Description
Technical Field
[0001] This utility model relates to the field of winding device technology, and in particular to an adjustable winding device for polyester film production. Background Technology
[0002] A winding device for polyester film production is a piece of equipment specifically designed for polyester film production lines. It aims to achieve efficient film winding, protect film quality, and has adjustable functions to accommodate different film specifications. The winding shaft, the core component of the winding device, is used to wind the polyester film into rolls. The winding shaft typically has an adjustable diameter to accommodate films of different lengths and thicknesses. The tension control system ensures that the film tension remains constant during winding, preventing damage or unevenness caused by excessive or insufficient tension. Common tension control methods include using pneumatic devices, servo motors, or torque sensors to adjust the film tension in real time.
[0003] In existing polyester film production winding devices, the tension control system mostly uses multiple individual rotating rods to form a height difference, which facilitates the winding of the subsequent winding device and prevents the polyester film from wrinkling during the winding process. However, the height difference formed by multiple individual rotating rods is relatively cumbersome to adjust and has poor adaptability. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable winding device for polyester film production.
[0005] This utility model is achieved by the following technical solution: an adjustable winding device for polyester film production, including a winding fixing seat, an adjustment component is provided inside the winding fixing seat, a limit component is provided outside the adjustment component, and a winding component is provided inside the winding fixing seat.
[0006] The adjusting assembly includes a T-shaped slide groove, which is formed at the top of the winding fixing seat. A T-shaped slider is slidably connected to the inner wall of the T-shaped slide groove. A threaded rod is threadedly connected to the inner wall of the T-shaped slider. The outer wall of the threaded rod is rotatably connected to the inner wall of the winding fixing seat. The right side of the threaded rod penetrates the inner wall of the winding fixing seat and extends therefrom. An operating knob is fixedly connected to the right side of the threaded rod. A connecting block is fixedly connected to the top of the T-shaped slider. A drive rack is fixedly connected to the surface of the connecting block. A drive gear is meshed with the outer wall of the drive rack. A rotating rod is fixedly connected to the back of the drive gear. The outer wall of the rotating rod is rotatably connected to the inner wall of the winding fixing seat. The end of the rotating rod away from the drive gear passes through the inner wall of the winding fixing seat. A connecting block two is fixedly connected to the end of the rotating rod away from the drive gear. A height adjustment rod is fixedly connected to the right side of the surface of the connecting block two, and a height adjustment rod two is fixedly connected to the left side of the surface of the connecting block two. A guide groove is opened at the end of the height adjustment rod away from the connecting block two. The outer wall of the height adjustment rod is slidably connected to the inner wall of the guide groove. The outer wall of the height adjustment rod two is slidably connected to the inner wall of the guide groove. A rotating roller is rotatably connected to the outer wall of the height adjustment rod.
[0007] As a further improvement to the above solution, two rotating rollers are provided, and the two rotating rollers are symmetrically arranged with the rotating rod as the center.
[0008] By rotating the operating knob, the threaded rod is rotated, causing the T-shaped slider to slide along the inner wall of the T-shaped groove and the surface of the threaded rod. This causes the T-shaped slider to drive the connecting block, which in turn drives the drive rack. The drive rack then meshes with the drive gear, which in turn drives the rotating rod to rotate. The rotating rod carries the second connecting block, which in turn drives the high / low adjustment rod and the second height adjustment rod to slide along the guide groove.
[0009] As a further improvement to the above solution, the limiting component includes a guide rod, the outer wall of which is slidably connected to the inner wall of the guide groove, a limiting disk is slidably connected to the outer wall of the guide rod, a second limiting disk is slidably connected to the outer wall of the end of the guide rod away from the guide groove, a second guide groove is provided at the end of the guide rod away from the guide groove, and the outer wall of the guide rod is slidably connected to the inner wall of the second guide groove.
[0010] As a further improvement to the above solution, two guide rods are provided, and the two guide rods are symmetrically arranged with the rotating rod as the center.
[0011] As a further improvement to the above solution, a T-shaped groove is provided on the surface of the limiting disk, and a T-shaped slider is slidably connected to the inner wall of the T-shaped groove. A connecting block is fixedly connected to the bottom of the T-shaped slider. A bidirectional threaded rod is threadedly connected to the inner wall of the connecting block. The outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the winding fixing seat. The end of the bidirectional threaded rod near the drive gear passes through the inner wall of the winding fixing seat and extends therefrom. An operating rod is fixedly connected to the outer wall of the bidirectional threaded rod. A connecting bearing is rotatably connected to the inner wall of the limiting disk, and the inner wall of the connecting bearing is slidably connected to the outer wall of the rotating roller.
[0012] As a further improvement to the above solution, there are two T-shaped sliders, two connecting blocks, and four connecting bearings, which are symmetrically arranged around the rotating rod.
