Description

Technical Field

[0001] This utility model relates to the field of silk reeling technology, specifically to a structure for detecting rough knots in a reeling machine. Background Technology

[0002] Silk is a natural protein fiber made from silkworm cocoons. It possesses excellent properties such as a soft luster, a supple feel, and excellent moisture absorption and breathability, making it an important raw material for high-end silk products. Winding is a crucial step in silk processing, its purpose being to rewind the reeled raw silk from the frame into bobbins for subsequent weaving or knitting. However, during winding, uneven distribution of sericin, fiber friction, or mechanical action can easily cause rough knots (such as fuzz, silk scraps, and lumps) to form on the silk surface. These knots not only affect the appearance and uniformity of the silk but also lead to problems such as breakage and weaving defects during subsequent weaving, reducing production efficiency and finished product quality.

[0003] Currently, the detection of knots in the silk reeling process mainly relies on optical detection technology. When a knot is detected, the system immediately stops for manual handling. However, due to mechanical inertia, the silk thread continues to travel a distance after stopping, causing a discrepancy between the actual location of the knot and the detected location. Workers need to locate the knot on the silk thread based on the stop signal, but because silk fibers are delicate and knots are tiny, manual positioning is often time-consuming and labor-intensive, and prone to omissions or misjudgments, affecting production efficiency and product quality. Existing solutions mostly focus on improving detection accuracy, but lack effective means for precise positioning after machine stoppage. Therefore, there is an urgent need for a technology that can quickly and accurately locate knots after detection to improve the production efficiency of the reeling process. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a rough knot detection structure for a winding machine, which can quickly and accurately locate the rough knot after detection.

[0005] This utility model discloses a rough knot detection structure for a winding machine, including a winding machine frame and a wire conveyed from top to bottom on the front side of the winding machine frame. A mounting base is provided on the winding machine frame behind the wire. Two baffles are horizontally arranged on the lower side of the mounting base, one on the left and one on the right. One of the baffles has a mounting groove on its upper side, and an upward-illuminating lamp is installed in the mounting groove. A gap is left between the two baffles, and the wire is located in the gap between the two baffles. A thin film is laid on the upper side of the baffle. The film is opaque and covers the lamp, and a central hole is provided in the center of the film. The central hole should be larger than the diameter of the wire and smaller than the diameter of the rough knot. The wire passes through the central hole in the film. A photosensitive sensor is provided on the mounting base above the lamp, facing the lamp. A buzzer is provided on the mounting base. The photosensitive sensor and the buzzer are electrically connected to the controller of the winding machine.

[0006] The principle behind this structure is to detect knots on the wire by combining optical sensing and mechanical obstruction: when the wire passes normally through the central hole of the film, the opaque film blocks the light from the lamp assembly; once a knot appears on the wire, the knot will pull the film down, at which point the light from the lamp assembly is captured by the photosensitive sensor above, triggering the controller to stop and activate the buzzer alarm. Workers can quickly locate the faulty machine through the audible and visual cues, and visually locate the knot by using the film pulled down by the knot, achieving efficient detection and handling.

[0007] To facilitate the downward movement of the membrane by the roughened knot, the side of the baffle closest to the wire is designed with an arc shape. When the roughened knot passes through, the arc shape reduces resistance, making it easier for the membrane to be carried down by the roughened knot, thus ensuring sensitive and reliable detection.

[0008] To increase the strength at the center hole of the film, an annular thickened area is set around the center hole of the film to enhance its tear resistance.

[0009] The present invention provides a knot detection structure for a winding machine. Its advantages include: through the mechanical obstruction of a baffle and a thin film, combined with the optical sensing of a lamp assembly and a photosensitive sensor, it can accurately detect knots on the yarn and immediately stop the machine and sound an alarm in case of a fault; the rounded edge design of the baffle reduces friction, making the thin film easier to move by the knots and improving detection sensitivity; and the annular thickened structure of the thin film's central hole enhances tear resistance, ensuring long-term stable operation. The overall solution is simple in structure and responds quickly, allowing workers to quickly locate the fault location using audible and visual cues, significantly improving detection efficiency and maintenance convenience.

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1 , 2As shown, this utility model discloses a rough knot detection structure for a winding machine, including a winding machine frame and a wire 1 conveyed from top to bottom on the front side of the winding machine frame. A mounting base 3 is provided on the winding machine frame behind the wire 1. Two baffles 5 are horizontally arranged on the lower side of the mounting base 3, one on the left and one on the right. One of the baffles 5 has a mounting groove on its upper side, and an upward-facing lamp group 9 is installed in the mounting groove. A gap is left between the two baffles 5, and the wire 1 is located in the gap between the two baffles 5. The side of the baffle 5 closest to the wire 1 is... The structure is arranged in an arc shape 6. A thin film 4 is laid on the upper side of the baffle 5. The thin film 4 is opaque and covers the lamp group 9. The center of the thin film 4 is provided with a central hole. The central hole should be larger than the diameter of the wire and smaller than the diameter of the rough knot. A ring thickened area 7 is provided around the central hole of the thin film 4. The wire 1 passes through the central hole on the thin film 4. A photosensitive sensor 2 is provided on the mounting base 3 above the lamp group 9, facing the lamp group 9. A buzzer 8 is provided on the mounting base 3. The photosensitive sensor 2 and the buzzer 8 are electrically connected to the controller of the winding machine.

[0015] The principle of the above structure is to detect knots on the wire 1 by combining optical sensing and mechanical obstruction: when the wire 1 passes normally through the central hole of the film 4, the opaque film 4 will block the light from the lamp group 9; once a knot appears on the wire 1, the knot will cause the film 4 to move down together. At this time, the light from the lamp group 9 is captured by the photosensitive sensor 2 above, triggering the controller to stop and start the buzzer 8 to sound an alarm. Workers can quickly locate the faulty machine through the sound and light prompts, and visually find the location of the knot by using the film 4 that has been pulled down by the knot, thus achieving efficient detection and handling.
