[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-6 As shown, a cavity structure of a fully automatic coating machine includes:

[0028] Insulating outer shell 1 and inner shell 5;

[0029] The heat-conducting strips 4 are arranged in a circumferential array between the heat-insulating outer shell 1 and the inner shell 5, and the heat-conducting strips 4 include a first heat-conducting portion 41 and a second heat-conducting portion 42;

[0030] The heat conducting strip 4 is attached to the outer surface of the inner shell 5 , the first heat conducting portion 41 is arranged in a spiral shape, and the second heat conducting portion 42 is arranged in a helical shape.

[0031] Specifically, it also includes a condenser tube 3 located between the heat-insulating outer shell 1 and the inner shell 5. After the coating is completed, circulating cooling water is introduced into the condenser tube 3 through the water inlet 31 and the water outlet 32 ​​set on the condenser tube 3 to dissipate heat from the cavity. Figure 3 As shown, the condenser tube 3 is arranged around the inner shell 5, so as to achieve uniform cooling of the cavity.

[0032] Furthermore, since the thermally conductive strips 4 are attached to the outer surface of the inner shell 5 in a circular array, the thermally conductive strips 4 arranged in a circular array can uniformly conduct heat to the inner shell 5, and the heat is transferred to the cavity between the thermal insulation outer shell 1 and the inner shell 5 through the thermally conductive strips 4. The gas in the cavity exchanges heat with the condenser 3, and the cooling water circulating through the condenser 3 takes away the heat, thereby uniformly dissipating the heat to the inner shell 5 and the internal cavity of the inner shell 5, thereby preventing the inner shell 5 from deforming due to uneven heat dissipation, effectively extending the service life of the inner shell 5, and at the same time, improving the cooling effect and the coating quality.

[0033] Further, the heat conducting strip 4 is driven to rotate, such as Figure 6As shown, since the first heat conducting part 41 is arranged in a vortex shape and the second heat conducting part 42 is arranged in a spiral shape, when the heat conducting strip 4 rotates, the second heat conducting part 42 rotates to generate an oblique thrust on the air, so that the air between the heat-insulating outer shell 1 and the inner shell 5 rotates and flows along the inner wall of the heat-insulating outer shell 1 toward the first heat conducting part 41, so that the air between the heat-insulating outer shell 1 and the inner shell 5 rotates and flows and fully contacts with the condenser 3, thereby realizing rapid heat exchange and improving cooling efficiency.

[0034] In the above technology, since the heat-conducting strips 4 are attached to the outer surface of the inner shell 5 in a circumferential array, the heat-conducting strips 4 arranged in a circumferential array can evenly conduct heat to the inner shell 5, and the heat is transferred to the cavity between the heat-insulating outer shell 1 and the inner shell 5 through the heat-conducting strips 4, driving the heat-conducting strips 4 to rotate, such as Figure 6 As shown, since the first heat-conducting part 41 is arranged in a vortex shape and the second heat-conducting part 42 is arranged in a spiral shape, when the heat-conducting strip 4 rotates, the second heat-conducting part 42 rotates to generate an oblique thrust on the air, so that the air between the heat-insulating outer shell 1 and the inner shell 5 rotates and flows along the inner wall of the heat-insulating outer shell 1 toward the first heat-conducting part 41, thereby realizing rapid heat exchange. Compared with the prior art, rapid and uniform heat dissipation is achieved, the cooling efficiency and the coating quality are effectively improved, and at the same time, the service life of the cavity is extended.

[0035] As a further embodiment provided by the present invention, it also includes an air inlet 11 arranged on the heat-insulating shell 1 , and a filter screen 111 is arranged on the air inlet 11 .

[0036] Specifically, since the first heat conducting part 41 is arranged in a vortex shape and the second heat conducting part 42 is arranged in a spiral shape, when the heat conducting strip 4 rotates, the second heat conducting part 42 pushes the airflow to flow toward the first heat conducting part 41. At this time, under the push of the second heat conducting part 42, the air outside the heat-insulating outer shell 1 enters the cavity between the heat-insulating outer shell 1 and the inner shell 5 through the air inlet 11, thereby realizing heat exchange between air and air and heat exchange between the condenser tube 3 and air, thereby further accelerating the cooling efficiency and improving the cooling effect.

[0037] The filter screen 111 provided on the air inlet 11 prevents dust from entering.

[0038] As a further embodiment of the present invention, it also includes an air outlet 12 and an air inlet 13 arranged in a circumferential array on the inner shell 5, and valves are arranged on the air outlet 12 and the air inlet 13.

