Orientation screening device for auricular needles

Abstract

The invention provides an orientation screening device for auricular needles. The orientation screening device for auricular needles is used for screening auricular needles. Needle grooves matched with auricular plugs are formed in the circumferential walls of one ends of the auricular needles in a concave mode. The orientation screening device for the auricular needles comprises a rack, a supporting wheel, a conveying belt and a plurality of auricular needle carriers. A protruding portion is arranged on the rack. The supporting wheel is rotationally connected with the rack. The conveying belt is arranged outside the supporting wheel in a sleeving mode. Each auricular needle carrier is provided with a connecting end and a movable end which are oppositely arranged. The connecting ends are rotationally connected with the conveying belt. The side faces, facing away from the supporting wheel, of the auricular needle carriers are provided with containing grooves used for containing the auricular needles and clamping pieces used for being connected with the needle grooves in a clamped mode. The clamping pieces are located at one ends of the containing grooves. Under the action of external force, the conveying belt can drive the auricular needle carriers to move around the supporting wheel, when the auricular needle carriers move to the protruding portion, the protruding portion can lift the movable ends of rotating plates so that the auricular needle carriers can incline, and therefore the auricular needles which are not connected with the clamping pieces in the clamped mode can slide out of the containing grooves. The auricular needles can be screened in an orientation mode, and therefore it is ensured that the needle grooves of the auricular needles are kept in the same direction.

Description

technical field [0001] The invention relates to jewelry processing equipment, in particular to an ear acupuncture directional screening device. Background technique [0002] Earrings are ornaments on the ears, which are smaller than earrings and shaped like nails. Ear studs usually include ornaments (also called ear flowers), ear pins and ear plugs. Among them, the front of the earlobe is the shape of the ear studs, that is, the ornaments, one end of the ear pins is connected to the ornaments, the ear pins pass through the ear holes, and the back of the earlobe It is an ear plug, and the ear plug is set on the ear pin to prevent the ear stud from falling out of the ear hole. In order to prevent the earplugs from moving freely along the ear needles, some earrings have needle grooves at one end of the ear needles, which can cooperate with the earplugs to locate the position of the earplugs and prevent the earplugs from being arbitrarily placed on the ear needles when wearing ...

AI Technical Summary

Problems solved by technology

For auricles with needle grooves, based on their structural limitations, existing commonly used feeding equipment, such as a vibrating plate, etc., can be used to guide the ear needles one by one, but it cannot distinguish which end of the ear acupuncture has a needle groove, and cannot The ear needles are directional screened to ensure that the ear needles of the guiding welding device keep the needle slots facing the same side. Therefore, at present, for the welding of ear studs with needle slots, manual loading is usually used. Picking up the ear needle, and then inserting the end of the ear needle away from the needle groove into the welding device for welding with the decorative parts, resulting in labor-intensive labor and a lot of labor
