[0037] Please also read Figures 1 to 5, the roller device for preventing the steel coil from being shaken apart and loosened provided by the embodiment of the utility model is now described. The roller device for preventing the steel coil from being shaken apart and loosened provided by the embodiment of the utility model comprises a pressing roller mechanism 1 and a pressing roller mechanism 2. The pressing roller mechanism 2 and the pressing roller mechanism 1 are respectively mounted on the machine platform 3 in a matching manner. The pressing roller mechanism 1 and the pressing roller mechanism 2 are arranged at intervals along the circumference of the winding shaft 61, and the distance between the first pressing roller 13 of the pressing roller mechanism 1 and the second pressing roller 23 of the pressing roller mechanism 2 is less than or equal to one-fourth of the circumference of the winding shaft 61, which is conducive to better overcoming the elastic force generated by the bending deformation of the outer layer of the steel coil. The pressing roller mechanism 2 is used to press the outer layer of the steel coil to form a bundle during the process of winding the steel coil, and the pressing roller mechanism 1 is used to press and position the tail end or tail section of the steel coil before the tail end of the steel coil passes over the pressing roller mechanism 2. Specifically, the pressing roller mechanism 1 includes a first rotating shaft 11 rotatably installed on the machine table 3, a first driving mechanism 12 for driving the first rotating shaft 11 to rotate, a first pressing roller 13 for pressing the tail end of the steel coil, and a first pressing arm 14 for driving the first pressing roller 13 to swing and switch between a pressing position and a non-pressing position. The first end of the first pressing arm 14 is connected to the first rotating shaft 11, and the second end of the first pressing arm 14 is a suspended end. The first pressing roller 13 is rotatably arranged at the suspended end of the first pressing arm 14. When the pressing roller device is used for pressing, the pressing roller mechanism 2 applies pressure to the outer steel plate of the coil on the winding shaft 61 to make the winding more compact. At the same time, the first rotating shaft 11 is driven to rotate in the first direction by the first driving mechanism 12, and the first rotating shaft 11 drives the first pressing arm 14 to rotate until the first pressing arm 14 drives the first pressing roller 13 and keeps it in the pressing position. Under the action of the pressing force provided by the first driving mechanism 12 and the first pressing arm 14, the first pressing roller 13 can cooperate with the pressing roller mechanism 2 to stably press the steel coil on the winding shaft 61, effectively overcoming the elastic force generated by the bending deformation of the outer steel plate of the coil. In addition, before the tail end of the steel coil passes over the pressing roller mechanism 2, the tail end or tail section of the steel coil can be pressed and positioned by the first pressing roller 13 of the pressing roller mechanism 1, effectively preventing the tail end or tail section of the steel coil from passing over the pressing roller mechanism 2.

[0038] Compared with the prior art, the roller device for preventing the steel coil from being shaken apart and becoming loose is provided in the embodiment of the utility model. When the flexible rolled plate winding device is winding, the pressure is applied to the outer steel plate of the steel coil on the winding shaft 61 by the pressure roller mechanism 2 to make the winding more compact. At the same time, the pressure is applied to the outer steel plate of the steel coil by the pressure roller mechanism 1 to overcome the elastic force generated by the bending deformation of the outer steel plate of the steel coil, and the pressure applied to the outer steel plate of the steel coil on the winding shaft 61 is further enhanced, so as to ensure that the flexible rolled plate winding device can be wound efficiently and smoothly. In addition, before the tail end of the steel coil passes over the pressure roller mechanism 2, the tail end or tail section of the steel coil can be pressed and positioned by the first pressure roller 13 of the pressure roller mechanism 1, so as to effectively prevent the tail end or tail section of the steel coil from passing over the pressure roller mechanism 2, thereby preventing the tail end or tail section of the steel coil from stretching into a flat plate due to the loss of the pressing force, and preventing the steel coil from popping out of the workstation and shaking apart instantly under the action of the elastic force, thereby causing loose materials, damaging the equipment or injuring the staff.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the pressing roller mechanism 1 further includes a second driving mechanism 15 for driving the first pressing roller 13 to rotate, and the second driving mechanism 15 includes a first motor 151 provided on the first pressing arm 14 at a position corresponding to the first pressing roller 13, and the output shaft of the first motor 151 is connected to the first pressing roller 13. When the pressing roller mechanism 1 is used for pressing, it is only necessary to drive the first pressing roller 13 to rotate by the first motor 151, so that rolling friction is generated between the first pressing roller 13 and the outer steel plate of the coil, and the friction between the first pressing roller 13 and the outer steel plate of the coil is effectively reduced, so as to ensure that the flexible rolled plate winding equipment can perform winding work efficiently and smoothly. At the same time, by driving the first pressing roller 13 to rotate by the first motor 151, additional power can be provided for the coil in the winding process, and the working efficiency of the flexible rolled plate winding equipment can be effectively improved.

[0040] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the first motor 151 is a bidirectional hydraulic motor, and the second driving mechanism 15 also includes a protective cover 152 arranged on the first pressing arm 14. The first motor 151 is installed in the protective cover 152, which can protect the first motor 151.

