Description

Technical Field

[0001] The present invention relates to the technical field of gas cylinder production, and particularly relates to a precise glue control device and a glue control method for the wet winding process of gas cylinders. Background Art

[0002] In the context of today's energy transformation and sustainable development, hydrogen energy, as a clean and efficient new energy source, has attracted much attention. However, the large-scale application of hydrogen energy faces many challenges, among which the bottleneck of hydrogen energy storage and transportation technology is particularly prominent. Hydrogen energy storage and transportation technology is a crucial link in the hydrogen energy industry chain, directly related to whether hydrogen energy can be safely and efficiently transported and used, thus affecting the development process of the entire hydrogen energy industry.

[0003] Currently, there are mainly four common hydrogen energy storage methods: high-pressure gaseous hydrogen storage, cryogenic liquid hydrogen storage, solid hydrogen storage, and organic liquid hydrogen storage. These several hydrogen storage methods have their own characteristics and application scenarios. Solid hydrogen storage uses hydrogen storage alloys or nanomaterials, etc. to adsorb and release hydrogen, with advantages such as high hydrogen storage density and good safety, but the current technology is not yet fully mature and the cost is relatively high. Organic liquid hydrogen storage stores hydrogen by chemically reacting hydrogen with organic substances to form liquid compounds, and can be stored and transported at normal temperature and pressure, but the hydrogen storage and hydrogen release processes require a certain amount of energy input and complex equipment. Cryogenic liquid hydrogen storage requires cooling hydrogen to an extremely low temperature (about -253°C) to liquefy it to increase the hydrogen storage density, but this requires a large amount of energy for refrigeration, and has extremely high requirements for the adiabatic performance of the equipment, with high costs.

[0004] In contrast, high-pressure gaseous hydrogen storage technology is relatively mature and widely used. The hydrogen storage device it uses - gas cylinders, is specially designed and manufactured. The process of producing composite gas cylinders involves winding fibers impregnated with resin on the inner liner, and then completing the process through curing and forming. This process mainly has two process methods: wet winding and dry winding.

[0005] Wet winding occupies a dominant position in actual production due to its advantages such as high efficiency, low cost, and simple process. However, wet winding also has some obvious deficiencies. For example, the working environment is poor, and phenomena such as glue splashing are likely to occur during the winding process, which has a certain impact on the physical health of operators and the cleanliness of the working environment. Moreover, during the wet winding process, the resin content fluctuates greatly, which may lead to uneven quality of gas cylinders. The phenomenon of glue waste is also relatively common, which not only increases production costs but may also cause environmental pollution. At the same time, due to the instability of the resin content after winding, manual scraping of glue is often required to adjust, which will undoubtedly reduce production efficiency.

[0006] Although dry winding avoids the above problems to a certain extent, it has not been able to be popularized on a large scale due to factors such as cost and equipment manufacturing difficulty.

[0007] During the wet winding process, precisely controlling the resin content of the fibers during the winding of gas cylinders is an extremely crucial technical problem. When the resin content is too high, the weight of the gas cylinder will increase accordingly, which undoubtedly violates the original design intention of minimizing the weight of the gas cylinder while ensuring its performance. Moreover, a resin-rich situation will occur, which will interfere with the normal performance of the fibers, resulting in a decrease in the strength of the gas cylinder and affecting its overall mechanical properties. The cured resin nodules not only affect the aesthetic appearance of the gas cylinder but may also become stress concentration points, reducing the service life of the gas cylinder. On the contrary, if the resin content is too low, the yarn may not be fully unwound during the winding process, resulting in gaps on the surface of the gas cylinder. In severe cases, dry yarn phenomenon may even occur, damaging the sealing performance and structural integrity of the gas cylinder, and thus affecting its hydrogen storage performance. In addition, the internal air cannot be discharged smoothly, and bubbles are likely to be generated inside the gas cylinder after curing. The existence of these bubbles will weaken the structural strength of the gas cylinder and become potential safety hazards.

