Description

Technical Field

[0001] The present application relates to the technical field of polymer material processing, and in particular to an atomizing mechanism for a mixing device, a mixing device and a mixing method. Background Art

[0002] With the continuous progress and innovation of technology in the field of polymer materials, polytetrafluoroethylene (PTFE), as a special material with excellent performance, has gradually emerged and occupied a pivotal position. PTFE shines in many high-end application fields with its non-toxic, odorless, excellent sealing performance, high and low temperature resistance, and chemical corrosion resistance; especially in the field of insulation materials for special wires and cables, PTFE has become the preferred material for extreme environmental conditions such as medical equipment, high-frequency communications, aerospace, national defense and military with its ultra-high insulation performance, reliability, and extremely low dielectric loss, meeting the stringent requirements of these fields for material performance. However, in terms of the processing technology of PTFE dispersion resin, due to the large molecular weight, high melting point, and extremely high viscosity of PTFE dispersion resin in the molten state, the traditional high-temperature melt extrusion process is no longer applicable.

[0003] In the related technology, PTFE dispersion resin is often processed and produced by paste extrusion process in a non-molten state to cope with the problem of difficult processing of PTFE dispersion resin. The core of this paste extrusion process is that it requires the PTFE dispersion resin and the auxiliary oil to be pre-mixed manually in a strictly controlled temperature environment below 19°C. Subsequently, the mixture will be sent to the mixer for non-interventional deep mixing to ensure the initial combination between the resin and the auxiliary oil. Next, after aging treatment, compaction molding, extrusion operation, calendering flattening, degreasing treatment, and the final stretching process, high-quality raw tape products are produced.

[0004] However, although the paste extrusion process has solved the processing difficulties of PTFE dispersed resin to a certain extent, it still exposes a series of technical problems in its actual application. First, PTFE resin is very prone to fiberization during the mixing stage, which is mainly due to the difficulty in accurately controlling the shear force during the manual premixing process; this fiberization not only reduces the efficiency of mixing, but may also cause fluctuations in the performance of the final product. Secondly, the mixing uniformity between the auxiliary oil and the PTFE resin becomes a technical problem. Due to the uncertainty in the mixing process, quality problems such as uneven dryness and wetness and local agglomeration are likely to occur. These problems will directly affect subsequent processing and seriously threaten the stability and reliability of product quality. Summary of the invention

[0005] Based on this, it is necessary to provide an atomizing mechanism, a mixing device and a mixing method to address the above problems, so as to effectively mix the PTFE dispersed resin particles and the auxiliary oil evenly and improve the production efficiency of the raw tape.

[0012] In one embodiment, it also includes an atomization control mechanism, which is electrically connected to the atomization nozzle and is used to control the opening and closing of the atomization nozzle and the size of the atomization amount.

[0013] On the other hand, the present application also relates to a mixing device, comprising the above-mentioned atomizing mechanism, and further comprising:

[0014] The constant temperature chamber is configured as a sealed chamber to maintain a constant internal temperature;

[0015] A mixing barrel is placed in the constant temperature warehouse, comprising a barrel body, a barrel cover connected to the barrel body, and bearings arranged on both sides of the barrel body in a horizontal direction, wherein at least one side of the bearing is provided with a through hole for an oil inlet pipeline to pass through; and

[0016] At least one driving roller is against the mixing barrel and is configured to drive the mixing barrel to rotate by rotating the driving roller.

[0017] In one of the embodiments, the constant temperature bin includes a constant temperature bin body, a constant temperature bin door and a bin door handle. The constant temperature bin door is opened through the bin door handle, and the mixing barrel is pulled out or pushed into the constant temperature bin body through the barrel handle.

[0018] In one of the embodiments, the constant temperature bin and the mixing barrel are both made of transparent materials to observe the mixing process and mixing uniformity.

[0019] On the other hand, the present application also relates to a mixing method, which uses the above-mentioned mixing device to mix PTFE dispersed resin, comprising the following steps:

[0020] Open the thermostatic chamber door and pull out the mixing barrel through the barrel handle;

[0021] Close the through hole of the bearing at the bottom of the mixing barrel, and add the weighed PTFE dispersion resin into the mixing barrel;

[0022] Place the mixing barrel horizontally and shake it slightly to make the PTFE dispersed resin flat;

[0023] Open the through hole of the bearing at the bottom of the mixing barrel, insert the mixing barrel into the horizontal oil inlet pipeline, and slide the mixing barrel horizontally into the constant temperature chamber along the length direction of the driving roller;

[0024] Push the mixing barrel completely into the constant temperature bin and close the constant temperature bin door;

[0025] Adjust the temperature of the constant temperature chamber, and after the temperature stabilizes, add the weighed additive oil through the atomization mechanism;

[0026] During the process of adding the auxiliary oil, start the driving roller to drive the mixing barrel to rotate, so that the auxiliary oil and the PTFE dispersed resin are evenly mixed until all the auxiliary oil is added to the PTFE dispersed resin;

[0027] After all the auxiliary oil is added, the heat preservation and aging process is carried out.

