[0002] In the production process of wire packing resin, the precision and efficiency of the feeding link play a decisive role in the quality of the final product. The traditional feeding methods mainly include manual feeding and negative pressure feeding. Manual feeding relies on manpower, which is not only inefficient, but also difficult to ensure the high consistency of the feeding amount each time due to human factors. The wire packing resin formula has very strict requirements on the proportion of various raw materials. Small feeding errors can cause product performance fluctuations, affecting the stability and uniformity of product quality. At the same time, some raw materials used in the production of wire packing resin have irritating odor, corrosiveness or even toxicity. Long-term manual operation can expose workers to dangerous environments and harm their health.

[0003] Although negative pressure feeding reduces labor intensity to some extent, the material and air in the feeding device are not completely separated, and when the gas containing material debris or other dust is discharged outside the equipment, it will pollute the environment and harm the health of workers. In addition, the wire packing resin formula contains multiple raw materials, which need to be premixed before using the feeding device to increase the operation time and production cost. Moreover, the material is easily deposited on the inner wall of the pipeline during transportation. With the passage of time, the residual material gradually accumulates, not only causing material waste and increasing production cost, but also requiring frequent shutdown for pipeline cleaning, which reduces production efficiency.

[0004] To solve the above problems, a negative pressure feeding device for reaction kettle is proposed in the present application. UTILITY MODEL CONTENTS
