Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly processing and manufacturing, and in particular to an environmentally friendly rubber processing and manufacturing method. Background Art

[0002] The processing and manufacturing steps of rubber mainly include raw material preparation, plastication, mixing, molding, vulcanization, cooling, and finished product inspection and packaging. In the rubber processing process, in order to ensure the output quality of rubber, it is also necessary to perform corresponding tests on it. The extrusion method is a commonly used rubber plasticity test method, that is, under a certain temperature, pressure, and die shape, the extrusion speed of the rubber is measured to form the required rubber sealing ring for use with different pipelines and sealing requirements. Among them, a silicone rubber compound rubber detector is disclosed in a Chinese patent, and the publication number is CN216485041U. This instrument solves the problem that the existing detector is poor in operation convenience and cannot meet the user's operation needs;

[0003] However, in the current processing and production of rubber, the degree of plasticization is mainly limited by simply adjusting the plasticization time. The plasticity and fluidity of the rubber can only be directly tested after the plasticization is completed. It is impossible to achieve direct and synchronous testing of the plasticization quality, resulting in a lag in the control of plasticization quality. The performance of the rubber after plasticization is prone to deviate too much from the performance requirements, which not only affects subsequent processing, but also easily generates waste, increasing the environmental burden.

A thermometer 2051 is embedded and installed at the top of the gas control box 205 near the side of the return air pipe 225, so as to dynamically control the heat exchange process by using the exhaust gas, thereby improving the convenience of regulating the heat exchange work.

[0068] The working principle and use process of the present invention are as follows: before processing and manufacturing rubber, the machine base 100 is first placed stably on the ground, and the filter box 2061 is pulled out. According to the type of rubber actually processed, that is, the gas composition generated during the rubber processing, the corresponding filter medium is filled into the filter box 2061 to purify the harmful gas generated during the rubber mixing process. Then, the raw materials can be added into the mixing base 104, the press machine 101 is started, the top bolt 102 is driven to pressurize the raw materials, and the driving mechanism 105 is started to drive the rotors 106 to rotate in opposite directions to perform the rubber mixing process;

[0069] In this process, the raw material is brought into the gap between two rotors 106 with spiral edges, speed ratio and relative rotation under the action of the pressure and friction of the top bolt 102. In the kneading system composed of the rotors 106 and the rotors 106, the rotors 106 and the inner wall of the mixing seat 104 and the top bolt 102, the raw material is continuously pushed from the side of the return head 325 to the side of the extrusion head 314, and after being pushed to the limit, it is reversely rolled back from the outside of the rotor 106, and is subjected to the strong kneading action of constantly changing and repeated shearing, tearing, stirring, folding and friction, so that the material is destroyed and heated, resulting in oxidation chain scission and increasing plasticity.

[0070] At the same time, the rotor 106 will also drive the gear 210 to rotate synchronously, forcing the push plate 208 to move back and forth under the push of the tooth plate 209, squeezing the refrigerant on both sides and destroying the equilibrium state of the refrigerant. Under the flow limiting effect of the connecting valve 211, the refrigerant in the storage box 201 is continuously extracted and pressed into the heating box 203, forcing the pressure inside the storage box 201 to drop and the pressure inside the heating box 203 to increase accordingly. In addition, the flow blocking effect of the resistance plug 214, that is, only when the pressure inside the heating box 203 is sufficient to overcome the pressure of the refrigerant in the equilibrium state inside the gas push groove 213 on the resistance plug 214, can the resistance plug 214 slide under the pressure inside the heating box 203;

[0071] That is, only when the pressure inside the heating box 203 is greater than the critical pressure of the refrigerant, the refrigerant inside the heating box 203 can push the resistance plug 214 to slide, so that the strip groove 215 is connected, and the refrigerant flows through the return pipe 212 and the strip groove 215 to the inside of the storage box 201, and circulates in this way, forcing the refrigerant to quickly vaporize and absorb heat in the storage box 201 due to the pressure drop, and quickly liquefy and release heat in the heating box 203 due to the pressure increase;

[0072] While the push plate 208 reciprocates, it will drag the piston plate 221 to reciprocate inside the piston seat 204 through the connecting rod 220. Under the flow restriction of the check valve 219, the external air is forced to be filtered by the filter head 2191 and then drawn into the piston seat 204, and then pressed into the heating pipe 216 and the cooling pipe 217 respectively through the corresponding air outlet pipe 218, and are respectively heated and cooled by the external refrigerant to turn into cold air flow and hot air flow, and then the hot air flows through the top guide pipe 222 into the air control box 205, and the cold air flows through the bottom guide pipe 222 into the air control box 205, and then flows into the air distribution seat 207 through the heat mixing pipe 224, and after secondary diversion by the air distribution seat 207, it is evenly sprayed into the inner cavity of the internal mixer seat 104, so as to directly regulate the internal temperature of the internal mixer seat 104;

[0073] Then the airflow will carry the exhaust gas generated during the banburying process and enter the space located on one side of the return air pipe 225 inside the air control box 205 through the return air pipe 225. The exhaust gas temperature can be observed through the temperature meter 2051, and the exhaust gas temperature corresponds to the current banburying temperature. At this time, air is injected into the air control box 205 through the valve 2000 on the air control box 205 to adjust the air pressure on the cross plug 223, which is the temperature balance air pressure.

