Description

Technical Field

[0001] This utility model relates to the field of filament laying machine technology, and more specifically, to an adjustment device for filament bundles in an automatic filament laying machine. Background Technology

[0002] Prepreg tape breakage is a common problem during the operation of automatic filament placement machines. If a broken prepreg tape is not addressed promptly, it will continue to be laid on the die, leading to a decline in product quality. Furthermore, frequent machine shutdowns to repair broken prepreg tape not only affect production efficiency but also increase the workload of workers. Therefore, effectively solving the problem of prepreg tape breakage is crucial for improving the efficiency and product quality of automatic filament placement machines.

[0003] However, the existing automatic filament laying machine's filament adjustment device generally relies on manual periodic inspection and handling of broken prepreg tape, or on the installation of sensors to detect prepreg tape breakage and then automatically stop the machine for handling. However, both methods have their limitations. Manual inspection requires a lot of manpower and time, and it is difficult to achieve real-time monitoring. While automatic shutdown can achieve automation, it will affect production efficiency. Utility Model Content

[0018] Preferably, at least two support rods are fixedly connected to the connecting frame, and at least two circular through holes are provided on the separating plate. The separating plate is sleeved on the support rods through the circular through holes, and the separating plate can move horizontally on the support rods.

[0019] Preferably, the rolling mechanism includes:

[0020] The second electric telescopic rod is fixedly connected to the bottom of the connecting frame, and the moving end of the second electric telescopic rod is fixedly connected to a support plate;

[0021] A pressure roller, on which a first rotating shaft is fixedly connected, and the end of the first rotating shaft is rotatably connected to a support plate;

[0022] A movable roller, the end of which is provided with a slider, the slider being slidably connected to the side wall of the support plate in a vertical manner;

[0023] The third electric telescopic rod is fixedly connected to the connecting frame.

[0029] Preferably, a take-up roller is rotatably connected to the side wall of the support plate, and the take-up roller is located on one side of the cutting blade;

[0030] A drive motor is fixedly connected to the support plate, and the output shaft of the drive motor passes through the support plate and is fixedly connected to the end of the take-up roller.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In this utility model, the push plate is pushed downward by the first electric telescopic rod. When the side wall of the push plate contacts the side wall of the corresponding separation plate of the broken prepreg tape, the driver is turned off and the first servo motor is restarted. The output shaft of the first servo motor drives the lead screw to rotate, and the lead screw drives the first electric telescopic rod to move horizontally again. Thus, the separation plate pushes the broken prepreg tape and the prepreg tape winding reel and guide roller connected to it toward the first fixed rod and the second fixed rod. When the push plate pushes the prepreg tape winding reel and guide roller onto the first fixed rod and the second fixed rod respectively, the prepreg tape winding reel and guide roller connected to the broken prepreg tape cannot rotate, thus preventing the broken prepreg tape from being laid. This achieves the temporary removal of the broken prepreg tape, avoiding the need to lay it further, and also avoids shutting down the entire automatic filament laying machine, providing convenience for the staff.

[0034] 2. In this utility model, air is drawn into the protective cover through the air inlet hose by a fan. Simultaneously, since the cutter removes the prepreg tape, the removed portion is located on the cutter. Therefore, when the fan draws air into the protective cover through the air inlet hose, it also draws the removed end of the prepreg tape from the cutter into the protective cover through the air inlet hose. During operation, the output shaft of the drive motor drives the take-up roller to rotate. When the removed prepreg tape comes into contact with the take-up roller, the rotation of the take-up roller facilitates the wrapping of the prepreg tape onto it. This not only removes the broken prepreg tape, eliminating the need for workers to use tools to handle it, saving manpower and time, but also allows for the winding of the removed prepreg tape, preventing it from continuing to adhere to the mold.

A circular block is fixedly connected to the end of the first rotating rod 3 near the first fixed rod 4. The circular block is inserted into the circular groove and can rotate in the circular groove, so that the first fixed rod 4 can support the end of the first rotating rod 3. The diameter of the outer ring wall of the first fixed rod 4 is the same as the diameter of the outer ring wall of the first rotating rod 3, so that the prepreg winding reel 5 can move back and forth between the first fixed rod 4 and the first rotating rod 3.

[0051] The second fixed rod 39 is fixedly connected to the other side wall of the connecting frame 1. The end of the second rotating rod 6 is rotatably connected to the end of the second fixed rod 39.

The ends of the separating plates 8 are located between the circular baffles 38 on the two adjacent guide rollers 7, which facilitates the separating plates 8 to push the guide rollers 7 and the prepreg winding reels 5 to one side, thereby facilitating the adjustment of the amount of prepreg according to the requirements.

