Abstract
The utility model discloses a temperature monitoring device for an oven, which comprises a thermocouple, a sensor, a PLC (programmable logic controller) and an HMI (human-machine interface). The thermocouple is installed inside a cavity body of the oven and is connected with the PLC through the sensor; and the PLC is also connected with the HMI. The temperature monitoring device can facilitate the reflection of temperature changes inside the oven in real time, prevent product scrapping caused by slow reflection of the temperature changes of an original system, adjust the temperature curve of the oven more quickly and shorten the equipment debugging time.
Description
Technical field
The utility model relates to the oven temperature supervising device.
Background technology
Baking box is the product component that has glue to be heated dry cooling then, its control principle cooperates shown in Figure 1, is made up of the stainless steel cavity 10 of two open ends, and the both sides of cavity 10 are equipped with thermocouple 20, heater strip 30 is installed in the below of cavity 10, is used for cavity 10 is heated.
The defective that present baking box exists is:
One, thermocouple 20 is installed on the cavity 10 outside sidewalls, can't promptly and accurately reflect the variation of cavity 10 internal temperatures, if cavity 10 internal gas flows change, the variations in temperature that causes can't in time feed back on the thermocouple 20, will cause the quality risk of product;
Two, between the limber up period of equipment,,, in debug process, need to spend long time so can't in time see the effect of equipment debugging because thermocouple 20 in cavity 10 outsides, can't in time feed back cavity 10 temperature inside.
In view of this, the inventor relies in professional knowledge, and Roasting oven structure is studied, and develops a kind of device for monitoring temperature that is applicable to baking box, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of oven temperature supervising device, so that reflecting the baking box temperature inside in real time changes, prevent to shorten the equipment debugging time because the product rejection that the reflection of original system variations in temperature slowly causes can be adjusted the oven temperature curve more apace.
To achieve these goals, solution of the present utility model is:
The oven temperature supervising device, comprise that thermocouple, sensor, PLC Programmable Logic Controller (abbreviation of Programmable logic Controller) and HMI man-machine interface (also named " man-machine interface ", the abbreviation of Human Machine Interface), at the inner thermocouple of installing of oven cavity, thermocouple is connected with the PLC Programmable Logic Controller by sensor, and the PLC Programmable Logic Controller is connected with the HMI man-machine interface again.
Described thermocouple is installed in four districts of oven cavity inside, and 3 thermocouples are respectively installed in each district.
Described HMI man-machine interface also is connected to beacon by output module.
After adopting said structure, the utility model is because at the inner thermocouple of installing of oven cavity, feed back among the PLC by the temperature of sensor these thermocouples, and in PLC, programme, the instantaneous value with temperature is presented on the HMI simultaneously, realizes that thus reflection baking box temperature inside changes in real time, prevent because the product rejection that the reflection of original system variations in temperature slowly causes, and, can adjust the oven temperature curve more apace, shorten the equipment debugging time.
The utility model also can be provided with the bound of warning on HMI, to beacon, inform operator's alarm condition by the output module output alarm signal.
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be elaborated.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the use schematic diagram that the utility model applies to baking box.
Label declaration
Thermocouple 1 sensor 2
PLC Programmable Logic Controller 3 HMI man-machine interfaces 4
Output module 5 beacons 6
The specific embodiment
As shown in Figures 2 and 3, a kind of oven temperature supervising device that the utility model discloses mainly comprises thermocouple 1, sensor 2, PLC Programmable Logic Controller 3 and HMI man-machine interface 4.
The utility model also is installed in thermocouple 1 oven cavity 10 inside except installing the thermocouple 20 on cavity 10 outside sidewalls, specifically be to require four relatively stricter districts respectively to increase by 3 thermocouples 1 in the control of oven cavity 10 internal temperatures.These thermocouples 1 are connected with PLC Programmable Logic Controller 3 by sensor 2, and PLC Programmable Logic Controller 3 is connected with HMI man-machine interface 4 again.By these thermocouples that increases newly 1, can know the variations in temperature in the baking box in real time, in case changing, cavity 10 internal temperatures overrun, in time report to the police and stop to produce, reduce the quality risk of product; And in debug process, change with reference to oven cavity 10 temperature inside in real time, reduce the time of equipment debugging.
And present embodiment also is provided with the bound of warning on HMI man-machine interface 4, to beacon 6, informs operator's alarm condition by output module 5 output alarm signals.
The utility model can reflect the variations in temperature of cuing open in the baking box, mistake proofing error correction timely more apace.
The above is preferred embodiment of the present utility model only, is not the qualification to the utility model practical range, and all variation and modifications of being done according to design main points of the present utility model all fall into its protection domain.
