[0001] This utility model relates to the field of fiberglass pipe production technology, specifically to a fiberglass pipe winding machine. Background Technology

[0002] Fiberglass pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. They are made by winding glass fibers with a resin matrix layer by layer onto a rotating mandrel according to process requirements, with quartz sand evenly spread between the fibers as a sand layer. In the production process of fiberglass pipes, a winding machine is required to wind the material onto the mandrel.

[0003] Chinese Patent No. CN210309113U discloses an unwinding device for a fiberglass pipe winding machine, comprising: an unwinding frame and an unwinding shaft rotatably mounted on the unwinding frame at both ends, the unwinding shaft extending in a front-to-back direction; multiple positioning components and multiple separating sleeves sleeved on the unwinding shaft, each pair of adjacent positioning components being separated by a separating sleeve; a positioning pull rod passing through the multiple positioning components and locking the multiple positioning components and the multiple separating sleeves at each end in the axial direction by a locking nut; and multiple yarn guiding units fixedly arranged in the front-to-back direction on the unwinding frame, each yarn guiding unit including a yarn guiding ring and a yarn guiding buckle, the yarn guiding ring being axially arranged in a left-to-right direction, the multiple yarn guiding rings corresponding to each other facing right and directly opposite the multiple separating sleeves. This unwinding device can be adapted to different specifications of fiberglass yarn rolls by changing the sleeves.

[0004] However, in the above technical solution, the unwinding device can be adapted to different specifications of glass yarn rolls by changing the sleeve. But in use, the guide rod or guide ring needs to be adjusted according to the glass fiber of different diameters to prevent the glass fiber from being too thick or too thin and not matching the guide rod or guide ring.

[0020] Example 1

[0021] like Figures 1-4As shown, this utility model proposes a fiberglass pipe winding machine, including a winding machine body 1, a mounting frame 2, yarn guide rollers 3, and a guiding assembly. The winding machine body 1 is provided with a movable structure, and the mounting frame 2 is connected to the movable part of the movable structure. The movable structure is selected from, but is not limited to, a linear motor. Multiple yarn guide rollers 3 are arranged in parallel and are rotatably connected to the mounting frame 2. Multiple guiding assemblies are provided and connected to the mounting frame 2. The guiding assembly includes yarn guide rods 4, connecting rods 5, and adjusting components 6. Multiple connecting rods 5 are arranged in parallel, and the number of yarn guide rods 4 corresponds to the number of connecting rods 5. The yarn guide rods 4 are connected to one end of the connecting rods 5, and the other end of each connecting rod 5 is connected to the adjusting component 6. The adjusting component 6 is connected to the mounting frame 2. On the mounting frame 2, the adjusting component 6 consists of a fixed plate 7, a movable plate 8, and an adjusting rod 9. The fixed plate 7 is connected to the mounting frame 2. A limiting groove 10 is opened on the side of the fixed plate 7 near the movable plate 8. The movable plate 8 is arranged parallel to the fixed plate 7. A sliding groove is opened on the fixed plate 7 to slide and connect with the movable plate 8. Multiple radially distributed guide grooves 11 are opened on the movable plate 8. Each guide groove 11 is slidably connected to the adjusting rod 9. One end of the adjusting rod 9 is slidably connected to the limiting groove 10. The other end of the adjusting rod 9 is connected to the connecting rod 5. When the guiding component is in use, the movable plate 8 slides along the fixed plate 7, causing the adjusting rod 9 to move linearly along the sliding groove. The change in the spacing between the adjusting components 6 causes the spacing of the yarn guide rod 4 to change through the connecting rod 5.

[0022] Example 2

[0023] like Figures 2-4 As shown, the fiberglass pipe winding machine proposed in this utility model has a more detailed structure than that in Embodiment 1. The guide assembly also includes a support rod 12 and a connecting sleeve. The support rod 12 is connected to the fixing plate 7, and the other end of the support rod 12 is connected to the connecting sleeve. The connecting sleeve is connected to the mounting frame 2.

[0024] In an optional embodiment, the adjusting member 6 further includes a control rod 13 and a locking bolt 14. Two control rods 13 are symmetrically arranged. The control rods 13 pass through the fixed plate 7 and are connected to the moving plate 8. The fixed plate 7 has a sliding groove for the movement of the control rods 13. The number of locking bolts 14 corresponds to the number of control rods 13. The locking bolts 14 are threaded onto the control rods 13.

[0025] In an optional embodiment, the fixed plate 7 has protrusions at both ends, and dovetail grooves 15 are provided on the opposite side of the protrusions. The dovetail grooves 15 are slidably connected to the dovetail blocks 16 on the movable plate 8. The cooperation between the dovetail grooves 15 and the dovetail blocks 16 can assist the movement of the movable plate 8 and prevent it from tilting during movement.

[0026] In an optional embodiment, a protective plate 17 is detachably connected to the protrusion of the fixed plate 7. The protective plate 17 is arranged parallel to the movable plate 8, and the upper end face of the protective plate 17 is provided with a slope. The protective plate 17 can prevent the glue on the glass fiber from dripping and causing blockage. The slope can guide it to fall and prevent it from accumulating.

[0027] In an optional embodiment, the mounting bracket 2 is L-shaped and has multiple crossbars 18 connected to it. The crossbars 18 are detachably connected to the connecting sleeve by bolts.

[0028] In an optional embodiment, one end of the connecting rod 5 is connected to a support frame 19, and a yarn guide rod 4 is connected to the support frame 19. Limiting rods 20 are slidably connected within the multiple support frames 19, and the limiting rods 20 are fixedly connected to the support frame 19 in the middle position. The limiting rods 20 can be removed to reduce the adhesion and influence of any adhesive that may be present.

[0029] In summary, when this utility model is used, the wrapped glass fiber passes through the guide roller 3 and enters the gap between the guide rods 4. The glue on the surface of the glass fiber drips onto the protective plate 17 and is guided by it to drip into the storage box on the main body 1 of the winding machine. The linear motor on the main body 1 of the winding machine can drive the mounting frame 2 to move back and forth to wind the glass fiber. If it is necessary to change to glass fiber of different thicknesses, the locking bolt 14 is loosened by the operator to pull the control rod 13 to drive the moving plate 8 and the dovetail block 16 to slide along the dovetail groove 15. At the same time as the position of the adjusting rod 9 in the radial guide groove 11 changes, one end of it in the limiting groove 10 also changes, and multiple adjusting rods 9 move synchronously to the middle position. The spacing between the adjusting rod 9, the connecting rod 5, and the guide rod 4 can be adjusted to accommodate glass fibers of different sizes. The connecting rod 5 can be prevented from shaking by sliding on the limiting rod 20 on the support frame 19. If it is necessary to consider the glue adhering to the limiting rod 20, it can be removed to reduce the impact.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
