[0030] With reference to Figures 1 to 6 The baking tray spraying system provided by the embodiment of the application comprises: a circulating conveying device 100, the circulating conveying device 100 is provided with a lifting appliance for hoisting a baking tray, and the circulating conveying device 100 is provided with an upper and lower feeding area 110, a pretreatment area 120, a spraying area 130 and a surface drying area 140; a pretreatment device is arranged in the pretreatment area 120, the pretreatment device comprises a dust removal mechanism 210 and a preheating mechanism 220, the dust removal mechanism 210 is used for dust removal of the baking tray, the preheating mechanism 220 is arranged downstream of the dust removal mechanism 210, and the preheating mechanism 220 is used for preheating of the baking tray; a spraying device 300 is arranged in the spraying area 130, the spraying device 300 is used for spraying of the baking tray; and a surface drying device is arranged in the surface drying area 140, the surface drying device comprises a drying mechanism 410 and a cooling mechanism 420, the drying mechanism 410 is used for drying of the baking tray after spraying, and the cooling mechanism 420 is arranged downstream of the drying mechanism 410 and is used for cooling of the baking tray after drying.

[0031] The baking tray spraying system described in the embodiment of the application can connect the pretreatment, spraying and surface drying together through the circulating conveying device 100, so that continuous production is realized, and the purposes of improving spraying efficiency, coating utilization rate, energy saving and emission reduction, reducing labor cost and the like can be achieved, and the system occupies a small space and realizes rationalized application of space.

[0032] The upper and lower feeding area 110 is arranged as an open space, and an operator can hang or take down the baking tray from the lifting appliance. By arranging the upper and lower feeding area 110 together, the transfer of the baking tray is facilitated, and the production cost is reduced.

[0033] Of course, the upper and lower feeding area 110 can also be provided with an upper and lower feeding mechanism, and the automatic feeding and discharging of the baking tray is realized through the upper and lower feeding mechanism, so that manual operation is not needed, the labor intensity is reduced, and the work efficiency is improved.

[0034] With reference to Figure 1 and Figure 2The dust removal mechanism 210 comprises a dust removal chamber 211 and a gas nozzle 212. The circulating conveying device 100 is arranged in the dust removal chamber 211. The gas nozzle 212 is arranged in the dust removal chamber 211, and the outlet of the gas nozzle 212 faces the baking tray. The gas nozzle 212 is connected with a gas supply assembly 213. Specifically, the gas supply assembly 213 sends gas into the gas nozzle 212, and blows the gas towards the baking tray through the gas nozzle 212, so as to blow away the sundries on the baking tray, thereby achieving the purpose of dust removal, and ensuring the spraying quality of the subsequent baking tray. In the embodiment, the dust removal chamber 211 is provided with a first sensor. The first sensor is used for detecting the position of the baking tray, and is connected with the circulating conveying device 100 and the gas nozzle 212 respectively. When the first sensor detects the baking tray, the first sensor transmits a signal to the circulating conveying device 100, so that the circulating conveying device 100 stops conveying. At the same time, the first sensor also transmits a signal to the gas nozzle 212, so that the gas nozzle 212 starts to spray gas for dust removal. Through the above structure, the gas sprayed by the gas nozzle 212 can fully act on the baking tray, so as to avoid the empty spraying of the gas nozzle 212, and save the cost. The gas nozzle 212 is a decentralized gas nozzle 212, so as to improve the gas spraying efficiency and enhance the dust removal effect.

[0035] With reference to Figure 1 and Figure 2 The preheating mechanism 220 comprises a preheating furnace 221, a first heating member 222 and a first air extraction assembly 223. The circulating conveying device 100 is arranged in the preheating furnace 221. The first heating member 222 is arranged at the bottom of the preheating furnace 221. The preheating furnace 221 is provided with a first air extraction opening 224 at the top. The first air extraction assembly 223 is connected with the first air extraction opening 224. Specifically, the first heating member 222 works to emit heat. At the same time, the first air extraction assembly 223 extracts air from the preheating furnace 221 through the first air extraction opening 224. At this time, the heat moves upwards under the driving of the air flow, so as to preheat the baking tray. The circulating conveying device 100 is arranged in a serpentine structure in the preheating furnace 221, so as to prolong the conveying path of the baking tray in the preheating furnace 221, and improve the preheating efficiency of the baking tray. Further, the preheating furnace 221 is provided with a temperature sensor. The temperature sensor is connected with the heating member, so as to control the temperature in the preheating furnace 221, and improve the stability and reliability.

