Description

Technical Field

[0001] The present invention relates to the field of carbon fiber container processing equipment, in particular to a fiber winding device for a large-capacity storage box. Background Art

[0002] Carbon fiber winding is a key process for large tanks, with wet winding being a common process. During wet winding, the carbon fibers are dipped in a glue tank and then guided to the tank via a guide wheel. Winding is achieved by rotating the tank.

[0003] Since most storage tanks are irregular in shape, and large-volume storage tanks (tank diameter at its maximum position is generally more than 120 cm, which is considered a large-volume carbon fiber storage tank) have a large change in the carbon fiber winding position during the winding process, which leads to a large change in the tension of the storage tank during the carbon fiber winding process. In order to reduce the impact of carbon fiber tension changes on the impregnation quality and winding quality, the carbon fiber winding tension needs to be controlled.

[0004] In a tension control device for a fiber winding process disclosed in application number 202410024884.8, a movable pulley is arranged on the rear side of the dipping roller, and a cylinder is used to drive the movable pulley up and down to adjust the tension of the carbon fiber during the tank winding process.

[0005] During the winding process of the storage tank, the movable pulley moves up and down to adjust the tension of the carbon fiber. Since the cylinder actively drives the movable pulley to move, there is a response time difference in the tension and speed changes between the carbon fiber on the side of the movable pulley facing the rubber roller and the carbon fiber on the side facing the storage tank. For example, when the movable pulley actively moves downward, the carbon fiber on the side of the movable pulley facing the storage tank is quickly guided to the winding storage tank, and the tension and linear speed of the carbon fiber on the side of the movable pulley facing the rubber roller fluctuate instantaneously. After this fluctuation is transmitted to the rubber roller, the carbon fiber is prone to local rubbing when it is dipped in the rubber roller, affecting the quality of the carbon fiber dipping. Therefore, how to reduce the tension and speed fluctuations during tension adjustment is a technical problem that needs to be solved urgently for carbon fiber dipping. Summary of the Invention

[0024] 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.

[0025] 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.

[0027] 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.

[0028] In the present invention, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] In the present invention, Figures 1-4 As shown, a large-capacity storage box fiber winding device is provided, including a rubber roller 1, with guide rollers 2 provided on both sides of the rubber roller 1, the rubber roller 1 having an inlet side and an outlet side, the winding device also including a reversing roller 3 provided on the outlet side of the rubber roller 1, a tension adjustment roller 4 that can be raised and lowered is provided between the reversing roller 3 and the guide roller 2 at the corresponding position, a first driving member that drives the tension adjustment roller 4 to move up and down, a compensating roller 5 that can move laterally is provided on the side of the tension adjustment roller 4 facing the guide roller 2 at the corresponding position, and the winding device also including a second driving member that drives the compensating roller 5 to move laterally The carbon fiber passes around the lower side of the guide roller 2 on the introduction side, passes around the upper side of the rubber roller 1, passes around the lower side of the guide roller 2 on the lead-out side, passes around the compensation roller 5, passes around the upper side of the tension adjustment roller 4, and passes around the lower side of the reversing roller 3; when the first driving member drives the tension adjustment roller 4 to move upward, the second driving member drives the compensation roller 5 to move to drive the carbon fiber to move toward the side edge of the corresponding position of the tension adjustment roller 4; when the first driving member drives the tension adjustment roller 4 to move downward, the second driving member drives the compensation roller 5 to move to drive the carbon fiber to move away from the side edge of the corresponding position of the tension adjustment roller 4.

[0030] When the winding device of the present invention is used, Figures 1 to 4 As shown, during the winding process of the carbon fiber in the storage tank, when it is necessary to adjust the tension of the carbon fiber by driving the tension adjustment roller 4 up and down through the first driving member, the present invention can drive the compensation roller 5 to move synchronously through the second driving member. Specifically, as Figure 3 and Figure 4As shown, when the tension adjustment roller 4 moves downward, the compensation roller 5 moves away from the rubber roller 1, so that the compensation roller 5 can tighten and speed up the carbon fibers between the corresponding reversing rollers 3, thereby reducing the fluctuations caused by the decrease in carbon fiber tension and the decrease in speed at the rubber roller 1 caused by the downward movement of the tension adjustment roller 4. When the tension adjustment roller 4 moves upward, the compensation roller 5 moves toward the rubber roller 1, so that the compensation roller 5 can release and slow down the carbon fibers between the corresponding reversing rollers 3, thereby reducing the fluctuations caused by the increase in carbon fiber tension and the increase in speed at the reversing roller 3 caused by the upward movement of the tension adjustment roller 4.

