Description

Technical Field

[0001] The invention belongs to the technical field of rubber production and relates to equipment for preparing a high-strength, ageing-resistant polymer rubber composite material. Background Art

[0002] Nowadays, the industry generally uses anti-aging agents to improve the durability of rubber. These anti-aging agents can be divided into antioxidants, anti-ozonants, anti-fatigue agents and anti-UV agents according to their functions. By mixing natural rubber with synthetic materials such as styrene-butadiene rubber or butadiene rubber, the aging resistance of rubber can be significantly improved, while improving the plasticity and dimensional stability of the rubber, which helps to reduce production costs.

[0003] When mixing and kneading existing rubber composite materials, most of the temperatures are controlled at 80~100°C. In order to avoid premature reaction of the vulcanizer and the accelerator, the upper limit temperature is generally not more than 110~115°C. However, when mixing rubber composite materials, 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 no more than 130°C for EPDM. When the existing mixer melts and mixes different materials through temperature setting, if the temperature is not properly controlled, problems such as poor dispersion of the composite material, poor compatibility, uneven density, and abnormal plasticity may easily occur.

[0004] Therefore, according to the above technical problems, a preparation device for high-strength aging-resistant polymer rubber composite material is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is that when the existing rubber composite materials are mixed and kneaded, most of the temperatures are controlled at 80-100°C.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, the composite material to be processed is preheated to 50-70°C by a low-temperature mixer to soften it, and then the softened composite material is extruded into long strips using a mixing screw and an extrusion frame. During the preheating and mixing at 50-70°C, corresponding additives are added thereto so that the additives and the composite material are integrated with each other. This is the first stage of mixing, and then the second stage of high-temperature mixing is performed. Through the composite step of the layered temperature, the oxidation and thermal aging of the rubber are inhibited by low temperature, the molecular chain integrity of the polar rubber is protected, and the burning problem is avoided.

The cross-linking points after winding increase, and the molecular chains are more tightly bonded, which can delay crack propagation and improve the durability of rubber products. The spiral structure of the twisted roll can fill the gap, reduce the bubbles and impurity residues at the fusion interface, and improve the overall density. It is convenient to mix the low-temperature mixed rubber through stretching and winding, improve the mixing effect of its internal materials, reduce the uneven mixing caused by mass extrusion, and reduce the quality problems in the mixing of composite rubber.

[0022] During operation, the composite material to be processed is preheated to 50-70°C by the low-temperature mixer 2 to soften it, and then the softened composite material is extruded into long strips using the mixing screw 3 and the extrusion frame 4.

[0025] In order to facilitate the pulling out of 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. The inner side of the first positioning round seat 8 is fixedly connected with the moving rod 16, the outer sides of the moving air column 6 and the moving rod 16 are slidably connected with the cylinder moving seat 17, the bottom end of the cylinder moving seat 17 is fixedly connected with the fixed ring frame 18, and the inner side of the fixed ring frame 18 is rotatably connected with the winding ring seat 19, so as to facilitate the winding ring seat 19 to slide on the moving air column 6 through the moving rod 16 and the cylinder moving seat 17, so that it is convenient to drive the composite rubber strip to be pulled out from the extrusion frame 4.

[0026] The winding assembly also includes a winding frame 20, a second servo motor 21, a second transmission gear 22 and a transmission ring gear 23. In order to facilitate the rotation of the winding ring seat 19 in the fixed ring frame 18, the end of the cylinder moving seat 17 away from the extrusion frame 4 is fixedly connected to the winding frame 20, the bottom of the winding frame 20 and the end away from the extrusion frame 4 is fixedly connected to the second servo motor 21, the bottom of the winding frame 20 and the end close to the extrusion frame 4 is rotatably connected to the second transmission gear 22, the output end of the second servo motor 21 is fixedly connected to the second transmission gear 22, the end of the winding ring seat 19 away from the extrusion frame 4 is fixedly connected to the transmission ring gear 23, and the second transmission gear 22 is meshed with the transmission ring gear 23, so as to facilitate the second servo motor 21 to drive the second transmission gear 22 and the winding ring seat 19 to rotate.

