The provision of the transition plate 6 can facilitate the transmission of the straightened coil to the next process.

[0030] like Figure 1 and Figure 5 As shown, in this embodiment, a first fixed shaft 25 is provided at each of the four top corners of the leveling frame 21, and the first driving assembly 24 includes two driving units, each of which includes a first driver 241 and a transmission 242 located on both sides of the first driver 241, and a first transmission shaft 244 is provided between the first driver 241 and the two transmissions 242 of each driving unit, and both ends of each first transmission shaft 244 are transmission-connected with the transmission 242 through a first coupling 246, and a connecting rod 245 is fixedly provided between the top of a transmission 242 in a driving unit and the top of a transmission 242 in another driving unit on the same side, and the bottom of the transmission 242 is fixedly connected to the top of the leveling frame 21; the first driving assembly 24 also includes a second driver 243, and the top of a second driver 243 is fixedly connected to a corresponding connecting rod 245; and the number of the second drivers 243 is equal to the number of the connecting rods 245.

Through the driving action of the first driver 241, the first transmission shaft 244 is driven to rotate, thereby driving the lifting screw to rotate. Since the lifting screw is fixed in the vertical direction by the first fixed shaft 25 and the first transmission shaft 244, the lifting reducer will be lifted relative to the lifting screw when the lifting screw rotates, thereby driving the leveling frame 21 to lift and lower, so that the first straightening roller assembly fixedly connected to the leveling frame 21 is lifted and lowered to adjust the distance between the first straightening roller assembly and the second straightening roller assembly. The second driver 243 is set to drive the connecting rod 245 to move up and down, thereby driving the transmission devices 242 on both sides to move up and down, so as to eliminate the gap generated by the transmission devices 242 on both sides of each driving unit during transmission.

[0031] In this embodiment, a first sensor 81 is fixedly provided on the side of the leveling frame 21 close to the material guiding mechanism 3, and a second sensor 82 is fixedly provided on the side close to the transition plate 6. The first sensor 81 is used to receive the signal of the incoming coil after uncoiling, and confirm that the coil begins to enter the straightening mechanism 2. The second sensor 82 is used to receive the signal transmitted outward from the discharge port after the coil is straightened.

[0032] Furthermore, if Figure 4 and Figure 5As shown, the feed mechanism 3 includes a first feed roller assembly, a second feed roller assembly and a second driving assembly 37 for driving the first feed roller assembly to descend in a vertical direction. The first feed roller assembly includes a first feed roller 31 and a first fixed seat 32 located at both ends of the first feed roller 31; the second feed roller assembly includes a second feed roller 33 and a second fixed seat 34 located at both ends of the second feed roller 33, the bottom of the second fixed seat 34 is fixedly connected to the top of the frame 1, the first feed roller 31 is rotatably connected to the first fixed seat 32, and the second feed roller 33 is rotatably connected to the second fixed seat 34; the first feed roller 31 is parallel to the second feed roller 33 and is located directly above the second feed roller 33. The second driving assembly 37 is fixedly connected to the top of the first fixed seat 32.

The second fixed shaft 35 is perpendicular to the first feed roller 31. In addition, the second driving assembly 37 includes a first transmission rod, one end of which is fixedly connected to one end of the second fixed shaft 35 away from the second fixed seat 34. When the second driving assembly 37 drives the first transmission rod to extend, it can drive the first fixed seat 32 to descend, thereby driving the first feed roller 31 to descend, so that the first feed roller 31 is pressed on the surface of the incoming coil.

[0033] An elastic member 36 is also provided between the bottom of the first fixed seat 32 and the top of the second fixed seat 34. The elastic member 36 is always in a compressed state. The second driving assembly 37 of this embodiment is preferably a cylinder. The upper end air port of the cylinder is an air inlet, and the lower end air port does not have air intake, but only a muffler to eliminate noise. Therefore, when the air inlet intakes air, the first transmission rod will extend and push the first fixed seat 32 downward, so that the first feeding roller 31 is pressed downward to press the surface of the coil; since the first feeding roller 31 has a large deadweight, the elastic member 36 is provided to provide an upward force for the first fixed seat 32 to support the first fixed seat 32, thereby supporting the first feeding roller 31. The elastic member 36 of this embodiment is preferably a spring.

[0034] Furthermore, the driving mechanism 5 is used to drive the first feeding roller 31, the second feeding roller 33, the first straightening roller 221 and the second straightening roller 231 to rotate simultaneously to straighten the coil. Figure 1 and Figure 5As shown, the driving mechanism 5 includes a base 51 located on one side of the frame 1, a fourth driving assembly 52 fixedly connected to the base 51, and a transmission assembly connected to the fourth driving assembly 52. ​​The fourth driving assembly 52 includes a motor 521 and a reducer 522, the reducer 522 is fixed on the base 51, and the motor 521 is fixed on the reducer 522.

