Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical equipment, and in particular relates to a high-precision hemispherical temperature measuring device. Background Art

[0002] In the process of making popcorn with a popcorn machine, temperature sensors are often needed to control the temperature of the oil drum and syrup drum. The K-type sensor we are familiar with has the following defects during use. When the oil drum is fitted with the sensor, it is easy to damage the sensor due to its large mass. Only when the sensor is tightly fitted on the oil drum can the temperature in the oil drum or syrup drum be accurately measured, so that the heating can be controlled according to the pre-set temperature. Since the sensor is often damaged during use, the maintenance cost and work efficiency of the equipment are greatly increased. Especially in popcorn machine equipment, a sensor device is needed that can accurately measure the temperature of the oil drum or syrup drum and is not easily damaged during use.

The protective shell is cylindrical, and the right side of the protective shell is an opening. A circular baffle is welded on the left side of the protective shell. The circular baffle is used to prevent the K-type sensor from sliding out of the left side of the protective shell. A data cable is connected to the left side of the K-type sensor, and the data cable can pass through the circular hole of the circular baffle. The K-type sensor can be inserted through the K-type sensor entry hole and keep the right side contact spring of the K-type sensor protruding out of the K-type sensor entry hole. The upper and lower parts of the annular fixed plate I are welded with moving plates, and the moving plate can drive the protective device to move left and right in the track.

The upper and lower parts of the track frame are respectively provided with threaded holes I and threaded holes II for fixing the entire device on the equipment.

[0005] The working principle of the present invention is as follows: the K-type sensor monitors the temperature of the syrup barrel or the oil barrel under the protection of the protective device. When the oil barrel or the syrup barrel hits the protective device, under the action of force, the entire protective device can move backward in the track to reduce the force acting on the oil barrel or the syrup barrel. On the other hand, it is ensured that the shrapnel of the K-type sensor is tightly combined with the oil barrel or the sugar barrel to be measured. The hemispherical protective shell ensures that the syrup barrel or the oil barrel will not scratch the K-type sensor when it contacts the K-type sensor at any position of 360 degrees. The data line of the K-type sensor is connected to the temperature controller, and the temperature controller heats according to the set temperature. The proximity switch is connected to the controller to determine that the oil barrel or the syrup barrel to be measured has contacted with the K-type sensor. After it is determined that the contact has occurred, a reminder is given in the form of an indicator light, thereby facilitating people to operate and preventing the oil barrel or the syrup barrel from being disconnected from the K-type sensor for a long time and affecting the normal operation of the equipment.

[0006] The present invention has the following advantages: novel and unique design, reasonable structure, reducing the damage and replacement of the K-type sensor, being able to reduce the maintenance cost of the equipment, ensuring the long-term stable operation of the equipment, and being able to better determine whether the K-type sensor is in normal and close contact with the oil drum or syrup drum.
