AI Technical Summary
Basalt fiber is prone to breakage during the chopped strand process. Traditional chopped strand machine equipment lacks sufficient control precision in the yarn conveying process, causing fibers to detach from the yarn rollers and the yarn path to deviate, affecting production continuity and efficiency.
A yarn rack for chopped basalt fiber is designed. By setting multiple layers of plates, yarn guide rods, and perforated yarn guide plates on the yarn rack frame, the yarn is controlled to be drawn out from the inside of the yarn bundle and bypass the yarn guide holes, and finally gathered at the yarn guide frame and sent into the chopped cleaver for cutting, thus achieving effective control over the yarn path.
It reduces the frequency of yarn breakage, improves production efficiency and continuity, and ensures stable yarn delivery.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of basalt fiber technology, and in particular to a yarn rack for chopped basalt fiber. Background Technology
[0002] Basalt fiber is widely used in composite materials, construction, filtration and other fields due to its high strength and high temperature resistance. Before use, basalt fiber needs to be placed on a yarn rack and then cut into the required length using a chopped strand machine.
[0003] Basalt fiber filaments are brittle and lack flexibility, making them prone to breakage during skewing. This breakage frequency increases significantly at higher yarn speeds, negatively impacting production continuity and efficiency.
[0004] Traditional chopped strand registries lack sufficient control precision in the yarn delivery process, easily leading to technical problems such as fiber detachment from the yarn rollers and yarn path deviation. Therefore, there is an urgent need for a new type of basalt fiber chopped strand registry that can reduce yarn breakage frequency and prevent path deviation. Summary of the Invention
[0005] The purpose of this invention is to provide a yarn frame for chopped basalt fiber. By setting multiple layers on the yarn frame and setting yarn bundles on the layers, the yarn is drawn out from the inside of the yarn bundles, passes around the yarn guide rod, passes through the yarn guide holes on the perforated yarn guide plate, and finally gathers at the yarn guide frame and is sent into the chopped slit machine for cutting. This achieves effective control over the yarn path, reduces the frequency of yarn breakage, and improves production efficiency.
[0006] To achieve the above objectives, this utility model provides a yarn rack for chopped basalt fiber, including a yarn rack frame and a yarn guide frame. The yarn rack frame is provided with a yarn guide rod, a layer plate, and a perforated yarn guide plate. A yarn ball is provided on the layer plate. The yarn guide rod is located above the yarn ball. The yarn guide frame is located in front of the perforated yarn guide plate.
[0007] Preferably, the yarn frame includes uprights and crossbeams, with two uprights and the crossbeams positioned between the two uprights.
[0008] Preferably, the perforated yarn guide plate is disposed on the side of the column, the layer plate is disposed on the upper end of the crossbeam, and the yarn guide rod is disposed on the lower end of the crossbeam.
[0009] Preferably, the yarn ball contains yarn, and the yarn ends are provided on the inner side of the yarn ball.
[0010] Preferably, the yarn guide frame includes an outer frame, an inner frame, a yarn guide plate, and bolts, with the inner frame disposed on the outer frame and the yarn guide plate disposed on the inner frame.
[0011] Preferably, the yarn guide plate of the yarn guide frame is provided with the yarn guide hole, and the side of the outer frame is provided with fastening holes.
[0012] Therefore, this utility model adopts the above-mentioned basalt fiber chopped yarn frame. By setting multiple layers on the yarn frame frame and setting yarn balls on the layers, the yarn is drawn out from the inside of the yarn balls, passes around the yarn guide rod in sequence, passes through the yarn guide holes on the multi-hole yarn guide plate, and finally gathers at the yarn guide frame and is sent into the chopped yarn machine for cutting. This realizes effective control of the yarn path, reduces the yarn breakage frequency, and improves production efficiency.

[0024] Example 1
[0025] This utility model provides a yarn frame for chopped basalt fibers, such as... Figures 1-3 As shown, the device includes a yarn frame 1 and a yarn guide frame 5. In this embodiment, the yarn frame 1 and the yarn guide frame 5 are 1.5 meters to 2 meters apart. The yarn frame 1 includes columns 9 and crossbeams 7. There are two columns 9 and several crossbeams 7 are arranged between the two columns 9. Each crossbeam 7 has a shelf 8 at its upper end. Except for the top shelf 8, each shelf 8 has several yarn balls 2. Each shelf 8 has a perforated yarn guide plate 4 at one side of a column 9. The perforated yarn guide plate 4 has several yarn guide holes.
[0026] The yarn guide rod 3 is located at the lower end of the crossbeam 7 and directly above the yarn bundle 2. The structure of the yarn guide rod 3 is as follows: Figure 4 As shown, the yarn ball 2 is composed of yarn 6, and the yarn ball 2 has yarn ends on the inner side.
[0027] like Figure 5 Figure 6 As shown, the yarn guide frame 5 includes an outer frame 501, an inner frame 502, a yarn guide plate 503, and bolts 504. The outer frame 501 has several fastening holes 505 on its side. The bolts 504 pass through the fastening holes 505 to fix the inner frame 502 to the outer frame 501. The yarn guide plate 503 is also fixed to the inner frame 502 by bolts 504. The yarn guide plate 503 has several yarn guiding holes. By changing the fastening holes 505 to which the bolts 504 are fixed, the fixing height of the inner frame 502 on the outer frame 501 can be adjusted, thereby further adjusting the height of the yarn guide plate 503.
[0028] The basalt fiber chopped strand frame described in this embodiment operates as follows:
[0029] Adjust the yarn guide plate 503 on the yarn guide frame 5 to a suitable height, pull out the ends of the yarns 6 in all the yarn balls 2 and pass them over the yarn guide rod 3 above them, and then pass the yarns 6 out through the multi-hole yarn guide plate 4 on the side, with each yarn 6 passing through a different yarn guide hole.
[0030] The yarns 6 that pass through the multi-layered perforated yarn guide plates 4 converge on the yarn guide plate 503 of the yarn guide frame. Each yarn 6 passes through a different yarn guide hole. After passing through the yarn guide plate 503, the yarn 6 is cut to the required length by the short cutting machine.
[0031] Therefore, this utility model adopts the above-mentioned basalt fiber chopped yarn frame. By setting multiple layers on the yarn frame frame and setting yarn balls on the layers, the yarn is drawn out from the inside of the yarn balls, passes around the yarn guide rod in sequence, passes through the yarn guide holes on the multi-hole yarn guide plate, and finally gathers at the yarn guide frame and is sent into the chopped yarn machine for cutting. This realizes effective control of the yarn path, reduces the yarn breakage frequency, and improves production efficiency.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
