Therefore, they should not be construed as limitations on the present invention.

[0024] like Figures 1 to 3 As shown, a device for facilitating sidewall rewinding includes a release station 1 for releasing the material and a winding station 2 for winding the material. An auxiliary mechanism is provided between the release station 1 and the winding station 2. The material on the release station 1 is supported and transferred by the auxiliary mechanism and is wound and rewound to the winding station 2 for rewinding.

[0025] By adding an auxiliary mechanism between the unwinding station 1 and the winding station 2 as a supporting transition stage, the material is supported during the rewinding process. The sidewall enters the rewinding station 2 smoothly from the unwinding station 1 through the supporting tensioning action of the auxiliary mechanism, and the rubber material is introduced into the rewinding direction requirement, avoiding the stretching or adhesion of the rubber material during the rewinding process, thereby greatly improving the quality of the rubber material after rewinding.

[0026] In the device for facilitating sidewall rewinding of this embodiment, the auxiliary mechanism includes a first auxiliary roller group 3, which includes a plurality of first auxiliary rollers. The plurality of first auxiliary rollers are of equal height and are respectively arranged perpendicular to the rubber material conveying direction.

[0027] Specifically, multiple first auxiliary rollers are arranged at equal intervals, and their surfaces are arranged horizontally. When the material is transported above the first auxiliary roller group 3, the material drives the first auxiliary rollers to roll. At the same time, the first auxiliary rollers support and guide the material to ensure a smooth rewinding process.

[0028] Preferably, the first auxiliary roller is arranged perpendicular to the conveying direction, so that the rolling direction of the first auxiliary roller can drive the material to move in the rewinding direction, thereby ensuring the guiding and supporting effects and preventing the material from wrinkling.

[0029] The device for facilitating sidewall rewinding of this embodiment further includes a frame 4, a deflecting spool 5 detachably connected to the frame 4 is installed on the deflecting station 1, a winding spool 6 detachably connected to the frame 4 is installed on the winding station 2, and a first auxiliary roller is rotatably connected to the frame 4.

[0030] The frame 4 is provided to support and limit the entire device, and the unwinding and curling are achieved through the I-wheel, which is convenient for rotating to drive the material to open and rewind. At the same time, the detachable setting is convenient for replacing the material roller and improving the rewinding efficiency.

[0031] Preferably, the unwinding spool 5 and the curling spool 6 are driven to move by loading and unloading cylinders respectively to adjust the positions of the spool and the frame 4, thereby reducing the manual burden.

[0032] In the device for facilitating sidewall rewinding of this embodiment, a driving mechanism is respectively provided on the unwinding station 1 and the winding station 2, and the driving mechanism drives the unwinding spool 5 and the winding spool 6 to rotate to realize unwinding and rewinding of the material.

[0033] Specifically, the driving mechanism includes a variable frequency motor 9 and a coupling, and the unwinding spool 5 and the winding spool 6 are respectively connected to the variable frequency motor 9 through the coupling.

[0034] A variable frequency motor 9 and a coupling are provided to drive the unwinding spool 5 and the winding spool 6 on both sides to rotate synchronously, thereby realizing simultaneous unwinding and winding, avoiding stretching or adhesion of the material during the conveying movement, which affects the normal use of the material; the rewinding device in this application also includes a background host, which controls the start and stop of the variable frequency motors 9 on both sides to ensure synchronization.

[0035] In the device for facilitating sidewall rewinding of this embodiment, the frame 4 includes a supporting frame and a movable frame, the first auxiliary roller is mounted on the movable frame, and the distance between the movable frame and the supporting frame is adjustable.

[0036] Specifically, by setting up a movable frame and a support frame, adjusting the distance between the two to change the height of the first auxiliary roller, thereby matching the gradually changing material thickness on the unwinding spool 5 and the winding spool 6, adjusting the height of the movable frame and the first auxiliary roller as the rewinding proceeds to ensure that the first auxiliary roller effectively supports and unfolds the material, thereby preventing the material from falling off the first auxiliary roller.

