Description

Technical Field

[0001] This invention relates to the field of carbon fiber container processing equipment, and more particularly to a carbon fiber winding head assembly. Background Technology

[0002] Winding carbon fiber into plastic liners is the main processing method for hydrogen storage cylinders. During the winding process, multiple carbon fiber strands are bundled and wound around the outside of the plastic liner. Currently, the winding of carbon fiber into plastic liners is mostly automated using a winding head assembly. For example, the invention patent disclosed in application number 202410145744.6 (the applicant's prior design) uses a combination of pressure rollers, scissors, and grippers to automatically cut the carbon fiber after winding a single plastic bottle, and then automatically winds the cut ends of the carbon fiber into the plastic liner after the new bottle is in place.

[0003] During actual use, the applicant discovered that the scissors in the initial design were located on the upper side of the grippers. When winding the broken end around a newly positioned plastic bottle, the carbon fiber length between the first pressure roller and the upper edge of the broken end was relatively long. Furthermore, the carbon fiber bundle was prone to becoming disordered during the clamping and loosening process. As a result, the carbon fiber on the upper side of the first pressure roller adhered to the surface of the plastic inner liner, leading to poor adhesion quality. Based on this, the applicant made further improvements to the carbon fiber winding head assembly. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a carbon fiber winding head assembly. By optimizing the design of the lower shearing component and the collection box component, it can remove excess carbon fiber from the upper side of the pressure roller, effectively solving the problems existing in the prior art.

[0005] To address the aforementioned problems, the present invention provides a carbon fiber winding head assembly, comprising a first mounting plate, a winding end mounted on the first mounting plate, and a second mounting plate.

The pressure roller assembly includes a pressure roller frame movably connected to the first mounting plate and a pressure roller disposed on the pressure roller frame. When the clamping assembly clamps the fiber in the clamping position, the pressure roller can be moved by the pressure roller frame to press the fiber between the clamping assembly and the winding end into the plastic inner liner. The lower shear assembly is disposed below the clamping assembly and above the pressure roller assembly, and includes a movable lower shear. When the pressure roller presses the fiber into the plastic liner, the lower shear can move to the fiber position and cut the fiber. A collection box assembly includes a box body with a top opening, the box body being mounted on a second mounting plate, and the clamping assembly being positioned above the box body opening when moved to a release position.

[0006] Furthermore, the opening of the housing is provided with two spaced-apart cleaning rollers, at least one of which is connected to a first motor, and the two cleaning rollers can move in opposite directions or close to each other.

[0008] Furthermore, the mounting bracket is provided with a sliding groove for sliding engagement of the bearing seat, and the collection box assembly also includes a lead screw disposed in the sliding groove and a second motor driving the lead screw to rotate; the bearing seat of one of the cleaning rollers is helically engaged with the lead screw, and the other cleaning roller is connected to the first motor.

[0009] Furthermore, the outer side of the cleaning roller is provided with a fixing rod connected to the bearing seat, and the fixing rod forms a scraper that abuts against the cleaning roller.

[0010] Furthermore, the fixing rod at the position of the cleaning roller connected to the first motor is fixedly connected to the housing, and the other fixing rod is connected to the housing through a deformable connecting piece.

[0014] Furthermore, the lower support includes a telescopic connecting rod, which is fixedly connected to the lower spreading roller, and the lower shears are fixedly installed on the lower spreading roller.

[0015] The beneficial effect of the present invention is that by optimizing the setting of the lower shearing component and the collection box component, excess carbon fiber on the upper side of the pressure roller can be removed, effectively solving the problems existing in the prior art.

