Description
Technical Field
[0001] This utility model relates to the field of fiber forming and processing equipment technology, and in particular to an impregnation device for long filament fibers. Background Technology
[0002] Filament fiber impregnation refers to the process of liquid (such as resin, coating agent, oil, etc.) penetrating, spreading and adhering to the surface and internal microstructure of filament fibers. It is a key step in fiber surface modification, composite material preparation and textile processing. However, traditional filament fiber impregnation devices cannot adapt to different numbers and types of fibers, and therefore cannot guarantee that the impregnation of filament fibers will achieve a uniform effect.
[0003] To address the above issues, patent document CN219490393U discloses a filament fiber impregnation device, including a glue tank with a guide device inside to guide the filament fibers through. The guide device includes a guide roller and a lower comb disposed on the side of the guide roller shaft. An upper comb is disposed above the lower comb, with the teeth of the lower comb and the upper comb arranged in an interlocking, staggered configuration. The upper comb is slidably positioned within the glue tank via an adjustment component to adjust the distance between the upper and lower combs. Under the action of the adjustment component, the extension depth of the upper comb teeth to the gap between adjacent teeth of the lower comb is adjusted to accommodate filament fibers of different specifications. Since the lower comb is located at the outlet end of the glue tank, excess sizing agent can be scraped off as the filament fibers pass through, resulting in more uniform impregnation of the sizing agent onto the filament fibers.
[0004] However, in existing filament impregnation devices, the structure for adjusting the height of the guide roller is located inside the glue tank, making the adjustment of the guide roller height inconvenient. Utility Model Content

Detailed Implementation
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the impregnation device for filament fibers. Figure 2 This is a schematic diagram of the regulating mechanism. Figure 3 yes Figure 2 Enlarged view of the local structure at point A. Figure 4 This is a schematic diagram of the sliding seat.
[0021] This utility model provides a device for impregnating filament fibers, comprising a glue tank 101, a fixing frame 102, a sliding plate 103, a lower yarn comb 104, an upper yarn comb 105, a guide roller 106, and an adjustment mechanism. The adjustment mechanism includes two sliding guide rails 107, a sliding frame, a mounting frame 108, a threaded rod 109, a rotating handwheel 110, and a connecting bearing 111. The sliding frame includes a connecting plate 112, two side plates 113, and two sliding seats 114. This solution solves the problem in existing filament fiber impregnation devices where the structure for adjusting the height of the guide roller 106 is located inside the glue tank 101, making the height adjustment of the guide roller 106 inconvenient. It is understood that the aforementioned solution can be applied to the structure of a filament fiber impregnation device.
[0022] In this specific embodiment, one end of the glue tank 101 is provided with a plurality of thread-passing holes 115, and the fixing frame 102 is fixedly disposed inside the other end of the glue tank 101. The bottom of the fixing frame 102 is fixedly disposed with the lower yarn comb 104, and the top of the fixing frame 102 is slidably disposed with the sliding plate 103 (the sliding plate 103 is driven by an adjustment component disposed at the top of the fixing frame 102; the structure of the adjustment component is disclosed in the prior art, so it is not described in detail in this technical solution). The bottom of the sliding plate 103 is provided with the upper yarn comb 105, and the lower yarn comb 104 is disposed with the lower yarn comb 105. The comb teeth of the upper comb 105 are interlocked and staggered. The guide roller 106 is provided inside the glue trough 101. The depth of the gap between adjacent comb teeth of the upper comb 105 and the lower comb 104 is adjusted to adapt to filament fibers of different specifications. Since the lower comb 104 is located at the discharge end of the glue trough 101, excess sizing agent can be scraped off when the filament fibers pass through, and the sizing agent can be more evenly applied to the filament fibers. The guide roller 106 guides the filament fibers in contact.
[0023] The glue tank 101 has sliding guide rails 107 on both sides inside, and a sliding frame is slidably arranged between the two sliding guide rails 107. The guide roller 106 is mounted on the sliding frame. The mounting frame 108 is mounted on the top of the glue tank 101 and is located above the sliding frame. The mounting frame 108 is threadedly connected to the middle of the mounting frame 108 with a threaded rod 109. The end of the threaded rod 109 near the sliding frame is connected to the sliding frame through the connecting bearing 111. The top of the threaded rod 109 is provided with a rotating handwheel. 110. When it is necessary to adjust the height of the guide roller 106 in the glue tank 101 according to the actual situation, simply rotate the rotating handwheel 110 to drive the threaded rod 109 to rotate. With the cooperation of the connecting bearing 111, the sliding frame is driven to slide between the two sliding guide rails 107, thereby completing the adjustment of the height of the guide roller 106 in the glue tank 101. With the above structure, when adjusting the height of the guide roller 106, it is only necessary to operate the rotating handwheel 110 outside the glue tank 101, which makes the operation more convenient.
[0024] Secondly, the two ends of the connecting plate 112 are fixedly provided with the side plates 113, and each side plate 113 is provided with a sliding seat 114. Each sliding seat 114 is slidably connected to the corresponding sliding guide rail 107. By setting two sliding seats 114, the sliding frame can slide linearly between the two sliding guide rails 107, making the structure more stable when the sliding frame slides.
[0025] Meanwhile, each of the sliding guide rails 107 is provided with a fixing wing plate 116 on the side near the inner wall of the glue groove 101. The fixing wing plate 116 is connected to the inner wall of the glue groove 101. The installation of the sliding guide rail 107 is completed by setting the fixing wing plate 116.
[0026] In addition, each of the sliding seats 114 has mounting holes 117 on both sides of the side closest to the corresponding sliding guide rail 107. The mounting holes 117 are equipped with balls 118, which fit against the end face of the corresponding sliding guide rail 107. The arrangement of the balls 118 makes the sliding seat 114 slide more smoothly on the sliding guide rail 107.
[0027] Furthermore, a fixing head 119 is provided at the top of the threaded rod 109, and an insert head 120 is provided at the bottom of the threaded rod 109. The rotating handwheel 110 is located outside the fixing head 119, and the insert head 120 is embedded inside the connecting bearing 111. The fixing head 119 facilitates the installation of the rotating handwheel 110, and the insert head 120 facilitates the connection between the threaded rod 109 and the connecting bearing 111.
[0028] When using the filament fiber impregnation device of this invention, the depth of the extension of the comb teeth of the upper comb 105 into the gap between adjacent comb teeth of the lower comb 104 is adjusted to adapt to filament fibers of different specifications. Since the lower comb 104 is located at the discharge end of the adhesive trough 101, excess impregnating agent can be scraped off as the filament fibers pass through, resulting in more uniform impregnation of the filament fibers. Furthermore, the guide roller 106 guides the filament fibers through contact. Depending on the actual situation, adjustments can be made as needed. To adjust the height of the guide roller 106 within the glue tank 101, simply rotate the handwheel 110, which rotates the threaded rod 109. With the cooperation of the connecting bearing 111, the sliding frame slides between the two sliding guide rails 107, thereby adjusting the height of the guide roller 106 within the glue tank 101. With this structure, adjusting the height of the guide roller 106 only requires operating the handwheel 110 from outside the glue tank 101, making the operation more convenient.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
