[0049] This application provides an embodiment of a drying module. Figure 1 and Figure 2 .

[0050] The drying module in this embodiment includes an oven, which is provided with an upper air chamber 4 and a lower air chamber 6. An upper air nozzle 5 is provided at the bottom of the upper air chamber 4, and a lower air nozzle 7 is provided at the top of the lower air chamber 6. The oven is provided with a lifting and opening and closing mechanism 1 for driving the upper air chamber 4 and the lower air chamber 6 to move closer to or away from each other. Upper air outlets 8 and lower air outlets 9 are provided on the side walls of the oven. Exhaust hoods for adjusting exhaust uniformity are movably provided at the upper and lower air outlets 8 and 9. External adjustment rods 10 are correspondingly provided on the outside of the oven for driving the exhaust hood to move forward and backward. In this embodiment, the oven can be provided with an operating door 2.

[0051] It should be noted that: this drying module uses the lifting and opening and closing mechanism 1 to move the upper air chamber 4 and the lower air chamber 6 away from each other, which can expand the operating space inside the oven and facilitate maintenance. At the same time, the external adjustment rod 10 can drive the exhaust hood to move back and forth, thereby facilitating the adjustment of the exhaust of the upper exhaust port 8 and the lower exhaust port 9, so that the exhaust on both sides is uniform, so as to avoid product defects such as product shaking, deviation, uneven heating, etc. caused by poor exhaust backflow.

[0052] The above is an embodiment of a drying module provided in the embodiment of the present application. The following is an embodiment of a drying module provided in the embodiment of the present application. For details, please refer to Figures 1 to 4 .

[0053] The drying module in this embodiment includes: an oven, an upper air chamber 4 and a lower air chamber 6 are provided in the oven, an upper air nozzle 5 is provided at the bottom of the upper air chamber 4, and a lower air nozzle 7 is provided at the top of the lower air chamber 6, and the oven is provided with a lifting and opening and closing mechanism 1 for driving the upper air chamber 4 and the lower air chamber 6 to move closer to or away from each other, an upper exhaust port 8 and a lower exhaust port 9 are provided on the side wall of the oven, and exhaust hoods for adjusting the uniformity of exhaust are movably provided at the upper exhaust port 8 and the lower exhaust port 9, and an external adjusting rod 10 for driving the exhaust hood to move back and forth is correspondingly provided outside the oven. In this embodiment, an operating door 2 can be provided on the oven, and an observation window can be provided on the operating door 2.

[0054] Specifically, there are two external adjustment rods 10, and the two external adjustment rods 10 respectively control the opening and closing amount of the upper exhaust port 8 and the lower exhaust port 9, so as to facilitate the adjustment of the exhaust of the upper exhaust port 8 and the lower exhaust port 9, thereby making the exhaust on both sides uniform.

[0055] The external adjustment rod 10 is a screw rod, one end of which extends into the oven and is connected to the exhaust hood through a pull rod 11; the screw rod is threadedly connected to the oven, the screw rod is rotationally connected to the pull rod 11, and the pull rod 11 is fixedly connected to the exhaust hood.

[0056] It should be noted that: by designing the exhaust hood to be adjustable forward and backward, and setting the external adjustment rod 10 that drives the exhaust hood to move forward and backward on the outside of the oven, it is possible to observe and operate through the observation window on the operating door 2 during normal startup, avoiding the problem of inconvenience in operation due to the high temperature environment inside the oven.

[0057] A limiting plate is arranged on the movable path of the exhaust hood; and an exhaust distance is provided between the side of the limiting plate away from the exhaust hood and the side wall of the oven.

