Technical Field

[0001] The utility model belongs to the technical field of carbon fiber cutting, in particular to a carbon fiber layer cutting device. Background Art

[0002] The carbon fiber layer refers to the hierarchical structure composed of carbon fiber materials. Carbon fiber is a high-performance fiber material with excellent properties such as high strength, high modulus, high temperature resistance, corrosion resistance, wear resistance, and light weight. Therefore, it is widely used in aerospace, automobile manufacturing, sports equipment, construction and other fields.

[0003] The carbon fiber layer is usually stacked with multiple layers of carbon fiber cloth or carbon fiber composite materials, and a solid overall structure is formed through processes such as interlayer bonding and curing. This structure has excellent mechanical properties and durability, can withstand large loads and impacts, and also has low density and good thermal stability.

[0004] Carbon fiber is a composite material with extremely high strength and rigidity. However, due to the limitations of its forming process and its brittleness, carbon fiber is prone to problems such as fiber twisting during the process of being made into carbon fiber layers, resulting in wrinkles on the surface. Cutting the wrinkled carbon fiber layers will lead to reduced quality of the cut parts.

[0005] To this end, the utility model provides a carbon fiber layer cutting device. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 to Figure 2As shown, a carbon fiber layer cutting device described in an embodiment of the utility model comprises a cutting machine body 1; a pair of control boxes 11 are slidably connected on both sides of the cutting machine body 1; a connecting rail 12 is fixedly connected between the pair of control boxes 11; a cutting assembly 13 is slidably connected to the middle of the connecting rail 12; the side walls of the control box 11 close to each other are provided with connecting frames 14; a rotating rod 15 is rotatably connected between the connecting frames 14; a rolling roller 16 is fixedly connected to the middle of the rotating rod 15; the rolling roller 16 is arranged above the cutting machine body 1, and when working, the rolling roller 16 is arranged on the path of cutting the carbon fiber layer. 6. When the carbon fiber layer placed on the cutting machine body 1 is pushed toward the position of the cutting assembly 13, the surface of the carbon fiber layer will be smoothed by the rolling roller 16 when the carbon fiber layer passes directly under the rolling roller 16, so that the twisted wrinkled part is pressed down, making the carbon fiber layer smoother when cutting, reducing the problem of deviation in the cutting angle due to wrinkles in the carbon fiber layer, and improving the production quality of the carbon fiber layer. By connecting the rolling roller 16 and the control box 11, whether the carbon fiber layer is pushed for cutting or the cutting assembly 13 is driven for moving cutting, the carbon fiber layer can be smoothed.

[0024] like Figure 1 to Figure 2 As shown, the connecting frame 14 and the side wall of the control box 11 are rotatably connected; the side wall of the connecting frame 14 is provided with a slide groove 22; the slide groove 22 is T-shaped; a slider 23 is slidably connected inside the slide groove 22; the slider 23 and the slide groove 22 are also rotatably matched; the side wall of the control box 11 is fixedly connected to a fixing frame 2; the fixing frame 2 is fixedly connected to a cylinder 21; the output end of the cylinder 21 is hinged to the slider 23. When working, when cutting carbon fiber layers of different thicknesses, first start The switch of the air cylinder 21 is turned on, so that the air cylinder 21 lifts the connecting frame 14 upward, thereby moving the rolling roller 16 away from the surface of the cutting machine body 1. At this time, the end of the carbon fiber layer is moved below the rolling roller 16, and the air cylinder 21 is started again to pull the connecting frame 14 downward, thereby making the rolling roller 16 tightly fit against the surface of the carbon fiber layer, so that the rolling roller 16 can level the carbon fiber layer. The height of the rolling roller 16 can be adjusted by the air cylinder 21, so that it can adapt to the leveling work of carbon fiber layers of more sizes and thicknesses, thereby improving the adaptability of the device.

[0025] like Figures 1 to 3As shown, a support block 31 is fixedly connected to the top side wall of the connecting frame 14; a fan 3 is fixedly connected to one of the side walls of the control box 11; a first air duct 32 is fixedly connected between the support blocks 31; the first air duct 32 passes through the side wall of the support block 31 close to the fan 3; a second air duct 33 is fixedly connected to the side wall of the fan 3; the end of the second air duct 33 is fixedly connected to the end of the first air duct 32; the second air duct 33 is arranged as a hose; a plurality of nozzles 34 are fixedly connected to the middle of the first air duct 32; the nozzles 34 are arranged facing the top of the cutting machine body 1. When working, by turning on the switch of the fan 3, the fan 3 is used to transport wind to the inside of the second air duct 33 and the first air duct 32, and then the wind is blown to the surface of the carbon fiber layer through the plurality of nozzles 34 arranged on the first air duct 32, so as to clean up the processing impurities on the surface of the carbon fiber layer, reduce the corrosion of the impurities to the carbon fiber layer, and improve the production quality and safety of the carbon fiber layer.

