Doubled-thread cutting device

Abstract

The invention discloses a doubled-thread cutting device. The doubled-thread cutting device is used for cutting off a plurality of side-by-side connecting threads in doubled-threads one time, the length of two connecting threads at the outer side is larger than the length of connecting threads in the middle at a notch, a thread end position is concave, and therefore the inconvenience that the thread end position is manually cut out to form a concave shape during terminal connecting is saved. The device comprises a base, a cutting mechanism and a transmitting mechanism, wherein the cutting mechanism is provided with a cutter, and the transmitting mechanism is used for transmitting the doubled-threads. The cutter is provided with a first cutting knife and a second cutting knife which are arranged front to back along the transmitting direction of the doubled-threads, the width of one cutting knife is larger than or equal to the width of the doubled-threads, and the width of the other cutting knife is equal to the sum of the width of other connecting threads except for the two connecting threads at the outer side in the doubled-threads. When the doubled-thread cutting device cuts the doubled-threads, the wider cutting knife can completely cut off the doubled-threads, and the narrower cutting knife can further cut off other connecting threads except for the two connecting threads at the outer side in the doubled-threads. Thus, the doubled-thread cutting device can cut the thread ends of the doubled-threads to be concave one time, the inconvenience that thread ends are manually cut out is saved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a parallel cutting device, in particular to a continuous cutting device capable of cutting the parallel thread into a concave shape at one time. Background technique [0002] Some data lines or transmission lines for data transmission, image or sound signal transmission are commonly used in electronic devices such as liquid crystal displays or computers. Usually this kind of data line or transmission line is not a single metal wire. It is a wire bundle formed by a plurality of thinner connecting wires covered with an insulating layer. Generally, multiple connecting wires are glued side by side. Up to make a flat side-by-side line, referred to as a parallel line. When making parallel lines, a plurality of connecting lines are first arranged and glued by a gluing device to make the connecting lines stick to each other, and then solidified and cooled to obtain a preliminary parallel semi-finished product, and then the obtained pa...

AI Technical Summary

Problems solved by technology

The parallel cutting devices in the prior art are basically one-size-fits-all. After parallel cutting, the thread end is flat, and the staff needs to manually cut the thread end into a concave shape, which is not only troublesome to operate, but also low in production efficiency.
