The phrase does not necessarily refer to the same embodiment at each occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides an automatic PVC film rewinding device, as Figures 1-4 shown. The automatic PVC film rewinding device includes: a base plate 1, on the top of which mounting plates 2 are symmetrically and fixedly installed; two first rotating shafts 3, which are respectively rotatably installed on the corresponding mounting plates 2; a first mounting disc 4 and a second mounting disc 5, which are respectively fixedly installed at one end of the corresponding first rotating shaft 3; a plurality of laterally adjustable mounting plates 10, which are all arranged on the first mounting disc 4; a plurality of winding rollers 6, which are arranged on the second mounting disc 5 and are used for winding the PVC film; a first motor 7 for driving the corresponding first rotating shaft 3 to rotate, the first motor 7 is arranged on the corresponding mounting plate 2, and a first gear 8 for transmission is fixedly installed on the output shaft of the first motor 7; a second gear 9, which is fixedly installed on the corresponding first rotating shaft 3, and the second gear 9 meshes with the first gear 8; a plurality of driving mechanisms for driving the corresponding winding rollers 6 to rotate, and the plurality of driving mechanisms are arranged on the corresponding mounting plates 10 and the second mounting disc 5.

[0022] It should be noted that in the production and processing process of PVC film, the winding stage is a crucial link. In this stage, the PVC film is tightly wound around the core to form a wound material that is convenient for storage and transportation. However, the current practice is to rely on manual labor to remove these heavy wound materials from the winding machine after the winding process is completed. This process not only requires the machine to stop, but also takes a relatively long time for each stop and removal; specifically, the process of stopping and removing the wound material includes the following steps: First, the operator needs to wait for the PVC film to be completely wound; then, they must carefully approach the running machine and remove the wound material from the winding machine; finally, they also need to carry the removed wound material to the designated storage area. This process is not only time-consuming, but also has certain requirements for the physical strength and skills of the operator; since each stop and removal will cause a temporary stagnation of the production line, this directly reduces the production efficiency. In addition, the long downtime will also result in waste of production capacity because the production line cannot continue to produce new products during this period. In summary, an automatic roll-changing device for PVC film is needed to solve the above problems;

[0023] In this embodiment, the base plate 1 serves as the support foundation of the entire device and is firmly installed in the working area; the assembly plates 2 are symmetrically fixed on the top of the base plate 1 and are used to support and install subsequent components; the first rotating shaft 3 is installed on the assembly plate 2 through rotating devices such as bearings to ensure its free rotation; the first mounting disk 4 and the second mounting disk 5 are respectively fixedly installed at both ends of the first rotating shaft 3 and serve as the core components for winding and changing rolls; a plurality of mounting plates 10 are horizontally adjustable on the first mounting disk 4 and are used to install and adjust the position of the driving mechanism; a plurality of winding rollers 6 are installed on the second mounting disk 5 and are used for actual winding of the PVC film; the first motor 7 is arranged on the assembly plate 2 and drives the first rotating shaft 3, the first mounting disk 4 and the second mounting disk 5 to rotate synchronously through the meshing transmission of the first gear 8 and the second gear 9; multiple groups of driving mechanisms are installed between the mounting plate 10 and the second mounting disk 5 and are used to drive the winding rollers 6 to rotate independently to realize the winding of the PVC film; when the PVC film on a certain winding roller 6 reaches the preset length or weight, the stepper first motor 7 is started to drive the first rotating shaft 3 to rotate, and another group of vacant winding rollers 6 starts to rotate under the drive of the driving mechanism to take over the full winding roller 6 and continue to wind the PVC film; the operator only needs to remove the full winding roller 6 after it is full and replace it with an empty winding roller 6 without the need to stop the machine.

[0024] In a further preferred embodiment of the present utility model, the driving mechanism includes: bearing seats 11 respectively and fixedly installed on the mounting plate 10 and the second mounting disc 5; a second rotating shaft 12 rotatably installed on the corresponding bearing seat 11; limiting sleeves 13 respectively and fixedly installed on the corresponding second rotating shaft 12 for assembling the winding roller 6; second motors 14 respectively and fixedly installed on the corresponding mounting plate 10, and the output shaft of the second motor 14 is fixedly connected to the corresponding second rotating shaft 12 through a coupling.

