Description

Technical Field

[0001] This utility model relates to the field of water-based pressure-sensitive adhesive production technology, specifically to a reaction vessel for the production of water-based pressure-sensitive adhesive. Background Technology

[0002] Water-based pressure-sensitive adhesives use water as the dispersion medium and can quickly adhere to object surfaces under slight pressure. They combine environmental friendliness with high performance, making them suitable for sensitive applications such as food packaging and medical devices. The preparation of water-based pressure-sensitive adhesives requires stirring, typically done in a reaction vessel. After the material is discharged from the reaction vessel, it needs to be cleaned to ensure the effectiveness of the next production run. Current cleaning methods mostly involve opening the reaction vessel lid and rinsing the inner wall from above with water pipes. This cleaning process is cumbersome and leaves some hard-to-reach areas, resulting in ineffective cleaning.

[0003] Based on this, this utility model designs a reaction vessel for the production of water-based pressure-sensitive adhesives to solve the above problems. Summary of the Invention

After the stirring is completed, the material is released through the discharge pipe 6. In this embodiment of the utility model, by setting up an installation frame 8, a rotating motor 9, a driving wheel 10, a driven wheel 11, a rotating shaft 12, a stirring rod 13, and a scraper 14, the scraper 14 follows the rotation during the stirring production process to scrape the inner wall of the vessel 1, and simultaneously cleans the inside of the vessel 1, making it convenient to use. In one embodiment of this utility model, two sets of lifting lugs 15 are symmetrically fixed to the top of the lid 2 to facilitate the loading and unloading of the lid 2 and the vessel body 1. The diameter of the driven wheel 11 is larger than the diameter of the driving wheel 10. The scraper 14 is fitted against the inner wall of the vessel body 1. A through groove 16 is opened at the center of the top of the driven wheel 11. A vertical water groove 17 communicating with the through groove 16 is opened in the shaft 12.