[0041] Please refer to Figure 1 , Figure 2 and Figure 5In some embodiments, the first pressing roller 13 includes a first pressing roller shaft 131 rotatably mounted on the first pressing arm 14 and a first pressing roller sleeve 132 sleeved on the first pressing roller shaft 131. The axial direction of the first pressing roller shaft 131 is parallel to the axial direction of the first rotating shaft 11, and the length direction of the first pressing arm 14 is perpendicular to the axial direction of the first rotating shaft 11. In addition, when the first pressing arm 14 drives and maintains the first pressing roller 13 at the pressing position, the first pressing arm 14 is arranged horizontally. Under the driving force of the first driving mechanism 12 and the gravity of the first pressing arm 14, the first pressing roller 13 can stably press the steel coil on the winding shaft 61.

[0042] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the pressing roller mechanism 1 further includes a first swing arm 16, a first end of the first swing arm 16 is connected to the first rotating shaft 11, and a second end of the first swing arm 16 is connected to a power output end of the first driving mechanism 12. Since the first end of the first swing arm 16 is connected to the first rotating shaft 11, and the second end of the first swing arm 16 is connected to the power output end of the first driving mechanism 12, when the first driving mechanism 12 drives the first swing arm 16 to swing around the first rotating shaft 11, a lever movement effect can be formed, which can enhance the force of the first rotating shaft 11 driving the first pressing arm 14 to rotate, and is conducive to increasing the pressing force transmitted by the first pressing arm 14 to the first pressing roller 13, which is conducive to the first pressing roller 13 to stably press or position the outer steel plate of the steel coil.

[0043] Please refer to Figure 1 , Figure 2 and Figure 4 In some of the embodiments, in order to further increase the pressing force of the first pressing roller 13 on the outer steel plate of the steel coil, the first driving mechanism 12 is a first hydraulic cylinder, the cylinder body of the first hydraulic cylinder is used to be hinged with the machine table 3, and the piston rod of the first hydraulic cylinder is hinged with the second end of the first swing arm 16.

[0044] Please refer to Figure 2 , Figure 3 and Figure 5In some embodiments, the press roller mechanism 2 includes a second rotating shaft 21, a third driving mechanism 22, a second press roller 23, a second press arm 24 and a fourth driving mechanism 25. The second rotating shaft 21 is rotatably mounted on the machine platform 3 through a bearing and a bearing seat. The third driving mechanism 22 is mounted on the machine platform 3 at a position corresponding to the second rotating shaft 21. The power output end of the third driving mechanism 22 is connected to the second rotating shaft 21, so that the third driving mechanism 22 can drive the second rotating shaft 21 to rotate. The second press roller 23 is used to press the steel coil on the winding shaft 61. The first end of the second press arm 24 is connected to the second rotating shaft 21. The second end of the second press arm 24 is a suspended end. The second press roller 23 is rotatably arranged at the suspended end of the second press arm 24. The second press arm 24 can drive the second press roller 23 to swing and switch between the pressing position and the non-pressing position. The fourth driving mechanism 25 is arranged on the second pressing arm 24 at a position corresponding to the second pressing roller 23, and the fourth driving mechanism 25 is connected to the second pressing roller 23, and the second pressing roller 23 can be driven to rotate by the fourth driving mechanism 25. When the pressing roller mechanism 2 is used for pressing, the third driving mechanism 22 can drive the second rotating shaft 21 to rotate along the first direction, and the second rotating shaft 21 drives the second pressing arm 24 to rotate until the second pressing arm 24 drives the second pressing roller 23 and keeps it at the pressing position, and under the pressing force provided by the third driving mechanism 22 and the second pressing arm 24, the second pressing roller 23 can stably press the steel coil on the winding shaft 61. When the second nip roller 23 presses against the steel coil on the winding shaft 61 and applies too much pressure to the outer steel plate of the steel coil, the fourth driving mechanism 25 drives the second nip roller 23 to rotate, so that rolling friction is generated between the second nip roller 23 and the outer steel plate of the steel coil. Compared with the sliding friction generated between the second nip roller 23 and the outer steel plate of the steel coil, the friction between the second nip roller 23 and the outer steel plate of the steel coil is significantly reduced, which can ensure that the flexible rolled plate winding equipment can perform winding work efficiently and smoothly. In addition, by driving the second nip roller 23 to rotate through the fourth driving mechanism 25, additional power can be provided for the steel coil during the winding process, effectively improving the working efficiency of the flexible rolled plate winding equipment. It should be noted that the rotation direction of the second nip roller 23 can be the same as the rotation direction of the winding shaft 61, and the rotation direction of the second nip roller 23 can also be opposite to the rotation direction of the winding shaft 61. When there is no need to use the pressing roller mechanism 2 for pressing, the third driving mechanism 22 can drive the second rotating shaft 21 to rotate along the second direction, and the second rotating shaft 21 drives the second pressing arm 24 to rotate until the second pressing arm 24 drives the second pressing roller 23 and keeps it in the non-pressing position, thereby releasing the pressing effect of the second pressing roller 23 on the steel coil on the winding shaft 61, making it convenient for the staff to remove the steel coil.

