[0002] Plastic masterbatch is composed of excess chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading an excess amount of pigments (dyes) in the resin. Masterbatch refers to the granular material obtained by mixing and kneading various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then metering, mixing, melting, extruding and pelletizing by extruders and other equipment. It needs to be dried by drying equipment during the production process of masterbatch. A certain degree of dryness must be guaranteed when masterbatch is used. Masterbatch with insufficient dryness will have a huge impact on subsequent production processes.

[0003] The utility model with the existing authorization announcement number CN202023142333.8 discloses a plastic masterbatch drying equipment. The above-mentioned technical scheme is adopted, and an air outlet is set on the connecting rod. The masterbatch is blown dry while being stirred. The masterbatch is heated evenly, which can ensure that the masterbatch has good dryness and prevent the masterbatch from agglomerating. However, in the above-mentioned technical scheme, when the masterbatch is stirred, the masterbatch is easy to adhere to the inner wall surface of the stirring equipment, resulting in uneven drying of the masterbatch and poor drying and mixing effect, which has certain limitations.

[0004] Therefore, we propose a drying equipment for the production of plastic masterbatch to solve the above problems. Utility Model Content

[0024] A blocking plate 22 is clamped inside each blanking port 25, a bottom cover 9 is clamped on the outer surface of the drying box 4, the upper surface of the bottom cover 9 is fixedly connected to the bottom surfaces of the two blocking plates 22, the inner wall of the bottom cover 9 and the inner wall of the drying box 4 are threadedly connected with two groups of fixing bolts 23, the inner top wall of the mixing cylinder 16 is fixedly connected with a first bearing 21, two groups of exhaust pipes 3 are fixedly connected to the inner wall of the drying box 4, and three exhaust fans 13 are fixedly connected to the inner wall of each group of exhaust pipes 3, and the controller 8 is electrically connected to the two groups of exhaust fans 13 through wires. By providing the exhaust pipes 3 and the exhaust fans 13, the internal heat of the drying box 4 can be reduced, thereby facilitating heat dissipation.

[0025] The inner ring of the first bearing 21 is fixedly connected with a stirring shaft 18, the top end of the stirring shaft 18 passes through the mixing barrel 16 and extends to the top of the mixing barrel 16, the outer surface of the stirring shaft 18 is fixedly connected with a plurality of identical connecting shafts 20, the upper surface of the mixing barrel 16 is fixedly connected with an exhaust pipe 6, the inner wall of the exhaust pipe 6 is fixedly connected with an exhaust fan 15, the controller 8 is electrically connected to the exhaust fan 15 through a wire, and by providing the exhaust pipe 6 and the exhaust fan 15, it is possible to conveniently extract the hot air inside the mixing barrel 16, reduce moisture, and facilitate use.

[0026] The ends of the four connecting shafts 20 that are away from each other are all fixedly connected to a scraper 19, the top of the stirring shaft 18 is fixedly connected to a stepping motor 14, the left side of the drying box 4 is fixedly connected to a controller 8, the inner wall of the mixing barrel 16 is fixedly connected to a second bearing 17, and the inner ring of the second bearing 17 is fixedly connected to the outer surface of the stirring shaft 18. By providing the second bearing 17, the rotation stability of the stirring shaft 18 can be conveniently increased, and the use effect can be effectively increased.

[0027] The controller 8 is electrically connected to the heating wire 11 and the stepper motor 14 through wires, and two auxiliary handles 24 are fixedly connected to the outer surface of the bottom cover 9. The outer surface of the stepper motor 14 and the upper surface of the mixing barrel 16 are jointly fixedly connected with a bracket 5. By providing the auxiliary handles 24, the bottom cover 9 can be easily disassembled, and by providing the bracket 5, the stepper motor 14 can be easily supported.

[0028] The working principle of the utility model is as follows: when in use, the stepper motor 14, the heating wire 11, the exhaust fan 13 and the exhaust fan 15 are first connected to the power supply, the sealing door 7 can be opened first to put the plastic masterbatch into the mixing barrel 16, and then the heating wire 11 is started. The heat generated by the heating wire 11 is discharged to the surface of the mixing barrel 16 through the through hole on the isolation barrel 12, and the plastic masterbatch inside the mixing barrel 16 can be dried. When the stepper motor 14 is started, the stepper motor 14 can directly drive the stirring shaft 18 to rotate inside the first bearing 21, and the stirring shaft 18 first drives the plastic masterbatch to rotate and stir, and then the stirring shaft 18 drives the scraper 19 to the mixing barrel 16 through the connecting shaft 20.

The dried plastic masterbatch falls into the inside of the receiving box through the drop port 25, which prevents the plastic masterbatch from easily adhering to the inner wall surface of the stirring equipment, resulting in uneven drying of the masterbatch.
