Description

Technical Field

[0001] This utility model relates to the field of polyester aqueous dispersion preparation technology, and in particular to a standby feeding mechanism for modified polyester aqueous dispersion. Background Technology

[0002] Modified polyester aqueous dispersions are important polymer materials widely used in coatings, adhesives, textile finishing agents, and leather finishing agents. Compared with traditional solvent-based polyesters, aqueous dispersions have advantages such as environmental friendliness, low VOCs (volatile organic compounds), and ease of processing, meeting the requirements of current green chemistry and sustainable development. However, the preparation process of modified polyester aqueous dispersions involves the precise proportioning of multiple raw materials, control of dispersion stability, and optimization of process conditions. Among these, the accuracy and stability of the feeding process directly affect the performance of the final product. Therefore, we designed a backup feeding mechanism for modified polyester aqueous dispersions. Utility Model Content

[0010] Compared with related technologies, the modified polyester water dispersion system feed mechanism provided by this utility model has the following advantages:

[0011] 1. This utility model provides a standby feeding mechanism for modified polyester water dispersion. By directly opening the feeding control valve on the feeding pipe, the material inside the material pre-storage cylinder is transferred to the inside of the feeding machine. The driving motor drives the feeding conveyor roller to rotate and transfer the material. The material enters the mixing drum through the feeding chute, realizing automatic feeding.

[0012] 2. This utility model provides a backup feeding mechanism for modified polyester water dispersion system. A clockwise stirring motor controls a clockwise stirring shaft to rotate clockwise, using a first stirring plate to drive a first stirring rod for clockwise stirring. Simultaneously, a counter-clockwise stirring motor controls a counter-clockwise stirring shaft to rotate counter-clockwise, using a second stirring plate to drive a second stirring rod for counter-clockwise stirring. This bidirectional stirring operation ensures uniform mixing of materials, improves the stirring efficiency of the device, and thus increases the overall production efficiency of the device. The arrangement of the first and second stirring rods prevents materials from adhering to the surface of the stirring device, improving the cleanliness of the device and avoiding material waste.
