Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic laying technology, and in particular to an automatic laying device for fiber materials. Background Technology
[0002] Fiber materials are structured materials formed from fibrous substances through textile processing. They are also commonly referred to as textile materials, and their application history is quite long.
[0003] In the prior art, Chinese patent CN204977497U discloses a fiber filament laying head mechanism for an automated production device for composite material grids. This mechanism can simultaneously lay multiple sets of fiber filaments and produce arbitrary rectangular grids from multiple sets of fiber filaments. However, in practical applications, the automated carbon fiber laying device requires a robot to lay multiple layers of carbon fiber back and forth, necessitating frequent cutting of the carbon fiber according to the laying path. This causes the cutting blades of the carbon fiber to become damaged and require frequent replacement. Existing automated carbon fiber laying devices require the entire cutting blade assembly to be disassembled before the cutting blade can be replaced, resulting in cumbersome operation and time-consuming replacement. Therefore, we disclose an automated fiber material laying device. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose an automatic fiber material laying device to solve the problem that the cutting blade of the automatic laying device is not easy to replace.
[0005] To achieve the above objectives, this utility model provides an automatic fiber material laying device, including a fixed frame. Two cutting frames are disposed at the lower end of the fixed frame. Several cylinders are fixedly connected between the two cutting frames. The fixed frame is fixedly connected to one of the cutting frames. The two cutting frames are symmetrically distributed. A connecting groove is formed in the middle of each cutting frame. A blade holder is slidably connected within the connecting groove. A blade is fixedly connected to one end of the blade holder, extending through to the outside of the cutting frame. Several first moving grooves are formed at one end of each cutting frame. Several sets of moving frames are rotatably connected to one end of each cutting frame. The moving frames are movably connected within the first moving grooves. A connecting frame is rotatably connected to one end of each moving frame. The connecting frame is movably engaged with the blade holder. A spring is fixedly connected to the other end of each moving frame. The relative position of the two moving frames is limited by the spring.
[0006] Preferably, the connecting groove is a T-shaped groove, and limit grooves are provided on both sides of the tool holder, the limit grooves being movably engaged with the connecting frame.
[0007] Preferably, the movable frame includes an arc-shaped rod and a straight rod, the adjacent sections of the arc-shaped rod and the straight rod are fixedly connected, the arc-shaped rod is rotatably connected to the connecting frame, a connecting rod is fixedly connected between the straight rods of the movable frame located on the same side of the cutting frame, and the two ends of the spring piece are respectively fixedly connected to the connecting rods on both sides of the cutting frame.
[0008] Preferably, the other end of the cutting frame has two second moving slots, which are connected to the first moving slot. A second limiting block is slidably connected in the second moving slot. One end of the second limiting block is fixedly connected to the connecting frame. The other ends of the two second limiting blocks extending to the outside of the cutting frame are respectively fixedly connected to a first positioning block and a second positioning block. Both the first positioning block and the second positioning block are in contact with the blade.
[0009] Preferably, the sides of the first positioning block and the second positioning block are both right-angled triangles, and the two ends of the first positioning block are fixedly connected to the first limiting block, which is movably engaged with the second positioning block.
[0010] Preferably, the second moving groove is a T-shaped groove, and the second limiting block is a T-shaped frame.
[0011] Preferably, a plurality of positioning posts are fixedly connected to the middle of the first positioning block, and the positioning posts penetrate the blade and are movably engaged with the second positioning block.
[0012] The beneficial effects of this utility model are as follows: By connecting the fixed frame and the laying device, when cutting carbon fiber, the cylinder is activated to drive the two cutting frames to move in opposite directions to cut the carbon fiber. The cutting frame restricts the position of the blade holder and the blade through the connecting groove, so that the blade is limited by the cutting frame to cut the carbon fiber. When the operator squeezes the spring, the corresponding moving frame moves in the opposite direction, which in turn drives the connecting frame to move. Then the blade holder is pushed into the connecting groove to a limited position. Then the squeezing of the spring is released, so that the spring moves the moving frame and the connecting frame back to the original position, so that the connecting frame and the blade holder are engaged, restricting the position of the blade holder in the connecting groove. This effectively restricts the position of the blade holder and the blade, and the operation is simple and convenient, which facilitates the replacement of the blade and improves work efficiency.
