[0001] The utility model relates to a stirring and mixing device, in particular to a stirring and mixing device for plastic powder raw materials, belonging to the technical field of plastic powder production. Background Art

[0002] Plastic powder is originally colorless or yellow-brown transparent. It is often sold in the market with colorants to appear red, yellow, black, green, brown, blue and other colors. It is available in granules or powder. It is resistant to weak acids and weak bases, decomposes in strong acids, corrodes in strong bases, is insoluble in water, soluble in organic solvents such as acetone and alcohol, and is obtained by condensation of phenol and formaldehyde.

[0003] During the production process of plastic powder, different additives need to be added to the raw materials for mixing to facilitate subsequent production. However, the current mixing equipment for the production of plastic powder raw materials directly pours all the raw materials into the equipment for mixing. This can easily cause accumulation, resulting in insufficient mixing. In addition, during the material feeding process, manual labor is required to continuously add raw materials, which increases the manual pulling strength and makes material feeding very inconvenient.

[0021] A feeding pipe 18 is fixedly connected to the middle of the bottom end of the mixing box 1, and an electric valve is fixedly installed on the pipe wall of the feeding pipe 18 near the lower end, which is conducive to convenient feeding after the later mixing is completed through the feeding pipe 18 with the electric valve.

[0022] The outer box walls on both sides of the lower end of the mixing box 1 are fixedly connected with symmetrically arranged support feet 19, which is conducive to stably supporting the mixing box 1 through the support feet 19.

[0023] An L-shaped plate is fixedly connected to the upper end of the driving motor 2, and the lower end of the L-shaped plate is fixedly connected to the outer box wall of the mixing box 1, which is beneficial to conveniently increase the supporting stability of the driving motor 2 through the L-shaped plate and facilitate the use of the driving motor 2.

[0024] Working principle: During use, when producing plastic powder, when the plastic powder raw materials need to be mixed, the plastic powder raw materials are injected into the storage tube 8 respectively. After the injection is completed, the electric telescopic rod 14 is started by an external power supply, and the output end of the electric telescopic rod 14 pushes the horizontal plate 13. When the horizontal plate 13 rises, it drives the vertical rod 11. The vertical rod 11 rises stably under the sliding limit action of the slide groove 9 and the slide rod 10. At the same time, when the vertical rod 11 rises, it will drive the baffle 12 to move from the bottom end of the conical tube 7 to the upper end of the conical tube 7. At this time, the gap generated by the conical tube 7 will inject the plastic powder raw materials into the open tube 6 through the conical tube 7. At the same time, the vertical rod 11 drives the baffle 12 to descend to limit the conical tube 7, which is convenient for multiple unloading in the later stage. At this time, the vertical rod 11 is started. The driving motor 2 is driven, and the output end of the driving motor 2 drives the first rotating rod 3 to rotate through the bearing. When the first rotating rod 3 rotates, it drives the first bevel gear 4 and the support rod 5 to rotate. The support rod 5 will continuously drive the open tube 6 to rotate. When the raw materials inside the open tube 6 rotate, they are discharged from the through hole at the bottom to avoid accumulation and facilitate later mixing. In addition, the first bevel gear 4 is engaged to drive the second bevel gear 16 to rotate. The second bevel gear 16 is forced to cooperate with the bearing to stably drive the second rotating rod 15 to rotate. The second rotating rod 15 will stably drive several mixing rods 17 to rotate. The mixing rods 17 will quickly mix the plastic powder raw materials at the bottom of the mixing box 1. After mixing, the electric valve on the discharge pipe 18 is opened to discharge the materials, which is convenient for subsequent use.
