[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a steel coil unwinding machine, comprising:

[0023] A frame 1, wherein a reel 2 is rotatably arranged on the frame 1;

[0024] An adjusting unit, the adjusting unit comprises a plurality of adjusting members, the plurality of adjusting members are arranged in a circumferential ring shape on the reel 2; each adjusting member comprises a sliding rod 3 slidably embedded with the reel 2, one end of the sliding rod 3 is connected to an arc-shaped plate 4 located outside the reel 2;

[0025] A moving component is disposed in the reel 2 and is connected to a plurality of sliding rods 3 so that the plurality of sliding rods 3 can be extended or contracted on the reel 2 at the same time.

[0026] In the prior art, when the steel coil is wound, since the size of the reel 2 is fixed, it is impossible to ensure that the inner wall of the steel coils of different sizes fits tightly with the reel 2, which may affect the subsequent unwinding of the steel coil.

[0027] In order to solve the above problems, the present embodiment provides an adjustment unit so that a plurality of arc-shaped plates 4 arranged in an annular array on the outer periphery of the reel 2 can closely fit against the inner walls of steel coils of different sizes, thereby ensuring the normal winding operation.

[0028] Specifically, the detailed working process of this embodiment is as follows:

[0029] After the steel coil is placed on the reel 2, it is adjusted according to the size of the steel coil.

[0030] The moving assembly is started to drive the sliding rods 3 to extend or contract on the reel 2, thereby adjusting the distance between the reel 2 and the arc-shaped plate 4, so that the arc-shaped plates 4 are fitted and abutted against the inner wall of the steel coil.

[0031] Furthermore, the moving assembly includes a moving block 5, which is connected to a driving assembly to move the moving block 5 along the length direction of the reel 2; the moving block 5 is also circumferentially connected to a plurality of first wedge blocks 6, and each sliding rod 3 is connected to a second wedge block 7 that is matched with the corresponding first wedge block 6 at one end away from the arc plate 4; each sliding rod 3 is sleeved with a first spring 8 located between the second wedge block 7 and the side wall of the reel 2.

[0032] Specifically, when the driving assembly drives the moving block 5 to extend into the interior of the reel 2, since the second wedge block 7 is abutted against the first wedge block 6 under the action of the first spring 8, the moving block 5 then drives the first wedge block 6 to generate pressure on the second wedge block 7. Under the action of pressure, the second wedge block 7 moves horizontally toward the outside of the reel 2 to drive the sliding rod 3 to extend out of the reel 2, ultimately increasing the distance between the arc plate 4 and the reel 2; at this time, the first spring 8 is in a compressed state.

[0033] When the driving assembly drives the moving block 5 to extend outward from the reel 2, the first wedge block 6 moves. Since the first spring 8 is in a compressed state, the first wedge block 6 and the second wedge block 7 are always in contact with each other, so that the second wedge block 7 moves horizontally toward the inside of the reel 2 to drive the sliding rod 3 to retract into the reel 2, thereby finally reducing the distance between the arc plate 4 and the reel 2.

[0034] Further, the driving assembly comprises:

[0035] A screw rod 9, which is arranged in a transverse rotation in the winding drum 2 and is threadedly connected to the moving block 5, and one end of the screw rod 9 is connected to a first motor 11;

[0036] The limiting rod 10 is arranged parallel to the screw rod 9 and is slidably connected to the moving block 5 .

[0037] Specifically, the working process of the driving component in this embodiment is as follows:

[0038] First, it is known from the above embodiments that the movement of the moving block 5 can control the extension and retraction of the sliding rod 3 . The driving assembly is used to control the movement of the moving block 5 .

[0039] Specifically, the first motor 11 is started, and the first motor 11 drives the screw rod 9 to rotate. The screw rod 9 is connected to the moving thread. Since the moving block 5 in this embodiment is slidably arranged on the limit rod 10, the rotation of the moving block 5 is restricted in turn, and then the moving block 5 extends into the reel 2;

[0040] On the contrary, the first motor 11 reverses, and the first motor 11 drives the screw rod 9 to rotate in the opposite direction. The screw rod 9 is connected to the moving thread. Since the moving block 5 in this embodiment is slidably arranged on the limit rod 10, the rotation of the moving block 5 is restricted in turn, and then the moving block 5 extends out of the reel 2; finally, the normal operation of the moving assembly is guaranteed.

[0041] Furthermore, the moving block 5 moves further toward the reel 2, and four of the sliding rod 3, the arc plate 4, the first wedge block 6, the second wedge block 7 and the first spring 8 are provided.

