[0025] The following reference Figures 1 to 4 This application describes a winding apparatus according to some embodiments.

[0026] This application provides a winding device, such as Figure 1 and Figure 2 As shown, the winding device includes a main shaft mechanism 1 and a smoothing mechanism 2.

[0027] The spindle mechanism 1 includes a spindle 11, which is rotatable about its own axis to wind the roll material onto the spindle 11. Specifically, the spindle mechanism 1 also includes a spindle 11 drive device, the drive end of which is connected to the spindle 11 to drive the spindle 11 to rotate, so that the roll material can be wound onto and wound onto the spindle 11.

[0028] The smoothing mechanism 2 includes a smoothing roller 23, a connecting rod assembly, a first driving device 21, and a second driving device 22. The smoothing roller 23 is arranged parallel to each other on one side of the main shaft 11 in the radial direction, and is mounted to the driving end of the first driving device 21 via the connecting rod assembly. This allows the smoothing roller 23 to move linearly under the drive of the first driving device 21, moving closer to or away from the main shaft 11. For example, when the main shaft 11 is placed horizontally, the smoothing roller 23 is suspended obliquely above the main shaft 11, and the first driving device 21 can drive the smoothing roller 23 to move linearly in the vertical direction, moving closer to or away from the main shaft 11. Therefore, when the main shaft 11 is used to wind up the roll material, the first driving device 21 can drive the smoothing roller 23 to move closer to or away from the main shaft 11, causing the smoothing roller 23 to press against the roll material on the main shaft 11, providing pressure to the roll material and adjusting the pressure acting on it.

[0029] The linkage assembly includes a first link 25 and a second link 26. The first link 25 is mounted on the drive end of the first drive device 21. One end of the second link 26 is connected to the smoothing roller 23, and the other end of the second link 26 is pivotally connected to the first link 25 via a pivot parallel to the main shaft 11. The second link 26 can rotate around the pivot under the drive of the second drive device 22, thereby causing the smoothing roller 23 to swing, bringing it closer to or away from the main shaft 11. Thus, when the main shaft 11 is used to wind up the roll material, the second drive device 22 can be used to drive the smoothing roller 23 closer to or away from the main shaft 11, causing the smoothing roller 23 to press against the roll material on the main shaft 11, thereby providing pressure to the roll material and adjusting the pressure acting on the roll material.

[0030] Therefore, during the winding process, the movement of the smoothing roller 23 can be controlled collaboratively by the first drive device 21 and the second drive device 22, so as to precisely and flexibly adjust the pressure of the smoothing roller 23 on the main shaft 11 of the roll material according to the different roll materials and the changes in roll diameter during the winding process. At the same time, after winding is completed, the smoothing roller 23 can be lifted conveniently and quickly to realize roll changing.

[0031] In one embodiment of this application, preferably, the second driving device 22 has a fixed end and a retractable driving end. One of the driving end and the fixed end of the second driving device 22 is hinged to the first connecting rod 25, and the other is hinged to the second connecting rod 26. The pivots at both hinge points are parallel to the main shaft 11. Thus, when the driving end of the second driving device 22 extends or retracts, the second connecting rod 26 can drive the smoothing roller 23 to swing, causing the smoothing roller 23 to move closer to or away from the roll material on the main shaft 11.

[0032] In one embodiment of this application, preferably, as Figure 2 As shown, the smoothing mechanism 2 also includes a pressure sensor 27. The smoothing roller 23 is mounted on the roller seat 24, allowing the smoothing roller 23 to rotate around its own axis. The roller seat 24 is mounted on the second connecting rod 26 via the pressure sensor 27, so that the pressure of the smoothing roller 23 acting on the roll material of the main shaft 11 can be detected by the pressure sensor 27. This allows the first drive device 21 and the second drive device 22 to adjust the smoothing roller 23 according to the detection results of the pressure sensor 27, so that the pressure of the smoothing roller 23 acting on the roll material can be flexibly controlled in real time according to the different materials of the roll material and the changes in the roll diameter during the winding process.

[0033] In one embodiment of this application, preferably, as shown below, Figure 2 As shown, the first driving device 21 is an electric slide table, which enables the smoothing roller 23 to provide the required pressure to the roll material on the main shaft 11 under the action of the first driving device 21, and the smoothing roller 23 can be quickly lifted after winding is completed to perform roll changing operation.

[0034] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the winding device also includes a correction mechanism 3 to prevent the incoming material of the roll from deviating from the main shaft 11 along a first direction, the first direction being the axial direction of the main shaft 11.

[0035] In this embodiment, the web-correcting mechanism 3 includes a web-correcting drive 31 and a web-correcting detection component. The web-correcting detection component is located on the feeding side of the web and is used to detect the offset of the web along the first direction on the feeding side of the web. The web-correcting drive 31 is used to drive the spindle mechanism 1 to move along the first direction according to the above-mentioned detection value, so as to bring the offset to zero, thereby ensuring that the web can be smoothly wound onto the spindle 11.

