[0002] In the current spraying process, as a key device for transporting the objects to be sprayed to the spraying area, the feeding device's transmission efficiency and stability directly affect the overall efficiency of the spraying production line. Existing feeding devices mostly use robotic arms, conveyor belts, etc. Although they can achieve a certain degree of automation, there are still many problems under the requirements of high speed and high precision.

[0003] For example, a feeding device for spraying disclosed in the Chinese Patent Publication No. (CN214526369U) includes a conveying line. Below the conveying line, there is a hanger for hooking the sheet metal. On one side of the conveying line, there is an installation frame extending horizontally.

A lifting rope is provided on the electric hoist. Below the lifting rope, there is a pulling member for driving the sheet metal to rise. This application can facilitate workers to feed the sheet metal.

[0004] However, in the prior art exemplified by the above-mentioned disclosed patent, there is still a problem of poor clamping and conveying effect for the objects to be sprayed. When facing diversified and complex-shaped objects to be sprayed, existing feeding devices lack flexibility and precise positioning ability, and are prone to mechanical fatigue during long-term high-intensity operation, affecting service life and maintenance cost. Summary of the Utility Model
