Description

Automatic drawing and slitting top machine device

technical field

The invention relates to the field of tops, in particular to an automatic drawing, rolling and slitting tops machine.

Background technique

The traditional top making machine has a complex structure and covers a large area. It can only produce long tops, and the produced long tops are coiled into a large roll on the take-up device. However, since the length of the commonly used tops is 30cm to 5m, after the existing tops machines produce long tops, the long tops must be subjected to secondary processing so as to cut the long tops to obtain appropriate length tops. This secondary processing is usually done by hand, so it is less efficient and more expensive.

In response to the above problems, some people have developed an automatic top machine that can cut tops while producing tops. Such automatic top machines usually use a reciprocating pulling device to clamp iron wires and short hairs and make them into tops. The equipment to be pulled Pull the tops out to a certain length and then cut the tops by cutting equipment. Among them, the pulling device usually adopts the lead screw nut structure to realize the reciprocating movement.

The advantages of using the screw nut structure for the pulling equipment are: it is suitable for producing tops with a length of about 30cm to 1.5m, and can achieve precise control, so that the produced tops are very smooth and of high quality. Such tops are mainly used for manual DIY and other purposes.

The length of decorative tops is usually more than 2m, and since decorative tops are generally viewed from a distance, the requirements for smoothness are low. When producing decorative long tops, if the lead screw nut structure is used, the length of the required lead screw is too long, and the cost of the long lead screw (more than 3m) is too high, which will cause a sharp increase in production costs. The quality of the tops is relatively low, and the pulling equipment using the screw and nut structure is not worth the loss.
