With the development of mixer, mixing the materials for each vehicle, more and more speed faster and faster, artificial feeding in the mixing cycle, the percentage of time occupied by more and more seriously affect the efficiency of internal extrusion line the quality of play and mix. In addition, with the development of enterprises, many of the necessary materials, are required to rely on manual handling, weighing, feeding, labor intensity greatly. Very fine particles of carbon black in particular, the processes through which people and serious environmental pollution, and carbon black exposure and transport vehicles to get there on the pollution there. Exhaust pollution emissions on the shop floor improvements into the air (though filtered) on the surrounding areas have a large impact. In order to play a mixer efficiency, reduce labor intensity and the pollution of the environment, the urgent need for mixer mixing the material required for the transport, storage, weighing, feeding and other aspects of the implementation of mechanization and sheet machine. In this context, the auxiliary has successfully developed a variety of devices and applications, of which carbon black of the transportation, storage, weighing, feeding and other equipment, although after several years of improvement, but because of the characteristics of carbon black, often the problem still occurs. In general, most of the current on the auxiliary part has been automated, and when not in use on the auxiliary comparison, the advantages are obvious, are:
1. Environmental pollution has improved over the past around in the plate machine, scattered carbon black dust, and sometimes a thick layer. Mixer operators are black from head to toe, went there to scattered there. Now, in normal production conditions, the mixer operator of pollution around the situation has greatly improved.
2. Mixer mixing efficiency because of mechanization and water well drilling rig on the auxiliary, in addition to raw rubber compound also known as the man moved to the weighing, the carbon black, filler, oil can be automatically weighing and feeding. In 40 ~ 60r/min the mixer on the feeding of raw rubber, etc. can be completed in 10 to 20 seconds, the carbon black feed generally completed in 15 to 40 seconds, the injection of fuel usually takes 10 to 20 seconds range. This type of mixer 270 in 40r/min masterbatch mixing on the cycle of about 180 seconds, feeding time in the 40 to 60 seconds, about mixing cycle, 1 / 4 to 1 / 3.
3. Mix quality increased steadily in the past because of mattress machine feeding, first, when the input materials are scattered, and sometimes more accurate formula of the compound; Second, the time of input materials are sometimes long and Drilling rig short, affecting the mixing accurate implementation process specification. All these have brought about fluctuations in mix quality. Automatically feed in the auxiliary, the compound significantly improved the quality of stability.
