Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: a kind of method that prevents that the glue spreader steel band is on fire, at first the roller that an energy rolls on steel band is set on the steel band of glue spreader, be provided with the metal sensing chip on roller, approach switch is installed arranging on the support of roller, when steel band normally moves, roller normally rolls on steel band, and approach switch detects roller and rotates, the heating generator normal operation; When steel band runs into fault and stops travelling forward, approach switch can't detect roller and rotates, then send signal to high frequency fireproof alarming circuit and control and cut off heating generator control power supply, heating generator quits work simultaneously, and warning device begins to report to the police, by such method, prevent that steel band glue on steel band after stopping from catching fire because of excess Temperature.
A kind of device that prevents that the glue spreader steel band is on fire, comprise the frame 1 and the heating generator 6 that are arranged on glue spreader, be provided with the roller 2 that rolls on can the steel band at glue spreader on frame 1, be provided with metal sensing chip 3 on roller 2, be provided with the approach switch 4 that can sense metal sensing chip 3 on roller 2 on frame 1, approach switch 4 is connected with alarm lamp 5 with heating generator 6 by high frequency fireproof alarming circuit.
Be provided with 2～4 metal sensing chips 3 on roller 2.
High frequency fireproof alarming circuit is comprised of approach switch, auxiliary reclay and the time relay.
High frequency fireproof alarming circuit connects as described below: be connected with approach switch SP and auxiliary reclay KA1 controlling between voltage two ends; The normally opened contact of auxiliary reclay KA1 is connected with the control coil of time relay KT1 to receive and is controlled voltage two ends; The normally closed contact of auxiliary reclay KA1 is connected with the control coil of time relay KT2 to receive and is controlled voltage two ends; Be connected in series to auxiliary reclay KA2 control coil after the normally opened contact parallel connection of the normally opened contact of time relay KT1 and time relay KT2 and control voltage two ends, be connected in series to alarm lamp 5 after the normally opened contact parallel connection of the normally opened contact of time relay KT1 and time relay KT2 and control voltage two ends; The normally closed contact of auxiliary reclay KA2 and heating generator 6 are connected in series to controls voltage two ends.
Control voltage is AC220v.
High frequency fireproof alarming circuit is a kind of control circuit of routine, as shown in Figure 3, comprises auxiliary reclay KA1 and time relay KT1.Auxiliary reclay is a kind of existing relay protection and automatic control system of being used for, to increase quantity and the capacity of contact, it is used for transmitting M signal at control circuit, and the contact of auxiliary reclay can only pass through little electric current, so it can only be used for control circuit; Time relay KT1 is that a kind of existing electromagnetic principle or mechanical principle utilized realizes the recloser that time-delay is controlled, often adopt in early days the air damping type time relay in alternating circuit, it is to utilize air to obtain deferred action by the principle of orifice restriction, it is comprised of electromagnetic system, time-delay mechanism and contact three parts, after every relay sensing element obtained actuating signal, its executive component (contact) will postpone the relay that certain hour just moves and be called the time relay;
During work, at first a roller 2 that can roll along with steel band 6 operations is set on the steel band 6 of glue spreader, roller 2 can be taken turns for woollen goods, be provided with metal sensing chip 3 on roller 2, be provided with approach switch 4 on the frame 1 of roller 2, approach switch 4 is used for detecting the rotation of roller 2, as shown in Figure 3, when steel band 6 normally moves forward, roller 2 rotates, heating generator 7 normal operations;
Approach switch SP senses metal sensing chip SP and connects auxiliary reclay KA1 coil when roller 2 stops operating, and auxiliary reclay KA1 usually leaves the closing of contact, and time relay KT1 coil gets electric; Get electric when arriving setting-up time [time relay is set in second action] the KT1 time closing closed auxiliary reclay KA2 coil of often making war, the control power supply heating generator 7 that the normally closed point of KA2 disconnects heating generator 7 quits work, heating generator 7 quits work, the temperature of steel band just can not continue to rise yet, glue on steel band just can not catch fire yet, and while alarm lamp FM begins the alert notice operator and checks reason.
When approach switch SP does not sense metal sensing chip 3 when roller 2 stops operating, auxiliary reclay KA1 coil losing electricity, auxiliary reclay KA1 is normally closed closed, time relay KT2 coil gets electric, when arriving setting-up time [time relay is set in second action] the KT2 time closing closure of often making war, auxiliary reclay KA2 coil gets electric; The normally closed point of KA2 disconnects the control power supply of high-frequency heating apparatus, and heating generator 7 quits work, and while alarm lamp FM begins the alert notice operator and checks reason.
Before in July, 2011, I do not install this warning device by company's workshop streamline, the mould that causes due to steel band, debugging problem etc. blocks steel band, heating generator causes glue frequent generation on fire, such situation had 5,6 times in one day, all must use a large amount of flame snuffers to put out a fire, personal security is on the hazard at every turn; And also and then there is disaster hidden-trouble simultaneously in the equipment around heating generator, company property is on the hazard at any time, after using this device in July, 2011, my workshop streamline mistake on fire never again, this warning device significantly promotes the security of production equipment, improve staff's personal safety, greatly reduced use and the disaster hidden-trouble of flame snuffer, thereby saved a large amount of valuable funds for company.
