Description

Technical Field

[0001] This utility model relates to the field of textile fabric sizing technology, specifically a quantitative fabric sizing device. Background Technology

[0002] Current sizing technology mainly applies sizing agents to fabrics through spray nozzles. However, the distribution of the sprayed liquid is uneven, with some areas having higher or lower sizing agent concentrations, and some parts not being sprayed at all, resulting in inconsistent sizing effects on the fabric.

[0003] Another common sizing method involves immersion combined with pressing. A pressing tank is filled with sizing solution, ensuring the fabric is thoroughly soaked. Subsequently, a rolling mill is used to press the wet fabric to remove excess sizing solution. While this method ensures uniform fabric treatment, its drawback is the excessive amount of sizing solution used, resulting in significant resource waste. Furthermore, the pressing process is difficult to precisely control, making it impossible to accurately adjust the final liquid content of the fabric, thus affecting the quality and effectiveness of subsequent processing.

[0037] Working principle:

[0038] First, the prepared greige fabric is placed in the fabric cart of the feeding mechanism (an A-frame can be used). The greige fabric is placed in the fabric trough by the fabric loosener of the feeding mechanism, and is then conveyed by the fabric loosener to the top of the liquid sizing mechanism. During this process, the tension adjustment mechanism of the feeding mechanism ensures that the fabric is flat. The flat fabric enters the liquid sizing mechanism downwards, where the opposing liquid rollers of the liquid sizing mechanism simultaneously convey the sizing agent to both sides of the greige fabric. The rollers of the liquid sizing mechanism can convey liquid of different weights onto the fabric as needed. After liquid sizing, the greige fabric is collected again on the fabric roll of the A-frame by the take-up mechanism.

[0039] When the pressure cylinder is activated, it moves the entire roller support to the left, causing the liquid-applying rollers of the two sets of sizing components to approach and press against each other. The first pressure adjustment mechanism changes the pressure between the liquid-applying rollers of the two sets of sizing components; clockwise adjustment increases the pressure, and counterclockwise adjustment decreases it. The second pressure adjustment mechanism changes the pressure between the distribution roller and the liquid-applying roller. The first worm gear eccentric adjustment mechanism adjusts the pressure between the supply roller and the transmission roller. When the worm is rotated, the installation position of the supply roller rotates around the center of the worm gear, thus changing the distance between the supply roller and the transmission roller, thereby achieving the required pressure adjustment. Similarly, adjusting the second worm gear eccentric adjustment mechanism adjusts the pressure between the liquid-applying roller and the distribution roller.
