[0030] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See attached Figures 1 to 4 As shown, a membrane filament end-sealing and slitting device in this embodiment includes an unwinding mechanism 2, a transmission mechanism 3, an end-sealing and slitting mechanism 4, and a rewinding mechanism 5. A rolled membrane filament 8 is placed on the unwinding mechanism 2. Under the action of the transmission mechanism 3, the membrane filament 8 is transmitted from the unwinding mechanism 2 to the rewinding mechanism 5. During the transmission process, the membrane filament 8 is cut and sealed by the end-sealing and slitting mechanism 4 to obtain a membrane filament 8 of a preset width. The cut membrane filament 8 is then rewound by the rewinding mechanism 5.

[0032] In some embodiments, a waste recovery structure 6 is also included. The waste recovery mechanism includes two symmetrically arranged waste recovery pipes, one end of the waste recovery pipe faces the cutter 43, and the waste membrane filament 8 cut by the cutter 43 is recovered through the waste recovery pipe.

[0033] In some embodiments, the transmission mechanism 3 and the end-sealing and slitting mechanism 4 are arranged on the workbench 1, and a protective cover 9 is provided above the transmission mechanism 3 and the end-sealing and slitting mechanism 4 to protect the transmission mechanism 3 and the end-sealing and slitting mechanism 4.

[0034] In some embodiments, the transmission mechanism 3 is disposed between the unwinding mechanism 2 and the rewinding mechanism 5. The transmission mechanism 3 includes a drive motor 31, which is fixed to the workbench 1 and connected to a rubber roller assembly 34 via a transmission assembly. The rubber roller assembly 34 includes two parallel rubber rollers. The membrane filament 8 passes through the gap between the two rubber rollers. The two parallel rubber rollers clamp the membrane filament 8 and thus transmit the membrane filament 8.

[0035] In some embodiments, the transmission mechanism 3 also includes a distance-adjusting cylinder 35, which is arranged on one side of the rubber roller and connected to a rubber roller. The distance-adjusting cylinder 35 can drive the rubber roller connected to it to move closer to or away from the other rubber roller, thereby adjusting the distance between the two rubber rollers in the rubber roller assembly 34. On the one hand, it is convenient to allow the membrane wire 8 to pass through the gap between the two rubber rollers before cutting. On the other hand, it can adjust the clamping force of the two rubber rollers on the membrane wire 8 during the transmission process, and then adjust it according to actual needs.

[0036] In some embodiments, two sets of rubber roller assemblies 34 are provided, one at the front and one at the back of the end-sealing and slitting mechanism 4. The two sets of rubber roller assemblies 34 facilitate the transport of the membrane filament 8 and also control the position of the membrane filament 8, allowing the membrane filament 8 to pass smoothly through the end-sealing and slitting mechanism 4.

[0037] In some embodiments, an encoder 7 is provided at one end of the rubber roller assembly 34. Through the setting of the encoder 7, the length of the cut film thread 8 can be counted, which facilitates the staff to control the cutting work as a whole.

[0038] In some embodiments, the transmission assembly includes a gear assembly 32, which includes two meshing gears. The two gears are respectively connected to the two rubber rollers in the rubber roller assembly 34. The output shaft of the drive motor 31 is connected to the gear assembly 32, and the drive motor 31 drives the gears to rotate, thereby driving the rubber rollers to rotate.

[0039] In some embodiments, two sets of gear assemblies 32 are provided, each connected to a rubber roller assembly 34. The two sets of gear assemblies 32 are connected by a transmission belt 33, allowing the drive motor 31 to simultaneously drive both sets of gear assemblies 32, and thus both sets of rubber roller assemblies 34. Having a single drive motor 31 drive both sets of rubber roller assemblies 34 simultaneously reduces the number of drive motors 31 and equipment costs, while also maintaining synchronized movement of the two sets of rubber roller assemblies 34.

