Hydraulic press machine in textile spinning:
Introduction:
Such machines are usually tied by steam pressure or hydraulic press. The main function of this machine is to arrange the yarn, cloth, or other material in layers by applying very high pressure, compress the layers and cut them into shapes, and fasten the bale with an iron fence or strong rope. https://bdfabric.com/bundling-and-baling-process-in-textile-spinning/
Different types of pressure are applied to different types of products. The weight and size of the bale are fixed in advance. Pressure application is also specified depending on the structure and the distance of transport of the material. These presses are made to be extremely strong and high-pressure resistant. The hydraulic press consists of the following parts. https://bdfabric.com/advantages-of-yarn-conditioning/
1. Metal pot
2. Heavy metal vessel or table
4. Vertical pump
5. Ram
6. Metal bar
7. Handwheel etc.
Description and procedure:
The main figure is a vessel made of movable metal. It starts to rise slowly from the bottom with the help of hydraulic pressure. This pressure is applied periodically using eight Vertical Pumps. This pressure pushes a ram under the metal vessel, causing the moving vessel to rise from the bottom to the top.
The heavy metal vessel of the hydraulic press is much like the previous vessel, but not movable or dynamic. This massive metal vessel is supported by four steel pillars. Therefore, the moving vessel is bound to the bottom of the stationary vessel as it moves upwards with the layered material due to the strong pressure. And because of this pressure, the products gradually shrink. In this way, when the bale becomes a certain shape, the bale is well twisted by inserting the fence through the holes in both the pots. Later it is tied with a string or grip. The first moving vessel is brought to a certain height.
Hydraulic press machine in textile spinning:
A rope or metal fence is placed on the lower pot or table. Then the packing cloth or sack is left and the packing material is placed on it according to the weight. Now the goods are held in place by metal bars. The pump is turned on after the top and bottom of the goods are covered with a packing cloth. According to calculations, a certain amount of pressure is applied per square inch. After the baling material is compressed to a certain size, the pump is shut off, the valves are closed, and the metal bars are removed.
Now the bale is well shaped by pulling the packing cloth well and the packing cloth is pulled and sewn around. Hydraulic press pumps usually work in pairs. The size of one pair of pumps is different from the other. Larger pair of pumps make it possible to lift the moving vessel very quickly but the pressure does not fall too much. With the introduction of the hydraulic press, the first large pair frees the next pair. In this way, the next pair is released till the smallest and last pair. As a result, the moving vessel tends to slow down. But the pressure continues to grow stronger and stronger. After the packing is finished, the bale is released by releasing the pressure with the help of a hand wheel and is ready to make the next bale again.