[0026] like Figure 3 and Figure 4 As shown, a pair of elastic ropes 42 are fixedly connected to the inner wall of the nozzle 34; the end of the elastic rope 42 is fixedly connected to the buoyancy ball 4; a through hole 41 is opened in the middle of the buoyancy ball 4. During operation, when the carbon fiber layer to be cut is relatively wide, the output power of the fan 3 is increased, so that the wind pressure transmitted to the nozzle 34 through the first air duct 32 is larger, and the nozzle 34 located at the output end of the nozzle 34 is blown out, so that part of the wind force flows to both sides through the arc surface of the nozzle 34, thereby increasing the cleaning range. When the wind force is reduced, the buoyancy ball 4 is pulled back under the elastic action of the elastic rope 42, so that the wind force can only flow out through the through hole 41, thereby making the wind force more concentrated. Through the setting of the buoyancy ball 4, when cutting a smaller carbon fiber layer, the wind force can be more concentrated for cleaning, and when cutting a larger carbon fiber layer, the cleaning wind force can be more diffused, so as to achieve better adaptability and cleaning.

[0027] like Figure 3 and Figure 4 As shown, a pair of guide rods 5 are fixedly connected to the inner wall of the nozzle 34; a pair of grooves 51 are formed in the middle of the buoyancy ball 4; the guide rods 5 slide and fit inside the grooves 51. When working, the moving direction of the buoyancy ball 4 is guided by the guide rods 5, which can reduce the possibility of misalignment of the buoyancy ball 4, making it difficult to block the port of the nozzle 34, and causing wind leakage, thereby improving the stability of the buoyancy ball 4 when working.

[0028] like Figure 2 As shown, the inner wall of the slide groove 22 is fixedly connected with multiple groups of blocking brushes 6; the blocking brushes 6 are symmetrically arranged on the slide groove 22. When working, by arranging the blocking brushes 6 on the slide groove 22, it is possible to reduce the entry of foreign matter into the slide groove 22, thereby causing the movement of the slider 23 to be stuck, thereby improving the smoothness of the slider 23 when working.

[0029] Working principle: by arranging a rolling roller 16 on the cutting path of the carbon fiber layer, when the carbon fiber layer placed on the cutting machine body 1 is pushed to the position of the cutting component 13, the surface of the carbon fiber layer will be smoothed by the rolling roller 16 when the carbon fiber layer passes directly under the rolling roller 16, so that the twisted wrinkled part is pressed down, making the carbon fiber layer smoother when cutting, reducing the problem of deviation in the cutting angle caused by wrinkles when cutting the carbon fiber layer, and improving the production quality of the carbon fiber layer. By connecting the rolling roller 16 and the control box 11, whether pushing the carbon fiber layer for cutting or driving the cutting component 13 for moving cutting, it can have a smoothing effect on the carbon fiber layer.

[0030] When cutting carbon fiber layers of different thicknesses, first start the switch of the cylinder 21, so that the cylinder 21 lifts the connecting frame 14 upwards, thereby moving the rolling roller 16 away from the surface of the cutting machine body 1. At this time, the end of the carbon fiber layer is moved below the rolling roller 16, and then the cylinder 21 is started to pull the connecting frame 14 downwards, so that the rolling roller 16 fits tightly against the surface of the carbon fiber layer, so that the rolling roller 16 can level the carbon fiber layer. By adjusting the height of the rolling roller 16 through the cylinder 21, it can adapt to the leveling work of carbon fiber layers of more sizes and thicknesses, thereby improving the adaptability of the device.

[0031] By turning on the switch of the fan 3, the fan 3 is made to transport wind to the inside of the second air duct 33 and the first air duct 32, and then the wind is blown toward the surface of the carbon fiber layer through the multiple nozzles 34 arranged on the first air duct 32, so that the processing impurities on the surface of the carbon fiber layer can be cleaned up, the corrosion of the impurities to the carbon fiber layer is reduced, and the production quality and safety of the carbon fiber layer are improved.

[0032] When the carbon fiber layer to be cut is relatively wide, the output power of the fan 3 is increased so that the wind pressure transmitted to the nozzle 34 through the first air duct 32 is greater, and the nozzle 34 located at the output end of the nozzle 34 is blown out, so that part of the wind force flows to both sides through the curved surface of the nozzle 34, thereby increasing the cleaning range. When the wind force is reduced, the buoyancy ball 4 is pulled back under the elastic action of the elastic rope 42, so that the wind force can only flow out through the through hole 41, thereby making the wind force more concentrated. Through the setting of the buoyancy ball 4, when cutting a smaller carbon fiber layer, the wind force can be more concentrated for cleaning, and when cutting a larger carbon fiber layer, the cleaning wind force can be more diffused, so as to achieve better adaptability and cleaning.

[0033] By using the guide rod 5 to guide the moving direction of the buoyancy ball 4, the possibility of the buoyancy ball 4 being misaligned and making it difficult to block the port of the nozzle 34 and causing wind leakage can be reduced, thereby improving the stability of the buoyancy ball 4 when working.

[0034] By providing a blocking brush 6 on the slide groove 22 , it is possible to reduce the possibility of foreign matter entering the slide groove 22 , thereby causing the slider 23 to become stuck, thereby improving the smoothness of the slider 23 when working.