[0036] In this embodiment, preferably, as follows: Figure 3 As shown, the winding device includes a slide 12, which is slidably disposed along a first direction, and a main shaft mechanism 1 is mounted on the slide 12. The web-correcting drive 31 includes a fixed end and a retractable drive end. One of the fixed end and the drive end of the web-correcting drive 31 is fixedly disposed, and the other end is connected to the slide 12, so that the web-correcting drive 31 can drive the slide 12 and the main shaft mechanism 1 disposed on the slide 12 to move along the first direction to achieve web correction.

[0037] In this embodiment, preferably, as follows: Figure 3 As shown, the web guiding detection assembly includes a web guiding sensor 32, a support member 33, and a connecting assembly. The web guiding sensor 32 is mounted on the support member 33 via the connecting assembly to fix the web guiding sensor 32 at a predetermined position. The web guiding sensor 32 has a detection area through which the incoming web material passes to detect the position of the web material. The web guiding sensor 32 can upload the detection results to the control system of the winding device so that the control system can determine whether the incoming web material has deviated.

[0038] In this embodiment, the position of the connecting component on the support 33 is adjustable along the first direction, thereby enabling adaptive adjustment of the position of the web correction sensor 32 according to the different sizes of the roll material.

[0039] In this embodiment, preferably, as follows: Figure 3 As shown, the connecting assembly includes an adjusting block 34, a fixing block 35, and a transmission screw 36. The correction sensor 32 is slidably connected to the support member 33 along the first direction via the adjusting block 34. The transmission screw 36 is arranged along the first direction. One end of the transmission screw 36 is connected to the support member 33 via the fixing block 35, and the transmission screw 36 can rotate around its own axis. The other end of the transmission screw 36 is screwed to the adjusting block 34. By turning the transmission screw 36, the adjusting block 34 can drive the correction sensor 32 to slide along the first direction to adjust the position of the correction sensor 32.

[0040] In this embodiment, preferably, as follows: Figure 3 As shown, the correction detection component also includes a position display 37, which is coaxially connected to the transmission screw 36 and mounted on the fixing block 35. The position display 37 can display different scales according to the different rotation angles of the transmission screw 36, thereby marking the position of the correction sensor 32.

[0041] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 3 As shown, the main shaft mechanism 1 also includes a main shaft fixing seat 13, with one end of the main shaft 11 rotatably connected to the main shaft fixing seat 13. The winding device also includes a fixing plate 5, which is connected to the main shaft fixing seat 13. The smoothing mechanism 2 and the correction detection component are located on opposite sides of the main shaft 11 in the radial direction, and are respectively mounted on the fixing plate 5. Thus, when the correction drive 31 drives the main shaft mechanism 1 to move for correction, it can drive the smoothing mechanism 2 and the correction detection component to move synchronously, so as to ensure that the relative position of the smoothing roller 23 and the main shaft 11 in the first direction, as well as the relative position of the correction sensor 32 and the main shaft 11 in the first direction, are not affected.

[0042] In one embodiment of this application, preferably, as shown below, Figure 4 As shown, the winding device also includes a feeding mechanism 4, which includes a pusher block 42, a pusher plate 41, and a feeding drive device 43. Push block 42 is fixed on push plate 41. Push block 42 has a through mounting hole. The diameter of the mounting hole is larger than the diameter of spindle 11, so that spindle 11 can move through push block 42. The drive end of unloading drive device 43 is connected to push plate 41. Unloading drive device 43 can drive push plate 41 to move in the first direction, so that push block 42 can be used to push the coil material that has been wound on spindle 11 away from spindle 11 to complete unloading of the coil material.

[0043] In this embodiment, preferably, when the roll material is wound, a mandrel is fitted on the main shaft 11, and the roll material is wound around the mandrel. The push block 42 is adapted to the mandrel, so that when the roll material is unloaded, the push block 42 acts on the mandrel, pushing the mandrel and the roll material wound on it away from the main shaft 11 together, thereby avoiding the push block 42 acting on the roll material and damaging the roll material.

[0044] In this embodiment, preferably, as follows: Figure 4As shown, the feeding mechanism 4 also includes a guide rod 44 and a linear bearing 45. The guide rod 44 is arranged along the first direction, with one end of the guide rod 44 mounted on the linear bearing 45 and the other end of the guide rod 44 connected to the push plate 41. Thus, when the feeding drive device 43 drives the push plate 41 to move, the guide rod 44 can guide the linear motion of the push plate 41, avoiding collision with the main shaft 11.

[0045] Preferably, there are multiple feeding drive devices 43, which are arranged at intervals along the circumference of the push plate 41, so as to provide uniform thrust for the linear motion of the push plate 41 by using multiple feeding drive devices 43.

[0046] Preferably, there are multiple guide rods 44, which are spaced apart along the circumference of the push plate 41. This allows the push plate 41 to be guided in linear motion, ensuring that the push plate 41 does not deviate during its movement.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
