[0036] See also Figure 1-8 The present invention provides a technical solution: a coating production line conveying device that can automatically identify, classify and convey, according to Figure 1-4 As shown, the output end of the driving motor 1 can drive the first driving wheel 102 to rotate through the driving rod 101, and the first driving wheel 102 is connected to the first driven wheel 104 through the first transmission belt 103.

[0037] Specifically, the first driven wheel 104 is installed on the outside of the first rotating rod 105, and the second driving wheel 106 is arranged on the outside of the first rotating rod 105. The second driving wheel 106 can drive several groups of second driven wheels 108 arranged on both sides to rotate through the second transmission belt 107. The second driving wheel 106 and the second driven wheel 108 can drive several groups of conveying rollers 3 arranged on the inner side of the mounting frame 2 to rotate. Air outlets are opened on both sides of the bottom of the mounting frame 2, and dust filters 201 are arranged inside the air outlets. The dust filters 201 can prevent external impurities and dust from entering the interior of the mounting frame 2 through the dust filters 201. One end of the driving rod 101 penetrates into the interior of the mounting frame 2 and is connected to the first bevel gear 4, and the first bevel gear 4 is meshed with the second bevel gear 401. The second bevel gear 401 is installed on the outside of the second rotating rod 402, and several groups of third bevel gears 403 are arranged on the outside of the second rotating rod 402. The third bevel gear 403 is connected to several groups of suction mechanisms 5 arranged inside the mounting frame 2. A filter cloth 6 is arranged on the top of the suction mechanism 5. The filter cloth 6 can filter the exhaust gas entering the mounting frame 2. The filter cloth 6 is detachably connected to the inside of the mounting frame 2 to facilitate the later disassembly and maintenance of the filter cloth 6. An activated carbon block 7 is installed at the bottom of the suction mechanism 5. The top of the activated carbon block 7 is provided with conical air inlets 701 distributed at equal distances, and the conical air inlets 701 are connected to the curved air holes 702 that penetrate the inside of the activated carbon block 7. The curved air holes 702 are used to make the exhaust gas and the activated carbon impact, thereby improving the adequacy of the contact and increasing the adsorption and deodorization effect.

[0038] Specifically, the air suction mechanism 5 includes symmetrically arranged fan blades 501, and the fan blades 501 are installed on the outside of the fan blade rod 502, a worm 503 is arranged on the outside of the lower end of the fan blade rod 502, and the worm 503 is meshed with the worm 504, the worm 504 is connected to the fourth bevel gear 505, and the fourth bevel gear 505 is meshed with the third bevel gear 403.

[0039] When in use, the driving motor 1 is turned on and the first driving wheel 102 is driven to rotate through the driving rod 101 under the action of the driving motor 1. The first driving wheel 102 drives the first driven wheel 104 and the first rotating rod 105 to rotate through the first transmission belt 103. The first rotating rod 105 can drive the second driving wheel 106 to rotate synchronously, so that the second driving wheel 106 drives several groups of second driven wheels 108 and the conveying roller 3 to rotate to convey the object. At the same time, under the action of the rotation of the driving rod 101, the second bevel gear 401 and the second bevel gear 404 are driven through the first bevel gear 401. The rotating rod 402 rotates, and the second rotating rod 402 can drive several groups of third bevel gears 403 to rotate synchronously. Since the third bevel gear 403 is meshed with the fourth bevel gear 505, it can drive the fourth bevel gear 505 and the worm 504 to rotate. Under the action of the rotation of the worm 504, the worm gear 503 drives the fan blade rod 502 and the fan blade 501 to rotate and absorb air, so that the external exhaust gas enters the inside of the mounting frame 2 for purification, and the purified gas is discharged through the air outlet. At the same time, the rotation of the fan blade 501 can speed up the gas flow, thereby speeding up the air-drying speed of the object after spraying.

[0041] Specifically, the identification mechanism 802 includes a fixed frame 8021, and a first electric telescopic rod 8022 is arranged on the top of the fixed frame 8021, and the first electric telescopic rod 8022 can drive the sliding plate 8023 arranged inside the fixed frame 8021 to move, and four sets of sleeves 8024 are symmetrically arranged at the bottom of the sliding plate 8023, and the inside of the sleeve 8024 is slidably connected with the moving rod 8025, and the inside of the sleeve 8024 is installed with a second electric telescopic rod 8026 that drives the moving rod 8025 to move, and the bottom of the sliding plate 8023 and one side of the moving rod 8025 are installed with a collection camera 8027, and the collection camera 8027 can adopt a model XY-R982 0-K2, and the acquisition camera 8027 can send the acquired data to an external remote terminal. When the spray-dried object moves to the bottom of the fixed frame 8021 under the action of the conveying roller 3, the second electric telescopic rod 8026 is turned on at this time to drive the moving rod 8025 and the acquisition camera 8027 set on one side of the moving rod 8025 to move downward. After the movement is completed, the first electric telescopic rod 8022 can be turned on to further adjust the height of the multiple groups of acquisition cameras 8027. After the position adjustment of the acquisition camera 8027 is completed, the object is collected and photographed and sent to the remote terminal for identification and classification, so that it moves to the top of the corresponding transmission mechanism 903.

[0042] Specifically, the adjustable guide wheel mechanism 902 includes several groups of discs 9021, and four groups of guide wheels 9022 are arranged on the top of the disc 9021, a driving rod 9023 is installed at the bottom of the disc 9021, and a gear 9024 is arranged on the outside of the driving rod 9023, the gear 9024 is meshed with a rack plate 9025, and stabilizing plates 9026 are installed at both ends of the rack plate 9025, one group of stabilizing plates 9026 is connected to a positioning plate 9028 arranged inside the positioning groove through a connecting rod 9027, and a third electric telescopic rod 9029 is installed on the outside of the conveying platform 901 to drive the positioning plate 9028 to move.

[0043] To further explain, the rack plate 9025 moves inside the movable transverse groove opened in the conveyor platform 901, and the stabilizing plate 9026 is slidably connected to the inside of the movable transverse groove. By providing the stabilizing plate 9026, the stability of the rack plate 9025 during movement can be improved.

[0044] To further explain, the positioning groove is symmetrically provided with a limit slide bar, and the limit slide bar is slidably connected to the positioning plate 9028. By providing the limit slide bar, the moving direction of the positioning plate 9028 can be further limited.

[0045] When in use, the third electric telescopic rod 9029 is turned on. Under the action of the third electric telescopic rod 9029, the positioning plate 9028 drives the stabilizing plate 9026 and the rack plate 9025 to move through the connecting rod 9027. Under the action of the movement of the rack plate 9025, the gear 9024 rotates, thereby driving the disc 9021 to rotate through the driving rod 9023, so that the conveying direction of the guide wheel 9022 changes, and the guide wheel 9022 will convey the object to the top of the conveying mechanism 903 on the side of the deflection direction, thereby realizing classified conveying.
