Description

Technical Field

[0002] Currently in the industrial field, anti-aging agents are generally used to improve the durability of rubber. These anti-aging agents can be classified into antioxidants, anti-ozone agents, anti-fatigue agents, anti-ultraviolet agents, etc. according to their functions. By mixing natural rubber with synthetic materials such as styrene-butadiene rubber or cis-1,4-polybutadiene rubber, the aging resistance of rubber can be significantly improved, and at the same time, the plasticity and dimensional stability of the rubber compound can be improved, which not only helps to reduce production costs.

[0003] When the existing rubber composite materials are mixed and kneaded, most of the temperatures are controlled at 80 - 100°C. In order to avoid the premature reaction of vulcanizing agents and accelerators, the upper limit temperature generally does not exceed 110 - 115°C. However, when the rubber composite materials are kneaded, since the melting temperatures of the materials to be compounded are different, such as 140 - 170°C for NR, 130 - 150°C for SBR, 120 - 140°C for BR, and not higher than 130°C for EPDM, when the existing kneading machines set the temperature to melt and knead different materials, if the temperature control is improper, problems such as poor dispersion of the composite materials, poor compatibility, or uneven density and abnormal plasticity are likely to occur.

[0004] Therefore, in view of the above technical problems, a preparation device for a high-strength and aging-resistant polymer rubber composite material is proposed. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] First, the composite material to be processed is preheated at 50-70 °C by the low-temperature mixer to soften it. Then, the softened composite material is extruded into a long strip by the mixing screw and the extrusion frame. When preheating and mixing at 50-70 °C, corresponding additives are added thereto, so that the additives are fused with the composite material. This is the first-stage mixing. Subsequently, the second-stage high-temperature mixing is carried out on it. Through the composite step of layered temperature, the oxidation and thermal aging of rubber are inhibited at low temperature, the molecular chain integrity of polar rubber is protected, and the problem of scorching is avoided. At high temperature, the viscosity of the rubber compound is reduced, the fluidity is enhanced, which is convenient for subsequent processing such as calendering and extrusion. Furthermore, the effect of compounding various different materials in the composite rubber is improved, and the quality of the composite rubber production is improved.

[0020] Second, through the structural cooperation design of the positioning and cutting component and the winding component, the rubber that forms a long strip after low-temperature processing and kneading is wound. When heating and stretching the rubber, the molecular chains elongate along the stretching direction and are partially untangled, forming an oriented arrangement structure, which improves the ductility of the rubber compound. The number of cross-linking points increases after winding, and the binding between molecular chains becomes tighter, which can delay the crack propagation and improve the durability of rubber products. The spiral structure of the twist coil can fill the voids, reduce the bubbles and impurity residues at the fusion interface, improve the overall density, and facilitate the mixing of the low-temperature kneaded rubber through stretching and winding, improving the mixing effect of its internal materials, reducing the uneven mixing caused by lump extrusion, and reducing the quality problems in the compounding of composite rubber.

Detailed implementation mode

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0033] Example 1, as Figures 1 - 10 shown, it includes an operating body 1. To facilitate the low-temperature kneading of composite rubber, a low-temperature kneader 2 is fixedly connected to the top end of one end of the operating body 1. A plurality of kneading screws 3 are arranged inside the low-temperature kneader 2. To facilitate the extrusion of the low-temperature kneaded composite rubber into strips, an extrusion frame 4 is fixedly connected to one end of the low-temperature kneader 2. An extrusion rod 5 is arranged inside the extrusion frame 4, and one end of the extrusion rod 5 is in contact with the kneading screw 3;

[0034] A positioning and cutting assembly is arranged at the position of the extrusion frame 4 far from the kneading screw 3, and the positioning and cutting assembly is used in cooperation with the kneading screw 3 and the extrusion frame 4;

[0035] A winding assembly is arranged at the position of the positioning and cutting assembly far from the extrusion frame 4, and the winding assembly is used in cooperation with the positioning and cutting assembly and the extrusion frame 4.

[0036] During operation, the composite material to be processed is preheated to 50 - 70°C by the low-temperature mixer 2 to soften it. Then, the softened composite material is extruded into a long strip by the mixing screw 3 and the extrusion frame 4. When preheating and mixing at 50 - 70°C, corresponding additives are added to it, so that the additives and the composite material are fused with each other. This is the first-stage mixing. The low temperature inhibits rubber oxidation and thermal aging, protects the molecular chain integrity of polar rubber, and avoids the problem of scorching. The low-temperature mixing ensures the full dispersion of small-particle fillers such as silica and anti-aging agents by extending the shear time, such as the open mill temperature of cis-butadiene rubber being 40 - 50°C, thereby improving the mixing effect of the composite rubber.

