Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding mechanism for light-shielding tape. Background Technology

[0002] In the production and slitting process of light-blocking tape, winding is a key step to ensure the final product's shape and quality.

[0003] Traditional winding equipment often has a fixed winding shaft position, making it difficult to dynamically adjust the tension. During winding, the linear speed and tension of the tape vary greatly, which can easily lead to high tension at the beginning and slack at the end, resulting in defects such as wrinkles and breakage. In addition, the height of the pressure roller or guide roller of some winding equipment is often fixed, which cannot apply pressure flexibly. This may result in insufficient clamping force to effectively remove air, or excessive pressure to damage and deform the tape surface, affecting the final winding quality. In order to solve the above problems, this utility model provides a light-shielding tape winding mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a light-shielding tape winding mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A light-shielding tape winding mechanism includes a base plate. A first mounting groove is formed at the middle of the upper surface of the base plate. A first threaded screw is rotatably connected to the inside of the first mounting groove via a bearing. A movable seat is threaded onto the surface of the first threaded screw. A movable plate is fixedly connected to the upper end of the movable seat. A mounting frame is fixedly connected to one side of the upper surface of the movable plate. A turntable is rotatably connected to the upper end of one side of the mounting frame via a bearing. An air shaft is fixedly connected to one side of the turntable. A connecting assembly is fixedly connected to the front of the base plate. A power assembly is fixedly connected to the upper surface of the base plate.

[0006] As a further improvement of this utility model, the connecting assembly includes a U-shaped frame fixedly connected to the front of the base plate. A second mounting groove is provided on one side of the interior of the U-shaped frame. A second threaded screw is rotatably connected to the interior of the second mounting groove through a bearing. A lifting block is threaded onto the surface of the second threaded screw. A first connecting plate is fixedly connected to one side of the lifting block.

[0007] As a further improvement of this utility model, a third mounting groove is provided on the other side of the U-shaped frame. A limiting rod is fixedly connected inside the third mounting groove. A limiting ring is sleeved on the surface of the limiting rod. A second connecting plate is fixedly connected to one side of the limiting ring. A rolling shaft is rotatably connected between the first connecting plate and the second connecting plate through a bearing.

[0008] As a further improvement of this utility model, the power assembly includes a servo motor fixedly connected to the upper surface of the base plate, an active synchronous pulley fixedly connected to the power end of the servo motor, a driven synchronous pulley provided at the upper end of the other side of the mounting bracket, a synchronous belt sleeved between the active synchronous pulley and the driven synchronous pulley, and the driven synchronous pulley connected to the turntable.

[0009] As a further improvement of this utility model, the upper surface of the base plate is provided with sliding grooves on both sides, and the lower surface of the movable plate is fixedly connected with pulleys that are adapted to the sliding grooves on both sides.

[0010] As a further improvement of this utility model, an adjustment motor is fixedly installed on the back of the base plate. The power end of the adjustment motor is connected to the first threaded screw through a coupling. A handle is provided on one side of the upper surface of the U-shaped frame, and the handle is connected to the second threaded screw.

[0011] The beneficial effects of this utility model are: By setting up a movable plate, the adjustment motor drives the first threaded screw during use, which can precisely control the overall position of the movable plate and the mounting frame. This allows for flexible adjustment of the air shaft position, enabling the winding mechanism to dynamically adjust the tension of the tape during operation. This effectively adapts to tension changes caused by the increase in winding diameter. At the same time, the pulleys and grooves at the bottom of the movable plate cooperate to ensure smooth and stable movement, avoiding problems such as tape loosening, wrinkling, or breakage caused by unstable tension in traditional mechanisms, thus improving the quality and consistency of winding.

[0012] By setting up the connecting components, during use, turning the handle drives the second threaded screw, which in turn moves the lifting block and the first connecting plate up and down, thereby conveniently adjusting the height of the rolling shaft. This allows the tape to be effectively flattened and guided before winding, eliminating air gaps and unevenness on the sides that may occur during winding, ensuring a tight and neat roll shape. At the same time, the cooperation between the limiting rod and the limiting ring provides stable guidance for the lifting process, preventing the rolling shaft from shifting under pressure and enhancing the rigidity of the entire system.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 A light-shielding tape winding mechanism includes a base plate 1. A first mounting groove is formed at the middle of the upper surface of the base plate 1. A first threaded screw 2 is rotatably connected to the inside of the first mounting groove via a bearing. A movable seat 3 is threaded onto the surface of the first threaded screw 2. A movable plate 4 is fixedly connected to the upper end of the movable seat 3. A mounting bracket 5 is fixedly connected to one side of the upper surface of the movable plate 4. A turntable 6 is rotatably connected to the upper end of one side of the mounting bracket 5 via a bearing. An air shaft 7 is fixedly connected to one side of the turntable 6. A connecting assembly is fixedly connected to the front of the base plate 1. A power assembly is fixedly connected to the upper surface of the base plate 1.

