Thus, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, not all of which refer to the same embodiment. Furthermore, in one or more embodiments, the specialized features, structures, or characteristics may be combined in any suitable manner.

[0043] Please also read Figures 5 to 8, the press mechanism 5 provided in the embodiment of the utility model is now described. The press mechanism 5 provided in the embodiment of the utility model includes a rotating shaft 51, a first driving mechanism 52, a press roller 53, a press arm 54 and a second driving mechanism 55. The rotating shaft 51 is rotatably mounted on the machine 1 through a bearing and a bearing seat. The first driving mechanism 52 is installed on the machine 1 at a position corresponding to the rotating shaft 51. The power output end of the first driving mechanism 52 is connected to the rotating shaft 51, so that the first driving mechanism 52 can drive the rotating shaft 51 to rotate. The press roller 53 is used to press and hold the steel coil on the winding shaft 31. The first end of the press arm 54 is connected to the rotating shaft 51, and the second end of the press arm 54 is a suspended end. The press roller 53 is rotatably arranged at the suspended end of the press arm 54. The press arm 54 can drive the press roller 53 to swing and switch between the press position and the non-press position. The second driving mechanism 55 is arranged on the pressing arm 54 at a position corresponding to the pressing roller 53, and the second driving mechanism 55 is connected to the pressing roller 53, and the pressing roller 53 can be driven to rotate by the second driving mechanism 55. When the pressing mechanism 5 is used for pressing, the first driving mechanism 52 can drive the rotating shaft 51 to rotate along the first direction, and the rotating shaft 51 drives the pressing arm 54 to rotate until the pressing arm 54 drives the pressing roller 53 and keeps it at the pressing position, and under the pressing force provided by the first driving mechanism 52 and the pressing arm 54, the pressing roller 53 can stably press and hold the steel coil on the winding shaft 31. When the pressing roller 53 presses the steel coil on the winding shaft 31 and applies too much pressure to the outer steel plate of the steel coil, the pressing roller 53 is driven to rotate by the second driving mechanism 55, so that rolling friction is generated between the pressing roller 53 and the outer steel plate of the steel coil. Compared with the sliding friction generated between the pressing roller 53 and the outer steel plate of the steel coil, the friction between the pressing roller 53 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 pressing roller 53 to rotate by the second driving mechanism 55, 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 pressing roller 53 can be the same as the rotation direction of the winding shaft 31, and the rotation direction of the pressing roller 53 can also be opposite to the rotation direction of the winding shaft 31. When there is no need to use the pressing mechanism 5 for pressing, the first driving mechanism 52 can drive the rotating shaft 51 to rotate along the second direction, and the rotating shaft 51 drives the pressing arm 54 to rotate until the pressing arm 54 drives the pressing roller 53 and keeps it in the non-pressing position, thereby releasing the pressing effect of the pressing roller 53 on the steel coil on the winding shaft 31, making it convenient for the staff to remove the steel coil.

[0044] Compared with the prior art, the material pressing mechanism 5 provided in the embodiment of the utility model only needs to drive the rotating shaft 51 to rotate along the first direction through the first driving mechanism 52 when using the material pressing mechanism 5, and the rotating shaft 51 drives the material pressing arm 54 to rotate or swing around the rotating shaft 51 until the material pressing arm 54 drives and keeps the material pressing roller 53 in the material pressing position, and the pressing force provided by the first driving mechanism 52 and the material pressing arm 54 is used to enable the material pressing roller 53 to stably press the steel coil on the winding shaft 31. At the same time, the material pressing roller 53 is driven to rotate by the second driving mechanism 55, so that rolling friction is generated between the material pressing roller 53 and the outer steel plate of the steel coil, effectively reducing the friction between the material pressing roller 53 and the outer steel plate of the steel coil, thereby ensuring that the flexible rolled plate winding equipment can efficiently and smoothly perform winding work.

