Detailed Description of the Preferred Embodiment

[0017] The following will Figures 1 to 4 describe the present utility model in detail with reference to the attached

[0018] A rotatable flow divider structure of a plastic extruder of the utility model comprises an extrusion pipe 1 and a flow divider 2. A mixing channel 11 is arranged inside the extrusion pipe 1. One end of the extrusion pipe 1 is provided with a connecting ring 3, and a first clamping groove 31 is arranged on the inner wall of the connecting ring 3. An outlet channel 21 communicating with the mixing channel 11 is arranged inside the flow divider 2. Materials are fused in the mixing channel 11 and then extruded through the outlet channel 21. One end of the flow divider 2 is provided with a clamping ring 22 movably connected with the first clamping groove 31, which enables the flow divider 2 to be movably connected with the extrusion pipe 1. A second clamping groove 23 is arranged on the inner wall of the flow divider 2, and a filter 24 is arranged in the second clamping groove 23. The filter 24 is arranged in the outlet channel 21. A plurality of laterally extending outlet ports 25 are arranged on the flow divider 2. The outlet ports 25 communicate with the outlet channel 21. After being filtered by the filter 24, the materials are discharged from the outlet ports 25. A threaded portion 251 is arranged on the outlet port 25, and the outlet port 25 can be flexibly connected with various injection molding devices in a threaded connection manner. A turntable 26 is arranged at the end of the flow divider 2. By operating the turntable 26, the flow divider 2 can be rotated 360°, which is convenient for adjusting the direction of the outlet ports 25. The structure is simple and easy to use.

[0019] The flow divider 2 is provided with a first connecting portion 4 and a second connecting portion 5, and the first connecting portion 4 and the second connecting portion 5 are detachably connected. The first connecting portion 4 is provided with a third clamping groove 41 movably connected with the end of the connecting ring 3. In this solution, the flow divider 2 is composed of two components, namely the first connecting portion 4 and the second connecting portion 5. Among them, the clamping ring 22 and the second clamping groove 23 are both arranged on the first connecting portion 4, and the first clamping portion is connected with the connecting ring 3; the outlet ports 25 and the turntable 26 are both arranged on the second connecting portion 5, and the second connecting portion 5 is threadedly connected with the first connecting portion 4. By screwing the second connecting portion 5, the second connecting portion 5 can be separated from the first connecting portion 4, which is convenient for cleaning and maintaining the inside of the flow divider 2. At the same time, different-shaped and -sized second connecting portions 5 can also be replaced to meet the use requirements.

[0020] An annular protrusion 51 is arranged on the outside of the second connecting portion 5, and a limiting block 42 for fixing the annular protrusion 51 is arranged on the outside of the first connecting portion 4. After the limiting block 42 abuts against and fixes the annular protrusion 51, the second connecting portion 5 is fixed. When the turntable 26 is rotated, the flow divider 2 can rotate as a whole, and the stability is high.

[0021] The annular protrusion 51 is made of rubber material. The surface of the annular protrusion 51 made of rubber material has a high frictional resistance, and it is not easy to slip after the limiting block 42 abuts against the annular protrusion 51.

[0022] A fixing block 43 is arranged outside the first connecting part 4, and an adjusting bolt 44 for adjusting the position of the limiting block 42 is arranged on the fixing block 43. By screwing the adjusting bolt 44, the limiting block 42 can move up and down, and the second connecting part 5 is convenient to disassemble and install, and the operation is simple.

[0023] The filter 24 is provided with a filter screen 241. The filter screen 241 can screen out larger particles and impurities in the material, improving the quality and stability of the discharged material. After the staff removes the second connecting part 5, the filter screen 241 can be taken out by tools such as pliers, which is convenient for cleaning or replacing the filter screen 241.
