Description

Technical Field

[0001] The utility model relates to the technical field of composite material molding, in particular to a device for controlling swing balance tension and a hydrogen storage winding system. Background Art

[0002] A carbon fiber-wrapped metal-liner composite high-pressure hydrogen storage vessel is a composite of metal and non-metallic materials. Its structure consists of a metal liner wrapped with various fibers that are then cured to form a reinforced structure. To further reduce the weight of the high-pressure hydrogen storage vessel, increase the system's hydrogen storage density, and reduce costs, the metal liner is replaced with a plastic liner. The remaining structure and manufacturing process are essentially the same as those of a metal-lined composite pressure vessel, resulting in a fully composite plastic high-pressure hydrogen storage vessel. The fiber-wound layer can be made of carbon fiber, aramid fiber, or glass fiber.

[0003] Specifically, in the hydrogen storage container molding process, the molding of fully wound composite material hydrogen storage containers belongs to the field of composite material molding technology. The product is formed by the winding process and then enters the curing furnace for curing and molding into the final product. The winding process of hydrogen storage containers is divided into two types according to the difference in the form of raw materials used: wet winding process and dry winding process. The raw material used in the wet winding process is carbon fiber tow. The tow is first fully impregnated with resin in the impregnation device, and then directly wound onto the core mold through the wire nozzle under tension control. The raw material used in the dry winding process is prepreg yarn or prepreg narrow tape. The prepreg yarn or prepreg narrow tape is softened to a viscous state by heating the resin on the winding machine, and then wound onto the core mold.

[0004] In existing technology, yarn tension can fluctuate during the winding process due to various factors, potentially rendering the finished product unsatisfactory. Therefore, a tension balancing device is required to maintain yarn tension within a specified range during yarn winding to ensure that the finished product meets design strength requirements.

[0040] Example 1

[0041] Please refer to Figure 1-Figure 4This embodiment provides a device for controlling swing balance tension, comprising: a mounting member 8, an angle sensor 4 disposed on the mounting member 8, and an air shaft 7. The mounting member 8 serves as a mounting carrier for components; the mounting member 8 is preferably a mounting plate. The angle sensor 4 is disposed on a first side of the mounting member 8; a swing arm 1 is disposed on the angle sensor 4, and the angle sensor 4 is used to measure the angle of the swing arm 1. A driven roller 2 is disposed on the swing arm 1, wherein the driven roller 2 can form a rotational engagement with the mounting member 8. The driven roller 2 itself may also be provided with a rotatable portion to reduce the friction of the material wound around the driven roller 2. The driven roller 2 is preferably configured such that the first end of the driven roller 2 is disposed on the swing arm 1 and the second end extends toward the first side of the mounting member 8. The air shaft 7 is disposed on the first side of the mounting member 8 and is located lateral to the swing arm 1. The air shaft 7 is used to secure the coil and control the tension of the coil during unwinding or rewinding, wherein the coil is secured by being sleeved over the air shaft 7.

[0042] The following describes the operation of the present device for controlling swing-balanced tension, using a carbon fiber coil 6 and yarn as an example. During the yarn winding process (referring to the yarn being wound around a core mold, which is a metal or plastic liner), various factors can cause the yarn tension to fluctuate. This tension fluctuation can cause the swing arm 1 to swing, resulting in unqualified wound workpieces. In the technical solution for this device for controlling swing-balanced tension, an angle sensor 4 is connected to the rear of the swing arm 1. This angle sensor 4 measures the angle change and then feeds it back to the pneumatic shaft 7, controlling the output torque of the pneumatic shaft 7 to maintain yarn tension balance.

[0043] like Figure 1 In the illustrated embodiment, the first end of the pneumatic shaft 7 is connected to a reduction motor 3, which is mounted on the second side of the mounting member 8. This motor drives the pneumatic shaft 7 based on an electrical signal indicating the angle of the swing arm 1 to adjust the tension during unwinding or rewinding of the web. Specifically, changes in yarn tension drive the swing arm 1 to rotate. Angle sensor 4 measures this change in angle and feeds it back to the motor, which then adjusts its output torque to maintain yarn tension balance.

[0044] like Figure 4In one embodiment shown, the driven roller 2 adopts the following structure. The first end of the central shaft 16 is provided on the mounting member 8, and the second end extends toward the first side of the mounting member 8. The bearing 14 is sleeved on the central shaft 16. The first end of the roller 13 is sleeved on the bearing 14, and the second end extends toward the first side of the mounting member 8; the second end of the roller 13 preferably protrudes from the second end of the central shaft 16, that is, the roller 13 is longer than the central shaft 16, and the central shaft 16 is used to extend the roller 13. The structure of the driven roller 2 can be optimized as follows: two bearings 14 are provided, and a spacer sleeve 15 is provided outside the central shaft 16 between the two bearings 14, and the spacer sleeve 15 is used to limit the two bearings 14; a retaining spring 11 is provided on the central shaft 16 for limiting the inner bearing 14, and an end cover 12 is provided at the protruding end of the central shaft 16 for limiting the outer bearing 14. Two bearings 14 simultaneously penetrate the first end of the roller 13 to lift the roller 13. At this time, the lifted portion of the roller 13 is thickened, and the protruding portion of the roller 13 is thin-walled, making the roller 13 more stable and lighter. The roller 13 is long and can pass multiple yarns along its circumference.

