Description

Technical Field

[0001] The utility model relates to the technical field of gem processing, in particular to an automatic gem nesting machine. Background Art

[0002] Jewelry and jade, referred to as gemstones for short, are minerals, rocks and organic materials that are colorful, crystal clear, hard and durable, rare and can be cut and carved into jewelry and handicrafts. They are mainly used as fashion jewelry, handicrafts and decorations.

[0003] The bead-forming machine is a mechanical equipment used to process jewelry, jade and other materials. It is used to grind irregularly shaped raw stones into spherical or specific-shaped beads. At the same time, it can grind raw stones in batches, greatly improving production efficiency.

[0004] The existing automatic bead-forming machine is usually composed of a feeding mechanism and a grinding mechanism. The feeding mechanism mainly includes a feeding channel, a cylinder and a baffle plate. The feeding channel is used to transport irregularly shaped raw stones to the grinding mechanism for grinding and shaping. After the feeding is completed, the cylinder drives the baffle plate to move in the direction close to the feeding channel, so that the baffle plate closes the feeding channel. However, the baffle plate is prone to hard contact with the raw stone staying on the feeding channel, and the raw stone is easily damaged by the impact. At the same time, when the cylinder encounters an obstruction during the driving process, the internal parts of the cylinder such as the piston and the piston rod are impacted, which are prone to mechanical damage such as wear and deformation. In addition, the cylinder will continue to drive the baffle plate to overcome the resistance to complete the predetermined stroke and move to the feeding channel. In the long run, the service life of the cylinder is seriously affected. Utility Model Content
