The rotary box has a hollow structure, and two centrally symmetrical first through holes are provided on one side end face of the rotary box. One end of each of the two winding drums is disposed inside the rotary box, and the other end of each of the two winding drums passes through the two first through holes respectively. Two drive motors are connected inside the rotary box and are used to drive the two winding drums to rotate around the axial direction of the winding drums. The drive mechanism is used to drive the rotary box to rotate around the axial direction of the rotary box.

[0005] Optionally, the drive motor includes a housing, a stator, a rotor coil, and a rotor sleeve shaft connected sequentially from the outside to the inside. The two ends of the housing are respectively connected to the two end faces of the turntable box. The stator is used to drive the rotor coil and the rotor sleeve shaft to rotate. A first connecting hole is provided on the end face of the housing facing the first through hole. The rotor sleeve shaft is a hollow tubular structure. The drum passes through the first connecting hole and the rotor sleeve shaft and is connected to the rotor sleeve shaft.

[0006] Optionally, one end of the rotor sleeve shaft passes through the first connecting hole and the first through hole in sequence, a first connecting ring is provided on the circumferential surface of the end of the rotor sleeve shaft that passes through the first through hole, and a second connecting ring is provided on the circumferential surface of the drum, and the first connecting ring and the second connecting ring are connected by threads.

[0007] Optionally, the direct-drive rotary winding machine also includes an expansion cylinder. The rotary box is also provided with a second through hole. The second through hole and the first through hole are located on the end faces of both sides of the rotary box and are coaxially arranged. The expansion cylinder is driven to the part of the drum that passes through the second through hole. The expansion cylinder is used to tighten or expand the drum.

[0008] Optionally, the direct-drive rotary winding machine also includes a quick-release sleeve. The ends of the expansion cylinder and the drum opposite each other are provided with boss structures of the same size. The two boss structures abut against each other. The quick-release sleeve is a semi-circular structure with a connecting groove. The two boss structures are embedded in the connecting groove formed by the two quick-release sleeves. The two quick-release sleeves are connected by threads.

[0009] Optionally, the direct-drive rotary winding machine also includes idler rollers. Two idler rollers are spaced apart on the mounting platform below the rotary box. The two idler rollers extend along the axial direction of the rotary box and are arranged in parallel. The idler rollers are in rolling contact with the rotary box.

[0010] Optionally, a locking block is provided at the edge of one side end face of the turntable box, and two locking plates are provided on the mounting platform below the turntable box. The two locking plates are used to slide relative to the mounting platform to abut against two end faces of the locking block that are spaced apart along the circumference of the turntable box, so as to clamp or release the locking block.

[0011] Optionally, the driving mechanism includes a bracket, a rotating gear, and a rotating motor. A rotating shaft is provided at the center of the turntable box.

[0014] Compared with the prior art, the beneficial effects of the direct-drive rotary winder of the present invention are:

[0015] This invention features a turntable box with two centrally symmetrical first through holes on one side. This allows two drums to be inserted into the turntable box along these holes. Part of the drum is located outside the turntable box, while a portion is inside. The turntable box also houses two drive motors. These motors drive the portions of the drums inside the turntable box to rotate around their respective axes (Y-axis), thus rotating the portions outside the turntable box. The steel strip can then be wound around the portions of the drums outside the turntable box. As the drums rotate, the steel strip is wound around them. The drive mechanism is then rotatably connected to the turntable box. The drive mechanism can drive the turntable box to rotate around its axis, that is, rotate around the Y-axis. The turntable box can drive two drums to rotate around its axis to circulate and wind up the steel strip, thereby improving the winding efficiency of the steel strip. At the same time, by directly setting the drive motor inside the turntable box, instead of setting the complex transmission structure of the drive shaft, reducer, and gear distribution box on the outside of the turntable box, the drive motor has a simple structure, occupies less space, and is less prone to problems during the transmission process, reducing the probability of problems with the winding machine and improving the working efficiency of the winding machine.

[0023] Furthermore, although specific embodiments have been described herein, it should be understood that these embodiments are merely examples of the principles and applications of the invention. Therefore, it should be understood that many modifications can be made to the exemplary embodiments, and other arrangements can be designed without departing from the spirit and scope of the invention as defined by the appended claims. It should be understood that different dependent claims and features herein can be combined in ways not used as described in the original claims. It is also understood that features described in conjunction with individual embodiments can be used in other embodiments.