[0013] The second moving slot restricts the movement of the second limiting block, so that when the connecting frame moves, it will drive the second limiting block to move together. When the second limiting block moves, it will drive the first positioning block and the second positioning block to move, so that the blade is fixed by the first positioning block and the second positioning block when working, making the blade position stable and not easy to break. It also prevents the blade from sticking to the first positioning block and the second positioning block when disassembling, which is conducive to the disassembly of the blade.

[0022] like Figures 1-3As shown, an automatic fiber material laying device includes a fixed frame 1. Two cutting frames 2 are arranged at the lower end of the fixed frame 1. Several cylinders 3 are fixedly connected between the two cutting frames 2. The fixed frame 1 is fixedly connected to one cutting frame 2, and the two cutting frames 2 are symmetrically distributed. A connecting groove 5 is opened in the middle of the cutting frame 2. A blade holder 6 is slidably connected within the connecting groove 5. A blade 7 is fixedly connected to one end of the blade holder 6, extending through to the outside of the cutting frame 2. Several first moving grooves 8 are opened at one end of the cutting frame 2. Several sets of moving frames 9 are rotatably connected to one end of the cutting frame 2, and the moving frames 9 are movably connected within the first moving grooves 8. A connecting frame 11 is rotatably connected to one end of the moving frame 9, and the connecting frame 11 is movably engaged with the blade holder 6. A spring is fixedly connected to the other end of each moving frame 9. 10. The relative positions of the two movable frames 9 are limited by the spring piece 10. The connecting groove 5 is a T-shaped groove. Limiting grooves are opened on both sides of the blade holder 6. The limiting grooves are movably engaged with the connecting frame 11. The movable frame 9 includes an arc-shaped rod and a straight rod. The adjacent sections of the arc-shaped rod and the straight rod are fixedly connected. The arc-shaped rod is rotatably connected to the connecting frame 11. A connecting rod is fixedly connected between the straight rods of the movable frames 9 located on the same side of the cutting frame 2. The two ends of the spring piece 10 are fixedly connected to the connecting rods on both sides of the cutting frame 2. In use, two cutting frames 2 are set at the lower end of the fixed frame 1. Several cylinders 3 are fixedly connected between the two cutting frames 2. The fixed frame 1 is fixedly connected to one cutting frame 2. The two cutting frames 2 are symmetrically distributed so that the fixed frame 1 is connected to the laying device. When cutting carbon fiber, the cylinders are activated. The cylinder 3 drives two cutting frames 2 to move towards each other to cut carbon fiber. A connecting groove 5 is provided in the middle of the cutting frame 2, within which a blade holder 6 is slidably connected. One end of the blade holder 6 is fixedly connected to a blade 7, which extends through the outside of the cutting frame 2. The cutting frame 2, through the connecting groove 5, restricts the position of the blade holder 6 and the blade 7, allowing the blade 7 to be limited by the cutting frame 2 to cut the carbon fiber. Several first moving grooves 8 are provided at one end of the cutting frame 2, and several sets of moving frames 9 are rotatably connected to one end of the cutting frame 2. The moving frames 9 are movably connected within the first moving grooves 8. One end of each moving frame 9 is rotatably connected to a connecting frame 11, which is movably engaged with the blade holder 6. The other end of each moving frame 9 is fixedly connected to a spring piece 10, allowing the operator to squeeze the spring piece 10. 0, causing the corresponding movable frame 9 to move in the opposite direction, which in turn causes the movable frame 9 to drive the connecting frame 11 to move. Then, the tool holder 6 is pushed into the limiting position in the connecting groove 5. Next, the pressure on the spring piece 10 is released, causing the spring piece 10 to drive the movable frame 9 and the connecting frame 11 back to their original positions, so that the connecting frame 11 engages with the tool holder 6, limiting the position of the tool holder 6 in the connecting groove 5. This effectively restricts the position of the tool holder 6 and the blade 7, and the operation is simple and convenient, facilitating the replacement of the blade 7 and improving work efficiency. The connecting groove 5 is a T-shaped groove, which can restrict the movement direction of the tool holder 6 and the blade 7. Limiting grooves are provided on both sides of the tool holder 6, and the limiting grooves are movably engaged with the connecting frame 11, so that the connecting frame 11 restricts the movement of the tool holder 6 through the limiting grooves.To ensure the stability of the blade holder 6 during operation, a movable frame 9, comprising an arc-shaped rod and straight rods, is used. Adjacent sections of the arc-shaped rod and straight rod are fixedly connected, and the arc-shaped rod is rotatably connected to a connecting frame 11. This allows the movable frame 9 to move, driving the connecting frame 11 to translate. Connecting rods are fixedly connected between the straight rods of the movable frames 9 located on the same side of the cutting frame 2. The two ends of the spring piece 10 are fixedly connected to the connecting rods on both sides of the cutting frame 2, allowing multiple movable frames 9 to be moved simultaneously for ease of operation.
