[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figures 1-3 The high-speed hot melt adhesive coating machine for composite tapes shown includes a frame 1, a rotating shaft 4, an adjusting mechanism, and a locking mechanism. A coating mechanism 2 is installed inside the frame 1. The coating mechanism 2 controls the coating thickness and uniformity. The coating mechanism 2 includes a coating system and a winding system. The coating system uniformly coats the liquid material onto the substrate surface through pressure transfer or slit extrusion, followed by drying to form a functional film layer. The winding system uses a winding wheel to automatically collect the substrate. The rotating shaft 4 is rotatably connected to the inner wall of the frame 1, and the shaft 4 is located away from the frame 1. A fixing block 5 is fixedly connected to one end, and a guide plate 3 is provided on the outer wall of the fixing block 5. An adjustment mechanism is provided outside the fixing block 5. The fixing block 5 is used to adjust the position of the guide plate 3. A locking mechanism is provided outside the guide plate 3. The locking mechanism is used to fix the guide plate 3. In specific use: the coating mechanism 2 is used to complete the coating work on the substrate. Multiple guide plates 3 form a guide roller. The tension of the guide roller can be adjusted by adjusting the multiple guide plates 3 to expand or tighten during the coating process, so as to avoid the substrate from being overstretched or loosened, which would cause the material to deform or wrinkle.
[0023] On one hand, multiple guide plates 3 are arranged in a circumferential array, forming a guide roller to guide the substrate. A first connecting rod 15 is rotatably connected to the outer wall of the fixed block 5. A second slider 17 is rotatably connected to the end of the first connecting rod 15 away from the fixed block 5. The guide plate 3 is slidably connected to the outer wall of the second slider 17. The adjustment mechanism includes a threaded rod 6, which is rotatably connected to the end of the fixed block 5 away from the rotating shaft 4. A moving block 18 is threadedly sleeved on the outer wall of the threaded rod 6. A second connecting rod 16 is rotatably connected to the outer wall of the moving block 18. The end of the second connecting rod 16 away from the moving block 18 is rotatably connected to the middle of the outer wall of the first connecting rod 15. In specific use, when the moving block 18 moves towards the square of the fixed block 5, the second connecting rod 16 squeezes the first connecting rod 15 to rotate. The first connecting rod 15 drives multiple second sliders 17 away from the central axis of the threaded rod 6.
[0024] On the other hand, a fixed plate 7 is rotatably connected to the outer wall of the threaded rod 6, and a first slider 13 is fixedly connected to one end of the guide plate 3 near the fixed plate 7. The first slider 13 is slidably connected to the inner wall of the fixed plate 7. In specific use, under the limitation of the first slider 13, the guide plate 3 can only move towards or away from the central axis of the threaded rod 6. When it is necessary to adjust the tension of the guide plate 3, the guide plate 3 will not cause the substrate to shift.
[0025] Additionally, the locking mechanism includes a limiting block 8, and a limiting groove 14 is formed on the outer wall of the fixing plate 7. Multiple limiting grooves 14 are arranged in a circumferential array. A rotating plate 12 is fixedly connected to the end of the threaded rod 6 away from the fixing block 5. The limiting block 8 is engaged with the inner wall of one of the limiting grooves 14. An elastic element, including a spring 9, is provided between the rotating plate 12 and the limiting block 8. A circular rod 10 is fixedly connected to the outer wall of the limiting block 8, and the rotating plate 12 is slidably sleeved on the outer wall of the circular rod 10. A pull rod 11 is fixedly connected to the outer wall of the circular rod 10. The spring 9 is fixedly connected between the limiting block 8 and the rotating plate 12. In practical use: When it is necessary to adjust the tension of the guide plate 3, the worker holds down the fixed plate 7 and pulls the pull rod 11. The pull rod 11 drives the limit block 8 to move through the circular rod 10, while squeezing the spring 9 until the limit block 8 and the limit groove 14 are no longer engaged. The worker then rotates the pull rod 11, which drives the threaded rod 6 to rotate through the rotating plate 12. The threaded rod 6 drives the guide plate 3 to move towards or away from the central axis of the threaded rod 6. After the guide plate 3 is adjusted, the pull rod 11 is released, and the spring 9 drives the limit block 8 to reset, so that the limit block 8 and the limit groove 14 are re-engaged.
[0026] In practice: When the tension of the guide plate 3 needs to be adjusted, the worker holds down the fixed plate 7 and pulls the pull rod 11. The pull rod 11 moves the limiting block 8 through the circular rod 10, while simultaneously squeezing the spring 9 until the limiting block 8 and the limiting groove 14 are no longer engaged. The worker then rotates the pull rod 11, which drives the threaded rod 6 to rotate through the rotating plate 12. When the moving block 18 moves towards the square shape of the fixed block 5, the second connecting rod 16 squeezes the first connecting rod 15 to rotate. The first connecting rod 15 drives multiple second sliders 17 away from the central axis of the threaded rod 6. Under the limit of the first slider 13, the guide plate 3 moves towards or away from the central axis of the threaded rod 6. After the guide plate 3 is adjusted, the pull rod 11 is released, and the spring 9 drives the limiting block 8 to reset, so that the limiting block 8 and the limiting groove 14 are re-engaged.