[0028] In one embodiment, after the mixing barrel is completely pushed into the constant temperature chamber, the temperature of the constant temperature chamber is adjusted to below 19° C. until the temperature stabilizes.

[0030] In one embodiment, the process of adding auxiliary oil by the atomizing mechanism is: the auxiliary oil is added to the mixing barrel in an atomized form through the atomizing nozzle, and the auxiliary oil sprayed by the atomizing nozzle fully covers the mixing area directly below the oil inlet pipe to ensure sufficient mixing of the auxiliary oil and the PTFE dispersed resin.

[0054] Combination Figure 1-Figure 2 As shown, Figure 1 A schematic diagram of the structure of a mixing device 1000 in an embodiment of the present application in a front view state is shown; Figure 2 It shows Figure 1 Side view of.

[0055] An embodiment of the present application provides an atomization mechanism 200 , including an oil filling port 210 , an oil storage tank 220 , an oil inlet pipeline 230 and an atomization nozzle 240 .

[0056] In some embodiments, the oil filling port 210 is used to add auxiliary oil; specifically, the oil filling port 210 is designed above the oil storage tank 220 to facilitate the injection of auxiliary oil.

[0057] In some embodiments, the oil storage tank 220 is connected to the oil filling port 210 for storing the added auxiliary oil to prevent the auxiliary oil from overflowing from the oil filling port 210; specifically, the internal cavity of the oil storage tank 220 has sufficient capacity to ensure a continuous supply of auxiliary oil during the mixing process.

[0058] In some embodiments, the oil inlet pipe 230 connects the oil storage tank 220 and the atomizing nozzle 240, and the auxiliary oil flows through the oil storage tank 220 to the position of the atomizing nozzle 240 after being injected into the oil filling port 210. Specifically, the oil inlet pipe 230 includes a first pipe portion connected to the oil storage tank 220 and a second pipe portion connected to the atomizing nozzle 240. When the first pipe portion turns to transition to the second pipe portion, a 90° arc structure is adopted to ensure that the auxiliary oil can flow smoothly from the first pipe portion to the second pipe portion, avoiding oil accumulation or blockage at the turning point; the arc structure not only optimizes the flow path of the auxiliary oil and reduces the flow resistance, but also ensures that the auxiliary oil can be evenly sprayed through the atomizing nozzle 240, which helps to improve the atomization effect of the auxiliary oil and make it evenly mixed with the PTFE dispersed resin.

[0059] In some embodiments, the atomizing nozzle 240 is disposed at the bottom of the oil inlet pipe 230 and above the mixing area inside the mixing barrel 300, and is used to atomize the auxiliary oil. The auxiliary oil sprayed by the atomizing nozzle 240 fully covers the mixing area directly below the horizontal oil inlet pipe 230. The atomizing nozzle 240 continuously sprays the auxiliary oil in the form of atomization, realizing dynamic mixing with the PTFE dispersed resin in the mixing barrel 300, greatly increasing the contact area between the auxiliary oil and the PTFE dispersed resin, and promoting their full mixing; in actual work, the number of atomizing nozzles 240 can be adjusted according to the size of the mixing barrel 300 and the mixing requirements to achieve the best mixing effect.

[0060] In the atomization mechanism 200 of the present application, the oil storage tank 220 is tightly connected to the oil filling port 210, ensuring the effective storage of the auxiliary oil and preventing the auxiliary oil from overflowing from the oil filling port 210. After the auxiliary oil is added at the oil filling port 210, it can be stably stored in the oil storage tank 220, avoiding contamination or volatilization caused by direct exposure of the auxiliary oil to the environment, thereby ensuring the purity and stability of the auxiliary oil.

[0061] Please combine again Figure 3-Figure 4 As shown, Figure 3 A schematic structural diagram of a mixing barrel 300 in an embodiment of the present application is shown; Figure 4 It shows a schematic structural diagram of the mixing device 1000 in one embodiment of the present application after the mixing barrel 300 is pulled out.

