DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] like Figures 1 to 3 As shown, a round bar material distribution and feeding mechanism includes a conveyor belt 1 for conveying bar materials, a material box 2 arranged at the rear end of the conveyor belt 1, and a positioning mechanism arranged on the conveyor belt 1 for spacing and positioning the bar materials. The bottom of the material box 2 is provided with a material shifting mechanism for ensuring smooth dropping of the round bars; the conveyor belt 1 is driven by a motor belt, which is a prior art and will not be described in detail here.

[0030] During operation, the metal round bars in the material box 2 fall onto the conveyor belt 1 in sequence and are transported forward by the conveyor belt 1. In this process, the positioning mechanism positions the two round bars at the front end of the conveyor belt 1, ensuring a compact feeding rhythm of the metal round bars and preventing the round bars from piling up or the processing mechanism from waiting for the material.

[0031] As Figure 3 shown, the stock feeding mechanism includes a rotating shaft 3 arranged at the bottom of the stock bin 2 and stock feeding wheels 4 symmetrically arranged on the rotating shaft 3. Both ends of the rotating shaft 3 are rotatably connected to the bottom of the stock bin 2 through bearings. A plurality of stock feeding teeth 5 are evenly arranged on the outer cylindrical surface of the stock feeding wheel 4. An opening 6 is arranged at a position corresponding to the stock feeding teeth 5 at the bottom of the stock bin 2. A first motor 7 for driving the rotating shaft 3 to rotate is arranged on the side surface of the stock bin 2.

[0032] The first motor 7 drives the rotating shaft 3 to rotate. Under the action of the stock feeding teeth 5 on the stock feeding wheel 4, the metal round bars in the stock bin 2 are continuously combed, so that the metal round bars are conveyed more smoothly and the discharge port will not be blocked. The stock feeding wheels 4 arranged symmetrically on the left and right make the metal round bars receive balanced forces.

[0033] As Figure 3 shown, an inclined surface 8 is arranged at the lower end of the stock bin 2, and the opening 6 is arranged on the inclined surface. The inclined surface 8 can ensure that the round bars in the stock bin completely fall into the discharge port at the bottom.

[0034] As Figure 1 shown, a discharge port 9 is arranged at a position corresponding to the conveyor belt 1 at the bottom of the stock bin 2.

[0035] As Figure 1 and Figure 4 shown, the positioning mechanism includes a rotating frame arranged on the bracket of the conveyor belt 1 and rotatable on the bracket. The rotating frame includes a first cross beam 10 at the upper end and a second cross beam 11 at the lower end. The length of the first cross beam 10 is greater than the length of the second cross beam 11, and the length difference between the two is the diameter length of the round bar. Connecting rods 12 are arranged at the ends of the first cross beam 10 and the second cross beam 11. Positioning rods 13 are arranged at the lower end of the upper connecting rod 12 and the upper end of the lower connecting rod 12. In this embodiment, three positioning rods 13 are arranged on each connecting rod 12. The conveyor belts 1 are symmetrically distributed on the left and right. The positioning rods 13 extend into the space between the two conveyor belts. A first driving mechanism for driving the rotating frame to swing up and down is arranged on the bracket of the conveyor belt 1. During operation, the first driving mechanism continuously drives the rotating frame to swing up and down. When the rotating frame rotates to the highest position, when the positioning rod 13 at the end of the first cross beam 10 separates from the foremost round bar, at this time, the positioning rod 13 at the end of the second cross beam 11 blocks the second round bar, and the conveyor belt can convey the foremost round bar forward. Then the rotating frame swings downward until it swings to the lowest position. At this time, the positioning rod 13 at the end of the second cross beam 11 separates from the second round bar, and the second round bar moves forward, and the positioning rod 13 at the end of the first cross beam 10 blocks the round bar. In this way, it circulates repeatedly, realizing the sequential forward movement of the round bars, ensuring that the feeding rhythm of the round bars is compact, and preventing the round bars from piling up or the processing mechanism waiting for materials. The positioning of the foremost two metal round bars can be realized by the swing of the rotating frame, and the structure is simple and the cost is low.

[0036] The first driving mechanism comprises a second motor 14 arranged on the support of the conveyor belt 1. The output end of the second motor 14 is provided with a cam 15 matched with the bottom of the second beam 11. The second motor 14 drives the cam 15 to rotate, thereby driving the rotating frame to swing continuously.

[0037] A tension spring 16 is provided between the second cross beam 11 and the support of the conveyor belt 1 , and the tension spring 16 can ensure that the second cross beam 11 at the lower end of the rotating frame is always closely matched with the cam 15 , and the rotating frame swings reliably.

[0038] Embodiment 2:

[0039] like Figure 5 and Figure 6 As shown, the positioning mechanism includes a mounting frame 17 mounted on the support of the conveyor belt 1, a positioning slot 18 arranged in the mounting frame 17 and swinging in the mounting frame 17, the positioning slot 18 is in an inverted U shape, a rotating shaft is provided at the upper end of the positioning slot 18, the rotating shaft and the mounting frame 17 are rotatably connected through a bearing, and a second driving mechanism for driving the positioning slot 18 to swing back and forth is provided on the mounting frame 17. When the second driving mechanism drives the positioning slot 18 to swing backward to the limit position, the side plate at the front end of the positioning slot 18 cooperates with the metal round bar at the front end, and the side plate at the rear end of the positioning slot 18 is separated from the metal round bar. After that, the second driving mechanism drives the positioning slot 18 to swing forward to the limit position, at which time the side plate at the front end of the positioning slot 18 is separated from the metal round bar at the front end, the metal round bar at the front end is transported forward with the conveyor belt, and the side plate at the rear end of the positioning slot 18 blocks the second metal round bar. The cycle is repeated, thereby realizing the sequential forward conveying of the metal round bars, ensuring the stable feeding rhythm of the metal round bars.

[0040] The second driving mechanism includes a cylinder 19, a driving rod 20 is provided at the upper end of the positioning groove 18, the cylinder body end of the cylinder 19 is rotatably connected to the mounting frame 17, and a sleeve 21 that cooperates with the driving rod 20 is provided at the piston rod end of the cylinder 19. The extension and retraction of the piston rod of the cylinder 19 drives the positioning groove 18 to swing back and forth.

[0041] Limiting rods 22 are symmetrically arranged on both sides of the positioning slot 18 in the mounting frame 17 , and the limiting positions of the positioning slot 18 for swinging forward and backward are limited by the limiting rods 22 , so the reliability is good.
