DETAILED DESCRIPTION

[0016] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0017] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0018] like Figure 1-2 As shown, in this embodiment, the extruder feeding device for mixing the agricultural film raw material and the masterbatch comprises a first feeding mechanism, a second feeding mechanism and a mixing mechanism;

[0019] The first feeding mechanism comprises a first conveying auger 1, the feed port of the first conveying auger 1 is connected to a masterbatch hopper 2, and a guide pipe 3 is provided below the discharge port of the first conveying auger 1 to form a masterbatch discharge channel for separating the raw materials; the second feeding mechanism comprises a second conveying auger 4 for feeding the extruder, the feed port of the second conveying auger 4 is connected to a raw material hopper 6 through a mixing pipe 5, the guide pipe 3 is vertically arranged at the center of the raw material hopper 6 to ensure that the subsequent masterbatch can be evenly mixed into the raw material, and the lower end of the guide pipe 3 extends to the mixing pipe 5; the mixing The material mechanism is arranged in the mixing tube 5, which includes a first umbrella cover 7 arranged below the guide tube 3. The bottom of the first umbrella cover 7 is connected to a motor 8, and the motor 8 is fixed in the mixing tube 5 through a first bracket 9. The outer periphery of the lower end of the guide tube 3 is connected to a second umbrella cover 10, and the edge of the second umbrella cover 10 extends out of the edge of the first umbrella cover 7. A masterbatch outlet is formed between the second umbrella cover 10 and the first umbrella cover 7, and a raw material outlet is formed between the second umbrella cover 10 and the mixing tube 5. The bottom periphery of the first umbrella cover 7 is connected to a protective shell 11, and a plurality of stirring teeth 12 are distributed on the outer periphery of the protective shell 11.

[0020] During production, masterbatch is added to the masterbatch hopper 2, and the masterbatch feeding speed is controlled by the first conveying auger 1; raw materials are added to the raw material hopper 6, and the raw material feeding speed can be controlled by the second conveying auger 4. The material guide tube 3 is set to separate the raw materials so that the masterbatch is mixed with the raw materials only after it reaches a specific position, which alleviates the color difference problem caused by different feeding speeds. After the masterbatch reaches a certain position, the first umbrella cover 7 driven by the motor 8 can disperse the masterbatch to the periphery, and the second umbrella cover 10 is set in conjunction with the first umbrella cover 7, which will facilitate the masterbatch to be smoothly thrown into the peripheral raw materials by the first umbrella cover 7 to avoid masterbatch concentration.
