Description

TECHNICAL FIELD

[0001] The present application relates to a mixing device, in particular to an X rheological mixing device and its application in injection molding machines and extruders. BACKGROUND

[0002] Nowadays, the types of plastics in the injection molding industry are constantly updated, the performance is constantly improved, and the plastic additives are constantly changing and increasing, making it more and more difficult to improve product quality by relying entirely on injection molding process or screw design. One of the most difficult problems to solve is uneven mixing of products and poor plasticization. Moreover, the overall plastic raw material price is rising, and the proportion of many enterprises using recycled materials is increasing. However, foreign objects such as iron filings inevitably enter the recycled materials during use, causing blockage in the hot runner of the mold during production, causing unnecessary losses and a large amount of downtime for maintenance and waiting time for customers. The methods used to solve the above two problems in the market are to increase the device for filtering iron filings and to increase the mixing effect device. Both can only solve a single technical problem, causing great distress to injection molding machine manufacturers and end users.

[0003] To solve the above two technical problems, the applicant has previously developed a filtering mixing nozzle disclosed in patent CN110091469A, which includes a rheological valve core head and at least one prismatic rheological valve core assembled together. By the double flow change of the prismatic rheological valve core and the rheological valve core head, the melted plastic can be guided, cross-fused, and compressed to guide the flow in the through hole of the sub-nozzle and the flange connector. The continuous flow guidance not only compensates for the incomplete fusion and color unevenness of the plastic in the screw pipe.

[0004] However, in actual application, it is found that the filtering mixing nozzle disclosed in patent CN110091469A has another problem after solving the above two problems, that is, the valve core in the nozzle is prone to carbon deposition and produces some black spots, which inevitably increases the product failure rate. The solution of coating a coating on the surface of the valve core cannot effectively improve the product pass rate.

[0005] Therefore, how to solve the problem of carbon deposition and black spot generation in the valve core of the existing mixing device after long-term use has become another big technical problem for technicians in the field to solve. SUMMARY

[0016] Further preferably, in the X rheological mixer, the quadrilateral large hole is a shape of a harp, or a rhombus, or a square.

[0017] Further, in the X rheological mixer, the side end face of the circular ring type end portion is a ring type inclined surface.

[0018] The second aspect of the present application provides an X rheological mixer, which is an injection nozzle mixer of an injection machine, comprising a sub-nozzle, a flange connecting body and an integrated X rheological valve core as described above, wherein:

[0019] The integrated X rheological valve core is arranged in the through hole between the sub-nozzle and the flange connecting body, and the side end face of the circular ring type end portion is in close contact with the inner hole wall of the sub-nozzle.

[0022] The integrated X rheological mixing valve core is arranged in the through hole of the adapter die, and the annular end surface of the annular end portion is in close contact with the inner hole wall of the adapter die.

[0023] Further, on the X rheological mixer, the inner hole wall of the adapter die is provided with an adapter inclined surface, which is in inclined surface contact with the annular inclined surface of the annular end surface.

[0072] Please continue to refer to Figure 5 and Figure 6 The working process of the extruder discharge mixing adapter device provided by the embodiment is as follows:

[0073] Before the extrusion molding starts, the extruder machine advances to contact and press the front end of the adapter die head 400 with the glue inlet of the mold. The plastic is forced to melt and flow into the inner hole of the adapter die head 400 under the pushing of the screw rod. The melted plastic flows into the quadrilateral cavity through the small holes 104 on the V-shaped rheological end part 103 at the same time;

[0074] Then the flow direction of the plastic is branched into multiple paths through the X-shaped valve core rheological part 102. The plastic is extruded into the V-shaped cavity of the integral X-shaped rheological mixing valve core 100 through the several small holes 104 on the inclined surface of the X-shaped valve core rheological part 102, and then enters the large hole surrounded in front through the X-shaped valve core rheological part 102.

[0075] After multiple cross-flow fusion, the plastic is finally compressed into the triangular cavity between the X-shaped valve core rheological part 102 and the circular ring-shaped end part 101, and then flows into the mold through the adapter die head 400.

[0076] Comparative Example 1

[0077] The filter mixing nozzle disclosed in the patent CN110091469A of the company is used as a comparative example for injection molding production. The injection molding process is as follows: before starting injection molding, the injection machine moves forward to the front of the nozzle, the R spherical surface at the front end of the sub nozzle is in contact with and pressed against the R spherical surface of the mold glue inlet, and the melted plastic is forced to flow into the inner hole of the prismatic rheological valve core under the push of the screw rod, and then into the inner cavity of the prismatic rheological valve core. The prismatic rheological valve core branches the flow direction of the plastic into two paths, the plastic is extruded into the middle cavity of the prismatic rheological valve core through several small holes on the prismatic shape of the prismatic rheological valve core, and then enters the large hole in front of it after crossing. After several times of crossing and merging, the plastic is finally compressed into the cavity between the rheological valve core head and the sub nozzle, and then injected into the mold.

[0078] Performance test:

[0079] The integrated injection machine injection nozzle mixer of Example 2 of the present application is used as the test group, and the split filter mixing nozzle of Comparative Example 1 is used as the control group. The overall size and structure of the mixing nozzles used in the two groups are the same. The processing production cycle, service life under the same plastic raw material and the same process conditions, disassembly and cleaning time, failure rate and maintenance cycle are tested respectively. The test results are shown in Table 1 below.

[0080] Table 1 Performance test results of integrated nozzle mixer and split mixing nozzle

[0081]

[0082] As can be seen from the test data in Table 1 above, compared with the existing split filter mixing nozzle, the X rheological mixer of the present application greatly shortens the processing cycle and reduces the production cost. The average service life is extended by more than 2 times, the disassembly and cleaning time of the equipment is reduced from 3 hours to 1 hour, the occurrence of faults is avoided, and the maintenance cycle is extended from half a year to one year.

[0083] In addition, the X rheological mixer completely solves the problem of misalignment between the contact surfaces of multiple valve cores and the problem of black spots, black lines and yellow lines caused by hidden glue, and also solves the problem of deformation and cracking of split valve cores. The use effect is better: only one integrated filter mixing valve core is used, which can be installed and disassembled at will, is convenient and fast, saves time and effort, is convenient for maintenance and replacement, improves the processing efficiency, and reduces the manufacturing cost.

[0084] The above detailed description of the application is only as an example, and the application is not limited to the above described specific embodiments. Any equivalent modifications and substitutions made by those skilled in the art to the application are also within the scope of the application. Therefore, equivalent transformations and modifications made without departing from the spirit and scope of the application should be covered within the scope of the application.
