What is the working principle of the jacquard loom?
Jacquard loom sets the pattern board on the flower tube, turns the pattern board every weft, and presses the flower tube on the horizontal needle. When the grain plate has a hole, the front end of the horizontal needle extends into the grain plate and the hole of the flower tube, and the hook end of the straight needle is still stuck by the lifting knife. When the lifting knife rises, the straight needle rises, and the initial thread hook and pass thread make the heddle rise. At this time, the warp yarn passing through the heddle also rises to form the upper layer of the shed. So, let's take a look at the working principle of jacquard loom.
jacquard loomA mail hammer is hung on it, and when the shed is closed, it plays the role of mail with its weight. When there is no hole on the grain plate, the horizontal needle retreats through the convex head and pushes the corresponding straight needle to lift the hook end of the straight needle away from the blade. The heddle and warp connected to the straight needle do not rise, and the warp sinks to form the lower shed layer. Therefore, the movement of each warp depends on whether the grain plate has holes. The holes of the grain plate are rolled according to the design requirements of the pattern and organization, so the movement of the warp also meets the requirements of the grain plate and organization.
In the development of the modern textile industry, there have been various forms of jacquard looms, such as rapier looms, blade looms, air-jet looms, water-jet looms, multiphase looms, and magnetic weft insertion looms. Compared to the shuttle loom,jacquard loomThe fabric produced has unparalleled advantages in terms of output, quality, variety, etc. It has replaced the shuttle loom in most weaving fields. This pace has been further accelerated, and the textile industry in developed countries has expanded to developing countries.
Due to the technical development of jacquard looms and the needs of the textile industry, air-jet looms have made rapid progress in high-speed, wide-width and serialization. In addition to being widely used in the cotton textile industry, they are increasingly used in yarn-dyed, jacquard and other fabrics.
The jacquard loom process method is derived from the selection of the original waist machine flower, which has been used in oblique looms and horizontal looms in the Han Dynasty.jacquard loomIt appeared in the Eastern Han Dynasty, also called Hua Lou. It is a representative of the higher achievements of China's ancient weaving technology. The jacquard loom was introduced to the West through the Silk Road, which inspired the program control and storage technology in the development of modern electronic computers.
The working principle of jacquard loom
1、jacquard loomMaintenance, you must press the left and right red stop button, indicating that the machine is under maintenance.
2, do not cross the fence. Please slowly pay attention to the stairs up and down, be careful not to slip.
3. Remove the wharf crossbar, and it is strictly forbidden to hang it on the gantry crane ground and fall, injuring equipment and workers.
4. Do not place tools at will during the operation to avoid accidents caused by falling off your hands.
5. When the safety barrier needs to be moved due to maintenance, it must be restored in time after maintenance.
6. After maintenance, when starting up, you should walk slowly for more than 2 weft. You can drive fast only after confirming that the cloth surface quality is normal. After confirming that the equipment is not running normally, you can leave the maintenance machine.