[0045] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments, the pressing roller 53 includes a pressing roller shaft 531 rotatably mounted on the pressing arm 54 and a pressing roller sleeve 532 sleeved on the pressing roller shaft 531. The axial direction of the pressing roller shaft 531 is parallel to the axial direction of the rotating shaft 51, and the length direction of the pressing arm 54 is perpendicular to the rotating shaft 51. In addition, when the pressing arm 54 drives and maintains the pressing roller 53 at the pressing position, the pressing arm 54 is arranged horizontally. Under the driving force of the first driving mechanism 52 and the gravity of the pressing arm 54, the pressing roller 53 can stably press and hold the steel coil on the winding shaft 31.

[0046] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments, the second driving mechanism 55 includes a motor 551 arranged on the pressing arm 54, and the output shaft of the motor 551 is connected to the pressing roller shaft 531. The motor 551 drives the pressing roller shaft 531 to rotate, and the pressing roller shaft 531 drives the pressing roller sleeve 532 to rotate, so that rolling friction is generated between the pressing roller 53 and the outer steel plate of the coiled steel, effectively reducing the friction between the pressing roller 53 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.

[0047] Please refer to Figure 5 , Figure 7 and Figure 8In some embodiments, the second driving mechanism 55 further includes a driving gear 552 mounted on the output shaft of the motor 551, a driven gear 553 mounted on the pressure roller shaft 531, and a chain 554 for connecting the driving gear 552 and the driven gear 553. The driving gear 552 is driven to rotate by the motor 551, and the driving gear 552 drives the driven gear 553 to rotate under the transmission action of the chain 554. The driven gear 553 then drives the pressure roller shaft 531 to rotate, which can buffer the impact force of the elastic force of the steel plate on the pressure roller sleeve 532, thereby 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 motor 551 is a bidirectional hydraulic motor.

[0048] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments, the pressing mechanism 5 further includes a swing arm 56, a first end of the swing arm 56 is connected to the rotating shaft 51, and a second end of the swing arm 56 is connected to the power output end of the first driving mechanism 52. In this embodiment, since the first end of the swing arm 56 is connected to the rotating shaft 51, and the second end of the swing arm 56 is connected to the power output end of the first driving mechanism 52, when the first driving mechanism 52 drives the swing arm 56 to swing around the rotating shaft 51, a lever movement effect can be formed, which can enhance the force of the rotating shaft 51 to drive the pressing arm 54 to rotate, and is conducive to increasing the pressing force transmitted by the pressing arm 54 to the pressing roller 53, which is conducive to the pressing roller 53 to stably press or press the outer steel plate of the steel coil.

[0049] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments, the first driving mechanism 52 is a second hydraulic cylinder, which can further increase the force of the pressing roller 53 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 platform 1, and the piston rod of the first hydraulic cylinder is hinged with the second end of the swing arm 56.

[0050] The embodiment of the utility model also provides a flexible rolled plate winding device, which includes the pressing mechanism 5 provided in any of the above embodiments. Since the flexible rolled plate winding device has all the technical features of the pressing mechanism 5 provided in any of the above embodiments, it has the same technical effects as the above pressing mechanism 5.

[0051] Please also read Figures 1 to 4, the flexible rolled plate winding device for facilitating the removal of steel coils provided in the embodiment of the utility model is now described. The flexible rolled plate winding device for facilitating the removal of steel coils provided in the embodiment of the utility model comprises a machine 1, a third driving mechanism 2, a winding mechanism 3 and a cantilever support mechanism 4. The first end of the winding mechanism 3 is rotatably arranged on the machine 1 through a bearing, and the second end of the winding mechanism 3 is a suspended end. The third driving mechanism 2 is arranged at a position on the machine 1 corresponding to the first end of the winding mechanism 3, and the power output shaft of the third driving mechanism 2 is connected to the first end of the winding mechanism 3 through a reducer and / or a transmission mechanism. It can be understood that the third driving mechanism 2 can be but is not limited to a driving motor. When the third driving mechanism 2 drives the winding mechanism 3 to rotate, the winding mechanism 3 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 4 is used to support the suspended end of the winding mechanism 3, and the cantilever support mechanism 4 is detachably connected to the suspended end of the winding mechanism 3. Please refer to further Figure 3 and Figure 4 The cantilever support mechanism 4 includes a support frame 41, a cantilever 43 rotatably arranged on the support frame 41 through a first pivot 42, and a fourth drive mechanism 44 driving the cantilever 43 to rotate. When the fourth drive mechanism 44 drives the cantilever 43 to rotate to the first position, the cantilever 43 is close to the winding mechanism 3, and the cantilever 43 can support the suspended end of the winding mechanism 3. At this time, the flexible rolled plate can be continuously wound by the winding mechanism 3. As the weight of the steel coil on the winding mechanism 3 continues to increase, the cantilever support mechanism 4 can balance the force at both ends of the winding mechanism 3, so that the force at both ends of the winding mechanism 3 is more uniform. When it is necessary to remove the steel coil from the winding mechanism 3, it is only necessary to drive the cantilever 43 to rotate to the second position through the fourth drive mechanism 44, so that the cantilever 43 is away from the winding mechanism 3, leaving enough avoidance space for the steel coil to move along the axial direction of the winding mechanism 3, so that the staff can quickly and efficiently remove the steel coil from the winding mechanism 3, which can shorten the time that the winding mechanism 3 needs to stop working, thereby effectively improving work efficiency.

