[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The present invention provides a coating machine, including a casing 1 and a coating machine cavity 5. The upper surface of the coating machine cavity 5 is fixedly connected with a connecting pipe 4 fixedly connected to the top of the inner cavity of the casing 1. The lower surface of the casing 1 is provided with a plurality of air inlet holes 10. A motor 13 is installed in the middle of the lower surface of the casing 1. The output shaft of the motor 13 is transmission-connected with a rotating shaft 14. A fan 15 is installed at the upper end of the rotating shaft 14. A drainage air cavity 16 for air circulation is provided between the coating machine cavity 5 and the casing 1. A plurality of air outlet holes 6 are provided at the upper outer end of the casing 1. The fan 15 is used to generate airflow to accelerate the air circulation speed and perform air cooling and heat dissipation.

[0025] like Figure 4 As shown, a cooling water circulation device is installed on the coating machine described above, and also includes a water circulation mechanism 18 installed in the drainage air cavity 16 and a pre-cooling mechanism 19 installed in the inner cavity of the air inlet cylinder 11. The outer side of the coating machine cavity 5 is fixedly connected to multiple groups of heat sinks 8, and the multiple groups of heat sinks 8 are arranged at equal angles. The water circulation mechanism 18 is installed between the multiple groups of heat sinks 8. The heat sinks 8 accelerate the heat dissipation efficiency of the coating machine cavity 5, so that the water circulation mechanism 18 and the pre-cooling mechanism 19 cooperate to accelerate the temperature reduction, thereby improving the coating cooling efficiency of the jewelry.

[0026] In this embodiment, Figure 4 As shown, the water circulation mechanism 18 includes a circulating water pump 181 and a cooling coil 183. The circulating water pump 181 is installed on the other side of the water tank 17. The water outlet end of the circulating water pump 181 is connected to a water pipe 182. One end of the water pipe 182 is connected to one end of the cooling coil 183. The other end of the cooling coil 183 is connected to a first return water pipe 184 that passes through the casing 1. One end of the first return water pipe 184 is inserted into the upper surface of the water tank 17. The contact between the cooling coil 183 and the heat sink 8 is used to accelerate the cooling of the heat sink 8, thereby improving the heat dissipation efficiency of the coating machine cavity 5.

[0027] In this embodiment, Figure 2As shown, the upper surface of the casing 1 is fixedly connected with a connecting ring 2 connected to the connecting pipe 4, the outer side of the connecting ring 2 is threadedly connected to the organic cover 3, and the lower surface of the casing 1 is fixedly connected with an air inlet tube 11. The air inlet end of the air inlet tube 11 is provided with a filter 12. The inner diameter of the air inlet tube 11 is the same as the inner diameter of the connecting pipe 4. The connecting pipe 4 and the connecting ring 2 make it convenient to put the accessories into the coating machine cavity 5, and the filter 12 can prevent external dust from entering the drainage air cavity 16.

[0028] In a further preferred embodiment, Figure 2 As shown, multiple groups of support rods 9 are fixedly connected to the bottom of the inner cavity of the casing 1, and the upper ends of the multiple groups of support rods 9 are fixedly connected to the lower surface of the coating machine cavity 5. The multiple groups of support rods 9 are arranged at equal angles. The support rods 9 improve the stability of the coating machine cavity 5 and the overall stability of the device, thereby improving the service life of the casing 1.

[0029] Further, such as Figure 2 As shown, the upper end of the outer side of the casing 1 is fixedly connected with an air outlet pipe 7 connected to multiple groups of air outlet holes 6. The cross-section of each group of air outlet pipes 7 is L-shaped, and the long end of the air outlet pipe 7 is parallel to the outer side of the casing 1. The air outlet pipe 7 is used to discharge the air after heat exchange and blow air to the outer wall of the casing 1 to reduce dust adhesion on the outer wall of the casing 1, while cooling the outer wall of the casing 1 and improving the overall heat dissipation efficiency.

[0030] Preferably, Figure 1 As shown, multiple groups of connecting rods 23 are fixedly connected to the outer side of the casing 1, and the ends of the multiple groups of connecting rods 23 away from the casing 1 are fixedly connected to the water tank 17. Semiconductor refrigerators 20 are provided on both sides of the inner cavity of the water tank 17. The use of semiconductor refrigerators 20 can accelerate the cooling efficiency of the cooling water after heat exchange, thereby realizing the recycling efficiency of the cooling water.

[0031] In addition, if Figure 4 As shown, a water inlet pipe 21 is provided at the upper end of one side of the water tank 17, a drain pipe 22 with a valve is provided at the lower end of one side of the water tank 17, and a bracket 24 is fixedly connected to the lower surface of the casing 1. The cooling water can be conveniently replaced through the water inlet pipe 21 and the water outlet pipe. At the same time, the bracket 24 improves the overall stability of the device during coating.

[0032] In a further preferred embodiment, Figure 4As shown, the precooling mechanism 19 includes a precooling coil 192, which is arranged on the inner wall of the air inlet tube 11. The water inlet end of the precooling coil 192 is connected to a water distribution pipe 191, and the water distribution pipe 191 is fixedly connected to the outside of the water guide pipe 182. The water outlet end of the precooling coil 192 is connected to a second return water pipe 193, and one end of the second return water pipe 193 is plugged into the upper end of the other side of the water tank 17. The cooling water in the water guide pipe 182 is diverted through the water distribution pipe 191, so that the precooling coil 192 cools the air sucked into the casing 1, thereby improving the cooling efficiency of the coating machine cavity 5 and improving the efficiency of cooling the jewelry after coating.

[0033] Further, such as Figure 4 As shown, the cooling coil 183 is spirally wound around the outside of the coating machine cavity 5. The cooling coil 183 and multiple groups of heat sinks 8 are alternately arranged. The inner diameter of the cooling coil 183 is larger than the inner diameter of the pre-cooling coil 192. The air is pre-cooled first and then the cooling coil 183 and the heat sink 8 are dissipated, thereby improving the cooling efficiency of the coated accessories in the coating machine cavity 5.

[0034] When in use, the motor 13 drives the rotating shaft 14 to rotate the fan 15, thereby drawing the air outside the casing 1 into the air inlet 11, and preventing dust from entering through the filter 12. The water pump draws the cooling water in the water tank 17 to the water guide pipe 182, and the water guide pipe 182 divides the cooling water into the cooling coil 183 and the water distribution pipe 191. The water in the cooling coil 183 absorbs the heat on the heat sink 8 and the coating machine cavity 5 and then flows back to the water tank 17 through the first return pipe 184. At the same time, the water distribution pipe 191 passes the cooling water into the pre-cooling coil 192, and the pre-cooling coil 192 pre-cools the introduced air, thereby reducing the temperature of the air introduced into the drainage air cavity 16, improving the cooling effect of the cooling coil 183, and using a composite cooling method of water cooling and air cooling to cool the laminating machine cavity, thereby improving the cooling efficiency, and using the semiconductor refrigerator 20 to improve the cooling efficiency of the cooling water after heat exchange, thereby achieving the recycling efficiency of the cooling water, thereby reducing the cooling time of the coated product.