[0039] Specifically, after the coating is completed, the valves on the air outlet 12 and the air inlet 13 are opened. When the heat-conducting strip 4 rotates, the second heat-conducting portion 42 rotates to generate an oblique thrust on the air, so that the air between the heat-insulating outer shell 1 and the inner shell 5 rotates and flows along the inner wall of the heat-insulating outer shell 1 toward the first heat-conducting portion 41. Figure 1 and Figure 4As shown, since the first heat-conducting portion 41 is arranged in a vortex shape, the air flowing to the first heat-conducting portion 41 is compressed under the action of the first heat-conducting portion 41, thereby accelerating the airflow, and since the inner shell 5 is in a vacuum state, the accelerated airflow enters the inner shell 5 through the air inlet 13 of the inner shell 5, and enters between the thermal insulation outer shell 1 and the inner shell 5 again through the air outlet 12, thereby realizing the circulation of air inside the inner shell 5 and the cavity between the thermal insulation outer shell 1 and the inner shell 5, thereby quickly dissipating the heat of the parts and the inside of the inner shell 5, and further improving the heat dissipation efficiency.

[0040] As a further embodiment of the present invention, the heat-insulating outer shell 1 is hexagonal, the inner shell 5 is cylindrical, and the two are coaxial and the central axis is horizontal.

[0041] Specifically, it also includes a motor 2 fixed on the heat-insulating shell 1, and a rotating shaft 21 is fixedly arranged at the output end thereof, and a heat-conducting strip fixing frame 7 and a mounting column 6 are fixedly arranged on the rotating shaft 21, and the mounting column 6 is located at the central axis of the heat-insulating shell 1. The driving motor 2 rotates, thereby driving the rotating shaft 21 and the mounting column 6 to rotate, thereby driving the part rack to rotate, so as to uniformly coat the parts.

[0042] Since the heat-insulating outer shell 1 and the inner shell 5 are coaxial and the central axis is arranged horizontally, the mounting column 6 is located at the central axis of the heat-insulating outer shell 1, so the mounting column 6 is arranged horizontally. Figure 2 As shown, multiple parts racks can be mounted on the horizontally arranged mounting column 6, and the parts racks do not affect each other during coating, so that multiple groups of parts can be coated at the same time. Compared with the vertically arranged cavity, one cavity no longer corresponds to one parts rack, which not only improves the processing efficiency, but also saves the number of cavities, thereby saving equipment costs.

[0043] As a further embodiment provided by the present invention, the heat conducting strip fixing frame 7 is fixedly connected to the heat conducting strip 4 .

[0044] Specifically, by driving the motor 2 to rotate, the rotating shaft 21 and the heat conducting strip fixing frame 7 are driven to rotate, thereby driving the heat conducting strip 4 to rotate. No additional driving source is required to drive the heat conducting strip 4, thus simplifying the structure and saving manufacturing costs.

[0045] Working principle: The driving motor 2 rotates, thereby driving the rotating shaft 21 and the mounting column 6 to rotate, thereby driving the part rack to rotate, so as to uniformly coat the parts, and at the same time driving the heat conducting strip fixing frame 7 to rotate, thereby driving the heat conducting strip 4 to rotate. After the coating is completed, circulating cooling water is introduced into the condenser tube 3 through the water inlet 31 and the water outlet 32 ​​set on the condenser tube 3 to dissipate heat in the cavity. Figure 3As shown, the condenser 3 is arranged around the inner shell 5, so as to achieve uniform cooling of the cavity. Since the heat-conducting strips 4 are arranged in a circular array and fit the outer surface of the inner shell 5, the heat-conducting strips 4 arranged in a circular array can be used to uniformly conduct heat to the inner shell 5, and the heat is transferred to the cavity between the heat-insulating outer shell 1 and the inner shell 5 through the heat-conducting strips 4. The gas in the cavity exchanges heat with the condenser 3, and the cooling water circulating through the condenser 3 takes away the heat. The valves on the air outlet 12 and the air inlet 13 are opened. When the heat-conducting strips 4 rotate, the second heat-conducting part 42 rotates to generate an oblique thrust on the air, so that the air between the heat-insulating outer shell 1 and the inner shell 5 rotates and flows along the inner wall of the heat-insulating outer shell 1 to the first heat-conducting part 41, as shown in FIG. Figure 1 and Figure 4 As shown, since the first heat-conducting portion 41 is arranged in a vortex shape, the air flowing to the first heat-conducting portion 41 is compressed under the action of the first heat-conducting portion 41, thereby accelerating the airflow, and since the inner shell 5 is in a vacuum state, the accelerated airflow enters the inner shell 5 through the air inlet 13 of the inner shell 5, and enters between the thermal insulation outer shell 1 and the inner shell 5 again through the air outlet 12, thereby realizing the circulation of air inside the inner shell 5 and the cavity between the thermal insulation outer shell 1 and the inner shell 5, thereby quickly dissipating the heat of the parts and the inside of the inner shell 5, and further improving the heat dissipation efficiency.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
