For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood through specific circumstances.

[0020] Please see Figure 1 And Figure 2 The utility model discloses a precise edge material winding device 1 is arranged at the slitting machine 2, the slitting machine 2 is provided with edge material winding rubber roller 21, the edge material winding device 1 is provided with tube core 11, the edge material winding device 1 is attached with the edge material winding rubber roller 21, wherein, the edge material winding rubber roller 21 is used to steady traction after the film edge material is cut, and the tube core 11 is used to roll up the film of the edge material winding rubber roller 21.

[0021] In the above embodiment, the edge material winding device 1 is directly attached to the edge material winding rubber roller 21, and this contact design enables the device to stabilize the tension change of the edge material winding rubber roller 21 when winding the film edge material. The main function of the edge material winding rubber roller 21 is to stably pull the cut film edge material, and the edge material winding device 1 ensures smooth force transmission during winding through direct contact with the rubber roller.

[0022] During winding, the diameter of the tube core 11 increases due to the winding of the film edge, and the pressure of the edge material winding rubber roller 21 increases. At this time, the contact force between the edge material winding device 1 and the edge material winding rubber roller 21 can be adjusted to avoid problems such as poor winding effect or film rupture caused by excessive tension fluctuation. In addition, the device also has high flexibility, and the distance between the two edge material winding devices 1 can be flexibly adjusted according to the actual need of cutting the edge film width. This design not only improves the winding efficiency, but also ensures the stability and consistency of the winding quality, providing a strong guarantee for the continuous and efficient operation of the film production line.

[0023] Please see Figure 1 In this embodiment, during the unwinding process of the unwinding mechanism 23, the cutting device 25 cuts the film, the cut film is wound in the winding mechanism 24, and the remaining film edge material is stably pulled by the edge material winding rubber roller 21. The edge material winding device 1 is attached to the edge material winding rubber roller 21, and the film edge material is wound to the tube core 11.

[0024] Please see Figures 2 to 4In another embodiment, the edge material winding device 1 comprises a swing arm 12, a rotating shaft 13, a flange 14, a winding chuck 15, and a pressing adjustment mechanism 16. The rotating shaft 13 is arranged at the first end of the swing arm 12, and the pipe core is arranged on the rotating shaft 13. The winding chuck 15 is arranged at the first end of the swing arm 12. The slitting machine 2 is provided with a support rod 22. The flange 14 is arranged at the second end of the swing arm 12, and the second end of the swing arm 12 penetrates the support rod 22. The pressing adjustment mechanism 16 is used to adjust the pressure of the rotating shaft 13 adhering to the edge material winding rubber roller 21.

[0025] In the above embodiment, the device mainly comprises the swing arm 12, the rotating shaft 13, the flange 14, the winding chuck 15, and the pressing adjustment mechanism 16.

[0026] In operation, the swing arm 12 serves as the support and transmission main body of the entire device. The first end of the swing arm 12 is provided with the rotating shaft 13, which expands the pipe core 11 to rotate. With the rotation of the edge material winding rubber roller 21, the rotating shaft 13 rotates synchronously to drive the pipe core 11 to rotate, and the film roll is wound to the pipe core 11, thereby realizing continuous winding of the film edge material. The winding chuck 15 is also arranged at the first end of the swing arm 12, which is used to fix and clamp the pipe core 11. The pipe core 11 serves as the winding carrier of the film edge material and continuously accumulates the film with the rotation of the rotating shaft 13.

[0027] The second end of the swing arm 12 penetrates the support rod 22 on the rack of the slitting machine 2 and is fixed and limited by the flange 14. This design not only ensures the stability of the swing arm 12 during winding, but also provides the necessary rotation freedom for the swing arm 12.

[0028] Especially worth mentioning is the pressing adjustment mechanism 16. By applying pressure to the swing arm 12, the swing arm 12 can closely adhere to the edge material winding rubber roller 21, thereby ensuring the smooth transmission and tight winding of the film edge material during winding. At the same time, in the initial state, the pipe core 11 adheres to the edge material winding rubber roller 21, and the pressure is small. During winding, the diameter of the pipe core 11 gradually increases, and the pressure between the collected roll material and the edge material winding rubber roller 21 increases synchronously. At this time, the pressing adjustment mechanism 16 adjusts the adhesion pressure between the collected roll material and the edge material winding rubber roller 21, ensures that the pressure of the collected roll material and the pipe core 11 in the initial state is consistent with the pressure of the edge material winding rubber roller 21, and thereby ensures the tension balance during winding.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5In another embodiment, the pressing adjusting mechanism 16 comprises a cylinder 161, a telescopic rod 162, and a clamping block 163. The cylinder 161 is used to drive the telescopic rod 162 to move forward and backward. The telescopic clamping block 163 is arranged at one end of the telescopic rod 162, and the clamping block 163 is fixedly connected to the swing arm 12.

[0030] In the above embodiment, the cylinder 161 serves as a power source to drive the telescopic rod 162 to perform linear reciprocating motion. One end of the telescopic rod 162 is provided with the clamping block 163, which is fixedly connected to the swing arm 12. When the cylinder 161 drives the telescopic rod 162 to move forward, the clamping block 163 pushes the swing arm 12, so that the rotating shaft 13 or the winding chuck 15 closely contacts the edge material winding rubber roller 21, thereby increasing the pressure between them. Conversely, when the cylinder 161 drives the telescopic rod 162 to move backward, the pushing force of the clamping block 163 on the swing arm 12 decreases, and the pressure between the pipe core 11 and the edge material winding rubber roller 21 also decreases. In this way, the pressing adjusting mechanism 16 can control the swing arm 12, so as to accurately control the close-fitting pressure between the pipe core 11 and the edge material winding rubber roller 21.

[0031] Further, in another embodiment, a group of swing arms 12 are controlled by one cylinder 161.

[0032] In the above embodiment, the synchronous motion of the two swing arms 12 and the rotating shafts 13 thereon can be realized, so as to ensure that the pressure applied by the edge material winding device 1 on the edge material winding rubber roller 21 is uniform, and improve the winding effect. At the same time, the control system is simplified, the energy consumption is reduced, and the stability and reliability of the overall device are improved.

[0033] Please refer to Figure 3 , Figure 4 and Figure 5 , the pressing adjusting mechanism 16 further comprises an electrical proportional valve.

[0034] In the above embodiment, the cylinder 161 controls the air intake amount through the electrical proportional valve. During the winding process, as the diameter of the material roll increases and the weight increases, the electrical proportional valve receives the corresponding signal and automatically adjusts the air intake amount to increase the output force of the cylinder 161. The piston rod of the cylinder 161 pushes the clamping block 163 on the swing arm 12, so that the rotating shaft 13 applies greater buffer force to the material roll, so as to ensure that the contact force between the material roll and the edge material winding rubber roller 21 is always in a small range. This dynamic adjustment mechanism can ensure that the rewinding material will not be deformed due to excessive tension during the winding process, thereby ensuring the winding quality and the stability of the product.

[0035] Please refer to Figure 4 , the clamping block 163 is threadedly connected to the swing arm 12.

[0036] In the above embodiment, it is convenient to install and disassemble, and different specifications or worn clamping blocks 163 can be quickly replaced according to actual needs; at the same time, the threaded connection can provide stable connection force, ensure that the clamping block 163 will not be loose or fall off due to excessive force during the rolling process, and ensure the stability and safety of the rolling.

[0037] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belong to the scope of the present application.
