 forces the powder coating to be transported to the shearing mechanism 9. The tank wall scraper 803 prevents the powder coating from adhering to the inner wall of the mixing tank 6. The shearing mechanism 9 shears and crushes the powder coating, further refining the coating and avoiding the existence of large pieces of coating. The whole forms a three-dimensional mixing network, reducing mixing dead corners, ensuring thorough mixing, strong function, and high efficiency.

[0028] The damping mechanism 2 includes a damping spring 201 and a damper 202. The damping spring 201 is fixedly installed on the top surface of the fixed base 1, and the damper 202 is sleeved inside the damping spring 201. The bottom of the damper 202 is fixedly installed on the top surface of the fixed base 1. Both the damping spring 201 and the damper 202 are fixedly connected to the mounting plate 3.

[0029] The damping mechanism 2 serves to reduce vibration during the mixing of thin-film powder coatings.

[0030] The flipping mechanism 5 includes an A servo motor 501, a large gear 502, and a small gear 503. The A servo motor 501 is fixedly installed on one side of the support frame 4. The large gear 502 is fixedly installed at the output end of the A servo motor 501. The bottom of the small gear 503 meshes with the large gear 502. The small gear 503 is rotatably connected to the support frame 4.

[0031] With the setting of the flipping mechanism 5, after the A servo motor 501 is powered on, it drives the large gear 502 to rotate, which in turn drives the small gear 503 to rotate, so that the mixing bucket 6 rotates accordingly. The flipping can generate a combination of centrifugal force and gravity, so that the thin-coat powder coating forms a throwing motion in the bucket.

[0032] The mixing mechanism 8 includes a B servo motor 801, an auger rod 802, and a barrel wall scraper 803. The B servo motor 801 is fixedly installed on the top surface of the barrel cover 7. The auger rod 802 is fixedly installed at the output end of the B servo motor 801. The barrel wall scraper 803 consists of two sets and is symmetrically arranged on the top of the auger rod 802.

[0033] With the mixing mechanism 8 in place, the B servo motor 801 drives the auger rod 802 and the barrel wall scraper 803 to rotate. The auger rod 802 forces the powder coating to the shearing mechanism 9 for shearing and crushing, while the barrel wall scraper 803 prevents the powder coating from adhering to the inner wall of the mixing barrel 6.

[0034] The shearing mechanism 9 includes a C servo motor 901 and a shearing blade 902. The C servo motor 901 is fixedly installed on the bottom surface of the mixing tank 6, and the shearing blade 902 is fixedly installed at the output end of the C servo motor 901.

[0035] With the shearing mechanism 9 in place, the C servo motor 901 drives the shearing blade 902 to rotate, thereby shearing and crushing the powder coating.

[0036] A material inlet 10 is fixedly provided on one side of the bottom surface of the mixing tank 6, and a sealing cover 11 is threadedly connected to the surface of the material inlet 10.

[0037] The feed inlet 10 serves to allow thin-film powder coatings to enter and exit, while the sealing cap 11 is used to open or close the feed inlet 10.

[0038] There are four sets of damping mechanisms 2, which are arranged in a rectangular array.

[0039] The damping mechanism 2 is designed to dampen the vibration of the equipment.

[0040] In this invention, the working steps of the device are as follows:

[0041] First step: After the A servo motor 501 is powered on, it drives the large gear 502 to rotate, which in turn drives the small gear 503 to rotate, causing the mixing bucket 6 to rotate and flip, generating a combined effect of centrifugal force and gravity, causing the thin-film powder coating to form a throwing motion inside the bucket.

[0042] Second step: B ​​servo motor 801 drives the auger rod 802 and the barrel wall scraper 803 to rotate. The auger rod 802 forces the powder coating to the shearing mechanism 9 for shearing and crushing. The barrel wall scraper 803 prevents the powder coating from adhering to the inner wall of the mixing barrel 6. C servo motor 901 drives the shearing blade 902 to rotate, shearing and crushing the powder coating.

[0043] The third step: During the mixing of thin-film powder coating, the mounting plate 3 will squeeze the damping mechanism 2, the damping spring 201 will absorb the vibration force, and the damper 202 will consume the energy stored in the damping spring 201, thus achieving the effect of damping when mixing thin-film powder coating, improving the stability of the equipment and reducing operating noise.
