Description

Technical Field

[0001] The invention relates to the technical field of array temperature measurement, in particular to an array temperature measurement system controlled by a PLC. Background Art

[0002] In tire vulcanization production, temperature, pressure and reaction time are crucial factors. The temperature during the vulcanization process directly affects the quality of the vulcanization reaction and is one of the important control conditions in the tire vulcanization process. Appropriate vulcanization temperature can improve the physical properties and durability of the tire, while shortening the vulcanization time and improving production efficiency. Existing temperature measurement of vulcanized tires usually uses pre-buried temperature measurement lines or fixed-point temperature sensors, which can usually only measure the temperature at a single position in the vulcanization module, and then use repeated tests to determine the location of the poor vulcanization reaction. It consumes a lot of resources, has a slow troubleshooting speed, and reduces the work efficiency of tire production.

[0003] For example, the patent document with the announcement number CN118392351B records a temperature measuring device for inner tube molds for tire production. When the mold is working, the outer temperature conducting rod and the inner temperature conducting rod are both located inside the temperature measuring hole. The heat inside the mold can be transferred through the outer temperature conducting rod and the inner temperature conducting rod. When it is necessary to measure the temperature at different positions of the mold, the drive motor is started to drive the screw to rotate to move the lifting plate downward, and the outer temperature conducting rod is pulled out from the inside of the temperature measuring hole. Then the electric telescopic rod is started to drive the inner temperature conducting rod to move downward and be pulled out from the inside of the anti-conducting hole. At this time, the inner temperature conducting rod is located on the side of multiple temperature sensors. Starting multiple temperature sensors can detect the temperature at different positions of the inner temperature conducting rod and obtain the temperature at different positions of the temperature measuring hole. Through the above setting, the temperature at different positions of the mold can be measured, which improves the accuracy of the mold temperature measurement. At the same time, it avoids the influence of the heat transfer inside the mold due to the temperature measurement of the opening, and improves the vulcanization molding effect of the tire. This temperature measuring device for inner tube molds for tire production can only perform temperature measurement inspection on a single position of the inner tube mold. The inspection range is small, and it is difficult to specifically detect the defective position of the inner tube mold, thereby reducing the tire production quality.

[0004] Based on this, a PLC-controlled array temperature measurement system is now provided to eliminate the drawbacks of existing devices. Summary of the invention