[0042] In this embodiment, the four arc plates 4 fit the outer wall of the steel coil, which can better support and fix the steel coil; accordingly, the sliding rod 3, the first wedge plate and the second wedge plate are matched to ensure that each arc plate 4 can move simultaneously.

[0043] like Figure 3 As shown, the utility model also proposes another embodiment, the main difference between this embodiment and the above embodiment is that the frame 1 is further provided with a fixing component located on one side of the reel 2, and the fixing component includes:

[0044] A pressing plate 12, wherein the pressing plate 12 is slidably connected to the frame 1, and a pressing assembly is connected to one side of the pressing plate 12;

[0045] The roller shaft 13 is arranged on the pressure plate 12 to rotate transversely.

[0046] In order to ensure that the steel coil does not become loose during the unwinding process, a fixing component is provided in this embodiment to abut against the steel coil. Specifically, the pressing component drives the pressing plate 12 to move so that the roller 13 approaches the steel coil on the reel 2 to abut against it.

[0047] Further, the pressing assembly comprises:

[0048] A side rod 14, wherein the side rod 14 is arranged on one side of the pressing plate 12 and is mounted on the frame 1;

[0049] A rotating shaft 15 is rotatably arranged on the side rod 14 and sleeved with an eccentric wheel 16, which abuts against the pressing plate 12; a second motor is arranged at one end of the rotating shaft 15. When the second motor is started, the second motor drives the rotating shaft 15 to rotate, thereby ensuring the normal operation of the pressing assembly.

[0050] The second spring 17 is located between the side rod 14 and the pressure plate 12 .

[0051] In this embodiment, the side rod 14 is installed on the bracket to support the rotating shaft 15.

[0052] Specifically, the working process of pressing components is:

[0053] The rotating shaft 15 rotates, thereby driving the eccentric wheel 16 to rotate; the eccentric wheel 16 and one end of the pressing plate 12 always abut against each other.

[0054] When the eccentric wheel 16 abuts against the pressure plate 12 at a position far from the rotating shaft 15, the eccentric wheel 16 drives the pressure plate 12 to move toward the reel 2 and abuts against the steel coil on the reel 2, and the second spring 17 is stretched.

[0055] The eccentric wheel 16 continues to rotate, and when the eccentric wheel 16 is close to the rotating shaft 15 and abuts against the pressing plate 12, the pressing plate 12 will be reset away from the reel 2 as the eccentric wheel 16 moves under the elastic force of the second spring 17. At this time, the steel coil will be separated from the fixing of the roller 13 on the pressing plate 12.

[0056] The specific working process of the utility model is:

[0057] After the steel coil is placed on the reel 2, it is adjusted according to the size of the steel coil.

[0058] Start the first motor 11, the first motor 11 drives the screw rod 9 to rotate, the screw rod 9 is connected to the moving thread, and then drives the moving block 5 to extend into the reel 2; because the second wedge block 7 is abutted against the first wedge block 6 under the action of the first spring 8, the moving block 5 drives the first wedge block 6 to generate pressure on the second wedge block 7. Under the action of pressure, the second wedge block 7 moves horizontally toward the outside of the reel 2 to drive the sliding rod 3 to extend out of the reel 2, and finally increases the distance between the arc plate 4 and the reel 2; at this time, the first spring 8 is in a compressed state.

[0059] On the contrary, the first motor 11 rotates in the reverse direction, and the first motor 11 drives the screw rod 9 to rotate in the opposite direction, so that the moving block 5 extends out of the reel 2; thereby the first wedge block 6 moves, and since the first spring 8 is in a compressed state, the first wedge block 6 and the second wedge block 7 always abut against each other, so that the second wedge block 7 moves horizontally inside the reel 2 to drive the sliding rod 3 to contract inside the reel 2, and finally reduce the distance between the arc plate 4 and the reel 2. Finally, it can adapt to steel coils of different sizes.

[0060] After installation, the second motor is started, the rotating shaft 15 rotates, thereby driving the eccentric wheel 16 to rotate; the eccentric wheel 16 and one end of the pressing plate 12 are always in contact with each other.

[0061] When the eccentric wheel 16 abuts against the pressure plate 12 at a position far from the rotating shaft 15, the eccentric wheel 16 drives the pressure plate 12 to move toward the reel 2 and abuts against the steel coil on the reel 2, and the second spring 17 is stretched.

[0062] The eccentric wheel 16 continues to rotate, and when the eccentric wheel 16 is close to the rotating shaft 15 and abuts against the pressing plate 12, the pressing plate 12 will be reset away from the reel 2 as the eccentric wheel 16 moves under the elastic force of the second spring 17. At this time, the steel coil will be separated from the fixing of the roller 13 on the pressing plate 12.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