[0058] The lifting and opening and closing mechanism 1 includes a rotating rod body 3 arranged at the top of the oven for rotation in the vertical direction and a driving device for driving the rotating rod body 3 to rotate. A first pulley 19, a second pulley 20, a third pulley 21 and a fourth pulley 22 are provided on the top of the oven. The first pulley 19, the second pulley 20, the third pulley 21 and the fourth pulley 22 are symmetrically arranged on the left and right sides of the rotating rod body 3 respectively. One end of the rotating rod body 3 is hinged with a first pull rope 23 and a second pull rope 24, and the other end is hinged with a third pull rope 25 and a fourth pull rope 26; the end of the first pull rope 23 away from the rotating rod body 3 is fixedly connected to the lower air chamber 6 through the first pulley 19, the end of the second pull rope 24 away from the rotating rod body 3 is fixedly connected to the upper air chamber 4 through the fourth pulley 22, the end of the third pull rope 25 away from the rotating rod body 3 is fixedly connected to the upper air chamber 4 through the third pulley 21, and the end of the fourth pull rope 26 away from the rotating rod body 3 is fixedly connected to the lower air chamber 6 through the second pulley 20. Specifically, the driving device may be a motor or a cylinder; the first pull rope 23, the second pull rope 24, the third pull rope 25 and the fourth pull rope 26 may all be steel ropes.

[0059] The upper air chamber 4 and the lower air chamber 6 are both provided with air chamber guide plates 12 for evenly distributing the hot air. Specifically, the air chamber guide plates 12 include at least two guide plates; at least two guide plates are arranged in parallel along the wind speed direction.

[0060] It can be understood that by setting the air chamber guide plate 12, the incoming air can be evenly distributed to each air nozzle under the action of the air chamber guide plate 12, ensuring that the air volume allocated by each air nozzle is consistent, and then the hot air is blown to the product through the air nozzle for uniform drying, which can avoid the problem of uneven heating of the product caused by uneven hot air output.

[0061] A plurality of nozzle docking positions 13 are symmetrically provided on the upper air chamber 4 and the lower air chamber 6 . The upper air nozzle 5 is mounted on the nozzle docking position 13 on the upper air chamber 4 , and the lower air nozzle 7 is mounted on the nozzle docking position 13 on the lower air chamber 6 .

[0062] It also includes: an air intake mechanism for supplying air to the upper air chamber 4 and the lower air chamber 6, the air intake mechanism includes an air intake fan 16, an air intake pipe 14 and a heating pack 15, the air intake fan 16 is connected to the air intake pipe 14, the heating pack 15 is arranged in the air intake pipe 14, and the air intake pipe 14 is respectively connected to the upper air chamber 4 and the lower air chamber 6.

[0063] The air intake device further comprises an exhaust mechanism connected to the upper air outlet 8 and the lower air outlet 9. The exhaust mechanism comprises an exhaust fan 17 and an exhaust pipe 18, wherein the exhaust fan 17 is connected to the exhaust pipe 18, and the exhaust pipe 18 is connected to the air inlet end of the air intake fan 16.

[0064] During specific implementation, the air intake fan 16 is running, the air enters the air intake pipe 14, and is heated by the heating pack 15 before entering the upper air chamber 4 and the lower air chamber 6 respectively. At this time, the hot air is evenly diverted to each nozzle docking position 13 under the action of the air chamber guide plate 12, ensuring that the hot air volume of each nozzle docking position 13 is consistent, and then the hot air is blown to the product through the upper air nozzle 5 and the lower air nozzle 7 to dry it evenly. At the same time, in order to prevent a large amount of hot air from generating positive pressure, the exhaust fan 17 can be started to discharge the hot air from the upper exhaust port 8 and the lower exhaust port 9 in time. In order to avoid uncertain factors such as the fluctuation of the drying effect of the product during exhaust, the exhaust hood can be driven back and forth by twisting the external adjustment rod 10, and the adjustment status of the upper exhaust port 8 and the lower exhaust port 9 can be observed from the observation window on the operating door 2, so that the hot air can flow back evenly on both sides of the upper air chamber 4 and the lower air chamber 6, and the exhaust is smoother.

[0065] When maintenance is required, the upper air chamber 4 can be controlled to move upwards by the lifting and opening and closing mechanism 1, while the lower air chamber 6 can be moved downwards, so that there is a larger maintenance space in the middle for convenient operation. When the operation is completed, it can be started again to return to its original position.
