[0057] A use method of a static mixer for profile production line, comprising the following steps:

[0058] S1, in use, the right end cover 19 is connected with the external extruder, the profiled material melted by the extruder first enters the inside of the static mixer through the right interface 18, then the profiled material flows into the inside of the inner ring plate 62, and continues to flow to the left along the inner wall of the inner ring plate 62, until reaches the inside of the containing space on the right side of the inner cylinder 1;

[0059] S2, the profiled material in the right containing space is continuously gathered to the inner wall of the inner cylinder 1 under the limitation of the cone 14, and finally enters the vertical hole 16 on the right side of the inner cylinder 1 under the pressure of the extruder, and diffuses to the outside of the inner cylinder 1 in all directions under the conveying of the vertical hole 16, and flows into the buffer space 5;

[0060] S3, with the continuous inflow of the profiled material and the pressure of the extruder, the profiled material in the right buffer space 5 continuously gathers to the left along the outer wall of the inner cylinder 1 and the inner wall of the outer cylinder 2, and then enters the containing space on the left side of the inner cylinder 1 through the vertical hole 16 on the left side of the inner cylinder 1, and continues to flow to the left;

[0061] S4, when the profiled material enters the inside of the static mixer, the worker injects cooling liquid into the first pipeline 73 on the left side of the shell 72, the cooling liquid flows to the right along the groove 71, and then flows out through the second pipeline 74 on the right side of the shell 72, so as to perform temperature regulation on the static mixer once;

[0062] S5, during the temperature regulation once, the worker can also inject cooling liquid into the second pipeline 74 on the left side of the inner cylinder 1, the cooling liquid enters the channel 11, and flows to the right along the vertical hole 13, and then flows out through the second pipeline 74 on the right side of the inner cylinder 1, so as to perform temperature regulation twice on the static mixer;

[0063] S6. The profile material flowing to the left will first reach the heater 20 and be reheated. After maintaining its own temperature, it will continue to flow to the left into the mold body 21 and finally be extruded, thus completing the mixed production of the profile material.

[0064] Implementation method: (see attached) Figure 1 For example, when this utility model is in use, the end cap 19 located on the right side of the inner cylinder 1 is connected to the external extruder. The first pipe 73 located on the left side of the shell 72 and the second pipe 74 located on the left side of the inner cylinder 1 are liquid inlet pipes for injecting coolant, such as water or cooling oil. The first pipe 73 located on the right side of the shell 72 and the second pipe 74 located on the right side of the inner cylinder 1 are liquid outlet pipes for the coolant to flow out. This makes the flow direction of the coolant opposite to the flow of the profile material, thus improving the cooling effect of the coolant.

[0065] Specifically, the profile material melted by the extruder first enters the static mixer through the right-side interface 18. Then, the profile material flows into the inner ring plate 62 and continues to flow to the left along the inner wall of the inner ring plate 62 until it reaches the receiving space on the right side of the inner cylinder 1. During the flow, due to the guidance of the third arc surface 67, the profile material will flow smoothly to the left along the third arc surface 67, thus smoothly transitioning into the inner cylinder 1. There will be no backflow at the connection between the inner ring plate 62 and the inner cylinder 1, thus avoiding leakage at the connection between the inner ring plate 62 and the inner cylinder 1.

[0066] Furthermore, the profiled material inside the right-side receiving space, limited by the cone 14, will continuously accumulate towards the inner wall of the inner cylinder 1. Finally, under the pressure of the extruder, it enters the vertical hole 16 on the right side of the inner cylinder 1. Conveyed by the vertical hole 16, it diffuses outwards in all directions, flows into the buffer space 5, and accumulates to the left along the outer wall of the inner cylinder 1 and the inner wall of the outer cylinder 2. It then re-enters the inner cylinder 1 through the vertical hole 16 on the left side. At this point, the profiled material is located inside the left-side receiving space. Furthermore, when the profiled material transitions into and flows out of the buffer space 5, due to the cooperation of the first stop groove 3 and the second stop groove 65, the outer ring plate 63 can be inserted into the buffer space 5 in a manner that is tightly attached to the inner wall of the outer cylinder 2 and the outer wall of the inner cylinder 1. At this time, the outer ring plate 63 is set to an interference fit with the outer cylinder 2 and the inner cylinder 1, which has a high sealing performance and initially prevents the profiled material from flowing out and leaking through the connection between the outer ring plate 63 and the outer cylinder 2 and the inner cylinder 1, that is, the right or left side of the buffer space 5.

