However, existing emulsification devices usually rely on stirring equipment. Stirring equipment often cannot effectively control the particle size in the solution during emulsification, resulting in inconsistent particle sizes and affecting the quality of the final adhesive. Therefore, we have specially designed a polyurethane adhesive homogenizing mixing device. Utility Model Content

A first feed inlet 111 is disposed on the upper side wall of the first main body 11. A first discharge outlet 112 is disposed at the bottom of the first main body 11. The spiral frame 13 is disposed inside the first main body 11 and forms a spiral channel inside the first main body 11.

[0040] Homogenizing device 2 includes a second main body 21, a second cover 22 and an emulsifier 23. The second cover 22 is disposed on the upper end of the second main body 21. A second feed inlet 221 is disposed on the end face of the second cover 22. A second discharge outlet 211 is disposed on the bottom end face of the second main body 21. Multiple emulsifiers 23 are stacked inside the second main body 21.

[0042] As can be seen from this embodiment, a polyurethane adhesive homogenizing equipment includes a premixing device 1 and a homogenizing device 2.

[0043] The premixing device 1 includes a first main body 11, a first cover 12, and a spiral frame 13. The first main body 11 is cylindrical with open openings at both ends. The first cover 12 is connected to the upper opening of the first main body 11. A first feed inlet 111 is formed on one side wall of the upper opening of the first main body 11. The lower opening of the first main body 11 is constricted to form a first discharge outlet 112. The spiral frame 13 is connected to the first main body 11 from the upper opening and is fixed after the first cover 12 is connected to the first main body 11. The spiral frame 13 forms a spiral channel inside the first main body 11. Furthermore, an assembly hole 121 is provided on the end face of the first cover 12, and the spiral frame 13 is connected to the assembly hole 121.

[0044] The homogenizing device 2 includes a second body 21, a second cover 22, and an emulsifier 23. The two ends of the second body 21 are open. The second cover 22 is connected to the upper opening of the second body 21 and has a second feed port 221 formed on it. The second feed port 221 is connected to the first discharge port 112. The lower opening of the second body 21 is closed and is set as the second discharge port 211. Multiple emulsifiers 23 are stacked inside the second body 21.

[0045] The polyurethane adhesive material in the first body 11 is mixed together to form a mixed liquid as it passes through the spiral frame 13. It then enters the emulsification device through the first discharge port 112 for emulsification and is discharged through the second discharge port 211 after emulsification.

[0046] The premixing device 1 is set up to perform preliminary emulsification of polyurethane adhesive raw materials. After the preliminary emulsification of polyurethane adhesive is completed, it is transported to the homogenizing device, where multiple emulsifiers 23 perform homogenization and emulsification of polyurethane adhesive, thereby making the particle size of the polyurethane adhesive solution in the finished product more similar, thus improving product quality.

[0055] The spiral plate 132 is connected to the outer wall of the fixed rod 131. The spiral plate 132 is tangentially arranged to the inner wall of the first body 11 and forms a spiral channel on the outside of the fixed rod 131. The spiral channel plays the role of turbulence and guiding the flow of polyurethane adhesive raw materials.

[0056] Polyurethane adhesive raw material is spirally passed through the first body 11 through the spiral channel. The raw material is mixed together during the spiral passage. Furthermore, the fixing rod 131 is hollow inside and has an open end. It extends through the assembly hole 121 to the outside to form a filler end. A filling hole 1311 is opened on the side wall of the fixing rod 131 connected to the spiral frame 13.

[0057] During use, the polyurethane adhesive raw material can be mixed with the polyurethane adhesive raw material by adding emulsifier into the filling end 1312 during the process of passing through the spiral channel. The added emulsifier enters the spiral channel through the filling hole 1311 and mixes with the polyurethane adhesive raw material.

[0072] By stacking multiple emulsifiers 23, the mixed liquid enters the second body 21 from the first outlet 112 and then sequentially enters the first emulsification chamber 3 and the second emulsification chamber 4 from top to bottom and from inside to outside. It is then output through the first emulsification hole 2321 and the second emulsification hole 2311 to another emulsifier 23 stacked below, thereby gradually breaking it down into finer particles to form a homogeneous emulsion liquid. Finally, it is discharged from the second outlet 211, achieving the purpose of homogeneous emulsification.

[0074] This embodiment provides a polyurethane adhesive homogenizing mixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] The flow deflector 5 is disposed on the mating surface between the first discharge port 112 and the second inlet port 221.

[0076] As can be seen from this embodiment, by setting a flow deflector 5 on the connection between the first discharge port 112 and the second inlet port 221, the polyurethane adhesive entering the homogenizing device 2 from the premixing device 1 is turbulent, thereby helping to improve the emulsification effect.

[0077] Example 5:

[0078] This embodiment provides a polyurethane adhesive homogenizing mixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