[0037] Example 2, as Figures 3 - 7 shown, the positioning and cutting assembly includes a moving air column 6, a fixed seat 7, a first positioning circular seat 8, and a first positioning cutter 9. The top end of the extrusion frame 4 away from the mixing screw 3 is fixedly connected to the moving air column 6. The end of the moving air column 6 close to the extrusion frame 4 is fixedly connected to the fixed seat 7. To facilitate the positioning of the extruded composite rubber strip, the bottom end of the fixed seat 7 and the end away from the extrusion frame 4 are fixedly connected to the first positioning circular seat 8, and multiple groups of first positioning cutters 9 are arranged inside the first positioning circular seat 8.

[0038] The positioning and cutting assembly further includes a second positioning circular seat 10, a hollow guide rod 11, and an annular rack 12. To facilitate the cutting of the rubber strip after it is wound and formed, the bottom end of the fixed seat 7 and the end close to the extrusion frame 4 are rotatably connected to the second positioning circular seat 10. The hollow guide rod 11 is fixedly connected to the inner side of the second positioning circular seat 10 at a position corresponding to the extrusion rod 5. To facilitate driving the rotation of the second positioning circular seat 10, one side of the top of the second positioning circular seat 10 is fixedly connected to the annular rack 12.

[0039] The positioning and cutting assembly further includes a fixing plate 13, a first servo motor 14, and a first transmission gear 15. The fixing plate 13 is fixedly connected to one side of the fixed seat 7 close to the annular rack 12. The end of the fixing plate 13 away from the extrusion frame 4 is fixedly connected to the first servo motor 14. The first transmission gear 15 is rotatably connected to the end of the fixing plate 13 close to the extrusion frame 4. The output end of the first servo motor 14 is fixedly connected to the first transmission gear 15, and the annular rack 12 is meshed with the first transmission gear 15, thereby facilitating driving the rotation of the first transmission gear 15 by the first servo motor 14.

[0040] To facilitate pulling out the extruded composite rubber strip for subsequent winding, the winding assembly includes a moving rod 16, a cylinder moving seat 17, a fixed ring frame 18, and a winding ring seat 19. A moving rod 16 is fixedly connected to the inner side of the first positioning circular seat 8. A cylinder moving seat 17 is slidably connected to the outer sides of the moving air column 6 and the moving rod 16. A fixed ring frame 18 is fixedly connected to the bottom end of the cylinder moving seat 17. A winding ring seat 19 is rotatably connected to the inner side of the fixed ring frame 18, thereby facilitating driving the winding ring seat 19 to slide on the moving air column 6 through the moving rod 16 and the cylinder moving seat 17, and making it convenient to drive the composite rubber strip to be pulled out from the extrusion frame 4.

[0041] The winding assembly further includes a winding frame 20, a second servo motor 21, a second transmission gear 22, and a transmission ring gear 23. To facilitate the rotation of the winding ring seat 19 within the fixed ring frame 18, a winding frame 20 is fixedly connected to the end of the cylinder moving seat 17 away from the extrusion frame 4. A second servo motor 21 is fixedly connected to the bottom of the winding frame 20 and at the end away from the extrusion frame 4. A second transmission gear 22 is rotatably connected to the bottom of the winding frame 20 and at the end close to the extrusion frame 4. The output end of the second servo motor 21 is fixedly connected to the second transmission gear 22. A transmission ring gear 23 is fixedly connected to the end of the winding ring seat 19 away from the extrusion frame 4. The second transmission gear 22 is meshed with the transmission ring gear 23, thereby facilitating driving the second transmission gear 22 and the winding ring seat 19 to rotate through the second servo motor 21.

[0042] The winding assembly further includes a third positioning circular seat 24, a second positioning cutter 25, a limiting disc 26, a guiding pin column 27, and an adjusting screw 28. To facilitate fixing the composite rubber strip extruded by the extrusion frame 4 and the extrusion rod 5, a third positioning circular seat 24 is fixedly connected to the inner side of the winding ring seat 19 and at the end close to the extrusion frame 4. A plurality of second positioning cutters 25 are fixedly connected to the inner side of the third positioning circular seat 24. A limiting disc 26 is arranged on the inner side of the winding ring seat 19 and at the end away from the extrusion frame 4. A plurality of guiding pin columns 27 are fixedly connected to the inner side of the limiting disc 26. An adjusting screw 28 is threadedly connected to the center of the limiting disc 26. The adjusting screw 28 is fixedly connected to the winding ring seat 19, thereby facilitating the limiting disc 26 to drive the rubber strip to rotate on the adjusting screw 28.

[0043] During operation, the composite rubber strip extruded and formed by the extrusion frame 4 and the extrusion rod 5 is extruded into the hollow guide rod 11 inside the second positioning circular seat 10, and continues to be extruded into the first positioning circular seat 8 by the thrust of the rubber strip inside the extrusion frame 4 and the extrusion rod 5. Furthermore, after the rubber strip enters the first positioning circular seat 8, it is inserted onto the guiding pin column 27, and then drives the guiding pin column 27 and the limiting disc 26 to move away from the extrusion frame 4. During the movement, the regulating screw 28 drives the limiting disc 26 and the guiding pin column 27 to rotate on the regulating screw 28. Subsequently, the rotating limiting disc 26 and guiding pin column 27 clamp the rubber strip connected to the guiding pin column 27 onto the second positioning cutter 25 of the third positioning circular seat 24, so as to fix the extruded rubber strip.