[0053] At least two strip-shaped grooves 9 are provided on the first rotating rod 3, the first fixed rod 4, the second rotating rod 6, and the second fixed rod 39.

The top of the connecting frame 1 has two strip-shaped grooves. The top of the moving block 13 and the first electric telescopic rod 14 are both fixedly connected to the sliding blocks, which are slidably connected in the strip-shaped grooves. The moving block 13 is fixedly connected to the nut, which is threadedly connected to the lead screw 12. During the rotation of the lead screw 12, the moving block 13 is driven to move horizontally by the thread restriction, thereby facilitating the horizontal movement of the first electric telescopic rod 14.

[0057] At least two support rods 16 are fixedly connected to the connecting frame 1, and at least two circular through holes 17 are provided on the separating plate 8. The separating plate 8 is sleeved on the support rods 16 through the circular through holes 17, and the separating plate 8 can move horizontally on the support rods 16.

The lower end of the push rod 25 is fixedly connected to the slider 23. The push rod 25 is used to push the slider 23 to move up and down. The support plate 19 is fixedly connected to the stress sensor 41. The stress sensor 41 is used to sense the stress of the prepreg tape. The stress sensor 41 is connected to the third electric telescopic rod 24, the first electric telescopic rod 14, and the first servo motor 11 through a signal, so as to facilitate the adjustment of the stress of the prepreg tape according to the requirements.

[0062] The support plate 19 is an inverted U-shape, and the two ends of the first rotating shaft 21 are rotatably connected to the side wall of the support plate 19.

[0063] A vertically arranged groove 26 is provided on the side wall of the support plate 19. The slider 23 is slidably connected in the groove 26, and a rectangular through hole is provided at the top of the groove 26. The lower end of the push rod 25 passes through the rectangular through hole and is fixedly connected to the slider 23.

[0064] A second rotating shaft 27 is fixedly connected to the moving roller 22, and the end of the second rotating shaft 27 is rotatably connected to the slider 23.

[0065] A rotating shaft 28 is rotatably connected to the side wall of the support plate 19, and a rotating plate 29 is fixedly connected to the rotating shaft 28. A cutting blade 30 is horizontally fixedly connected to the lower end face of the rotating plate 29, and the height of the rotating plate 29 is greater than the height of the support plate 19.

[0066] A second servo motor 31 is fixedly connected to the side wall of the support plate 19. The output shaft of the second servo motor 31 passes through the side wall of the support plate 19 and is fixedly connected to the rotating shaft 28.

[0067] A take-up roller 32 is rotatably connected to the side wall of the support plate 19, and the take-up roller 32 is located on one side of the cutter 30.

[0068] A drive motor 33 is fixedly connected to the support plate 19. The output shaft of the drive motor 33 passes through the support plate 19 and is fixedly connected to the end of the take-up roller 32.

[0069] A protective cover 34 is fitted on the outer side of the take-up roller 32. A fan 35 is installed inside the protective cover 34. An air inlet hose 36 is fixedly connected to the side wall of the protective cover 34. The air inlet hose 36 is fixedly connected to the rotating plate 29, and the lower end of the air inlet hose 36 is engaged with the cutting blade 30.

[0070] Working principle: Multiple prepreg tape winding reels 5, each containing prepreg tape, are fitted onto the first rotating rod 3. The prepreg tape winding reels 5 and the separating plates 8 are staggered, meaning the prepreg tape winding reels 5 are distributed between two adjacent separating plates 8. The connecting frame 1 is then bolted onto an existing automatic filament laying machine. The prepreg tape on the prepreg tape winding reels 5 passes through the guide roller 7 and is conveyed downwards by the guide roller 7. The guide roller 7 has a guide plate 40 on its side, which is fixedly connected to the connecting frame 1 at an incline. The lower end of the guide plate 40 extends to the upper end of the rotating plate 29 and cooperates with the rotating plate 29. During the downward conveying of the prepreg tape by the guide roller 7, the prepreg tape moves downwards along the inclined surface of the guide plate 40 and moves downwards to one side of the pressure roller 20, thereby facilitating the pressure roller 20 to crush the prepreg tape and make it easier for the prepreg tape to adhere to the mold surface.

[0071] When the stress sensor 41 on the support plate 19 detects that the stress of the prepreg tape is low, the stress sensor 41 transmits the information to the third electric telescopic rod 24. The third electric telescopic rod 24 pushes the push rod 25 downward, and pushes the slider 23 and the moving roller 22 downward through the push rod 25, so that the moving roller 22 contacts the prepreg tape downward and presses the prepreg tape downward, thereby increasing the stress of the prepreg tape. This facilitates the increase of the bonding strength of the prepreg tape and avoids the formation of gaps or air bubbles between layers of the prepreg tape during the laying process due to low stress.

