How much do you know about the loosening method of the opener?

    There are certain methods and techniques for loosening the opener. Now it is mainly divided into two methods, one is in the free state and the other is in the holding state. Let's talk about the difference between these two methods.

　　 (1) The loosening effect of the fiber block in the free state of the opener

　　 1. The method in which the raw material is hit by the machine parts in the free state, so that the raw material is opened by the impulse, is called free impact.

　　 2. The striking parts include angle nails, blades and serrations. For example, the interaction between the roller and the roller in the multi-roller open hunger, and the interaction between the axial opener and the open cylinder in the three-cylinder open hunger, all belong to the opening action of free blowing.

3. Free opening is only a preliminary loosening of the raw materials. The fiber block after opening is still relatively large, and it needs to be opened with strong force, such as dry opening in the holding state, to loosen the large fiber block into small The fiber block or fiber bundle to meet the requirements of carding work.

　　 (2) The loosening effect of the fiber block in the holding state of the opener

　　 When the raw materials are fed into the machine in a holding state, under the impact of opening the hungry part, it is called holding and opening. In cotton spinning, the role between the beater and the cotton feeding roller in the porcupine opener and the cotton cleaning machine, the role between the opening and the cotton feeding roller in wool spinning, and the role of opening in the silk spinning.

　　 Generally speaking, the loosening is achieved by splitting and tearing the raw materials through high-speed striking parts, such as blades, wings, and corner nails, thereby destroying the connection force between the fibers and achieving the purpose of loosening. The above two methods are determined by the different feeding methods of the opener.
