Abstract
The utility model discloses a temperature controlling device of a drying wire hot wind machine, which is composed of a switch, a voltage regulating circuit and a heating cord, wherein the voltage regulating circuit comprises a resistance, a potentiometer, a bidirectional thyristor and a capacitor. After the resistance and the potentiometer are connected in series, the resistance and the potentiometer are connected with the control pole and the guiding angle of the bidirectional thyristor. The capacitor is connected in parallel with the bidirectional thyristor. By regulating the charging time of the potentiometer, controlling the charging time of the capacitor, and regulating the guiding angle of the bidirectional thyristor, the temperature of the heating cord is remained in the temperature range of 100 DEG C-400 DEG C all along. Thereby, the life of the heating element (the heating cord) is prolonged, and the utility model avoids burning out a product which is blown because of high temperature.
Description
Technical field
The utility model relates to a kind of baking line equipment, particularly relates to a kind of temperature control equipment that dries by the fire the line air-heater.
Background technology
In the existing footwear clothes manufacturing industry, various shoes and hats clothes can produce a lot of the end of a thread when sewing, bad if these the end of a thread are handled, and the then easy off-line of sewing place of finished product, cracking have a strong impact on the quality of product and attractive in appearance.The common practice is to adopt air-heater, the end of a thread is roasted into knot, thereby make sewing place neat and artistic.Existing baking line air-heater (as shown in Figure 1), comprise blower fan 1 ', metal bridge piece 2 ' and support 3 ', end at metal bridge piece 2 ' is provided with tiny air outlet 21 ', be provided with the heater element (not shown) near air outlet place 21 ' in the metal bridge piece 2 ', the cold wind that is blown out by blower fan 1 ' passes through metal bridge piece 2 ', heats by heater element, is carried out thermal-arrest, is blown out hot blast by tiny air outlet 21 '.The air-heater of this structure, because temperature is uncontrollable, heater element is through heating for a long time, the temperature of the hot blast that is blown out by tiny air outlet can reach 400-500 ℃, and the actual temperature that is suitable for only needs 200-300 ℃, so both wasted electric energy, and the life-span of heater element is shorter, more can Yin Wendu too high and burn out the product of being dried.
The utility model content
The purpose of this utility model is to provide a kind of temperature control equipment that can regulate temperature, baking line air-heater simple in structure automatically, and this device can make temperature remain at a certain temperature range.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of temperature control equipment that dries by the fire the line air-heater, and it mainly is made up of switch, voltage regulator circuit and heating wire; Described switch is connected the input of voltage regulator circuit, and heating wire connects the output of voltage regulator circuit; Described voltage regulator circuit comprises resistance, potentiometer, bidirectional thyristor, capacitor, and described resistance, potentiometer series connection back connect the control utmost point of bidirectional thyristor, the angle of flow of control bidirectional thyristor, and capacitor is in parallel with bidirectional thyristor.
The utility model also comprises working indicating, and described working indicating is made up of working station indicator and temperature display watch, and this working station indicator, temperature display watch are in parallel with heating wire.
After adopting such scheme, the utility model mainly is made up of the voltage regulator circuit that comprises bidirectional thyristor, pass through regulator potentiometer, the charging interval of control capacitor, regulate the angle of flow of bidirectional thyristor, can make the temperature of heater strip remain at 200-300 ℃ of temperature range, thereby prolong the life-span of heater element (heating wire) greatly, avoid Yin Wendu too high and burn out the product of being dried.In addition, the element that the utility model adopted is less, and structure is comparatively simple, and is cheap.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of commonly using baking line air-heater;
Fig. 2 is a circuit diagram of the present utility model;
Fig. 3 is a structural representation of using baking line air-heater of the present utility model.
Embodiment
As shown in Figure 2, the utility model is a kind of temperature control equipment that dries by the fire the line air-heater, and it mainly is made up of switch 1, voltage regulator circuit 2, heating wire 3, working indicating 4, power supply indicator 5, blower fan 6, fuse 7.
Described switch 1 is connected the input of voltage regulator circuit 2, and heating wire 3 connects the output of voltage regulator circuit 2.
Described voltage regulator circuit 2 comprises resistance R, potentiometer RP, bidirectional thyristor VS, capacitor C, and described resistance R, potentiometer RP series connection back connect the control utmost point of bidirectional thyristor VS, and described capacitor C is in parallel with bidirectional thyristor VS.In this circuit, by the size of regulator potentiometer RP resistance, the charging interval of control capacitor C, the angle of flow of control bidirectional thyristor VS, thereby the height of control output voltage.，
Described working indicating 4 is made up of working station indicator H and temperature display watch P, and this working station indicator H, temperature display watch P are in parallel with heating wire 3.
Operation principle of the present utility model:
Increase the resistance of potentiometer RP, capacitor C charging has slowly promptly postponed capacitance voltage and has arrived the time that makes bidirectional thyristor VS conducting, that is increased pilot angle, and the angle of flow of bidirectional thyristor VS is reduced, output voltage reduces, otherwise output voltage raises, thereby reaches the purpose of pressure regulation.
Fig. 3 uses baking line air-heater of the present utility model, and it comprises blower fan 6, support 8, bridge piece 9; Described blower fan 6 is located in the support 8, bridge piece 9 stretches out outside the support 8 and with the efferent duct of blower fan 6 and is connected, the part that bridge piece 9 is connected with the efferent duct of blower fan 6 is a PVC bellows 91, and PVC bellows 91 passes support 8 shells and is connected with metal winding pipe 92.The end of metal winding pipe 92 is provided with air outlet 93, is provided with heating wire 3 (as Fig. 2) near air outlet 93 places in the metal winding pipe 92.
