Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of TPU colored films, and in particular relates to a colored film particle stirring and extruding device. Background Art
[0002] Colored film is a film made of multiple materials. Its preparation methods include dry compounding, wet compounding, extrusion compounding, hot melt compounding and co-extrusion compounding. The number of layers can be 2-8.
[0003] In the production process of traditional colored films, the base film is usually made first. After the base film is made, the glare layer and the base material are laminated together with hot-melt resin to achieve multi-layer lamination. However, this lamination method has a layer of hot-melt resin between the two. After long-term use, the hot-melt resin in the middle layer will turn yellow, causing the entire colored film to turn yellow, thus affecting the appearance. Summary of the Invention

[0014] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.
[0015] Example: A device for stirring and extruding colored film particles, such as Figure 1-Figure 3As shown, it includes a feeding assembly, a stirring and heating roller group and an extrusion die 14. The feeding assembly is arranged on the upper side of the extrusion die 14. The feeding assembly includes two feeding hoppers 1. The feeding hopper 1 includes a horizontal discharge port 2 at the bottom. The horizontal discharge port 2 includes a discharge chute 3. A vibration motor 4 is provided at the bottom of each feeding hopper 1. The stirring and heating roller group includes a stirring roller 5, a stirring motor 6, an internal stirring roller 7, a heating and extrusion roller 8, an extrusion motor 9 and an extrusion screw 10. The heating and extrusion roller 8 is arranged on the right side of the stirring roller 5, and the interiors of the two are connected to each other. Two receiving hoppers 11 are provided on the top of the stirring roller 5, and the two receiving hoppers 11 are respectively aligned with the discharge chutes 3 of the two lower hoppers 1. The stirring motor 6 is provided at the left end of the stirring roller 5, and the internal stirring roller 7 is provided inside the stirring roller 5 and fixedly connected to the drive shaft of the stirring motor 6. The extrusion screw 10 is provided on the right side of the heated extrusion roller 8, and the extrusion screw 10 is provided inside the heated extrusion roller 8 and fixedly connected to the drive shaft of the extrusion motor 9. The heated extrusion roller 8 includes a discharge port 12, and the discharge port 12 is communicated with the extrusion die head 14.
