[0024] Moreover, although the present invention is described with reference to specific embodiments, it should be understood that these embodiments are merely examples of the principles and applications of the present invention. It should therefore be understood that many modifications may be made to the exemplary embodiments and that other arrangements may be designed without departing from the spirit and scope of the present invention as defined by the appended claims. It should be understood that the features of the various dependent claims and herein may be combined in a manner not described in the original claims. It may also be understood that the features described in conjunction with the individual embodiments may be used in other embodiments.

[0025] To solve the above problems, Figure 1 and Figure 2 As shown, the present invention provides a motor-direct-driven turntable winder, comprising a driving mechanism, a turntable box 1, a reel 2 and a driving motor 3. The turntable box 1 is a hollow structure, and one side end face of the turntable box 1 is provided with two centrally symmetrical first through holes, one end of the two reels 2 are both arranged in the turntable box 1, and the other ends of the two reels 2 respectively pass through the turntable box 1 along the two first through holes, the two driving motors 3 are connected in the turntable box 1, and are respectively used to drive the two reels 2 to rotate around the axial direction of the reel 2, and the driving mechanism is used to drive the turntable box 1 to rotate around the axial direction of the turntable box 1.

[0026] In this embodiment, a turntable box 1 is provided, and two first through holes with central symmetry are opened on one side end surface of the turntable box 1, so that two reels 2 can be inserted into the turntable box 1 along the two first through holes. The reels 2 are partially located outside the turntable box 1 and partially located inside the turntable box 1. Two driving motors 3 are also provided inside the turntable box 1. The two driving motors 3 respectively drive the parts of the two reels 2 located inside the turntable box 1 to rotate around the axis of the reels 2, that is, around the Y axis, and drive the parts of the reels 2 located outside the turntable box 1 to rotate. The steel belt can be wound around the parts of the reels 2 located outside the turntable box 1. When the reels 2 rotate, the steel belt can be wound around the parts of the reels 2 located outside the turntable box 1. A driving mechanism is arranged on the reel 2 to be rotatably connected with the turntable box 1. The driving mechanism can drive the turntable box 1 to rotate around the axis of the turntable box 1, that is, to rotate around the Y-axis. The turntable box 1 can drive the two reels 2 to rotate around the axis of the turntable box 1 to cyclically wind the steel strip, thereby improving the winding efficiency of the steel strip. At the same time, by directly arranging the driving motor 3 inside the turntable box 1, instead of arranging a transmission shaft, a reducer, and a gear distribution box with a complex transmission structure on the outside of the turntable box 1, the driving motor 3 has a simple structure and occupies a small space. Problems are not prone to occur in the transmission process, which reduces the probability of problems with the coiler and improves the working efficiency of the coiler.

[0027] Specifically, the two reels 2 are divided into a first reel and a second reel. During operation, the first reel is located at the first station and rotates to wind up the steel strip. The driving mechanism simultaneously drives the turntable box 1 to rotate until the first reel rotates 180 degrees to the second station. After the steel strip is wound to a specified size, the steel strip is cut off. At this time, the second reel is located at the first station and starts to rotate to wind up the steel strip, and the steel strip on the first reel is taken down, completing the position exchange of the first reel and the second reel. The first station is the steel strip winding station, and the second station is the station for taking down the steel strip roll. Repeat this process so that the two reels 2 can continuously cycle and wind up the steel strip, thereby improving the working efficiency of the winder.

[0028] Alternatively, if Figure 2 As shown, the driving motor 3 includes a shell 31, a stator 32, a rotor coil 33 and a rotor sleeve 34 which are connected in sequence from the outside to the inside. The two ends of the shell 31 are respectively connected to the two end surfaces 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 opened on the end surface of the shell 31 facing the first through hole. The rotor sleeve 34 is a hollow tubular structure. The reel 2 passes through the first connecting hole and the rotor sleeve 34 and is connected to the rotor sleeve 34.

