Description

Technical Field

[0001] The invention relates to the technical field of textile fabric sizing, in particular to a quantitative sizing device for fabrics. Background Art

[0002] The current sizing technology mainly applies sizing agent to the fabric through a nozzle, but the distribution of the sprayed liquid in this way is uneven, which is manifested as high or low concentration of sizing agent in some areas, or even some parts are not sprayed at all, resulting in inconsistent sizing effect of the fabric.

[0003] Another common sizing method is to use dipping and extrusion, which is done by filling a pressing tank with sizing liquid to ensure that the fabric can be thoroughly soaked in the tank. Subsequently, the wet fabric is squeezed by a padder to remove excess sizing liquid. Although this method can ensure that the fabric is treated evenly, its disadvantage is that the amount of sizing liquid used is too large, resulting in significant waste of resources. At the same time, since the extrusion process is difficult to control accurately, it makes it impossible to accurately adjust the final liquid content of the fabric, thus affecting the quality and effect of subsequent processing.

[0020] Working principle: First, place the prepared grey cloth in the cloth cart of the feeding mechanism (an A-frame can be used). The grey cloth is placed in the cloth groove through the cloth loosening device of the feeding mechanism in a relaxed state, and then transferred to the top of the liquid feeding and sizing mechanism by the cloth loosening device. During this process, the tension adjustment mechanism of the feeding mechanism ensures that the fabric is flat. The flat fabric goes down to the liquid feeding and sizing mechanism, and the opposing liquid rollers of the liquid feeding and sizing mechanism transport the slurry to both sides of the grey cloth at the same time. The rollers of the liquid feeding and sizing mechanism can transport liquids of different weights to the fabric as required. The grey cloth after liquid feeding is collected again on the cloth roll of the A-frame through the collecting mechanism; When the combined pressure cylinder is activated, the entire roller bracket can be moved to the left, so that the liquid rollers of the left and right sizing assemblies are close to each other and squeezed against each other; the first pressure regulating mechanism can change the pressure between the liquid rollers of the two sizing assemblies, and clockwise adjustment will increase the pressure, and counterclockwise adjustment will increase the pressure; the second pressure regulating mechanism can change the pressure between the liquid leveling roller and the liquid leveling roller; the first worm gear eccentric regulating mechanism can adjust the pressure between the liquid supply roller and the liquid transfer roller. When the worm is rotated, the installation position of the liquid supply roller will rotate around the center of the worm gear, so the distance between the liquid supply roller and the liquid transfer roller will change, thereby meeting the pressure regulation requirement. The second worm gear eccentric regulating mechanism can be adjusted in the same way, and the pressure between the liquid leveling roller and the liquid leveling roller can be adjusted through the second worm gear eccentric regulating mechanism.