[0026] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] In this invention, such as Figure 1-5 As shown, a carbon fiber winding head assembly is provided, including a first mounting plate 1, a winding end 2 mounted on the first mounting plate 1, and a second mounting plate 3. The winding end 2 is provided with a reversing roller 201. The second mounting plate 3 is disposed on the upper side of the winding end 2 and is rotatably connected around a horizontal axis. The second mounting plate 3 is provided with an upper shearing component 4 and a clamping component 5 at intervals from top to bottom. The upper shear assembly 4 is slidably disposed in the second mounting plate 3 in the horizontal direction. The upper shear assembly 4 is movable between the cutting position and the avoidance position. The upper shear assembly 4 includes an openable and closable upper shear 401. The clamping assembly 5 is slidably disposed in the second mounting plate 3 in the horizontal direction. The clamping assembly 5 is movable between a clamping position and a release position. The clamping assembly 5 includes an openable and closable clamp 501. The winding head assembly also includes: A pressure roller assembly is disposed on the lower side of the clamping assembly 5. The pressure roller assembly includes a pressure roller frame 6 movably connected to the first mounting plate 1 and a pressure roller 7 disposed on the pressure roller frame 6. When the clamping assembly 5 clamps the fiber in the clamping position, the pressure roller 7 can be moved by the pressure roller frame 6 to press the fiber between the clamping assembly 5 and the winding end 2 into the plastic inner liner. The lower shear assembly is located on the lower side of the clamping assembly 5 and the upper side of the pressure roller assembly. It includes a movable lower shear 21. When the pressure roller 7 presses the fiber into the plastic liner, the lower shear 21 can move to the fiber position and cut the fiber. The collection box assembly includes a box body 8 with a top opening, the box body 8 being mounted on a second mounting plate 3, and the clamping assembly 5 being located above the opening of the box body 8 when moved to the release position.

[0028] When using the winding head assembly of the present invention, as follows: Figure 2 and 3 As shown, after the new plastic inner liner 18 is in place, the carbon fiber between the clamping assembly 5 and the winding end 2 is pressed against the surface of the plastic inner liner 18 by the pressure roller 7. At this time, the carbon fiber between the pressure roller 7 and the clamp 501 is tensioned. The lower scissors 21 move to the fiber position and cut it at the limit. Figure 4 As shown, clamp 501 moves to the release position. At this time, the carbon fiber held by clamp 501 moves to the upper side of the housing 8, and the carbon fiber fixed by clamp 501 can be released into the housing 8. At this time, it can be wound with the 18 pieces of carbon fiber in the rotating plastic inner liner.

[0029] In the winding head assembly of the present invention, after the new plastic inner liner is in place, when the carbon fiber end is pressed against the plastic inner liner 18 by the pressure roller 7, the lower scissors 21 cut off the part of the carbon fiber end, thereby reducing the length of the carbon fiber end on the upper side of the pressure roller 7, and also preventing the carbon fiber clamped by the clamp 501 from being wound on the plastic inner liner 18, thereby optimizing the winding quality of the carbon fiber end on the plastic inner liner 18.

[0030] In a preferred embodiment, more specifically regarding the structure of the present invention, the opening of the housing 8 is provided with two spaced-apart cleaning rollers 9, at least one of the two cleaning rollers 9 is connected to a first motor 10, and the two cleaning rollers 9 can move in opposite directions or close to each other.

[0031] like Figure 1As shown, by setting up cleaning rollers 9, when the clamp 501 moves the carbon fiber from the clamping position to the release position, there is a sufficient gap between the two cleaning rollers 9 so that the cut part of the carbon fiber can enter between the two cleaning rollers 9. After the clamp 501 moves the carbon fiber to the upper side of the opening of the box 8, the two cleaning rollers 9 are moved close together so that the cleaning rollers 9 clamp the lower end of the carbon fiber. At this time, the clamp 501 releases the carbon fiber, and the first motor 10 drives the cleaning rollers 9 to rotate, which moves the carbon fiber downward to the inside of the box 8, thus completing the release of the carbon fiber.

[0032] In a preferred embodiment, more specifically regarding the structure of the present invention, the mounting frame 11 is provided with a sliding groove 13 for sliding engagement of the bearing seat 12, and the collection box assembly further includes a lead screw 14 disposed in the sliding groove 13 and a second motor 15 driving the lead screw 14 to rotate; the bearing seat 12 of one of the cleaning rollers 9 is helically engaged with the lead screw 14, and the other cleaning roller 9 is connected to a first motor 10.

[0033] like Figure 5 As shown, the gap between the two cleaning rollers 9 can be varied by moving a single cleaning roller 9. The bearing housing 12 of one of the cleaning rollers 9 is fixed to facilitate the rotation of it by the first motor 10.