[0008] Given the current status of wet winding as the mainstream process, it is particularly important to solve the problem of controlling the resin content. Controlling the resin content not only can significantly improve the performance and appearance quality of the gas cylinder but also can effectively avoid the pollution of the working environment caused by resin dripping, reduce or even completely eliminate the manual resin scraping process, thereby greatly improving production efficiency and reducing production costs. This will contribute to the further development of high-pressure gaseous hydrogen storage technology and lay a solid foundation for the large-scale application of hydrogen energy and the prosperity of the entire hydrogen energy industry.

A gasket 10 is provided between the movable fixing part 3 and the coarse adjustment groove 101 of the support rod 1 to improve the reliability when the scraper is fixed.

[0042] The second adjustment mechanism includes an adjusting lifting element 4 and an adjusting driving element 5; the adjusting lifting element 4 passes through the support rod 1 and the scraper 2 in sequence, and one end thereof extending into the scraper 2 has two inclined contact parts 401; the scraper 2 is provided with a constraint part 201 matching the contact parts 401; the contact parts 401 cooperate with the constraint part 201 to convert the lifting movement of the adjusting lifting element into the horizontal movement of the scraper 2; among them, the two contact parts 401 are symmetrically arranged with respect to the axis of the adjusting lifting element 4 to synchronously abut against the constraint part 201 during the lifting process, restricting the deflection freedom of the scraper 2; the lifting movement of the adjusting lifting element 4 is driven by rotating the adjusting driving element 5; the adjusting driving element 5 is a nut or a threaded knob.

[0043] Furthermore, the end of the adjusting lifting element 4 extending into the squeegee 2 has a rectangular body structure, and the contact part 401 is arranged on this rectangular body structure and is a semi-conical protrusion; the two contact parts 401 are arranged in an inclined symmetry with respect to the axis of the adjusting lifting element 4. The restraining part 201 of the squeegee 2 is an L-shaped groove, and the bending direction of this L-shaped groove is consistent with the width direction of the squeegee 2.

[0044] Each squeegee 2 corresponds to two sets of first adjusting mechanisms and second adjusting mechanisms respectively arranged at both ends of the squeegee.

[0051] Embodiment

[0052] The precise glue control device for the wet winding process of gas cylinders in this embodiment includes a support rod 1 and three scrapers 2 installed on the support rod 1. A set of first adjustment mechanisms and a set of second adjustment mechanisms are provided at both ends of each scraper 2, and the support rod 1 is connected to a control mechanism.

[0053] In this embodiment, the support rod 1 is integrally processed from alloy steel to ensure its straightness. The front end of the scraper 2 has a cutting edge for scraping glue.

[0054] Among them, the first adjustment mechanism includes a coarse adjustment slot 101 provided on the support rod 1 and a movable fixing member 3. The movable fixing member 3 passes through the coarse adjustment slot 101 and is connected to the threaded hole of the scraper 2 for roughly adjusting the position of the scraper 2. Among them, in this embodiment, the coarse adjustment slot 101 is an oblong slot extending in a direction perpendicular to the axial direction of the support rod, and the movable fixing member 3 is a bolt. A gasket 10 is also provided between the movable fixing member 3 and the coarse adjustment slot 101 of the support rod 1 to improve the reliability when the scraper is fixed.

[0055] The second adjustment mechanism includes an adjustment lifting element 4 and an adjustment driving element 5; the adjustment lifting element 4 is sequentially inserted through the support rod 1 and the scraper 2, and the end of it extending into the scraper 2 has two inclined contact parts 401. In this embodiment, the end of the adjustment lifting element 4 extending into the scraper 2 is a rectangular body structure, and the contact parts 401 are arranged on this rectangular body structure and are semi-conical protrusions; the two contact parts 401 are symmetrically inclined with respect to the axis of the adjustment lifting element 4.

[0056] The two sets of first adjustment mechanisms and second adjustment mechanisms corresponding to each scraper 2 constitute two adjustment points, which can not only achieve the parallelism calibration of the scraper in a single station, but also solve the adjustment problem that the three scraper stations cannot have consistent glue gaps due to insufficient machining accuracy of the glue tank, and can achieve calibration and more effective coarse adjustment of the glue gap.