[0040] In some embodiments, the transmission component also includes a transition roller 36, which is arranged parallel to the rubber roller. There are multiple transition rollers 36, which are located between the rubber roller assembly 34 and the unwinding mechanism 2, or between the rubber roller assembly 34 and the winding mechanism 5. They are used to limit the membrane wire 8 to ensure that the membrane wire 8 is transported along the set trajectory. On the other hand, they prevent friction between the membrane wire 8 and the workbench 1, thereby protecting the membrane wire 8 and the workbench 1.

[0041] In some embodiments, the transmission mechanism 3 further includes a limiting sheet metal 37 , which is disposed between the transition roller 36 and the rubber roller assembly 34 , and is used to limit the membrane filament 8 to prevent the membrane filament 8 from shifting left or right during transmission.

[0042] See attached Figure 3 and attached Figure 5 As shown, in some embodiments, the end-sealing and slitting mechanism 4 includes a cutter 43 and a rotating shaft 41. The rotating shaft 41 is arranged parallel to the rubber roller and connected to the drive motor 31 via a belt 42. The drive motor 31 drives the rotating shaft 41 to rotate, which in turn drives the cutter 43 to rotate. An ultrasonic generator 44 is located at the lower end of the cutter 43, and a cover plate 45 is located above the ultrasonic generator. The ultrasonic generator 44 vibrates the cover plate 45 at high frequencies. The membrane filament 8 is positioned between the cutter 43 and the cover plate 45. The cutter 43 rotates and the cover plate 45 vibrates at high frequencies to slit the membrane filament 8. During the slitting process, friction between the cutter 43 and the cover plate 45 generates heat, which seals the cut ends of the membrane filament 8. The arrangement of the ultrasonic generator 44 and the cutter 43 ensures that the ends of the membrane filament 8 are neatly cut, achieving effective cutting results. Furthermore, the membrane filament 8 is end-sealed during the cutting process.

[0043] In some embodiments, the end-sealing and slitting mechanism 4 includes a lifting cylinder 46, which is disposed on the workbench 1 and has a telescopic rod connected to the rotating shaft 41. The lifting cylinder 46 can drive the rotating rod to move in the vertical direction, thereby adjusting the distance between the cutter 43 and the cover plate 45. On the one hand, this facilitates passing the membrane filament 8 through the gap between the cutter 43 and the cover plate 45 before slitting. On the other hand, the distance between the cutter 43 and the support plate can also be adjusted according to the actual situation of cutting the membrane filament 8, so that the cutter 43 exerts a certain pressure on the cover plate 45, so that the cutter can cut the membrane filament 8.

[0044] In some embodiments, a heat sink 47 is provided above the cutter 43 for dissipating heat from the cutter 43 .

[0045] In some embodiments, the end-sealing and slitting mechanisms 4 are provided in two groups and are connected to a screw assembly 48. The screw assembly 48 can adjust the distance between the two groups of the end-sealing and slitting mechanisms 4. The screw assembly 48 includes a first guide rail 481, a first slider 482, and a first screw 483481 connected in sequence. The first screw 483 can drive the first slider 482 to move along the first guide rail 481. The first slider 482 is connected to the cutter 43, thereby changing the distance between the two groups of cutters 43, so that the end-sealing and slitting mechanisms 4 can cut and produce film strands 8 of different widths.

[0046] See attached Figure 3 and attached Figure 6 As shown, in some embodiments, the winding mechanism 5 includes a second slide rail 51, on which are disposed two symmetrically arranged second sliders 52. The two second sliders 52 can move closer to or further away from each other, thereby clamping and fixing a winding shaft 54 ​​for winding the film filament 8. The winding mechanism also includes a second screw rod 53 connected to the second sliders 52. The second screw rod 53 can control the position of the second sliders 52 on the second slide rail 51, thereby adjusting the distance between the two second sliders 52 to accommodate winding shafts 54 of different lengths.

[0047] In some embodiments, the winding mechanism 5 further includes a winding motor 55 and a clutch 56. The winding motor 55 is connected to the winding shaft 54, and the winding motor 55 drives the winding shaft 54 ​​to rotate. During the rotation of the winding shaft 54, the cut film filament 8 is wound. The clutch 56 is connected to the winding motor 55, and the setting of the clutch 56 ensures that the winding tension is within a set range.

[0048] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
