[0029] The present utility model will be described in detail below with reference to the accompanying drawings.

[0030] As Figures 1 to 3 shown, a metal coil leveling and feeding mechanism of the present utility model includes a frame 1, a feeding device 2 arranged on the frame 1, a flattening device 3 cooperating with the feeding device 2, and a feeding device 4 cooperating with the flattening device 3. The flattening device 3 includes a fixed frame 31 arranged on the frame 1, a movable frame 32 movably arranged on the frame 1, an upper flattening roller 33 rotatably arranged between the movable frame 32 and the fixed frame 31, and a lower flattening roller 34 arranged at an interval from the upper flattening roller 33. The movable frame 32 approaches or moves away from the fixed frame 31 to adjust the distance between the movable frame 32 and the fixed frame 31.

[0031] Before working, first drive the movable frame 32 to approach the fixed frame 31 according to the width dimension of the metal coil to adjust the distance between the movable frame 32 and the fixed frame 31, with good adjustment effect. Then, install the upper flattening roller 33 and the lower flattening roller 34 with corresponding specifications and sizes. When the metal coil reaches the flattening device 3 through the transportation of the feeding device 2, the upper flattening roller 33 rolls and abuts against the upper surface of the metal coil. At the same time, the lower flattening roller 34 rolls and abuts against the lower surface of the metal coil. By the upper and lower pressing action of the upper flattening roller 33 and the lower flattening roller 34, the flat state of the metal coil is maintained. Finally, the flattened metal coil is transported to the subsequent processing process through the feeding device 4. The present utility model effectively applies to metal coils of different width specifications by adjusting the distance between the movable frame and the fixed frame, has a wide application range, improves the utilization rate of the leveling machine, and reduces the production cost.

[0032] A nut 35 is provided at the top of the movable frame 32 in this embodiment. A first bearing 36 and a second bearing 37 are provided at the bottom of the movable frame 32. A driving motor 38 is provided on the machine frame 1. The output end of the driving motor 38 is drivingly connected with a coupling 39. A screw rod 310 connected to the coupling 39 is provided on the fixed frame 31. The movable frame 32 is sleeved outside the screw rod 310 through the nut 35 in a threaded manner, so that the movable frame 32 moves along the length direction of the screw rod 310. The first bearing 36 and the second bearing 37 are respectively connected to the upper flattening roller 33 and the lower flattening roller 34. Specifically, the driving motor 38 drives the screw rod 310 to rotate through the coupling 39. The rotating screw rod 310 drives the nut 35 to move. Since the nut 35 is connected to the movable frame 32, the movable frame 32 is driven to move along the length direction of the screw rod 310, effectively adjusting the distance between the movable frame 32 and the fixed frame 31. The adjustment is simple and convenient. The first bearing 36 and the second bearing 37 are respectively connected to the upper flattening roller 33 and the lower flattening roller 34, which helps the upper flattening roller 33 and the lower flattening roller 34 to rotate stably and smoothly, reduces the friction resistance, and prolongs the service life of the upper flattening roller 33 and the lower flattening roller 34.

[0033] An installation seat 311 is provided at the top of the fixed frame 31 in this embodiment. A third bearing 312 and a fourth bearing 313 are provided at the bottom of the fixed frame 31. The installation seat 311 is connected to the screw rod 310. The third bearing 312 and the fourth bearing 313 are respectively connected to the other ends of the upper flattening roller 33 and the lower flattening roller 34. An expansion rod 314 is provided between the fixed frame 31 and the movable frame 32. Specifically, the fixed frame 31 is connected to the screw rod 310 through the installation seat 311, so that the driving motor 38 can be drivingly connected to the screw rod 310 through the coupling 39. The third bearing 312 and the fourth bearing 313 are respectively connected to the upper flattening roller 33 and the lower flattening roller 34, which helps the upper flattening roller 33 and the lower flattening roller 34 to rotate stably and smoothly, reduces the friction resistance, and prolongs the service life of the upper flattening roller 33 and the lower flattening roller 34. An expansion rod 314 is provided between the fixed frame 31 and the movable frame 32. The expansion rod 314 is a prior art. It is a telescopic hollow cylinder rod made of metal strip or plastic sheet. Its feature is that the metal strip or plastic sheet is pre-shaped into an elastic curly layer with a memory function smaller than the outer diameter of the rod body, so as to have a self-tightening function, so that the curly layer always has an elastic potential energy applying pressure to the expansion rod 314, and better fixes the positions of the movable frame 32 and the fixed frame 31 after adjusting the position.

