Description

Technical Field

[0001] This utility model relates to a transmission reel for transporting PVA film, belonging to the field of reel technology. Background Technology

[0002] During the production process, PVA membranes typically require the use of drive rollers for receiving, transferring, and rewinding to ensure stable operation of the membrane material on a continuous production line. Existing drive roller structures are mostly fixed in arrangement, making it difficult to flexibly adjust the roller spacing and position according to the membrane size. This leads to wrinkles, loosening, or misalignment of the PVA membrane during transportation, affecting the stability of subsequent processing and the quality of the finished product.

[0003] In addition, some existing equipment lacks an auxiliary support structure for the membrane material, making it difficult to keep the membrane material flat during transmission and causing it to easily shift, thereby reducing production efficiency. Therefore, there is an urgent need for a transmission reel structure that can adjust the reel state according to the PVA membrane size and has stable support and transmission functions to improve the adaptability and operational reliability of the production line. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and solve the problem that the transmission roller structure in the existing PVA film production line is mostly fixed and cannot be flexibly adjusted according to the size of the film material. This causes the PVA film to be prone to wrinkles, loosening or displacement during the transmission process, and lacks an effective support structure for bearing and stabilizing the film material, which in turn affects the flatness of the film material and the continuity of the production line.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: A drive reel for transporting PVA film is provided, comprising: Base; A fixed bracket is mounted on the base; a fixed roller is mounted on the fixed bracket. A movable scroll that is slidably connected to a fixed bracket; A reel drive mechanism connected to a movable reel is used to drive at least one movable reel to move up and down; It also includes: a receiving reel for receiving materials; one end of the receiving reel is provided with a fixing plate, and the fixing plate is connected to a fixing bracket; The receiving reel is connected to a main shaft at its center, and the receiving reel is rotatably connected to the main shaft.

[0006] Furthermore, at least one spindle is provided, and each spindle is provided with at least one receiving reel.

[0007] Furthermore, the spindle is configured as two, and one end of the two spindles is connected by a locking device.

[0008] Furthermore, the fixed bracket is a rectangular plate arranged in parallel, and one of the rectangular plates has a slot in the vertical direction. The movable scroll is slidably connected to the fixed bracket through the slot.

[0009] Furthermore, the reel drive mechanism includes: a U-shaped plate, two identical movable shafts, and a cylinder; the cylinder is mounted on the base surface and connected to the U-shaped plate, and both ends of the U-shaped plate are respectively connected to the movable shafts; the movable shafts are connected to the movable reel.

[0010] Furthermore, the side wall of the fixed bracket is provided with two meshing gears, which are coaxially connected to the fixed roller and the movable roller, respectively.

[0011] Furthermore, both the fixed reel and the receiving reel have an anti-slip layer on their surfaces.

[0012] Furthermore, a blocking element is provided at the top of the fixed bracket.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention achieves lifting and lowering adjustment of the movable roller by setting a fixed bracket and a fixed roller on a base, and slidingly connecting the movable roller to the fixed bracket and connecting the movable roller to a roller drive mechanism. Furthermore, by connecting the roller to the main shaft for rotation, the PVA film can remain stable during transmission and winding. This not only allows for flexible adjustment of the roller's working state according to the size of the PVA film and production process requirements, improving the device's adaptability to different specifications of PVA film, but also effectively improves the film material's receiving and transmission effect through the setting of the roller, avoiding slack and deviation of the film material during transmission, and ensuring the continuity and stability of the production process.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] In one specific embodiment, a drive reel for transporting PVA film is provided, such as... Figure 1 As shown, the system includes a base 1, on which a fixed support 2 is mounted. Specifically, the fixed support 2 is a rectangular plate 21 arranged in parallel. A fixed scroll 3 is mounted on the fixed support 2, and a movable scroll 4 is mounted on the other side of the fixed support 2 via a sliding connection. The movable scroll 4 is raised and lowered by a scroll drive mechanism 5.

[0019] like Figure 2 and Figure 3 As shown, the scroll drive mechanism 5 includes a cylinder 53, a U-shaped plate 51 and a movable rotating shaft 52. The cylinder 53 is fixed on the base 1 and its output end is connected to the U-shaped plate 51. Both ends of the U-shaped plate 51 are rotatably connected to the movable rotating shaft 52, which in turn drives the movable scroll 4 to rise and fall.

[0020] Specifically, when the PVA film passes through the fixed roller 3, the movable roller 4, driven by the cylinder 53, applies pressure to the PVA film, effectively reducing unevenness and wrinkles on the film surface and ensuring the stability of the transmission process. It is worth noting that the fixed roller 3 can also be replaced with a cutting component as needed to cut or trim the PVA film, enhancing the device's versatility.

[0021] like Figure 4As shown, a receiving reel 6 for materials is also provided on the base 1. A fixing plate 7 is fixed to one end of the receiving reel 6, and the fixing plate 7 is connected to the fixing bracket 2, thereby ensuring the stable installation of the receiving reel 6. A main shaft 61 is connected to the axis of the receiving reel 6, and the receiving reel 6 can rotate on the main shaft 61.

[0022] Specifically, multiple receiving rolls 6 can be provided on the main shaft 61, and these receiving rolls 6 are all coaxially arranged to realize the function of simultaneously winding multiple PVA films, thereby improving production efficiency. In order to adapt to different production processes, multiple main shafts 61 can be provided, of which the main shaft 61 located at the end is used for final winding, and the receiving rolls 6 on the remaining main shafts 61 are used for intermediate transfer and sorting of PVA film, thereby maintaining the tension of PVA film and ensuring that PVA film is always in optimal condition before entering the winding stage.

[0023] It should be noted that the driving component of the drive gear in this embodiment has been omitted, and a commonly used motor or rotation drive component can be used.

[0024] To ensure that the movable scroll 4 does not fall off during the lifting process, a blocking element 9 is provided at the top of the fixed bracket 2. When the cylinder 53 drives the U-shaped plate 51 to rise, the blocking element 9 can limit the U-shaped plate 51 and prevent it from falling out of the slot 22 on the fixed bracket 2, thereby ensuring the reliability of the overall operation.

[0025] In a further embodiment, the side wall of the fixed bracket 2 is provided with meshing gears 23, which are coaxially connected to the fixed roll 3 and the movable roll 4 respectively. The synchronous operation of the rolls can be achieved through the transmission of the gears 23, thereby improving the coordination of winding. The surfaces of the fixed roll 3 and the receiving roll 6 are also provided with anti-slip layers 8 to increase the friction between them and the PVA film, avoid slippage, and further ensure the stability of the film material during transportation and winding.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
