[0037] In order to solve the technical problems mentioned in the aforementioned background technology, the inventor innovatively designed the following technical solution, and the specific implementation solution of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a film winding assembly 10 provided in this embodiment, Figure 2 The edge provided by this embodiment Figure 1 As shown in the cross-sectional view at the AA section line, the film winding assembly 10 includes a film winding shaft 20 and a film separation reel 30. The film winding shaft 10 includes an expansion member 200, a reel body 210 and a film winding ring 220 sleeved on the reel body, wherein an air passage 2101 is provided in the reel body 210, and an accommodating space 230 for accommodating the expansion member is provided between the reel body 210 and the film winding ring 220, and the air passage 2101 is communicated with the expansion member 200.

[0039] In this embodiment, the expansion member 200 can be a long strip of airbag with an interface, which is used to be laid in the accommodating space 230. The airway 2101 is connected to the interface of the airbag. When the airbag is inflated, it can occupy the entire accommodating space 230.

[0040] The film material separation reel 30 is sleeved on the film material winding ring 220 , and adjacent film material separation reels 220 form a winding space for the wound film, and the film is wound through the winding space.

[0041] It is worth noting that the film material winding shaft 20 is made of metal, and the film material separation reel 30 can be made of metal, plastic or other synthetic materials.

[0042] For further information, please refer to Figure 2 The reel body 210 includes a first end and a second end opposite to each other, the air channel 2101 extends from the first end into the reel body 210, and the first end is used to connect to an air supply device; the reel body 210 also includes a channel 2102 connecting the air channel 2101 and the expansion member 200, wherein the channel 2102 is arranged close to the first end.

[0043] In this embodiment, the air channel 2101 extends from the first end of the reel body 210 along a straight line direction (the extension direction of the reel body 210) into the reel body 210. The air supply device may be an air pump, and the gas provided by the air supply device may be air, and the type of gas is not specifically limited in this embodiment; the channel 2102 is arranged near the first end of the reel body 210 in this embodiment, and the extension direction of the channel 2102 is perpendicular to the extension direction of the reel body 210, that is, the channel 2102 extends along the radial direction of the reel body 210.

[0044] It is worth noting that the air pressure provided by the air supply device directly affects the tension of the subsequent film material. Therefore, the tension of the film material can be adjusted by adjusting the air pressure. However, excessive tension can easily cause the film material to break, and insufficient tension may cause the film material to loosen. The tension is not limited in this embodiment, but an appropriate tension should be selected according to the actual situation to ensure the quality of the film material.

[0045] For further information, please refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of a film winding ring provided in this embodiment, Figure 4 The edge provided by this embodiment Figure 3The cross-sectional view is shown at the BB section line. The film material winding ring 220 includes an inner film material winding ring 2201, an outer film material winding ring 2202 and at least one elastic member 2203, wherein the inner film material winding ring 2201 and the outer film material winding ring 2202 are coaxially arranged; the inner film material winding ring 2201 is sleeved on the reel body 210. The elastic member 2203 is arranged between the inner film material winding ring 2201 and the outer film material winding ring 2202, and is used to connect the inner film material winding ring 2201 and the outer film material winding ring 2202.

[0046] In this embodiment, the elastic member 2203 may be a spring, and there may be multiple springs between the inner film material winding ring 2201 and the outer film material winding ring 2202 , with one end of the spring fixed to the inner film material winding ring 2201 and the other end fixed to the outer film material winding ring 2202 .

[0047] For further information, please refer to Figure 2 The accommodating space 230 further includes a friction member 240, and the friction member 240 is disposed at the inner film material winding ring 2201. The expansion member 200 is disposed in the accommodating space 230, and the expansion member 200 and the friction member 240 are disposed correspondingly.

[0048] In this embodiment, the friction member 240 may be in a long strip shape and directly contacts the inner film winding ring 2201 of the film winding ring 220. The type and shape of the friction member 240 are not specifically limited here, but the length and size of the friction member 240 must match the length and size of the film winding ring 220; and when the expansion member 200 is inflated, it can fully contact the friction member 240.

[0049] Furthermore, a plurality of accommodating spaces 230 are formed between the reel body 210 and the film winding ring 220 , and the plurality of accommodating spaces 230 are distributed at intervals around the reel body 210 ; at least one expansion member 200 and a friction member 240 corresponding to the expansion member 200 are placed in each of the accommodating spaces 230 .

[0050] For example, please refer to Figure 5 When four accommodating spaces 230 are formed between the reel body 210 and the film winding ring 220 , the four accommodating spaces 230 are distributed along the radial direction of the reel body 210 , so as to make the tension act evenly on the film winding ring 220 .

