Cloth spreading device of digital printing machine

Abstract

The invention provides a cloth spreading device of a digital printing machine. The two sides of a guide belt of the digital printing machine are each provided with a sliding rail. A sliding mechanism is mounted on each sliding rail. The two ends of a cloth pressing roll and the two ends of a two-way spreading roll are mounted on the sliding mechanisms located on the two sides of the guide belt respectively. Therefore, in the operating process, when a textile arrives at a feed port, the two-way spreading roll makes the textile completely spread out in the transverse direction so as to guarantee that the textile can smoothly arrive at the cloth pressing roll; through control over thrust of air cylinders and under the action of self weight of the cloth pressing roll, the textile is pressed by the cloth pressing roll onto the upper surface of the guide belt and effectively pasted to the surface of the guide belt, and a servo power mechanism controls movement of the cloth pressing roll on the sliding mechanisms so as to make the cloth pressing roll and the guide belt move relatively and synchronously. As a result, the textile on the cloth pressing roll is smoothly pasted to the guide belt in a wrinkleless mode, and subsequent printing quality and accuracy are guaranteed.

Description

technical field [0001] The present invention mainly relates to the technical field of printing, and more specifically relates to a cloth spreading device of a digital printing machine. Background technique [0002] At present, digital inkjet printing has been widely used in the digital textile printing manufacturing industry. Since the digital inkjet printing is a non-contact printing, in order to ensure the accuracy and quality of the subsequent inkjet printing, it is necessary to avoid scratching the wrinkled part. Inkjet nozzles, which require textiles to spread evenly and not wrinkle. [0003] Specifically, the digital printing machine usually sticks the textile on the sticky printing transmission belt, which can not only fully flatten the textile, but also make the textile move synchronously with the printing transmission belt. It can be seen that, How to ensure that the textiles are fully flattened and wrinkle-free on the sticky printing belt is the key to inkjet prin...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention proposes a digital printing machine cloth spreading device, which solves the problem that when the speed of the guide belt is fast in the existing cloth spreading device, the pressure roller will swing back and forth under the action of the guide belt, and its own high speed The situation of rotation, so that the pressure of the textile is uneven, it is easy to wrinkle the textile and scratch the nozzle, and affect the subsequent printing accuracy; moreover, the excessive pressure will cause indentation of the textile, which will affect the technical problem of the quality of the textile
