[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model can realize the function of fixing the first shell to the outside of the curing furnace body through the installation component, and can blow the external wind into the inner cavity of the curing furnace through the air outlet mechanism. At the same time, the gas around the curing furnace can be transported through the gas transmission mechanism, thereby improving the practicality of the device.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 As shown, a duct structure for a curing furnace comprises a first shell 1, and the inner sides of the upper end and the lower end of the outer surface of the first shell 1 are symmetrically fixedly connected with mounting components 2, which can realize the function of installing and fixing the first shell 1 on the outside of the curing furnace body, and the inner side of the inner cavity of the first shell 1 is fixedly connected with an air outlet mechanism 3, which can realize the function of blowing the external wind into the inner cavity of the curing furnace, and the outer annular array of the air outlet mechanism 3 is fixedly connected with a plurality of gas transmission mechanisms 4, which can realize the function of conveying the gas around the curing furnace, and the middle part of the outer surface of the first shell 1 is provided with a shaping belt 5, which can realize the function of limiting and fixing a plurality of gas collecting mechanisms 6, and the outer annular array of the first shell 1 is provided with a plurality of gas collecting mechanisms 6, which can realize the function of guiding the gas around the curing furnace into the inside of the gas transmission mechanism 4, and a plurality of gas collecting mechanisms 6 are provided in an annular array on the outer surface of the shaping belt 5.

[0022] In order to achieve the purpose of installing and fixing the first shell 1 on the outside of the curing furnace body, refer to Figure 2 The mounting assembly 2 includes a fixing ring 21, and a plurality of fastening screws 22 are threadedly connected in an annular array on the outer surface of the fixing ring 21, which can realize the function of installing and fixing the new air duct structure on the outside of the curing furnace to be used.

[0023] In order to achieve the purpose of blowing the external air into the cavity of the curing furnace, refer to Figure 2 The air outlet mechanism 3 includes a positioning ring 31, and a plurality of tapered tubes 32 are fixedly connected to the inner surface of the positioning ring 31 in an annular array, which can disperse the introduced gas into the inner cavity of the curing furnace.

[0024] In order to achieve the purpose of transporting the gas around the curing oven, refer to Figure 3 The gas delivery mechanism 4 includes an air inlet pipe 41, and an air delivery pipe 42 is fixedly connected to one end of the outer surface of the air inlet pipe 41 close to the middle of the inner cavity of the first shell 1, and the outer surface of the air delivery pipe 42 close to the middle of the inner cavity of the first shell 1 is fixedly connected to the outer surface of the corresponding tapered tube 32.

[0025] When the gas around the curing furnace enters the inner cavity of the air inlet pipe 41, when it enters the inner cavity of the air delivery pipe 42 with a smaller diameter from the air inlet pipe 41 with a larger diameter, the air flow rate will be accelerated due to the reduction in the cross-sectional area of ​​the channel. Therefore, the flow rate of the gas in the inner cavity of the air delivery pipe 42 will be accelerated to a certain extent, and finally evenly sprayed out to the middle of the inner cavity of the first shell 1 through the tapered tube 32.

[0026] In order to achieve the purpose of limiting and fixing the plurality of gas collecting mechanisms 6, refer to Figure 4 , the shaping belt 5 is made of thermoplastic material.

[0027] Through this design, several air collecting pipes 61 can be fixed conveniently. The high elasticity of the shaping belt 5 can clamp several air collecting pipes 61 and make them stably fixed on the outer surface of the first shell 1, avoiding the phenomenon of falling off.

[0028] In order to achieve the purpose of draining the gas around the curing furnace into the gas delivery mechanism 4, refer to Figure 4 The gas collecting mechanism 6 includes a gas collecting pipe 61. A plurality of side through grooves 62 communicating with the outside are provided in a circular array on one side of the outer surface of the gas collecting pipe 61 away from the middle of the inner cavity of the first shell 1, which can facilitate the gas around the curing furnace to enter the inner cavity of the gas collecting pipe 61. A vent 63 communicating with the outside is provided on one end of the outer surface of the gas collecting pipe 61 away from the middle of the inner cavity of the first shell 1, and an end of the outer surface of the gas collecting pipe 61 close to the middle of the inner cavity of the first shell 1 is sleeved on the outer surface of the corresponding air inlet pipe 41.

[0029] The working principle of the present invention is as follows: first, the new air duct structure is installed and fixed on the outside of the curing furnace body through two sets of fixing rings 21. At this time, the cold air or hot air around the curing furnace will first enter the inner cavity of the air collecting pipe 61 along the inner cavities of several side grooves 62 and several air holes 63, and then enter the inner cavity of the air delivery pipe 42 along the corresponding inner cavity of the air inlet pipe 41, until finally the surrounding cold air or hot air is evenly discharged into the inner cavity of the curing furnace through the corresponding tapered tube 32.
