Technical Field

[0001] This utility model relates to the field of tire vulcanizing devices, specifically a pipeline for real-time calibration of vulcanizing temperature. Background Technology

[0002] As is well known, temperature transmitters are widely used in the tire vulcanization process. This device can realize automatic temperature regulation and control, automatically save temperature data, and realize the automation of tire vulcanization. However, how to ensure that the temperature displayed by the device is always within the standard tolerance? The traditional approach is to periodically disassemble the temperature transmitter and send it to the laboratory for calibration. However, disassembly not only wastes manpower but also wastes steam due to pressure release, affecting production efficiency. Moreover, the vulcanization temperature directly affects product quality, posing a great risk to quality. Summary of the Invention

A temperature transmitter, a pipeline temperature measuring device, a second filter, a steam trap, and a fourth shut-off valve are connected in series, with its inlet connected to the lower heating plate of the vulcanizing machine and its outlet connected to the main condensate discharge pipeline. The pipeline temperature measuring device consists of a temperature measuring device housing, a temperature measuring device cover plate, and a temperature measuring device cover plate rotating shaft.

[0009] In the figure, this utility model includes a main steam inlet pipeline 1, a main condensate discharge pipeline 15, an upper hot plate of the vulcanizing machine 16, a mold sleeve 17, and a lower hot plate of the vulcanizing machine 18. A first filter 4, a regulating valve 5, and a third shut-off valve 6 are connected in series together and in parallel with a second shut-off valve 3 to form a steam inlet control and regulating pipeline and a bypass. These are connected in series with the first shut-off valve 2 and the main steam inlet branch pipeline 7 to form a hot plate steam inlet pipeline, which is connected to the main steam inlet pipeline 1. The upper hot plate of the vulcanizing machine 16, the mold sleeve 17, and the lower hot plate of the vulcanizing machine 18 are connected in series through a first metal hose 8 and a second metal hose 9. On the main steam inlet branch line 7, the temperature transmitter 10, the pipeline temperature measuring device 11 for real-time verification of vulcanization temperature, the second filter 12, the steam trap 13, and the fourth shut-off valve 14 are connected in series. The inlet is connected to the lower hot plate 18 of the vulcanizing machine, and the outlet is connected to the main condensate drain line 15, forming a hot plate and mold sleeve control pipeline loop. The pipeline temperature measuring device 11 for real-time verification of vulcanization temperature consists of a temperature measuring device housing 19, a temperature measuring device cover plate 20, and a temperature measuring device cover plate rotating shaft 21. The temperature measuring device cover plate 20 is hinged to the opening position of the temperature measuring device cover plate rotating shaft 21 via the temperature measuring device cover plate rotating shaft 21.

[0010] In this invention, the first shut-off valve 2 is open and the second shut-off valve 3 is closed. Steam enters the upper hot plate 16 of the vulcanizing machine through the main steam inlet pipeline 1, the first shut-off valve 2, the regulating valve 5, the third shut-off valve 6, and the main steam inlet branch pipeline 7. It then enters the mold sleeve 17 through the first metal hose 8, and then enters the lower hot plate 18 of the vulcanizing machine through the second metal hose 9. After passing through the hot plate, the steam exits through the temperature transmitter 10, the pipeline temperature measuring device 11, the second filter 12, the steam trap 13, and the fourth shut-off valve 14 before being discharged into the condensate drain pipeline 15. The control system operates automatically under PLC control. The cover plate 20 of the temperature measuring device can rotate around the rotating shaft 21 of the temperature measuring device cover plate to open and close the outlet of the pipeline temperature measuring device 11. When open, it facilitates the insertion of the surface thermometer to measure the temperature of the pipeline. When closed, it can insulate the pipeline and prevent heat loss.

[0011] This invention allows for real-time measurement of the pipeline temperature during vulcanization by inserting a surface thermometer into the pipeline temperature measuring device 11. This facilitates observation of whether the temperature is within the standard range. Simultaneously, comparing the temperature measured by the surface thermometer with the temperature displayed by the temperature transmitter verifies the accuracy of the temperature automatically measured by the temperature transmitter, providing strong temperature protection for tire vulcanization.
