Description

Automatic drawing, rolling and slitting wool top machine device

Technical Field

The invention relates to the field of wool top machines, in particular to automatic drawing, rolling and slitting wool top machine equipment.

Background

The traditional wool top machine has a complex structure, occupies a large area, can only produce long wool tops, and the produced long wool tops are coiled into a large coil on a coiling device. However, since the length of the wool tops generally used is 30cm to 5m, the conventional wool top machine must perform secondary processing on the long wool tops after producing the long wool tops to cut the long wool tops into wool tops of appropriate length. This secondary processing is typically done manually by a human, and is therefore inefficient and costly.

In view of the above problems, an automatic top machine capable of cutting tops while producing top edges has been developed, in which a reciprocating pulling device is usually used to clamp iron wires and short hairs and form them into tops, and the tops are cut by a cutting device after the pulling device pulls the tops out by a certain length. Wherein, the pulling device usually adopts a screw nut structure to realize the reciprocating movement.

The advantage that pulling equipment adopted the screw nut structure lies in: the method is suitable for producing wool tops with the length of about 30 cm-1.5 m, and can realize accurate control, so that the produced wool tops are very smooth and have high quality. Such tops are mainly used for manual DIY and the like.

The length of the decorative wool top is usually more than 2m, and the requirement on smoothness is low because the decorative wool top is generally viewed at a distance. When the long wool tops for decoration are produced, if a screw nut structure is adopted, the length of the required screw is too long, the cost of the long screw (more than 3 m) is too high, the production cost is increased sharply, and in addition, the pulling equipment adopting the screw nut structure is unreliably lost due to the lower quality required by the long wool tops for decoration.
