What is the working principle of the jacquard loom?


Jacquard loom is a textile tool and one of the important inventions in ancient China. Archaeological evidence shows that traces of silk fabric left on the bronze ware of the Yinhe tomb in Anyang, Henan, indicate that there are not only straight-organized silk, but also jacquard rhombuses. This shows that there have been looms in our country. Ordinary looms can only weave plain fabrics, and fabrics with complex patterns can only use jacquard looms.

The process method of jacquard loom originally originated from waist machine picking, and this process method has been used in oblique loom and horizontal loom in the Han Dynasty. Generally, 1 kill gold (springboard) is used to adjust a comprehensive (warp lifting device) to weave patterns. In order to weave patterns and increase the number of synthetic frames, two comprehensive frames only weave plain weave, 3-4 comprehensive frames can weave twill weave, and more than 5 comprehensive frames can weave satin weave. Therefore, in order to weave complex flowers with large flower-like cycles, the warp must be divided into more groups and gradually form a multi-variety bouquet.

Jacquard loom appeared in the Eastern Han Dynasty, also known as the painting floor. It is a representative of the higher achievements of China's ancient weaving technology. It stores the jacquard program with a pre-emptive drawing book, and then uses the line to pull the ramp entrance. The drawing book is a program that stores pattern information on the magnetizing machine. The hair room that indicates the election and the ear room that indicates hypocrisy are arranged according to the pattern requirements. Usejacquard loomWhen the foot charity thread is connected to the fiber thread of the lifting warp, pulling the foot charity thread on the side of the ear charity thread can play the role of lifting the relevant warp. When weaving, the upper and lower two people cooperate, one to retain the chemical industry, sitting on the three-foot-high flower floor to grasp the flower synthesis, one to step on the foot to attract guards. The scene of weavers and jacquard workers operating jacquard looms together is described in "Xijing Miscellany" by Wang Yi of the Eastern Han Dynasty.

What is the working principle of the jacquard loom?

Injacquard loomOn, the pattern board is set on the flower tube, weaving one at a time over the pattern board, and the flower tube is pressed horizontally once. When the plate has a hole, the head end of the horizontal needle touches the hole of the door plate and the firebox, and the hook end of the straight needle is still stuck on the retract. As soon as the knife came up, the straight thorn came up, lifting the silk through the first row of hooks and through the thread. At this time, the slope penetrating the comprehensive eye also rose, forming the upper layer of anti-pursuit. Hang a hammer on the comprehensive ring under the silk, and rely on its weight to play a comprehensive role when visiting and closing. When the plate has no hole, the horizontal needle retreats through the convex head and pushes the corresponding straight needle. The hook end of the straight needle retracts. The wire and slope connected with the straight needle do not rise, and the slope sinks downward to form an anti-pursuit lower layer. Therefore, the movement of each inclined plane is determined according to whether there is a hole or no space on the board. The hole on the board is rolled according to the design requirements of the pattern and organization, so the movement of the inclined plane also meets the requirements of the pattern and organization.
