Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a nut counting device for assisting an artificial quality inspection table as shown in Figures 1-3 the figure, which includes a blanking hopper 1. The blanking hopper 1 is set as a funnel structure. An annular proximity switch 2 is fixedly arranged at the bottom end of the blanking hopper 1. An elbow 3 is fixedly arranged at the bottom end of the annular proximity switch 2. A discharge pipe 4 is fixedly arranged at the bottom end of the elbow 3;

[0022] Specifically, a partition 5 is fixedly arranged inside the blanking hopper 1. A circular groove 6 is penetratingly opened in the middle of the partition 5. A fixed seat 7 is fixedly arranged inside the circular groove 6, and the fixed seat 7 is set as a conical structure. A material bucket 8 is fixedly arranged at the bottom end of the fixed seat 7. A through groove 9 is penetratingly opened at the top end of the outer side wall of the material bucket 8. A guide plate 10 is arranged inside the material bucket 8. The guide plate 10 is set as a spiral structure and is attached to the inner side wall of the material bucket 8. The width of the guide plate 10 corresponds to the nut, and only one nut can be conveyed at the same position;

[0023] More specifically, a drive motor 11 is fixedly arranged at the top end inside the fixed seat 7. A drive rod 12 is fixedly arranged on the output shaft of the drive motor 11, and the bottom end of the drive rod 12 is connected to the bottom end of the guide plate 10. The material bucket 8 is set as a bucket-shaped structure with a large top and a small bottom. A conical communication groove 13 is arranged at the bottom end inside the blanking hopper 1, and the communication groove 13 can play a role in guiding the nuts;

[0024] And, a counter 14 is electrically connected to the outside of the annular proximity switch 2. The counter 14 can receive and record the electrical signals generated by the annular proximity switch 2. An opening 15 is opened at the top end of the outer side wall of the discharge pipe 4.

[0025] Working principle of the utility model:

[0026] When the device is in use, nuts can be placed into the blanking hopper 1 and guided through the annular proximity switch 2 by the blanking hopper 1. During the process of the nuts passing through the annular proximity switch 2, an alternating magnetic field is generated by the oscillator inside the annular proximity switch 2, generating an eddy current. The oscillator changes and generates an electrical signal, which is transmitted to the counter 14 through the circuit to achieve the counting of nuts. After passing through the annular proximity switch 2, the nuts enter the next process under the guidance of the elbow pipe 3 and the discharge pipe 4;

[0027] During the process of the nuts entering the blanking hopper 1, the nuts are first guided by the fixed seat 7 to disperse above the partition plate 5, and then enter the material bucket 8 through the gap between the circular groove 6 and the fixed seat 7. At this time, the driving motor 11 drives the guide plate 10 to rotate. During the rotation of the guide plate 10, the nuts can be driven to move upward. Since the width of the guide plate 10 corresponds to the nuts, only one nut can be conveyed at the same position of the guide plate 10. After following the guide plate 10 to move to the top of the material bucket 8, the nuts enter the blanking hopper 1 through the through groove 9, slide downward along the inner wall of the blanking hopper 1, and then pass through the communication groove 13 into the annular proximity switch 2.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
