Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plastic production, and particularly relates to a raw material mixing device for modified plastic production. BACKGROUND

[0002] Plastic refers to a plastic (flexible) material or a rigid material formed by curing and cross-linking, which is mainly composed of synthetic resins with high molecular weight, and is added with appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, colorants and the like.

[0003] At present, in the processing and production of plastic parts, it is often necessary to mix multiple plastics uniformly and then perform hot melt extrusion operation. The traditional method is generally to complete the mixing operation by using a stirrer for direct stirring operation, or to use manual operation, and the manual operation method directly uses a stirring rod for stirring. The above-mentioned methods all need to place the material in a container and then mix the raw material, and need manpower or external energy as driving energy, and the stirring and mixing efficiency is low and the mixing uniformity is poor. SUMMARY

[0004] Based on the problems mentioned in the above background technology, the application provides a raw material mixing device for modified plastic production, which is used to solve the problems that the existing plastic raw material mixing device needs external driving energy, the mixing efficiency is low, and the mixing uniformity is poor. The technical scheme adopted by the application is as follows:

[0005] A raw material mixing device for modified plastic production, the raw material mixing device comprises a dispersing assembly, a material guiding assembly and a mixing assembly which are fixedly connected, the dispersing assembly comprises a first base cylinder and a plurality of dispersers, the first base cylinder is provided with a base frame and a first mounting table, the dispersers are mounted on the first mounting table, the disperser comprises a first material guiding cylinder and a feeding hopper which are fixedly connected, the first material guiding cylinder is uniformly provided with a first dispersing column, the first material guiding cylinder is provided with a first mounting plate, the first mounting plate is provided with a first connecting column, the first connecting column penetrates the first mounting table, the first connecting column is sleeved with a first spring, the first spring is located between the first mounting table and the first mounting plate, the material guiding assembly comprises a second base cylinder, the second base cylinder is provided with a second material guiding cylinder, the second material guiding cylinder and the second base cylinder are provided with a connecting rod, the second material guiding cylinder is provided with a collecting hopper, the outlet of the first material guiding cylinder is located in the collecting hopper, the second material guiding cylinder is provided with a material guiding spiral, the mixing assembly comprises a third base cylinder, the third base cylinder is provided with a second mounting table, the second mounting table is provided with a mixer, the mixer comprises a third material guiding cylinder, the second material guiding cylinder is located in the third material guiding cylinder, and the third material guiding cylinder is provided with a second dispersing column.

[0006] On the basis of the above technical scheme, the application further makes the following improvements:

[0007] Furthermore, the first and second dispersion columns are triangular prisms. Increasing the contact area between the first and second dispersion columns and the raw material increases the force on the first guide cylinder when the raw material impacts the first and second dispersion columns, thereby increasing the deformation of the first spring. This helps to increase the oscillation amplitude of the first guide cylinder, avoid raw material blockage, and enhance the raw material dispersion effect.

[0008] Furthermore, two adjacent first guide cylinders are arranged in a Y-shape. This improves space utilization and allows for better placement of the feed hopper for easier material feeding.

[0009] Furthermore, a top cover is installed on the first base cylinder, and a reserved slot corresponding to the feed hopper is opened on the top cover, where the material storage is located. The top cover covers the gap between the feed hopper and the first base cylinder to prevent debris from falling into the first base cylinder and mixing with the raw materials.

[0010] Furthermore, the third guide cylinder is provided with a second mounting plate, on which a second connecting column is mounted. A through hole is formed on the second mounting plate, and the second connecting column passes through the through hole. The gap between the second connecting column and the through hole ranges from 1mm to 3mm. A bearing ring and a second spring are sleeved on the second connecting column, with the second spring located between the bearing ring and the second mounting plate. When the raw material falls and impacts the second dispersing column, the third guide cylinder vibrates under the action of the second spring, improving the mixing effect of the raw material. Simultaneously, the relatively large gap between the second connecting column and the through hole allows the third guide cylinder to sway, which is beneficial for improving the vibration effect.

[0011] Furthermore, the third feed cylinder is equipped with a collecting plate. The collecting plate concentrates the raw materials falling from the feed screw towards the center of the third feed cylinder, where they are then dispersed and mixed by the second dispersing column, thereby improving the uniformity of mixing between different raw materials.

[0012] Furthermore, a main lug plate is installed on the second base cylinder, and auxiliary lug plates are installed on both the first and third base cylinders. The first and third base cylinders are bolted to the main lug plate on the second base cylinder via the auxiliary lug plates. The disassembly and installation of the material guiding assembly and the mixing assembly are relatively convenient, facilitating maintenance.

[0013] The beneficial effects of this invention are:

[0014] 1. Different raw materials can be dispersed and sprinkled through the dispersion component. The dispersed raw materials enter the second guide cylinder for initial mixing. Finally, the second dispersion column in the third guide cylinder distributes the initially mixed raw materials, so that the different raw materials are evenly mixed and the mixing effect between different raw materials is better.

[0015] 2. Different raw materials are placed in different feeding hoppers and naturally dropped to achieve the purpose of mixing, wireless stirring mechanism is set, driving energy is not needed to be set, use is more convenient, energy saving, and mixing efficiency is high.