[0024] To solve the above problems, as shown in Figures 1 and 2, the present invention provides a direct-drive rotary winding machine, including a drive mechanism, a rotary box 1, winding drums 2, and a drive motor 3. The rotary box 1 has a hollow structure, and two centrally symmetrical first through holes are opened on one end face of the rotary box 1. One end of each of the two winding drums 2 is disposed inside the rotary box 1, and the other end of each of the two winding drums 2 passes through the rotary box 1 through the two first through holes respectively. The two drive motors 3 are connected inside the rotary box 1 and are used to drive the two winding drums 2 to rotate around the axial direction of the winding drums 2 respectively. The drive mechanism is used to drive the rotary box 1 to rotate around the axial direction of the rotary box 1.

[0025] In this embodiment, a turntable box 1 is provided, and two centrally symmetrical first through holes are opened on one side end face of the turntable box 1 to facilitate the insertion of two drums 2 into the turntable box 1 along the two first through holes. Part of the drums 2 is located outside the turntable box 1, and part is located inside the turntable box 1. The turntable box 1 is also provided with two drive motors 3. The two drive motors 3 drive the portions of the two drums 2 located inside the turntable box 1 to rotate around the axis of the drums 2, that is, around the Y-axis, thereby driving the portions of the drums 2 located outside the turntable box 1 to rotate. The steel strip can be wound around the portions of the drums 2 located outside the turntable box 1. When the drums 2 rotate, the steel strip can be wound around them. A drive mechanism is then installed on the drum 2 and rotatably connected to the turntable box 1. The drive mechanism can drive the turntable box 1 to rotate around its axis, that is, rotate around the Y-axis. The turntable box 1 can drive the two drums 2 to rotate around its axis to circulate and wind up the steel strip, thereby improving the winding efficiency of the steel strip. At the same time, by directly setting the drive motor 3 inside the turntable box 1, instead of setting the complex transmission structure of the drive shaft, reducer, and gear distribution box on the outside of the turntable box 1, the drive motor 3 has a simple structure, occupies little space, and is less prone to problems during the transmission process, reducing the probability of problems with the winding machine and improving the working efficiency of the winding machine.

[0026] Specifically, the two drums 2 are divided into a first drum and a second drum. During operation, the first drum rotates at the first station to wind up the steel strip. The drive mechanism simultaneously drives the turntable box 1 to rotate until the first drum rotates 180 degrees to the second station. After the steel strip is wound to the specified size, it is cut. At this time, the second drum is located at the first station and begins to rotate to wind up the steel strip and remove the steel strip from the first drum, thus completing the position exchange between the first drum and the second drum. The first station is the steel strip winding station, and the second station is the station for removing the rolled-up steel strip. This process is repeated so that the two drums 2 continuously and cyclically wind up the steel strip, improving the working efficiency of the winding machine.

[0027] Optionally, as shown in Figure 2, the drive motor 3 includes a housing 31, a stator 32, a rotor coil 33, and a rotor sleeve 34 connected sequentially from the outside to the inside. The two ends of the housing 31 are respectively connected to the two end faces of the turntable box 1. The stator 32 is used to drive the rotor coil 33 and the rotor sleeve 34 to rotate. A first connecting hole is provided on the end face of the housing 31 facing the first through hole. The rotor sleeve 34 is a hollow tubular structure. The drum 2 passes through the first connecting hole and the rotor sleeve 34 and is connected to the rotor sleeve 34.

[0028] In this embodiment, a housing 31 is provided, with its two end faces along the Y-axis connected to the end faces of the turntable box 1 along the Y-axis, facilitating the fixed connection of the drive motor 3 inside the turntable box 1. Inside the housing 31, from the outside in, are a stator 32, a rotor coil 33, and a rotor sleeve 34. The stator 32 drives the rotor coil 33 and the rotor sleeve 34 to rotate. The rotor sleeve 34 is a hollow tubular structure. A first connecting hole is provided at the center of the end face of the housing 31 facing the positive Y-direction. The drum 2 is inserted into the rotor sleeve 34 through the first through hole and the first connecting hole. It is connected to the rotor sleeve shaft 34. When the drive motor 3 is working, the rotor sleeve shaft 34 drives the drum 2 to rotate. In this invention, the drive motor 3 is set as an internal rotor motor, and a hollow rotor sleeve shaft 34 is set in the center of the rotor to connect the drum 2 inserted into the turntable box 1. This setting makes it easy to directly connect the drive motor 3 inside the turntable box 1, replacing the existing transmission shaft, reducer, and gear distribution box arranged outside the turntable box 1, saving space, simplifying the structure of the drive device used to drive the drum 2 to rotate, and making the drive process of the drive motor 3 less prone to problems, thus improving the working efficiency of the winding machine.

[0029] Optionally, as shown in FIG2, one end of the rotor sleeve shaft 34 passes through the first connecting hole and the first through hole in sequence. A first connecting ring 35 is provided on the circumferential surface of the end of the rotor sleeve shaft 34 that passes through the first through hole, and a second connecting ring 21 is provided on the circumferential surface of the drum 2. The first connecting ring 35 and the second connecting ring 21 are connected by threads.

