A fiberglass winding device

Abstract

This application provides a fiberglass winding device, which includes a frame, a mounting base, a rotating sleeve, multiple ceramic wheel modules, and a mandrel. A metal component has multiple clearance holes arranged along the annular direction of the metal component. A metal induction switch is mounted on the support base and is used to sense the metal component rotating with the ceramic wheel to determine the rotational state of the ceramic wheel. Fiberglass fed by the multiple ceramic wheel modules is wound around the surface of the mandrel along the annular direction. When the metal component rotates, the metal induction switch continuously senses the metal component and outputs a sensing signal. When the metal induction switch is positioned relative to the clearance holes, it cannot sense the metal, causing the sensing signal to be interrupted, thus determining the interruption state of the fiberglass. This achieves autonomous identification of broken wires, avoiding reliance on human visual identification, reducing labor costs, and ensuring the effectiveness of the fiberglass winding device in identifying broken wires.

Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass winding devices, and in particular to a fiberglass winding device. Background Technology

[0002] With the development of technology, fiberglass winding devices are applied in industry. These devices are used to immerse fiberglass in resin and wind it onto the mandrel by controlling the relative movement between the nozzle and the mandrel. In existing technology, fiberglass winding devices include a frame, a rotating sleeve, a ceramic wheel, and a mandrel. The rotating sleeve is rotatably connected to the frame, the ceramic wheel is connected to the rotating sleeve and allows the fiberglass to be threaded through, and the mandrel is mounted on the frame. The fiberglass output from the ceramic wheel is wound around the mandrel in a circular direction. However, these devices rely entirely on the operator's visual inspection to identify broken fibers, making it impossible for existing fiberglass winding devices to detect broken fibers.

[0051] Mounting base 20 is disposed on the inner side of frame 10 and mounted on frame 10 so as to fix mounting base 20 on the inner side of frame 10.

[0052] The rotating sleeve 30 is disposed on the outside of the mounting base 20. The rotating sleeve 30 is rotatably connected to the mounting base 20 and rotates along the axis of the rotating sleeve 30 to facilitate adjustment of the position of the rotating sleeve 30 relative to the mounting base 20. The rotating sleeve 30 is provided with a central through hole 30a.

[0053] Multiple ceramic wheel modules 40 are mounted on the same rotating sleeve 30 and arranged sequentially along the circumference of the rotating sleeve 30, so that the multiple ceramic wheel modules 40 rotate with the rotating sleeve 30, thereby facilitating the adjustment of the positions of the multiple ceramic wheel modules 40. Each ceramic wheel module 40 includes a support base 41, a ceramic wheel 42, a metal part 43, and a metal induction switch 44. The support base 41 is connected to the rotating sleeve 30. The ceramic wheel 42 is rotatably connected to the support base 41 to facilitate the adjustment of the position of the ceramic wheel 42 relative to the support base 41. The ceramic wheel 42 is used for fiberglass insertion. The metal part 43 is mounted on the ceramic wheel 42 and rotates with the ceramic wheel 42. The metal part 43 is provided with multiple clearance holes 43a, which are arranged along the annular direction of the metal part 43. The metal induction switch 44 is mounted on the support base 41 and is used to sense the metal part 43 rotating with the ceramic wheel 42 to determine the rotation state of the ceramic wheel 42.

[0054] The core mold 50 is installed on the frame 10. The core mold 50 has a central through hole 30a. Fiberglass fed by multiple ceramic wheel modules 40 is wound around the surface of the core mold 50 in a circular direction. At this time, when the metal part 43 rotates, the metal induction switch 44 continuously senses the metal part 43 and outputs a sensing signal. When the metal induction switch 44 is arranged relative to the clearance hole 43a, the metal induction switch 44 cannot sense the metal, so that the sensing signal is in an interrupted state, so as to determine the interruption state of the fiberglass and realize the autonomous identification of broken wires. This avoids relying on human eyes to identify broken wires, prevents the product weight problem that may be caused by the failure to detect broken wires in time, helps to reduce labor costs, and ensures the identification effect of broken wires by the fiberglass winding device.

