Description

Technical Field

[0001] The utility model belongs to the technical field of carpet processing, and particularly relates to a wire pulling mechanism for carpet processing. Background Art

[0002] Persian carpets are a traditional Iranian craft with a long history and worldwide renown. Due to their unique craftsmanship and appearance, and their figure-of-eight knotting, Persian carpets are typically woven by hand or semi-mechanized methods due to their specialized structure. This results in complex weaving processes, high difficulty and labor intensity, and low production efficiency. Therefore, improvements in the equipment, mechanisms, or methods required for any single step in Persian carpet weaving are crucial to the overall process.

[0003] As we all know, the weaving process of Persian carpets can basically be summarized into several major steps, such as warp adjustment, weft weaving, and flocking. In traditional technology, different yarns need to be manually sorted out and manually threaded before the flocking process to provide yarns for the 8-shaped buckle weaving. During the processing of the carpet, the required equal-length yarn segments need to be manually spread on a cart, and then the cart is manually pushed to the side of the weaving machine, and the laid yarn is fed into the machine beam of the weaving machine, so that the weaving machine can weave the yarn. When manually spreading the yarn on the cart, it is often necessary to manually pull the yarn on the pay-off mechanism and spread the pulled yarn on the cart mechanism in turn. Manually sorting out different yarns in this way not only affects the yarn pulling efficiency, reduces the carpet processing efficiency, but also increases the physical labor of the workers. Therefore, it is necessary to provide a yarn pulling mechanism for carpet processing to solve the above-mentioned technical problems. Utility Model Content

[0024] The wire pulling mechanism 4 includes a movable frame 401, which is horizontally slidably connected to the frame 1, and a wire clamping frame 402 is fixedly connected to the rear side of the movable frame 401. In some embodiments, a plurality of wire clamping frames 402 are provided, and the plurality of wire clamping frames 402 are distributed at intervals along the axial direction of the movable frame 401. The wire clamping frames 402 are arranged in a one-to-one correspondence with the wire pay-off mechanisms, and can pull the wool yarns on a plurality of wire pay-off mechanisms at the same time. The front side of the wire clamping frame 402 is vertically slidably connected to the wire grabbing frame 403, and two wire grabbing clamps 404 are symmetrically slidably connected to the wire grabbing frame 403. The two wire grabbing clamps 404 cooperate to form a clamping structure for the wool yarn.

[0025] In some embodiments, the movable frame 401, the wire clamping frame 402, the wire grabbing frame 403 and the wire grabbing clamp 404 can replace manual labor in pulling the wool yarn on the wire-releasing mechanism, and can pull the wool yarn to the specified position as needed, so that the required wool yarn can be spread flat on the cart mechanism 3, which not only improves the wool yarn pulling efficiency and the carpet processing efficiency, but also reduces the physical labor of workers.