[0052] The flexible rolled plate winding device that is convenient for removing the steel coil provided by the embodiment of the utility model, when it is necessary to open the winding mechanism 3 to wind the flexible rolled plate, it is only necessary to drive the cantilever 43 to rotate to the first position through the fourth driving mechanism 44, so that the cantilever 43 is located below the suspended end of the winding mechanism 3 and stably supports the suspended end of the winding mechanism 3. When the weight of the steel coil on the winding mechanism 3 continues to increase, the force on both ends of the winding mechanism 3 can be balanced to make the force on both ends of the winding mechanism 3 more uniform, so as to avoid the first end of the winding mechanism 3 being subjected to excessive pressure and affecting the stability and service life of the winding mechanism 3. When it is necessary to remove the steel coil that has been rolled from the winding mechanism 3, it is only necessary to drive the cantilever 43 to rotate to the second position through the fourth driving mechanism 44, so that the support for the suspended end of the winding mechanism 3 is released and away from the winding mechanism 3, which can facilitate the staff to quickly and efficiently remove the steel coil from the winding mechanism 3, thereby effectively improving work efficiency.

[0053] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the first end of the cantilever 43 is rotatably connected to the support frame 41 through the first pivot 42, and the second end of the cantilever 43 is used to support the suspended end of the winding mechanism 3, so that the fourth driving mechanism 44 can stably drive the cantilever 43 to rotate to the first position or the second position, so that the cantilever 43 can be quickly lifted or lowered as needed, which is convenient for the winding mechanism 3 to wind up the flexible rolled plate or facilitate the staff to quickly and efficiently remove the steel coil from the winding mechanism 3.

[0054] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, a positioning member 6 is provided on the second end of the cantilever 43, and a positioning groove 7 is provided on the positioning member 6 for accommodating and positioning the suspended end of the winding mechanism 3. When the suspended end of the winding mechanism 3 is supported in the positioning groove 7 of the positioning member 6, on the one hand, the suspended end of the winding mechanism 3 can be prevented from being displaced due to the vibration generated during the winding process, and even causing the suspended end of the winding mechanism 3 to fall off the cantilever 43; on the other hand, the contact area between the suspended end of the winding mechanism 3 and the cantilever 43 can be increased, which can improve the supporting effect of the cantilever 43 on the suspended end of the winding mechanism 3, so that the force on both ends of the winding mechanism 3 is more uniform.