[0057] The scraper 2 is provided with a constraint part 201 matching the contact part 401; in this embodiment, the constraint part 201 of the scraper 2 is an L-shaped groove, and the bending direction of this L-shaped groove is consistent with the width direction of the scraper 2. The contact part 401 of the adjustment lifting element 4 cooperates with the constraint part 201 of the scraper 2, so that the lifting movement of the adjustment lifting element 4 is converted into the horizontal movement of the scraper (horizontal movement perpendicular to the axial direction of the support rod); because the two contact parts 401 are symmetrically inclined with respect to the axis of the adjustment lifting element 4, they can simultaneously abut against the constraint part 201 during the lifting process to limit the deflection freedom of the scraper 2.

[0058] In this embodiment, the adjustment driving element 5 is a nut, which is connected to the upper end of the adjustment lifting element 4 by a thread. The lifting movement of the adjustment lifting element 4 is driven by rotating the adjustment driving element 5.

[0059] Bearings 11 are also installed at both ends of the support rod 1. The control mechanism includes a cantilever 6 connected to one end of the support rod 1 and a drive unit. The drive unit controls the movement of the support rod 1 through the cantilever 6 so that the squeegee 2 reaches the glue control position. Specifically, the drive unit includes an electric cylinder 7, a reduction motor 8, and a servo motor 9 connected in sequence. The electric cylinder 7 is connected to the support rod 1. The electric cylinder 7 is controlled by the reduction motor 8 and the servo motor 9 to drive the cantilever 6 to move. The reduction motor 8 controls the speed. The servo motor 9 is controlled by a PLC program and is linked with the host computer to achieve precise control.

[0060] The precise glue control method for the wet winding process of gas cylinders based on the precise glue control device of this embodiment includes the following steps:

[0061] S1, coarsely adjust the fixed position of the squeegee 2 on the support rod 1 through the cooperation of the movable fixing member 3 and the coarse adjustment groove 101;

[0062] S2, turn the adjustment drive element 5 to make the adjustment lifting element 4 move up and down. Through the cooperation of the conical surface of the contact part 401 of the adjustment lifting element 4 and the constraint part 201 of the squeegee 2, make the squeegee 2 move horizontally to further adjust the position of the squeegee 2 and calibrate the parallelism of the squeegee 2 relative to the glue printing roller and the glue gap consistency of the three squeegees 2;

[0063] S3, after the squeegee position (glue control position) is determined, drive the cantilever 6 to move through the drive unit, so as to place the squeegee 2 at the glue control position through the support rod 1, and then perform the glue scraping work according to the process requirements during the winding process.

[0064] In the present invention, the position of the squeegee is coarsely adjusted through the cooperation of the coarse adjustment groove 101 and the movable fixing member 3 to coarsely adjust the glue passing gap between the squeegee 2 and the glue printing roller. Then, the horizontal movement of the squeegee 2 is realized through the cooperation of the adjustment lifting element 4 and the squeegee 2, further precisely adjusting the squeegee position and realizing the parallelism calibration of the squeegee. After one adjustment, after the glue control position is determined, during each operation, the squeegee 2 can be directly driven to the glue control position through the cooperation of the drive unit and the cantilever 6, without further adjustment.

[0065] The adjustment lifting element 4 of the present invention cooperates with the constraint part 201 of the squeegee 2 through its inclined contact part 401. While realizing the horizontal movement of the squeegee through the lifting movement, the deflection and shaking of the squeegee 2 can be eliminated, avoiding local glue enrichment / glue shortage caused by uneven gaps, and realizing precise glue control.

[0066] The present invention can be applied to various glue tank structures, can precisely control the glue in the glue tank of a multi-station winding machine, and ensure the consistent glue content of multi-station wound gas cylinders.

[0067] The glue control device and method of the present invention can realize the adjustment of the glue scraping gap of the scraper, achieve precise glue control, effectively control the glue content of wet-wound gas cylinders, avoid the situations of resin-rich and glue-deficient, improve the utilization rate of fibers, enhance the strength of gas cylinders, avoid problems such as glue tumors and bubbles after the curing of gas cylinders, improve the product quality, can control the weight of the winding composite layer of gas cylinders, and then can precisely control the weight of gas cylinders. At the same time, it can prevent the dripping of glue liquid from polluting the environment, avoid the waste of glue liquid, eliminate the need for manual glue scraping, improve the efficiency, and reduce the labor cost.