[0036] With reference to Figure 1 , Figures 3 to 5The spraying device 300 comprises a spraying chamber 310, a plurality of robots 320 and spray guns 330. The circulating conveying device 100 is arranged in the spraying chamber 310. The robots 320 are arranged in sequence on one side of the circulating conveying device 100. The spray guns 330 are arranged on the robots 320. The outlets of the spray guns 330 are directed towards the baking trays. The spray guns 330 are connected with oil supply assemblies 340. Specifically, the circulating conveying device 100 drives the baking oven to pass through the plurality of robots 320 in sequence. Meanwhile, the oil supply assemblies 340 supply oil. The spraying of the baking trays is completed by the spray guns 330 on the robots 320.

[0037] It is conceived that the spraying chamber 310 is provided with an oil collecting groove 350 below the circulating conveying device 100. The oil collecting groove 350 is connected with the oil supply assemblies 340 through an oil pump 360. The falling oil is collected and filtered by the oil collecting groove 350. The oil is sent back to the oil supply assemblies 340 through the oil pump 360. Thus, the oil is recycled, resource is saved and cost is reduced.

[0038] It is easy to understand that the spraying chamber 310 is provided with second sensors. The second sensors are used to detect the positions of the baking trays. The second sensors are connected with the circulating conveying device 100 and the spray guns 330 respectively. When the second sensors detect the baking trays, the second sensors transmit signals to the circulating conveying device 100 to stop the rotating conveying device. Meanwhile, the second sensors transmit signals to the spray guns 330 to spray the baking trays. By using the above structure, the spray guns 330 can spray the baking trays accurately. Thus, the waste of oil is avoided.

[0039] Referring to Figure 4 In some embodiments, the spraying device 300 further comprises a water curtain assembly 370. The water curtain assembly 370 is arranged on the side of the spraying chamber 310 away from the robots 320. The water curtain assembly 370 comprises a water supply pool 371, a water curtain plate 372 and a water collecting pool 373. The water supply pool 371 is arranged on the top of the spraying chamber 310. The water curtain plate 372 is arranged below the water supply pool 371 and the top of the water curtain plate 372 is communicated with the water supply pool 371. The water collecting pool 373 is arranged on the bottom of the water curtain plate 372. The water collecting pool 373 is connected with the water supply pool 371 through a water pump 374. The water in the water supply pool 371 flows down along the water curtain plate 372. Thus, a water curtain is formed on the water curtain plate 372. At this time, the sprayed oil can be absorbed by the water curtain. Thus, the oil is prevented from being sprayed to other places. The water flows into the water collecting pool 373 along the water curtain plate 372 and is filtered. Finally, the water flows back to the water supply pool 371 through the water pump 374. Thus, the water is recycled. Further, the spraying chamber 310 is provided with a dust suction port 380. The dust suction port 380 is connected with a dust suction assembly 390. By using the above structure, the dust in the air can be sucked out from the dust suction port 380. Thus, the spraying quality of the baking trays is ensured.

[0040] Referring to Figure 1 andFigure 6 The drying mechanism 410 comprises a drying furnace 411, a second heating member 412 and a second air suction assembly 413. The circulating conveying device 100 is arranged in the drying furnace 411. The second heating member 412 is arranged at the bottom of the drying furnace 411. The second air suction opening 414 is arranged at the top of the drying furnace 411. The second air suction assembly 413 is connected with the second air suction opening 414. Specifically, the second heating member 412 works to emit heat. At the same time, the second air suction assembly 413 performs air suction on the drying furnace 411 through the second air suction opening 414. At this time, the heat moves upward under the driving of the air flow, so as to realize the drying of the baking tray.

[0041] The cooling mechanism 420 adopts natural cooling. Since the baking tray has a high temperature when it comes out of the drying furnace 411, the temperature of the baking tray is reduced through the natural cooling, so that the operator can smoothly take the baking tray from the lifting tool in the loading and unloading area 110, and the scalding is avoided.

[0042] Of course, the cooling mechanism 420 can also be cooled by blowing cold air, so as to improve the cooling efficiency and shorten the working time.
