A blower is connected to the cabinet 101 for supplying gas to the cabinet 101 and for exhausting a portion of the gas in the cabinet 101. In some embodiments, the wall of the accommodating cavity 301 is directly opened with an air outlet 402 for air to enter the accommodating cavity and an air return 401 for air to leave the accommodating cavity. In order to enhance the baking effect and the baking uniformity, a plurality of air outlets 402 and air return openings 401 are usually required to be arranged along the moving direction of the substrate 106, and in other embodiments, in order to reduce the number of openings and the area of the openings of the box 101 and thus reduce the risk of air leakage in the box 101, the baking equipment 100 may include an air outlet 105 and an air return body 107, the air outlet 105 and the air return body 107 are arranged in the accommodating cavity 301, the air outlets 402 are arranged on the air outlet 105, and the air return openings 401 are arranged on the air return body 107.

The air blowing device can suck air in the air source 603, and the air provided by the air source 603 is used as fresh air; a part of the air in the housing chamber 301 is discharged from the air outlet 103, and the other part of the air in the housing chamber 301 is extracted by the air blowing device, and the extracted part of the air serves as return air. The blowing device can mix fresh air and return air, and heat the mixed gas formed after mixing, and the heated mixed gas is conveyed into the accommodating cavity 301 as hot air for heating the base material 106 by the blowing device. After the hot air enters the accommodating cavity 301 and bakes the substrate 106, a part of the hot air is discharged from the air outlet 103, and the other part of the hot air is pumped out by the air blowing device to be used as the return air for the next circulation.

Generally, when the toasting apparatus 100 has been turned on and operated for a period of time, although the gas drawn from the receiving chamber 301 by the blower means will have a lower temperature than the gas just fed into the receiving chamber 301, the gas drawn from the receiving chamber 301 will still have a higher temperature than the gas in the gas source 603.

When the area of the air outlet 402 shielded by the baffle 701 is small, the area of the air outlet 402 for hot air to flow out is large, and the flow rate of the hot air flowing into the accommodating cavity 301 is large; as the area of the air outlet 402 shielded by the baffle 701 gradually increases, the area of the air outlet 402 for hot air to flow out is smaller, and the flow rate of the hot air flowing into the accommodating chamber 301 is smaller.

In some embodiments, baffle 701 may be rotatably coupled to outlet body 105. Referring to fig. 10 and 11, the toasting apparatus 100 further comprises a rotating shaft 702, the baffle 701 is disposed inside the first protrusion 305, a portion of the rotating shaft 702 is also disposed inside the first protrusion 305, the rotating shaft 702 is connected to the baffle 701, one end of the rotating shaft 702 outside the first protrusion 305 can be connected to a motor (not shown), and the motor drives the rotating shaft 702 to rotate, so as to drive the baffle 701 to rotate to change the shielded area of the air outlet 402.

Referring to fig. 12, in other embodiments, the baffle 701 may be slidably connected to the air outlet body 105, the baffle 701 may penetrate into the first protrusion 305, and the baffle 701 may be connected to a cylinder (not shown), and the cylinder pushes or pulls the baffle 701, so as to change the air outlet amount of the hot air.

Generally, the speed and temperature of the hot air blown onto the surface of the substrate 106 can be increased by moving the substrate 106 closer to the outlet 402 without changing the power of the blowing mechanism and the size of the outlet 402, thereby enhancing the baking effect on the substrate 106. Therefore, to improve adjustability of the baking effect of the substrate 106, in some embodiments, the baking apparatus 100 may further include an adjustment mechanism for adjusting the distance between the air outlet 402 and the substrate 106.

Referring to fig. 13, in some embodiments, the adjustment mechanism includes a screw 306 and a nut 703. The nut 703 is rotatably installed on the box 101, one end of the screw 306 is connected to the air outlet 105, and the screw 306 penetrates through the nut 703. The screw 306 has a first thread 704 on its outer circumference, the nut 703 has a second thread 705, and the first thread 704 engages with the second thread 705. Under the gravity action of the nut 703, the screw 306 and the air outlet body 105, the nut 703 is abutted against the box body 101, and the up-down position of the nut 703 relative to the box body 101 can be regarded as unchanged; the user can rotate the nut 703 (rotate the nut 703 relative to the box 101), and simultaneously hold the air outlet body 105, so that the air outlet body 105 gradually rises or gradually falls. The screw 306 moves up and down through the thread fit between the nut 703 and the screw 306, so that the air outlet body 105 connected to the end of the screw 306 moves up and down, and the function that the air outlet body 105 is close to or far away from the base material 106 is realized. This is a relatively low cost adjustment mechanism.

In the case where the adjustment mechanism is provided in the above manner, the screw 306 may directly serve as the connecting rod 302 in fig. 2. It should be noted that, referring to fig. 2, for the screw 306 used for suspending the air outlet body 105 above, the nut 703 is located outside the accommodating cavity 301, and the bottom of the nut 703 abuts against the box body 703; for erecting the screw 306 of the air outlet body 105 located below, the nut 703 is located in the accommodating cavity 301, and the bottom of the nut 703 abuts against the bottom wall of the accommodating cavity 301.

In other embodiments, to improve the convenience of adjusting the position of the air outlet body 105, the adjusting mechanism may include a cylinder, a piston rod of the cylinder is connected to the air outlet body 105, the cylinder is installed on the box 101, and the piston rod stretches and retracts to make the air outlet body 105 close to or away from the substrate 106. Or the air cylinder can be replaced by a hydraulic oil cylinder, an electric push rod, a screw rod sliding block mechanism and the like.

If the position of the air outlet 105 is changed but the position of the return air 107 is not changed accordingly, the amount of return air may be affected. Therefore, referring to fig. 5, in order to avoid the position change of the air outlet 105 from affecting the return air volume, in some embodiments, the return air body 107 is connected to the air outlet 105 to ensure that the relative positions of the air outlet 402 and the return air inlet 401 are unchanged; the air return body 107 can be fixedly connected with the air outlet body 105 through welding, screw connection and other connection modes. The adjustment mechanism can drive the return air body 107 to move synchronously with the outlet air body 105, so that the return air inlet 401 and the outlet 402 are close to or far away from the substrate 106 synchronously.

It should be noted that, in order to match the position adjustability of the air outlet body 105, a section of the air supply pipe 203 penetrating through the box body 101 may be provided as a hose, and similarly, a section of the air return pipe 202 penetrating through the box body 101 may also be provided as a hose.

The utility model also provides a coating production line, coating production line includes the baking equipment 100 in the above-mentioned embodiment. The coating production line has the advantages that the energy consumption of the baking equipment 100 is low, and the coating production cost by utilizing the coating production line is low.

Specifically, the coating line may further include a coater, which is located upstream of the baking apparatus 100 in the coating line. In some embodiments, the coater comprises a feeder, a die, and a backing bar. The feeder is used for storing the slurry and conveying the slurry to the die head; the die is oriented toward a backing bar that supports the substrate 106 without the slurry applied thereto, and the slurry is applied to the surface of the substrate 106 after exiting the die. After the slurry is applied to the substrate 106, the substrate is transported to the baking apparatus 100 for drying.
