Description

Technical Field

[0001] The utility model relates to the technical field of water-based laminating adhesive production, and more specifically, to a water-based laminating adhesive reactor. Background Art

[0002] Water-based laminating adhesive is an environment-friendly adhesive, mainly used for the surface processing of printed products to improve the surface gloss, strength, and water resistance of printed products. It is an adhesive with water as the solvent or dispersant. Compared with traditional oil-based glues, it has the advantages of high solid content, low viscosity, good process applicability, strong adhesion, and non-toxicity.

[0003] In the patent with the publication number CN 219922902 U, a water-based laminating adhesive reactor is disclosed, which includes a reactor body. Support legs are symmetrically installed on the reactor body. One end of the reactor body is connected to a feed pipeline, and a conical feeding cylinder is installed on the feed pipeline. The bottom of the reactor body is integrally provided with a conical discharge cylinder, and the bottom of the conical discharge cylinder is connected to a discharge pipeline. A control valve is provided at the bottom end of the discharge pipeline. Sampling devices for laminating adhesive extending into it are symmetrically provided at the top of the reactor body. The device of this application has a simple structure, which can not only increase the heating reaction speed of water-based laminating adhesive, but also perform sampling work, without using a sight glass to observe its melting state, preventing the problem of incomplete internal reaction.

[0004] The above device fixedly installs the electric heating plate at the inner bottom end of the reactor, which makes the temperature of the lower part of the raw material higher than that of the upper part and the temperature of the outside higher than that of the inside when the raw material is heated. The raw material is unevenly heated, resulting in uneven reaction process and unstable temperature control, thus affecting the quality of water-based laminating adhesive. The above device also does not have the function of being convenient to clean after production.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0011] As a further solution of the present utility model, positioning pins are rotatably installed on the edge of the reactor body, the positioning pins are engaged with the top cover, and a handle is fixedly connected to the outside of the top cover.

[0012] As a further solution of the present utility model, the spray nozzles penetrate the reactor body, and the spray nozzles are arranged at equal circumferential intervals.

[0013] As a further solution of the present utility model, a water valve is fixedly installed on the outside of the annular pipe, and a thermometer is fixedly installed on the top cover.

After passing through the annular pipe, clear water is injected inward through the spray nozzles to adjust the concentration. Compared with heating by arranging heating pipes on the inner wall of the reactor body, the stirring type central heating can make the raw materials heated more evenly, and can improve the quality of the aqueous film laminating adhesive.

[0017] The utility model has a kettle body, a stirring motor, a scraper, a heater, a worm, a worm gear, etc., and after the water-based coating adhesive is produced and discharged, the hand wheel is turned to drive the worm to rotate the worm gear, thereby turning the kettle body over, and a high-speed water flow is sprayed into the kettle body through a water pump through an annular pipe and a nozzle, and the stirring motor is turned on to make the scraper clean the inner wall of the kettle body. This makes the residual raw materials drip to the discharge pipe under the action of gravity, thereby reducing waste. The high-speed water flow impacts the inner wall of the kettle body as well as the stirring shaft, the fixed rod, etc., and cooperates with the rotation of the scraper, so that the inside of the kettle body can be completely cleaned with high cleaning quality.
