[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0028] The terms "comprising" and "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0029] As Figure 1-8 Shown in the air-conditioning outlet plastic spraying device, including a vertically arranged powder blocking wall 2, defining the surface of the powder blocking wall 2 facing the air-conditioning outlet structure to be sprayed as the front; the surface facing away from the air-conditioning outlet structure as the back, the powder blocking wall 2 is provided with a through groove 201 penetrating the front and back, the through groove 201 is rectangular, and the powder blocking wall 2 is provided with a toothed belt 4 in the through groove 201. The inner surface of the toothed belt 4 is provided with tooth grooves evenly arranged along the extending direction. It should be noted that the outer surface of the part of the toothed belt 4 close to the powder blocking wall 2 is flush with the front of the powder blocking wall 2. In order to ensure this flush state, the powder blocking wall 2 is also provided with a guiding strip 202 on the inner side wall of the through groove 201 for contacting the inner surface of the toothed belt 4 to form a sliding pair, so as to provide a stable supporting force for the toothed belt 4. On the other hand, the side of the toothed belt 4 contacts the inner side wall of the through groove 201 to form a sliding pair, and the inner top arm and the inner bottom arm of the through groove 201 are attached to the outer surface of the toothed belt 4 to form a sliding pair. That is to say, there is almost no gap between the toothed belt 4 and the powder blocking wall 2, and the plastic spraying powder attached to the toothed belt 4 will be scraped off by the edge of the through groove 201 of the powder blocking wall 2.

[0030] A plastic spraying arm 5 is arranged on the part of the toothed belt 4 close to the powder blocking wall 2 for spraying plastic powder on the air-conditioning outlet structure. The specific structure of the plastic spraying arm 5 includes a mounting seat 501 fixedly connected to the inner surface of the toothed belt 4. The toothed belt 4 is not provided with a tooth groove at the contact with the mounting seat 501. The end face of the mounting seat 501 is fixedly connected with a first drive 502. The first drive 502 uses a servo motor with high control precision. The output end of the first drive 502 is fixedly connected with a main shaft 503. The main shaft 503 passes through the toothed belt 4 and is fixedly connected with a turntable 504. The gap between the end face of the turntable 504 and the outer surface of the toothed belt 4 is very small, which can not only ensure the stability of the turntable 504, but also avoid large friction when the turntable 504 rotates. The end face of the turntable 504 is provided with a nozzle 508 for spraying plastic powder.

[0031] To configure the nozzle 508, a movable shaft bracket 505 is fixedly connected to the end face of the turntable 504. The nozzle 508 has a swing arm 507 movably connected to the movable shaft bracket 505. A second drive 506 is fixedly connected to the outer side of the movable shaft bracket 505 for driving the swing arm 507 to rotate relative to the movable shaft bracket 505. The shaft structure on the side of the swing arm 507 passes through the movable shaft bracket 505 and is connected to the output shaft of the second drive 506. The second drive 506 also uses a servo motor. In this way, the nozzle 508 has two degrees of rotational freedom, with better spraying flexibility, and can also spray hidden parts of the air outlet of the air conditioner. The toothed belt 4 is provided with a shaft hole 401 penetrating the inner surface and the outer surface. The main shaft 503 passes through the mounting seat 501 and cooperates with the shaft hole 401 to form a rotating pair. A pair of baffle plates 402 are fixedly connected to the outer side of the toothed belt 4. The two baffle plates 402 are respectively located above and below the shaft hole 401. That is to say, the part of the spraying arm 5 outside the toothed belt 4 is located between the two baffle plates 402, which can effectively reduce the probability of collision between the spraying arm 5 and the air outlet structure of the air conditioner, thus playing a role in protecting the spraying arm 5.

[0032] A traction mechanism 3 is arranged on the back of the powder baffle wall 2 for driving the toothed belt 4 to operate. The specific structure of the traction mechanism 3 includes a reduction motor 301 fixedly connected to the back of the powder baffle wall 2. The output end of the reduction motor 301 is fixedly connected with a gear 302, which just meshes with the toothed belt 4. In this way, the toothed belt 4 can be driven by the traction mechanism 3 to run smoothly. A fixed shaft bracket 204 is arranged on the back of the powder baffle wall 2. A bearing structure is usually arranged inside the fixed shaft bracket 204. The two ends of the gear 302 have limit rings 303. The diameter of the limit rings 303 is significantly larger than the diameter of the gear 302 for preventing the toothed belt 4 from moving on the outer surface of the gear 302. The end face of the limit ring 303 has an end shaft 304, which passes through the fixed shaft bracket 204 and is then connected to the output end of the reduction motor 301. The fixed shaft bracket 204 can well ensure the stability of rotation. The through groove 201 is also provided with a relief groove 203 at positions close to the upper and lower ends, which just fits with the limit ring 303, making the configuration of the traction mechanism 3 and the toothed belt 4 on the powder baffle wall 2 more compact.

[0033] Working principle: Under normal working conditions, there are two powder baffle walls 2. The two powder baffle walls 2 are symmetrically arranged and face each other. And a powder receiving plate 1 is fixedly connected to the bottom surfaces of the two powder baffle walls 2 together, used to receive the plastic powder that has not adhered to the air outlet structure of the air conditioner for convenient recycling.

[0034] During operation, the air outlet of the air conditioner is suspended between two powder baffle walls 2. Plastic powder is ejected from the nozzle 508. Driven by the toothed belt 4, the nozzle 508 can be adjusted in height up and down. Driven by the first drive 502 and the second drive 506, the angle of the nozzle 508 can be adjusted flexibly, so as to spray plastic powder on the air outlet of the air conditioner from different angles. Even the relatively hidden places on the air outlet of the air conditioner can be covered by the plastic powder at various different moving angles, thus making the plastic spraying process have better coverage and uniformity.

[0035] The basic principle, main features and advantages of the present application have been described above. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection required by the present application is defined by the appended claims and their equivalents.
