Description

Technical Field

[0001] This utility model relates to the technical field of film winding equipment, specifically a film winding equipment with anti-wrinkle function. Background Technology

[0002] Packaging films are made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins. They are widely used in the food, pharmaceutical, and chemical industries. After the plastic film is blown into shape, it needs to be wound up, which requires the use of winding equipment.

[0003] A search revealed a packaging film winding device (CN215516005U), comprising a PLC controller for overall control, a rotating platform, a support base plate mounted on the rotating platform, and two sets of winding mechanisms mounted opposite each other on the support base plate. Each winding mechanism includes a first bracket, guide rollers, a second bracket, a winding motor, a telescopic drive assembly, a rotary encoder, an active rotating shaft, and a driven rotating shaft. The two winding mechanisms are switched to ensure continuous winding operations, significantly enhancing practicality compared to existing winding devices. However, this structure ensuring continuous winding requires the support base plate to rotate 180°. Firstly, it requires ample space for the winding device installation to prevent obstruction of the support base plate's rotation. Secondly, it necessitates ensuring no workers are present during rotation to avoid injury. Therefore, the structure ensuring continuous winding has poor practicality, and deviations in the rotation angle can easily lead to wrinkles during film winding.

[0004] Based on this, a film winding device with anti-wrinkle function is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a film winding device with anti-wrinkle function includes a worktable 1. The top of the worktable 1 is respectively provided with a translation component, an adjustment mechanism 6, a first mounting plate 8 and a limiting mechanism 9. The outside of the translation component is provided with a winding mechanism 5.

[0027] The winding mechanism 5 includes a movable seat 501. A second mounting groove 502 is provided on one side of the top of the movable seat 501. A second lead screw 503 is rotatably mounted inside the second mounting groove 502. One end of the second lead screw 503 passes through the movable seat 501 and is connected to a knob 504. A movable plate 505 is threadedly connected to the outside of the second lead screw 503. A fixed plate 506 is fixedly mounted on the other side of the top of the movable seat 501. Rotary seats 507 are rotatably mounted on opposite sides of the movable plate 505 and the fixed plate 506. A second motor 508 is connected to the input end of the rotary seat 507. The second motor 508 is fixedly mounted to the fixed plate 506. A winding roller 509 is provided between the two rotary seats 507.

[0028] In this embodiment, the translation component can effectively drive the two winding mechanisms 5 to move together. When one winding mechanism 5 is winding, the other winding mechanism 5 is located at one end of the worktable 1. This facilitates the unwinding operation of the unwound winding mechanism 5, thereby greatly improving the winding efficiency. Different lengths of winding rollers 509 are used according to the winding requirements of different widths of film. When installing the winding roller 509, one end of the winding roller 509 is engaged with the rotating seat 507 connected to the second motor 508. Then, the knob 504 is rotated, which drives the second lead screw 503 to rotate. The rotation of the second lead screw 503 changes the position of the moving plate 505, so that the rotating seat 507 installed with the moving plate 505 is engaged with the other end of the winding roller 509. This structure is simple and easy to adjust and install according to the length of the winding roller 509. At the same time, it is convenient to disassemble the winding roller 509 after it has been wound up.

[0029] In one embodiment, such as Figure 1 As shown, the translation component includes a first mounting slot 2, which is located on the top of the worktable 1. A first lead screw 3 is rotatably mounted inside the first mounting slot 2. The input end of the first lead screw 3 is connected to a first motor 4, and the first motor 4 is fixedly mounted to the worktable 1. The moving seat 501 is threadedly connected to the first lead screw 3. The first motor 4 drives the first lead screw 3 to rotate, and the rotation of the first lead screw 3 effectively drives the two winding mechanisms 5 to move together.

[0030] In one embodiment, such as Figure 3 As shown, the adjustment mechanism 6 includes a fixed frame 601, which is symmetrically fixedly installed on the top of the workbench 1. A third mounting groove 602 is provided on one side of the fixed frame 601. A slider 603 is slidably mounted on one side of the fixed frame 601 through the third mounting groove 602. A third lead screw 604 is rotatably mounted inside the third mounting groove 602. The third lead screw 604 and the slider 603 are connected by a thread. A third motor 605 is connected to the input end of the third lead screw 604, and the third motor 605 is fixedly connected to the fixed frame 601. The slider 603 is rotatably mounted on one side with a first pressure roller 606. A third motor 605 drives a third lead screw 604 to rotate, which in turn moves the slider 603 up and down, thereby changing the height of the first pressure roller 606. When the film tension decreases, the first pressure roller 606 moves upward to effectively increase the tension. When the film tension is high, the first pressure roller 606 moves downward to reduce the film tension. This avoids film wrinkles due to insufficient tension and film deformation due to excessive tension, thus improving the quality of film winding.