[0027] The winding assembly also includes a third positioning round seat 24, a second positioning knife 25, a limiting disc 26, a guide needle column 27 and an adjusting screw 28. In order to facilitate the fixation of the composite rubber strip extruded by the extrusion frame 4 and the extrusion rod 5, the inner side of the winding ring seat 19 and the end close to the extrusion frame 4 is fixedly connected with the third positioning round seat 24, the inner side of the third positioning round seat 24 is fixedly connected with a plurality of second positioning knives 25, the inner side of the winding ring seat 19 and the end away from the extrusion frame 4 is provided with a limiting disc 26, the inner side of the limiting disc 26 is fixedly connected with a plurality of guide needle columns 27, the center thread of the limiting disc 26 is connected with the adjusting screw 28, the adjusting screw 28 is fixedly connected to the winding ring seat 19, so as to facilitate the limiting disc 26 to rotate with the rubber strip on the adjusting screw 28.

[0028] During operation, the composite rubber strip extruded by the extrusion frame 4 and the extrusion rod 5 is squeezed into the hollow guide rod 11 in the second positioning round seat 10, and continues to be squeezed into the first positioning round seat 8 through the thrust of the rubber strip in the extrusion frame 4 and the extrusion rod 5. After entering the first positioning round seat 8, the rubber strip is inserted into the guide needle column 27, and then drives the guide needle column 27 and the limiting disc 26 to move in the direction away from the extrusion frame 4. During the movement, the limiting disc 26 and the guide needle column 27 are driven to rotate on the adjusting screw 28 by the adjusting screw 28, and then the rotating limiting disc 26 and the guide needle column 27 clamp the rubber strip connected to the guide needle column 27 on the second positioning clamping knife 25 of the third positioning round seat 24, so that the extruded rubber strip is fixed.

[0029] After the rubber strip extruded by 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 thereon to move in a direction 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, and 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 round seat 10 to rotate on the fixed seat 7 through the annular rack 12, and then the second positioning round seat 10 clamps the rubber strip inside it through the hollow guide rod 11 thereon and the first positioning clamping knife 9 on the first positioning round seat 8.

[0030] When the winding ring seat 19 moves to a suitable position and the composite rubber strip is positioned by the second positioning round seat 10 and the first positioning round seat 8, the second servo motor 21 is started, and the output end of the second servo motor 21 drives the second transmission gear 22 to rotate, and the second transmission gear 22 drives the winding ring seat 19 and the composite rubber strip fixed thereto to wind through the transmission ring gear 23, so that the extracted rubber strip is wound into a twist shape. When the rubber is heated and stretched, the molecular chain stretches along the stretching direction and partially unwinds to form a directional arrangement structure, which improves the ductility of the rubber material, increases the cross-linking points after winding, and makes the molecular chains more tightly bonded, which can delay crack propagation and improve the durability of rubber products. The spiral structure of the twist roll can fill the gap, reduce the bubbles and impurity residues at the fusion interface, and improve the overall density. It is convenient to mix the low-temperature mixed rubber by stretching and winding, improve the mixing effect of its internal materials, reduce the uneven mixing caused by mass extrusion, and reduce the quality problems in the mixing of composite rubber.

The end of the extraction positioning column 31 close to the extrusion frame 4 passes through the first positioning round seat 8 and the second positioning round seat 10 respectively and is clamped and connected to the extrusion frame 4.

[0032] During operation, when the composite rubber strip on the winding ring seat 19 is wound, the staff starts the first servo motor 14, and then the first servo motor 14 continues to drive the annular rack 12 and the second positioning round seat 10 to rotate, and the rubber strips on the first positioning knife 9 and the hollow guide rod 11 are cut off by the rotation of the second positioning round seat 10, and then the staff pulls out the extraction positioning column 31 in the direction away from the extrusion frame 4, and then moves the extraction positioning column 31 back and forth, so that the extraction positioning column 31 pulls the composite rubber wound on the winding ring seat 19 off the limiting disc 26, and then the staff reverses the limiting disc 26 to restore it to its original position for the next use.

[0034] A high-temperature feed barrel 34 is fixedly connected to the top of the operating body 1 and the position at the bottom of the low-temperature mixer 2 , and a high-temperature heat mixer 35 is fixedly connected to the top of the high-temperature feed barrel 34 and the position corresponding to the moving air column 6 .

[0035] During operation, the rubber composite material and additives to be mixed are added into the low-temperature mixer 2 through the low-temperature feed seat 32 and the low-temperature feed barrel 33, so as to facilitate the subsequent low-temperature mixing by the low-temperature mixer 2, and the composite rubber after subsequent low-temperature mixing and winding enters the high-temperature feed barrel 34 through the high-temperature hot mill 35, and then is mixed at high temperature by the high-temperature feed barrel 34, so as to reduce the viscosity of the rubber material and enhance the fluidity by high temperature, so as to facilitate the subsequent processing such as calendering and extrusion, thereby improving the compounding effect of various materials in the composite rubber and improving the quality of the composite rubber production.
