Description

Technical Field

[0001] This utility model belongs to the technical field of warp feeding mechanism equipment for looms, and specifically relates to a warp feeding mechanism for a loom. Background Technology

[0002] Guangduan originated in Guangdong Province, my country. Its weaving technique involves colorful jacquard patterns and is a high-grade silk fabric with heavy warp and weft. The fabric's pattern design, color scheme, and artistic expression have typical Lingnan characteristics.

[0003] Currently, the production of Guangduan (Guangdong satin) is carried out using traditional looms. The earliest loom was a floor-standing loom (called a waist loom). The method of use involved stepping on the warp rollers with one's feet, holding a weft-beating knife in the right hand to tighten the weft threads, and using the left hand to feed the weft. This foot-operated waist loom had no frame; one end of the fabric roll was tied to the waist, and the feet pressed against the other end of the warp roller to tension the fabric. The warp yarns were divided into two layers according to odd and even numbers using a warp divider, and the warp yarns were lifted by a heald rod to form the shed. Weft was fed in using a bobbin and beaten in with a weft-beating knife. The most important achievement of waist loom weaving was the adoption of these three components: the heald rod, the warp divider, and the weft-beating knife. Although this loom appeared simple, it already possessed three-directional movement: opening the shed vertically, feeding the weft horizontally, and tightening the weft back and forth. It is the ancestor of the warp feeding mechanism in modern looms.

[0004] Meanwhile, in the production of Guangduan (a type of satin), it is necessary to ensure the stability of the overall structure, so the door wire structure is added. However, at present, there is little involvement of the door wire transmission structure in looms. Utility Model Content

The gate roller 202 is positioned above the warp roller 201. The gate roller 202 is provided with gate yarns for the fabric, and the warp roller 201 is provided with warp yarns for the fabric.

[0034] The machine frame is also equipped with a weft-beating mechanism 5, which includes a reed frame 501, a weft-beating connecting rope 502, a striking rod 503, a support rod 504, and a support base 505. The support base 505 is installed at the bottom of the machine frame, and the support rod 504 is rotatably engaged with the support base 505. One end of the striking rod 503 is hinged to one end of the support rod 504, and the other end of the striking rod 503 is connected to the reed frame 501. The reed frame 501 is suspended from the machine frame by the weft-beating connecting rope 502, and one end of the warp and weft threads passes through the reed frame 501. The reed frame 501 moves relative to the machine frame through the weft-beating connecting rope 502, the striking rod 503, the support rod 504, and the support base 505, thereby bends and tightens the warp and weft threads to form the weft yarn, and flattens the weft yarn to ensure aesthetics. The added warp ensures the structural stability of the finished product of the satin.

[0035] In this embodiment, the warp roller 201 rotates with the frame, and a first limiting member 203 is provided at the point where the warp roller 201 rotates with the frame;

[0042] Specifically, the support rod 504 is provided with a hinge groove, one end of the impact rod 503 is engaged with the hinge groove, and a hinge pin 5041 is provided on the hinge groove to engage with one end of the impact rod 503.

[0043] In this embodiment, the upright rod 504 is located between the warp feeding mechanism 2 and the reed frame 501, so as to ensure that the reed frame 501 moves relative to the warp feeding mechanism 2.

[0044] In summary, the warp feeding mechanism 2 of the loom in this embodiment is equipped with a warp roller 201 and a gate yarn roller 202. The gate yarn and warp yarn are tightened at the reed frame 501 to form the weft yarn, ensuring the structural stability of the finished product of the subsequent wide satin. At the same time, the reed frame 501 moves relative to the machine frame, making the overall weft yarn flat and beautiful. The above structure can ensure the structural stability and beauty of the finished product of the wide satin.
