Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vulcanizing machine technology, specifically relating to a cooling device for a tire vulcanizing machine motor. Background Technology
[0002] Currently, the heating method of tire vulcanizing machines is mainly developing towards electric heating, using electricity to heat the medium inside the vulcanizing bladder. Tire vulcanizing machines are also equipped with agitating devices such as fans and impellers, driven by a rotating motor to agitate the medium, causing it to flow and distribute heat evenly, improving heating uniformity and providing the heat required for vulcanization.
[0003] In tire vulcanization production, the motor is usually installed in the pit. In order to ensure that the medium inside the capsule does not leak out, a magnetic coupling is often used to drive the rotating shaft. At the same time, it can isolate the inside from the outside. Since the rotating shaft is a driven shaft and is sealed inside, it is impossible to detect whether the rotating shaft is rotating by traditional methods, and the speed information cannot be obtained. Once it loses rotation or stops, the impeller cannot stir the medium, and high temperature will appear near the heater, resulting in abnormal tire vulcanization. Utility Model Content

[0053] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0054] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0055] Example 1
[0056] Please refer to Figure 1 , Figure 2 , Figure 9 This utility model provides a tire vulcanizing machine motor detection device, which can detect the rotational speed of the tire vulcanizing machine motor. Figure 9 The image shows a tire vulcanizing machine. The vulcanizing bladder is filled with a high-pressure medium, such as nitrogen. An electric heater heats the medium, and an impeller and other air outlet components are included. The rotation of the impeller agitates the medium inside the bladder, ensuring it fills the vulcanizing bladder evenly and preventing localized overheating or underheating, thus providing uniform heating of the tire. The impeller rotation requires a motor, which can directly drive the impeller or drive it via gears or other transmission methods. Maintaining a tight seal during impeller rotation due to the high temperature and pressure of the medium inside the bladder is difficult. To prevent leakage, a magnetic coupling is often used to drive the rotating shaft, simultaneously isolating the internal components from the external environment. Since the magnetic coupling and the impeller drive shaft are driven shafts and sealed internally, the driven shaft is directly or indirectly connected to the impeller. By detecting the rotational speed of the driven shaft, the machine determines whether the impeller is rotating, adjusting the heater power or switching it on / off accordingly.
[0057] This utility model provides a detection device for a tire vulcanizing machine motor, comprising: a drive shaft 1, disposed outside a transmission housing 5, suitable for connection to the output shaft of a drive component; a driven shaft 3, disposed inside the transmission housing 5, suitable for driving a rotating component to rotate; a drive shaft magnet seat 11 is disposed at the end of the drive shaft 1 facing the driven shaft 3; a driven shaft magnet seat 31 is disposed at the end of the driven shaft 3 facing the drive shaft 1; the drive component drives the driven shaft 3 to rotate via a magnetic component; the magnetic component includes a first magnetic body 12 and a second magnetic body 32, the first magnetic body... The first magnetic body 12 is mounted on the drive shaft magnet seat 11, and the second magnetic body 32 is mounted on the driven shaft magnet seat 31. The first magnetic body 12 and the second magnetic body 32 are correspondingly arranged. The sealing cover 2 is mounted on the transmission box 5 and protrudes outward toward the transmission box 5. The driven shaft magnet seat 31 extends into the sealing cover 2 and is located between the drive shaft magnet seat 11 and the driven shaft magnet seat 31, separating the drive shaft 1 and the driven shaft 3 and sealing the inner and outer spaces of the transmission box 5. Furthermore, it also includes a detection device suitable for detecting the rotational speed of the driven shaft 3.
[0058] Specifically, in this embodiment, the first magnetic body 12 is disposed on the end face of the active shaft magnet seat 11, and the second magnetic body 32 is disposed on the end face of the driven shaft magnet seat 31, and the two are arranged along the axial direction of the active shaft 1.
[0059] Please refer to Figure 2 The detection device includes an induction coil 41, which is laid flat on the lower end face of the outer side of the sealing cover 2. The induction coil 41 is ring-shaped and corresponds to the second magnetic body 32 in the radial direction of the driven shaft 3. Here, the first magnetic body 12 and the second magnetic body 32 attract each other and the attraction force is the greatest. When the driving shaft 1 and the driven shaft 3 rotate, the magnetic flux through the induction coil 41 is the greatest and the detection data is the most accurate.
[0060] The detection device includes a PLC. When the first magnetic body 12 and / or the second magnetic body 32 rotate, the magnetic field lines generated cut the induction coil 41. The induction coil 41 generates an induced voltage value. The PLC reads the induced voltage value and the frequency of the induced voltage value change, and calculates the rotational speed of the second magnetic body 32.
[0061] Example 2
[0062] Please refer to Figure 3 , Figure 4 As in the above embodiments, the description will not be repeated. In this embodiment, the detection device includes a Hall sensor 42, which is fixed relative to the transmission box 5 and is disposed on the outer peripheral surface of the sealing cover 2.
