[0035] As Figures 1 to 4 As shown, a feeding mechanism for a leveling machine production includes a feeding carrier 1 and a plurality of supporting vertical rods 9 vertically fixed to the top of the feeding carrier 1. A supporting top 2 is fixed on the top of the supporting vertical rods 9. The feeding mechanism for a leveling machine production also includes:

[0036] The shoveling frame 3 is slidably sleeved on the supporting vertical rod 9.

[0037] The horizontal shovel 4 is fixed relatively to one side of the shovel frame 3 and is used for shoveling round steel horizontally.

[0038] A vertical retaining bar 5 is fixed between the shovel frame 3 and the horizontal shovel 4, and is used to horizontally limit the round steel.

[0039] The lifting part 8 is arranged between the feeding carrier 1 and the support top 2. The lifting part 8 includes a threaded sleeve vertically fixed on the middle bracket 6. A vertical screw rod is rotatably provided between the support top 2 and the feeding carrier 1. The threaded sleeve is arranged on the outside of the vertical screw rod and is used to drive the servo motor to rotate the vertical screw rod. The lifting part 8 is used to drive the shoveling frame 3 to lift and lower vertically.

[0040] A middle bracket 6 is fixed on the shovel frame 3.

[0041] The scraping part 7 is provided on the middle bracket 6, and is used to scrape the round steel horizontally to the top of the horizontal shovel 4 and limit the round steel between the horizontal shovel 4 and the vertical block bar 5, and drive the scraping frame 3 to rise to a certain height by controlling the lifting part 8. The scraping frame 3 drives the horizontal shovel 4, the vertical block bar 5, the middle bracket 6, the scraping part 7 and the round steel limited between the horizontal shovel 4 and the vertical block bar 5 to rise synchronously, so as to feed the round steel to the processing position on the lathe at one time, and assist in lifting the round steel when the lathe fixes the round steel so as to fix the round steel at the processing position, killing two birds with one stone, improving the round steel feeding efficiency and reducing the difficulty of fixing the round steel on the lathe, and also being able to transport and stack the round steel when stacking the round steel.

[0042] like Figures 1 to 3 As shown, the scraping part 7 is located between the two horizontal shovels 4, and the movable end of the scraping part 7 is located outside the middle bracket 6. With this design, the round steel can be scraped to the top of the two horizontal shovels 4 along the radial direction of the round steel, and the round steel can be clamped between the movable end of the scraping part 7 and the vertical blocking bar 5 in the horizontal direction, thereby realizing the lifting and fixing of the round steel during the feeding process, and improving the stability of the round steel feeding.

[0043] like Figures 1 to 3 As shown, the top of the horizontal shovel 4 is an inclined surface, and the end of the inclined surface close to the vertical guard bar 5 is higher than the end of the inclined surface away from the vertical guard bar 5. This design can reduce the resistance to the round steel when the round steel is being pulled, so as to facilitate the round steel to be pulled to the top of the horizontal shovel 4 in the horizontal direction.

[0044] like Figures 2 to 4 As shown, the scraping portion 7 includes:

[0045] An inner sleeve rod 72 is inserted into the limiting hole 71 on the vertical surface of the middle support 6.

[0046] An outer sleeve strip 75 is fixed to one end of the inner sleeve rod 72.

[0047] A first movable joint 77 is hinged to one end of the outer sleeve strip 75.

[0048] A second movable joint 78 is hinged to the free end of the first movable joint 77.

[0049] The outer sleeve strip 75 is slidingly sleeved on the top of the middle support 6, which is located between the inner sleeve rod 72 and the outer sleeve strip 75.

[0050] In this way, the first movable joint 77 and the second movable joint 78 can be pushed away from or close to the middle support 6 by the transverse sliding of the inner sleeve rod 72, so as to first push the first movable joint 77 and the second movable joint 78 to one side of the round steel, so that the round steel is located between the first movable joint 77 and the middle support 6, then the first movable joint 77 is retracted and the round steel is simultaneously pulled close to the horizontal blade 4, until the round steel is pulled to the top of the horizontal blade 4, and the first movable joint 77 or the second movable joint 78 is in opposite abutment with the vertical blocking strip 5 on both sides of the round steel, so as to fix the round steel between the horizontal blade 4 and the vertical blocking strip 5, facilitating one-time and stable feeding of the round steel to the machining position of the lathe, improving the efficiency of round steel feeding and reducing the operation difficulty of round steel feeding.

