Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yarn guiding devices, specifically a pultruded preformed yarn guiding device. Background Technology
[0002] During the processing of fiberglass profiles, the yarns need to be impregnated with resin to improve the quality of fiberglass profile pultrusion production. Furthermore, the yarns must not intertwine during the impregnation process.
[0003] When the yarn guiding device is in use, because the yarn threading holes on it are generated before the device leaves the factory, if the number of yarns is greater than the number of yarn threading holes, the excess yarns cannot be guided, making the yarn guiding operation impossible. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A pultruded preform yarn guiding device includes a yarn guiding mechanism and a backup mechanism. The yarn guiding mechanism includes a yarn guiding plate and multiple threading holes 1 opened on the yarn guiding plate. The backup mechanism includes multiple folding plates connected to the rear sidewall of the yarn guiding plate, a backup plate movably installed between two folding plates via a rotating shaft, multiple threading holes 2 opened on the backup plate, and an insert detachably connected between the folding plates and the rotating shaft.
[0007] By adopting the above technical solution, after the yarn guide plate is installed on the external pultrusion molding equipment, the yarn first passes through the first threading hole on the yarn guide plate. When the number of yarns exceeds the number of threading holes one, the two upper inserts can be pulled out, the corresponding backup plates can be adjusted to the horizontal working position, and the inserts can be reinserted and fixed. At this time, the excess yarn can pass through the second threading hole on the backup plate. If the number of threading holes two is still insufficient, the above steps can be repeated to expand using the lower backup plate. This double backup plate design effectively meets the needs of guiding multiple yarns and ensures the smooth operation of the yarn guiding operation.
[0008] In a preferred embodiment, the present invention can be further configured such that: the yarn guide plate has multiple threaded holes arranged in a matrix.
[0009] In a preferred embodiment, the present invention can be further configured such that: slots are provided on both the front and rear sides of the insert, and the slots are set as long rectangles.
[0010] In a preferred embodiment, this utility model can be further configured as follows: multiple folding plates are arranged in pairs, forming two groups, with the two groups of folding plates being laterally symmetrical about the horizontal center plane of the yarn guide plate, and two backup plates located inside the two groups of folding plates respectively.
[0011] In a preferred embodiment, the present invention can be further configured such that: multiple threading holes are equally spaced and arranged in a row, wherein the diameter of the threading hole one is equal to the diameter of the threading hole two.
[0012] In a preferred embodiment, the present invention can be further configured such that: the multiple threading holes 2 on the backup plate are equally spaced and arranged in a row, and the multiple threading holes 1 and multiple threading holes 2 are staggered.
[0013] In a preferred embodiment, the present invention can be further configured such that the insert is shaped like a "[" and is made of metal.
[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0015] 1. In this utility model, after the yarn guide plate is installed on the external pultrusion molding equipment, the yarn first passes through the first threading hole on the yarn guide plate. When the number of yarns exceeds the number of threading holes one, the two upper inserts can be pulled out, the corresponding backup plates can be adjusted to the horizontal working position, and the inserts can be reinserted and fixed. At this time, the excess yarn can pass through the second threading hole on the backup plate. If the number of threading holes two is still insufficient, the above steps can be repeated to expand using the lower backup plate. This double backup plate design effectively meets the needs of guiding multiple yarns and ensures the smooth progress of the yarn guiding operation.
[0016] 2. In this utility model, the first threading hole and the second threading hole are arranged in an alternating manner, so that the yarns passing through them can move separately and avoid mutual interference, ensuring that the yarns can be stably impregnated with resin, achieving complete and uniform impregnation of the fiber reinforcement, and ensuring that the final composite material product has high strength, high rigidity, high durability and consistent performance.

[0030] Example 1:
[0031] Combination Figure 1-5 As shown, the present invention provides a pultrusion preform yarn guiding device, including a yarn guiding mechanism 100 and a spare mechanism 200. The yarn guiding mechanism 100 includes a yarn guiding plate 110 and a plurality of threading holes 120 opened on the yarn guiding plate 110.
[0032] The backup mechanism 200 includes multiple folding plates 210 connected to the rear side wall of the yarn guide plate 110, a backup plate 230 movably mounted between two folding plates 210 via a rotating shaft 220, multiple threading holes 240 opened on the backup plate 230, and an insert 250 detachably connected between the folding plates 210 and the rotating shaft 220.
[0033] Furthermore, multiple folding plates 210 are arranged in pairs, forming two groups. The two groups of folding plates 210 are laterally symmetrical about the horizontal center plane of the yarn guide plate 110. Two backup plates 230 are located inside the two groups of folding plates 210 respectively. The layout design of the folding plates 210 can guide the placement of the two backup plates 230, providing conditions for the separate movement of multiple yarns.
[0034] Furthermore, multiple threading holes 120 are arranged in a row at equal intervals, and the diameter of threading hole 120 is equal to the diameter of threading hole 240. The size design of threading hole 120 and threading hole 240, to a certain extent, ensures the aesthetic appearance of the device structure.
[0035] Furthermore, the multiple threading holes 240 on the backup plate 230 are equally spaced and arranged in a row, and the multiple threading holes 120 and multiple threading holes 240 are staggered. This layout design ensures that the yarns are separated from each other.
[0036] Furthermore, the insert 250 is configured in the shape of "[" and is made of metal. The metal insert 250 can firmly fix the horizontally placed backup plate 230.
[0037] Example 2:
[0038] Combination Figure 1-3 As shown, based on Embodiment 1, the yarn guide plate 110 is provided with a plurality of threaded holes 300, which are arranged in a matrix. The threaded holes 300 facilitate the connection of the yarn guide plate 110 with external pultrusion molding equipment.
[0039] Example 3:
[0040] Combination Figure 5 As shown in the above embodiment, the insert 250 has slots 400 on both the front and rear sides. The slots 400 are set as long rectangles. The slots 400 can improve the grip of the operator when inserting and removing the insert 250 and improve the comfort of using the device.
[0041] The working principle and usage process of this utility model are as follows: The yarn guide plate 110 is installed on the external pultrusion molding equipment through multiple threaded holes 300. The yarn first passes through the threading hole 120 on the yarn guide plate 110. When the number of yarns exceeds the number of threading holes 120, the two upper inserts 250 can be pulled out. After adjusting the corresponding backup plate 230 to the horizontal working position, the inserts 250 are reinserted and fixed. At this time, the excess yarn can pass through the threading hole 240 on the backup plate 230. If the number of threading holes 240 is still insufficient, the above steps can be repeated to expand using the lower backup plate 230. This double backup plate 230 design effectively meets the needs of guiding multiple yarns. In addition, since the threading holes 120 and threading holes 240 are arranged in an alternating manner, it can meet the requirements of separating different yarns and avoiding mutual interference.
[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
