Tension-free continuous cloth feeding device for single pass digital inkjet printing machine

Abstract

The invention discloses a tension-free continuous cloth feeding device of a single pass digital ink-jet printing machine. The tension-free continuous cloth feeding device comprises a grey cloth frame and grey cloth put on the grey cloth frame and is characterized in that the grey cloth sequentially passes space between a pair of first cloth pressing rollers, a cloth loosening roller, a conveying belt and space between a pair of second cloth pressing rollers to be conveyed to the printing machine, wherein one of the pair of first cloth pressing rollers is connected to a first cloth feeding motor; the cloth loosening roller is arranged below the first cloth pressing rollers; the conveying belt is horizontally put, is arranged below the cloth loosening roller and is connected to a cloth feeding main wheel and a cloth feeding counter wheel, and the cloth feeding main wheel is connected to the conveying motor; one of the pair of second cloth pressing rollers is connected to a second cloth feeding motor; the pair of second cloth pressing rollers are arranged above the conveying belt; the grey cloth coming out of the conveying belt reaches the space between the pair of second cloth pressing roller sequentially through a tension adjusting device and an angular cloth guiding device and then reaches the printing machine through a cloth rectifying device. The tension-free continuous cloth feeding device has the beneficial effects of simple structure, good centering effect and improvement of printing quality.

Description

technical field [0001] The invention relates to a tension-free continuous cloth feeding device for a single-pass digital inkjet printing machine. Background technique [0002] A single pass inkjet printing machine is a digital printing machine in which dozens or hundreds of nozzles are fixed on the top of the printing belt and keep a certain spraying distance from the printing belt, that is, the nozzles do not move and the printing belt is moving at high speed. The production of pass inkjet digital printing machine is usually at 35m / min~75m / min. The single pass inkjet digital printing machine currently on the market, because there is no belt-driven first-level loose stacking device, resulting in single pass When the inkjet digital printing machine is in high-speed production, it is difficult for the cloth feeding system to maintain a fast and loose tension-free supply of cloth, resulting in untimely cloth supply, poor cloth centering effect, and high tension after printing, ...