[0029] In this embodiment, by providing a shell 31, the end surfaces of the shell 31 on both sides along the Y-axis direction are respectively connected to the end surfaces of the turntable box 1 on both sides along the Y-axis direction, so as to facilitate the fixed connection of the drive motor 3 to the inside of the turntable box 1. The inside of the shell 31 is sequentially provided with a stator 32, a rotor coil 33 and a rotor sleeve shaft 34 from the outside to the inside. The stator 32 is used to drive the rotor coil 33 and the rotor sleeve shaft 34 to rotate. The rotor sleeve shaft 34 is a hollow tubular structure. The center of the end surface of the shell 31 facing the positive direction of the Y-axis is provided with a first connecting hole. The reel 2 is inserted into the rotor sleeve shaft 34 along the first through hole and the first connecting hole. And it is connected with the rotor sleeve 34. When the driving motor 3 is working, the rotor sleeve 34 drives the reel 2 to rotate. The present invention configures the driving motor 3 as an inner rotor motor, and arranges a hollow rotor sleeve 34 in the center of the rotor to connect the reel 2 inserted into the turntable box 1. This arrangement facilitates the direct connection of the driving motor 3 to the inside of 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 driving device for driving the reel 2 to rotate, and the driving process of the driving motor 3 is not prone to problems, thereby improving the working efficiency of the winder.

[0030] Alternatively, if Figure 2 As shown, one end of the rotor sleeve 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 34 passing through the first through hole, and a second connecting ring 21 is provided on the circumferential surface of the reel 2, and the first connecting ring 35 and the second connecting ring 21 are connected by threads.

[0031] In this embodiment, the end of the rotor sleeve 34 facing the positive direction of the Y-axis is arranged to pass through the first connecting hole and the first through hole to pass through the turntable box 1, and a first connecting ring 35 is arranged at the end of the rotor sleeve 34 facing the positive direction of the Y-axis, the first connecting ring 35 extends in the plane where the X-axis and Z-axis are located, and is sleeved on the circumferential surface of the rotor sleeve 34, and is arranged integrally with the rotor sleeve 34, and a second connecting ring 21 is arranged on the circumferential surface of the reel 2, and the second connecting ring 21 also extends in the plane where the X-axis and Z-axis are located. When the reel 2 is inserted into the rotor sleeve 34, the second connecting ring 21 abuts against the first connecting ring 35, and the reel 2 is positioned in the Y-axis direction, and then the first connecting ring 35 and the second connecting ring 21 are connected together with bolts, so that the rotor sleeve 34 can drive the reel 2 to rotate together.

[0032] Alternatively, if Figure 2 and Figure 3As shown, the motor-driven turntable winder also includes an expansion and contraction cylinder 4. A second through hole is also provided on the turntable box 1. The second through hole and the first through hole are respectively located on the end faces on both sides of the turntable box 1 and are coaxially arranged. The expansion and contraction cylinder 4 is drivingly connected to the part of the reel 2 that passes through the second through hole. The expansion and contraction cylinder 4 is used to tighten or expand the reel 2.

[0033] In this embodiment, a second through hole is opened on the end face of the turntable box 1 facing the negative direction of the Y-axis, the axis of the second through hole is in the same straight line as the axis of the first through hole, and the end of the reel 2 facing the negative direction of the Y-axis passes through the second through hole, and an expansion and contraction cylinder 4 is arranged on the side of the turntable box 1 facing the negative direction of the Y-axis, and the expansion and contraction cylinder 4 is connected to the reel 2 to control the tightening or expansion of the reel 2.

[0034] Specifically, the specific structure of the expansion and contraction cylinder 4 can refer to the utility model patent CN207293829U, and a connecting hole for the winding drum 2 to pass through is opened on one end of the driving motor 3 housing 31 facing the negative direction of the Y axis.

[0035] Optionally, the motor-driven turntable winder also includes a quick-release sleeve 52, and the ends of the expansion and contraction cylinder 4 opposite to the reel 2 are provided with boss structures 51 of the same size, and the two boss structures 51 are abutted. The quick-release sleeve 52 is a semicircular structure, and a connecting groove is opened 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, and the two quick-release sleeves 52 are connected by threads.

