Description

TECHNICAL FIELD

[0001] The utility model relates to a pearl conveying device. BACKGROUND

[0002] The pearl conveying device with the pearl feeding clamp structure is provided with a driving shaft for driving the pearl feeding clamp to open and close at different times, and a cam on the driving shaft is used to drive the pearl feeding clamp to open and close at different times.

[0003] When the length of the driving shaft is too long, the cam on the driving shaft and the corresponding pearl feeding clamp are matched, the driving shaft is used in the existing device, the cam is used to drive the pearl feeding clamp to act, the driving shaft exerts force on the pearl feeding clamp through the cam, and the driving shaft is easily elastically bent and deformed under the action of the reaction force. In particular, the middle part of the driving shaft is easily elastically bent and deformed, the cam on the bent driving shaft cannot accurately control the angle and time length of the driving pearl feeding clamp to open, and therefore the smooth falling of the pearls from top to bottom and from one clamp to another cannot be ensured.

[0004] In particular, when large-diameter pearls are fed and conveyed, the cam needs to be accurately matched with the pearl feeding clamp to drive the pearl feeding clamp to open, at this time, a slight deformation of the driving shaft will cause the cam to drive the pearl feeding clamp to open insufficiently, which will affect the smooth falling of the pearls from top to bottom and from one clamp to another.