[0055] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the fourth driving mechanism 44 includes a first connecting rod 441, a second connecting rod 442, a second pivot 443, a third pivot 444, a fourth pivot 445, a fifth pivot 446 and a second hydraulic cylinder 447, the first end of the first connecting rod 441 is rotationally connected to the cantilever 43 through the second pivot 443, the second end of the first connecting rod 441 is rotationally connected to the first end of the second connecting rod 442 through the third pivot 444, the second end of the second connecting rod 442 is rotationally connected to the support frame 41 through the fourth pivot 445, the cylinder body of the second hydraulic cylinder 447 is rotationally connected to the support frame 41 through the fifth pivot 446, and the piston rod of the second hydraulic cylinder 447 is connected to the third pivot 444. In this embodiment, when it is necessary to open the winding mechanism 3 to wind the flexible rolled plate, it is only necessary to drive the first connecting rod 441 and the second connecting rod 442 to rotate simultaneously around the third pivot 444 in the first direction through the second hydraulic cylinder 447, so as to lift the cantilever 43 until the cantilever 43 rotates to the first position, so that the cantilever 43 is located below the suspended end of the winding mechanism 3 and stably supports the suspended end of the winding mechanism 3. When the weight of the steel coil on the winding mechanism 3 continues to increase, the force at both ends of the winding mechanism 3 can be balanced to make the force at both ends of the winding mechanism 3 more uniform, thereby avoiding excessive pressure on the first end of the winding mechanism 3 and affecting the stability and service life of the winding mechanism 3. When it is necessary to remove the coiled steel coil from the winding mechanism 3, it is only necessary to drive the first connecting rod 441 and the second connecting rod 442 to rotate around the third pivot 444 toward the first direction at the same time through the second hydraulic cylinder 447, so as to realize the lowering of the cantilever 43, until the cantilever 43 rotates to the second position, so as to release the support for the suspended end of the winding mechanism 3 and move away from the winding mechanism 3, so as to facilitate the staff to quickly and efficiently remove the steel coil from the winding mechanism 3, thereby effectively improving the work efficiency. In addition, the first connecting rod 441, the part of the cantilever 43 located between the first pivot 42 and the second pivot 443, and the second hydraulic cylinder 447 constitute a stable triangular support structure, so that the cantilever 43 can stably support the suspended end of the winding mechanism 3. When the weight of the steel coil on the winding mechanism 3 continues to increase, the force at both ends of the winding mechanism 3 can be balanced to make the force at both ends of the winding mechanism 3 more uniform, so as to avoid the first end of the winding mechanism 3 from being subjected to excessive pressure and affecting the stability and service life of the winding mechanism 3.

[0056] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the fourth driving mechanism 44 further includes a rotating sleeve 448 rotatably mounted on the third pivot 444, and the piston rod of the second hydraulic cylinder 447 is connected to the rotating sleeve 448, which can not only improve the stability of the piston rod of the second hydraulic cylinder 447 driving the first connecting rod 441 and the second connecting rod 442 to rotate around the third pivot 444 at the same time, but also prevent the piston rod of the second hydraulic cylinder 447 from bending or even breaking in the process of the cantilever 43 supporting the suspended end of the winding mechanism 3. In addition, due to the provision of the rotating sleeve 448, the contact surface support replaces the contact point support, which can effectively increase the contact area between the piston rod of the second hydraulic cylinder 447 and the third pivot 444, and can disperse the force acting on the third pivot 444, so that the cantilever support mechanism 4 can support the suspended end of the winding mechanism 3 more stably.

[0057] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the fourth driving mechanism 44 also includes a first hinged seat 449 rotatably connected to the third pivot 444, and the first hinged seat 449 is connected to the second end of the first connecting rod 441, thereby improving the stability of the first connecting rod 441 rotating around the third pivot 444, and enabling the cantilever support mechanism 4 to support the suspended end of the winding mechanism 3 more stably.

[0058] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the fourth driving mechanism 44 also includes a second articulated seat 450 fixedly connected to the support frame 41, and the cylinder body of the second hydraulic cylinder 447 is rotatably connected to the second articulated seat 450 through a fifth pivot 446, which can make the cantilever support mechanism 4 support the suspended end of the winding mechanism 3 more stably.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the winding mechanism 3 includes a winding shaft 31, a supporting column 32, and an expansion and contraction roller 33 sleeved on the winding shaft 31. The first end of the winding shaft 31 is rotatably mounted on the machine platform 1, and the first end of the winding shaft 31 is rotatably connected to the supporting column 32. The supporting column 32 constitutes the suspended end of the winding mechanism 3. By sleeved the expansion and contraction roller 33 on the winding shaft 31, the tightness of the steel coil wound on the winding shaft 31 can be ensured.

[0060] Please refer to Figure 1 , Figure 2 and Figure 3 In some of the embodiments, a shock-absorbing sleeve is provided on the supporting column 32, which can better prevent the suspended end of the winding mechanism 3 from being displaced due to the vibration generated during the winding process.