[0045] like Figure 1 In one embodiment shown, driven rollers 2 are provided at both ends of the swing arm 1, and an angle sensor 4 is connected between the two ends of the swing arm 1. Specifically, the driven roller 2 includes a first driven roller and a second driven roller; the first end of the swing arm 1 is provided with a first driven roller, and the second end is provided with a second driven roller. The angle sensor 4 is connected between the two ends of the swing arm 1. Preferably, the air shaft 7 and the coil are provided on the side of the first driven roller, and the material of the coil is sequentially wound around the first driven shaft and the second driven shaft to form a Z shape. The Z-shaped arrangement can suppress the degree of swinging of the swing arm 1 to a certain extent. The yarn is wound in a Z-shape, the winding method is simple, and the overall structure is simple, and the tension of the yarn can be quickly adjusted.

[0046] In one embodiment, the inflatable shaft 7 includes: a reel, a key bar and an airbag. The key bar is provided on the wall of the reel; the key bar is provided in multiple pieces. The airbag is provided inside the reel and along the length direction of the reel; the airbag is used to push out the key bar when inflated. The inflatable shaft 7 is a special winding and unwinding shaft, which is a prior art. Its working principle is to use high-pressure inflation to make the key bar on the surface of the reel protrude, thereby achieving locking and fixing of the inner core of the coil. When it is necessary to lock the coil, it is only necessary to inflate the air nozzle of the inflatable shaft 7, and the key bar on the surface of the reel will extend and clamp the coil; when relaxing, the key bar will return to its original state by deflating, and the coil can be easily removed.

[0047] like Figure 1In one embodiment shown, the device for controlling the swing balance tension includes a swing limiter for limiting the swing range of the swing arm 1. The first end of the swing limiter is connected to the swing arm 1, and the second end is fixed. Limiting the swing range of the swing arm 1 also serves to cushion the swing of the swing arm 1. The swing limiter is preferably a cylinder 5; the first end of the cylinder 5 is a free end connected to the swing arm 1, and the second end of the cylinder 5 is fixedly connected to a mounting member 8. The cylinder 5 is preferably a low-friction cylinder.

[0048] like Figure 1 In one embodiment shown, the swing arm 1 is provided with an adjustment hole 9 for connecting to a swing limiter. Multiple adjustment holes 9 are provided along the length of the swing arm 1, and multiple adjustment holes 9 are located between the connection point between the swing arm 1 and the angle sensor 4 and the second end of the swing arm 1. The swing limiter is connected to different adjustment holes 9 to further control the tension. Preferably, a lug 10 is provided at the second end of the swing arm 1, with an adjustment hole 9 defined in the lug 10. In other words, the connection point between the angle sensor 4 and the swing arm 1 divides the swing arm 1 into a first section and a second section. The swing arm 1 is provided with multiple adjustment holes 9, which are located along the length of the swing arm 1 and in the second section. The free end of the low-friction cylinder is connected to different adjustment holes 9 via a joint, enabling corresponding tension reference values to be obtained. Adjustment holes 9 closer to the connection point between the swing arm 1 and the angle sensor 4 correspond to lower tension values. Conversely, adjustment holes 9 farther away from the connection point between the swing arm 1 and the angle sensor 4 (i.e., closer to the second end of the swing arm 1) correspond to higher tension values. In one example, the low friction cylinder is connected to the adjustment hole 9 of the lug 10, and the maximum tension can reach 90N; in another example, the low friction cylinder is connected to Figure 1 The adjustment hole 9 shown at the bottom can have a minimum tension of 2.5N.

[0049] In one embodiment, the driven roller 2, the air shaft 7 and the swing limiting member are arranged on a first side of the mounting member 8, and the angle sensor 4 is arranged on a second side of the mounting member 8. A wire rod is also arranged on the mounting member 8.

[0050] In general, the device for controlling swing balance tension of the present invention has a reduction motor 3 installed behind the mounting plate, a low-friction cylinder fixes the swing arm 1 in its initial position, a driven roller 2 is installed on the swing arm 1, and the yarn passes around the driven roller 2. When the yarn tension changes, it pulls the swing arm 1 to rotate, and then the angle sensor 4 converts the detected angle of the swing arm 1 into an electrical signal and transmits it to the motor, which then adjusts the tension by rotating the air shaft 7. The air shaft 7 is connected to the reduction motor 3 and driven by the motor. The tail of the air shaft 7 is connected to the air source, and the rubber key strip on the air shaft 7 is raised by inflation to fix the carbon fiber roll 6 on the air shaft 7.
