Automatic knotting assembly for plastic shaping filaments

Abstract

The invention provides an automatic knotting assembly for plastic shaping filaments. The automatic knotting assembly comprises a knotting base obliquely provided with a working table, and a thread end clamping part and a thread end knotting part are arranged on the working table; the thread end knotting part comprises a thread hooking unit and a thread locking unit; the thread hooking unit comprises a thread hooking needle, a first thread hooking driving mechanism and a second thread hooking driving mechanism, and a thread hooking hook is arranged at the end of the thread hooking needle; and the thread locking unit comprises a thread locking block, a thread locking needle, a first thread locking driving mechanism, a second thread locking driving mechanism and a third thread locking driving mechanism, wherein the thread locking needle is connected to the interior of the thread locking block in a sliding mode, the first thread locking driving mechanism is used for driving the thread locking block to move in the axial direction, the second thread locking driving mechanism is used for driving the thread locking block to swing in the axial direction of the thread hooking needle, the third thread locking driving mechanism is used for driving the thread locking block to move on the working table in the direction perpendicular to the thread hooking needle, and a thread locking hook is arranged at the end of the thread locking needle. The automatic knotting mechanism is used for knotting the plastic shaping filaments to replace manual knotting, and has the advantages of high automation degree and high knotting efficiency.

Description

technical field [0001] The invention relates to a tool for processing plastic sizing wire, in particular to an automatic knotting assembly for plastic sizing wire. Background technique [0002] At present, the brush for daily use mainly includes a brush body and a number of bristles arranged on the brush body, wherein a number of bristles are generally implanted into the brush body through a tufting machine. The bristles can be animal bristles or plastic styling wires. Because the obtaining of plastic setting wire is more convenient, and the cost of plastic setting wire is relatively lower than the cost of animal mane, so existing bristle generally adopts plastic setting wire. [0003] In the process of processing plastic sizing wire, the long strip of plastic sizing wire that has been cooled and shaped will be wound on a square winding frame, so that multiple bending points are formed on the plastic sizing wire, so when using plastic sizing wire When producing the above-m...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of knotting the end of the plastic setting wire, it needs to be done manually by the staff, the degree of automation is low, and the knotting efficiency is low
