Description

Technical Field

[0001] The utility model belongs to the technical field of jacquard machine equipment, in particular to a pulley assembly of the jacquard machine. Background Art

[0002] The opening device is an important part of the jacquard machine. The control of the jacquard process is mainly achieved by the opening device. The effect of the jacquard depends on the structure of the opening device. The commonly used jacquard machine has a mature structure. Only one electromagnet is set on each inner plate. Each electromagnet can control the operation of two wire hooks. The two wire hooks control a rope for pulling. The plug hooks set at both ends of the rope are linked and cannot move independently, resulting in limited jacquard effect. With the improvement of the requirements for jacquard effect, the number of wire hooks set on each inner plate can no longer meet the new requirements. In addition, the existing opening device can increase the rope linkage and increase the number of openings by setting a pulley assembly. Due to the increase in the number of openings, the tension on the rope group increases, which makes it easy for uneven acceptance to occur during the sliding process, thereby reducing the service life of the pulley assembly.
