Description

Technical Field

[0001] The invention belongs to the technical field of roller blind fabric equipment, and in particular relates to a production process of a highly flame-retardant and fully light-shielding composite roller blind fabric. Background Art

[0002] Generally, when sizing fabrics, the textiles are directly immersed in a slurry pool or the slurry is directly sprayed on the surface of the textiles. This will easily cause the slurry to flow out of the surface of the fabrics when spraying the slurry, resulting in slurry waste, and will also make the sizing uneven on the surface of the fabrics. In the sizing process, the fabrics are prone to wrinkles, resulting in poor sizing effects. The slurry thickness on the surface of the textiles is different, which can easily lead to inconsistent local hand feel and hardness of the textiles after sizing, reducing the quality of the textiles and the utilization rate of the slurry. At the same time, in order to achieve a shading effect, the coating on the fabric is two or more layers. Since the wear-resistant color glue layer is arranged outward and has a reflective effect, the thicker coating is easy to reflect the sunlight under the reflection of the sunlight. In order to avoid the reflection of the sunlight, scratches and holes are usually regularly made on the surface of the coating by a fine brush to reduce the reflection of light. However, due to the different thicknesses of the coatings, it is difficult to manually create the effect of scratches and holes, resulting in the difficulty in unifying the quality levels during the manufacturing process.

The driving mechanism 20 is arranged on the left and right sides of the intermediate roller 21. The driving mechanism 20 includes a lifting plate 22 and two groups of guide rails 23. The two groups of guide rails 23 are arranged on the front and rear sides of the lifting plate 22 and slide with each other. Two active pulleys 24 are symmetrically arranged on the inner side of the lifting plate 22, and are both rotatably connected to the lifting plate 22. An eccentric wheel 25 is arranged on the top of the lifting plate 22 between the two active pulleys 24, and the eccentric wheel 25 is rotatably connected to the lifting plate 22.

The multiple guide turns of the guide rollers 10 can increase the time the cloth stays in the box 8 and improve the sizing time. At the same time, the multiple windings of the guide rollers 10 can avoid the phenomenon of wrinkles on the cloth during the sizing process and avoid uneven sizing. During this period, the water pump 13 absorbs the slurry in the box 8 through two inlets 17 and filters it through the filter 19 to filter the impurities remaining in the slurry; the slurry is dried by the drying mechanism 2, and the scraping black layer, the silver coating layer, the covering layer and the wear-resistant color glue layer are coated on the surface of the fabric by the black scraping mechanism 3, the silver coating mechanism 4, the covering layer mechanism 5 and the wear-resistant color glue layer mechanism 6 respectively; When the cloth passes through the needle roller assembly 7, a plug-in brush group 30 with different bristle heights is selected according to the coating thickness on the cloth surface, and the corresponding plug-in brush group 30 is driven to rotate to the lower end by the needle roller motor 26, and the driving lifting shaft 31 is used to rotate the eccentric wheel 25, so as to drive the two sets of driving mechanisms 20 to move up and down synchronously as a whole, and holes are inserted on the coating surface by the bristles to reduce the reflection of sunlight. Since the eccentric distance of the eccentric wheel 25 is fixed, deeper holes need to be inserted, and different plug-in brush groups 30 need to be selected. When scratches need to be made to reduce the reflection of sunlight, the middle roller 21 is driven to rotate by the needle roller motor 26, and the scratches are directly brushed on the coating surface by the rotating brush group 29.
