Description

Technical Field

[0001] This utility model relates to the field of alloy mixing technology, specifically to a high-flow, decomposition-resistant PC and ABS alloy mixing device. Background Technology

[0002] High-flow, decomposition-resistant PC / ABS alloy is a modified plastic produced through precise design and preparation. It is as easy to flow and fill as water, yet as stable as rock, maintaining the strong toughness of engineering plastics. The production of high-flow, decomposition-resistant PC / ABS alloy requires compounding, necessitating the use of a twin-screw extruder. For example, a twin-screw extruder for PC-ABS alloy production (application number CN219968783U) allows PC-ABS alloy raw materials to be fed into a feeding hopper. The material is extruded under the action of helical blades. During extrusion, the feeding hopper can be opened to transport the raw material and pre-crush it. Furthermore, the feeding hopper automatically closes upon completion of production to prevent dust and other debris from falling in, improving the automation level of the device and effectively increasing the extrusion efficiency of the PC-ABS alloy raw material. However, when using this machine, all raw materials need to be crushed by the pre-crushing component in the feeding hopper. This means that most of the materials need to be crushed, and most of them are qualified-sized particles. This means that when a large amount of already qualified materials are processed repeatedly, the qualified particles will produce more and finer powder when they are repeatedly crushed and cut.

The output ends of the second motors 30 can drive the crushing roller 16 to rotate, so that the two crushing rollers 16 crush the raw material into small pieces.

[0017] A discharge pipe 17 is fixedly connected to the bottom of the crushing box 6, and a conveying cylinder 7 is fixedly connected to one side of the crushing box 6. One end of the discharge pipe 17 extends into the inside of the conveying cylinder 7. A screw conveying shaft 18 is rotatably connected inside the conveying cylinder 7 via a bearing. A first motor 19 is fixedly connected to the top of the conveying cylinder 7. The output end of the first motor 19 is connected to the top of the screw conveying shaft 18 via a coupling. A discharge pipe 20 is fixedly connected to the surface of the conveying cylinder 7. One end of the discharge pipe 20 extends into the inside of the screen box 2. The raw material inside the conveying cylinder 7 is guided into the screen box 2 through the inclined discharge pipe 20.

[0018] A top block 27 is fixedly connected to the bottom of the inner cavity of the telescopic cylinder 25. The top of the top block 27 extends to the top of the telescopic cylinder 25 and is fixedly connected to the bottom of the sieve plate 8.

Then, the telescopic end of the first electric telescopic rod 11 drives the moving block 24 and the closing plate 10 to move upward, so that the discharge channel 5 is connected to the inside of the side groove 9, so that the raw material on the surface of the screen plate 8 is discharged into the crushing box 6 through the side groove 9, the discharge channel 5 and the feed channel 15. The output end of the second motor 30 drives the crushing roller 16 to rotate, so that the two crushing rollers 16 crush the larger raw materials, and then enter the conveying cylinder 7 through the discharge pipe 17. Then, the output end of the first motor 19 drives the spiral conveying shaft 18 to rotate, so that the raw material inside the conveying cylinder 7 enters the screen box 2 through the discharge pipe 20, is screened and then enters the screen box 2.
