Description

Technical Field

[0001] This utility model relates to the field of thin film industrial paper tube technology, specifically a thin film industrial paper tube with an anti-winding structure. Background Technology

[0002] With the rapid development of technology, the application of thin film industry in many fields is becoming increasingly widespread, from electronics and electrical appliances, machinery manufacturing to printing and packaging, and new energy industries. Various thin film materials, with their unique properties such as thinness, transparency, insulation, and barrier properties, have become indispensable key materials. In the production, transportation, and storage of thin films, paper tubes, as commonly used supports and winding carriers, play a vital role. Industrial paper tubes are the core carrier for winding thin films during production, processing, and storage; their performance directly affects the flatness, density, and subsequent processing efficiency of the film roll.

[0003] Chinese Patent Publication No. CN215710816U discloses a paper tube for the film industry, including a first paper tube and an adjusting assembly disposed on the first paper tube. The first paper tube has a groove. The adjusting assembly includes a threaded rod, a second paper tube, and a protective sleeve. The first paper tube is connected to the threaded rod, and the end of the threaded rod away from the first paper tube is fitted inside the second paper tube. The protective sleeve is installed on the second paper tube, covering the outer surface of the threaded rod, with the end of the protective sleeve away from the second paper tube positioned within the groove. By adjusting the assembly, the size of the paper tube can be adjusted, facilitating the collection of films of various sizes.

[0004] In the existing technology, the paper tube used in the film industry can only adjust the size to fit films of different widths, and lacks auxiliary optimization functions for the winding process. After winding, the film is prone to problems such as misalignment between multiple layers and uneven edges. In scenarios with high requirements for film winding quality, its applicability is weak and it is difficult to meet the needs of high-precision production. Therefore, we have made improvements and proposed a paper tube for film industry with an anti-winding structure. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] (1) By combining the pump, fixed pipe, connecting pipe and air outlet, air can be blown out through the air outlet during winding (or negative pressure adsorption is formed, depending on the actual airflow direction), so that the film adheres more tightly to the paper tube during winding, reducing the generation of bubbles and wrinkles, improving the tightness of film winding, and at the same time, the airflow pressure helps the film to remain flat, thus initially achieving the anti-winding function.

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3. A thin-film industrial paper tube with an anti-winding structure includes a first paper tube 1. Side plates 3 are provided on both sides of the first paper tube 1. A second paper tube 2 is fixedly installed on the side of the two side plates 3 that are close to each other. The two second paper tubes 2 are slidably connected to the first paper tube 1. Fixing blocks 4 are fixedly installed on the side of the two side plates 3 that are close to each other. The two fixing blocks 4 are inserted into the interior of the first paper tube 1 and slidably connected to it. A pump 6 is fixedly installed inside the first paper tube 1. A fixing pipe 7 is fixedly installed inside the first paper tube 1 and on one side of the pump 6. The pump 6 is connected to the fixing pipe 7. Connecting pipes 8 are provided on both sides of the first paper tube 1 and on the side of the pump 6. The two connecting pipes 8 are inserted into the interior of the side plates 3 and the second paper tube 2 and fixedly connected to them. Multiple air outlets are provided on the two second paper tubes 2. Through holes that cooperate with the air outlets are provided on the two connecting pipes 8.

[0031] In this embodiment of the invention, the thin-film industrial paper tube with anti-winding structure uses a first paper tube 1 as the main supporting structure. Side plates 3 are respectively provided on opposite sides of the first paper tube 1. A second paper tube 2 is fixedly connected to the side of each side plate 3 closest to the first paper tube 1, and the second paper tube 2 is slidably engaged with the first paper tube 1, allowing it to extend and retract along the axial direction of the first paper tube 1. At the same time, the fixing block 4 on the inner side of the side plate 3 is inserted into the interior of the first paper tube 1 and slidably connected, forming an adjustable double-sided limiting structure.

[0032] When the film is wound, the pump 6 inside the first paper tube 1 is started, and the airflow is delivered to the connecting pipes 8 on both sides through the fixed pipe 7. Since the connecting pipe 8 is fixedly connected to the second paper tube 2, and both are respectively provided with matching through holes and air outlets, the airflow is finally discharged from the air outlet of the second paper tube 2, forming an air film at the contact point between the film and the second paper tube 2. This air film can reduce the frictional resistance during film winding, and at the same time, the airflow pressure helps the film to remain flat, thus initially achieving the anti-winding function.

[0033] In this embodiment of the invention, the sliding second paper tube 2 and the fixing block 4 can adapt to the winding requirements of films of different widths, thereby improving the versatility of the equipment; the air film support formed by the pump 6 and the air passage structure can reduce film wear, and at the same time, the airflow pressure is used to correct the winding position, effectively preventing winding deviation.

[0034] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -4. As a preferred embodiment of this utility model, a ventilation buffer layer 9 is fixedly installed inside the two second paper tubes 2 and inside the multiple air outlets. The two ends of the fixed tube 7 are respectively inserted into the interior of the two connecting tubes 8 and slidably connected thereto. A sealing ring is embedded in the end of the two connecting tubes 8 near the fixed tube 7.

[0035] The first paper tube 1 is rotatably connected to a bidirectional lead screw 5, which is inserted into the interior of two fixed blocks 4 and threadedly connected to them. A servo motor 10 is fixedly installed inside the first paper tube 1. Two gears 11 are rotatably connected inside the first paper tube 1. The two gears 11 mesh. The output end of the servo motor 10 is fixedly connected to one of the gears 11, and the other gear 11 is fixedly installed on the outside of the bidirectional lead screw 5.