[0031] In one embodiment, such as Figure 3 As shown, the top of the slider 603 is provided with an anti-wrinkle mechanism 7. The anti-wrinkle mechanism 7 effectively flattens the film, avoids wrinkles during film winding, and improves the quality of film winding.

[0032] In one embodiment, such as Figure 3 As shown, the anti-wrinkle mechanism 7 includes a mounting frame 701, which is fixedly mounted on the top of the slider 603. A threaded rod 702 with a threaded connection passes through the top of the mounting frame 701. A crank 703 is provided at the top of the threaded rod 702. A lifting frame 704 is rotatably mounted at the bottom of the threaded rod 702. A first limiting rod 705 is fixedly mounted at the top of the lifting frame 704, and the first limiting rod 705 is slidably mounted to the mounting frame 701. A second pressure roller 706 is rotatably mounted inside the lifting frame 704. By turning the crank 703, the threaded rod 702 is driven to rotate. The rotation of the threaded rod 702 drives the lifting frame 704 to move up and down, thereby changing the position of the second pressure roller 706. This allows the film to pass between the second pressure roller 706 and the first pressure roller 606, flattening the film. This structure is simple and easy to adjust according to the thickness of the film.

[0033] In one embodiment, such as Figure 1 As shown, a guide roller 10 is rotatably mounted on one side of the first mounting plate 8. The film passes under the guide roller 10, and the cooperation between the guide roller 10 and the adjustment mechanism 6 effectively adjusts the tension of the film.

[0034] In one embodiment, such as Figure 4 As shown, the limiting mechanism 9 includes a second mounting plate 901, which is symmetrically and fixedly mounted on the top of the workbench 1. A positive and negative screw 902 is rotatably mounted on the outer side of the second mounting plate 901. The input end of the positive and negative screw 902 is connected to a fourth motor 903, and the fourth motor 903 is fixedly mounted to the second mounting plate 901. The positive and negative screw 902 is symmetrically threaded with limiting plates 905. The operation of the fourth motor 903 drives the positive and negative screw 902 to rotate. The rotation of the positive and negative screw 902 drives the two limiting plates 905 to move together, which is convenient for adjustment according to the width of the film. This allows the two limiting plates 905 to fit against the two sides of the film, thus limiting the film and preventing it from shifting during the winding process.

[0035] In one embodiment, such as Figure 4 As shown, a second limiting rod 904 is fixedly installed on one side of the second mounting plate 901, and the second limiting rod 904 is located directly below the positive and negative screws 902. The limiting plate 905 and the second limiting rod 904 are slidably installed. The setting of the second limiting rod 904 improves the stability of the movement of the limiting plate 905, thereby improving the limiting effect.

[0036] The above embodiment discloses a film winding device with anti-wrinkle function. A first motor 4 drives a first lead screw 3 to rotate, which effectively moves two winding mechanisms 5 together. When one winding mechanism 5 is winding, the other winding mechanism 5 is located at one end of the worktable 1, facilitating the unwinding operation of the unwound winding mechanism 5, thus greatly improving winding efficiency. Different lengths of winding rollers 509 are used according to the winding requirements of films of different widths. When installing the winding rollers 509, one end of the winding roller 509 engages with the rotating seat 507 connected to the second motor 508. Then, rotating the knob 504 drives the second lead screw 503 to rotate, which in turn changes the position of the moving plate 505. The position of the rotating seat 507, which is mounted on the moving plate 505, engages with the other end of the take-up roller 509. The third motor 605 drives the third lead screw 604 to rotate, which in turn drives the slider 603 to move up and down, thereby changing the height of the first pressure roller 606. When the film tension decreases, the first pressure roller 606 moves upward to effectively increase the tension. When the film tension is high, the first pressure roller 606 moves downward to reduce the film tension. By turning the rocker handle 703, the threaded rod 702 is driven to rotate, which in turn drives the lifting frame 704 to move up and down, thereby changing the position of the second pressure roller 706. This allows the film to pass between the second pressure roller 706 and the first pressure roller 606, thus flattening the film.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