[0036] In this embodiment, a boss structure 51 is provided at one end of the expansion and contraction cylinder 4 facing the positive direction of the Y axis and at the end of the reel 2 facing the negative direction of the Y axis, that is, at the piston rod of the expansion and contraction cylinder 4 and the end of the pull rod of the reel 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 reel 2. When the expansion and contraction cylinder 4 and the reel 2 are connected, the two boss structures 51 abut against each other, and two semicircular quick-release sleeves 52 are provided. A connecting groove is provided on the end surface of the quick-release sleeve 52. The structure of the connecting groove and the boss structure are connected. Corresponding to the structure 51, the two quick-release sleeves 52 can be buckled on the sides of the two abutting boss structures 51 in the plane where the X-axis and Z-axis are located, and 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 is convenient for fixing the two boss structures 51 together, and then connecting the expansion and contraction cylinder 4 and the reel 2 together. When replacing the reel 2, it is only necessary to disassemble the two quick-release sleeves 52, and then disassemble the first connecting ring 35 and the second connecting ring 21.

[0037] Specifically, a connection hole for the pull rod of the reel 2 to pass through is opened on the end surface of the quick release sleeve 52 facing the positive direction of the Y axis, and a connection hole for the piston rod of the expansion and contraction cylinder 4 to pass through is opened on the end surface facing the negative direction of the Y axis.

[0038] Alternatively, if Figure 1 As shown, the motor-driven turntable winder also includes rollers 6. Two of the rollers 6 are spaced apart on the mounting platform below the turntable box 1. The two rollers 6 extend along the axial direction of the turntable box 1 and are arranged in parallel. The rollers 6 are in rolling contact with the turntable box 1.

[0039] In this embodiment, the two rollers 6 are symmetrically arranged with respect to the central axis plane of the turntable box 1. On the mounting platform, rollers 6 are arranged on the side of the turntable box 1 facing the negative direction of the Z axis and the negative direction of the X axis, and on the side facing the negative direction of the Z axis and the positive direction of the X axis. The rollers 6 extend along the Y axis direction and can rotate around the central axis of the rollers 6. The circumferential surface of the rollers 6 is in rolling contact with the circumferential surface of the turntable box 1. The two rollers 6 can provide support force to the turntable box 1 in the positive direction of the Z axis in the positive and negative directions of the X axis, respectively, to prevent the turntable box 1 from tilting when external forces such as the weight of the turntable box 1 and the weight of the steel belt are superimposed. The rollers 6 can rotate together with the turntable box 1 and will not affect the normal operation of the turntable box 1.

[0040] Alternatively, if Figure 1 As shown, a locking block 71 is provided at the edge of one end surface 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 respectively abut against two end surfaces of the locking block 71 spaced apart along the circumference of the turntable box 1 to clamp or release the locking block 71.

[0041] When the lock body 7 is in the unlocking state, the locking plate 77 is in the unlocking state, and the locking plate 78 is in the unlocking state, so that the locking plate 78 is locked and the unlocking state is realized.

[0042] Specifically, a telescopic cylinder 73 is provided on the mounting platform. The telescopic cylinder 73 is arranged on one end of the locking plate 72 away from the locking block 71 and can be extended and retracted along the X-axis direction. The telescopic cylinder 73 is drivingly connected to the locking plate 72 to drive the locking plate 72 to slide in the X-axis direction.

[0043] 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.

[0044] In this embodiment, a bracket 81 is arranged on the mounting platform, and a fixing hole is opened on the bracket 81, so that the rotating shaft 11 arranged on the central axis of the turntable box 1 and extending toward the negative direction of the Y-axis can be passed through the fixing hole, and the turntable box 1 is fixed on the mounting platform, and then a rotating gear 82 is sleeved on the circumferential surface of the rotating shaft 11, and a rotating motor 83 is arranged on the bracket 81. The rotating motor 83 is drivingly connected to the rotating gear 82. When the rotating motor 83 works, it drives the rotating gear 82 to rotate, and then drives the rotating shaft 11 and the turntable box 1 to rotate, thereby realizing the self-rotation of the turntable box 1.

[0045] Specifically, the rotating gear 82 is key-connected with the rotating shaft 11 , and the rotating shaft 11 may be a hollow structure. A second rotating joint is provided at one end of the rotating shaft 11 facing the negative direction of the Y axis.

[0047] In this embodiment, a first rotary joint 41 is provided at one end of the expansion and contraction cylinder 4 away from the reel 2. The first rotary joint 41 provides the expansion and contraction cylinder 4 with hydraulic oil for use during operation, thereby facilitating the expansion and contraction cylinder 4 to drive the reel 2 to tighten or expand.
