DETAILED DESCRIPTION

[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] like Figure 1 This is a schematic diagram of the structure of the utility model, a curing furnace for high sweat-resistant galvanized steel plates, comprising a furnace body 1, a transmission mechanism 2, a ventilation mechanism 3 and a plurality of curing mechanisms 4.

[0019] like Figure 2 As shown, the furnace body 1 has a curing chamber 11 inside, and an inlet and an outlet are provided on the furnace body 1 for inputting or outputting steel plates, and a door curtain can be installed at the outlet to reduce heat loss, and the paint surface will not be damaged by the door curtain after being cured.

[0020] like Figure 2 As shown, the transmission mechanism 2 is used to transport the steel plate. The transmission mechanism 2 is fixedly connected to the furnace body 1. The output end of the transmission mechanism 2 passes through the curing chamber 11 of the furnace body 1 and extends outside the furnace body 1. The transmission mechanism 2 can be a roller transmission device, or a chain / belt transmission device, etc.

[0021] like Figure 1 , Figure 2 As shown, the ventilation mechanism 3 is fixedly connected to the top surface of the furnace body 1, and the ventilation mechanism 3 is used to remove water vapor and exhaust gas in the curing chamber 11 of the furnace body 1. The ventilation mechanism 3 includes a ventilation pipe 31 and a fan 32. The input end of the ventilation pipe 31 is connected to the curing chamber 11. The fan 32 is installed in the ventilation pipe 31. The fan 32 is used to provide power for the flow of air. Multiple ventilation mechanisms 3 can be installed to prevent water vapor or chemicals generated by the coating or paint from affecting subsequent processing during the curing process.

[0022] like Figure 2 , Figure 3As shown, the curing mechanism 4 is an electric heating tube or a gas heater. The curing mechanism 4 is arranged in the curing chamber 11, and the curing mechanism 4 is spaced apart along the width direction of the transmission mechanism 2. By arranging the curing mechanism 4 along the width direction of the transmission mechanism, the curing uniformity of the steel plate in the width direction can be increased. The curing mechanism 4 and the furnace body 1 are connected by an adjusting mechanism 5. The adjusting mechanism 5 is used to adjust the position of the curing mechanism 4. The design of the adjustable curing mechanism 4 can, on the one hand, increase the curing efficiency and reduce the heat source loss. On the other hand, the curing mechanism 4 can be aligned with the steel plate to ensure the curing effect.

[0023] like Figure 2 , Figure 3 As shown, the adjustment mechanism 5 includes a lifting component 51 for adjusting the distance between the curing mechanism 4 and the transmission mechanism 2, and the lifting component 51 includes a driving member 511, a screw rod 512, a mounting frame 513 and a movable frame 514. The movable frame 514 is fixedly connected to the curing mechanism 4, and the driving member 511 is a motor. The driving member 511 and the mounting frame 513 are fixedly connected. The output end of the driving member 511 and the head end of the screw rod 512 are transmission-connected. The driving member 511 is used to provide power for the rotation of the screw rod 512. The screw rod 512 and the movable frame 514 are threadedly connected to control the distance between the curing mechanism 4 and the steel plate, thereby reducing heat dissipation loss, thereby improving curing efficiency, and being able to use the production of steel plates of different thicknesses. It not only controls the curing speed by controlling the power of the curing mechanism 4, but also can control it in the direction of reducing heat loss, thereby reducing energy consumption and reducing production costs.

[0024] The present application may also arrange driving members 511 and screw rods 512 on both sides of the movable frame 514 to further improve the stability of the movement of the movable frame 514; when the driving members 511 and screw rods 512 are arranged on only one side, the other end of the movable frame 514 is slidably connected to the mounting frame 513 to increase stability.

[0025] like Figure 2 , Figure 3 As shown, a movable cavity 5131 for the movable frame 514 to move is opened on the mounting frame 513 , and the end of the movable frame 514 is arranged in the movable cavity 5131 to increase the connection strength and provide stability for the movement of the movable frame 514 .

[0026] like Figure 2 , Figure 3 As shown, the tail end of the screw rod 512 is rotatably connected to the mounting bracket 513 , which increases the stability of the screw rod 512 during rotation and prevents it from shaking and affecting the curing mechanism 4 .

[0027] like Figure 2 , Figure 3As shown, the adjustment mechanism 5 includes a translation assembly 52, and the translation assembly 52 includes a slide rail 521 and a slider 522 matching the slide rail 521. The slide rail 521 is fixedly connected to the furnace body 1, and the extension direction of the slide rail 521 is the same as the transmission direction of the transmission mechanism 2. The slide rail 521 and the slider 522 are slidably connected, and the slider 522 is fixedly connected to the mounting frame 513 to achieve a correction effect to prevent the center of the steel plate from deviating from the fixed center, which affects the curing effect. The translation assembly 52 can also be a moving mechanism such as a screw moving mechanism or a hydraulic cylinder, and this application does not make any specific limitations on this.

[0028] During curing, the transmission mechanism 2 transports the steel plate into the curing chamber 11, the sensor detects the position of the steel plate, and the translation assembly 52 starts to move the curing mechanism 4 in the transmission direction, thereby adjusting the curing center of the curing mechanism 4 and the center of the steel plate. After positioning the curing center and the center of the steel plate, the drive member 511 starts to rotate the screw rod 512 so that the curing mechanism 4 descends close to the steel plate, thereby increasing the utilization rate of the curing heat.

[0029] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