[0063] The Hall sensor 42 corresponds to the second magnetic body 32 along the axial direction of the driven shaft 3. The magnetic field of the second magnetic body 32 is strongest here, and the Hall sensor 42 detects the data most accurately.
[0064] There is a gap between the Hall sensor 42 and the sealing cover 2. The sealing cover 2 will heat up during rotation. Direct contact will cause the Hall sensor 42 to overheat, affecting the measurement accuracy or service life.
[0065] The magnetization direction of the first magnetic body 12 and the second magnetic body 32 is a single radial direction, and the magnetization directions of the first magnetic body 12 and the second magnetic body 32 are opposite. The N pole or S pole of the second magnetic body 32 will conduct Hall sensor 42. When the second magnetic body 32 rotates, Hall sensor 42 will sense the rotation of the second magnetic body 32. For each revolution of the second magnetic body 32, Hall sensor 42 will output a level signal equal to the number of N pole or S pole magnetic bodies. PLC reads the level signal and calculates the rotation speed of the second magnetic body 32.
[0066] Example 3
[0067] Please refer to Figure 5 As in the above embodiments, the description will not be repeated. In this embodiment, the driving shaft 1 is located outside the driven shaft 3; the first magnetic body 12 is disposed on the outer peripheral surface of the driving shaft magnet seat 11, and the second magnetic body 32 is disposed on the outer peripheral surface of the driven shaft magnet seat 31, and the two are arranged radially opposite each other; the detection device 4 includes an induction coil 41, which is laid flat on the outer peripheral surface of the sealing cover 2.
[0068] The induction coil 41 is ring-shaped and is set between the active shaft magnet seat 11 and the driven shaft magnet seat 31. The induction coil 41 corresponds to the second magnetic body 32 along the axial direction of the driven shaft 3. Here, the first magnetic body 12 and the second magnetic body 32 attract each other and the attraction force is the greatest. When the active shaft 1 and the driven shaft 3 rotate, the magnetic flux through the induction coil 41 is the greatest and the detection data is the most accurate.
[0069] Example 4
[0070] Please refer to Figure 6 As in the above embodiments, the description will not be repeated. In this embodiment, the detection device 4 includes a Hall sensor 42, which is fixed relative to the transmission box 5 and is disposed on the outer peripheral surface of the sealing cover 2.
[0071] The Hall sensor 42 corresponds to the second magnetic body 32 along the axial direction of the driven shaft 3. The magnetic field of the second magnetic body 32 is strongest here, and the Hall sensor 42 detects the data most accurately.
[0072] The Hall sensor 42 is positioned on the side away from the active shaft magnet base 11, away from the first magnetic body 12, to reduce the influence of the first magnetic body 12 on the Hall sensor 42, and to ensure that the Hall sensor 42 detects the rotation data of the second magnetic body 32, that is, the rotation data of the driven shaft 3.
[0073] There is a gap between the Hall sensor 42 and the sealing cover 2. The sealing cover 2 will heat up during rotation. Direct contact will cause the Hall sensor 42 to overheat, affecting the measurement accuracy or service life.
[0074] Example 5
[0075] Please refer to Figure 7 Similar to the embodiments described above, this embodiment will not be repeated. In this embodiment, a receiving recess 13 is provided on the end face of the drive shaft magnet seat 11, and the sealing cover 2 extends into the receiving recess 13. The second magnetic body 32 is disposed on the side wall of the driven shaft magnet seat 31, and the first magnetic body 12 is disposed on the side wall of the receiving recess 13. The first magnetic body 12 and the second magnetic body 32 are arranged radially along the drive shaft 1. The detection device includes an induction coil 41, which is laid flat on the outer peripheral surface of the sealing cover 2.
[0076] The induction coil 41 is ring-shaped and corresponds to the second magnetic body 32 along the axial direction of the driven shaft 3. Here, the first magnetic body 12 and the second magnetic body 32 attract each other and the attraction is the greatest. When the driving shaft 1 and the driven shaft 3 rotate, the magnetic flux through the induction coil 41 is the greatest and the detection data is the most accurate.
[0077] Example 6

In this embodiment, the detection device includes a Hall sensor 42, which is fixed relative to the drive shaft magnet base 11 and disposed on the outer peripheral surface of the drive shaft magnet base 11. The Hall sensor 42 moves with the drive shaft magnet base 11 and simultaneously detects the signals of the first magnetic body 12 and the second magnetic body 32. When the first magnetic body 12 and the second magnetic body 32 rotate synchronously, the first magnetic body 12 and the second magnetic body 32 are different and there is a magnetic body that conducts the Hall sensor 42. The Hall sensor 42 outputs a stable level signal. When the first magnetic body 12 and the second magnetic body 32 do not rotate synchronously, the Hall sensor 42 outputs a changing level signal and transmits it to the PLC through the wireless module. The PLC reads the level signal and calculates the rotational speed of the second magnetic body 32.
