Description

[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to evaporate and condense them on the surface of the coated part to form a thin film. This method uses vacuum technology to avoid the interference of impurities in the air on the coating process, ensure the purity and uniformity of the film layer, and make vacuum coating have broad application prospects and significant technical advantages. Vacuum coating can avoid the interference of impurities in the air on the coating process, ensure the purity and uniformity of the film layer, and have good adhesion strength.

[0003] During the vacuum coating process, heating can cause the coating material to evaporate and convert into gas.

[0048] Specifically, in this embodiment, the first gear 221 and the second gear 231 are meshed with each other, so that when the motor 21 works to rotate the first rotating rod 22, the first gear 221 is installed on the outside of the first rotating rod 22, so this will also cause the first gear 221 to rotate to rotate the second gear 231, and then drive the second rotating rod 23 to rotate. During rotation, the stirring rod 24 outside the first rotating rod 22 and the second rotating rod 23 can stir and turbulently disturb the incoming air, thereby achieving the purpose of efficiently mixing the air.

[0049] The preferred embodiment of the present invention is as follows: the air inlet end of the air extraction pump 53 is connected with an air inlet pipe, one end of the air inlet pipe passes through the outer side of the preheating mixing box 2 and extends to the interior of the preheating mixing box 2, one end of the heat conduction pipe 52 also passes through the outer side of the preheating mixing box 2 and extends to the interior of the preheating mixing box 2, one end of the heat conduction pipe 52 is connected with a fixed pipe 54 inside the heat conduction box 5, a connecting pipe 541 is arranged on the outer side of the fixed pipe 54, and the air outlet end of the air extraction pump 53 is connected with one end of the connecting pipe 541.

[0050] Specifically, in this embodiment, the regulated air inside the preheating mixing box 2 can be extracted through the pipeline through the operation of the vacuum pump 53, and after being extracted, it enters the interior of the heat conduction pipe 52 through the connecting pipe 541 and the fixed pipe 54. After entering the interior of the heat conduction pipe 52, its temperature will be conducted through the heat conduction plate 51, and then the vacuum coating material can be preheated by the heat of the heat conduction.

[0051] The working principle of the present invention is as follows: when the controllable vacuum coating preheating system of the present invention is used, the heating tube 341 inside the heating box 3 is first heated by energizing, and after heating, the exhaust fan 32 inside the heating box 3 is started to work, so that the external air can be drawn and enter the interior of the heating box 3 through the air inlet 31. After entering, the air will contact with the energized heating tube 341 to achieve heating, and after heating, it will enter the interior of the preheating mixing box 2 through the exhaust pipe 33. The interior of the preheating mixing box 2 is provided with a temperature sensor, and the temperature inside the preheating mixing box 2 can be monitored by the temperature sensor. In addition, the exhaust pipe 33 is provided with an electric valve to achieve the purpose of automatic opening and closing.

[0052] When the hot air enters the preheating mixing box 2 and the temperature is high and needs to be regulated, the liquid extraction pump 43 in the cooling box 4 is started to extract the coolant inside and enter the circulation pipe 431. The circulation pipe 431 is arranged inside the preheating mixing box 2. After the coolant enters the circulation pipe 431, the cold air will dissipate heat outward and contact the hot air inside the preheating mixing box 2, so as to achieve the purpose of regulating the temperature. It should be noted that the end of the circulation pipe 431 is arranged inside the cooling box 4, so that the purpose of circulating the coolant can be achieved.

[0053] When the temperature inside the preheating mixing box 2 meets the preheating temperature of the vacuum coating material, the electric valve outside the pipe running through the preheating mixing box 2 is opened, and the vacuum pump 53 is started, so that the air inside the preheating mixing box 2 can be passed into the connecting pipe 541 and the fixed pipe 54 to enter the interior of the heat conduction pipe 52. After entering the interior of the heat conduction pipe 52, its temperature will be transferred through the heat conduction plate 51, and then the vacuum coating material can be preheated by the heat of the heat conduction. The other end of the heat conduction pipe 52 also runs through the interior of the preheating mixing box 2 to achieve the purpose of exhaust.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
