Description

Glue heat-preserving container monitoring temperature warning device

Technical field

The utility model relates to the monitoring temperature warning device, is specially capsule glue heat-preserving container monitoring temperature warning device, belongs to light industry food, medicine-making machine technical field.

Background technology

Existing medicine glue is in the course of processing, need to stir described glue average rate in heat-preserving container, heat simultaneously and remain on design temperature, its type of heating carries out Long-distance Control by electric heater, temperature and resistance sensor, solid-state relay and temperature controller.in actual use procedure, electric heater damage or heating pipe often occurring blows, the situations such as solid-state relay major loop switch contact burns out, but this moment, temperature controller showed heating, heat-insulation system is also also in normal operation, in fact not normal operation of glue heat-preserving container, cause the heat-preserving container glue temperature to descend too low, but operating personal can not in time be found, if this moment, operating personal was not in time found and handling failure, can cause the interior glue of heat-preserving container bubble to occur, the serious quality accidents such as fiber crops bubble, what impact was produced normally carries out, bring the very large hidden danger of quality to product.

Summary of the invention

The utility model is for the deficiencies in the prior art, designs a kind of easy to use, safe, practical, quick glue heat-preserving container monitoring temperature warning device intuitively.

The technical solution of the utility model is: a kind of glue heat-preserving container monitoring temperature warning device comprises:

Be used for the electric heating tube of glue in the heat tracing bucket and be used for controlling electric heating tube getting solid-state relay electric or outage;

For detection of the temperature and resistance sensor of glue temperature in heat-preserving container with control the controller that the solid-state relay major loop is switched on or switched off;

It is characterized in that: also comprise install one for detection of the electric heating tube main circuit current, and current signal that this current sensing means is detected and controller provide that signal compares or the broken-circuit controller that compares with the solid-state relay control signal and by the warning indicator lamp of described broken-circuit controller control.

Its beneficial effect is: in work, to observe warning indicator lamp long when bright when operating personal, there is fault in the electric heating system that shows the glue heat-preserving container, and in time notify the machine repair personnel to keep in repair, avoided this glue heat-preserving container temperature to descend and caused the quality problems such as bubble, fiber crops bubble, guarantee normally carrying out of production, guaranteed product quality. ?

The specific embodiment

This glue heat-preserving container monitoring temperature warning device comprises electric heating tube, solid-state relay temperature and resistance sensor, solid-state relay, controller, broken-circuit controller and warning indicator lamp.

Temperature and resistance sensor measurement glue temperature, controller is controlled the solid-state relay major loop according to measured glue temperature and is switched on or switched off;

Solid-state relay is to control electric heating tube to get electric or breaker device, when in the glue heat-preserving container, glue temperature does not reach design temperature, solid-state relay is connected, electric heating tube gets electric, the heating glue, when glue heats up, when the temperature and resistance sensor detects glue and reaches design temperature, controller is controlled solid-state relay and is disconnected, electric heating tube dead electricity, i.e. stopped heating.

Control process: temperature and resistance sensor measurement glue temperature, controller is controlled the solid-state relay major loop according to measured glue temperature and is switched on or switched off.

Faulty condition: controller has sent solid-state relay major loop connection signal, the deserved electricity of electric heating tube also heats glue, but broken-circuit controller does not detect electric heating tube and obtains current signal at this moment, prove that solid-state relay damages, or electric heating tube opens circuit.The broken-circuit controller working process is: an electric heating tube main circuit current detecting device is arranged in broken-circuit controller, and the signal that current sensing means detects and controller provide that signal compares or compare with the solid-state relay control signal.

Normal condition: when controller sends the electric heating tube power on signal, and broken-circuit controller is when major loop being detected current signal being arranged, and system is normal, otherwise reports to the police.

In case break down, electric heating system can not be worked, broken-circuit controller detect that this electric heating tube is answered On current and in fact no current by the time, the trigger alarm indicator lamp is long bright automatically immediately.It is long when bright that operating personal is observed this warning indicator lamp, there is fault in the electric heating system that shows this glue heat-preserving container, just can in time notify the machine repair personnel to keep in repair, avoided the interior glue temperature of this glue heat-preserving container to descend too much, thereby cause quality problems such as occurring bubble, fiber crops bubble in glue, guarantee normally carrying out of production, guaranteed product quality.
