Description

Technical Field

[0001] This utility model relates to the field of jacquard machine technology, specifically to a jacquard machine with easily replaceable magnets. Background Technology

[0002] The jacquard loom, as a textile tool, is an important invention of ancient China. Archaeological evidence confirms that silk fabric traces preserved on bronze artifacts from the Yin Ruins in Anyang, Henan Province, include not only plain-weave silk but also jacquard brocade with diamond patterns. This indicates that as early as the Shang Dynasty, my country already possessed looms capable of producing only plain-weave fabrics; only jacquard looms could weave fabrics with complex patterns. Currently, magnets are generally deeply embedded inside the solenoid valve body, which is densely installed between the supports of the vertical needle array. Replacing the magnet requires disassembling the vertical needle supports and linkage springs, a complex operation that easily damages precision components, resulting in lengthy maintenance times and severely impacting production line efficiency.

[0003] For example, patent CN201190209Y discloses a needle selection device for a dual-magnetic electronic jacquard machine, including left and right vertical needles arranged opposite each other. Left and right lifting knives are respectively installed on the outer sides of the left and right vertical needles. A valve body is arranged between the left and right vertical needles, and an electromagnet is installed inside the valve body. A right permanent magnet and a right permanent magnet with opposite magnetic polarities are arranged on the inner side of the right vertical needle, and a left permanent magnet and a right permanent magnet with opposite magnetic polarities are arranged on the inner side of the left vertical needle. A right needle window and a left needle window are respectively opened on the right and left vertical needles above the permanent magnets. A right hook and a left hook of the valve body are respectively arranged on both sides of the valve body to cooperate with the right and left needle windows. Due to the dual-magnetic action, the needle attraction and repulsion are subjected to two different forces, resulting in reliable needle selection, less malfunction, significantly reduced power consumption, and less heat generation. Furthermore, the dual-magnetic action is not affected by residual magnetism, thereby improving the needle selection speed of the electronic jacquard machine.

[0004] However, in most jacquard machines currently in use, magnets are often installed in a fixed manner. When magnets have quality problems, the defects can lead to more tangles and less fabric, severely affecting product quality. Moreover, frequent machine downtime for maintenance makes magnet replacement complex and difficult, requiring a lot of time and effort, and may even require specialized tools and personnel for disassembly, increasing maintenance costs and downtime, and affecting production efficiency. At the same time, the magnet installation area of ​​traditional jacquard machines lacks effective protection, allowing dust and debris to easily enter, affecting magnet performance and the normal operation of the jacquard machine.

Furthermore, the multiple positioning protrusions are evenly distributed circumferentially, further enhancing the accuracy and stability of positioning and better limiting the displacement of the magnet fixed base 301 in multiple directions. This ensures the precision and firmness of the magnet fixed base 301's installation on the jacquard machine body 1, guaranteeing the overall stability of the jacquard machine's performance. Then, the mounting bolts 308 are passed sequentially through the threaded holes of the connecting plate 304 and screwed into the connecting threaded groove 4 of the partition plate 103. This connection has high strength and good stability, firmly connecting the magnet fixed base 301 to the jacquard machine body 1. The mounting bolts 308 also facilitate disassembly and reinstallation, making it convenient for magnet inspection and replacement.

[0034] In summary, the jacquard machine with convenient magnet replacement provided in this embodiment has the following advantages: it significantly improves the maintenance convenience and operational stability of the jacquard machine; the detachable magnet installation structure, combined with the connection and positioning method, makes magnet replacement simple and quick, greatly shortening maintenance time and reducing maintenance difficulty; the protective structure effectively prevents dust and debris from entering, protecting the magnet and related components, extending service life, and reducing the probability of failure; precise positioning and stable connection ensure accurate and secure magnet installation, guaranteeing stable magnetic field performance of the jacquard machine, thereby improving the accuracy and reliability of the jacquard machine's operation, and providing strong support for production continuity and product quality.

[0035] During operation, the magnet block 302 functions in its corresponding position, participating in the jacquard process through magnetic force. The magnet mounting base 301 in the detachable magnet mounting structure securely supports the magnet block 302. The mounting bolts 308 reliably connect the magnet mounting base 301 to the jacquard machine body 1, ensuring the magnet block 302 remains stably in its working position. Then, through the cooperation of the positioning protrusion 402 and the positioning groove 401, the position of the magnet mounting base 301 can be quickly and accurately determined during installation, avoiding misalignment, ensuring installation accuracy, and ensuring a uniform magnetic field distribution within the jacquard machine.
