Technical Field

[0001] The utility model relates to the technical field of insulating core rod production, in particular to a device for solving the problem of yarn stringing at a warehouse opening of an injected insulating core rod. Background Art

[0002] The main raw materials for the production of insulating core rods are glass fiber, epoxy resin, and curing agent. Glass fiber is mainly made of twisted yarn. Since the produced glass fiber yarn bundles will inevitably have inconsistent lengths and yarn hairiness, the yarn bundles in the middle of different yarn threading holes will be entangled together due to hairiness and inconsistent lengths during the twisting process of the injection process core rod production, resulting in blockage of the yarn threading holes, forcing the line and production to stop, seriously affecting production efficiency. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a device for solving the problem of yarn stringing when an injection insulating core rod enters a bin.

[0004] The purpose of the utility model is achieved through the following technical solutions: a device for solving the problem of yarn stringing when an injection insulating core rod enters a warehouse, comprising a plurality of yarn guide porcelain tubes, the yarn guide porcelain tubes are connected in series as a group, at least one separator ring is arranged on each yarn guide porcelain tube, the separator ring is sleeved outside the yarn guide porcelain tube, and the yarn guide porcelain tube is made of ceramic.

[0005] Furthermore, the inner diameter of the yarn guide ceramic tube gradually decreases from the feed inlet to the discharge outlet.

[0006] Furthermore, the discharge port of the yarn guide porcelain tube is provided with a connecting ring, the connecting ring is a trumpet-shaped structure, the connecting ring is coaxially arranged with the yarn guide porcelain tube, and the small-mouth end of the connecting ring is fixedly connected to the discharge port of the yarn guide porcelain tube.

[0007] Furthermore, a plurality of protrusions are provided at the large-mouthed end of the connecting ring, the protrusions are fixedly connected to the connecting ring, and the protrusions are horizontally spaced on the outer edge of the connecting ring.

[0008] The utility model has the following advantages: by arranging a plurality of yarn guide porcelain tubes and separation rings in series, the problem of yarn bundles in the middle of different yarn threading holes being entangled due to hairiness and inconsistent lengths is avoided, so that the number of shutdowns caused by the yarn bundle entanglement problem has been reduced from the original 3-5 times / day to 10-15 days / times, thereby greatly improving production efficiency.

[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0015] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] Embodiment 1, as Figure 1 , Figure 2 As shown, a device for solving the problem of yarn threading when an injection insulating core rod enters a bin, comprises a plurality of yarn guide porcelain tubes 1, each yarn guide porcelain tube 1 is provided with a separator ring 2, the separator ring 2 is sleeved outside the yarn guide porcelain tube 1, the separator ring 2 and the yarn guide porcelain tube 2 are integrally connected, the yarn guide porcelain tube 1 and the separator ring 2 are both made of ceramic, three yarn guide porcelain tubes 1 are connected together end to end to form a group, a yarn threading PP plate 5 is installed at one end of the dipping bin, a plurality of openings for yarn to pass through are provided at intervals on the yarn threading PP plate 5, each opening corresponds to a group of yarn guide porcelain tubes 1.

[0017] Embodiment 2, as Figure 3As shown, a device for solving the problem of yarn stringing when an injection insulating core rod enters a warehouse port comprises a plurality of yarn guide porcelain tubes 1, each yarn guide porcelain tube 1 is provided with a separation ring 2, the separation ring 2 is sleeved on the leftmost end of the yarn guide porcelain tube 1 and is integrally connected thereto, the inner diameter of the yarn guide porcelain tube 1 gradually decreases from the feed port to the discharge port, a connecting ring 3 is provided at the discharge port of the yarn guide porcelain tube 1, the connecting ring 3 is a trumpet-shaped structure, the connecting ring 3 and the yarn guide porcelain tube are coaxially arranged, the small end of the connecting ring 3 is integrally fixedly connected to the discharge port of the yarn guide porcelain tube 1, a plurality of protrusions 4 are installed on the outer edge of the large end of the connecting ring 3, the protrusions 4 are horizontally spaced on the outer edge of the connecting ring 3, the protrusions 4 are hemispherical, the protrusions 4 are integrally fixedly connected to the connecting ring 3, the yarn guide porcelain tubes 1 are connected head to tail, that is, the protrusions 4 at the tail of the first yarn guide porcelain tube 1 contact the separation ring 2 at the head of the second yarn guide porcelain tube 1.

[0018] The working principle of the utility model is as follows: the existing glass fiber yarn bundles directly enter the dipping chamber through the openings on the yarn threading PP plate. Before being combined and passed through the openings, each group of yarns will spread out and there is a risk of entanglement. By installing the yarn guide porcelain tube on the yarn bundle, the distance between the yarn bundles is enlarged. At the same time, the existence of the separation ring can further prevent the yarn bundles from getting close, increase the distance between the yarn bundles, and greatly reduce the risk of entanglement; each group of yarn guide porcelain tubes is multiple and the two are not fixedly connected, so that the yarn guide porcelain tubes can adjust the angle in real time according to the yarn position; the yarn guide porcelain tubes are made of ceramic material, which can avoid the problem of yarn scraping; a trumpet-shaped connecting ring is installed at the tail of the yarn guide porcelain tube, which can enlarge the distance between the contact surface between adjacent yarn guide porcelain tubes and the yarn bundle, and avoid the problem of yarn hairiness being clamped between adjacent yarn guide porcelain tubes. At the same time, the hemispherical convex points set make the surface-to-surface connection between adjacent yarn guide porcelain tubes become point-to-point connection, further reducing the occurrence of yarn clamping.

[0019] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
