Description

Technical Field

[0001] This utility model relates to the field of intelligent quilting machine technology, specifically to a machine head wire breakage sensing mechanism. Background Technology

[0002] The intelligent quilting machine is a highly advanced sewing device that deeply integrates artificial intelligence technology, including machine learning and computer vision systems. It can automatically detect and recognize extremely complex pattern designs, then perform quilting operations with micron-level precision. The machine also possesses adaptive capabilities, adjusting sewing parameters according to different material properties to ensure stability and consistency in the operation process. In the textile manufacturing industry, intelligent quilting machines are widely used because they not only significantly improve production efficiency and reduce human error and downtime, but also significantly enhance product quality, achieving perfect pattern replication and enhanced durability, thus meeting the demands of the high-end market. Based on practical experience, the existing intelligent quilting machines, while offering significant convenience in automated production, still have several obvious shortcomings that urgently need improvement. One prominent issue is that when a thread breaks during high-speed quilting, the lack of effective real-time monitoring or clear alarm prompts often makes it difficult for operators to detect the breakage in time. This difficult-to-detect thread breakage not only forces quilting operations to stop, affecting production efficiency and continuity, but also results in unstitched or skipped stitch areas on the fabric due to delayed handling, severely impacting the final quilting effect and product quality. Furthermore, this problem also reflects the insufficient automation level of the equipment in anomaly detection and intelligent feedback, failing to fully adapt to the challenges posed by complex working environments or material changes. Therefore, based on actual usage, we have proposed improvements to the aforementioned existing technologies. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The wire breakage detection mechanism at the machine head includes the cable tray; A wire rack is located on the top right side of the wire rack, and an upper wire hook is located on the top left side of the wire rack. A wire breakage sensor mounting plate is located on the top front face of the wire rack, and a wire breakage sensor is mounted on the mounting plate. A machine head is located at the bottom of the wire rack, and a three-hole wire hook is located on the right side of the machine head. A right wire hook and a wire clamp are located on the right side of the machine head, and the right wire hook and the wire clamp are located on the front face of the three-hole wire hook. From top to bottom, a wire take-up lever, a left wire hook, and a wire locking mechanism are arranged on the front right side of the machine head. A needle bar and a needle are located on the front bottom face of the machine head.

[0006] Furthermore, the cable tray is set as an inverted "L-shaped" metal rod, and bolts are installed around the top of the cable tray and between the top of the cable tray and the top of the cable tray.

[0007] Furthermore: the upper hook includes an upper hook body, and a column is provided on the left side of the upper hook body. The bottom of the column is fixedly connected to the top of the cable frame.

[0008] Furthermore: the upper hook body and the wire frame are arranged horizontally parallel to each other, and a cylindrical rod is provided at the center of the top front face of the wire frame.

[0009] Furthermore: a fixing bolt is provided between the wire breakage sensor mounting plate and the wire breakage sensor, and the included angle between the wire breakage sensor mounting plate and the cable tray is set to 90 degrees.

[0010] Furthermore: A connecting rod is provided on the bottom left front face of the machine head, and a circular guide ring is provided at the bottom of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The thread breakage detection mechanism proposed in this paper, after being equipped with a thread breakage sensor, will immediately issue a warning signal if a thread breakage occurs during quilting, ensuring that the operator can respond in a timely manner. Simultaneously, the thread breakage sensor is carefully positioned at a critical location between the upper thread hook and the three-eye thread hook. This centered design effectively improves the overall stability of the sewing thread, preventing the thread from shifting or twisting during high-speed movement. The mounting plate of the thread breakage sensor is firmly fixed to the thread guide frame, ensuring the equipment maintains a stable posture during operation. Furthermore, the thread holes of the upper thread hook, the thread breakage sensor, and the three-eye thread hook are strictly concentrically aligned. This precise geometric fit significantly reduces abnormal thread bounce during machine quilting, thereby improving sewing accuracy and efficiency. When a thread breakage event occurs during quilting, the thread breakage sensor will quickly illuminate a red warning light, visually indicating the location of the fault, facilitating rapid inspection and maintenance.
