Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, specifically to a traction device for long fiber composite materials. Background Technology

[0002] Composite materials are a process of manufacturing high-performance structural components by laminating reinforcing materials (such as long fibers and carbon fibers) with matrix resins (such as epoxy and polyester) and then using processes such as hot pressing, curing, and traction molding. The core of this process is to solve the problems of interlayer bonding strength, traction tension stability, and thickness adaptability, ultimately achieving continuous and efficient production of lightweight, high-strength components, which are widely used in aerospace, rail transportation, and new energy fields.

[0003] The above-mentioned technical conditions still have shortcomings: the existing traction equipment for long fiber composite materials cannot easily adjust the gap between each set of traction rollers, and therefore cannot be well applied to the traction of composite materials of different thicknesses.

[0004] Based on this, the present invention designs a traction device for long fiber composite materials to solve the above problems. Utility Model Content

[0009] By adopting the above technical solution, the height of the tension roller can be dynamically adjusted by the hydraulic telescopic rod, and the discharge tension can be precisely controlled to avoid material loosening.

[0010] Preferably, the drive seat has a driven wheel rotatably mounted inside, which is connected to the end of the drive roller. A drive motor is fixedly connected to one side of the outer frame. A transmission shaft is fixedly connected to the output shaft of the drive motor. Three sets of worm gears are fixedly connected to the transmission shaft. A turbine is meshed on each of the three sets of worm gears. A drive rod is coaxially fixed on the turbine. A drive wheel is fixedly connected to both ends of the drive rod. The drive wheel and the driven wheel are connected by a belt drive.

[0011] By adopting the above technical solution, the worm gear transmission achieves synchronous rotation of multiple drive rollers, uniform distribution of traction force, and eliminates the risk of slippage.

[0012] Preferably, all of the drive wheels are rotatably disposed inside the outer frame.

[0013] By adopting the above technical solutions, transmission stability is ensured and equipment misalignment failures are reduced.

[0014] Preferably, a dust collection mechanism is provided on the top inner side of the outer frame, with the absorption end of the dust collection mechanism close to the drive roller.

[0015] By adopting the above technical solution, the dust collection mechanism removes dust from the surface of the drive roller in real time, maintaining a clean production environment.

[0016] Preferably, the outer frame is also provided with multiple sets of protective nets.

[0017] By adopting the above technical solutions, the protective net isolates external interference and improves operational safety.

[0018] Preferably, inspection doors are provided on both bottom sides of the outer frame.

[0019] By adopting the above technical solutions, the double-sided inspection doors simplify the maintenance process and reduce downtime.

[0020] In summary, this application has the following beneficial technical effects: the adjustable pressure roller mechanism adapts to different material thicknesses, the multi-roller synchronous drive ensures uniform distribution of traction force, the dynamic tension control system avoids material deformation and breakage, and combined with automated dust removal and maintenance design, it significantly improves production efficiency and product yield while reducing equipment failure rate.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] A traction device for long fiber composite materials includes an outer frame 1. A discharge mechanism 2 is provided on one side of the outer frame 1. Multiple sets of drive seats 3 are provided inside the outer frame 1, and drive rollers 10 are positioned between two sets of drive seats 3. A pressure roller mechanism 5 is also provided inside the outer frame 1. Two sets of support plates 6 are fixedly connected to the other side of the outer frame 1, and a feeding guide roller 7 is rotatably positioned between the two sets of support plates 6. The pressure roller mechanism 5 includes multiple sets of mounting columns 51 fixed to the outer frame 1. Fixed seats 52 are fixedly connected to the top of two sets of mounting columns 51, and pushing cylinders 53 are fixedly connected to the top of the fixed seats 52. Corresponding two pushing cylinders... The air delivery cylinders 53 are controlled by the same controller, so that the pushing cylinders 53 located on both sides of the same upper pressure roller 56 can be controlled synchronously, thereby enabling the height of the upper pressure roller 56 to be stably adjusted. A movable plate 54 is fixedly connected to the telescopic shaft of the pushing cylinder 53, and a rotating seat 55 is fixedly connected to the bottom of the movable plate 54. The upper pressure roller 56 is rotatably arranged between the two sets of rotating seats 55. The long fiber composite material that needs to be pulled enters from the feed guide roller 7, then passes between the upper pressure roller 56 and the drive roller 10, and finally exits through the discharge mechanism 2, which can effectively guide the long fiber material.

[0027] Furthermore, the discharge mechanism 2 includes positioning plates 21 fixed on both sides of the outer frame 1, and discharge guide rollers 22 rotatably connected between the two sets of positioning plates 21. Hydraulic telescopic rods 23 are fixedly connected to the inner side of the two sets of positioning plates 21. The two sets of hydraulic telescopic rods 23 are controlled by the same hydraulic conveying mechanism so that they can move synchronously. Lifting seats 24 are fixedly connected to the extension and retraction ends of the two sets of hydraulic telescopic rods 23. Tensioning rollers 25 are rotatably connected between the two sets of lifting seats 24. This mechanism can effectively discharge long fiber composite materials, thereby facilitating subsequent processing.

[0028] Furthermore, a driven wheel 11 is rotatably arranged inside the drive base 3. The driven wheel 11 is connected to the end of the drive roller 10. A drive motor 12 is fixedly connected to one side of the inner frame 1. A transmission shaft 13 is fixedly connected to the output shaft of the drive motor 12. Three sets of worm gears 14 are fixedly connected to the transmission shaft 13. A turbine 15 meshes with each of the three sets of worm gears 14. A drive rod 16 is coaxially fixed to the turbine 15. A drive wheel 17 is fixedly connected to both ends of the drive rod 16. The drive wheel 17 and the driven wheel 11 are connected by belt drive. The drive motor 12 can drive the three sets of drive rollers 10 to rotate simultaneously, thereby providing power for the traction of long fibers and improving the traction effect.

[0029] Furthermore, multiple drive wheels 17 are rotatably disposed inside the outer frame 1, enabling them to rotate stably.

[0030] Furthermore, a dust collection mechanism 4 is provided on the top inner side of the outer frame 1. The dust collection mechanism 4 is based on the same principle as a common vacuum cleaner, only differing in arrangement and shape. The absorption end of the dust collection mechanism 4 is close to the drive roller 10, and can absorb the debris and dust attached to the drive roller 10.

[0031] Furthermore, multiple sets of protective nets 9 are installed on the outer frame 1 to protect the equipment and prevent it from affecting the operators.

[0032] Furthermore, inspection doors 8 are provided on both sides of the bottom of the outer frame 1, which can quickly maintain the equipment when an abnormality occurs.

[0033] The implementation principle of this embodiment is as follows: long fiber material enters the equipment through the feeding guide roller 7, and the drive motor 12 drives the drive rod 16 to rotate through the worm gear 14 and the turbine 15, so that the drive wheel 17 drives the drive roller 10 synchronously through the belt-driven driven wheel 11; the push cylinder 53 of the pressure roller mechanism 5 pushes the movable plate 54 to adjust the height of the upper pressure roller 56 to match the material thickness; the hydraulic telescopic rod 23 of the discharge mechanism 2 controls the height of the tension roller 25 to balance the tension; the dust collection mechanism 4 removes debris from the surface of the drive roller 10 in real time.
