[0036] Traditional fiberglass tube production involves the following processes: beating, weaving, threading, and sizing. The stretching and weaving processes can cause glass fiber breakage, resulting in burrs. These burrs can lead to poor quality after gluing the fiberglass tube. Furthermore, limited equipment capacity during weaving and threading limits production efficiency. To address this issue, a fiber tube forming device 100 is provided.

[0037] Please refer to Figure 1 The fiber tube forming device 100 provided by the present invention includes a sizing rod core 10, an axial fiber mechanism 20, a longitudinal fiber mechanism 30, and a glue coating mechanism 40. The axial fiber mechanism 20 includes a guide ring 21. After the axial fibers 22 pass through the guide ring 21, they are evenly distributed on the outer surface of the sizing rod core 10 to form an axial fiber layer. The longitudinal fiber mechanism 30 is arranged adjacent to the axial fiber mechanism 20 and includes a guide hole 31. The longitudinal fibers 32 pass through the guide hole 31 and are spirally wound around the outer surface of the axial fibers 22 of the sizing rod core 10 to form a longitudinal fiber layer. The glue coating mechanism 40 is arranged adjacent to the longitudinal fiber mechanism 30 to coat the axial fiber layer and the longitudinal fiber layer with glue.

[0038] In this embodiment, the sizing rod core 10 provides support and a winding base for the axial fibers 22 and longitudinal fibers 32. The sizing rod core 10 can be in the shape of a cylinder, a rectangular parallelepiped, a cube, or other polyhedral prism, without limitation. The sizing rod core 10 can be made of a thermosetting polymer material, such as phenolic resin, epoxy resin, or polyurethane, or a metal material, such as a pure metal or alloy.

[0039] In this embodiment, the axial fiber mechanism 20 includes a guide ring 21, which provides axial fibers 22 to the sizing rod core 10 through the guide ring 21. After passing through the guide ring 21, the axial fibers 22 are evenly distributed on the outer surface of the sizing rod core 10, forming an axial fiber layer. The longitudinal fiber mechanism 30 is disposed adjacent to the axial fiber mechanism 20 and includes a guide hole 31. The longitudinal fibers 32 pass through the guide hole 31 and are helically wound around the outer surface of the axial fibers 20 of the sizing rod core 10, forming a longitudinal fiber layer.

[0040] It is understood that the axial fibers 22 and the longitudinal fibers 32 can be synthetic fibers, such as polyester, nylon, aramid, etc., or inorganic fibers, such as glass fibers, metal fibers, etc. The axial fibers 22 and the longitudinal fibers 32 can be monofilaments or multifilaments, preferably multifilaments, which are multifilaments composed of a bundle of multiple single fibers. First, the axial fibers 22 are formed on the outer surface of the sizing rod core 10. The axial fibers 22 are evenly distributed along the outer surface of the sizing rod core 10. They can be spirally distributed along the axial direction of the sizing rod core 10, or they can be distributed parallel to the axial direction of the sizing rod core 10 to form an axial fiber layer. Then, the longitudinal fibers 32 are spirally wound around the outer surface of the axial fibers 22 to form a longitudinal fiber layer. Since there is no intersection between the axial fibers 22 and the longitudinal fibers 32, the stretching and weaving of the fibers are reduced, thereby reducing fiber breakage and the generation of burrs.

[0041] In this embodiment, the gluing mechanism 40 is disposed adjacent to the longitudinal fiber mechanism 30 to apply glue to the axial fiber layer and the longitudinal fiber layer to bond the axial fiber layer and the longitudinal fiber layer. The glue-coating solution can be silica sol or other adhesive glue, which is not limited here. Preferably, the glue-coating solution is silica sol, which has good stability and special chemical properties, including high temperature resistance, chemical stability, and high adsorption. The axial fiber layer and the longitudinal fiber layer after gluing undergo a subsequent curing process, such as high-temperature drying, to form a fiber tube.

[0042] As a preferred embodiment, the fiber tube forming equipment of the present invention is particularly suitable for glass fibers, which are prone to breakage and burrs during stretching and weaving. The coating solution is preferably silica sol. The silica glass fiber tube combines the strength of glass fiber with the temperature resistance and chemical resistance of silica gel, and can be widely used in insulation protection in the electronics, electrical, automotive and other industries.

[0043] In one embodiment, the axial fiber mechanism 20 includes an axial yarn drum 23 , which provides axial fibers 22 . The axial fibers 22 are spirally distributed along the axial direction of the sizing rod core 10 .

[0044] In one embodiment, please refer to Figure 1 The axial fiber mechanism 20 includes an axial yarn tube 23 , which provides axial fibers 22 , and the axial fibers 22 are distributed parallel to the axial direction of the sizing rod core 10 .

