[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. General-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.; engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate silicone, etc.; special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. Most polymers must be mixed and then granulated before they can be made into final products to become marketable raw materials.

[0003] For example, the prior art Chinese patent publication number "CN220261562U" provides a mixing device for granulating plastic particles, including a mixing mechanism and a stirring mechanism, the mixing mechanism includes a pair of support frames, the inner sides of the support frames are rotatably connected with fixed blocks, the stirring mechanism includes a box body, the two sides of the box body are respectively connected to the fixed blocks, a first bracket is fixedly installed on the upper end of the interior of the box body, a second bracket is fixedly installed on the interior of the box body near the bottom end of the first bracket, a power box is sleeved at the center of the second bracket, a first stirring shaft is rotatably connected between the bottom end of the first bracket and the upper end of the power box, a second stirring shaft is rotatably connected between the bottom end of the power box and the bottom end of the box body, and stirring blades are installed on both sides of the first stirring shaft and the second stirring shaft.

[0004] The device can effectively improve the mixing effect on plastic particles and has high practical value.

[0005] The existing mixing device for granulating plastic particles only stirs through a stirring structure, resulting in insufficient mixing of the plastic particles and uneven mixing up and down. In addition, powder debris generated by the mixing of the plastic particles will be mixed in the plastic particles, reducing the quality of the plastic particle mixture, and these powder debris cannot be separated. Utility Model Content

[0011] Furthermore, the dispersion plate is a rectangular plate structure and is horizontally arranged below the feeding pipe, and the motor is installed in the middle of the top end of the mixing barrel.

[0012] Furthermore, the sealing plug is a rubber plug, which tightly seals the discharge slot, the air inlet hole is connected to the air guide box, and the air guide box is fixed at the bottom end of the discharge barrel.

[0016] The utility model provides a mixing device for granulating plastic particles, which has the following beneficial effects:

[0017] 1. The utility model inserts a rotating rod into the mixing barrel and the lower barrel through rotation. Therefore, in the process of mixing plastic particles, the motor drives the dispersion plate and the spiral turning blade to rotate through the rotating rod, thereby stirring and dispersing the plastic particles entering the mixing barrel, and spirally turning the materials to turn and mix the plastic particles in the upper and lower parts. Moreover, air is blown into the air guide box through the blower and the air blast pipe, so as to blow air from bottom to top through the air inlet hole into the lower barrel and the mixing barrel, thereby blowing the plastic in the lower part to the upper part, and fully mixing the plastic particles through the spiral turning blades and the dispersion plate.

[0018] 2. In the process of mixing plastic particles, the utility model uses the blower to blow air toward the lower barrel and the inside of the mixing barrel through the blower pipe and the air guide box. Powder debris generated by the mixing of plastic particles is blown by the wind and discharged outward from the first air outlet and the second air outlet. After being intercepted by the interception barrel, it falls into the receiving box for collection and treatment, thereby maintaining the quality of the plastic particle mixing without mixing powder debris.
