[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4As shown, the present embodiment provides a nozzle module of a coating machine oven, comprising an array of inverted figure-eight-shaped air guide nozzles 2, both side walls of the air guide nozzles 2 being provided with through cavities near the bottom end, an adjustment component 3 being installed in the through cavity, the adjustment component 3 being composed of a baffle 303, a screw block 302, a rotating shaft 301, a thread groove 1 304 and a thread groove 2 305, one end of the rotating shaft 301 being connected to a transmission component 4, the transmission component 4 being composed of a transmission box 401, a servo motor 402, a driving wheel 403, a belt 404 and a driven wheel 405.

[0023] The baffle 303 is slidably connected to the through cavity in the air guide nozzle 2, and the two ends of the baffle 303 are symmetrically welded to the screw block 302. The baffle 303 can move in the air guide nozzle 2, and its opening can be adjusted according to actual conditions to avoid heat waste. At the same time, when the air guide nozzle 2 is not in use, the air guide nozzle 2 can be sealed by the baffle 303, which can effectively prevent dust from accumulating in the air guide nozzle 2 and affecting subsequent drying.

[0024] The thread groove 1 304 and the thread groove 2 305 are arrayed on the shaft 301 . The thread directions of the thread groove 1 304 and the thread groove 2 305 are opposite and they are arranged on both sides of the air guide nozzle 2 . When the shaft 301 rotates, the thread groove 1 304 and the thread groove 2 305 can make the movement of the screw block 302 opposite.

[0025] The screw block 302 is connected to the thread groove 1 304 and the thread groove 2 305 by threads. When the shaft 301 rotates, the screw block 302 drives the baffle 303 to move in the air guide nozzle 2 under the action of the thread groove 1 304 and the thread groove 2 305, thereby adjusting its opening.

[0026] The output shaft of the servo motor 402 is fixedly connected to the driving wheel 403 , and the belt 404 is nested on the driving wheel 403 and the driven wheel 405 . The servo motor 402 drives the driving wheel 403 to rotate, and the driving wheel 403 drives the driven wheel 405 to rotate through the belt 404 .

[0027] One end of the rotating shaft 301 is connected to the driving wheel 403 and the driven wheel 405 through threads, and the driving wheel 403 and the driven wheel 405 respectively drive the rotating shaft 301 to rotate.

[0028] An air guide pipe 1 is fixed on the upper end of the air guide nozzle 2. One end of the air guide pipe 1 is connected to an external heat source. The air guide pipe 1 guides hot air into the air guide nozzle 2 and sprays it onto the electrode sheet to dry it.

[0029] The working principle of this device is as follows: first, the air guide nozzle 2 is fixed in the drying box, the transmission box 401 is fixed on the outside of the drying box, and one end of the air guide duct 1 is connected to the external heat source. During use, the air guide duct 1 guides the hot air into the air guide nozzle 2 and sprays it out to act on the electrode sheet to dry it. During the drying process, the servo motor 402 can drive the driving wheel 403 to rotate, and the driving wheel 403 drives the driven wheel 405 to rotate through the belt 404. The driving wheel 403 and the driven wheel 405 then drive the rotating shaft 301 to rotate respectively, so that the screw block 302 drives the baffle 303 to move in the air guide nozzle 2 under the action of the thread groove 1 304 and the thread groove 2 305, and then the opening thereof can be adjusted according to the actual situation to avoid heat waste. At the same time, when the air guide nozzle 2 is not in use, the air guide nozzle 2 can be sealed by the baffle 303, which can effectively prevent dust from accumulating in the air guide nozzle 2 and affecting the subsequent drying, thereby improving the use effect of the air nozzle module.
