Description

Technical Field

[0001] The invention relates to the technical field of braiding machines, in particular to a concentric pay-off type high-speed braiding machine. Background Art

[0002] The traditional high-speed braiding machine is also called the Maypole braiding machine. After the invention of the Maypole braiding machine, the spindles in the braiding machine generally run in a left-handed sinusoidal trajectory and a right-handed sinusoidal trajectory in a cycle. The spindles have inner strings to outer strings or outer strings to inner strings, and the braiding wire is from short to long or from long to end. The braiding wire is woven at a very high frequency.

[0003] During the operation of the traditional Maypole knitting machine, the knitting wire is rubbed back and forth in the spindle tension mechanism, causing uneven tension of the knitting wire and easily causing the phenomenon of splitting and back-threading of the product, which increases the difficulty of spindle design and limits the speed increase of the knitting machine;

[0004] After repeated experiments and verification of the structure, the main technical problems mentioned above are:

[0005] 1: Although the traditional Maypole braiding machine can also be called a concentric pay-off type, the spindles rotate concentrically with the conveying disc during the concentric conveying process. The track space between the spindles is large. The large track of the guide rail reduces the adjustment flexibility of the braiding line during the braiding conversion process, which easily causes uneven tightness and the phenomenon of split or back wire.

[0006] 2: The spindle and the spindle seat cannot guarantee concentric rotation. The spindle is not stable when running along the trajectory, the braiding line fluctuates greatly, and the overall operation cannot guarantee flexible and reliable movement, resulting in a decrease in the speed of the braiding machine.

[0007] Therefore, we propose a concentric pay-off high-speed braiding machine. Summary of the invention

[0008] The object of the present invention is to provide a concentric pay-off type high-speed braiding machine to solve the problems raised in the above background technology.

[0021] The outer wall of the dial is provided with inner grooves in a circular array, and the inner walls of the inner grooves coincide with the outer wall of the positioning shaft.

[0022] The spindle outer chord guide rail and the spindle inner chord guide rail have the same structure, and the outer wall of the spindle cam seat is provided with an outer chord cam matching the spindle outer chord guide rail and an inner chord cam matching the spindle inner chord guide rail.
