Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to an auxiliary upper head-changing winding mechanism for a wire drawing machine. Background Art

[0002] In the current fiberglass kiln drawing process, there are two drawing methods, one is the cylindrical direct yarn drawing method, and the other is the saddle-shaped cake yarn drawing method. Each machine head must be equipped with an upper wire ring, which pushes the yarn out of the front upper wire ring through the push rod to change the head. After the head or the barrel is changed, the push rod is retracted. Under the action of the push rod and the rotation of the machine head, the yarn exists in a spiral shape between the two winding barrels to form a "yarn ball connection line". This integrated upper wire ring must be cut and cleaned manually after each head change. Not only is the upper waste yarn unusable, but it also produces a lot of hairy yarn that affects the environment. The inner and outer layers of the yarn balls and the upper wire rings must also be cut before unloading the barrel.

[0003] At present, in order to meet the needs of the robot to take the yarn and unload the bobbin, it is necessary to manually cut the yarn connection line between the upper yarn on the upper wire ring and the winding bobbin, so that the robot can participate in the automatic yarn taking and unloading. Such human-machine cross-operation has safety hazards. Due to the poor environment of the glass fiber drawing process and the high labor intensity and low efficiency caused by frequent manual operations, it is not conducive to the complete realization of workshop automation and hinders the automation process of intelligent manufacturing.

[0004] Considering that if the automatic yarn cutting mechanism is used without manual operation, for the cake yarn drawing process, the cake is in the shape of a saddle, and under the action of the push rod, the head and tail yarns pass through the gap between the two winding tubes in a forward and reverse spiral manner without obstacles, and automatic yarn cutting is easier. For the direct yarn drawing process, the cake is cylindrical, the yarn roll diameter is large, and the head diameter is small. The distance between the two yarn rolls forms a deep groove. When the push rod pushes the yarn out, the outer tail yarn is easy to fall into the deep groove and stay for many turns, making it difficult to implement automatic yarn cutting.
