[0033] The specific reference is made to Figure 2 In the embodiment, the blocking mechanism 5 includes baffle 51 and opening and closing driving part 52, the baffle 51 is provided with carousel avoiding groove 53, and the opening and closing driving part 52 is connected with the baffle 51 to drive the baffle 51 to approach or away from the magnetic feeding carousel mechanism 4.

[0034] As a preferred embodiment, the baffle 51 is a lifting baffle. When the reinforcing steel bar 3 is rotated to a set position by the magnetic feeding rotary table mechanism 4, the opening and closing driving member 52 drives the baffle 51 to descend, so as to block and correct the state of the reinforcing steel bar 3. Then, the baffle 51 rises, and the reinforcing steel bar can continue to move to the side where the screening rotary table mechanism 2 is located. The structure is simple, and the reliability is good.

[0035] Further, in the embodiment, the magnetic feeding rotary table mechanism 4 comprises a feeding rotary table 41 and support rotary tables 42 arranged on both sides of the feeding rotary table 41 in the axial direction.

When the screening rotary disc 21 rotates, the reinforcing steel bars 3 on the feeding buffer seat 6 enter the respective accommodating grooves 211 one by one, and after passing through the arc-shaped stopper 22, the reinforcing steel bars 3 can be separated from the accommodating grooves 211 to supply the next station, and the structure is simple and reliable.

[0040] Embodiment two

[0041] Figure 3 Another embodiment of the reinforcing steel bar screening device is shown, and the reinforcing steel bar screening device of the embodiment is basically same as that of the embodiment one, and the difference lies in that:

[0042] In the embodiment, the baffle plate 51 is a swing baffle plate, and the opening and closing function can also be realized, the reinforcing steel bars 3 are blocked and corrected when the swing baffle plate is closed, and the swing baffle plate is opened after the reinforcing steel bars 3 reach the ideal state, and the reinforcing steel bars 3 continue to shift to the side where the screening rotary disc mechanism 2 is located.

[0043] Embodiment three

[0044] Figure 4 Another embodiment of the reinforcing steel bar screening device is shown, and the reinforcing steel bar screening device of the embodiment is basically same as that of the embodiment one and the embodiment two, and the difference lies in that:

[0045] In the embodiment, the baffle plate 51 comprises a baffle plate main body 511 and an adjusting plate 512 slidably arranged on both sides of the baffle plate main body 511, and rotary disc avoiding grooves 53 are arranged on the baffle plate main body 511 and the adjusting plate 512, the rotary disc avoiding grooves 53 on the baffle plate main body 511 are arranged in correspondence with the feeding rotary disc 41, and the rotary disc avoiding grooves 53 on the adjusting plate 512 are arranged in correspondence with the supporting rotary disc 42. The width of the baffle plate 51 can be adjusted by sliding the adjusting plate 512, the covered area is increased, the baffle plate 51 is convenient to adapt to reinforcing steel bars 3 of different lengths, and the structure is simple and effective.

[0046] The working principle of the reinforcing steel bar screening device is as follows:

[0047] The reinforcing steel bars 3 are stored on the storage seat 1, if the third material shortage detection piece 23 detects that the material is insufficient, the feeding rotary disc 41 and the supporting rotary disc 42 rotate, in the rotating process, the reinforcing steel bars 3 are attracted by the magnetic attraction pieces 411 arranged on the circumferences of the feeding rotary disc 41, so that the reinforcing steel bars 3 are brought into the screening area along with the rotation of the feeding rotary disc 41, in the process, the baffle plate 51 is in the interval area between two adjacent magnetic attraction pieces 411, that is, the blocking mechanism 5 is in the closed state, and the blocking mechanism 5 plays a role in blocking the reinforcing steel bars 3, if the corresponding reinforcing steel bars 3 are in the interval area, the reinforcing steel bars 3 are not blocked, and the reinforcing steel bars 3 are continuously transferred to the side where the screening rotary disc mechanism 2 is located. Figure 5The ideal state (i.e. substantially parallel to the rotation axis of the feeding turntable 41) is shown, the baffle 51 is opened, and the reinforcing steel bars 3 are attracted by the magnetic member 411 and brought into the screening zone.

[0048] After the reinforcing steel bars 3 are brought into the screening zone, they will roll along the second inclined surface part 62 on the feeding buffer seat 6 to the bottom and be close to the screening turntable 21.

[0049] During the rotation of the screening turntable 21, when the accommodating groove 211 is rotated to the bottom of the second inclined surface part 62, the reinforcing steel bars 3 close to the screening turntable 21 will fall into the accommodating groove 211 by gravity and rotate with the screening turntable 21. In order to screen the single reinforcing steel bar 3, the accommodating groove 211 is arranged to accommodate only the single reinforcing steel bar 3, and when the reinforcing steel bar 3 rotates to the arc-shaped blocking block 22, a small gap is formed between the reinforcing steel bar 3 and the arc-shaped blocking block 22, so that the reinforcing steel bar 3 can smoothly pass through the area of the arc-shaped blocking block 22, and the reinforcing steel bar 3 will not be out of the groove in this area.

[0050] The third material detection member 23 is arranged on the arc-shaped blocking block 22, and when the reinforcing steel bar 3 is detected, it indicates that the reinforcing steel bar 3 has been successfully fallen into the accommodating groove 211, and the screening turntable 21 stops rotating and waits for the material using signal. If the material using signal is obtained, the screening turntable 21 continues to rotate, and after the accommodating groove 211 is separated from the area of the arc-shaped blocking block 22, it can be separated from the accommodating groove 211 and fall into the next station.

[0051] Although the utility model has disclosed as above with preferred embodiments, it is not used to limit the utility model. Any skilled person in the art can make many possible changes and modifications to the technical solution of the utility model, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the utility model, by using the disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model should fall within the protection scope of the technical solution of the utility model.