[0055] Please refer to the attached document. Figures 1-4 In this embodiment, a metal induction switch 44 is disposed on one side of a metal component 43, with the sensing end of the metal induction switch 44 facing the metal component 43. This allows the metal induction switch 44 to sense the metal component 43. The metal component 43 is fixedly connected to a ceramic wheel 42 and is located on the side of the ceramic wheel 42 facing the metal induction switch 44, so that the metal component 43 rotates with the rotation of the ceramic wheel 42, thereby facilitating the adjustment of the position of the metal component 43. The metal component 43 is sheet-shaped, and the clearance hole 43a is circular or elongated. The diameter of the clearance hole 43a is larger than the diameter of the sensing end of the metal induction switch 44, avoiding deviation of the sensing end of the metal induction switch 44. When the sensing end of the metal induction switch 44 is arranged relative to the clearance hole 43a, the sensing signal is interrupted to determine the interruption state of the fiberglass, thereby achieving autonomous identification of broken wires. This avoids relying on human eyes to identify broken wires, prevents the frequent failure to detect product weight problems that may occur due to broken wires, helps reduce labor costs, and ensures the identification effect of broken wires by the fiberglass winding device. When the fiberglass thread breaks, the system sends a command to stop operation and provides an audible and visual alarm to prompt the operator to handle the situation promptly, ensuring product quality and avoiding waste of raw materials and labor.

[0056] In this embodiment, the support base 41 is provided with a rotating shaft 411; the ceramic wheel 42 is rotatably sleeved on the rotating shaft 411 and rotates relative to the rotating shaft 411, so that the ceramic wheel 42 can rotate relative to the support base 41 through the rotating shaft 411, ensuring the rotation effect of the ceramic wheel 42; the outer surface of the ceramic wheel 42 is provided with an annular wire groove 42a, which is used for glass fiber to pass through; so that the glass fiber can pass through the space of the annular wire groove 42a to pass through the ceramic wheel 42; the rotating shaft 411 is provided with a limiting part, which is located outside the ceramic wheel 42, to restrict the ceramic wheel 42 from disengaging from the rotating shaft 411, ensuring the position of the ceramic wheel 42 relative to the rotating shaft 411.

[0058] In this embodiment, the ceramic wheel 42 has a locking groove 42b on the side wall facing the metal part 43; the metal part 43 has a locking arm 431, which is sleeved in the locking groove 42b and engaged with the locking groove 42b, so that the metal part 43 can be engaged with the ceramic wheel 42 through the engagement groove 42b and the locking arm 431, so that the metal part 43 is fixedly connected to the ceramic wheel 42, ensuring that the metal part 43 is stationary relative to the ceramic wheel 42.

The glass fibers pass through the through holes 45a and enter the annular guide groove 42a of the ceramic wheel 42, causing the ceramic wheel 42 to rotate. During this process, continuous glass fibers sequentially pass through the through holes 45a and around the guide groove. In normal production, the tension from the forward-pushing glass fibers drives the ceramic guide wheel to rotate continuously. The ceramic guide wheel and the metal sensing plate are coaxially connected, so the metal sensing plate rotates synchronously with the ceramic guide wheel. Optionally, the multiple guide hooks 45 and the ceramic wheel 42 are detachably connected to the support base 41 for easy daily cleaning and replacement.

The fiberglass output from the ceramic wheel modules 40 enters the impregnation element 60 and is impregnated in the impregnation element 60. The fiberglass output from the impregnation element 60 is then wound sequentially onto the surface of the mandrel 50, so that the impregnated fiberglass is wound onto the surface of the mandrel 50, thereby increasing the strength and hardness of the fiberglass, improving its corrosion resistance, water tightness and waterproofness, and improving its electrical insulation performance.

[0063] In this embodiment of the application, the fiberglass winding device further includes a current collector ring 70, which is located on the side of the rotating sleeve 30 facing away from the impregnated part 60.
