The meshing rotor is adopted, most of the turnover internal mixers adopt shearing rotors, the meshing rotor is adopted, the rotor configuration is independently researched and developed, and the application of the meshing rotor on the turnover internal mixer is filled. Compared with the traditional turnover internal mixer, the turnover internal mixer has the following advantages and innovation points:
the mixing system consists of a rear rotor, a front rotor, an upper top bolt, a left side plate of a mixing chamber, the mixing chamber and a right side plate of the mixing chamber. Each part is provided with a cooling/heating water channel, thereby realizing forced pressurization circulating cooling, having high cooling/heating efficiency, ensuring the temperature consistency of a mixing area,
the meshed rotor is independently developed, and has the advantages that: the device is used for experiment, and when a large meshing type rotor is cast and formed, a water channel is cast and formed. For experimental equipment, the cost of separately arranging a set of grinding tool as a rotor model is high, and the appearance size is not easy to guarantee. The rotor of the equipment is directly formed by a machining center, and two circulating cooling/heating water channels are arranged in the internal cooling water channel, wherein one is a spiral groove type, and the other is a straight groove type. The two modes can realize strong pressure circulation, relative to the convenience of processing, the subsequent pressure circulation is easier to realize, the cost is lower, and the temperature control of the rotor of the core component of the mixing chamber can be effectively ensured by the strong pressure circulation cooling. The advantages are two: in the process of rubber mixing, a meshed structure is modified, a rubber baffle plate is additionally arranged, a certain gap is reserved between the two short edges and the rubber baffle plate, and the flowability of rubber materials between a rotor and an internal mixing chamber is ensured. The advantages are three: the outer fringe of rotor has set up and has kept off the rubber disc, and the outside of cooperation rotor is sealed airtight, and it is better to seal the effect. The rotor is sealed by adopting spring type external pressure end face sealing, and is provided with a grease pump, grease or oil is injected into a sealed gap for sealing, and small materials such as rubber, carbon black and the like are effectively sealed;
and secondly, a coupler and a speed ratio gear of the device are combined and combined together. The gear of the gear coupling is combined with the gear of the gear ratio gear I to form the gear coupling. The structure is compact, two functions are realized by one structure, the integrated speed ratio coupler is placed in a speed ratio gear box, oil lubrication is adopted, the transmission efficiency is ensured, and the friction force caused during overturning is reduced;
the driving system of the equipment adopts conventional three-phase motor to output power, and consists of three-phase motor, elastic cancelling coupler, hard tooth surface accelerator and integral speed ratio coupler, and adopts the connection mode of motor + coupler + reducer + coupler + speed ratio gear. In the internal mixer during the upset of with specification, the effectual input that promotes the power has guaranteed the work efficiency when plasticating mixing. The whole machine adopts a direct connection mode, so that the service life is longer, and the power output is more stable;
the material pressing system of the equipment mainly comprises an upper top bolt cylinder and an upper top bolt, the upper top bolt is larger due to the fact that a feeding port of the turnover internal mixer is also a discharging port, the contact area of the upper top bolt and the material is larger, and small holes are drilled in an upper top bolt body of the equipment for cooling/heating to ensure the mixing temperature in the mixing chamber
The turning part and the pressing part are both pneumatically driven, the turning cylinder drives the turning mechanism, the turning angle can reach 115 degrees, and the upper dead point and the lower dead point are avoided.