[0031] It can be seen that the present invention can reduce the tension and speed fluctuations caused by the active up and down movement of the tension adjustment roller 4 on the carbon fibers at the rubber roller 1, so that the carbon fibers can be stably dipped in the rubber roller 1, thereby optimizing the dipping quality of the carbon fibers.

[0032] It should be noted that the improvement of the present invention lies in the tension control part of the carbon fiber winding process, and no restrictions are made on the improvements to other structural links in the carbon fiber winding process. Those skilled in the art can implement it flexibly in specific implementation, such as the carbon fiber supply bin, carbon fiber winding arm, etc.

[0033] In a preferred embodiment, for the structure of the present invention, to be more specific, the first driving member is configured as a first electrically-controlled telescopic rod 6, the second driving member includes a compensation frame 7, a push rod 8 that can slide laterally on the compensation frame 7, and the push rod 8 is connected to the compensation roller 5; a reversing linkage mechanism is provided between the push rod 8 and the first electrically-controlled telescopic rod 6, and the reversing linkage mechanism is configured to convert the vertical movement of the first electrically-controlled telescopic rod 6 into driving the push rod 8 to move laterally.

[0034] In an embodiment of the present invention in which a reversing linkage mechanism is provided, the vertical movement of the telescopic end of the electrically controlled telescopic rod can be converted into lateral movement of the push rod 8 through a mechanical reversing structure. The mechanical reversing structure can be used to maintain the synchronization of the above-mentioned vertical movement and lateral movement, so as to further improve the effect of reducing the tension and speed fluctuations of the carbon fiber during the tension adjustment process.

[0035] As an embodiment of a reversing linkage mechanism, to be more specific, the reversing linkage mechanism includes a rotating seat 9, a drive shaft 10 rotatably arranged on the rotating seat 9, and a lower connecting rod 11 arranged on the drive shaft 10: the drive shaft 10 is transmission-connected to the telescopic end of the first electrically-controlled telescopic rod 6, so that when the telescopic end of the first electrically-controlled telescopic rod 6 moves vertically, the drive shaft 10 is driven to rotate; the lower connecting rod 11 is slidingly connected to the push rod 8 along the extension direction of the lower connecting rod 11, so that when the lower connecting rod 11 rotates, the push rod 8 is driven to move back and forth laterally.

[0036] like Figure 3 As shown, when the telescopic end of the first electrically controlled telescopic rod 6 moves vertically, the drive shaft 10 rotates, and the rotation of the drive shaft 10 drives the lower connecting rod 11 to swing left and right. A connecting seat 802 is provided on the push rod 8. When the lower connecting rod 11 swings left and right, the connecting seat 802 drives the push rod 8 to move horizontally, thereby realizing the lateral movement of the compensation roller 5.

[0037] For the embodiment in which the lower connecting rod 11 is slidingly connected to the push rod 8, a further optimized setting is that the push rod 8 includes a push rod body 801 and a connecting seat 802 vertically movably installed on the push rod body 801, and the lower connecting rod 11 is slidingly connected to the connecting seat 802.

[0038] exist Figure 1 In the embodiment shown, for the embodiment in which the connecting seat 802 is movably mounted on the push rod body 801 in the vertical direction, more specifically, as shown in FIG. Figure 2 As shown, the push rod body 801 forms a vertically extending mounting plate 19, and the mounting plate 19 is provided with a mounting groove 20. The connecting seat 802 is vertically slidably mounted in the mounting groove 20. A vertically extending lead screw 21 is provided in the mounting groove 20. The lead screw 21 is threadedly engaged with the connecting seat 802, so that the vertical movable installation of the connecting seat 802 can be achieved by rotating the lead screw 21. In an optional embodiment, other methods can be selected for the vertical movable installation of the connecting seat 802, such as providing a through slot in the side wall of the mounting groove 20, and fixing the connecting seat 802 by passing a bolt through the through slot and then screwing it to the connecting seat 802, with the head of the bolt abutting against the mounting plate 19 to achieve the installation of the connecting seat 802.

[0039] Through such an arrangement, the present invention can adjust the vertical sliding cooperation position of the lower connecting rod 11 and the connecting seat 802. When the rotation angle range of the lower connecting rod 11 is consistent, the lateral movement range of the connecting seat 802 can be fine-tuned, and then the amplitude of the lateral movement of the carbon fiber driven by the compensation roller 5 can be fine-tuned.