[0044] When the rubber strip extruded through the extrusion frame 4 is positioned on the winding ring seat 19, the pneumatic cylinder moving seat 17 is started, so that the cylinder moving seat 17 drives the winding ring seat 19 and the rubber strip fixed thereto to move away from the extrusion frame 4 on the moving air column 6 and the moving rod 16. When the winding ring seat 19 moves to the preset position, the first servo motor 14 is started. Then, the first servo motor 14 drives the first transmission gear 15 to rotate, so that the first transmission gear 15 drives the second positioning circular seat 10 to rotate on the fixed seat 7 through the annular rack 12. Furthermore, the second positioning circular seat 10 clamps the rubber strip inside it through the hollow guide rod 11 thereon and the first positioning cutter 9 on the first positioning circular seat 8.

[0045] When the winding ring seat 19 moves to a suitable position and the composite rubber strip is positioned by the second positioning circular seat 10 and the first positioning circular seat 8, the second servo motor 21 is started. Then, the output end of the second servo motor 21 drives the second transmission gear 22 to rotate. Furthermore, the second transmission gear 22 drives the winding ring seat 19 and the composite rubber strip fixed thereto to wind through the transmission annular gear 23, so that the drawn rubber strip is wound into a twist shape. When heating and stretching the rubber, the molecular chains elongate along the stretching direction and are partially untangled to form an oriented arrangement structure, improving the ductility of the rubber compound. After winding, the number of cross-linking points increases, and the molecular chains are more tightly combined, which can delay the crack propagation and improve the durability of the rubber product. The spiral structure of the twist coil can fill the voids, reduce the bubbles and impurity residues at the fusion interface, improve the overall density, and facilitate the mixing of the rubber mixed at low temperature through stretching and winding, improving the mixing effect of its internal materials, reducing the uneven mixing caused by lump extrusion, and reducing the quality problems in the compounding of the composite rubber.

[0046] Example 3, as Figure 6 and Figure 7As shown in the figure, in order to facilitate the removal of the wound composite rubber from the winding ring seat 19, a extraction frame 29 is fixedly connected to the end of the moving air column 6 away from the extrusion frame 4. A fixed ring seat 30 is fixedly connected to the bottom of the extraction frame 29. An extraction positioning column 31 is snap-connected to the inner side of the fixed ring seat 30. The extraction positioning column 31 is slidably connected to the second positioning cutter 25 and the adjusting screw 28 respectively. The end of the extraction positioning column 31 close to the extrusion frame 4 penetrates through the first positioning round seat 8 and the second positioning round seat 10 respectively and is snap-connected to the extrusion frame 4.

[0047] During operation, when the winding of the composite rubber strip on the winding ring seat 19 is completed, the staff starts the first servo motor 14. Then the first servo motor 14 continues to drive the annular rack 12 and the second positioning round seat 10 to rotate. By the rotation of the second positioning round seat 10, the rubber strip on the first positioning cutter 9 and the hollow guide rod 11 is cut off. Then the staff pulls out the extraction positioning column 31 in the direction away from the extrusion frame 4. Then by moving the extraction positioning column 31 back and forth, the extraction positioning column 31 pulls the wound composite rubber on the winding ring seat 19 off the limit disc 26. Then the staff reverses the limit disc 26 to make it return to its original position for convenient use next time.

[0048] Example 4, as Figure 1 and Figure 2 As shown in the figure, a low-temperature feeding seat 32 is fixedly connected to the top end of one end of the low-temperature mixer 2 away from the extrusion frame 4. A low-temperature feeding barrel 33 is fixedly connected to the top end of the low-temperature feeding seat 32.

[0049] A high-temperature feeding barrel 34 is fixedly connected to the top end of the operation body 1 and at the position at the bottom end of the low-temperature mixer 2. A high-temperature refining machine 35 is fixedly connected to the top end of the high-temperature feeding barrel 34 and at the position corresponding to the moving air column 6.

[0050] During operation, the rubber composite material and additives to be mixed are added into the low-temperature mixer 2 through the low-temperature feeding seat 32 and the low-temperature feeding barrel 33, which is convenient for subsequent low-temperature mixing by the low-temperature mixer 2. And the subsequently low-temperature mixed and wound composite rubber enters the high-temperature feeding barrel 34 through the high-temperature refining machine 35. Then it is subjected to high-temperature mixing through the high-temperature feeding barrel 34. By high temperature, the viscosity of the rubber compound is reduced and the fluidity is enhanced, which is convenient for subsequent processing such as calendering and extrusion. Furthermore, the effect of compounding various different materials in the composite rubber is improved, and the quality of the composite rubber production is improved.
