Description

Technical Field

[0001] The present invention relates to the field of carbon fiber container processing equipment, and in particular to a carbon fiber gas cylinder pre-coating device. Background Art

[0002] Carbon fiber wrapping around a plastic liner is the primary method for manufacturing hydrogen storage cylinders. During this process, multiple carbon fiber strands are wound in bundles around the outside of the plastic liner. After wrapping, the cylinders need to be cured at a specific temperature in a curing chamber.

[0003] At present, the common processing methods for plastic liners are injection molding and rotational molding. Since the outer surface of the plastic liner often has tiny bumps and depressions, the carbon fiber after being impregnated with glue is easily wrapped with bubbles on the surface of the plastic liner during winding. As a result, bubbles are formed between the plastic liner and the carbon fiber and glue after the gas cylinder is formed. During the internal inflation and deflation process, the liner is prone to distortion points at the position of the bubbles, causing the liner to gradually separate from the carbon fiber or glue, affecting the stability of the gas cylinder.

[0004] In response to this, the applicant usually applies glue to the surface of the plastic liner using a handheld scraper before winding the plastic liner. This method requires high manual coating skills and physical strength, and the strength and thickness of the applied glue layer are difficult to control, and bubbles are easily left between the glue layer and the plastic liner.

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0021] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] In the present invention, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or interactions between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected only through a connecting structure to form a whole. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. In the description of the present application, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0025] In the present application, as shown in Figure 1-3 A carbon fiber gas cylinder pre-coating device is provided, which can be arranged below the rotatable liner 1, comprising: a glue groove 2, the glue groove 2 is provided with an open top containing cavity; glue applying part 3 is arranged between the glue groove 2 and the liner 1, the glue applying part 3 includes a glue applying part, the glue applying part can apply glue in the glue groove 2 to the surface side of the liner 1; The top pressing part 4 is arranged on one side of the glue applying part 3 in the rotation direction of the liner 1, and the top pressing part can abut against the liner 1; The glue scraping part 5 is arranged on one side of the top pressing part 4 in the rotation direction of the liner 1, and the glue scraping part 5 includes a glue scraping plate 501 abutting against the surface side of the liner 1.

[0026] The pre-coating device of the present application is used, as shown in Figure 1 The two ends of the liner 1 are fixed on the rotatable tool (which can be fixed on the carbon fiber winding station). The glue groove 2 is moved to the bottom of the liner 1, so that the top pressing part 4 abuts against the liner 1. At this time, the liner 1 can be rotated, and at the same time, the glue applying part 3 of the glue applying part 3 applies a glue layer to the liner 1, and the glue layer is deformed locally when it is rotated to the position of the top pressing part 4, and the glue layer is deformed locally. The glue and bubbles combined on the surface side of the liner 1 are extruded, so that the glue can be extruded to contact the liner 1, and the bubbles are extruded to separate from the liner 1, and at the same time, the top pressing part can remove the excess glue on the surface side of the liner 1 by pressing, so that a small amount of glue is left on the surface side of the liner 1. In this way, the content of bubbles in the excess glue is further reduced. When the liner 1 is rotated to the position of the glue scraping plate 501, the glue scraping plate 501 can further scrape the glue left on the surface side of the liner 1, so that the glue on the surface side of the liner 1 is more evenly distributed, and at the same time, the bubbles in the glue are removed during the scraping process.

[0027] In a preferred embodiment, for the structure of the present invention, more specifically, the glue coating unit includes a glue coating roller 301, the two ends of the glue coating roller 301 are respectively contracted to form a necking section 3011, and a glue baffle 3012 is provided on the outside of the necking section 3011. The outer edge of the glue baffle 3012 extends outward from the necking section 3011. The portion of the glue coating roller 301 between the necking sections 3011 forms a glue coating section, and the lower end of the glue coating section is immersed in the glue tank 2. Figure 1 and Figure 2 As shown, by providing a necking section 3011 on the glue coating roller 301, the glue impregnated on the glue coating section can be blocked by the glue baffle 3012 after moving laterally to the necking section 3011 to prevent the glue from moving out of the side of the glue coating roller 301.

[0028] As for the rotation mode of the glue coating roller 301, it is preferred to set a special motor to drive the rotation for glue coating, and at this time a gap can be reserved between the glue coating roller 301 and the inner liner 1. In an optional embodiment, the glue coating roller 301 can also be in contact with the inner liner 1 for glue coating.

[0029] exist Figure 1 In the embodiment shown, both the glue coating roller 301 and the pressing member 4 are provided with a vertical telescopic rod 6 to facilitate adjustment of the distance between the inner liner 1 and the glue coating roller 301 .

[0030] In a preferred embodiment, for the structure of the present invention, more specifically, the pressing member 4 includes a rotatable pressing roller 401 , and the pressing roller 401 abuts against the inner container 1 .

[0031] The arrangement of the top pressure member 4 is not limited to Figure 1 The form of the pressing roller 401 is shown in the figure. In an optional embodiment, other forms can also be used, such as using a fixed roller to abut against the inner liner 1.

[0032] In order to further improve the bubble removal effect, in a preferred embodiment, the structure of the present invention is further optimized in that the surface side of the pressing roller 401 is provided with concave and convex patterns.