[0030] In this embodiment, the rotor sleeve shaft 34 is configured to pass through the first connecting hole and the first through hole to exit the turntable box 1. A first connecting ring 35 is provided at the end of the rotor sleeve shaft 34 facing the positive Y-axis. The first connecting ring 35 extends in the plane of the X-axis and Z-axis and is sleeved on the peripheral surface of the rotor sleeve shaft 34, integrally formed with the rotor sleeve shaft 34. A second connecting ring 21 is provided on the peripheral surface of the drum 2. The second connecting ring 21 also extends in the plane of the X-axis and Z-axis. When the drum 2 is inserted into the rotor sleeve shaft 34, the second connecting ring 21 abuts against the first connecting ring 35 to position the drum 2 in the Y-axis direction. Then, bolts are used to connect the first connecting ring 35 and the second connecting ring 21 together, so that the rotor sleeve shaft 34 can drive the drum 2 to rotate together.

[0031] Optionally, as shown in Figures 2 and 3, the direct-drive rotary winding machine further includes an expansion cylinder 4. The rotary box 1 is also provided with a second through hole. The second through hole and the first through hole are located on the end faces of the two sides of the rotary box 1 and are coaxially arranged. The expansion cylinder 4 is drivenly connected to the part of the drum 2 that passes through the second through hole. The expansion cylinder 4 is used to tighten or expand the drum 2.

[0032] In this embodiment, a second through hole is opened on the end face of the turntable box 1 facing the negative Y-axis. The axis of the second through hole and the axis of the first through hole are the same straight line. The end of the drum 2 facing the negative Y-axis passes through the second through hole. An expansion cylinder 4 is provided on the side of the turntable box 1 facing the negative Y-axis. The expansion cylinder 4 is drivenly connected to the drum 2 to control the tightening or expansion of the drum 2.

[0033] Specifically, the specific structure of the expansion and contraction cylinder 4 can be referred to in utility model patent CN207293829U. The drive motor 3 housing 31 has a connecting hole on one end facing the negative Y-axis direction for the drum 2 to pass through.

[0034] Optionally, the direct-drive rotary winding machine also includes a quick-release sleeve 52. The ends of the expansion cylinder 4 and the drum 2 opposite each other are provided with boss structures 51 of the same size. The two boss structures 51 abut against each other. The quick-release sleeve 52 is a semi-circular structure. A connecting groove is provided on the quick-release sleeve 52. The two boss structures 51 are embedded in the connecting groove formed by the two quick-release sleeves 52. The two quick-release sleeves 52 are connected by threads.

[0035] In this embodiment, boss structures 51 are provided at the ends of the expansion cylinder 4 facing the positive Y-axis and the drum 2 facing the negative Y-axis, i.e., at the piston rod of the expansion cylinder 4 and the pull rod of the drum 2. The diameter of the boss structure 51 is larger than the diameter of the piston rod and larger than the diameter of the pull rod of the drum 2. When the expansion cylinder 4 and the drum 2 are connected, the two boss structures 51 abut against each other. Two semi-circular quick-release sleeves 52 are then provided. Connecting grooves are provided on the end faces of the quick-release sleeves 52. The structure of the connecting grooves is similar to that of the bosses. Corresponding to structure 51, two quick-release sleeves 52 can be fastened to the sides of two abutting boss structures 51 in the plane of X-axis and Z-axis. The two abutting boss structures 51 are embedded in two enclosed connecting grooves. The two quick-release sleeves 52 are connected together by bolts, which makes it easy to fix the two boss structures 51 together, thereby connecting the expansion cylinder 4 and the drum 2 together. When replacing the drum 2, it is only necessary to remove the two quick-release sleeves 52 and then remove the first connecting ring 35 and the second connecting ring 21.

[0036] Specifically, the quick-release sleeve 52 has a connecting hole on the end face facing the positive Y-axis for the pull rod of the drum 2 to pass through, and a connecting hole on the end face facing the negative Y-axis for the piston rod of the expansion cylinder 4 to pass through.

[0037] Optionally, as shown in Figure 1, the direct-drive rotary winding machine further includes idler rollers 6. Two idler rollers 6 are spaced apart on the mounting platform below the rotary box 1. The two idler rollers 6 extend along the axial direction of the rotary box 1 and are arranged in parallel. The idler rollers 6 are in rolling contact with the rotary box 1.

