Description

Technical Field

[0001] This utility model relates to the field of fiber production, and more specifically to a yarn separating device for pultrusion molding. Background Technology

[0002] As is well known, proper fiber arrangement is crucial for product quality in pultrusion processes. Currently, existing technologies lack a tooling method capable of precisely achieving fiber layering. In most cases, the fibers are arranged very haphazardly upon entering the impregnation tank, leading to uneven impregnation and consequently affecting the mechanical properties and appearance quality of the pultruded products. For example, some simple fiber guiding devices cannot effectively control fiber layering, resulting in localized areas with too many or too few fibers during impregnation, reducing product consistency and reliability. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a yarn separating device for pultrusion molding, which can accurately realize the layered arrangement of fibers.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a yarn separating device for pultrusion molding, which is vertically provided with two side supports on the left and right. The side supports are characterized in that the bottom ends of the side supports are machined with anchor bolt holes, the side supports are triangular structures, and the side supports are provided with step-shaped hooks on the hypotenuses. The curled parts of the hooks are machined with grooves. A layered yarn plate is provided between the left and right side supports. Two rows of yarn holes are evenly machined on the layered yarn plate. Ceramic smooth ring-shaped guides are pasted at the yarn holes. Ear plates are provided at both ends of the layered yarn plate and are fitted into the grooves.

[0005] The beneficial effects of this invention are that it enables precise layering of fibers, improves the uniformity of fiber impregnation, and thus enhances the stability of pultruded products. Attached Figure Description

[0012] In the figure, this utility model has two vertical side supports 7, one on the left and one on the right. Anchor bolt holes 2 are machined at both ends of the bottom of each side support 7. The two side supports 7 are installed in designated positions using anchor bolts, anchor bolts, or other suitable fixing methods to ensure the levelness and stability of the supports. Each side support 7 has a triangular structure. Hooks 5 are evenly distributed in a stepped pattern on the hypotenuse of each side support 7. The curled parts of the hooks 5 are machined with grooves 6. A layered yarn plate 1 is provided between the two side supports 7. Two rows of yarn holes are evenly machined on the layered yarn plate 1. Ear plates 4 are provided at both ends of the layered yarn plate 1, and the ear plates 4 are fitted into the grooves 6.

[0013] The overall structure of this utility model includes two side supports 7 on the left and right sides and six layered yarn plates 1. The number of layered yarn plates 1 can be adjusted according to different yarn arrangement methods. The two side supports 7 on the left and right sides are made of high-strength alloy material, which has good rigidity and stability, and is used to make the entire tooling structure.

[0014] Six layered yarn plates 1 are placed parallel to each other between the left and right side supports 7. Each layered yarn plate 7 has multiple evenly distributed yarn holes 3. The diameter and shape of the yarn holes 3 are customized according to the type and specifications of the fibers to ensure that the fibers can pass through smoothly and maintain an orderly arrangement. Each yarn hole 3 needs to be fitted with a smooth ceramic annular guide to ensure that the yarn hole is smooth and that the fibers do not wear out when passing through. The layered yarn plates 1 are connected to the left and right side supports 7 by a detachable structure to ensure that the layered yarn plates 1 will not be affected by the traction force generated by the fiber's advance and will not fall off. At the same time, it is convenient to adjust the number and spacing of the layered yarn plates 1 according to actual production needs.

[0015] In addition, this utility model can also be equipped with a height adjustment mechanism and an angle adjustment mechanism on the left and right side supports 7 as needed. The height adjustment mechanism adopts a screw and nut transmission structure, which can accurately adjust the vertical height of the layered yarn board; the angle adjustment structure adopts a worm gear transmission structure, which can realize the fine adjustment of the layered yarn board within a certain angle range, thereby meeting the requirements of different pultrusion processes for fiber arrangement angle.

[0016] By strategically positioning the layered yarn board and its openings, fibers can be precisely layered, ensuring a neat and orderly arrangement as they enter the impregnation tank, thus guaranteeing uniform impregnation. This precise layering allows for even impregnation, effectively preventing issues such as inconsistent product strength and appearance defects caused by uneven impregnation, thereby improving overall product quality. The detachable connection of the layered yarn board and the adjustment mechanism allow this fixture to adapt to different fiber types and pultrusion processes, offering strong versatility and flexibility, and reducing equipment replacement costs for businesses.