[0013] As a further improvement to the above solution, the winding assembly includes a drive motor, a rotating rod II fixedly connected to the output end of the drive motor, a limiting groove being formed at the end of the rotating rod II away from the drive motor, a winding rod being slidably connected to the inner wall of the limiting groove, an avoidance groove being formed on the surface of the winding fixing seat, the outer wall of the winding rod being slidably connected to the inner wall of the avoidance groove, a limiting slide groove being formed at the top of the winding fixing seat, a limiting plate being slidably connected to the inner wall of the limiting slide groove, and the outer wall of the limiting plate being slidably connected to the surface of the winding rod.
[0014] Through the above technical solution, rotating the operating lever rotates the bidirectional threaded rod, causing the symmetrically arranged connecting block three to drive the symmetrically arranged T-shaped slider two to slide inward along the surface of the bidirectional threaded rod simultaneously. This causes the T-shaped slider two to drive the limiting disk two and the limiting disk, while the limiting disk two and the limiting disk drive the connecting bearing to slide along the surface of the rotating roller.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a rotary knob to rotate a threaded rod, causing a T-shaped slider to slide along the inner wall of the T-shaped groove and the surface of the threaded rod. This causes the T-shaped slider to drive a connecting block, which in turn drives a drive rack. The drive rack meshes with a drive gear, which in turn drives a rotating rod to rotate. The rotating rod carries a second connecting block, which in turn drives two height adjustment rods to slide along a guide groove. This creates a height difference between the two height adjustment rods. Simultaneously, the height adjustment rods and the second height adjustment rod drive a rotating roller to slide, allowing the polyester film to slide between the height differences of the height adjustment rods and the second height adjustment rod. This facilitates height adjustment and adapts to the tensile strength and collection quality of the polyester film.
[0017] This invention utilizes a rotating operating lever to rotate a bidirectional threaded rod. This causes the symmetrically arranged connecting block three to simultaneously slide the symmetrically arranged T-shaped slider two inwards along the surface of the bidirectional threaded rod. The T-shaped slider two then drives the limiting disc two and the limiting plate, which in turn drive the connecting bearing to slide along the surface of the rotating roller. Simultaneously, the limiting disc two and the limiting plate slide and limit along the surface of the guide rod, thereby expanding the applicability of polyester film winding and enabling the winding of polyester films of different widths.

[0039] The implementation principle of an adjustable polyester film production winding device in this application embodiment is as follows: Rotating the operating knob 204 rotates the threaded rod 203, causing the T-shaped slider 202 to slide along the inner wall of the T-shaped groove 201 and the surface of the threaded rod 203. This causes the T-shaped slider 202 to drive the connecting block 205, which in turn drives the drive rack 206. The drive rack 206 then meshes with the drive gear 207, causing the drive gear 207 to drive the rotating rod 208 to rotate. The rotating rod 208 carries the second connecting block 209, which in turn drives the height adjustment rod 210 and the second height adjustment rod 211 along the guide groove. 212 slides, thus creating a height difference between the height adjustment rod 210 and the second height adjustment rod 211. Simultaneously, the height adjustment rods 210 and 211 drive the rotating roller 213 to slide, allowing the polyester film to slide between the height difference of the height adjustment rods 210 and 211. This facilitates adjustment of the height difference, adapting to the tension and collection quality of the polyester film. By rotating the operating rod 309, the operating rod 309 rotates the bidirectional threaded rod 308, causing the symmetrically arranged connecting block 307 to drive the symmetrically arranged T-shaped slider 306 to slide inwards along the surface of the bidirectional threaded rod 308. 306 drives the second limiting plate 303 and the second limiting plate 302. Simultaneously, the second limiting plate 303 and the second limiting plate 302 drive the connecting bearing 310 to slide along the surface of the rotating roller 213. At the same time, the second limiting plate 303 and the second limiting plate 302 slide and limit along the surface of the guide rod 301, thereby expanding the applicability of polyester film winding. It can limit and wind polyester films of different widths. While the height adjustment rod 210 and the second height adjustment rod 211 drive the rotating roller 213 to slide, the rotating roller 213 drives the limiting plate 302 and the second limiting plate 303 to slide, simultaneously driving the guide rod 301 along the guide groove 212 and the second guide groove 213. 304 slides, and then the connecting block 307 drives the T-shaped slider 306 to slide along the T-shaped groove 305, ensuring the connection relationship of the bidirectional threaded rod 308. Then, by running the drive motor 401, the output end of the drive motor 401 rotates the rotating rod 402. The rotating rod 402 rotates the winding rod 404 through the limiting groove 403. The winding rod 404 rotates along the inner wall of the clearance groove 407. At the same time, the end of the winding rod 404 away from the limiting groove 403 is limited by the limiting plate 406 inside the limiting groove 405, preventing the winding rod 404 from leaving the limiting groove 403, thereby improving the stability of the winding rod 404 during the winding process.
