When the mixing temperature is too high, the thermal-oxidative aging of rubber can be accelerated, so that the physical and mechanical properties of vulcanized rubber are reduced, namely, the phenomenon of over-mixing occurs; the rubber material can be burnt, so effective cooling measures must be adopted in the mixing process of the internal mixer; but not too low, otherwise the compound will collapse.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the utility model. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1, the driving double-speed-regulation rubber internal mixer comprises a base 1, an internal mixing chamber 2, a material pressing mechanism 3, a double-motor driving device 4, wherein the internal mixing chamber 2 and the double-motor driving device 4 are both fixed on the base 1, the material pressing mechanism 3 is positioned on the internal mixing chamber 2, and the internal mixing chamber cooling device 5 is further included.
The two motors of the double-motor driving device 4 are respectively connected with the two rotors in the mixing chamber 2 through speed reduction motors, the material pressing mechanism 3 is used for compacting raw materials in the mixing chamber 2, and the mixing chamber cooling device 5 is mainly used for preventing the friction between the raw materials and the inner wall of the mixing chamber when the two rotors rotate, so that the temperature in the mixing chamber 2 rises and the quality of rubber is influenced.
As shown in fig. 2, fig. 3 and fig. 4, the mixing chamber cooling device 5 is fixed on the outer side surface of the mixing chamber 2, the mixing chamber cooling device 5 includes a housing 5.1, a plurality of heat dissipation fins 5.2 and an air blower 5.3, the heat dissipation fins 5.2 are formed by a plurality of cylindrical columns fixed on the outer side surface of the mixing chamber 2, the plurality of heat dissipation fins 5.2 are uniformly distributed on the outer side surface of the mixing chamber 2, the housing 5.1 is fixed on the outer side surface of the mixing chamber 2 through the plurality of heat dissipation fins 5.2, one end of the heat dissipation fin 5.2 is fixed on the outer side surface of the mixing chamber 2, the other end of the heat dissipation fin 5.2 is fixed to pass through the housing 5.1 to be suspended, the housing 5.1 is provided with an air inlet 5.1.1, an air outlet 5.1.2, a pressing mechanism opening 5.1.3 and a discharging mechanism opening 5.1.4, the air inlet 5.1.1 is located at the lower end of the housing 5.1, and the air outlet 5.2 is located at the upper end of the pressing mechanism 5.1, the pressing mechanism opening 5.1.3 is located on the upper end face of the shell 5.1, the discharging mechanism opening 5.1.4 is located on the lower end face of the shell 5.1, and an air inlet pipe of the air blower 5.3 is connected with the shell 5.1 through the air inlet 5.1.1.
When the temperature in the mixing chamber 2 is detected to rise, the air blower 5.3 is started, and then cold air in the environment blows into the outer shell 5.1, and because the heat dissipation fins 5.2 dissipate the temperature in the mixing chamber 2, the cold air in the environment blows heat on the heat dissipation fins 5.2 directly out of the air outlet 5.1.2.
Since the specific heat capacity of water is large, if water is used as the temperature reducing medium, and since the maximum temperature of water is 100 degrees, the water will be directly evaporated above the temperature, and thus, the use of water as the temperature reducing medium is not suitable.
When the double-motor internal mixing device is used, the internal mixing chamber 2 is heated firstly, the double-motor driving device 4 is started, then feeding is carried out, after feeding, if the temperature is detected to rise to a certain value, the air blower 5.3 is started, and cold air in the environment can take away heat on the heat dissipation fins 5.2. The heat sink fins 5.2 extend outside the housing 5.1, mainly to enhance heat dissipation, and to balance the temperature of the heat sink fins 5.2 inside the housing 5.1. The reason is that when the cold air in the environment takes away a large amount of heat, if the temperature in the mixing chamber 2 is reduced too fast, the mixing effect will be affected, the air blower 5.3 is turned off in time, and the heat dissipation fins 5.2 suspended outside the outer shell 5.1 can replenish the lost heat.
The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the utility model according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
