[0016] By adopting the technical scheme, although the pushing assembly improves the utilization rate of the bottle caps in the feeding box, the worker needs to press the pushing plate on both sides of the feeding box when pouring the bottle caps into the feeding box, which requires another worker to assist in pouring the bottle caps, which is very inconvenient. The fixing assembly solves this technical problem. By arranging the fixing assembly, the worker can first pull the fixing screw so that the fixing screw approaches the fixing screw hole, and then twist the fixing screw to screw the U-shaped plate through the fixing screw hole. In this way, the pushing plate is fixed in the storage groove by the fixing screw, and the worker can pour the bottle caps into the feeding box, so that the worker can complete the feeding without the assistance of others. When the pushing plate needs to work normally, the worker only needs to twist the fixing screw to separate the U-shaped plate.

[0017] Further, the feeding box is externally provided with two fixing assemblies for fixing the pushing plate on both sides.

[0018] By adopting the technical scheme, the worker can observe the number of bottle caps in the feeding box, so as to add bottle caps.

[0019] In summary, the present application has at least one of the following beneficial technical effects:

[0020] By arranging the feeding device, the worker can pour the bottle caps into the feeding box when feeding. Part of the bottle caps poured into the feeding box falls into the feeding groove. Then, the driving motor is started to drive the feeding cylinder to rotate until the feeding groove is aligned with the discharge port. In this way, the bottle caps in the feeding groove fall onto the conveying device through the discharge port. Then, the feeding cylinder continues to rotate to reload a batch of bottle caps on the feeding groove. The above process is repeated again, so that the feeding device replaces the worker to complete the feeding of a small number of times. The worker only needs to pour a large number of bottle caps into the feeding box at one time, which achieves the purpose of making the worker feed more easily and conveniently.
