In addition, the temperature monitoring device is movably installed inside the reserved docking interface of the heat exchanger, and the poor air tightness will also affect the final monitoring result.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-5 As shown, a coating machine heat exchanger temperature monitoring device comprises a pipeline 1, an internal thread connection port 2 is fixedly provided on the outside of the pipeline 1, and a temperature monitor 3 and an adjustable protective structure 4 are provided on the inside of the internal thread connection port 2;

[0026] The adjustable protective structure 4 includes an externally threaded connecting tube 5, which is movably arranged on the inner side of the internally threaded connecting port 2, and a protective tube 6 is slidably arranged on the inner side of the externally threaded connecting tube 5. A threaded rod 7 is rotatably arranged on one end of the externally threaded connecting tube 5, and a sliding rod 8 is fixedly arranged on the other end of the externally threaded connecting tube 5. One end of the threaded rod 7 and the sliding rod 8 respectively pass through the two ends of the protective tube 6.

[0027] The external threaded connecting pipe 5 is rotated and installed on the inner side of the internal threaded connecting port 2. According to the bottom length of the temperature monitor 3 and the diameter of the pipeline 1, the threaded rod 7 is rotated and adjusted. The threaded rod 7 acts on the protective tube 6, so that the protective tube 6 slides vertically inside the external threaded connecting pipe 5. During the process, the two ends of the protective tube 6 slide outside the threaded rod 7 and the sliding rod 8 respectively. When the protective tube 6 reaches the required height, the threaded rod 7 is stopped from rotating. The bottom of the temperature monitor 3 is passed through the inner side of the protective tube 6 and the external threaded connecting pipe 5 and inserted into the inner side of the pipeline 1 to complete the work of adjusting the protection.

[0028] In this embodiment, the bottom of the temperature monitor 3 penetrates through the inner sides of the protective tube 6 and the external threaded connecting tube 5 and is movably arranged on the inner side of the pipeline 1 , and the temperature monitor 3 is adaptably matched with the external threaded connecting tube 5 , the protective tube 6 and the pipeline 1 .

[0029] The external threaded connecting pipe 5 cooperates with the protective pipe 6 to adjust the working height.

[0030] In this embodiment, the threads of the externally threaded connecting pipe 5 and the internally threaded connecting port 2 are adaptively matched, and the protective pipe 6 and the externally threaded connecting pipe 5 are adaptively matched.

[0031] The external thread of the external thread connection pipe 5 cooperates with the internal thread of the internal thread connection port 2 so that the external thread connection pipe 5 can be rotatably connected to the outside of the pipeline 1 .

[0032] In this embodiment, the protective tube 6 and the threaded rod 7 are adaptively matched, and the protective tube 6 and the sliding rod 8 are adaptively matched.

[0033] The threaded rod 7 can enable the protection tube 6 to perform vertical sliding movement inside the external threaded connection tube 5 .

[0034] In this embodiment, a fastening structure 9 is provided on the outside of the protective tube 6 and the outside of the temperature monitor 3. The fastening structure 9 includes two connecting plates 10. The two connecting plates 10 are symmetrically arranged on both sides of the rear part of the protective tube 6. A bidirectional screw rod 11 is rotatably arranged between the two connecting plates 10. Two limit clamps 12 are symmetrically slidably arranged on the outside of the bidirectional screw rod 11.

[0035] When the bottom of the temperature monitor 3 is inserted into the interior of the pipeline 1, the external fixed tube 13 of the temperature monitor 3 is completely inserted into the inner side of the protective tube 6. The bidirectional screw rod 11 is manually rotated to make the limiting clamp plate 12 slide outside the bidirectional screw rod 11. When the limiting clamp plate 12 is completely in contact with the top reserved groove of the fixed tube 13, the temperature monitor 3 can be completely fixed. During the process, the limiting clamp plate 12 acts on the fixed tube 13, so that the inner top surface of the bottom of the fixed tube 13 is pressed against the spring 15, and then the spring 15 acts on the air cushion 14, and finally the air cushion 14 is closely fitted to the inner bottom surface of the protective tube 6, so that the overall air tightness is enhanced, which is conducive to improving the accuracy of temperature monitoring.

[0036] In this embodiment, a fixed tube 13 is fixedly provided on the outside of the temperature monitor 3 , an air cushion 14 is slidably provided on the bottom of the fixed tube 13 , and a plurality of springs 15 are evenly provided between the top of the air cushion 14 and the inner top surface of the bottom of the fixed tube 13 .

[0037] The air cushion 14 enhances the air tightness, and the spring 15 enables the air cushion 14 to fit tightly with the inner bottom surface of the protection tube 6 .

[0038] In this embodiment, the two limit clamping plates 12 are both adaptable to the fixing tube 13 , the fixing tube 13 is adaptable to the protection tube 6 , and the air cushion 14 is adaptable to the protection tube 6 .

[0039] The limiting clamping plate 12 allows the temperature monitor 3 to be firmly fixed.

[0040] It should be noted that the utility model is a temperature monitoring device for a heat exchanger of a coating machine. When in use, it is placed at a site where it needs to work, so that it can reach the operating conditions of the work;

[0041] During the process, the external threaded connection pipe 5 is rotated and installed on the inner side of the internal threaded connection port 2. According to the bottom length of the temperature monitor 3 and the diameter of the pipeline 1, the threaded rod 7 is rotated and adjusted. The threaded rod 7 acts on the protection pipe 6, so that the protection pipe 6 slides vertically inside the external threaded connection pipe 5. During the process, the two ends of the protection pipe 6 slide outside the threaded rod 7 and the sliding rod 8 respectively. When the protection pipe 6 reaches the required height, the threaded rod 7 is stopped from rotating. The bottom of the temperature monitor 3 is passed through the inner side of the protection pipe 6 and the external threaded connection pipe 5 and inserted into the inner side of the pipeline 1, and the work of adjusting the protection can be completed.

[0042] During the process, after the bottom of the temperature monitor 3 is inserted into the interior of the pipeline 1, the external fixed tube 13 of the temperature monitor 3 is completely inserted into the inner side of the protective tube 6, and the bidirectional screw rod 11 is manually rotated to make the limiting clamp plate 12 slide on the outside of the bidirectional screw rod 11. When the limiting clamp plate 12 is completely in contact with the top reserved groove of the fixed tube 13, the temperature monitor 3 can be completely fixed. During the process, the limiting clamp plate 12 acts on the fixed tube 13, so that the inner top surface of the bottom of the fixed tube 13 is pressed against the spring 15, and then the spring 15 acts on the air cushion 14, and finally the air cushion 14 is tightly fitted to the inner bottom surface of the protective tube 6, so that the overall air tightness is enhanced, which is conducive to improving the accuracy of temperature monitoring.
