Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warp knitting machines, and particularly relates to an automatic warp inserting and removing device. BACKGROUND

[0002] At present, in the warp knitting machine industry, the process of installing and removing the disc head is mainly achieved by manually inserting or pulling out the warp beam into or from the preset disc head group, which is slow in efficiency, has many safety hazards, is high in labor intensity of workers, has poor installation effect, and the cooperation between the warp beam and the disc head is completely aligned by the naked eye, so that the warp inserting and removing action is rough and dangerous, and the warp beam and the disc head are easily damaged. Since the warp beam is heavy, work accidents often occur when the workers manually insert or pull out the warp beam, which easily causes great damage to the body of the operator. On the other hand, the conventional way is to directly use a crane to place the warp beam on the lifting mechanism, which easily damages the lifting mechanism.

[0003] The prior art discloses a warp inserting machine with the application number CN201420388606.2, which comprises a rack base, a lifting device for up-down lifting of the warp beam is arranged at the front end of the rack base, and a moving device for forward-backward movement of the warp beam is arranged at the rear end of the rack base. However, the device of the prior art firstly adjusts the forward-backward movement of the warp beam through a chain wheel, which has poor stability, high shaking frequency, and greatly reduces the warp inserting precision. Secondly, the lifting adjustment only controls one end of the warp beam, and in the lifting process, the roller tightly rotates against the outer surface of the warp beam under the weight of the warp beam to lift it, which greatly wears the warp beam, easily causes many scratches, has low precision, and is time-consuming and laborious. Then, the device needs to be partially placed into the ground or the disc head is pushed upward by using a crane, which is inconvenient to use and operate. Moreover, the warp beam is directly placed on the lifting mechanism, which easily damages the lifting mechanism due to inertia during the installation of the warp beam.

[0004] Based on the above background, an automatic warp inserting and removing device has practical significance and broad prospects. SUMMARY

The unthreading work is opposite to the threading work.