The first gear C1 is meshed with the second gear C2 and the third gear C3 at the same time to achieve transmission, and the second gear C2 is meshed with two fourth gears C4 at the same time to achieve transmission, and the two fourth gears C4 are respectively arranged corresponding to the positions of the first feed roller 31 and the second feed roller 33; the third gear C3 is meshed with a fifth gear C5, and there are 11 fifth gears C5 in total, of which 5 fifth gears C5 correspond to the positions of the 5 first straightening rollers 221, and the remaining 6 fifth gears C5 correspond to the positions of the 6 second straightening rollers 231.

[0035] The transmission assembly also includes a third transmission rod 533, wherein the third transmission rod 533 is provided between one end of the first feed roller 31 and a fourth gear C4, between the second feed roller 33 and another fourth gear C4, and between the first straightening roller 221 and a corresponding fifth gear C5, and between the second straightening roller 231 and a corresponding fifth gear C5. The fourth driving assembly 52 drives the first gear C1 to rotate through the second coupling 531, thereby driving the second gear C2 and the third gear C3 to rotate, and then driving the fourth gear C4 and the fifth gear C5 to rotate respectively, so that the first feed roller 31 and the second feed roller 33 rotate accordingly, and the first straightening roller 221 and the second straightening roller 231 also rotate accordingly.

[0036] Furthermore, if Figure 5As shown, the material blocking mechanism 4 is located on the side of the material feeding mechanism 3 away from the straightening mechanism 2, and the material blocking mechanism 4 includes a second transmission shaft 42, a third fixed seat 44 located at both ends of the second transmission shaft 42, two slides 45 slidably sleeved on the outer periphery of the second transmission shaft 42, and a material blocking roller 41 fixedly arranged on the top of the slide 45, the two slides 45 are located between the two third fixed seats 44, and the material blocking roller 41 is parallel to the first material feeding roller 31. In this embodiment, two material blocking rollers 41 are arranged on the top of each slide 45. The material blocking rollers 41 on the two slides 45 can ensure that the coil remains stable during the transmission and straightening process without deviation. The material blocking mechanism 4 further includes a second transmission rod 43, a fourth fixed seat 46, and a third driving assembly 49 for driving the second transmission rod 43 to rotate. The second transmission rod 43 is located directly above the second transmission shaft 42 and is parallel to the second transmission shaft 42. The second transmission shaft 42 and the second transmission rod 43 both penetrate the thickness direction of the fourth fixed seat 46, and the fourth fixed seat 46 is arranged at the center of the second transmission rod 43 and the second transmission shaft 42.

Under the driving action of the third driving assembly 49, the second transmission rod 43 will rotate, so that the two slide seats 45 at both ends will slide toward each other relative to the second transmission rod 43, so as to adjust the distance between the material blocking rollers 41 at both ends to match the width of the coiled material after unwinding. In this embodiment, the second transmission rod 43 is preferably a positive and negative threaded screw, and a bearing is arranged on the outer periphery of the connection between the second transmission rod 43 and the fourth fixed seat 46, so that when the second transmission rod 43 rotates, the second transmission rod 43 can rotate relative to the fourth fixed seat 46, but the position of the fourth fixed seat 46 on the second transmission rod 43 remains unchanged.

[0037] A first support seat 47 is fixedly disposed on the top surface of each slide seat 45, and a second support seat 48 is fixedly disposed on the top surface of the fourth fixed seat 46.

[0038] The working process of the coil straightening device of the utility model is as follows:

[0039] After the metal coil is unrolled and before straightening, the leveling frame 21 is raised and lowered under the driving action of the first driver 241, so as to adjust the distance between the first straightening roller 221 and the second straightening roller 231; then, the first feed roller 31 is driven downward under the driving action of the second drive assembly 37 to ensure that it can press the surface of the coil, and at the same time, according to the thickness of the coil, the third drive assembly 49 is started to adjust the distance between the two stop rollers 41 on the slide 45 to match the width of the coil. After the adjustment is completed, the second driver 243 is activated to apply a downward pressure to the first straightening roller assembly to eliminate the matching clearance between the lifting transmission 242 and its lifting screw. Subsequently, the fourth drive assembly 52 is started to drive the first feed roller 31 and the second feed roller 33 as well as the first straightening roller 221 and the second straightening roller 231 to rotate to straighten the coil.
