[0023] Example

[0024] See also Figure 1-3 As shown:

[0025] The utility model provides a feeding device for assembling an adjusting screw plug of a water level sensor, comprising: a material storage barrel 10, a conveying component and a material guide bar 30.

[0026] The material storage barrel 10 is used to place the adjusting screw plug when in use. A rotating vibration disk is provided at the bottom of the material storage barrel 10. The bottom of the material storage barrel 10 is connected to the base 60, and a driving part is provided inside the base 60 for driving the rotating vibration disk to vibrate and rotate synchronously. The driving part is generally a rotating motor and a vibration motor.

[0027] The side wall of the material storage barrel 10 is provided with a spiral ascending step 11, one end of which is connected to the rotating vibration disk, and the other end is connected to the material guide bar 30. The inside of the material guide bar 30 is provided with a guide groove 31 for conveying the adjustment screw plug, and the material guide bar 30 is set in a twisted shape as a whole. Under the action of the rotating vibration disk, the adjustment screw plug inside the material storage barrel 10 moves toward the outside of the material storage barrel 10 along the spiral ascending step 11 in a way that one squeezes another. After the adjustment screw plug enters the guide groove 31 of the material guide bar 30, the posture of the adjustment screw plug is adjusted along the twisting direction of the material guide bar 30.

[0028] This setting method not only allows the adjusting screws to be automatically sorted, but also makes their final postures uniform, so that operators can install the adjusting screws as soon as they get them, without the need to calibrate the direction, saving time and improving installation efficiency.

[0029] The conveying assembly is connected to both the material storage barrel 10 and the material guide bar 30 , and is used to adjust the posture of the adjustment screw plug entering the guide groove 31 .

[0030] The conveying assembly is composed of an arc-shaped iron sheet 20 , a first guide rod 61 , a second guide rod 62 , a first air blowing pipe 41 and a second air blowing pipe 42 .

[0031] An annular rib 12 is provided at the top of the storage barrel 10, and a notch is provided on the annular rib 12. The discharge end of the spiral ascending step 11 is located at the notch, and the surface of the spiral ascending step 11 is set as a smooth plane. One end of the arc iron sheet 20 is connected to the discharge end of the spiral ascending step 11, and the other end is connected to the entrance of the guide groove 31 of the guide bar 30, and the arc iron sheet 20 is arranged downwardly along the outer wall of the storage barrel 10 to form an inclined surface, and a retaining bar 21 is provided at the lower edge of the inclined surface.

[0032] With such a configuration, when the end of the adjusting screw with the protrusion contacts the surface of the spiral ascending step 11, during the conveying process, the protrusion causes the center of gravity of the entire adjusting screw to be unstable, and thus the adjusting screw falls into the storage barrel 10. In addition, when the adjusting screw enters the arc-shaped iron sheet 20 from the spiral ascending step 11, since the arc-shaped iron sheet 20 is configured as a surface inclined toward the outer side of the outer wall of the storage barrel 10, the adjusting screw slides on the arc-shaped iron sheet 20 and stops at the stop bar 21. The adjusting screw that is misaligned due to mutual extrusion directly falls under the arc-shaped iron sheet 20, and the connection end of the arc-shaped iron sheet 20 and the spiral ascending step 11 is higher than the connection end of the arc-shaped iron sheet 20 and the guide groove 31, thereby ensuring that the adjusting screws on the arc-shaped iron sheet 20 are arranged in sequence.

[0033] The first guide rod 61 is connected to the surface of the discharge end of the spiral ascending step 11, and divides the surface of the spiral ascending step 11 into a channel for only one adjusting screw to pass through at the connection, so that the adjusting screws that move side by side on the spiral ascending step 11 are sorted out here, and only one adjusting screw passes through, ensuring that only one adjusting screw at the discharge end of the spiral ascending step 11 is discharged at a time, thereby achieving a sorting effect.

[0034] Since the arc-shaped iron sheet 20 is set as an inclined surface, and the discharge end of the spiral rising step 11 is a plane, although the connection between the arc-shaped iron sheet 20 and the spiral rising step 11 has a progressive connection transition treatment, in the process of the adjustment screw plug transferring from the plane to the inclined surface, in order to make the adjustment screw plug slide more smoothly, a second guide rod 62 is set at the connection between the arc-shaped iron sheet 20 and the spiral rising step 11. The second guide rod 62 has an arc, which is used to guide the adjustment screw plug at the discharge end of the spiral rising step 11 to the arc-shaped iron sheet 20, so that the adjustment screw plug can be transferred to the arc-shaped iron sheet 20 more smoothly and will not be separated from the arc-shaped iron sheet 20 due to too large an amplitude change.

[0035] The first air blowing pipe 41 is communicated with the inlet of the guide groove 31 , and the air blowing direction of the first air blowing pipe 41 is the same as the conveying direction of the guide groove 31 to the adjusting screw plug.

[0036] The second air blowing pipe 42 is communicated with the middle portion of the guide groove 31 , and the air blowing direction of the second air blowing pipe 42 is the same as the conveying direction of the guide groove 31 to the adjusting screw plug.

[0037] Due to the twisting of the guide strip 30, the adjusting screw plug needs power to pass smoothly through the guide groove 31. The airflow provided by the first air blowing pipe 41 and the second air blowing pipe 42 can generate suction at the entrance of the guide groove 31, so that the adjusting screw plug quickly enters the guide groove 31 and is pushed forward quickly in the guide groove 31.

[0038] The guide bar 30 is connected to the outer wall of the storage barrel 10, and the notch of the feed end of the guide groove 31 faces the side opposite to the outer wall of the storage barrel 10, and the notch of the discharge end of the guide groove 31 faces the ground. Through such a setting, the end of the adjustment screw plug with the protrusion on the arc iron sheet 20 is in a state of being in contact with the arc iron sheet 20. The protrusion of the adjustment screw plug entering the guide groove 31 is located in the notch of the guide groove 31, and slides along the torsion direction of the guide bar 30 under the push of the airflow, and is finally adjusted to a posture in which the end of the adjustment screw plug with the protrusion is downward and the end of the hexagonal screw hole is upward.

[0039] The receiving trough 50 is also included; the receiving trough 50 is installed on the outer wall of the storage barrel 10 and communicated with the inside of the storage barrel 10; the arc iron sheet 20 is located above the receiving trough 50. By providing the receiving trough 50, the adjusting screw plug dropped by the arc iron sheet 20 can be reintroduced into the storage barrel 10, which is simple and convenient.

[0040] It should be noted that if there are directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly. In addition, if there are descriptions of "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
