Technical Field

[0001] This utility model relates to the field of melt flow divider technology, specifically a pre-treatment melt flow divider. Background Technology

[0002] A melt distributor is a functional structural component installed in polymer material processing equipment (such as extruders, injection molding machines, or die head systems). It is mainly used to distribute the molten polymer (i.e., melt) entering from the feed pipe, regulate the flow rate, perform preliminary filtration, and control the temperature, so as to achieve uniform and efficient distribution of the melt in subsequent processing steps.

[0003] In the extrusion or injection molding process of polymer melts, the uniform distribution of melt and impurity control in existing melt manifolds are key factors affecting product quality and mold life. Traditional melt manifold structures generally only have basic flow guiding functions and lack effective filtering devices, which can easily lead to insufficiently plasticized particles or foreign matter entering the die head area, thereby causing mold blockage, product defects, or production interruption.

[0004] Therefore, it is necessary to design a pre-treatment melt diverter to solve the above problems. Utility Model Content

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a pretreatment melt diversion plate, including an upper diversion plate 1 and a lower diversion plate 2 threadedly connected to the upper diversion plate 1. Connecting pieces 3 are fixedly connected to both sides of the upper diversion plate 1 and the lower diversion plate 2, and two connecting pieces 3 on the same side are connected by bolts. Both the upper diversion plate 1 and the lower diversion plate 2 have two interconnected second diversion ports 15 on the same side inside. Threaded insertion blocks 20 are threadedly inserted into both sides of the two second diversion ports 15 at the bottom of the upper diversion plate 1, and all four threaded insertion blocks 20 are threadedly sleeved. There are mounting panels 18, and a filter plate 19 is fixedly connected between two mounting panels 18 on the same side. The tops of the two second diversion ports 15 on the diversion upper plate 1 are connected to guide pipes 13. A diversion block 5 is fixedly connected to the top of the diversion upper plate 1, and a first diversion port 12 is opened inside the diversion block 5. The top of the guide pipe 13 is connected to the bottom of the first diversion port 12. A feed pipe 6 is connected to the top of the first diversion port 12, and a fixing ring 7 is fixedly sleeved on the outer surface of the feed pipe 6. Each of the fixed rings 7 has a screw 8 threadedly inserted into it, and the bottom of each screw 8 is rotatably connected to a partition plate 11. A knob 9 is fixedly connected to the top of each screw 8. The melt enters the flow divider block 5 through the feed pipe 6, and is divided through the first flow divider port 12. The melt is then fed into the two second flow divider ports 15 through two guide pipes 13 for further flow division. During the flow division process, impurities inside the melt are filtered by two filter plates 19, preventing insufficient plasticization or foreign matter from entering the subsequent die head. This extends mold life and reduces quality defects such as blockage and flow marks. At the same time, by rotating the two knobs 9, the position of the two partition plates 11 inside the first diversion port 12 can be adjusted, thereby selecting whether to close a single diversion channel on the diversion block 5, so that only one second diversion port 15 on the lower diversion plate 2 is used for diversion, improving the adaptability of the device body. Furthermore, by disassembling and assembling the two filter plates 19, the filter plates 19 can be easily cleaned, improving the efficiency of the device and avoiding the reduction of the diversion efficiency of the device after long-term use.

[0021] To improve the sealing performance of the partition plate 11 sliding on the diversion block 5, two symmetrical first sealing rings 10 are fixedly inserted into the top of the diversion block 5, and the outer surfaces of the two partition plates 11 are respectively in contact with the inner walls of the two first sealing rings 10, and the two sides of the two partition plates 11 are in contact with the inner sides of the first diversion port 12. The two partition plates 11 are respectively located on both sides of the feed pipe 6.

[0022] To facilitate the installation and fixation of the device, mounting plates 4 are fixed to both sides of the diversion block 5, and one side of each of the two mounting plates 4 protrudes from the outside of both sides of the upper diversion plate 1. Each of the two mounting plates 4 has two symmetrical mounting holes at one end of the outside of both sides of the upper diversion plate 1.

[0023] Furthermore, in order to facilitate the disassembly and assembly of the two filter plates 19 for filtering the melt, all four mounting plates 18 are embedded in the bottom of the diversion plate 1, and the bottoms of the two threaded plug blocks 20 and the two mounting plates 18 are flush with the bottom of the diversion plate 1.

[0024] Furthermore, in order to better filter and divert the melt, gaps are formed between the tops of the two filter plates 19 and the tops of the two second diversion ports 15 on the upper diversion plate 1, and gaps are formed between the bottoms of the two filter plates 19 and the bottoms of the two second diversion ports 15 on the lower diversion plate 2.

[0025] In order to regulate the temperature inside the first diversion port 12 and avoid the problem of reduced fluidity caused by the decrease in melt temperature, a heating tube 14 is installed inside the diversion block 5, and one end of the heating tube 14 protrudes outside the diversion block 5. A gap is formed between the bottom of the fixing ring 7 and the top of the diversion block 5. An insertion sealing groove 16 is opened on the top of the lower diversion plate 2, and a second sealing ring 17 is fixedly connected to the bottom of the upper diversion plate 1, and the second sealing ring 17 is slidably inserted into the inside of the insertion sealing groove 16.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments.