[0051] As shown in Figure 2 and Figure 3 , the first movable joint 77 is located at the end of the outer sleeve strip 75 away from the middle support 6, and the bottom of the second movable joint 78 is level with the top of the horizontal blade 4.

[0052] The vertical surface of the first movable joint 77 and the second movable joint 78 close to the top of the middle support 6 is a 90° circular arc, and the top and bottom of the first movable joint 77 and the second movable joint 78 are horizontal surfaces.

[0053] In this way, the first movable joint 77 and the second movable joint 78 can only be deflected towards the middle support 6, and the upper limit of the deflection angle is 90°, so that when the inner sleeve rod 72 is pushed out, the first movable joint 77 and the second movable joint 78 can smoothly pass over the top of the round steel, and when it is pulled back, the first movable joint 77 and the second movable joint 78 can be in a vertical state, and simultaneously pull the round steel close to the horizontal blade 4, efficiently completing the loading of the round steel.

[0054] As shown in Figure 3 and Figure 4 , the material scraping part 7 further comprises:

[0055] The horizontal wire rod 74 is arranged in the limiting hole 71 and rotates axially, one end of the horizontal wire rod 74 is screwed with the middle threaded hole 73 arranged on the vertical surface of the inner sleeve rod 72.

[0056] The driving member 76 is arranged on the middle support 6, the driving member 76 includes a driving motor fixed on the middle support 6 and two spur gears respectively fixed on the output end of the driving motor and one end of the horizontal wire rod 74, the transmission chain is sleeved between the two spur gears, the driving member 76 is used for driving the horizontal wire rod 74 to rotate, so the design can realize the mechanical loading of round steel and reduce the labor intensity of the operator.

[0057] Working principle: push the feeding carrier 1 along the horizontal radial direction of the round steel to approach the round steel, and make the distal end of the horizontal shovel 4 face the round steel, and control the lifting part 8 to drive the shovel carrier 3 to descend to a certain height, so that the lowest part of the top of the horizontal shovel 4 approaches the bottom of the round steel, and then control the driving part 76 to drive the horizontal screw rod 74 to rotate forward, so that the inner sleeve rod 72 extends to a certain length outside the limiting hole 71, so that the first movable joint 77 and the second movable joint 78 approach the round steel and completely pass over the top of the round steel to the other side of the round steel. At this time, the first movable joint 77 and the second movable joint 78 are in a natural vertical state under the action of gravity, and in the process, the first movable joint 77 and the second movable joint 78 are deflected from bottom to top and towards the direction of the middle support 6. After the first movable joint 77 and the second movable joint 78 completely pass over the top of the round steel, control the driving part 76 to reverse and drive the horizontal screw rod 74 to rotate reversely, so that the inner sleeve rod 72 shrinks into the limiting hole 71, and pulls the first movable joint 77 and the second movable joint 78 close to the round steel, until the first movable joint 77 or the second movable joint 78 abuts against the outside of the round steel. With the continuous shrinking of the inner sleeve rod 72, the round steel is pulled towards the top of the horizontal shovel 4 at the same time, until the side of the round steel close to the shovel carrier 3 abuts against one side of the vertical baffle 5, and the two ends of the round steel are respectively between the two groups of horizontal shovels 4 and vertical baffles 5, and the round steel is clamped in the horizontal radial direction between the first movable joint 77 in vertical state and the vertical baffle 5. Then push the feeding carrier 1 close to the lathe, when it approaches the lathe, control the lifting part 8 to drive the shovel carrier 3 to rise to a certain height. When the shovel carrier 3 rises, it will drive the horizontal shovel 4, the vertical baffle 5, the middle support 6, the scraping part 7 and the round steel to rise synchronously, so as to convey the round steel to the machining station of the lathe and statically hold the round steel, until the round steel is fixed on the machining station of the lathe. Then control the driving part 76 to drive the inner sleeve rod 72 to extend, until the distance between the first movable joint 77 and the round steel is greater than the total length of the first movable joint 77 and the second movable joint 78. Then the staff manually pulls the second movable joint 78 to deflect, and makes one side of the first movable joint 77 and the second movable joint 78 completely adhere to the bottom of the inner sleeve rod 72. Finally, control the driving part 76 to drive the inner sleeve rod 72 to shrink, until the second movable joint 78 passes over the top of the round steel, then the second movable joint 78 can be released. With the continuous shrinking of the inner sleeve rod 72, until the first movable joint 77 and the second movable joint 78 completely pass over the top of the round steel, the effect of efficient feeding of the round steel and auxiliary fixing operation before round steel processing is realized, and the round steel feeding operation can be prepared again.