[0034] In a preferred embodiment, specifically regarding the structure of the present invention, the outer side of the cleaning roller 9 is provided with a fixing rod 16 connected to the bearing seat 12, and the fixing rod 16 forms a scraper 17 that abuts against the cleaning roller 9. Figure 5 As shown, by providing a scraper 17 on the outside of the cleaning roller 9, the carbon fiber adhering to the cleaning roller 9 can be scraped into the housing 8.

[0035] In a preferred embodiment, more specifically regarding the structure of the present invention, the fixing rod 16 at the position of the cleaning roller 9 connected to the first motor 10 is fixedly connected to the housing 8, and the other fixing rod 16 is connected to the housing 8 through a deformable connecting piece.

[0036] like Figure 5 As shown, the connecting piece at the right cleaning roller position can be made of paper or plastic, which can achieve a closed connection between the cleaning roller 9 and the side wall of the box 8 to prevent the carbon fiber inside the box 8 from leaking out.

[0037] In the illustrated embodiment, the mounting bracket 11 of the collection box assembly is connected to the first mounting plate 1. When the second mounting plate 3 rotates, the collection box assembly remains stationary. This is not a limitation of the present invention. In an optional embodiment, the mounting bracket 11 can also be connected to the second mounting plate 3, and the collection box assembly can rotate together when the second mounting plate 3 rotates.

[0038] In a preferred embodiment, specifically regarding the structure of the present invention, the lower shear assembly is mounted on the pressure roller frame 6. For example... Figures 1 to 5 As shown, the pressure roller frame 6 is connected to the first mounting plate 1 via a telescopic rod to enable movement of the pressure roller frame 6. By mounting the lower shear assembly on the pressure roller frame 6, the lower shear 21 can be easily moved to the carbon fiber position near the pressure roller 7 to facilitate cutting the carbon fiber.

[0039] In a preferred embodiment, specifically regarding the structure of the present invention, the lower shearing assembly includes a lower support mounted on the pressure roller frame 6. The lower support is provided with a retractable lower spreading roller 19, and a lower shear 21 is provided on the upper side of the lower spreading roller 19. As shown in the figure, the pressure roller 7 and the lower spreading roller 19 are located on the upper side of the center of the plastic inner liner 18. The carbon fiber on the upper side of the pressure roller 7 extends obliquely to the clamp 501 in a direction away from the plastic inner liner 18. In this way, when the lower shearing assembly needs to cut the carbon fiber, the lower spreading roller 19 moves towards the plastic inner liner 18. During the movement of the lower spreading roller 19 and the lower shear 21, the lower shear 21 located on the upper side of the lower spreading roller 19 cuts the carbon fiber. As the lower spreading roller 19 moves further towards the plastic inner liner 18, the carbon fiber cut-off end on the upper side of the pressure roller 7 is spread onto the surface of the plastic inner liner 18, thereby further ensuring the winding quality of the carbon fiber end position on the plastic inner liner 18.

[0040] In a preferred embodiment, specifically regarding the structure of the present invention, the end of the lower support away from the lower scissors is rotatably connected to the pressure roller frame. For example... Figure 1 As shown, the lower support has a telescopic connecting rod 20 at the end of the lower spreading roller 19 away from the lower shear. The connecting rod 20 is hinged to the pressure roller frame 6 so that after the lower spreading roller 19 abuts against the plastic inner liner 18, the swing of the connecting rod 20 can move the lower spreading roller 19 on the surface of the plastic inner liner 18, thereby further improving the winding quality of the carbon fiber break and preventing the lower spreading roller 19 from generating compressive stress between the plastic inner liner 18 due to the extension of the connecting rod 20.

[0041] In a preferred embodiment, specifically regarding the structure of the present invention, the lower support includes a retractable connecting rod 20, which is fixedly connected to the lower spreading roller 19, and the lower shears 21 are fixedly mounted on the lower spreading roller 19. Figure 1 As shown, by using a lower spreading roller 19 that is fixedly connected to the connecting rod 20, the structure of the lower spreading roller 19 can be simplified compared to using a rolling lower spreading roller 19, and the difficulty of assembling the lower shears 21 and the lower spreading roller 19 can also be reduced.

[0042] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0043] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