[0072] When stress sensor 41 detects a breakage in one of the prepreg tapes, it transmits a signal to the first servo motor 11. The output shaft of the first servo motor 11 drives the lead screw 12 to rotate. The lead screw 12, through the threaded limit, drives the moving block 13 and the first electric telescopic rod 14 to move horizontally. When the first electric telescopic rod 14 moves to the side of the prepreg tape winding disc 5 and guide roller 7 corresponding to the broken prepreg tape, it is activated. The first electric telescopic rod 14 pushes the push plate 15 downward. When the side wall of the push plate 15 contacts the side wall of the separation plate 8 corresponding to the broken prepreg tape, the driver 2 is turned off, and the first servo motor 11 is restarted. The output shaft of the first servo motor 11 drives the lead screw. When screw 12 rotates, it drives the first electric telescopic rod 14 to move horizontally again. This pushes the broken prepreg tape, along with the prepreg tape winding reel 5 and guide roller 7 connected to it, towards the first fixed rod 4 and the second fixed rod 39 via the separation plate 8. When the push plate 15 pushes the prepreg tape winding reel 5 and guide roller 7 onto the first fixed rod 4 and the second fixed rod 39 respectively, the prepreg tape winding reel 5 and guide roller 7 connected to the broken prepreg tape cannot rotate. This prevents the broken prepreg tape from being laid out, thus temporarily removing the broken prepreg tape and avoiding further laying. It also prevents the entire automatic yarn laying machine from being shut down, providing convenience for the staff.

[0073] The prepreg tape that has not broken continues to be laid. After all the prepreg tapes in the same group have been laid, since the upper and lower layers of prepreg tape are laid alternately, the connecting frame 1 is driven to rotate by the automatic filament placement machine, so that the cutting blade 30 is parallel to the prepreg tape that has broken after laying. That is, the travel direction of the cutting blade 30 is parallel to the prepreg tape that has been laid. The second servo motor 31 is started, and the output shaft of the second servo motor 31 drives the rotating plate 29 to rotate. The lower end of the rotating plate 29 drives the cutting blade 30 to rotate downward. When the cutting blade 30 is located under the pressure roller 20, the automatic filament placement machine is started. The automatic filament placement machine drives the connecting frame 1 to move horizontally, thereby removing the broken prepreg tape by the cutting blade 30. The movement direction of the cutting blade 30 is parallel to the prepreg tape laid below the broken prepreg tape, thus avoiding cutting. The blade 30 removes the prepreg tape laid on the lower layer. During the process of the cutting blade 30 removing the broken prepreg tape, the fan 35 and drive motor 33 are started. The fan 35 draws air into the protective cover 34 through the air inlet hose 36. At the same time, since the part of the prepreg tape removed by the cutting blade 30 is located on the cutting blade 30, when the fan 35 draws air into the protective cover 34 through the air inlet hose 36, it will also draw the end of the prepreg tape removed by the cutting blade 30 into the protective cover 34 through the air inlet hose 36. During the operation of the drive motor 33, the output shaft of the drive motor 33 drives the take-up roller 32 to rotate. When the removed prepreg tape comes into contact with the take-up roller 32, the rotation of the take-up roller 32 makes it easier for the prepreg tape to wrap around the take-up roller 32, thereby realizing the winding of the removed prepreg tape.

[0074] When laying the prepreg tape again, firstly, the first electric telescopic rod 14 is activated, which drives the push plate 15 upward, causing it to disengage from the separating plate 8. Then, the first servo motor 11 is activated, which drives the first electric telescopic rod 14 away from the first rotating rod 3 via the lead screw 12, and closer to the side of the prepreg tape winding reel 5 and guide roller 7. The first electric telescopic rod 14 is activated again, pushing the push plate 15 downward. When the side wall of the push plate 15 contacts the side wall of the separating plate 8, the first servo motor 11 is activated. The output shaft of 11 drives the lead screw 12 to rotate in the opposite direction, thereby causing the push plate 15 to push the separation plate 8, the prepreg winding disc 5 on the first fixed rod 4, and the guide roller 7 on the second fixed rod 39 towards the first rotating rod 3 and the second rotating rod 6. When the prepreg winding disc 5 on the first fixed rod 4 moves to the first rotating rod 3, the driver 2 drives the first rotating rod 3 to rotate, and the first rotating rod 3 drives the prepreg winding disc 5 to rotate, thereby continuing to lay out the prepreg tape. This avoids the need to replace the laid prepreg tape mold when the prepreg tape breaks, saving time and avoiding waste of resources.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
