Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic mixing device. Background Art

[0002] Polymer plastics are a type of plastics composed of polymer compounds, which have the characteristics of long molecular chains and large structures. Polymer plastics usually have excellent properties such as good mechanical properties, wear resistance, chemical corrosion resistance, insulation and heat resistance, and are widely used in various fields. When plastic materials are molded, it is often necessary to add a number of modified raw materials or other materials. In order to ensure its performance, it is necessary to require the uniformity of its material mixing. A plastic mixer is disclosed in the prior art, application number: CN202222928778.1. In order to solve the problem that the mixer cannot crush large pieces of plastic raw materials, the plastic raw materials are bonded into blocks, which will affect the mixing effect, and the plastic raw materials will adhere to the inner wall of the mixer, which will affect the mixing effect. By setting a crushing roller group, the crushing roller group can crush the plastic raw materials bonded into blocks, which can improve the mixing effect. However, there will still be solid bodies in the crushed block plastic raw materials. In the subsequent mixing, it is necessary to extend the mixing time to completely break them. Therefore, the inventor proposes a plastic mixing device. Utility Model Content

The mixing box is arranged below the processing box. A filling pipe is fixedly connected to the upper surface of the crushing box. A material distribution mechanism is installed inside the processing box. The material distribution mechanism includes a driving frame and a screening mesh plate. The screening mesh plates are symmetrically distributed on the upper and lower sides of the driving frame. The insides of two groups of the screening mesh plates are respectively fixedly connected with support rods, and the surfaces of the support rods facing the driving frame are fixedly connected with driven rods. Two groups of crushing shafts are rotatably installed inside the crushing box. Crushing knives are arranged on the outer walls of the crushing shafts. Gears are fixedly connected to the ends of the crushing shafts. The gears on the two groups of crushing shafts are meshed with each other, and one of the gears is connected to a motor. Thanks to the setting of the material distribution mechanism, the crushed plastic raw materials can be continuously shaken, and the raw material groups that continue to bond will be gradually dispersed by the shaking, and pass through the screening mesh plate to fall into the mixing box, thereby accelerating the subsequent mixing quality of the plastic raw materials.

[0012] In the above scheme, thanks to the setting of the material dividing mechanism, the crushed plastic raw materials can be continuously shaken, and the raw material clumps that are still sticking together will be gradually dispersed by the shaking, and fall through the screening mesh plate into the mixing box, thereby accelerating the subsequent mixing quality of the plastic raw materials and making the mixed molding of the plastic raw materials faster. The screening mesh plate cooperates with the driving frame, and the mutual contact between the driving rod and the driven rod achieves the effect of reciprocating motion of the screening mesh plate. The principle is simple and easy to implement, and can be widely promoted. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The working principle provided by the utility model is that when in use, the agglomerated plastic raw materials are first added from the inside of the filling pipe 7, and then the motor drives the gear 18 to rotate, and the two sets of gears 18 are meshed with each other, driving the two sets of crushing shafts 19 to rotate relative to each other, and then the crushing knives 17 on the outer wall crush the agglomerated plastic raw materials, and then the plastic raw materials fall into the surface of the screening mesh plate 12, and the driving cylinder 10 drives the driving frame 14 to move by telescoping, and the driving rod 13 on the outer wall of the driving frame 14 moves accordingly.