[0074] During this process, the pressure change of the exhaust gas will change synchronously with the temperature. When the exhaust gas pressure is lower than the temperature equilibrium pressure, the cross plug 223 will move toward the return pipe 225, forcing the hot air flow opening of the top guide pipe 222 to become larger. Conversely, the exhaust gas will push the cross plug 223 to move in the opposite direction, forcing the cold air flow opening of the bottom guide pipe 222 to become larger.

[0075] Since the piston plate 221 pushes the airflow at a constant speed, that is, the total amount of hot airflow and cold airflow is constant, the temperature balance pressure is limited according to the reading of the temperature meter 2051, and the balance pressure of the tail gas can be limited, and then the hot and cold airflow ratio is adjusted, and the banburying temperature is dynamically limited. The tail gas will finally flow into the purifier 206 through the tail gas pipe 226, and be discharged into the air after being purified by the filter medium;

[0076] Similarly, during the internal kneading process, the other rotor 106 will drive the gear plate 318 to rotate synchronously, forcing the circular gear plate 317 to drive the strip plate 315 to move back and forth inside the power box 305 through the connecting rod 316, and reciprocatingly press the compressed air on both sides of the strip plate 315 into the pushing chamber 310 through the two connecting pipes 309 in turn, forcing the sliding plug 311 to drag the pressing plate 313 to move up and down reciprocatingly through the push rod 312;

[0077] During the mixing process, as the mixing progresses, the plasticity of the rubber will gradually increase. After it has fluidity, a small part of it will be squeezed into the receiving box 302 through the extrusion head 314 under the pushing and squeezing of the rotor 106, and then pressed into the pressure-resistant tube 307 through the extrusion head 306 during the lifting and lowering process of the pressing plate 313, and then pressed into the ring box 303 to push the rotating wheel 319 to rotate, and then pressed into the capillary 308, and finally pressed back to the mixing seat 104 through the return head 325;

[0078] In this process, since the lifting speed of the strip plate 315 is constant, the total amount of compressed air in the power box 305 and the pushing chamber 310 is constant, that is, during the lifting process of the strip plate 315, the pressure on the rubber inside the receiving box 302 gradually increases and the upper limit is constant. Air can be injected into the power box 305 through the valve 2000 on the power box 305 to limit the upper limit of the extrusion pressure on the rubber, so that the shaping detection work is smoother and the pre-pressure condition is provided for detecting plasticity by the extrusion method.

[0079] As the plasticity and fluidity of the rubber gradually increase, the minimum pressure required to extrude the rubber through the extruder head 306 will be reduced accordingly, that is, the rubber can be extruded with a smaller pressure during the lifting and lowering process of the strip plate 315, and the effective stroke of the strip plate 315 for extruding the rubber becomes longer. In one lifting and lowering process, more rubber can be pressed into the ring box 303, and the extrusion speed of the rubber material becomes larger accordingly, thereby forcing the rotating wheel 319 to rotate faster, and the corresponding turbine 320 will rotate faster under its drive, pulling the external airflow to enter the air guide head 321 faster from the bottom opening of the turbine box 304, and flow out from the flow channel 323;

[0080] That is, under the pre-pressure condition, with the die restriction of the extruder head 306 and the temperature restriction of the exhaust temperature control mechanism 200, as the plasticity of the rubber increases, the extrusion speed of the rubber material will increase accordingly, which directly leads to an increase in the velocity of the airflow flowing out of the flow channel 323, and the airflow pressure on the resistance core 322 will increase accordingly. Here, the airflow pressure on the resistance core 322 and the gram weight of the rubber material extruded per minute in the extrusion method are both direct reflections of the extrusion speed of the rubber material, that is, the size of the airflow pressure on the resistance core 322 can be equivalently used to detect the plasticity of the rubber by the extrusion method;

[0081] When the airflow pressure on the resistance core 322 overcomes the air pressure on the other side, it indicates that the plasticity of the rubber has reached the standard, and the resistance core 322 will slide accordingly under its pressure and no longer press the switch 324. At this time, the switch 324 will control the driving mechanism 105 to sleep, and the air inside the air guide head 321 can be filled and discharged through the valve 2000 on the air guide head 321, and the standard value of the plasticity conversion pressure can be limited to achieve direct control of the plasticity of the rubber;

[0082] After the mixing work is completed, the push pin 102 is driven to return to its original position by the press machine 101, and the mixing seat 104 is controlled by the turning mechanism 103 to remove the mixed rubber, and then the subsequent processing work can be carried out.

[0083] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