[0019] In this utility model, the connecting component includes a U-shaped frame 8 fixedly connected to the front of the base plate 1. A second mounting groove is provided on one side inside the U-shaped frame 8. A second threaded screw 9 is rotatably connected inside the second mounting groove through a bearing. A lifting block 10 is threadedly sleeved on the surface of the second threaded screw 9. A first connecting plate 11 is fixedly connected to one side of the lifting block 10. The internal thread of the lifting block 10 is tightly engaged with the external thread of the second threaded screw 9. When the second threaded screw 9 rotates, the lifting block 10 can move up and down smoothly along the direction of the thread to achieve precise lifting adjustment.

[0020] A third mounting groove is provided on the other side of the U-shaped frame 8. A limiting rod 12 is fixedly connected inside the third mounting groove. A limiting ring 13 is sleeved on the surface of the limiting rod 12. The inner diameter of the limiting ring 13 is adapted to the outer diameter of the limiting rod 12, and it can slide freely on the limiting rod 12, thereby ensuring the stability of the rolling shaft 15 during the adjustment process. A second connecting plate 14 is fixedly connected to one side of the limiting ring 13. The rolling shaft 15 is rotatably connected between the first connecting plate 11 and the second connecting plate 14 through a bearing. The use of the bearing allows the rolling shaft 15 to rotate flexibly between the first connecting plate 11 and the second connecting plate 14, reducing friction with the tape, and ensuring that the tape can pass smoothly through the rolling shaft 15 during the winding process, achieving a stable pressing and guiding effect.

[0021] The power assembly includes a servo motor 16 fixedly connected to the upper surface of the base plate 1. The servo motor 16 provides reliable power support for the entire winding mechanism, ensuring the stability and accuracy of the winding process. The power end of the servo motor 16 is fixedly connected to an active synchronous pulley 17. A driven synchronous pulley 18 is provided at the upper end of the other side of the mounting bracket 5. A synchronous belt 19 is sleeved between the active synchronous pulley 17 and the driven synchronous pulley 18. The driven synchronous pulley 18 is connected to the turntable 6. The driven synchronous pulley 18 is tightly connected to the turntable 6 through a key connection, which can transmit its own rotational power to the turntable 6, causing the turntable 6 to drive the air shaft 7 to rotate, thus completing the tape winding work.

[0022] The upper surface of the base plate 1 has grooves 20 on both sides, and the lower surface of the movable plate 4 has pulleys 21 that are adapted to the grooves 20 on both sides. The pulleys 21 can roll flexibly in the grooves 20 as the movable plate 4 moves, making the movement of the movable plate 4 more stable and smooth, and reducing jamming and shaking.

[0023] An adjusting motor 22 is fixedly installed on the back of the base plate 1. The power end of the adjusting motor 22 is connected to the first threaded screw 2 via a coupling. The adjusting motor 22 can provide stable power for the movement of the movable plate 4, and realize precise adjustment of the winding tension. A handle 23 is provided on one side of the upper surface of the U-shaped frame 8. The handle 23 is connected to the second threaded screw 9. The handle 23 can accurately transmit the manual rotation power of the operator to the second threaded screw 9, so that the second threaded screw 9 can rotate according to the operation requirements to complete the task of adjusting the height of the rolling shaft 15.

[0024] In use, the adjusting motor 22 is first started, driving the first threaded screw 2 to rotate, which in turn moves the movable seat 3 and the movable plate 4, thereby adjusting the position of the mounting frame 5 and the air shaft 7. This allows the movable plate 4 to move and adjust the tension to adapt to changes during the winding process. The servo motor 16 operates, driving the turntable 6 and the air shaft 7 to rotate for winding via the active synchronous pulley 17, the synchronous belt 19, and the driven synchronous pulley 18. The tape passes around the rolling shaft 15 in the connecting assembly and then wraps around the paper roller of the air shaft 7. By rotating the handle 23, the second threaded screw 9 is rotated, causing the lifting block 10 and the first connecting plate 11 to move up and down, thereby changing the height of the rolling shaft 15. By adjusting the height of the rolling shaft 15, pressure can be applied to the tape to ensure that the tape is wound flat and tightly.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
