[0026] To describe in detail the technical content, structural features, achieved objectives and functions of the present application, the following will describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0027] In the present application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (for example, as in "side wall") are used to describe the relationship between one element and another (other) element as shown in the drawings. The spatial relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped, the element described as "under" or "beneath" other elements or features will then be positioned "above" the other elements or features. Thus, the exemplary term "under" can include both the above and below orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or in other orientations), and accordingly, the spatial relative descriptive terms used herein are interpreted.

[0028] In the present application, the term "axial direction" means the axial line direction of the output shaft; the term "radial direction" means the radial direction of the output shaft.

[0029] Figure 1-2 Shown is the waste edge winding device 100 provided by the present utility model, which can be configured on any ground of the sheet production line or on the sheet trimming equipment to wind the waste edge cut from the sheet. Specifically, the waste edge winding device 100 includes a support frame 1 providing support, a power mechanism mounted on the support frame 1, and a winding mechanism for winding the waste edge.

[0030] Continue to refer to Figure 1-2 , the support frame 1 includes an installation part 11 at the bottom and a support part 12 at the top. A plurality of bolt holes (not marked in the figure) for locking the anchor bolts are provided on the installation part 11 to firmly lock the waste edge winding device 100 to the ground or any sheet production equipment. It can be understood that in other embodiments, the waste edge winding device can also be fixed by various methods such as welding and plugging.

[0031] The support part 12 of the support frame 1 provided in this embodiment is a vertically extending column. Combining Figure 3 , the power mechanism of the waste edge winding device 100 includes a winding motor 21, a reduction gearbox 22, and an output shaft 23. The reduction gearbox 22 includes a box body (not marked in the figure) and transmission components (not shown in the figure) accommodated inside the box body. The box body of the reduction gearbox 22 is fixedly installed on the top of the support part 12 of the support frame 1, and the output shaft 23 is rotatably supported on the reduction gearbox 22 and is in transmission connection with the transmission components inside the reduction gearbox 22. Thus, the output shaft 23 is rotatably mounted on the support frame 1 via the reduction gearbox 22.

[0032] The winding motor 21 includes a motor housing (not marked in the figure) fixedly installed on the box body of the reduction gearbox 22 and a rotatable motor shaft (not shown in the figure). The motor shaft of the winding motor 21 extends into the inside of the reduction gearbox 22 and forms a transmission connection with its transmission components. Thus, the winding motor 21 is mounted on the support frame 1 via the reduction gearbox 22 and forms a transmission connection with the output shaft 23 to drive the output shaft 23 to rotate.

[0033] Continue to refer to Figure 1 And Figure 4 , the winding mechanism of the waste edge winding device 100 includes a turntable 31 fixedly installed on the output shaft 23, a plurality of link units movably installed on the turntable 31, a connection head 34 for driving each group of link units to move, and a limiting plate 35 for limiting the link units. Specifically, the above-mentioned link unit includes a first link 32 rotatably connected to the axial end face of the turntable 31 and a second link 33 rotatably connected to the end of the first link 32 away from the turntable 31. The end of the second link 33 away from the first link 32 is rotatably connected to the connection head 34.

[0034] The waste edge winding device 100 has a winding state in which the first and second links form a first included angle α1 (such asFigure 4 Preferably, the first included angle α1 is 90°). In this state, the winding motor 21 drives the turntable 31, multiple sets of link units, and the limiting plate 35 to rotate together through the output shaft 23, and the waste edge is wound on the outer end face of the first link 32. In addition, the waste edge winding device 100 further has a unwinding state in which the first and second links form a second included angle α2 greater than the first included angle α1 (such as Figure 5 Preferably, the second included angle α2 is any angle within the range of 100° - 130°). In this state, the first and second links contract radially inward relative to the winding state, and a gap is generated between the waste edge roll wound on the second link 32 and the second link 32, so that the staff can conveniently draw out the waste edge roll along the axial direction.

[0035] The connector 34 is movably mounted on the output shaft 23 in the axial direction, thereby driving the first and second links to move, so that the waste edge winding device 100 can switch back and forth between the winding state and the unwinding state. Specifically, the connector 34 has a hinge seat 341 for rotatably connecting each second link 33, a gripping portion 342 suitable for the staff to grip to push and pull the connector 34, and a locking portion (not shown in the figure). The above-mentioned locking portion can selectively lock the connector 34 on the output shaft 23 to prevent the connector 34 from shifting and unlock the connector 34 from the output shaft 23 to facilitate the staff to drive the connector 34 to move. The locking portion can be installed on the output shaft through various fitting methods such as screw fitting, plug-in fitting, and snap fitting. The above are all prior arts and are not limited herein.

[0036] The limiting plate 35 is mounted on the output shaft 23 and is located inside the first and second links. The limiting plate 35 is configured such that when the waste edge winding device 100 is in the winding state, the axial end face of the limiting plate 35 contacts the second link 33 or / and the connector 34 to limit the position of the second link 33 (i.e., limit the position of the connector 34 and the angle of the first included angle α1).

[0037] Further, the limiting plate 35 is configured to be movably mounted on the output shaft 23 in the axial direction to adjust the size of the above-mentioned first angle α1. It can be understood that "movably in the axial direction" here means that the limiting plate 35 can selectively move along the output shaft 23 and be fixed on the output shaft 23.

[0038] Further, a plurality of axially extending chutes 231 are provided on the output shaft 23, and the connector 34 is slidably engaged with the chutes 231. The chutes 231 are configured to limit the stroke of the connector 34 (this stroke means the maximum distance of the connector 34 away from the turntable 31) to limit the above-mentioned second angle α2.

[0039] Furthermore, the coiling mechanism further includes a plurality of fixing blocks 36 fixed on the axial end face of the turntable 31. The end of the first connecting rod 32 away from the second connecting rod 33 is rotatably connected to the fixing block 36. Among them, the fixing block 36 can be installed on any axial end face of the turntable 31. In this embodiment, it is shown as being installed on the axial end face of the turntable 31 close to the coiling motor 21. In other embodiments, a hinge seat, a pivot, etc. for the first connecting rod to be rotatably connected can also be provided on the turntable to replace the above-mentioned plurality of fixing blocks.

[0040] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it accordingly. It should not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
