Description

Technical Field

[0001] The utility model belongs to the technical field of powder coating cooling, in particular to cooling equipment for preparing metal powder coating. Background Art

[0002] Metallic powder coatings create a bright, luxurious decorative effect, making them ideal for spraying on indoor and outdoor surfaces such as furniture, accessories, and automobiles. Dry mixing is currently the primary manufacturing method used in the domestic market, while adhesive bonding is also used internationally. The production of metallic powder coatings requires a cooling device, but existing cooling systems typically rely on natural cooling or wind power after storage, which cannot achieve uniform cooling.

[0003] Publication number CN219624340U describes a cooling device for preparing metal powder coatings. This device features a flip mechanism. When the motor is turned on, it drives the rotating shaft, stirring blades, and flip mechanism to rotate. Multiple stirring blades stir the metal powder horizontally, while the flip mechanism stirs the bottom metal powder vertically. The bottom metal powder is flipped upward, and then the entire metal powder moves downward under gravity. During this continuous vertical stirring process, the bottom metal powder gradually exchanges positions with the outer metal powder, increasing the contact area between the bottom metal powder and the air, accelerating heat dissipation, and reducing uneven cooling of the metal powder. However, there is still room for improvement in cooling efficiency and heat dissipation uniformity. Utility Model Content

[0018] The adaptable design of multiple sets of suction cylinders and suction plates, as well as the connection between the drainage arc plate and the suction cylinder, is achieved through the threaded connection between the threaded rod and the suction plate, and the meshing design between the drive gear and the transmission gear, in conjunction with the connection design between the drive motor and the drive gear.

The top of the inner cylinder 2 is connected with a feed port 3, and the bottom of the inner cylinder 2 is connected with a discharge pipe 4. The discharge pipe 4 passes through the outer cylinder 1 for easy discharge. Automatic valves are provided on the inner periphery of the discharge pipe 4 and the feed port 3.

[0033] See also Figure 1 and Figure 2 In order to realize the overturning of the powder coating, a central cylinder 6 is installed at the bottom center of the inner cylinder 2. Inlet ports are opened on the four sides of the bottom of the central cylinder 6. A central rod 7 is set at the center of the inner periphery of the central cylinder 6. The outer periphery of the central rod 7 is connected to a spiral piece 8. The outer periphery of the spiral piece 8 is adapted to the inner periphery of the central cylinder 6.

[0034] The top end of the center rod 7 is rotatably connected to the top of the inner cylinder 2. A rotary motor 9 is installed at the top center of the inner cylinder 2. The driving end of the rotary motor 9 passes through the inner cylinder 2 and is connected to the top end of the center rod 7 through a coupling.

[0035] When the rotary motor 9 is running, it drives the central rod 7 to rotate, causing the spiral piece 8 to rotate, which can twist and send the powder coating at the bottom from bottom to top to achieve overturning.

[0036] See also Figure 2 and Figure 4 In order to achieve wind cooling, a filter plate 10 is installed in the top inner cavity of the inner cylinder 2. The bottom of the filter plate 10 is rotatably connected to a vortex fan 11. The vortex fan 11 consists of a circular fan shell and multiple inclined vortex blades. The outer periphery of the fan shell is rotatably connected to the bottom of the filter plate 10 through a shaft ring.

The inner ring of the ring gear 22 is connected to the outer ring of the fan casing. Therefore, when the center rod 7 rotates, it can drive the ring gear 22 and the vortex fan blades to rotate, thereby attracting wind force. Combined with the overturning design, uniform cooling can be achieved.

[0038] See also Figure 2 and Figure 3In order to achieve cooling, a plurality of suction cylinders 12 are installed on the inner wall of the outer cylinder 1. A drainage arc plate 14 is provided on one side of the suction cylinder 12. The drainage arc plate 14 is in an arc shape. The interior of the drainage arc plate 14 is hollow and a plurality of nozzles are provided on the side close to the inner cylinder 2. The drainage arc plate 14 is connected to the suction cylinder 12.

[0039] The suction cylinder 12 is also in an arc shape that matches the outer cylinder 1. One side of the suction cylinder 12 is connected to a suction pipe 15 immersed in the coolant. A one-way valve is provided at the end connection of the suction pipe 15. The design of the one-way valve allows the coolant to only enter the interior of the suction cylinder 12. A suction plate 13 is adapted to be provided on the inner periphery of the suction cylinder 12, and a rubber layer is bonded to the outer periphery of the suction plate 13.

[0040] A threaded rod 33 is threadedly connected to the center of the suction plate 13.

A drive motor 34 is installed at the bottom center of the outer cylinder 1. The driving end of the drive motor 34 passes through the outer cylinder 1 and is connected to the drive gear 31 through a coupling. The outer periphery of the drive gear 31 is meshed with a transmission gear 32. The center of the transmission gear 32 is connected to the outer periphery of the threaded rod 33.

[0041] When the driving motor 34 is running, it drives the driving gear 31 to rotate back and forth, causing the transmission gear 32 to rotate, causing the threaded rod 33 to rotate, further causing the suction plate 13 to rise and fall back and forth, achieving suction, and then spraying the liquid to the outer periphery of the inner tube 2 through the discharge arc plate 14;

[0042] In order to improve the cooling effect, a plurality of cooling rods 5 are connected to the inner wall of the inner tube 2. The cooling rods 5 are made of copper. The temperature of the sprayed coolant will be effectively absorbed by the cooling rods 5, thereby improving the cooling effect.

[0043] The above components and electrical equipment are all existing technologies or existing feasible technologies. Their working principles, sizes and models are irrelevant to the functions of this application, so they will not be described in detail. They are all controlled by remote control switches.

[0044] How it works

[0045] When the cooling device for preparing metal powder coating is used, the metal powder coating is fed into the inner cylinder 2 through the feed port 3, and the rotary motor 9 is started to drive the central rod 7 to rotate, causing the spiral blades 8 to rotate, so that the powder coating at the bottom is twisted and sent to the top, thereby realizing twisting from bottom to top;

[0046] At the same time, the rotation of the center rod 7 drives the vortex fan 11 to rotate, so that the external wind blows the overturned powder coating inside to achieve cooling;

[0047] At the same time, the drive motor 34 is started to run forward and reverse, driving the drive gear 31 to rotate, causing the transmission gear 32 to rotate, causing the threaded rod 33 to rotate back and forth, further driving the suction plate 13 to rise and fall back and forth, sucking the cooling water, and then spraying it to the outer periphery of the inner tube 2 through the discharge arc plate 14, further improving the cooling effect.
