[0001] This utility model relates to the technical field of drying and mixing devices for injection molding machines, specifically a drying and mixing device suitable for injection molding machines. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] The drying and mixing device of an injection molding machine is an important piece of equipment for processing plastic raw materials. Its main function is to dry and mix plastic granules to ensure a uniform material flow and good finished product quality during the injection molding process. However, traditional drying and mixing devices are often complex in structure and have poor drying effect on materials, resulting in moisture in subsequent injection molding production and poor quality of injection molded products. Therefore, we propose a drying and mixing device suitable for injection molding machines. Utility Model Content

The drying cylinder 1 has four axially symmetrically distributed connecting holes 12 on one end face corresponding to the hot air devices 2, and the hot air device 2 has connecting holes 15 on one end face corresponding to the drying cylinder 1, which are fixedly connected to the connecting holes 12 by adapter screws. The heating element 5 and the fan assembly 6 are provided inside the hot air device 2. The protective net 4 is provided on the end face of the hot air device 2 facing away from the drying cylinder 1. The power device 3 is provided inside the drying cylinder 1, and mating holes 21 are provided at both ends of the drying cylinder 1 corresponding to the power device 3.

[0023] Furthermore, the drying cylinder 1 is an axisymmetric structure with a hollow interior, and a circular cylinder 8 is provided inside the drying cylinder 1. A set of equidistant air vents 9 are opened on the cylindrical side of the circular cylinder 8. An air inlet 11 is opened on the end face of the drying cylinder 1 corresponding to the hot air device 2, and a connection hole 12 is opened at each of the four corners of the air inlet 11. A feed inlet 7 is provided on the end face of the drying cylinder 1 corresponding to the rectangular horizontal plane, and the feed inlet 7 is connected to the interior of the circular cylinder 8. A discharge outlet 10 is opened on the end face of the circular cylinder 8 opposite to the feed inlet 7, and support rods are provided at the four corners of the end face of the drying cylinder 1 opposite to the feed inlet 7. The air vents 9 opened on the cylindrical side of the circular cylinder 8 facilitate the circulation of water vapor and hot air, and improve the drying efficiency.

[0024] Furthermore, the hot air device 2 is provided with a connecting plate 14 on one end face corresponding to the drying cylinder 1, and the four corners of the connecting plate 14 are provided with connecting holes 15. The end face of the hot air device 2 away from the drying cylinder 1 is provided with a rectangular opening that is connected to the protective net 4. The interior of the hot air device 2 is provided with two axially symmetrically distributed connecting blocks 13. The end face of the hot air device 2 corresponding to the protective net 4 is provided with three equally spaced mating chambers 16 that are connected to the fan assembly 6. The overall structure of the hot air device 2 is symmetrically arranged, which facilitates the correct flow of internal hot air and improves the drying quality.

[0025] Furthermore, the heating element 5 is composed of connecting block 2 17 and heating wire 18. The heating element 5 is provided with connecting block 2 17 at both ends corresponding to the hot air device 2, which is connected to connecting block 1 13. Three heating wires 18 are provided between the two connecting blocks 2 17 in an equidistant manner.

[0026] Furthermore, the power unit 3 consists of two parts: a motor 19 and a rotating pusher 20. The rotating pusher 20 is connected to the inside of the drying cylinder 1.

[0028] Working Principle: The drying and mixing device suitable for injection molding machines is correctly installed according to the diagram. Specifically, two hot air devices 2 are symmetrically distributed on both sides of the drying cylinder 1 via screws. Each hot air device 2 contains a heating element 5 and a fan assembly 6. Protective nets 4 are installed at opposite ends of each hot air device 2. When the drying and mixing device is connected to an external power source and started, the power unit 3 begins to work. The output shaft of the motor 19 drives the rotating pusher 20 to rotate uniformly inside the circular cylinder 8 of the hot air device 2. The heating element 5 and fan assembly 6 inside the hot air device 2 also begin to work. The fan assembly 6 draws in external air, which is effectively filtered by the protective net 4. The heating element 5 then heats the air. External equipment begins to feed material through the inlet 7 at the top of the drying cylinder 1. The material is tumbled and moved by the rotating pusher 20, while the hot air generated inside the hot air device 2 dries the moving material. The dried material flows out through the outlet 10, thus completing the drying process.