[0037] Preferably, the movable frame can be adjusted in height up and down by providing a telescopic cylinder at the bottom, or a screw rod can be provided to rotate and telescope to achieve adjustment of the movable frame, which is not limited here.

[0038] In the device for facilitating sidewall rewinding of this embodiment, a cloth guiding-out station is provided below the first auxiliary roller group 3, and a cloth support shaft 7 for installing a cloth roller is provided on the cloth guiding-out station. The cloth support shaft 7 rotates to drive the cloth roller to guide the cloth out.

[0039] Specifically, the provision of a cloth guide-out station increases the functionality of the rewinding device of the present application, enabling cloth rewinding, expanding its scope of application, and improving its practicality. The cloth support shaft 7 is mounted on a support frame within the frame 4, and a variable frequency motor 9 is also connected to its end. When the cloth is rewinding, a corresponding cloth rewinding pulley is provided on the rewinding station 2.

[0040] By arranging the cloth guiding station below the first auxiliary roller group 3, it adapts to the structural characteristics of the cloth roller with a small volume, realizes the cloth rewinding, fully utilizes the space, and makes the overall device more compact.

[0041] In the device for facilitating sidewall rewinding of this embodiment, the auxiliary mechanism also includes a second auxiliary roller group 8, which is located between the first auxiliary roller group 3 and the winding station 2. The padding guided away by the padding roller is supported by the second auxiliary roller group 8 and enters the winding station 2 for winding.

[0042] Specifically, a second auxiliary roller group 8 is provided to support and guide the rewinding of the pad cloth. The pad cloth is led out from the bottom of the first auxiliary roller group 3 through the second auxiliary roller group 8 and connected to the pad cloth winding wheel to realize reversing winding.

[0043] Preferably, the height of the second auxiliary roller group 8 can also be adjusted. When rewinding the rubber material, the second auxiliary roller group 8 and the first auxiliary roller group 3 are used in conjunction with each other to adjust the height synchronously to facilitate the rewinding of the rubber material; at the same time, the second auxiliary roller group 8 can be adjusted up and down independently to adapt to the rewinding operation of the pad cloth.

[0044] In the device for facilitating sidewall rewinding of this embodiment, the second auxiliary roller group 8 includes a horizontal roller segment arranged horizontally and a downwardly curved arc roller segment. The arc roller segment is located on the side of the horizontal roller segment close to the first auxiliary roller group 3 to receive the padding cloth guided away by the padding cloth roller.

[0045] Specifically, an arc-shaped roller segment is arranged to match the installation position of the cloth pad roller, which plays a transitional role in the movement of the cloth pad, facilitates the rewinding of the cloth pad on the cloth pad roller installed at a lower position, and avoids excessive pulling of the cloth pad by the angle between the cloth pad and the horizontal roller segment, which affects the quality of the cloth pad.

[0046] In the device for facilitating sidewall rewinding of this embodiment, a photoelectric sensor 10 is provided on the peripheral side of the auxiliary mechanism, and the photoelectric sensor 10 is signal-connected to the variable frequency motor 9. The photoelectric sensor 10 and the variable frequency motor 9 are respectively controlled and connected to the background host.

[0047] Specifically, a photoelectric sensor 10 is set to detect the material transported on the auxiliary mechanism. When it is detected that there is material on the auxiliary mechanism, the background host controls the frequency conversion motor 9 to drive the I-wheel to rotate for unwinding and winding. When it is detected that there is no material, the frequency conversion motor 9 is controlled to stop at the same time to prevent the material on the curling station from loosening.

[0048] Preferably, the photoelectric sensor 10 is arranged at one end of the auxiliary mechanism close to the curling station 2 and is located below the auxiliary mechanism and perpendicular to the material to improve detection accuracy.
