Manufacturing method of mixing device for TPU polyurethane and various drawing film products

1. The utility model relates to the technical field of tpu production equipment, in particular to a mixing device of tpu polyurethane and a variety of drawn film products.

Background technique:

2. In tpu production, the materials of each component need to be transported to the mixing device for mixing, so that the materials are evenly mixed before proceeding to the next step. The existing mixing device is either a three-blade or two-blade agitator , All are rotated in the horizontal direction for mixing. Most of the materials move and mix on the horizontal surface, and a small part of the materials will move and mix longitudinally. In general, the overall mixing speed of the materials is slow, especially for a variety of materials that are easy to layer. The effect is deposited at the bottom, resulting in low mixing efficiency.

3. After searching, the Chinese patent application number cn201921434653.5 discloses a mixing device for tpu film production. A cover cylinder and a vibration motor are fixedly installed in the middle, and the vibration motor is located inside the cover cylinder. The output end of the vibration motor is fixedly installed with a mixing barrel. However, the above technical solution does not have a corresponding device for filtering production materials. Therefore, there is also the problem that the raw materials cannot be effectively filtered before mixing the raw materials.