[0045] Compared with the prior art, the press roller mechanism 2 provided in the embodiment of the utility model only needs to drive the second rotating shaft 21 to rotate along the first direction through the third driving mechanism 22 when pressing the material, and the second rotating shaft 21 drives the second press arm 24 to rotate or swing around the second rotating shaft 21 until the second press arm 24 drives and keeps the second press roller 23 in the pressing position, and the pressing force provided by the third driving mechanism 22 and the second press arm 24 is used to enable the second press roller 23 to stably press the steel coil on the winding shaft 61. At the same time, the second press roller 23 is driven to rotate by the fourth driving mechanism 25, so that rolling friction is generated between the second press roller 23 and the outer steel plate of the coil, effectively reducing the friction between the second press roller 23 and the outer steel plate of the coil, thereby ensuring that the flexible rolled plate winding equipment can efficiently and smoothly perform winding work.

[0046] Please refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the second pressing roller 23 includes a second pressing roller shaft 231 rotatably mounted on the second pressing arm 24 and a second pressing roller sleeve 232 sleeved on the second pressing roller shaft 231, the axial direction of the second pressing roller shaft 231 is parallel to the axial direction of the second rotating shaft 21, and the length direction of the second pressing arm 24 is perpendicular to the second rotating shaft 21. In addition, when the second pressing arm 24 drives and maintains the second pressing roller 23 at the pressing position, the second pressing arm 24 is arranged horizontally, and under the driving force of the third driving mechanism 22 plus the gravity of the second pressing arm 24, the second pressing roller 23 can stably press the steel coil on the winding shaft 61.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the fourth driving mechanism 25 includes a second motor 251 arranged on the second pressing arm 24, and the output shaft of the second motor 251 is connected to the second pressing roller shaft 231. The second pressing roller shaft 231 is driven to rotate by the second motor 251, and the second pressing roller shaft 231 drives the second pressing roller sleeve 232 to rotate, so that rolling friction is generated between the second pressing roller 23 and the outer steel plate of the coiled steel, effectively reducing the friction between the second pressing roller 23 and the outer steel plate of the coiled steel, thereby ensuring that the flexible rolled plate winding equipment can perform winding work efficiently and smoothly.

[0048] Please refer to Figure 2 , Figure 3 and Figure 5In some embodiments, the fourth driving mechanism 25 further includes a driving gear 252 mounted on the output shaft of the second motor 251, a driven gear 253 mounted on the second roller shaft 231, and a chain 254 for connecting the driving gear 252 and the driven gear 253. The second motor 251 drives the driving gear 252 to rotate, and the driving gear 252 drives the driven gear 253 to rotate under the transmission action of the chain 254. The driven gear 253 then drives the second roller shaft 231 to rotate, which can buffer the elastic force of the steel plate on the second roller sleeve 232. This is conducive to ensuring that the flexible rolled plate winding device can efficiently and smoothly perform winding work. In some embodiments, in order to further improve the stability and reliability of the power, the second motor 251 is a bidirectional hydraulic motor.

[0049] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the press roller mechanism 2 further includes a second swing arm 26, a first end of the second swing arm 26 is connected to the second rotating shaft 21, and a second end of the second swing arm 26 is connected to a power output end of the third driving mechanism 22. In this embodiment, since the first end of the second swing arm 26 is connected to the second rotating shaft 21, and the second end of the second swing arm 26 is connected to the power output end of the third driving mechanism 22, when the third driving mechanism 22 drives the second swing arm 26 to swing around the second rotating shaft 21, a lever movement effect can be formed, which can enhance the force of the second rotating shaft 21 driving the second press arm 24 to rotate, and is conducive to increasing the pressing force transmitted by the second press arm 24 to the second press roller 23, which is conducive to the second press roller 23 to stably press or press the outer steel plate of the steel coil.

[0050] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the third driving mechanism 22 is a second hydraulic cylinder, which can further increase the force of the second pressing roller 23 on the outer steel plate of the steel coil, which is helpful to prevent the outer layer of the steel coil from shaking and causing the risk of loose materials. Specifically, the cylinder body of the second hydraulic cylinder is used to be hinged with the machine table 3, and the piston rod of the second hydraulic cylinder is hinged with the second end of the second swing arm 26.

It can be understood that the fifth driving mechanism 4 can be but is not limited to a driving motor. When the fifth driving mechanism 4 drives the winding mechanism 6 to rotate, the winding mechanism 6 can continuously wind the flexible rolled plate so that the flexible rolled plate is wound to form a steel coil of a predetermined thickness. The cantilever support mechanism 5 is used to support the suspended end of the winding mechanism 6, and the cantilever support mechanism 5 is detachably connected to the suspended end of the winding mechanism 6.
