[0015] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] A long net automatic drying device for rubber strips, as Figure 1 shown, includes a drying box 1 and a controller. A plurality of conveyor net belts 3 are installed in the drying box 1 in a vertically arranged and staggered manner. A feed inlet 2 is communicated and arranged at the top of the drying box 1. An air inlet pipe 6 communicated with a blower is installed at the bottom of the drying box 1. A plurality of blowing pipes 7 facing the conveyor net belt 3 are arranged on the air inlet pipe 6. A plurality of heating plates 4 for heating the air conveyed into the drying box 1 through the air inlet pipe 6 are further installed inside the drying box 1. The controlled end of the heating plate 4 is connected to the output end of the controller, capable of uniformly drying the rubber strips. An inclined discharge chute 5 is installed at the bottom of one end of the lowermost conveyor net belt 3 of the drying box 1.

[0017] The heating plates 4 are respectively arranged above the conveyor net belt 3 and at the center of the annular opening of the conveyor net belt 3, capable of simultaneously drying the upper and lower surfaces of the rubber strips on the conveyor net belt 3, ensuring the uniformity of heat reception during drying.

[0018] The heating plate 4 is composed of a heat conducting plate and a plurality of electric heating rods, and the electric heating rods are evenly installed at intervals on the heat conducting plate.

[0019] An electromagnetic valve is arranged on the air inlet pipe 6 outside the drying box 1, and the controlled end of the electromagnetic valve is connected to the output end of the controller.

[0020] A temperature sensor is provided on the heating plate 4, and the output end of the temperature sensor is connected to the input end of the controller to timely regulate the temperature of the heating plate.

[0021] A dehumidifier 8 is also provided on the top of the drying oven 1, and the controlled end of the dehumidifier 8 is connected to the output end of the controller.

[0022] The dehumidifier 8 is communicated with the exhaust pipe 9, and can extract and process the heated humid air for reuse, avoiding the accumulation of humid air in the drying oven and affecting the drying effect.

[0023] During use, first, start the heating plate 4, and then convey air into the drying oven 1 through the air inlet pipe 6 and preheat the air.

[0024] Then, send the rubber strip into the drying oven 1 from the feed inlet 2. During the process of transporting the rubber strip by the conveyor belt 3, the heating plate 4 will cooperate with the air blown by the blowing pipe 7 to dry the rubber strip on the conveyor belt 3.

[0025] During the drying process, the temperature of the heating plate is timely monitored by the temperature sensor to prevent the drying effect from being affected by too high or too low temperature.

[0026] The rubber strip on the upper conveyor belt 3 will fall onto the lower conveyor belt 3 for re-drying to enhance the drying effect until the rubber strip is discharged from the discharge chute 5.

[0027] During drying, the dehumidifier 8 can also be started to extract the dried humid air, which is discharged through the exhaust pipe 9 and recycled.
