Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a warp yarn lifting device for electronic-grade glass fiber ultra-thin cloth. Background Art
[0002] From the perspective of technology, the warp stop frame of the loom is an important part that controls the warp position line. From the perspective of equipment, the warp stop frame can detect the break of the warp yarn and stop the machine in time. However, due to the change of fabric structure, the vibration of the warp stop frame increases, and the technology and equipment cannot effectively reduce the vibration. Because the increase in vibration will greatly increase the number of false warp breaks and warp breaks without stopping.
[0003] With the advancement of science and technology, terminal electronic devices are becoming more and more "thin, light, short and small". As a definite direction of sustainable development, the internal electronic components of terminal electronic devices are also becoming more and more "thin, light, short and small". Electronic cloth is an indispensable material for the production of copper clad laminates and a special basic material for the production of printed circuit boards. In recent years, it has also been developing in the direction of becoming thinner and thinner. However, the thinner the electronic grade glass fiber cloth is, the more problems will occur in the production process, and the more demanding the production conditions will be.
[0004] like Figure 4-Figure 6 As shown, in general, in order to take compatibility into consideration, the warp stop frame of the loom uses a warp stop seat with a thicker / larger cross-section. The warp stop seat is 1490mm long and 20mm wide. There are two warp stop rods on one warp stop seat, and the warp yarn width of 1230mm is in full contact with the warp stop seat. The contact area is relatively large and can withstand heavier thick cloth warp yarns.
[0005] When used for extremely thin cloth, since the warp yarn is relatively light and thin, it will swing up and down during the weaving process and rub against the warp stop seat, causing the warp yarn to easily produce small hairiness and broken threads, affecting the quality of the cloth. Utility Model Content
[0006] The purpose of the utility model is to provide a warp yarn lifting device for electronic grade glass fiber ultra-thin cloth, which can reduce abnormal phenomena such as broken yarns and hairiness on the cloth surface caused by the friction of the warp yarns by the warp stop seat during the weaving process of the ultra-thin cloth;
[0007] The utility model provides a warp yarn lifting device for electronic grade glass fiber ultra-thin cloth, comprising a cylindrical warp stop rod, which is installed on a warp stop seat, the warp yarn passes over the cylindrical warp stop rod, the two ends of the cylindrical warp stop rod are flush, and the space between the two ends is bent downward.
[0008] Furthermore, the curved trajectory of the cylindrical warp stop bar is an arc.
[0009] Furthermore, a plurality of the cylindrical warp stop bars are installed in parallel on the warp stop seat.
[0010] Furthermore, a plurality of the cylindrical warp stop bars are arranged at intervals.
[0011] Furthermore, the number of the cylindrical warp drop bars is three.
[0012] Furthermore, the diameter of the cylindrical warp drop bar is 4 mm.
[0013] Furthermore, the cylindrical warp stop bar is made of stainless steel round steel.
[0014] The technical solution of the utility model removes the warp stop seat and uses a cylindrical warp stop rod that bends downward between the two ends, so that the warp yarn only contacts the two ends of the cylindrical warp stop rod, and the contact surface between the warp yarn and the cylindrical warp stop rod is approximately 1 mm at both ends, thereby reducing the possibility of full contact friction between the warp yarn and the warp stop seat, reducing the broken silk and abnormal hairiness of the cloth surface during the weaving process of extremely thin cloth, reducing the cutting of cloth due to broken silk and abnormal hairiness, thereby reducing the loss of cloth cutting, improving production efficiency, improving product quality, reducing production costs, reducing rework caused by work quality, and improving economic benefits.

[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0027] Example 1
[0028] like Figure 1-Figure 3 As shown, the utility model provides a warp yarn lifting device for electronic-grade glass fiber ultra-thin cloth, including a cylindrical warp stop rod 2, the cylindrical warp stop rod 2 is installed on a warp stop seat 1, the warp yarn 3 passes over the cylindrical warp stop rod 2, the two ends of the cylindrical warp stop rod 2 are flush, and the two ends are bent downward.
[0029] Specifically, the yarn on the disc head 4 is released after unwinding, and the tension is adjusted by the back beam roller 5, and then reaches the warp stop seat 1. This process is a conventional technology in the textile industry and will not be repeated. The utility model mainly improves the warp stop seat 1.
[0030] The utility model adopts a cylindrical warp stop rod 2, so the contact area between the warp yarn 3 and the warp stop seat 1 is small (it can be understood that the warp yarn 3 is in tangential contact with the top of the cylindrical warp stop rod 2), so that the warp yarn 3 has fewer adverse conditions such as hairiness and broken yarns due to friction, etc., which effectively improves the quality of the cloth surface.
[0031] At the same time, in the utility model, the structure of the cylindrical warp stop bar 2 is a structure with both ends flush and a downward bend between the two ends. Since the warp yarn 3 of the ultra-thin cloth is relatively light and thin, the warp yarn 3 will only contact the two ends of the cylindrical warp stop bar 2 when it swings slightly (it will only contact the cylindrical warp stop bar 2 when the amplitude of the up and down swing is large, so the cylindrical warp stop bar 2 will not lose the function of supporting the warp yarn 3), and the contact surface between the warp yarn 3 and the cylindrical warp stop bar 2 is reduced by 1mm at both ends, and the contact area of the three cylindrical warp stop bars 2 is only about 6mm in total, thereby significantly reducing the possibility of full contact friction between the warp yarn 3 and the warp stop seat 1, and reducing the cloth surface breakage and abnormal hairiness during the weaving process of ultra-thin cloth.
[0032] Example 2
[0033] like Figure 1-Figure 3 As shown, the curved track of the cylindrical warp stop bar 2 is an arc. A plurality of cylindrical warp stop bars 2 are installed in parallel on the warp stop seat 1. A plurality of cylindrical warp stop bars 2 are arranged at intervals. The number of cylindrical warp stop bars 2 is three. The diameter of the cylindrical warp stop bar 2 is 4 mm. The cylindrical warp stop bar 2 is a stainless steel round steel.
[0034] Specifically, the bending trajectory of the cylindrical warp stop bar 2 is a curve with the same curvature, and the middle part is the lowest point of the bending. Multiple cylindrical warp stop bars 2 are arranged in parallel and spaced apart to hold up the warp yarn 3. The cylindrical warp stop bar 2 is a stainless steel round steel with a diameter of 4 mm and a length of 1490 mm. There are three cylindrical warp stop bars 2 on a warp stop frame, and the warp yarn 3 is only in contact with the stainless steel round steel by 1 mm on each side. In this way, when the width of the warp yarn 3 is 1230 mm, the width of the contact with the three stainless steel round steels is only about 6 mm, which greatly reduces the contact area between the warp yarn 3 and the warp stop seat 1, thereby reducing the generation of abnormal small hairiness and broken yarns.
[0035] Working mode and principle of this utility model:
[0036] The two ends of the cylindrical warp stop rod 2 are bent downward so that the warp yarn 3 only contacts the two ends of the cylindrical warp stop rod 2. The contact surface between the warp yarn 3 and the cylindrical warp stop rod 2 is approximately 1 mm on both ends, and the width of contact with the three parallel cylindrical warp stop rods 2 is only about 6 mm. This greatly reduces the contact area between the warp yarn 3 and the warp stop seat 1, thereby reducing the occurrence of abnormal small hairiness and broken silk.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
