Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a mixing device for producing modified plastic particles. Background Technology

[0002] Mixing in the production of plastic pellets is a key step in ensuring product quality. Its purpose is to uniformly mix components such as resin, additives, and fillers to improve the performance and consistency of plastics. At the same time, when modifying pellets, plastics and additives with different properties are also mixed.

[0003] When mixing different plastic granules, the granules are either poured into the mixing tank simultaneously or one by one. However, regardless of the method of pouring, the different particles are separated in the mixing tank. Pouring them one by one will result in different particles being layered, while pouring them from different positions in the mixing tank at the same time will cause them to accumulate on both sides of the mixing tank. Before stirring and mixing, the purpose of premixing cannot be achieved, which leads to a longer mixing time to fully mix them evenly, resulting in relatively slow overall efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for producing modified plastic particles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a mixing chamber, with an upper cover rotatably connected to the upper end of the mixing chamber. A pair of feed pipes are fixed on the upper cover. A material box is fixed on the upper end of the upper cover at a position corresponding to the feed pipes. A drive shaft is rotatably connected inside the mixing chamber. A stirring rod is fixed on the drive shaft. A drive motor for rotating the drive shaft is fixed at the bottom of the mixing chamber. A discharge pipe is fixed at the bottom of the mixing chamber. A rotating assembly is provided between the upper outer end of the mixing chamber and the upper cover.

[0006] Preferably, the rotating assembly includes a servo motor and a fixed gear. The fixed gear is fixed to the outside of the upper cover, the servo motor is fixed to the upper outside of the mixing chamber, and a drive gear is fixed to the output end of the servo motor. The drive gear meshes with the fixed gear.

[0007] Preferably, an annular sleeve is fixed at the bottom of the upper cover, the annular sleeve is located inside the mixing chamber and is rotatably connected to the inner side wall of the mixing chamber via a bearing, a connecting sleeve is rotatably connected at the center position of the bottom of the upper cover, and the upper end of the drive shaft is located inside the connecting sleeve.

[0008] Preferably, a fixing frame is fixed to the upper end of the upper cover, and the material box is fixed on the fixing frame.

[0009] Preferably, both the discharge pipe and the feed pipe are equipped with electromagnetic gate valves, the drive shaft is fixed with a scraper, the bottom of the scraper abuts against the inner wall of the bottom of the mixing tank, and the scraper has an arc structure.

[0010] Preferably, a support frame is fixed to the bottom of the mixing box, and an electrical control box is installed on the outer wall of the mixing box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when feeding multiple particles, the rotation of the upper cover can be used to stack different particles in an alternating manner, achieving preliminary mixing before mixing, avoiding stratification or complete separation of different particles when feeding through a fixed feed inlet, thereby improving the mixing speed and shortening the mixing time.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a mixing box 1, an upper cover 3 rotatably connected to the upper end of the mixing box 1, a pair of feed pipes 31 fixed on the upper cover 3, a material box 4 fixed on the upper end of the upper cover 3 and at a position corresponding to the feed pipes 31, a drive shaft 2 rotatably connected inside the mixing box 1, a stirring rod 21 fixed on the drive shaft 2, a drive motor 22 fixed at the bottom of the mixing box 1 to drive the drive shaft 2 to rotate, a discharge pipe 11 fixed at the bottom of the mixing box 1, a rotating assembly provided between the upper end of the outer side of the mixing box 1 and the upper cover 3, a support frame fixed at the bottom of the mixing box 1, and an electrical control box installed on the outer wall of the mixing box 1.

[0019] The rotating assembly includes a servo motor 5 and a fixed gear 33. The fixed gear 33 is fixed on the outside of the upper cover 3, and the servo motor 5 is fixed on the upper outside of the mixing box 1. A drive gear 51 is fixed at the output end of the servo motor 5, and the drive gear 51 meshes with the fixed gear 33.

[0020] An annular sleeve 35 is fixed to the bottom of the upper cover 3. The annular sleeve 35 is located inside the mixing box 1 and is rotatably connected to the inner side wall of the mixing box 1 through a bearing. The rotation of the annular sleeve 35 allows the upper cover 3 to rotate stably. A connecting sleeve 34 is rotatably connected to the center of the bottom of the upper cover 3. The upper end of the drive shaft 2 is located inside the connecting sleeve 34. The upper cover 3 and the drive shaft 2 are connected by the connecting sleeve 34, allowing the upper cover 3 and the drive shaft 2 to rotate independently. A fixing frame 32 is fixed to the upper end of the upper cover 3, and the material box 4 is fixed on the fixing frame 32.

[0021] Electromagnetic gate valves are installed on both the discharge pipe 11 and the feed pipe 31. A scraper 23 is fixed on the drive shaft 2. The bottom of the scraper 23 abuts against the inner wall of the bottom of the mixing box 1. The scraper 23 has an arc structure.

[0022] Working principle: First, connect the entire device to an external power source. Then, pour different plastic granules into the material box 4 according to a predetermined ratio. When feeding, the solenoid valve on the feed pipe 31 can be opened, and the upper cover 3 can be rotated. Different granules will rotate and fall into the mixing box 1, and the different granules will be staggered and superimposed to achieve the purpose of premixing. When the drive motor 22 drives the drive shaft 2 and the stirring rod 21 to rotate, the different granules can be mixed evenly more easily, thereby improving efficiency. Secondly, when driving the rotation of the upper cover 3, the output end of the servo motor 5 can drive the drive gear 51 to rotate, and the transmission of the fixed gear 33 can drive the upper cover 3 to rotate. When discharging, the solenoid valve on the discharge pipe 11 can be opened to discharge, and at the same time, the drive shaft 2 is rotated to drive the scraper 23 to rotate, pushing the granules at the bottom to the discharge pipe 11, avoiding the residue of granules in the mixing box 1.
