[0026] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 as well as Figure 8 ,in, Figure 1 This is a schematic diagram of the overall structure of the ink constant temperature system device for a printing press provided by the utility model; Figure 2 A schematic diagram of the combined structure of the heating device and the air cooling device provided by the utility model; Figure 3 A schematic diagram of the combined structure of the cooling plate and the fan provided by the present invention; Figure 4 This is a schematic diagram of the disassembled structure of the cooling plate and ink flow tube provided by the utility model; Figure 5 A schematic diagram of the overall structure of the cooling plate provided by the utility model; Figure 6 A schematic diagram of a partial cross-sectional structure of a cooling plate provided by the present invention; Figure 7 A schematic diagram of the structure of the fan provided by the utility model; Figure 8 This is a structural schematic diagram of the heating device provided by the utility model.

[0028] In the specific implementation process, Figures 1-8 As shown, the ink constant temperature system device of the printing press includes a housing 1 and a heating device and an air cooling device located inside the housing 1. The air cooling device includes an ink circulation tube 2 and a plurality of interconnected cooling plates 3. The plurality of cooling plates 3 are fixedly mounted on the bottom wall of the housing 1. A plurality of interconnected air vents 4 are arranged in an array on one side of the plurality of cooling plates 3 facing the opposite side thereof, and a plurality of air vents 5 are arranged in an array on the top of the plurality of cooling plates 3 facing the bottom thereof, which are connected to the inner cavity of the air vents 4. One end of the ink circulation tube 2 is formed in an "S" shape and passes through the plurality of air vents 4 located on the bottom layer in sequence. The ink circulation tube 2 is provided with an ink inlet 6 and an ink outlet 7 at both ends thereof, respectively.

[0029] The "S"-shaped design increases the length of the ink line and the surface area in contact with the outside air, which helps improve heat exchange efficiency. Multiple air vents ensure that the airflow through the ink tube can effectively remove heat, avoiding local overheating, which is more effective for equipment running for a long time.

[0030] The plurality of air vents 1 4 and the plurality of air vents 2 5 increase the complexity of the air circulation path, making the air flow more uniform and increasing the heat exchange area, thereby improving the cooling efficiency. In addition, the heating and cooling are set separately to avoid the influence of the constant temperature processing efficiency caused by the simultaneous operation of cooling.

[0031] Air outlet slots 17 are provided on both sides of the housing 1, and the cooling plates 3 at the head and tail ends of the plurality of cooling plates 3 are located in the air outlet slots 17;

[0032] It should be noted that the cooling plate 3 can be a zinc-copper alloy plate or a copper-aluminum alloy plate or other plates with good thermal conductivity.

[0033] Fans are provided on the tops of the cooling plates 3 , and the air outlet ends of the fans are directly above the air vents 2 5 .

[0034] In a specific embodiment, the heating device includes a shell 8 and multiple electric heating tubes 9. The shell 8 is fixedly installed on the top wall of the casing 1, and the multiple electric heating tubes 9 are respectively fixedly installed on the bottom of the shell 8. A power supply 18 for supplying power to the electric heating tubes 9 is also provided on one side of the shell 8. Heat is supplied by electric heating. When heating, the fan is turned off, so that the hot air passes through the multiple air vents 2 5 into the multiple air vents 1 4 and contacts the surface of the "S"-shaped ink circulation tube 2, and the ink circulation tube 2 absorbs heat.

[0035] It should be noted that the multiple cooling plates 3 are spliced ​​together in the following manner: multiple dovetail blocks 10 and dovetail grooves 11 are provided on the edge of the cooling plate 3, and two adjacent cooling plates 3 are engaged with each other through the dovetail blocks 10 and the dovetail grooves 11, which can be adjusted according to the different lengths of the ink circulation tubes 2.

[0036] In one embodiment, the fan includes a housing 12, a bracket 13, a rotary drive member 14, a shaft 15, and a plurality of fan blades 16 arranged around the surface of the shaft 15. The housing 12 is fixedly mounted on the top of the cooling plate 3, and a connecting groove is formed on both sides of the housing 12. The bracket 13 is fixedly mounted in the connecting groove of the housing 12. The rotary drive member 14 is fixedly mounted on the bracket 13, and the output end of the rotary drive member 14 is fixedly connected to one end of the shaft 15.

[0037] It should be noted that the rotating drive member 14 is a motor, the rotor end of the motor is fixed to one end of the shaft 15, and the motor drives the shaft 15 to rotate, thereby causing the multiple fan blades 16 to rotate and accelerate the air circulation rate inside the housing 1.

[0038] The working principle provided by the present invention is as follows: when the device is in use, two adjacent cooling plates 3 are engaged with each other through the dovetail block 10 and the dovetail groove 11, which can be adjusted according to the different lengths of the ink circulation tube 2, and heat is supplied by electric heating. When supplying heat, the fan is closed, so that the hot air passes through the multiple air vents 2 5 and enters the multiple air vents 1 4 and contacts the surface of the "S"-shaped ink circulation tube 2, and the ink circulation tube 2 absorbs heat. The motor drives the shaft 15 to rotate, and then the multiple fan blades 16 rotate accordingly to accelerate the air circulation rate inside the casing 1. The multiple air vents 1 4 and the multiple air vents 2 5 increase the complexity of the air circulation path, making the air flow more uniform and increasing the heat exchange area, thereby improving the cooling efficiency.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