[0040] Regarding the matching mode between the connecting seat 802 and the lower connecting rod 11, Figure 1 and Figure 2 As shown, the lower connecting rod 11 has a sliding groove, and the connecting seat 802 has a rotating shaft passing through the sliding groove.

[0041] In the embodiment in which the lower connecting rod 11 is provided, a further optimized setting of the present invention is that the telescopic end of the first electrically controlled telescopic rod 6 is provided with a vertical rack 12, and the reversing linkage mechanism includes a first gear 13 meshing with the vertical rack 12, and the first gear 13 is coaxially and detachably mounted with a second gear 14, and the drive shaft 10 is coaxially and detachably mounted with a third gear 15, and the second gear 14 is meshed with the third gear 15.

[0042] like Figure 2 and Figure 3 As shown, the present invention can utilize the step-by-step engagement of the vertical rack 12, the first gear 13, the second gear 14, and the third gear 15 to realize the linkage conversion of the vertical movement of the tension adjustment roller 4 and the lateral movement of the compensation roller 5, so as to further reduce the response time difference in the transmission process.

[0043] Furthermore, the present invention utilizes replaceable second and third gears 14, 15. This allows for adjustment of the correspondence between the vertical movement of the tension adjustment roller 4, the rotation angle of the drive shaft 10, and the lateral movement of the connecting base 802 using second and third gears 14, 15 with different transmission ratios. This allows for greater adjustment of the lateral movement of the connecting base 802 compared to the aforementioned method of vertically adjusting the mounting position of the connecting base 802.

[0044] Among them, for the detachable connection between the second gear 14 and the third gear 15, it is preferred that the second gear 14 can be connected to the first gear 13 by screws or connected to the rotating shaft of the first gear 13 by keys, and the third gear 15 can be connected to the drive shaft 10 by screws or connected to the drive shaft 10 by keys.

[0045] The implementation of the reversing linkage structure is not limited to the above-mentioned method of using the lower connecting rod 11. In an optional embodiment, it can also be as follows Figure 4 In the illustrated arrangement, the reversing linkage mechanism includes a vertical rack 12 and a gear assembly meshing with the vertical rack 12. The vertical rack 12 is connected to the telescopic end of the first electrically controlled telescopic rod 6, and the gear assembly meshes with the push rod 8. This allows the push rod 8 to be directly driven to move laterally via the gear assembly.

[0046] In a preferred embodiment, regarding the manner in which the gear assembly drives the push rod 8 to move laterally, to be more specific, the gear assembly includes a first gear 13 meshing with the vertical rack 12, a second gear 14 coaxially connected to the first gear 13, and a fourth gear meshing with the second gear 14, and the fourth gear meshes with the push rod 8.

[0047] exist Figure 4 In the embodiment shown, a further optimized setting of the present invention is that the push rod 8 includes a push rod body 801 and a transverse rack body 803 which can be raised and lowered on the push rod body 801; the fourth gear includes a gear seat 17 which can be raised and lowered vertically and a fourth gear body 18 which can be detachably mounted on the gear seat 17, and the fourth gear body 18 is engaged with the transverse rack body.

[0048] like Figure 4As shown, the conversion ratio between the vertical movement amplitude of the tension adjustment roller 4 and the lateral movement amplitude of the compensation roller 5 can be adjusted by replacing the fourth gears of different sizes. In order to facilitate the adjustment, a vertically liftable gear seat 17 is provided so that the fourth gears of different sizes can be engaged with the second gear 14, and a liftable transverse rack body 803 is provided so that the transverse rack body 803 can be kept engaged with the fourth gear.

[0049] For the vertical movement of the gear seat 17, in one installation method, a vertical screw 21 mechanism can be set on the frame, and the screw 21 slider of the screw 21 mechanism is used to install the connecting seat 802. For the vertical adjustment method of the horizontal rack body 803, preferably, a screw 16 can be set at the bottom of the horizontal rack body 803, and a through hole for the screw 16 to pass through can be set in the push rod body 801. The screw 16 is screwed on the upper and lower sides of the push rod body 801 and has a nut.

[0050] The arrangement of the first driving member and the second driving member is not limited to the above-mentioned mechanical linkage. In an optional embodiment, the arrangement may be such that the first driving member is arranged as a first electrically-controlled telescopic rod 6 and the second driving member is arranged as a second electrically-controlled telescopic rod.

[0051] In a preferred embodiment, a further optimized configuration of the present invention is that the compensation roller 5 is configured as a stainless steel compensation roller 5 .

Each embodiment focuses on the differences between the other embodiments.
