[0002] Polyurethane adhesive is an important component of the rapidly developing polyurethane resin. It has excellent performance and has been widely used in many aspects. It is one of the important varieties of the eight major synthetic adhesives. During the processing and production of polyurethane adhesive, emulsification and stirring are required.

[0003] In the prior art, conventional stirring equipment for processing polyurethane glue mostly simply stirs the polyurethane glue through a stirring component. During the stirring process, the polyurethane glue is mixed unevenly, especially making it difficult to mix the polyurethane glue that is far apart from top to bottom, resulting in low stirring and mixing efficiency. At the same time, during the stirring process, the polyurethane glue needs to maintain a corresponding temperature. The traditional water jacket heats unevenly and inefficiently, and there is a temperature difference in the polyurethane glue in the tank, resulting in poor quality of the polyurethane glue.

The scraper 602 is fixedly installed on the side of the stirring rod 601 close to the inner wall of the tank body 1, and the scraper 602 is movably fitted to the inner wall of the tank body 1.

[0022] In this embodiment, the stirring rod 601 rotates with the cylinder 5, so that the stirring rod 601 and the scraper 602 stir the polyurethane glue in the tank body 1, and the scraper 602 can scrape off the polyurethane glue remaining on the inner wall of the tank body 1 during discharge.

[0023] Specifically, the conveying mechanism 9 includes a transmission rod 901, a spiral blade 902 and a rectangular opening 903. The transmission rod 901 is fixedly installed on the lower surface of the output shaft of the second motor 8. The transmission rod 901 is located inside the cylinder 5 and is provided with a spiral blade 902. The left and right side walls of the cylinder 5 are provided with a rectangular opening 903 near the lower side.

[0024] In this embodiment, the rectangular opening 903 allows the polyurethane glue on the outside of the cylinder 5 to flow into the cylinder 5, and the transmission rod 901 rotates with the output shaft of the second motor 8. The transmission rod 901 drives the spiral blade 902 in the cylinder 5, so that the spiral blade 902 drives the polyurethane glue to move upward in the cylinder 5.

[0025] Specifically, the transmission rod 901 is a hollow structure, and mechanical seals 12 are provided at positions corresponding to the upper and lower side walls of the transmission rod 901 and the air distribution box 7 . A through hole 13 is opened at positions corresponding to the transmission rod 901 and the upper side wall of the tank body 1 .

[0026] In this embodiment, the transmission rod 901 facilitates gas flow, the mechanical seal 12 makes the transmission rod 901 better sealed between the upper and lower side walls of the gas box 7, and the through hole 13 facilitates the installation and rotation of the transmission rod 901 on the upper side wall of the tank body 1.

[0027] Specifically, the air distribution mechanism 10 includes an air inlet hole 101 and a one-way air outlet head 102.

[0028] In this embodiment, the air inlet hole 101 allows the hot air in the air box 7 to flow into the transmission rod 901, and then blown out through the one-way air outlet head 102 to heat the polyurethane glue in the cylinder 5.

[0029] Specifically, the heating mechanism 11 includes an extraction component 111, an electric heating box 112, a conduit 113, a controller 114 and a temperature sensor 115.

The controller 114 is installed on the left side of the tank body 1, and the temperature sensor 115 is embedded in the left side wall of the tank body 1 near the lower side.

[0030] In this embodiment, the temperature sensor 115 monitors the temperature of the polyurethane glue in the tank body 1. When the temperature is lower than the set value, the information is fed back to the controller 114. The controller 114 enables the extraction component 111 to draw the gas in the tank body 1 into the electric heating box 112. The electric heating box 112 heats the gas. The heated gas flows into the gas distribution box 7 through the conduit 113.

[0031] When in use, various raw materials of polyurethane glue are poured into the tank body 1 through the feeding valve 2. After the raw materials are injected, the feeding valve 2 is closed, and the cylinder 5 is driven to rotate through the first motor 4. The cylinder 5 drives the stirring rod 601 in the stirring mechanism 6 to rotate, so that the stirring rod 601 and the scraper 602 stir the polyurethane glue in the tank body 1. At the same time, the scraper 602 can scrape off the residual polyurethane glue on the inner wall of the tank body 1 when discharging. During the stirring process, the transmission rod 901 in the conveying mechanism 9 is driven to rotate through the output shaft of the second motor 8. The transmission rod 901 drives the spiral blade 902 to rotate in the cylinder 5, so that the spiral blade 902 drives the polyurethane glue to move upward in the cylinder 5. The cylinder 5 rotates in opposite directions to the spiral blade 902. The polyurethane glue moving upward flows into the tank body 1 through the upper opening of the cylinder 5, and the polyurethane glue in the lower tank body 1 flows into the cylinder 5 through the rectangular opening 903. In the process of stirring, the polyurethane glue can circulate up and down, so that the polyurethane glue can be fully mixed and stirred, and the stirring and mixing efficiency is greatly improved. The temperature of the polyurethane glue in the tank body 1 is monitored by the temperature sensor 115 in the heating mechanism 11. When the temperature is less than the set value, the information is fed back to the controller 114. The controller 114 enables the extraction component 111 to draw the gas in the tank body 1 into the electric heating box 112. The electric heating box 112 heats the gas. The heated gas flows into the air distribution box 7 through the conduit 113. The hot air in the air distribution box 7 flows into the transmission rod 901 through the air inlet 101 in the air distribution mechanism 10, and is then blown out through the one-way air outlet head 102 to heat the polyurethane glue in the cylinder 5. Since the polyurethane glue flows up and down, the polyurethane glue can be heated quickly and evenly to avoid temperature differences, thereby greatly improving the production quality of the polyurethane glue.

[0032] In summary, the stirring equipment for processing polyurethane glue can move the polyurethane glue up and down during the stirring process, so that the polyurethane glue can be fully mixed and stirred, and the stirring and mixing efficiency can be greatly improved. During the stirring process, the polyurethane glue can be quickly and evenly heated to avoid temperature differences, thereby greatly improving the production quality of the polyurethane glue.
