Description

A lifting device for ring plate assembly of spinning frame

technical field

The utility model relates to a lifting device for a ring plate assembly of a spinning frame, which belongs to the technical field of textile machinery.

Background technique

Spinning frames are widely used in the textile industry to draw, twist and spin rovings into spun yarns. The spinning frame consists of a feeding mechanism, a drafting mechanism, a twisting and winding mechanism, and a winding and forming mechanism. The twisting and winding mechanism is provided with a yarn guide hook, a ring plate, a traveler, a spindle, a yarn spacer, a spindle belt reel, a tension plate, a balloon ring and a bobbin. The spindle is driven by the spindle to rotate, and the bobbin is set on the spindle. When the spindle rotates, the yarn sliver drives the traveler to rotate around the steel ring. When the arc is in contact, each time the traveler turns, a twist is added to the drafted whisker. The ring is arranged in the ring plate, the ring plate is arranged in the cross arm of the ring plate, and the cross arm of the ring plate makes a regular vertical lifting movement under the control of the winding forming mechanism, so that the spun yarn is wound according to the forming requirements. on the bobbin. In the prior art, the lifting and lowering of the ring plate and the yarn guide plate is realized by a cam mechanism connected to the main shaft of the spinning frame. The mechanism has many parts, complex structure, high energy consumption, and limited control accuracy, and the phenomenon of impact and pause during operation. It will cause yarn forming and yarn quality; in addition, the mechanical cam can only meet the lower winding speed, generally 600m/min-1200m/min, it is difficult to keep up with the needs of modern production.

Utility model content

The technical problem to be solved by the utility model is to provide a lifting device for the ring plate assembly of the spinning frame in view of the above-mentioned prior art, which can effectively avoid the phenomenon of impact and pause, greatly improve the yarn forming and yarn quality, and improve the production efficiency .

The technical scheme adopted by the utility model to solve the above problems is as follows: a lifting device for a ring plate assembly of a spinning frame, which comprises a frame, the top of the frame is provided with a translation support, and one side of the frame is provided with a drive mechanism, The drive mechanism includes a brake servo motor and a three-stage planetary gear transmission box. The output end of the three-stage planetary gear transmission box is provided with a winding sprocket, and a winding chain is arranged between the winding sprocket and the translation support. , a plurality of lifting beams are sequentially arranged below the translation support from left to right, and the front and rear sides of the multiple lifting beams are provided with ring plate assemblies, and the translation support and the multiple lifting beams are connected by traction slings.

A transition sprocket set is arranged above the driving mechanism, one end of the winding chain is connected with the winding sprocket, and the other end bypasses the transition sprocket set and is connected with the translation support.

A rotating shaft is arranged above each lifting beam, and a transition pulley is arranged on the rotating shaft. One end of the traction sling is connected to the translation support, and the other end is connected to the lifting beam after bypassing the transition pulley.

Each rotating shaft is provided with two front and rear transition pulleys.

Compared with the prior art, the advantages of the present utility model are:

1. The utility model can effectively avoid the phenomenon of impact and pause, greatly improve the yarn forming and yarn quality, and the winding speed can reach 1200-2000 m/min, which greatly improves the production efficiency;

2. The drive mechanism of the utility model adopts a servo brake motor, which can also avoid the ring plate from falling off due to gravity when the power is cut off;

3. The utility model has the advantages of simple structure, small volume, no need for subsequent oil maintenance, and high transmission efficiency and control precision.
