[0027] The production process of traditional fiberglass pipes needs to go through the following processes: yarn beating, weaving, tube passing, and sizing. Each process node may cause the fiberglass filaments of the fiberglass pipe to break and generate burrs. Therefore, the fiberglass on the surface of traditional fiberglass pipes is likely to fall off and is easily inhaled into the lungs or stuck into the skin. In view of this situation, a fiberglass pipe 100 is provided.
[0028] Please refer to Figures 1-3 , the fiberglass pipe 100 provided by the present utility model includes a fiberglass pipe layer 1, and the fiberglass pipe layer 1 is formed by spraying randomly oriented uniformly or non-uniformly wound fiberglass.
[0029] It can be understood that the fiberglass pipe 100 provided by the present utility model is prepared by a fiberglass pipe forming device 200. The fiberglass pipe forming device 200 includes a sizing rod core 10 and a spinning mechanism. The spinning mechanism has a spinning nozzle 20. The spinning nozzle 20 is provided with a nozzle opening for ejecting molten glass liquid to form a glass liquid thin stream. The spinning nozzle 20 rotates around the sizing rod core 10 to directly form the ejected glass liquid thin stream on the sizing rod core 10 and then form the fiberglass pipe layer 1 of the fiberglass pipe 100.
[0030] It can be understood that the spinning mechanism includes devices such as a glass melting device, a metering pump, and a spinneret assembly. The spinneret assembly is the last set of components through which the spinning melt passes. The functions of the spinneret assembly are as follows: First, it filters the molten glass liquid to remove impurities and gel particles that may be entrained in the melt to prevent clogging of the spinning nozzles; second, it enables the melt to be fully mixed to prevent differences in melt viscosity; third, it evenly distributes the melt to the nozzle orifices of each spinning nozzle 20 to form a thin stream of glass liquid. A gas jet is applied at the nozzle orifice of the spinning nozzle 20, thereby stretching and breaking the thin stream of glass liquid into discrete lengths. Further, the obtained discrete lengths of glass liquid are directly sprayed onto the sizing rod core 10 to form a cylindrical layer on the sizing rod core 10, that is, the glass fiber tube layer 1 of the glass fiber tube 100. The glass fiber tube layer 1 is formed by spraying glass fibers randomly oriented and uniformly or non-uniformly wound.
[0031] In one embodiment, please refer to Figure 4 , the spinning mechanism has a plurality of spinning nozzles 20.

[0034] It can be understood that the distances between the plurality of 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 layer 1 of the glass fiber tube 100 to change. The smaller the distance between the nozzle orifice and the sizing rod core 10, the greater the density of the glass fiber tube layer 1 of the formed glass fiber tube 100; the greater the distance between the nozzle orifice and the sizing rod core 10, the smaller the density of the glass fiber tube layer 1 of the formed glass fiber tube 100. In this way, the density of the glass fiber tube layer 1 of the glass fiber tube 100 in the axial or circumferential direction can be controlled.

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 the glass fiber tube layer 1 of the glass fiber tube 100.
[0038] In one embodiment, please refer to Figure 4 , a chute is opened in the radial direction of the driven wheel, and the spinning nozzle 20 is slidably connected to the driven wheel through the chute.
[0039] It can be understood that by setting the chute, the spinning nozzle 20 is slidably connected to the driven wheel to adjust the distance between the spinning nozzle 20 and the sizing rod core 10, so as to adjust the density of the glass fiber tube layer 1 of the glass fiber tube 100 in the axial or circumferential direction.
[0040] In one embodiment, please refer to Figure 4 , the diameter of one end of the sizing rod core 10 gradually decreases.