[0036] A tapered guide ring 15 is fixedly installed on the side of each of the two side plates 3 that is far apart from each other. Multiple fixing bolts 14 are provided on the side of each of the two tapered guide rings 15 that is far apart from each other. The multiple fixing bolts 14 pass through the tapered guide ring 15 and are threaded to it. The multiple fixing bolts 14 are inserted into the interior of the side plate 3 and are threaded to it.

[0037] Electric telescopic rods 12 are fixedly installed on corresponding sides inside the first paper tube 1. T-blocks 13 are fixedly installed on the output ends of the two electric telescopic rods 12. The two T-blocks 13 are respectively inserted into the interior of the two fixed blocks 4 and slidably connected to them.

[0038] A control module 17 is fixedly installed inside the first paper tube 1. The control module 17 is electrically connected to the pump 6, the servo motor 10 and the two T-blocks 13. A rubber ring 16 is provided on the outside of the first paper tube 1. An annular groove that mates with multiple rubber rings 16 is opened on the first paper tube 1.

[0039] In this embodiment of the present invention, a ventilation buffer layer 9 is fixedly installed inside the air outlet of the second paper tube 2. It is made of porous elastic material. When the airflow enters the second paper tube 2 through the through hole of the connecting pipe 8, it needs to be dispersed and depressurized by the ventilation buffer layer 9 before being discharged from the air outlet. This avoids the airflow directly impacting the film and causing local wrinkles, making the air film pressure distribution more uniform.

[0040] The two ends of the fixed tube 7 are respectively inserted into the interior of the two connecting tubes 8, and the end of the connecting tube 8 closest to the fixed tube 7 is inlaid with a sealing ring. When the second paper tube 2 slides with the side plate 3, the connecting tube 8 and the fixed tube 7 slide relative to each other. The sealing ring can always maintain the airtightness of the connection between the two to prevent air leakage from affecting the air film effect.

[0041] When the spacing between the two side plates 3 needs to be adjusted according to the film width, the control module 17 starts the servo motor 10. The output end of the servo motor 10 drives the gear 11 connected to it to rotate. Through the meshing transmission of the two gears 11, the other gear 11 drives the bidirectional lead screw 5 to rotate synchronously. Since the bidirectional lead screw 5 is threadedly connected to the two fixed blocks 4 and the fixed blocks 4 are slidably connected to the first paper tube 1, the rotation of the bidirectional lead screw 5 will be converted into the opposite linear motion of the two fixed blocks 4, thereby driving the side plate 3 and the second paper tube 2 to move along the axial direction of the first paper tube 1 to achieve spacing adjustment.

[0042] A tapered guide ring 15 is fixedly installed on the side of the side plates 3 that is far apart from each other. Its cross-section is trumpet-shaped. The diameter of the end closer to the side plate 3 matches that of the side plate 3, and the diameter of the end farther away from the side plate 3 is slightly larger than the maximum width of the film. When the film enters the winding area, if there is a slight deviation, the inclined inner wall of the tapered guide ring 15 will guide the edge of the film and correct it to the correct winding position. The tapered guide ring 15 is fixedly connected to the side plate 3 by multiple fixing bolts 14. The bolts pass through the tapered guide ring 15 and are threaded to the side plate 3, which facilitates the disassembly and replacement of the tapered guide ring 15. Guide rings with different tapers can be replaced according to the film thickness to improve the adaptability of the equipment.

[0043] After the spacing of the side plates 3 is adjusted to the target position, the control module 17 starts the electric telescopic rod 12, and its output end pushes the T-block 13 into the interior of the fixed block 4. The sliding mating surface of the T-block 13 and the fixed block 4 adopts an anti-slip texture design. After insertion, the movement of the fixed block 4 can be restricted by mechanical locking to prevent the spacing of the side plates 3 from shifting due to vibration during the winding process. When the width needs to be adjusted again, the electric telescopic rod 12 retracts and drives the T-block 13 to be pulled out from the fixed block 4, releasing the locking state, and the servo motor 10 can be restarted for adjustment.

[0044] The control module 17 inside the first paper tube 1 serves as the core control unit, electrically connected to the pump 6, servo motor 10, and electric telescopic rod 12, and is remotely operated via an external controller. Operators can preset parameters such as film width and air film pressure using the external controller. The control module 17 automatically coordinates the operation of each component: for example, it drives the servo motor 10 to adjust the spacing based on the width parameter, adjusts the air film pressure via the pump 6, and then locks the electric telescopic rod 12 after adjustment, achieving fully automated control of the entire process.

[0045] Multiple rubber rings 16 are provided on the outer side of the first paper tube 1. The rubber rings 16 are embedded in the annular groove of the first paper tube 1. When the film starts to wind, the rubber rings 16 are in close contact with the inner ring of the film. Their high coefficient of friction can prevent relative sliding between the film and the first paper tube 1, ensuring uniform winding tension.

[0046] In this embodiment of the invention, the ventilated buffer layer 9 achieves a stable airflow output, further improving the flatness of the film winding; the sliding sealing structure ensures that the air path remains sealed during the adjustment process, ensuring stable air film pressure and enhancing the reliability of anti-winding deviation.

[0047] The gear 11 transmission, combined with the bidirectional lead screw 5, enables synchronous reverse movement of the two side plates 3, ensuring adjustment accuracy; the precise control of the servo motor 10 can meet the precise adaptation of different film widths, improving the automation level and adjustment efficiency of the equipment.

[0048] The tapered guide ring 15 can perform pre-correction in the early stage of film winding, reducing the working pressure of the subsequent anti-winding structure; the detachable design allows the guide ring to be flexibly adapted to different specifications of films, enhancing the versatility of the equipment.

[0049] The control module 17 enables the coordinated operation and automated control of various components, reducing the intensity of manual operation and improving winding accuracy; the rubber ring 16 enhances the friction between the film and the paper tube, avoids slippage and winding deviation, and protects the inner ring of the film from damage.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