[0051] For further information, please refer to Figure 2 and Figure 6 , Figure 6A schematic diagram of a film material separation reel provided in this embodiment. The film material winding assembly 10 also includes at least one film material separation turntable 30; the film material separation turntable 30 includes a fixing ring 300 and a separation turntable 310 located on the fixing ring, and the film material separation turntable 30 is fixed to the outer film material winding ring 2201 through the through hole of the fixing ring 300.

[0052] In this embodiment, the fixing ring 300 can be fixed to the film material dividing turntable 30 by screws, and the inner diameter of the through hole of the fixing ring 300 is the same as the inner diameter of the film material winding shaft 20, ensuring that the film material dividing turntable 30 can be fixed to the film material winding shaft 20.

[0053] For further information, please refer to Figure 2 When there are multiple film material separation discs 30, the film material separation discs 30 are arranged on the reel body 210 at equal intervals. The distance between two adjacent film material separation discs 30 is 15 mm to 25 mm. For example, the distance between two adjacent film material separation discs 30 is 15 mm, 17 mm, 19 mm, 21 mm, 23 mm, 25 mm, etc.

[0054] Furthermore, the film material separation rotating disc 30 also includes a plurality of openings, and the openings 320 are arranged around the through hole of the fixing ring 300, and the openings 320 are centrally symmetrical about the center of the through hole. In this embodiment, since the interval between two adjacent film material separation reels is too small, the purpose of providing the openings 320 on the film material separation reel 30 is to facilitate the operator to install the film material to be rolled up on the film material winding shaft for winding, which not only improves the aesthetics of the material, but also brings convenience to the operator.

[0055] In addition, the size, number and position of the openings 320 are not specifically limited here, but need to be set according to actual conditions. For example, four openings are set on the film material separation turntable, and the specific shape is as follows: Figure 6 shown.

[0056] For further information, please refer to Figure 2 The film winding assembly 10 further includes a motor 40 , which is disposed at a first end of the reel body 210 ; the motor 40 is electrically connected to the reel body 210 for driving the reel body 210 to rotate.

[0057] In this embodiment, the motor 40 is disposed between the air supply device and the reel body 210 . The rotation direction of the reel body 210 driven by the motor 40 is not specifically limited here, but needs to be set according to actual conditions.

[0058] Based on the above description of the specific structure of the film material winding assembly, the working principle of the film material winding assembly 10 is introduced as follows: turn on the air supply device and the motor 40 switch, the motor 40 drives the film material winding shaft 20 to rotate, and the air supply device provides gas to the air duct 2101.

[0059] After the gas fills the air passage 2101, the gas enters the expansion member 200 in the accommodating space 230 through the passage 2102, and the volume of the expansion member 200 increases until it contacts the friction member 240. The friction member 240 is pushed outward by the expansion member 200 to move outward and press the inner film material winding ring 2201. As the friction between the friction member 240 and the inner film material winding ring 2201 increases, the friction is sufficient to push the inner film material winding ring 2201 to rotate.

[0060] One end of the elastic member 2203 is connected to the inner film material winding ring 2201, and the other end is connected to the outer film material winding ring 2202. The outer film material winding ring 2202 starts to rotate due to the inner film material winding ring 2201, and the elastic member 2203 is stretched. When stretched, the elastic member 2203 will try to return to the unstretched state, and the elastic member 2203 generates an outward force. The force is transmitted to the fixed ring 300 through the outer film material winding ring 2202 and acts on the film to be wound. The movement of the fixed ring 300 causes the film to be wound on the fixed ring 300 to be stretched, thereby generating winding tension. Multiple groups of film to be wound are separated and sleeved on the fixed ring 300 by the film material separation turntable 30, and the film material winding shaft 20 continues to rotate under the action of the motor 40 until the winding is completed. The above structure can not only realize the synchronous winding of multiple groups of film materials, but also effectively control the tension between the film materials, thereby improving the efficiency and quality of film material winding.

[0061] The present application also provides a winding device, which includes any one of the aforementioned film material winding assemblies. The winding device using the aforementioned film material winding assembly can control the tension of the film material winding and improve the quality of the film material winding.

[0062] It is worth noting that, in the present application, the membrane material includes but is not limited to a composite material unidirectional tape.

[0063] In summary, the film winding assembly and winding device provided in the embodiments of the present application, the film winding assembly includes a film winding shaft and a film separation reel. The film winding shaft includes an expansion member, a reel body and a film winding ring sleeved on the reel body, wherein an air passage is provided in the reel body, and a storage space for accommodating the expansion member is provided between the reel body and the film winding ring, and the air passage is connected to the storage space. The film separation reel is sleeved on the film winding ring, and adjacent film separation reels form a winding space that is the same as the winding film. In this way, the above structure can utilize air pressure regulation to control the tension of the film winding, and simultaneously realize the separation and winding of multiple groups of film materials, effectively improving the production efficiency and product yield of the release film.

[0064] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