[0067] At the same time, the profiled material in the right side of the inner cylinder 1 will flow left along the second arc surface 66 when it enters the buffer space 5, and under the guidance of the second arc surface 66, the profiled material will always have a tendency to flow left, which can smoothly transition to the left side of the buffer space 5, thereby avoiding the profiled material leaking through the right side of the buffer space 5 again;

[0068] Similarly, when the profiled material enters the inner cylinder 1 again on the left side of the suture gap, the second arc surface 66 on the left side will guide the profiled material at the left end of the buffer space 5, so that the profiled material at this position has a flow tendency of turning down along the second arc surface 66, thereby avoiding the profiled material leaking through the left side of the buffer space 5 during flow transition, and accurately flowing back to the inner cylinder 1 through the vertical hole 16 on the left side;

[0069] The first arc surface 4 in the buffer space 5 not only guides the profiled material to flow from right to left, but also has a design of gradually moving away from the middle by the two ends, which not only reduces the pressure of the profiled material during flow, but also allows the buffer space 5 to accommodate more profiled material, thereby improving the production efficiency of the profiled material;

[0070] The mating surface of the first stop groove 3 and the second stop groove 65 is embedded with a sealing element 64, i.e. an O-shaped sealing ring, which greatly improves the sealing performance of the connection between the outer ring plate 63 and the outer cylinder 2. That is, under the action of the first stop groove 3, the second stop groove 65, the second arc surface 66, the third arc surface 67, and the sealing element 64, the sealing between the flange 61 and the inner cylinder 1 and the outer cylinder 2 becomes radial sealing, which can effectively guide the flow path of the profiled material in a molten state and avoid the leakage of the profiled material, thereby greatly improving the sealing performance of the static mixer;

[0071] Further, due to the continuous pressure of the extruder and the continuous influx of the profiled material, the profiled material reaching the left side of the inner cylinder 1 will continue to flow left into the heater 20, be heated again, and then flow into the die body 21 at a high temperature, and be further extruded, thereby completing the mixing production of the profiled material;

[0072] When the profiled material enters the static mixer, the staff injects cooling liquid into the first pipeline 73 on the left side of the shell 72, which flows right along the channel 71 and then flows out through the second pipeline 74 on the right side of the shell 72, thereby performing a temperature regulation on the static mixer;

[0073] During the temperature regulation process, the staff can also inject cooling liquid into the second pipeline 74 on the left side of the inner cylinder 1, which enters the channel 11 and flows along the horizontal hole 13 to the right, and then flows out through the second pipeline 74 on the right side of the inner cylinder 1, so as to regulate the temperature of the static mixer again;

[0074] Meanwhile, a temperature sensor 17 is additionally arranged on the left side of the inner cylinder 1, which is a WRENK-291 type, and can test the temperature of the inner cylinder 1, i.e. the temperature inside the static mixer, so as to determine whether to simultaneously perform two cooling processes, so as to ensure that the temperature inside the static mixer is appropriate, and the two different temperature regulation processes can quickly cool the temperature inside the static mixer, and the temperature regulation speed is fast, the method is various, the stability is high, and it is beneficial to the use of the static mixer.

[0075] The embodiment specifically solves the problem that the current static mixer adopts end face sealing, the sealing performance is not high, the profiled material is easy to leak, and the existing static mixer only has one temperature regulation medium channel 11 during use, the temperature regulation speed is slow, and the use is affected.

[0076] The above only describes some exemplary embodiments of the utility model in a descriptive manner, without doubt, for ordinary skilled in the art, under the condition of not deviating from the spirit and scope of the utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the protection scope of the utility model claims.