[0034] The feeding device 4 of this embodiment includes a vertical frame 41, a U-shaped frame 42 movably arranged on the vertical frame 41, an upper feeding roller 43 rotatably connected to the U-shaped frame 42, a lifting cylinder 44 drivingly connected to the U-shaped frame 42, a lower feeding roller 45 arranged at an interval from the upper feeding roller 43, and a servo motor 46 drivingly connected to the lower feeding roller 45. A first synchronous pulley 47 is arranged on the outer side of the lower feeding roller 45, a second synchronous pulley 315 is arranged outside the lower pressing and flattening roller 34, and a synchronous belt 48 is drivingly connected between the first synchronous pulley 47 and the second synchronous pulley 315. A feeding wheel 49 is rotatably arranged on the outer side of the vertical frame 41. Specifically, the servo motor 46 drives the upper feeding roller 43 to approach the lower feeding roller 45 through the U-shaped frame 42, the servo motor 46 drives the lower feeding roller 45 to rotate, the rotating lower feeding roller 45 transports the metal coil forward, and the lower feeding roller 45 drives the synchronous belt 48 to rotate through the first synchronous pulley 47. The rotating synchronous belt 48 further drives the second synchronous pulley 315 to rotate. Since the second synchronous pulley 315 is connected to the lower pressing and flattening roller 34, the lower pressing and flattening roller 34 is driven to rotate. The transmission efficiency is high, which helps the upper feeding roller 43 and the lower feeding roller 45 to clamp the metal coil up and down and transport it smoothly, and then the metal coil is transported to the subsequent processing procedure through the feeding wheel 49.

[0035] A plurality of lower pressing and flattening rollers 34 are arranged at intervals in this embodiment, and transmission gears 316 are arranged at the ends of the plurality of lower pressing and flattening rollers 34, and adjacent two transmission gears 316 are meshed with each other. Specifically, as a preference, three lower pressing and flattening rollers 34 are arranged. A second synchronous pulley 315 is arranged outside one of the lower pressing and flattening rollers 34 close to the feeding device 4. The first synchronous pulley 47 drives the synchronous belt 48 to rotate, and the rotating synchronous belt 48 further drives the second synchronous pulley 315 to rotate, thereby driving one of the lower pressing and flattening rollers 34 to rotate. The rotating one of the lower pressing and flattening rollers 34 drives the adjacent two lower pressing and flattening rollers 34 to rotate by means of the meshing transmission of the transmission gears 316, and then realizes the meshing rotation of the three lower pressing and flattening rollers 34 to transport the metal coil.

[0036] The feeding device 2 of this embodiment includes two brackets 21 arranged at intervals, a moving seat 22 movably arranged on the brackets 21, a driving cylinder 23 drivingly connected to the moving seat 22, an upper feeding roller 24 rotatably arranged on the moving seat 22, and a lower feeding roller 25 rotatably arranged on the brackets 21. The upper feeding roller 24 is driven by the driving cylinder 23 to approach or move away from the lower feeding roller 25. The moving seat 22 is provided with a disc spring 26. One end of the disc spring 26 abuts against the output end of the driving cylinder 23, and the other end of the disc spring 26 abuts against the moving seat 22. Specifically, the driving cylinder 23 drives the upper feeding roller 24 to approach the lower feeding roller 25 through the moving seat 22, which helps to roll and transport the metal coil between the upper feeding roller 24 and the lower feeding roller 25. The disc spring abuts against the output end of the driving cylinder 23 and the moving seat 22 respectively, effectively limiting the up and down movement area of the moving seat 22. The disc spring has a large stiffness and strong buffering and vibration absorption ability, and can withstand large loads with small deformations, which is suitable for occasions with small axial space requirements.