[0062] An embodiment of the present application provides a mixing device 1000 , which includes the above-mentioned atomization mechanism 200 , and further includes a constant temperature chamber 100 , a mixing barrel 300 , a driving roller 400 and a control mechanism 500 .

[0063] In some embodiments, the constant temperature chamber 100 is configured as a sealed cavity for maintaining a constant internal temperature. The constant temperature chamber 100 includes a chamber body, a constant temperature chamber door 110, and a chamber door handle 120. The constant temperature chamber door 110 is opened through the chamber door handle 120, and the mixing barrel 300 can be pulled out or pushed into the constant temperature chamber 100 through the barrel handle 310; the constant temperature chamber 100 provides a stable temperature environment for the mixing process, which helps to ensure that the physical and chemical properties of the auxiliary oil and the PTFE dispersed resin remain stable during the mixing process. At the same time, the sealing of the constant temperature chamber 100 also prevents external factors from interfering with the mixing process.

[0064] Furthermore, the material of the constant temperature chamber 100 is selected to be transparent so as to observe the mixing process and judge the uniformity of the mixing.

[0065] In some embodiments, the mixing barrel 300 is disposed in the constant temperature warehouse 100, and the mixing barrel 300 includes a barrel body, a barrel cover 320, and a top bearing 330 and a bottom bearing 340 respectively disposed on both sides of the barrel body in the horizontal direction;

[0066] Furthermore, the transverse oil inlet pipe 230 in the atomizing mechanism 200 sequentially passes through the top bearing 330 and the bottom bearing 340 located on both sides of the barrel in the horizontal direction and is coaxially arranged with the mixing barrel 300; the matching structure of the mixing barrel 300, the top bearing 330 and the bottom bearing 340 enables the mixing barrel 300 to rotate smoothly in the constant temperature chamber 100 when driven by the driving roller 400, and the arrangement of the top bearing 330 and the bottom bearing 340 ensures that the transverse oil inlet pipe 230 of the mixing barrel 300 is not affected during the rotation process, and the top bearing 330 and the bottom bearing 340 can also ensure the sealing inside the mixing barrel 300, the stability and smoothness of the rotation of the mixing barrel 300, and the synergistic effect of the mixing barrel 300, the top bearing 330 and the bottom bearing 340 help to fully mix the auxiliary oil and the PTFE dispersed resin in the mixing barrel 300;

[0067] When the barrel cover 320 is tightened, the interior of the mixing barrel 300 can be kept in a sealed state; when it is unscrewed, PTFE dispersed resin powder can be easily added;

[0068] A sealing cover is provided on the bottom bearing 340, and the bearing through hole is opened or closed by the sealing cover. At the same time, a sealing ring is provided on the inner wall of the bottom bearing 340, and the sealing ring fits tightly with the horizontal oil inlet pipe 230 to keep the interior of the mixing barrel 300 in a closed state to prevent the auxiliary oil from evaporating out of the mixing barrel 300.

[0069] Furthermore, the material of the mixing barrel 300 is transparent, which is convenient for observing the mixing process and judging the uniformity of the mixing.

[0070] In some embodiments, the driving roller 400 abuts against the mixing barrel 300 to drive the mixing barrel 300 to rotate; the rotation of the driving roller 400 generates friction between the driving roller 400 and the mixing barrel 300, thereby driving the mixing barrel 300 to rotate, thereby achieving dynamic mixing of the auxiliary oil and the PTFE dispersed resin. This mixing method not only improves the mixing efficiency, but also helps to ensure the uniformity of the mixing;

[0071] Further, the driving roller 400 at least includes a front driving roller 410 and a rear driving roller 420, which are arranged at both sides of the bottom of the mixing barrel 300 and abut against the mixing barrel 300, and the front driving roller 410 and the rear driving roller 420 rotate synchronously and generate friction with the mixing barrel 300, and drive the mixing barrel 300 to rotate through the friction force;

[0072] Furthermore, the material of the driving roller 400 can be selected from at least one of natural rubber, EPDM, chloroprene rubber, silicone rubber, and fluororubber to increase the friction between the driving roller 400 and the mixing barrel 300, thereby effectively driving the mixing barrel 300 to rotate.

[0073] In some embodiments, the control mechanism 500 includes a drive control mechanism 510 , an atomization control mechanism 520 , and a temperature control mechanism 530 .

[0074] The drive control mechanism 510 includes a drive switch 511 and a speed regulator 512, which are used to control the opening and closing of the drive roller 400 and the speed regulation;

[0075] The atomization control mechanism 520 includes an atomization switch 521 and an atomization amount regulator 522, which are used to control the opening and closing of the atomization nozzle 240 and the size of the atomization amount.