[0038] In this embodiment, the two idler rollers 6 are symmetrically arranged with respect to the central axis of the turntable box 1. On the mounting platform, idler rollers 6 are provided on the side of the turntable box 1 facing the negative Z-axis and the negative X-axis, and on the side facing the negative Z-axis and the positive X-axis. The idler rollers 6 extend along the Y-axis and can rotate around the central axis of the idler rollers 6. The peripheral surface of the idler rollers 6 rolls in contact with the peripheral surface of the turntable box 1. The two idler rollers 6 can provide support force to the turntable box 1 in the positive and negative X-axis directions respectively, in the direction of the positive Z-axis, so as to prevent the turntable box 1 from tilting under the superposition of external forces such as the weight of the turntable box 1 and the weight of the steel belt. The idler rollers 6 can rotate with the turntable box 1 and will not affect the normal operation of the turntable box 1.

[0039] Optionally, as shown in Figure 1, a locking block 71 is provided at the edge of one side end face of the turntable box 1, and two locking plates 72 are provided on the mounting platform below the turntable box 1. The two locking plates 72 are used to slide relative to the mounting platform to abut against two end faces of the locking block 71 that are spaced apart along the circumference of the turntable box 1, so as to clamp or release the locking block 71.

[0040] In this embodiment, a locking block 71 is provided at the edge of the end face of the turntable box 1, and a locking plate 72 is provided below the turntable box 1 on the mounting platform. The two locking plates 72 are arranged along the X-axis direction and can slide along the X-axis direction. When the turntable box 1 does not need to rotate, the turntable box 1 is first rotated so that the locking block 71 faces the negative Z-axis direction. Then, the two locking plates 72 are slid to the two ends of the locking block 71 facing the X-axis direction to clamp the locking block 71 and limit the locking block 71 to prevent the turntable box 1 from continuing to rotate. When the turntable box 1 needs to rotate, the two locking plates 72 slide away from the locking block 71 so as not to affect the normal rotation of the turntable box 1.

[0041] Specifically, the installation platform is provided with a telescopic cylinder 73, which is located on the end of the locking plate 72 away from the locking block 71 and can extend and retract along the X-axis. The telescopic cylinder 73 is driven to connect with the locking plate 72 to drive the locking plate 72 to slide in the X-axis direction.

[0042] Optionally, the driving mechanism includes a bracket 81, a rotating gear 82, and a rotating motor 83. A rotating shaft 11 is provided at the center of the turntable box 1. The rotating shaft 11 and the drum 2 extend out of the turntable box 1 to both sides of the turntable box 1. A fixing hole is provided on the bracket 81, and the rotating shaft 11 passes through the fixing hole. The rotating gear 82 is sleeved and fixed on the rotating shaft 11. The rotating motor 83 is connected to the bracket 81, and the rotating motor 83 is drivenly connected to the rotating gear 82.

[0043] In this embodiment, a bracket 81 is set on the mounting platform, and a fixing hole is opened on the bracket 81 so that the rotating shaft 11, which is set on the central axis of the turntable box 1 and extends in the negative direction of the Y-axis, can pass through the fixing hole to fix the turntable box 1 on the mounting platform. Then, a rotating gear 82 is sleeved on the circumferential surface of the rotating shaft 11. A rotating motor 83 is set on the bracket 81. The rotating motor 83 is driven and connected to the rotating gear 82. When the rotating motor 83 works, it drives the rotating gear 82 to rotate, thereby driving the rotating shaft 11 and the turntable box 1 to rotate, so as to realize the rotation of the turntable box 1.

[0044] Specifically, the rotating gear 82 is keyed to the rotating shaft 11, which can be a hollow structure. The end of the rotating shaft 11 facing the negative Y-axis is provided with a second rotary joint, which is used to supply power to the drive motor 3 and to provide hydraulic oil and lubricating oil to the drum 2.

[0045] Optionally, as shown in Figure 2, the end of the expansion cylinder 4 away from the drum 2 is provided with a first rotary joint 41, which is used to deliver hydraulic oil.

[0046] In this embodiment, a first rotary joint 41 is provided at the end of the expansion cylinder 4 away from the drum 2. The first rotary joint 41 provides hydraulic oil for the expansion cylinder 4 to work, so that the expansion cylinder 4 can drive the drum 2 to tighten or expand.

[0047] Optionally, the turntable box 1 is also equipped with a cooling fan, which is used to cool the drive motor 3.

[0048] In this embodiment, by installing a cooling fan inside the turntable box 1, the cooling fan blows air onto the drive motor 3 to cool the drive motor 3, extend the working life of the drive motor 3, and ensure that the working temperature of the drive motor 3 meets the requirements. By installing the cooling fan inside the turntable box 1, the space inside the turntable box 1 can be fully utilized, thereby improving the space utilization rate.

[0049] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
