[0003] The Chinese patent with application publication number CN104213345A discloses a pearl arranging mechanism, which is arranged on a rack, and includes: a material cup, which is fixedly connected to the rack, and has a through hole in the center of the bottom and a round hole, and the center of the round hole is just matched with the center of a guide pearl rod; a paddle frame, which is arranged on a transmission shaft penetrating through the whole rack and passing through the through hole of the bottom of the material cup, and is provided with a stirring paddle on the paddle frame. The pearl arranging mechanism is only suitable for selecting and arranging round pearls, and cannot arrange flat bottom middle hole drill pearls in a specific orientation with the top surface upward. Therefore, an urgent need exists for a mechanism capable of selecting and arranging flat bottom middle hole drill pearls in a specific orientation, so as to ensure that the flat bottom middle hole drill pearls maintain the correct orientation during the operation of the embroidery machine and improve the production efficiency of pearl embroidery. SUMMARY

[0004] The present application is to solve the problem that the pearl arranging mechanism in the prior art cannot arrange flat bottom middle hole drill pearls in a specific orientation with the top surface upward, and provides a pearl arranging device with simple structure, stable operation, high production efficiency and the ability to arrange flat bottom middle hole drill pearls in a specific orientation with the top surface upward.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a bead sorting and arranging device for flat-bottomed medium-hole drill beads of the present invention comprises a material cup and a bead sorting turntable, the bead sorting turntable is arranged in the material cup and can rotate relative to the material cup, a bead sorting groove is provided on the bead sorting turntable, an isolation baffle is provided on the inner wall of the material cup, the isolation baffle is located above the bead sorting turntable, the isolation baffle, the bead sorting turntable and the inner wall of the material cup are surrounded to form an independent bead arranging chamber, the lower end of the side of the isolation baffle facing the rotation direction of the bead sorting turntable is provided with a bead selection port that can only allow flat-bottomed medium-hole drill beads with the top surface facing upward in the bead sorting groove to pass through, and a bead dropping hole is provided at the bottom of the material cup located below the bead arranging chamber. In the present invention, the bead sorting turntable rotates relative to the material cup, and the bead sorting turntable and the bottom of the material cup can be in contact or in clearance. The rotation of the bead sorting turntable can adopt various conventional technical means, such as transmitting the rotation through a transmission shaft passing through the material cup; the bead sorting groove is used to accommodate flat-bottomed middle-hole drill beads, and the flat-bottomed middle-hole drill beads in the bead sorting groove are continuously transported to the bead selection port as the bead sorting turntable rotates; the longitudinal cross-section shape of the flat-bottomed middle-hole drill beads is asymmetrical up and down, and by utilizing this feature of the flat-bottomed middle-hole drill beads, it is sufficient to set the shape of the bead selection port to match the longitudinal cross-section shape of the flat-bottomed middle-hole drill beads in the desired direction (top surface facing up). When the bead sorting turntable rotates, the flat-bottomed middle-hole drill beads are The bottom middle-hole drill beads rotate with the bead sorting turntable in the bead sorting trough. When they reach the bead selection port, the flat-bottom middle-hole drill beads with the top surface facing upwards, whose longitudinal cross-sectional shape matches the bead selection port, can smoothly pass through the bead selection port into the bead discharge chamber and be discharged from the bead dropping hole. Those flat-bottom middle-hole drill beads with incorrect directions will not be able to pass through the bead selection port and will be blocked outside the bead discharge chamber because their longitudinal cross-sectional shape does not match the shape of the bead selection port; the isolation baffle also plays an isolation role, preventing the flat-bottom middle-hole drill beads in the material cup from entering the bead discharge chamber and affecting the bead discharge; the present invention can effectively screen the flat-bottom middle-hole drill beads according to the required direction through the cooperation of the bead sorting turntable and the bead selection port, thereby greatly improving production efficiency.

The driving part can move relative to the driven part, the driving part drives the driven part and the opening and closing cover to pivot to realize the automatic opening and closing of the feeding pipe. The opening between the opening and closing cover and the feeding pipe in a closed state means that the flat bottom center hole drill beads in the feeding pipe cannot fall into the material cup from the opening between the opening and closing cover and the feeding pipe, that is, there is no opening (completely closed) between the opening and closing cover and the feeding pipe, or the opening between the opening and closing cover and the feeding pipe is so small that the flat bottom center hole drill beads in the feeding pipe cannot pass through; the opening between the opening and closing cover and the feeding pipe in an open state means that the opening between the opening and closing cover and the feeding pipe can make the flat bottom center hole drill beads in the feeding pipe fall into the material cup for feeding, the number of falling beads (feeding) can be controlled by controlling the size of the opening between the opening and closing cover and the feeding pipe; by setting the feeding pipe, the feeding hopper, the opening and closing cover, the driving part and the driven part, the frequency and number of flat bottom center hole drill beads entering the material cup can be conveniently controlled, and the degree of automation is high, without manual operation, further improving the production efficiency.
