Description

Technical Field

[0001] This utility model relates to the field of fiber impregnation technology, specifically to a fiber impregnation device. Background Technology

[0002] Impregnation is a crucial step in the fiber winding process, determining the degree of impregnation, fiber strength, and resin content of the wound yarn. The resin content has a significant impact on the performance of the wound product, primarily manifested in the following ways: excessively high resin content reduces product strength and causes severe resin flow during molding and curing; excessively low resin content increases product porosity, leading to decreased tightness, aging resistance, and shear strength. Therefore, ensuring accurate resin content is paramount in the impregnation process.

[0003] Currently, the most common impregnation process involves continuously and parallelly entering a resin bath filled with resin solution for impregnation. The resin bath is often open. After impregnation, excess resin on the fiber bundles drips off during the fiber pulling process, affecting the working environment. Therefore, a fiber impregnation device is proposed.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This invention provides a fiber impregnation device. Excess adhesive in the fiber bundle is squeezed out and returned to the adhesive tank by a guide roller and an extrusion roller. The fiber bundle then passes through a guide groove, which scrapes off excess adhesive from the fiber bundle surface, preventing excessive adhesive dripping after the fiber bundle exits. This avoids excess adhesive dripping onto the external environment and affecting the working conditions. (See also...) Figures 1-4 It includes: a support mechanism 100, an unwinding roller 200, a wire guide mechanism 300, and a drive component 400.

[0032] The support mechanism 100 includes a glue box 110, a pressure roller 120, an unwinding bracket 130, a shaft hole 140, a slide groove 150, a guide groove 160, and a bracket 170. The pressure roller 120 is arranged at the center of the bottom of the inner cavity of the glue box 110. The unwinding bracket 130 is arranged on the left side of the top of the glue box 110. The shaft hole 140 is opened on the right side of the top of the glue box 110. The slide groove 150 is opened on the left side of the shaft hole 140. The guide groove 160 is opened at the top of the right side wall of the glue box 110. The bracket 170 is arranged on the right side wall of the glue box 110.

[0033] The glue box 110 is filled with the glue required for fiber filling, the pressure roller 120 is used to press the fiber into the glue box 110 for conveying, and the bracket 170 is used as... Figure 2 As shown, it is used to provide a support structure.

[0034] The unwinding roller 200 is mounted on the unwinding bracket 130. The unwinding bracket 130 has an unwinding slot 131 at its top. The unwinding roller 200 is connected to the unwinding slot 131 by a damping bearing. When the fiber is pulled, the damping bearing provides resistance, which enables the fiber to be straightened for impregnation.

[0035] The wire guiding mechanism 300 is disposed on the shaft hole 140 and the slide groove 150. The wire guiding mechanism 300 includes a wire guiding roller 310, a slider 320, a pressing roller 330 and a spring 340. The wire guiding roller 310 is rotatably connected to the shaft hole 140, the slider 320 is slidably connected to the slide groove 150, the pressing roller 330 is rotatably connected between the sliders 320, and the spring 340 is connected between the sliders 320 and the slide groove 150.

[0036] Spring 340 provides elastic force, causing extrusion roller 330 to approach guide roller 310.

[0037] The drive component 400 is mounted on the bracket 170. The drive component 400 includes a motor 410 and a drive gear 420. The motor 410 is fixed on the bracket 170, and the drive gear 420 is mounted on the output end of the motor 410.

[0038] The take-up roller 500 is mounted on the bracket 170 and connected to the drive component 400. The take-up roller 500 includes a shaft 510 and a driven gear 520. The front end of the shaft 510 is provided with a driven gear 520 that meshes with the drive gear 420.

[0039] Since the glue cannot be dried before the fibers are wound up (otherwise they would stick together), a drying mechanism 600 is connected to the rear end of the roll 510. The drying mechanism 600 includes a transmission gear 610, a speed-changing pinion 620, a transmission shaft 630, a disc 640, a connecting rod 650, a drive bevel gear 660, a fan shaft 670, a driven bevel gear 680, and an impeller 690. The transmission gear 610 is fixed to the rear end of the roll 510, and the speed-changing pinion 620 is rotatably connected to the bracket 170. Above, the variable speed pinion 620 meshes with the transmission gear 610, the transmission shaft 630 is rotatably connected to the bracket 170, one end of the transmission shaft 630 is provided with a disc 640, the disc 640 and the variable speed pinion 620 are connected by an eccentric shaft and a connecting rod 650, the other end of the transmission shaft 630 is provided with a drive bevel gear 660, the wind shaft 670 is rotatably connected to the bracket 170, the lower end of the wind shaft 670 is provided with a driven bevel gear 680 that meshes with the drive bevel gear 660, and the upper end of the wind shaft 670 is provided with an impeller 690;

[0040] Among them, the roller 510 synchronously drives the transmission gear 610 to rotate, the transmission gear 610 drives the speed-changing pinion 620 to rotate, the speed-changing pinion 620 drives the disc 640 to rotate through the connecting rod 650, the disc 640 drives the drive bevel gear 660 to rotate through the transmission shaft 630, the drive bevel gear 660 meshes and drives the driven bevel gear 680 to rotate, the driven bevel gear 680 drives the impeller 690 to rotate through the wind shaft 670, and the impeller 690 drives the airflow.

[0041] Since the impeller 690 needs to rotate rapidly, the diameter of the transmission gear 610 is larger than that of the variable speed pinion 620, and the diameter of the drive bevel gear 660 is larger than that of the driven bevel gear 680, so as to achieve the speed increase of the large gear driving the small gear.

[0042] To avoid environmental pollution from the open structure, the top of the plastic box 110 is open, and a lid is provided at the opening to cover the top opening of the plastic box 110.

[0043] In practical use, the fiber bundle is drawn from the unwinding roller 200, passes through the bottom of the pressure roller 120, and then exits between the extrusion roller 330 and the guide roller 310. Afterward, the fiber bundle passes through the guide groove 160 and winds onto the take-up roller 500. The motor 410 drives the drive gear 420 to rotate, which in turn drives the take-up roller 500 to take in the fiber, causing the fiber bundle to automatically exit from the glue box 110 after being impregnated with glue. As the fiber bundle exits, the extrusion roller 330 and the guide roller 310 squeeze out excess glue from the fiber bundle, causing it to fall back into the glue box 110. The fiber bundle then passes through the guide groove 160, where the guide groove scrapes off any excess glue from the surface of the fiber bundle. To prevent excessive glue dripping after the fiber bundles emerge, thus avoiding excess glue dripping onto the outside and affecting the working environment, the roller 510 synchronously drives the transmission gear 610 to rotate. The transmission gear 610 drives the variable speed pinion 620 to rotate. The variable speed pinion 620 drives the disc 640 to rotate via the connecting rod 650. The disc 640 drives the drive bevel gear 660 to rotate via the transmission shaft 630. The drive bevel gear 660 meshes with and drives the driven bevel gear 680 to rotate. The driven bevel gear 680 drives the impeller 690 to rotate via the fan shaft 670. The impeller 690 drives the airflow, which blows the airflow onto the glue-impregnated fibers, allowing the glue on the fibers to dry quickly.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