[0033] like Figure 1As shown, by setting the concave and convex lines, when the liner 1 is pressed, the convex position will directly press the liner 1 to further extrude the glue and the liner 1 separated by the bubble at the corresponding position to reduce the bubble content on the surface side of the liner 1. The glue at the concave position is extruded to flow, which can promote the flow of the glue at the convex position carrying the bubble, further reducing the bubble retention at the convex position. The flow of the glue under pressure at the concave position promotes the contact between the glue and the liner 1, which can further reduce the bubble content on the surface side of the liner 1 at the concave position. At the same time, the concave lines can retain part of the glue to provide enough glue for the scraping member 5 to operate when the scraping member 5 scrapes the retained glue. During the further scraping process of the scraping member 5, the bubbles in the retained glue are further released.

[0034] In a preferred embodiment, for the structure of the present application, further specifically, the pressing roller 401 is provided as a metal roller body, and the pressing member 4 further comprises a telescopic rod 6 connected with the metal roller body. As shown in Figure 1 and Figure 2 As shown, by setting the telescopic rod 6, when it is needed to move the position of the pressing roller 401, the telescopic rod 6 can be retracted to drive the pressing roller 401 away from the liner 1. The telescopic telescopic rod 6 can also be used to adjust the pressing force between the pressing roller 401 and the liner 1.

[0035] In a preferred embodiment, for the structure of the present application, further optimization is that the center of the pressing roller 401 is located on one side of the center of the liner 1 in the rotation direction of the liner 1.

[0036] As shown in Figure 2 In this way, the glue on the surface side of the liner 1 can be extruded downward before entering the pressing area of the pressing roller 401, and the extruded bubbles are also driven to flow downward. After the liner 1 moves upward out of the pressing area of the pressing roller 401, the glue layer becomes thinner, and the remaining bubbles in the glue layer are more easily released.

[0037] In a preferred embodiment, for the structure of the present application, further optimization is that the scraping plate 501 comprises a scraping plate body 5011 and an arc-shaped portion 5012 formed on one side of the scraping plate body 5011, the arc-shaped portion 5012 is provided as an arc-shaped protrusion towards the liner 1; the scraping plate body 5011 is provided as elastic to keep the arc-shaped portion 5012 in abutment with the liner 1.

[0038] As shown in Figure 2As shown, by providing an upwardly convex curved portion 5012 in contact with the inner liner 1, the curved portion 5012 can be used to gradually spread and smooth out the remaining glue on the surface of the inner liner 1, further improving the uniformity of the remaining glue. At the same time, the elastic contact between the curved portion 5012 and the inner liner 1 can block and scrape away excess glue, along with bubbles in the glue, into the glue groove 2. This allows the inner liner 1 to form a thin glue layer after being scraped by the curved portion 5012.

[0039] In a preferred embodiment, for the structure of the present invention, a further optimized setting is that the scraper plate body 5011 is folded upward and extended on one side away from the top pressure member 4 to form a glue coating groove 7; the glue coating device also includes a scraper plate 8, which is arranged on the side of the scraper plate 501 located in the rotation direction of the inner liner 1, and there is a gap between the scraper plate 8 and the inner liner 1.

[0040] like Figure 2 As shown, after the inner container 1 rotates past the scraper body 5011, the glue in the glue coating groove 7 can be transferred to the surface of the inner container 1, thereby forming a glue layer of a certain thickness on the surface of the inner container 1. After the inner container 1 and the glue layer rotate to the position of the scraper plate 8, the scraper plate 8 can scrape off excess glue to make the thickness of the surface of the inner container 1 uniform.

[0041] The present invention, by providing a scraper body 5011, a glue coating groove 7, and a scraper plate 8, has the following advantages when forming a glue layer of stable thickness: the excess glue scraped off by the curved portion 5012 contains some bubbles that have been destroyed by bubbles attached to the surface of the inner liner 1. Scraping off this portion of glue by the curved portion 5012 can further reduce the bubble content in the glue on the surface of the inner liner 1. The curved portion 5012 contains glue in the glue groove 2, which is located in the portion away from the top pressure member 4. This allows the inner liner 1 to be stained with glue after rotating past the curved portion 5012. This reduces the possibility of bubbles being mixed in during the process of glue from the glue coating groove 7 being stained by the inner liner 1, further reducing the amount of bubbles remaining in the glue layer on the surface of the inner liner 1 after glue coating. Using the curved portion to scrape off excess glue can easily control the thickness of the glue layer.

[0042] exist Figure 1 In the embodiment shown, for the structure of the present invention, to be more specific, the glue coating device includes a connecting bracket 9 connected to the glue groove 2, the connecting bracket 9 is configured to slide relative to the glue groove 2, and a driving member is provided between the connecting bracket 9 and the glue groove 2; the end of the scraper plate 501 away from the arc-shaped portion 5012 is provided with a mounting bracket 10, and the mounting bracket 10 is connected to the connecting bracket 9; the scraper plate is slidably mounted on the mounting bracket 10.

[0043] As shown in the figure, by providing a driving member, when the inner liner 1 needs to be coated with glue, the connecting bracket 9 is first moved by the driving member to make the arc portion 5012 contact the inner liner 1, and then the scraping plate 8 is moved toward the inner liner 1 to facilitate the operation. When the entire coating device needs to be moved horizontally, the scraping plate and the arc portion 5012 can be driven by the driving member as a whole to move away from the inner liner 1. Figure 1 In the embodiment shown, the scraping plate is mounted on the outer end of the mounting frame, and the distance between the scraping plate and the plastic liner can be adjusted by pulling and moving the scraping plate.

[0044] exist Figure 1 In the embodiment shown, the structures of the scraper plate 501 and the scraper plate 8 are further specifically described as follows: Figure 2 As shown, the scraper body 5011 extends obliquely upward in an arc shape and is connected to the scraper plate 8. Side edges for constraining glue are provided on both sides of the scraper body 5011, so as to gather the glue to flow to the arc portion 5012.
