[0025] Traditional glass fiber tubes need to go through the following processes during production: yarn feeding, weaving, tube forming, and sizing. During the stretching and weaving processes, the glass fibers may break, resulting in burrs. These burrs will cause poor quality after the subsequent gluing of the glass fiber tubes, and the weaving and tube forming processes restrict the production efficiency of the products due to the limitations of equipment capabilities. In view of this situation, a glass fiber tube forming device 100 is provided.

[0026] Please refer to Figure 1, the glass fiber tube forming device 100 provided by the present utility model includes a sizing rod core 10 and a spinning mechanism. The spinning mechanism has a spinning nozzle 20, and the spinning nozzle 20 is provided with a nozzle orifice for ejecting molten glass liquid to form a glass liquid stream. The spinning nozzle 20 rotates around the sizing rod core 10 to directly form the ejected glass liquid stream on the sizing rod core 10 to form a glass fiber tube.

[0027] It can be understood that the spinning mechanism includes devices such as a glass melting device, a metering pump, and a spinning head assembly. The spinning head assembly is a set of components that the spinning melt finally passes through. The functions of the spinning assembly are as follows: First, filter the molten glass liquid to remove impurities and gel particles that may be entrained in the melt to prevent clogging of the spinning nozzle; second, enable the melt to be fully mixed to prevent viscosity differences in the melt; third, evenly distribute the melt to the nozzle orifice of each spinning nozzle 20 to form a glass liquid stream. A gas jet is applied at the nozzle orifice of the spinning nozzle 20 to thin and break the glass liquid stream into discrete lengths. Further, the obtained discrete lengths of glass liquid are directly sprayed on the sizing rod core 10 to form a cylindrical layer on the sizing rod core 10, that is, a glass fiber tube, and the glass fiber tube is composed of randomly oriented glass fibers that are uniformly or non-uniformly wound.

[0028] The glass fiber tube forming device 100 of the present utility model includes a sizing rod core 10 and a spinning mechanism. The spinning mechanism has a spinning nozzle 20, and the spinning nozzle 20 is provided with a nozzle orifice for ejecting molten glass liquid to form a glass liquid stream. The spinning nozzle 20 rotates around the sizing rod core 10 to directly form the ejected glass liquid on the sizing rod core 10 to form a glass fiber tube. In the present utility model, the spinning nozzle 20 rotates around the sizing rod core 10, and the ejected glass liquid is formed on the sizing rod core 10 to form a glass fiber tube, reducing the stretching of the glass fiber during the manufacturing process of the glass fiber tube, thereby reducing the breakage and burr generation of the glass fiber filaments.

[0029] In one embodiment, please refer to Figure 1 , the spinning mechanism has a plurality of spinning nozzles 20.

[0030] It can be understood that the spinning mechanism may include a plurality of glass melting devices or other high-polymer melting devices.

[0032] It can be understood that the distances between multiple nozzle orifices and the sizing rod core 10 gradually increase along the direction from one end to the other end of the spinning nozzle 20, causing the density of the glass fiber tube to change. The smaller the distance between the nozzle orifice and the sizing rod core 10, the greater the density of the formed glass fiber tube; the greater the distance between the nozzle orifice and the sizing rod core 10, the smaller the density of the formed glass fiber tube. Thus, the density in the axial or circumferential direction of the glass fiber tube can be controlled.

[0033] In one embodiment, please refer to Figure 1 , the glass fiber tube forming device 100 further includes a driving member 30, a mounting plate, a driving wheel and a driven wheel.

The spinning nozzle 20 is arranged on the driven wheel, the driving wheel is arranged at the output end of the driving member 30, and the driven wheel is in transmission connection with the driving wheel.

[0034] In one embodiment, please refer to Figure 1 , the driving wheel is a driving gear 40, the driven wheel is a driven gear 50, and the driven gear 50 is in meshing transmission with the driving gear 40.

[0035] It can be understood that the driving member 30 is a motor.

The spinning nozzle 20 is arranged on the driven gear 50, and the driving gear 40 is arranged at the output end of the driving member 30. The rotation of the motor drives the rotation of the driving gear 40, the rotation of the driving gear 40 drives the rotation of the driven gear 50, and further drives the spinning nozzle 20 arranged on the driven gear 50 to rotate, so as to realize the rotation of the spinning nozzle 20 around the sizing rod core 10, and directly form the ejected glass liquid on the sizing rod core 10 to form a glass fiber tube.

[0036] In one embodiment, please refer to Figure 1 , a sliding groove is formed in the radial direction of the driven wheel, and the spinning nozzle 20 is slidably connected with the driven wheel through the sliding groove.

[0037] It can be understood that by providing the sliding groove, the spinning nozzle 20 is slidably connected with the driven wheel to adjust the distance between the spinning nozzle 20 and the sizing rod core 10, thereby adjusting the density in the axial or circumferential direction of the glass fiber tube.

[0038] In one embodiment, please refer to Figure 1 , the diameter of one end of the sizing rod core 10 gradually decreases.

[0039] It can be understood that in order to facilitate the separation of the glass fiber tube from the sizing rod core 10, the diameter of one end of the sizing rod core 10 gradually decreases.

Specifically, the traction mechanism 60 can be two traction rollers disposed on both sides of the glass fiber tube. The two traction rollers traction the glass fiber tube to move away from the textile mechanism to separate the glass fiber tube from the sizing rod core 10.

[0042] It can be understood that by controlling the traction speed of the traction mechanism 60 and the rotation speed of the spinning nozzle around the sizing rod core 10, the shape of the obtained glass fiber tube can be controlled, which can be tubular, spiral sheet, etc.

[0043] In one embodiment, please refer to Figure 1 , the glass fiber tube forming device 100 further includes a glue coating mechanism 70. The glue coating mechanism 70 coats glue on the glass fiber tube.

[0044] It can be understood that by using an adhesive, such as a silicone adhesive, to coat the glass fiber tube, the comprehensive performance of the glass fiber tube, such as flexibility, rigidity, voltage resistance, etc., can be further improved.
