Description

Technical Field

[0001] The invention belongs to the technical field of fiber winding, and in particular relates to a defect-free winding tool for aramid fibers in plastic liners used in the manufacture of IV-type hydrogen storage cylinders. Background Art

[0002] In the manufacturing of Type IV hydrogen storage cylinders, the aramid fiber (or carbon fiber) winding process is a key link, which directly affects the sealing, burst strength, fatigue life, etc. of the cylinder; traditional technology mostly uses a single fiber bundle (such as 3,000 aramid fibers or 6,000 aramid fibers) to be spirally or circumferentially wound through a wire guide head. The fiber arrangement is fixed, and it is difficult to dynamically adjust the fiber spacing or arrangement pattern, which causes the fiber bundles to easily separate or overlap, resulting in a high interlayer porosity (reaching 2%~3%). In addition, especially in areas with large curvature changes such as the head or transition zone, the traditional wire plate cannot ensure the fiber fit and is prone to "bridging" phenomenon, which directly causes the local strength of the hydrogen storage cylinder liner to decrease.

[0030] In the embodiment, the contact surface of the top tooth ring 6 and the tooth disc 61 is provided with a sawtooth structure, so that when the main roller body 51 and the positioning shaft 55 rotate relative to each other, the top tooth ring 6 on the main roller body 51 can realize small amplitude sliding of the main roller body 51 in the rotation through the alternating action of the tooth peak and the tooth groove, and high frequency micro amplitude axial oscillation is generated, at this time, the aramid fiber between the upper and lower main roller bodies 51 can be gathered (or dispersed) to the middle part under the guiding action of the sliding of the main roller body 51, so that the fiber is driven to the middle line by the friction force of the roller surface to form a dense arrangement (the fiber spacing is reduced by 30%~50%); and the main roller bodies 51 and the fixed rollers 53 arranged above and below are driven through gear meshing.

[0031] As a preferred embodiment, the main roller body 51 is provided with an air bag sleeve 62, and a plurality of air vents 63 are formed in the main roller body 51; the inner shaft 54 is provided with an airflow channel 57, and a plurality of micro air holes are formed on the surface of the inner shaft 54 at the air vents 63; it should be noted that a plurality of air vents 63 can also be provided, and each micro air hole can always be sealed and communicated with the air vent 63, and as the best, an annular air guide groove can be formed in the inner wall of the main roller body 51 at the air vent 63, and the micro air hole can be in a continuous communication state with the annular air guide groove, so as to ensure the airflow communication between the micro air hole and the air vent 63.

[0032] The positioning shaft 55 is externally sealed and rotationally connected with an air pressure pipe 64, which is communicated with the airflow channel 57 through a central air channel formed in the positioning shaft 55; that is, when the top tooth ring 6 on the main roller body 51 relatively rotates with the tooth disc 61 and the tooth peaks are in contact, the main roller body 51 relatively moves away from the fixed roller 53, and the air bag sleeve 62 on the main roller body 51 can be in a slightly expanded state by the air supply of the airflow channel 57, the aramid fiber can be extruded and contacted on the main roller body 51 on the opposite side by the air bag sleeve 62, and the main roller body 51 gradually rotates, the tooth peaks of the top tooth ring 6 slide into the tooth grooves of the tooth disc 61, the main roller body 51 axially slides and approaches the fixed roller 53, at this time, the air bag sleeve 62 gradually deflates, the extrusion effect on the aramid fiber gradually weakens, and when the tooth peaks of the top tooth ring 6 are out of the tooth grooves of the tooth disc 61, the air bag sleeve 62 gradually inflates to gather the aramid fiber transmitted between the main roller bodies 51 to the center line.

[0033] The outer support 65 is fixed on one side of the fiber separating frame 5 close to the fixed roller 53, the outer support 65 is rotationally connected with a clamping jaw 66, the side wall of the positioning shaft 55 is circumferentially distributed with a plurality of clamping grooves 67, and one end of the clamping jaw 66 is clamped with the clamping grooves 67; the outer support 65 is connected with a control cylinder 68, and the other end of the clamping jaw 66 is rotationally connected with the extension end of the control cylinder 68; in this embodiment, when the aramid fiber is gathered, the clamping jaw 66 can be clamped with the clamping grooves 67 in the contraction state of the control cylinder 68, at this time, the positioning shaft 55 is in a relatively static state, and the main roller body 51 relatively rotates with the positioning shaft 55; in the normal transmission process of the aramid fiber, the clamping jaw 66 is separated from the clamping grooves 67, the positioning shaft 55 can be driven to rotate synchronously with the main roller body 51 by the tooth surface biting effect, and the main roller body 51 can stably transmit the aramid fiber.

[0034] In this embodiment, the fiber laying unit 3 comprises a fiber laying pipe 31, two liquid immersion cavities 32 are distributed on the inside of the fiber laying pipe 31, a fiber feeding hole is formed on one side of the fiber laying pipe 31, and a plurality of pressure rollers 33 are arranged in the liquid immersion cavities 32; resin is arranged in the liquid immersion cavities 32, and the aramid fiber can be preferentially immersed in the resin; the fiber laying pipe 31 is also fixed with a fiber laying frame 34 symmetrically above and below, and a wire roller group 35 is arranged at one end of the fiber laying pipe 31 close to the fiber laying frame 34.

It should be noted that when the fiber filaments are dynamically adjusted in position, the fiber filaments will inevitably have intersection points, therefore, the tensioning wheel 45 can be used to provide a certain tension effect to the fiber filaments when they are wound on the inner surface of the gas cylinder liner at the intersection points, so as to reduce the protruding thickness of the intersection points (the fiber filaments can also be softened by pulse infrared heating (200℃×0.5s) and then lightly pressed to make the fiber filaments adhere to each other).

[0036] For example, in the preliminary annular winding, the fiber filaments in one group of aramid fibers can be divided into two bundles and arranged on both sides of the other group of aramid fibers, at this time, the aramid fibers can press and combine the fiber filaments of the previous winding layer by the fiber filaments at the edge in the annular tight winding, so as to ensure the tight effect in the preliminary winding.

[0037] In the embodiment, the heights of the wire guide plates 37 are different.
