[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0028] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0029] As Figures 1 - 5 shown, the present utility model provides a rewinder for large-size film materials, including a base 1, a support plate 2 fixedly connected to the upper surface of the base 1, a reel 3 rotatably connected inside the support plate 2, a motor 4 fixedly connected to the upper surface of the base 1, a belt 5 sleeved on the output end of the motor 4, the belt 5 sleeved on the arc surface of the reel 3, a wrinkle removal structure 6 provided on the upper surface of the base 1, and an adjusting structure 7 provided on the side wall of the support plate 2.
[0030] Next, specifically describe the specific settings and functions of its wrinkle removal structure 6 and adjusting structure 7.
[0031] As Figure 2 and Figure 3As shown, the wrinkle-removing structure 6 includes a mounting plate 601. The mounting plate 601 is fixedly connected to the base 1. A strip-shaped hole 602 is formed on the surface of the mounting plate 601. A clamping plate 603 is slidably connected to the inner wall of the strip-shaped hole 602. A fixing block 604 is fixedly connected to the side wall of the mounting plate 601. A spring 605 is fixedly connected to the lower surface of the fixing block 604. The lower end of the spring 605 is fixedly connected to a ring 606. A rotating block 607 is rotatably connected to the surface of the ring 606. A threaded rod 608 is threadedly connected to the inner wall of the rotating block 607. The threaded rod 608 penetrates through the fixing block 604. The upper end of the threaded rod 608 abuts against the lower surface of the clamping plate 603. A limiting block 609 is fixedly connected to the lower end of the threaded rod 608. The limiting block 609 is slidably connected to the inner wall of the strip-shaped hole 602. The limiting block 609 serves to prevent the threaded rod 608 from rotating synchronously with the rotating block 607. A number of anti-slip grooves 610 are formed on the arc surface of the rotating block 607. The anti-slip grooves 610 serve to increase the friction force on the arc surface of the rotating block 607.
[0032] As Figure 4 and Figure 5 shown, the adjusting structure 7 includes two U-shaped plates 71. The U-shaped plates 71 are fixedly connected to the support plate 2. A rectangular plate 72 is slidably connected to the inner wall of the U-shaped plates 71. A roller 73 is rotatably connected to the side wall of the rectangular plate 72. The roller 73 is slidably connected to the belt 5. A bolt 74 is threadedly connected to the rectangular plate 72. One end of the bolt 74 is rotatably connected to a pressing plate 75. A number of convex blocks 76 are fixedly connected to the surface of the pressing plate 75. The convex blocks 76 serve to increase the friction force between the bolt 74 and the support plate 2. Two baffle plates 77 are fixedly connected to the surface of the U-shaped plates 71. The bolt 74 is located between the two baffle plates 77. The baffle plates 77 serve to limit the moving distance of the bolt 74 and prevent the rectangular plate 72 from sliding out of the U-shaped plates 71.
[0033] The overall working principle is as follows: when winding a large-sized film material, the reel is sleeved on the arc surface of the reel 3 and fixed. Then, the film material is passed through the upper surface of the clamping plate 603, and one end of the film material is wound on the arc surface of the reel. After that, the rotating block 607 is rotated. The rotating block 607 has a tendency to move downward by means of the thread. At this time, the limiting block 609 serves to prevent the threaded rod 608 from rotating synchronously with the rotating block 607, and the anti-slip groove 610 serves to increase the friction force on the arc surface of the rotating block 607. The movement of the rotating block 607 will pull the ring 606, and the movement of the ring 606 will stretch the spring 605. At the same time, the spring 605 will drive the ring 606 to move upward by means of its own elastic force. The movement of the rotating block 607 following the ring 606 will drive the threaded rod 608 to move, and the movement of the threaded rod 608 will jack up the clamping plate 603. The clamping plate 603 will press the film material against the surface of the mounting plate 601. At this time, continuously rotating the rotating block 607 can adjust the pressure of the clamping plate 603 on the film material, facilitating the removal of wrinkles from film materials with different tensile strengths. After that, the motor 4 is started. The rotation of the output end of the motor 4 will drive the belt 5, and the belt 5 will drive the reel 3 to rotate. The reel will follow the rotation of the reel 3 to wind the film material. During the movement of the film material, the cooperation between the clamping plate 603 and the mounting plate 601 can remove wrinkles from the film material, thereby preventing the occurrence of indentations on the surface of the rewound film material.
[0034] When it is necessary to adjust the tightness of the belt 5, the bolt 74 is rotated. The bolt 74 will drive the pressing plate 75 to move away from the support plate 2 by means of the thread. The movement of the pressing plate 75 will cause the convex block 76 to disengage from the support plate 2, and then the rectangular plate 72 is slid along the inner wall of the U-shaped plate 71. The sliding of the rectangular plate 72 will drive the roller 73 to slide, and the sliding of the roller 73 will tighten the belt 5, thus ensuring the normal operation of the belt 5. During this process, the baffle 77 serves to limit the moving distance of the bolt 74 and prevent the rectangular plate 72 from sliding out of the U-shaped plate 71. After that, the bolt 74 is rotated in the reverse direction. When the convex block 76 abuts against the surface of the support plate 2, the convex block 76 serves to increase the friction force between the bolt 74 and the support plate 2, and the bolt 74 serves to limit the position of the rectangular plate 72, thereby limiting the position of the roller 73.
[0035] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