[0025] In this embodiment, the bearing seats 11 are respectively and fixedly installed on the mounting plate 10 and the second mounting disc 5, serving as the supporting points of the second rotating shaft 12 to ensure its stable and smooth rotation; the second rotating shaft 12 is rotatably installed on the corresponding bearing seat 11, serving as the direct driving shaft of the winding roller 6; the limiting sleeves 13 are respectively and fixedly installed on the corresponding second rotating shaft 12, and their main function is to assemble and fix the winding roller 6 to ensure that the winding roller 6 does not shift or fall off during rotation; the second motors 14 are respectively and fixedly installed on the corresponding mounting plate 10, serving as the driving sources of the winding roller 6. The output shaft of the second motor 14 is fixedly connected to the corresponding second rotating shaft 12 through a coupling to achieve direct power transmission; by directly driving the second rotating shaft 12 by the second motor 14, and then driving the winding roller 6 to rotate, precise control of the winding speed of the PVC film is achieved. This direct driving method reduces the loss and error in the power transmission process, and improves the accuracy and stability of winding.

[0026] In a further preferred embodiment of the present utility model, a cylinder 15 for regulating the lateral movement of the corresponding mounting plate 10 is fixedly installed on the first mounting disc 4, and the output rod of the cylinder 15 is fixedly connected to the mounting plate 10.

[0027] In this embodiment, the introduction of the cylinder 15 makes the lateral movement of the mounting plate 10 fast and accurate. During the roll change process, the operator can control the expansion and contraction of the cylinder 15 to regulate the mounting plate 10 and the corresponding limiting sleeve 13, so as to quickly release the limit on the winding roller 6, enabling convenient replacement. This process greatly shortens the roll change time and improves the continuity and production efficiency of the production line.

[0028] In a further preferred embodiment of the present utility model, an assembly shell for assembling the first motor 7 is fixedly installed on the assembly plate 2, and a heat dissipation port is opened on the assembly shell.

[0029] In this embodiment, the assembly shell provides a stable installation environment for the first motor 7. By opening a heat dissipation port on the assembly shell, an effective air convection channel can be formed to accelerate the dissipation of heat inside the motor.

[0030] In a further preferred embodiment of the present utility model, reinforcing ribs are symmetrically and fixedly installed on the base plate 1, and one end of each reinforcing rib is fixedly connected to the corresponding assembly plate 2.

[0031] In this embodiment, the reinforcing ribs, as important components connecting the base plate 1 and the assembly plate 2, can significantly enhance the structural stability of the entire device. By dispersing and transmitting stress, they effectively resist external loads and vibrations, preventing the device from deforming or loosening during operation. This improvement in stability helps ensure the long-term stable operation of the PVC film automatic rewinding device, and improves the reliability and safety of the production line.

[0032] In a further preferred embodiment of the present utility model, through holes are formed in the mounting plate 10, and the inner diameter of each through hole is adapted to the corresponding second rotating shaft 12.

[0033] In this embodiment, the inner diameter of the through hole is larger than the diameter of the second rotating shaft 12, providing sufficient space for the second rotating shaft 12 to rotate smoothly on the mounting plate 10 without being affected by friction or jamming.

[0034] In a further preferred embodiment of the present utility model, a plurality of support columns are symmetrically and fixedly installed at the bottom of the base plate 1, and foot pads are fixedly installed at the bottom ends of the support columns.

[0035] In this embodiment, the addition of the support columns significantly enhances the stability of the base plate 1. As the connection bridge between the base plate 1 and the ground, they can bear the gravity of the device above and external impact forces, ensuring that the entire PVC film automatic rewinding device does not shake or topple during operation. This improvement in stability helps ensure the accuracy and safety of the rewinding process.

[0036] In summary, the PVC film automatic rewinding device provided by this technical solution realizes the automatic rewinding process of the PVC film through the coordinated work of the first motor 7, the first rotating shaft 3, the first mounting disc 4, the second mounting disc 5, and multiple groups of driving mechanisms, greatly improving the production efficiency and continuity, and solving the problem that the slow rewinding efficiency affects the production efficiency in the current PVC film production and processing process.

This direct drive method reduces the loss and error in the power transmission process, and improves the accuracy and stability of winding; through modular designs such as the laterally adjustable mounting plate 10 and the easily replaceable winding roller 6, the device structure is flexible, can be quickly adjusted and optimized according to production requirements, reducing the failure rate and maintenance cost; the introduction of the cylinder 15 makes the lateral movement of the mounting plate 10 fast and accurate, facilitating the quick release of the limit on the winding roller 6, realizing convenient replacement, shortening the roll-changing time, and improving the continuity and efficiency of the production line.
