[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A coating machine sampling device comprises a coating machine body 1, a machine cover 2 and a sampling device body 3. The machine cover 2 is fixedly mounted on one end of the coating machine body 1, and the sampling device body 3 is arranged on a side of the machine cover 2 away from the coating machine body 1.

[0025] Among them, the sampling device body 3 includes a vacuum suction box 32 fixedly installed on the machine cover 2 through an installation and fixing component 31, and a sampling tube 34 is movably installed on the side of the vacuum suction box 32 close to the machine cover 2 through a mechanical gear transmission component 33. The top surface of the vacuum suction box 32 is provided with a vacuum generating component 35, and the vacuum generating component 35 includes a filter cartridge 351 installed through the top surface of the vacuum suction box 32, and a filter core 352 is embedded in the interior of the filter cartridge 351. A cartridge cover 353 is spirally installed on the top of the filter cartridge 351, and a connecting vacuum tube 354 is fixedly installed at the center of the top surface of the cartridge cover 353. A vacuum generator body 355 is spirally installed on the top of the connecting vacuum tube 354. A vacuum suction end 3551 is provided at the bottom end of the vacuum generator body 355, and compressed air inlet ports are provided at both ends of the vacuum generator body 355. The end 3552 and the diffuser exhaust end 3553 are connected to the compressed air inlet end 3552 and the external compressed air source, and then a vacuum state is formed under the action of the compressed high-speed jet through the set vacuum generator body 355. At this time, under the action of the pressure difference, the material inside the coating machine body 1 is sucked into the interior of the vacuum suction box 32 through the sampling tube 34. At the same time, the air containing dust enters the interior of the filter cylinder 351 and is filtered under the action of the filter core 352, and then discharged by the vacuum generator body 355. By filtering the air containing a large amount of dust in the coating machine that is sucked in, pollution or even blockage of the interior of the vacuum generator body 355 is avoided, and it is beneficial to protect the external air environment. At the same time, the filter cylinder 351 and the cylinder cover 353 are provided to facilitate the replacement of the filter core 352.

[0026] In addition, in this embodiment, please refer to Figure 3The installation and fixing component 31 includes a first mounting bracket 311 and a second mounting bracket 312 fixedly mounted on both sides of the bottom of the vacuum suction box 32. The first mounting bracket 311 and the second mounting bracket 312 are fixedly connected by a connecting rod 313. The connecting rod 313 passes through the interior of the machine cover 2 at one end close to the coating machine body 1. The connecting rod 313 and the machine cover 2 are fixedly connected by a fixing nut 314. The design of the installation and fixing component 31 can fix the sampling device body 3 and the machine cover 2, which is beneficial to the stability and reliability of the sampling device body 3 during operation.

[0027] In addition, in this embodiment, please refer to Figure 3 An air hole 321 is provided on the top surface of the vacuum suction box 32 near the vacuum generating assembly 35. A hopper 322 is fixedly installed at the bottom center of the vacuum suction box 32. A discharge pipe 323 with a valve is fixedly installed at the bottom end of the hopper 322. The material sucked into the vacuum suction box 32 will fall into the interior of the hopper 322 due to gravity, and finally can be discharged by the discharge pipe 323 with a valve. At the same time, the air containing dust enters the interior of the filter cartridge 351 through the air hole 321.

[0028] In addition, in this embodiment, please refer to Figure 4 The mechanical gear transmission assembly 33 includes a driven gear 331 sleeved on the outer surface of the sampling tube 34, the top of the driven gear 331 is meshed with a driving gear 332, and a gear drive motor 333 is provided on the side of the driving gear 332 away from the machine cover 2. The gear drive motor 333 is fixedly mounted on the top surface of the vacuum suction box 32 through the motor mounting base 334. When the gear drive motor 333 works, the driving gear 332 starts to rotate under its action, and drives the driven gear pair 331 to rotate. At this time, the sampling tube 34 continues to rotate until the end of the sampling tube 34 away from the vacuum suction box 32 contacts the material on the bottom surface of the coating machine body 1. The design of the mechanical gear transmission assembly 33 helps to automatically mechanically adjust the sampling position of the sampling tube 34.

[0029] In addition, in this embodiment, please refer to Figure 4 The sampling tube 34 is arranged in an arc shape. The end of the sampling tube 34 away from the vacuum suction box 32 passes through the interior of the machine cover 2 and extends to the interior of the coating machine body 1. The end of the sampling tube 34 close to the vacuum suction box 32 is fixedly connected to the limiting ring 341, and the limiting ring 341 can limit the sampling tube 34 to prevent it from being separated from the vacuum suction box 32 during the adjustment of the sampling position.

[0030] In this embodiment, the implementation scenario is specifically as follows: when sampling the internal material of the coating machine body 1, the gear drive motor 333 works first, under its action, the driving gear 332 starts to rotate, and drives the driven gear pair 331 to rotate, at this time the sampling tube 34 rotates continuously until the sampling tube 34 is away from the vacuum suction box 32 and contacts the material on the bottom surface of the coating machine body 1, and then the compressed air inlet end 3552 is connected to the external compressed air source, and then a vacuum state is formed under the action of the compressed high-speed jet through the vacuum generator body 355. At this time, under the action of the pressure difference, the coating machine body The material inside the body 1 is sucked into the interior of the vacuum suction box 32 through the sampling tube 34, and the material sucked into the vacuum suction box 32 will fall into the interior of the hopper 322 due to the action of gravity, and can finally be discharged by the discharge pipe 323 with a valve. At the same time, the air containing dust enters the interior of the filter cylinder 351 through the air hole 321, and is filtered under the action of the filter element 352, and then discharged by the vacuum generator body 355. By filtering the air containing a large amount of dust in the coating machine, pollution or even blockage of the interior of the vacuum generator body 355 can be avoided, and it is also beneficial to protect the external air environment.
