Fabric deburring device

Abstract

The invention relates to a fabric rough selvedge cut-off device. The fabric rough selvedge cut-off device comprises a rack, fabric selvedge detecting mechanisms and selvedge detecting and cut-off transmission mechanisms, wherein the fabric selvedge detecting mechanisms and the selvedge detecting and cut-off transmission mechanisms are arranged at the two ends of the rack. Each selvedge detecting and cut-off transmission mechanism comprises a movable carriage. Each fabric selvedge detecting mechanism comprises a position detector which is installed on the movable carriage of the corresponding selvedge detecting and cut-off transmission mechanism. The fabric rough selvedge cut-off device further comprises a laser cut-off mechanism and rough selvedge finishing mechanisms. The laser cut-off mechanism comprises laser tubes, laser cutting heads and laser reflectors. Both the laser tubes and the laser reflectors are fixed to the rack, and the laser cutting heads are arranged on the movable carriages of the selvedge detecting and cut-off transmission mechanisms at the two ends of the rack correspondingly. Laser beams emitted by the laser tubes are projected onto the laser cutting heads through the laser reflectors. The rough selvedge finishing mechanisms are arranged at the two ends of the rack correspondingly. The fabric rough selvedge cut-off device is applicable to various fabric varieties, high in production efficiency, safe, reliable and convenient to operate.

Description

technical field [0001] The invention relates to a fabric burr cutting device, in particular to a fabric burr cutting device for inkjet printing, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] In the production of textile dyeing, finishing and printing, during the weaving process of the fabric, side hairs of different lengths will be formed on both sides of the fabric, forming fabric burrs. If the fabric burrs are not pre-treated before the digital printing of the fabric, it will be damaged The printing nozzle causes damage. Since the printing nozzle is the core component of the digital printing machine and has a high value, it must be protected. Therefore, it is required to have no burrs on both sides of the fabric before inkjet printing. In this way, the burrs need to be cut off to ensure that the fabric burrs Will not clog the printing nozzles of inkjet printing machines. [0003] At present, the removal of fabric burrs...

Problems solved by technology

But above-mentioned two kinds of excision methods all have deficiencies: electric heating cutter can't be suitable for all kinds of fabrics, as for such as pure cotton, acrylic fiber etc. its ignition point is not high, and the afterburning property is good, and the contact surface of burr and air Large, it is easy to cause fire; but for fabrics with heavy weight and high ignition point, the speed of the equipment cannot be increased when cutting burrs with an electric cutter, which makes the cutting efficiency low; some chemical fibers will melt and shrink when cut with an electric cutter In this way, there may be a notch at the cutting line, and it is very easy to cause the fabric to tear from the notch of the selvage during the subsequent fabric expansion process; and if the fabric burr is cut off manually with a knife, It makes the edge trimming not straight, and the labor intensity is high and the efficiency is low. At the same time, the manual trimming process is not safe, which increases safety hazards.

Therefore, the existing edge hair removal method greatly affects the normal operation of the inkjet printing process and affects the entire production efficiency.

[0004] At the same time, in the prior art, especially when the shuttleless machine forms the fabric, since the package yarn fixed by the weft yarn reel is unidirectional weft insertion, the two ends of each weft yarn are free ends, and the formed selvedge is also a burr. During the weaving process, the raw edges tend to be upturned or lie down on the cloth surface, that is, the state of the raw edges is irregular. When the raw edges are upturned, the weft yarn (false yarn side yarn) cannot be cut well, which will directly affect the subsequent inkjet printing effect