[0076] The temperature control mechanism 530 includes a temperature control switch 531 and a temperature regulator 532, which are used to adjust the temperature of the constant temperature chamber 100. Furthermore, the adjustable temperature range of the temperature regulator 532 includes at least 15-60°C.

[0077] In some embodiments, a support frame 600 is further included, and the support frame 600 is used to provide support force to the bottom of the entire mixing device 1000 .

[0078] In addition, an embodiment of the present application further provides a mixing method, which uses the above-mentioned mixing device 1000 to mix PTFE dispersed resin, including a preparation stage, a mixing stage, a maturation stage and an end stage.

[0080] Open the thermostatic chamber door 110 and pull out the mixing barrel 300 through the barrel handle 310;

[0081] Close the through hole of the bearing 340 at the bottom of the mixing barrel 300, and add the weighed PTFE dispersion resin into the mixing barrel 300. The added amount should be ≤ 1 / 2 of the volume of the mixing barrel 300 to reserve enough space for the auxiliary oil and the PTFE dispersion resin to mix;

[0082] Place the mixing barrel 300 horizontally and shake it slightly to make the PTFE dispersed resin flat;

[0083] The through hole of the bearing 340 at the bottom of the mixing barrel 300 is opened, and the mixing barrel 300 is inserted into the transverse oil inlet pipe 230, and the mixing barrel 300 is horizontally slid into the constant temperature chamber 100 along the length direction of the driving roller 400;

[0084] Push the mixing barrel 300 completely into the constant temperature chamber 100 and close the constant temperature chamber door 110 .

[0085] Furthermore, the specific steps of the mixing stage are as follows:

[0086] Adjust the temperature control mechanism 530 to adjust the temperature of the constant temperature chamber 100 to below 19° C. and wait for the temperature to stabilize to ensure that the mixing process is carried out in a low temperature environment, which helps prevent the PTFE dispersed resin from becoming fibrillated;

[0087] Add weighed auxiliary oil from the oil filling port 210, and fill the oil storage tank 220 and the oil inlet pipe 230 with the auxiliary oil;

[0088] Turn on the atomization switch 521, and adjust the atomization amount through the atomization amount regulator 522 to ensure that the auxiliary oil is sprayed with an appropriate atomization amount;

[0089] Turn on the driving switch 511, adjust the speed of the driving roller 400 to 90-110 rpm through the speed regulator 512, and start rotating the mixing barrel 300;

[0090] During the process of adding the auxiliary oil, the mixing barrel 300 is continuously driven to rotate so that the auxiliary oil and the PTFE dispersion resin are evenly mixed until all the auxiliary oil is added into the PTFE dispersion resin.

[0091] Further, the specific steps of the maturation stage are as follows:

[0092] After all the additive oil is added, the atomizing switch 521 and the driving switch 511 are turned off;

[0093] Adjust the temperature control mechanism 530 to adjust the temperature of the constant temperature chamber 100 to a range of 45-55° C. to perform a heat preservation and aging process for 24 hours;

[0094] The aging stage helps to further promote the fusion and stabilization of the additive oil and PTFE dispersed resin, thereby improving the performance and quality of the final product.

[0095] Furthermore, the specific steps of the ending phase are as follows:

[0096] After the aging process is completed, the temperature control switch 531 is turned off.

[0097] Open the thermostatic chamber door 110 and pull out the mixing barrel 300 horizontally through the barrel handle 310 .

[0098] The through hole of the bearing 340 at the bottom of the mixing barrel 300 is closed, and the mixing barrel 300 is placed vertically.

[0099] Unscrew the barrel cover 320, pour out the mixed material, and enter the next production process.

[0100] The present application, through the above-mentioned mixing method, utilizes the synergistic effect between the atomizing mechanism 200, the mixing barrel 300, the driving roller 400 and the control mechanism 500, which can effectively solve the problems of fiberization and uneven mixing in the mixing process of PTFE dispersed resin and auxiliary oil. The temperature can be adjusted in the constant temperature chamber 100 in the present application, so as to take into account the mixing and heat preservation and aging functions, and improve the production efficiency and product quality stability of the raw tape; in addition, the auxiliary oil of the present application is sprayed out through the atomizing nozzle 240 of the atomizing mechanism 200, and is continuously sprayed out in the form of atomization, and is added to the PTFE dispersed resin powder that is dynamically moving in the mixing barrel 300, so that the two can be fully and evenly mixed, which reduces the difficulty of subsequent processing and greatly improves the stability of the raw tape product quality.