[0045] As can be understood, a plurality of axial yarn tubes 23 are disposed circumferentially around the sizing core 10. Each axial yarn tube 23 provides a group of axial fibers 22. Each group of axial fibers 22 can be identical or different, and can be monofilament or multifilament. The plurality of groups of axial fibers 22 are evenly distributed along the outer surface of the sizing core 10 to form an axial fiber layer. The parallel distribution of the axial fibers 22 along the axial direction of the sizing core 10 can increase the expandability of the fiber tube. The denser the parallel distribution of the axial fibers 22 along the axial direction of the sizing core 10, the better the expandability.

[0046] In one embodiment, please refer to Figure 1 The longitudinal fiber mechanism 30 includes a mounting plate 33, a driving wheel 35, a driven wheel 36 and a longitudinal yarn tube 37. The mounting plate 33 is provided with a through hole for the axial fiber 22 to pass through, and the axial fiber 22 passes through the through hole and the guide ring 31 in turn and is evenly distributed on the outer surface of the sizing rod core 10. The driving wheel 35 is provided on the mounting plate 33. The driven wheel 36 is transmission-connected to the mounting plate 33 with the driving wheel 35. A center hole 361 is provided in the center of the driven wheel 36 for the sizing rod core 10 to pass through. The sizing rod core 10 is fixedly connected to the mounting plate 33 through the center hole 361. The longitudinal yarn tube 37 provides the longitudinal fiber 32 and is provided on the side of the driven wheel 36 away from the mounting plate 33.

[0047] It can be understood that the mounting plate 33 is provided with through holes for the axial fibers 22 to pass through, and the number of through holes corresponds one to one to the number of groups of axial fibers 22. After each group of axial fibers 22 passes through the corresponding through holes in turn, they are concentrated through the guide ring 31 and then evenly distributed on the outer surface of the sizing rod core 10.

[0048] It can be understood that the driving wheel 35 is provided on the mounting plate 33. The passive wheel 36 is connected to the driving wheel 35 in a transmission manner on the mounting plate 33. The driving wheel 35 is driven by a driving member 34. The driving member 34 can be provided on the mounting plate 33 or not. The driving member 34 can be a DC motor, a stepping motor, a servo motor, etc. The driving wheel 35 is connected to the output end of the driving member 34. In this way, the driving member 34 drives the driving wheel 35 to rotate, and the driving wheel 35 drives the passive wheel 36 to rotate, thereby driving the longitudinal yarn tube 37 located on the passive wheel 36 to rotate around the sizing rod core 10, so that the longitudinal fibers 32 provided by the longitudinal yarn tube 37 are spirally wound around the outer surface of the axial fibers 22 of the sizing rod core 10 to form a longitudinal fiber layer.

[0049] Preferably, the driving wheel 35 is a driving gear, and the driven wheel 36 is a passive gear, and the passive gear and the driving gear are meshed for transmission.

[0050] In one embodiment, please refer to Figure 1 The longitudinal fiber mechanism 30 also includes a support 38, the support 38 is arranged on the passive wheel 36, the longitudinal yarn tube 37 is arranged on the support 38, and the support 38 is provided with a guide ring 21 for the axial fiber 22 to pass through and a guide hole 31 for the longitudinal fiber 32 to pass through in sequence along the direction of the axial fiber 22. The guide ring 21 is arranged perpendicular to the sizing rod core 10.

[0051] As can be understood, placing the guide ring 21 and the guide hole 31 on the support 38 in sequence along the direction of travel of the axial fibers 22 not only saves space but also facilitates the formation of the axial fiber layer and the longitudinal fiber layer. Helically wrapping the longitudinal fibers 32 around the outer surface of the axial fibers 22 can improve the tensile properties of the fiber tube. The denser the helically wrapping of the longitudinal fibers 32 along the axial direction of the sizing rod core 10, the better the tensile properties.

[0052] In one embodiment, please refer to Figure 1 The fiber tube forming apparatus 100 further includes a curing mechanism 50 , which is disposed downstream of the gluing mechanism 40 and is configured to cure the gluing axial fiber layer and the longitudinal fiber layer to form a fiber tube.

[0053] Specifically, the curing mechanism 50 may be a high-temperature drying structure.

[0054] In one embodiment, please refer to Figure 1 The fiber tube forming device 100 further includes a traction mechanism 60 , which is disposed downstream of the curing mechanism 50 . The traction mechanism 60 tractions the fiber tube so that the fiber tube moves relative to the sizing rod core 10 .

[0055] In one embodiment, please refer to Figure 1 The traction mechanism 60 includes two traction rollers provided on both sides of the fiber tube. The two traction rollers pull the fiber tube in a direction away from the fiber shaft mechanism 20 to separate the fiber tube from the sizing rod core 10.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
