Description

Technical Field

[0001] This utility model belongs to the technical field of hot pressing devices, and specifically relates to a hot pressing device for material composite. Background Technology

[0002] In the hot pressing process of composite materials (such as fiber-reinforced prepregs, multilayer films, etc.), in order to prevent the material surfaces from sticking together during hot pressing, it is usually necessary to set an isolation membrane between the composite material and the hot pressing equipment to play a role in isolation and protection.

[0003] Traditional hot-pressing equipment often produces release films that are only for single use. The release film unwound before hot pressing is discarded directly and cannot be recycled, resulting in material waste and increased costs. The unwinding process of the release film lacks effective tension control methods, and the unstable unwinding speed can easily lead to film surface loosening or stretching deformation, affecting the neatness of winding and the smooth progress of subsequent processes. To solve the above problems, we provide a hot-pressing device for material composite. Utility Model Content

Two U-shaped blocks are fixedly connected to one side of the hot pressing device. A first air shaft is provided between the two U-shaped blocks. Bearings are sleeved at both ends of the first air shaft. The interior of the U-shaped blocks is engaged with the bearings. A limit bolt is threaded to the top of the U-shaped blocks.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Example 1: refer to Figures 1-5 A hot pressing device for material composite includes a hot pressing device 1, a winding mechanism 2 installed on one side of the hot pressing device 1, an unwinding mechanism 3 installed on the other side of the hot pressing device 1, and a tension adjusting mechanism 4 installed on the top of the hot pressing device 1. The winding mechanism 2 includes a geared motor 21. The front of the hot pressing device 1 is bolted to the geared motor 21. The output end of the geared motor 21 is fixedly connected to a first gear 22. The front of the hot pressing device 1 is rotatably connected to a second gear 23. The surface of the first gear 22 meshes with the second gear 23 through its teeth. Two U-shaped blocks 24 are fixedly connected to one side of the hot pressing device 1. A first air shaft 25 is provided between the two U-shaped blocks 24. Both ends of the first air shaft 25 are fitted with bearings 26. The inside of the U-shaped blocks 24 is engaged with the bearings 26. The top of the U-shaped blocks 24 is threadedly connected to a limit bolt 27. One end of the first air shaft 25 is fixedly connected to a third gear 28. The surface of the third gear 28 meshes with the second gear 23 through its teeth. The unwinding mechanism 3 includes a second air expansion shaft 32. Two safety clamps 31 are bolted to one side of the hot pressing device 1. The inside of the safety clamps 31 is engaged with the second air expansion shaft 32. A magnetic powder brake 33 is bolted to one side of the hot pressing device 1. The output end of the magnetic powder brake 33 is fixedly connected to the rotating shaft of the safety clamps 31. The magnetic powder brake 33 is a mature existing technology. The unwinding tension is precisely controlled by the controller. Its working principle will not be described in detail here.

[0014] Specifically, the device uses a hot-pressing device 1 to hot-press the composite material. The bearing 26 is placed inside the U-shaped stop 24 and is abutted and limited by the limiting bolt 27 to ensure stable meshing between the third gear 28 and the second gear 23. The geared motor 21 drives the first gear 22 through the second gear 23 and the third gear 28 to drive the first air shaft 25 to rotate smoothly inside the bearing 26. It also works with the paper tube to wind up the release film, realizing the recycling and reuse of the release film of the composite material before hot pressing, effectively reducing production costs. After hot pressing, a second air shaft 32 is set on the side and another roll of release film is put on it to re-isolate and wind up the composite material after hot pressing, avoiding damage or adhesion to the material surface after hot pressing, further improving the quality of the finished product. The magnetic powder brake 33 can accurately control the unwinding speed of the release film, effectively preventing tension fluctuations caused by unwinding too fast or too slow, and ensuring the neatness of winding and process stability.

[0015] refer to Figure 5 The tension adjustment mechanism 4 includes a reducer 41, the bottom of which is fixedly connected to the hot pressing equipment 1. A bearing seat 42 is bolted to one side of the hot pressing equipment 1. Rotating frames 43 are sleeved inside the worm gear of the reducer 41 and the bearing seat 42. A connecting rod 44 is fixedly connected between the two rotating frames 43. An adjusting roller 45 is rotatably connected between the two rotating frames 43. A handwheel 46 is fixedly connected to one end of the worm gear of the reducer 41. The reducer 41 is fixed to the bottom of the hot pressing equipment 1 and supports the rotating frames 43 in conjunction with the bearing seat 42, so that the rotating frames 43, the connecting rod 44, and the adjusting roller 45 form a stable and reliable adjustment frame. Rotating the handwheel 46 drives the worm gear of the reducer 41, which drives the rotating frames 43 to rotate through the worm gear transmission, thereby causing the adjusting roller 45 to swing up and down, realizing stepless adjustment of the tension of the release film. At the same time, the self-locking characteristic of the worm gear can ensure that the tension is constant after adjustment, avoid loosening during operation, effectively improve the winding flatness and process control accuracy, and has a simple structure and is easy to operate.

[0016] refer to Figure 1 and Figure 2 One side of the hot pressing equipment 1 is rotatably connected to a flattening roller 5, and the other side of the hot pressing equipment 1 is rotatably connected to two guide rollers 6. By rotatably connecting the flattening roller 5 to the feeding side of the hot pressing equipment 1, the composite material before entering the hot pressing can be effectively flattened, eliminating wrinkles and curling on the material surface, ensuring that the material is heated evenly and tightly bonded during hot pressing. The two guide rollers 6 are rotatably connected to the discharging side of the hot pressing equipment 1, which can stably guide the composite material and the release film after hot pressing, ensuring that they are smoothly transported to the winding station along the set path.

[0017] refer to Figure 1A U-shaped plate 7 is provided on one side of the hot press equipment 1. Support plates 8 are fixedly connected to both ends of the U-shaped plate 7. The bottom of the support plates 8 is fixedly connected to the hot press equipment 1. The U-shaped plate 7 is securely installed on one side of the hot press equipment 1 by the support plates 8 fixed at both ends. Spare release film rolls can be placed inside the U-shaped plate 7, which makes it convenient for operators to replace and replenish the release film in a timely manner, avoid interrupting production due to the exhaustion of release film, and effectively improve the continuous operation time of the equipment.

[0018] Brief description of the usage process: The composite material is hot-pressed by the hot-pressing equipment 1. A paper tube is placed on the surface of the first air expansion shaft 25. The bearing 26 of the first air expansion shaft 25 is placed inside the U-shaped stop 24. The limit bolt 27 is turned to abut and limit the bearing 26, so that the third gear 28 meshes with the second gear 23. The release film for the composite material winding protection is wound onto the paper tube on the surface of the first air expansion shaft 25. The reduction motor 21 is started to drive the first gear 22 to rotate. The first gear 22 drives the first air expansion shaft 25 to rotate inside the bearing 26 through the transmission of the second gear 23 and the third gear 28. The release film of the composite material before hot pressing can be wound up and reused. At the same time, another roll of release film is placed on the surface of the second air expansion shaft 32, so that the release film can be wound up and protected again after hot pressing. The unwinding speed of the release film can be controlled by setting the magnetic powder brake 33.