[0023] As a preferred embodiment of this example, Figure 2 and Figure 3As shown, two second moving grooves 12 are provided at the other end of the cutting frame 2. The second moving grooves 12 are connected to the first moving groove 8. A second limiting block 13 is slidably connected in the second moving groove 12. One end of the second limiting block 13 is fixedly connected to the connecting frame 11. The other ends of the two second limiting blocks 13 extending to the outside of the cutting frame 2 are respectively fixedly connected to a first positioning block 14 and a second positioning block 16. Both the first positioning block 14 and the second positioning block 16 are in contact with the blade 7. The sides of the first positioning block 14 and the second positioning block 16 are both right-angled triangles. Both ends of the first positioning block 14 are fixedly connected to a first limiting block 4. The first limiting block 4 and the second positioning block 16 are movably engaged. The second moving groove 12 is a T-shaped groove. The two limiting blocks 13 are T-shaped frames. Several positioning posts 15 are fixedly connected to the middle of the first positioning block 14. The positioning posts 15 penetrate the blade 7 and are movably engaged with the second positioning block 16. Two second moving grooves 12 are opened at the other end of the cutting frame 2, communicating with the first moving groove 8. A second limiting block 13 is slidably connected within the second moving groove 12. One end of the second limiting block 13 is fixedly connected to the connecting frame 11, thus restricting the movement of the second limiting block 13 by the second moving groove 12. When the connecting frame 11 moves, it drives the second limiting block 13 to move together. The other ends of the two second limiting blocks 13 extending outside the cutting frame 2 are respectively fixedly connected to the first positioning block 14 and the second positioning block 16. 6. Both the first positioning block 14 and the second positioning block 16 are in contact with the blade 7, so that when the second limiting block 13 moves, it will drive the first positioning block 14 and the second positioning block 16 to move as well. This ensures that the blade 7 is fixed by the first positioning block 14 and the second positioning block 16 during operation, making the position of the blade 7 stable and less prone to breakage. It also prevents the blade 7 from contacting the first positioning block 14 and the second positioning block 16 during disassembly, facilitating the disassembly of the blade 7. Since the sides of the first positioning block 14 and the second positioning block 16 are both right-angled triangles, the first positioning block 14 and the second positioning block 16 have a good effect on restricting the position of the blade 7 and do not easily obstruct the operator's view. The first positioning block 14 is fixed at both ends. A first limiting block 4 is connected, which is movably engaged with a second positioning block 16, so that the positions of the first positioning block 14 and the second positioning block 16 after they are in contact with the blade 7 are relatively fixed, restricting the movement of the blade 7 to both ends and further reinforcing the stability of the blade 7. The second moving groove 12 is a T-shaped groove, and the second limiting block 13 is a T-shaped frame, so that the second moving groove 12 restricts the movement direction of the second limiting block 13. Several positioning posts 15 are fixedly connected to the middle of the first positioning block 14. The positioning posts 15 penetrate the blade 7 and are movably engaged with the second positioning block 16, so that the first positioning block 14 and the second positioning block 16 cooperate to effectively restrict the position of the blade 7 and ensure the stability of the blade 7 during operation.
