[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] like Figures 1 to 6 As shown, this embodiment provides a winding mechanism for quick mold changing, including: Support frame 1 is the basic load-bearing structure of the entire winding mechanism, and is independently and fixedly set on the foundation. Support shaft 2 is fixedly installed in the connection hole of support frame 1; Hollow shaft 3, rotatably mounted on support shaft 2, is the core rotating component for realizing dual-station switching. A connecting frame 4 is provided at the end of hollow shaft 3, and the connecting frame 4 is set as a U-shaped structure. Two mounting mechanisms 5 are symmetrically and rotatably mounted at both ends of the connecting frame 4. The mounting mechanisms 5 are used to install the take-up roller. One of the two mounting mechanisms 5 is located in the winding area, and the other is located in the replacement area. Adjustment mechanism 6 is installed on support frame 1. Adjustment mechanism 6 is used to adjust the two mounting mechanism 5 positions on hollow shaft 3 to realize position switching. Drive mechanism 7, mounted on support frame 1, is used to provide rotational power to mounting mechanism 5 in the winding area; In this embodiment, the support frame 1 provides a stable foundation for the overall structure. The support shaft 2 is fixed in the connecting hole of the support frame 1, providing support for the rotation of the hollow shaft 3. The hollow shaft 3 serves as the core component for dual-station switching. Two mounting mechanisms 5 are symmetrically installed on the U-shaped connecting frame 4 at its end, so that when one is in the winding area for winding operations, the other can complete the replacement preparation of the take-up roller in the replacement area, reducing downtime. The adjustment mechanism 6 can conveniently adjust the positions of the two mounting mechanisms 5 to achieve rapid switching. The drive mechanism 7 provides stable rotational power to the mounting mechanism 5 in the winding area, ensuring winding efficiency. The overall structure takes into account both winding continuity and mold changing convenience, greatly improving production efficiency and enhancing the flexibility of the equipment.
[0018] As a preferred embodiment of the above technical solution, such as Figures 1 to 6 As shown, the mounting mechanism 5 includes: Connector 51 is rotatably mounted on one end of connector 4, and connector 51 is provided with a fixed seat 52; The mounting roller 53 is connected to the fixed seat 52 by a thread, and the mounting roller 53 is used to position and support the take-up roller. The clamping member 54 has a fastener 55 rotatably mounted on it. The fastener 55 is connected to the external thread at the end of the mounting roller 53. The clamping member 54 cooperates with the fixed seat 52 to clamp the take-up roller. In this embodiment, the connector 51 is rotatably mounted on one end of the connector frame 4, providing a rotational base for the mounting structure. By changing the size of the mounting roller 53, it can accommodate different sizes of take-up rollers. The clamping member 54 cooperates with the fixed seat 52. With the help of the rotatably mounted fastener 55 and the external thread connection at the end of the mounting roller 53, the take-up roller can be quickly clamped to ensure that the take-up roller does not shift during winding. The threaded connection makes installation and disassembly operations convenient. With the dual-station design, the clamping preparation of the take-up roller can be completed in advance in the changing area. It can be put into use directly when the station is switched, which greatly shortens the mold change time and improves the efficiency of winding operations.
[0019] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the drive mechanism 7 includes: The drive shaft 71 is rotatably installed inside the through hole of the support shaft 2. The axis of the drive shaft 71 is parallel to the axis of the support shaft 2 and is eccentrically set. The drive shaft 71 is equipped with a drive bevel gear 72. Two driven bevel gears 73 are coaxially mounted on two connecting pieces 51 respectively. The driven bevel gear 73 located in the take-up area meshes with the driving bevel gear 72. The power mechanism 74 is mounted on the support frame 1 and is used to provide rotational power to the power shaft 71. In this embodiment, the power shaft 71 is rotatably installed in the through hole of the support shaft 2. Its eccentric axis design, which is parallel to the support shaft 2, and its active bevel gear 72 can precisely mesh with the driven bevel gear 73 on the winding area connector 51 to ensure efficient power transmission. The two driven bevel gears 73 are coaxially installed on the two connectors 51 respectively, and only the winding area meshes with the active bevel gear 72 to achieve single-station targeted drive, avoiding the idle rotation of the mounting mechanism 5 when not in operation, so as to facilitate the disassembly and assembly of the take-up roller. The power mechanism 74 provides continuous power to the power shaft 71 to ensure stable winding speed. The dual-station design can still quickly establish effective transmission after the station is switched to ensure continuous and stable winding operation.
[0020] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the power mechanism 74 includes: Motor frame 74a is mounted on support frame 1, and drive motor 74b is mounted on motor frame 74a; The drive gear 74c is installed at the output end of the drive motor 74b; Driven gear 74d is coaxially mounted on drive shaft 71, and driven gear 74d meshes with drive gear 74c.

In this embodiment, the motor frame 74a securely mounts the drive motor 74b onto the support frame 1, ensuring stable power output. The drive gear 74c at the output end of the drive motor 74b meshes with the driven gear 74d on the power shaft 71, achieving efficient power transmission. The isolator 74e encloses the drive gear 74c and the driven gear 74d, preventing dust and impurities from entering the meshing area, reducing gear wear, and ensuring continuous winding operations.

In this embodiment, the servo motor 61 is mounted on the support frame 1, and the worm 62 at its output end meshes with the worm wheel 63 on the hollow shaft 3. With the help of the auxiliary component 64, the worm 62 is positioned and supported to ensure stable transmission. The servo motor 61 can drive the hollow shaft 3 to rotate precisely 180° through the meshing of the worm wheel 63 and the worm 62 in a single start, so that the two mounting mechanisms 5 can quickly exchange the positions of the winding area and the replacement area. The worm wheel 63 and worm 62 transmission has self-locking property, which can stably maintain the position of the hollow shaft 3 after the work position is switched, and avoid the work position shift caused by vibration during operation. The precise control of the servo motor 61 ensures that the rotation angle is accurate, and ensures that the transmission connection between the winding area mounting mechanism 5 and the drive mechanism 7 is accurate after the switch. The overall structure improves the convenience of work position switching.

[0023] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, a base 8 is provided at the bottom of the support frame 1, and an adjusting foot 9 is provided on the base 8; In this embodiment, the base 8 at the bottom of the support frame 1 increases the contact area with the foundation, improving the overall installation stability of the mechanism.
