Synthetic leather grain dyeing machine

Abstract

The invention discloses a synthetic leather grain dyeing machine. A cloth feeding roller, a printing upper roller, a printing lower roller and cloth pressing rollers are rotationally arranged on a rack. A scraping and pressing device comprises a scraping and pressing cutter and a plurality of bases, wherein the multiple bases are arranged on the rack and are symmetrically arranged on the two sidesof the cutter back. Each base is provided with a spring, the springs abut against the cutter back of the scraping and pressing cutter, and a blade of the scraping and pressing cutter abuts against acloth outlet roller under the action of the springs. When synthetic leather jumps in the running process, the two faces of the synthetic leather located at the scraping and pressing position are extruded through the cloth outlet roller and the blade correspondingly, stability is still kept, and the scraping and pressing effect is kept stable and cannot suddenly change. The multiple bases are symmetrically arranged on the two sides of the cutter back. Front-back movement of the bases is adjusted through ball screws, then, pressure to the synthetic leather through the scraping and pressing cutter can be adjusted, and the scraping and printing effect of the synthetic leather different in material can be the best. The value displayed by symmetric pressure sensors is the same, the pressure to the different positions of the synthetic leather through the blade of the scraping and pressing cutter is the same, and accordingly it is ensured that the scraping and printing effect is unified.

Description

technical field [0001] The invention relates to the technical field of synthetic leather printing, in particular to a synthetic leather grain dyeing machine. Background technique [0002] After the existing synthetic leather printing machine is printed, manual scraping and pressing printing is required to enhance the printing effect. The disadvantages of manual scraping and pressing are: 1. The work efficiency of manual scraping and pressing printing is low, which increases production costs and labor intensity. The pattern printed on the artificial scraped leather is not uniform due to human factors. 2. The artificial scraping pressure is small, and the produced leather pattern has poor three-dimensional effect and poor simulation; in the existing printing device, the synthetic leather jumps a little during the printing process, which will lead to poor contact between the synthetic leather and the scraping knife.

Problems solved by technology

[0002] The existing synthetic leather printing machine needs manual scraping and pressing printing after printing is completed to enhance the printing effect. The disadvantages of manual scraping and pressing are: 1. The work efficiency of manual scraping and pressing printing is low, which increases production costs and labor intensity. The pattern printed on the artificial scraped leather is not uniform due to human factors

2. The artificial scraping pressure is small, and the produced leather pattern has poor three-dimensional effect and poor simulation degree; in the existing printing device, the synthetic leather jumps a little during the printing process, which will lead to poor contact between the synthetic leather and the scraping knife. At the moment of jumping, the scraping effect changes abruptly, and a non-uniform texture effect suddenly appears in the middle of the synthetic leather with good scraping effect, which affects the appearance. The leather is not parallel, resulting in uneven contact force of the scraping knife on the synthetic leather, and the scraping effect is not uniform
