Flat filament brush-making head

Abstract

The invention relates to a flat filament brush-making head which is characterized in that a filament cutting fixed tool apron and a filament cutting movable tool apron are arranged behind a brush nozzle, wherein a filament cutting fixed tool is fixed in the filament cutting fixed tool apron, a flat filament guiding groove is formed in the filament cutting fixed tool and vertically crossed with a center hole of the brush nozzle, the tool rod of a filament cutting movable tool can slide up and down in the guiding groove of the filament cutting movable tool apron, the tool point of the filament cutting movable tool is attached onto the end surface of the filament cutting fixed tool, a raised ring is arranged at the upper end head of the tool rod of the filament cutting movable tool, and a spring is nested on the tool rod of the filament cutting movable tool and supported between the raised ring and the filament cutting movable tool apron; side plates which are parallel to each other are connected to the upper part of a fixing seat, a movable tool driving cam and a swinging rod are mounted between two side plates, a cam shaft is arranged at the center of the movable tool driving cam, two ends of the cam shaft are hinged on the corresponding side plates respectively, the middle part of the swing rod is hinged on the side plates through a pin shaft, the rear end head of the swinging rod is pressed on the movable tool driving cam, and the front end head of the swinging rod is pressed on the upper end surface of the raised ring of the filament cutting movable tool. The brush-making head has a simple structure and low failure rate, and is reliable in motion.

Description

technical field [0001] The invention relates to a brush hair-planting device, in particular to a flat wire hair-planting head. Background technique [0002] When planting brush hair, first drill holes on the bottom plate of the brush body, and then implant the bristles into the holes through the hair planting nozzle. Since the bristles are easy to loosen and fall off, the hair roots of the planted hairs need to be hooped with iron wires and implanted into the holes. Iron wires are generally Use flat or round wire. [0003] The Chinese utility model patent with the publication number 201595369U discloses a wool planting machine, which includes a flat wire hair planting head and a shredding mechanism. The guide rod can move back and forth in the nozzle guide groove of the fixed seat. Each movement of the nozzle completes a hair transplant. Corresponding to each bundle of bristles, there must be a flat wire cut to a certain length. There are punching needles and cutting needle...
