Description

Technical Field

[0001] The utility model relates to the field of thermocouples, in particular to a wear-resistant thermocouple. Background Art

[0002] A vulcanizing machine is a machine that vulcanizes various rubber products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. Among them, the thermocouple is an important component for temperature detection.

[0003] At present, the temperature of rubber products is measured when they are stirred during the use of the vulcanizer to prevent the rubber from being overheated during extrusion. However, in actual production, the rubber often wears out the measuring part due to extrusion, which greatly reduces the temperature measurement effect. In addition, the service life is short, and the detection device needs to be replaced frequently, resulting in high costs. Utility Model Content

[0008] Preferably, thermal conductive silicone grease is filled between the inner cavity of the wear-resistant tube and the thermocouple.

[0009] Preferably, the wear-resistant tube can be made of high-chromium cast iron, wear-resistant high-temperature alloy, or stainless steel.

[0010] The advantages and positive effects of the utility model are:

[0011] 1. The utility model increases the service life of the wear-resistant tube by setting the wear-resistant tube to wear-resistant material, while ensuring the temperature measurement of the wear-resistant tube and rubber extrusion contact, thereby reducing production costs and consumables consumption.

[0012] 2. The utility model drives the wear-resistant tube downward by rotating the hollow tube, so that the unworn part replaces the worn position and continues to contact the object to be measured for temperature measurement, thereby increasing the service life while always maintaining high-precision temperature measurement.

[0013] 3. The utility model rotates the screw, which drives the threaded rack to engage with the thread, thereby clamping the hollow tube and continuing to rotate, thereby avoiding the vibration generated by the equipment itself during stirring, which causes the hollow tube to automatically rotate and drive the wear-resistant tube to fall.

[0021] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0022] See also Figure 1-3 The utility model provides an embodiment: a wear-resistant thermocouple, comprising a hollow tube 11, one end of the hollow tube 11 is fixedly connected to a wear-resistant tube 12, the wear-resistant tube 12 is made of wear-resistant material, the other end of the hollow tube 11 is connected to a B-type junction box 10, a thermocouple 13 is provided at the bottom of the inner cavity of the wear-resistant tube 12, the output end of the thermocouple 13 is connected to a wire 14, a thread 19 is provided on the outer wall of the hollow tube 11, a flange 15 is provided on the outside of the hollow tube 11, and the flange 15 can be The flange 15 is rotated on the hollow tube 11 by a thread 19, and a groove 17 is provided on the inner wall of the flange 15. A threaded rack 18 is provided in the groove 17. The threaded rack 18 can engage with the thread 19, so that the flange 15 is stuck on the outer wall of the hollow tube 11. A screw 16 is provided on the inner wall of the groove 17 through a thread. The screw 16 is rotatably connected to the threaded rack 18, and the screw 16 can drive the threaded rack 18 to slide in the inner cavity of the groove 17.

[0023] In addition, in one embodiment, a terminal post 20 is provided on the inner wall of the B-type junction box 10 , and the terminal post 20 is connected to the other end of the wire 14 .

[0024] In addition, in one embodiment, thermal conductive silicone grease is filled between the inner cavity of the wear-resistant tube 12 and the thermocouple 13 .

[0025] In addition, in one embodiment, the wear-resistant tube 12 can be made of high-chromium cast iron, wear-resistant high-temperature alloy, or stainless steel.

[0026] During specific implementation, the device is screwed through the flange 15, and the flange 15 is fixed to the specified position of the vulcanizer to fix the whole. At this time, the wear-resistant tube 12 is exactly located between the two rollers, and the rubber product is continuously squeezed and stirred between the two rollers. The rubber will generate a lot of heat when it is stirred and squeezed. The wear-resistant tube 12 is located between the two rollers and will always be in contact with the rubber. The temperature is detected by the thermocouple 13, and then a signal is transmitted to the external device through the wire 14 to determine whether it is within a safe temperature range. In order to make its measurement accurate, the wear-resistant tube 12 is always in contact with the rubber. The two rollers will squeeze the wear-resistant tube 12 while stirring the rubber, which will cause wear of the wear-resistant tube 12. We use wear-resistant materials. While ensuring accurate measurement, it increases service life. When the wear-resistant tube 12 is worn for a long time, the diameter of the part in contact with the rubber will become smaller. At this time, the hollow tube 11 is rotated, and the hollow tube 11 drives the wear-resistant tube 12 to descend, so that the unworn part is in close contact with the rubber, so as to more accurately measure the temperature value and increase the service life. When the wear is serious, the hollow tube 11 can be lowered, so that the unworn part replaces the worn position and continues to contact the rubber to increase the service life. After adjusting the position of the hollow tube 11, the screw 16 is rotated, and the screw 16 drives the threaded rack 18 to engage with the thread 19 to stop the rotation of the hollow tube 11, prevent the equipment from constantly vibrating during stirring, and make the hollow tube 11 automatically rotate.

[0027] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
