Description

Prevent net circle off tracking mechanism of device dysmorphism pipe assembly spins in gathering

Technical Field

The utility model relates to a gather and spin preventing net circle off tracking mechanism of device dysmorphism pipe assembly belongs to the technical field that compact spinning machine's negative pressure gathers the device.

Background

In order to eliminate spinning triangle area, a negative pressure pneumatic gathering device for gathering fiber strands is added at the downstream of main drafting, the pneumatic gathering device mainly comprises a special-shaped tube, a grid ring, a small gathering roller, a grid ring and a tension supporting mechanism for supporting the grid ring, the special-shaped tube is provided with a plurality of airflow guide grooves on the tube wall of a gathering working surface, air holes are densely distributed on the upper surface of the grid ring, the grid rings are respectively sleeved on the airflow guide grooves of the special-shaped tube correspondingly, each airflow guide groove corresponds to one fiber strand, and the fiber strands are gathered on the airflow guide grooves while being conveyed along with the rotation of the grid ring under the action of negative pressure airflow in the special-shaped tube, thereby effectively reducing the spinning area and achieving the requirements of reducing yarn hairiness and increasing the strength of the yarn.

During normal spinning, the rotation driving force of the fiber strand conveyed and drawn by the grid ring of the gathering spinning is transmitted by the friction force formed by the gripping of the gathering upper roller of the upper cradle and the gathering small roller in the pneumatic gathering device, so that the grid ring rotates, but the grid ring inevitably shakes left and right in the rotating process, or moves towards one end, and finally runs out of a normal gathering rotating runway, namely the deviation phenomenon occurs. The reasons for this are: 1. the grid ring can form left and right side distortion or different side lengths in the manufacturing and using processes; 2. the gathering upper roller clamping the grid ring is tapered when a big end and a small end appear, and the cradle body pressurizing the gathering upper roller is inclined.

The anti-deviation mechanism is characterized in that corresponding annular grooves are directly formed in a special-shaped pipe or a small gathering roller, the grid ring is installed in the annular grooves, and the grid ring is prevented from deviating, but the depth of the annular grooves is 1-2.5 mm, so that the grid ring is easy to separate from the annular grooves in the rotating process, and the using effect is not ideal. The other structure is that a plurality of limit slide blocks for axially moving and limiting the grid ring are arranged on the tension rod, a stop block with flanges on two sides is also inserted on the limit slide blocks, and the grid ring is transversely limited by the two flanges on the stop block. However, in actual operation, the left-right shaking generated in the rotation process of the grid ring easily causes the looseness of the joint of the stop dog, so that the stop dog cannot effectively control the transverse movement of the grid ring, and the grid ring normally gathers and rotates to deviate from a runway, thereby influencing the spinning performance. Then, be used for all not establishing leading-in face to the flange of grid circle horizontal spacing on the current tension mechanism, when the grid circle was when getting into the dog, can't reduce the grid circle and rotate the in-process and produce and rock the phenomenon about.
